UCLA scientists find molecular switch to prevent Huntington’s disease in mice
UCLA scientists have identified a molecular switch that prevents Huntington's disease from developing in mice. Published in the Dec. 24 edition of the journal Neuron, the discovery suggests a new approach to treating the genetic disorder, which ultimately leads to death in as little as 10 years. Affecting one out of every 10,000 Americans, Huntington's progressively deprives patients of their ability to walk, speak, think clearly and swallow.

Risk with obesity may be greater than previously thought
Risk with obesity may be greater than previously thought
The link between obesity and mortality from cardiovascular disease, diabetes and certain forms of cancer may be substantially underestimated, according to a new study from Karolinska Institutet. The study, which is published in the scientific journal BMJ, also suggests that some of the adverse consequences of being underweight may be overstated.

New human reproductive hormone could lead to novel contraceptives
BERKELEY — Nearly 10 years after the discovery that birds make a hormone that suppresses reproduction, University of California, Berkeley, neuroscientists have established that humans make it too, opening the door to the development of a new class of contraceptive and possible treatments for cancer or other diseases.

Marking of tissue-specific genes in embryonic stem cells crucial to ensure proper cell function
Tissue-specific genes, long thought to be dormant or unmarked for activation in embryonic stem cells, are indeed marked by transcription factors, and this marking may be crucial for the function of tissues derived from stem cells, UCLA Broad Stem Cell Center researchers have discovered. The findings, published in the Dec.

Gene variant connected with lung function and risk of COPD
A variant of the gene encoding the MMP12 protein is associated with increased lung function in children with asthma and in adult smokers. It is also associated with a decreased risk of chronic obstructive pulmonary disease (COPD) by 35 percent in adult smokers, according to an international study published in New England Journal of Medicine.

Predicting Insurgent Attacks with a Mathematical Model
December 17, 2009 — When bombs and bullets left 37 dead during Friday prayers at a mosque in Pakistan, earlier this month, the insurgency was using the element of surprise. Unpredictability is the hallmark of modern insurgent attacks such as this one. However, the likelihood of such events, their timing and strength can now be estimated and managed before occurring, according to a new study by researchers at the University of Miami.

Oldest case of leprosy found in 1st century tomb
Analysis of human remains buried in the 1st century 'Tomb of the Shroud? in Jerusalem has revealed evidence of ancient leprosy and tuberculosis. The new research, involving UCL researchers, is published in the journal PLoS One today. This is the first time that a 1st century tomb from Jerusalem has been investigated by molecular methods.

Informal social networks better at encouraging Hispanics to prepare for disasters, study finds
Historically, authorities have used broad media campaigns to encourage the public to prepare for disasters — an approach that has proven largely ineffective. For this new study, UCLA researchers sought to test novel, culturally tailored, informal social networking approaches to improve disaster preparedness, using data on 231 Hispanics in Los Angeles County.

Mastery of physical goals lessens disease-related depression
Physically active individuals have an increased sense of accomplishment, or situation-specific self-confidence, which in turn results in reduced depression and reduced fatigue, said Edward McAuley, a professor of kinesiology and community health at Illinois and lead author on the study.

Cancer diagnosis increases the risk of suicide and cardiovascular disease
Cancer diagnosis increases the risk of suicide and cardiovascular disease
Men who have recently been diagnosed with prostate cancer are at greater risk of committing suicide and developing and dying from cardiovascular disease, reveals a study from Karolinska Institutet published in the open scientific journal PLoS Medicine. "Cardiovascular disease and suicide can be viewed as a manifestation of exceptional psychological stress," says Katja Fall, one of the researchers behind the study.

New genes for lung disease discovered
PA321/09 Scientists have discovered five genetic variants that are associated with the health of the human lung. The research by an international consortium of 96 scientists from 63 centres in Europe and Australia sheds new light on the molecular basis of lung diseases. The new findings provide hope for better treatment for lung diseases like Chronic Obstructive Pulmonary Disease (COPD) and asthma.

Newly discovered mechanism by which blood clots form
Newly discovered mechanism by which blood clots form
Polyphosphate from blood platelets plays a key role in inflammation and the formation of blood clots, scientists from Karolinska Institutet have shown. The study, which is presented in the prestigious scientific journal Cell, describes how this mechanism can be used in treatment. Blood clots are a common cause of myocardial infarction and stroke, and they arise when blood coagulates and clogs a blood vessel.

Tamiflu proves no defence against swine flu virus
Treating suspected cases of swine flu with tamiflu in patients who are otherwise healthy provides no real benefit, according to researchers at the University of Birmingham. In research published on, Professor Nick Freemantle and Melanie Calvert found that oseltamivir, or tamiflu, the drug used to treat the H1N1 stain of the flu virus, does not necessarily prevent complications of the virus in otherwise healthy patients.

UCLA researchers demonstrate that stem cells can be engineered to kill HIV
Researchers from the UCLA AIDS Institute and colleagues have for the first time demonstrated that human blood stem cells can be engineered into cells that can target and kill HIV-infected cells ? a process that potentially could be used against a range of chronic viral diseases. The study, published Dec.

Scientists discover gene module underlying atherosclerosis development
By measuring the total gene activity in organs relevant for coronary artery disease (CAD), scientists at the Swedish medical university Karolinska Institutet have identified a module of genes that is important for the recruitment of white blood cells into the atherosclerotic plaque. The findings, which are to be published in the open-access journal PLoS Genetics, suggest that targeting the migration of white blood cells in the development of atherosclerosis may help to reduce the risk for adverse clinical effects such as ischemia and myocardial infarction.

Weight-loss proves effective cure for sleep apnoea
Weight-loss proves effective cure for sleep apnoea
For obese men, a dramatic weight loss can be an effective way to improve moderate to severe sleep apnoea, scientists at Karolinska Institutet report. Those with severe sleep apnoea when the study began benefited most from weight loss. "Our findings suggest that weight loss may be an effective treatment strategy for sleep apnoea in obese men," says Kari Johansson, one of the researchers involved in the study.

No connection between increased cell phone usage and change in brain tumor incidence
There was no substantial change in brain tumor incidence among adults 5 to 10 years after cell phone usage sharply increased, according to a new study conducted by researchers at Karolinska Institutet amongst others. The study was published in the latest issue of Journal of the National Cancer Institute.

Balancing protein intake, not cutting calories, may be key to long life
Getting the correct balance of proteins in our diet may be more important for healthy ageing than reducing calories, new research at UCL suggests. The new study may help explain why 'dietary restriction? (also known as calorie restriction) ' reducing food intake whilst maintaining sufficient quantities of vitamins, minerals and other nutrients ' appears to have health benefits.

UM Is Offering New Cognitive Behavioral Treatments for Anxiety and Depression at Low or No Cost
November 25, 2009 — Coral Gables — New research suggests that behavioral therapy can provide a safe, effective alternative treatment for anxiety and depression. These programs seem to work as well as-or better than-medication treatments. The University of Miami (UM) is now providing these evidence-based, quality treatments for anxiety and related disorders to the public, at low or no cost.
