Novel method uses lasers to carve paths inside biocompatible gels

Future medicine is bound to include extensive tissue-engineering technologies such as organs-on-chips and organoids - miniature organs grown from stem cells. But all this is predicated on a simple yet challenging task: controlling cellular behavior in three dimensions.

New nano-fabricated platform provides accurate post-surgery prognosis for glioblastoma patients

A new nano-fabricated platform for observing brain cancer cells provides a much more detailed look at how the cells migrate and a more accurate post-surgery prognosis for brain cancer (glioblastoma) patients.

New effort in biomedical engineering may improve heart repair

Jianyi "Jay" Zhang, M.D., Ph.D., brought his biomedical engineering expertise to the University of Alabama at Birmingham to fix hearts.

Researchers discover how specific gene inhibits bacterial invasion of colonic epithelia

A group of researchers at Osaka University elucidated how a gene named Ly6/Plaur domain containing 8 (Lypd8) inhibits bacterial invasion of colonic epithelia, regulating intestinal inflammation. This achievement may lead to the development of drugs for ulcerative colitis.

New bio-mimicry method allows scientists to track cells in vivo using MRI during preclinical, clinical trials

Researchers led by Carnegie Mellon University Professor of Biological Sciences Chien Ho have developed a new method for preparing mesenchymal stem cells (MSCs) that not only leads to the production of more native stem cells, but also labels them with a FDA approved iron-oxide nanoparticle (Ferumoxytol).

Scientists identify new hots pots of antibiotic resistance

Antibiotic-resistant bacteria most often are associated with hospitals and other health-care settings, but a new study indicates that chicken coops and sewage treatment plants also are hot spots of antibiotic resistance.

New method may help identify small amounts of nanomaterials in environment samples

It is still unclear what the impact is on humans, animals and plants of synthetic nanomaterials released into the environment or used in products. It's very difficult to detect these nanomaterials in the environment since the concentrations are so low and the particles so small. Now the partners in the NanoUmwelt project have developed a method that is capable of identifying even minute amounts of nanomaterials in environmental samples.

Researchers develop new technique to study blood vessel inflammation

Nanotechnology has led to better diagnostic techniques and more effective treatments for a variety of illnesses. Tiny devices measuring between 1 and 100 micrometers--one micrometer is equal to one millionth of a meter--enable scientists to observe cell activity and deliver drugs to individual cells--a breakthrough that is on the verge of revolutionizing precision medicine for treatment of diseases such as cancer.

Neuroscientists decipher new pathway in stem cell differentiation

How do neurons become neurons? They all begin as stem cells, undifferentiated and with the potential to become any cell in the body.Until now, however, exactly how that happens has been somewhat of a scientific mystery. New research conducted by UC Santa Barbara neuroscientists has deciphered some of the earliest changes that occur before stems cells transform into neurons and other cell types.

New type of nerve cells appears to control feeding behaviors in mice

While researching the brain's learning and memory system, scientists at Johns Hopkins say they stumbled upon a new type of nerve cell that seems to control feeding behaviors in mice. The finding, they report, adds significant detail to the way brains tell animals when to stop eating and, if confirmed in humans, could lead to new tools for fighting obesity. Details of the study will be published by the journal Science on March 18.

Study: Statin drugs can reduce time to clear tuberculosis infection in mice

In a study using mice, the Johns Hopkins University School of Medicine infectious disease experts have added to evidence that statin drugs — known primarily for their cholesterol-lowering effects — can significantly reduce the time it takes to clear tuberculosis infection.

Modified protein appears to reverse liver fibrosis, cirrhosis in rats

A protein modified to increase the amount of time it circulates in the bloodstream appears to reverse liver fibrosis and cirrhosis in rats, according to results of a study led by Johns Hopkins researchers.

ONR researcher explores how explosive shock waves contribute to traumatic brain injury

Today's warfighters are outfitted with body armor strong enough to withstand shrapnel from a bomb or other explosive device. One debilitating threat from a blast, however, is a force they can't see--the explosive shock wave itself.

New TAU study suggests potential therapeutic pathway to keep osteosarcoma lesions dormant

Osteosarcoma is a cancer that develops in the bones of children and adolescents. It is one of the most aggressive cancers, with only a 15 per cent, five-year survival rate when diagnosed in an advanced metastatic stage. There are approximately 800 new cases diagnosed each year in the US, and no viable treatments.

UCSF study finds specific molecular-genetic mechanism that links sleep and seasonal depression

A newly discovered human gene mutation appears to contribute both to unusual sleep patterns and to heightened rates of seasonal depression, according to new research from UC San Francisco.
