Lipid peroxidation (LPO), an oxidative chain reaction often occurring in the human body and food, is harmful to health. Due its convenience low cost, this guideline highlights benefits drawbacks of LPO models by spectrophotometer vitro vivo. The preparation process mechanism lipid substrates, oxidation triggers detection methods are discussed paper better screen antioxidants. substrates mostly ...

A simple, rapid and precise method that does not involve digestion has been described for determination of plant K. The method involves shaking of 0.5 g of finely ground plant materials with 40 ml of 0.5 N_ HC1 for 5 minutes. The extract is filtered and read in an Atomic absorption spectrophotometer for K. The method gives !< values that are in close agreement with those obtained with conventio...

Introduction The rate of an enzyme reaction varies with substrate concentration; therefore this can be used to determine the amount of substrate present. Measurement of such a reaction requires the determination of the amount of product produced or the disappearance of substrate consumed. With many assays this cannot always be done directly, therefore the reaction may be coupled to a second enz...

INTRODUCTION The aim of the present study was to investigate whether the concentration of arsenic (As) released from gray or white mineral trioxide aggregates (MTAs) met the requirement of the International Standards Organization (ISO) for dental cements. METHODS Sample preparations were carried out according to the ISO methods. After centrifugation of dissolved samples, As (III) concentratio...

Abstract Background In TB, therapeutic drug monitoring (TDM) is recommended for linezolid; however, implementation challenging in endemic settings. Non-invasive saliva sampling using a mobile assay would increase the feasibility of TDM. Objectives To validate linezolid UV spectrophotometer. Methods The was developed NanoPhotometer NP80® and concentrations were quantified second-order derivative...

The high quality thin films of (CdS)0.6 Se0.4 have been synthesized using thermal evaporation technique onto precleaned rotating amorphous glass substrate at room temperature. The films were characterized by X-Ray Diffractometer, Scanning Electron Microscopy, Atomic Force Microscopy and UV-VIS Spectrophotometer. The XRD spectrum illustrates that the films are polycrystalline having hexagonal st...
