Mice with disabled gene that helps turn carbs into fat stay lean despite feasting on high-carb diet
BERKELEY — Researchers at the University of California, Berkeley, have identified a gene that plays a critical regulatory role in the process of converting dietary carbohydrates to fat. In a new study, they disabled this gene in mice, which consequently had lower levels of body fat than their normal counterparts, despite being fed the equivalent of an all-you-can-eat pasta buffet.

Moderate obesity takes years off life expectancy
A new analysis of almost one million people from around the world has shown that obesity can trim years off life expectancy. The Oxford University research found that moderate obesity, which is now common, reduces life expectancy by about 3 years, and that severe obesity, which is still uncommon, can shorten a person's life by 10 years.

Dormant Virus Causes Cancer
University of Birmingham scientists have revealed how a dormant virus triggers a type of cancer found in young people, according to research published in PLoS Pathogens* today (Friday). Burkitt's lymphoma** - a type of non-Hodgkin lymphoma - affects around 200 young adults aged between 13 and 24 each year in the UK and is more common in children living in equatorial Africa.

Research uncovers target for safe and effective drugs to prevent heart attack-causing blood clots
Researchers at the University of Birmingham have hit on a promising new molecule as a target for the development of better medicines to prevent blood clots, which could reduce lives lost from heart attacks and strokes. Yotis Senis - British Heart Foundation (BHF) Intermediate Research Fellow - and colleagues have discovered a vital new component of the trigger for blood clot formation, involving a protein called CD148.

Long-term ozone exposure linked to higher risk of death, finds nationwide study
BERKELEY — Long-term exposure to ground-level ozone, a major component of smog, is associated with an increased risk of death from respiratory ailments, according to a new nationwide study led by a researcher at the University of California, Berkeley. The study, to be published in the March 12 issue of the New England Journal of Medicine, analyzed the risk of death for both ozone and fine particulate matter, two of the most prevalent components of air pollution.

Ovarian cancer: UCL screening tests show promising results for early detection
Preliminary results of a UCL-led investigation suggest that testing women for ovarian cancers may become a reality. Following the largest randomised trial of ovarian cancer screening to date, Professor Ian Jacobs (Dean of UCL Health Sciences Research and Director of the UCL Institute for Women's Health), and Usha Menon (Head of the UCL Gynaecological Cancer Research Centre), have published their findings online in The Lancet Oncology today.

Stem cells replace stroke damaged tissue in rats
Stem cells replace stroke damaged tissue in rats
PA 59/09 Effective stem cell treatment for strokes has taken a significant step forward as scientists reveal how they have replaced stroke-damaged brain tissue in rats. Researchers at The University of Nottingham are among a team of scientists who have shown that by inserting tiny scaffolding with stem cells attached, it is possible to fill a hole left by stroke damage with brand new brain tissue within seven days.

Asthma breakthrough for scientists
Asthma breakthrough for scientists
PA 52/09 Scientists at The University of Nottingham have made a breakthrough in identifying gene variations that appear to increase a person's risk of asthma. The findings of the research could lead to better diagnosis and treatment of asthma which affects more than five million people in the UK. The scientists, led by Professor Ian Hall at University Hospital Nottingham, have discovered three specific gene variations that are indicators for an increased susceptibility to asthma.

Genetic finding provides new insight into female infertility
A research collaboration co-funded by the Wellcome Trust has identified a new genetic cause for primary ovarian insufficiency, a condition which can lead to infertility in women - a finding which could lead to the development of a possible diagnostic test. Primary ovarian insufficiency, also known as premature ovarian failure, is characterised by the loss of normal function of the ovaries before the age of 40 years.

Newly discovered gene plays vital role in cancer
Gene p53 protects against cancer and is usually described as the most important gene in cancer research. However, scientists at Karolinska Institutet have now shown that a previously unknown gene, Wrap53, controls the activity of p53. As the regulation mechanism is relatively unexplored, the study opens up new routes to solving the mystery of cancer.

Teenage obesity just as risky as being a smoker
Obese adolescents have the same risk of premature death in adulthood as people who smoke more than 10 cigarettes a day, according to a new study from Karolinska Institutet. What most interests the researchers is that the combination of overweight and smoking did not act synergistically as mortality risk factors.

Steroids ineffective in young children with wheeze
Steroids ineffective in young children with wheeze
PA49/09 New research involving medical experts at The University of Nottingham has found that steroid tablets do not reduce the symptoms of virus-induced wheezing in pre-school children. Researchers from the universities of Nottingham, Leicester and Bart's in London have been at the centre of a leading study to find out whether steroid medicine will relieve wheezing symptoms in children under five years of age.

Postnatal psychosis more common in older first-time mothers
Women who give birth for the first time after the age of 35 run a greater risk than younger first-time mothers of suffering a psychosis in the months after delivery. This according to a study from Karolinska Institutet published in the latest issue of the open access scientific periodical PLoS Medicine.

Link between vitamin D and genes in multiple sclerosis
Researchers have found evidence that a direct interaction between vitamin D and a common genetic variant alters the risk of developing multiple sclerosis (MS). The Oxford University-led research, published in PLoS Genetics, suggests that vitamin D deficiency during pregnancy and the early years may increase the risk of offspring developing MS later in life.

Cognitive training can alter the biochemistry of the brain
Researchers at the Swedish medical university Karolinska Institutet have shown for the first time that the active training of the working memory brings about visible changes in the number of dopamine receptors in the human brain. The study was conducted with the help of PET scanning and provides deeper insight into the complex interplay between cognition and the brain's biological structure.
