1. Comparison of glucose measurement on dried blood spots versus plasma samples in pregnant women with and without anemia
ABSTRACT Objective Compare the concordance degree between plasma glucose and glucose measurements on Dried Blood Spots (DBS) during pregnancy. Subjects and methods Glucose measurement was performed in pregnant women after a fast of 8-12 hours. Venous blood was collected with sodium fluoride, the plasma was separated, and glucose measured by the enzymatic

3. Isoenzyme and molecular approach for authenticating and monitoring of animal cell lines
Abstract: Authentication of cell lines is of paramount importance to validate the results from their use in biomedical research. Although isoenzyme polymorphism is the standard method, molecular methods based on mitochondrial DNA (mtDNA) have been developed to replace it. The aim of this study was the improvement of our isoenzyme electrophoretic analysis and

5. A Novel Colorimetric Immunoassay of Ultrasensitive Alpha-Fetoprotein Sensing in Magnetic Bead-Based Mimic Enzyme-Chromogenic Substrate System
This work described a simple and feasible colorimetric immunoassay. Using hemin (a horseradish peroxidase (HRP) mimic enzyme) and the mimic enzyme-chromogenic substrate system, it can qualitatively and quantitatively detect a-fetoprotein (AFP) at an ultralow concentration. The glucose oxidase (GOx) catalyzed oxidation of glucose leads to the formation of glu

6. Effect of glucose oxidase addition on the textural characteristics of wheat-maize dough and bread
Abstract The aim of this study was to assess the effect of adding glucose oxidase (GOX) on wheat-maize dough and bread textural characteristics. It strengthens the importance and need of replacing wheat flour with maize flour in regions where extensive cultivation of wheat is not possible. For improving the rheological properties of bread, GOX was added to

12. Biochemical changes and color properties of fresh-cut green bean (Phaseolus vulgaris L. cv.gina) treated with calcium chloride during storage
Calcium chloride is widely used in industries as a firming agent, and also to extend shelf-life of vegetables. The aim of this study was to determine, the effect of different doses of calcium chloride on biochemical and color properties of fresh-cut green bean. Fresh-cut green beans were dipped for 90 seconds in 0.5%, 1%, 2% and 3% solution of calcium chlori
