“…In our study, we found that liver enzymes such as AST, ALT, ALP, and GGT were significantly increased in the patients with ALD ( p < 0.001) when compared with the healthy control subjects. Similar findings were observed by Cuschieri and Baker, 10 Konttinen et al, 19 Matloff et al, 20 Moussavian et al, 21 Das and Vasudevan, 22 Maithreyi et al, 23 Mirunalini et al, 24 Jang et al, 25 Al-Jumaily, 26 Hyder et al, 27 Gayathri and Vasantha, 28 and Brandl et al 29 However, our findings are contradictory to the study conducted by Hourigan and Bowling 30 who found normal levels of serum AST and ALT in patients with alcoholic cirrhosis. Whereas, in the study conducted by Seth et al 31 there was no significant difference in serum ALT level between the cases and controls ( p = 0.21).…”

Background Alcoholic liver disease (ALD) is a major source of alcohol-related morbidity and mortality. Heavy drinkers and alcoholics may progress from fatty liver to alcoholic hepatitis to cirrhosis. The enzyme γ-glutamyltranspeptidase (GGT) is a membrane-bound glycoprotein which catalyzes the transfer of the γ-glutamyl group from γ-glutamyl peptides to other peptides, amino acids, and water. Serum GGT activity mainly attributed to hepatobiliary system and thus is an important marker of ALD. Hence the present study is conducted to estimate and correlate the levels of GGT and osteopontin (OPN) in ALD. Aims and Objectives The objective of this study is to estimate and correlate the levels of GGT and OPN in ALD. Materials and Methods Sixty clinically diagnosed cases of ALD and sixty age- and gender-matched healthy controls were recruited for the study. Blood samples were collected from them and serum aspartate aminotransferase, serum alanine transaminases (ALTs), serum ALP levels, and plasma OPN levels were measured. Estimation of serum aspartate transaminases (AST), ALTs, and alkaline phosphatase (ALP) was assayed by standard photometric methods in autoanalyzer ERBA-XL (EM-200) using commercially available kits. OPN was estimated by using commercial kit based on enzyme-linked immunosorbent assay. Results The parameters of the liver function tests such as AST, ALT, and ALP were significantly increased in patients with ALD (p < 0.001) when compared with the healthy control subjects. In the present study, significantly increased levels of γ-glutamyl transferases and OPN were found in patients with ALD (p < 0.001) when compared with the control subjects. OPN showed significant positive correlations with AST (r = 0.76, p < 0.001), ALT (r = 0.64, p < 0.001), ALP (r = 0.68, p < 0.001), and GGT (r = 0.61, p < 0.001). Conclusion The present study focuses on the role of GGT and OPN that are sensitive indicators of liver cell injury and are most helpful in recognizing hepatocellular diseases such as ALD, hepatitis, and liver cirrhosis. Hence, the pattern of the GGT and OPN levels elevation can be helpful diagnostically.

Hot weather is one of the main problems the residential building construction field faces, especially in the southern hemisphere. Therefore, there is an increasing need to produce materials capable of reducing the high temperature impact. These materials should be characterized by thermal insulation properties without, though, their mechanical properties and load resistance being affected. In this research, cuboid and hexagonal hollow concrete blocks were produced from lightweight foam concrete with different hole shapes and a hole ratio of 30%. An analytical study was conducted for 8 models using the ANSYS v16 program, while the compression behavior and thermal performance of the selected models were studied. Ordinary Portland Cement (OPC), water, sand, and foaming agents were deployed in the production of foamed concrete. In addition to the use of admixtures, materials, such as Superplasticizer (SP), Class F Fly Ash (FA), and Silica Fume (SF), were also utilized. Moreover, the effect of the hole’s shape and the method of bonding were studied. The compressive strength of the concrete blocks, bond shear strength, thermal conductivity, and thermal resistance were tested. It was found that the cuboid shape of the hole block H7 was the most acceptable compared to the other shapes, with a compressive strength of 3.75 MPa, thermal conductivity of 0.149 W/m.k, and a bond shear strength of 0.157 MPa. At the same time, it was found that using bonding adhesive material gave the best results, with the cuboid blocks being compared to using mortar and mechanical bonding.
