This innovative vineyard technology provides growers with a modern
sustainable and durable method of supporting and cultivating their grapevines
The history of viticulture stretches all the way back to the Neolithic period
while the Romans were among the first to adopt the trellis system that would lift vines from the floor and lead to the creation of what we would recognise as modern vineyards
With this technique largely unchanged for hundreds of years
the difficulties associated with maintaining a sturdy and reliable system have confronted growers for millennia
voestalpine’s leova system is a long-lasting and cost-effective way of supporting grapevines on wine growers’ farms
as the first set of poles installed in the 1960s
are still in use today and show little sign of needing replacement
Josef Lamplmayer is Managing Director of voestalpine Krems GmbH
a company of voestalpine’s Metal Forming Division
which produces the leova system and is a world specialist in innovative tubes and sections
mechanical engineering and trading partners
it has the best cost-performance-ratio when compared to alternatives.”
“The leova combines a complete system for all vine training processes,” he says
“with advantages like quality steel from our own steelworks
extremely long-lasting and weather-resistant surfaces and high quality from state-of-the-art precision manufacturing
One of the key aspects of the leova system is the high-quality steel
employs state-of-the-art methods when roll-forming the tubes that make up leova
The material of the poles is hot dip galvanised steel
allowing the surface to oxidise and form a protective layer of rust that shields the steel below
“We are confident the steel we use is better than other materials from an ecological perspective
With around 75 per cent market penetration in Austria
vineyard owners are becoming more aware of the unique characteristics of the leova system
“We recently had an end customer asking about the carbon footprint of leova,” says Lamplmayer
“This is one of the first requests we’ve had of this nature
but we are confident that steel is the more sustainable solution when compared to other materials
“Our steel lasts longer than competitor materials and
whereas the recycling of wooden poles is a challenge
or even impossible due to the required chemical treatment for weather resistance
“The assessment of environmental impacts of products requires a holistic approach that takes the entire lifecycle into consideration
leova steel vineyard poles outperform other materials and underscore the clear advantages of this material,” he adds
The leova system also helps vineyard growers in other ways due to its ‘unique wire clamping system’ that allows for it to be tightened quickly and easily
With wind and other factors contributing to a loosening of the wire that supports the grapevines this is particularly important
and the special end poles for fixing the wire have rendered this problem a thing of the past
voestalpine’s HARVESTAR system includes super strong stamped posts which are designed especially for use in combination with harvesting machines
steel’s popularity in viticulture can only be set to increase as growers become more aware of its unique qualities
particularly its sustainability credentials
“The consideration of sustainability aspects along the whole value and supply chain is continuously gaining in importance,” he says
“Steel poles are not only the most durable vineyard poles
but also the most sustainable with the lowest environmental impacts.”

machetes sometimes come stuffed with a variety of fillings
each in a different section of the tortilla.
Machetes are a street food, usually served at taco trucks or small stands. They may have originated in Mexico City’s Colonia Guerrero, where the Montoya family has been making them since 1964 at the ever-popular Los Machetes Amparito
The giant quesadillas have since spread across Mexico City
after scouring the city for the hearty treat
I suggest we nickname “Machete City.”
Casita Nicole became the first machete purveyor in Austin when it opened six years ago
which she visited as a child during family trips from her home state of Hidalgo
the street food signifies nostalgia and entrepreneurial spirit
“I just remember too much about them and found my way to making them,” she explains
started their trailer with $20,000 in savings and named it Casita Nicole in honor of their daughter
They use recipes Vizuet developed from her childhood memories and further visits to Los Machetes Amparito
“We were selling so much that we couldn’t do it by hand anymore,” she says
“We had to buy [a special tortilla press] to make them.”
To understand why Casita Nicole is so beloved
you need only bite into the flor de calabaza machete
soft and gooey in contrast to the crispy-edged corn tortilla
But my favorites were the campechano (a mixture of chorizo and carne asada) and the juicy
It’s just one of the many side businesses she and her family have
Another is a mechanical bull they rent out for parties
That operation is overseen by her twelve-year-old son
The one-year-old Taqueria Casita Vizuet trailer sits in a grocery store parking lot on North Lamar Boulevard
in a part of the city dense with mobile food vendors
Maria and her husband had operated a second location of Casita Nicole for Ivonne before opening Casita Vizuet on their own
Although initially the independent operation was a surprise to Ivonne
she says that the family drama is behind them
She’s happy to see machetes flourish in Austin: “It’s good for competition.”
the machete to order is the herbaceous flor de calabaza
mixed in a generous foundation of cheese in a crunchy
It’s best enjoyed under the wood-framed seating area
which is decorated with hand-painted signage advertising machetes and other street foods available from the trailer
Maria says that although she is from Hidalgo
It’s there where she worked as a counselor
“It’s what I really love to do,” she says
though making machetes isn’t bad either
Taqueria Casita Vizuet is a not-to-be-missed machete spot
A few blocks up the road from Taqueria Casita Vizuet
Machetes Doña Leova serves from the parking lot of Austin Appliance Rebuilders
next door to a Chuy’s Tex-Mex restaurant
and across the street from an indoor Latin American flea market
This family operation had its grand opening in August and is overseen by Leticia Santos Gonzalez and her brother Gonzalo
The menu has a long list of filling options
with standouts including shrimp (a customer favorite)
Don’t hesitate to order the flavorful cecina
Its salinity is offset by the slick caramelized onions and peppers
narrow quesadillas are served with palate-cleansing cucumbers and radishes
as well as a fiery green chile and pickled onions
Machetes Doña Leova has a colorful covered seating area with picnic tables
cheerful Christmas lights are wrapped around every post
In stark contrast to the other machete purveyors I visited, Aparicio’s specializes in all manner of flashy Mexican street foods
Here you can try tacos made with Flamin’ Hot Cheetos-infused corn tortillas
The menu even includes tacos topped with flakes of edible gold.
is a disappointment because the wildly popular corn puffs lack kick
Owner Victor Aparicio suggests adding cilantro
but I think it’s perfect the way it is
Wash down the machete or any of the other dishes with one of several creative milkshakes
Aparicio says he’s been crazy since he was a kid
“Every day is crazy,” he laughs
And if you’re not laughing while enjoying his outlandish and no-holds-barred dishes
there might be something wrong with your sense of humor
Moldovan President Maia Sandu announced that a new border crossing with neighboring Romania became operational
A statement Tuesday by the Moldovan presidency noted that Sandu said a pontoon bridge was built between Leova and the town of Bumbata in Moldova and Romania
Sandu said the bridge above the Prut River was built in eight months
“We will build even more bridges to be closer to Romania and the EU,” she said
Moldovan Interior Minister Ana Revenco said during an interview with local television March 22 that Moldova and Romania will launch a joint border control at the Albita-Leuseni checkpoint
Revenco said the Leova-Bumbata checkpoint would open in the spring
expressing that it would ensure accelerated traffic at the border
is a candidate for EU membership after having applied to join the bloc in March 2022

felt a tingling sensation in his left thumb
uncontrollable shakes in my hand up to the wrist,” he recounts
they told him he might have Parkinson’s disease
starting with what they called the essential tremor
one of the early symptoms of this progressive disease
Parkinson’s gradually damages the cells of the nervous system
leading to agonizing neuronal death and its treatment remains under investigation
there is a region known as the substantia nigra
The nerve cells send messages to both sides of the brain via neurotransmitters
which controls motor functions like moving an arm or a leg
This institution conducts cutting-edge research and generates new knowledge to address and treat this disorder
Age is the primary risk factor, but sex also plays a role, with men being 1.5 times more likely than women to develop Parkinson’s
blending environmental and hereditary causes
my father also had it,” recalls Garza
who sought early treatment to prevent more severe symptoms
who has been researching this from a biological heritage perspective for two decades
“the genetic factor is present in 15% of patients with Parkinson’s
and up to 18 genes linked to its development are already known.”
His team at the Institute of Neurology and Neurosurgery at Zambrano-Hellion Hospital is working to identify Latin American genes in patients to improve treatments to combat the disease and anticipate its most debilitating manifestations
“a DNA analysis is being carried out on patients with Parkinson’s to perform a genetic correlation with some clinical signs that appear and to conduct a genetic evaluation with certain markers that appear long before the disease becomes apparent.”
Although this neurological disorder exhibits a wide variety of data in its clinical presentation
the initial manifestation usually begins with a resting tremor
“which first occurs in one limb and then generalizes throughout the body,” the neuroscientist clarifies
Affected individuals also suffer from muscle rigidity in the limbs
“But there can be another 50 non-motor symptoms
and autonomic disorders,” explains Héctor Martínez
some signs appear up to 10 or even 15 years before motor problems
such as a loss of smell or rapid eye movement sleep behavior disorder
often unpleasant dreams with a lot of action during the night
but my wife does remember that I did it often,” confesses Leova Garza
we can predict the future development of the disease in the population and even prevent its worst effects in those we already know to have Parkinson’s,” says Martínez
one of the scientists involved in the search for biomarkers for early diagnosis
and neuropathological data analyzed in studies have shown that the pathology of this condition occurs years before the symptoms appear
tiny regulators of gene expression in Parkinson’s patients
“The levels and content of these microRNAs in patients’ blood can track the disease’s progression,” Martínez says
MicroRNAs have become an attractive non-invasive tool for diagnosing early and monitoring the progression of neurodegenerative diseases
“If we find recurring microRNAs in Parkinson’s patients associated with pre-symptoms
we can intervene before motor symptoms start,” Martínez details
the levels in a patient’s blood and the content of their information can be used to track the course of the disease
“These micro-regulators found in bodily fluids and other extracellular environments
exhibiting a complex cell-to-cell communication mechanism.” This property has positioned them as potential biological indicators
microRNAs have become an attractive non-invasive tool for early diagnosis of neurodegenerative diseases
“If we find forms of microRNA that are repeated in Parkinson’s patients and are related to some of the early signs before the initial presentation of the disease is detected
we can intervene before motor symptoms begin
before more than 50% of the dopaminergic neurons are lost,” Martínez explains
My hands still tremble if I get nervous or angry
I can still drive and draw,” says patient Leova Garza
who did not give up his profession as an architect despite the stark diagnosis he received over a decade ago
the chances of helping the patient and treating them as soon as possible with the available therapies diminish,” notes Martínez
one of the doctors who has been treating him since then
This dopamine precursor helps with movement and coordination
“These drugs work well when combined with physical activity and rehabilitation,” says Martínez
When medications and motor rehabilitation therapies are no longer effective, it’s time to turn to stimulation techniques, explains Fortino Salazar, a neurosurgeon and co-founder of the TecSalud Parkinson’s Center
Since 2000, Salazar’s team has operated on patients with severe, medication-resistant tremors. Annually, about 20 individuals undergo DBS at the center
This technique uses electrical current to regulate brain activity by placing electrodes in the brain and a battery under the chest
“This allows for significant control of rigidity
among other symptoms,” explains Fortino Salazar
who underwent the surgery more than a year ago
“I noticed a 100% difference,” the patient asserts
a significant improvement in the patient’s quality of life is anticipated
and a 50% average reduction in the required medications is expected
the amount of levodopa I was taking increased for it to be effective
But I didn’t want to take so many pills
I reduced them by up to 90% thanks to the surgery!” Garza is grateful for the significant changes he noticed after undergoing Deep Brain Stimulation
“This is a safe therapy that works very well. However, it does not improve all issues, such as walking,” clarifies Eduardo Moraud
This Spanish scientist works at the Swiss Federal Institute of Technology in Lausanne and is one of the world’s leading experts in neuromodulation techniques
Moraud has applied his engineering and robotics expertise to studying the human nervous system
becoming a pioneer in spinal stimulation technologies
“Instead of sending activation to the brain area affected by Parkinson’s
we do not attack the origin of the problem
the output that sends signals to the legs,” explains the research group leader responsible for a historic milestone: enabling a patient with advanced Parkinson’s disease to walk again
This revolutionary technique had already been tested on paraplegic individuals who were unable to take a single step and
regained their ability to walk the day after the operation
the interdisciplinary team led by the Spaniard succeeded in implementing the same type of neuroprosthesis in a Swiss patient who had been living with the disorder for more than 20 years
“He had already undergone deep brain stimulation and other available techniques that improved his symptoms
But there came a point when he no longer responded to therapies and could no longer walk,” explains the scientist
who then came up with the idea of installing two implants in his brain to read thoughts and send them to a third implant to electrically stimulate the spinal cord
After the implementation of his development
“our patient went from falling up to six times a day to at most once a week
In addition to improving his physical condition
he began to feel much more confident,” Moraud details
The revolutionary technology can measure the electrical activity generated by the brain to control spinal stimulation
acting as a digital bridge between the brain and the spine
the brain sends signals to the spinal cord to restore voluntary control
the implant helps us trick the faulty nervous system
manipulating these connections to appropriately stimulate the spinal cord and enable the patient to walk,” explains the engineer
proud of the impact of this historic development
TecSalud successfully incorporated a new technology into DBS in a 65-year-old patient with advanced Parkinson’s
This device sends electrical impulses and detects and corrects altered brain activity
in addition to sending the electrical impulses to the brain
we can detect altered brain activity in patients and correct it in real time
This allows for more precise stimulation and improves the patient’s clinical condition,” explains the neurosurgeon at TecSalud
the only private center in the country that offers the most effective and innovative methods for managing Parkinson’s
positioning itself among the best care centers in the world
“We already have a protocol that we will apply to use Spinal Stimulation in these patients with walking difficulties
such as chronic pain,” explains Fortino Salazar
His team also plans to incorporate another revolutionary development into their services
“This involves high-intensity focused ultrasound
which does not require surgery and is only available in very few places worldwide,” he notes
This innovative treatment uses ultrasound waves to treat debilitating tremors with a non-invasive procedure
“It produces the same effects as deep brain stimulation to improve slowness
Remember that this disorder completely disables daily activities
Everyday tasks that take increasingly longer for those who suffer from it
end up becoming an impossible mission,” says the neurologist
who explains that the course of Parkinson’s on many occasions causes the person to isolate themselves and enter a depression
Leova Garza has worked to alleviate the social effects of the disease he has suffered from for 15 years
I would hide the hand I couldn’t control
I wanted to avoid giving explanations and feeling sorry for myself
I don’t do that anymore,” he reveals
“The social implications of Parkinson’s are immense
the importance of patient care must be under the coordination and experience of a multidisciplinary team
which integrates from neurosurgery specialists to psychologists,” says Martínez
this positions TecSalud as one of the best centers for treating the disease: “The close accompaniment of patients and their families together with the implementation of the most effective and pioneering therapies based on frontier science.”
Although the mechanisms of Parkinson’s still hold many unknowns for medicine
“and there is a long way to go to stop it completely
I do not doubt that we will achieve it soon,” Salazar enthusiastically assures
his team has already achieved that patients like Garza
with more than a decade living with the disorder
can control almost all of its sequelae and
“recover the quality of life thanks to the wonderful care that the entire medical team provided me.”

It’s hard to miss Machetes Doña Leova’s trailer on North Lamar in the parking lot of Austin Appliance Rebuilders
hand-painted lettering proclaiming they have machetes (as well as gorditas
The machetes here are nearly enough to feed two hungry people
as well as the shrimp one that comes with poblano
They also sometimes have birria here as a special - no consome though - but a birria machete is a pretty rare sight to behold (and also a delicious thing to eat)
Mexican
South Austin
Autenticos Michoacaos has a wide menu of tacos
and just about anything else you can fit inside of a tortilla
and the ones here are excellent - full of enough meat and cheese to fill half a dozen (or more) street tacos
They spend enough time on the griddle to really crisp up
getting almost firm enough to rival its namesake tool
but we’re also pretty confident this is a “no wrong answer” situation when it comes to choosing fillings
