The goal of this paper is to present new experimental results obtained during the study of the gas phase oxidation of ethyl-benzene, n-hexyl-benzene, ethyl-cyclohexane and n-butyl-cyclohexane which belongs to two molecule families present in diesel fuels: alkylbenzenes and alkylcyclohexanes. Experiments were carried out in a jet-stirred reactor over the temperature range 550–1100 K. The new res...

Objective: The purpose of this study is provide an historical arbitrary. The later models, however, assume that the nature context for current behavioral models of hypertension. Methof the eliciting stimulus is a determinant of the cardiovascular ods: A selective sample of the cardiovascular reactivity literaresponse. We describe the increasing complexity of the four ture was reviewed, from 193...

Elucidating chemical reactivity in complex molecular assemblies of a few hundred atoms is, despite the remarkable progress in quantum chemistry, still a major challenge. Black-box search methods to find intermediates and transition-state structures might fail in such situations because of the high-dimensionality of the potential energy surface. Here, we propose the concept of interactive chemic...

abstract cisplatin was the first of the platinum drugs. second-generation platinum derivative was carboplatin that its efficacy in the treatment of many malignancies is equal to cisplatin, and its toxicity profile is more favorable. here we report on a 50-year-old woman with a history of cervix cancer who developed a severe hypersensitivity reaction (hsr) to carboplatin. she was admitted to the...

the present work reports the detailed b3lyp/6-311++g(d,p) study of most stable transand cisconfigurations photoisomerization in the core system of computational photochemistry-the 5,5'-disubstituted-1,1'-azobis (tetrazole) molecules. all computations were carried out in gas phase attemperature 293.15 k and pressure 1 atm. firstly; the potential energy surface (pes) of the groundstate ...

angiotensin-converting enzyme (ace) inhibitors appear to correct many of the abnormalities associated with the vascular dysfunction found in diabetic patients. in this respect, quinapril is a unique ace inhibitor with multiple protective effects. the present study was carried out to investigate the effect of intraperitoneal administration of quinapril on the aortic reactivity of streptozotocin ...

we report herein the development of a highly sensitive colorimetric method for the detection of 4-hydroxy-2-mercapto-6-methylpyrimidine (mtu) which acts as an anti-thyroid drug utilizing citrate capped gold nanoparticles (au-nps). this thiol-containing molecule exhibits intriguing affinity with au-nps. the reactivity involves the displacement of the citrate shell by the thiolate shell followed ...

objective(s) the aim of this study was to evaluate the expressions of two angiogenic immune-markers (cd-31 and vegf), and one proliferative immune-marker (ki-67) in oral pyogenic granulomas (pg), hemangiomas (hem) and inflammatory gingivitis (ig). materials and methods sixty cases of pg, hem and ig (twenty cases each) were examined. immunohistochemical (ihc) staining was performed based on rout...

the objective of this study was to compare different antigen preparations to produce monoclonalantibodies against bovine leukaemia virus gp51su. the four antigen preparations for immunization ofbalb/c mice were: cl: blv-flk cell lysate, uf: a fraction of cl (between 30 and 100 kda), wvp: wholevirus particles and sp: with ion exchange chromatography, gp51su was semipurified. a total of ninesucce...

BACKGROUND Plasma concentrations of asymmetric dimethylarginine (ADMA), an endogenous inhibitor of nitric oxide synthase, are raised in patients with chronic vascular disease, causing increased cardiovascular risk and endothelial dysfunction, but the role of ADMA in acute inflammatory states is less well defined. METHODS AND RESULTS In a prospective longitudinal study in 67 patients with acut...
