Chromatographic and immunological evidence is presented regarding the hydrolysis of the ester linkage of O2'-monosuccinyl cyclic AMP in neutral solutions. Such hydrolysis occurs whether the nucleotide derivative is present in free form in solution or conjugated through its succinyl carboxyl group via an amide bond to proteins. The latter process apparently occurs when succinyl cyclic AMP is con...

Endocarditis is a rare but serious manifestation of Listeria monocytogenes (LM). However, the optimal treatment strategy for LM endocarditis has yet to be established. Current antibiotic strategies for listeriosis include penicillin G or ampicillin (AMP) monotherapy, or AMP + gentamicin combination therapy which is often favored for endocarditis. The primary objective of our investigation was t...

Adenosine 3':5' -monophosphate (cyclic AMP) -dependent protein kinase from bovine heart muscle catalyzes the phosphorylation of its regulatory, cyclic AMP-binding subunit. Phosphorylation enhances net dissociation of the enzyme by cyclic AMP. Chromatography on omega-aminohexyl-agarose was used to study the effects of phosphorylation on cyclic AMP binding and subunit dissociation and reassociati...

Abstract. Thermokarst lakes play an important role in permafrost environments by warming and insulating the underlying permafrost. As a result, thaw bulbs of unfrozen ground (taliks) are formed. Since these taliks remain perennially thawed, they zones increased degradation where microbial activity geochemical processes can lead to greenhouse gas emissions from thermokarst lakes. It is not well ...

Abstract. The atmospheric multiphase reaction of dinitrogen pentoxide (N2O5) with chloride-containing aerosol particles produces nitryl chloride (ClNO2), which has been observed across the globe. photolysis ClNO2 chlorine radicals and nitrogen dioxide (NO2), alter pollutant fates air quality. However, effects local meteorology on near-surface production are not yet well understood, as most obse...

A set of borophosphate glasses doped with alkali and transition metal (TM) ions have been synthesized. The were carried through; annealing, XRD, density, DC conductivity studies. Molar volume density varied nonlinearly. High temperature activation energy is analysed taking into consideration Mott’s SPH model. low electrical was by Mott Greaves VRH. Several polaron hopping related parameters at ...

Dallol Maouri is one of the fossil valleys on left bank Niger River. Its watershed drains water from in Tahoua and Dosso regions Niger. The watercourse not continuous has areas surface accumulation (ponds) spreading infiltration. potential this area limited, with most ponds having a temporary to semi-permanent regime. Groundwater resources are, therefore, main sources withdrawal for human food,...

The renal extracellular 2',3'-cAMP-adenosine and 3',5'-cAMP-adenosine pathways (extracellular cAMPs→AMPs→adenosine) may contribute to renal adenosine production. Because mouse kidneys provide opportunities to investigate renal adenosine production in genetically modified kidneys, it is important to determine whether mouse kidneys express these cAMP-adenosine pathways. We administered (renal art...

This paper aims to contribute the current debates about role of religion in political process, and its importance for creation cohesion different national communities’ identities. It will analyse discussions occurred around concepts, conceptions, Nation, National Community (qaum), Religious (millat), Believers (umma), exploring different, sometimes opposing, ideas doctrines...
