Study demonstrates efficacy of genotyping technology in identifying source of clinic infection outbreak

Researchers from East Carolina University used a new technique of genotyping to identify the source of a hematology clinic outbreak of Mycobacterium mucogenicum, a gram-positive, acid-fast bacteria found in tap water. This is the first outbreak of M. mucogenicum in an ambulatory care setting; five other outbreaks have been reported in hospital settings since 1995.

Without B-Raf and C-Raf proteins mice's fur turns white

These proteins are required for melanocyte stem cell self-maintenance and, as such, correct pigmentation throughout the mice's life span. Without these two proteins, the mice's fur turns white. Their research is published in the review 'Cell Report' and paves the way for serious possibilities in terms of stopping the formation of melanomas, tumours that originate from melanocyte cells.

Skin's outmost layer is the first line of defense against UV radiation

Reinhold Dauskardt, PhD, of Stanford's Department of Materials Science and Engineering has been studying skin for years. But when he sent his students to look for data on the mechanical properties of skin, they came back empty-handed. A lot was known about skin structure and disease, but few papers actually talked about its mechanical function - its ability to stretch and resist tension without tearing.

BUSM leads genome-wide evaluation of genetic variants associated with Parkinson's disease

Boston University School of Medicine investigators have led the first genome-wide evaluation of genetic variants associated with Parkinson's disease (PD). The study, which is published online in PLOS ONE, points to the involvement of specific genes and alterations in their expression as influencing the risk for developing PD.

GW professor to develop blood test for early detection of breast cancer

Today, patients with precancerous lesions, or early-stage breast cancer are usually diagnosed after a mammography screening. This method of detection can lead to false-positives and overtreatment, since mammography cannot determine whether pre-cancerous cells will actually turn into breast cancer. This may all change after Sidney Fu, M.D., professor of medicine at the George Washington School of Medicine and Health Sciences (SMHS), completes his study of early breast cancer detection using novel small RNA (microRNA or miRNA) biomarkers.

Researchers determine function of new IKKα enzyme variant in colorectal cancer

Researchers from IMIM, Hospital del Mar Medical Research Institute, have succeeded in determining the function of a new variant of enzyme IKKalpha (IKKα) to activate some of the genes taking part in the tumor progressions of colorectal cancer.

Mouse genome consists of 10-nm chromatin fibres

Scientists in Canada and the United States have used three-dimensional imaging techniques to settle a long-standing debate about how DNA and structural proteins are packaged into chromatin fibres. The researchers, whose findings are published in EMBO reports, reveal that the mouse genome consists of 10-nm chromatin fibres but did not find evidence for the wider 30-nm fibres that were previously thought to be important components of the DNA architecture.

Researchers identify genetic risk allele for uterine fibroids

Uterine fibroids are the most common type of pelvic tumors in women and are the leading cause of hysterectomy in the United States. Researchers from Brigham and Women's Hospital (BWH) are the first to discover a genetic risk allele (an alternative form of a gene) for uterine fibroids in white women using an unbiased, genome-wide approach.

Newborn mice use mum's unique odour to begin breastfeeding

Researchers show for the first time that a mammal begins to suckle its mother's milk through a learned response built on learning her unique combination of smells. When it is born, the newborn is exposed to the smell of its mother's amniotic fluid and the baby then responds to those smells to feed.
