Houston-based PolyVascular, which develops minimally invasive solutions for children with congenital heart disease, was named the overall winner of the American Heart Association’s annual Health Tech Competition earlier this month.

The company was founded in 2014 by Dr. Henri Justino and Daniel Harrington and was part of TMCi's 2017 medical device cohort. It is developing the first polymer-based transcatheter pulmonary valve designed specifically for young children, allowing for precise sizing and redilation as the child grows while also avoiding degradation. PolyVascular has completed preclinical studies and is working toward regulatory submissions, an early feasibility study and its first-in-human clinical trial thanks to a recent SBIR grant from the National Heart, Lung, and Blood Institute.

With the new AHA honor, PolyVascular will be invited to join the association’s Center for Health Technology & Innovation Innovators’ Network, which connects entrepreneurs, providers and researchers to share and advance innovation in cardiovascular and brain health.

“This is a tremendous honor for PolyVascular—we’re especially proud to bring hope to families and children living with congenital heart defects,” Justino said in a news release. “Our technology—a minimally invasive valve that can be expanded over time to grow with the child—has the potential to dramatically reduce the need for repeated open-heart surgeries.”

The Health Tech Competition is a live forum for health care innovators to present their digital solutions for treating or preventing cardiovascular diseases and stroke.

Finalists from around the world addressed heart failure, hypertension, congenital heart defects and other issues that exist in cardiovascular, brain and metabolic health. Solutions were evaluated on the criteria of validity, scientific rigor and impact.

The judges included Texas-based Dr. Eric D. Peterson, professor of medicine in the division of cardiology at UT Southwestern Medical Center, and Dr. Asif Ali, clinical associate professor of cardiovascular medicine at the University of Texas Medical School in Houston and director at Cena Research Institute.

According to the American Heart Association, nearly half of U.S. adults live with some form of cardiovascular disease or stroke.

“The American Heart Association plays a pivotal role in advancing innovative care pathways, and we’re excited that our solution aligns with its guidelines and mission,” Justino said in a news release. “It’s time these life-changing technologies reach the youngest patients, just as they already do for adults.”

University of Houston receives funding to support diverse cardiovascular researchers

pumping up innovation

University of Houston professors have received a nearly $800,000 grant to create a new summer program that will support diverse future researchers.

The National Heart, Lung, and Blood Institute provided $792,900 in grant funding to Bradley McConnell, professor of pharmacology at the UH College of Pharmacy, and Tho Tran, research assistant professor of chemistry at the UH College of Natural Sciences and Mathematics.

The funding will go toward created a summer program called the University of Houston Cardiovascular Undergraduate Research Experience, or UH-CURE. Ten undergraduate students per year will be selected for five years in cardiovascular research across disciplinary lines.

"We are so grateful to be able to provide talented students across the U.S. an opportunity to experience our excellent cardiovascular research environment,” Tran says in a news release. “We want UH-CURE participants to gain confidence in their research abilities through our hands-on approach and the skillset to navigate future challenges through our professional training.”

The goal is to increase students’ interest in cardiovascular research, and students have the opportunity to receive a $6,000 stipend, travel to a globally recognized cardiovascular research conference, and take part in on-campus housing and a food allowance. The summer program will also try to develop research skills, increase awareness of transdisciplinary research, promote diversity and collaborations, cultivate transferable skills necessary for succeeding in graduate school and help facilitate undergraduate students to pursue further training in cardiovascular research.

The program will integrate students into a research lab where they will learn research skills, data analysis, and research integrity. The program will be under the mentorship of a faculty member from across UH’s colleges, and include workshop and enrichment activities.

McConnell and Tran previously formed the American Heart Association-funded UH-HEART pilot program, which focused on cardiovascular research. They expanded on that initiative with UH-CURE, which includes cardiovascular research across disciplinary lines from community engagement and population-based research to basic, translational, and applied research. UH-CURE also helps prepare for careers in cardiovascular research.

“We all know that a diverse environment leads to a much better generation of ideas and solutions,” Tran adds. “We hope to bring that strength to the future of cardiovascular research through our students.”

Innovative Houston urban farm scores national award for green work

to the moon

A Houston urban farm has earned national recognition for its innovative approach to water conservation. Moonflower Farms won the American Heart Association's Foodscape Innovation Excellence Award, which recognizes positive changes in the foodscape, a term for all of the places where food is produced, purchased, or consumed.

The Heart Association selected Moonflower's submission, titled "Sustainable Farming Through Water Conservation," from 26 entries. Dallas' Restorative Farms earns the Foodscape Innovation Consumer Choice Award.

"These two innovations demonstrate a way of producing food that promotes affordability and equitable access, and the American Heart Association is proud to recognize these efforts," AHA chief medical officer for prevention Eduardo Sanchez said in a release.

Located in a 20,000-square-foot greenhouse south of downtown, Moonflower operates what it describes as Houston's first vertical indoor farm. The method both reduces the amount of space needed to grow the farm's microgreens, lettuces, herbs and edible flowers and it eliminates the disruptions caused by adverse weather conditions, which allows the farm to produce year round.

Moonflower uses a closed-loop system for capturing rainwater to feed its crops. The water is treated and oxygenated so that it can be reused. Not having to pay for water from the City of Houston allows the farm to operate more economically and sell its produce at an affordable price to restaurants and individuals.

"Our hydroponic farm uses 90-percent less water than conventional farms," Moonflower founder and CEO Federico Marques said in a statement. "We provide year-round produce to residents in historically underserved communities and donate produce to local charitable food systems."

One of those charities is Houston non-profit Second Servings, which "rescues" food from restaurants and events and distributes it to food pantries and other resources.

"The donations we receive from Moonflower Farms are incredible," Second Servings founder and president Barbara Bronstein said. "Their hydroponically grown greens are so appreciated by the needy Houstonians we serve, who lack affordable, convenient access to fresh produce."

Recently, Moonflower introduced a SupaGreens subscription box that allows customers to purchase greens weekly, bimonthly, or monthly. The box is delivered directly to consumers.

Houston team uses CPRIT funding to develop nanodrug for cancer immunotherapy

cancer research

With a relative five-year survival rate of 50 percent, pancreatic cancer is a diagnosis nobody wants. At 60 percent, the prognosis for lung cancer isn’t much rosier. That’s because both cancers contain regulatory B cells (Bregs), which block the body’s natural immunity, making it harder to fight the enemies within.

Newly popular immunotherapies in a category known as STING agonists may stimulate natural cancer defenses. However, they can also increase Bregs while simultaneously causing significant side effects. But Wei Gao, assistant professor of pharmacology at the University of Houston College of Pharmacy, may have a solution to that conundrum.

Gao and her team have developed Nano-273, a dual-function drug, packaged in an albumin-based particle, that boosts the immune system to help it better fight pancreatic and lung cancers. Gao’s lab recently received a $900,000 grant from the Cancer Prevention and Research Institute of Texas (CPRIT) to aid in fueling her research into the nanodrug.

“Nano-273 both activates STING and blocks PI3Kγ—a pathway that drives Breg expansion, while albumin nanoparticles help deliver the drug directly to immune cells, reducing unwanted side effects,” Gao said in a press release. “This approach reduces harmful Bregs while boosting immune cells that attack cancer, leading to stronger and more targeted anti-tumor responses.”

In studies using models of both pancreatic and lung cancers, Nano-273 has shown great promise with low toxicity. Its best results thus far have involved using the drug in combination with immunotherapy or chemotherapy.

With the CPRIT funds, Gao and her team will be able to charge closer to clinical use with a series of important steps. Those include continuing to test Nano-273 alongside other drugs, including immune checkpoint inhibitors. Safety studies will follow, but with future patients in mind, Gao will also work toward improving her drug’s production, making sure that it’s safe and high-quality every time, so that it is eventually ready for trials.

Gao added: “If successful, this project could lead to a new type of immunotherapy that offers lasting tumor control and improved survival for patients with pancreatic and lung cancers, two diseases that urgently need better treatments."

Houston booms as No. 2 U.S. metro for new home construction

Construction Boom

Driven by population growth, more residential rooftops are popping up across Houston and the rest of Texas than anywhere else in America.

Using data from the U.S. Census Bureau and Zillow, Construction Coverage found 65,747 new residential units were authorized in greater Houston in 2024. That figure landed Houston in second place among major metro areas for the total number of housing permits, including those for single-family homes, apartments, and condos.

Just ahead of Houston was the Dallas-Fort Worth Metroplex, which took first place with 71,788 residential permits approved in 2024. In third place was the country’s largest metro, New York City (57,929 permits).Elsewhere in Texas, the Austin metro ranked sixth (32,294 permits), and the San Antonio metro ranked 20th (14,857 permits).

Construction Coverage also sorted major metro areas based on the number of new housing units authorized per 1,000 existing homes in 2024. Raleigh, North Carolina, held the No. 1 spot (28.8 permits per 1,000 existing homes), followed by Austin at No. 2 (28.6), DFW at No. 3 (22.2), Houston at No. 4 (21.6), and San Antonio at No. 13 (13.6).

A Newsweek analysis of Census Bureau data shows building permits for 225,756 new residential units were approved in 2024 in Texas — a trend fueled largely by activity in DFW, Houston, Austin, and San Antonio. That put Texas atop the list of states building the most residential units for the year.

Through the first eight months of last year, 145,901 permits for new residential units were approved in Texas, according to Census Bureau data. That’s nearly 80,000 permits shy of the 2024 total.

Among the states, Construction Coverage ranks Texas sixth for the number of residential building permits approved in 2024 per 1,000 existing homes (17.9).

Extra housing is being built in Texas to meet demand spurred by population growth. From April 2020 to July 2024, the state’s population increased 7.3 percent, the Census Bureau says.

While builders are busy constructing new housing in Texas, they’re not necessarily profiting a lot from homebuilding activity.

“Market conditions remain challenging, with two-thirds of builders reporting they are offering incentives to move buyers off the fence,” North Carolina homebuilder Buddy Hughes, chairman of the National Association of Home Builders, said in a December news release. “Meanwhile, builders are contending with rising material and labor prices, as tariffs are having serious repercussions on construction costs.”
