Peptide vaccine fights off breast tumors with help of bacteria-mimicking agents

With the help of immune system-stimulating molecules that mimic bacterial components, researchers have used a type of cancer vaccine to both delay and prevent breast tumors in mice.

Molecular change in 1918 pandemic influenza virus stops transmission

Experts at the Centers for Disease Control and Prevention have shown that a molecular change in the 1918 pandemic influenza virus stops its transmission in ferrets that were in close proximity, shedding light on the properties that allowed the 1918 pandemic virus to spread so quickly.

Scientists test technique for identifying newly recognized DNA variations that may influence disease risk

Rather than focus on errors and alterations in DNA sequence, the new technique highlights variations in the number of copies of a particular gene.

Media coverage of autism differs dramatically

Sifting through the pages of newspapers, most people reading stories about autism would think scientists are primarily grappling with understanding how environmental factors, such as childhood vaccines, might contribute to the condition.

Salmonella survives better due to altered DNA

Since 1995 there has been a considerable increase in the number of infections with a specific type of Salmonella bacteria transmitted via food.

Stroke risk for sickle cell children with early complications

Children with sickle cell disease who experienced major complications such as pain and lung disease early in life are at no greater risk for stroke or death during later childhood, new research from UT Southwestern Medical Center shows.

Virtual human metabolic network for medical science

Bioengineering researchers at UC San Diego have painstakingly assembled a virtual human metabolic network that will give researchers a new way to hunt for better treatments for hundreds of human metabolic disorders, from diabetes to high levels of cholesterol in the blood.

Scientists tackle huntingtin protein

McMaster scientists are very close to defining small molecule drugs that should be able to redirect the huntingtin protein from accumulating in the wrong place within brain cells, which could potentially translate to a therapy for Huntington's Disease (HD).

Gene produces springy protein keeping nerve cells flexible

If you bend a knee or an elbow, the nerves in your limbs stretch but do not break. A University of Utah study suggests why: A gene produces a springy protein that keeps nerve cells flexible. When the gene was disabled in tiny nematode worms, their nerve cells literally broke.

New understanding of cholera pathogen

Researchers at Rensselaer Polytechnic Institute have discovered new details about how bacteria generate energy to live. In two recently published papers, the scientists add key specifics to the molecular mechanism behind the pathogen that causes cholera.

Sequenom and Lenetix to develop Rhesus D prenatal diagnostic

Sequenom, Inc. and Lenetix Medical Screening Laboratory, Inc., a provider of rapid genetic screening and diagnostic testing for clinicians worldwide, today announced that they have entered into a collaboration and license agreement to develop and commercialize a proprietary non-invasive prenatal Rhesus D (RhD) incompatibility test based on Sequenom patent rights and RT PCR methodology.

SH2B1 protein plays a key role in controlling body weight, response to insulin and leptin

A single protein in brain cells may act as a linchpin in the body's weight-regulating system, playing a key role in the flurry of signals that govern fat storage, sugar use, energy balance and weight, University of Michigan Medical School researchers report.

Small molecule targets weak mRNA

A new strategy for fighting cancer aims to make its genes get lost in translation, according to a report in the January 26, 2007, issue of the journal Cell.

Chromatin plasticity gets a 3.7 Million Euro boost

The European Commission has awarded 3.7 Million Euro under the European Union Framework 6 Programme over the next four years to a new Marie Curie Research Training Network, coordinated by Dr. Andreas Ladurner at the European Molecular Biology Laboratory (EMBL).

Childhood abuse could significantly increase the risk of psychosis in later life

Using data from a large American epidemiological mental health survey, based on a nationally representative sample of over 5000 people, Dr Mark Shevlin and Dr Gary Adamson found that social and environmental factors, such as childhood abuse, could significantly increase the risk of psychosis in later life.

New study finds endurance athletes with ventricular arrhythmias have dysfunctional right ventricles

Some high-level athletes who take part in endurance sports can develop a rare but life-threatening condition called ventricular arrhythmia (VA) in which the heart beats at an abnormal rate and rhythm.

H5N1 genetic mutation observed in Egypt

Viruses with a genetic mutation, linked in laboratory testing to moderately reduced susceptibility to oseltamivir, have been discovered in two persons previously reported with H5N1 infections in Egypt.

Simple diagnostic test detects genetic signs of lung cancer in sputum

DNA coughed up along with phlegm could point to lung cancer, say researchers at the University of Maryland School of Medicine who are developing an inexpensive and non-invasive gene probe to help diagnose early stage lung cancer in current and former smokers.

Lung neutrophils produce histamine in significant quantities

In a surprise finding, scientists have discovered that histamine, the inflammatory compound released during allergic reactions that causes runny nose, watery eyes, and wheezing, can be produced in large amounts in the lung by neutrophils, the white blood cells that are the major component of pus.
