This study was conducted to determine effects of dietary administration of different levels of ginger (Zingiber officinale) extract on digestive enzymes activity and liver composition of Mesopotamichthys sharpeyi during eight weeks. In this respect, 192 M. sharpeyi fingerlings (with initial weight 11.67 ± 0.32 g) were divided into three ginger extract (0.1%, 0.5%, 1%) treatment group...

OBJECTIVE Glycogen, the largest cytosolic macromolecule, acquires solubility, essential to its function, through extreme branching. Lafora bodies are aggregates of polyglucosan, a long, linear, poorly branched, and insoluble form of glycogen. Lafora bodies occupy vast numbers of neuronal dendrites and perikarya in Lafora disease in time-dependent fashion, leading to intractable and fatal progre...

Various methods are used to prevent the deterioration of biotechnological properties brewer’s yeast during storage. This paper studied use artificial neural networks for mathematical modeling correcting biosynthetic activity seed C34 race storage with natural minerals. The input parameters were suspending medium (water, beer wort, or young beer); type zeolite-containing tuff from Siberian depos...

1. The variation in cellular glycogen content of differentiating cells derived from myxamoebae that initially contained a wide range of glycogen contents (0.047-5.56mg of glycogen/10(8) myxamoebae) has been studied. 2. Myxamoebae that initially contained 0.047-3.62mg of glycogen/10(8) myxamoebae all gave rise to fruiting bodies that contained similar amounts of glycogen (0.06-0.11mg of glycogen...

Glycogen and fructose 2,6-bisphosphate levels in rat liver decreased quickly after partial hepatectomy. After 7 days the glycogen level was normalized and fructose 2,6-bisphosphate concentration still remained low. The 'active' (non-phosphorylated) form of 6-phosphofructo-2-kinase varied in parallel with fructose 2,6-bisphosphate levels, whereas the 'total' activity of the enzyme decreased only...

G(M), the muscle-specific glycogen-targeting subunit of protein phosphatase 1 (PP1) targeted to the sarcoplasmic reticulum, was proposed to regulate recovery of glycogen in exercised muscle, whereas mutation truncation of its COOH-terminal domain is known to be associated with type 2 diabetes. Here, we demonstrate differential effects of G(M) overexpression in human muscle cells according to gl...

A 75-year-old man without overt heart failure showed an abnormally high level of brain natriuretic peptide (BNP) in plasma: 600 pg/ml. The left ventricular endomyocardial biopsy revealed prominent vacuolar degeneration in the myocytes, most of which were positive for PAS stain and BNP immunoreaction. Ultrastructurally, degenerative changes of myocytes were marked, such as deposits of glycogen a...

Evidence for active glycogen metabolism in normal mature red blood cells (RBC) is presented. Initial rates of ‘4C-U-glucose incorporation into erythrocyte glycogen were found to be independent of substrate concentration over a range of 3.3-16.6 mM. Incorporation of label into glycogen was initially linear but reached a plateau after a variable period of time that was Inversely related to RBC co...
