Between 700,000 and one million children under the age of five die each year from pneumococcal disease, equivalent to malaria and more than AIDS and tuberculosis (2,3)........ ]]> http://medicineworld.org/cancer/lead/10-2008/molecule-schizophrenia-relapse.html http://medicineworld.org/cancer/lead/10-2008/molecule-schizophrenia-relapse.html Wed, 15 Oct 2008 23:54:49 GMT A factor that helps optimize brain formation and function may also provide clues about whether patients suffering with schizophrenia are headed toward relapse, scientists say. Over the next two- and one-half years, they are regularly measuring levels of brain-derived neurotrophic factor, or BDNF, in the blood of patients with schizophrenia to see if the pattern of their rise and fall is a good indicator that patients are headed for trouble, say Medical College of Georgia researchers........ ]]> http://medicineworld.org/cancer/lead/10-2008/predicts-whether-liver-cancer-likely-to-recur.html http://medicineworld.org/cancer/lead/10-2008/predicts-whether-liver-cancer-likely-to-recur.html Wed, 15 Oct 2008 23:54:49 GMT Scientists are poised to unlock the genetic secrets stored in hundreds of thousands of cancer biopsy samples locked in long-term storage and previously believed to be useless for modern genetic research. With the aid of a new technique developed by Howard Hughes Medical Institute researchers, researchers can now reconstruct thousands of genes that are "shredded" into tiny pieces when tissue samples are treated with a chemical fixative and stored in wax a protocol that is usually used to preserve the samples........ ]]> http://medicineworld.org/cancer/lead/10-2008/a-walk-in-the-park-improves-attention.html http://medicineworld.org/cancer/lead/10-2008/a-walk-in-the-park-improves-attention.html Wed, 15 Oct 2008 23:54:49 GMT For children with Attention Deficit Hyperactivity Disorder (ADHD) tasks that require concentration such as doing homework or taking a test can be very difficult. A simple, inexpensive remedy may be a "dose of nature". A study conducted at the University of Illinois shows that children with ADHD demonstrate greater attention after a 20-minute walk in a park than after a similar walk in a downtown area or a residential neighborhood........ ]]> http://medicineworld.org/cancer/lead/10-2008/high-school-social-skills-predict-better-earnings.html http://medicineworld.org/cancer/lead/10-2008/high-school-social-skills-predict-better-earnings.html Wed, 15 Oct 2008 23:54:49 GMT Ten years after graduation, high-school students who had been rated as conscientious and cooperative by their teachers were earning more than classmates who had similar test scores but fewer social skills, said a new University of Illinois study. The study's findings challenge the idea that racial, ethnic, and socioeconomic gaps in educational attainment and earnings can be narrowed solely by emphasizing cognitive skills, said Christy Lleras, a University of Illinois assistant professor of human and community development........ ]]> http://medicineworld.org/cancer/lead/10-2008/searching-the-internet-increases-brain-function.html http://medicineworld.org/cancer/lead/10-2008/searching-the-internet-increases-brain-function.html Wed, 15 Oct 2008 23:54:49 GMT UCLA researchers have observed that for computer-savvy middle-aged and elderly adults, searching the Internet triggers key centers in the brain that control decision-making and complex reasoning. The findings demonstrate that Web search activity may help stimulate and possibly improve brain function........ ]]> http://medicineworld.org/cancer/lead/10-2008/why-do-women-get-more-cavities-than-men.html http://medicineworld.org/cancer/lead/10-2008/why-do-women-get-more-cavities-than-men.html Wed, 15 Oct 2008 23:54:49 GMT Reproduction pressures and rising fertility explain why women suffered a more rapid decline in dental health than did men as humans transitioned from hunter-and-gatherers to farmers and more sedentary pursuits, says a University of Oregon anthropologist. The conclusion follows a comprehensive review of records of the frequencies of dental cavities in both prehistoric and living human populations from research done around the world. A driving factor was dramatic changes in female-specific hormones, reports John R. Lukacs, a professor of anthropology who specializes in dental, skeletal and nutritional issues........ ]]> http://medicineworld.org/cancer/lead/10-2008/not-slow-cognitive-decline-in-alzheimers.html http://medicineworld.org/cancer/lead/10-2008/not-slow-cognitive-decline-in-alzheimers.html Wed, 15 Oct 2008 23:54:49 GMT A clinical trial led by Paul S. Aisen, M.D., professor of neurosciences at the University of California, San Diego School of Medicine, showed that high-dose vitamin B supplements did not slow the rate of cognitive decline in patients with mild to moderate Alzheimer disease. The study would be reported in the October 15 issue of the Journal of the American Medical Association (JAMA)........ ]]> http://medicineworld.org/cancer/lead/10-2008/alzheimers-disease-and-blood-pressure.html http://medicineworld.org/cancer/lead/10-2008/alzheimers-disease-and-blood-pressure.html Wed, 15 Oct 2008 23:54:49 GMT A new study (http://dx.doi.org/10.1016/j.bihy.2008.04.006) published in Bioscience Hypotheses (http://www.elsevier.com/locate/issn/1756-2392), a recently launched Elsevier journal, proposes that some people suffering from Alzheimer's disease experience a reduction in their hypertension because of cognitive decline........ ]]> http://medicineworld.org/cancer/lead/10-2008/how-brain-sees-what-you-do-not-see.html http://medicineworld.org/cancer/lead/10-2008/how-brain-sees-what-you-do-not-see.html Wed, 15 Oct 2008 23:54:49 GMT Blindsight is a phenomenon in which patients with damage in the primary visual cortex of the brain can tell where an object is eventhough they claim they cannot see it. A research team led by Prof. Tadashi Isa and Dr. Masatoshi Yoshida of the National Institute for Physiological Sciences, Japan, provides compelling evidence that blindsight occurs because visual information is conveyed bypassing the primary visual cortex. Japan Science and Technology Agency supported this study. The team reports their finding in the Journal of Neuroscience on Oct 15, 2008........ ]]> http://medicineworld.org/cancer/lead/10-2008/find-genes-for-type-1-diabetes.html http://medicineworld.org/cancer/lead/10-2008/find-genes-for-type-1-diabetes.html Wed, 15 Oct 2008 23:54:49 GMT Genetics scientists have identified two novel gene locations that raise the risk of type 1 diabetes. As they continue to reveal pieces of the complicated genetic puzzle for this disease, the scientists expect to improve predictive tests and devise preventive strategies. "As we add to our knowledge of the biology of type 1 diabetes and better understand details of the disease's genetic risk, we will be able to develop better diagnostic tests that meaningfully predict who will develop diabetes," said study leader Hakon Hakonarson, M.D., Ph.D., director of the Center for Applied Genomics at The Children's Hospital of Philadelphia........ ]]> http://medicineworld.org/cancer/lead/10-2008/a-low-cholesterol-diet-leaves-a-bitter-taste.html http://medicineworld.org/cancer/lead/10-2008/a-low-cholesterol-diet-leaves-a-bitter-taste.html Wed, 15 Oct 2008 23:54:49 GMT One role for the proteins on the tongue that sense bitter tasting substances, type 2 taste receptors (T2Rs), is to limit ingestion of these substances, as a large number of natural bitter compounds are known to be toxic. T2Rs are also found in the gut, and it has been suggested that there they have a similar role to their function in the mouth (i.e., they might limit intestinal toxin absorption). Data to support this idea has now been generated in mice by Timothy Osborne and his colleagues, at the University of California, Irvine........ ]]> http://medicineworld.org/cancer/lead/10-2008/communication-between-neurons-and-muscle-cells.html http://medicineworld.org/cancer/lead/10-2008/communication-between-neurons-and-muscle-cells.html Wed, 15 Oct 2008 23:54:49 GMT You can't raise a finger without your brain directing muscle cells, and researchers have figured out another reason that commonly works so well. A neuron sends a message, or neurotransmitter, to the muscle cell to tell it what to do. To get the message, the receiving cell must have a receptor. Oddly, the unstable protein rapsyn is responsible for anchoring the receptor so it's properly positioned to catch the message........ ]]> http://medicineworld.org/cancer/lead/10-2008/steroid-treatment-offers-no-benefit-in-preemies.html http://medicineworld.org/cancer/lead/10-2008/steroid-treatment-offers-no-benefit-in-preemies.html Wed, 15 Oct 2008 23:54:49 GMT Results of a multicenter study led by Johns Hopkins Children's Center challenge the longstanding practice of treating premature babies with hydrocortisone, a steroid believed to fight inflammation and prevent lung disease. The scientists observed that such therapy offers little or no benefit and that low cortisol levels are not even necessarily harmful. High cortisol levels, conversely, appeared to increase the risk of dangerous bleeding in the brain and require that babies be monitored aggressively to ward off life-threatening complications, as per the study reported in the recent issue of Pediatrics........ ]]> http://medicineworld.org/cancer/lead/10-2008/human-mind-and-future-infrastructure-systems.html http://medicineworld.org/cancer/lead/10-2008/human-mind-and-future-infrastructure-systems.html Wed, 15 Oct 2008 23:54:49 GMT The National Science Foundation (NSF) Office of Emerging Frontiers in Research and Innovation (EFRI) has announced 12 grants for fiscal year 2008, awarding a total of $23,779,056 over four years to 54 researchers representing 20 institutions. Interdisciplinary teams will pursue transformative, fundamental research in two areas of great promise: understanding the brain and how its abilities may be used through cognitive optimization and prediction; and developing ways to make complex, interdependent infrastructure systems more resilient and sustainable........ ]]>
