New Brain Receptor Identified For Date-Rape Drug
Date: Jul-05-2012Researchers are closer to understanding the biology behind GHB, a transmitter substance in the brain, best known in its synthetic form as the illegal drug fantasy. These findings have just been published in the scientific journal PNAS. In the 1960s, gamma-hydroxybutyric acid (GHB) was first discovered as a naturally occurring substance in the brain. Since then it has been manufactured as a drug with a clinical application and has also developed a reputation as the illegal drug fantasy and as a date rape drug. Its physiological function is still unknown...
Improved Laparoscopy Offers Multiple Perspectives
Date: Jul-05-2012Surgeons given their own view of a laparoscopic task, rather than a shared one, can work more efficiently and accurately, a small new study suggests. Findings from "proof of concept" experiments appear in the Journal of Laparoendoscopic and Advanced Surgical Techniques. What makes laparoscopic surgery "minimally invasive" - instruments enter the patient through narrow tubes - also makes it visually constraining. As they work on different tasks, surgeons all see the same view...
Swallowing Disorders After Stroke Alleviated By Electrical Brain Stimulation
Date: Jul-05-2012After stroke, patients often suffer from dysphagia, a swallowing disorder that results in greater healthcare costs and higher rates of complications such as dehydration, malnutrition, and pneumonia. In a new study published in the July issue of Restorative Neurology and Neuroscience, researchers have found that transcranial direct current stimulation (tDCS), which applies weak electrical currents to the affected area of the brain, can enhance the outcome of swallowing therapy for post-stroke dysphagia...
New Insights From The Front Lines Of Battle Against Malaria
Date: Jul-05-2012In most comprehensive review of a decade of data researchers confirm indoor insecticide treatments, dramatically reduce malaria; study finds world's best drug still effective in African malaria 'hot zone' while researchers question for how long A pair of provocative studies in the July 2012 issue of The American Journal of Tropical Medicine and Hygiene (AJTMH) provides a window into the intense ground war now underway against malaria. In one review, researchers offer new evidence supporting indoor insecticide spraying as a way to dramatically reduce malaria deaths...
Charting Autism's Neural Circuitry
Date: Jul-05-2012Deleting a single gene in the cerebellum of mice can cause key autistic-like symptoms, researchers have found. They also discovered that rapamycin, a commonly used immunosuppressant drug, prevented these symptoms. The deleted gene is associated with Tuberous Sclerosis Complex (TSC), a rare genetic condition. Since nearly 50 percent of all people with TSC develop autism, the researchers believe their findings will help us better understand the condition's development...
Palaeopathologists Search For Ancient Syphilis DNA In Newborns
Date: Jul-05-2012The ancient bones of newborns are very useful to recover the ancient DNA of the bacteria causing syphilis, the Treponema pallidum pallidum. This is the conclusion reached by a study led by Universitat Autonoma de Barcelona (UAB), which was able to obtain the genetic material from the bacteria in more than one individual, in what is considered to be the oldest case known to date. Several previous intents had only achieved to yield this material in one occasion and from only one individual...
Risk Of Bladder Cancer May Increase With Some Diabetes Drugs
Date: Jul-05-2012An increased risk of bladder cancer is linked to the use of pioglitazone, a medication commonly used to treat type 2 diabetes, according to a new study published in CMAJ (Canadian Medical Association Journal). People with type 2 diabetes are at risk of several types of cancer, including a 40% increased risk of bladder cancer, compared to people without diabetes. Previous studies have shown a higher incidence of bladder cancer in people taking pioglitazone, a type of thiazolidinedione...
Children's Healthcare Spending Rising Faster Than Adults
Date: Jul-05-2012Teens See Highest Rate of Per Capita Spending Growth; Children over Nine See Increases in Prescription Drug Expenditures; Use of Mental Health Services Grows Spending on health care for children grew faster than spending for adults between 2007 and 2010 due to increasing prices for all categories of goods and services, finds a new report from the Health Care Cost Institute (HCCI)...
Development Of New Vaccine For 1 Of The 7 Strains Of The Dreaded Foot And Mouth Disease
Date: Jul-05-2012One of the most economically devastating diseases in the world for those who raise cows, sheep, pigs, goats, deer and other cloven-hoofed animals is foot and mouth Disease (FMD). This incredibly contagious and fast-spreading disease causes fever, blisters on the feet and mouth (hence the name), loss of appetite, drooling, and lameness. Most herds affected are culled, as in the case of the 2001 outbreak in Great Britain when over 10 million animals had to be destroyed...
Bullying In Schools Greater For Students With 'Observable' Disabilities
Date: Jul-05-2012Students receiving special-education services for behavioral disorders and those with more obvious disabilities are more likely to be bullied than their general-education counterparts - and are also more likely to bully other students, a new study shows. The findings, published in the Journal of School Psychology, highlight the complexity of bullying's nature and the challenges in addressing the problem, said lead author Susan Swearer, professor of school psychology at the University of Nebraska-Lincoln...
