Abstract The present article gives an overview of recent publications and modern techniques sample preparation for food analysis employing atomic inorganic mass spectrometric techniques, such as flame absorption spectrometry, chemical vapor generation fluorescence graphite furnace inductively coupled plasma optical emission spectrometry. Among the most frequently applied are dry ashing, usually with addition ashing aid, acid digestion, preferably assistance microwave energy. Slurry...
The aim of this work was to evaluate the microemulsification as sample preparation procedure for determination Cu, Fe, Ni and Zn in vegetable oils samples by High-Resolution Continuum Source Flame Atomic Absorption Spectrometry (HR-CS FAAS). Microemulsions were prepared mixing with propan-1-ol aqueous acid solution, which allowed use inorganic standards calibration. To a mass 0.5g, 100μL hydrochloric added resulting mixture diluted final volume 10mL. manually shaken visually homogeneous...
Glycosylation of recombinant human erythropoietin (rHuEPO) is a post-translational process that alters biological activity, solubility and lifetime the glycoprotein in blood, strongly depends on type cell culture conditions. A fast simple method providing extensive carbohydrate information about glycans present rHuEPO other glycoproteins needed order to improve current methods drug development or product quality control. Here, an improved for intact glycoform characterization by CZE-ESI-TOF...
<h3>Objective.</h3> —To determine whether optimized glycemic control in type I diabetic recipients of renal allografts will prevent or delay lesions the allograft. <h3>Design.</h3> —Prospective, controlled, and randomized trial an inception cohort allograft recipients. The experimental group underwent maximized control, standard was treated same way as other patients transplant clinic. Patients baseline (before transplant) 5-year posttransplant biopsies. <h3>Setting.</h3> —University...
Standard pH values; pH(s), for five reference buffer solutions, KH tartrate, KH2 citrate, phthalate, acetate and phosphate in acetonitrile–water mixtures containing 10, 30, 40, 50, 70 100 wt. % acetonitrile at 298.15 K have been determined using the IUPAC standardization rules. The relationship between pH(s) solvent composition, expressed as a fraction, studied, with view to assessing presence of preferential solvation effects. In order obtain values all possible mixtures, linear energy...
We examined the rate of development lesions diabetic nephropathy in transplanted kidneys residing for 6–14 yr type I (insulin-dependent) kidney-allograft recipients. Although each recipient had end-stage with his/her own kidneys, there was marked variability mesangial expansion observed kidneys. The progression glomerular pathology, including widening basement membrane and mesangium, did not correlate significantly several potential risk factors (e.g., donor source—cadaver or living related,...
