Nature: Central components of muscles of higher animals much older than assumed A characteristic feature of most animals is their ability to move quickly with the help of their musculature. Animals that can move are able to flee, hunt for prey, travel long distances or conquer new habitats. The evolution of muscles was thus a fundamental step during animal evolution. While the structure and function of muscles, especially of vertebrates, have been intensively studied, the evolutionary...

An actin-ratchet tightens the contractile ring that severs budding daughter cells from their yeast mothers During the final stage of cell division, a short-lived contractile ring constricts the cellular membrane and eventually separates the dividing cell in two. Although this "molecular muscle's" composition, mainly actin and myosin, is similar to its skeletal counterpart, the force-producing mechanism is fundamentally different, report researchers at the Stowers Institute for Medical...

Discovery could be used to help engineer artificial tissue A study led by researchers from McGill University provides new insights into the structure of muscle tissue in the heart — a finding that promises to contribute to the study of heart diseases and to the engineering of artificial heart tissue. The research, published in the Proceedings of the National Academy of Sciences (PNAS), reveals that the muscle fibers in the heart wall are locally arranged in a special "minimal...

The candy bar you swallowed right before jumping on your bicycle keeps you going only so long before the muscles in your legs and hips reach for something with more power — the long chain fatty acids stored to keep you moving for hours. In a report in the journal Cell Metabolism, Dr. Bert O'Malley, professor and chair of molecular and cellular biology at Baylor College of Medicine, Dr. Brian York, assistant professor in the same department, and colleagues at BCM describe how a...

Weight training at a lower intensity but with more repetitions may be as effective for building muscle as lifting heavy weights says a new opinion piece in Applied Physiology, Nutrition, and Metabolism. "The perspective provided in this review highlights that other resistance protocols, beyond the often discussed high-intensity training, can be effective in stimulating a muscle building response that may translate into bigger muscles after resistance training," says lead author Nicholas...

Team hopes findings will bolster practice´s reputation as a nonpharmacolgical treatment A team of Japanese researchers will reveal study results Monday at the Experimental Biology 2012 meeting that show how acupuncture therapy mitigates skeletal muscle loss and holds promise for those seeking improved mobility through muscle rejuvenation. "It is my hope that this study will demonstrate acupuncture's feasibility with regard to improving health among the elderly and medical patients....

Case Western Reserve researchers identify role of Kruppel-like Factor 15 in fat burning and exercise endurance While exercise is accepted universally as the most beneficial prescription physicians can write for patients, little is known about the molecular mechanisms that generate its widespread health benefits. Researchers from Case Western Reserve School of Medicine have shed light on this mystery by discovering that a genetic factor, Kruppel-like Factor 15 (KLF15), governs the body's...

Researchers from the Department of Chemistry and Molecular Biology at the University of Gothenburg have managed for the first time to obtain detailed information about the role of the protein metastasin in the spread of tumor cells. Published recently in the renowned Proceedings of the National Academy of Sciences (PNAS), the study paves the way for the development of new drugs. Metastasin is a protein with a key role in the spread of tumor cells. Previous research has shown that it is...

Russians born during the Leningrad Siege in World War II, which was responsible for some of the greatest losses of civilian life in history, are giving scientists new strategies to identify people who experienced intrauterine growth restriction (IUGR) and starvation during childhood at greatest risk of developing long term heart complications.vThe abstract study´, presented at the Frontiers in CardioVascular Biology (FCVB) meeting, in London, UK, 30 March to 1 April 2012, makes use of a...

Spinal muscular atrophy (SMA) is an incurable, and progressive, disease caused by an inheritable defect in the gene SMN1. Depending on the severity of the mutation it can result in the loss of spinal cord motor neurons, muscle wasting (atrophy) and even death of an affected child. A new study published in Biomed Central's open access journal BMC Medicine shows that Fasudil, a ROCK inhibitor, can improve both the size of muscle fibers and their connection to motor neurons. Fasudil also...


Word of the Day
baudekin
  • A rich embroidered or brocaded silk fabric woven originally with a warp of gold thread.
'Baudekin' seems to be an alternative form of 'baldachin,' from the Italian 'Baldacco,' Baghdad, the city where the material was made.
