The aim of the current study is to evaluate the effects of inhibitors or solvents on asphaltene precipitation under reservoir conditions. To this end, the interaction between live oil and solvent, and its side effects on precipitated/dissolved asphaltene were predicted via Miller’s entropy modified polymer solution theory under reservoir conditions. Then, the adjustable parameters of the model ...

experimental acute gastric ulcer is produced by the intraperitoneal injection of a single dose of indomethacin. acetazoleamide, a potent carbonic anhydrase inhibitor, has significantly prevented the occurrence of these ulcers. its probable mechanism is discussed.

background: neutrophils have an important role in the rapid innate immune response, and the release or active secretion of elastase from neutrophils is linked to various inflammatory responses. purpose of this study was to determine how the human neutrophil elastase affects the interleukin-10 (il-10) response in peripheral blood mononuclear cells (pbmc). materials and methods: in this prospecti...

In retinal organ cultures, H2O2 can be used to simulate oxidative stress, which plays a role in the development of several diseases including glaucoma. We investigated whether processes underlying stress prevented cultures by an inducible nitric oxide synthase (iNOS)-inhibitor. To this end, porcine explants were cultivated for four and eight days. Oxidative was induced via 300 µM on day one thr...

A study has been carried out to evaluate the effect of expired Esomeprazole (S3O3N19H17C) (20mg) as Inhibitor on corrosion behaviour carbon steel in desalination water (Drinking water) by using weight loss technique at room temperature. The test solution used this was Desalination samples and Inhibitor. Langelier Saturation Index (LSI) results potential pH diagram (Pourbaix diagram) gave an ind...

This study aims to determine the corrosion rate steel using an inhibitor kepok banana peel extraction with various immersion media. Sample time is 168, 336, 504 hours. The method used calculate measure weight loss. sample this research was carried out Mechanical Engineering laboratory, Facult...

onion (allium cepa) contains high levels of flavonoids. although there are many studies indicating the inhibitory effects of flavonoids on xanthine oxidase, there is no report on the effect of onion on this enzyme. therefore, in the present study, the inhibitory effects of onion on xanthine oxidase are investigated. fresh filtered juice of onion was prepared and its inhibitory effect on guinea ...

We hereby develop the theory of Turing instability for reaction-diffusion systems defined on complex networks assuming finite propagation. Extending to networked framework introduced by Cattaneo in 40's, we remove unphysical assumption infinite propagation velocity holding systems, thus allowing propose a novel view fine tuning issue and existing experiments. analytically prove that instability...

In this study, an agricultural waste product was used to prepare a green corrosion inhibitor based on olive leaves (Olea europaea var. syslvestris). Firstly, optimization study of antioxidant activity O. monitored by the DPPH free radical trapping method, carried out using full factorial design. second step, extract obtained under optimal conditions tested as for steel in 0.5 mol dm-3 HCl, grav...

conclusions the authors describe the second reported case of eptifibatide-induced severe thrombocytopenia associated with cardiac surgery. in this case, discontinuation of eptifibatide and transfusion of apheresis platelets increased the platelet count (137 k/ul) the following day, and the patient subsequently underwent successful coronary artery surgery using cardiopulmonary bypass. introducti...
