Human arylamine N-acetyltransferase 2 (NAT2) mediates the biotransformation of arylamine drugs and procarcinogens into either innocuous or reactive DNA-damaging metabolites and is expressed predominantly in liver. Interspecies differences and incongruous results between in vitro, in vivo, and epidemiological studies make it difficult to extrapolate animal results to human risk. We have generate...

A highly sensitive and accurate spectrophotometric method including Technique ( Normal Flow injection analysis have been used for determined Nifedipine (NIF) drug in pure dosage forms. This approach based on the response of with diazotized sulfamethoxazole (SMZ) to form colored product after diazotization reagent coupling reaction The coloured chromogen suggests absorption maximum at 496 nm. li...

A convenient method was developed for determination of sulfathiazole (STZ) in Type C medicated swine feed by reversed-phase liquid chromatography (LC) with post-column derivatization. Addition of extractant solution (0.2N HCl and 1.5% diethylamine in 25% methanol) and an internal standard (IS), sulfamethylthiazole (SMZ), to 5 g sample was followed by mechanical shaking for 1 h. The extract was ...

Large volumes of fly ash and other coal combustion products (CCPs) are produced every year by coal-fired power plants. About 50% of the CCPs produced in the U.S. is buried in impoundment lagoons or dry landfills. Fly ash is generally enriched in several potentially hazardous trace elements, such as As, B, Cd, Co, Cr, Mo, Se, Sr, and V, which can leach from older, unlined disposal sites. Therefo...

the electrochemical oxidation of sulfamethazine (smz) has been studied at a multi-walled carbon nanotubes modified glassy carbon electrode (mwcnt-gce) by cyclic voltammetry. this modified electrode (mwcnt-gce) exhibited excellent electrocatalytic behavior toward the oxidation of smz as evidenced by the enhancement of the oxidation peak current and the shift in the anodic potential to less posit...

In this paper we investigate the noise and crosstalk characteristics of all optical router based on SMZ switch using a numerical model. Two effects, the relative intensity noise (RIN) and channel crosstalk (CXT) that degrade the bit error rate (BER) performance of the router are investigated. Numerical simulation results show that for BER of 10, the sensitivity of the receiver with all-optical ...

Abstract Sulfonamide antibiotics like sulfamethazine (SMZ) can threaten aquatic and terrestrial life even in small concentrations (? 1 mg/L); hence, their removal from wastewater is indispensable. However, the need to explore new promising adsorbents that are cheap, effective, reusable also remains crucial developing adsorption technology. This work presents a one-pot solvent-free conversion of...

We determined the ability of two iron-and-zeolite materials to remove arsenic from groundwater. The first material is composed of iron, surfactant-modified zeolite, and hard silicate foam, and is known as Surfactant-Modified Zeolite/ Zero-Valent Iron (SMZ/ZVI). The second material is a new formulation that consists of iron-modified zeolite (IMZ). We prepared eight different prototypes of IMZ fo...

Brain nocardiosis is a serious opportunistic infection with high mortality. It exists more common in the immunocompromised hosts than the immunocompetent patients. Trimethoprim-sulfamethoxazole (TMP-SMZ) has been mostly considered as the choice of the medical treatment. Linezolid is also newly found to be effective to avoid the invasive surgery. The authors reported a case of patient with multi...
