New paper describes unique process that is central to induction of MSRA antibiotic resistance

A new paper by a team of University of Notre Dame researchers that included Shahriar Mobashery, Jeffrey Peng, Brian Baker and their researchers Oleg Borbulevych, Malika Kumararasiri, Brian Wilson, Leticia Llarrull, Mijoon Lee, Dusan Hesek and Qicun Shi describes a unique process that is central to induction of antibiotic resistance in the problematic bacterium methicillin-resistant Staphylococcus aureus.

Animals burn protein during long, cold hibernation

When Arctic ground squirrels are getting ready to hibernate they don't just get fat - they pack on muscle at a rate that would make a bodybuilder jealous. And they do it without suffering the harmful effects that high levels of testosterone and other anabolic steroids usually cause. University of Toronto Scarborough (UTSC) researchers have started to untangle how the squirrels manage it, and their results could someday have implications for human health.

Researchers identify molecular pathway that may play key role in evolution of chemotherapy resistance

For patients with ovarian cancer and their physicians, resistance to chemotherapy is a serious concern. However, researchers at Moffitt Cancer Center have identified a molecular pathway that may play a key role in the evolution of chemotherapy resistance.

Scientists discover new type of spinal cord stem cell

A group led by a University of British Columbia and Vancouver Coastal Health scientist has discovered a type of spinal cord cell that could function as a stem cell, with the ability to regenerate portions of the central nervous system in people with spinal cord injuries, multiple sclerosis or amyotrophic lateral sclerosis.

Loop-mediated Isothermal Amplification test for human African trypanosomiasis

The Geneva-based not-for-profit foundation FIND and Japanese diagnostics company Eiken announced today that a next-generation molecular test designed specifically for sleeping sickness - a deadly parasitic disease also known as human African trypanosomiasis (HAT) - is ready to enter accelerated field trials in sites across the Democratic Republic of Congo and Uganda.

Study examines effects of carbon nanoparticles on living cells

A study by researchers from the schools of science and medicine at Indiana University-Purdue University Indianapolis examines the effects of carbon nanoparticles (CNPs) on living cells. This work is among the first to study concentrations of these tiny particles that are low enough to mimic the actual exposure of an ordinary individual.

U of C researchers create new model of obsessive-compulsive disorder

A new model of obsessive-compulsive disorder (OCD) that mirrors both symptoms of the disease and the timing of its treatment in humans has been created by University of Chicago researchers, according to a new study.

New cell type could play an important role in spinal cord injury and disease

The Allen Institute for Brain Science announced today the discovery of a new class of cells in the spinal cord that act like neural stem cells, offering a fresh avenue in the search for therapies to treat spinal cord injury and disease.

UNC-45A protein plays critical role in breast cancer cell division and migration

Researchers have found that a protein linked to cell division and migration and tied to increased cell proliferation in ovarian tumors is also present at high levels in breast cancer specimens and cell lines. The protein, dubbed "UNC-45A," was also determined to be more active in breast cancer cells than in normal breast cells.

New nanopore sensor can lead to early detection of lung cancer

When lung cancer strikes, it often spreads silently into more advanced stages before being detected. In a new article published in Nature Nanotechnology, biological engineers and medical scientists at the University of Missouri reveal how their discovery could provide a much earlier warning signal.

Azithromycin gel may treat borreliosis in humans

Blood-sucking ticks are not just a nuisance, they can also transmit dangerous diseases. One of them is Lyme disease, which is caused by bacteria of the genus Borrelia, and requires a course of treatment with antibiotics lasting several weeks. LMU researchers have come up with a quicker alternative.

Researchers identify promising new therapies for ependymoma

Researchers have identified promising new therapies for ependymoma, a rare tumor with few treatment options. St. Jude Children's Research Hospital investigators led the effort, which used a new, faster drug development system that combines the latest drug screening technology with the first accurate animal model of the tumor.
