Researchers discover cellular pathway that causes lung-damaging inflammation in CF

Vancouver researchers have discovered the cellular pathway that causes lung-damaging inflammation in cystic fibrosis (CF), and that reducing the pathway's activity also decreases inflammation.

Brain switches into special mode when pushed to make rapid decisions

Why do our brains make more mistakes when we act quickly? A new study demonstrates how the brain follows Ben Franklin's famous dictum, "Take time for all things: great haste makes great waste."

UC Irvine researchers create new stem cell-derived cell type for treatment of Alzheimer's

UC Irvine researchers have created a new stem cell-derived cell type with unique promise for treating neurodegenerative diseases such as Alzheimer's.

Calcium intake does not increase risk of coronary artery calcification

Researchers at the Institute for Aging Research (IFAR) at Hebrew SeniorLife, an affiliate of Harvard Medical School (HMS), have published a study that shows no evidence of a link between calcium intake and coronary artery calcification, reassuring adults who take calcium supplements for bone health that the supplements do not appear to result in the development of calcification of blood vessels.

Washington University, SRI investigators launch Global Metabolomic Initiative

Investigators at Washington University and The Scripps Research Institute have announced the launch of a "Global Metabolomic Initiative" to facilitate meta-analyses on studies of the metabolism of bacteria, yeast, plants, animals and people.

Duration of ibuprofen use may reduce risk of bladder cancer in northern New England patients

Dartmouth researchers have found that duration of ibuprofen use was associated with a reduced risk of bladder cancer in patients in northern New England, which has a high mortality rate of this disease. In a 2012 collaborative project with the National Cancer Institute, Margaret Karagas, PhD, co-director, Cancer Epidemiology & Chemoprevention program at Norris Cotton Cancer Center, and Professor of Community and Family Medicine at the Geisel School of Medicine at Dartmouth, and Richard Waddell, D.Sc, Research Assistant Professor of Medicine at the Geisel School of Medicine, looked for connections between ibuprofen use and bladder cancer.

WU researchers to study blood-clotting disorders

Researchers at Washington University School of Medicine in St. Louis have received a $9 million grant to investigate blood-clotting disorders. From heart attacks and strokes to uncontrolled bleeding, clotting disorders cause more deaths each year in the United States than all types of cancer combined.

Blind people’s brain can learn to process visual input with sounds

Areas of the brain in blind people can learn to process visual input through the use of sound, even after years or perhaps even lifelong blindness, according to new research reported in the November issue of the Cell Press journal Neuron. The findings challenge the common belief that if the visual cortex of the brain is deprived of information in early life, it may never develop functional specialization.

Atpif1 gene regulates hemoglobin synthesis during red blood cell formation

Researchers at Brigham and Women's Hospital (BWH) have discovered a new gene that regulates hemoglobin synthesis during red blood cell formation. The findings advance the biomedical community's understanding and treatment of human anemias and mitochondrial disorders.

Researchers sequence the DNA of 6,700 exomes of cystic fibrosis patients

A multi-institutional team of researchers has sequenced the DNA of 6,700 exomes, the portion of the genome that contains protein-coding genes, as part of the National Heart, Lung and Blood Institute (NHLBI)-funded Exome Sequencing Project, one of the largest medical sequencing studies ever undertaken.

Ion AmpliSeq Community Panels from Life Technologies

Life Technologies Corporation today announced Ion AmpliSeq Community Panels, a community-driven solution to gene panel sequencing that leverages the expertise of scientific thought leaders and the Ion Community to create gene panels for conditions ranging from cancer to inherited diseases.

Elafin protein protects against inflammatory diseases

This protection is provided by a human protein, Elafin, which is artificially introduced into dairy produce bacteria (Lactococcus lactis and Lactobacillus casei). In time, this discovery could be useful for individuals suffering from chronic inflammatory diseases such as Crohn's disease or ulcerative colitis.

Texas Biomed develops rapid, less expensive route to screen suitable tests for bioterror threats

Texas Biomedical Research Institute scientists in San Antonio have developed a faster, less expensive route to screen suitable tests for bioterror threats and accelerate the application of countermeasures.

Scientists show how sorafenib can be dangerous to the heart

Scientists for the first time have evidence showing how a widely used type of "targeted" cancer drug can be dangerous to the heart.

Excessive turnover of placental cells may trigger unnatural increase in blood pressure

Excessive turnover of cells in the placenta may trigger an unnatural increase in blood pressure that puts mother and baby at risk, researchers say.

Cloud technology helps researchers collect detailed information from cancer cell samples

Storing music and photos on distant computers via "cloud" technology is nothing new. But Johns Hopkins researchers are now using this tactic to collect detailed information from thousands of cancer cell samples. The goal is to help doctors make better predictions about how a patient's illness will progress and what type of treatment will be most effective.

Link between SFRP4 protein and risk of type 2 diabetes

When a patient is diagnosed with type 2 diabetes, the disease has usually already progressed over several years and damage to areas such as blood vessels and eyes has already taken place. To find a test that indicates who is at risk at an early stage would be valuable, as it would enable preventive treatment to be put in place.

Drug trio may reduce eliminate cardiac side effects of doxorubicin

Combining cancer medication with a drug for erectile dysfunction and one for heart transplants helped kill cancer cells and protected the heart from damage, in a study presented at the American Heart Association's Scientific Sessions 2012.

Alpha-herpesvirus axon-to-cell spread involves limited virion transmission

New research suggests that just one or two individual herpes virus particles attack a skin cell in the first stage of an outbreak, resulting in a bottleneck in which the infection may be vulnerable to medical treatment.

Degeneration of serotonergic neurons linked to spasticity in ALS

Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease with an occurrence rate in France similar to multiple sclerosis (two to three new cases per year for every 100,000 residents). It has a specific affect on neurons responsible for motor control, in particular motor neurones and central motor neurones. The former, located in the spinal cord, are directly linked to muscles and are used for muscle contraction and stretching.
