Intervertebral disc degeneration (IDD) is a chronic, complex process associated with low back pain; mechanisms of its occurrence have not yet been fully elucidated. Its process is not only accompanied by morphological changes, but also by systematic changes in its histological and biochemical properties. Many cellular and molecular mechanisms have been reported to be related with IDD and to rev...

The present investigation was carried out about the corrosion inhibition and adsorption behavior of Neem and Hibiscus, as a green inhibitor of Zinc corrosion in acidic mediated of corrosion causing soil microbes by using weight loss and thermodynamic studies. Even analyze the quantitatively and qualitatively biochemical substances present in Neem and Hibiscus leaves of aqueous and ethanol extra...

Transport of substances and communication between compartments are fundamental biological processes, often mediated by the presence of complementary proteins attached to the surfaces of membranes. Within compartments, substances are acted upon by local biochemical rules. Inspired by this behaviour we present a model based on Membrane Systems, with objects attached to the sides of the membranes ...

Alcoholic beverages contain not only alcohol but also numerous other substances (i.e., congeners) that may contribute to the beverages' physiological effects. Plants used to produce alcoholic beverages contain estrogenlike substances (i.e., phytoestrogens). Observations that men with alcoholic cirrhosis often show testicular failure and symptoms of feminization have suggested that alcoholic bev...

Rhodnius prolixus is a Hemiptera that feeds exclusively on vertebrate blood in all life stages. Its salivary glands produce potent pharmacological substances that counteract host hemostasis, including anti-clotting, anti-platelet, and vasodilatory substances. To obtain a further insight into the salivary biochemical and pharmacological complexity of this insect, a cDNA library was randomly sequ...

The aim of this study was to assess the temporal patterns of (the formation of) thiobarbituric acid reactive substances and the activities of antioxidant enzymes in the erythrocytes of ten healthy adult subjects and ten oral cancer patients of comparable age. The levels of thiobarbituric acid reactive substances and the activities of antioxidant enzymes were assayed at 6-hour intervals using co...

we evaluated the efficacy of a full-scale combined biophysicochemical system for treatingmolasses-based bioethanol wastewater in terms of organic substances, nutrient, and dark brown color removal. the main organic removal unit, i.e., the upflow anaerobic sludge blanket (uasb) reactor, achieved 80.7% removal and 4.3 nm3 methane production per cubic meter of wastewater with a hydraulic retention...

This paper analyzes the ontological requirements for representing biology knowledge, and identifies several areas where current knowledge representation (KR) paradigms need to be extended. We focus on the representation of experimental materials and methods, and the reasoning task of intelligent information retrieval; however, the ontological issues we raise apply to biology (and experimental s...

Bioregulators or modulators are biochemical compounds such as peptides, that occur naturally in organisms. Advances in biotechnology create the potential for the misuse of peptide bioregulators in offensive biological weapons programmes. Bioregulators are a new class of weapons that can damage the nervous system, alter mood, trigger psychological changes and kill. Over the last twenty years, ne...

The energy charge potential of the cerebral adenylate system, the cerebral lactate: pyruvate system, and the cerebral glycogen level were used to characterize the cerebral energy state of the brain. Cerebral adenyl cyclase activity and cyclic AMP concentrations were investigated to evaluate their possible influence on the regulatory processes in brain metabolism. These biochemical parameters we...
