Postmortem changes in meat quality and myofibrillar protein degradation in turkey breast muscle
… was assessed using measurements of colour and protein extractability, while quality characteristics of cooked product were assessed using cook yield and torsion gelometry. The extractability and degradation of 10 specific proteins was monitored using SDS-PAGE and Western blotting. Additionally, …

Effect of Dried Mushroom Powder on Thiol Content in Lyophilized and Native Bovine Myofibrillar Protein
… oxidation can form disulfide bonds that modify protein conformations, resulting in lower free thiol content. The effect of dried (lyophilized and oven-dried) mushroom powder<em> </em>(<em>Agaricus bisporus </em>or <em>Pleurotus ostreatus)</em> added to bovine lyophilized and native myofibrillar …

Skelettmuskelproteinumsatz nach kontrakturlösenden Operationen bei Patienten mit Duchenne-Muskeldystrophie
… ratio as an appropriate indicator for the myofibrillar protein catabolic rate (MPCR) in muscle disorders is discussed controversially. To explore this issue we studied the renal excretion of 3-MH over a period up to 24 months (on average 20.5 SD 2.1) after operation in 16 consecutive DMD …

Human obesity and its influence on muscle protein synthesis
… for high throughput of macronutrients, damaged proteins must be degraded and replaced on a continual basis. Moreover, amino acids from meals are crucial for the muscle to replace those lost for other needs (e.g. gluconeogenesis and oxidation). Skeletal muscle appears to be more responsive to …

Ante- and post-mortem factors affect muscle protein functionality from fish
… and shear force. Brining time linearly increased myofibrillar protein solubility, fillet weight loss after brining, water-phase salt content, and cooked ash content and linearly decreased water activity and brined and cooked moisture content. An 8.7% (w/v) brine and 90-min brining time resulted in …

The effect of whey protein-polyphenol on the recovery of muscle function and strength following eccentric exercise- the myogenic and neural contributions to eccentric exercise.
… eccentric exercise have been studied with whey protein and polyphenols, both of which support recovery via muscle protein synthesis and antioxidant & anti-inflammatory effects, respectively. However, whether their combined effect supports recovery above that of supplementing independently …

The rigor bond’s interaction with protein denaturation : effects on water-holding of myofibrils
… understand the rigor bonds’ effect together with protein denaturation on water-holding capacity by breaking the actomyosin bonds that were formed during rigor process and examining the dissociation of actomyosin bonds’ influence on rheological features of myofibrils in suspension. In this study …

Purification and some properties of an alkaline protease from rat skeletal muscle
… may play an important role in the metabolism of myofibrillar and other muscle proteins and as such deserve to be fully characterised. In this study, a major myofibrillar alkaline protease was purified from rat skeletal muscle. The enzyme degraded both denatured casein and azocasein and had a pH …

Oyster Mushroom (Pleurotus ostreatus) Stipe Peptides as in-vitro Radical Scavenging, Ferrous Iron Chelating, & Ferric Reducing Antioxidant Compounds
… Additionally, the effects of peptides on protein carbonyl formation during myofibrillar oxidation is unknown. Oxidation of lysine, arginine, and proline in myofibrillar protein from red meat results in reduced meat quality owing to changes in water composition. Therefore, the objective of …

Effects of four weeks of daily soy or dairy milk ingestion on the exercise-induced proteolytic responses in plasma and skeletal muscle in a post-menopausal female population.
… degradation pathways account for the majority of myofibrillar protein degradation seen with muscle atrophy. The purpose of this study was to investigate the effects of daily consumption of soy or dairy milk in older females on systemic plasma and local skeletal muscle markers of muscle proteolysis …

Mechanisms Regulating Resistance Training Mediated Hypertrophy in Human Skeletal Muscle
… sex are unclear. The extent of post-exercise myofibrillar protein synthesis (MyoPS), satellite cells (SC) and dietary amino acids to promote muscle hypertrophy have generally been investigated independently in controlled lab based settings and predominately in males; therefore this …

The Biological Basis for Toughness in Beef
… thesis was to elucidate role of small heat shock proteins (sHSPs) in the development of tenderness in beef. Data in this thesis were predominantly obtained from bull M. longissimus dorsi aged at -1.5°C for up to 28 days post mortem. High (pH ≥ 6.2) and low (≤ 5.79) ultimate pH (pHu) at were …

Positioning Microtissues on the Differentiation Continuum Reveals their Utility for Studying Skeletal Myopathies and Metabolic Disease
… in force generation, myokine signaling, and protein synthesis, thereby establishing a multiplex platform for the study of dysregulation in T2D. First, to ensure accurate contractile assessments, we developed protocols to identify the electrical field stimulation parameters eliciting peak …

Evaluation of the quality of individual quick frozen fish products.
… in regard to the integrity of muscle structure, myofibrillar protein denaturation and aggregation, lipid degradation, texture and sensory changes. This information would be useful for achieving optimal conditions for freezing these species and assessing their quality during frozen storage for …

Proteomic analysis of diurnal variation in human skeletal muscle performance
… changes in the abundance of hundreds of proteins simultaneously. To date, such techniques have not been used to specifically characterise the human myofibrillar proteome, or study how the myofibrillar proteome relates to muscle outputs such as peak isometric force or the velocity of …

Chronic Dietary Supplementation of Branched-Chain Amino Acids Does Not Attenuate Muscle Torque Loss in a Mouse Model of Duchenne Muscular Dystrophy
… dystrophin or the complete absence of the protein dystrophin, resulting in necrosis and fibrosis in the muscle, loss of ambulation, cardiomyopathies, inadequate or failure of respiratory function, and decreased lifespan. Although there has been little research for effective nutritional …

The activity and content of calpains in maturing dystrophic muscle membranes
… was greater relative calpain activity in the myofibrillar supernatant fraction in mdx (15.13AU) than wt mice (1.18AU; p<0.05). This could indicate calpain's role in the initiation of myofibrillar protein turnover and the proteolysis of submembranous networks in the mdx muscles. 5. At age 21-d, …
