Others are clearly more cautious and focus primarily on safety when investing and for other business activities. Scientists from the University of Bonn in cooperation with colleagues from the University of Zurich studied the attitudes towards risk in a group of 56 subjects. They found that in people who preferred safety, certain regions of the brain show a higher level of activation when they are confronted with quite unforeseeable situations. In addition, they do not distinguish as clearly as risk takers whether a situation is more or less risky than expected. The results have just been published in the renowned Journal of Neuroscience. http://medicalxpress.com/news/2012-11-aversity-visible-brain.html Neuroscience Mon, 26 Nov 2012 13:19:58 EST news273158382 Life expectancy in AIDS-hit South Africa has shot up by six years to 60 over the past few years, thanks to life prolonging anti-retroviral (ARVs) treatment, a demographer said Thursday. http://medicalxpress.com/news/2012-10-life-safrica.html Health Thu, 18 Oct 2012 14:31:54 EST news269789505 (HealthDay)—Kidney transplant patients who receive mammalian target of rapamycin (mTOR) inhibitors after transplant have a greater probability of death or transplant failure than patients receiving calcineurin inhibitors, according to a study published online Oct. 1 in the American Journal of Transplantation. http://medicalxpress.com/news/2012-10-drug-class-linked-worse-outcomes.html Surgery Sun, 14 Oct 2012 14:30:01 EST news269414813 (HealthDay)—You may think your toddler is just playing in the sand box, but she may really be conducting a sophisticated scientific experiment and learning something new every time she pours out another scoop of sand, new research suggests. http://medicalxpress.com/news/2012-09-science.html Psychology & Psychiatry Thu, 27 Sep 2012 17:59:46 EST news267987571 Doctors who experience a gut feeling about serious illness when treating a child in primary care should take action upon this feeling and not ignore it, a study published today in BMJ suggests. http://medicalxpress.com/news/2012-09-doctors-gut.html Health Tue, 25 Sep 2012 18:30:01 EST news267808377 A new guideline released by the American Academy of Neurology may help doctors in making the diagnosis of Creutzfeldt-Jakob disease.

Researchers from the Institute of Social and Preventive Medicine at the University of Zurich demonstrate that for ratings ranging from "excellent," "good," "fair," and "poor" to "very poor," the risk of mortality increases steadily – independently of such known risk factors as smoking, low education levels or pre-existing diseases. http://medicalxpress.com/news/2012-02-.html Health Thu, 09 Feb 2012 17:00:16 EST news248007850 New research presented at the 2012 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS) highlights the benefits of total knee replacement (TKR) in elderly patients with osteoarthritis, including a lower probability of heart failure and mortality. http://medicalxpress.com/news/2012-02-knee-patient-mortality-heart-failure.html Arthritis & Rheumatism Tue, 07 Feb 2012 10:58:48 EST news247834718 Among patients with moderate to severe psoriasis, treatment options that are most compatible with their personal and professional life appear to be most important, and treatment location appears more important than probability and magnitude of treatment outcome, according to a report in the November issue of Archives of Dermatology. http://medicalxpress.com/news/2011-11-importance-treatment-outcomes-varies-patients.html Diseases, Conditions, Syndromes Mon, 21 Nov 2011 16:00:08 EST news241102663 The olfactory sensory neurons in the nasal mucosa perceive the myriad smells in the air with the aid of odorant receptors. Each sensory neuron chooses one and only one receptor gene for expression. The probability that a particular receptor gene is chosen for expression determines how many olfactory sensory neurons in total produce this receptor type. Scientists from the Max Planck Institute of Biophysics in Frankfurt have unveiled an aspect of how the probability of the choice of an odorant receptor gene is regulated in olfactory sensory neurons. Regulatory elements in the genome regulate the probability of the choice of individual odorant receptor genes within a gene cluster. These elements act as on-off-switches for gene choice, but they do not regulate the number of receptor molecules that are produced by a cell once a particular gene is chosen for expression. http://medicalxpress.com/news/2011-11-gene-odorant-receptors.html Genetics Fri, 11 Nov 2011 12:52:29 EST news240238340 During a decade of receiving mammograms, more than half of cancer-free women will be among those summoned back for more testing because of false-positive results, and about one in 12 will be referred for a biopsy. http://medicalxpress.com/news/2011-10-high-false-positives-annual-mammogram.html Cancer Mon, 17 Oct 2011 17:00:02 EST news238080960 Participants in a congress were asked to wear a tag for two days in order to study their movements and interactions within a population. The data, collected by a French-Italian team including researchers from CNRS, Inserm, the Universite Claude Bernard Lyon and the CHU de Lyon, makes it possible to envisage the simulation of the spread of infection risks within a population, or even the optimization of the response to the expansion of an epidemic. The results of this work are published on 11 July in BMC Medicine. http://medicalxpress.com/news/2011-07-tags-epidemics.html Diseases, Conditions, Syndromes Fri, 22 Jul 2011 10:37:13 EST news230549818
