Transcriptomics reveals transient and dynamic muscle fibrosis and atrophy differences following spinal cord injury in rats

Autor: Hui Jean Kok, Drew B. Fletcher, Jacob C. Oster, Christine F. Conover, Elisabeth R. Barton, Joshua F. Yarrow

Publikováno v: Journal of Cachexia, Sarcopenia and Muscle, Vol 15, Iss 4, Pp 1309-1323 (2024)

Abstract Background The rate and magnitude of skeletal muscle wasting after severe spinal cord injury (SCI) exceeds most other disuse conditions. Assessing the time course of molecular changes can provide insight into the progression of muscle wastin

Combined action observation and mental imagery versus neuromuscular electrical stimulation as novel therapeutics during short‐term knee immobilization

Autor: Kylie K. Harmon, Ryan M. Girts, Gabriela Rodriguez, Jonathan P. Beausejour, Jason I. Pagan, Joshua C. Carr, Jeanette Garcia, Michael D. Roberts, Debbie L. Hahs‐Vaughn, Jeffrey R. Stout, David H. Fukuda, Matt S. Stock

Publikováno v: Experimental Physiology, Vol 109, Iss 7, Pp 1145-1162 (2024)

Abstract Limb immobilization causes rapid declines in muscle strength and mass. Given the role of the nervous system in immobilization‐induced weakness, targeted interventions may be able to preserve muscle strength, but not mass, and vice versa. T

Measurement of Knee Extensor Torque During Repetitive Peripheral Magnetic Stimulation: Comparison of the Forces Induced by Different Stimulators

Autor: Masanori Kamiue, Akio Tsubahara, Tomotaka Ito, Yasuhiro Koike

Publikováno v: Annals of Rehabilitation Medicine, Vol 48, Iss 3, Pp 203-210 (2024)

Objective To investigate the factors that induce strong contractions during repetitive peripheral magnetic stimulation (rPMS) and compare the muscle torque induced by two stimulators (Stim A and Stim B) with different coil properties. Methods rPMS wa

Short‐term disuse does not affect postabsorptive or postprandial muscle protein fractional breakdown rates

Autor: George F. Pavis, Doaa R. Abdelrahman, Andrew J. Murton, Benjamin T. Wall, Francis B. Stephens, Marlou L. Dirks

Publikováno v: Journal of Cachexia, Sarcopenia and Muscle, Vol 14, Iss 5, Pp 2064-2075 (2023)

Abstract Background The decline in postabsorptive and postprandial muscle protein fractional synthesis rates (FSR) does not quantitatively account for muscle atrophy during uncomplicated, short‐term disuse, when atrophy rates are the highest. We so

Hispidin‐enriched Sanghuangporus sanghuang mycelia SS‐MN4 ameliorate disuse atrophy while improving muscle endurance

Autor: I‐Chen Li, Ting‐Yu Lu, Ting‐Wei Lin, Andy Y. Chen, Hsin‐Tung Chu, Yen‐Lien Chen, Tsung‐Ju Li, Chin‐Chu Chen

Publikováno v: Journal of Cachexia, Sarcopenia and Muscle, Vol 14, Iss 5, Pp 2226-2238 (2023)

Abstract Background Disuse atrophy is a frequent cause of muscle atrophy, which can occur in individuals of any age who have been inactive for a prolonged period or immobilization. Additionally, acute diseases such as COVID‐19 can cause frequent se

An electrical stimulation intervention protocol to prevent disuse atrophy and muscle strength decline: an experimental study in rat

Autor: Haiwang Shi, Fan Li, Fulong Zhang, Xiaobei Wei, Chengyi Liu, Rui Duan

Publikováno v: Journal of NeuroEngineering and Rehabilitation, Vol 20, Iss 1, Pp 1-11 (2023)

Abstract Background Skeletal muscle is negatively impacted by conditions such as spaceflight or prolonged bed rest, resulting in a dramatic decline in muscle mass, maximum contractile force, and muscular endurance. Electrical stimulation (ES) is an e

Nicotinamide Phosphoribosyltransferase‐elevated NAD+ biosynthesis prevents muscle disuse atrophy by reversing mitochondrial dysfunction

Autor: Yao Zhang, Yingming Wang, Shuai Lu, Rui Zhong, Zhilin Liu, Qichun Zhao, Chongyang Wang

Publikováno v: Journal of Cachexia, Sarcopenia and Muscle, Vol 14, Iss 2, Pp 1003-1018 (2023)

Abstract Background It is well known that muscle disuse atrophy is associated with mitochondrial dysfunction, which is implicated in reduced nicotinamide adenine dinucleotide (NAD+) levels. Nicotinamide phosphoribosyltransferase (NAMPT), a rate‐lim

Extracellular vesicle distribution and localization in skeletal muscle at rest and following disuse atrophy

Autor: Ahmed Ismaeel, Douglas W. Van Pelt, Zachary R. Hettinger, Xu Fu, Christopher I. Richards, Timothy A. Butterfield, Jonathan J. Petrocelli, Ivan J. Vechetti, Amy L. Confides, Micah J. Drummond, Esther E. Dupont-Versteegden

Publikováno v: Skeletal Muscle, Vol 13, Iss 1, Pp 1-16 (2023)

Abstract Background Skeletal muscle (SkM) is a large, secretory organ that produces and releases myokines that can have autocrine, paracrine, and endocrine effects. Whether extracellular vesicles (EVs) also play a role in the SkM adaptive response an
