Inflammation in body fat is not only pernicious
It has been a common opinion that inflammation in adipose tissue may cause insulin resistance, and thereby type 2 diabetes. However, recent research from the Swedish medical university Karolinska Institutet, published in the New England Journal of Medicine, question the theory that inflammation in the body fat is only pernicious.

Researchers Focus on Psychological Care for Haiti's Earthquake Survivors
In the immediate aftermath of a natural disaster, addressing the physical needs of survivors—providing emergency medical care, food and water—can make the difference between life and death. But in the weeks, months and sometimes years that follow, the mental health effects may linger well after physical wounds have healed.

A sweet problem: Princeton researchers find that high-fructose corn syrup prompts considerably more weight gain
A sweet problem: Princeton researchers find that high-fructose corn syrup prompts considerably more weight gain
A Princeton University research team has demonstrated that all sweeteners are not equal when it comes to weight gain: Rats with access to high-fructose corn syrup gained significantly more weight than those with access to table sugar, even when their overall caloric intake was the same.  In addition to causing significant weight gain in lab animals, long-term consumption of high-fructose corn syrup also led to abnormal increases in body fat, especially in the abdomen, and a rise in circulating blood fats called triglycerides.

Sex on the brain: gene key to fruit fly gender
Sex on the brain: gene key to fruit fly gender
Researchers from Oxford University and the University of Glasgow have shown that a gene known as ' doublesex ' ( dsx ) plays a role in determining different brain circuitry in male and female fruit flies, resulting in gender-specific behaviours. The courtship behaviour of the fruit fly has long been used to study the relationship between genes and behaviour.

Caltech-led Team Provides Proof in Humans of RNA Interference Using Targeted Nanoparticles
Caltech-led Team Provides Proof in Humans of RNA Interference Using Targeted Nanoparticles
PASADENA, Calif.—A California Institute of Technology (Caltech)-led team of researchers and clinicians has published the first proof that a targeted nanoparticle—used as an experimental therapeutic and injected directly into a patient's bloodstream—can traffic into tumors, deliver double-stranded small interfering RNAs (siRNAs), and turn off an important cancer gene using a mechanism known as RNA interference (RNAi).

Radiotherapy can cause lasting vascular disease
For an as yet unknown reason, cancer radiotherapy can increase the risk of cardiovascular disease later in life, a problem that is growing as more and more people survive their cancer diagnosis. New research from Karolinska Institutet now suggests that sustained inflammation induced by post-radiotherapy changes in the gene expression in the arteries could be the cause.

Call for European Cystic Fibrosis healthcare gap to be closed
Call for European Cystic Fibrosis healthcare gap to be closed
A healthcare gap amounting to a ?death sentence? for Cystic Fibrosis (CF) children born in Eastern Europe must be closed say researchers from the EuroCareCF Coordination Action for Cystic Fibrosis. A new study led by the University of Dundee and published today in The Lancet, has found that CF patients in Eastern European countries die far younger than in other, wealthier, EU countries.

Colon cancer treatment for older patients often less aggressive than recommended, study finds
New results from a major initiative on the quality of cancer care in the United States show that patients with a common type of colon cancer, especially older patients, often do not receive the aggressive treatment with chemotherapy that research shows is associated with better survival. Led by researchers from UCLA and the RAND Corp., a nonprofit research organization, the study is among the first to track how findings from specialty research trials are applied in diverse practices in the community, where a wider variety of patients are treated.

Study Finds Bacteria Divide Like Clockwork
A team of researchers from UC San Diego and MIT has shown how cell division in a type of bacteria known as cyanobacteria is controlled by the same kind of circadian rhythms that govern human sleep patterns. The scientists? findings are detailed in paper in the March 19 issue of the journal Science. Previous studies have shown that even though cyanobacteria do not 'sleep' in the same way that humans do, they cycle through active and resting periods on a 24-hour schedule.

New statistical method for genetic studies could cut computation time from years to hours
In the ongoing quest to identify the genetic factors involved in disease, scientists have increasingly turned to genome-wide association studies, or GWAS, which enable the scanning of up to a million genetic markers in thousands of individuals. These studies generally compare the frequency of genetic variants between two groups — those with a particular disease and healthy individuals.

Researchers ID brain abnormalities in children exposed to methamphetamine in utero
It has long been known that alcohol exposure is toxic to the developing fetus and can result in lifelong brain, cognitive and behavioral problems. Now, a new report out of UCLA shows that the effects of prenatal methamphetamine exposure — or worse, a combination of methamphetamine and alcohol — may be even more damaging.

Milk drinking: in our genes?
Milk drinking: in our genes?
The ability to digest the milk sugar lactose ? also known as lactase persistence ? is a selectively advantageous and recent evolutionary genetic trait, which emerged about 7,500 years ago in Europe and probably later in other parts of the world. This means that, once weaned, people in most parts of the world (large parts of Africa, most of Asia, and Oceania) cannot digest milk for the rest of their life.

How muscle cells control fatty acid uptake
[Press Relese 2010-03-15] A new study from the Swedish medical university Karolinska Institutet shows that the blood vessels and muscles of the heart can regulate the uptake of fatty acids that we ingest through meat, milk products and other food. The researchers behind the study have also identified the way in which regulation is governed by the muscles themselves.
