Naturally occurring molecule may prevent plaque buildup inside arteries

Cleveland Clinic researchers have discovered that a naturally occurring molecule may play a role in preventing plaque buildup inside arteries, possibly leading to new plaque-fighting drugs and improved screening of patients at risk of developing atherosclerosis.

Oligodendroglia cells: An interview with Jeffrey Rothstein

There are three principle cells in the brain: neurons and two types of glial cells. One type is called an astrocyte. These were well known to inactivate neurotransmitters like glutamate, and provide metabolic support to neurons.

Research into “insulating” brain cells could help to cure neurodegenerative diseases such as ALS

Johns Hopkins researchers say they have discovered that the central nervous system's oligodendroglia cells, long believed to simply insulate nerves as they "fire" signals, are unexpectedly also vital to the survival of neurons. Damage to these insulators appears to contribute to brain injury in neurodegenerative diseases such as amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease for the Yankee baseball great who died from the disease.

Courtagen launches nucSEEKPDx assay

Courtagen Life Sciences, Inc., a privately held life sciences company that provides innovative proteomic and genomic products and services to the life sciences industry, today announced the expansion of their genetic test menu. The new genetic test, nucSEEKPDx, will sequence approximately 1,100 nuclear genes constituting the mitochondrial exome, which encodes the vast majority of proteins found in the mitochondrion. This test is by far the most comprehensive test on the market for the management of mitochondrial disorders.

Neonate blood-brain barrier more intact than adults following stroke

The ability for substances to pass through the blood-brain barrier is increased after adult stroke, but not after neonatal stroke, according to a new study the UCSF that will be published July 11 in the Journal of Neuroscience.

Breast cancer drug bevacizumab slows progression but has no overall survival benefit

The cancer drug bevacizumab (Avastin®) offers only a modest benefit in prolonging disease progression in patients with advanced stage breast cancer, according to a systematic review by Cochrane researchers. The researchers assessed the efficacy of bevacizumab in combination with chemotherapy, an established cancer treatment in this indication, and found no overall survival benefit when adding bevacizumab to chemotherapy.

Study details development of first mouse model for Usher syndrome III

A new study published in the July 11 issue of the Journal of Neuroscience details the development of the first mouse model engineered to carry the most common mutation in Usher syndrome III causative gene (Clarin-1) in North America.

Microbiologists reveal how T. brucei’s key proteins organize to replicate its mtDNA

A group of diseases that kill millions of people each year can't be touched by antibiotics, and some treatment is so harsh the patient can't survive it. They're caused by parasites, and for decades researchers have searched for a "magic bullet" to kill them without harming the patient. Now, a team of microbiologists at the University of Massachusetts Amherst has made an advance that could one day lead to a new weapon for fighting parasitic diseases such as African sleeping sickness, chagas disease and leishmaniasis.

Cylene's Pol I inhibitor activates p53 and selectively destroys cancer cells

Cylene Pharmaceuticals today announced that research collaborators at the Peter MacCallum Cancer Centre (Peter Mac) in Melbourne, Australia have established, for the first time, that RNA Polymerase I (Pol I) activity is essential for cancer cell survival and that its inhibition selectively activates p53 to kill tumors. Published today in Cancer Cell, the findings show that Cylene's Pol I inhibitor, CX-5461, selectively destroys cancer by activating p53 in malignant but not in normal cells.

TLR1 plays a critical role in protecting the body from food-borne illnesses

A naturally occurring protein called TLR1 plays a critical role in protecting the body from illnesses caused by eating undercooked pork or drinking contaminated water, according to new research from the University of Southern California (USC).

Researchers discover unknown mechanism that promotes growth and spread of cancer

Tiny vesicles released by tumors cells are taken up by healthy immune cells, causing the immune cells to discharge chemicals that foster cancer-cell growth and spread, according to a study by researchers at The Ohio State University Comprehensive Cancer Center - Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC - James) and at Children's Hospital in Los Angeles.

Research finds new single-gene cause of chronic kidney disease

A new single-gene cause of chronic kidney disease has been discovered that implicates a disease mechanism not previously believed to be related to the disease, according to new research from the University of Michigan.

Article addresses tremendous impact of genetic testing for Alzheimer’s

Genetic tests exist to identify risk for the rare inherited form of early-onset Alzheimer's disease (AD) and to predict susceptibility to the more common, late-onset form of AD, but do people want to know, and how do they react? The answers can be found in the article published in Genetic Testing and Molecular Biomarkers, a peer-reviewed journal from Mary Ann Liebert, Inc.

New method uses acoustic angiography to identify cancer in minutes

From the air, the twists and turns of rivers can easily be seen. In the body, however, tracing the twists and turns of blood vessels is difficult, but important. Vessel "bendiness" can indicate the presence and progression of cancer.

Book explains complex world of personalized medicine

Personalized medicine has promised to radically change the way we look at health and disease. Talk of tailored drug therapies and early detection of cancer has captured the attention of scientists and lay people alike. So when will patients start to reap the benefits of this medical revolution?

Nutrient cocktail can boost memory in patients with mild cognitive impairment

A clinical trial of an Alzheimer's disease treatment developed at MIT has found that the nutrient cocktail can improve memory in patients with early Alzheimer's. The results confirm and expand the findings of an earlier trial of the nutritional supplement, which is designed to promote new connections between brain cells.

New algorithm for faster human genome sequencing

In 2001, the Human Genome Project and Celera Genomics announced that after 10 years of work at a cost of some $400 million, they had completed a draft sequence of the human genome. Today, sequencing a human genome is something that a single researcher can do in a couple of weeks for less than $10,000.

SRI International receives DoD grant to develop novel therapy for MS

The Department of Defense (DoD) has awarded SRI International a one-year grant to develop a novel therapy for multiple sclerosis (MS), an autoimmune nervous system disease that affects about 400,000 people in the United States and more than two million people worldwide. There is currently no cure for this disorder, which can impair vision and movement.
