New technique for identifying gene-enhancers

An international team led by researchers with the Lawrence Berkeley National Laboratory (Berkeley Lab) has developed a new technique for identifying gene enhancers - sequences of DNA that act to amplify the expression of a specific gene – in the genomes of humans and other mammals. Called SIF-seq, for site-specific integration fluorescence-activated cell sorting followed by sequencing, this new technique complements existing genomic tools, such as ChIP-seq (chromatin immunoprecipitation followed by sequencing), and offers some additional benefits.

Prostate treatment lasts, preserves fertility

SAN DIEGO (March 24, 2014)—Shrinking the prostate without surgery can provide long-term relief to men with this common condition that causes annoying symptoms, such as frequent trips to the bathroom, suggests a study of nearly 500 men. According to research being presented at the Society of Interventional Radiology's 39th Annual Scientific Meeting, 72 percent of men experienced symptom improvement three years after having a new, minimally invasive, image-guided treatment performed by interventional radiologists called prostate artery embolization (PAE).

Y-90 provides new, safe treatment for metastatic breast cancer

SAN DIEGO (March 24, 2014)—A minimally invasive treatment that delivers cancer-killing radiation directly to tumors shows promise in treating breast cancer that has spread to the liver when no other treatment options remain, according to research being presented at the Society of Interventional Radiology's 39th Annual Scientific Meeting. In the largest study of its kind to date, researchers reviewed treatment outcomes of 75 women (ages 26-82) with chemotherapy-resistant breast cancer liver metastases, which were too large or too numerous to treat with other therapies.

The increasing inefficiency of private health insurance in Canada

The gap between private health insurance premiums and payouts in Canada has widened markedly over the past 20 years, with a gap of $6.8 billion in 2011. In an analysis in CMAJ, Michael Law and coauthors examine why this has happened and how the private insurance industry might be better regulated for the benefit of those insured.

Nurses effective at treating common arm injury in kids, but docs do it better

A clinical trial to determine if nurses in the emergency department could reduce "pulled elbows" in children at a rate similar to that of physicians found that althiough nurses were able to treat this common injury 85% of the time, physicians were more effective, with a 97% success rate. The trial is published Mar. 24 in CMAJ (Canadian Medical Association Journal).

Canadians spend more on private health insurance for smaller payouts

Spending by Canadians on private health insurance has more than doubled over the past 20 years, but insurers paid out a rapidly decreasing proportion as benefits, according to a study published today in the CMAJ (Canadian Medical Association Journal).

The study, by University of British Columbia and University of Toronto researchers, shows that overall Canadians paid $6.8 billion more in premiums than they received in benefits in 2011.

Researchers issue state-of-the-state on genetic-based testing & treatment for breast cancer

(Lebanon, NH, 03/24/2014)- Dartmouth researchers at its Norris Cotton Cancer Center have compiled a review of the role that information gathered through genetic testing plays in the diagnosis and treatment of breast cancer. The paper entitled "Personalized Therapy for Breast Cancer" was accepted on March 17, 2014, for publication in Clinical Genetics. The paper discusses targeted therapies, new biomarkers, and the quality of commercially available testing methods.

Leukemia caused by chromosome catastrophe

Researchers have found that people born with a rare abnormality of their chromosomes have a 2,700-fold increased risk of a rare childhood leukaemia. In this abnormality, two specific chromosomes are fused together but become prone to catastrophic shattering.

World's first light-activated antimicrobial surface that also works in the dark

Researchers at UCL have developed a new antibacterial material which has potential for cutting hospital acquired infections. The combination of two simple dyes with nanoscopic particles of gold is deadly to bacteria when activated by light - even under modest indoor lighting. And in a first for this type of substance, it also shows impressive antibacterial properties in total darkness.

The research, from by Sacha Noimark and Ivan Parkin (both UCL Chemistry) and Elaine Allan (UCL Eastman Dental Institute), is published today in the journal Chemical Science.

Increased awareness about skin cancer needed for minorities

DETROIT – More awareness about skin cancer is needed for minorities because they believe they are at low risk of developing it, says Henry Ford Hospital dermatologist Diane Jackson-Richards, M.D.

Research has shown that minorities are diagnosed at a more advanced stage of skin cancer and have lower chances of survival than Caucasians. Squamous cell carcinoma is the most common skin cancer among African Americans and Asian Indians, and the second most common skin cancer in Hispanics, East Asians and Caucasians, according to the Skin Cancer Foundation.

Maturitas publishes position statement on management of vertebral osteoporotic fracture

Amsterdam, March 24, 2014 – Elsevier, a world-leading provider of scientific, technical and medical information products and services, today announced the publication of a position statement by the European Menopause and Andropause Society (EMAS) in the journal Maturitas on the topic of the management of postmenopausal women with vertebral osteoporotic fracture.

Protein called YAP gives blood vessels strength, shape

AUGUSTA, Ga. - A protein known to promote cancer appears to give the blood vessels strength and shape, researchers report.When yes-associated protein, or YAP, is deleted from vascular smooth muscle cells during development, the protein makes thin-walled blood vessels that over-dilate in response to the usual pressure of blood flow, said Dr. Jiliang Zhou, vascular biologist at the Medical College of Georgia at Georgia Regents University.

From mouse ears to man's?

One in a thousand children in the United States is deaf, and one in three adults will experience significant hearing loss after the age of 65. Whether the result of genetic or environmental factors, hearing loss costs billions of dollars in healthcare expenses every year, making the search for a cure critical.

Guarding grapes and other tales from papyri

If you weren't careful, you might end up beaten by grape thieves skulking in the darkness.

A University of Cincinnati graduate student writes about the contractual obligations of vineyard guards and researchers from around the world contribute more stories from ancient times in the most recent volumes of the Bulletin of the American Society of Papyrologists (BASP).

Hot nanoparticles for cancer treatments

This news release is available in German.

If you put your hand over a switched-on torch in the dark, it appears to glow red. This is because long-wavelength red light beams penetrate human tissue more effectively than short-wavelength blue light. ETH Zurich researchers exploit this fact in a new kind of nanoparticles: so-called plasmonic particles, which heat up when they absorb near-infrared light. This could enable them to kill tumour tissue with heat, for instance.
