Scientists create germ cell-supporting embryonic Sertoli-like cells from skin cells

CAMBRIDGE, Mass. (September 6, 2012) – Using a stepwise trans-differentiation process, Whitehead Institute researchers have turned skin cells into embryonic Sertoli-like cells.

Transformation of health system needed to improve care and reduce costs

WASHINGTON — America's health care system has become too complex and costly to continue business as usual, says a new report from the Institute of Medicine. Inefficiencies, an overwhelming amount of data, and other economic and quality barriers hinder progress in improving health and threaten the nation's economic stability and global competitiveness, the report says. However, the knowledge and tools exist to put the health system on the right course to achieve continuous improvement and better quality care at lower cost, added the committee that wrote the report.

Human genome far more active than thought

The GENCODE Consortium expects the human genome has twice as many genes than previously thought, many of which might have a role in cellular control and could be important in human disease. This remarkable discovery comes from the GENCODE Consortium, which has done a painstaking and skilled review of available data on gene activity.

Childhood sexual abuse linked to later heart attacks in men

TORONTO, ON – Men who experienced childhood sexual abuse are three times more likely to have a heart attack than men who were not sexually abused as children, according to a new study from researchers at the University of Toronto. The researchers found no association between childhood sexual abuse and heart attacks among women.

Promising new drug target for inflammatory lung diseases

New Rochelle, NY, September 6, 2012—The naturally occurring cytokine interleukin-18, or IL-18, plays a key role in inflammation and has been implicated in serious inflammatory diseases for which the prognosis is poor and there are currently limited treatment options.

Advanced maternal age not harmful for adult children

Multi-functional anti-inflammatory/anti-allergic developed by Hebrew University researcher

Jerusalem, Sept. 6, 2012 – A synthetic, anti-inflammatory and anti-allergic family of drugs to combat a variety of illnesses while avoiding detrimental side effects has been developed by a Hebrew University of Jerusalem researcher.

The researcher is Saul Yedgar, who is the Walter and Greta Stiel Professor of Heart Studies at the Institute for Medical Research Israel-Canada at the Hebrew University Faculty of Medicine.

Pint-size microRNAs show promise against weighty problem, researchers say

Tiny strands of RNA affect how our cells burn fat and sugar — a finding that gives biologists a place to start in the quest for therapies to treat obesity and related health problems, said scientists at Virginia Tech and the University of Texas Southwestern Medical Center at Dallas.

Mice on high fat diets are resistant to obesity when two mini-molecules called microRNAS are missing from their genetic makeup, according to a study this week in the Proceedings of the National Academy of Science

University of Hawaii cancer researchers discover gene defect responsible for cancer syndrome

HONOLULU, HI - University of Hawai'i Cancer Center researchers have discovered germline BAP1 mutations are associated with a novel cancer syndrome characterized by malignant mesothelioma, uveal melanoma, cutaneous melanoma and atypical melanocytic tumors. Germline mutations are hereditary gene defects that are present in every cell.

Students create low-cost biosensor to detect contaminated water in developing nations

TEMPE, Ariz. – Diarrheal disease is the second leading cause of death in children under five years old — killing as many as 1.5 million children worldwide every year. These startling statistics from the World Health Organization (2009) point to the reason why a group of undergraduate students from Arizona State University is working to develop a low-cost biosensor — a simple device that would detect contaminated drinking water.

Novel therapeutic targets identified for small cell lung cancer

PHILADELPHIA — Newly discovered molecular differences between small cell lung cancer and nonsmall cell lung cancer have revealed PARP1 and EZH2 as potential therapeutic targets for patients with small cell lung cancer, according to the results of a study published in Cancer Discovery, a journal of the American Association for Cancer Research.

Breast cancer screening saves lives, new study shows

The study, published today in Cancer Epidemiology, Biomarkers and Prevention is the largest of its kind in Australia and one of the largest in the world. It followed about 4,000 women in a study of the BreastScreen program in Western Australia.

University of Melbourne Research Fellow Dr Carolyn Nickson and colleagues from the Melbourne School of Population Health said the findings reaffirmed the importance and efficacy of mammography.

Chikyu sets a new world drilling-depth record of scientific ocean drilling

Off Hachinohe, Japan—Scientific deep sea drilling vessel Chikyu sets a world new record by drilling down and obtains rock samples from deeper than 2,111 meters below the seafloor off Shimokita Peninsula of Japan in the northwest Pacific Ocean. The Japan Agency for Marine-Earth Science and Technology (JAMSTEC), the implementing organization for scientific expedition aboard the Chikyu, announced this achievement on 6th September, 2012.

Almost 1 in 5 young children with cancer suffers from a trauma disorder

People who suffer from posttraumatic stress disorder relive their traumatic experiences in the form of flashbacks and nightmares – and in childhood, also in traumatic plays during which they re-enact the experience over and over again. They avoid stimuli that remind them of the trauma or suffer from vegetative hyperarousal such as insomnia, hypervigilance or concentration problems.

Joint EACPR and AHA statement empowers health care professional to use Clinical Cardiopulmonary Exercise Testing

Sophia Antipolis, 6 September 2012: The European Association for Cardiovascular Prevention and Rehabilitation (EACPR), a registered branch of the European Society of Cardiology (ESC), and the American Heart Association (AHA) have today issued a joint scientific statement http://eurheartj.oxfordjournals.org/content/early/2012/08/24/eurheartj.ehs221.short?rss=1 that sets out to produce easy-to-follow guidance on Clinical Cardiopulmonary Exercise (CPX) testing
