Novavax reports positive preclinical results for H1N1 influenza VLP vaccine

Novavax, Inc. (Nasdaq: NVAX) announced positive preclinical results with Novavax's 2009 novel H1N1 influenza virus-like particle (VLP) vaccine. The study, conducted by scientists from Novavax and the Centers for Disease Control and Prevention (CDC) based in Atlanta, GA, under a collaborative agreement, represents the first efficacy report of a 2009 novel H1N1 vaccine in ferrets. The ferret model is widely accepted to be the most appropriate animal model for evaluating influenza disease and vaccines. Novavax scientists designed the vaccine using recombinant virus like particles (VLP) technology against an H1N1 virus strain (A/California/04/2009) isolated in the beginning of the 2009 H1N1 outbreak.

Research study highlights the biological importance of Vitamin D in humans and other primates

A new study has concluded that one key part of the immune system, the ability of vitamin D to regulate anti-bactericidal proteins, is so important that is has been conserved through almost 60 million years of evolution and is shared only by primates, including humans - but no other known animal species.

Brain's motor and perception regions disconnected in tone-deaf people

Nerve fibers that link perception and motor regions of the brain are disconnected in tone-deaf people, according to new research in the August 19 issue of The Journal of Neuroscience. Experts estimate that at least 10 percent of the population may be tone deaf - unable to sing in tune. The new finding identifies a particular brain circuit that appears to be absent in these individuals.

Researchers reveal new ways to detect the hidden biases of medical research

A study by researchers at the University of Leicester has revealed new ways to spot whether medical research has hidden biases. Writing in the prestigious British Medical Journal, Santiago Moreno and his colleagues demonstrate how to spot 'publication bias' in the reporting of clinical trials which potentially form the basis of Government and NHS health policies.

New understanding on meningitis cause

A specific protein on the surface of a common bacterial pathogen allows the bacteria to leave the bloodstream and enter the brain, initiating the deadly infection known as meningitis. The new finding, which may guide development of improved vaccines to protect those most vulnerable, including young infants and the elderly, is now available online in the Journal of Experimental Medicine.

Fatigue during radiotherapy for breast or prostate cancer may be caused by inflammation

Patients who experience fatigue during radiotherapy for breast or prostate cancer may be reacting to activation of the proinflammatory cytokine network, a known inflammatory pathway, according to a report in Clinical Cancer Research, a journal of the American Association for Cancer Research.

Discovery of key factor that stimulates brain cancer cells to spread

Researchers funded by the National Institutes of Health have found that the activity of a protein in brain cells helps stimulate the spread of an aggressive brain cancer called glioblastoma multiforme (GBM). In a move toward therapy, the researchers showed that a small designer protein can block this activity and reduce the spreading of GBM cells grown in the laboratory.

Custom-tailored anti-cancer drugs

Cancer remains a deadly threat despite the best efforts of science. New hopes were raised a few years ago with the discovery that the uncontrolled growth of cancer cells could be thwarted by blocking the action of proteasomes. Biochemists at the Technische Universitaet Muenchen (TUM) have illuminated a reaction pathway that does just that, in collaboration with researchers from Nereus Pharmaceuticals, based in San Diego, California. In the current issue of the Journal of Medicinal Chemistry, they report insights that could potentially lead to the development of custom-tailored anti-cancer drugs.

Nonsurgical, quick and accurate test for diagnosing endometriosis discovered

A quick and accurate test for endometriosis that does not require surgery has been developed by researchers from Australia, Jordan and Belgium, according to new research published online today (Wednesday 19 August) in Europe's leading reproductive medicine journal Human Reproduction.

Clinically depressed individuals show reduced brain function

Clinically depressed individuals are less capable of finding pleasure in activities they previously enjoyed, a recent study has proven. Research featured in the August 26 issue of the NeuroReport shows reduced brain function in the reward center of the brain in depressed individuals, when compared to healthy subjects.

Study shows lower short-term mortality rates in patients hospitalized for AMI

From 1995 to 2006, hospital 30-day death rates decreased significantly for Medicare patients hospitalized for a heart attack, as did the variation in the rate between hospitals, according to a study in the August 19 issue of JAMA.

Neurofeedback 'brain training' helps surgeons improve skills

A team of researchers have found that trainee eye surgeons can significantly improve their surgical skills by regulating their own brainwave activity, using a process called neurofeedback.

Texas Heart Institute receives $4.1 million to determine the effect of pulseless blood flow on bodily functions

The National Institutes of Health (NIH) has awarded a $4.1 million grant to the Texas Heart Institute at St. Luke’s Episcopal Hospital (THI at SLEH) to determine the effect of pulseless blood flow on bodily functions. This knowledge will be used in the development of a total artificial heart (TAH) that produces continuous, pulseless blood flow.

Mediterranean-type diet and exercise lowers Alzheimer's risk

Both being more physically active and adhering to a Mediterranean-type diet appears to be associated with reduced Alzheimer's risk, according to a new report in the August 12, 2009 issue of the Journal of the American Medical Association (JAMA).

Disrupting the DNA-repair process

Scientists at Dana-Farber Cancer Institute have uncovered the mechanism behind a promising new approach to cancer treatment: damaging cancer cells' DNA with potent drugs while simultaneously preventing the cells from repairing themselves.

Novel genome-analysis strategy to speed search for gene-disease links

University of Washington (UW) researchers have successfully developed a novel genome-analysis strategy for more rapid, lower cost discovery of possible gene-disease links. By saving time and lowering expenses, the approach makes it feasible for scientists to search for disease-causing genes in people with the same inherited disorder but without any family ties to each other.
