Background: Alterations of trace elements, could induce metabolic disorders as they forthwith participating in the metabolic pathways and play different roles modulating it as well as many enzymes require trace elements for their activation and functions. Of these elements, selenium (Se), zinc (Zn), copper (Cu) and manganese (Mn) have been recognized as essentials for metabolism. hyperglycemia and diabetes mellitus are important causes of mortality and morbidity worldwide, and their global prevalence are growing from 2.8% in 2000 projecting to be 4.4% in 2030. Diabetes is prevalent in Saudi Arabia with high incidence in urbanized areas and its prevalence is estimated to expand 3 times by 2030. Patients and Methods: In total, 75 diabetic women and 80 aberrantly healthy women were recruited. Clinical and familial history was recorded. hair Se, Zn, Cu and Mn levels were analyzed as well as fasting blood sugar (FBS), glycated hemoglobin (hbA1c). Results: Our findings revealed a marked decrease of Zn and Mn levels in diabetic women hair compared to control group (p herwise, Se and Cu levels were significantly elevated in hair of diabetic patients (p he trace elements balance as well as their alterations can affect glucose metabolism and insulin action. Chronic hyperglycemia can cause disturbance of some trace elements which, in turn, can modulate glucose homeostasis. The metabolic dysregulation occurring in hyperglycemia may influence trace element status by increasing excretion, diminishing availability or redistribution of trace elements among different body pools. hair trace elements can be useful long-term markers for metabolic disturbance;however, larger prospective studies are required to validate their role in diagnosis and follow up applications.

Background: Epstein-Barr virus (EBV) is a double-stranded linear DNA human herpesvirus that is transmitted primarily through saliva during childhood. Although the majority of primary EBV infections are clinically asymptomatic, clinical cases are presented as infectious mononucleosis (IMN) syndrome. Objectives: This study was conducted to explore the rate of EBV anti-VCA IgG among children who were clinically suspected as having IMNin Diyala province. Subjects and Methods: This is a cross sectional study that was carried out during 2018 in Diyala province-Iraq. A total of 370 blood samples were collected from 190 children under 15 years of age who were clinically suspected as having IMN, and 180 apparently healthy children as controls. The anti EBV VCA IgG antibodies were detected in serum using the VCA IgG ELISA kit (from *** Diagnostic Bioprobessrl-Italy). Statistical analysis was carried out using the SPSS-version 25. A statistical significance was considered whenever the P value was ≤ 0.05. Results: The results showed that the IgG positivity rate among suspected IMN patients was insignificantly higher in the age group 10 - 14 years old children (80.8%, P = 0.364). In control subjects the highest positivity rate was in the age group of 1 - 4 years with a statistically significant difference (79.5%, P = 0.002). In suspected IMN patients, the age group of 10 - 14 years had the highest mean concentration ± SD of anti-VCA IgG 44.018 ± 38.644 arbitrary units per milliliter (arbU/ml), while in controls, the highest value 38.018 ± 34.908 (arbU/ml) was in the age group of 1 - 4 years, with insignificant difference in either group (P = 0.257 and 0.072, respectively). The results also showed that in both suspected IMN patients and control subjects, females showed higher IgG positivity rate (70.6%, and 75.5%) compared to males (64.8%, and 65.1%) with insignificant difference in both groups (P = 0.392 and 0.126) respectively. Similarly, the IgG mean concentration ± SD was

Nano-ZnO particle was produced by evaporating zinc powders in air at air flow-rate from 0.2 to 0.6m3/h. Nano-ZnO particles was formed by the oxidation of the evaporated zinc vapor. X-ray diffraction shows the powders to be ZnO with lattice parameters of a=0.3249nm and c=0.5205nm. The particle size is dependent upon the transit time from the source to the collection area. The size of particles was ranged between 81 to 103nm. The average density resulted was 4.865g/cm3. Normal ZnO and nano-ZnO were investigated to use them in aluminum metallurgy as an inert anode material. A certain amount of both oxides were molded subsequently inserted to the molten cryolite-aluminum oxide to investigate the corrosive behavior of both oxides. When the sintering temperature increased up to 1300℃, the weight loss ratio rose to 5.01%-7.33% and up to 7.67%-10.18% for nano-ZnO and normal ZnO, respectively. however, when the samples in the molten cryolite aluminum oxide were put for long time, the corrosive rate was found to be higher. It was found that the corrosive loss weight ratio of nano-ZnO anode was much lower than the normal one made from ordinary-ZnO providing that the nano-ZnO is more possible to be use inert anode material.

Indirect detection of Escherichia coli and total coliforms can be based on the enzymatic activities of β-glucuronidase (β-glu) and β-galactosidase (β-gal). These enzymes utilize the substrates anthracene-β-d-glucuronide and pyrene d-galactopyranoside, respectively. Substrate cleavage by the enzyme releases the soluble fluorescent molecules 2-hydroxyanthracene and 1-hydroxypyrene, which can then be detected by a fluorometer. The Pathogen Detect? system is an automated portable unit that can measure fluorescent enzyme products. In this report, we investigated the utility of the Pathogen Detect? system for potential automation of water quality monitoring. The PDS unit has the ability to detect E. coli, mean 14.7 h at a standard deviation of 1.5, when the sample mean is 9.1 cells in 100 mL with a standard deviation of 12.6. Similarly, total coliforms may be detected at mean 14.7 h with a standard deviation of 1.4 when the sample mean is 59.6 cells in 100 mL, with a standard deviation of 144.5. The PDS unit has the ability to detect single cells of either total coliforms or E. coli in 100 mL water sample within 18 hours. Turbidity and color of water samples have no impact on the detection of E. coli and total coliforms.
