A sensitive, specific, reproducible and optimized high performance liquid chromatography with fluorescence detection (HPLC-FLD) method for the determination of bergapten in rat plasma was established and applied to the pharmacokinetic and bioavailability study in rat after oral and intravenous administration of bergapten. The method was also successfully applied to the excretion study of bergap...

purpose: to evaluate total plasma homocysteine level during the acute phase of central retinal vein occlusion (crvo) compared with a matched healthy group in iranian population, and determine whether hyperhomocysteinemia is also a risk factor for crvo. methods: a study group contains 54 patients presenting with crvo in recent one month, acute phase of the decease, was compared for fasting total...

background : doogh is a fermented beverage in which microbial spoilage is possible. benzoic acid and its salt (sodium benzoate) are added to doogh as antimicrobial preservative to control microbial spoilage. however, the use of this preservative has been prohibited in milk and dairy products such as food and drug administrationand institute of standards and industrial research of iran. thus, th...

Convenient drug-resistance testing of viral mutants is indispensable to effective treatment of viral infection. We developed a novel fluorometric assay for phenotypic differentiation of drug-resistant mutants of human immunodeficiency virus-I protease (HIV-PR) which uses enzymatic and peptide-specific fluorescence (FL) reactions and high-performance liquid chromatography (HPLC) of three HIV-PR ...

Amino acids are involved in various chemical reactions vivo, and changes several amino urine related to certain disease states. Therefore, developing an efficient method analyze the is useful timely diagnosis of diseases. In this study, we developed a high-performance liquid chromatography (HPLC) fluorescence for quantitative analysis urinary using derivatization reagent 2,3-naphthalenedicarbox...
