New rapid laboratory test successful in identifying GBS colonization in pregnant women

A more rapid laboratory test for pregnant women to detect potentially deadly Group B strep (GBS) has been successful at identifying GBS colonization in six and a half hours, according to the results of a study from The University of Texas Health Science Center at Houston (UTHealth).

Medication use and doctor visits drive up jaw necrosis-related costs

Long-term medication use and follow-up visits are the main drivers affecting costs associated with cancer-related bisphosphonate-associated osteonecrosis of the jaw, report researchers in Oral Diseases.

Researchers uncover cellular-level detail of what happens when bone bears stress over time

From athletes to individuals suffering from osteoporosis, bone fractures are usually the result of tiny cracks accumulating over time -- invisible rivulets of damage that, when coalesced, lead to that painful break.

Weill Cornell receives NIMH grant to discover novel biomarkers for chronic fatigue syndrome

Weill Cornell Medical College has been awarded more than $1.9 million by the National Institute of Mental Health of the National Institutes of Health to lead an innovative research study using advanced neuroimaging and clinical evaluations of patients with chronic fatigue syndrome (CFS).

Chronic obstructive pulmonary disease (COPD) inflammatory subtypes: an interview with Dr Vanessa McDonald, University of Newcastle, Australia

COPD is defined as a preventable and treatable disease associated with significant extrapulmonary consequences that may contribute to severity. The pulmonary component of COPD is characterised by airflow limitation that is not fully reversible. The airflow limitation is usually progressive with an abnormal inflammatory response of the lungs to noxious particles (GOLD Strategy Document). Airflow obstruction in COPD is not highly variable and largely irreversible.

Researchers discover ovarian stem-like epithelial cells that can mutate to form tumors

In collaboration with colleagues at Cornell University, a team of cancer researchers at Cold Spring Harbor Laboratory (CSHL) has discovered cells with stem-cell properties in the ovary that can mutate to form tumors.

Melittin-loaded nanoparticles can destroy human immunodeficiency virus

Nanoparticles carrying a toxin found in bee venom can destroy human immunodeficiency virus (HIV) while leaving surrounding cells unharmed, researchers at Washington University School of Medicine in St. Louis have shown.

Southeast Asia's commercial trade plays a central role in spread of amphibian pathogens

A team of scientists led by the Wildlife Conservation Society (WCS) and the National University of Singapore (NUS), revealed in a new study, for the first time, the presence of the pathogenic chytrid fungus (Batrachochytrium dendrobatidis) in amphibians sampled in Singapore. And the American bullfrog may be a central player in the spread of the disease.

SRSF1 protein can prevent cancerous proliferation by stabilizing p53

Some cellular proteins have multiple, and occasionally opposing, functions. Professor Adrian Krainer and colleagues at Cold Spring Harbor Laboratory demonstrate in a paper published online today in Molecular Cell that the oncogenic protein SRSF1 can also trigger a stop in cell growth and prevent cancerous proliferation by stabilizing p53, the powerful tumor-suppressor protein.

Rats sniff each other to signal a social hierarchy and prevent aggressive behavior

Sniffing, a common behavior in dogs, cats and other animals, has been observed to also serve as a method for rats to communicate-a fundamental discovery that may help scientists identify brain regions critical for interpreting communications cues and what brain malfunctions may cause some complex social disorders.

Salk epigenetic findings may aid in crop production and study of human diseases

Scientists at the Salk Institute for Biological Studies have identified patterns of epigenomic diversity that not only allow plants to adapt to various environments, but could also benefit crop production and the study of human diseases.

Analysis of anonymized web log data on drugs could be used as early warning system

The authors base their findings on an analysis of the anonymised search logs of millions of US web users, who agreed to install a browser add-on and share their online searches with Microsoft throughout 2010.

Genomic analysis could illuminate more options in developing precise treatments for cancer

Investigators working on the precision medicine initiative at The Cancer Institute of New Jersey are embarking on a genomic analysis study which could illuminate more options in developing personalized and precise treatments for cancer patients.

Study reveals increased dietary salt intake may lead to autoimmune disorders

Increased dietary salt intake can induce a group of aggressive immune cells that are involved in triggering and sustaining autoimmune diseases.

UCLA scientists discover new genetic risk factor for Alzheimer's disease

Scientists at UCLA have discovered a new genetic risk factor for Alzheimer's disease by screening people's DNA and then using an advanced type of scan to visualize their brains' connections.

Parietal brain cells sort visual information into categories: Study

A region of the brain known to play a key role in visual and spatial processing has a parallel function: sorting visual information into categories, according to a new study by researchers at the University of Chicago.

High HDL levels block development of aneurysms in the aorta

New research provides early evidence that 'good' cholesterol may possess anti-aneurysm forming properties. In laboratory-based investigations, scientists found that increased levels of high-density lipoproteins (HDL), the so-called good cholesterol, blocked the development of aneurysms - dangerous 'ballooning' in the wall of a blood vessel - in the body's largest artery, the aorta.
