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.

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.

Medical ’pay for performance’ programs help improve care but not always, study finds
A new UCLA study shows that patient-care performance ratings for 25 medical groups across California improved significantly following the launch of a statewide pay-for-performance program in 2004 — but not when incentives focused on doctors' productivity.

Largest mass extinction linked to 21st century lung cancer epidemic
Largest mass extinction linked to 21st century lung cancer epidemic
The geologic conditions that very nearly annihilated life 250 million years ago are still killing people today. Parts of Xuan Wei County in Yunnan Province in China have the world" s highest known death rates from lung cancer in non-smoking women. For thirty years the region, which uses locally mined coal for domestic cooking and heating, has been the focus of intense scientific research to establish a cause.

UCLA study shows brain’s ability to reorganize
Visually impaired people appear to be fearless, navigating busy sidewalks and crosswalks, safely finding their way using nothing more than a cane as a guide. The reason they can do this, researchers suggest, is that in at least some circumstances, blindness can heighten other senses, helping individuals adapt.

Immune system activated in schizophrenia
Researchers at the Swedish medical university Karolinska Institutet have discovered that patients with recent-onset schizophrenia have higher levels of inflammatory substances in their brains. Their findings offer hope of being able to treat schizophrenia with drugs that affect the immune system. The causes of schizophrenia are largely unknown, and this hinders the development of effective treatments.

NanoSystems Institute at UCLA to host global symposium on nanobiotechnology
Nanotechnology has shown great promise for applications in the areas of energy, information technology and the environment. In the health and medicine fields, however, its promise has progressed beyond possibility to become reality. Nanoscale research has led to techniques and devices with the potential to revolutionize health care, including imaging tools that detect cancers at the atomic level, nanomachines programmed to release drugs within specific cells, and biosensors that monitor changes from deep within body organs.

Paradoxical protein might prevent cancer
Paradoxical protein might prevent cancer
One difficulty with fighting cancer cells is that they are similar in many respects to the body's stem cells. By focusing on the differences, researchers at Karolinska Institutet have found a new way of tackling colon cancer. The study is presented in the prestigious journal Cell. Molecular signal pathways that stimulate the division of stem cells are generally the same as those active in tumour growth.

Treatment to open blocked kidney arteries shows no real benefit to patients
Treating patients who suffer from narrowing of the main blood vessel to the kidney by inserting a metal stent provides little or no worthwhile clinical benefit, and given the risk of serious complications it should be used less, according to an international trial led by the University of Birmingham.

Combination treatment needed to fight dementia
Combination therapies to tackle multiple changes in the brain may be needed to combat the growing problem of dementia in ageing societies, according to a study by the University of Sheffield. The findings, which were published this week in the open access journal PLoS Medicine, show that multiple abnormal (pathological) processes in the brain are often involved in cases of dementia, and that the drugs currently in development to treat individual brain pathologies may have a limited impact on the overall burden of dementia in the population.

Why can’t chimps speak Study links evolution of single gene to human capacity for language
Scientists suspect that part of the answer to the mystery lies in a gene called FOXP2. When mutated, FOXP2 can disrupt speech and language in humans. Now, a UCLA-Emory University study reveals major differences between how the human and chimp versions of FOXP2 work, perhaps explaining why language is unique to humans.

Rejected hormone therapy gave fewer cases of breast cancer
A reduction in recent years in the number of cases of breast cancer in women aged 50-59 years most probably depends on a decrease in the use of hormone replacement therapy to relieve problems associated with the menopause. A large Swedish study under the auspices of Karolinska Institutet confirms suspicions against the hormone therapy.

Scientists question memory theory
Press Release Links: The long-held theory that our brains use different mechanisms for forming long-term and short-term memories has been challenged by new research from UCL, published today in PNAS . Neuroscientists formed this theory based on observation of patients with amnesia, a condition that severely disrupts the ability to form long-lasting memories.

Genetic cause of inflammatory bowel disease
Links: UCL researchers were part of the team to discover that mutations in either of two related genes can cause a severe form of inflammatory bowel disease (IBD) in young children. Erik Glocker (UCL Infection & Immunity) said: 'This discovery is a milestone in research on inflammatory bowel disease, and will enable us to gain further insights into the physiology and immunity of the intestine.' Glocker found the first mutation in the protein IL10R2 identified in the study.

Statement by Gerald Levey
I believe the selection of A. Eugene Washington to serve as the next dean of the David Geffen School of Medicine and vice chancellor of health sciences at UCLA is an inspired choice and signals a strong commitment to the issues of greatest importance to academic medicine in the coming years. Dr. Washington's distinguished background in medical research, clinical care, public health, and health care disparities taken together means he will be perfectly situated to lead what is already a great institution's health sciences program to new and even greater accomplishment.

New Hope for Stroke Patients
A drug used to treat Parkinson's disease will be trialled as a treatment for stroke patients working to regain mobility and independence, in the first large scale study of its kind. A collaborative team of researchers will investigate the impact of combining the drug L-dopa with conventional physiotherapy and occupational therapy to increase stroke patients' ability to relearn fundamental activities such as walking.

Smoking in pregnancy linked to brain changes and teenage drug experimentation
Smoking in pregnancy linked to brain changes and teenage drug experimentation
PA 281/09 Children born to mothers who smoked during pregnancy are more likely to experiment with drugs in their teens, the findings of a new study suggest. Research carried out by The University of Nottingham and a number of Canadian Universities found that children exposed to cigarette smoke in the womb were more likely to experiment with drugs, such as alcohol, cigarettes and marijuana, during adolescence.
