Animal experiments show old antidepressant may reverse heart failure

A team of Johns Hopkins and other researchers have found in animal experiments that an antidepressant developed over 40 years ago can blunt and even reverse the muscle enlargement and weakened pumping function associated with heart failure.

New research may yield more effective treatment for childhood leukemia

A team of Israeli scientists at the Sheba Medical Center's Research Center for Leukemia and Childhood Malignancies has discovered a method for developing a more effective and less perilous treatment for those suffering from childhood leukemia, the most common cancer in children.

Quercetin may prevent hepatitis C infection; findings may lead to less toxic treatments

Researchers have identified two cellular proteins that are important factors in hepatitis C virus infection, a finding that may result in the approval of new and less toxic treatments for the disease, which can lead to liver cancer and cirrhosis.

Findings reveals 'limpet-like' proteins can play a key role in DNA repair

UK scientists have found that a crafty family of 'limpet-like' proteins can play a crucial role in repairing DNA damage - according to two research papers published in Nature today (Wednesday). These findings could pave the way to the design of new anti-cancer drugs which target this process.

Study to understand acoustic communication across animal species

Scientists who compare insect chirps with ape calls may look like they are mixing aphids and orangutans, but researchers have found common denominators in the calls of hundreds of species of insects, birds, fish, frogs, lizards and mammals that can be predicted with simple mathematical models.

Study reveals hereditary factors contribute to abdominal aortic aneurysm in twins

A new study in the January issue of the Journal of Vascular Surgery(®), published by the Society for Vascular Surgery®, reveals robust epidemiological evidence that hereditary factors contribute to aneurysm formation in twins.

Perturbing DISC1 gene could help researchers treat mental illness, says study

Scientists have long eyed mutations in a gene known as DISC1 as a possible contributor to schizophrenia and mood disorders, including depression and bipolar disorder. Now, new research led by Johns Hopkins researchers suggests that perturbing this gene during prenatal periods, postnatal periods or both may have different effects in mice, leading to separate types of brain alterations and behaviors with resemblance to schizophrenia or mood disorders.

Study reveals molecular mechanism that could lead to new approach in treating obesity

Mayo researchers collaborating with investigators at the University of Iowa, University of Connecticut and New York University (NYU) have discovered a molecular mechanism that controls energy expenditure in muscles and helps determine body weight. Researchers say this could lead to a new medical approach in treating obesity.

Genetic rogue elements could help diagnose breast and bowel cancer

Scientists at The University of Nottingham have found that a group of genetic rogue elements, produced by DNA sequences commonly known as 'junk DNA', could help diagnose breast and bowel cancer.

Swedish study opens new potential for combating resistant bacteria

Neisseria meningitidis, the meningococcus, is a bacterium that can cause diseases with high fatality rates, and there has therefore been considerable concern that, like other bacteria, it might become resistant to antibiotics. But now a study from örebro University and örebro University Hospital in Sweden shows that there has not been any increase in resistant meningococci in Sweden over the last 15 years. According to researcher Sara Thulin Hedberg, the reason for this may be that it is not especially advantageous for bacteria to develop resistance.

Annelie Wendeberg presents protocol for identification of environmental microbes

Metagenomics, the study of DNA isolated from samples of naturally occurring microbial populations, is rapidly growing. Improvements to cloning and sequencing techniques are allowing researchers to study microorganisms in environmental samples, and new knowledge of species interactions and community dynamics is emerging.

Vitamin C reverses accelerated aging due to Werner's syndrome

A new research discovery published in the January 2010 print issue of the FASEB Journal suggests that treatments for disorders that cause accelerated aging, particularly Werner's syndrome, might come straight from the family medicine chest. In the research report, a team of Canadian scientists show that vitamin C stops and even reverses accelerated aging in a mouse model of Werner's syndrome, but the discovery may also be applicable to other progeroid syndromes.
