Traumatized people who take a class of common blood pressure medications tend to have less severe post-traumatic stress symptoms, researchers have found. The finding suggests that ACE (angiotensin converting enzyme) inhibitors or ARBs (angiotensin receptor blockers) could be valuable tools for treating or preventing post-traumatic stress disorder. The results were published online May 1 in the Journal of Clinical Psychiatry. "These results are particularly exciting because it's the first time ACE inhibitors and ARBs have been connected to PTSD, and it gives us a ...

WINSTON-SALEM, N.C. – May 1, 2012 – With nearly one-third of American children being overweight or obese, doctors agree that there is an acute need for more effective treatments. In many weight management programs, the dropout rate can be as high as 73 percent, and even in successful programs, the benefits are usually short term. Although family-based approaches to pediatric obesity are considered the gold standard of treatment, theories of the family and how it functions have not been incorporated into effective interventions, according to a study published in the May ...

New York, NY(May 1, 2012) – Large majorities of older Americans experience significant and troubling gaps in their primary care, according to a new national survey, "How Does It Feel?

CORVALLIS, Ore. – It takes a gutsy insect to sneak up on a huge dinosaur while it sleeps, crawl onto its soft underbelly and give it a bite that might have felt like a needle going in – but giant "flea-like" animals, possibly the oldest of their type ever discovered, probably did just that. And a few actually lived through the experience, based on the discovery by Chinese scientists of remarkable fossils of these creatures, just announced in Current Biology, a professional journal. These flea-like animals, similar but not identical to modern fleas, were probably 10 ...

Belmont, MA - Researchers at Harvard-affiliated McLean Hospital have shown a new category of "green" nanoparticles comprised of a non-toxic, protein-based nanotechnology that can non-invasively cross the blood brain barrier and is capable of transporting various types of drugs. In an article published May 1, 2012 online in PLoS ONE, Gordana Vitaliano, MD, director of the Brain Imaging NaNoTechnology Group at the McLean Hospital Imaging Center, reported that clathrin protein, a ubiquitous protein found in human, animal, plant, bacteria and fungi cells, can been modified ...

To better understand the signaling pathways active in sarcomas, researchers at Moffitt Cancer Center used state-of-the-art mass spectrometry-based proteomics to characterize a family of protein enzymes that act as "on" or "off" switches important in the biology of cancer. The tyrosine kinases they identified, the researchers said, could act as "drivers" for the growth and survival of sarcomas. Sarcomas are relatively rare forms of cancer. In contrast to carcinomas, which arise from epithelial cells (in breast, colon and lung cancers, for example), sarcomas are tumors ...

Infants born to women who used the anti-HIV drug tenofovir as part of an anti-HIV drug regimen during pregnancy do not weigh less at birth and are not of shorter length than infants born to women who used anti-HIV drug regimens that do not include tenofovir during pregnancy, according to findings from a National Institutes of Health network study. However, at 1 year of age, children born to the tenofovir-treated mothers were slightly shorter and had slightly smaller head circumference—about 1 centimeter each, on average—than were infants whose mothers did not take tenofovir. ...

Researchers at Mount Sinai School of Medicine have gained insight into the mechanism by which a pathological brain protein called tau contributes to the progression of Alzheimer's disease (AD) and other neurodegenerative disorders. This finding, published in the most recent issue of the Journal of Biological Chemistry, may provide the basis for future investigations on how to prevent tau from damaging brain circuits involved in cognitive function. Previous studies have shown that the abnormal folding, or misfolding, and buildup of tau are key neuropathological features ...

Low dose whole body CT is nearly four times better than radiographic skeletal survey, the standard of care in the U.S., for determining the extent of disease in patients with multiple myeloma, a new study shows. The study, conducted at the University of Maryland in Baltimore, included 51 patients who had both a radiographic skeletal survey as well as a low dose whole body CT examination. The total number of lesions detected in these patients with low dose whole body CT was 968 versus 248 detected by radiographic skeletal survey, said Kelechi Princewill, MD, the lead author ...

Cone beam CT is superior to mutidetector CT for detecting superior semicircular canal dehiscence or the so called third window (a small hole in the bony wall of the inner ear bone that can cause dizziness and hearing loss) and it uses half the radiation dose, a new study shows. The study, conducted in Bruges, Belgium, included 21 patients who had both a cone beam CT and a multidetector CT examination of their right and left temporal bones, said David Volders, MD, one of the authors of the study. Two radiologists reviewed the images from both exams and scored them based ...

ONCOLOGY Lymphoma therapy could deliver a double punch | Back to top B cell lymphomas are a group of cancers of that originate in lymphoid tissue from B cells, the specialized immune cell type that produces antibodies. The development of B cell lymphoma is associated with several known genetic changes, including increased expression of MYC, a transcription factor that promotes cell growth and division. In this issue of the JCI, Andrei Thomas-Tikhonenko and his colleagues at the University of Pennsylvania in Philadelphia report on their studies to better understand the ...

UC Davis researchers have found novel compounds that disrupt the formation of amyloid, the clumps of protein in the brains of people with Alzheimer's disease believed to be important in causing the disease's characteristic mental decline. The so-called "spin-labeled fluorene compounds" are an important new target for researchers and physicians focused on diagnosing, treating and studying the disease. The study, published today in the online journal PLoS ONE, is entitled "The influence of spin-labeled fluorene compounds on the assembly and toxicity of the Aβ peptide." "We ...

Steep rises in taxes on alcohol do not necessarily reduce consumption, according to research funded by the Economic and Social Research Council (ESRC) into the history of intoxicants in 16th and 17th England. Dr Philip Withington at the University of Cambridge has found that affluence rather than poverty has tended to drive consumption levels, especially among the middle classes and higher,even though legislation and enforcement is often focused on the poorer parts of the population. "If alcohol consumption is traditionally an index of affluence, then minimum pricing ...

Everyone wants to present themselves in the best light - especially when it comes to finding a partner. Some rely on supplying honest information about their attributes while others exaggerate for good effect. A new study by researchers at the University of Bristol, published in PNAS, has discovered how male crickets could use similar tactics to attract a mate. Male crickets advertise for mates by singing loud repetitive songs at night. They rub their wings together, setting them into resonant vibration, making a loud and intense sound, which enables the female crickets ...

KANSAS CITY, MO—When stretched out, the genome of a single human cell can reach six feet. To package it all into a tiny nucleus, the DNA strand is tightly wrapped around a core of histone proteins in repeating units—each unit known as a nucleosome. To allow access for the gene expression machinery the nucleosomes must open up and regroup when the process is complete. In the May 1, 2012, issue of Genes & Development, researchers at the Stowers Institute for Medical Research demonstrate how failure to restore order has lasting consequences. During the process of gene ...

CHICAGO – Between 2000 and 2009 in the United States, the annual rate of maternal opiate use increased nearly 5-fold, while diagnosis of the drug withdrawal syndrome among newborns, neonatal abstinence syndrome (NAS), increased almost 3-fold, accompanied by a substantial increase in hospital charges related to NAS, according to a study published online by JAMA. The study is being released early to coincide with its presentation at the Pediatric Academic Societies Annual Meeting. A recent national study indicated that 16.2 percent of pregnant teens and 7.4 percent of ...

New evidence proves humans are continuing to evolve and that significant natural and sexual selection is still taking place in our species in the modern world. Despite advancements in medicine and technology, as well as an increased prevalence of monogamy, research reveals humans are continuing to evolve just like other species. Scientists in an international collaboration, which includes the University of Sheffield, analysed church records of about 6,000 Finnish people born between 1760-1849 to determine whether the demographic, cultural and technological changes ...

MEDFORD/SOMERVILLE, Mass. (April 30, 2012, 3 PM EDT) -- Biomedical engineers at Tufts University's School of Engineering have demonstrated the first all-polymeric bone scaffold material that is fully biodegradable and capable of providing significant mechanical support during repair. The new technology uses micron-sized silk fibers to reinforce a silk matrix, much as steel rebar reinforces concrete. It could improve the way bones and other tissues are repaired following accident or disease. The discovery is reported in the Proceedings of the National Academy of Sciences ...

Even low to moderate levels of exposure to the insecticide chlorpyrifos during pregnancy may lead to long-term, potentially irreversible changes in the brain structure of the child, according to a new brain imaging study by researchers from the Columbia Center for Children's Environmental Health at the Mailman School of Public Health, Duke University Medical Center, Emory University, and the New York State Psychiatric Institute. The changes in brain structure are consistent with cognitive deficits found in children exposed to this chemical. Results of the study appear ...

On 5 and 6 June this year, millions of people around the world will be able to see Venus pass across the face of the Sun in what will be a once-in-a-lifetime experience. It will take Venus about six hours to complete its transit, appearing as a small black dot on the Sun's surface, in an event that will not happen again until 2117. In this month's Physics World, Jay M Pasachoff, an astronomer at Williams College, Massachusetts, explores the science behind Venus's transit and gives an account of its fascinating history. Transits of Venus occur only on the very rare ...
