Researchers develop durable antibacterial coatings of nanocomposites

Ruthless with bacteria, harmless to human cells. New, durable antibacterial coatings of nanocomposites, developed at the Institute of Physical Chemistry of the Polish Academy of Sciences in Warsaw, will in future help to improve the hygiene of sportswear, and used in medicine, will reduce the rate of infections and shorten the times of in-patient hospital admissions.

Epigenome-wide association study helps discover genes linked to allergies and asthma

Researchers from Canada, the UK, Sweden and the US have discovered more than 30 genes that strongly affect an antibody involved in allergies and asthma. Some of the genes could provide targets for drugs to treat those conditions, according to the international team's study, published online in Nature on Feb. 18.

Industrial Biotechnology presents insights on cellulose nanocrystal toxicity

Novel nanomaterials derived from cellulose have many promising industrial applications, are biobased and biodegradable, and can be produced at relatively low cost. Their potential toxicity--whether ingested, inhaled, on contact with the skin, or on exposure to cells within the body--is a topic of intense discussion, and the latest evidence and insights on cellulose nanocrystal toxicity are presented in a Review article in Industrial Biotechnology, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers.

Philadelphia College of Osteopathic Medicine professor explores causes, treatments of anorexia

Eating disorders are serious, debilitating conditions associated with significant morbidity and mortality, and distress. Anorexia nervosa, in particular, is associated with the highest mortality and suicide rates; compared to healthy peers, women with anorexia are up to 12 times more likely to die of any cause, and approximately 57 times more likely to die from suicide, over the same period of time.

New partnership aims to create stem cell resource to study psychiatric disorders

The New York Stem Cell Foundation and the Stanley Center at the Broad Institute of MIT and Harvard are partnering to create a foundational stem cell resource to study psychiatric disorders through the production of induced pluripotent stem (iPS) cell lines from individuals with schizophrenia and other psychiatric disorders.

Study: Growth hormone can improve social impairment in patients with Phelan-McDermid syndrome

A growth hormone can significantly improve the social impairment associated with autism spectrum disorder (ASD) in patients with a related genetic syndrome, according to a pilot study conducted at the Icahn School of Medicine at Mount Sinai and published yesterday on Pub Med, a public database of biomedical topics maintained by the National Institutes of Health (study originally published in the December 12 issue of the journal Molecular Autism).

IUPUI's Jason Meyer awarded $1.8 million NIH grant to explore how glaucoma develops in stem cells

Jason Meyer, Ph.D., assistant professor of biology in the School of Science at Indiana University-Purdue University Indianapolis, has received a National Institutes of Health grant to study how glaucoma develops in stem cells created from skin cells genetically predisposed to the disease.

New research finds that synthetic flame retardants can cause metabolic and liver problems

Chemicals used as synthetic flame retardants that are found in common household items such as couches, carpet padding, and electronics have been found to cause metabolic and liver problems that can lead to insulin resistance, which is a major cause of obesity, according to new research from the University of New Hampshire.

Evolution of two protein kinases may hold key to unlocking highly specific cancer drugs

This is the story of Abl and Src -- two nearly identical protein kinases whose evolution may hold the key to unlocking new, highly specific cancer drugs.

New study turns to epigenetics to look for new therapeutic targets to treat allergic diseases

Scientists have discovered over 30 new genes that predispose people to allergies and asthma, some of which could be targets for new drugs.

Scientists identify promising new therapeutic target for prostate cancer

Keck Medicine of the University of Southern California scientists have found a promising new therapeutic target for prostate cancer. The findings offer evidence that a newly discovered member of a family of cell surface proteins called G-protein coupled receptors (GPCRs) promotes prostate cancer cell growth. The protein, GPR158, was found while the researchers were looking for new drug targets for glaucoma.

Korean scientists produce flexible, stable monolayers of protein-bound gold nanoparticles

Free-standing nanoparticle films are of great interest for technical applications, such as the development of nanoelectronic devices. In the journal Angewandte Chemie, Korean scientists have introduced very flexible and stable monolayers of gold nanoparticles made by a self-assembly process based on protein aggregation. The films were used to coat wafers up to 10 cm in diameter.

Targeting pericytes and ANG2 signaling may help treat certain breast cancers

Tumors require blood to emerge and spread. That is why scientists at The University of Texas MD Anderson Cancer Center believe that targeting blood vessel cells known as pericytes may offer a potential new therapeutic approach when combined with vascular growth factors responsible for cell death.

Study helps solve mystery about how genetic variations can increase cancer risk

Single-letter genetic variations within parts of the genome once dismissed as 'junk DNA' can increase cancer risk through wormhole-like effects on far-off genes, new research shows.

New study links chicken pox and shingles virus to giant cell arteritis in elderly

A new study links the virus that causes chicken pox and shingles to a condition that inflames blood vessels on the temples and scalp in the elderly, called giant cell arteritis. The study is published in the February 18, 2015, online issue of Neurology, the medical journal of the American Academy of Neurology. The condition can cause sudden blindness or stroke and can be life-threatening.
