Abstract The purpose of this study was to solve the chloride corrosion damage problems rebar in reinforced concrete structures under environment. effects 1.0% triethanolamine (abbreviated as TEA), Ca(NO 2 ) , and 0.5% TEA + composite inhibitor) on electrochemical performance modification mechanism mortar specimens were investigated by combining macro experiment microanalysis. results showed tha...
A tin-containing metallic complex derived from Curcuma longa, bis[1,7-bis(4-hydroxy-3-methoxyphenyl)-1,6-heptadiene-3,5-dionato-?O,?O ? ]bis(butyl), has been obtained and used as a green corrosion inhibitor for carbon steel in 0.5 M sulfuric acid by using weight loss, electrochemica...
To address rebar corrosion in existing concrete structures, a multifunctional compound rust inhibitor was developed. This study investigates the impact of this on carbon steel resistance, as well mechanical properties and durability concrete. The results demonstrate significant reduction weight loss when using inhibitor, with inhibition efficiency 82.6%. Scanning electron microscopy (SEM) atomi...
Abstract Ethanol has a vast consumption around the world. Many researches confirmed some adverse effect of this component on human health. In addition, recent studies showed significant alteration in both cellular population, and protein profile of human foreskin fibroblast cell line (HFFF2) in the specific dosage of ethanol. Here, the role and interaction of some proteins (characterized by sig...
SRC kinases and PKR are intracellular protein kinases, which play key roles in intracellular viral replication. In this research, the effect of SRC kinase inhibition and PKR activation and inhibition on replication of coxsakievirus (CVB3), an entrovirus of the family picornaviridae – causative agents of fatal myocarditis, was studied. Vero and Hela cells were cultured and infected with CVB3 in ...
Introduction: Many factors cause cognitive impairment, including medication, such as selective serotonine reuptake inhibitor drugs use. On the other hand, many drugs are used in cognitive impairment therapy, including donepezil, which act by inhibiting the cholinesterase enzyme and increase brain acetylcholine. Methods: This study was a double-blind controlled randomized controlled clinical tr...
The present study is a case report of patient with diagnosis renal cell carcinoma poor prospects, in whom long-term tumor control at the level deep cytoreduction was achieved through aggressive multidisciplinary management using surgery, stereotactic radiotherapy, and sequential systemic therapy immunotherapy based on checkpoint inhibitor anti-PDL1 activity combined anti-angiogenic treatment, b...
Objective(s): Myocarditis is characterized by inflammatory cell infiltration in myocardial stroma. Attenuation of tumor necrosis factor (TNF)-α and interleukin (IL)-1β is a reliable mark for improving the prognosis. Protein kinase B (Akt) plays an important role in the development and progression of myocarditis. The specific role of the natural inhibitor of Akt, Deguel...
Effectiveness of furfural as an organic inhibitor in 5 percent hydrochloric acid which is used in acid pickling of steel was evaluated. Lungmuir, Frumkin and Flory-Huggins isotherms [1, 2] were used to determine the parameters of effective adsorption, free energy and entropy of adsorption. Furfural indicated an inhibition less than 17 percent in concentrations of 0.001 mole per liter for a dura...
