A survey of health care workers has revealed that as many as 85% may stay off work if an influenza pandemic did take hold of the country. The results of the survey, published in the open access journal BMC Public Health, suggest that levels of absenteeism may be significantly higher than current official estimates and that 'willingness', rather than 'ability', plays the largest role in health care workers' decisions as to whether to go to work or not.

TUCSON, Ariz. --Youngsters suffering severe nerve poisoning following a scorpion sting recover completely and quickly if a scorpion-specific antivenom is administered, according to a study conducted by researchers from The University of Arizona and reported in the May 14 issue of The New England Journal of Medicine.

A new study by researchers at Woods Hole Oceanographic Institution (WHOI) and the University of California, Santa Barbara (UCSB) is the first to quantify the amount of oil residue in seafloor sediments that result from natural petroleum seeps off Santa Barbara, California.

The new study shows the oil content of sediments is highest closest to the seeps and tails off with distance, creating an oil fallout shadow. It estimates the amount of oil in the sediments down current from the seeps to be the equivalent of approximately 8-80 Exxon Valdez oil spills.

Twenty years ago, the oil tanker Exxon Valdez was exiting Alaska's Prince William Sound when it struck a reef in the middle of the night.

What happened next is considered one of the nation's worst environmental disasters: 10.8 million gallons of crude oil spilled into the pristine Alaskan waters, eventually covering 11,000 square miles of ocean.

Now, imagine 8 to 80 times the amount of oil spilled in the Exxon Valdez accident.

HOUSTON – (May 13, 2009) – The beta-carotene in so-called "Golden Rice" converts to vitamin A in humans, according to researchers at Baylor College of Medicine (www.bcm.edu) and Tufts University in an article that appears in the current issue of the American Journal of Clinical Nutrition.

Researchers at the Georgia Institute of Technology have built a test facility to evaluate and enhance sensors designed to detect buried land mines. The unique automated system measures the response of individual electromagnetic induction sensors or arrays of sensors against land mines buried at many possible angles.

The method of building a rabbit rectal VX2 carcinoma model by injecting the cell suspension of VX2 cells into the wall of the rectum guided by X-ray fluoroscopy is feasible. The advantages of the model are ease of establishment, short growth period, and high stability. The rectal VX2 carcinoma established in this rabbit model is similar to human rectal carcinoma in aspects of pathological representation, tumor development, and metastasis.

COLUMBIA, Mo. – Aging adults living in nursing homes and relying on the care of others are often susceptible to a long list of medical problems. These problems are debilitating for the residents and cost facilities millions of dollars. In a new study, a University of Missouri researcher found that long-term care facilities in Missouri saved more than $6 million in the past three years after implementing a quality care improvement program. Savings for the facilities were more than 10 times the program costs.

A meta-analysis of 17 randomised controlled trials has shown that pre-procedural treatment with sodium bicarbonate based hydration is the optimal treatment strategy to prevent contrast-induced nephropathy (CIN). The research, published in the open access journal BMC Medicine, shows that although the benefit may have been overestimated by previous studies, sodium bicarbonate is clearly superior to normal saline.
