Regular Exercise May Increase Pain Tolerance
Date: May-20-2012Stories of athletes bravely "playing through the pain" are relatively common and support the widespread belief that they experience pain differently than non-athletes. Yet, the scientific data on pain perception in athletes has been inconsistent, and sometimes contradictory. Investigators from the University of Heidelberg have conducted a meta-analysis of available research and find that in fact, athletes can indeed tolerate a higher level of pain than normally active people. However, pain threshold, the minimum intensity at which a stimulus is perceived as painful, did not differ in athletes...
Genetic Test May Predict Risk Of Schizophrenia
Date: May-19-2012Researchers at the Indiana University School of Medicine have developed a test that can predict how likely an individual is to develop schizophrenia. The scientists combined data from several different types of studies in order to identify and prioritize a group of genes most associated with the disease. Combined, these genes can generate a score, and determine whether an individual is at lower or higher risk of developing schizophrenia. The study, which was conducted along with a group of national and international collaborators, is published online in the journal Molecular Psychiatry. In...
Autism, Obesity And Schizophrenia Gene Isolated
Date: May-19-2012The size of a baby's head is often related to neurological disorders, such as autism - which affects 1 in 88 children. Now, researchers at Duke University Medical Center have identified genes responsible for head size at birth by inserting human genes into zebrafish. The study is published online in the journal Nature. Nicholas Katsanis, Ph.D., Jean and George Brumley Jr. M.D., Professor of Developmental Biology, and Professor of Pediatrics and Cell Biology (both at Duke University Medical Center, explained: "In medical research, we need to dissect events in biology so we can understand the...
Renal Denervation Lowers Blood Pressure In Kidney Disease Patients
Date: May-19-2012Disrupting certain nerves in the kidneys can safely and effectively lower blood pressure in patients with chronic kidney disease (CKD) and hypertension, according to a study appearing in an upcoming issue of the Journal of the American Society of Nephrology (JASN). The findings indicate that the procedure might improve CKD patients' heart health. Overactivity of neurons in the sympathetic - or fight or flight - nervous system is very common in patients with CKD. It not only contributes to high blood pressure and heart problems in these patients, but also to worsening of their kidney disease. A...
Hormone-Depleting Drug Shows Promise Against Localized High-Risk Prostate Tumors
Date: May-19-2012A hormone-depleting drug approved last year for the treatment of metastatic prostate cancer can help eliminate or nearly eliminate tumors in many patients with aggressive cancers that have yet to spread beyond the prostate, according to a clinical study to be presented at the annual meeting of the American Society of Clinical Oncology (ASCO), June 1-5, in Chicago. The phase II clinical trial, led by investigators at Dana-Farber Cancer Institute and other research centers, examined the use of the drug abiraterone acetate (Zytiga(R)) in combination with prednisone and surgery in 58 men with...
Distraction As Pain Relief
Date: May-19-2012Mental distractions make pain easier to take, and those pain-relieving effects aren't just in your head, according to a report published online in Current Biology, a Cell Press publication. The findings based on high-resolution spinal fMRI (functional magnetic resonance imaging) as people experienced painful levels of heat show that mental distractions actually inhibit the response to incoming pain signals at the earliest stage of central pain processing. "The results demonstrate that this phenomenon is not just a psychological phenomenon, but an active neuronal mechanism reducing the amount...
It's Not Just What You Eat, When You Eat Matters Too
Date: May-19-2012When it comes to weight gain, when you eat might be at least as important as what you eat. That's the conclusion of a study reported in the Cell Press journal Cell Metabolism published early online. When mice on a high-fat diet are restricted to eating for eight hours per day, they eat just as much as those who can eat around the clock, yet they are protected against obesity and other metabolic ills, the new study shows. The discovery suggests that the health consequences of a poor diet might result in part from a mismatch between our body clocks and our eating schedules. "Every organ has a...
OSHA Regulations Can Be Good For Workers' Health, Save Lives
Date: May-19-2012Research published in Science sheds light on a hot-button political issue: the role and effectiveness of government regulation. Does it kill jobs or protect the public? The new study, co-authored by Harvard Business School Professor Michael Toffel, Professor David Levine of the Haas School of Business at the University of California, Berkeley, and Boston University doctoral student Matthew Johnson, examines workplace safety inspections conducted by California's Division of Occupational Safety and Health (Cal/OSHA). The authors carried out the first evaluation of a "clinical trial" of the...
For Chronic Kidney Disease Patients, One Type Of Open Heart Surgery Is Safer Than The Other

Controlling Bacterial Population Density Within Infections
Date: May-19-2012Scientists at The University of Nottingham have opened the way for more accurate research into new ways to fight dangerous bacterial infections by proving a long-held theory about how bacteria communicate with each other. Researchers in the University's School of Molecular Medical Sciences have shown for the first time that the effectiveness of the bacteria's communication method, a process called 'quorum sensing', directly depends on the density of the bacterial population. This work will help inform wider research into how to stop bacteria talking to each other with the aim of switching off...
