FDA seeks ban on Regenerative Sciences for violating cGMP

The U.S. Food and Drug Administration is seeking an injunction in federal court against Regenerative Sciences LLC, of Broomfield, Colo., citing violations of current good manufacturing practice (cGMP) that cause its cultured cell product to be adulterated. The product is also misbranded due to the lack of adequate directions for use and the failure to bear the "Rx only" symbol.

Attractiveness detrimental for women applying for masculine sex-typed jobs

While many see no downside to being beautiful, a professor at the University of Colorado Denver Business School says attractive women face discrimination when it comes to landing certain kinds of jobs.

UCSF researchers discover new technology purifying special types of stem cells

UCSF researchers are reporting the first success in very rapidly purifying one type of embryonic stem cell from a mix of many different types of embryonic stem cells in the culture dish. The technique, which avoids the need to genetically alter the cells to distinguish them, is a key advance, the researchers say, for obtaining the appropriate cells for repairing specific damaged tissues.

Drugs that reduce activity of ABDH6 enzyme can prevent brain damage: Study

A newly discovered molecular mechanism helps control the amount and effectiveness of a substance that mimics an active ingredient in marijuana, but that is produced by the body's own nerve cells.

Scientists identify role of PNPASE in regulating RNA import into mitochondria

Researchers at UCLA's Jonsson Comprehensive Cancer Center and the departments of Chemistry and Biochemistry and Pathology and Laboratory Medicine have uncovered a role for an essential cell protein in shuttling RNA into the mitochondria, the energy-producing "power plant" of the cell. The import of nucleus-encoded small RNAs into mitochondria is essential for the replication, transcription and translation of the mitochondrial genome, but the mechanisms that deliver RNA into mitochondria remain poorly understood.

UC Riverside scientists secure grants for tobacco control research

Tobacco-related disease kills more people worldwide than any other single factor. To help address this problem, the University of California, Riverside has received six grants from the University of California Tobacco-Related Disease Research Program (TRDRP), the most TRDRP grants the campus has received in any year.

Salamander research findings bring scientists closer to future regenerative therapies

Tissue regeneration in salamanders and newts seems like it should be the stuff of science fiction. But it happens routinely. Why can't we mammals just re-grow a limb or churn out a few new heart muscle cells as needed? New research suggests there might be a very good reason: Restricting our cells' ability to pop in and out of the cell cycle at will - a prerequisite for the cell division necessary to make new tissue - reduces the chances that they'll run amok and form potentially deadly cancers.

Scientists combine basic adipose tissue mass knowledge with clinical experience

These proceedings cover the nervous regulation of both white and brown adipose tissue mass. Different physiological parameters such as metabolism (lipolysis and thermogenesis) and secretory activity (leptin and other adipokines) are reviewed. The plasticity of adipose tissue (proliferation, differentiation and apoptosis) showing the presence of a neural feedback loop between adipose tissue and the brain, which plays a major role in the regulation of energy homeostasis, is discussed.

Researchers reprogram human embryonic stem cells to iPS cells for use in regenerative medicine

Human embryonic stem (ES) cells and adult cells reprogrammed to an embryonic stem cell-like state-so-called induced pluripotent stem or iPS cells-exhibit very few differences in their gene expression signatures and are nearly indistinguishable in their chromatin state, according to Whitehead Institute researchers.The pluripotency of ES cells fueled excitement over their use in regenerative medicine. While ethical hurdles associated with the clinical application of human ES cells appeared to have been overcome with the development of methods to create iPS cells, some recent research has suggested that ES and iPS cells have substantial differences in which sets of genes they express.

Survey reveals need for nutrition education among African Americans for disease prevention, management

Researchers looking for differences in eating habits of African Americans based on whether or not they had Type 2 diabetes uncovered an unexpected result: No matter what the blood sugar level was, the dietary intakes were pretty much the same.African Americans are 1.8 times more likely to develop Type 2 diabetes and 1.4 times more likely to be obese than are non-Hispanic whites, according to federal health agencies. Obesity is a leading risk factor for development of diabetes, a condition that results when the body cannot properly use insulin to transfer sugar from the blood to muscle and fat cells that use glucose for energy.

Alnylam publishes research findings of Sort1 gene role in cardiovascular disease development

Alnylam Pharmaceuticals, Inc. a leading RNAi therapeutics company, announced today the publication of new research findings in the journal Nature describing the discovery and validation of the role of the gene Sort1 in the development of cardiovascular disease, including myocardial infarction (MI). This work was done with collaborators at University of Pennsylvania (UPenn) School of Medicine, Massachusetts General Hospital (MGH), and the Broad Institute. The collaborative effort combined genome-wide association studies (GWAS) and RNAi technology to identify and validate novel genes as targets for new therapies for heart disease.

Dermatologist discusses treatment for acne and melasma

The U.S. Census Bureau predicts that the Asian-American population will total 40 million people by 2050. While as a whole this group is characterized by very dark hair and dark eyes, there is much diversity in Asian skin tones – from very light, pale skin to light or dark brown skin. One common thread is the pigmentation issues that Asian Americans often face as after-effects of other dermatologic problems that can be as troublesome as the original condition itself.

New research on use of medicine, diet to prevent UV-induced skin cancer

In most cases, non-melanoma skin cancers are caused by overexposure to ultraviolet radiation - the invisible rays from the sun that can burn the skin. To reduce the risk of skin cancer, dermatologists encourage the public to Be Sun Smart, including limiting sun exposure and using broad-spectrum sunscreens.

Scientists identify genetic variant that increases risk of schizophrenia

A group of scientists has identified a genetic variant that substantially increases the risk for developing schizophrenia in Ashkenazi Jewish and other populations. The study, published by Cell Press on August 5th in the American Journal of Human Genetics, associates a deletion on chromosome 3 with increased incidence of schizophrenia.

Vesicular stomatitis virus kills tumour, stimulates immune response against cancer: Research

Cancer Research UK scientists have used the immune system coupled with a virus found in horses and cattle, to hunt and purge cancer cells through the lymphatic system, a study reveals in Nature Medicine.Studying mice, the researchers found that the vesicular stomatitis virus (VSV), carried by a type of white blood cell called T cells acted as a 'cancer hunter', tracking down tumour cells in the lymph nodes, liver and spleen, and killed them, leaving normal healthy cells unharmed. At the same time, VSV also helped to trigger an immune response against the tumour, significantly improving the anti-cancer effect.

Scientists find new way to make beating heart cells from body's own cells

Scientists at the Gladstone Institute of Cardiovascular Disease have found a new way to make beating heart cells from the body's own cells that could help regenerate damaged hearts. Over 5 million Americans suffer from heart failure because the heart has virtually no ability to repair itself after a heart attack.

Scientists find molecular cocktail to transform non-muscle cells into cardiac muscle

In heart disease, cardiac muscle gradually dies off and, with little or no way to regenerate those cells, that can ultimately lead the heart to fail. But scientists reporting in the August 6th issue of Cell, a Cell Press publication, might have found a way to fix those losses. They've devised a three-ingredient molecular cocktail that transforms fibroblasts - structural cells that the heart is chock full of - directly into beating heart cells.
