Houston researchers tap into tech to provide new brain-related health care solutions

research roundup

Research, perhaps now more than ever, is crucial to expanding and growing innovation in Houston — and it's happening across the city right under our noses.

In InnovationMap's latest roundup of research news, three Houston institutions are working on brain-related health care solutions thanks to technologies.

University of Houston research team focused on brain injury treatment through computation

A University of Houston researcher is tapping into technology to better treat brain injuries and conditions that scientists have not yet figured out treatment for. Badri Roysam, the current chair of electrical and computer engineering at UH and a Hugh Roy and Lillie Cranz Cullen University Professor, and his team have created a new computational image analysis methods based on deep neural networks.

"We are interested in mapping and profiling unhealthy and drug-treated brain tissue in unprecedented detail to reveal multiple biological processes at once - in context," Roysam says in a UH press release about his latest paper published in Nature Communications. "This requires the ability to record high-resolution images of brain tissue covering a comprehensive panel of molecular biomarkers, over a large spatial extent, e.g., whole-brain slices, and automated ability to generate quantitative readouts of biomarker expression for all cells."

Roysam's system, which was developed at the the National Institute of Neurological Disorders and Stroke, analyzes the images on UH's supercomputer automatically and can reveal multiple processes at once – the brain injury, effects of the drug being tested and the potential side effects of the drug, per the release.

"Compared to existing screening techniques, using iterative immunostaining and computational analysis, our methods are more flexible, scalable and efficient, enabling multiplex imaging and computational analysis of up to 10 – 100 different biomarkers of interest at the same time using direct or indirect IHC immunostaining protocols," says Roysam in the release.

The open-source toolkit, which was developed thanks to a $3.19 million grant from the National Institute of Health, is also adaptable to other tissues.

"We are efficiently overcoming the fluorescence signal limitations and achieving highly enriched and high-quality source imagery for reliable automated scoring at scale," says Roysam. "Our goal is to accelerate system-level studies of normal and pathological brains, and pre-clinical drug studies by enabling targeted and off-target drug effects to be profiled simultaneously, in context, at the cellular scale."

Houston Methodist and Rice University launch new collaboration to use robotics for clinical solutions

Rice University and Houston Methodist have teamed up to create a new partnership and to launch the Center for Translational Neural Prosthetics and Interfaces in order to bring together scientists, clinicians, engineers, and surgeons to solve clinical problems with neurorobotics.

"This will be an accelerator for discovery," says the new center's co-director, Dr. Gavin Britz, chair of the Houston Methodist Department of Neurosurgery, in a news release. "This center will be a human laboratory where all of us — neurosurgeons, neuroengineers, neurobiologists — can work together to solve biomedical problems in the brain and spinal cord. And it's a collaboration that can finally offer some hope and options for the millions of people worldwide who suffer from brain diseases and injuries."

The center will have representatives from both Rice and Houston Methodist and also plans to hire three additional engineers who will have joint appointments at Houston Methodist and Rice.

"The Rice Neuroengineering Initiative was formed with this type of partnership in mind," says center co-director Behnaam Aazhang, Rice's J.S. Abercrombie Professor of Electrical and Computer Engineering, who also directs the neuroengineering initiative. "Several core members, myself included, have existing collaborations with our colleagues at Houston Methodist in the area of neural prosthetics. The creation of the Center for Translational Neural Prosthetics and Interfaces is an exciting development toward achieving our common goals."

The team will have a presence on the Rice campus with 25,000 square feet of space in the Rice Neuroengineering Initiative laboratories and experimental spaces in the university's BioScience Research Collaborative. The space at Houston Methodist is still being developed.

"This partnership is a perfect blend of talent," says Rice's Marcia O'Malley, a core member of both the new center and university initiative. "We will be able to design studies to test the efficacy of inventions and therapies and rely on patients and volunteers who want to help us test our ideas. The possibilities are limitless."

Mehmet Orman, assistant professor of chemical and biomolecular engineering at the University of Houston Cullen College of Engineering has been honored with a Faculty Early Career Development Award from the National Science Foundation. The award comes with a $500,000 grant to study persister cells — cells that go dormant and then become tolerant to extraordinary levels of antibiotics.

"Nearly all bacterial cultures contain a small population of persister cells," says Orman in a news release. "Persisters are thought to be responsible for recurring chronic infections such as those of the urinary tract and for creating drug-resistant mutants."

Previously, Orman developed the first methods to directly measure the metabolism of persister cells. He also developed cell sorting strategies to segregate persisters from highly heterogeneous bacterial cell populations, and, according to the release, he will be using his methods in the NSF research project.

Houston researchers collaborate on oral cancer innovation

Two Houston researchers — chemist and bioengineer Jeffrey Hartgerink at Rice University and Dr. Simon Young at the University of Texas Health Science Center at Houston — have again teamed up to advance their previous development of a sophisticated hydrogel called STINGel. This time, they are using it to destroy oral cancer tumors.

SynerGel combines a pair of antitumor agents into a gel that can be injected directly into tumors. Once there, the gel controls the release of its cargo to not only trigger cells' immune response but also to remove other suppressive immune cells from the tumor's microenvironment. The duo reported on the technology in the American Chemical Society journal ACS Biomaterials Science & Engineering.

SynerGel, combines a pair of antitumor agents into a gel that can be injected directly into tumors, where they not only control the release of the drugs but also remove suppressive immune cells from the tumor's microenvironment.

"We are really excited about this new material," Hartgerink says in a news release. "SynerGel is formulated from a specially synthesized peptide which itself acts as an enzyme inhibitor, but it also assembles into a nanofibrous gel that can entrap and release other drugs in a controlled fashion.

In 2018, the pair published research on the use of a multidomain peptide gel — the original STINGel — to deliver ADU-S100, an immunotherapy drug from a class of "stimulator of interferon gene (STING) agonists."

The research is supported by the Oral and Maxillofacial Surgery Foundation, the National Institutes of Health, the Welch Foundation, the National Science Foundation and the Mexican National Council for Science and Technology.

Here are 3 breakthrough innovations coming out of research at Houston institutions

Research Roundup

Research, perhaps now more than ever, is crucial to expanding and growing innovation in Houston — and it's happening across the city right under our noses.

In InnovationMap's latest roundup of research projects, we look into studies on robotics advancing stroke patient rehabilitation, the future of opioid-free surgery, and a breakthrough in recycling plastics.

The University of Houston's research on enhancing stroke rehabilitation

A researcher at the University of Houston has seen positive results on using his robotics on stroke survivors for rehabilitation. Jose Luis Contreras-Vidal, director of UH's Non-Invasive Brain Machine Interface Systems Laboratory, recently published the results of the clinical trial in the journal NeuroImage: Clinical.

The testing proved that most patients retained the benefits for at least two months after the therapy sessions ended, according to a press release from UH, and suggested even more potential in the long term. The study equipped stroke survivors who have limited movement in one arm with a computer program that captures brain activity to determine the subject's intentions and then works with a robotic device affixed to the affected arm, to move in response to those intentions.

"This is a novel way to measure what is going on in the brain in response to therapeutic intervention," says Dr. Gerard Francisco, professor and chair of physical medicine and rehabilitation at McGovern Medical School at The University of Texas Health Science Center at Houston and co-principal investigator, in the release.

"This study suggested that certain types of intervention, in this case using the upper robot, can trigger certain parts of brain to develop the intention to move," he continues. "In the future, this means we can augment existing therapy programs by paying more attention to the importance of engaging certain parts of the brain that can magnify the response to therapy."

The trial was funded by the National Institute of Neurological Disorders and Stroke and Mission Connect, part of the TIRR Foundation. Contreras-Vidal is working on a longer term project with a National Science Foundation grant in order to design a low-cost system that would allow people to continue the treatments at home.

"If we are able to send them home with a device, they can use it for life," he says in the release.

Baylor College of Medicine's work toward opioid-free surgery

In light of a national opioid crisis and more and more data demonstrating the negative effects of the drugs, a Baylor College of Medicine orthopedic surgeon has been working to offer opioid-free surgery recovery to his patients.

"Thanks to a number of refinements, we are now able to perform hip and knee replacements, ranging from straightforward to very complex cases, without patients requiring a single opioid pill," says Dr. Mohamad Halawi, associate professor and chief quality officer in the Joseph Barnhart Department of Orthopedic Surgery, in a press release.

"Pain is one of patients' greatest fears when undergoing surgery, understandably so," Halawi continues. "Today, most patients wake up from surgery very comfortable. Gone are the days of trying to catch up with severe pain. It was a vicious cycle with patients paying the price in terms of longer hospitalization, slower recovery and myriad adverse events."

Halawi explains that his work focuses on preventative measures ahead of pain occurring as well as cutting out opioids before surgery.

"Opioid-free surgery is the way of the future, and it has become a standard of care in my practice," he says. "The ability to provide safer and faster recovery to all patients regardless of their surgical complexity is gratifying. I want to make sure that pain is one less thing for patients to worry about during their recovery."

Rice University's breakthrough on recycling plastics

Houston scientists has found a new use for an otherwise useless byproduct that comes from recycling plastics. Rice University chemist James Tour has discovered that turbostratic graphene flakes can be produced from pyrolyzed plastic ash, and those flakes can then be added to other substances like films of polyvinyl alcohol that better resist water in packaging and cement paste and concrete, as well as strengthen the material.

"This work enhances the circular economy for plastics," Tour says in a press release. "So much plastic waste is subject to pyrolysis in an effort to convert it back to monomers and oils. The monomers are used in repolymerization to make new plastics, and the oils are used in a variety of other applications. But there is always a remaining 10% to 20% ash that's valueless and is generally sent to landfills.

Tour's research has appeared in the journal Carbon. The co-authors of the study include Rice graduate students Jacob Beckham, Weiyin Chen and Prabhas Hundi and postdoctoral researcher Duy Xuan Luong, and Shivaranjan Raghuraman and Rouzbeh Shahsavari of C-Crete Technologies. The National Science Foundation, the Air Force Office of Scientific Research and the Department of Energy supported the research.

"Recyclers do not turn large profits due to cheap oil prices, so only about 15% of all plastic gets recycled," said Rice graduate student Kevin Wyss, lead author of the study. "I wanted to combat both of these problems."

These are the latest COVID-19-focused research projects happening at Houston institutions

research roundup

Researchers across the Houston area are working on COVID-19 innovations every day, and scientists are constantly finding new ways this disease is affecting humankind.

From a COVID breathalyzer to a new collaboration in Houston — here's your latest roundup of local coronavirus research news.

A&M System to collaborate on a COVID-19 breathalyzer

Researchers at Texas A&M University System are collaborating on a new device that uses artificial intelligence in a breathalyzer situation to detect whether individuals should be tested for COVID-19. The technology is being developed through a collaboration with Dallas-based company, Worlds Inc., and the U.S. Air Force.

The device is called Worlds Protect and a patient can use a disposable straw to blow into a copper inlet. In less than a minute, test results can be sent to the person's smartphone. Worlds Inc. co-founders Dave Copps and Chris Rohde envision Worlds Protect kiosks outside of highly populated areas to act as a screening process, according to a news release.

"People can walk up and, literally, just breathe into the device," says Rohde, president of Worlds Inc., in the release. "It's completely noninvasive. There's no amount of touching. And you quickly get a result. You get a yay or nay."

The university system has contributed $1 million in the project's development and is assisting Worlds Inc. with engineering and design, prototype building and the mapping of a commercial manufacturing process. According to the release, the plan was to test the prototypes will be tried out this fall on the Texas A&M campus.

"Getting tech innovations to market is one of our sweet spots," says John Sharp, chancellor of the Texas A&M System, in the release. "This breakthrough could have lasting impact on global public health."

Baylor College of Medicine researchers to determine cyclosporine’s role in treating hospitalized COVID-19 patients

The Baylor College of Medicine has launched a randomized clinical trial to look into how the drug cyclosporine effects the prevention of disease progression in pre-ICU hospitalized COVID-19 patients. The drug has been used for about 40 years to prevent rejection of organ transplants and to treat patients with rheumatoid arthritis and psoriasis.

"The rationale is strong because the drug has a good safety profile, is expected to target the body's hyperimmune response to COVID and has been shown to directly inhibit human coronaviruses in the lab," says Dr. Bryan Burt, chief of thoracic surgery in the Michael E. DeBakey Department of Surgery at Baylor, says in a press release.

Burt initiated this trial and BCM is the primary site for the study, with some collaboration with Brigham and Women's. The hypothesis is that the drug will help prevent the cytokine storm that patients with COVID-19 experience that causes their health to decline rapidly, according to the release.

The study, which is funded by Novartis, plans to enroll 75 hospitalized COVID-19 patients at Baylor St. Luke's Medical Center who are not in the ICU. There will be an initial evaluation at six months but Burt expects to have the final study results in one year.

Rice launches expert group to help guide pandemic response

Rice University is collaborating with other Houston institutions to create the Biomedical Expert Panel, supported by Texas Policy Lab, to assist officials in long-term pandemic recovery.

"Not all agencies and decision-makers have an in-house epidemiologist or easy access to leaders in infectious disease, immunology and health communications," says Stephen Spann, chair of the panel and founding dean of the University of Houston College of Medicine, in a news release. "This panel is about equity. We must break out of our knowledge siloes and face this challenge together, with a commitment to inclusivity and openness."

The purpose of the panel is to be available as a free resource to health departments, social service agencies, school districts and other policymakers. The experts will help design efficient public health surveillance plans, advise on increasing testing capacity and access for underserved communities, and more.

"The precise trajectory of the local epidemic is difficult to predict, but we know that COVID-19 will continue to be a long-term challenge," says E. Susan Amirian, an epidemiologist who leads the TPL's health program, in the release. "Although CDC guidelines offer a good foundation, there is no one-size-fits-all approach when managing a crisis of this magnitude across diverse communities with urgent needs."

3 research innovations in health care to know about in Houston

Research roundup

Researchers across the world are coming up with innovative breakthroughs regarding the coronavirus, but Houston research institutions are also making health and wellness discoveries outside of COVID-19.

Here are three research innovations from Houston scientists from a new cardiac medical device to artificial intelligence-driven predictive technology for cirrhosis patients.

University of Houston's new implantable cardiac device

Cardiac implants and devices like pacemakers are either made with rigid materials that don't do the moving, beating heart any favors or the devices are made with soft materials but sacrifice the quality of information collected.

Researchers led by Cunjiang Yu, a University of Houston professor of mechanical engineering, have reported in Nature Electronics a new rubbery patch designed to collect electrophysiological activity, temperature, heartbeat and other indicators, while being flexible against the heart.

Yu, who is also a principal investigator with the Texas Center for Superconductivity at UH, is the author of the paper says it's the first time a device has both been flexible and accurate. The device, which generates energy from heart beats and doesn't need an external power source, can both collect information from multiple locations on the heart — also known as spatiotemporal mapping — but it can also offer therapeutic benefits such as electrical pacing and thermal ablation, according to the researchers.

"Unlike bioelectronics primarily based on rigid materials with mechanical structures that are stretchable on the macroscopic level, constructing bioelectronics out of materials with moduli matching those of the biological tissues suggests a promising route towards next-generational bioelectronics and biosensors that do not have a hard–soft interface for the heart and other organs," the researchers wrote. "Our rubbery epicardial patch is capable of multiplexed ECG mapping, strain and temperature sensing, electrical pacing, thermal ablation and energy harvesting functions."

Yu has worked on the development of fully rubbery electronics with sensing and other biological capabilities, including for use in robotic hands, skins and other devices.

Baylor College of Medicine's new tool to predict outcomes of cirrhosis

Currently, the standard of care for cirrhosis patients is limited because physicians can't accurately predict long-term outcomes. But this might be changing thanks to researchers at Baylor College of Medicine, the Michael E. DeBakey Veteran's Affairs Medical Center, and the Center for Innovations in Quality, Effectiveness and Safety (IQuESt).

According to their study are published in JAMA Network Open, the researchers developed a model using a blend of artificial intelligence and traditional statistical methods to produce a score better predicting mortality in cirrhosis.

"When we see patients in the clinic we want to guide them about their long-term outcomes. We wanted to create a tool using machine learning and artificial intelligence to improve the accuracy of prognosis, while maintaining ease of use in the clinic," says Dr. Fasiha Kanwal, the author of the study and professor of medicine and section chief of gastroenterology at Baylor, in a news release.

The scientists used data collected from patients at 130 hospitals and clinics — such as demographics, comorbidities, underlying risk factors and severity of liver disease — as well as comprehensive laboratory tests and medication data to create three different statistical models to predict risk of mortality.

"Machine learning and artificial intelligence is important. It did help us find the right risk factors to use, but we didn't need to use very complex models to get there. We were able to create the CiMM score that will work easier in the clinic and is more predictive of mortality than the existing method," says Kanwal.

The Cirrhosis Mortality Model (CiMM) performed the best and most accurately and was more predictive than the current prognostic model, known as the Model for End Stage Liver Disease with sodium (MELD-Na).

"This tool could make a big difference in providing patient-centered care. The CiMM score could be reassessed every time a patient comes into the clinic," Kanwal said. "Previously, we were unable to predict anything long term. But the CiMM score could give us an idea of how to manage disease for one, two and three years out."

UTHealth's $11 million grant to study multi-drug resistant infection factors

A program at the University of Texas Health Science Center at Houston has received an $11 million grant from the National Institute of Allergy and Infectious Diseases to conduct this five-year study on why some critically ill patients develop multidrug-resistant infections.

The Dynamics of Colonization and Infection by Multidrug-Resistant Pathogens in Immunocompromised and Critically Ill Patients will enroll patients at both Memorial Hermann Hospital-Texas Medical Center and The University of Texas MD Anderson Cancer Center.

According to a news release, the research team will seek to explain the microbial, clinical, and antimicrobial resistance factors of three major multidrug-resistant pathogens: Vancomycin-resistant enterococci, Enterobacterales producing extended spectrum β-lactamases/carbapenemases, and Clostridioides difficile. Note: all three pathogens are resistant to antimicrobial treatment such as antibiotics.

"We want to learn more about how these three classes of organisms colonize the gastrointestinal tract of critically ill patients and, eventually, cause infections in these patient populations," says Dr. Cesar A. Arias, the study's principal investigator and professor of infectious disease at McGovern Medical School at UTHealth.

University of Houston engineer's research hopes to help detect cancer cells faster and easier

future of health

Early stage cancer is hard to detect, mostly because traditional diagnostic imaging cannot detect tumors smaller than a certain size. One Houston innovator is looking to change that.

Wei-Chuan Shih, professor of electrical and computer engineering at the University of Houston's Cullen College of Engineering, recently published his findings in IEEE Sensors journal. According to a news release from UH, the cells around cancer tumors are small — ~30-150nm in diameter — and complex, and the precise detection of these exosome-carried biomarkers with molecular specificity has been elusive, until now.

"This work demonstrates, for the first time, that the strong synergy of arrayed radiative coupling and substrate undercut can enable high-performance biosensing in the visible light spectrum where high-quality, low-cost silicon detectors are readily available for point-of-care application," says Shih in the release. "The result is a remarkable sensitivity improvement, with a refractive index sensitivity increase from 207 nm/RIU to 578 nm/RIU."

What Shih has done is essentially restored the electric field around nanodisks, providing accessibility to an otherwise buried enhanced electric field. Nanodisks are antibody-functionalized artificial nanostructures which help capture exosomes with molecular specificity.

"We report radiatively coupled arrayed gold nanodisks on invisible substrate (AGNIS) as a label-free (no need for fluorescent labels), cost-effective, and high-performance platform for molecularly specific exosome biosensing. The AGNIS substrate has been fabricated by wafer-scale nanosphere lithography without the need for costly lithography," says Shih in the release.

This process speeds up screening of the surface proteins of exosomes for diagnostics and biomarker discovery. Current exosome profiling — which relies primarily on DNA sequencing technology, fluorescent techniques such as flow cytometry, or enzyme-linked immunosorbent assay (ELISA) — is labor-intensive and costly. Shih's goal is to amplify the signal by developing the label-free technique, lowering the cost and making diagnosis easier and equitable.

"By decorating the gold nanodisks surface with different antibodies (e.g., CD9, CD63, and CD81), label-free exosome profiling has shown increased expression of all three surface proteins in cancer-derived exosomes," said Shih. "The sensitivity for detecting exosomes is within 112-600 (exosomes/μL), which would be sufficient in many clinical applications."

High-tech art exhibit pops up alongside Houston innovation hub

immersive art

A traveling art immersion experience has officially opened its doors in Houston. The tech-enabled show picked a particularly innovative spot, too.

The new "Immersive Van Gogh Exhibit Houston," opened Thursday, October 14, at Lighthouse Artspace Houston, a converted, 16,500-square-foot warehouse space (1314 Brittmore Rd.) directly next to The Cannon's West Houston innovation and entrepreneurial hub in The Founders District. The show has sold more than 3 million tickets sold nationwide, the show has outsold Taylor Swift.

Not to be confused with the current Van Gogh interactive offering, this stunning — and original — show animates some of the most iconic works for Van Gogh, who is considered one of humanity's most important and notable artists.

Equally a star player in the production is the music, some by Italian composer Luca Longobardi, along with a classic from Edith Piaf, and even a tune from Radiohead lead singer Thom Yorke.

Masterpieces come alive via some 60,600 frames of video, totaling 90,000,000 pixels and more than 500,000 cubic feet of projections. But as anyone who's studied the master's works can attest, that detail is necessary to truly capture his creations.

Giant walls dance with images of workers in fields, which then wipe to floral settings, or memorable imagery from Van Gogh's instantly recognizable pieces such as Mangeurs de Pommes de Terre (The Potato Eaters, 1885), Les Tournesols (Sunflowers,1888), La Chambre à coucher (The Bedroom, 1889), and the unforgettable Nuit étoilée (Starry Night, 1889).

Even the floor — lined with circles to stand or sit on for social distancing — is a piece of art. Visitors can stroll (highly recommended), space permitting, or sit, awash in Van Gogh's dreamscape.

"It's really interesting you comment that this could be Van Gogh's dream," Vito Iaia, co-founder of Impact Museums and the event's co-producer, tells CultureMap. "This is what Massimiliano Siccardi, the protection artist who created the work you see on the walls, believes went through Van Gogh's head — right before he died."

Part art exhibit, part animated film, "Immersive Van Gogh Exhibit Houston" marries the work of three different artists: Van Gogh (of course), aforementioned projection artist Siccardi, and Rowan Doyle, the creative director who created the scenic elements surrounding the venue.

Those scenic elements include:

  • Sunflower pickup truck: A vintage Ford truck, parked outside the venue, gets a splash of sunflower yellow.
  • Van Gogh Chapel: Meant to be a love letter to Houston and specifically Rothko Chapel, this design is meant to be a contemplative space before entering the main gallery.
  • Van Gogh Timeline: As the name implies, this installation features pivotal moments of Van Gogh's career, with symbols harking to his short life.
  • Texas sunflower sign: Sunflowers dot the Texas state display, perfect for IG selfies.

A bar and gift shop also add to the experience.

At once stirring, playful, and poignant — even emotional — the experience is fitting for now, despite the artwork dating back to the late 1800s.

"People ask why Massimiliano chose Van Gogh right now," says Iaia. "And part of the answer is there's probably no better time to tell Van Gogh's story than right now. This is a reflection of what he went through as a troubled soul and the struggles people are going through today."

But it's not all dark. "The bright side is, this is a great way to remember his work. The reception has been amazing. It's giving him a new life."

Prepare for a serene, honest moment, but don't be surprised to be affected — especially with the final imagery. "People are driven to joys, or tears, or thought," says Iaia. I had someone come out and say, 'I just saw God.'"
