The term ‘protein’ is derived from the Greek word ‘Proteios’ meaning primary and is therefore well chosen, since proteins the first recognizable and distinctive expression of genetic information. The structure of proteins enable them to act as the catalysts which control the rates of all biological reactions, to serve as the carriers essential substances within the organisms, to serve as regula...

Abstract Contemporary medicine applies the analysis of molecular composition and physicochemical properties biological fluids as one main tools for diagnostics control over body state behaviour pathological processes. However, most laboratory methods (such biochemical, enzyme-linked immunosorbent assay, etc.) are too expensive time-consuming. They demand availability well-equipped laboratories,...

This article discusses the various mechanisms, biochemical pathways, and chemical substances involved in neuronal cell death and cell survival, in an attempt to put an order to the sequence of events that ultimately lead to a commitment to neurological cell death. An understanding of these pathways is crucial to discovering etiologies involved in the pathologic changes that occur in patients wi...

Liver injury, and frequent consequent fibrosis, is the focus of a number of research groups ranging from molecular biologists to clinicians. It encompasses many aspects and approaches. Among biochemical events the role of Kupffer cells, oxidative stress and pro-inflammatory mediators are eminent. In this review we focus on recent findings into use of natural substances for the modulation of oxi...

A clinical, biochemical, and pathological study is recorded of 50 patients in whom a diagnosis of idiopathic steatorrhea had been made and who had ;flat' jejunal biopsies. It is suggested that there is an underlying constitutional defect, not yet clearly defined, and that possibly secondary intestinal infection allows the intestinal mucosa to become sensitized to substances in the diet. Of thes...

OBJECTIVES To evaluate an increase in plasma concentration of thiobarbituric acid reactive substances as a non-invasive biochemical test of reperfusion after thrombolysis and to investigate the relation between the inflammatory response after acute myocardial infarction and the production of the substances. METHODS Venous samples were taken from 19 patients receiving thrombolysis for acute my...

The literature relating to the histochem­ istry of the periodontal tissues is reviewed. The distribution of alkaline and acid phosphatase, mucopolysaccharides and glycogen, metachromatic substances, and the disulfide and sulfhydryl groups is described, and their probable role in the histophysiology of the periodontium is analyzed. Histochemical research may lead to a better understanding of the...
