Microevolutionary analysis of Clostridium difficile genomes to investigate transmission 2013-01-25

By BioMed Central Limited

Over recent years, hospital-acquired Clostridium difficile infections have been a significant problem in UK hospitals and globally. There have been concerns that infections may be due to transmission between symptomatic patients, either directly, or indir

Chromosome 'anchors' organize DNA during cell division: New role for telomeres in cellular growth may shed light on aging and age-related diseases 2013-01-25

By Salk Institute

For humans to grow and to replace and heal damaged tissues, the body's cells must continually reproduce, a process known as "cell division," by which one cell becomes two, two become four, and so on. A key question of biomedical research is how

Understanding the cellular patterns of development: Key mechanism in development involves 'paused' RNA polymerase 2013-01-25

By Stowers Institute for Medical Research

For a tiny embryo to grow into an entire fruit fly, mouse or human, the correct genes in each cell must turn on and off in precisely the right sequence. This intricate molecular dance produces the many parts of the whole creature, from muscles and skin to

Sync to grow: Oscillation of gene activity may underlie how embryos grow in proportion 2013-01-25

By European Molecular Biology Laboratory (EMBL)

Researchers are one step closer to understanding how embryos develop and grow while always keeping the same proportions between their various parts. Their findings, published today in Nature, reveal that scaling of the future vertebrae in a mouse embryo i

Chronic worriers at higher risk for PTSD, research finds 2013-01-25

By Michigan State University

People who worry constantly are at greater risk for post-traumatic stress disorder, according to new research.

New compound reverses fatty liver disease 2013-01-25

By Scripps Research Institute

Scientists have developed the first synthetic compound that can reverse the effects of a serious metabolic condition known as fatty liver disease.

Muscle weakness in Down syndrome: New study offers insights 2013-01-25

School shootings: What we know and what we can do 2013-01-25

By Springer

School shootings at elementary, secondary and higher education institutions have been a painful reality for American society. But can anything realistically be done to prevent these horrific crimes? A new article attempts to parse out what we have learned

Changes in progenitor cell population in breast may be overlooked factor in breast cancer 2013-01-25

By American Society for Cell Biology

DNA mutations that accumulate as women age are not the sole contributor to higher frequency of breast cancer in women over 50. In breast cancer and aging, changes in the populations of progenitor cells in breast tissue may be a powerful and until now over

New molecule linked to late-stage breast cancer 2013-01-25

By Case Western Reserve University

Researchers have identified a molecule linked to more aggressive forms of breast cancer -- a discovery that could point the way to potential cures.

Hybrid tunnel may help guide severed nerves back to health 2013-01-25

By Penn State

Building a tunnel made up of both hard and soft materials to guide the reconnection of severed nerve endings may be the first step toward helping patients who have suffered extensive nerve trauma regain feeling and movement, according to a biomedical engi

Perceived stress may predict future coronary heart disease risk 2013-01-25

By Columbia University Medical Center

Are you stressed? Results of a new meta-analysis of six studies involving nearly 120,000 people indicate that the answer to that question may help predict one’s risk of incident coronary heart disease (CHD) or death from CHD.

Alzheimer's disease: Cutting off immune response promises new approach to therapy 2013-01-25

By German Center for Neurodegenerative Diseases

Researchers have identified a protein as a potential target for the treatment of Alzheimer's disease. The molecular complex is part of the immune system and a driving force for inflammatory responses of the brain. Blocking its activity may pave the way fo

Rare, lethal childhood disease tracked to failure to degrade nerve cells' filaments 2013-01-25

By American Society for Cell Biology

A defective protein explains why a failure in protein degradation would lead to the massive aggregations of a class of filaments that disrupt the functioning of neurons of children with the rare, untreatable genetic disease giant axonal neuropathy. Discov

Rise in New Jersey autism prevalence documented in new study 2013-01-25

By University of Medicine and Dentistry of New Jersey (UMDNJ)

In a study of 58 communities in four New Jersey counties, autism spectrum disorder (ASD) prevalence is found to have risen from 10.6 per thousand in 2002, to 17.4 per thousand in 2006.

Regulator of healthy life span uncovered 2013-01-25

By Mayo Clinic

A new series of studies in mouse models uncovered that the aging process is characterized by high rates of whole-chromosome losses and gains in various organs, including heart, muscle, kidney and eye, and demonstrate that reducing these rates slows age-re

Radio waves to kidneys lower persistent high blood pressure 2013-01-25

By American Heart Association

A minimally invasive procedure lowered blood pressure in patients whose condition failed to respond to medication. Catheter-based renal denervation was found to be safe and effective in lowering blood pressure up to one year after starting treatment, and
