Researchers settle controversy over the mechanism by which silver nanoparticles kill bacteria

Rice University researchers have settled a long-standing controversy over the mechanism by which silver nanoparticles, the most widely used nanomaterial in the world, kill bacteria.

Physiologists, neuropathologists identify origin of cancer metastasis formation

It is not primary tumors that are responsible for the majority of cancer deaths, but rather their metastases. Physiologists and neuropathologists from the University of Zurich have now identified the origin of metastasis formation, thereby becoming the first to reveal the pathway of metastasizing intestinal cancer cells out of the blood stream. The results allow new approaches in the development of cancer therapies.

SRI receives NIAID grant to develop HIV vaccine

The Scripps Research Institute has been awarded a grant expected to total more than $77 million from the National Institutes of Health's (NIH) National Institute of Allergy and Infectious Diseases (NIAID).

New assay can identify rare cancerous cells within mixed populations

Rare cells can be identified within mixed cell populations with near perfect accuracy using a detection technique devised by research teams led by Robert Wieder, MD, PhD, at the University of Medicine and Dentistry of New Jersey-New Jersey Medical School and Rajan Kumar, MD, PhD, at Genome Data Systems in Hamilton, N.J. This technique may facilitate cancer diagnosis, which often relies on the detection of rare cancerous cells in tiny amounts of biopsy tissue or fluid.

Study details how resistance to targeted drug therapy emerges in colorectal cancers

A Harvard researcher studying the evolution of drug resistance in cancer is predicting that, in a few decades, "many, many cancers could be manageable."

Study links brain anatomy and activation with human altruism

What can explain extreme differences in altruism among individuals, from Ebenezer Scrooge to Mother Teresa? It may all come down to variation in the size and activity of a brain region involved in appreciating others' perspectives, according to a study published by Cell Press in the July 12th issue of the journal Neuron. The findings also provide a neural explanation for why altruistic tendencies remain stable over time.

Novel molecular mechanism responsible for most important symptom of major depression

Stanford University School of Medicine scientists have laid bare a novel molecular mechanism responsible for the most important symptom of major depression: anhedonia, the loss of the ability to experience pleasure.

Genes responsible for immune function are almost different in middle age than in early adulthood

Important insights that explain why our ability to ward off infection declines with age are published in a new research report in the July 2012 issue of the Genetics Society of America's journal, GENETICS.

Powerful brain chemical systems work together to paralyze skeletal muscles during REM sleep

Two powerful brain chemical systems work together to paralyze skeletal muscles during rapid eye movement (REM) sleep, according to new research in the July 11 issue of The Journal of Neuroscience. The finding may help scientists better understand and treat sleep disorders, including narcolepsy, tooth grinding, and REM sleep behavior disorder.

Brain anatomy and brain activity connected to altruistic behavior

The volume of a small brain region influences one's predisposition for altruistic behavior. Researchers from the University of Zurich show that people who behave more altruistically than others have more gray matter at the junction between the parietal and temporal lobe, thus showing for the first time that there is a connection between brain anatomy, brain activity and altruistic behavior.

Naturally occurring molecule may prevent plaque buildup inside arteries

Cleveland Clinic researchers have discovered that a naturally occurring molecule may play a role in preventing plaque buildup inside arteries, possibly leading to new plaque-fighting drugs and improved screening of patients at risk of developing atherosclerosis.

Oligodendroglia cells: An interview with Jeffrey Rothstein

There are three principle cells in the brain: neurons and two types of glial cells. One type is called an astrocyte. These were well known to inactivate neurotransmitters like glutamate, and provide metabolic support to neurons.

Research into “insulating” brain cells could help to cure neurodegenerative diseases such as ALS

Johns Hopkins researchers say they have discovered that the central nervous system's oligodendroglia cells, long believed to simply insulate nerves as they "fire" signals, are unexpectedly also vital to the survival of neurons. Damage to these insulators appears to contribute to brain injury in neurodegenerative diseases such as amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease for the Yankee baseball great who died from the disease.

Courtagen launches nucSEEKPDx assay

Courtagen Life Sciences, Inc., a privately held life sciences company that provides innovative proteomic and genomic products and services to the life sciences industry, today announced the expansion of their genetic test menu. The new genetic test, nucSEEKPDx, will sequence approximately 1,100 nuclear genes constituting the mitochondrial exome, which encodes the vast majority of proteins found in the mitochondrion. This test is by far the most comprehensive test on the market for the management of mitochondrial disorders.

Neonate blood-brain barrier more intact than adults following stroke

The ability for substances to pass through the blood-brain barrier is increased after adult stroke, but not after neonatal stroke, according to a new study the UCSF that will be published July 11 in the Journal of Neuroscience.

PROLOR to present data on long-acting clotting factors for hemophilia at WFH World Congress

PROLOR Biotech, Inc., announced that the company will present data today on its long-acting clotting factors for the treatment of hemophilia at the World Federation of Hemophilia (WFH) World Congress.

Breast cancer drug bevacizumab slows progression but has no overall survival benefit

The cancer drug bevacizumab (Avastin®) offers only a modest benefit in prolonging disease progression in patients with advanced stage breast cancer, according to a systematic review by Cochrane researchers. The researchers assessed the efficacy of bevacizumab in combination with chemotherapy, an established cancer treatment in this indication, and found no overall survival benefit when adding bevacizumab to chemotherapy.

Study details development of first mouse model for Usher syndrome III

A new study published in the July 11 issue of the Journal of Neuroscience details the development of the first mouse model engineered to carry the most common mutation in Usher syndrome III causative gene (Clarin-1) in North America.

Microbiologists reveal how T. brucei’s key proteins organize to replicate its mtDNA

A group of diseases that kill millions of people each year can't be touched by antibiotics, and some treatment is so harsh the patient can't survive it. They're caused by parasites, and for decades researchers have searched for a "magic bullet" to kill them without harming the patient. Now, a team of microbiologists at the University of Massachusetts Amherst has made an advance that could one day lead to a new weapon for fighting parasitic diseases such as African sleeping sickness, chagas disease and leishmaniasis.
