Unlikely genetic suspect implicated in Dandy-Walker malformation

A genetic search that wound its way from patients to mouse models and back to patients has uncovered an unlikely gene critically involved in a common birth defect which causes mental retardation, motor delays and sometimes autism, providing a new mechanism and potentially improving treatment for the disorder.

Understanding emotional reactions for negative services

Service quality beliefs are usually positively related to customer satisfaction - the higher the perceived service quality, the higher the customer's satisfaction. However, an article published in the August issue of the Journal of Service Research finds this relationship may be more complicated in "negative service environments" (i.e., services that consumers would prefer not to have to use), such as health screening, diagnostic tests, or even auto repair.

Female supervisors more likely to be sexually harassed at work

Women who hold supervisory positions are more likely to be sexually harassed at work, according to the first-ever, large-scale longitudinal study to examine workplace power, gender and sexual harassment.

Scientists discover link between mutations in INPP5E gene and ciliopathies

An international team of scientists, led by researchers at the University of California, San Diego School of Medicine, have discovered a connection between mutations in the INPP5E gene and ciliopathies. Their findings, which may lead to new therapies for these diseases, will appear in the online edition of Nature Genetics on August 9.

Socioeconomic status plays no role in brain's continued ability to function with age

New UCLA research suggests that for seniors age 70 and older, socioeconomic status does not play a major role in the brain's continued ability to function. However, seniors who have never been married and widowers seem to perform more poorly as they age.

Novel approach for developing an AIDS vaccine

Researchers at the Yerkes National Primate Research Center, Emory University, believe conventional vaccine strategies should not be the only avenue explored in the development of an effective AIDS vaccine.

Only two stem cell lines account for most human embryonic stem cell research

For the past eight years, scientists who wanted to use federal funds for research on human embryonic stem cells had to restrict their studies to 21 cell lines approved by the National Institutes of Health. But an analysis by a researcher at the Stanford University School of Medicine suggests that only two of those lines have been used routinely.

Immune system protects cancer cells in first few days

During the very first few days of development of a cancer, our immune system recognizes cancer cells not as abnormal cells requiring eradication but as cells of the body that need to be protected. This result was obtained by the team led by David Klatzmann at the Laboratoire Immunologie (UPMC / CNRS / INSERM).

Two significant advances in treating lung cancer

Dr. Glen Weiss of the Translational Genomics Research Institute (TGen) and Scottsdale Healthcare this week announced two significant advances in treating lung cancer at an international cancer research conference.

More insulin-producing cells from a single transcription factor switch

Researchers have found a way in mice to convert another type of pancreas cell into the critical insulin-producing beta cells that are lost in those with type I diabetes. The secret ingredient is a single transcription factor, according to the report in the August 7th issue of Cell, a Cell Press journal.

Economic downturn will worsen obesity epidemic

Levels of debt have been associated with an increased risk of being fat. Researchers writing in the open access journal BMC Public Health blame the trend on the high price of healthy food, and a tendency for people worried by debt to comfort eat.

Changes in mtDNA can cause premature ageing

The normal ageing process has long been linked to problems with cell respiration, the process through which the cells extract energy from nutrients. Researchers at the Swedish medical university Karolinska Institutet have now shown how certain proteins that are synthesised in the cellular mitochondria - popularly known as the cells' power plants - become unstable and disintegrate, which in turn can impair cell respiration and cause premature ageing.

Scientists find key to strengthening immune response to chronic infection

A team of researchers from The Wistar Institute has identified a protein that could serve as a target for reprogramming immune system cells exhausted by exposure to chronic viral infection into more effective "soldiers" against certain viruses like HIV, hepatitis C, and hepatitis B, as well as some cancers, such as melanoma.

Proteomics helps find key to keeping cells in shape

Yale University researchers have discovered how a protein within most cell membranes helps maintain normal cell size, a breakthrough in basic biology that has implications for a variety of diseases such as sickle cell anemia and disorders of the nervous system.

Senators Harkin, Kennedy and Specter honored as champions of health research

The Foundation for the National Institutes of Health, Research!America and the Albert and Mary Lasker Foundation recognized these three senators for their continued support of research for health, their leadership and shared commitment to making it a high national priority, on Tuesday evening August 4th at the Russell Senate Office Building.

Discovery of possible mechanisms to protect against genetic alterations, diseases

Peering into the DNA of tiny yeast, researchers at the Moores Cancer Center at the University of California, San Diego and the San Diego Branch of the Ludwig Institute for Cancer Research have pinpointed a large number of genes that can prevent a type of genetic rearrangement that may lead to cancer and other diseases.

Discovery of a new Alzheimer's gene

A UC Irvine study has found that a gene called TOMM40 appears twice as often in people with Alzheimer's disease than in those without it. Alzheimer's, for which there is no cure, is the leading cause of elderly dementia.

Discovery of common trigger in cancer and normal stem cell reproduction

Researchers at Stanford University School of Medicine have discovered, for the first time, a common molecular pathway that is used by both normal stem cells and cancer stem cells when they reproduce themselves.

GE Global Research Biosciences technology celebrated fifth anniversary

From creating a new business in digital pathology to developing next generation diagnostic imaging agents and life sciences tools that are breaking new ground in the detection and treatment of disease, the Biosciences technology organization at GE Global Research today celebrated its fifth anniversary.

Genetic profiling of tumors could have 'immediate impact' on treating cancer

New work by MIT cancer biologists shows that the interplay between two key genes that are often defective in tumors determines how cancer cells respond to chemotherapy.
