Caltech biologists identify mechanism by which beneficial bacteria reside, thrive in gastrointestinal tract

The human body is full of tiny microorganisms-hundreds to thousands of species of bacteria collectively called the microbiome, which are believed to contribute to a healthy existence. The gastrointestinal (GI) tract-and the colon in particular-is home to the largest concentration and highest diversity of bacterial species.

Copper enhances progression of Alzheimer's disease

Copper appears to be one of the main environmental factors that trigger the onset and enhance the progression of Alzheimer's disease by preventing the clearance and accelerating the accumulation of toxic proteins in the brain. That is the conclusion of a study appearing today in the journal Proceedings of the National Academy of Sciences.

IBN researchers one step closer to viable tissue replacements

Researchers at the Institute of Bioengineering and Nanotechnology have developed a simple method of organizing cells and their microenvironments in hydrogel fibers. Their unique technology provides a feasible template for assembling complex structures, such as liver and fat tissues, as described in their recent publication in Nature Communications.

Powerful mechanism helps viruses evade body's immune response

Researchers at the Salk Institute for Biological Studies have discovered a powerful mechanism by which viruses such as influenza, West Nile and Dengue evade the body's immune response and infect humans with these potentially deadly diseases. The findings may provide scientists with an attractive target for novel antiviral therapies.

Interactions between sympathetic neurons and pancreatic cells have implications for organ development

The human body is a complicated system of blood vessels, nerves, organs, tissue and cells each with a specific job to do. When all are working together, it's a symphony of form and function as each instrument plays its intended roles.

Calcium and vitamin D supplements have no effect on joint symptoms in postmenopausal women

A team of investigators systematically analyzed the effect of calcium and vitamin D supplementation on joint symptoms in a rigorous and controlled study of postmenopausal women. They found that supplementation did not reduce the severity of joint symptoms reported by the participants.

Scientists identify new therapeutic targets to inhibit progression of Alzheimer's disease

To stop the progression of Alzheimer's disease in the early stage, it is necessary to identify new therapeutic targets. Prof. Yunpeng Cao and team from the First Affiliated Hospital of China Medical University examined striatal-enriched phosphatase 61 expression in the brain tissues of Alzheimer's disease rats using in vivo and in vitro models, and analyzed the molecular mechanism by which striatal-enriched phosphatase 61 regulates N-methyl-D- aspartate receptor 2B transport.

Researchers study demographic, socioeconomic factors that buffer effects of video game violence

In November 2010, an online gaming company called ActiVision released Call of Duty: Black Ops, a violent, first-person shooter game compatible with a variety of gaming devices. The video game sold 5.6 million copies within 24 hours of its release, and it earned a record-breaking $650 million in its first five days. Six weeks later, the game had exceeded $1 billion in sales.

Increased caffeine intake may reduce fatty liver in people with NAFLD

Surprise! Your morning cup of tea or coffee may be doing more than just perking you up before work. An international team of researchers led by Duke-NUS Graduate Medical School (Duke-NUS) and the Duke University School of Medicine suggest that increased caffeine intake may reduce fatty liver in people with non-alcoholic fatty liver disease (NAFLD).

Study shows lymph node location influences maturation process of cells they contain

Based on their observations, the scientists deduced that lymph node location influences the maturation process of the cells they contain. "The cells retained their original skills for weeks following the transplant," says Dr. Sascha Cording, one of the study's first authors. "You might say lymph nodes have something like a location-specific memory."

Michigan researchers use TACC supercomputers to understand DNA bending, repair mechanisms

The biological information that makes us unique is encoded in our DNA. DNA damage is a natural biological occurrence that happens every time cells divide and multiply. External factors such as overexposure to sunlight can also damage DNA.

BIDMC cardiovascular research team receives $4M grant to identify mRNA biomarkers in heart disease

A cardiovascular research team from Beth Israel Deaconess Medical Center (BIDMC) and Brigham and Women's Hospital (BWH), led by BIDMC Principal Investigator Saumya Das, MD, PhD, has been awarded a $4 million Common Fund grant from the National Institutes of Health (NIH) as part of a newly formed program on Extracellular RNA Communication.

Prion proteins responsible for Mad cow disease, Creutzfeld-Jakob disease

Mad cow disease and its cousin Creutzfeld-Jakob disease cause fatal spongy changes in brain tissue. Today, we know that these diseases are caused by prions, proteins that are folded incorrectly. A team of German researchers have now been able to follow how the diseased proteins aggregate and "infect" healthy ones on the atomic scale. Their report appears in the journal Angewandte Chemie.
