The U.S. Food and Drug Administration today proposed a new regulation that sets standards for formulating, testing and labeling over-the-counter (OTC) sunscreen drug products with ultraviolet A (UVA) and ultraviolet B (UVB) protection.
With new diseases emerging at an unprecedented rate in an increasingly interconnected world, often with the ability to cross borders rapidly, global public health security depends on international cooperation and surveillance more than at any previous time in history, the United Nations health agency warned in its annual report today.
People with chronic, intractable back pain know exactly what they need ? relief directly where it hurts. Peripheral nerve field stimulation (PNFS), the newest weapon against back pain for people who are finding no relief from conventional treatment, does just that, says Dr. Eugene Lipov, who is Director of Research, Alexian Brothers Hospital Network Pain Program.
Scientists have shown in literally thousands of studies that the p53 gene deserves its reputation as ?the guardian of the genome.? It calls to action an army of other genes in the setting of varied cell stresses, permitting repair of damaged DNA or promoting cell death when the cell damage is too great. A key net effect of p53?s action is to prevent development of cancerous cells.
Plastic pipes, which are increasingly being used in place of copper water pipes, can significantly affect the odor and taste of drinking water, according to a pioneering study on the subject. The study will be presented in August at the American Chemical Society national meeting in Boston.
A collaborative team of scientists from the Uniformed Services University of the Health Sciences (USU) here, and the Australian Animal Health Laboratory have demonstrated an important biological feature of the deadly Nipah virus that can infect and kill both animals and humans.
Twenty-two years of dedicated research has finally resulted in success: In the journal Angewandte Chemie, a British team headed by Steven V. Ley at the University of Cambridge reports the first synthesis of azadirachtin, a natural compound that stops predatory insects from feeding.
Researchers at the University of Pittsburgh School of Medicine?s department of emergency medicine, in collaboration with the Allegheny County Fire Academy, have received a Federal Emergency Management Agency (FEMA) Fire Prevention and Safety grant to conduct a study designed to develop optimal methods of reducing acute cardiovascular risk resulting from exposure to heat stress during fire suppression.
The first comprehensive national survey of sexual attitudes, behaviors and problems among older adults in the United States has found that most people ages 57 to 85 think of sexuality as an important part of life and that the frequency of sexual activity, for those who are active, declines only slightly from the 50s to the early 70s.
Using genetic engineering, researchers have created an obsessive-compulsive disorder (OCD) – like set of behaviors in mice and reversed them with antidepressants and genetic targeting of a key brain circuit.
