Mysterious 'neural noise' actually primes brain for peak performance
Researchers at the University of Rochester may have answered one of neuroscience's most vexing questions--how can it be that our neurons, which are responsible for our crystal-clear thoughts, seem to fire in utterly random ways? In the November issue of Nature Neuroscience, the Rochester study shows that the brain's cortex uses seemingly chaotic, or "noisy," signals to represent the ambigu...Asthma may actually be prevented by Dust and Dirt
National Jewish Medical and Research Center researchers in USA say that a little dust and dirt in the home may help prevent asthma later in life. Environmental endotoxin may have an allergy-protective effect in some infants whose homes have high levels of the bacteria by-product. "Endotoxin seems to drive the immune system to produce cytokines that inhibit certain processes in the body th...Stroke Risk and Fish :A factual interconnection
Eating fish at least once a month can minimise the risk of ischemic stroke in men according to the Harvard researchers. Around 607 participants developed stroke over a period of 13 years in the new study involving more than 43,005 men aged 39 to 76. Ischemic stroke// which is caused by a clot that blocks the blood vessel supplying the brain with blood was confirmed with 378 partic...Head injury X-rays may actually be causing harm
A BANG on the head may do less harm than the X-rays used to diagnose the degree of damage, a study suggests. In research that is likely to have a significant effect on// how children with minor head injuries are treated, Swedish scientists have shown that even low doses of radiation can impair intellectual development. The doses involved are typical of those used in CT scans, which...Cancer Patients Might Be Able To Actually Help Themselves
New research looks at why and what can be done to activate the cells to destroy tumors. Researchers say the failure of these immune cells to kill // cancer may be due to different cell priming or suppressing mechanisms. Researchers now say that they have found a method to activate the anti-cancer cells in mice. For the study, researchers took bone marrow from breast cancer patients and...Calcium Supplementation May Not Actually Prevent colon cancer say researchers
Researchers now say that calcium previously thought to inhibit the growth of colon cancer cells// may not actually be true due to inconsistent results obtained in a number of studies. However researchers say that results of two well-designed, randomized controlled trials, have shown a moderate protective effect on development of colorectal adenomatous polyps, generally benign types occu...Skin Rash Actually Signifies Better Outcomes for Pancreatic and Lung Cancer Patients
PHILADELPHIA, July 3, 2007-- – The appearance of arash in cancer patients treated with erlotinib (Tarceva) isstrongly associated with longer survival, according to researchersfrom the drug’s developer, OSI Pharmaceuticals, Inc. This isnot the first time that rash has been associated with a survivaladvantage with EGFR inhibitors – a class of drugs whichincludes erlotinib...
