New role for DNA methylation in subset of premature aging disorder patients

2013-02-01
(Press-News.org) Scientists at the Bellvitge Biomedical Research Institute in Barcelona, Spain have found new evidence for the role of epigenetic changes (those heritable alterations in gene expression caused by mechanisms other than changes in DNA sequence) on premature aging diseases. A new study published in the journal Epigenetics on Jan. 1, 2013, identified a role for DNA methylation changes in a subset of Hutchinson-Gilford Progeria and Werner Syndrome patients, for which no genetic cause (such as DNA mutation) had been associated with onset disease. The study, titled "Aberrant DNA methylation profiles in the premature aging disorders Hutinson-Gilford Progeria and Werner syndrome," is available at http://www.landesbioscience.com/journals/epigenetics/article/23366/.

### Epigenetics is a multidisciplinary peer-reviewed journal that publishes original research and review articles covering the latest findings about epigenetic mechanisms and their role in diverse biological processes. Established in 1997, Landes Bioscience is an Austin, Texas-based publisher of biology research journals and books.

Safe sex practices among African American women

2013-02-01
Los Angeles, CA (January 31, 2013) Researchers have found that African American women exhibit a higher risk for sexually transmitted infections including HIV/Aids. But what motivates this group of women to have sex? And when are they more likely to use protection? A new study published today in Health Education & Behavior (a SAGE journal) found that regardless of motivations for having sex, condom use expectations were less than 50% for all types of sexual encounters, including the riskiest types of sex. Researchers Julianna Deardorff et. al used a combination of interviews ...

Men taking long-acting chronic pain meds 5xs more likely to have low testosterone levels

2013-02-01
OAKLAND, Calif., January 31, 2013 — Low testosterone levels occur five times more often among men who take long-acting instead of short-acting opioids for chronic pain, according to a new Kaiser Permanente study published in The Clinical Journal of Pain. While it has been known that opioids cause low testosterone in men, this study is the first to show a significant difference in risk between short-acting (immediate release) and long-acting opioids. The 81 men in the retrospective study were between 26 and 79 years old (median age 51) and were seen in the chronic-pain ...

New device traps particulates, kills airborne pathogens

2013-02-01
A new device called a soft x-ray electrostatic precipitator protected immunocompromised mice from airborne pathogenic bacteria, viruses, ultrafine particles, and allergens, according to a paper published online ahead of print in the journal Applied and Environmental Microbiology. This device, known for short as a SXC ESP, is highly versatile, with multiple potential uses, and Washington University is working on licensing the technology. "Small particles are difficult to remove, and our device overcomes that barrier," says Pratim Biswas of Washington University, St. Louis. ...

Mutant gene responsible for pigeons' head crests

Mutant gene responsible for pigeons head crests
2013-02-01
Scientists have decoded the genetic blueprint of the rock pigeon, unlocking secrets about pigeons' Middle East origins, feral pigeons' kinship with escaped racing birds and how mutations give pigeons traits like feather head crests. "Birds are a huge part of life on Earth, but we know surprisingly little about their genetics," says Michael Shapiro, one of the study's two principal authors and a biologist at the University of Utah. In the new study, "we've shown a way forward to find the genetic basis of traits--the molecular mechanisms controlling animal diversity in ...

Just 11 percent of adults, 5 percent of children participate in medical research

2013-02-01
ANN ARBOR, Mich. – Medical research is vital to the advancement of health care, but many medical research studies have too few people who participate. A new study from the University of Michigan takes an in-depth look at public participation in medical research across the United States. Through a unique, nationally representative survey of 2,150 households in 2011, University of Michigan researchers found that only 11% of adults and 5% of children had ever participated in medical research. The study was published in January in Clinical and Translational Science. About ...

2-step immunotherapy attacks advanced ovarian cancer

2013-02-01
PHILADELPHIA -- Most ovarian cancer patients are diagnosed with late stage disease that is unresponsive to existing therapies. In a new study, researchers from the Perelman School of Medicine at the University of Pennsylvania School of Medicine show that a two-step personalized immunotherapy treatment — a dendritic cell vaccine using patients' own tumor followed by adoptive T cell therapy — triggers anti-tumor immune responses in these type of patients. Four of the six patients treated in the trial responded to the therapy, the investigators report this month in OncoImmunology. ...

Nurses at forefront of genomics in healthcare

2013-02-01
On April 14, 2003 a map of the human genome was completed, ushering in a new era of genetics in medicine with applications that include genetic testing; newborn screening; susceptibility to diseases such as cancer, cardiovascular disease, or psychiatric conditions; screening, diagnosis and monitoring of disease; and treatment planning. A special Genomics Issue, including an evidence review by researchers from the National Institutes of Health (NIH), published by Wiley in the Journal of Nursing Scholarship on behalf of the Honor Society of Nursing, Sigma Theta Tau International, ...

Virginia Tech adjunct and colleagues refute a study on 'racial bias' report in NIH awards

Virginia Tech adjunct and colleagues refute a study on racial bias report in NIH awards
2013-02-01
In a recent article in the Chronicle of Higher Education, the National Institutes of Health (NIH) announced it was considering anonymity in the review of grant applications. (Found at: http://chronicle.com/article/NIH-Considers-Anonymity-for/136227/?cid=pm&utm_source=pm&utm_medium=en ) Ge Wang, adjunct professor of biomedical engineering at the Virginia Tech – Wake Forest University School of Biomedical Engineering and Sciences, and seven of his colleagues do not believe this action is necessary if taken to counteract a charge of "racial bias." For Wang, their study ...

Mental health parity reduces out of pocket expenses for patients

2013-02-01
Belmont, MA—In a study examining the impact of a parity policy for mental health insurance benefits, researchers have concluded that parity had a different impact on spending and service utilization for enrollees with illnesses that are more severe and chronic. As a result of the parity policy, individuals seeking treatment for major depression or bipolar disorder had lower out-of-pocket spending, despite no significant difference in the amount of behavioral health services they used. However, individuals with adjustment disorder (a less severe, acute illness) had lower ...

New report: State action on Affordable Care Act's 2014 health insurance market reforms

2013-02-01
New York, NY, February 1, 2013—Only 11 states and the District of Columbia have passed laws or issued regulations to implement the Affordable Care Act's major health insurance market reforms that go into effect in 2014, according to a new Commonwealth Fund report. Thirty-nine states have not yet taken action to implement these requirements, potentially limiting their ability to fully enforce the new reforms and ensure that consumers receive the full protections of the law. These reforms include bans on denying people health insurance due to preexisting conditions, a minimum ...
