Polysaccharides from Angelica sinensis alleviate oxidative damage to neurons

Polysaccharides from Angelica sinensis alleviate oxidative damage to neurons
2014-04-09
(Press-News.org) According to traditional Chinese medicine, the roles of Angelica sinensis correlate with tonifying the blood and promoting its circulation. Recent studies have shown that extracts of Angelica sinensis have antioxidative and neuroprotective effects. However, the anti-oxidative function of Angelica sinensis polysaccharide has rarely been addressed. In a preliminary experiment from Dr. Tao Lei and colleagues from Zhongnan Hospital of Wuhan University in China, Angelica sinensis polysaccharides not only protected PC12 neuronal cells from H2O2-induced cytotoxicity, but also reduced apoptosis and intracellular reactive oxygen species levels, and increased the mitochondrial membrane potential induced by H2O2 treatment. In a rat model of local cerebral ischemia, they further demonstrated that Angelica sinensis polysaccharides enhanced the antioxidant activity in cerebral cortical neurons, increased the number of microvessels, and improved blood flow after ischemia. Their findings, published in the Neural Regeneration Research (Vol. 9, No. 3, 2014), highlight the protective role of polysaccharides isolated from Angelica sinensis against nerve cell injury and impairment caused by oxidative stress.

Stressful environments genetically affect African American boys

Stressful environments genetically affect African American boys
2014-04-09
PRINCETON, N.J.—Stressful upbringings can leave imprints on the genes of children as young as age 9, according to a study led by Princeton University and Pennsylvania State University researchers. Such chronic stress during youth leads to physiological weathering similar to aging. A study of 40 9-year-old black boys, published in the Proceedings of the National Academy of Sciences, shows that those who grow up in disadvantaged environments have shorter telomeres — DNA sequences that generally shrink with age — than their advantaged peers. The researchers also report ...

Unity is strength in the marketing of smallholder farm produce

2014-04-09
Smallholder farmers often face the challenge of accessing markets and selling their produce at competitive prices because they produce in small quantities that may not be commercially viable. The farmers are now being advised to adopt market interventions such as 'collective action' where they can come together as a group to pool their harvests and sell it in bulk. A study conducted by the World Agroforesty Centre (ICRAF) in Cameroon has shown that effective implementation of collective action improves market access for smallholder producers of agroforestry products ...

Is the increased risk of death due to alcohol intake greater for women or men?

Is the increased risk of death due to alcohol intake greater for women or men?
2014-04-09
New Rochelle, NY, April 9, 2014—The increased risk of death associated with alcohol intake is not the same for men and women. A study that compared the amount of alcohol consumed and death from all causes among nearly 2.5 million women and men showed that the differences between the sexes became greater as alcohol intake increased, as described in an article in Journal of Women's Health, a peer-reviewed publication from Mary Ann Liebert, Inc., publishers. The article is available free on the Journal of Women's Health website at http://www.liebertpub.com/jwh. In the article ...

Toward a faster, more accurate way to diagnose stroke

2014-04-09
When someone suffers from a stroke, a silent countdown begins. A fast diagnosis and treatment can mean the difference between life and death. So scientists are working on a new blood test that one day could rapidly confirm whether someone is having a stroke and what kind. Their report appears in the ACS journal Analytical Chemistry. Steven A. Soper and colleagues note that strokes, which are the third leading cause of death and disability in the United States, have two possible causes. In ischemic strokes, a clot stops blood flow in a part of the brain. In hemorrhagic ...

Tiny step edges, big step for surface science

Tiny step edges, big step for surface science
2014-04-09
This news release is available in French. It can be found in toothpaste, solar cells, and it is useful for chemical catalysts: titanium dioxide (TiO2) is an extremely versatile material. Alhough it is used for so many different applications, the behaviour of titanium oxide surfaces still surprises. Professor Ulrike Diebold and her team at the Vienna University of Technology managed to find out why oxygen atoms attach so well to tiny step edges at titanium oxide surfaces. Electrons accumulate precisely at these edges, allowing the oxygen atoms to connect more strongly. ...

660 nm red light-enhanced BMSCs transplantation for hypoxic-ischemic brain damage

660 nm red light-enhanced BMSCs transplantation for hypoxic-ischemic brain damage
2014-04-09
A series of previous studies suggested that the neuronal differentiation rate of bone marrow mesenchymal stem cells during the in vitro culture reached 78-92%, but their in vivo transplantation efficiency, and survival and differentiation rates were very low. The low levels of bone marrow mesenchymal stem cell transplantation, survival, colonization and differentiation efficacy greatly restrict their therapeutic effect. Red or near-infrared light from 600-1,000 nm promotes cellular migration and prevents apoptosis. Thus, Dr. Xiaoying Wu and co-workers from Chongqing University ...

Dabrafenib: Also no added benefit over vemurafenib

2014-04-09
Dabrafenib (trade name: Tafinlar) has been approved since August 2013 for the treatment of advanced melanoma. In January 2014, in an early benefit assessment pursuant to the "Act on the Reform of the Market for Medicinal Products" (AMNOG), the German Institute for Quality and Efficiency in Health Care (IQWiG) had determined that dabrafenib has no added benefit in comparison with dacarbazine. IQWiG now assessed dabrafenib in comparison with vemurafenib. The report presented in the form of an addendum came to the same conclusion because the results from the indirect comparison ...

ORNL study pegs fuel economy costs of common practices

2014-04-09
OAK RIDGE, Tenn., April 9, 2014 – People who pack their cars and drive like Clark Griswold in National Lampoon's "Vacation" pay a steep penalty when it comes to fuel economy, according to a report by the Department of Energy's Oak Ridge National Laboratory. For the study, researchers tested a sport utility vehicle and a compact sedan with various configurations, including underinflated tires, open windows, and rooftop and hitch-mounted cargo. The SUV, a 2009 Ford Explorer with a 4-liter V6 engine, was also tested while towing an enclosed trailer. The researchers tested ...

Love is a many-faceted thing

2014-04-09
Regular churchgoers, married people or those who enjoy harmonious social ties are most satisfied with their love life. This also goes for people who are currently in love or who experience the commitment and sexual desire of their partners, says Félix Neto and Maria da Conceição Pinto of the Universidade do Porto in Portugal. Their findings, published in an article in Springer's journal Applied Research in Quality of Life, look at the influences on love life satisfaction throughout one's adult life. The researchers associate love with the desire to enter into, maintain, ...

BU researchers identify specific causes of brown fat cell 'whitening'

2014-04-09
(Boston) – Boston University researchers have learned new information about the consequences of overeating high-calorie foods. Not only does this lead to an increase in white fat cell production, the type prominent in obesity, but it also leads to the dysfunction of brown fat cells, the unique type of fat that generates heat and burns energy. This study is the first to describe how overeating causes brown fat cells to "whiten." Published in the Journal of Clinical Investigation, the results illustrate the important role that a healthy diet plays in overall health and ...
