New research from Mount Sinai School of Medicine has discovered that rhodopsin, a pigment of the retina that is responsible for the first events in the perception of light, may also be involved in temperature sensation. This detection had not been revealed in previous studies.

The DNA studies carried out by a team of Spanish and Greek researchers, and published in the Journal of Agricultural and Food Chemistry, show that more than 30% of the hake products sold in Spain and Greece are wrongly labelled.
"We have found that hake caught in Africa are being labelled as American or European, meaning consumers pay a higher price for them", Eva García Vázquez, a professor at the University of Oviedo (Spain) and co-author of the study, tells SINC.
The relative rate of alcohol-related chronic pancreatitis (CP) is lower when compared to other causes, according to a new study in Clinical Gastroenterology and Hepatology, the official journal of the American Gastroenterological Association (AGA) Institute. Patients with no identifiable cause for their disease as well as those with non-alcohol-related causes represent an unexpectedly large subgroup, particularly among women.
Seventy per cent of men who received androgen-deprivation therapy (ADT) after surgery to remove their prostate gland gained significant weight in the first year, putting on an average of 4.2kg, according to a paper in the March issue of the urology journal BJUI.
Researchers studied the recorded weights of 132 men who underwent radical prostatectomy between 1988 and 2009 at four US Veterans Affairs Medical Centers in California, Georgia and North Carolina, before and after they received ADT.
Human Immunodeficiency Virus (HIV) – which causes AIDS – invades human immune cells and causes them to produce new copies of the virus, which can then infect new cells. A research team led by Professor Don C. Lamb (Ludwig-Maximilians-Universität in Munich) and Priv.-Doz. Dr. Barbara Müller of Heidelberg University Hospital have now analyzed the involvement of particular components of the infected cell in virion release, and discovered that the enzyme VPS4A plays a more active role in the process than was previously thought. VPS4A was already known to act after virus budding was complete.
LA JOLLA, CA – March 10, 2011 – Scientists at The Scripps Research Institute and University of Pennsylvania have found a way to uncover potential drug targets that have so far remained hidden from researchers' view.
By applying the new method to a type of nerve cell critical to regulating body temperature, the authors found more than 400 "receptors" (structures that bind other molecules, triggering some effect on the cell) responding to neurotransmitters, hormones, and other chemical signals. This represents 20 to 30 times more receptors than previous studies had identified.
[EMBARGOED FOR MARCH 11, 2011] Low bone mineral density in HIV-infected patients is common and raises concerns about increased risks of fracture. Although there have been several studies regarding bone mineral density, there have been few data on rates of fracture in this population.
NEW YORK (March 11, 2011) -- During a regular annual physical exam, blood is usually drawn to check the health of a person's heart, kidneys and liver. Now, researchers at NewYork-Presbyterian Hospital/Weill Cornell Medical Center say a blood test that detects the early development of emphysema -- well before symptoms occur -- may someday also be offered.
NAFLD is a condition where fat accumulates in the liver (steatosis) and can lead to liver inflammation (nonalcoholic steatohepatitis or NASH) and permanent liver damage (fibrosis/cirrhosis). NAFLD affects anywhere from 11% to 45% of some populations and is associated with obesity, hypertension, and problems regulating serum lipids or glucose.
Postmenopausal women have a new health message to hear. Two annual dental checkups aren't enough. Older women need more, according to research findings from the Case Western Reserve University School of Dental Medicine and the Cleveland Clinic.
That message comes from a comparison study of women on and off bone-strengthening bisphosphonate therapies for osteoporosis.
LA JOLLA, CA – March 10, 2011 – Scientists from The Scripps Research Institute have determined a new structure from a medically important superfamily of proteins. The structure should help instruct the design of a new kind of therapeutics for conditions ranging from Parkinson's disease to inflammation.
A University of Alberta researcher says grocery retailers need to take heed that a jump at the pumps will be a blow to their bottom line. Alberta School of Business professor Yu Ma notes that if stores want to survive, they'll have to change their tactics in the face of rising gas prices in order to attract shoppers "hungry" for better deals.
New Orleans, LA – LSU oncologist Vince D. Cataldo, MD, is the lead author of a review article reporting two chemotherapy drugs now indicated for second and third-line therapy in patients with advanced non-small-cell lung cancer are remarkably effective in treating a certain subset of these patients. Dr. Cataldo, a Clinical Assistant Professor of Medicine at LSU Health Sciences Center New Orleans School of Medicine, practicing at LSU's Earl K.
Earth's biodiversity—the number of microorganisms, plants, and animals, their genes, and their ecosystems (such as rainforests and grasslands)—is declining at an alarming rate, even faster than the last mass extinction 65 million years ago. In fact, two thirds of the terrestrial species that exist today are estimated to be extinct by the end of this century. Humans are an integral part of this extensive network of life.
