New class of polymers resistant to bacterial attachment

Using state-of-the-art technology scientists at The University of Nottingham have discovered a new class of polymers that are resistant to bacterial attachment. These new materials could lead to a significant reduction in hospital infections and medical device failures.

Chronic nerve pain: researchers identify which sensory nerve cells are responsible

New research, led by academics at the University of Bristol and published in the journal Pain, has identified the subtypes of sensory nerve cells that are likely to contribute to long-term nerve pain from partial nerve injury. It is hoped this will aid in development of more effective pain killers.

Orally effective FluCide anti-influenza drug candidate

NanoViricides, Inc. announced today that an anti-influenza drug candidate under its FluCide program is effective when given orally. The Company has received information that a FluCide drug candidate designed for oral administration has shown very strong efficacy in corresponding animal studies.

Researchers uncover how pathological cells activate themselves in chronic lymphocytic leukaemia

Researchers in the group of Prof. Dr. Hassan Jumaa, Centre for Biological Signalling Studies (BIOSS) of the University of Freiburg, Department for Molecular Immunology, have identified a new mechanism that causes immune cells to convert into malignant cancer cells.

New 3-D view of the body's response to infection

A new 3-D view of the body's response to infection - and the ability to identify proteins involved in the response - could point to novel biomarkers and therapeutic agents for infectious diseases.

Insight into ubiquitin system

A faulty gene linked to a rare blood vessel disorder has led investigators to discover a mechanism involved in determining the fate of possibly thousands of proteins working inside cells.

Leukoaraiosis modifies brain function in the elderly

Researchers at the Mayo Clinic say a common condition called leukoaraiosis, made up of tiny areas in the brain that have been deprived of oxygen and appear as bright white dots on MRI scans, is not a harmless part of the aging process, but rather a disease that alters brain function in the elderly.

HDAC8 gene mutations cause Cornelia deLange syndrome

Genetics researchers have identified a key gene that, when mutated, causes the rare multisystem disorder Cornelia deLange syndrome (CdLS). By revealing how mutations in the HDAC8 gene disrupt the biology of proteins that control both gene expression and cell division, the research sheds light on this disease, which causes intellectual disability, limb deformations and other disabilities resulting from impairments in early development.

Study investigates why organisms retain seemingly unnecessary stages in their development

Why, after millions of years of evolution, do organisms build structures that seemingly serve no purpose? A study conducted at Michigan State University and published in the current issue of The American Naturalist investigates the evolutionary reasons why organisms go through developmental stages that appear unnecessary.

Johns Hopkins CIDR receives NIH contract to study genetic diseases

The Johns Hopkins Center for Inherited Disease Research (CIDR) program contract, which provides up to $101 million in research funding from the National Institutes of Health (NIH) to study the genetic contribution to human diseases, has been renewed for another five years.

Scientists discover why major depression or chronic stress can cause loss of brain mass

Major depression or chronic stress can cause the loss of brain volume, a condition that contributes to both emotional and cognitive impairment. Now a team of researchers led by Yale scientists has discovered one reason why this occurs - a single genetic switch that triggers loss of brain connections in humans and depression in animal models.

Research focuses on evolution of sex and gamete function

The propagation of every animal on the planet is the result of sexual activity between males and females of a given species. But how did things get this way? Why two sexes instead of one? Why are sperm necessary for reproduction and how did they evolve? These as-yet-unresolved issues fascinate Timothy Karr, a developmental geneticist and evolutionary biologist at Arizona State University's Biodesign Institute.

Scientists discover how pten gene causes brain changes that lead to autism-like behavior

Scientists affiliated with the UC Davis MIND Institute have discovered how a defective gene causes brain changes that lead to the atypical social behavior characteristic of autism. The research offers a potential target for drugs to treat the condition.

Reducing copper in the body delays onset of prion disease

Many of us are familiar with prion disease from its most startling and unusual incarnations-the outbreaks of "mad cow" disease (bovine spongiform encephalopathy) that created a crisis in the global beef industry. Or the strange story of Kuru, a fatal illness affecting a tribe in Papua New Guinea known for its cannibalism. Both are forms of prion disease, caused by the abnormal folding of a protein and resulting in progressive neurodegeneration and death.

Brain activity rapidly changes in olfactory regions following odor deprivation

Has a summer cold or mold allergy stuffed up your nose and dampened your sense of smell? We take it for granted that once our nostrils clear, our sniffers will dependably rebound and alert us to a lurking neighborhood skunk or a caramel corn shop ahead. That dependability is no accident. It turns out the brain is working overtime behind the scenes to make sure the sense of smell is just as sharp after the nose recovers.

Research on language gene seeks to uncover origins of the singing mouse

Singing mice (Scotinomys teguina) are not your average lab rats. Their fur is tawny brown instead of the common white albino strain; they hail from the tropical cloud forests in the mountains of Costa Rica; and, as their name hints, they use song to communicate.

Effects on white matter brain volume from long-term alcoholism are different for men and women

(Boston) - Researchers from Boston University School of Medicine (BUSM) and Veterans Affairs (VA) Boston Healthcare System have demonstrated that the effects on white matter brain volume from long-term alcohol abuse are different for men and women. The study, which is published online in Alcoholism: Clinical and Experimental Research, also suggests that with abstinence, women recover their white matter brain volume more quickly than men.
