Researchers to develop 'wearable' robotic tools for surgery

Tue, 14/03/2017 - 1:32pm
A collaborative team of researchers is to develop a wearable robotic system for minimally invasive surgery, also known as keyhole surgery, that will offer surgeons natural and dexterous movement as well as the ability to ‘sense’, ‘see’, control and safely navigate through the surgical environment.

Epigenetic alteration a promising new drug target for heroin use disorder

Tue, 14/03/2017 - 1:31pm
The past few years have seen an explosion of heroin abuse and deaths from opiate overdose. But little is known about the molecular underpinnings of heroin addiction. A new study has found that heroin use is associated with excessive histone acetylation, an epigenetic process that regulates gene expression. More years of drug use correlated with higher levels of hyperacetylation. The study provides the first direct evidence of opiate-related epigenetic alterations in the human brain.

Zebrafish without stripes

Tue, 14/03/2017 - 1:30pm
Dowling-Degos disease is a hereditary pigmentation disorder that generally progresses harmlessly. However, some of those affected also develop severe skin inflammation. An international team of researchers has now found a cause for this link. Their knowledge comes thanks to an animal that is known among aquarium owners for its characteristic pigmentation: the zebrafish.

Ice age thermostat prevented extreme climate cooling

Tue, 14/03/2017 - 1:30pm
During the ice ages, an unidentified regulatory mechanism prevented atmospheric carbon dioxide concentrations from falling below a level that could have led to runaway cooling, reports a team of researchers. The study suggests the mechanism may have involved the biosphere, as plants and plankton struggled to grow under very low carbon dioxide levels.

Leisure-time physical activity is related to cartilage health and quality health in knee osteoarthritis

Tue, 14/03/2017 - 1:30pm
Higher leisure-time physical activity (LTPA) level promotes cartilage health in postmenopausal women with mild knee osteoarthritis (OA). This study investigated the relationship between 12-month LTPA level and changes in estimated biochemical composition in tibiofemoral cartilage.

Breathtaking gene discovery in Dalmatian dogs

Tue, 14/03/2017 - 1:27pm
A novel gene associated with acute respiratory distress syndrome (ARDS) in dogs has been uncovered by scientists. The new research on this fatal disease may also help us understand the mechanisms of respiratory diseases in humans.

VTT has developed stand-up pouches from renewable raw materials, nanocellulose

Tue, 14/03/2017 - 1:27pm
Lightweight 100% bio-based stand-up pouches have been developed with high technical performance. High performance in both oxygen, grease and mineral oil barrier properties has been reached by using different biobased coatings on paper substrate. The pouches exploit patent pending high consistency enzymatic fibrillation of cellulose (HefCel) technology.

Animal poisoners in native forests

Tue, 14/03/2017 - 1:27pm
The common oribatid mite species Oribatula tibialis is an extremely clever poisoner, as an interdisciplinary team of researchers has found. The mite uses hydrogen cyanide to defend itself against predators. This is something of a sensation, because this toxin is not generally present in the arsenal of the 80,000 known species of arachnids.

New nano-implant could one day help restore sight

Tue, 14/03/2017 - 12:16pm
A team of engineers has developed the nanotechnology and wireless electronics for a new type of retinal prosthesis that brings research a step closer to restoring the ability of neurons in the retina to respond to light. The researchers demonstrated this response to light in a rat retina interfacing with a prototype of the device in vitro.

Nearly all shoulder replacement patients under age 55 return to sports

Tue, 14/03/2017 - 12:16pm
A new study found that 96.4 percent of recreational athletes, age 55 and younger, who underwent total shoulder replacement surgery returned to at least one sport, on average, within seven months of surgery.

High rate of return to running following arthroscopic hip surgery

Tue, 14/03/2017 - 12:16pm
Ninety-six percent of patients who were recreational or competitive runners prior to developing hip bone spurs returned to their sport within nine months of arthroscopic surgery, according to new research.

Nearly half of today's high school athletes specialize in one sport

Tue, 14/03/2017 - 12:16pm
Youth single sport specialization -- training and playing just one sport, often year round and on multiple teams -- is a growing phenomenon in the US A new study found that 45 percent of high school athletes specialize in just one sport, two years earlier than current collegiate and professional athletes say they did.

High cholesterol levels linked with rotator cuff surgery failure

Tue, 14/03/2017 - 12:16pm
Patients with higher cholesterol levels face a significantly greater risk for failure of minimally invasive (arthroscopic) rotator cuff surgery, according to a new study. According to the study, commonly-used cholesterol lowering drugs, called statins, diminish this risk.

Home may be the best place to recover after total joint replacement surgery

Tue, 14/03/2017 - 12:16pm
Despite higher costs, many doctors recommend and some patients prefer, recovery at an in-patient rehabilitation facility following total hip (THR) or total knee replacement (TKR) surgery. And yet a new study found that even patients who live alone can recover effectively and safely at home.

Study paves the way for Clostridium difficile treatment in pill form

Tue, 14/03/2017 - 12:16pm
Frozen and freeze-dried products for Fecal Microbiota Transplantation (FMT) are nearly as effective as fresh product at treating patients with Clostridium difficile (C-diff) infection, according to researchers.

Increased risk of postop infection when surgery closely follows epidural steroid injection

Tue, 14/03/2017 - 12:16pm
Patients may wish to take a one- to three-month break from lumbar epidural steroid injections (LESIs) before undergoing lumbar spinal fusion surgery. Why? An increased risk of infection has been identified when LESIs are administered within 3 months prior to surgery.

Greenhouse gases: First it was cows, now it's larvae

Tue, 14/03/2017 - 12:16pm
A certain species of larva uses methane to propel itself, and it is even possible that this mechanism is accelerating the release of gases into the atmosphere and magnifying global warming, scientists have discovered. The research demonstrates the negative role played by the larvae not just in global warming but also in disturbing the sedimentary layers at the bottom of lakes.

Study casts doubt on whether internet filters in the home protect teenagers online

Tue, 14/03/2017 - 12:16pm
A new study finds no link between household internet filters and the likelihood of the teenagers in those households being better protected from unpleasant online material.
