Biochemical and Histological Study of Aminoacylase-1 Purified from Amniotic Fluid in Rats with Oxidative Stress Induced by Lead Acetate
...Show More Authors

This work involves separating and studying the aminoacylase-1 (ACY1) of amniotic fluid from healthy pregnant, mainly one peak with higher activity has been isolated by DEAE-Cellulose ion exchange from the proteinous supernatant produced by deposition of proteins using ammonium sulfate  (65%) after dialysis. The purification folds reaching to 19 folds also gave one protein peak when injected into the gel filtration column, a high ACY1 purity was obtained, with 38 folds of purification. It was found that the molecular weight of the isolated ACY1 was up to 46698 Dalton when using gel chromatography technique.The effect of ACY1 isolate was studied on rats with oxidative stress caused by lead acetate(LA) at 40 mg / kg body weight and compared with normal rats by measuring the selected biochemical parameters which included: Glutathione (GSH), malondialdehyde (MDA), aspartate aminotransferase (AST) and alanine aminotransferase (ALT) through liver and kidney tissue examination. The results showed a significant increase in the levels of (MDA, AST, ALT) and a decrease in the level of GSH compared with the control group, Also it has been observed there that was a significant decrease in the levels of (MDA, AST, ALT) and high level of GSH when injecting the ACY1 isolate in a dose of 4 mg / kg of rat weight with LA at 40 mg/kg. The results of the tissue examination demonstrated high pathological changes in the liver tissue of rats treated with LA at 40 mg/kg of rat weight when compared with normal rats. The liver and kidney tissue improved when treated with isolate at 4 mg / kg rat weight and LA. These results demonstrate the role of ACY1 in protecting from oxidative stress then can reduce the severity of various diseases.

Future Scenario of Global Climate Map change according to the Köppen -Geiger Climate Classification
...Show More Authors

Earth’s climate changes rapidly due to the increases in human demands and rapid economic growth. These changes will affect the entire biosphere, mostly in negative ways. Predicting future changes will put us in a better position to minimize their catastrophic effects and to understand how humans can cope with the new changes beforehand. In this research, previous global climate data set observations from 1961-1990 have been used to predict the future climate change scenario for 2010-2039. The data were processed with Idrisi Andes software and the final Köppen-Geiger map was created with ArcGIS software. Based on Köppen climate classification, it was found that areas of Equator, Arid Steppes, and Snow will decrease by 3.9 %, 2.96%, an

Fenton-like degradation of direct blue dye using green synthesised Fe/Cu bimetallic nanoparticles
...Show More Authors

This study relates to synthesis of bentonite-supported iron/copper nanoparticles through the biosynthesis method using eucalyptus plant leaf extract, which were then named E-Fe/Cu@B-NPs. The synthesised E-Fe/Cu@B-NPs were examined by a set of experiments involving a heterogeneous Fenton-like process that removed direct blue 15 (DB15) dye from wastewater. The resultant E-Fe/Cu@B-NPs were characterised by scanning electron microscopy, Brunauer–Emmet–Teller analysis, zeta potential analysis, Fourier transform infrared spectroscopy and atomic force microscopy. The operating parameters in batch experiments were optimised using Box–Behnken design. These parameters were pH, hydrogen peroxide (H2O2
