A collaborative NIH-funded team is using AI to mine common chest CT scans to predict mortality. Their research identified a collection of cardiac factors that were predictive of death in a large group of patients, potentially setting the stage for improved cardiac screening.

NIBIB-supported researchers have developed a smart nanoprobe designed to infiltrate prostate tumors and send back a signal using an optical imaging technique known as Raman spectroscopy. The new probe, evaluated in mice, has the potential to determine tumor aggressiveness and could also enable sequential monitoring of tumors during therapy to quickly determine if a treatment strategy is working.

A multidisciplinary group of NIH-funded scientists have successfully captured real-time, high-resolution images of the developing mouse placenta during the course of pregnancy. Their technique, which combines a surgically implanted window with a next-generation imaging system, provides key insight into placental development under both healthy and pathological conditions.

What if bacteria—which love to grow deep inside tumors—could guide cancer therapies directly to their target? NIH-funded researchers have engineered a bacterial strain to “light up” tumors so that reprogrammed T cells, drawn like a moth to a flame, can find and destroy them. Their preclinical treatment could potentially be effective against any solid tumor type.

A collaborative team of NIH-funded researchers is developing a way to obtain DNA shed from brain tumors using focused ultrasound. Their first-in-human study could be an important step towards improving the way brain tumors are diagnosed.

NIH-funded researchers have outlined a method to print biocompatible structures through thick, multi-layered tissues using focused ultrasound.

Dendritic cells are key orchestrators of the immune response, but most vaccination strategies don’t effectively target them. NIBIB-funded researchers have developed biodegradable nanoparticles that are designed to deliver mRNA cargo to dendritic cells in the spleen. Combined with another type of immunotherapy, their vaccine had robust antitumor effects in multiple mouse models.

Nanozymes—artificial enzymes that can carry out pre-determined chemical reactions—could selectively activate a cancer drug within a tumor while minimizing damage to healthy tissue in a mouse model of triple negative breast cancer.

This fully wireless ultrasound patch, which can capture detailed medical information and wirelessly transmit the data to a smart device, could represent a major step forward in at-home health care technology.

This interview with Maryellen Giger, PhD, delves into the creation of the MIDRC imaging repository, how its data can be used to develop and evaluate AI algorithms, ways that bias can be introduced—and potentially mitigated—in medical imaging models, and what the future may hold.

Researchers from Rice University have created drug-filled microparticles that can be engineered to degrade and release their therapeutic cargo days or weeks after administration. By combining multiple microparticles with different degradation times into a single injection, the researchers could develop a drug formulation that delivers many doses over time.

NIH-funded researchers developed an online tool that can analyze self-collected, at-home videos with a smartphone. When deployed in a nationwide study, the tool could predict physical health and osteoarthritis of the knee or hip.

Researchers at Carnegie Mellon University are developing lipid nanoparticles that are designed to carry mRNA specifically to the pancreas. Their study in mice could pave the way for novel therapies for intractable pancreatic diseases, such as diabetes and cancer.

Bioengineers from Columbia University are developing a pipeline to systematically evaluate how bacterial treatments might synergize with existing anti-cancer therapies in preclinical models.

After years of research, an NIH-funded team has developed a wearable cardiac ultrasound imager that can non-invasively capture real-time images of the human heart. The prototype patch, which is about the size of a postage stamp, can be worn during exercise, providing valuable cardiac information when the heart is under stress.
