The effect of hemolysis on several assays performed with the Hitachi 717 was quantified by relating the amount of error to the concentration of hemoglobin. Hemolysis interference was judged clinically significant when analyte concentration varied by > 10% from the initial value. Hemolysis interference was significant for alkaline phosphatase, aspartate aminotransferase, alpha-amylase, bilirubin...

We describe an approach for the simultaneous determination of isoenzymes of alkaline phosphatase (EC 3.1.3.1) based on the kinetic behavior of inhibition reactions. Data for absorbance vs time, collected while enzymes are being inhibited, are fitted with suitable models to obtain results related to activities of the individual isoenzymes. The primary focus is on two-component mixtures of the bo...

background: to investigate the effect of cana2-edta and experimental diabetes (iddm) on zinc and carbohydrate metabolism and the activities of got, gpt and alkaline phosphatase. methods: forty male normal albino (wistar) rats of 8 weeks of age were fed with a basal diet. twenty rats were then intraperitoneally injected with alloxan to induce diabetes. then after one week ten rats from each grou...

Accurate information on the chemical nature of soil phosphorus is essential for understanding its bioavailability and fate in wetland ecosystems. Solution phosphorus-31 nuclear magnetic resonance (31P NMR) spectroscopy was used to assess the conventional colorimetric procedure for phosphorus speciation in alkaline extracts of organic soils from the Florida Everglades. Molybdate colorimetry mark...

introduction: salivary calcium and phosphate levels might have a relationship with dental caries severity. evaluation of different indexes such as alkaline phosphatase, which increases salivary phosphate levels, and hydroxyapatite ion activity, which reflects salivary calcium and phosphate levels, might help determine the risk of dental caries. the aim of the present study was to compare saliva...

conclusions the elevation of hmw-alp activity in cu treated animal suggests the occurrence of biliary disease. this may be used as a biomarker for the diagnosis of copper toxicity. results obtained data showed that with increasing administration of copper, the alp activity was elevated significantly. in comparison with the control group the elevations were between 20%-56% using gel filtration c...

human brucellosis is a major health problem in developing countries. a number of patients with human brucellosis do not recover from the acute stage of the disease and pass into the chronic form. since the pathophysiology of this change is not well understood, we studied the t-cell subsets during the acute, subacute and chronic forms of human brucellosis. in this study we found alterations in t...

Genetic Optimization for Alkaline pH of a Cyanide Dihydratase from Pseudomonas stutzeri. (April 2011) Alvaro Eugenio Rodriguez Mendoza Department of Biology Texas A&M University Research Advisor: Dr. Michael J. Benedik Department of Biology Even though cyanide is highly toxic, it is commonly found in industrial waste generated by several industries such as metal plating and mining. This chemica...
