Scientists uncover new layer of information in the genetic code

A hidden and never before recognized layer of information in the genetic code has been uncovered by a team of scientists at the University of California, San Francisco (UCSF) thanks to a technique developed at UCSF called ribosome profiling, which enables the measurement of gene activity inside living cells - including the speed with which proteins are made.

EU-funded project to help control appetite, combat obesity

The University of Liverpool is leading a £6milllion European project to develop and test new food products with satiating qualities to help control appetite, manage weight and combat obesity.

Potential new therapy that kills cancer cells selectively

Researchers have made a drug that helps the immune system to break down cancerous tumors. It has worked on breast, bowel, prostate, ovarian, brain, bladder and liver cancers, while previous studies show it can also be used to fight some blood cancers. If given early, the drug could even be a cure, researchers say.

Out-of-hospital use of GIK as therapy for ACS patients needs to be assessed

Patients experiencing symptoms such as chest pain who received from paramedics an intravenous solution consisting of glucose-insulin-potassium (GIK) had no reduction in the rate of progression to heart attack and no improvement in 30-day survival, although GIK was associated with a lower rate of the composite outcome of cardiac arrest or in-hospital death, according to a study appearing in JAMA.

Imatinib improves RFS, overall survival in GIST patients after surgery

Among patients with a high risk of recurrence of a gastrointestinal stromal tumor following surgery for its removal, patients who received imatinib (a drug to treat certain cancers) for 3 years instead of 1 had improved recurrence-free survival and overall survival, according to a study in the March 28 issue of JAMA.

Hyperinsulinemia itself not a cause of atherosclerosis

A number of studies have shown that excess insulin circulating in the bloodstream is a major independent risk factor for cardiovascular disease. However, a new study from Joslin Diabetes Center finds that this condition, called hyperinsulinemia, is itself not a cause of atherosclerosis.

Magnetic iron oxide nanoparticle-induced hyperthermia can kill cancer cells

Using nanoparticles and alternating magnetic fields, University of Georgia scientists have found that head and neck cancerous tumor cells in mice can be killed in half an hour without harming healthy cells.

Mount Sinai researchers present 86 abstracts and plenary sessions at ACC meeting

Mount Sinai School of Medicine researchers presented 86 abstracts and plenary sessions at the American College of Cardiology's (ACC) 61st Annual Scientific Session, including ground-breaking research on aggressive statin therapy, the prevalence of unrecognized cardiovascular disease symptoms in women, and morbidity associated with non-adherence to medication after stent implantation. The meeting took place March 23-27, 2012 in Chicago.

New microfluidic chip more effective in detecting flu outbreaks

The H1N1 flu pandemic in 2009 underscored weaknesses in methods widely used to diagnose the flu, from frequent false negatives to long wait times for results. Now Boston University researchers have developed a prototype of a rapid, low-cost, accurate, point-of-care device that promises to provide clinicians with an effective tool to quickly diagnose both seasonal and pandemic strains of influenza, and thus limit the spread of infection.

Experimental drugs from Sanofi and Regenron cut cholesterol in a new way

An experimental drug that acts in a novel way to lower cholesterol proved even more effective than statins and had few undesirable side effects, newly released data shows. The drug acts by modifying the way cholesterol levels are naturally controlled. A protein produced in the liver helps limit the amount of LDL, or “bad” cholesterol, that liver cells can remove from the bloodstream. The new drug, called REGN727, is a monoclonal antibody, made in a laboratory, that blocks the action of that protein.

Gold nanoparticles used to introduce chemical residues into the immune system

Developing a drug or vaccine requires a delicate balancing act with the immune system. On one hand, medications need to escape detection by the immune system in order to perform their function. But vaccinations - de-activated versions of a disease or virus - need to do the reverse. They prompt the immune system to create protective antibodies.

Simple placebo pill can track footprints of prior antidepressant use

Individuals with major depressive disorder (MDD) often undergo multiple courses of antidepressant treatment during their lives. This is because the disorder can recur despite treatment and because finding the right medication for a specific individual can take time.
