Researchers find way to prevent noise-induced hearing loss

Researchers from Weill Cornell Medical College and the Gladstone Institutes have found a way to prevent noise-induced hearing loss in a mouse using a simple chemical compound that is a precursor to vitamin B3. This discovery has important implications not only for preventing hearing loss, but also potentially for treating some aging-related conditions that are linked to the same protein.

Researchers create synthetic surface to control adhesion of E. coli bacteria

A research team from Kiel University and Goethe University Frankfurt has jointly created a synthetic surface on which the adhesion of E. coli bacteria can be controlled. The layer, which is only approximately four nanometres thick, imitates the saccharide coating (glycocalyx) of cells onto which the bacteria adhere such as during an infection. This docking process can be switched on and off using light.

BWH researchers identify cells responsible for fibrosis

Researchers from Brigham and Women's Hospital have identified what they believe to be the cells responsible for fibrosis, the buildup of scar tissue. Fibrotic diseases, such as chronic kidney disease and failure, lung disease, heart failure and cirrhosis of the liver, are estimated to be responsible for up to 45 percent of deaths in the developed world.

Researchers identify possible prognostic biomarker in triple-negative breast cancer

"Triple-negative" breast cancer (TNBC) occurs in patients whose cells do not express receptors for estrogen, progesterone, and/or human epidermal growth factor receptor 2 (ER-/PR-/HER2-).

Children with change in SUFU gene more likely to develop brain tumour

Gorlin syndrome causes an increased risk of developing cancers of the skin and, rarely, in the brain. Around 1 in 30,000 people has the condition.

New therapeutic targets can prevent scarring within transplanted kidneys

Kidneys donated by people born with a small variation in the code of a key gene may be more likely, once in the transplant recipient, to accumulate scar tissue that contributes to kidney failure, according to a study led by researchers at the Icahn School of Medicine at Mount Sinai and published today in the Journal of Clinical Investigation.

UT Austin researchers identify network of genes that drives alcohol dependence

Researchers at The University of Texas at Austin have identified a network of genes that appear to work together in determining alcohol dependence. The findings, which could lead to future treatments and therapies for alcoholics and possibly help doctors screen for alcoholism, are being published this week in the journal Molecular Psychiatry.

HIV's ability to cause AIDS is declining, finds new research

The rapid evolution of HIV, which has allowed the virus to develop resistance to patients' natural immunity, is at the same time slowing the virus's ability to cause AIDS, according to new research funded by the Wellcome Trust.

Researchers explore how to turn on the activity of paternal gene

Most genes are inherited as two working copies, one from the mother and one from the father. However, in a few instances, a gene is imprinted, which means that one copy is silenced. This is called genomic imprinting. If the active copy is mutated, then disease results, even though the silenced gene copy may be normal.

Study paves way for further research on brain evolution

The neocortex is the part of the brain that enables us to speak, dream, or think. The underlying mechanism that led to the expansion of this brain region during evolution, however, is not yet understood. A research team headed by Wieland Huttner, director at the Max Planck Institute of Molecular Cell Biology and Genetics, now reports an important finding that paves the way for further research on brain evolution: The researchers analyzed the gyrencephaly index, indicating the degree of cortical folding, of 100 mammalian brains and identified a threshold value that separates mammalian species into two distinct groups: Those above the threshold have highly folded brains, whereas those below it have only slightly folded or unfolded brains.

Study shows how specific trauma changes into a state of generalized fear

"I can't get the memories out of my mind!... I am right back in Vietnam, in the middle of the monsoon season at my guard post. My hands are freezing, yet sweat pours from my entire body...I smell a damp sulfur smell. Suddenly I see what's left of my buddy Troy, his head on a bamboo platter, sent back to our camp by the Viet Cong."

SPLUNC1 protein binds to pulmonary lipids to fight lung infection

Scientists have taken an important step toward a new class of antibiotics aimed at stopping lung infections. They found that a protein found in large airways, called "SPLUNC1," binds to lipids critical to defending against bacterial and viral infections, as well as keeping lung tissue flexible and hydrated.
