ROCHESTER, Minn. - A Mayo Clinic case study finds Botox may offer new hope to patients suffering disabling low cerebrospinal fluid headaches. The successful treatment also offers new insight into Botox and headache treatment generally. The case study was presented March 13th, 2011 at the American Academy of Neurology meeting in Hawaii. Low CSF pressure headaches are caused by an internal spinal fluid leak. The pain can range from slight to disabling. The headaches are most commonly triggered by a lumbar puncture. The pain is caused as fluid leaks out and the brain ...

Palo Alto, CA—Scientists have known for decades that black carbon aerosols add to global warming. These airborne particles made of sooty carbon are believed to be among the largest man-made contributors to global warming because they absorb solar radiation and heat the atmosphere. New research from Carnegie's Long Cao and Ken Caldeira, along with colleagues George Ban-Weiss and Govindasamy Bala, quantifies how black carbon's impact on climate depends on its altitude in the atmosphere. Their work, published online by the journal Climate Dynamics, could have important implications ...

Some of the Pharmaceuticals intended for the treatment of minor illnesses of astronauts in space may require special packaging and reformulation to remain stable for long periods in the space environment. That's according to Dr. Putcha and her colleagues from NASA, Johnson Space Centre. Their findings, published online in The AAPS Journal suggest that some of the pharmaceuticals stored on space flights may have shorter shelf-life than they do on Earth. Pharmaceuticals used on space flights are packed and dispensed in special flight-certified containers and stored in ...

With obesity rates soaring, the government has been promoting nudge – a strategy that does not tell people how to live but encourages them to make healthy choices in respect of diet and exercise. Experts on bmj.com this week go head to head over whether nudge is an effective way to tackle obesity. Professor Tim Lang and Dr Geof Rayner, both from the Centre for Food Policy at City University in London, say that nudge is not new and that it is "a smokescreen for, at best, inaction and, at worst, publicly endorsed marketing." They argue that the nudging strategy portrays ...

Two small randomised trials published on bmj.com today suggest that closed loop insulin delivery (also known as an artificial pancreas) may improve overnight blood glucose control and reduce the risk of nocturnal hypoglycaemia (a sudden drop in blood glucose levels during the night) in adults with type 1 diabetes. The number of people with type 1 diabetes is increasing at a rate of 3% per year, particularly in white northern European populations. Lifelong insulin therapy is needed to control blood glucose levels, but the risk of hypoglycaemia remains a major challenge, ...

Writing in BioEssays, cancer scientists Ana Soto and Carlos Sonnenschein pit their controversial Tissue Organization Field Theory (TOFT) of the origin of cancer against the widely accepted Somatic Mutation Theory (SMT) in what is believed to be the first time the two theories have formally opposed each other – championed by authors from opposite sides of the debate – in a common forum for discussion. Soto and Sonnenschein, from Tufts University, argue that SMT, which is based on the accumulation of genetic mutations in cells, not only fails to provide an explanation for ...

Scientists have discovered a method to control the gas-phase selective catalytic combustion of methane, so finely that if done at room temperature the reaction produces ethylene, while at lower temperatures it yields formaldehyde. The process involves using gold dimer cations as catalysts — that is, positively charged diatomic gold clusters. Being able to catalyze these reactions, at or below room temperature, may lead to significant cost savings in the synthesis of plastics, synthetic fuels and other materials. The research was conducted by scientists at the Georgia ...

Montreal, April 14, 2011 – An international consortium of scientists, including major contributions from the Montreal Heart Institute, demonstrates that the "one-size fits all" strategy of uniformly doubling the dose of an antiplatelet drug, clopidogrel, for patients with high on-treatment platelet reactivity does not reduce the incidence on death, heart attacks and stent thrombosis after percutaneous coronary intervention (PCI). The results of the GRAVITAS trial conducted to determine whether high-dose clopidogrel is superior to standard-dose therapy for the prevention ...

The idea of probing the body's interior with radiation stretches back to experiments with X rays in the 1800s, but more than a century later, images taken with radiological scans still are not considered reliable enough to, for example, serve as the sole indicator of the efficacy of a cancer treatment. Lisa Karam, a biochemist at the National Institute of Standards and Technology (NIST) and a few dozen of her colleagues across North America have set out to change that. The group of radiology specialists from a number of institutions has recently published* a pair of papers ...

Philadelphia, PA, 14 April 2011 - The judgments we make about the intimacy of other couples' relationships appear to be influenced by the brain chemical serotonin, reports a new study published in Biological Psychiatry. Healthy adult volunteers, whose levels of serotonin activity had been lowered, rated couples in photos as being less intimate and less romantic than volunteers with normal serotonin activity. The approach involved giving amino acid drinks to two groups of volunteers in order to manipulate blood concentrations of the amino acid tryptophan, which is a ...

In tests of four different types of new refrigerators, National Institute of Standards and Technology (NIST) researchers found that ice makers increased rated energy consumption by 12 to 20 percent. About three-fourths of that additional energy cost is due to the electric heaters used to release the ice bits from the molds. With only one-fourth of the extra energy actually used to cool and freeze water, "there are substantial opportunities for efficiency improvements merely by optimizing the operations of the heaters associated with the ice makers" or by introducing a ...

Washington, D.C., 14 April, 2011 – During the winter of 2008�, a three-week armed conflict in the south of Israel and the Gaza Strip named "Operation Cast Lead" resulted in hundreds of rocket and mortar attacks on Israeli civilian populations. During this time children and their families spent hours and days in shelters amid threats to their survival. Although the psychological effects of children's health are well-documented, local resources aimed at alleviating the negative outcomes of mass trauma are often overwhelmed. In the face of human-made or natural ...

MADISON – A little information can go a surprisingly long way when it comes to understanding rodent-borne infectious disease, as shown by a new study led by John Orrock from the University of Wisconsin-Madison. The researchers studied wild deer mouse populations on the Channel Islands off the southern coast of California, which carry a variant of hantavirus called Sin Nombre virus. In their study appearing in the May issue of the journal American Naturalist, they show that just three ecological factors – rainfall, predator diversity, and island size and shape – can ...

This release is available in German. This contradicts the common understanding that word-order develops in accordance with a set of universal rules, applicable to all languages. Researchers have concluded that languages do not primarily follow innate rules of language processing in the brain. Rather, sentence structure is determined by the historical context in which a language develops. Linguists want to understand how languages have become so diverse and what constraints language evolution is subject to. To this end, they search for recurring patterns in language ...

EAST PROVIDENCE, R.I. – More intensive or family-based HIV prevention interventions may be needed to encourage juvenile offenders to use condoms and stop engaging in risky sexual behavior, say researchers from the Bradley Hasbro Children's Research Center (BHCRC). Juvenile offenders are at increased risk for contracting HIV and other sexually transmitted diseases because they tend to have sex at earlier ages, have more sexual partners, use condoms less frequently and engage in more substance and alcohol use. Young offenders who are court-monitored but living at home ...
