Researchers discover gene for new form of intellectual disability

Researchers at the Centre for Addiction and Mental Health (CAMH) led a study discovering a gene for a new form of intellectual disability, as well as how it likely affects cognitive development by disrupting neuron functioning.

Gas NO plays a fundamental regulatory role in controlling bacterial function

Bacteria provide a well-known playground for scientists and the evolution of these earliest life forms has shed important perspective on potential therapies for some of the most common, deadly diseases. Researchers at Case Western Reserve University School of Medicine have now discovered that, the gas nitric oxide (NO), produced in all cells of the human body for natural purposes, plays a fundamental regulatory role in controlling bacterial function, via a signaling mechanism called S-nitrosylation (SNO), which binds NO to protein molecules.

Funders should follow lead of U.S. in creating policies for scientific research oversight

"The controversy over the research into the genetic modification of the H5N1 flu virus, finally approved for publication, should offer a reminder of the importance of debate" over dual-use technology, a Nature editorial states.

Heart can regulate energy balance throughout the body

UT Southwestern Medical Center researchers have demonstrated for the first time that the heart can regulate energy balance throughout the body, a finding that may point to more effective treatments for obesity, diabetes, and heart disease.

Seabirds play an important role in dispersal and biodiversity of parasites

According to a scientific paper published in the journal Biology Letters, in which have taken part Jacob González-Solís, professor at the Department of Animal Biology and at the Biodiversity Research Institute of the University of Barcelona (IRBio), due to their capacity to travel long distances, seabirds play an important role in the dispersal and biodiversity of parasites and of the infectious agents these may transmit.

Researchers discover how adult brain can adapt to new situations

They say you can't teach an old dog new tricks. Fortunately, this is not always true. Researchers at the Netherlands Institute for Neuroscience have now discovered how the adult brain can adapt to new situations. The Dutch researchers' findings are published on Wednesday in the prestigious journal Neuron. Their study may be significant in the treatment of neurodevelopmental disorders such as epilepsy, autism and schizophrenia.

Study investigates possible links between maternal age and autism

In a study published in the May 2012 issue of the Journal of the American Academy of Child and Adolescent Psychiatry, led by Mr. Sven Sandin, of the Karolinska Institutet, Sweden and King's College London, researchers analyzed past studies to investigate possible associations between maternal age and autism. While much research has been done to identify potential genetic causes of autism, this analysis suggests that non-heritable and environmental factors may also play a role in children's risk for autism.

FDA approves Novartis’ Afinitor for treatment of renal angiomyolipomas and TSC

Novartis Pharmaceuticals Corporation announced today that the US Food and Drug Administration (FDA) approved Afinitor (everolimus) tablets for the treatment of adult patients with kidney tumors known as renal angiomyolipomas and tuberous sclerosis complex (TSC), who do not require immediate surgery.

Researchers examines whether MRI can improve accuracy of Huntington’s diagnosis

Huntington disease (HD) is an inherited neurodegenerative disorder caused by a defect on chromosome four where, within the Huntingtin gene, a CAG repeat occurs too many times. Most individuals begin experiencing symptoms in their 40s or 50s, but studies have shown that significant brain atrophy occurs several years prior to an official HD diagnosis. As a result, the field has sought a preventive treatment that could be administered prior to the development of actual symptoms that might delay the onset of illness.

Consumption of resistant starch leads to positive changes in the bowel

Consumption of resistant starch leads to positive changes in the bowel and could protect against genetic damage implicated in bowel cancer.

Novartis receives FDA approval for Afinitor to treat renal angiomyolipomas caused by TSC

The U.S. Food and Drug Administration approved Afinitor (everolimus), the first drug approved specifically to treat non-cancerous kidney tumors (renal angiomyolipomas) not requiring immediate surgery in patients with tuberous sclerosis complex.

U.S. government must be prepared to handle dual use research of concern

"This week, a Senate panel is investigating biological security in the wake of" controversial "potentially dangerous research" on H5N1 avian influenza, "with good reason," Rep. Jim Sensenbrenner (R-Wisc.) writes in a Washington Times opinion piece.

Helpful roles of rank, toxic substances

Usually, we think of mold, feces, nitric oxide, hydrogen sulfide and rat poison as rank, toxic or both. But scientists funded by the National Institutes of Health are learning more about the helpful roles these substances can play.

AAA to gather for anatomy meeting in conjunction with Experimental Biology 2012

The American Association of Anatomists will gather this week for its annual meeting in conjunction with the Experimental Biology 2012 conference, which will draw more than 14,000 scientists from industry, government and academia. Below are some programming highlights for the anatomy meeting. All presentations will be made at the San Diego Convention Center.

U of A develops new technology that enables personalized medicine

You wouldn't know it from appearances, but a metal cube the size of a toaster, created at the University of Alberta, is capable of performing the same genetic tests as most fully equipped modern laboratories-and in a fraction of the time.

IMPAKT 2012 breast cancer conference to focus on four major areas

"Basic science and clinical medicine move at different pace because they follow different paths. Both however aim at improving strategies to manage cancer patients. We need to efficiently translate the good things from basic science and efficiently implement them in the clinic."

Researchers identify new components of genetic pathway that controls neural stem cells

Can one feel too attached? Does one need to let go to mature? Neural stem cells have this problem, too. As immature cells, neural stem cells must stick together in a protected environment called a niche in order to divide so they can make all of the cells that populate the nervous system. But when it's time to mature, or differentiate, the neural stem cells must stop dividing, detach from their neighbors and migrate to where they are needed to form the circuits necessary for humans to think, feel and interact with the world.

CEHC develops list of ten chemicals that contribute to autism, learning disabilities

An editorial published today in the prestigious journal Environmental Health Perspectives calls for increased research to identify possible environmental causes of autism and other neurodevelopmental disorders in America's children and presents a list of ten target chemicals including which are considered highly likely to contribute to these conditions.

U-M’s second human embryonic stem cell line now available for federally-funded research

The University of Michigan's second human embryonic stem cell line has just been placed on the U.S. National Institutes of Health's registry, making the cells available for federally-funded research. It is the second of the stem cell lines derived at U-M to be placed on the registry.

Study shows how PCBs could add to autism risk

New research from UC Davis and Washington State University shows that PCBs, or polychlorinated biphenyls, launch a cellular chain of events that leads to an overabundance of dendrites - the filament-like projections that conduct electrochemical signals between neurons - and disrupts normal patterns of neuronal connections in the brain.
