RATIONALE Decreased alkaline phosphatase activity after infant cardiac surgery is associated with increased post-operative cardiovascular support requirements. In adults undergoing coronary artery bypass grafting, alkaline phosphatase infusion may reduce inflammation. Mechanisms underlying these effects have not been explored but may include decreased conversion of extracellular adenine nucleot...

The phosphorylation of nucleosides (adenosine, guanosine, cytidine, and uridine) and nucleotides (adenosine 5'-monophosphate, guanosine 5'-monophosphate, cytidine 5'-monophosphate and uridine 5'-monophosphate) has been achieved using inorganic monoimido-cyclo-triphosphate (MCTP, Na(3)P(3)O(8)NH) in aqueous solution. In this reaction, the 2'-OH or 3'-OH group of the beta-D-ribofuranose unit was ...

To investigate the role of gallic acid in lipopolysaccharide/interferon-gamma induced macrophage polarization toward M1. Macrophages were isolated from peritoneal wash fluid and exposed to prepared at concentrations control, 6.25, 12.5, 25 37.5 μg/ml, presence lipopolysaccharide interferon-gamma, for establishment M1 polarization. Adenosine 5’-monophosphate-activated protein kinase inhibitor co...

The adenyl cyclase and phosphodiesterase metabolizing adenosine 3',5'-cyclic monophosphate (cyclic AMP) were detected in mycelia of strains of Coprinus macrorhizus which form fruiting bodies, but not in those of strains which do not form fruiting bodies. The adenyl cyclase synthesized cyclic AMP from adenosine triphosphate. The phosphodiesterase degr[UNK]ded cyclic AMP to adenosine-5'-monophosp...

Spectroscopic properties of 1, N6-ethenoadenosine cyclic 3', 5'-monophosphate were studied and compared with cyclic adenosine 3', 5'-monophosphate. Date of nuclear magnetic resonance-, mass-, ultraviolet-, and fluorescence spectroscopy were given. Additionally biochemical activity was tested in protein kinase system of beef adrenals. No significant biological difference between cyclic adenosine...

In Klebsiella aerogenes P-galactosidase and histidase are subject to strong catabolite repression by glucose in the presence of a good source of nitrogen. Under conditions of nitrogen limitation, the catabolite repression of histidase is relieved, while fi-galactosidase remains strongly repressed. Exogenous adenosine 3’, 5’-monophosphate relieves the catabolite repression of both histidase and ...

background: the purpose of this study is to evaluate effects of teucrium polium (tp) leaf extracts on adenosine monophosphate activated protein kinase (ampk) level in isolated pancreases. materials and methods: in this experimental study, two groups of rats were used as a control group, and diabetic group. in the end of experimental period the animals were sacrificed then pancreas were removed,...

The development of the luminescence system in Beneckea harveyi is controlled by cyclic nucleotides at the level of transcription. In the wild type, it is repressed by exogenously added guanosine 3':5'-cyclic monophosphate and this repression is overcome by the addition of adenosine 3':5'-cyclic monophosphate. These observations alone support a model in which these nucleotides act antagonistical...
