Total-body skeletal muscle mass:estimation by a new dual-energy X-ray absorptiometry method
Body composition nutritional assessment skeletal muscle mass magnetic resonance imaging dual-energy X-ray absorptiometry
2016/12/19
Background: Skeletal muscle (SM) is an important body-composition component that remains difficult and impractical to quantify by most investigators outside of specialized research centers. A lar...
Changes in skeletal muscle and organ size after a weight-loss intervention in overweight and obese type 2 diabetic patients
type 2 diabetes magnetic resonance imaging body composition skeletal muscle organ mass weight loss Look AHEAD trial
2018/11/12
Background: The effect of a weight-loss intervention on the masses of lean tissues and organs in humans is not well known.Objective: We studied the effects of a diet and exercise weight-loss intervent...
Effects of polymorphism in the bovine PTPRQ gene on the expression of MYF6 and MYF5 genes in skeletal muscle and on meat production traits in beef bulls
receptor-type III PTP with phosphatidylinositol phosphatase activity genotype muscle regulatory factors bovine meat traits
2016/6/3
The aim of the study was to characterize nucleotide sequence polymorphisms in the bovine PTPRQ gene, to search for their possible effect on the expression of myogenic factor 6 (MYF6; MRF4) and myogeni...
Effects of an omnivorous diet compared with a lactoovovegetarian diet on resistance-training-induced changes in body composition and skeletal muscle in older men
Elderly men lactoovovegetarian diet muscle creatine
2016/6/2
Very limited data suggest that meat consumption
by older people may promote skeletal muscle hypertrophy in
response to resistance training (RT).
Determination of skeletal muscle and fat-free mass by nuclear and dual-energy X-ray absorptiometry methods in men and women aged 51–84 y
bioimpedance analysis aging anthropometry
2016/6/1
Skeletal muscle mass (SMM) and fat-free mass
(FFM) are important variables in nutritional studies. Accurate
techniques for measuring these variables have not been thoroughly
validated in elderly su...
Physical activity, protein intake, and appendicular skeletal muscle mass in older men
Aging sarcopenia uniaxial accelerometer
2016/5/31
Aging is associated with physical inactivity, low
energy intake, and loss of skeletal muscle mass. It is not clear
whether regular physical activity and adequate dietary protein
intake can attenuat...
Identification of Histone Deacetylase 2 as a Functional Gene for Skeletal Muscle Development in Chickens
Histone Deacetylas Post Genome-Wide Association Study Gene Expression Myogenesis
2016/5/19
A previous genome-wide association study (GWAS) exposed histone deacetylase 2 (HDAC2) as a possible candidate gene for breast muscle weight in chickens. The present research has examined the possible ...
Effects of Nitric Oxide Synthase Inhibition on Fiber-Type Composition, Mitochondrial Biogenesis,and SIRT1 Expression in Rat Skeletal Muscle
Mitochondrial biogenesis muscle fiber composition nitric oxide nitric oxide synthase silent information regulator of transcription
2016/1/9
It was hypothesized that nitric oxide synthases (NOS) regulated SIRT1 expression and lead to a corresponding changes of contractile and metabolic properties in skeletal muscle. The purpose of the pres...
Effects of oral phosphatidic acid feeding with or without whey protein on muscle protein synthesis and anabolic signaling in rodent skeletal muscle
phosphatidic acid feeding muscle protein synthesis
2015/9/8
Phosphatidic acid (PA) is a diacyl-glycerophospholipid that acts as a signaling molecule in numerous
cellular processes. Recently, PA has been proposed to stimulate skeletal muscle protein accretion,...
Microcurrent Electrical Neuromuscular Stimulation Facilitates Regeneration of Injured Skeletal Muscle in Mice
Muscle injury regenerative potential
2015/8/28
Conservative therapies, mainly resting care for the damaged
muscle, are generally used as a treatment for skeletal muscle
injuries (such as muscle fragmentation). Several past studies
reported t...
Effects of protein type and composition on postprandial markers of skeletal muscle anabolism, adipose tissue lipolysis, and hypothalamic gene expression
Whey protein Egg protein Hydrolyzed protein
2015/7/30
Skeletal muscle analyses revealed that compared to CTL: a) phosphorylated (p) markers of mTOR signaling [p-mTOR (Ser2481) and p-rps6 (Ser235/236)] were elevated 2–4-fold in all protein groups 90 min p...
