Novel methods may help stem cells survive transplantation into damaged tissues

Novel methods may help stem cells survive transplantation into damaged tissues
2014-07-22
(Press-News.org) New Rochelle, NY -- Stem cells offer much promise for treating damaged organs and tissues, but with current transplantation approaches stem cell survival is poor, limiting their effectiveness. New methods are being developed and tested to improve the survival and optimize their therapeutic function after transplantation, as described in a Review article in BioResearch Open Access, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers. The article is available free on the BioResearch Open Access website.

In the article 'Preconditioning Stem Cells for In Vivo Delivery,' Sébastien Sart, Ecole Polytechnique (Palaiseau, France) and Teng Ma and Yan Li, Florida State University (Tallahassee) examine the leading strategies for preconditioning stem cells prior to transplantation to prepare them for the environment often found in damaged tissue. Preconditioning methods might include exposing stem cells to microenvironments characterized by reduced oxygen levels, heat shock, and oxidative stress, creating three-dimensional stem cell aggregates or microtissues, and using hydrogels in which to embed or encapsulate the cells.

"This article provides an extensive review of the current methods of stem cell preconditioning for transplantation," says BioResearch Open Access Editor Jane Taylor, PhD, MRC Centre for Regenerative Medicine, University of Edinburgh, Scotland. "It also highlights the cutting edge technologies employed to do this."

Study compares cost-effectiveness of weight-loss programs and drugs

2014-07-22
DURHAM, N.C. – In a cost-effectiveness analysis of commercial diet programs and pills, the Weight Watchers program and the drug Qsymia showed the best value for the money. The Jenny Craig regimen generated the greatest weight loss, but was also the most expensive option tested, according to researchers at Duke-National University of Singapore (NUS) Graduate Medical School. The findings, published in the June issue of the journal Obesity, provide important information on the health and weight-loss benefits per dollar spent as insurance carriers consider coverage for weight ...

The nostalgia effect: Do consumers spend more when thinking about the past?

2014-07-22
Say you are out clothes shopping and you spot something that brings you back to a special time from your childhood when you were surrounded by friends and family. Suddenly, you find yourself purchasing an expensive shirt that makes you feel like a kid again. According to a new study in the Journal of Consumer Research, we're more likely to spend money when we're feeling nostalgic. "We wondered why nostalgia is so commonplace in marketing. One reason could be that feeling nostalgic weakens a person's desire for money. In other words, someone might be more likely to buy ...

Trying to get kids to eat healthier? Don't tell them veggies are good for them

2014-07-22
At some point, most kids will hear that drinking milk helps make their bones strong or that fish is food for the brain. But do these messages foster the idea that if something is good for us, it must surely taste bad? According to a new study in the Journal of Consumer Research, when children hear about the benefits of healthy food, they're less likely to eat it. "We predicted that when food is presented to children as making them strong or as a tool to achieve a goal such as learning how to read or count, they would conclude the food is not as tasty and therefore consume ...

You deserve it! Are consumers more likely to buy unique products when made to feel special?

2014-07-22
Graduating from college is an important life event often attributed to being smart and working hard. Many people celebrate this milestone achievement by buying themselves an expensive gift or taking a dream vacation. A new study in the Journal of Consumer Research shows that consumers who attribute their successes to internal character traits rather than hard work are more likely to select unique products. "We found that consumers who attribute feelings of pride to their unique character traits—rather than how hard they worked to accomplish something—are more likely to ...

HIF 1α viral vector inhibits hippocampal neuronal apoptosis: The future of gene therapy

HIF 1α viral vector inhibits hippocampal neuronal apoptosis: The future of gene therapy
2014-07-22
Hypoxia-inducible factor 1 (HIF-1) attenuates amyloid-beta protein neurotoxicity and decreases apoptosis induced by oxidative stress or hypoxia in cortical neurons. Prof. Xiqing Chai and co-workers from Hebei Chemical and Pharmaceutical College, China constructed a recombinant adeno-associated virus (rAAV) vector expressing the human HIF-1α gene (rAAV-HIF-1α) efficiently, and tested the assumption that rAAV-HIF-1α represses hippocampal neuronal apoptosis induced by amyloid-beta protein. Their results confirmed that rAAV-HIF-1α significantly reduces apoptosis ...

Acupuncture at the Taixi activates cerebral neurons in old patients with MCI

2014-07-22
Previous findings have demonstrated that acupuncture at the Taixi (KI3) acupoint in healthy youths can activate neurons in cognitive-related cerebral cortex. In a perspective article released in the Neural Regeneration Research (Vol. 9, No. 11, 2014), Dr. Shangjie Chen and co-workers at Baoan Hospital, Southern Medical University, China investigated whether acupuncture at this acupoint in elderly patients with mild cognitive impairment (MCI) can also activate neurons in these regions. Researchers revealed that under resting state and task-related functional magnetic resonance ...

X-ray irradiation at a certain dose alters the neuronal cytoskeleton and cytomechanics
2014-07-22
Cranial radiotherapy is one of the most important therapeutic methods for the treatment of various types of primary and metastatic brain tumors. Although conventional photon irradiation has significantly improved the treatment of cancer, the central nervous system is prone to damage after high-dose irradiation, resulting in severe delayed or progressive nervous tissue injury. The issues regarding brain radiation injury have been widely discussed, and recent investigations have emphasized changes in pathomorphology. However, the underlying mechanism remains in debate. Researchers ...

Self-cooling solar cells boost power, last longer

Self-cooling solar cells boost power, last longer
2014-07-22
WASHINGTON, July 22, 2014—Scientists may have overcome one of the major hurdles in developing high-efficiency, long-lasting solar cells—keeping them cool, even in the blistering heat of the noonday Sun. By adding a specially patterned layer of silica glass to the surface of ordinary solar cells, a team of researchers led by Shanhui Fan, an electrical engineering professor at Stanford University in California has found a way to let solar cells cool themselves by shepherding away unwanted thermal radiation. The researchers describe their innovative design in the premiere ...

Major dopamine system helps restore consciousness after general anesthesia, study finds

2014-07-22
Chicago – July 22, 2014 – Researchers may be one step closer to better understanding how anesthesia works. A study in the August issue of Anesthesiology, the official medical journal of the American Society of Anesthesiologists® (ASA®), found stimulating a major dopamine-producing region in the brain, the ventral tegmental area (VTA), caused rats to wake from general anesthesia, suggesting that this region plays a key role in restoring consciousness after general anesthesia. Activating this region at the end of surgery could provide a novel approach to proactively induce ...

Creating optical cables out of thin air
2014-07-22
Imagine being able to instantaneously run an optical cable or fiber to any point on earth, or even into space. That's what Howard Milchberg, professor of physics and electrical and computer engineering at the University of Maryland, wants to do. In a paper published today in the July 2014 issue of the journal Optica, Milchberg and his lab report using an "air waveguide" to enhance light signals collected from distant sources. These air waveguides could have many applications, including long-range laser communications, detecting pollution in the atmosphere, making high-resolution ...
