Published: October 2019

Radon and its progenies are the main cause of lung cancer when they are trapped inside the lungs. Therefore, the radon activity concentration in air, water and soil samples should be measured, monitored and analysed. In this paper, river sediment samples collected from 30 different locations of Mahajran River, Basra, Iraq, were studied by using solid-state nuclear track detector type CR39. The track detector used for this purpose must be calibrated for concentrations of radon, Thoron and their daughters likely to be found in samples. The chamber used in the present calibration work had a volume of 125 L and contained a standard radon source (226Ra) and radon distribution fan. Results illustrated the dependence of the CR-39 calibration factor on the dosimeter height. The calibration factor used in this application was 0.34±0.0 Tr/cm2·day / Bq·m−3 for a height of 10 cm.

The study of oxidant-antioxidant status in type 2 diabetes mellitus
Authors: Farhood H B , Aljabery R N , Majid A
Published: October 2019

Hyperglycemia is considered a major initiator of oxidative stress which leads to the formation of free radicals and consequently lipid peroxidation occurs, which leads to tissue damage and diabetes mellitus development. Free radicals have been defined as intermediates of some biological redox reactions necessary for the maintenance of life. In presence of a free radical initiator and oxygen they may be oxidized this leading to lipid peroxidation, as it was suggested, might be associated with running out of hydrogen. In particular lipid peroxidation measured as levels of malondialdehyde (MDA). Glutathione (GSH), an intracellular thiol causes the eradication of free radicals or reduction in hydrogen peroxide level on state of oxidative stress. Decrease in the reduced GSH level has been reported in the erythrocyte of diabetics. Decrease in the level of GSH occurs both due to the competition between aldose reductase and glutathione reductase for NADPH, a cofactor, and increased oxidative stress (increased ratio of NADH/NAD). This study was conducted on 60 subjects. Informed consent was obtained from each person who agreed to participate in this study, while the survey was based on standardized interviews and questionnaire. Subjects were grouped as type 2-diabetics and healthy control with fasting plasma glucose (FPG) < 5.50 mmol/L. The ages ranged from 18 to 50 years. Glucose was determined by an enzymatic colorimetric test on basis of Trinder-Reaction. MDA was performed as described by Lipid Peroxidation Assay Kit (Colorimetric/Fluorometric), while the levels of GSH in all subjects were measured by the DetectX® Glutathione kit. The results show a significant elevation (P ≤ 0.05) in levels of glucose and MDA of type 2- diabetic patients in comparison with healthy subjects, which reached to 16.30 ± 0.50 mmol/L and 0.87 ± 0.19 nmol/mL for the type 2-diabetic patients, and 4.60 ± 0.15mmol L and 0.29 ± 0.5 nmol/mL for the control group, respectively. Also, it has been found a significant decrease (P ≤ 0.05) in GSH levels in type 2- diabetic patients, which reached to 3.43 ± 0.91 µM/mL in comparison with the control group which reached to 6.13±0.21 µM/mL. In conclusion we can observe that the increase in glucose levels leads to free radical formation by auto-oxidation and increase in lipid peroxidation (MDA levels), and inadequate antioxidant defense can occur during DM. In addition, GSH deficiency will make the present state worse by increasing the oxidative stress, since GSH is an important antioxidant.

PolyHIPEs for Water Treatment
Authors: Kadhim M , Oila A , Bull S J
Published: October 2019

PolyHIPEs (polymers synthesized within high internal phase emulsions) are porous materials with high specific surface area which suggests their use in ion exchange applications. We have successfully synthesized and functionalized such materials to make then hydrophilic by mixing an oil phase and an aqueous phase containing deionized water and sulphuric acid. The PolyHIPE samples were also subjected to a further microwave-assisted post-sulphonation process to increase hydrophilicity and water uptake. Post sulphonation results in a higher concentration of benzenesulphonic acid groups which are necessary for ion exchange. PolyHIPE beads processed in this manner were able to remove low concentrations (∼20mg/l) of nickel and copper ions from solution with high removal efficiency (80-95%) depending on the initial pH of the water. However, recovery of the metal through regeneration at different pH levels was less successful.

The interindividual varieties in the limit of changing development factor-β1 (TGF-β1) generation have been credited to hereditary polymorphisms in TGF-β1 quality. Changing development factor-beta 1 (TGFβ1) is a powerful suppressive cytokine that adds to ceaseless hepatitis B (CHB) disease. Abberations in TGFβ1 generation among people have been ascribed to TGFβ1 hereditary polymorphisms. We analyzed whether three putative polymorphisms in TGFβ1 (- 509 C/T (rs1800469), +869 C/T (rs1800470), and +11929 C/T (rs1800472)) square measure connected with CHB illness during a South-Eastern Iranian people.Methods:A total of 203 subjects with hepatitis infection (94 patients with hepatitis B virus infection and 109 patients with hepatitis C virus infection) whom admitted to Margan hospital, Center of liver diseases and gastrointestinal system were enrolled in the study. Allele specific (AS)-PCR, methods were used for assessing polymorphism of IL-10. Patients included (130 males and 73 females), with an age range (HBV: 44.6 ± 8.2), (HCV: 45.3±13.3) and (Control: 49.2 ± 9.04) years. The practical side of this study was done during the period from October 2017 to March 2018.Methods:A total of 203 subjects with hepatitis infection (94 patients with hepatitis B virus infection and 109 patients with hepatitis C virus infection) whom admitted to Margan hospital, Center of liver diseases and gastrointestinal system were enrolled in the study.

The heavy metals mainly include Pb, Hg, Cd, Cr, Cu, Zn, Mn, Ni, Ag, etc. The heavy metals,Pb,Cu,Zn are considered most toxic to humans, fishes and environment. highly concentrations of heavy metals are harmful They destabilize ecosystems because of their bioaccumulation in organisms, and toxic effects on biota and even death in most living beings. All heavy metals, in spite some of them are essential micronutrients, have their toxic effects on living organisms via metabolic interference and mutagenesis. The bioaccumulation of toxic metals can happen in the body and food chain. So, the toxic metals generally exhibit chronic toxicity. The heavy metals like Pb has significant toxic effects-The heavy metals are important pollutants for fishes, because these are not eliminated from aquatic systems by natural methods, such as organic pollutants, and are enriched in mineral organic substances. happen of heavy metals differs in fishes, depending on their age, development and other physiological factors. the fishes are apopulation which can be highly affected by these toxic pollutants. Heavy metals can have toxic effects on different organ-They can enter into the water by drainage, atmosphere, soil erosion, and all human activities in different ways. As the heavy metals concentrated more in the environment, they enter biogeochemical cycle, leading to toxicity.
