During periods of fasting, brain cells responsible for stimulating the appetite make sure that you stay hungry. Now, a new study of mice reported in the January issue of the journal Cell Metabolism, published by Cell Press, reveals the complex series of molecular events that keep those neurons active.
In a three-year study, 728 older men and women with high blood homocysteine levels and no hearing loss were given either daily oral folic acid or a placebo supplement. Daily folic acid supplementation slowed decline in hearing of low frequencies by 0.7dB after three years.
In an advance in the emerging field of bacterial imaging, scientists are reporting development of a method for identifying specific sites of localized bacterial infections in living animals. Bradley D. Smith at the University of Notre Dame and colleagues describe the method in a report scheduled for the Jan. 10 edition of the Journal of the American Chemical Society, a weekly publication.
Within hours of the first reports of devastating floods this week in the Indonesian province of Aceh, WFP moved rapidly to deliver emergency supplies by air and road to some 127,000 displaced people in the hardest hit districts of Aceh Tamiang and Gayo Lues.
The draft guidance for industry addresses the use of food and feed products derived from clones and their offspring. The guidance is directed at clone producers, livestock breeders, and farmers and ranchers purchasing clones. It provides the agency’s current thinking on use of clones and their offspring in human food or animal feed.
The proposed risk management plan by FDA addresses risks to animal health and potential remaining uncertainties associated with feed and food from animal clones and their offspring.
Auckland health authorities are on high alert for a possible outbreak of infectious hepatitis A after a sick McDonald’s worker handled food at one of Auckland’s busiest restaurants. The worker may have exposed hundreds of customers to the virus during an evening shift at the Greenlane restaurant just over a fortnight ago.
Adults living with children eat more saturated fat — the equivalent of nearly an entire frozen pepperoni pizza each week — than do adults who do not live with children, according to a University of Iowa and University of Michigan Health System study.
The FDA’s draft risk assessment finds that meat and milk from clones of adult cattle, pigs and goats, and their offspring, are as safe to eat as food from conventionally bred animals. The assessment was peer-reviewed by a group of independent scientific experts in cloning and animal health. They agreed with the methods FDA used to evaluate the data and the conclusions set out in the document.
Researchers at Purdue University have used a new technique to rapidly detect and precisely identify bacteria, including dangerous E. coli, without time-consuming treatments usually required.
