New protein fragments identified for anthrax vaccine development

Researchers at Albert Einstein College of Medicine of Yeshiva University have identified two small protein fragments that could be developed into an anthrax vaccine that may cause fewer side effects than the current vaccine.

The 2009 H1N1 influenza virus causes more severe disease than human seasonal influenza viruses

Preliminary findings in ferrets suggest that the novel 2009 H1N1 influenza virus may outcompete human seasonal influenza viruses, researchers say. Tests in animals showed that levels of the 2009 H1N1 virus rose more quickly than levels of the seasonal virus strains, and the new virus caused more severe disease. In line with previous findings by other research groups, the University of Maryland researchers also observed that the novel H1N1 virus was transmitted more easily from infected to uninfected ferrets than either of the two seasonal influenza viruses.

Alcohol consumption disrupts circadian rhythm in humans

Chronic alcohol consumption blunts the biological clock's ability to synchronize daily activities to light, disrupts natural activity patterns and continues to affect the body's clock (circadian rhythm), even days after the drinking ends, according to a new study with hamsters.

Mitoxantrone is highly efficient in suppressing multiple sclerosis

According to data supplied by the German Multiple Sclerosis Society's national MS register (DMSG - Deutsche Multiple Sklerose Gesellschaft), up to 10% of German MS patients have been treated with mitoxantrone in the past few years.

Iowa researchers modify siRNA for impacting targeted cells in cancer treatment

Small interfering RNA (siRNA), a type of genetic material, can block potentially harmful activity in cells, such as tumor cell growth. But delivering siRNA successfully to specific cells without adversely affecting other cells has been challenging.

Lakewood-Amedex to speed up development of its broad spectrum anti-influenza product into clinical studies

Lakewood-Amedex Inc., (L-A), the anti-infectives biopharmaceutical company developing a unique portfolio of anti-bacterial and anti-viral products including NuBiotics, a novel family of synthetic anti-bacterial compounds, and anti-viral products against hepatitis, HIV and influenza, announced today that it is accelerating development of its broad spectrum anti-influenza product into clinical studies.

New technique for diabetes treatment may be in the offing

An exploration of the molecular links between insulin resistance and inflammation may have revealed a novel target for diabetes treatment, say scientists at the John G. Rangos Sr. Research Center, Children's Hospital of Pittsburgh of UPMC. Their findings were published earlier this month in the online version of Diabetes, one of the journals of the American Diabetes Association.

DAS181 inhibits H5N1 Influenza lung virus infection of human lung tissues

NexBio, Inc. announced today the publication "DAS181 Inhibits H5N1 Influenza Lung Virus Infection of Human Lung Tissues" in the September, 2009 issue of the journal Antimicrobial Agents and Chemotherapy (AAC).

Thick blood to cause or prevent strokes and heart attacks proved by scientists

"Thick" blood can cause heart attack and stroke, but also prevent them. Scientists at Heidelberg University Hospital have explained the mechanism of this clinical paradox for the first time on an animal model. Mice with a greater tendency to form blood clots have larger plaques in their vessels, but they are more stable.

New strategy found to increase the efficacy of protein-based drugs

A new method for attaching a large protective polymer molecule to a protein appears to improve protein drugs significantly.

National Science Foundation funds CMU for developing revolutionary computational tools

A multidisciplinary team led by Carnegie Mellon University computer scientist Edmund M. Clarke has received a five-year, $10 million grant from the National Science Foundation's Expeditions in Computing program to create revolutionary computational tools that will advance science on a broad array of fronts, from discovering new cancer treatments to designing safer aircraft.

Researchers find connection between eye disease and arginase

Elevated levels of the enzyme arginase contribute to vascular eye damage and Medical College of Georgia researchers say therapies to normalize its levels could halt progression of potentially blinding diseases such as diabetic retinopathy.

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.

ACE inhibitors and AT1R blockers suppress inflammation in mice

Conventional blood pressure medication can treat inflammation in an animal model mimicking multiple sclerosis (MS). This discovery was made by Dr. Michael Platten, head consultant at the department of Neurooncology at Heidelberg University Hospital and head of the Helmholtz Experimental Neuroimmunology Junior Research Group on at the German Cancer Research Center and his team in cooperation with scientists from Stanford University in California.

Cyanide toxicity in smoke inhalation victims

"If commercial flying had as many civilian fatalities as those relating to smoke and fire, there would be a public revolt," said Rob Schnepp, CPTC president and assistant chief of special operations for the Alameda County Fire Department in California. "The numbers aren't going down, and this tells me that we aren't addressing the problem adequately.

Oxygen treatment may speed memory loss associated with Alzheimer's

A 65-year-old women goes into the hospital for routine hip surgery. Six months later, she develops memory loss and is later diagnosed with Alzheimer's Disease. Just a coincidence? Researchers at the University of South Florida and Vanderbilt University don't think so. They suspect that the culprit precipitating Alzheimer's disease in the elderly women may be a routine administration of high concentrations of oxygen for several hours during, or following, surgery - a hypothesis borne out in a recent animal model study.

New insights into identifying children at risk for autoimmune brain disorders

A new study by researchers at Columbia University Mailman School of Public Health's Center for Infection and Immunity indicates that pediatric obsessive-compulsive disorder (OCD), Tourette syndrome and/or tic disorder may develop from an inappropriate immune response to the bacteria causing common throat infections.

Epigenetic alterations may serve as markers for chronic leukemia

A new study shows that certain genes are turned off early, before clinical signs of the disease appear, in the development of chronic leukemia.

New understanding on Gleevec's limitations

University of Michigan researchers have developed an animal model that provides strong evidence why imatinib, marketed as Gleevec, helps patients with chronic myeloid leukemia survive longer, but does not keep the disease from returning if treatment ends.
