A team of Houston researchers has developed a new microfluidic device aimed at making treatments safer for children with hyperleukocytosis, a life-threatening hematologic emergency often seen in patients with leukemia.

Dr. Fong Lam, an associate professor of pediatrics at Baylor College of Medicine and a pediatric intensive care physician at Texas Children’s Hospital, partnered with Sergey Shevkoplyas, a professor of biomedical engineering at UH, on the device that uses a large number of tiny channels to quickly separate blood cells by size in a process called controlled incremental filtration, according to a news release from UH.

They tested whether performing cell separation with a high-throughput microfluidic device could alleviate the limitations of traditional conventional blood-filtering machines, which pose risks for pediatric patients due to their large extracorporeal volume (ECV), high flow rates and tendency to cause significant platelet loss in the patient. The results of their study, led by Mubasher Iqbal, a Ph.D. candidate in biomedical engineering at UH, were published recently in the journal Nature Communications.

“Continuously and efficiently separating leukocytes from recirculating undiluted whole blood — without device clogging and cell activation or damage — has long been a major challenge in microfluidic cell separation,” Shevkoplyas said in a news release. “Our study is the first to solve this problem.”

Hyperleukocytosis is a condition that develops when the body has an extremely high number of white blood cells, which in many cases is due to leukemia. According to the release, up to 20 percent to 30 percent of patients with acute leukemia develop hyperleukocytosis, and this places them at risk for potentially fatal complications.

The new device utilizes tiny channels—each about the width of a human hair—to efficiently separate blood cells through controlled incremental filtration. According to Lam, the team was excited that the new device could operate at clinically relevant flow rates.

The device successfully removed approximately 85 percent of large leukocytes and 90 percent of leukemic blasts from undiluted human whole blood without causing platelet loss or other adverse effects. It also operates with an ECV that’s about 1/70th of conventional leukapheresis machines, which makes it particularly suitable for infants and small children.

“Overall, our study suggests that microfluidics leukapheresis is safe and effective at selectively removing leukocytes from circulation, with separation performance sufficiently high to ultimately enable safe leukapheresis in children,” Shevkoplyas said in the release.

Houston space org to launch experiments aboard first mission into polar orbit

all aboard

Houston's Translational Research Institute for Space Health, or TRISH, will send its latest experiments into space aboard the Fram2 mission, the first all-civilian human spaceflight mission to launch over the Earth’s polar regions.

Fram2, operated by SpaceX, is targeting to launch Monday, March 31, at NASA’s Kennedy Space Center in Florida. The crew of four is expected to spend several days in polar orbit aboard the SpaceX Dragon spacecraft in low Earth orbit. TRISH’s research projects are among 22 experiments that the crew will conduct onboard.

The crew's findings will add to TRISH's Enhancing eXploration Platforms and ANalog Definition, or EXPAND, program and will be used to help enhance human health and performance during spaceflight missions, including missions to the moon and Mars, according to a release from TRISH.

“The valuable space health data that will be captured during Fram2 will advance our understanding of how humans respond and adapt to the stressors of space,” Jimmy Wu, TRISH deputy director and chief engineer and assistant professor in Baylor’s Center for Space Medicine, said in the release. “Thanks to the continued interest in furthering space health by commercial space crews, each human health research project sent into orbit brings us closer to improving crew member well-being aboard future spaceflight missions.”

The six TRISH projects on Fram2 include:

  • Cognitive and Physiologic Responses in Commercial Space Crew on Short-Duration Missions, led by Dr. Mathias Basner at the University of Pennsylvania Perelman School of Medicine. The crew will wear a Garmin smartwatch and a BioIntelliSense BioButton® medical grade device to track cognitive performance, including memory, spatial orientation, and attention before, during, and after the mission.
  • Otolith and Posture Evaluation II, led by Mark Shelhamer at Johns Hopkins University. The experiment will look at how astronauts’ eyes sense and respond to motion before and after spaceflight to better understand motion sickness in space.
  • REM and CAD Radiation Monitoring for Private Astronaut Spaceflight, led by Stuart George at NASA Johnson Space Center. This experiment will test space radiation exposure over the Earth’s north and south poles and how this impacts crew members.
  • Space Omics + BioBank, led by Richard Gibbs and Harsha Doddapaneni at Baylor College of Medicine. The experiment will use Baylor’s Human Genome Sequencing Center's Genomic Evaluation of Space Travel and Research program to gain insights from pre-flight and post-flight samples from astronauts.
  • Standardized research questionnaires, led by TRISH. The test asks a set of standardized research questionnaires for the crew to collect data on their sleep, personality, health history, team dynamics and immune-related symptoms.
  • Sensorimotor adaptation, led by TRISH. The project collects data before and after flight to understand sensorimotor abilities, change and recovery time to inform future missions to the moon.

TRISH, which is part of BCM’s Center for Space Medicine with partners Caltech and MIT, has launched experiments on numerous space missions to date, including Blue Origin's New Shepard rocket last November and Axiom Space's Ax-3 mission to the International Space Station last January.

Houston lab develops AI tool to improve neurodevelopmental diagnoses

developing news

One of the hardest parts of any medical condition is waiting for answers. Speeding up an accurate diagnosis can be a doctor’s greatest mercy to a family. A team at Baylor College of Medicine has created technology that may do exactly that.

Led by Dr. Ryan S. Dhindsa, assistant professor of pathology and immunology at Baylor and principal investigator at the Jan and Dan Duncan Neurological Research Institute at Texas Children’s Hospital, the scientists have developed an artificial intelligence-based approach that will help doctors to identify genes tied to neurodevelopmental disorders. Their research was recently published the American Journal of Human Genetics.

According to its website, Dhindsa Lab uses “human genomics, human stem cell models, and computational biology to advance precision medicine.” The diagnoses that stem from the new computational tool could include specific types of autism spectrum disorder, epilepsy and developmental delay, disorders that often don’t come with a genetic diagnosis.

“Although researchers have made major strides identifying different genes associated with neurodevelopmental disorders, many patients with these conditions still do not receive a genetic diagnosis, indicating that there are many more genes waiting to be discovered,” Dhindsa said in a news release.

Typically, scientists must sequence the genes of many people with a diagnosis, as well as people not affected by the disorder, to find new genes associated with a particular disease or disorder. That takes time, money, and a little bit of luck. AI minimizes the need for all three, explains Dhindsa: “We used AI to find patterns among genes already linked to neurodevelopmental diseases and predict additional genes that might also be involved in these disorders.”

The models, made using patterns expressed at the single-cell level, are augmented with north of 300 additional biological features, including data on how intolerant genes are to mutations, whether they interact with other known disease-associated genes, and their functional roles in different biological pathways.

Dhindsa says that these models have exceptionally high predictive value.

“Top-ranked genes were up to two-fold or six-fold, depending on the mode of inheritance, more enriched for high-confidence neurodevelopmental disorder risk genes compared to genic intolerance metrics alone,” he said in the release. “Additionally, some top-ranking genes were 45 to 500 times more likely to be supported by the literature than lower-ranking genes.”

That means that the models may actually validate genes that haven’t yet been proven to be involved in neurodevelopmental conditions. Gene discovery done with the help of AI could possibly become the new normal for families seeking answers beyond umbrella terms like “autism spectrum disorder.”

“We hope that our models will accelerate gene discovery and patient diagnoses, and future studies will assess this possibility,” Dhindsa added.

Rice, MD Anderson receive $1.5 million to further brain cancer research

fresh funding

Rice University chemist Han Xiao, who also serves as director of the university’s Synthesis X Center, and cancer biologist Dihua Yu of The University of Texas MD Anderson Cancer Center have received a three-year, $1.5 million grant from the Robert J. Kleberg Jr. and Helen C. Kleberg Foundation.

The funding will allow them to continue their research on treating brain metastasis by overcoming the blood-brain barrier, or the BBB, according to a news release.

Brain metastasis is the leading form of brain cancer, with survival rates below 20 percent within a year of diagnosis, according to the National Library of Medicine. It commonly originates from breast, lung and melanoma cancers.

The BBB typically acts as a protective barrier for the brain. However, it prevents most drugs from being able to directly reach the brain. According to Rice, only 2 percent of FDA-approved small molecule drugs can penetrate the BBB, limiting treatment options.

Xiao and Yu’s approach to dealing with the BBB includes a light-induced brain delivery (LIBD) platform. The advanced system employs nanoparticles that are embedded with a near-infrared dye for the transport of therapeutic agents across the BBB. The research will evaluate the LIBD’s ability to improve the delivery of small-molecule drugs and biological therapies. Some therapies have shown potential for reducing cancer growth in laboratory studies, but they have struggled due to limited BBB penetration in animal models.

“Our LIBD platform represents a novel strategy for delivering drugs to the brain with precision and efficiency,” Xiao said in a news release. “This technology could not only improve outcomes for brain metastasis patients but also pave the way for treating other neurological diseases.”

The Kleberg Foundation looks for groundbreaking medical research proposals from leading institutions that focus on “innovative basic and applied biological research that advances scientific knowledge and human health” according to the foundation.

“This research is a testament to the power of collaboration and innovation,” Xiao said in a news release. “Together, we’re pushing the boundaries of what’s possible in treating brain metastasis and beyond.”

Rice launched the Synthesis X Center, or Synth X, last spring. It was born out of what started about eight years ago as informal meetings between Xiao's research group and others from the Baylor College of Medicine’s Dan L Duncan Comprehensive Cancer Center. It aims to turn fundamental research into clinical applications through collaboration.

“This collaboration builds on the strengths of both research teams,” Xiao said in the release. “By combining SynthX Center's expertise in chemistry with Dr. Yu's expertise in cancer biology and brain metastases, we aim to create a transformative solution.”

Texas institute grants $12M to bring leading cancer researchers to Houston

cha-ching

Rice University has recruited a prominent Swedish cancer researcher thanks to a $6 million grant from the Cancer Prevention and Research Institute of Texas.

It’s among $68 million in research grants recently awarded by the state agency, and six recruitment grants totaling $16 million to bring leading cancer researchers to Texas.

A news release from the Cancer Prevention and Research Institute of Texas (CPRIT) describes Pernilla Wittung-Stafshede of the Chalmers University of Technology in Gothenburg, Sweden, as “an accomplished and highly gifted biophysical scientist tackling complicated biological questions regarding the role of metals and metal dysregulation in various diseases. She pioneered a new research field around the role of metal ions in the folding and function of metalloproteins.”

Metalloproteins account for nearly half of all proteins in biology, according to the National Institutes of Health. They “catalyze some of the most difficult and yet important functions in [nature], such as photosynthesis and water oxidation,” the federal agency says.

Wittung-Stafshede, a professor of chemical biology and life sciences at Chalmers, is a former professor at Rice.

Aside from the money for Wittung-Stafshede, Houston recruitment grants also went to:

  • University of Texas M.D. Anderson Cancer Center: $2 million to recruit Rosalie Griffin of the Mayo Clinic
  • Baylor College of Medicine: $2 million to recruit Dr. Nipun Verma of the Yale University School of Medicine
  • Baylor College of Medicine: $2 million to recruit Xin “Daniel” Gao of Harvard University and the Massachusetts Institute of Technology

In Houston, cancer research grants were given to:

  • Baylor College of Medicine: $7.8 million
  • M.D. Anderson Cancer Center: $20.7 million
  • Rice University: $ 1 million
  • University of Houston: $1.2 million
  • University of Texas Health Science Center at Houston: $4.5 million

“The awards … represent the depth and diversity of CPRIT funding for cancer research in Texas,” says Kristen Doyle, CEO of CPRIT. “These grants develop new approaches to preventing, diagnosing, treating, and surviving cancer for all Texans.”

Houston researchers make headway on affordable, sustainable sodium-ion battery

Energy Solutions

A new study by researchers from Rice University’s Department of Materials Science and NanoEngineering, Baylor University and the Indian Institute of Science Education and Research Thiruvananthapuram has introduced a solution that could help develop more affordable and sustainable sodium-ion batteries.

The findings were recently published in the journal Advanced Functional Materials.

The team worked with tiny cone- and disc-shaped carbon materials from oil and gas industry byproducts with a pure graphitic structure. The forms allow for more efficient energy storage with larger sodium and potassium ions, which is a challenge for anodes in battery research. Sodium and potassium are more widely available and cheaper than lithium.

“For years, we’ve known that sodium and potassium are attractive alternatives to lithium,” Pulickel Ajayan, the Benjamin M. and Mary Greenwood Anderson Professor of Engineering at Rice, said in a news release. “But the challenge has always been finding carbon-based anode materials that can store these larger ions efficiently.”

Lithium-ion batteries traditionally rely on graphite as an anode material. However, traditional graphite structures cannot efficiently store sodium or potassium energy, since the atoms are too big and interactions become too complex to slide in and out of graphite’s layers. The cone and disc structures “offer curvature and spacing that welcome sodium and potassium ions without the need for chemical doping (the process of intentionally adding small amounts of specific atoms or molecules to change its properties) or other artificial modifications,” according to the study.

“This is one of the first clear demonstrations of sodium-ion intercalation in pure graphitic materials with such stability,” Atin Pramanik, first author of the study and a postdoctoral associate in Ajayan’s lab, said in the release. “It challenges the belief that pure graphite can’t work with sodium.”

In lab tests, the carbon cones and discs stored about 230 milliamp-hours of charge per gram (mAh/g) by using sodium ions. They still held 151 mAh/g even after 2,000 fast charging cycles. They also worked with potassium-ion batteries.

“We believe this discovery opens up a new design space for battery anodes,” Ajayan added in the release. “Instead of changing the chemistry, we’re changing the shape, and that’s proving to be just as interesting.”

FAA demands investigation into SpaceX's out-of-control Starship flight

Out of this world

The Federal Aviation Administration is demanding an accident investigation into the out-of-control Starship flight by SpaceX on May 27.

Tuesday's test flight from Texas lasted longer than the previous two failed demos of the world's biggest and most powerful rocket, which ended in flames over the Atlantic. The latest spacecraft made it halfway around the world to the Indian Ocean, but not before going into a spin and breaking apart.

The FAA said Friday that no injuries or public damage were reported.

The first-stage booster — recycled from an earlier flight — also burst apart while descending over the Gulf of Mexico. But that was the result of deliberately extreme testing approved by the FAA in advance.

All wreckage from both sections of the 403-foot (123-meter) rocket came down within the designated hazard zones, according to the FAA.

The FAA will oversee SpaceX's investigation, which is required before another Starship can launch.

CEO Elon Musk said he wants to pick up the pace of Starship test flights, with the ultimate goal of launching them to Mars. NASA needs Starship as the means of landing astronauts on the moon in the next few years.

TMC med-tech company closes $2.5M series A, plans expansion

fresh funding

Insight Surgery, a United Kingdom-based startup that specializes in surgical technology, has raised $2.5 million in a series A round led by New York City-based life sciences investor Nodenza Venture Partners. The company launched its U.S. business in 2023 with the opening of a cleanroom manufacturing facility at Houston’s Texas Medical Center.

The startup says the investment comes on the heels of the U.S. Food and Drug Administration (FDA) granting clearance to the company’s surgical guides for orthopedic surgery. Insight says the fresh capital will support its U.S. expansion, including one new manufacturing facility at an East Coast hospital and another at a West Coast hospital.

Insight says the investment “will provide surgeons with rapid access to sophisticated tools that improve patient outcomes, reduce risk, and expedite recovery.”

Insight’s proprietary digital platform, EmbedMed, digitizes the surgical planning process and allows the rapid design and manufacturing of patient-specific guides for orthopedic surgery.

“Our mission is to make advanced surgical planning tools accessible and scalable across the U.S. healthcare system,” Insight CEO Henry Pinchbeck said in a news release. “This investment allows us to accelerate our plan to enable every orthopedic surgeon in the U.S. to have easy access to personalized surgical devices within surgically meaningful timelines.”

Ross Morton, managing Partner at Nodenza, says Insight’s “disruptive” technology may enable the company to become “the leader in the personalized surgery market.”

The startup recently entered a strategic partnership with Ricoh USA, a provider of information management and digital services for businesses. It also has forged partnerships with the Hospital for Special Surgery in New York City, University of Chicago Medicine, University of Florida Health and UAB Medicine in Birmingham, Alabama.
