Saying goodbye to summer can be difficult for everybody. In some people the onset of winter triggers Seasonal Affective Disorder, or SAD, a mood disorder in which sufferers experience symptoms of depression. Happily, a special kind of gerbil exhibits remarkably similar reactions to SAD treatments as humans, opening a promising new channel for study and treatment of the common complaint.
CHICAGO --- Northwestern Medicine researchers at the Robert H. Lurie Comprehensive Cancer Center of Northwestern University have found that a new, nontoxic drug made from a chemical in soy could prevent the movement of cancer cells from the prostate to the rest of the body.
These findings will be presented at the Ninth Annual American Association for Cancer Research Frontiers in Cancer Prevention Research Conference.
University of Toronto scientists have found that chemicals used to line junk food wrappers and microwave popcorn bags are migrating into food and being ingested by people where they are contributing to chemical contamination observed in blood.
Perfluorinated carboxylic acids or PFCAs are the breakdown products of chemicals used to make non-stick and water- and stain-repellant products ranging from kitchen pans to clothing to food packaging. PFCAs, the best known of which is perfluorooctanoic acid (PFOA), are found in humans all around the world.
A new study shows how an amphibious fish stays alive for up to two months on land. It's all in the skin.
The messenger interleukin-27 plays an important role when the human body blocks inflammations. This was discovered by an international research team, of which the Kiel Professors Joachim Grötzinger and Stefan Rose-John, as well as the doctoral candidate, Björn Spudy, are a part of. The research findings of the scientists from Kiel, the US and Great Britain were published yesterday, Sunday (7 November 2010), in the online advance edition of Nature Immunology.
A new study by researchers at the Johns Hopkins Bloomberg School of Public Health examines the burden of HIV and sexually transmitted disease among male clients of the commercial sex industry in China's Sichuan province. Since 2007, heterosexual transmission has replaced injecting drug use as the primary transmission mode of all HIV infections in China. The study is available online in advance of publication in the journal Sexually Transmitted Infections.
BOSTON – Using a novel, real-time imaging system, scientists have tracked a group of near-infrared fluorescent nanoparticles from the airspaces of the lungs, into the body and out again, providing a description of the characteristics and behavior of these minute particles which could be used in developing therapeutic agents to treat pulmonary disease, as well as offering a greater understanding of the health effects of air pollution.
Breast cancer patients are more likely to have joint pain from taking aromatase inhibitors (AIs) if they have advanced stage cancer, according to a study presented at the American College of Rheumatology's annual meeting, held Nov. 7-11, in Atlanta. The study is one of the first to identify factors that increase the likelihood that a patient will suffer joint pain from AI therapy.
"The results of this study show that fearless behavior in children can be identified and is related to neurological and genetic predisposition. This type of behavior has less correlation – at least in infancy – with standards of educational processes or parenting practice," says Dr. Inbal Kivenson-Baron, who carried out the study.
Scientists have found that the fat cells and tissues of morbidly obese people and animals can reach a limit in their ability to store fat appropriately. Beyond this limit several biological processes conspire to prevent further expansion of fat tissue and in the process may trigger other health problems.
Privacy legislation and protocols to safeguard the health information of members of the military are lacking, and the head of Canada's military must take action to ensure health privacy for all staff, states an editorial in the Canadian Medical Association Journal (CAMJ) http://www.cmaj.ca/cgi/doi/10.1503/cmaj.101630.
Recent violations at Veterans Affairs Canada of privacy regarding sensitive health information raise questions about the military's ability to protect personal health information.
New evidence has emerged that the use of mild painkillers such as paracetamol, aspirin and ibuprofen, may be part of the reason for the increase in male reproductive disorders in recent decades.
Scientists have made a significant discovery about how the body defends itself against snail fever, a parasitic worm infection common in developing countries.
Researchers studied the immune response in mice infected with snail fever parasites. They found that a particular type of immune cell, known as the dendritic cell, is responsible for triggering the immune system's defence against the invading parasite.
