A New Method to Evaluate Fasting Plasma Glucose by Salivary Glucose Measurement

Objective:Fasting plasma glucose (FPG) analysis is the most importantmethod for detection and diagnosis of diabetes mellitus. Due to difficulty and problems of this method for determination of glycemia in diabetic patients, recently the use of Fasting Salivary Glucoseas a simple and non-invasive method to evaluate FPGhas came into significant considerationof specialists. The aim of this study w...

Measurement of Natural Radioactivity in Certain Types of Nut Samples in Iraq

Introduction: The present study was conducted to measure the specific activities of 226Ra,232Th and 40K, in some samples of nuts collected from the local markets in Iraq. In addition, this study sought to calculate the annual effective dose of gamma ray to children and adults. Material and Methods: The quantification of radionuclides was accomplished by gamma spectrometry NaI (Tl) detector. Res...

Plasma glucose measurement with the Yellow Springs Glucose Analyzer.

The Yellow Springs Glucose Analyzer, a device for the quantitative measurement of glucose concentrations, involves the use of immobilized glucose oxidase, incorporated on a membrane covering a hydrogen peroxide sensor. Operation of the instrument is simple. After an initial calibration, 25 microliter of plasma is injected into a reaction chamber. At 45 s a digital result for glucose is displaye...

Measurement of apolipoprotein B radioactivity in whole blood plasma by precipitation with isopropanol.

A method to measure apolipoprotein B radioactivity in whole blood plasma is described that is suitable for routine use in kinetic experiments in vivo. Radiolabeled apolipoprotein B is precipitated from plasma diluted 15- to 30-fold in the presence of carrier low density lipoproteins by 50% isopropanol. The amount of radioiodine in apoB is estimated from the difference between total radioiodine ...
