a new anti-corrosion compound, melamine formaldehyde (mf), was formulated by the addition of proper amount of formaldehyde to melamine under specific conditions. this compound was mixed with a novel nano powder, which was extracted from corn cob ash containing sio2 particles, in order to improve its corrosion inhibition efficiency. this inhibitor provides a high level of protection for steel su...
background: hemophilia is the most frequent severe hereditary hemorrhagic disease due to deficiency of coagulation factors viii (hemophilia a) or ix (hemophilia b) in plasma. we aimed to identify patients with hemophilia in kermanshah, iran and assess the incidence of inhibitors in this population and its associated factors. methods: this study was conducted on patients with hemophilia a and b ...
Abstract Background and Objective: Highly Active Antiretroviral Therapy (HAART) can effectively prevent the progression of HIV-1 replication and increase life expectancy. There are numerous causes of treatment failure and the leading one is drug resistance. Thus, we aimed to determine the HIV RT gene drug resistance mutations in patients treated with antiretroviral medications. Material...
Background: The development of inhibitors is a complication factor replacement therapy in hereditary factor VIII deficiency. Several management options are available for the treatment of inhibitor. Rituximab, a monoclonal antibody against CD20, reduces inhibitor level in rare bleeding disorders. The aim of this study was to evaluate the effectiveness of rituximab in lowering or eliminating the ...
مطالعات انجام شده روی مکانیسمهای تکوینی و تکاملی گلبولهای قرمز منجر به دستیابی بشر به مفاهیم پایه و مهمی در ارتباط با مکانیسمهای عمومی تنظیم بیان ژن وشکل گیری بافتها شده است. تمایز اختصاصی به رده ارتیروئید و هر رده دیگری، شدیداً وابسته به تنظیم در سطح بیان ژن و فاکتورهای کنترلی خاص نظیر سیتوکین ها، فاکتورهای نسخه برداری ویژه، عناصر کنترل کننده چرخه سلولی، تکثیر،آپوپتوز و عناصر سیگنالینگ داخل سلو...
In this research, mesoporous silica was applied as the host of corrosion inhibitor (molybdate). The loaded mesoporous silica was dispersed in an epoxy matrix. The composite was then coated on the mild steel plate. Results showed that the corrosion resistance of the scratched epoxy/mesoporous silica loaded by molybdate was better than the one without molybdate or neat epoxy. On the other hand, E...
In this study, an organic compound inhibitor, namely N-benzyl-N-(4-chlorophenyl)-1H-tetrazole-5-amine (NBTA), was synthesized and the role of this inhibitor for corrosion protection of stainless steel (SS) exposed to 0.5 M H2SO4 was investigated using electrochemical, and quantum analysis. By taking advantage of potentiodynamic polarization, the inhibitory action of NBTA was found t...
The corrosion behavior of mild steel (Ck 45) in 3.0 M H3PO4 solution in the absence and presence of penicillin G was studied using potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) techniques. The best inhibition effect at 10 mM of drug was a marked characteristic of the inhibitor. It was found that the inhibition efficiency of the inhibitor...
In this paper, the effect of penicillin G drug as a green corrosion inhibitor on mild steel in 1.0 Mhydrochloric acid solution has been investigated using potentiodynamic polarization, electrochemicalimpedance spectroscopy (EIS) and electrochemical noise (EN) techniques. The inhibition efficiencywas found to increase with increasing inhibitor concentration. Potentiodynamic polarizationmeasureme...
Derivatives of phenyl-keto butenoic acids have been reported to be inhibitors of pyruvate decarboxylase, (PDC). The inhibition of transketolase, a thiamine requiring enzyme such as PDF, by meta nitrophenyl derivative of 2-oxo-3-butenoic acid (MNPB) is reported here. These studies indicate that the inhibitor binds to the enzyme at the active site. A two-step inhibition was observed, first th...
