An improved method for measuring catalase activity in biological samples.

Catalase (CAT) is an important enzyme that protects biomolecules against oxidative damage by breaking down hydrogen peroxide (HO) into water and oxygen. CAT is present in all aerobic microbes, animals, and plants. It is, however, absent from normal human urine but can be detected in pathological urine.

Novel fluorometric protocol for assessing myeloperoxidase activity.

Neutrophil myeloperoxidase (MPO) is an essential enzyme for the innate immune system. Measuring MPO activity is vital for understanding neutrophil characteristics and functions in various diseases. MPO activity can be measured using several methods, including spectrophotometric and fluorometric protocols.

An optimized protocol for estimating cellulase activity in biological samples.

Cellulase is a microbial enzyme responsible for degrading the β-1,4 glycoside bond in polysaccharide cellulose, which is abundant in various animal foodstuffs. Cellulase is an important industrial enzyme used for various purposes, including biopolishing textile fibers, softening garments, biostoning denim fabric, and removing excess color from textiles. In the food industry, cellulase is combined with pectinase and hemicellulase.

A New Method to Estimate Inhibition Percentage of Endogenous Digitalis in Patients with Pre-eclampsia.

Background: Pre-eclampsia is an idiopathic pregnancy disorder characterized by appearance proteinuria and hypertension, with poorly understood etiology. It has been linked to a variety of system abnormalities, including ion transport disorders in neonatal, maternal, and placental cell lines. A new method was described to evaluate the inhibition percentage of endogenous digitalis in plasma of pre-eclampsia patients compared with normal pregnancies, with the estimation of sensitivity and specificity of the proposed test.
