Study Links Enzyme to Insulin Resistance

Tue Mar 19, 2002

NEW YORK (Reuters Health) - High blood levels of a naturally occurring compound involved in blood vessel function may be the "missing link" between insulin resistance, a precursor to type 2 diabetes, and heart disease.

The study findings also suggest drugs that improve insulin sensitivity may reduce levels of the compound, ADMA, and ultimately lower a person's heart disease risk.

Short-sightedness may be tied to refined diet

by Douglas Fox

The food children eat might play as big a role as books and computer screens when it comes to causing short-sightedness.

Diets high in refined starches such as breads and cereals increase insulin levels. This affects the development of the eyeball, making it abnormally long and causing short-sightedness, suggests a team led by Loren Cordain, an evolutionary biologist at Colorado State University in Fort Collins, and Jennie Brand Miller, a nutrition scientist at the University of Sydney.

Painless needle copies mosquito's stinger

April 3, 2002

by David Cohen

A needle which mimics the mosquito's unique "stinger", making injections painless, has been developed by a team of Japanese microengineers.
Contrary to popular belief, a mosquito can stab you with its proboscis without you feeling a thing. It then injects anticoagulant saliva to stop your blood clotting while it feeds, and it is this that carries the bacteria that cause irritation and pain.

Nicotine Lollipops Cause Concern in US

Wed Apr 3, 2002

By Lisa Richwine

WASHINGTON (Reuters) - Sucking on nicotine-laced lollipops is catching on as a way to quit smoking, but critics Wednesday worried about the products' appeal to children and urged a ban until studies prove they are safe and effective.

Sold in flavors such as apricot, eggnog and watermelon, the lollipops are available at some pharmacies and over the Internet. Unlike gums and patches to kick the tobacco habit, the lollipops do not have Food and Drug Administration approval.

Infant Screening for Cancer Found Ineffective

NEW YORK (Reuters Health) - Screening infants for a type of childhood cancer does not appear to cut death rates and could actually cause harm by leading to unnecessary treatment, according to the results of two studies released Wednesday.

Muscle, Bone Mass Linked in Rheumatoid Arthritis

Wed Apr 3, 2002

By David Douglas

NEW YORK (Reuters Health) - Women with rheumatoid arthritis are at high risk of developing the bone-thinning disease osteoporosis, but exercise could help strengthen the bones of these patients, Danish researchers report.

In rheumatoid arthritis, the body's immune system attacks joint tissues, leading to damage in many parts of the body, including bone, cartilage and various internal organs. The disease can cause severe disabilities, particularly in older people, and its exact causes are still not known.
