Injectable Bandage Targets Fatal Internal Bleeding

National Institute of Biomedical Imaging and Bioengineering

Products are available to quickly seal surface wounds, but rapidly stopping fatal internal bleeding has proven more difficult. Now, biomedical engineers at Texas A&M University are developing an injectable hydrogel bandage that could save lives in emergencies such as penetrating shrapnel wounds on the battlefield.

Device Captures Vesicles Shed by Brain Tumors, Offering Patient-Specific Diagnosis and Treatment

National Institute of Biomedical Imaging and Bioengineering

Bioengineers have developed micro-technologies that capture extracellular vesicles (EVs) released by brain tumors. The vesicles carry samples of the mutated genetic material and proteins causing malignancy that researchers can analyze to optimize precision cancer treatment.

Turning the Light Switch on to Treat Chronic Pain

National Institute of Biomedical Imaging and Bioengineering

Chronic bladder pain affects millions with abdominal discomfort that increases as their bladder fills, causing excessive urinary urgency and frequency. Neuroscientists used optogenetics in experiments with mice to switch on and off the neurons that signal bladder pain.

Biology, Geometry Unite to Thwart Common Cardiovascular Diseases

National Institute of Biomedical Imaging and Bioengineering

To treat cardiovascular disease, surgery can remove blockages in large vessels in the heart or legs but is not possible in small vessels. To address this problem, researchers designed 3D-printed patches seeded with vessel-inducing endothelial cells. In a mouse model of hindlimb ischemia, the researchers identified specific patch patterns that induced growth of organized, tissue-saving blood vessels, demonstrating the potential for the novel technology to address this significant public health problem.

Alternative MRI Contrast Agent Performs Well in NIH Study

National Institute of Biomedical Imaging and Bioengineering

NIH-supported researchers at Massachusetts General Hospital are studying an alternative to current contrast agents used for magnetic resonance imaging. In a recent study, they showed that the experimental alternative, which is a manganese-based compound, performs as well as approved contrast agents. Their study appeared online Nov. 15, 2017, in Radiology.
