midwife-turned-immunization coordinator Nur Khalida has been based at Puskesmas Ingin Jaya
on the outskirts of Banda Aceh City.
Nur works with local midwives on how best to improve immunization coverage
focusing on addressing vaccine hesitancy.
\"I believe in using a personal approach to build trust with the community,” she explains
“I always offer my phone number for follow-up questions
which helps alleviate fears.”

These practical sessions on immunisation administration and role-playing exercises helped participants effectively explain diseases and vaccinations to parents
recent outbreaks of vaccine-preventable diseases such as measles
polio and diphtheria have highlighted the urgent need to improve immunization coverage
just 20.8% of children in Aceh were fully immunized
well below the national average of 95.3%.
well-trained and empowered health workers can boost vaccine acceptance
protect communities and ultimately save lives.
“Health workers are the bridge between public health policies and the communities they serve,” explains Dr Muhammad Fathun
WHO Technical Officer for vaccination in Aceh
“It’s not enough to simply offer vaccines; they must be able to communicate
educate and earn people’s trust.”
This simple yet crucial observation was the foundation of a Ministry of Health (MoH) and World Health Organization (WHO)-supported training in Banda Aceh City
Trainers demonstrated how to identify frozen vaccines
“Many people in the community fear adverse events following immunization or face opposition from family members
particularly fathers,” says Dr Fathun
we addressed these concerns with participants through practical role-playing exercises.”
frontline health workers are the ones who have the most direct contact with families
so they need to be equipped with the right tools and communication skills to address community concerns in a compassionate and understanding way.\"
The MoH and WHO-supported training was conducted in two five-day batches
bringing together 180 participants from 7 districts in the province
This included 102 immunization officers and 78 midwives
In addition to community engagement and education
the training covered key skills such as microplanning and vaccine cold chain management
including how to identify frozen vaccines.
Participants engage in hands-on record keeping and cold chain management training at a Puskesmas
Sessions were also held on reporting immunization programme implementation
surveillance of adverse events following immunization
and monitoring and evaluating immunization activities
Nur notes that both the content of the training and the participants marked a significant shift from earlier approaches.
training for central health office staff was prioritized
while training for midwives and immunization officers was minimal.
the immunization officers often knowing who was vaccinated and who was not.
gaps are being bridged – one health worker at a time.
This activity was supported by the Australian government through the Department of Foreign Affairs and Trade
"I believe in using a personal approach to build trust with the community,” she explains
so they need to be equipped with the right tools and communication skills to address community concerns in a compassionate and understanding way."

Outdoor dining venue at Ristorante Fieni's in Voorhees
Ristorante Fieni’s has been a staple of the dining scene in South Jersey
the popular Italian BYOB in Voorhees was immediately impacted by COVID-19 and its dining room's closure
shifting to takeout and delivery was a no-brainer
With outdoor dining now allowed and indoor dining shelved
the restaurant has a positive outlook for now
"Fortunately for us, we offered takeout before the pandemic and eventual shutdown. So we doubled down on what we offered and changed our whole system to accommodate carry out," Marco Fieni told 70and73.com
"We spent the first few days stocking up on everything we possibly could and learning and tweaking as we went along."
Recognizing that the shutdown would be long-term
Fieni knew that adapting the way the restaurant did business and communicating with its customer base would be essential to keep the restaurant in business
"We documented every step along the way across all our social media accounts," noted Fieni
Getting the word out and keeping people updated was especially important when outdoor dining was initially permitted
Fieni updates the restaurant’s Facebook page daily with photos of the outdoor patio dining area
"We’ve offered outdoor seating on our patio for a few years now
We always used it to help supplement demand
especially on the weekends when the weather was nice," Fieni said
"We have approximately 20 to 25 seats available outside depending on party sizes
we can section off some areas of our parking lot as well."
Striving to Thrive is a series of articles that look at how South Jersey businesses are faring in the COVID-19 pandemic and how they may change as we emerge from the crisis. Ideas or suggestions? Email contactus@70and73.com
Outdoor dining has been a nice supplement to the takeout business
the business has been solid overall without having to go back to a reservation-based system
"We decided to accept walk-ins only because the weather is a factor," mentioned Fieni
"The last thing we’d like to do is disappoint anyone."
Eager to safely welcome back guests inside
Fieni was ready to open up the dining room even at 25% capacity and strict guidelines on July 2
It would have provided a nice boost in business over the Fourth of July weekend
but he’s optimistic this delay is not a catastrophe
"It’s business as usual for outdoor dining and takeout with occasional requests for catering business."
Safety is at the top of his mind and he’s prepared to keep doing what it takes to remain open and keeping staff and customers safe and healthy in the outdoor dining area
"Tables are spaced six feet apart from one another and groups are capped at a maximum of eight guests per table," Fieni explained
"All employees are required to wear masks and gloves in addition to hand washing and sanitizing
We are using disposables as much as possible — menus
peppers and other condiments in particular
We also have sanitizer stations located throughout."
Undeterred by all of the changes and continued uncertainty
Fieni is hopeful the longtime family-owned and operated business will withstand these chaotic times

The development of selective and nontoxic immunotherapy targeting prostate cancer (PC) is challenging
Interleukin (IL)30 plays immunoinhibitory and oncogenic roles in PC
and its tumor-specific suppression may have significant clinical implications
CRISPR/Cas9-mediated IL30 gene deletion in PC xenografts using anti-PSCA antibody-driven lipid nanocomplexes (Cas9gRNA-hIL30-PSCA NxPs) revealed significant genome editing efficiency and circulation stability without off-target effects or organ toxicity
Biweekly intravenous administration of Cas9gRNA-hIL30-PSCA NxPs to PC-bearing mice inhibited tumor growth and metastasis and improved survival
Cas9gRNA-hIL30-PSCA NxPs suppressed ANGPTL 1/2/4
EGF and HGF expression in human PC cells while upregulated CDH1
leading to low proliferation and extensive ischemic necrosis
IL30-targeting immunoliposomes downregulated NFKB1 expression and prevented intratumoral influx of CD11b+Gr-1+MDCs
and prolonged host survival by inhibiting tumor progression
This study serves as a proof of principle that immunoliposome-based targeted delivery of Cas9gRNA-IL30 represent a potentially safe and effective strategy for PC treatment
given that PC mainly affects patients older than 50 years of age
an increase in new cases is expected in the near future due to population aging
great strides in therapy have not been made
The development of personalized treatments that are well-tolerated by elderly patients with comorbidities is a major challenge and would have a high impact on the health care system
many challenges remain to be addressed to increase its efficacy
among which the delivery system plays a key role
we designed and synthesized a nonimmunogenic biocompatible cationic lipid nanocomplex coated with PEG (NxP) and conjugated with anti-PSCA antibodies (Abs) for the selective delivery of the Cas9 guide (g) RNA-IL30 complex to human (h)-derived PSCA+IL30+ PC xenografts and in a syngeneic
We demonstrated the efficient uptake of Ab-conjugated Cas9gRNA-IL30 NxPs in PC cells both in vitro and in vivo
tumor-selective suppression of IL30 signaling pathways and remodeling of the intratumoral immune cell context
resulting in substantial tumor growth inhibition and improved survival without evident toxicity
Our investigation provides a proof of concept that immunoliposome delivery of the Cas9gRNA-hIL30 complex for IL30 genome editing at the tumor site is a clinically valuable tool for the safe and effective immunotherapy of PC
The cell lines were cultured in RPMI-1640 with 10% FCS (Seromed
confirmed to be mycoplasma-free by PCR analysis
and passaged for fewer than 6 months after initial thawing
PSCA expression on DU145, PC3, wild-type TRAMP-C1 and IL30-TRAMP-C1 cells and the conjugation efficiency between the anti-PSCA Abs and the aldehyde-modified DSPE-PEG2000 lipid present on the external layer of the NxP were assessed using flow cytometry, as described in the Supplementary Methods
Cationic lipid nanocomplexes coated with PEG (NxP) were synthesized using a microfluidic device from Dolomite Microfluidics (Royston, UK) and lipids, as described in detail in the Supplementary Methods
by the European Medicines Agency (EMA) and Food and Drug Administration (FDA)
The encapsulation efficiency of Cas9gRNA-IL30 into nanoliposomes and the release rate of the Cas9IL30 NxPs were determined as reported in the Supplementary Methods
Whole-genome next-generation sequencing (NGS) was performed by Lexogen GmbH (Wien
Austria) using the Illumina NovaSeq 6000 platform system and Dragen software
The intracellular uptake of NxPs by PC cells in vitro was analyzed using TEM, as reported in the Supplementary Methods
PC cell viability and proliferation after treatment with empty NxPs or Cas9IL30-loaded NxPs were assessed using the CellTiter 96 AQueous One Solution Cell Proliferation Assay (#G3582; Promega
USA) according to the manufacturer’s instructions
Mice weight was constantly monitored for 63 days
consistent with the longest treatment schedule duration (12 administrations
Histopathological and ultrastructural analyses of the intracellular uptake and toxicity of NxPs in vivo were performed as described in the Supplementary Methods
Laser scanning confocal (LSC) microscopy analyses of the lung transit and tumor uptake of the NxPs were performed as described in the Supplementary Methods
3 groups of 5 PC3 and 3 groups of 5 DU145 tumor-bearing NSG mice and 3 groups of 5 TRAMP-C1 tumor-bearing C57BL/6J mice were i.v
treated when the tumors reached a mean volume of ~700 mm3
with Cas9hIL30 NxPs or Cas9mIL30 NxPs conjugated or not conjugated with anti-PSCA Abs or free Cas9 (in PBS) at a dose of 1.5 mg of Cas9 equivalent/kg
blood was collected at predetermined time intervals (5 min
The biodistribution of NxPs and their efficiency in targeting the tumor site were determined by using a 3T scanner (Philips Medical Systems, Nederland), as described in the Supplementary Methods
Analysis of Cas9 protein in tumors and organs from NSG mice treated with anti-hPSCA Ab-conjugated or unconjugated NxPs was performed as reported in the Supplementary Methods
Eight-week-old NSG male mice were purchased from Charles River (Wilmington, MA, USA) and housed under high barrier conditions according to the Jackson Laboratory’s guidelines (https://www.jax.org/jax-mice-and-services/find-and-order-jax-mice/nsg-portfolio/housing-and breeding-considerations-for-nsg-mice) in the animal facility of the Center for Advanced Studies and Technology at the “G

To study the effects of IL30-targeted treatment on the tumor immune microenvironment and tumor behavior
three groups of twenty-seven 8-week-old C57BL/6J male mice were s.c
injected with 5 × 105 mIL30 lentiviral-DNA-transfected TRAMP-C1 cells (IL30-TRAMP-C1)
Mice were treated with Cas9IL30-PSCA NxPs, empty-PSCA NxPs, or PBS as soon as the tumors became palpable and twice a week thereafter, as shown in Supplementary Fig. 3
Two additional groups of twenty-seven 8-week-old NSG male mice were s.c
injected with nontargeting guide RNA-transfected (NTgRNA) or IL30 knockout (IL30KO) DU145 or PC3 cells
whereas an additional group of twenty-seven 8-week-old C57BL/6J male mice was s.c
These control groups were monitored for tumor growth but were left untreated
Tumors were measured with calipers as soon as they were palpable (2 mm in diameter)
Based on the tumor growth and progression rates
12 mice from each group were euthanized at (4) key time points (3 mice per point) for histopathological and ultrastructural analyses
The remaining 15 mice per group were kept alive until tumors reached 2 cm3 or evidence of suffering was observed

Immunotherapy has been a breakthrough in the treatment of advanced tumors29
but limited results have been obtained in PC
The identification of new targetable immunosuppressive oncogenes would be useful
Given that PC mainly affects the fragile and progressively expanding elderly population
a tumor-selective and well-tolerated therapeutic approach is especially needed
Nanobiotechnology can provide innovative tools for the development of precision cancer immunotherapy
and IL30 represents a potential therapeutic target in PC
ensures efficient site-specific accumulation and favors internalization into PC cells
excluded the possibility of organ damage or obvious inflammatory responses
These data were substantiated by the lack of significant changes in weight and serum levels of inflammatory cytokines and markers of cardiac
Chronic biweekly treatment with immunoliposomes
substantially inhibited tumor growth and progression
After traveling through the pulmonary circulation
intravenously administered immunoliposomes enter the systemic circulation but exclusively accumulate in PSCA+ tumors
yielding inhibitory effects on tumor progression programs
Remodeling the TME in immunocompetent hosts is associated with substantial inhibition of tumor growth and metastasis
leading to improved survival of IL30-targeting immunoliposome-treated mice and strengthening the results obtained in xenograft tumor models
immunoliposomes that selectively target tumors and deliver a CRISPR/Cas9 complex to edit tumor-promoting and immunoregulatory genes are absent from the current therapeutic landscape
emphasizing the clinical value of an IL30-targeting therapeutic strategy
The dramatic disruption of proangiogenic and tumor progression programs and the overcoming the immunosuppressive TME
attributed to the selective nanoliposome-mediated deletion of the IL30 gene in cancer cells
paves the way for the development of a modern and safe immuno-nanotherapy for advanced PC that meets the needs of healthy aging

Prostate cancer is an age-related disease and a leading cause of cancer death in men worldwide
Although its incidence has remained stable over the past decade
the proportion of tumors diagnosed in the advanced stages is rising
highlighting the need for improved and personalized treatments
especially for older patients with additional health problems
Di Carlo and coworkers created a NanoLiposome delivery system to transport a gene-editing tool
to target and inhibit a particular gene involved in cancer growth
This study tested this approach’s effectiveness and safety on human prostate cancer cells and mouse models
The findings show the potential of using NanoLiposomes for targeted gene editing in cancer
The researchers conclude that this method could provide a new and effective way to treat prostate cancer
particularly in patients requiring gentler treatment options

Indonesia — Nestled between a vast palm oil plantation and the Sumatran rainforest is Alue Buloh
one must hike several kilometers down a mud and gravel road lined by land clearings and abandoned huts
The residents of Alue Buloh seem to never run out of stories about their interactions and encounters with elephants
“We can only accept our fate when the elephants ravage our crops,” said Junaidi
a 42-year-old farmer who lives in Alue Buloh
“The elephants will never forget their original route
if we build a house or a farm within the elephants’ corridor
Instead of killing or hurting the elephants for invading their farms
the farmers provide them with space to feed and chase them away gently using loud noises — and in some cases
Even as increasing habitat loss for the Sumatran elephant and poverty for the villagers complicate efforts to address the human-elephant conflicts
local farmers are still exhaustively conducting voluntary patrols to protect the elephants and save their livelihoods
These are the people living among the Sumatran elephants and working to conserve them along with the livelihoods of Cot Girek
Junaidi heads the volunteer elephant patrol team in Cot Girek
Protecting farmers’ livelihoods motivated him to join
“Unlike government officials who receive a monthly salary
we [farmers] can only rely on our crops for money,” he said
He added he hopes for the government to intervene and help the farmers who have to deal with human-wildlife conflicts
Junaidi said he’s encountered elephants from a very young age
“Elephants are human too — they have strong feelings,” he said
I remember seeing an elephant that fell into a canal and one of its mates immediately helped it
Elephants typically roam the village at 3 in the morning
“We use cannons and clanking noises to chase them away while saying ‘surut
an activist from SAHARA (Yayasan Suara Hati Rakyat
a local environmental NGO whose name translates into “the People’s Conscience Foundation”)
is fighting the local culture of patriarchy through her activism in Cot Girek
“Communities of women who live in secluded places that lack access [to education and information] such as Cot Girek are happy to discuss women’s rights,” she said
The community is trained to grow a variety of crops such as rosella (Hibiscus sabdariffa)
and improve their livelihoods and local economy with the use of non-timber forest products
“The groups of women here are very focused on improving the local economy,” Husna said
they lack acknowledgement when it comes to policymaking in the village.”
Kelompok Meurah is led by Junaidi’s 61-year-old mother
She said she’s tried many ways to repel the elephants from invading their houses and crops
She recalled a time when Junaidi was young and a male elephant stood before him; she asked Junaidi to recite the adzan
Maybe he would listen to us and love us.’ He recited it three times until the elephant moved back.”
The role of women is crucial in protecting the village during elephant invasions
While the men are away looking for and herding the elephants back into the jungle
the women wait at home with torches and cannons
I had to carry young Junaidi on my back while holding two torches in each hand to chase away the elephants,” Yasmin said
we were all women protecting ourselves and herding the elephants back to the jungle.”
a Kelompok Meurah member and the only female community member of the government’s Conservation Response Unit (CRU)
said she and her team are always ready to deal with elephants entering the village
They walk around the village toward the elephants to herd them back out to the jungle
“We [the women] can’t just sit around in the house — we have to go out and help our friends herding the elephants,” Salamah said
the team usually stands its ground to watch over the crops so the elephants can’t enter the farms
They’re also ready to leave immediately to assist any family whose house is invaded by the elephants
“The recent case in Alue Buloh was when someone’s house was completely destroyed by an elephant
The elephant entered the house and rummaged in the fridge while the owners were away shopping for food in town,” she said
a professional mahout from the Conservation Response Unit
and was relocated to work with the CRU in Cot Girek since 2020
He said it’s their duty as mahouts to groom
The government has formed 13 CRUs across Aceh province with trained elephants such as Marni to assist them in herding wild elephants back to the jungle
Just like other captive elephants under the CRU’s care
Marni knows whenever wild elephants are on their way to the village
She raises her trunk to alert the residents of Cot Girek that the wild elephants are coming
The mahouts and the volunteer elephant patrol team work together with the captive elephants to deal with the wild elephants and herd them back into the jungle
“Elephants are intelligent; our elephants would follow us when we walk and come over when we call them,” Iwan said

a demon wreaked havoc on a monastery in Tibet
Guru Rinpoche chased it south to Upper Mustang in Nepal and defeated the demon following a ferocious battle

The people of Mustang honoured the sacred grounds by building monasteries atop the demon's body parts

"And right on the demon's heart, the capital of Lo Manthang [was built] in 1380," says Kunga, pointing towards the narrow alleys, ancient monasteries, and flat roofs adorned with prayer flags of one of the last medieval walled cities in the world
have thrived in this remote region situated on top of the Tibetan Plateau
One thing that has remained constant is the monasteries
Increased rainfall saturates the rammed-earth buildings
as moisture in the soil is drawn upward into the walls
leading to issues such as leaking roofs and rising damp

the paintings and the artifacts in the monasteries are embodiments of the gods themselves
and we can't worship a half-damaged idol," says Kanga
Buddhist monasteries have long been revered as the foundation of Tibetan culture
serving as a vital hub for the creation and safeguarding of both tangible artifacts and profound intellectual traditions
But as unprecedented weather patterns pose a threat to their cultural heritage
local community members have stepped up to restore them
from reinforcing walls to crafting metal statues and restoring paintings
a team of local Lobas trained by Western art conservationists have replaced the old
leaky roofs of the temples with round timbers
sculpted pillars and the ceiling decorations
giving these centuries-old monuments a new life
Luigi Fieni, the lead art conservator at Lo Manthang
Transforming a community of farmers into conservators has been challenging
Most of the Lobas had never held a pen or a paint brush before
and undertook extensive training before they began restoring the 15th Century paintings
"But it all worked out," says Fieni
"Tourists visiting Mustang were keenly interested in religion
So we felt these sacred artifacts needed preservation not only for their historical significance but also for sustaining livelihoods here."
although there was initial reluctance to accept any women in the group
women are prohibited from touching sacred objects
women did eventually take part in the Lo Manthang restoration project
"It took years of discussion and negotiation with the local clergy and community
but we succeeded in including local women in the wall-painting conservation team," says Fieni
Married Tibetan women are typically responsible for cooking
churning the butter and collecting yak dung for fuel
When she received the opportunity to pursue new training and earn a daily wage in the restoration project
"It enabled many of us [women] to break free from the limits of our homes
and find new opportunities," she says
confined to the corners with little purpose or prospects."
wasn't there just to learn art or refine her painting skills
She believed that by participating in the monastery's restoration
she would earn spiritual merit and contribute to the promotion of Tibetan Buddhism through her work
scraped-off outlines of deities and the vibrant expressions of revived figures
you will recognise the incredible scale of everyone's efforts
It has increased the cultural value of Lo Manthang," says Tsering

leading to widespread flood damage in neighbouring villages
The roads facilitating easy transport in the region have also contributed to rapid population decline
with many Lobas moving to cities in search of economic opportunities
Tashi Gurung stands out as a prime example of a farmer-turned-restorer who chose to remain in the region
He wasn't exposed to Tibetan Buddhist art as a child
but today he owns an art gallery in Lo Manthang
His gallery showcases a remarkable array of thangkas
and various deities and other spiritual beings such as the bodhisattvas
His art sales not only sustain himself but also enable him to send his children to school
Gurung acknowledges the profound impact of monasteries on his life
"If it weren't for the monasteries
I might have followed my friends who left Mustang for better opportunities abroad," he says
The restoration efforts have sparked a cultural renaissance
Numerous women and young people have received training in traditional craftsmanship
long-forgotten festivals have been revived
magnificent wall paintings restored for religious purposes
and monasteries and nunneries are thriving once again
"Om mani padme hum," the students at the Lo Monastic School chant the mantra that Tibetans use to invoke the bodhisattva of compassion
the danger imperilling the walled city of Lo Manthang and its age-old monasteries doesn't stem from mythological demons
but rather from the impacts of climate change
we all need to join hands and save the monasteries because everything here spins around religion," says Tsering

They translated Sanskrit texts and built monasteries
One of many projects taken on by Mustang’s last king—Jigme Dorje Palbar Bista
who abdicated by order of the Nepalese government in 2008—was to work with the American Himalayan Foundation in an effort to restore many of the damaged temples
which had fallen into disrepair over the last few centuries

Tibetan Buddhism is a Vajrayana lineage and includes four sub-schools–Nyingma
These sects have a lot in common with other Buddhist traditions and the broader Buddhist landscape
including the core beliefs of reincarnation
the principle of nonviolence against all living beings
the role of meditation as a means of reaching enlightenment
as well as the commitment to the Buddha’s Four Noble Truths
A key feature of Tibetan Buddhism—as well as other Mahayana Buddhist traditions—is reverence for bodhisattvas
spiritual practitioners who are close to achieving enlightenment but
delay its ultimate attainment to guide others along the path to Buddhahood
having extinguished the flame of their being
continue to be reborn for the benefit of all beings
Instead of devoting themselves to a single Buddha

the murals are not only historical artifacts but also objects of active worship—a duality that cannot and should not be ignored
Fieni draws up a similarly passionate defense

it is not a matter of who is right and wrong
but of accepting different choices because they relate to different cultures
Since there can never be a globalization of conservation

The mitochondrial calcium uniporter is a highly selective channel responsible for mitochondrial Ca2+ uptake
The mitochondrial calcium uniporter shapes cytosolic Ca2+ signals
Here using direct patch-clamp recording from the inner mitochondrial membrane
we compare mitochondrial calcium uniporter activity in mouse heart
heart mitochondria show a dramatically lower mitochondrial calcium uniporter current density than the other tissues studied
mitochondrial calcium uniporter activity is barely detectable compared with that in other fly tissues
As mitochondria occupy up to 40% of the cell volume in highly metabolically active heart and flight muscle
low mitochondrial calcium uniporter activity is likely essential to avoid cytosolic Ca2+ sink due to excessive mitochondrial Ca2+ uptake
low mitochondrial calcium uniporter activity may also prevent mitochondrial Ca2+ overload in such active tissues exposed to frequent cytosolic Ca2+ activity
heart mitochondria manifested the lowest MCU activity
The MCU current density in heart mitochondria was 30 times smaller than that in skeletal muscle
The relevance of this evidence was further corroborated by our observation that mitochondria from the highly metabolically active Drosophila flight muscle manifests almost no MCU activity
at variance with other populations of Drosophila mitochondria
which indeed possess large current densities
Our results are the first direct evidence that the amount of Ca2+ uptake mediated by the MCU varies between tissues
The low mitochondrial Ca2+ conductance observed in tissues with a high mitochondrial volume density and that are continuously subjected to high cytosolic Ca2+ elevations
such as mouse heart and Drosophila flight muscle
is likely to be essential in having normal intracellular Ca2+ signaling
as well as protecting these active tissues from toxic mitochondrial Ca2+ overload
the success rate in formation of the ‘whole-mitoplast’ mode of the patch-clamp technique to record currents across the whole native IMM was low
Here we patch-clamped mitoplasts derived from French-pressed mitochondria of mouse heart
The French press protocol used to obtain vescicles of the IMM proved instrumental in increasing the yield of reliable and stable whole-mitoplast recordings from all tissues studied
Whole-mitoplast current recorded before (black traces) and after (red traces) application of 100 μM Ca2+ to the bath solution
Currents were elicited by a voltage-ramp protocol (shown above) from different mouse tissues (as indicated)
Note that brown fat mitoplasts were isolated from mice deficient for uncoupling protein 1 (UCP1
Whole-mitoplast IMCU was normalized to the membrane capacitance (Cm) in all tissues examined
representative transmitted differential interference contrast image of a mouse heart mitoplast obtained with French press
Note the figure 8-shaped form of the mitoplast
The lobe of the mitoplast containing only the IMM was less dense (white arrow) and clearly distinguishable from the lobe covered with the OMM (red arrow)
Bottom right panel: Histogram showing average IMCU current densities in 100 μM Ca2+ in different tissues
Current amplitudes were measured at 5 ms after stepping from 0 mV to −160 mV (see the voltage protocol)
Note the low IMCU current density in heart compared with other tissues
Statistical data are represented as mean±s.e.m
(a) Left panel: representative whole-mitoplast current recorded from a mouse heart mitoplast before (black traces) and after (red traces) application of 150 mM Cl− to the bath solution
Currents were elicited by a voltage-ramp protocol (shown above)
The whole-mitoplast Cl− current was normalized to the membrane capacitance (Cm)
but the traces represent an average of 30–50 original current traces to smooth out fluctuations of the outward Cl- current mediated by the large-conductance inner membrane anion channel (b) Left panel: representative whole-mitoplast current recorded from a mouse skeletal muscle mitoplast before (black traces) and after (red traces) application of 150 mM Cl- to the bath solution
but the traces represent an average of 30–50 original current traces to smooth out fluctuations of the outward Cl- current mediated by the large-conductance anion channel
(c) Histogram comparing average Cl− current densities in 150 mM Cl− in mouse heart (n=4) and skeletal muscle (n=3)
Current amplitudes were measured at +80 mV (see the voltage protocol) and normalized to the Cm
As skeletal muscle and heart are related tissues and showed the higest and lowest IMCU current densities
we compared the biophysical properies of IMCU in these tissues to confirm that IMCU has the same properties in heart and skeletal muscle and is thus mediated by the same channel
(a) IMCU elicited by a voltage-step protocol (as indicated on top
ΔV=20 mV) in skeletal muscle (left panel) and heart (right panel)
(b) IMCU recorded in the presence of 100 μM Ca2+ (blue trace) was completely inhibited by 50 nM RuR (red trace) both in skeletal muscle (left panel) and heart (right panel)
The black traces indicate the baseline recorded in the absence of Ca2+ in the bath
Currents were normalized to the membrane capacitance to compare IMCU in heart and skeletal muscle
(a) Representative IMCU recorded in the presence of different concentrations of Ca2+ in the bath: nominal Ca2+-free (black)
Representative IMCU recorded from a skeletal muscle mitoplast in the presence of 100 μM Ca2+ (red trace)
Representative IMCU recorded from a heart mitoplast in the presence of 1 mM Ca2+ (red trace)
(c) Histograms of the relative permeability of IMCU to Ca2+
Current amplitudes were measured at 5 ms after stepping from 0 to −160 mV (see the voltage protocol in b)
This finding identifies the MCU as the Ca2+ channel with the highest known Ca2+ selectivity
asked whether the MCU in mouse heart and skeletal muscle has the same high selectivity for Ca2+ over monovalent ions as the MCU in COS7 cells
(a) Na+ current through the MCU under DVF conditions (black trace)
and in the presence of either 11 nM (red trace) or 160 nM (blue trace) free Ca2+ in the bath solution
Currents were normalized to membrane capacitance
The voltage protocol is shown in bottom of the figure
(b) The Na+ current through the MCU before (black trace) and after (red trace) the addition of 200 nM RuR to the bath solution
(c) Monovalent current through the MCU in symmetrical 110 mM Na+ (black trace) and after replacement of bath Na+ with K+ (red trace)
(d) Histogram showing average densities of Na+ current through the MCU in skeletal muscle (n=5) and heart (n=5)
Current amplitudes were measured at 5 ms after stepping the membrane from 0 to −160 mV (see the voltage protocol)
Thus IMCU in heart and skeletal muscle is likely mediated by the same molecule
but heart mitochondria are endowed with dramatically lower MCU activity
Although it has never been previously suggested
one of the specific reasons for this may be a higher Ca2+ conductance of the IMM in neonatal cardiomyocytes as compared with adult cells
Representative IMCU elicited in the presence of 100 μM Ca2+ (red traces) in a cardiac mitoplast isolated from a 2-day-old mouse
The black trace indicates the baseline recorded in the absence of Ca2+ in the bath
the same experiment performed with a cardiac mitoplast isolated from a 4-week-old (adult) mouse
Currents were elicited by a voltage-ramp protocol shown above
Whole-mitoplast IMCU was normalized to the Cm
(b) Histogram comparing average IMCU current densities in 2-day-old (n=5) and adult heart (n=8)
Current amplitudes were measured at 5 ms after stepping from 0 to −160 mV (see the voltage protocol) and normalized to the Cm
we found a dramatic difference in the density of the mitochondrial Ca2+ current among Drosophila tissues
(b) Left panel: Representative mitochondrial Ca2+ current recorded from a Drosophila flight muscle mitoplast in different concentrations of bath Ca2+: 5 mM (green)
Right panel: Representative mitochondrial Ca2+ current recorded from a Drosophila not flight muscle mitoplast in the presence of different concentrations of Ca2+ in the bath: 1 mM (red) and 100 μM (blue)
(c) Left panel: Histogram comparing average densities of Drosophila mitochondrial Ca2+ current at 100 μM in flight muscle (n=8) and not flight muscle tissues (n=3)
Right panel: Histogram comparing average densities of Drosophila mitochondrial Ca2+ current at 1 mM in flight muscle (n=21) and not flight muscle tissues (n=6)
In spite of the fact that the amplitude of the Ca2+ current was extremely low in flight muscle mitoplasts, these mitoplasts had very large Cl− current (Fig. 8) with the mean current density of 161±6 pA/pF at +80 mV, n=4. This is the first observation of the existence of a mitochondrial Cl− conductance in Drosophila.
Left panel: representative whole-mitoplast current recorded from Drosophila flight muscle before (black traces) and after (red traces) application of 150 mM Cl− to the bath solution
Right panel: Same experiment as in left panel
but the traces represent an average of 10–20 original current traces to smooth out fluctuations of the outward Cl− current mediated by a large-conductance channel
This uptake and the RuR-sensitive Ca2+ currents recorded from Drosophila mitoplasts are both likely to be mediated by a Drosophila homologue of the mammalian MCU
the present consensus in the field is that all mammalian mitochondria are endowed with approximately the same MCU activity and the same high ability to accumulate Ca2+
this allowed direct studies of MCU activity under highly controlled conditions
such as exact potential across the IMM and exact concentrations for all ions on both sides of the IMM
the patch-clamp technique allows for the dissection of single mechanisms involved in mitochondrial Ca2+ transport and allows the characterization of MCU activity at the single organelle level
limiting MCU activity in this tissue might not be necessary
It must be noted that although singular heart mitochondria have a limited ability to uptake Ca2+
their abundance can result in combined Ca2+ accumulation comparable to other tissues
it is not surprising that the MCU current density in Drosophila flight muscle is about four times lower than that in mouse heart
some mitoplasts originating from Drosophila tissues other than flight muscle have very high MCU current density
even exceeding the maximal MCU current density found in mice
MCU activity varies dramatically between tissues
Whether variations in MCU activity are due to tissue-specific regulation of the MCU (for example
via auxiliary subunits) or to different tissue-specific expression of the MCU channel requires further investigation
the tight control of MCU activity in highly active cells with intensive cytosolic Ca2+ signalling is likely crucial for the normal physiology of these cells and for the integrity of their mitochondria
Misregulation of MCU activity in such tissues may lead to derangement of intracellular Ca2+ signalling and mitochondrial dysfunction
followed by functional incompetence and degeneration
and adult flies >5 days of age after eclosion were used
Mouse or Drosophila mitoplasts (2–6 μm in size) were used for patch-clamp experiments and typically had membrane capacitances of 0.3–1.3 pF
Currents were recorded using an Axopatch 200B amplifier (Molecular Devices)
The voltage protocols and recording conditions are as indicated in the figures
To minimize errors in the voltage clamp associated with the liquid junction potential
a 3-M KCl-agar salt bridge was used as the bath reference electrode
Gigaohm seals with mitoplasts were formed in the bath solution containing 150 mM KCl
Capacitative transients were completely compensated right after the seal was formed
Voltage steps of 350–500 mV from 15–50 ms were applied to rupture the IMM and obtain the whole-mitoplast configuration
as monitored by the appearance of capacitance transients and an increase in baseline noise
The access resistance and membrane capacitance of mitoplasts were determined using the Membrane Test tool of pClamp 10 (Molecular Devices)
The averaged membrane capacitance of mitoplasts used in our experiments varied between tissues and was (0.65±0.04 pF
The calculated voltage clamp errors associated with the access resistance never exceeded 10 mV
Current amplitudes for histograms were measured within 5 ms after stepping the membrane from 0 to −160 mV
Bath solutions containing 100 μM–1 mM Ba2+ or Mg2+ were obtained by the addition of a 1-M stock solution of the corresponding chloride salt into the HEPES-Tris solution without EGTA
the following bath solution was employed: 110 mM K-gluconate
tonicity adjusted to 300 mmol per kg with sucrose)
All electrophysiological experiments were performed under continuous perfusion of the bath solution
Data acquisition and analyses were performed using PClamp 10 (Molecular Devices) and Origin 7.5 (OriginLab)
All electrophysiological data presented were acquired at 10 kHz and filtered at 1 kHz
Statistical data are presented as the mean±s.e

where he dedicates a significant portion of his days examining schistosomiasis
can carry a parasitic worm causing snail fever
Schistosomiasis stems from a parasitic worm called Schistosoma japonicum
The snails carrying these worms are found exclusively in 28 villages in Central Sulawesi
specifically in Poso (Bada and Napu highlands) and Sigi districts (Lindu highland)
Snail fever poses a persistent threat to the health of the 22 000 individuals residing in Poso and Sigi Districts
Indonesia is the last country in the South-East Asia Region working towards eliminating schistosomiasis as a public health issue
the 54-year-old Napu native with over three decades of experience in schistosomiasis
reflects on the enduring impact of this parasitic disease on the local community as he pockets the snails and rides his trusty motorcycle back to the laboratory in Wuasa village
The village's livelihood has been at risk for years
prompting community-based measures such as reworking the land
Cerni quickly geared up in his lab suit before placing the snail samples under the microscope
sprays the host snail areas twice a year with niclosamide to eliminate snails
The focus areas are surrounded by water seepage and long grass
requiring thorough cleaning and trimming before spraying
Cerni also works with the community to support screening and treatment
\"There are instances where no one shows up when we go to collect stool samples
Achieving the 80% target typically requires about a month in each village,\" he noted
Cerni suspects that people's reluctance to be tested or undergo treatments is often influenced by weariness
He shared the story of an individual who never received a positive schistosomiasis result in ten years and grew bored of the annual test
find the treatments and test routines helpful and approach them with a positive attitude
the mass drug administration (MDA) programme has consistently been received in a good light by the community – everyone

I can't say that I’m tired of these routines.\" Underscoring his dedication to eliminating schistosomiasis
he emphasized the critical role of all members of the village to address this issue collectively
WHO works with communities such as Cerni’s
to move Indonesia closer to the goal of eliminating schistosomiasis once and for all.
The five-hectare land is one of the snail host focus areas
several farmers have grouped together to transform the patch into productive ponds
The combined efforts of the community bring about agricultural opportunities while protecting the village against snails

a young farmer from Leubok Pusaka village in North Aceh district
was on his way to his plantation when he spotted eight elephants on the riverbank
One seemed to be staring at Saleh’s moving canoe
Elephants!” Saleh and his friends shouted until all the animals were gone behind the trees
a district near the northern tip of Indonesia’s Sumatra Island
They couldn’t cross the river and they couldn’t return to the forest due to land-clearing activities in the opposite direction
the herd finally managed to escape during a downpour
the elephants found food in the villagers’ farms and destroyed four houses
there’s been massive land clearing in North Aceh
which lies along Sumatra’s eastern coast in the province of Aceh
Despite the district’s enforcement of a moratorium on issuing new permits for corporate oil palm plantations
conservationists report ongoing deforestation on the ground
The North Aceh government has granted permissions for land clearing for smallholder oil palm farms
some of which are said to be controlled by powerful people in the region
has further fragmented the habitat of Sumatran elephants
I believe the animals will soon go extinct,” Nurdin said
doing their best to survive in the fast-changing environment
“More than 85% of Sumatran elephants live outside conservation areas,” Azmi said
there are four to five human-elephant conflicts reported every day
conflict intensity escalated in North Aceh
where much of the land has been cleared for oil palm
a loud bang from a PVC air cannon woke Junaidi at 2 a.m
The 41-year-old farmer heads the village’s elephant patrol team
he knew it was a sign that wild elephants were moving in
“Shoot the canon five times if you find wild elephants around your house” — that’s how the villagers have been told to communicate with others who might live kilometers away with poor cellular service
but as patrol leader he had to get up and investigate despite the rain
he walked some 10 kilometers (6 miles) along muddy roads around the village to check the situation
Junaidi and other villagers in Cot Girek and Leubok Pusaka have been staying awake at night
four wooden huts were reportedly destroyed by elephants
a smallholder oil palm farmer who lives 3 km (nearly 2 mi) from Junaidi’s hut
was shocked to see 400 oil palm shoots in his plantation chewed up by elephants
who didn’t want her crops to meet the same fate
an environmental activist from a local NGO called People’s Conscience
said the increasing cases of human-elephant conflict are caused by habitat loss
Cleared land can be seen from Junaidi’s hut
Deforestation has eliminated the transition zone between the hills and the village
“Elephants are coming from that hill,” Junaidi said
pointing to a forested area over the horizon
the geographical information system manager at Forest
a conservation group focused on Sumatra’s Leuser Ecosystem
North Aceh has long had one of the highest deforestation rates in Aceh province
His analysis of satellite data generated by Planetscope
which he called the most accurate satellite image provider
shows the district lost 7,508 hectares (18,553 acres) of forest from 2017-2020
Satellite data generated from forest monitoring platform Nusantara Atlas show significant deforestation in Leubok Pusaka and Cot Girek
said data he had collected from GPS collars tagged to elephants in North Aceh from 2016-19 showed that rainforest had been cleared within the elephants’ migration routes
acknowledged land-clearing activities in Cot Girek
“But these lands are classified as non-forest,” she said
Lilis also said most of this clearing was done by local people rather than corporate actors
the district has actively applied a freeze on new oil palm permits
“We no longer give permit for companies to open up new oil palm plantations,” she said
“Nor do we give oil palm seeds to smallholder farmers.”
is the political extension of the movement
It has always been poor villagers and elephants who suffer from conflict
Junaidi’s hut sits between the forest and oil palm plantations owned by state-owned PT Perkebunan Nusantara I
Junaidi said the company relies on the villagers’ patrol team to mitigate elephant conflicts
“We are guarding their gate … all information about wild elephant movement comes from us,” he said
(PTPN I did not respond to an interview request.)
People like Junaidi and Saleh Kadri have to rely on their own resources to herd the elephants away from their village
“We have reported about elephant conflicts in our village so many times but there has been no response from the government,” Saleh said
We are tired of this … We hope the government can help farmers like us.”
the elephants managed to leave the village
They were last seen heading to Paya Bakung
a subdistrict of North Aceh where a huge infrastructure project is being constructed
To mitigate the annual flooding in Lhoksukon
authorities are building the Kreung Keureto reservoir in Paya Bakung
They will have to come back to … Cot Girek and finally Langkahan
where they can’t cross the river and start their journey all over again,” Nurdin said
“Poor elephants … they are chased from every side,” he added

The principle guiding this roadmap is the understanding that the best available research evidence should be at the centre of the COVID-19 response and underscores the need to strengthen Indonesia’s health research system.
Rapid review dissemination from UGM CHPM-Cochrane on Incident Command System (under Pillar I: Country‑level coordination
sourcing from national databases such as Garuda (Garba Rujukan Digital) and SINTA (Science and Technology Index)
increase access to research articles and more effectively communicate findings to policymakers
WHO and MoH along with other stakeholders joined together to cultivate an ecosystem that facilitates the utilization of evidence in the country
One of the initiatives involved collaboration with experts from research institutions mandated to support COVID-19 response and preparedness at national and subnational level.
WHO Indonesia engaged over 20 experts from four institutions in capacity-building activities
This initiative involved establishing a network of experts
centred around synthesizing research evidence using rapid review methodologies and packaging the findings for effective use by policymakers.
Dr Bayu Dhite from UGM CHPM - Cochrane presenting rapid review findings on Incident Command System
Aufia Espressivo from CISDI presented rapid review findings on community-based surveillance
Each institution identified real-life public health and health system policy topics related to COVID-19 response and preparedness in terms of the structure
organization and functions of the health system; actions and practices of stakeholders within the health system; or conditions and factors related to implementing certain changes
Key insights from their research include:
Implementation of the Incident Command System (ICS): Highlighted the importance of ICS in managing health emergencies such as COVID-19
Strengthening non-communicable disease (NCD) health services: Strategic use of technology in NCD service delivery would enhance primary healthcare
requiring increased investment in health information and digital skills.
Digital health surveillance: Identified the need for a technology innovation hub and matchmaking forum for developers and users.
Community-based surveillance (CBS): Leveraging Indonesia’s CBS system for tackling airborne diseases
I Nyoman Sutarsa from School of Public Health Udayana presenting the effect of pandemic on NCD services through online platform
The findings from the rapid reviews were deliberated during the 8th COVID-19 response intra action review (IAR) monitoring meeting held from 21-24 June 2023 in Jakarta
These findings enriched and bolstered the discussions during the IAR meeting
leveraging the lessons learned captured in the research evidence along the various COVID-19 response and preparedness pillars
The network of experts will continue to provide support so that research evidence can be used more efficiently and effectively for enhanced evidence-based policymaking
WHO will support Indonesia with development and establishment of a research council and accelerate the establishment of research databases to improve use of evidence
These next steps will enhance Indonesia’s COVID-19 response and will lay the groundwork for a more resilient health system in Indonesia.
On a humid and rainy afternoon in Demak District
Central Java health professional Dr Lisa Novipuspitasari looks out from her clinic and recalls the number of times that floods swallowed roads
The coastal community she serves is familiar with the ferocity of water
Heavy rains coupled with rising tides and coastal erosion make the area prone not just to flooding but the diseases it brings
“Today I attended to another suspected leptospirosis patient in the emergency unit,” she shares with concern
we escalated another case from observation in emergency care to inpatient treatment,” she adds
Dr Lisa has been at the forefront of the fight against leptospirosis
a zoonotic and climate-sensitive disease that can result in mild illness that may progress to a serious and sometimes fatal disease
She is one of just a few leptospirosis specialists in Demak
treating patients with symptoms ranging from flu-like illness to kidney failure and Severe Pulmonary Hemorrhagic Syndrome
Dr Lisa standing in front of the RSUD Sultanfatah sign
As one of just a few leptospirosis specialists
she is leading efforts to prevent and control leptospirosis infections
Leptospirosis barely registered as a concern
even among health professionals,” she explains
and with insights obtained from research by the National Research and Innovation Agency
leptospirosis is misdiagnosed as dengue or typhoid
leading to tragic outcomes when diagnosed and treated too late,” she says ruefully
the Food and Agriculture Organization of the United Nations (FAO)
USAID-IDDS and the Indonesian Ministry of Health and local government have joined forces to strengthen leptospirosis prevention and control in Demak
which is expected to face rising sea levels and land subsidence of two to eight centimeters per year

to the collective efforts of partners and the community to protect health and well-being from infectious diseases and the health impacts of climate change.
A type of meteorite called an enstatite chondrite has similar isotopic composition to terrestrial rocks and thus may be representative of the material that formed Earth. A new study published in the journal Science shows that these meteorites contain sufficient hydrogen to have delivered to Earth at least three times the mass of water in its oceans

Enstatite chondrites are space rocks forged from the nebula that formed the Solar System
They are rare, making up only about 2% of known meteorites in collections
But their isotopic similarity to terrestrial rocks make them particularly compelling
and the new study showed that their hydrogen and nitrogen isotopes are similar to Earth’s
“Our discovery shows that the Earth’s building blocks might have significantly contributed to the Earth’s water,” said Dr. Laurette Piani
a researcher at the Université de Lorraine
“Hydrogen-bearing material was present in the inner Solar System at the time of the rocky planet formation
even though the temperatures were too high for water to condense.”
The building blocks of Earth are often presumed to be dry
They come from inner zones of the Solar System where temperatures would have been too high for water to condense and come together with other solids during planet formation
The meteorites provide a clue that water didn’t have to come from far away
“The most interesting part of the discovery for me is that enstatite chondrites, which were believed to be almost dry, contain an unexpectedly high abundance of water,” said Dr. Lionel Vacher
a postdoctoral researcher at Washington University in St
“If enstatite chondrites were effectively the building blocks of our planet — as strongly suggested by their similar isotopic compositions — this result implies that these types of chondrites supplied enough water to Earth to explain the origin of Earth’s water
The team also proposes that a large amount of the atmospheric nitrogen — the most abundant component of the Earth’s atmosphere — could have come from the enstatite chondrites
“Only a few pristine enstatite chondrites exist: ones that were not altered on their asteroid nor on Earth,” Dr
we have carefully selected the enstatite chondrite meteorites and applied a special analytical procedure to avoid being biased by the input of terrestrial water.”
Coupling conventional mass spectrometry and secondary ion mass spectrometry allowed the scientists to precisely measure the content and composition of the small amounts of water in the meteorites
it was commonly assumed that enstatite chondrites formed close to the Sun,” Dr
“These chondrites were thus commonly considered dry
and this frequently reasserted assumption has probably prevented any exhaustive analyses to be done for hydrogen.”

Maryna Viazovska’s work on packing spheres and James Maynard’s solving of prime number conundrum honoured in Helsinki
A Ukrainian mathematician who proved the best way to pack spheres in eight dimensions to take up the least space
and an Oxford expert who has solved conundrums in the spacing of prime numbers
considered the equivalent of a Nobel prize for mathematics
presented at the International Mathematical Union awards ceremony in Helsinki
have been announced as Prof James Maynard 35
of the École polytechnique fédérale de Lausanne
of the University of Geneva and Institut des Hautes Études Scientifiques
While the first Fields medal was awarded in 1936
since when it has been presented every four years to up to four mathematicians who are under 40
Viazovska, who was born and grew up in Kyiv, is only the second woman to receive the award, after the win by Iranian mathematician Maryam Mirzakhani who became a medalist in 2014

Maynard – who is expecting the birth of his baby imminently – said he learned of his win while up a ladder tackling house renovations
“I was grabbing my phone to use it as a torch to help to see if I had messed the painting up or not
And I noticed that had I got a email then from the IMU president asking to have a zoom call,” he said
Maynard’s citation points to his “spectacular contributions in analytic number theory” – among them his work on the distribution of prime numbers
“Prime numbers are like the atoms for mathematicians,” said Maynard
“In the same way that you can understand an awful lot about chemicals by knowing the atoms that make them up
you can understand the huge amount about whole numbers and how they interact with multiplication – which turns out to be very important for things like cryptography – if you understand things about prime numbers.”

Photograph: Matteo FieniA key step in trying to understand prime numbers
is to look at the size of the gaps between them
Maynard has made a number of breakthroughs
including showing that sometimes prime numbers come unusually close together and sometimes unusually far apart
said that when Maynard made an early pivotal discovery in how often pairs of prime numbers occur that are two steps apart – such as three and five – Graville told the young mathematician he must have made a mistake
he’s not a one horse wonder … James has approached one [question] after another and just made massive headway.”
Granville also praised the work of Viazovska
who solved the problem of the densest way to pack spheres in eight dimensions and
and relied on tens of thousands of lines of computer code
Viazovska, said Granville, took the question even further, finding the solution in higher dimensions. “It turns out that in dimensions eight and 24, the solution is much easier than our common dimension, three,” Viazovska said in 2018
professor of mathematics at Princeton and also at the Institute for Advanced Study in Princeton
“Viazovska invents fresh and unexpected tools that allow her to jump over natural barriers that have held us back for years,” he said
involves the mathematical theory of phase transitions – for example when ice melts to liquid water – in statistical physics
According Plus Magazine, Huh was more interested in poetry than maths at school, but became hooked on maths after attending lectures by Heisuke Hironaka
Huh and colleague Petter Brändén found a connection between mathematical models for optimising situations involving variables that are related in a continuous way
and those where the relationships are discrete
“Finding this formal bridge was very satisfying.” Huh told the magazine
“And what was even more pleasant for us is that once you have this bridge you can approach problems that were considered very technical and difficult in a very natural and easy way.”

The newborn immune system is characterized by an impaired Th1-associated immune response
Hepatitis B virus (HBV) transmitted from infected mothers to newborns is thought to exploit the newborns’ immune system immaturity by inducing a state of immune tolerance that facilitates HBV persistence
we demonstrate here that HBV exposure in utero triggers a state of trained immunity
characterized by innate immune cell maturation and Th1 development
which in turn enhances the ability of cord blood immune cells to respond to bacterial infection in vitro
These training effects are associated with an alteration of the cytokine environment characterized by low IL-10 and
Our data uncover a potentially symbiotic relationship between HBV and its natural host
and highlight the plasticity of the fetal immune system following viral exposure in utero
To directly characterize the impact of HBV exposure on the newborn immune system
we performed a comprehensive immunological analysis of the cord blood (CB) cells from neonates of HBV chronically infected mothers
We report that HBV exposure in utero does not induce generic immunological defects but
is associated with a mature immunological profile that enhances the ability of the neonatal immune cells to respond to unrelated pathogens in vitro
(a) CB plasma cytokines were determined by multiplex assay in seven healthy controls and ten HBV+ mothers
(b) Ratio of Th1/Th2 cytokine (IL-12p70/IL-10) in healthy and HBV-exposed CB
P-values were calculated using Mann–Whitney test
The frequency of total APCs (or HLA-DR+ cells) and of the various APC subsets was not affected by HBV exposure in utero
(c) The mRNA expression (in Nanostring counts) of the chemokine CXCL13 in monocytes measured with Nanostring technology
(d) Sorted CD14+ monocytes from healthy (n=4) and HBV-exposed (n=3) CB were incubated with 1 μg ml−1 ssRNA40 (TLR8 agonist) for 18 h and IL-12p40 in the supernatant measured using luminex
(e) The median fluorescence intensity (MFI) expression of HLA-DR
CD40 and CD80/CD86 on CD14+ monocytes from healthy (n=5) and HBV-exposed (n=10) CB
(f) Sorted CD14+ monocytes from healthy (n=7) or HBV-exposed (n=8) CB were incubated with allogeneic CFSE-labelled CD3+T cells (E:T ratio 1) for 7 days and CFSE staining analysed using flow cytometry
T-cell proliferation index was calculated using Flowjo
Horizontal line in dot plots represents the median
P-values in c–f were calculated using Mann–Whitney test
Newborn T cells produce IL-8 but are defective in Th1 cytokine production11
As IL-12p40 has been shown to increase IFN-γ production in adult T cells
we analysed the ability of CB T cells to produce Th1 and other important T-cell cytokines (that is
(a) CB mononuclear cells were stimulated overnight with phorbol myristate acetate (PMA)/ionomycin and the cytokine production by CD3+T cells was measured using intracellular cytokine staining
Dot plots show the percentages of cytokine-producing CD3+T cells from healthy (HC; n=6) or HBV-exposed (HBV; n=11) CB
Cytokine production by CD3+T cells from the peripheral blood of pediatric and young adult patients with chronic HBV (HBV; n=10) and age-matched healthy controls (HC; n=33) were included for comparison
(b) Representative FACS dot plots of Th1 cytokine (TNF-α
IFN-γ and IL-2) production from healthy and HBV-exposed CB T cells after PMA/ionomycin stimulation
double- and triple-producer Th1 cells and their respective percentages in mean±s.e.m
(d) Percentage of T cells expressing the Th1 marker
in CB of healthy (n=4) and HBV+ (n=4) mothers
P-values were calculated using Mann–Whitney test.*P<0.05
We next analysed whether the enhanced immune maturation detected in HBV-exposed CB could result in a better ability of the neonatal immune cells to respond to unrelated pathogens
CB mononuclear cells from healthy (n=3) or HBV+ (n=3) mothers were incubated with the bacteria P
monocytogenes (multiplicity of infection (MOI) 1) for 18 h and the cytokine production in the supernatant was analysed using multiplex assay
P-values were calculated using two-way analysis of variance and multiple comparisons were done using uncorrected Fisher’s least significant difference test
(a) FISH analysis with X- and Y-chromosome-specific probes to detect maternal cells in male CB
Graphs show the percentages of maternal cells (mean±s.e.m.) in CB unfractionated and fractionated cells (n=2 per group)
Statistical significance between groups was calculated using Mann–Whitney test
P-value <0.05 is considered statistically significant
(b) Representative FISH images from each sorted cell population in healthy and HBV-exposed CB
Nuclei were counterstained with DAPI (blue)
Maternal cells (white arrow) contain green chromosome X signals and no Y signals
(c) Quantitative PCR analysis using 48:48 Dynamic Arrays (Biomark System-Fluidigm) of CD14+ single cells derived from HBV-exposed CB of male neonate
Two male (M)-specific genes (XKRY and TTY1) are expressed in CB cells and not in female (F) cells
XIST gene is selectively expressed in female cells
These results demonstrate that the immunological changes observed in HBV-exposed CB is unlikely to be due to an increase in maternal cell contamination
but probably due to genuine maturation of the neonatal immune cells
despite the latter being tested positive for HBV-DNA in the CB plasma
(a) CD2− cells were enriched from CB using MACS beads and the presence of HBsAg was detected using immunofluorescent staining
Detection of HBsAg in CB cells (white arrow) from healthy and HBV+ mothers (green–HBsAg; blue–DAPI)
Images are representative of seven CB samples per group
CB cells incubated with recombinant HBsAg was used as positive control
(b) Percentage of HBsAg+ cells among DAPI+ cells in healthy and HBV-exposed CB (n=7 per group)
P-value was calculated using Mann–Whitney test
the presence of HBsAg+ cells in the CB of neonates of HBV+ mothers indicates that their immune system has been in contact with the virus or viral products before birth
The low frequency of HBsAg+ immune cells detected in the CB of HBV-exposed neonates suggests that it is unlikely that HBV antigens can directly cause the maturation of monocytes in HBV-exposed CB
We hypothesize that the altered cytokine environment detected in the CB plasma of HBV-exposed neonates could be responsible for the induction of monocyte/T-cell maturation
CB mononuclear cells from healthy mothers (n=3) were incubated with rhIL-12p40 or rhIFN-α2
either alone or in different combinations of concentrations
overnight and the activation phenotypes of T cells and monocytes were analysed by FACS
Graphs (a,b) show the data from one representative sample
Dotted lines indicate the basal level without any cytokine stimulation
(a) The percentage of T-bet+ cells in CD4+ and CD8+ CB T cells
(b) The median fluorescence intensity (MFI) of expression of HLA-DR
(c) The activation phenotypes of T cells and monocytes in CB cells (n=2
denoted 1 and 2) stimulated with physiological concentrations of rhIL-12p40 (0.1 ng ml−1) and rhIFN-α2 (0.4 ng ml−1)
no such evidence has been demonstrated so far in newborns during the course of a natural viral infection
we demonstrated that HBV exposure in utero induces a state of trained immunity characterized by enhanced innate immune cell maturation and increased Th1 development
this immune system maturation results in a better ability of the neonatal immune cells to respond to unrelated pathogen exposure
the infant’s immune system does not only acquire a more pronounced Th1 T-cell profile but also decrease its ability to produce IL-10 and pro-inflammatory cytokines
A further alteration induced by HBV exposure was the detection of higher levels of IFN-α2 that were only statistically significant in the CB plasma of Asian but not Caucasian HBV+ mothers
Whether such differences could be explained by different HBV genotypes infecting the two cohorts (HBV genotypes B/C in Asian patients versus HBV genotype D in Caucasian patients) will require further analysis
where virus-specific T cells can be detected in neonates
A possible scenario is that HBV has evolved a special relationship with its human host: although the defective priming of HBV-specific T cells can predispose to HBV chronicity
the induction of a trained immunity profile with a skewed Th1 response and suppression of pro-inflammatory events might have the advantage of decreasing mortality from exposure to unrelated pathogens
but certainly a more precise evaluation of the immunological events that are occurring in the early phases of HBV infection is needed
might actually be the source of IL-12p40 production in response to HBV
Pregnancy is known to modulate the natural history of HBV infection
but whether placental cells can actually play a direct role in the modulation of maternal or neonatal infections remains unknown
All mothers in the HBV group were positive for HBsAg and negative for human immunodeficiency virus

Team Lead (NCD and Healthier Populations) WHO Indonesia
presented fact sheets on the WHO-supported study on trans-fatty acids to Prof
Vice Minister of Health of the Republic of Indonesia
This moment marks the official launch of the results of the study
The World Health Organization (WHO) has published the results from a ground-breaking study on the dietary sources of trans-fatty acids in Indonesia’s food supply
This launch aims to support the issuance of government regulations to eliminate trans fats
Trans fats or trans fatty acids are unsaturated fatty acids that come from natural or industrial sources
Consumption of trans fats can significantly increase the risk of heart attacks and contributes to an estimated 500 000 deaths from coronary heart disease globally each year
The baseline study involved laboratory testing of 130 products across four food categories: oils and fats
packaged foods made with fats (such as biscuits
cakes and bread) and prepared foods such as fried noodles
WHO recommends trans fat levels in food of less than 2 grams per 100 grams of total fat
almost 10% of the products surveyed or around 11 foods contained trans fat levels exceeding these recommendations
High levels of trans fats are also found in popular and widely consumed snack products
bakery products and street snacks such as martabak
The highest concentration of trans fats is found in a mixture of margarine and butter
which is 10 times higher than the WHO recommended limit
it must be acknowledged that there is still a lack of data regarding trans fats in food
The Ministry of Health really appreciates the efforts of WHO Indonesia to conduct a study of trans fat content in food,\" said the Vice Minister of Health of the Republic of Indonesia
Dante Saksono Harbuwono at a high-level event in Jakarta
The Vice Minister of Health Dante said that the most effective way to reduce trans fats in the food supply is through regulation
WHO also encourages countries to adopt one of two best practice policies for eliminating trans fats
The first step is to limit trans fat levels to 2% of the total fat content in all foods
in 2018 WHO launched the global trans fat elimination initiative
which calls on countries to eliminate trans fats globally by 2023
The REPLACE framework consists of six strategies: first
reviewing trans fat dietary sources and policy landscape; second
encouraging the replacement of trans fats with healthier fats and oils; third
enact regulations to eliminate trans fats; fourth
assessing and monitoring trans fat content in the food supply; fifth
53 WHO Member States have adopted best practice policies for eliminating trans fats
including Denmark which became the first country to implement this policy since 2003
\"Denmark is the first country to ban trans fats in the food industry and this has been done since 2003
This can be done because before this ban their death rate from heart disease was very high,\" said the Vice Minister of Health
Ten years after the regulation was implemented
the death rate from heart and blood vessel disease fell by 20 percent
The Vice Minister of Health Dante emphasized that the Government of Indonesia is also fully committed to implementing regulations prohibiting the use of trans fats in the food industry in Indonesia
The Vice Minister of Health also assessed that limiting trans fats would reduce heart disease while saving Indonesia trillions of rupiah
He hopes that the preparation of regulations involving multiple sectors can make Indonesia the next country to implement regulations according to good practices recommended by WHO
“We will formulate these regulations in Indonesia
people will be healthier so that the death rate due to heart and cardiovascular disease will decrease,\" said the Vice Minister of Health
The Vice Minister of Health explained that the implementation of trans fat regulations would be accompanied by massive education
especially in the informal sector such as small and medium traders
53 WHO Member States globally have adopted best-practice trans fat policies
and WHO is working closely with the Government of Indonesia to ensure it becomes the next,” said WHO Representative to Indonesia
“The release today of WHO’s baseline study marks an important step forward in improving the food environment for more than 275 million Indonesians
enabling them to live longer and healthier lives,” he continued
The Ministry of Health of Indonesia is dedicated to safeguarding the health and well-being of its citizens
ensuring access to quality healthcare services
Through collaborative efforts with stakeholders and communities nationwide
the ministry strives to enhance healthcare infrastructure
ultimately improving the overall health outcomes for all Indonesians

The local government provides support in responding to the polio outbreak by conducting cross-sectoral socialisation in the district and cross-OPD (Organisasi Perangkat Daerah/Regional Government Organisation) to support Puskesmas in implementing the SUB PIN Polio programme
Various corporate social responsibility (CSR) programmes also help with additional food and gifts for children who receive vaccines

we will wait until they recover before vaccinating them during the sweeping activity," Dr

offers some insights into his icon of bank
I have lived in Lugano for the past forty years
but the only public commission the city has ever entrusted to me was a bus stop,” Mario Botta humorously confesses
This is despite the fact that this native of Switzerland
is the first Swiss architect of international renown since Le Corbusier
it’s no surprise that he describes Switzerland as both “a mother and a wicked stepmother.” He has built cathedrals
yet his hometown has only ever commissioned him for a bus stop
While Milanese writer Luca Doninelli called that very original creation—with lighting that changes according to the season—“the new cathedral of Lugano”
counterbalancing in a way the architect’s bulkier private commissions in the Swiss canton of Ticino
the bid he won in the early 1980s for the Banca del Gottardo in Lugano
the architect would erect what he called a “mature structure,” his first major urban work
located in Switzerland’s third largest financial center
It has since become an international icon of bank architecture
On the site of the bank had previously stood three turn-of-the-century villas and a parking garage
all buildings familiar to Botta since his childhood
tearing them down would not ultimately result in the destruction of his childhood memories
“I didn’t want to do what most people were proposing
We divided the site into four smaller buildings offset from each other by empty space to give it a dynamic look from the street
a face that symbolizes the stratified memory of the city built up over time
it’s rooted in the layering of history.” These words reflect the seminal influence of Louis Kahn
one of Botta’s heroes and a former collaborator in Venice at the very beginning of Botta’s career
The bank’s four facades are a take on the castle towers one finds in the nearby city of Como and
the building’s Mediterranean grandeur earned it the nickname “Palazzo Botta.” Its precious architectural poetry derives from its two shades of natural stone
a flourish that was anathema to bank architecture at the time with its rationally designed buildings and impersonal—empty—glass facades
“The glass-and-metal banks of the ‘70s and ‘80s
as today we only see them as buildings from the ‘70s without any identity of their own
banks from the beginning of the century are archetypal Greek Doric temples and call to mind historical monuments.” Perhaps the most vividly iconic example of this style is to be found on Wall Street and in the Financial District of New York City
Banking helped define Botta’s generation and it deserves a new interpretation: gone are the days of anonymous offices bustling with employees; rather
banks should stand out boldly in the urban landscape
Botta goes even further in his definition of the true identity of a bank: “We thought banks had to have sex appeal.” Though now owned by EFG International
the bank is Switzerland’s fifth-largest private bank
and the interior still exudes Botta’s great ambition
The sacred aura of the place is undeniable
which is no wonder since the architect has built iconic chapels through the Ticino region
Yet he refrains from drawing a hasty parallel between banking and religion
It’s a way to gild surfaces and truly generate space.”
"We are the very first press outlet to be given permission to photograph it
This is twenty-seven meters below lake level”
works of art are not in the bank’s vaults but on its walls
It is a kind of Guggenheim of the Swiss avant-garde
The bank owns nearly one thousand of these marvels of Swiss nouvel art
awaits us in the third basement of the building
We are the very first press outlet to be given permission to photograph it
“This is twenty-seven meters below lake level,” Martinoli whispers to us
“The room is water safe to withstand up to two tons of pressure.” It’s one of the most beautiful vaults in the world; no vault of Swiss accounts before it has ever exuded such glamor
Botta concludes the visit to his dulcet palace with: “It is a mysterious place that called for a kind of sacred feeling given its precious
Deposits disappear and become mirrors in which we each find our own identity

A partially collapsed cave containing the 12th to 14th century depictions of scenes from Buddha's life was unearthed last month by a team of Italian
US and Nepalese conservators and archaeologists in Mustang
a lost kingdom long forbidden to foreigners in the high Himalayas
"Finding the cave was almost like a miracle," said Luigi Fieni
a member of the team that used ice axes to cut its way into the inaccessible 3,400m-high cave in a region that for centuries was part of greater Tibet before being taken over by Nepal
Foreigners were only permitted to enter Mustang in 1992
and Mr Fieni's team began work nine years ago
restoring the spectacular wall paintings in a 15th century Tibetan monastery
When they inquired about other art treasures in the region
a villager remembered that as a boy he had seen a cave full of colourful paintings
the Mustang cave paintings do not reveal a Tibetan but a strong Indian influence
including the animals they depict - leopard
the style evokes the fabulous cave paintings of Ajanta
which predate the Mustang caves by several centuries."
The location of the cave has been kept secret to deter art smugglers
but the team call it "the snow leopard cave" as the animal's footprints were found inside
"The cave paintings have been affected by wind and rain and really need restoration," Mr Fieni said
and we're hoping now to raise funds for the project."
The simultaneous discovery of ancient Tibetan manuscripts in nearby caves has led to speculation that the caves might have been a teaching retreat on the lines of the Buddhist university in Nalanda
Mustang is of special significance to Buddhist experts because it is perhaps the only region where Tibetan culture and religion have survived over the centuries virtually untouched by time and modern Chinese colonisation
They speak the Tibetan language; their origin is in the Tibetan culture," said Lama Guru Gyaltsen
The opening up of the region has brought inevitable challenges to Mustang way of life
Young men are leaving the tiny kingdom in search of work
is certain to affect the tradition of rearing horses for transport and agriculture
Building techniques using mud are likely to be abandoned in favour of modern construction methods.
