| Blood Pressure Drug Prazosin Effective for Treating PTSD-Related Nightmares Posted: 06 Mar 2012 06:55 AM PST Mayo Clinic researchers this week will announce the use of the blood pressure drug prazosin as an effective treatment to curb post-traumatic stress disorder (PTSD)-related nightmares. In a presentation during the 20th European Congress of Psychiatry in Prague, Mayo Clinic psychiatrists will present a systematic literature review of prazosin in the treatment of nightmares. Researchers investigated 12 prazosin studies, four of which were randomized controlled trials. |
| Tonsils Make T-Cells, Too, Ohio State Study Shows Posted: 06 Mar 2012 06:48 AM PST A new study provides evidence that a critical type of immune cell can develop in human tonsils. The cells, called T lymphocytes, or T cells, have been thought to develop only in the thymus, an organ of the immune system that sits on the heart. The study, led by researchers at the Ohio State University Comprehensive Cancer Center – Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC – James), could improve the understanding of T-cell cancers and autoimmune diseases, and how stem-cell transplantation is done. |
| Physiotherapy and physical exercise improve the general states of breast cancer survivors Posted: 06 Mar 2012 06:34 AM PST University of Granada researchers, in collaboration with the University Hospital Virgen de las Nieves, Granada, Spain, have developed a physiotherapy and physical exercise program that considerably reduces muskuloskeletal pain in breast cancer survivors. A study recently published has demonstrated that physical therapy is very effective in reducing fatigue and α-amylase, thus improving neck mobility, muscle strength and general state in breast cancer survivors. |
| Posted: 06 Mar 2012 06:26 AM PST Aluminum has long been the poster child of recycling. About half of all aluminum used in the United States is now recycled, and this recycling has clear and dramatic benefits: Pound for pound, it takes anywhere from nine to 18 times as much energy to produce aluminum from raw ore as from recycled material. |
| New Method For Estimating Parameters May Boost Biological Models Posted: 06 Mar 2012 06:15 AM PST Modeling biological systems can provide key insights for scientists and medical researchers, but periodic cycles that repeat themselves – so-called oscillatory systems – pose some key challenges. Researchers at North Carolina State University have developed a new method for estimating the parameters used in such models – which may advance modeling in research areas ranging from cancer to fertility. |
| Visinin-Like Protein 1, VILIP-1:New Alzheimer’s marker strongly predicts mental decline Posted: 05 Mar 2012 07:31 PM PST A new marker of Alzheimer’s disease, visinin-like protein 1 (VILIP-1), can predict how rapidly a patient’s memory and other mental abilities will decline after the disorder is diagnosed, researchers at Washington University School of Medicine in St. Louis have found. |
| Ability to detect light could have evolved before anything like an eye Posted: 05 Mar 2012 12:53 PM PST New research from the University of California shows how the ability to detect light could have evolved before anything like an eye. As published today (March 5) in the journal BMC Biology, the research is based on the stinging mechanism in the tiny, brainless and eyeless freshwater polyp Hydra magnipapillata. Part of a group of animals called cnidarians that includes sea anemones, corals and jellyfish, a hydra is essentially a mouth surrounded by tentacles armed with stinging cells, or cnidocytes. |
| New nanoglue is thin and supersticky Posted: 05 Mar 2012 12:48 PM PST Engineers at the University of California, Davis, have invented a superthin “nanoglue” that could be used in new-generation microchip fabrication. “The material itself (say, semiconductor wafers) would break before the glue peels off,” said Tingrui Pan, professor of biomedical engineering. He and his fellow researchers have filed a provisional patent. |
| Perception And Preference May Have Genetic Link To Obesity Posted: 05 Mar 2012 12:40 PM PST About five years ago, animal studies first revealed the presence of entirely novel types of oral fat sensors or receptors on the tongue. Prior to this time, it was believed that fats were perceived only by flavor and texture cues. With this new information, “everything that we thought we knew about fat perception got turned on its head,” said Beverly Tepper, a professor in the Department of Food Science at Rutgers School of Environmental and Biological Sciences. |
| A Traffic Jam of Quantum Particles Posted: 05 Mar 2012 12:26 PM PST LMU/MPQ-scientists discover surprising transport phenomena in ultracold quantum many body systems. Transport properties such as thermal or electrical conductivity are of great importance for technical applications of materials. In particular the electrical conductivity stems from the behaviour of the electrons in the solid and is very difficult to predict. This is true especially in the case of strongly correlated electrons, when the position and the dynamics of each single electron is strongly influenced by the behaviour of all other electrons. |
| New approach to stroke therapy: Toxic gas protects brain function in animal model Posted: 05 Mar 2012 12:16 PM PST LMU researchers developed a new strategy for the treatment of stroke, which could help to improve blood flow to ischemic brain. Strokes are due to a localized reduction in the blood supply to the brain, mainly due to the blockage of a vessel by a blood clot. |
| Hyperactivity: increased prevalence of children with ADHD and the use of stimulants Posted: 05 Mar 2012 11:24 AM PST A new study from the Université de Montréal shows an increase in prevalence of Canadian children diagnosed with attention-deficit hyperactivity disorder (ADHD) and in the use of medications associated with ADHD in school-age children. |
| Next-generation DNA sequencing to improve diagnosis for muscular dystrophy Posted: 05 Mar 2012 09:49 AM PST Scientists at The University of Nottingham have used a revolutionary new DNA-reading technology for a research project that could lead to correct genetic diagnosis for muscle-wasting diseases. |
| Better, Cheaper Detection of Hazardous Gases Posted: 05 Mar 2012 09:43 AM PST Fazel Yavari has developed a new sensor to detect extremely small quantities of hazardous gases. Made from a 3-D foam of the world’s thinnest material, graphene, this sensor is durable, inexpensive to make, and opens the door to a new generation of gas detectors for use by bomb squads, defense and law enforcement officials, as well as applications in industrial settings. |
| Spider silk conducts heat as well as metals Posted: 05 Mar 2012 09:29 AM PST Xinwei Wang had a hunch that spider webs were worth a much closer look. So he ordered eight spiders - Nephila clavipes, golden silk orbweavers - and put them to work eating crickets and spinning webs in the cages he set up in an Iowa State University greenhouse. |
| Posted: 05 Mar 2012 09:18 AM PST Aging does not appear to be a factor in poor sleep, a new study by Perelman School of Medicine at the University of Pennsylvania shows. In fact, subjective sleep quality seems to improve over a lifetime, with the fewest complaints coming from people in their 80s. The new study is published in the journal SLEEP. |
| Study shows dry storage a viable option for biospecimens Posted: 05 Mar 2012 08:38 AM PST A University of Colorado Cancer Center pilot study has discovered that the quality of dehydrated RNA from human cancer biospecimens compares favorably to those stored in ultra-low-temperature (minus-80 centigrade) freezers. The study has been directed by Professor William Robinson, MD, PhD, Medical Oncology, in collaboration with David Turnquist, associate vice chancellor, Facilities Management. |
| Scientists revolutionise electron microscope Posted: 05 Mar 2012 08:33 AM PST Researchers at the University of Sheffield have revolutionised the electron microscope by developing a new method which could create the highest resolution images ever seen. For over 70 years, transmission electron microscopy (TEM), which `looks through´ an object to see atomic features within it, has been constrained by the relatively poor lenses which are used to form the image. |
| A novel radiotherapy approach targets only neck areas at a higher risk of cancer recurrence Posted: 05 Mar 2012 08:26 AM PST Researchers at the University of Granada and the university hospital Virgen de las Nieves in Granada have developed a new radiotherapy technique that is much less toxic than that traditionally used and only targets cancerous tissue. This new protocol provides a less invasive but equally efficient cancer postoperative treatment for cases of cancer of the oral cavity and pharynx. |
| Kids' Abnormal Breathing During Sleep Linked to Increased Risk for Behavioral Difficulties Posted: 05 Mar 2012 08:17 AM PST A study of more than 11,000 children followed for over six years has found that young children with sleep-disordered breathing are prone to developing behavioral difficulties such as hyperactivity and aggressiveness, as well as emotional symptoms and difficulty with peer relationships, according to researchers at Albert Einstein College of Medicine of Yeshiva University. Their study, the largest and most comprehensive of its kind, published online today in the journal Pediatrics. |
