University of Nevada School of Medicine researcher reviews muscular dystrophy therapies

'A Molecular Bandage for Diseased Muscle' appears today in prestigious Science publication

2012-06-22

(Press-News.org) RENO, Nev. – Leading muscular dystrophy researcher Dean Burkin, of the University of Nevada School of Medicine summarizes the impact of a new protein therapeutic, MG53, for the treatment of Duchenne muscular dystrophy in an article published this week in Science Translational Medicine.

"This is a focus article in which we summarize the impact of MG53 protein therapy as a treatment option and discuss the increasing number of new protein therapeutics being developed for the muscular dystrophies, including laminin-111 developed in our laboratory," Burkin, a pharmacological researcher and associate professor, said.

The article, "A Molecular Bandage for Diseased Muscle," co-authored by Ryan Wuebbles, a post-doctoral student in Burkin's lab in the University's Center for Molecular Medicine, is a review of the current status of therapeutic developments in the muscular dystrophy research field. These therapies represent significant strides and show great promise in treatment of muscular dystrophy.

Approaches to treat Duchenne muscular dystrophy include gene replacement therapy, gene repair and myoblast cell transfer.

In a study on MG53 by Noah Weislander and colleagues, presented in the same issue of Science Translational Medicine, it was found that mice that lack MG53 developed progressive muscle weakness and exhibit defective muscle repair after exercise or injury, and that MG53 facilitates rapid membrane repair to prevent damage to normal muscle.

The study suggests that treatment in combination with other protein therapies such as Burkin's laminin-111 therapy, are likely to have synergy as well for Duchenne and other muscular dystrophies.

Burkin's published research on laminin-111, a naturally occurring protein, showed it is quickly picked up in the bloodstream of mice and prevents muscle damage, an important finding for Duchenne muscular dystrophy, the most common form of muscular dystrophy.

He recently co-hosted Myomatrix 2012, a conference for leading muscular dystrophy scientists and clinicians to explore and share their latest findings and data on treatment breakthroughs. The conference was held at the University of Nevada, Reno campus, where research by Burkin has led to a potential new therapy for muscular dystrophy.

Failure to Use Turn Signals Cause More Accidents Than Cellphones

2012-06-22

In recent months, there has been a veritable plethora of discussion in the media about the dangers of distracted driving. Although distracted driving is a proven danger to motorists, a new study suggests that it may not be as significant of a cause of car accidents as it was once thought. The study found that a technological feature that has been on vehicles almost since their inception -- turn signals -- is to blame for more collisions than being distracted by newfangled technology. According to research conducted by the Society of Automotive Engineers, drivers fail ...

West Virginia Governor Signs Coal Mining Safety Bill

2012-06-22

Safer coal mining operations in West Virginia have been a renewed priority for many lawmakers since the Upper Big Branch explosion two years ago. That includes House Speaker Rick Thompson, whose father long ago died in a coal mining roof fall accident. A new coal mining safety bill sponsored by Speaker Thompson passed both chambers by narrow margins this session, and was signed by Gov. Earl Ray Tomblin in March. A range of new measures will take effect in June, including: - Establishment of an anonymous mining safety tip line - Increases in fines and penalties for ...

Cameras and Intersection Safety: Red and Yellow Is Not Black and White

2012-06-22

What is the overall effect on safety when cameras are installed at intersections to detect traffic violations? Red-light cameras, as they are commonly known, have been controversial in the Chicago area and in several other cities across the country. Their advocates present them on public safety grounds, as a way to prevent people from running red lights by using technology to automatically issue a ticket to violators. There are several concerns, however, that accompany use of this tactic. Civil liberties proponents argue that the specter of Big Brother lurks in letting ...

Risks and rewards of quantifying nature's 'ecosystem services'

2012-06-22

How much is a stream worth? Can we put a dollar value on a wetland? Some conservation proponents have moved to establish the economic value of "ecosystem services," the benefits that nature provides to people. The approach translates the beauty and utility of a wetland into pounds of phosphorus removed from agricultural runoff, Joules of heat pulled out of urban wastewater, and inches of floodwater absorbed upstream of riverside communities. The idea of trading ecosystem services has surged in popularity since the 2005 United Nations Millennium Ecosystem Assessment. But ...

Silent Killer: Hospital Infections Affect 1 in 20 Patients

2012-06-22

When most people are admitted to the hospital, their primary concern is getting better and going home. To that end, a lot of people worry that their surgeries will not be successful, or that their doctors will make a diagnostic mistake or medication error. Most aren't aware that a silent killer is lurking in the background. Unfortunately, hospital-based infections are a huge problem in American medical facilities. According to the U.S. Centers for Disease Control and Prevention, approximately 1 in 20 hospitalized patients will develop an infection during their stay. ...

Bringing down the cost of fuel cells

2012-06-22

Engineers at the University of Wisconsin-Milwaukee (UWM) have identified a catalyst that provides the same level of efficiency in microbial fuel cells (MFCs) as the currently used platinum catalyst, but at 5% of the cost. Since more than 60% of the investment in making microbial fuel cells is the cost of platinum, the discovery may lead to much more affordable energy conversion and storage devices. The material – nitrogen-enriched iron-carbon nanorods – also has the potential to replace the platinum catalyst used in hydrogen-producing microbial electrolysis cells (MECs), ...

Hey, Repo Man: Court Says Give the Car Back

2012-06-22

The U.S. Court of Appeals for the Seventh Circuit has ruled that creditors must give repossessed property back - even though it was repossessed legally - after debtors file for Chapter 13 bankruptcy. The Facts In the case, the General Motors Acceptance Corporation (GMAC) repossessed Theodore Thompson's 2003 Chevy Impala after he fell behind on payments. On February 5, 2008, soon after repo men took the car, Thompson filed Chapter 13 bankruptcy. Thompson asked GMAC to return the car but GMAC refused. Bankruptcy Court Decides Against Thompson The bankruptcy court, ...

Bandgap engineering for high-efficiency solar cell design

2012-06-22

ZnSnP2, an absorber material for solar cells, transitions from an ordered to a disordered structure at high temperatures. Researchers from University College London and the University of Bath have proposed taking advantage of this structural change to design high-efficiency solar absorbers. The team used theoretical calculations to investigate the electronic structure of both phases, and predicted a significant difference in the bandgap between the ordered and fully disordered materials. Experimental measurements of the bandgap of ZnSnP2 are consistent with predictions ...

Sea waves as renewable resource in new energy converter design

2012-06-22

Sea waves are a renewable and inexhaustible resource found in abundance across the planet. But efficiently converting sea wave motion into electrical energy has been challenging, in part due to the difficulty of compensating for the relatively low speeds and irregular movements of ocean waves. Researchers from the University of Beira Interior in Portugal have designed and simulated a new energy conversion device that addresses both these challenges (i.e., low speed and irregular movements). Their proposed device consists of a floating body attached to a new type of conversion ...
