Largest survey on genetic, epigenetic stability of stem cells

An international study, published today in the prestigious journal Nature Biotechnology, reveals more about human pluripotent stem cells and their genetic stability and has important implications for the development of therapies using these cells.

Counterparts of memory cells ward off microbial foes

The immune system possesses a type of cell that can be activated by tissues within the body to remind the immune system not to attack our own molecules, cells and organs, UCSF researchers have discovered.

New glycoconjugate vaccine prototype more effective than traditional vaccines

Brigham and Women's Hospital (BWH) researchers have created a vaccine that is more potent than traditional vaccines available today. The glycoconjugate vaccine prototype is 100 times more effective than traditional glycoconjugate vaccines. Their work is published in the December 2011 issue of Nature Medicine.

UIC recruiting volunteers for study on effectiveness of vitamin D in addition to asthma medication

Researchers at the University of Illinois at Chicago are recruiting volunteers with asthma for a study of whether taking vitamin D can make asthma medication more effective.

Blood stem cells engineered to create cancer-killing T-cells

Researchers from UCLA's cancer and stem cell centers have demonstrated for the first time that blood stem cells can be engineered to create cancer-killing T-cells that seek out and attack a human melanoma. The researchers believe this approach could be useful in 40 percent of Caucasians with this malignancy.

Growth hormone replacement increases bone formation in abdominally obese women

In a new study presented today at the annual meeting of the Radiological Society of North America (RSNA), growth hormone replacement for six months was found to increase bone formation in abdominally obese women.

Seizure drug slows spread of uveal melanoma

A drug commonly used to treat seizures appears to make eye tumors less likely to grow if they spread to other parts of the body, according to researchers at Washington University School of Medicine in St. Louis.

Study reveals underlying molecular mechanism contributing to development of lymphomagenesis

Researchers from the NYU Cancer Institute, an NCI-designated cancer center at NYU Langone Medical Center, have discovered a new potential therapeutic target for Diffuse Large B-Cell Lymphoma (DLBCL), the most aggressive and common type of lymphoma in adults.

More neural connecting pathways in the language network than originally thought

While it has long been recognized that certain areas in the brain's left hemisphere enable us to understand and produce language, scientists are still figuring out exactly how those areas divvy up the highly complex processes necessary to comprehend and produce language.

Fungi and bacteria help one another stay mobile

Bacteria and fungi are remarkably mobile. Now researchers at Tel Aviv University have discovered that the two organisms enjoy a mutually beneficial relationship to aid them in that movement - and their survival.

Scientists identify cellular protein that plays central role in formation of new blood vessels

Scientists at the University of North Carolina at Chapel Hill School of Medicine have identified a cellular protein that plays a central role in the formation of new blood vessels.

Scientists seek to prove beta oscillations of the cortex

Before she could seek to convince the world that her computer model of a key brain circuit explains a fundamental, 80-year-old mystery of neuroscience with potential relevance to Parkinson's disease, Stephanie Jones sought to convince Christopher Moore.

Scientists use genetic methods to successfully repair cleft lips in mice embryos

Scientists at Weill Cornell Medical College used genetic methods to successfully repair cleft lips in mice embryos specially engineered for the study of cleft lip and cleft palate. The research breakthrough may show the way to prevent or treat the conditions in humans.

New database for scientists researching fission yeast

A new database promises to be an invaluable resource to scientists who use a unique single-celled fungus to study human diseases.

Sensorimotor experience influences brain’s linking of signals from different senses

Over the years pianists develop a particularly acute sense of the temporal correlation between the movements of the piano keys and the sound of the notes played. However, they are no better than non-musicians at assessing the synchronicity of lip movements and speech.

Serotonin instructs scar forming cells to switch off regeneration in chronic liver disease

In liver disease, extent of tissue damage depends on the balance between the generation of scar tissue and the regeneration of new liver cells. In a significant minority of people who get injury to their organs instead of repairing them, they form scars.

New compound circumvents drug-efflux pumps associated with Gram-positive bacteria

It's no wonder that medicine's effort to combat bacterial infections is often described as an arms race. When new drugs are developed to combat infections, the bacterial target invariably comes up with a deterrent.

Bone cell factor can lull prostate tumor cells to sleep

Prostate tumor cells can be lulled to sleep by a factor released by bone cells, according to a study published online this week in the Journal of Experimental Medicine. Disease recurs in up to half of prostate cancer patients after treatment, often as a result of metastases that spread to distant organs.

Beta blockers prevent negative effects of stress

Stressed people fall into habits and their behaviour is not goal-directed. That the neurotransmitter norepinephrine plays a decisive role here is now reported in the Journal of Neuroscience by scientists from Bochum led by Dr. Lars Schwabe (RUB Faculty of Psychology).

NIH awards $3.2M for development of highly efficient system of generating nucleic acid molecules

The National Institutes of Health (NIH) has awarded $3.2 million to a team of preeminent engineering, chemistry, and biology researchers to develop a highly efficient system of generating nucleic acid molecules, called aptamers.
