Myofibrillar protein pattern in experimental myotonia in rats

Journal of the Neurological Sciences, 1976
Experimental myotonia was induced in rats by long-term administration of 20,25-diazacholesterol. Electrophysiological, morphological and biochemical investigations were carried out on m. soleus, m. extensor digitorum longus and m. gastrocnemius. The effect of 20,25-diazacholesterol administration on myofibrillar proteins was studied and a significant ...

PRESSURE‐INDUCED SOLUBILIZATION OF MYOFIBRILLAR PROTEINS

Journal of Food Science, 1976
ABSTRACT In an earlier study it was found that the application of high pressure to homogenates of meat in saline solution could increase water‐holding capacity and promote the solubilization of proteins. These studies have now been extended to myofibrils prepared from sheep semimembrano‐sus muscle. The amount of protein solubilized by

The effect of acidification on myofibrillar proteins

Meat Science, 1994
Isolated myofibrillar proteins of mutton, beef and chicken were treated with an acidulent to give various pH values and stored at 5°C for 20 h before analysing the proteins using sodium dodecylsulphate polyacrylamide gel electrophoresis. It was found that protein degradation occurred below pH 4·5, with a decrease in band intensity of all major ...

Myofibrillar protein synthesis in young and old men

American Journal of Physiology-Endocrinology and Metabolism, 1993
We tested the hypothesis that healthy older men (> 60 yr old) have a slower rate of myofibrillar protein synthesis than young men (< 35 yr old). Myofibrillar protein synthesis was determined by the in vivo incorporation of L-[1-13C]leucine into myofibrillar proteins obtained by muscle biopsy. Subjects were eight young (21-31 yr) and eight older (

Phosphorylation of cardiac myofibrillar proteins.

Recent advances in studies on cardiac structure and metabolism, 1978
The P light chain of cardiac myosin is phosphorylated and dephosphorylated by highly specific enzymes. These reactions take place in the beating rabbit heart and there is evidence that dephosphorylation of the light chain occurs during the inotropic response produced by adrenaline.

Magnetic fields improve the gel properties of myofibrillar proteins in low-salt myofibrillar protein emulsion systems

Food Chemistry
The effect of magnetic field on the properties of emulsified gels containing myofibrillar protein (MP-emulsified gels) with different salt concentration (0, 0.2, 0.4, 0.6 mol/L) were investigated. The results demonstrated that the magnetic field treatment (4 °C, 3.8 mT, 3 h) made the emulsion droplets smaller and more uniform.

Decreased myofibrillar protein breakdown following treatment with clenbuterol

Journal of Surgical Research, 1991
Daily treatment of Fischer-344 rats for 14 days with the beta 2-adrenergic agonist, clenbuterol, increased gastrocnemius muscle mass and protein content. Coadministration with the beta-adrenergic antagonist, nadolol, significantly reduced these anabolic effects of clenbuterol.

Regulation of Myofibrillar Protein Gene Expression

1989
The contraction of skeletal and cardiac muscle is the result of a physiological conversion of chemical energy into mechanical energy, which takes place in a highly ordered three dimensional matrix of myofibrillar proteins. The basic unit of the contractile process in striated muscle is the sarcomere (Squire, 1981), which is composed of thick and thin ...

Acute resistance exercise augments integrative myofibrillar protein synthesis

Metabolism, 2012
The purpose of this study was to determine whether an acute bout of high-intensity resistance exercise (RE) would augment integrative mixed muscle and myofibrillar protein fractional synthesis rates (FSRs) when total energy and macronutrient intake was controlled.

In vitro non-enzymatic glycosylation of myofibrillar proteins

International Journal of Biochemistry, 1993
1. Glycation is non-enzymatic modification of proteins by sugars in which not only structural but also biological properties of proteins are altered. 2. Our in vitro experiments show that incubation of myofibrillar proteins with ribose results in sugar attachment to proteins and at the same time myofibrillar ATPase activity is lowered. 3.
