Prolonged electrical stimulation causes no damage to sacral nerve roots in rabbits

Prolonged electrical stimulation causes no damage to sacral nerve roots in rabbits
2014-07-29
(Press-News.org) Previous studies have shown that, anode block electrical stimulation of the sacral nerve root can produce physiological urination and reconstruct urinary bladder function in rabbits. However, whether long-term anode block electrical stimulation causes damage to the sacral nerve root remains unclear, and needs further investigation. In a recent study reported on the Neural Regeneration Research (Vol. 9, No. 12, 2014), Dr. Peng Yan and co-workers from Jilin University, China established a complete spinal cord injury model in New Zealand white rabbits through T9-10 segment transaction, and these model rabbits were given continuous electrical stimulation for a short period and then chronic stimulation for a longer period. Results showed that compared with normal rabbits, the structure of nerve cells in the anterior sacral nerve roots was unchanged in spinal cord injury rabbits after electrical stimulation. There was no significant difference in the expression of apoptosis-related proteins such as Bax, Caspase-3, and Bcl-2. Experimental findings indicate that neurons in the rabbit sacral nerve roots tolerate electrical stimulation, even after long-term anode block electrical stimulation.

Evolution in rainforest flies points to climate change survival

2014-07-29
Scientists believe some tropical species may be able to evolve and adapt to the effects of climate change. The new findings published in the journal, Proceedings of the Royal Society B, suggests some sensitive rainforest-restricted species may survive climate change and avoid extinction. But only if the change is not too abrupt and dramatically beyond the conditions that a species currently experiences. Previous research offered a bleak prospect for tropical species' adaptation to climate change, now researchers from Monash University believe the situation may not be ...

Vaccine website could increase uptake

2014-07-29
Giving parents access to a dedicated website on the measles, mumps and rubella (MMR) vaccine is the most cost-effective way to increase uptake, say experts. The study published in the British Journal of General Practice, recommends that a dedicated website be developed as part of guidelines on the MMR vaccine. Led by Dr Swati Shourie from Monash University and Dr Sandy Tubeuf from the University of Leeds in the UK, the research is the first to look at the economics of providing information about the MMR vaccine. As well as reducing parents' concern about immunising ...

Microscopic rowing -- without a cox

Microscopic rowing -- without a cox
2014-07-29
Many different types of cell, including sperm, bacteria and algae, propel themselves using whip-like appendages known as flagella. These protrusions, about one-hundredth of a millimetre long, function like tiny oars, helping cells move through fluid. Similar, shorter structures called cilia are found on the surfaces of many cells, where they perform roles such as moving liquids over the cell. Flagella and cilia are remarkably versatile: they transport mucus and expel pathogens from our airways, they establish the left-right asymmetry in developing vertebrate embryos, ...

Violent aftermath for the warriors at Alken Enge

Violent aftermath for the warriors at Alken Enge
2014-07-29
Denmark attracted international attention in 2012 when archaeological excavations revealed the bones of an entire army, whose warriors had been thrown into the bogs near the Alken Enge wetlands in East Jutland after losing a major engagement in the era around the birth of Christ. Work has continued in the area since then and archaeologists and experts from Aarhus University, Skanderborg Museum and Moesgaard Museum have now made sensational new findings. "We have found a wooden stick bearing the pelvic bones of four different men. In addition, we have unearthed bundles ...

New method provides researchers with efficient tool for tagging proteins

2014-07-29
Aarhus University researchers have developed an easier method to create DNA–protein conjugates. The method can potentially strengthen the work involved in diagnosing diseases. DNA linked to proteins – including antibodies – provides a strong partnership that can be used in diagnostic techniques, nanotechnology and other disciplines. DNA–protein conjugates – which tag proteins with DNA – can be used for purposes such as the sensitive detection and visualisation of biological material. The method also provides easier access to handling proteins in nanotechnology, where ...

New gadget helps the vision-impaired to read graphs

2014-07-29
People who are blind can now read more than just words, such as graphs and graphics, following the development of an affordable digital reading system by Curtin University researchers. Opening up new career paths and educational opportunities for people with vision impairment, the system combines a number of pattern recognition technologies into a single platform and, for the first time, allows mathematics and graphical material to be extracted and described without sighted intervention. Senior Lecturer Dr Iain Murray and PhD student Azadeh Nazemi of Curtin's Department ...

Congenital heart disease specialists develop nonsurgical technique to correct birth defects

2014-07-29
LOS ANGELES (July 28, 2014) – A new technique for repairing the most common cardiac birth defect in newborns, commonly referred to as "a hole in the heart," has been used successfully to mend the condition in six premature infants without subjecting the tiny patients to open-heart surgery. The technique for repairing the condition, patent ductus arteriosus, also called PDA, was published online by the peer-reviewed medical journal Catheterization and Cardiovascular Interventions, the official journal of The Society for Cardiovascular Angiography and Interventions. The ...

Researchers uncover secrets of internal cell fine-tuning

2014-07-29
New research from scientists at the University of Kent has shown for the first time how the structures inside cells are regulated – a breakthrough that could have a major impact on cancer therapy development. A team from Kent's School of Biosciences uncovered the mechanism whereby the physical properties of the internal structures within cells – known as actin filaments – are 'fine-tuned' to undertake different functions. While some of these actin filaments appear to completely stable, providing a framework for the cell, others are more dynamic, allowing the cell to ...

Determine patient preferences by means of conjoint analysis

2014-07-29
The Conjoint Analysis (CA) method is in principle suitable to find out which preferences patients have regarding treatment goals. However, to widely use it in health economic evaluations, some (primarily methodological) issues still need to be clarified. This is the result of a pilot project by the German Institute for Quality and Efficiency in Health Care (IQWiG). Following the Analytic Hierarchy Process (AHP), CA is the second method tested by the Institute together with external experts. Summarize outcome-specific results to an overall value In its health economic ...

Healthy lifestyle may buffer against stress-related cell aging, study says

2014-07-29
A new study from UC San Francisco is the first to show that while the impact of life's stressors accumulate overtime and accelerate cellular aging, these negative effects may be reduced by maintaining a healthy diet, exercising and sleeping well. "The study participants who exercised, slept well and ate well had less telomere shortening than the ones who didn't maintain healthy lifestyles, even when they had similar levels of stress," said lead author Eli Puterman, PhD, assistant professor in the department of psychiatry at UCSF. "It's very important that we promote ...
