We conducted a comparative analysis of biochemical parameters for the ascorbate-glutathione cycle in non-transgenic and transgenic Nicotiana tabacum, plants cultivated heavy metal polluted soils. Transgenic had their genome bacterial acdS-gene encoding 1-aminocyclopropane-1-carboxylate deaminase (ACC-deaminase) enzyme. The introduction elevated concentrations copper, chromium, lead ions into so...

The synthesis of four novel platinum complexes, bearing N6-(6-amino-hexyl)adenosine or a 1,6-di(adenosin-N6-yl)-hexane respectively, as ligands of mono-functional cisplatin or monochloro(ethylendiamine)platinum(II), is reported. The chemistry exploits the high affinity of the charged platinum centres towards the N7 position of the adenosine base system and a primary amine of an alkyl chain inst...

Description Creatine is a naturally occurring amin (~1 g/day-1 [~0.04 oz.]) occurs in the glycine, arginine, and methionine. Cr daily requirement of ~2 to 3 g [~0.1 o Approximately 3 to 5 g [~0.1 to 0.2 o uncooked meat or fish. Dietary creat enters the bloodstream. Most (95 pe muscle. Sixty to seventy percent of s phosphocreatine (PCr), which is effe the anaerobic production of adenosin g [~4 o...

Background: Many plant growth-promoting bacteria including Rhizobia contain the 1-aminocyclopropane-1-carboxylate (ACC) deaminase enzyme that can leave ACC, and thereby lower the level of ethylene in stressed plants. Drought and salinity are the most common environmental stress factors for plants in Iran. Objectives: The main aim of this research was development of bio-fertilizers containing A...

background and objective: brucellosis is a main transmittable zoonotic disease, which is endemic, and a common health burden in iran. adenosine deaminase (ada) is an essential enzyme which is involved in purine metabolism and its role in immune system is very important. the aim of this study was to determine serum changes of ada and c-reactive protein (crp) levels in patients with brucellosis. ...

A cell-free extract of Escherichia coli was induced by DNAs, prepared from various bacteriophages, to synthesize deoxycytidylate deaminase in vitro. With T4 DNA, only low levels of dCMP deaminase were synthesized. However, DNAs from two Bacillus subtilis bacteriophages, SP82 and SPSC, furnished very active templates for dCMP deaminase synthesis in the E. coli system. Each of these phages induce...

The synthesis and design using molecular modeling techniques for non-peptide, low molecular weight novel fibrinogen receptor (glycoprotein IIb/IIIa: Gp IIb/IIIa) antagonists, is reported. We used a highly potent serine protease inhibitor, Nafamostat, having an amidinonaphthyl unit as the starting compound. The compounds 4-(6-amidino-2-naphthylaminocarbonyl)phenoxyacetic acid (5a) and 4-(6-amidi...

background in spite of recent advents, and novel improvements in the diagnosis and treatment of pulmonary tuberculosis (tb), definitive diagnosis of pulmonary tb in children is problematic. therefore, measurement of the serum level of adenosine deaminase (ada) was later introduced as a helpful marker for the diagnosis of tb. objectives the purpose of this study was to determine the usefulness o...

The objective of this work was to isolate cultured mouse cells with amplified adenosine deaminase genes. Such cell lines should be very useful in an effort to obtain the protein and nucleic acid probes required to study adenosine deaminase gene structure and regulation. Since adenosine deaminase expression is not required for growth of cells in culture, the first step necessary to isolate adeno...
