Targeting inflammatory pathway reduces Alzheimer's disease in mice

2014-12-16
(Press-News.org) Alzheimer's disease (AD) is the most common form of dementia and is characterized by the formation of β-amyloid plaques throughout the brain. Proteins known as chemokines regulate inflammation and the immune response. In both patients with AD and mouse AD models, the chemokine CXCL10 is found in high concentrations in the brain and may contribute to AD. A new study in the Journal of Clinical Investigation indicates that activation of the CXCL10 receptor, CXCR3, contributes to AD pathology. Using a murine model of AD, Michael Heneka and colleagues at the University of Bonn found that mice lacking CXCR3 had reduced β-amyloid plaque formation. Importantly, loss of CXCR3 signaling in AD mice attenuated behavioral deficits. The results of this study suggest that CXCR3 should be explored as a potential therapeutic target for AD.

Microbial-induced pathway promotes nonalcoholic fatty liver disease

2014-12-16
Nonalcoholic fatty liver disease (NAFLD) is the most common liver disorder and affects approximately 1 billion people worldwide. It is not clear how this disease develops, but recent studies suggest that the bacterial population in the gut influences NAFLD. A new study in the Journal of Clinical Investigation provides a link between molecular signaling pathways in the gut, the intestinal microbiome, and development of NAFLD. Frank Gonzalez and colleagues at the National Cancer Institute found that disruption of the gut microflora prevented development of NAFLD in mice fed ...

How to treat Ebola during pregnancy

2014-12-15
A pregnant woman in Africa who has contracted Ebola is likely to suffer with a spontaneous abortion, pregnancy-related hemorrhage, or the death of her newborn. Although the risk of caring for a pregnant woman with Ebola in the United States may be rare, the Association of Women's Health, Obstetric and Neonatal Nurses (AWHONN) has published a practice brief in its Journal of Obstetric, Gynecologic, & Neonatal Nursing to guide nursing care for pregnant women and newborns. "Nurses play a vital role in caring for patients with Ebola," said Dr. Debra Bingham, who is Vice President ...

Shame on us

Shame on us
2014-12-15
Emotions are complicated and never more so than in the realm of the scientific, where commonly accepted definitions are lacking. In a paper published in the journal Qualitative Inquiry, UC Santa Barbara's Thomas Scheff examines the basic emotions of grief, fear/anxiety, anger, shame and pride as they appear in scientific literature in an attempt to take a first step in defining them. "Emotion terms, especially in English, are wildly ambiguous," Scheff writes in the paper's introduction. An emeritus professor of sociology at UCSB, Scheff set out to explore why the language ...

Herceptin found to improve long-term survival of HER2-positive breast cancer patients

2014-12-15
VCU Massey Cancer Center physician-researcher Charles E. Geyer, Jr., M.D., was the National Protocol Officer for one component of a large national study involving two National Cancer Institute (NCI)-supported clinical trials that demonstrated that trastuzumab significantly improves the long-term survival of HER-2 positive breast cancer patients. The combined study was designed to determine the long-term safety and efficacy of the drug trastuzumab, which is commonly known as Herceptin and is primarily used alongside chemotherapy to treat HER2-positive breast cancer. The ...

Switching to vehicles powered by electricity from renewables could save lives

2014-12-15
Driving vehicles that use electricity from renewable energy instead of gasoline could reduce the resulting deaths due to air pollution by 70 percent. This finding comes from a new life cycle analysis of conventional and alternative vehicles and their air pollution-related public health impacts, published Monday, Dec. 15, 2014, in the Proceedings of the National Academy of Sciences. The study also shows that switching to vehicles powered by electricity made using natural gas yields large health benefits. Conversely, vehicles running on corn ethanol or vehicles powered ...

Non-Gluten proteins identified as targets of immune response to wheat in celiac disease

2014-12-15
NEW YORK, NY (December 15, 2014)--Researchers at Columbia University Medical Center have found that, in addition to gluten, the immune systems of patients with celiac disease react to specific types of non-gluten protein in wheat. The results were reported online in the Journal of Proteome Research. Celiac disease, an autoimmune disorder that affects about 1 percent of the U.S. population, is triggered by the ingestion of wheat and related cereals in genetically susceptible individuals. The immune response results in inflammation and tissue damage in the small intestine, ...

Chapman University research on farmers' markets shows presence of Salmonella and E. coli

2014-12-15
ORANGE, Calif. - Researchers in Chapman University's Food Science Program and their collaborators at University of Washington have just published a study on the presence of Salmonella and E. coli on certain herbs sold at farmers' markets. The study focused on farmers' markets in Los Angeles and Orange counties in California, as well as in the Seattle, Washington, area. Specifically tested were samples of the herbs cilantro, basil and parsley. Of the 133 samples tested from 13 farmers' markets, 24.1 percent tested positive for E. coli and one sample tested positive for Salmonella. "While ...

Dartmouth researchers create 'green' process to reduce molecular switching waste

Dartmouth researchers create green process to reduce molecular switching waste
2014-12-15
HANOVER, N.H. - Dartmouth researchers have found a solution using visible light to reduce waste produced in chemically activated molecular switches, opening the way for industrial applications of nanotechnology ranging from anti-cancer drug delivery to LCD displays and molecular motors. The study appears in the Journal of the American Chemical Society. A PDF is available on request. Chemically activated molecular switches are molecules that can shift controllably between two stable states and that can be reversibly switched -- like a light switch -- to turn different ...

Seeing the forest for the trees

Seeing the forest for the trees
2014-12-15
The largest trees in a forest may command the most attention, but the smallest seedlings and youngest saplings are the ones that are most critical to the composition and diversity of the forest overall. While many people gaze up into the forest canopy, renowned scientist Joseph Connell has spent much of his career looking down quite closely at the forest understory. Connell, who is a professor emeritus in the Department of Ecology, Evolution and Marine Biology at the University of California at Santa Barbara, established one of the world's longest, in-depth ecological research ...
