- Factor key to severity of community-associated methicillin-resistant staph infections identified
11-11-2007 · EurekAlert!
Newly described proteins in drug-resistant strains of the Staphylococcus aureus bacterium attract and then destroy protective human white blood cells -- a key process ensuring that S. aureus survives and causes severe disease, according to scientists at the National Institute of Allergy and Infectious Diseases, part of the National Institutes of Health.

- More aid required for chronic conditions in low income countries
01-17-2007 · EurekAlert!
Chronic conditions such as cardiovascular disease and cancer result in more deaths and account for more years of healthy life lost than most communicable diseases, and yet little international aid is focused on preventing or treating these conditions. Cardiovascular disease causes 30 percent of all deaths globally and 27 percent of deaths in low income countries. By comparison, HIV/AIDS, tuberculosis and malaria, combined, account for 10 percent of all deaths globally and 11 percent of death in developing countries.

- Natural immune-control system may aid treatment of autoimmune disease and tissue rejection
05-17-2007 · EurekAlert!
The immune system’s ability to police itself may offer a new method of arresting the cells responsible for autoimmune diseases such as multiple sclerosis and for the rejection of transplanted organs and tissues, report scientists at Dana-Farber Cancer Institute.

- Infectious disease researchers develop basis for experimental melanoma treatment
12-07-2006 · EurekAlert!
While investigating a fungus known to cause an infection in people with AIDS, two grantees of the National Institute of Allergy and Infectious Diseases, part of the National Institutes of Health, unexpectedly discovered a potential strategy for treating metastatic melanoma, one of the deadliest forms of skin cancer. The treatment approach, which involves combining an antibody with radiation, has since been further developed and is expected to enter early-stage human clinical studies in 2007.

- Scientists discover novel way to remove iron from ferritin
11-02-2007 · EurekAlert!
A new study led by Children's Hospital Oakland Research Institute senior scientist, Elizabeth Theil, PhD, is the first to suggest that a small protein or heptapeptide could be used to accelerate the removal of iron from ferritin. The results of this study may help scientists develop new medications that dramatically improve the removal of excess iron in patients diagnosed with blood diseases such as B-Thalassemia (Cooley's anemia) or sickle cell disease.

- Genetic marker linked to aggressive prostate cancer
05-20-2007 · EurekAlert!
Northwestern University researchers have discovered that a recently identified genetic marker for prostate cancer is linked to a highly aggressive form of the disease. These findings ultimately will aid the development of a simple blood test to predict who is susceptible to this aggressive cancer. Knowing which patients carry this genetic marker also will guide doctors in how they treat the cancer. The study showed a strong hereditary component to this aggressive cancer.

- Stress contributes to range of chronic diseases, Carnegie Mellon psychologist says
10-09-2007 · EurekAlert!
In a review of the scientific literature on the relationship between stress and disease, Carnegie Mellon University psychologist Sheldon Cohen has found that stress is a contributing factor in human disease, and in particular depression, cardiovascular disease and HIV/AIDS. Cohen’s findings will be published in the Oct. 10 issue of the Journal of the American Medical Association (JAMA). The article was co-authored by Denise Janicki-Deverts of Carnegie Mellon and Gregory E. Miller of the University of British Columbia.

- Laser goes tubing for faster body-fluid tests
04-02-2007 · EurekAlert!
University of Rochester researchers announce in the current issue of Applied Optics a technique that in 60 seconds or less measures multiple chemicals in body fluids, using a laser, white light, and a reflective tube. The technique tests urine and blood serum for common chemicals important to monitoring and treatment of diabetes and cardiovascular, kidney, urinary and other diseases, and lends itself to the development of fast batch testing in hospitals and other clinical settings.

- UCLA study links air pollution to clogged arteries
07-25-2007 · EurekAlert!
Got high cholesterol? Better stay away from air pollution. So says a new study linking diesel exhaust to atherosclerosis, or hardening of the arteries, which significantly increases one’s risk for heart attack and stroke. The research is the first to explain how fine particles in air pollution conspire with artery-clogging fats to switch on the genes that cause blood vessel inflammation and lead to cardiovascular disease.
