DTC genetic tests require innovative approach to enter global market

Direct-to-consumer (DTC) genetic tests available from retailers and the Internet let people learn about their genomes without going to a doctor, but they raise the question of who is responsible for oversight and regulation of these tests. Critics worry about safety risks if consumers base important lifestyle or medical decisions on inaccurate or misunderstood test results.

Smoking leads to epigenetic changes associated with cancer development: Research

For the first time, UK scientists have reported direct evidence that taking up smoking results in epigenetic changes associated with the development of cancer.The results were reported at the 35th Congress of the European Society for Medical Oncology (ESMO) in Milan, Italy.

Researchers determine genetic structures of bacteria that cause Lyme disease

Researchers Dr. Steven E. Schutzer of UMDNJ-New Jersey Medical School and Dr. Claire M. Fraser-Liggett of the Institute for Genome Sciences, University of Maryland, and their collaborators have made a major achievement toward better understanding Lyme disease, by determining the complete genetic structures of 13 strains of the bacteria that cause the disease.

Researchers create experimental vaccine for Alzheimer's disease

Researchers at UT Southwestern Medical Center have created an experimental vaccine against beta-amyloid, the small protein that forms plaques in the brain and is believed to contribute to the development of Alzheimer's disease.

Scientists identify molecular mechanism of muscle stem cell differentiation

Under normal circumstances, adult stem cells reside in muscle tissue, where they can differentiate into a number of different cell types. After an injury (or even a tough workout), muscles are inflamed as cells and molecules flood the area to control damage and begin repairs. When called upon to replace muscle tissue damaged by injury or genetic disease, some muscle stem cells differentiate, becoming new muscle cells, while others make more stem cells. At Sanford-Burnham Medical Research Institute (Sanford-Burnham), a team of scientists led by Pier Lorenzo Puri, M.D., Ph.D., recently uncovered the molecular messengers that translate inflammatory signals into the genetic changes that tell muscle stem cells to differentiate.

Research may offer new therapy targets for drug-resistant breast tumors

Researchers at the University of Illinois at Chicago College of Medicine have found how gene expression that may contribute to drug resistance is ramped up in unusual types of breast tumors. Their findings may offer new therapy targets.

Discovery can lead to new approach for treating MS in early stages

A deficiency in one of the immune system's enzymes affects the severity of autoimmune diseases such as MS, and explains why the course of these diseases can vary so much. New findings give an insight into how this enzyme deficiency can be diagnosed, and could lead to new medicines, reveals a thesis from the Sahlgrenska Academy.

Researchers discover rhythmic changes in synapse numbers regulate sleep cycles

With the help of tiny, see-through fish, Stanford University School of Medicine researchers are homing in on what happens in the brain while you sleep. In a new study, they show how the circadian clock and sleep affect the scope of neuron-to-neuron connections in a particular region of the brain, and they identified a gene that appears to regulate the number of these connections, called synapses.

Researchers reveal neural responses associated with empathy for others' pain

Witnessing a person from our own group or an outsider suffer pain causes neural responses in two very different regions of the brain. And, the specific region activated reveals whether or not we will help the person in need. Researchers at the University of Zurich studied the brain responses of soccer fans and now have neurobiological evidence for why we are most willing to help members of our own group.

Correcting vitamin D deficiency before orthopedic surgery improves patient outcome: Study

Almost 50 percent of patients undergoing orthopedic surgery have vitamin D deficiency that should be corrected before surgery to improve patient outcomes, based on a study by researchers at Hospital for Special Surgery (HSS) in New York City. Vitamin D is essential for bone healing and muscle function and is critical for a patient's recovery. The study appears in the October issue of The Journal of Bone and Joint Surgery.

Mouse study may help develop new therapies for spinal cord injury

Researchers at Karolinska Institutet have shown how stem cells, together with other cells, repair damaged tissue in the mouse spinal cord. The results are of potential significance to the development of therapies for spinal cord injury.

Clinical study data on Natural S-equol supplement presented at NAMS Annual Meeting

Four clinical studies that add to the evidence about the use of a new nutritional supplement containing the whole soy germ-based ingredient Natural S-equol to improve health were presented at the North American Menopause Society (NAMS) Annual Meeting.

Study finds boosting mitochondria may delay onset of Parkinson's disease

In a study that sheds new light on the causes of Parkinson's disease, researchers report that brain cells in Parkinson's patients abandon their energy-producing machinery, the mitochondria. A shutdown in fuel can have devastating effects on brain cells, which consume roughly 20 percent of the body's energy despite making up only 2 percent of body weight.

Roche´s Cellavista System useful for automated mES colony imaging: Study

A recent study depicted the use of Roche´s Cellavista System to rapidly and effectively carry out a clonal analysis of embryonic stem colony self-renewal in an end-point assay. The Cellavista System proved to be useful for automated mES colony imaging, as well as characterization of colonies as differentiated and undifferentiated based on gating of morphological and intensity criteria. Little or no interference from the feeder cell layers was seen in the analysis of the images.
