(Press-News.org) Researchers at Central Taiwan University of Science and Technology, Taiwan, led by Prof. Liu, Dr. Shen and Mrs. Yang have developed a biodegradable nerve conduit containing genipin-cross-linked gelatin was annexed using beta-tricalcium phosphate (TCP) ceramic particles (Genipin-Gelatin-TCP, GGT) to bridge the transection of a 15 mm sciatic nerve in rats. The effects of LLL therapy on peripheral nerve restoration and regeneration have systematically investigated throughout the study period.
Very few studies have employed tubulation in combination with diode laser therapy to repair nerve lesions. Furthermore, very few researchers have investigated the influence of LLL therapy on neural regeneration in a biodegradable nerve conduit.
The study, reported on Neural Regeneration Research (Vol. 9, No.12, 2014), confirmed that combining the GGT nerve conduit with an LLL therapy system may be beneficial for the regeneration of nerves across long gaps, as well as for accelerating the reinnervation rate of nerves and improving recruitment in muscles. These benefits may in turn lead to improve functional and morphologic recovery of peripheral nerves. Further studies on the use of LLL therapy as a noninvasive treatment modality for various nerve diseases and injuries could pave the way for mainstream acceptance and standardization of this innovative therapy.

Researchers find mechanism that clears excess of protein linked with Type 2 diabetes
2014-07-24
The cellular process autophagy appears to not work properly, contributing to the destruction of insulin-producing beta cells
People with Type 2 diabetes have an excess of a protein called islet amyloid polypeptide, or IAPP, and the accumulation of this protein is linked to the loss of insulin-producing pancreatic beta cells.
What causes this accumulation of IAPP in pancreatic beta cells of people with diabetes has remained a mystery. But a team of researchers from the Larry L. Hillblom Islet Research Center led by Dr. Peter Butler, professor of medicine at UCLA, may ...
Astronomers come up dry in search for water on exoplanets
2014-07-24
TORONTO, ON (23 JULY 2014) – A team of astronomers has made the most precise measurements yet of water vapour in the atmospheres of Jupiter-like planets beyond our Solar System and found them to be much drier worlds than expected.
The team, including Dr. Nicolas Crouzet of the Dunlap Institute for Astronomy & Astrophysics, University of Toronto, has found that the abundance of atmospheric water vapour is between ten and a thousand times less than what models predict.
"The low water vapour levels are surprising," says Crouzet. "Our models predict a much higher abundance ...
One route to malaria drug resistance found
2014-07-24
Researchers have uncovered a way the malaria parasite becomes resistant to an investigational drug. The discovery, at Washington University School of Medicine in St. Louis, also is relevant for other infectious diseases including bacterial infections and tuberculosis.
The study appears July 24 in Nature Communications.
Many organisms, including the parasite that causes malaria, make a class of molecules called isoprenoids, which play multiple roles in keeping organisms healthy, whether plants, animals or bacteria. In malaria, the investigational drug fosmidomycin blocks ...
New methods of detecting Salmonella in pork meat processing
2014-07-24
Traditional methods of characterising and detecting bacteria are often slow and time-consuming. Therefore, development of new methods of characterising and detecting illness-causing microorganisms is very important for improving food safety.
Trine Hansen, PhD student at the National Food Institute, has studied new methods of characterising Salmonella in pork meat processing and detecting unknown bacteria in water, feed and food samples.
The research project has given a better understanding of which factors in pork meat processing may contribute to the development of ...
Chemist develops X-ray vision for quality assurance
2014-07-24
It is seldom sufficient to read the declaration of contents if you need to know precisely what substances a product contains. In fact, to do this you need to be a highly skilled chemist or to have genuine X-ray vision so that you can look directly into the molecular structure of the various substances. Christian Grundahl Frankær, a Postdoc at DTU Chemical Engineering, is almost both, as he has developed a method that allows him to use X-rays to look deep into biological samples.
The 'Fingerprints' of a Substance
The technique is called 'powder diffraction' and involves ...
Unleashing the power of quantum dot triplets
2014-07-24
Quantum computers have yet to materialise. Yet, scientists are making progress in devising suitable means of making such computers faster. One such approach relies on quantum dots—a kind of artificial atom, easily controlled by applying an electric field. A new study demonstrates that changing the coupling of three coherently coupled quantum dots (TQDs) with electrical impulses can help better control them. This has implications, for example, should TQDs be used as quantum information units, which would produce faster quantum computers due to the fact that they would be ...
Tempting people to move for work takes more than dollars
2014-07-24
Sufficient financial inducements are one way of encouraging people to move to regional Australia for jobs, but other factors also play a part, according to a new report.
Moving workers from a region with high unemployment to a region with many job vacancies is an important aspect of labour markets. The Commission of Audit recently advised the government to "force" long-term unemployed people who are single and between the ages of 22 and 30 to move to areas of higher employment if they have been on the dole for 12 months.

Study reveals medical students believe health policy education is improving
2014-07-24
Philadelphia – Students graduating from U.S. medical schools in 2012 feel they've received a better education in health policy issues than graduates surveyed in 2008, according to a multi-center study led by the Perelman School of Medicine at the University of Pennsylvania, and published online this month in Academic Medicine. The study applied a new framework for teaching and evaluating perceptions of training in health policy, first proposed by the authors in a 2011 perspective published in the New England Journal of Medicine.

Discovery is key to metal wear in sliding parts
2014-07-24
WEST LAFAYETTE, Ind. – Researchers have discovered a previously unknown mechanism for wear in metals: a swirling, fluid-like microscopic behavior in a solid piece of metal sliding over another.
The findings could be used to improve the durability of metal parts in numerous applications.
"Wear is a major cause of failure in engineering applications," said Srinivasan Chandrasekar, a Purdue University professor of industrial engineering and materials engineering. "However, our findings have implications beyond wear itself, extending to manufacturing and materials processing."
The ...
Highest-precision measurement of water in planet outside the solar system
2014-07-24
A team of astronomers using NASA's Hubble Space Telescope have gone looking for water vapour in the atmospheres of three planets orbiting stars similar to the Sun – and have come up nearly dry.
The three planets, HD 189733b, HD 209458b, and WASP-12b, are between 60 and 900 light-years away, and are all gas giants known as 'hot Jupiters.' These worlds are so hot, with temperatures between 900 to 2200 degrees Celsius, that they are ideal candidates for detecting water vapour in their atmospheres.
However, the three planets have only one-tenth to one-thousandth the ...
