Protein reduces toxicity of drug-delivery material made of graphene oxide

Posted by in categories: biotech/medical, chemistry, nanotechnology

A new publication has discovered ways to reduce the toxicity of graphene oxide (GO), an ultra-thin sheet of nanomaterial derived from graphite, laying the groundwork to use it as a drug delivery system.

Professor Khuloud Al-Jamal, who led the study, said: “Researchers have been incredibly excited in the potential medical applications of graphene since experiments into the nanomaterial were recognised with the Nobel Prize in Physics in 2010. However, concerns around toxicity have remained a consistent obstacle.”

Graphene oxide (GO) is an ultra-thin sheet derived from graphite. It is similar to pencil lead but includes attached oxygen atoms, making it compatible with water. Its unique physical and chemical properties mean it has a high capacity for carrying antibiotics and anticancer drugs, among others, as well as targeting specific cells, making it a potentially effective drug delivery system.

Wobbly molecules get a closer look

Posted by in categories: biotech/medical, nanotechnology, robotics/AI

While new technologies, including those powered by artificial intelligence, provide innovative solutions to a steadily growing range of problems, these tools are only as good as the data they’re trained on. In the world of molecular biology, getting high-quality data from tiny biological systems while they’re in motion – a critical step for building next-gen tools – is something like trying to take a clear picture of a spinning propeller. Just as you need precise equipment and conditions to photograph the propeller clearly, researchers need advanced techniques and careful calculations to measure the movement of molecules accurately.

Matthew Lew, associate professor in the Preston M. Green Department of Electrical & Systems Engineering in the McKelvey School of Engineering at Washington University in St. Louis, builds new imaging technologies to unravel the intricate workings of life at the nanoscale. Though they’re incredibly tiny – 1,000 to 100,000 times smaller than a human hair – nanoscale biomolecules like proteins and DNA strands are fundamental to virtually all biological processes.

Scientists rely on ever-advancing microscopy methods to gain insights into these systems work. Traditionally, these methods have relied on simplifying assumptions that overlook some complexities of molecular behavior, which can be wobbly and asymmetric. A new theoretical framework developed by Lew, however, is set to shake up how scientists measure and interpret wobbly molecular motion.

Sheba Study: AI Can Spot Patients At Risk Of Pulmonary Embolism

Posted by in categories: biotech/medical, information science, robotics/AI

A newly published study by Sheba Medical Center, Israel’s largest and internationally ranked hospital, shows that AI analysis of medical records as patients are admitted to the ER can accurately identify those at high risk of pulmonary embolism (PE).

A pulmonary embolism is a sudden blockage in an artery in the lung caused by a blood clot, most commonly due to a dislodged clot in the leg. They are normally diagnosed during a CT scan.

Using machine learning, the researchers trained an algorithm to detect a pulmonary embolism before a patient was hospitalized, based on existing medical records.

Custom Implants on Demand? Bandages for the Heart? 3D Printing Method Makes It Possible

Posted by in categories: 3D printing, biotech/medical

University of Colorado at Boulder News

In the quest to develop life-like materials to replace and repair human body parts, scientists face a formidable challenge: Real tissues are often both strong and stretchable and vary in shape and size.

A CU Boulder-led team, in collaboration with researchers at the University of Pennsylvania, has taken a critical step toward cracking that code. They’ve developed a new way to 3D print material that is at once elastic enough to withstand a heart’s persistent beating, tough enough to endure the crushing load placed on joints, and easily shapable to fit a patient’s unique defects.

Metformin and the TAME trial: a conversation with Nir Barzilai and Brad Stanfield

Posted by in categories: biotech/medical, health

In this interview, hosted by Nicolás Cherñavsky, Nir Barzilai and Brad Stanfield discuss metformin, whether or not to use it in non-diabetic patients to slow aging, and the TAME trial.

Nir Barzilai is president of the Academy of Health and Lifespan Research (https://www.ahlresearch.org/), and Brad Stanfield is a primary care physician in Auckland (New Zealand) and runs a YouTube channel (/ @drbradstanfield) with around 250,000 subscribers to explore the latest research and preventive care guidelines.

Breakthrough molecule reverses Alzheimer’s symptoms

Posted by in categories: biotech/medical, health, neuroscience

In a new study, a molecule identified and synthesized by UCLA Health researchers was shown to restore cognitive functions in mice with symptoms of Alzheimer’s disease by effectively jumpstarting the brain’s memory circuitry.

If proven to have similar effects in humans, the candidate compound would be novel among Alzheimer’s disease treatments in its ability to revitalize memory and cognition, study authors said.

There is really nothing like this on the market or experimentally that has been shown to do this.
