Background: The altered status of some essential trace elements observed in diabetes could have deleterious influences on the health of the diabetics. Objectives: To estimate and study the potential role of serum Selenium in type 1, type 2 diabetics and healthy subjects; and its relation with lipid profile and glycemic index. Methods: A case control designed study was carried out at the National Diabetes Center (NDC) / Al-Mustansiria University; on a total of 94 participants formed of 32 type 1 diabetics, 32 type 2 diabetics and 30 healthy control participants. Data collected about age, sex and BMI; also, blood samples examined for FPG, HbA1C, serum total cholesterol, HDL cholesterol, non-HDL cholesterol, serum triglyceride and sera were examined for Selenium by using atomic absorption technique. Results: Type 1 and type 2 diabetic groups show respectively 75% and 65% decrement in S. Selenium, <70 µg/L. The mean of S. Selenium, age, BMI, waist/hip ratio, FPG, HbA1c, total cholesterol, triglyceride, HDL, Non-HDL and atherogenic index (total cholesterol/HDL cholesterol) for the type 1 and type 2 diabetics shows statistically significant differences from control group. Type 1 diabetics versus type 2 diabetics shows statistically insignificant differences between mean of the S.Selenium, total cholesterol, HDL cholesterol and atherogenic index (t-test, P > 0.05) while the mean of FPG, HbA1c and triglyceride show highly statistical significant differences (t-test, < 0.001).Simple linear correlation and regression analysis of FPG, HbA1c, total cholesterol, triglyceride, HDL, Non-HDL and atherogenic index of the studied groups shows weak to moderate correlation with their serum Selenium levels. Conclusions: The inverse relationship between Selenium status and glucose tolerance suggest the potential role of Selenium in diabetics. Serum Selenium levels show high statistically significant differences from healthy subjects; while the differences between type1 and type 2 diabetic groups’ shows no statistically significant differences. Inverse correlations and regression were noticed between S.Selenium levels of all studied groups with their FPG, HbA1c, total cholesterol, triglyceride, HDL, Non-HDL and atherogenic index. Low S.Selenium and HDL-cholesterol plus an increase in total cholesterol, non-HDL and atherogenic index enhance risk of cardiovascular diseases progression among the diabetics.
Background: The world is in front of two emerging problems being scarceness of virgin re-sources for bioactive materials and the gathering of waste production. Employment of the surplus waste in the mainstream production can resolve these problems. The current study aimed to prepare and characterize a natural composite CaO-SiO2 based bioactive material derived from naturally sustained raw materials. Then deposit this innovative novel bioactive coating composite materials overlying Yttria-stabilized tetragonal zirconia substrate. Mate-rials and method; Hen eggshell-derived calcium carbonate and rice husk-derived silica were extracted from natural resources to prepare the composite coating material. The manufac-tured powder was characterized

Green synthesis is depending on preparation of nano composited SiO2/V2O5 by using the modified sol-gel method depending on rice husk ash as a source for the extraction of silica gel and the product powder of nano composited SiO2/V2O5 characterization by many techniques such as X-ray diffraction spectroscopy (XRD), field emission scanning electron microscopy (FESEM), and N2 adsorptions/desorption isotherms (BET). This study also includs the biological effectiveness of SiO2/V2O5 and its effect on inhibiting bacterial growth after the prepared nanomaterial was applied to wound dressings, which gave a promising result for its use as

Promoting the production of industrially important aromatic chloroamines over transition-metal nitrides catalysts has emerged as a prominent theme in catalysis. This contribution provides an insight into the reduction mechanism of p-chloronitrobenzene (p-CNB) to p-chloroaniline (p-CAN) over the γ-Mo2N(111) surface by means of density functional theory calculations. The adsorption energies of various molecularly adsorbed modes of p-CNB were computed. Our findings display that, p-CNB prefers to be adsorbed over two distinct adsorption sites, namely, Mo-hollow face-centered cubic (fcc) and N-hollow hexagonal close-packed (hcp) sites with adsorption energies of −32.1 and −38.5 kcal/mol, respectively. We establish that the activation of nit

This study presents the debonding propagation in single NiTi wire shape memory alloy into linear low-density polyethylene matrix composite the study of using the pull-out test. The aim of this study is to investigate the pull-out tests to check the interfacial strength of the polymer composite in two cases, with activation NiTinol wire and without activation. In this study, shape memory alloy NiTinol wire 2 mm diameter and linear fully annealed straight shape were used. The study involved experimental and finite element analysis and eventually comparison between them. This pull-out test is considered a substantial test because its results have a relation with behavior of smart composite materials. The pull-out test was carried out by a u
