Metrics details
The delivery of genetic cargo remains one of the largest obstacles to the successful translation of experimental therapies
in large part due to the absence of targetable delivery vectors
Enveloped delivery modalities use viral envelope proteins
which determine tropism and induce membrane fusion
Here we develop DIRECTED (Delivery to Intended REcipient Cells Through Envelope Design)
a modular platform that consists of separate fusion and targeting components
To achieve high modularity and programmable cell type specificity
we develop multiple strategies to recruit or immobilize antibodies on the viral envelope
including a chimeric antibody binding protein and a SNAP-tag enabling the use of antibodies or other proteins as targeting molecules
we show that fusogens from multiple viral families are compatible with DIRECTED and that DIRECTED components can target multiple delivery chassis (e.g.
lentivirus and MMLV gag) to specific cell types
including primary human T cells in PBMCs and whole blood
these studies highlight the potential of separating the cell entry and cell targeting functions of fusogens
we describe DIRECTED (Delivery to Intended REcipient Cells Through Envelope Design)
a modular platform for achieving programmable cell targeting that separates the fusion and targeting functions of fusogens and can be used with various packaging chassis
DIRECTED encompasses both natural and engineered cell fusion components as well as multiple strategies for cellular targeting
We show that these components can be used with lentiviral particles
which offer the capacity to deliver integrating genetic information
The modular nature of DIRECTED enables precise cellular targeting across diverse contexts and substantially expands the landscape of targetable cell types

these experiments show that DIRECTED allows the incorporation of cell type-specific targeting ligands or combinations thereof
which can increase transduction efficiency when combined with wild-type VSV-G
or completely redirect tropism when using VSV-Gdm
Achieving the potential of gene therapy will require a comprehensive array of delivery modalities that can be tailored to specific cargoes and target cells
Here we demonstrate that targeting various delivery modalities
can be reprogrammed using a suite of modular components
We capitalized on the ability to separate the cell entry mechanisms of these delivery vehicles into independent fusion and targeting functions to generate the DIRECTED platform
which combines interchangeable fusogenic and targeting components
A key advantage of DIRECTED is the compatibility with commercial antibodies (via both pAG-mediated antibody recruitment or SNAP-mediated covalent linkage)
which substantially expands the range of targetable cell types
including cell types that have been refractory to transduction
which showed highly efficient on-target delivery
could be used in co-cultures or organoids to deliver transgenes to specific cell types
pAG may not be suitable due to the competition of antibodies in serum
but the scFv and SNAP strategies can be deployed in these situations
although reducing the off-target uptake of DIRECTED particles by macrophages will be required to achieve efficient delivery in vivo
our in vivo experiments show lower delivery efficiency to monocytes and B cells for CD5-DIRECTED particles when compared to CreVLPs pseudotyped with wild-type VSV-G
the achieved transduction efficiency does represent a biologically meaningful proportion of T cells
which in the case of in vivo CAR-T therapy
would further expand upon antigen encounter and could enable the generation of CAR-T cells in vivo using a single-step protocol
we identified several principles for choosing cell surface receptors that are compatible with DIRECTED particles: (1) higher cell surface expression level of a receptor favors more effective delivery; (2) the targeted receptor needs to undergo endocytosis to enable the DIRECTED particles to get to the endosomal compartment and experience low pH
where the fusogen becomes activated; and (3) to increase the set of potential receptors
the SNAP strategy affords the most flexibility
presumably due to the reduced complexity of virus-receptor binding as the targeting antibody and virus are covalently linked
the use of NHS ester chemistry for the functionalization of antibodies with benzylguanine
necessitates individual optimization of the labeling step
Future research will be needed to determine the quantitative relationship between the biophysical properties of receptors
endogenous ligands or agonistic antibodies that increase receptor internalization may boost delivery efficiency
Future studies to optimize the efficiency of antibody-tethering on the virion surface
evaluate additional mutations that could help to reduce off-target delivery
and identify receptors that allow specific targeting of unique cell types in vitro and in vivo will further advance the DIRECTED technology and help to address the critical unmet need for cell type-specific delivery of molecular cargoes
the presented data suggest that SNAP-DIRECTED particles allow the integration of multiple targeting ligands
This approach potentially enables the manipulation of cell fate and cell state of specific target cells in situ and may allow for the delivery of therapeutic payloads
such as replacement genes or genome editing tools
both in a transient and integrating manner

Puerto Rico and the Dominican Republic are joining efforts to stop transnational criminal groups that attempt to move drugs to the United States or Europe on Caribbean waters
together they seized 2,723 kilograms of cocaine at different locations in their territorial seas
the Puerto Rico Police Joint Forces of Rapid Action (FURA
in Spanish) seized 450 kg of cocaine and detained two people 3 nautical miles off Punta Figuras
Authorities found the drug in 15 bales on a vessel sailing with its lights off
both Puerto Rico and the Dominican Republic hit narcotrafficking structures
Puerto Rico Police’s Intelligence Division and Maritime Division seized 1,600 kg of cocaine and detained a Dominican and a Venezuelan national at El Cocal beach
with bundles that they suspected were drugs
so they proceeded to inspect it and later confirmed that it was cocaine,” the Dominican website El Caribe reported
the Dominican National Drug Control Directorate (DNCD
in Spanish) seized 515 kg of cocaine in an interdiction operation carried out at a home in the Los Cacicazgos sector
“The residence was used by the criminal network as a center for the collection and preparation of drugs for export to Europe through the country’s ports,” the DNCD said in a statement
the DNCD and the Dominican Navy dismantled a criminal organization that used speedboats to smuggle drugs between the Dominican Republic and Puerto Rico
Authorities seized 158 kg of cocaine and detained 16 people
five firearms (two pistols and three shotguns)

Pneumococcal pneumonia is a potentially serious bacterial lung disease you shouldn't ignore
It can disrupt your life for weeks and even land you in the hospital
Many people think pneumococcal pneumonia is a cold or the flu
Pneumococcal pneumonia is caused by bacteria that live in the upper respiratory tract
and it can spread to others through coughing or close contact
Severe cases of pneumococcal pneumonia can lead to hospitalization and can even be life threatening
Pneumococcal pneumonia can strike any time
so now is the time to talk to a healthcare provider about vaccination
You can't get pneumococcal pneumonia from getting vaccinated
because pneumococcal vaccines do not contain live bacteria.
The CDC recommends adults 19-49 with certain chronic health conditions and all adults 50 or older to talk to a healthcare provider about pneumococcal vaccination
Pneumococcal vaccines are available today at many doctor's offices
local pharmacies and at some local health departments
Pneumococcal vaccination helps protect against two additional serious infections, meningitis, an infection of the lining of the brain and spinal cord and bacteremia
The immune system naturally weakens with age
being 50 or older puts you at increased risk for pneumococcal pneumonia
Other factors like certain chronic health conditions further increase pneumococcal pneumonia risk in adults 19 and older compared with healthy adults in the same age range
With each chronic condition your risk increases further
Having asthma can sometimes restrict me from doing things I love like riding my bike
hiking or playing frisbee with my border collies
I really try to prioritize taking proactive steps to help keep myself healthy
I’ve also learned that I am at increased risk of getting pneumococcal pneumonia because I have asthma
I thought I was too young to get a pneumococcal pneumonia vaccination but when my pulmonologist recommended it
I like knowing it’s helping to protect me against this potentially serious lung disease
It’s important to be an active part of your healthcare team
If you are 65 years of age or older or 19 or older and have certain chronic health conditions like asthma
ask your healthcare provider if pneumococcal pneumonia vaccination is right for you
Adults 19 or older with chronic health conditions such as COPD
and chronic heart disease face greater risk for pneumococcal pneumonia
Adults 50+ are at 6.4x greater risk for pneumococcal pneumonia compared to adults aged 18–49
Adults 65+ are over 10x more likely to be hospitalized with pneumococcal pneumonia than adults aged 18-49
Answer these three questions to learn more about your risk
chronic health conditions and lifestyle factors may increase your risk for getting pneumococcal pneumonia
If you’re 19 or older with a chronic health condition or 50 or older
Even if you are active and otherwise healthy
an important thing to remember is: If you're 50 or over
our immune systems aren’t as effective at fighting off infections and helping to protect us from vaccine-preventable disease
certain chronic health conditions can make the body more vulnerable to serious illnesses such as pneumococcal pneumonia
and smoking history can contribute to an increased risk for getting pneumococcal pneumonia
Talk to your healthcare provider about your risk factors and how vaccines may help protect you
Certain Chronic Conditions Increase Risk in Adults Aged 50+*
Your age and health conditions may put you at increased risk for getting pneumococcal pneumonia
Your age and smoking history may put you at increased risk for getting pneumococcal pneumonia
Adults aged 50 or older are at increased risk due to age alone
Although you haven't selected any health conditions or behavior choices that would increase your risk
age is still a key risk factor for pneumococcal pneumonia due in large part to the natural
Although your age and health conditions are not risk factors
your smoking history may increase your risk for getting pneumococcal pneumonia
Although your age and behaviors are not risk factors
you have health conditions that may increase your risk for getting pneumococcal pneumonia
Certain Chronic Conditions Increase Risk in Adults Aged 19-49*
the risk of pneumococcal pneumonia increases with the presence of certain chronic conditions
Although you're not currently in an elevated-risk age group
your health conditions and smoking history may put you at increased risk for pneumococcal pneumonia
Your answers to these three questions indicate that you are not in an elevated risk group
it's always important to recognize your risks as you age

Lentiviral vectors (LVs) used to transfect cells for gene expression can withstand shear rates that are twice as high as those normally used and still maintain comparable productivity
That insight from researchers at University College London removes some of the hurdles that
have constrained gene therapies from advancing in clinical trials
Reporting in Biotechnology & Bioengineering
evaluated the manufacturing processes various vectors experience and the conditions that lead to vector loss
They assessed a three-plasmid system and a four-plasmid system (both pseudotyped with the RDpro
and VSV-G envelope proteins) in terms of process shear
and the impact of chromatography buffers on the lentiviral vectors
To evaluate shear forces during diafiltration
the researchers used an ultra-scale-down (USD) tangential flow filtration (TFF) mimic
Many researchers perform TFF at flow rates of less than 500 s−1 and shear rates of less than 2000 s−1
began with a flow rate of approximately 800 s−1 and a shear rate of 1000 RPM
the overall functional titers appear to increase with higher shear
VSV-g envelope protein has a mild decrease from initial to 3,000 RPM
but titers from this point onwards are maintained,” the authors noted
maintains high permeate flux rates and reduces membrane fouling
clarification by membrane filtration had the greatest effect on the lentiviral vectors
They found “a weak correlation of lower functional titers with pump flow.”
Of the four filter materials tested—polyvinylidene difluoride (PVDF)
mixed cellulose esters (MCE) and nylon—the PVDF filters consistently recovered more lentiviral vector than the others
have demonstrated comparable results to the USD system,” Rayat’s team reported
“These results reinforce the need to…test new LV products in terms of their robustness for manufacture,” and to apply rational bioprocess development to lentiviral production
may be like those experienced by the rational design of recombinant protein production

As a designated “sanctuary city,” Denver does not cooperate with the federal government on immigration enforcement
“We’re not going to sell out those values to anyone,” Johnston added
“We’re not going to be bullied into changing them.”
The response from Tom Homan, a hardliner Trump appointed as his “border czar” after winning the election
Appearing alongside Texas Governor Greg Abbott — a staunch ally of Trumpism — on Sean Hannity’s Fox News show
Homan warned that he would not let Johnston hinder his plans
we agree on one thing; he’s willing to go to jail
“It’s a felony if you knowingly harbor and conceal an illegal alien from immigration authorities
It’s also a felony to impede a federal law enforcement officer
This standoff is the latest chapter in an escalating battle
Since Trump’s election victory less than a month ago
Democratic governors and mayors nationwide have vowed to resist cooperating with his immigration agenda
and other members of the president-elect’s circle have issued stark warnings to the officials who have spoken out against the Republican’s plan to carry out “the largest deportation operation in American history.” Threats include imprisonment
as suggested by Homan in Johnston’s case; severe cuts to federal funding for defiant states and cities
which could cripple local budgets; and the deployment of thousands of federal agents to enforce immigration laws directly in noncompliant communities
Mayor Johnston reiterated his stance in a more measured statement
we respect the law and enforce it without fear or favor across every inch of our city
If Donald Trump tries to break the law and abuse his power
and we will do everything in our power to protect those who live here
We are considering a number of options to strengthen protections for all our residents
and we continue to provide education about the rights of our immigrant community so they can best protect themselves from any unlawful actions,” the statement said
A spokesperson for the mayor added that Denver would withhold further comment on a federal policy that has yet to be detailed
However, Denver is far from the only city resisting the Republican’s plans
Los Angeles officially declared itself a “sanctuary city.” Although California’s largest city has operated under sanctuary policies for decades
this legal codification strengthens its stance by explicitly prohibiting both direct and indirect sharing of data with federal immigration authorities
This move by Los Angeles sparked a strong response from Homan
“If I’ve got to send twice as many officers to L.A
then that’s what we’re going to do,” he said
This is going to happen with or without you.”
Similar tensions were seen on the other side of the country
has vowed to fight the mass deportation effort
“We are not cooperating with those efforts that actually threaten the safety of everyone by causing widespread fear and having large-scale economic impact,” she said
Massachusetts’s largest city has reinforced its commitment through the Trust Act
which prohibits police from stopping or arresting individuals solely for immigration enforcement purposes
in keeping with his and Trump’s combative tone
lashed out at Wu during an interview on Newsmax
describing her as “not very smart” and reiterating that harboring undocumented immigrants is a federal crime
“Either she helps us [or] she gets the hell out of the way because we’re going to do it,” Homan said
“To those people who say they’re going to stop us from what they’re doing
they will not [...] You’re not going to stop us
The consequences Homan alluded to include cuts in federal funding to states and cities
a common leverage tactic in negotiations between Washington and local governments
I guarantee President Trump will do that.”
The potential withholding of federal funds could have significant financial consequences
California received approximately $163 billion in federal grants
While these figures were unusually high due to pandemic-related assistance
federal funding remains a critical revenue source for states
ranking as the second-largest revenue stream in fiscal year 2022
Trump’s deportation plan, however, is fraught with uncertainty. While the president-elect and his team have made their goals clear, the mechanisms for executing them remain ambiguous, especially given the resistance from states and cities refusing to cooperate. States like Texas and Florida have pledged full support for Trump’s immigration agenda
but a significant number of other jurisdictions are pushing back
intensifying the already heated political climate
But with control over all three branches of government
Trump and his team appear determined to press forward with their agenda

MI -- A Flushing couple is out on bond after the federal government claims that they purposely hid profits from millions in foreign investments from tax officials
are accused of purposely failing to claim their foreign bank accounts that were funded by profits from the millions the couple invested in Costa Rican property on their federal tax returns
which was unsealed July 10 in Flint federal district court
the couple has an ownership interest in two condominiums and Gray owns and operates Hotel Cocal and Casino
Gray explained in an email he sent to a federal informant that he does not report capital gains taxes on his condominium activities in the United States
you have capital gains and would have to pay tax in Costa Rica no capital gains,” Gray wrote in the email
A revolving credit application uncovered by the government during its investigation shows that the condominium assets owned by the couple are valued at $5.68 million and the hotel and casino is valued at $2.86 million
During a face-to-face meeting with Gray in May 2011
an undercover federal agent posing as an investor asked Gray how to report property owned outside of the United States on a federal tax return
“You don’t,” Gray told the agent according to the complaint
Gray allegedly told the agent that he began moving his bank accounts from Panama to Costa Rica after the U.S
signed a treaty with Panama making tax information for U.S
citizens with more than $10,000 in Panamanian bank accounts available to the federal government
Gray told the agent that he would then place all the profits from the condominiums into the foreign accounts and use a bank-issued debit card so the money wouldn’t have to be moved through the U.S
a search warrant was executed at the couple’s Flushing home
business records and copies of emails that show the couple’s foreign properties and financial accounts
Three firearms were also seized from the residence
The complaint alleges Gray was in violation of federal law for possessing the firearms because he is a convicted felon
Gray was convicted of conspiracy to possess with intent to distribute cocaine in federal court in 1986
Amerling-Gray was released on a $100,000 unsecured bond
while Gray was released on a $250,000 unsecured bond
The couple does not currently have an attorney after their former attorney
Amerling-Gray declined to comment on case when contacted by The Flint Journal

and some debris separate the coastal bluff in the Barrio Obrero community of Arecibo from the ocean-view car wash where Christian works
who has lived in this community all his life
said how the neighbors have tried to find options to tackle the accelerated coastal erosion rate in recent years
The result has been a makeshift landfill made with discarded construction materials
he says that municipal politicians rarely stop by the area
and that these sporadic visits almost always happen during electoral campaigns
“Because this is a small neighborhood
almost no one cares,” he tells the Center for Investigative Journalism (CPI
while looking for the liquid to shine car tires
In the past, the Arecibo municipal government said there were no resources to implement a mitigation plan in this coastal area
Former Mayor Carlos Molina said the only solution for residents in vulnerable zones was to find another house somewhere else
the residents of Barrio Obrero throw objects such as brick fragments
pipes and pieces of tile onto the eroded slope with the hope of forming a breakwater that protects their properties for a while
but as long as it’s not garbage,” Christian said when discussing how the people in his neighborhood struggle to try to protect themselves from erosion and from the episodes of strong tides that threaten the existence of their residences of this coastal community in Arecibo
with the arrival of a new administration in Arecibo
an ordinance was signed to create the town’s first Office of Planning and Territorial Management
saying that in her newly created office they will work on strategies to manage the coastal erosion problem in Barrio Obrero and in nearby communities
Like other areas west of the Río Grande de Arecibo, the Barrio Obrero community has faced the erosion of its coastal slope, according to “The study of the beaches of Puerto Rico Post-María” research study
One of the main researchers on the project
describes the problem in some of these areas of Arecibo as one of coastal bluff erosion
It is an erosion process that is just starting to be examined in Puerto Rico
and which is different from beach erosion and wearing away of other areas of the flat coast
If you have that exposed to a coast with regular waves
with hurricanes that are becoming increasingly [stronger] due to the effect of climate change
Added to that is coastal mismanagement in the past
so you have the perfect equation to speed it up,” Barreto explained to the CPI
was one that marine geologist and her work team from the University of Puerto Rico (UPR) noticed while doing field work to learn how much Puerto Rico’s beaches had changed after Hurricane Maria
Although the research was not intended to study the phenomenon of coastal bluff erosion
coastal bluff erosion is more difficult to identify through aerial photos
and her research in Puerto Rico has been more limited when compared to flat coast erosion
El Cocal beach in the town of Yabucoa, in southeastern Puerto Rico, presents another significant case of coastal bluff erosion, the second part of the study reveals
the CPI found that municipal officials said they were aware of the problem and the danger to properties in high areas but admitted that specific mitigation strategies for coastal bluff erosion have not been implemented
“We don’t have much information about the elevated coast,” Luis Rivera
the area of El Negro beach also shows a case of coastal bluff erosion
From El Cocal beach dozens of properties that are part of El Cocal Country & Beach Club can be seen on the slope
which includes units available for rent through the Airbnb platform
A visit to the area reveals how vulnerable the slope that divides this complex from the popular beach has become
The sturdy natural wall that once separated the residential complex from the beach has narrowed as a result of erosion and landslides
further undermining the roots of the trees and palms trees there
When Rivera was asked about what measures the municipality has taken to address the dangers faced by those who stay in these housing and rental units
since it is a “private property.”
“El Cocal [Country & Beach Club] is a plot of land where several people bought and got titles
but it’s a plot of land that hasn’t been segregated
We can see the effects of erosion from the public area [of the beach]
we would have to go in there at the request [of the residents],” Rivera explained
the area adjacent to Kikita Beach and the Ojo del Buey reserve in the Mameyal neighborhood of the northern municipality of Dorado
also face a coastal bluff erosion problem that includes the area where there are properties for rent through Airbnb
Although his reasons are different from those outlined by Yabucoa municipal officials
the mayor of Dorado has not gotten involved with managing and mitigating the coastal bluff erosion that is happening in his town
He held the central government accountable
“This is really the responsibility of the Department of Natural and Environmental Resources (DNER)
[the agency] has refused to take any responsibility
there’s an area that could affect residences in the future
have been trying to qualify for to solve the problem and we weren’t able to get Department [of Natural and Environmental Resources] to help at this time,” Dorado Mayor Carlos Lopez told the CPI
Regarding the case of Mameyal and the area of the El Ojo del Buey reserve
where there are areas of coastal bluff erosion
which is a type of metal mesh rectangular box filled with rocks used as a barrier
He also said he will request federal funds to be able to conduct ocean studies to design a protective structure
although he did not explain why he waited until now to do this
The CPI contacted the DRNA for a reaction to the mayor’s statements
While it is being decided whether the responsibility of addressing coastal bluff erosion falls on the town of Dorado or the DRNA
the Atlantic Ocean continues reclaiming its space
The episodes of strong swells caused by cyclones or cold fronts along Puerto Rico’s northern region push the ocean into the Mameyal’s narrow streets
Business and apartment owners in elevated areas near Kikita Beach also toss rocks at the shoreline area to try to mitigate erosion
which the Mayor himself claims to be unaware of at times
Although these practices respond to people in fear of losing their business or property
their consequences are not always favorable since it represents a type of informal mitigation that does not respond to the coastal studies required in these processes
That’s why mitigation decisions cannot be made without following the processes
but what people might think of as an option may be the worst medicine,” Barreto warned
“The mitigation strategies have to be based on the behavior of the coast
It has to go along with community participation
It has to be an analysis among the community
They cannot be independent decisions,” said the also professor at the Graduate School of Planning of the UPR’s Río Piedras Campus
several reports and videos have documented the progressive deterioration and the Paseo’s existing critical condition
One of its sections was closed to the public due to the vulnerability of the slope on which the Paseo’s structure stands
The unsafe condition of this recreational area that cost $32 million in public funds forced the House of Representatives’ Commission for the Development and Supervision of Public Funds of the Capital City
Cataño and Guaynabo to launch an investigation into the controversial project in May
it was revealed that it was not clear whether the Municipality of San Juan or the Department of Transportation and Public Works (DTOP
in Spanish) was the entity that should assume the main control over the Paseo
the Infrastructure Financing Authority has stated on several occasions that its responsibility for the project ended once construction was completed
While the Municipality of San Juan and government agencies point fingers at each other without assuming responsibility
the erosion of the coastal bluff that supports the Paseo continues to gain ground
putting the people who pass through the area on a daily basis at risk
Some open sections of the Paseo are supported by ground that is increasingly prone to landslide events
chairman of the College of Engineers and Surveyors of Puerto Rico’s Earthquake Commission
“The issue there [in Puerta de Tierra] is that the sea is very close to that sloping terrain
where it’s about 30 feet high between where the street is and the square
and down to the sand,” Rivera explained to the CPI
“Soil studies and recommendations were made to put some meshes that didn’t work
It is completely steep and that’s a very serious problem,” added the engineer
who also warned that any cyclonic event that occurs this year could accelerate the landslides
prompt the shutdown of more sections of the Paseo
The firm GeoCim was contracted in April 2015 to carry out the geotechnical study for the Paseo Lineal in Puerta de Tierra
which is supposed to have included measures aimed at controlling coastal erosion
While both types of beach erosion happen in a coastal context
their characteristics and processes of change are different
This is why mitigation and adaptation strategies and the development of public policy have to be specific
boosting research that contributes to the understanding of coastal bluff erosion and the main reasons why it happens is necessary
Many of these coastal slopes in Puerto Rico feature a combination of different types of sedimentary rock
And each combination poses a different density
Geomorphologist Banery Mujica explained to the CPI
when addressing one of the reasons for the vulnerability in areas where there are elevated coasts in Puerto Rico
the material comes mostly from the mountainous central region
Especially along Puerto Rico’s northern area
there’s a combination of sedimentary material that
includes different types of sedimentary material,” said the scientist
speaking of the convergence of rocks such as limestone and that of volcanic origin in some parts of the north of the island
especially in the northern part of the Capitol [building]
This material comes from the Rio Grande de Loíza
which was pulled by the basins and the marine currents
which were collecting all this material in the north of Puerto Rico.”
A tour of the area under the Paseo Lineal in Puerta de Tierra not only shows the fragility of the slope
but also allows the identification of the presence of two types of sediments that converge in this coastal formation
“In the lower part it’s more limestone and in the upper part it’s more sedimentary material of igneous origin,” said the also professor of the Department of Geography of the UPR’s Río Piedras Campus
The problem of accelerated erosion in Puerto Rico must be addressed by combining several scientific disciplines
Mujica recommends that for construction projects in coastal areas
soil studies carried out by geologists are not the only reference for decision-making
but that they must integrate geomorphological analysis
something with which renowned Geomorphologists Maritza Barreto and José Molinelli agree
all that coast of San Juan is a combination
It’s exactly the same mix that you will see in Vega Alta and Vega Baja
since the Puerta de Tierra coast in San Juan is a bluff
erosion behaves differently,” Mujica noted
the study of coastal erosion in Puerto Rico should not only take into consideration the current climate crisis and the rise in sea levels
but also aspects such as the geomorphological processes that happen in the island’s interior and the problem of mishandling of rivers

Cuba is not alone as the enemies of the Revolution pretend
said the Head of Government in this seaside resort city
In the presence of more than 330 professional organizers from 20 countries
Marrero commented that tourism in the largest of the Antilles is managed under complex conditions compared to other destinations in the region because of the sanctions of the U.S
the activity continues to develop with the efforts of all and innovation
Cuba has the potential to establish itself as a destination for event tourism
hotel facilities with infrastructure and trained personnel
in addition to the nation’s historical
About what happened during these days in Cuba’s sun and beach destination par excellence
he highlighted the relevance of the exhibitions
marketing and sustainability in the activity of meetings and professional events
He urged that after this event the sector in the archipelago should take advantage of what it has learned; so much experience and knowledge must be put to good use
which was also attended by Juan Carlos García Granda
Marrero Cruz praised the fact that the organization of the meeting included the pre-congress session IMEX COCAL Future Leaders Forum
a unique opportunity for young people from several Cuban universities and other Latin American nations to exchange and learn about Congress
He recommended COCAL’s directors to take into account the university students from the largest of the Antilles so that they can bring their experiences to the 40th edition of the Congress and thanked them for having shared and “left a mark that Cuban tourism will know how to take advantage of”
The MICE segment is a travel modality that is carried out for professional reasons and is of great importance for the so-called smokeless industry
as it generates a high economic contribution
de-seasonalizes demand and positions the destination.

Cocal/Mafeking councillor Renelle Kissoon lives in the village and told Newsday several roofs were blown off near her home
“We had a lot of roofs that were blown completely away and that’s been our biggest concern.”
A home on Bel Air Road which is near to Grand Lagoon Village
lost its roof after heavy rain and gusty winds on Friday morning
Kissoon said there were also reports of roofs being blown off in other parts of the district of Cocal/Mafeking
"We’ve also had some fallen trees and we’ve had power outages in a couple of streets because power lines were blown down.”
When Newsday spoke with Kissoon shortly after 9am on Friday
she said it was still raining and that repairs to the damaged homes in her immediate area would have to be done when it stops raining

Coca-Cola’s commitment to investing in our planet and in its packaging has earned the company multiple awards at the Environmental Sustainability Conference
organised by ImpactReports Africa and Brand Communicator
environmental sustainability goes beyond one-off philanthropic interventions to long-term commitments
the maiden edition of ECOSEA saw the convergence of public and private sector stakeholders in the environmental sustainability space
deliberate on Smarter Waste Management for Safer Cities
The Role of Communication in Environmental Sustainability
and Net Zero Emissions: The Journey to 2060
described it as an annual platform that champions the cause of environmentally sustainable actions in Africa
With the evolution of corporate sustainability practices from corporate philanthropy into an integral part of business models and operations
Coca-Cola Nigeria is blazing trails and transforming communities
Coca-Cola emerged as the winner in both categories
namely ‘Award for the Most Outstanding Beverage Company in Environmental Sustainability’ and ‘Award for the Eco-Friendly Bottled Water Brand of the Year’
Nwamaka Onyemelukwe emerged ‘Environmental Sustainability Professional of the Year’
themed “Smart Waste Management for Safer Cities”
Onyemelukwe explained that Coca-Cola’s World Without Waste initiative is anchored by three fundamental goals: making 100 per cent of its packaging
recyclable globally by 2025— and using at least 50 per cent recycled material in its packaging by 2030 (Design); collecting and recycling a bottle or can for each one it sells by 2030 (Collect); and bringing people together to support a healthy
Coca-Cola announced an industry-leading reusable packaging goal which states that by 2030
the organization aims to have at least 25% of its beverages worldwide by volume sold in refillable/returnable glass or plastic bottles or in fountain dispensers with reusable packaging
This builds on its already strong track record with refillable packaging
especially in Africa and Nigeria in particular
Another packaging innovation by Coca-Cola is the Sprite packaging transition
one of its largest global sparkling soft drink brands
transitioned from its iconic green bottles to clear PET to enable easier conversion into new bottles by increasing the supply of high-value recycled plastic in the after-use market
in its journey towards achieving “A Safer Environment”
through investments in recycling interventions and innovative packaging
Coca-Cola Nigeria’s sustainability actions are well-deserving of these accolades
Nigeria is ranked 168 out of 180 countries in the Environment Performance Index (EPI) 2022
The country had a score of 28.32 out of 100 for “environment and sustainability,” placing it 41st out of 46 sub-Saharan nations
This was published in a 2022 report by researchers from Columbia University’s Center for International Earth Science Information Network and Yale Center for Environmental Law & Policy
This indicates that the most populous country in Africa struggles to safeguard its people from environmental health concerns that include poor air quality
It is within this context that Coca-Cola Nigeria is working with social enterprises and organisations with a focus on the circular economy to deal with plastic waste and contribute towards improving Nigeria’s environmental sustainability performance

the carpark of S&S Supermarket in Mayaro will be transformed into a farmers’ market
where over 30 vendors and small businesses are expected to ply their trade
Funds raised from the market will go towards helping over 100 families in Mayaro
Leading the effort is 24-year-old Cocal/Mafeking councillor Renelle Kissoon
it’s very hard to think about yourself without thinking about everyone else
You want everyone to be just as comfortable as you are.”
Kissoon came up with the idea in early November while thinking of activities to help constituents during the Christmas season
she approached farmers in Mayaro who agreed to sell their extra produce and donate all the proceeds from those sales
Kissoon said several small business owners also stepped forward to help and pledged part of their proceeds to the initiative
Visitors can also expect entertainment and giveaways
Kissoon said any funds raised from the market will go a long way
“I know these families (assisted with funds from the market) will appreciate whatever we can help them with especially around Christmas time
I always look for families I can help because I see myself in them.”
She said the proceeds will help provide constituents with food hampers and home building materials
Past national censuses by the Central Statistical Office
have shown the Mayaro area to have a high poverty rate — something with which the councillor can relate
there were always things we (my siblings and I) wanted that we couldn’t have because of our financial circumstances
that’s why I’m in this field (as a councillor) to play a social role in my community.”
Regardless of the socio-economic challenges in Mayaro
Kissoon doesn't want residents to feel ashamed about their circumstances
but rather to continue to work together to developing the area
among them owner of S&S Persad Supermarket Sunita Persad
“Sunita’s idea was to do something to give back to the community
“When I pitched my idea (for the farmers’ market)
Persad is also providing Kissoon with sponsorship and tents among other things
Other sponsors include BpTT and Rotoplastics Trinidad Ltd
whose bins will be placed throughout the market for people to donate canned items
Kissoon is calling on people anywhere to reach out and assist in any way they can
She said people from other areas such as Princes Town
and Sangre Grande have offered to be a part of the initiative
because I know how much help I got growing up.”
People visiting the market are reminded that covid19 protocols will be in place which include the wearing of masks
Anyone interested in supporting or participating in the farmers’ market can contact Kissoon at 778-8026 and S&S Persad Supermarket

Also is the fact that it has been recently raided by authorities to prevent it from being a brothel as well as a place that owners are presenting as a family hotel
I do not know about you but I would not want to take my wife and kids to a place where there are prostitutes hanging out both around the pool and exiting rooms of clients
After a recent interview with the chief of police in Jaco
it was discovered that the Hotel Cocal and Casino would be subject to raids on a regular basis
As a person that used to visit Costa Rica for much of the year
having police in heavy armor and assault rifles coming in to ask me for my passport and not letting people leave until they checked everyone is not how I want to potentially spend an evening

Wow they must be really competing with the Beatle Bar
Why do I care what taxes they are paying or not paying to to the US
This is clearly an attempt to harass them because they are offering a better option in Jaco
Oh and by the way anyone going to Jaco to take the wife and kids on a “Family Vacation ” is and idiot because everyone knows its not that type of destination
the rumor is that they may have to close down for a while because the US and CR banks are freezing their accounts and they will not be able to use their merchant accounts for credit cards etc.
just trying to let people know whats up… it would really suck if you had a reservation and they were closed and you couldn’t get back your cc deposit…the other rumor story is that the main owner cannot come back to CR while all this is going on – so it can affect the condos and his business…and he is facing jail time for not completing some tax form and some gun charge because he is an ex-con

then you are subject to both civil penalties which can add up to substantial
Just look at recent article published about the owner of the Cocal Casino in Jaco

Hotel Cocal is the main attraction and is currently the center of Jaco at night at any given day of the week
When the hotel got renovated it added a tower of posh condo units that offers a more relaxed ambiance compared to the hotel itself
The hotel boasts of 42 rooms that are either facing the ocean or the poolside and have amenities like safes and fridges
It also has a small casino that serves its guests after seven in the evening for games like rummy
slot machines and Caribbean stud and upstairs there is a poker room that also serves as a sports book where you can place your bets directly
The main focal where all the steamy transactions happen is in the poolside bar of the hotel
At night ladies swarm the place looking to meet generous men looking for company at a price
If you come in earlier than 7pm make sure to wait until later that night before choosing the girl who would accompany you for the night as you might miss your chance of meeting a hotter and more gorgeous lady
if you think you have seen it all then you are mistaken
Hotel Cocal women who throng the poolside come dressed to impress with their sexy dresses
makeup and the likes that you would mistake most of them for models or actresses which some of them are
blondes and redheads in all shapes and sizes; athletic
fair skinned and all shades in between; you name it
You will find all bra cups and sizes either enhanced or natural in this place so be warned that you may find yourself a little overwhelmed with all the delicious morsel presented to you
By 10:30 pm all girls frequenting the joint have already arrived so you can start choosing the most beautiful and sexiest girl that you would like to spend a couple of hours with
they vary depending on how good your negotiation skills are but they usually start at $150
this is business for the women and you got to make sure that important details like prices
services offered and length of stay should be agreed on before you leave the place or you might find yourself in a difficult situation; prostitution is legal in Costa Rica and women working in this industry can call the police for help if you do not pay the price they are expecting you would or if not they will get their friends involved so be smart with your transactions
be smart and make sure that your valuables and money are in the safe to avoid getting outsmarted by the woman you decided to take home with you

he talks Jaco nightlife and names his favorite places
but no one seems to talk about it is this: Tell me about the nightlife in Jaco
As a travel consultant in Jaco, who specializes in fishing
Costa Rica is famous for its natural beauty
and outside of the capital city of San Jose
Jaco’s nightlife is by far the most vibrant
Nowadays Jaco is one of the best beach destinations in Costa Rica
But for all you night owls and party people
Jaco also offers a great party scene for those looking for excellent nightlife
I’ll break the following suggestions into two categories
Jaco Blu is one of my favorite Jaco beach bars
but is also super popular at night as a club
sitting right on the beach with pools in the center
Please note that this place is currently closed for a refurb
Republik Lounge only opens on Thursday
A post shared by Republik Lounge (@republikcr)
Every night is ladies’ night at XTC
every night except for Mondays and Tuesdays
On the second floor on the east side of the main street (not the beach side) in the center of town – you’ll find it
A post shared by XTC Jaco Beach (@xtcjaco)
Orange Pub could be the largest club in Jaco – the space is massive
and go-go dancers around the bar and dance areas
They also have some nice VIP sections that make for excellent people watching
A post shared by Orange Pub (@orange.pub)
Le Loft is the granddaddy of clubs in Jaco
the go-to spot for amazing all-nighters that don’t stop until the sun comes up
The perfect place to finish your Jaco club crawl
ice-cold beer and plenty of beautiful people to hang out with
party like a rockstar” is what they say here
Located at the north end of town, right off the main road as you come to the main strip. GSpot calls itself a “fusion between the best of a bar
and has a two-pole dance floor in the center
A post shared by Gspot Jaco Beach (@gspotjacobeach)
Centerfolds is above La Loft in the center of Jaco
after moving from elsewhere in town during the pandemic
It’s reopening and rebirth as part of the Le Loft family ensures a well-run gentleman’s club for Jaco
So there is no real way to describe this property, but it would be churlish to keep it out of any guide to Jaco nightlife. Years ago, Cocal was a great beachfront family hotel
but has since changed to THE place to go for guys looking to mingle with beautiful women
Cocal has some of the best bar food around
with great drinks and endless eye candy to view or socialize with
If you’re a guy traveling with your family or with a girlfriend/spouse
what I’ve listed above – in my opinion – are the best places for party people in Jaco to check out
I’ll keep looking around and update where necessary
