Virus discovery helps scientists predict emerging diseases‎

Fresh insight into how viruses such as SARS and flu can jump from one species to another may help scientists predict the emergence of diseases in future.
"Emerging diseases such as SARS, HIV and some types of flu have all got into humans from other species. Understanding how diseases jump between different species is essential if we want to predict the appearance of new diseases in the future."
- Dr Ben Longdon of the University of Edinburgh's School of Biological Sciences

Built-in Molecular Brakes Curb The Sniffles

Johns Hopkins Medical Institutions, Wed January 17, 2007, [PRESS RELEASE]
Baltimore, MD - Researchers at Johns Hopkins have discovered how our anti-infection machinery turns itself down and limits the sniffles, congestion and fevers that are a side effect of the campaign against invading viruses. The discovery seems to solve part of the mystery of why the misery of the common cold lasts only so long.

Antivirals effectively curb influenza virus

Fred Hutchinson Cancer Research Center, Tue January 16, 2007, [PRESS RELEASE]
Seattle - Two antiviral drugs, oseltamivir and zanamivir, are highly effective when given as a preventive measure to reduce the spread of the influenza virus, according to an analysis of household-based studies by researchers at Fred Hutchinson Cancer Research Center, University of Michigan and University of Virginia, published in the current print edition of the American Journal of Epidemiology.

Einstein’s tea leaves inspire new blood separation technique

American Institute of Physics, Tue January 16, 2007, [PRESS RELEASE]
Scientists at Monash University in Australia have developed a process for rapidly and efficiently separating blood plasma at the microscopic level without any moving parts, potentially allowing doctors to do blood tests without sending samples to a laboratory.

‘Beavertail’ surgery helps tongue cancer patients

University of Alberta, Tue January 16, 2007, [PRESS RELEASE]
Edmonton, Alberta - A new surgical technique pioneered at the University of Alberta has given back the ability to swallow to patients with tongue cancer.

New gene targeted for Alzheimer disease

Case School of Medicine, Mon January 15, 2007, [PRESS RELEASE]
Cleveland, OH - Robert Friedland, M.D., Professor in the Department of Neurology, and a team of investigators at Case School of Medicine, in collaboration with an international effort by researchers led by Boston University School of Medicine (BUSM), the University of Toronto and Columbia University Medical Center, have uncovered a major new gene SORL1 ֖ for late-onset Alzheimer disease. Replicated in four distinct ethnic groups, SORL1 is only the second gene discovered for late-onset Alzheimers. APOE, the first gene, was identified in 1993.

Alzheimer’s gene identified:  study

University of Toronto, Sun January 14, 2007, [PRESS RELEASE]
Toronto - An international effort led by scientists at the University of Toronto, Columbia University and Boston University has isolated another gene responsible for Alzheimer's disease.

Profiling of cancer genes may lead to better and earlier detection

UT Southwestern Medical Center, Mon December 25, 2006, [PRESS RELEASE]
Dallas - A research team at UT Southwestern Medical Center has for the first time identified several genes whose expression is lost in four of the most common solid human cancers -- lung, breast, prostate and colon cancer.

Findings Could Lead To A Safer And More Effective Method To Control Mosquito-caused Malaria

Mayo Clinic, Mon December 25, 2006, [PRESS RELEASE]
A Mayo Clinic researcher has discovered a target site within malaria-carrying mosquitoes that could be used to develop pesticides that are toxic to the Anopheles gambiae mosquito and other mosquito species.

New study gives further hope that vitamin D can fight breast cancer

Imperial College London , Mon October 16, 2006, [PRESS RELEASE]
London - Vitamin D may help curb breast cancer progression, according to a study published today in the Journal of Clinical Pathology. The authors, from Imperial College London, measured the levels of vitamin D in the blood serum of 279 women with invasive breast cancer. The disease was in its early stages in 204 of the women, and advanced in the remaining 75.

Human Stem Cells Delay Start Of Lou Gehrig’s Disease In Rats

Johns Hopkins Medical Institutions, Sun October 15, 2006, [PRESS RELEASE]
Researchers at Johns Hopkins have shown that transplanting human stem cells into spinal cords of rats bred to duplicate Lou Gehrig's disease delays the start of nerve cell damage typical of the disease and slightly prolongs life.

3-D Brain Atlas To Help Unlock Mysteries Of Neurological Disorders

Science Daily, Sun October 01, 2006, [PRESS RELEASE]
The Allen Institute for Brain Science has announced the completion of the groundbreaking Allen Brain Atlas, a Web-based, three-dimensional map of gene expression in the mouse brain. Detailing more than 21,000
genes at the cellular level, the Atlas provides scientists with a level of data previously not available.

Scientists stop colon cancer growth in mice by blocking just one enzyme

EurekAlert, Sat September 30, 2006, [PRESS RELEASE]
In cell culture experiments, scientists from the University of Texas Medical Branch at Galveston and the University of Texas at Arlington determined that stopping the activity of a single enzyme called aldose reductase could shut down the toxic network of biochemical signals that promotes inflammation and colon cancer cell growth.

Using contrast enhanced sonography improves diagnosis of liver and spleen injuries

EurekAlert, Fri September 29, 2006, [PRESS RELEASE]
Contrast-enhanced sonography shows liver and spleen injuries better than non-contrast enhanced sonography, according to a study conducted at the University of California, Davis School of Medicine department of radiology in Sacramento, Calif.

Bacterial Protein Shows Promise In Treating Intestinal Parasites

Science Daily, Fri September 29, 2006, [PRESS RELEASE]
Scientists at the University of California, San Diego and Yale University have discovered that a natural protein produced by Bacillus thuringiensis, a bacterium sprayed on crops by organic farmers to reduce insect damage, is highly effective at treating hookworm infections in laboratory animals.
