Studies expand understanding of X chromosome
The National Institutes of Health (NIH) hailed the first comprehensive analysis of the sequence of the human X chromosome, saying that this provides sweeping new insights into the evolution of sex chromosomes and the biological differences between males and females. These studies, a detailed analysis of the X chromosome’s DNA sequence and a survey of its gene activity, are published in the current issue of the journal Nature.  more

Obesity threatens to cut U.S. life expectancy, new analysis suggests
Over the next few decades, life expectancy for the average American could decline by as much as 5 years unless aggressive efforts are made to slow rising rates of obesity, according to a team of scientists supported in part by the National Institute on Aging (NIA), a component of the National Institutes of Health (NIH) of the Department of Health and Human Services (DHHS).  more

Invasive pneumonia and antibiotic resistance decreased after childhood vaccine introduced
The problem of increasing antibiotic resistance in cases of Streptococcus pneumoniae, a major cause of pneumonia, meningitis and sepsis, was dramatically reversed following the licensing and use of a new conjugate vaccine for young children in February 2000, according to research conducted at Emory University, the Atlanta Veterans Affairs Medical Center, the Centers for Disease Control and Prevention, and the Georgia Division of Public Health. The researchers also found a significant decrease in the incidence of invasive pneumococcal disease in both vaccinated children and unvaccinated adults after the vaccine was introduced.  more

Institute for Medical Research scientists identify gene critical to type 1 diabetes
An international team of scientists, led by Yousef Al-Abed, PhD, a medicinal chemist at the Institute for Medical Research of the North Shore-Long Island Jewish (LIJ) Health System in Manhasset, NY, has identified a gene that plays a critical role in the development of type 1 diabetes. This is the type of diabetes that typically arises in childhood, requires insulin injections for life and can have serious complications like heart disease, kidney disease and blindness. The identification of this gene opens the door to new drugs and gene therapy. Dr. Al-Abed described the team's findings today at the 229th national meeting of the American Chemical Society in San Diego, CA. more
