Link between common cold and ear infection
A new five-year study at the University of Texas Medical Branch at Galveston confirms the suspected close link between the two most common diseases of young children: colds and ear infections. The study, which appears in the March 15 issue of Clinical Infectious Disease, confirmed the suspected close link between the two most common diseases of young children, viral colds and ear infections. It also identified the viruses linked to higher rates of ear infections……..

No commentsPreventing spread of ovarian cancer
A drug that blocks production of an enzyme that enables ovary cancer to gain a foothold in a new site can slow the spread of the disease and prolong survival in mice, as per a research studyby scientists from the University of Chicago Medical Center, but only if the drug is given early in the disease process……..

No commentsMemory on Trial
The U.S. legal system has long assumed that all testimony is not equally credible, that some witnesses are more reliable than others. In tough cases with child witnesses, it assumes adult witnesses to be more reliable. But what if the legal system had it wrong? Scientists Valerie Reyna, human development professor, and Chuck Brainerd, human development and law school professor–both from Cornell University–argue that like the two-headed Roman god Janus, memory is of two minds–that is, memories are captured and recorded separately and differently in two distinct parts of the mind……..

No commentsHow diabetes drives atherosclerosis
Scientists have discovered how diabetes, by driving inflammation and slowing blood flow, dramatically accelerates atherosclerosis, as per research would be reported in the March 14 edition of the journal Circulation Research. Experts once believed that atherosclerosis, or hardening of the arteries, developed when too much cholesterol clogged arteries with fatty deposits called plaques. When blood vessels became completely blocked, heart attacks and strokes occurred. Today most agree that the reaction of the body’s immune system to fatty build-up, more than the build-up itself, creates heart attack risk. Immune cells traveling with the blood mistake fatty deposits for intruders, akin to bacteria, home in on them, and attack. This causes inflammation that makes plaques more likely to swell, rupture and cut off blood flow……..

No commentsPain Receptor in Brain and Memory
Researchers have long known that the nervous system receptor known as TRPV1 can affect sensations of pain in the body. Now a group of Brown University researchers has observed that these receptors - a darling of drug developers - also may play a role in learning and memory in the brain. In surprising new research, reported in the journal Neuron, Julie Kauer and her team show that activation of TPRV1 receptors can trigger long-term depression, a phenomenon that creates lasting changes in the connections between neurons. These changes in the brain - and the related process of neural reorganization known as long-term potentiation - are thought to bethe cellular basis for memory making……..

No commentsHow to block Fugitive cancer cells
Cancer cells get a helping hand from platelets, specialized blood cells involved in clotting. Platelets shelter and feed tumor cells that stray into the bloodstream, making it easier for cancer to spread, or metastasize. Research at Washington University School of Medicine in St. Louis suggests that inactivating platelets could slow down or prevent metastasis……..

No commentsParadoxical Alzheimer’s finding linking memory loss
Do you remember the seventh song that played on your radio on the way to work yesterday? Most of us dont, thanks to a normal forgetting process that is constantly cleaning house culling inconsequential information from our brains. Scientists at the Buck Institute now think that this normal memory loss is hyper-activated in Alzheimers disease (AD) and that this effect is key to the profound memory loss linked to the incurable neurodegenerative disorder……..
