Scientists use world’s fastest supercomputer to create the largest HIV evolutionary tree
Mapping Darwinian evolutionary relationships results in an HIV family tree that may lead researchers to new vaccine focus areas. Los Alamos, New Mexico, October 27, 2009 — Supporting Los Alamos National Laboratory's role in the international Center for HIV/AIDS Vaccine Immunology (CHAVI) consortium, researchers are using the Roadrunner supercomputer to analyze vast quantities of genetic sequences from HIV infected people in the hope of zeroing in on possible vaccine target areas.

One Shot of Gene Therapy and Children with Congenital Blindness Can Now See
PHILADELPHIA – Born with a retinal disease that made him legally blind, and would eventually leave him totally sightless, the nine-year-old boy used to sit in the back of the classroom, relying on the large print on an electronic screen and assisted by teacher aides. Now, after a single injection of genes that produce light-sensitive pigments in the back of his eye, he sits in front with classmates and participates in class without extra help.

Early treatment of fibromyalgia more effective
Early treatment of fibromyalgia more effective
People suffering from fibromyalgia have reduced activity in the parts of the brain that inhibit the experience of pain. Drugs that affect the CNS can be effective against the disease, and are thought to be even more so if administered early in its course. This according to a new thesis from Karolinska Institutet.

Feelings of stigmatization may discourage HIV patients from proper care, study finds
The feeling of stigmatization that people living with HIV often experience doesn't only exact a psychological toll — new UCLA research suggests it can also lead to quantifiably negative health outcomes.

Standards for a new genomic era
LANL among organizations proposing new genome sequence strategies Los Alamos, New Mexico, OCTOBER 21, 2009—A team of geneticists at Los Alamos National Laboratory, together with a consortium of international researchers, has recently proposed a set of standards designed to elucidate the quality of publicly available genetic sequencing information.

First-time Internet users find boost in brain function after just one week
You can teach an old dog new tricks, say UCLA scientists who found that middle-aged and older adults with little Internet experience were able to trigger key centers in the brain that control decision-making and complex reasoning after just one week of surfing the Web. The findings, presented Oct. 19 at the 2009 meeting of the Society for Neuroscience, suggest that Internet training can stimulate neural activation patterns and could potentially enhance brain function and cognition in older adults.

New discovery aids development of cancer treatments
The research, published online on 18 October 2009 in the journal Nature Chemistry has identified an imaging agent, which will enable scientists to understand the processes that occur within living cells and help develop new treatments for a range of diseases, including cancer. The imaging agent has helped to easily identify four-stranded DNA structures within the nucleus of cells, known as quadruplexes.

Health Care is Only Part of the Puzzle; Social Scientists Analyze Society’s Health and Success
Cambridge, Mass. October 16, 2009 - As health care moves to the forefront of the national discourse, new research in the social sciences argues that the health of the population and the success or failure of many public health initiatives hinges as much on cultural and social factors as it does on doctors, facilities, or drugs.

Skin cells may provide early warning for cancer risk elsewhere in body
BERKELEY — While some scientists have argued that cancer is such a complex genetic disease that you'd have to sequence a person's complete genome in order to predict his or her cancer risk, a University of California, Berkeley, cell biologist suggests that the risk may be more simply determined by inexpensively culturing a few skin cells.

Higher resource use at hospitals means reduced mortality among heart patients
Variations in how hospital resources are used across the United States have been a central component of the current discussion on health care reform. A new study by the University of California's five medical centers and Cedars-Sinai Medical Center in Los Angeles that examined variations in medical treatment, cost and patient outcomes between hospitals has some surprising new findings to add to the debate.

New findings on the formation of body pigment
New findings on the formation of body pigment
The skin's pigment cells can be formed from completely different cells than has hitherto been thought, a new study from the Swedish medical university Karolinska Institutet shows. The results, which are published in the journal Cell, also mean the discovery of a new kind of stem cell. The body's pigment gives essential protection against UV radiation.

Impaired foetal growth increases risk of asthma
A new study from Karolinska Institutet shows that children born with low birth weight are at a higher risk of developing asthma later in life. The study, which is published in the journal Pediatrics, is based on data on the incidence of asthma in 10,918 twins from the Swedish Twin Registry. Questionnaire data on asthma in 9- and 12- year old twins was linked to the national Swedish Medical Birth Registry which records, amongst other data, birth weight and gestational age (i.e.

Gene Team: Researchers Make Key Gene Discovery
October 08, 2009 — Miami — Researchers at the University of Miami Miller School of Medicine have identified a family of genes that may control the ability of the optic nerve to regenerate. The discovery of this gene family, as published in the October 9 issue of Science, is a big step forward for both visual science and neuroscience.

Mental disorders and increased risk of obesity: possible link
People with common mental disorders are at increased risk of becoming obese, according to new UCL research. Professor Mika Kivimäki of UCL Epidemiology & Public Health led research published today on the website of the British Medical Journal that shows that individuals with chronic or repeat episodes of common mental disorders, such as depression and anxiety, are particularly at risk of becoming obese.

Potential for drugs to treat age-related diseases
UCL scientists have extended the lifespan of mice by up to a fifth and cut the number of age-related diseases the animals suffer. The research which mimics the health benefits of reducing calorie intake and suggests that drug treatments for ageing and age-related diseases are feasible. In the 1930s scientists showed that reducing the calorie intake of laboratory rats while maintaining sufficient vitamins, minerals and other important nutrients in the animals can have health benefits.

Survey to Discover What Life with Coeliac Disease is Really Like
A large-scale survey to find out what it is really like living with coeliac disease will be launched by researchers at the University of Birmingham. Coeliac disease is an autoimmune disease in which the body's immune system attacks its own tissues in response to the presence of gluten, found in wheat, barley & rye.

Study IDs chemicals that could lead to new drugs for genetic disorders, cancer
Published in the Sept. 28 edition of the Journal of Experimental Medicine , the findings could lead to new medications for genetic diseases, such as cancer and muscular dystrophy, that are sparked by missing proteins. "When DNA changes, such as nonsense mutations, occur in the middle rather than the end of a protein-producing signal, they act like a stop sign that tells the cell to prematurely interrupt protein synthesis," said Dr. Richard Gatti, professor of pathology and laboratory medicine and of human genetics at the David Geffen School of Medicine at UCLA.

Flu triggers heart attacks but vaccination may offer protection
Flu can trigger heart attacks and cause cardiovascular death, but the influenza vaccine may offer protection for cardiac patients, according to a review by scientists from the UCL Centre for Infectious Disease Epidemiology published in the October edition of The Lancet Infectious Diseases . The cardiac complications of influenza infection are well known.

UCLA scientists make paralyzed rats walk again after spinal cord injury
UCLA researchers have discovered that a combination of drugs, electrical stimulation and regular exercise can enable paralyzed rats to walk and even run while supporting their full weight on a treadmill. Published Sept. 20 in the online edition of the journal Nature Neuroscience, the findings suggest that the regeneration of severed nerve fibers is not required for paraplegic rats to learn to walk again.
