Presence of gum disease may help dentists and physicians identify risk of cardiovascular disease

Individuals reporting a history of periodontal disease were more likely to have increased levels of inflammation, a risk factor for heart disease, compared to those who reported no history of periodontal disease, according to an American Journal of Cardiology report available online today.

$2.7 million boosts effort to create the big view of cancer

Many scientists like to discuss how each form of cancer is a distinct disease with its own causes and its own treatments. But researcher Hartmut "Hucky" Land, Ph.D., takes the opposite approach: He is hunting for the most basic rules that all cancers share to make good cells go bad.

Foxm1 gene mutation may cause immature lungs in newborns

Scientists have identified a gene critical to lung maturation in newborns and the production of surfactant, which lines lung tissues and prevents the lungs from collapsing.

Discovery of novel approach to suppress prostate cancer progression

Researchers at the University of Southern California (USC) have found that inactivating a specific biomarker for aggressive prostate cancer blocks the development of prostate cancer in animal models.

Discovery of new species of bacterium that causes leprosy

A new species of bacterium that causes leprosy has been identified through intensive genetic analysis of a pair of lethal infections, a research team reports in the December issue of the American Journal of Clinical Pathology.

Prion switching in response to environmental stress

If you have had a hard day at work, you may change your eating habits, perhaps favoring comfort food, but you don't suddenly develop the ability to eat the plate and cutlery.

Evidence of retina self-repair in mammals

Researchers at the University of Washington (UW) have reported for the first time that mammals can be stimulated to regrow inner nerve cells in their damaged retinas.

Seychelles flies could reveal evolutionary step to live birth

A species of fruit fly from the Seychelles Islands often lays larvae instead of eggs, UC San Diego biologists have discovered.

Sexual reproduction and evolution

The utility of sex, according to an intriguing new theory of evolutionary biology, may be its ability to promote genes that play well with many other partners rather than those that shine with just one specific set of genes.

Neurons in adult brain can remodel their connections

In work reported in the Nov. 24 online edition of the Proceedings of the National Academy of Sciences (PNAS) , Elly Nedivi, associate professor of neurobiology at the Picower Institute for Learning and Memory, and colleagues found that a type of neuron implicated in autism spectrum disorders remodels itself in a strip of brain tissue only as thick as four sheets of tissue paper at the upper border of cortical layer 2.

Major discovery in the control of bad cholesterol

A study performed by the team of Dr. Nabil G. Seidah, Director of the Biochemical Neuroendocrinology Research Unit at the IRCM, shows for the very first time that the degradation by PCSK9 of the LDLR receptor, which is responsible for removing the bad cholesterol (LDL-cholesterol) from the bloodstream, may be inhibited by a third protein, annexin A2.

Scientists identify blood component that turns anthrax bacteria virulent

Scientists from the Scripps Research Institute have discovered the key chemical that signals Bacillus anthracis , the bacterium that causes anthrax, to become lethal.

Researchers discover mechanism vital to the development of the hippocampus

Astrophysicists peer into the far corners of deep space for dark matter, but for neuroscientists at the Queensland Brain Institute (QBI) exploring the unknown is much closer to home.

Mechanisms of cardiovascular disease and cancer give clues to new therapies

Cardiovascular conditions leading to heart attacks and strokes are treated quite separately from common cancers of the prostate, breast or lung, but now turn out to involve some of the same critical mechanisms at the molecular level.

Does hormone treatment predispose patients to breast cancer?

Breast cancer, the leading cause of death among women in France, is the most commonly occurring cancer in women.

Bipolar disorder genes, pathways identified

Neuroscientists at the Indiana University School of Medicine have created the first comprehensive map of genes likely to be involved in bipolar disorder, according to research published online Nov. 21 in the American Journal of Medical Genetics.

Non-pharmacologic interventions for the control of osteoporosis and obesity

The Department of Biomedical Engineering at Stony Brook University received a $1.8 million grant from the National Institutes of Health (NIH) to investigate the biologic and physical mechanisms of very low-magnitude mechanical signals and how they strengthen bone and muscle.
