Love at first smell

...tocompatibility Complex (MHC) molecules identify a disease as a foreign invader. Different MHC molecules fight different diseases, so it's important to have a mix of MHC types. Females use smell to identify partners with suitable MHC molecules: choosing only males with the correct mix of immune genes critica...

Affymetrix and the Karolinska Institutet Announce Translational Medicine Strategic Alliance

...ing existing diseases, to being able to predicting disease susceptibility and an individual's response to drugs," said Patrick Kelly, European Site Manager and Vice President, Affymetrix. "This is what personalized medicine is all about -- enabling clinicians to detect diseases earlier and manage them more e...

New Treatment Rivals Chemotherapy For Lymphoma, Study Finds

...tients initially have a response to treatment, the disease almost always comes back and becomes more difficult to treat. Bexxar, whose chemical name is tositumomab and iodine I 131 tositumomab, combines an antibody that seeks out cancer cells, and a radioactive form of the element iodine. When injected, it ...

Implanted Devices Detect High-Risk Heart Failure Patients

...lt for cardiologists to get a true idea of how the disease is progressing," said Gilliam, chief of electrophsysiology at Duke. "This study shows that changes in heart rate variability just might be better in picking out those people at highest risk." In their analysis of 1,411 heart failure patients who rec...

How an AIDS-Related Cancer Unleashes Inflammation

...one way that Kaposi's sarcoma ?a cancer-like viral disease traditionally associated with AIDS ?triggers severe inflammation. Don Ganem, a Howard Hughes Medical Institute (HHMI) investigator, and HHMI associate Craig McCormick, who are both at the University of California, San Francisco, published their find...

Wiley announces publication of Databasing the Brain

...nction, and development of the brain in health and disease represents one of the great scientific challenges of our time. The emerging field of neuroinformatics integrates neuroscience with informatics to create unique databases and analytical tools for the large variety of neuroscience data types, applying ...

Chemists identify key gene in development of type 1 diabetes

Vascular structure and function improve with diet and exercise

...ructural and functional measures of cardiovascular disease risk may improve by the eighth week of a diet and exercise regimen, according to a study presented today at the American Heart Association's Sixth Annual Conference on Arteriosclerosis, Thrombosis and Vascular Biology. "Our lifestyle management prog...

New Insights Into HIV Immunity Suggest Alternative Approach to Vaccines

Researchers develop rapid diagnostic tool for pathogen identification

...form addresses important challenges for infectious disease identification—sensitivity and breadth. Mass Tag PCR provides the ability to be precise in identification, as well as the ability to apply current diagnostics to more than one pathogen at a time, thereby reducing the time needed for differential diag...

Protein offers way to stop microscopic parasites in their tracks

...s, is one of the most common causes of water-borne disease in the world. "These other parasites are more devastating in terms of the number of people they affect, but they're somewhat harder to work on," Sibley explains. "Because it's so much easier to study, we use Toxoplasma as a way to ask about very bas...

Rats infected as newborns grew up vulnerable to memory problems during an immune challenge

...r to explain some of the individual variability in disease susceptibility, other than genetic variation, in animals in the wild and perhaps humans." The authors conclude that neonatal infection can create later problems by changing how well the body can respond to future immune challenges. Those changes aff...

A new study examines how shared pathogens affect host populations

...ural importance. Many pathogens like malaria, Lyme disease or West Nile encephalitis that infect multiple hosts are commonly transmitted by vectors, and their transmission rate is often thought to depend on the proportion of hosts or vectors infected (i.e. frequency dependence). A study, to appear in the Jul...

Potential treatments for neurofibromatosis
