Gene patenting policies affect patient access to testing for disease-causing genes: Study

Policies allowing genes to be patented can make it more difficult for patients to access testing for important disease-causing gene mutations, according to a series of papers in a special online supplement published by Genetics in Medicine, the official peer-reviewed journal of The American College of Medical Genetics.

Ohio scientists demonstrate existence of effective technology for nationwide newborn screening of SMA

Scientists in Ohio studying Spinal Muscular Atrophy (SMA) have concluded that the technology now exists to carry out nationwide screening of newborn children and pregnant mothers. The study, published in the American Journal of Medical Genetics, reveals that effective screening may allow parents to find proactive treatments before the symptoms become irreversible.

Inadvertent reprogramming of genes in peripheral nervous system may cause chronic pain

Chronic pain severely limits patients' quality of life and is among the cost drivers in U.S. health care. Patients can suffer pain without an apparent cause and often fail to respond to available treatments. Mayo Clinic researchers and collaborators now report that chronic pain may be caused by the inadvertent reprogramming of more than 2,000 genes in the peripheral nervous system. The research findings appear in the current issue of the journal Genome Research.

SBMC 2010 to focus on systems-biological analysis of processes in mammalian cells

More targeted drug development thanks to systems biology - scientists at the SBMC 2010 in Freiburg explain how this works. Systems biology has finally come of age. Evidence for this is the third Conference on Systems Biology of Mammalian Cells (SBMC), which will take place on June 3-5, 2010 at the Concert Hall Freiburg (Konzerthaus) under the auspices of Prof. Dr. Annette Schavan, German Federal Minister of Education and Research.

Movements of satellite cells could help patients with muscular dystrophy: MU researchers

When muscle tissue experiences trauma or disease, such as muscular dystrophy, stem cells in the muscle known as "satellite cells" respond to repair and regenerate the muscle. These cells are particularly important in neuromuscular diseases, such as muscular dystrophy, which affect muscle stability and repair.

Majority of Americans fall short in consuming key phytonutrients

Americans who fall short in meeting their daily fruit and vegetable intakes based on government guidelines are also likely to fall short in common bone-building nutrients like calcium and vitamin D, according to a newly released report by the Nutrilite Health Institute called America's Phytonutrient Report: Bone Health by Color.

Study highlights benefits of using endometrial stem cells to restore functioning of brain cells

Stem cells derived from the endometrium (uterine lining) and transplanted into the brains of laboratory mice with Parkinson's disease appear to restore functioning of brain cells damaged by the disease, according to a new study by Yale School of Medicine researchers.

Neurons' complicated tree-like structure formation unravelled

A breakthrough about the formation and maintenance of tree-like nerve cell structures could have future applications in the treatment of neurodegenerative diseases and the repair of injuries in which neurons are damaged. The findings by the international team led by Prof. Benjamin Podbilewicz of the Technion-Israel Institute of Technology Faculty of Biology are published in the May 6th issue of Science Express.

NIST, UM researchers detail operation of liposome manufacturing technique

Pop a bubble while washing the dishes and you're likely to release a few drops of water trapped when the soapy sphere formed. A few years ago, researchers at the National Institute of Standards and Technology pioneered a method using a microscopic fluidic (microfluidic) device that exploits the same principle to create liquid-filled vesicles called liposomes from phospholipids, the fat complexes that are the building blocks for animal cell membranes

Advances in combination adult stem cell treatment for acute myocardial infarction presented at SCAI

This week, TCA Cellular Therapy's Medical Director Gabriel Lasala, M.D. presents advances in a proprietary combination adult stem cell treatment for acute myocardial infarction at the Society for Cardiovascular Angiography and Interventions (SCAI) scientific conference in San Diego.

Progestins increase chances of cancer metastasizing: Study

After menopause, 6 to 10 million women take hormone therapies, which are often a combination of estrogen and progestin, to replace hormones lost from inactive ovaries. Progestin is a hormone that is used to counteract the potentially negative effects of estrogen therapy on the uterus. In studies sponsored by the National Institutes of Health, evidence has been found that estrogen and progestin in hormone therapies increase the risk of breast cancer in post-menopausal women.

DNA sequence of amphibian genome sheds light on the study of embryonic development

A pair of University of Houston researchers contributed to the assembly of the first comprehensive DNA sequence of an amphibian genome, which will shed light on the study of embryonic development, with implications for preventing birth defects and more effectively treating many human diseases.

CDI, iPS Academia Japan announce licensing agreement for seminal iPSC patent portfolio

Cellular Dynamics International, Inc. (CDI), the world's largest producer of cellular tools for drug discovery and safety derived from induced pluripotent stem cells (iPSCs), and iPS Academia Japan, Inc., today announced a nonexclusive licensing agreement for the seminal iPSC patent portfolio arising out of the work of Dr. Shinya Yamanaka, M.D., Ph.D., Center for iPS Cell Research and Application (CiRA), Kyoto University.

Advances in genetic research could help develop personalized pain medications

In the not too distant future, it may be possible to discern an individual's genetic predisposition to chronic pain conditions and treat them proactively to prevent lifetime afflictions, according to research presented today at the American Pain Society's (www.ampainsoc.org) annual scientific meeting.

Neuroscientists show how individual neurons carry significant aspects of sensory processing

Pioneering a novel microscopy method, neuroscientist Arthur Konnerth and colleagues from the Technische Universitaet Muenchen (TUM) have shown that individual neurons carry out significant aspects of sensory processing: specifically, in this case, determining which direction an object in the field of view is moving.

THI at St. Luke's reveals new insights on how adult stem cells repair damaged hearts following heart attack

Physician scientists at the Texas Heart Institute at St. Luke's Episcopal Hospital (THI at St. Luke's) are publishing research this week that reveals new insights into how a particular set of human adult stem cells helps repair damaged hearts following a heart attack in laboratory mice.

Peptides: A new clue on the origins of life

Emory University scientists have discovered that simple peptides can organize into bi-layer membranes. The finding suggests a "missing link" between the pre-biotic Earth's chemical inventory and the organizational scaffolding essential to life.

The emerging science of epigenetics

Human embryonic stem cells (hESCs) possess remarkable properties of self-renewal and pluripotency, the ability to become almost any kind of cell within the body. And yet they share the same genome or set of genes with lineage-committed cells, cells fated to be or do one thing.
