The cardiovascular and acid-base changes following equivalent i.v. bolus doses of sodium nitroprusside (SNP) and potassium cyanide (KCN) have been studied in two groups of anaesthetized dogs. In a third group, the metabolic changes produced by i.v. infusion of SNP 1.5 mg kg-1 at a constant rate over 1 h have been studied. In contrast to a decrease in arterial pressure following SNP, hypertensio...
Disrupted cells of Bdellovibrio bacteriovorus exhibited adenosine triphosphatase activity, 60 to 80% of which was in the soluble fraction. Dicyclohexylcarbodiimide did not inhibit the adenosine triphosphatase activity in membrane particles. The particles did not show energy-linked transhydrogenase activity. The activity of non-energy-linked transhydrogenase as well as the rate of oxygen consump...
Background: Besides acute lethal cyanide poisoning, its chronic intoxication may also produce some pathologic effects on different tissues that precedes alterations in biochemical parameters. The present study was aimed to evaluate the effects of sublethal cyanide exposure on some tissue enzyme activities in liver and kidney of rats. Methods: Twelve male rats were divided into two groups as ...
Nitrilases have a high potential for application in organic chemistry, environmental technology, and analytics. However, their industrial uses require that they are produced highly active robust forms at reasonable cost. Some syntheses catalyzed by nitrilases already reached level of technological readiness. This has been enabled the large-scale production recombinant catalysts. Despite some pr...
MicrosoftInternetExplorer4 Background and Objectives: Cyanide is a toxic pollutant existing in the various industrial effluents such as iron and steel, coal mining, non-ferrous metals manufacturing and metal plating. Its presence in water resources and wastewater, as serious hazardous substances leads to undesirable effects on both the environment and human. Thus, its concentration control...
Background and purpose: Dyes and cyanide are the most important sources of environmental pollution, found in industrial wastewater, which are harmful for human health and environment. The purpose of this research was to investigate the Kinetic and efficiency of titanium dioxide photacatalytic process in removal of Reactive Black 5 (RB5) dye and cyanide from aquatic solution in a batch system....
The measurement of blood cyanide is of clinical importance because, aside from the relatively few cases of accidental or selfinduced poisoning, raised levels are found in patients receMng the hypotensive agent sodium nitroprusside (1), in victims of smoke inhalation injury (2), and in lx~pulations at risk of ataxic mydopathy in areas of high cassava consumption C,). However, very few hospital l...
a major concern in the last few years has been the fact that the cultural centers are keeping distance with what they have been established for and instead of reproducing the hegemony, they have turned into a place for resistance and reproduction of resistance against hegemony. because the cultural centers, as urban public spaces in the last two decades, have been the subject of ideological dis...
The cellular oxygen sensor is a family of oxygen-dependent proline hydroxylase domain (PHD)-containing enzymes, whose reduction of activity initiate a hypoxic signal cascade. In these studies, prolyl hydroxylase inhibitors (PHIs) were used to activate the PHD-signaling pathway in cardiomyocytes. PHI-pretreatment led to the accumulation of glycogen and an increased maintenance of ATP levels in g...
