The University of Minnesota Medical School continues its legacy of advancing cell replacement therapies with a scientific breakthrough that highlights the promise of cell therapies for muscular dystrophy. The research published in Proceedings of the National Academy of Sciences of the United States of America (PNAS) allows authors Tania Incitti, Ph.D., Post-Doctoral Associate, and Rita […]Continue Reading ...
Credit: CC0 Public Domain Hypertrophic cardiomyopathy (HCM) is the most common genetic disease of the heart and a leading cause of sudden cardiac death in young people and athletes. Scientists have long known that the condition’s cardinal feature—an unusually thick heart muscle that contracts and relaxes abnormally—is fueled by some glitch in the heart’s molecular […]Continue Reading ...
A high-protein, low-calorie diet helps older adults with obesity lose more weight, maintain more muscle mass, improve bone quality and lose “bad” fat, according to results from a new randomized controlled trial led by Wake Forest University researcher Kristen Beavers. Four research papers based on the study results have been accepted for publication in peer-reviewed […]Continue Reading ...
Loss of muscle and body weight is associated with disability after stroke, reports a study presented today at Heart & Stroke 2019, a meeting of the European Society of Cardiology (ESC) Council on Stroke, and published in the Journal of Cachexia, Sarcopenia and Muscle. Study author Dr Nadja Scherbakov, of the Centre for Stroke Research […]Continue Reading ...
Long, heavy limbs such as arms or legs differ fundamentally from short, light limbs such as fingers in their ability to execute fast movements. While the central nervous system has to actively control fast movements of large limbs, passive muscle force can suffice for the movement velocity and movement amplitude of small and light limbs. […]Continue Reading ...
83 percent of children in small study experienced atrophy in at least one muscle group Children with life-threatening respiratory failure who require mechanical ventilation in a pediatric intensive care unit commonly experience rapid muscle atrophy, according to a study published online Dec. 19, 2018, in PLOS ONE. More than 80 percent of children enrolled in […]Continue Reading ...
Overview Electromyography (EMG) is a diagnostic procedure to assess the health of muscles and the nerve cells that control them (motor neurons). EMG results can reveal nerve dysfunction, muscle dysfunction or problems with nerve-to-muscle signal transmission. Motor neurons transmit electrical signals that cause muscles to contract. An EMG uses tiny devices called electrodes to translate […]Continue Reading ...
WEDNESDAY, Nov. 21, 2018 — When you first start strength training, almost any weight you lift will bring some results. But also use this time to learn proper form, the American College of Sports Medicine advises. As you progress, you can zero in on the best amount of weight as well as the number of […]Continue Reading ...
Elderly to feel fitter, faster and stronger Researchers from The University of Texas Medical Branch at Galveston have developed a promising drug that has proven to significantly increase muscle size, strength and metabolic state in aged mice, according to a study just published in Biochemical Pharmacology. As we age, our bodies increasingly lose the ability […]Continue Reading ...
Muscle co-contraction is a strategy used commonly in elderly people to increase their stability. Co-contraction involves the simultaneous contraction of pairs of muscles from opposing groups to lock a joint and provide stability. However, co-contraction can also lead to stiffness, which in turn reduces stability, which is why some authors have suggested the opposite approach […]Continue Reading ...
Non-invasive magnetic stimulation ‘tricks’ muscle cells into thinking that they are exercising, and amplifies the biological effect to promote muscle regeneration The journey of muscle rehabilitation can be long and arduous, and requires strong perseverance from the patient. Now, researchers from the National University of Singapore (NUS) are making the recovery process much easier for […]Continue Reading ...
What started as research pertaining to viral infections has unexpectedly led to the discovery of a first-in-class enzyme in mammals that modifies muscle proteins to help them grow and remain strong. According to a Stanford News article, the discovery of the enzyme, called SETD3, solves a 50-year-old mystery of how and why a specific modification (often […]Continue Reading ...
The innate immune system comprises of various soluble factors that provide the first line of defense against pathogens. Transforming Growth Factor type Beta 1 (TGF-β1) is one such soluble factor that also regulates skeletal muscle function, and it one of the most studied factors. TGF-Beta 1 is a potent modulator of immune and glial cell […]Continue Reading ...
To help patients with muscle disorders, scientists at The University of Texas Health Science Center at Houston (UTHealth) have engineered a new stem cell line to study the conversion of stem cells into muscle. Findings appeared in Cell Reports. “We have also developed a more efficient strategy to make muscles from human stem cells. Scientists […]Continue Reading ...
Skeletal muscle tissue. Credit: University of Michigan Medical School All vertebrates need muscles to function; they are the most abundant tissue in the human body and are integral to movement. In a recent article published in Nature Communications, an international team of researchers discovered two proteins essential to the development of skeletal muscle. This research, […]Continue Reading ...
