ATS 2011, DENVER – Hospital patients with pneumonia may be at risk of experiencing sudden cardiac arrest, often with few or no warning signs, according to research from the University of Chicago Medical Center under the auspices of the American Heart Association's Get with the Guidelines project. The results of the study will be presented at the American Thoracic Society's 2011 International Conference in Denver. "We found a compelling signal that some patients with pneumonia may develop cardiac arrest outside of the ICU, without apparent shock or respiratory failure," ...

A team of researchers, led by King's College London and the University of Oxford, have found that a gene linked to type 2 diabetes and cholesterol levels is in fact a 'master regulator' gene, which controls the behaviour of other genes found within fat in the body. As fat plays a key role in susceptibility to metabolic diseases such as obesity, heart disease and diabetes, this study highlights the regulatory gene as a possible target for future treatments to fight these diseases. Published today in Nature Genetics, the study was one part of a large multi-national collaboration ...

Researchers at Hewlett Packard and the University of California, Santa Barbara, have analysed in unprecedented detail the physical and chemical properties of an electronic device that computer engineers hope will transform computing. Memristors, short for memory resistors, are a newly understood circuit element for the development of electronics and have inspired experts to seek ways of mimicking the behaviour of our own brains' activity inside a computer. Research, published today, Monday, 16 May, in IOP Publishing's Nanotechnology, explains how the researchers ...

Bubbles are blocking the current path of one of the most promising high temperature superconducting materials, new research suggests. In a study published today, Monday, 16 may, in IOP Publishing's journal Superconductor Science and Technology, researchers have examined bismuth strontium calcium copper oxide (Bi2Sr2CaCu2Ox, Bi2212) – one of the most promising superconducting materials capable of creating large magnetic fields way beyond the limit of existing magnets – and found that its capabilities are limited by the formation of bubbles during its fabrication process. ...

A team of researchers have found that pre-existing malaria prevents secondary infection by another Plasmodium strain, the parasite responsible for malaria, by restricting iron availability in the liver of the host. This discovery will be published this Sunday, May 15, in Nature Medicine and has important implications for the management and prevention of malaria, a condition which affects millions of individuals worldwide. The study was developed by the team led by researcher Maria M. Mota at Instituto de Medicina Molecular in Lisbon, Portugal, in collaboration with researchers ...

A protective molecule has been identified in the brain which, if used artificially, may prevent brain damage from the likes of stroke, head injury and Alzheimer's. By looking at what happens in the brain after an injury, new research has finally ended speculation over whether a key molecule, 'KCC2' causes brain cell death after an injury or prevents it. The finding, published today (16th May 2011) in The Journal of Physiology now opens the door to the development of artificial forms of the compound which could provide 'neuroprotection' to those who have suffered a brain ...

Gene expression is the process of converting the genetic information encoded in DNA into a final gene product such as a protein or any of several types of RNA. Scientists have long thought that the gene programs regulated by different physiological processes throughout the body are robustly pre-determined and relatively fixed for every specialized cell. But a new study by researchers from the University of California, San Diego School of Medicine reveals the unsuspected plasticity of some of these gene expression programs. Their findings, to be published in the May 15 ...

Scientists from The Scripps Research Institute have identified a class of compounds that could be a boon to basic research and drug discovery. In a new study, published online in Nature Chemical Biology on May 15, 2011, the researchers show the new compounds powerfully and selectively block the activity of a large and diverse group of enzymes known as "serine hydrolases." Previously discovered serine hydrolase-blocking compounds have been turned into drugs to treat obesity, diabetes, and Alzheimer's disease, and are currently in testing as treatments for pain, anxiety, ...

Computer games are not just for kids. New research published in Journal of NeuroEngineering and Rehabilitation, a BioMed Central open access journal, shows that computer games can speed up and improve a patient's recovery from paralysis after a stroke. It is often difficult for stroke victims to recover hand and arm movement, and 80-90% of sufferers still have problems six months later. Scientists in America looked at a group of people who had impaired use of one arm after a stroke and found that computer simulations and cutting edge techniques, used by the film industry ...

Most mechanical resonators damp (slow down) in a well-understood linear manner, but ground-breaking work by Prof. Adrian Bachtold and his research group at the Catalan Institute of Nanotechnology has shown that resonators formed from nanoscale graphene and carbon nanotubes exhibit nonlinear damping, opening up exciting possibilities for super-sensitive detectors of force or mass. In an article to be published in Nature Nanotechnology (DOI - 10.1038/NNANO.2011.71), Prof. Bachtold and his co-researchers describe how they formed nano-scale resonators by suspending tiny graphene ...

WASHINGTON — Long-term survival rates for patients with advanced prostate cancer suggest they can be good candidates for surgery, Mayo Clinic researchers have found. Their study found a 20-year survival rate for 80 percent of patients diagnosed with cancer that has potentially spread beyond the prostate, known as cT3 prostate cancer, and treated with radical prostatectomy, or surgery to remove the prostate gland. Previously, patients found to have cT3 prostate cancer were offered radiation or hormone treatment, but not radical prostatectomy. The researchers presented ...

The human brain has yet to explain the origin of one its defining features – the deep fissures and convolutions that increase its surface area and allow for rational and abstract thoughts. An international collaboration of scientists from the Yale School of Medicine and Turkey may have discovered humanity's beneficiary – a tiny variation within a single gene that determines the formation of brain convolutions – they report online May 15 in the journal Nature Genetics. A genetic analysis of a Turkish patient whose brain lacks the characteristic convolutions in part ...

A North Carolina man received a greatly reduced sentence as a result of the strong defense work of criminal attorney Patrick Roberts at the Roberts Law Group PLLC. After officers discovered a kilogram of cocaine in the man's car during a traffic stop, the man was facing up to 175 to 219 months in prison or about 18 years. Instead, he was sentenced to only 35 to 42 months. While the Roberts Law Group PLLC client is serving about three years in prison, his co-defendants - the other man in the same car and the alleged leader of the conspiracy - are serving about seven years ...

Boston (May 16, 2011) – Most degenerative diseases begin with a gradual loss of specific cell types that progresses, eventually leading to symptoms. For example, in type I diabetes, hyperglycemia commonly develops when approximately 80 percent of the beta cells in the pancreas are lost; in Parkinson's disease, motor dysfunction typically begins when neurons in a certain portion of the brain are decreased by 70 to 80 percent. Finding ways to stop early cell destruction is vital, but methods to do so have proven challenging because of limitations of models for early stages ...

PHILADELPHIA - Despite recent concerns that medications for attention deficit hyperactivity disorder (ADHD) could increase the risk of cardiovascular events in children and adolescents, an observational study conducted by researchers at the University of Pennsylvania School of Medicine and HealthCore Inc. finds they are no more likely to die from a severe cardiovascular event than those who do not take the drugs. The findings, published online in the journal Pediatrics, provide the first analysis of such events in a large population of children and adolescents receiving ...

WINSTON-SALEM, N.C. – Monday, May 16, 2011 – A new discovery in mice by researchers at Wake Forest Baptist Medical Center may one day allow doctors to spare some patients with acute myeloid leukemia (AML) from toxic treatments, while also opening the door for new therapeutic research. AML, the most common form of acute leukemia seen in adults, is an aggressive form of cancer that primarily affects the elderly. Despite years of research, outcomes for most patients remain poor, particularly for one subset of patients with a specific mutation of the FLT3 receptor. At ...

Climbing is possibly one of the riskiest things an adult tarantula can do. Weighing in at anything up to 50gm, the dry attachment systems that keep daintier spiders firmly anchored are on the verge of failure in these colossal arachnids. 'The animals are very delicate. They wouldn't survive a fall from any height,' explains Claire Rind from the University of Newcastle, UK. In 2006, Stanislav Gorb and his colleagues published a paper in Nature suggesting that tarantulas may save themselves from falling by releasing silk threads from their feet. However, this was quickly ...

MAY 16, 2011 – Critical new research has found that lesbian, gay, bisexual, and transgender (LGBT) youth who experience high levels of school victimization in middle and high school report impaired health and mental health in young adulthood, including depression, suicide attempts that require medical care, sexually transmitted diseases (STDs) and risk for HIV. This is the first known study to examine the relationship between school victimization during adolescence – specifically related to sexual orientation and gender identity – with multiple dimensions of young adult ...
