ALS damages neurons in parts of the brain responsible for cognition and behaviour

Recently published studies by a researcher in the Faculty of Medicine & Dentistry demonstrate that ALS - known as Lou Gehrig's disease - damages neurons in parts of the brain responsible for cognition and behaviour.

Reducing levels of protein FKBP51 may yield new antidepressant therapies

Decreasing expression of a protein associated with susceptibility to depression made old mice resistant to depressive-like behavior while improving their hormonal response to stress, a study led by researchers at the University of South Florida found. The lack of this protein, FKBP51, did not adversely affect their memory, learning, or basic motor functions.

Additional data on safety, tolerability of Cempra's solithromycin to be presented at 51st ICAAC

Cempra Pharmaceuticals today announced abstracts to be presented on its fourth generation macrolide and novel fluoroketolide antibiotic, solithromycin (CEM-101), at the 51st Interscience Conference on Antimicrobial Agents and Chemotherapy (ICAAC), September 17 to 20, 2011, in Chicago. The abstracts provide additional data that demonstrate the safety and routes of administration of CEM-101, a new generation macrolide.

New insight into how nervous system regulates immunity

Scientists have identified a surprising new role for a new type of T cell in the immune system: some of them can be activated by nerves to make a neurotransmitter (acetylcholine) that blocks inflammation. The discovery of these T cells is novel and suggests that it may be possible to treat inflammation and autoimmune diseases by targeting the nerves and the T cells. The study was published this week in Science.

Researchers show how protein fortilin promotes growth of cancer cells

Researchers have shown for the first time that the protein fortilin promotes growth of cancer cells by binding to and rendering inert protein p53, a known tumor suppressor. This finding by researchers at the University of Texas Medical Branch may lead to treatments for a range of cancers and atherosclerosis, which p53 also helps prevent, and appears in the current print issue of the Journal of Biological Chemistry.

Good absorption of calcium linked to prostate cancer

A study by epidemiologists at Wake Forest Baptist Medical Center and colleagues suggests that a high intake of calcium causes prostate cancer among African-American men who are genetically good absorbers of the mineral.

Study reveals altered digestive genes in children with autism and gastrointestinal disturbances

Researchers at the Center for Infection and Immunity (CII) at Columbia University's Mailman School of Public Health and at the Harvard Medical School report that children with autism and gastrointestinal disturbances have altered expression of genes involved in digestion. These variations may contribute to changes in the types of bacteria in their intestines.

Vesicular stomatitis virus kills cancer cells

In a new project, researchers from LIFE - the Faculty of Life Sciences at the University of Copenhagen - document that the vesicular stomatitis virus (VSV) plays a previously unknown dual role in the prevention of a number of cancers. The new findings show that the virus both kills cancer cells and stops the expression of the molecules which certain types of cancer cells produce to hide from the immune system.

Adult stem cells hold hope for treatment of lupus

With a patient's own adult stem cells, there is new hope for the intractable autoimmune disease lupus - systemic lupus erythematosus (SLE) - which is difficult to cure.

Chemical composition of chitosan influences antibacterial activity

The polysaccharide (sugar substance) chitosan has a documented antibacterial effect. Hilde Mellegård's doctoral research shows that this antibacterial activity varies according to the chemical composition of the chitosan.

Researchers discuss how decision neuroscience hopes to advance understanding of brain

Although still a young field, research in "decision neuroscience" has exploded in the last decade, with scientists beginning to decipher what exactly is happening in our brains when we are making choices, whether big or small.

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.
