New laser technique could create tissue scaffolds, microneedles

In the emerging field of tissue engineering, scientists encourage cells to grow on carefully designed support scaffolds. The ultimate goal is to create living structures that might one day be used to replace lost or damaged tissue, but the manufacture of appropriately detailed scaffolds presents a significant challenge that has kept most tissue engineering applications confined to the research lab.

Promedior's Pentraxin-2 effectively suppresses liver fibrosis

Promedior, Inc., a clinical stage biotechnology company developing novel therapies to treat fibrotic, inflammatory and neovascular diseases, today announced that data from preclinical studies of Serum Amyloid P (Pentraxin-2) will be presented at the Annual Meeting of the American Association for the Study of Liver Diseases (AASLD 2011), being held November 4-8, 2011, in San Francisco, CA.

Study reveals new role for the 'hormone of love'

Much of the body's chemistry is controlled by the brain - from blood pressure to appetite to food metabolism. In a study published recently in Developmental Cell, a team of scientists led by Dr. Gil Levkowitz of the Weizmann Institute has revealed the exact structure of one crucial brain area in which biochemical commands are passed from the brain cells to the bloodstream and from there to the body. In the process, they discovered a surprising new role for the 'hormone of love,' showing that it helps to direct the development of this brain structure.

UC Merced professor designs powerful chemical inhibitor against HIV

In a significant step toward reducing the threat of HIV, UC Merced Professor Patricia LiWang has designed what may be the most effective chemical inhibitor against infection of the virus.

Nicotine might prime the brain to enhance behavioral effects of cocaine

A landmark study in mice identifies a biological mechanism that could help explain how tobacco products could act as gateway drugs, increasing a person's future likelihood of abusing cocaine and perhaps other drugs as well, according to the National Institute on Drug Abuse (NIDA), part of the National Institutes of Health. The study is the first to show that nicotine might prime the brain to enhance the behavioral effects of cocaine.

IP-K and Sanofi form new HBV research collaboration

One of the most common and serious infectious diseases, Hepatitis B, is to be targeted in a new collaborative venture between the internationally-renowned translational research institute, Institut Pasteur Korea (IP-K), and the Korean arm of the leading global healthcare company, Sanofi-Aventis Korea. The goal is to develop and validate a high throughput assay to screen IP-K's chemical libraries for novel compounds that can be developed as new drugs.

Cypin protein may prevent long-term brain damage after stroke

One of two proteins that regulate nerve cells and assist in overall brain function may be the key to preventing long-term damage as a result of a stroke, the leading cause of disability and third leading cause of death in the United States.

Nmnat1 protein may help prevent brain damage in babies with cerebral palsy

Scientists at Washington University School of Medicine in St. Louis have shown that a protein may help prevent the kind of brain damage that occurs in babies with cerebral palsy.

Broader screening for hypertrophic cardiomyopathy

Around one in 500 Swedes carry a genetic mutation which can cause sudden cardiac death. The diagnosis can lead to major lifestyle changes, but quality of life can be maintained with the right advice and support, reveals a new study from the Sahlgrenska Academy at the University of Gothenburg, Sweden.

Radiation therapy prior to HCT improves outcomes in older patients with hematologic malignancies

Older patients with advanced hematologic malignancies, such as leukemia and lymphoma, who received a conditioning regimen that included minimal-intensity radiation therapy prior to allogeneic hematopoietic cell transplantation had survival and progression-free survival outcomes suggesting that this treatment approach may be a viable option for older patients with these malignancies, according to a study in the November 2 issue of JAMA.

SGI HPC systems selected for genomics research at Kyoto University's Institute for Chemical Research

SGI, the trusted leader in technical computing, announced today that the Institute for Chemical Research at Kyoto University in Kyoto, Japan, has selected an SGI high performance computing (HPC) and storage system to advance genomics research at the Institute.

HRM curve analysis identifies patients at risk of MH

A new DNA test may make it much simpler to identify patients at risk of malignant hyperthermia (MH)—a rare but life-threatening complication of exposure to common anesthetics reports the November issue of Anesthesia & Analgesia, official journal of the International Anesthesia Research Society.

Bacteria rapidly exchange genetic information related to human disease and antibiotic resistance

Much as people can exchange information instantaneously in the digital age, bacteria associated with humans and their livestock appear to freely and rapidly exchange genetic material related to human disease and antibiotic resistance through a mechanism called horizontal gene transfer (HGT).

Leeches shift the way they locate prey in adulthood

Many meat-eating animals have unique ways of hunting down a meal using their senses. To find a tasty treat, bats use echolocation, snakes rely on infrared vision, and owls take advantage of the concave feathers on their faces, the better to help them hear possible prey.

Scientists identify distinct tobacco transporter for nicotine metabolism

A team of Virginia Tech and Purdue University scientists have identified a distinct transporter used by tobacco plant cells for nicotine metabolism. The research appears in the Oct. 17 online before print issue of the Proceedings of the National Academy of Sciences (PNAS) in the article, "A tobacco nicotine uptake permease effects alkaloid metabolism."

Scientists pinpoint central elements of cell division

Scientists at Warwick Medical School have uncovered the molecular process of how cells are by-passing the body's inbuilt 'health checkpoint' with cells that carry unequal numbers of chromosomes that have a higher risk of developing cancer.

Inhibiting Notch signalling makes hormone-receptor positive cells dependent on estrogen

Within many hormone-receptor positive breast cancers lives a subpopulation of receptor-negative cells - knock down the hormone-receptor positive cells with anti-estrogen drugs and you may inadvertently promote tumor takeover by more dangerous, receptor-negative cells.

Researchers discover key enzymes that are critical for sperm function

Compared to most other cells in an organism, sperm undergo a radical transformation to become compact and mobile delivery systems for paternal DNA. Even though sperm looks and moves quite differently across species, SF State researcher Diana Chu and colleagues now say that there are at least a few key enzymes that are critical for sperm development and mobility in species as different as mice and nematode worms.

PSTC, FNIH Biomarkers Consortium launch clinical study to improve detection of kidney injury

The Foundation for the National Institutes of Health (FNIH) Biomarkers Consortium announced today the launch of a two-year clinical study aiming to advance the acceptance of new biomarkers designed to detect drug-induced kidney injury in clinical trials.
