Green Synthesis of Silver Nanoparticles via Black and Green Tea and Study its Toxicity on few Vital Organs of Female Mice
...Show More Authors

This study included synthesizing silver nanoparticles (AgNPs) in a green method using AgNO3 solution with glucose exposed to microwave radiation. The prepared NPs were also characterized using ultraviolet and visible (UV-vis) spectroscopy and scanning electron microscopy (SEM). The UV/vis spectroscopy confirmed the production of AgNPs, while SEM analysis showed that the typical spherical AgNPs were 30 nm and 50 nm in size for the NPs prepared using black tea (B) and green tea (G) as reducing agent, respectively. The changes in some of the biochemical parameters related to the liver and kidneys have been analyzed to evaluate the probable toxic effects of AgNPs. 40 adult male mice were included in this study. To assess the probable health effects of the prepared AgNPs, an experiment has been designed that includes 40 adult mice, and it was randomly divided into three groups as follows: Group I (C): The control group consisting of 10 animals was injected intraperitoneally with PBS for 15 days. Second (G): included 10 animals who were injected with 0.1 mL of (2) mg/kg (G) intraperitoneally for 15 days. Group B included 10 animals injected with 0.1 mL of (2 mg/kg) (B) solution intraperitoneally for 15 days. Changes in some biochemical parameters related to the liver and kidneys were analyzed to assess potential toxic effects on the function of these vital organs. The serum levels of alanine aminotransferase (ALT)(IU/L), alkaline phosphatase (ALP) (IU/L), and cholesterol (mg/dL) as parameters of liver function were analyzed, and the serum levels of uric acid, creatinine, and urea (mg/dL) were analyzed as parameters of kidney function. The results revealed that no significant changes occurred in organ weight in groups treated with AgNPs compared with the control. However, the results showed a significant increase in ALT enzyme level in the third group compared with its level in the control group. Meanwhile, there were no significant differences in ALT level between the second group and the control. The level of the anaplastic lymphoma kinase (ALK) enzyme was significantly increased in both groups (2 and 3) in comparison with its level in the control group. No significant differences were found in cholesterol levels between the groups. Also, there were no significant differences found in uric acid levels between the groups. At the same time, creatinine level increased significantly in group 2 (where the NPs prepared using Black tea as a reducing agent) compared to its level in the control group. Urea level increased significantly in both groups (2 and 3) in comparison with its level in the control group. We conclude that the submission to AgNPs causes toxicity in the liver and kidneys.

The strategic importance of the Strait of Malacca and its impact on the US-China rivalry
...Show More Authors

The Strait of Malacca is one of the waterways of strategic, political, and economic importance. This strait has an increasing importance to its neighboring countries. The Strait of Malacca is very important for China, especially in the field of energy supply security, as the vast ma jority of energy supplies come to China through this strait. China seeks to ensure its security, especially in light of the cooperation of countries that look forward to this strait as well as the United States, and what the United States may cause to China, as many of them are at war with China over the China Sea, not to mention the countries that overlook it. The importance of the research emerges from the basic idea that the strategic importance of the Strait

In vivo study of the expression of some immune markers in BALB/c mice exposed to Aspergillus fumigatus mycotoxin
...Show More Authors

Gliotoxin (GT) is sulfur-containing mycotoxin within the 2,5-diketopiperazines class. First discovery from Gliocladium. Later discovered from different strains belonging to Aspergillus fumigatus mainly those have glicluster. This study outlines a study on the histological effects of gliotoxin (GT) on mouse brain and spleen tissues using light and electron microscopy, with a focus on its interaction with matrix metalloproteinases (MMPs). Histopathological changes through MMPs expressing variability estimated by using Immunohistochemistry (IHC). Mature mice were injected intraperitoneally with acute doses determined by data response analysis (EC50/IC50) as (125, 250, and 500 μg/ml) of GT and compared with a control group that received (metha

Anti-obesity effect of simvastatin and omega-3 and its combination on obese model male Wistar rats: Effect of simvastatin, omega-3 and their combination on UCP1
...Show More Authors

      Strategies to reduce obesity have become main priority for many health institution and health staff around the world, as the prevalence of obesity has risen and exacerbated in most of the world mainly because of the modern life style which tend to be more sedentary with an increase eating unhealthy fast western food. Many years ago, the lipid-lowering drug simvastatin; and omega-3 were considered as a traditional lipid-lowering drug that have been well-documented to possess anti-inflammatory, cardioprotective and triglyceride-lowering properties; and their co-administration may demonstrate a complementary effect in lowering patients' triglycerides and total cholesterol to treat atherosclero

A mathematical model constructed to study the combined effects of the concentration and the thermodiffusion on the nanoparticles of a Jeffrey fluid with a magnetic field effect the process of containing waves in a three-dimensional rectangular porous medium canal. Using the HPM to solve the nonlinear and coupled partial differential equations. Numerical results were obtained for temperature distribution, nanoparticles concentration, velocity, pressure rise, pressure gradient, friction force and stream function. Through the graphs, it was found that the velocity of fluid rises with the increase of a mean rate of volume flow and a magnetic parameter, while the velocity goes down with the increasing a Darcy number and lateral walls. Also, t

Thermoplasmonic of Single Au@SiO2 and SiO2@Au Core Shell Nanoparticles in Deionized Water and Poly-vinylpyrrolidoneMatrix
...Show More Authors

Metal nanoparticles can serve as an efficient nano-heat source with confinement photothermal effects. Thermo-plasmonic technology allows researchers to control the temperature at a nanoscale due to the possibility of precise light propagation. The response of opto-thermal generation of single gold-silica core-shell nanoparticle immersed in water and Poly-vinylpyrrolidone surrounding media is theoretically investigated. Two lasers (CW and fs pulses) at the plasmonic resonance (532 nm) are utilized. For this purpose, finite element method is used via COMSOL multiphysics to find a numerical computation of absorption cross section for the proposed core –shell NP in different media. Thermo-plasmonic response for both lasers is studied. The

The influence of excellent offensive basketball skill-learning activities based on sensory perceptions for female pupils.
...Show More Authors

The aim of this research is to develop qualitative workouts based on certain sensory perceptions for the development of offensive basketball abilities and to determine their impact on female pupils. Several findings, based on the au-thor's extensive expertise instructing basketball materials and our closeness to the sample, revealed deficits in some sensory perceptions “in the game of basketball”, which impair the accuracy of passing the ball to the best team-mate. It also affects the pace of dribbling and the difficulty of selecting the op-timal moment and distance to fire. Therefore, the researcher designs qualita-tive activities based on many sensory experiences, including distance, speed, force, and direction shift. In addition, the
