Discovery offers new treatment for epilepsy

2012-11-21
(Press-News.org) New drugs derived from components of a specific diet used by children with severe, drug-resistant epilepsy could offer a new treatment, according to research published today in the journal Neuropharmacology.

Scientists from Royal Holloway, in collaboration with University College London, have identified specific fatty acids that have potent antiepileptic effects, which could help control seizures in children and adults.

The discovery could lead to the replacement of the ketogenic diet, which is often prescribed for children with severe drug-resistant epilepsy. The high fat, low carbohydrate diet is thought to mimic aspects of starvation by forcing the body to burn fats rather than carbohydrates. Although often effective, the diet has attracted criticism, as side effects can be significant and potentially lead to constipation, hypoglycaemia, retarded growth and bone fractures.

By pinpointing fatty acids in the ketogenic diet that are effective in controlling epilepsy, researchers hope that they can develop a pill for children and adults that could provide similar epilepsy control, but lacks the side effects of the diet.

Professor Robin Williams from the Centre of Biomedical Sciences at Royal Holloway said: "This is an important breakthrough. The family of medium chain fatty acids that we have identified provide an exciting new field of research with the potential of identifying, stronger, and safer epilepsy treatments."

The study tested a range of fatty acids found in the ketogenic diet against an established epilepsy treatment. Researchers found that not only did some of the fatty acids outperform the drug in controlling seizures, they also had fewer side effects.

Professor Matthew Walker from the Institute of Neurology, University College London said: "Epilepsy affects over 50 million people worldwide and approximately a third of these people have epilepsy that is not adequately controlled by our present treatments. This discovery offers a whole new approach to the treatment of drug-resistant epilepsies in children and adults."

The research also builds on work funded by the NC3Rs in which most of the animal testing normally used in drug development for epilepsy has been replaced by using a simple amoeba to initially screen and identify improved treatments.

Professor Williams added: "Animals are often used in the search for new epilepsy treatments. Our work provides a new approach, helping us to reduce reliance on animals and provide potential major improvements in human health."

The specific fatty acids identified in this work are the subject of a patent application, and Royal Holloway is seeking commercial collaborators to pursue the potential for new drug development.

Researchers decode birch tree genome sequence for the first time

2012-11-21
Scientists from Queen Mary, University of London have sequenced the genetic code of a birch tree for the first time, which could help protect British birch populations. The genome, which is around 450 million letters, will help researchers understand the genetic basis of traits such as disease resistance and growth shape. There are over sixty species of birch trees around the world, with huge ecological and commercial importance. They are an essential part of the Boreal forest located around the North Pole, which is the world's largest land-based ecosystem. The team ...

Warming to shift heavy rainfall patterns in the UK

2012-11-21
It appears that it's not just us Brits who are fascinated with the UK weather. A group of researchers from Germany has taken to investigating the potential changes in extreme rainfall patterns across the UK as a result of future global warming and has found that in some regions, the time of year when we see the heaviest rainfall is set to shift. The study, published today, 21 November, in IOP Publishing's journal Environmental Research Letters, finds that between 2061 and 2100, the south-east of the country will likely experience its most extreme rainfall later in the ...

Low muscle strength in adolescence linked to increased risk of early death

2012-11-21
Research: Muscular strength in male adolescents and premature death: cohort study of one million participants Low muscle strength in adolescence is strongly associated with a greater risk of early death from several major causes, suggests a large study published on bmj.com today. The effect is similar to well established risk factors for early death like being overweight or having high blood pressure, leading the authors to call for young people, particularly those with very low strength, to engage in regular physical activity to boost their muscular fitness. High ...

Trial results 'do not support the use of general health checks' warn experts

Research: General health checks in adults for reducing morbidity and mortality from disease: Cochrane systematic review and meta-analysis Editorial: The value of conducting periodic health checks Researchers have found that routine general health checks, which have become common practice in some countries, do not reduce the number of deaths from cardiovascular disease or cancer. They do, however, increase the number of new diagnoses. Health checks were defined as screening for more than one disease or risk factor in more than one organ system offered to a general ...

High-speed video and artificial flowers shed light on mysteries of hummingbird-pollinated flowers

2012-11-21
How flowers have evolved particular colours, shapes and scents to attract pollinators has long fascinated ecologists. Now, using artificial flowers and high-speed video, researchers have gained intriguing insights into the intimate relationship between hummingbirds and the flowers they pollinate. The study, published in the British Ecological Society's journal Functional Ecology, is the first to measure how much energy hummingbirds use while hovering to feed from flowers of different orientation. Hummingbirds are among the smallest and most brightly-coloured birds on Earth, ...

Naerly 90 percent of clinical trialists think data should be more easily shared

2012-11-21
Research: Sharing of clinical trial data among trialists: a cross sectional survey Nearly nine out of ten clinicians carrying out biomedical research trials believe that trial data should be shared more easily, even though they do express some practical concerns, a study published today on bmj.com reveals. BMJ has long championed transparency in medical research. Last month, the journal launched an open data campaign to compel greater accountability in healthcare, and from January 2013, it will require a commitment from trialists to make their data available on reasonable ...

New test for tuberculosis could improve treatment, prevent deaths in Southern Africa

2012-11-21
Boston, MA — A new rapid test for tuberculosis (TB) could substantially and cost-effectively reduce TB deaths and improve treatment in southern Africa—a region where both HIV and tuberculosis are common—according to a new study by Harvard School of Public researchers. "This test is one of the most significant developments in TB control options in many years," said lead author Nicolas Menzies, a PhD candidate in health policy at Harvard School of Public Health. "Our study is the first to look at the long-term consequences of this test when incorporated into routine health ...

Research shows diabetes drug improves memory

2012-11-21
An FDA-approved drug initially used to treat insulin resistance in diabetics has shown promise as a way to improve cognitive performance in some people with Alzheimer's disease. Working with genetically engineered mice designed to serve as models for Alzheimer's, University of Texas Medical Branch at Galveston researchers found that treatment with the anti-insulin-resistance drug rosiglitazone enhanced learning and memory as well as normalized insulin resistance. The scientists believe that the drug produced the response by reducing the negative influence of Alzheimer's ...

UCSB anthropologist studies reciprocity among chimpanzees and bonobos

2012-11-21
(Santa Barbara, Calif.) –– When your neighbor asks to borrow a cup of sugar and you readily comply, is your positive response a function of the give and take that characterize your longstanding relationship? Or does it represent payment –– or prepayment –– for the cup of sugar you borrowed last week, or may need to borrow a month from now? Adrian Jaeggi, a postdoctoral researcher in anthropology at UC Santa Barbara, and a junior research fellow at the campus's SAGE Center for the Study of the Mind, is studying this question of reciprocity, using chimpanzees and bonobos ...
