The effect of milk consumption immediately following resistance exercise on protein degradation in untrained males before and after a 10-week resistance training protocol
… immediately after resistance exercise on muscle protein breakdown before and after a 10-week resistance training program. Nineteen untrained males, 18-25 years of age, consumed either a carbohydrate-electrolyte (CHO) or milk (MILK) beverage immediately after a strenuous leg resistance exercise …

Amino Acid Sensing in Muscle: Role of the lysosome and the effect of protein supplementation on improving amino acid sensitivity in aging muscle
Protein ingestion is a well-studied stimulus for increasing skeletal muscle protein synthesis. Only recently has the mechanism for this phenomenon been elucidated at the cellular level. To this point, most of the mechanistic research into this process has been conducted in human embryonic kidney …

Characterization of Fava Bean Hydrolysates for Future Use in Protein Enriched Beverages
… in plant-based, non-dairy beverages. Their high protein content and balanced amino acid profile make them a promising alternative to whey protein, which is non-vegan and a common allergen. This study aimed to determine how partial hydrolysis of fava bean protein isolate using the food-grade …

TEMPERATURE VARIATION IN MARQUETTE, MICHIGAN, CONCERNING SKELETAL MUSCLE DEGRADATION PATTERNS FOR POSTMORTEM INTERVAL DETERMINATION
… methods can estimate PMI by analyzing changes in protein breakdown within muscle tissue. Observing protein degradation has been proposed as a new method of PMI estimation due to specific proteins degrading in a predictable and time-dependent manner. This study examined the effect of temperature on …

Characterization of Extracellular Proteolytic Activity From Prevotella Ruminicola and Streptococcus Bovis
… study was that by isolating and characterizing proteinases from two of the predominant bacterial species in the rumen, Prevotella ruminicola and Streptococcus bovis, the understanding of the breakdown of dietary N in the rumen would be improved. Studies of how Prevotella ruminicola B$\sb1$4 …

The effect of leucine and dileucine ingestion on muscle protein turnover in healthy young men
… is determined by day-to-day changes in muscle protein synthesis (MPS) and muscle protein breakdown rates (MPB), are important determinants of physical performance and metabolic health across all age groups. As such, identifying nutritional and exercise strategies that more robustly stimulate …

Effects of physical activity levels and nutritional intake on skeletal muscle protein turnover and cellular signaling
… levels (combined with essential amino acids) on protein turnover and cellular signaling following resistance exercise, and to investigate similar parameters in response to various combinations of anabolic nutrients. Stable isotopic techniques with arterial/venous catheterization and muscle …

Effects of lower- and higher- volume resistance exercise on serum testosterone and skeletal muscle androgen receptor content in men : subsequent effects on the mRNA expression of insulin- like growth factor peptide and myostatin in skeletal muscle.
… receptor–DNA binding increases muscle protein synthesis and reduces muscle protein breakdown. In addition, the testosterone level can alter the expression of insulin–like growth factor and myostatin which are key regulators of muscle protein balance. Higher-intensity resistance exercise …

The effects of testosterone propionate on hindlimb immobilized rats
… pronounced catabolism of many skeletal muscle proteins. Strength, V02 max, oxidative enzyme activities, protein synthesis, and muscle weight are all diminished due to chronic limb immobilization.Testosterone is classified as an anabolic steroid which has the effect of increasing protein …

Essential Amino Acid (EAA) Regulation of Skeletal Muscle Protein Turnover with Age
… vitro studies model how EAA can regulate muscle protein synthesis (MPS), the relevance of these models to muscle protein breakdown (MPB) and the presence of physiological EAA concentrations remains to be established. Therefore, the objective of this study was to determine the effects of a low, …

Plasma amino acid and metabolite changes in pigs during endotoxemia
… been used as an indirect marker of muscle protein breakdown in rodents and humans. However, the major form (i.e., free or acetylated) of NτMH in pig plasma was unknown. Results indicate that only 15% of plasma NτMH is in the free form and the remainder is acetylated. Furthermore, LPS …
