The tissue content of energy-rich phosphates and glycolytic metabolites and the activity of myocardial enzymes were examined in the dog after producing myocardial infarction by ligating branches of the anterior descending and circumflex coronary arteries. The pattern of systolic fiber movement shown by a strain-gauge assembly differentiated ischemic from nonischemic portions of myocardium. In i...

Some tissues contain more than one enzyme exhibiting 'acid-phosphatase' action and the partial separation of such enzymes has been reported, e.g. from rat liver (Goodlad & Mills, 1957; Barka, 1961 a, b) and from Escherichia coli (Rogers & Reithel, 1960). Among the factors that make the interpretation of experimental observations on 'acid-phosphatase activity' difficult are (a) in the earlier wo...

OBJECTIVE Remineralization is an effective treatment that may stop or reverse early tooth decay. Grape seed extract (GSE) is the potential remineralizing agent under investigation. MATERIALS AND METHODS Sound human tooth sections were obtained from the cervical portion of the root and stored in demineralizing solution at 37°C for 96 hours to induce artificial root caries lesions. The sections...

L-alpha-glycerophosphate oxidase (GlpO) plays a central role in virulence of Mycoplasma mycoides subsp. mycoides SC, a severe bacterial pathogen causing contagious bovine pleuropneumonia (CBPP). It is involved in production and translocation of toxic H(2)O(2) into the host cell, causing inflammation and cell death. The binding site on GlpO for the cofactor flavin adenine dinucleotide (FAD) has ...

1. Abstract. All the living organisms are classified into three domains (the newly proposed highest rank of classification of organisms). Escherichia coli and Bacillus subtilis are belonging to one of the domains, Bacteria. Works on the two bacteria made a great deal of contribution to construct modern microbiology, new concept of biochemistry and molecular biology. Compared with research histo...

Lipolysis of triglycerides goes on constantly in adipose tissue producing glycerol and free fatty acids. The fatty acids can be activated and reesterified. Glycerol, on the other hand, is not metabolized to any significant extent (1-3). Glycerokinase, the enzyme that catalyzes the formation of a-glycerophosphate from glycerol and adenosine triphosphate, is apparently absent and glycerol is not ...
