New medicines to target LPA receptors may prevent serious developmental brain diseases

Examining brain damage that occurs when fetuses in the womb are deprived of oxygen, researchers at The Scripps Research Institute have discovered that damage does not occur randomly but is linked to the specific action of a naturally occurring fatty molecule called LPA, acting through a receptor that transfers information into young brain cells.

Scientists identify molecular pathway that plays a key role in stress-related DNA damage

Working closely with a team of researchers from Duke University, scientists from the Florida campus of The Scripps Research Institute have helped identify a molecular pathway that plays a key role in stress-related damage to the genome, the entirety of an organism's hereditary information.

Longer looks: Treating Down syndrome?; mentally ill, meds & trials

Politicians want to lower spending, or at least they say they do. But in all the to-and-fro over raising the debt ceiling, little sensible has been said about lowering spending in the long term. Nothing illuminates this more clearly than health care.

New fluorescent tool can track mysterious workings of cellular RNAs

The ability to tag proteins with a green fluorescent light to watch how they behave inside cells so revolutionized the understanding of protein biology that it earned the scientific teams who developed the technique Nobel Prizes in 2008.

Insight into Fragile X Syndrome and autism

Researchers now have a much clearer understanding of how mutations in a single gene can produce the complex cognitive deficits characteristic of Fragile X Syndrome, the most common inherited form of intellectual disability.

Scientists identify de novo mutations linked to schizophrenia

De novo mutations - genetic errors that are present in patients but not in their parents - are more frequent in schizophrenic patients than in normal individuals, according to an international group of scientists led by Dr. Guy A. Rouleau of the University of Montreal and CHU Sainte-Justine Hospital.

Fruit flies with poor posture help scientists understand human intellectual disability

Clumsy fruit flies with poor posture are helping an international team of scientists understand inherited intellectual disability in humans - and vice versa.

Potential new treatment for rare, inherited metabolic disease

The rare disorder alpha-mannosidosis can cause serious damage to the nervous system and other organ systems. In Tromsø, Norway, researchers have been studying the disease for 20 years - and a treatment may soon be available.

Mother and baby cytomegalovirus screening important to prevent consequences

According to health experts, pregnant women and newborns should be screened for a virus that causes brain damage and deafness. The study that appeared in the latest issue of The Medical Journal of Australia yesterday says hundreds of cases of cytomegalovirus (CMV) are likely being missed each year in Australia because of a lack of screening, denying babies treatment for the condition.

Synaptophysin controls replacement of vesicles

A University of Wisconsin-Madison research team has solved a 25-year mystery that may lead to better treatments for people with learning deficits and mental retardation.

Pre-implantation genetic diagnosis can avoid mother to child transmission of mtDNA disorders

Dutch researchers have developed a test which predicts which mothers at risk of passing on mitochondrial genetic disease to their children are likely to have a healthy baby.

New genomics research on abnormal brain development

Local researchers are finally on the road to developing targeted treatments for serious, life-long disabilities such as autism and schizophrenia, thanks to new genomics research focusing on abnormal brain development.

Researchers uncover new details of unusual biological mechanism in brains of diverse species

Researchers at the University of California, San Diego School of Medicine have uncovered new details of an unusual biological mechanism in the brains of diverse species that not only helps regulate how their brains develop, but also how they function later in life. The discovery could lead to new biomarkers for specific neurological diseases in humans and, possibly, the development of drugs to cure them.

Fragile X syndrome may be treatable

Advancements over the last 10 years in understanding intellectual disability (ID, formerly mental retardation), have led to the once-unimaginable possibility that ID may be treatable, a review of more than 100 studies on the topic has concluded. It appears in ACS Chemical Neuroscience.

New genetic discovery in megalencephalic leukoencephalopathy with subcortical cysts

White matter disease covers a large group of disorders that affect the white matter, or myelin. In children these disorders are commonly genetic and often go undiagnosed. In new research, a team led by Raúl Estévez, a lecturer from the Department of Physiological Sciences II, based at the UB's Bellvitge Health Sciences Campus, working with the researcher Marjo van der Knaap, from the University Medical Centre at VU University Amsterdam, have identified mutant GLIALCAM as responsible for 25% of cases of megalencephalic leukoencephalopathy with subcortical cysts, a rare genetic disease affecting cerebral myelin.

State roundup: Fla. hospitals divided public/private oversight; generous health benefits for Calif. elected officials

Hundreds of part-time elected officials throughout the Bay Area received full-time health care benefits in 2010 at taxpayer expense, with individual policies sometimes costing tens of thousands of dollars, according to government compensation data acquired by Bay Area News Group and published on its websites Sunday.

Scientists develop new method for enzyme immobilization

Virtually all processes in the human body rely on a unique class of proteins known as enzymes. To study them, scientists want to attach these molecules to surfaces and hold them fast, but this can often be a tricky undertaking.

First-of-its-kind map of recombination hotspots in a multi-celled organism

Researchers have zoomed in on mouse chromosomes to map hotspots of genetic recombination - sites where DNA breaks and reforms to shuffle genes. The findings of the scientists at the National Institutes of Health and Uniformed Services University of Health Sciences (USU) have the potential to improve the detection of genes linked to disease and to help understand the root causes of genetic abnormalities.

Asuragen introduces CE-mark approved AmplideX FMR1 PCR Kit

Asuragen, Inc. announced that they have achieved CE-marking and commercial launch in Europe of the AmplideX FMR1 PCR Kit for the detection of CGG repeats in the fragile X mental retardation gene.
