Since active pharmaceutical ingredients (APIs) are directly related to human health, monitoring and quantifying them in the environment is a crucial challenging issue. Using capillary-zone electrophoresis (CZE), four frequently used fluoroquinolones (FQs), ciprofloxacin, sparfloxacin, moxifloxacin, gatifloxacin, were efficiently isolated measured industrial wastewater. Solid-phase extraction (S...

Background: Meat products may be unacceptably tough because of the high connective tissue content of meats used in their manufacture. OBJECTIVE: The aim of this study was using meat acid marination method on some physicochemical and sensory characteristics of beef burgers. METHODS: Meat was marinated in three concentrations (0.5%, 1% and 1.5%) of lactic and citric acid solutions (1:4 w/v) at 4 ...

In an ideal electrophoresis of a solution of two components the volumes swept through by the rising and descending boundaries due to each component are identical and are proportional to the mobilities of the separate components. Moreover, the area under each "peak" in the electrophoretic pattern is proportional to the stoichiometric concentration of that component in the mixture to which it is ...

Gene expression analysis by electrophoretic methods is currently limited by the labor-intensive visual evaluation of the electrophoretic signal profiles. For this purpose, we present a flexible approach to computer-assisted comparison of quantitative electrophoretic patterns between multiple expression signals. Gaussian curves are first fitted to the complex peak mixtures, and the resulting app...

IIn this study, the effects of paraxanthin on lettuce were investigated. Paraxanthin is a group of purine alkaloids, secondary metabolites of plants. This compound is made up of the caffeine metabolism found in plants such as tea, coffee and cocoa. There have been previous reports of paraxanthine antihypertensive properties.Three different concentrations of paraxanthine as 10, 50 and 100 µg/ml ...

the aim of the study was to describe the urinary electrophoretic pattern of dogs with heartworm disease.urine samples from 15 heartworm-infected and 15 healthy dogs were taken. urinary specific gravity, urinaryprotein concentration and the urine protein/creatinine (u p/c) ratio were determined. urine proteins werefractionated using sds-page. results showed statistically significant differences ...
