Does the body’s synthesis of certain substances affect the relationship between obesity and blood pressure?

The number of overweight Americans has reached record levels, and obesity now affects almost one in three citizens. Published findings from the 1999-2000 report of the National Health and Nutrition Examination Survey (NHANES), the definitive measure for weight matters in the United States, show that 59 million (31 percent) of adults are obese. One third of adult women are obese

Researchers at Stanford University Medical Center have identified a genetic marker that can explain why some people experience side effects to common antidepressants while others do not. They also found that a key liver enzyme involved in breaking down these antidepressants surprisingly played no role in the development of side effects nor in how well the drugs worked. The findings may lead to fewer side effects for patients undergoing antidepressant drug therapy.

“Antidepressants are among

A new technique accurately identifies breast cancers that are difficult to detect with conventional mammography, according to a study appearing in the October issue of the journal Radiology.

“The dual-energy contrast-enhanced digital subtraction mammography technique is feasible for hard-to-demonstrate breast cancers and is worthy of further study,” said the study’s lead author, John M. Lewin, M.D. Dr. Lewin is an associate professor of radiology at the University of Colorado Health Sc

Girls who go through puberty earlier than their peers are more likely to be involved in delinquency, but not for the reasons often suspected, according to a new study.

Researchers had long speculated that early-developing girls were nudged into delinquency because they had more older friends, and more male friends.

But, instead, new research suggests that the key factors appear to be the fact that these girls are dating and that they have more friends – regardless of age – w

If Mohini Sain has his way, cars of the future may be fitted with tough, durable and completely biodegradable bumpers made of hemp.

Sain, a professor in the University of Toronto’s Faculty of Forestry and Department of Chemical Engineering and Applied Chemistry, creates biocomposites from processed plant fibres. His latest research, published in the August issue of Materials Research Innovations and the July issue of Macromolecular Materials and Engineering, describes a way to create a

With new, one-of-a-kind test equipment, National Institute of Standards and Technology (NIST) researchers aim to stamp out costly, delay-causing errors in the design of dies used to make sheet-metal parts ranging from car hoods to airplane wings to pots, pans and cans.

The U.S. auto industry alone is estimated to spend more than $700 million a year on designing, testing, and correcting new dies for its latest models, each containing about 300 stamped parts shaped by dies and presses. About
