Diabetes mellitus is a metabolic disorder categorized hyperglycemia resulting from defects in insulin secretion, insulin action or both. Protein tyrosine kinase (PTK) is an enzyme that catalyzes the transfer of phosphate groups from ATP to the tyrosine residues of many important proteins resulting in proteins phosphorylation. The aim of current study was to evaluate serum levels of protein tyrosine kinase enzyme and thyroid hormone (T3, T4and TSH) and to find the correlation between them in type 2 diabetes mellitus and diabetic nephropathy Iraqi patients. Methods: This study was conducted at The National Diabetes Center, Al-Mustansiriya University, Baghdad, Iraq and included 150 patients divided into three groups the first group included 50 Iraqi patients newly diagnosis with type 2 diabetic, as group2, the other group included 50 patients with diabetic nephropathy as group3, and the last group included 50 healthy subjects as controls. as group1. The period of time for collection of blood samples extended from July to October 2017. All patients were between 18 and 60 years old. Results: The results of current study showed that the mean±SD levels of serum T3 in G3 was 1.77±0.19ng/mL and in G2 was 1.67±0.2ng/mL; whereas in G1 was 1.69±0.23ng/mL (P>0.05). On the other hand, the mean±SD levels of serum T4 were 8.99±0.58ng/mL, 8.84±0.69ng/mL and 8.55±0.81ng/mL in the G3, G2 and G1 groups, respectively, (P3 in G1 and G2 (r= 0.200, r= 0.068, respectively, (P>0.05) while non-significant negative correlation existed between tyrosine kinase and T3 in G3 (r =-0.154) (P>0.05). Non-significant negative correlation was observed between tyrosine kinase and T4 in G1(r=-0.014) (P>0.05). In addition, non-significant positive correlation was observed between tyrosine kinase and T4 in G2 and G3 (r = 0.178, r= 0.073, respectively) (P>0.05).

Mass transfer has been studied at rotating cylinder electrodes fabricated with spiral-wound woven-wire meshes using reduction of copper as a test reaction. The experimental data were correlated by an empirical expression between the Sherwood number and the Reynolds number, both regarding the hydraulic diameter as a characteristic length. It was found that the Sherwood number was dependent upon the Reynolds number to the power of 0.521. An enhancement factor was adopted to compare the efficiency of the new rotating cylinder electrode with previous three-dimensional rotating cylinder electrodes. The results showed that the new type has a mass-transfer enhancement factor 2.3 times higher than those obtained with smooth rotating cylinder electr

Rapid worldwide urbanization and drastic population growth have increased the demand for new road construction, which will cause a substantial amount of natural resources such as aggregates to be consumed. The use of recycled concrete aggregate could be one of the possible ways to offset the aggregate shortage problem and reduce environmental pollution. This paper reports an experimental study of unbound granular material using recycled concrete aggregate for pavement subbase construction. Five percentages of recycled concrete aggregate obtained from two different sources with an originally designed compressive strength of 20–30 MPa as well as 31–40 MPa at three particle size levels, i.e., coarse, fine, and extra fine, were test

Hypothesis CO2 geological storage (CGS) involves different mechanisms which can store millions of tonnes of CO2 per year in depleted hydrocarbon reservoirs and deep saline aquifers. But their storage capacity is influenced by the presence of different carboxylic compounds in the reservoir. These molecules strongly affect the water wetness of the rock, which has a dramatic impact on storage capacities and containment security. However, precise understanding of how these carboxylic acids influence the rock’s CO2-wettability is lacking. Experiments We thus systematically analysed these relationships as a function of pressure, temperature, storage depth and organic acid concentrations. A particular focus was on identifying organic acid conce
