“…6.6.2023) was obtained from the herbarium of the Faculty of Science, Cairo University. The extract of Zingiber officinale roots was prepared using the maceration method (Handa et al., 2008 ; Villegas, 2016 ). A pressured hot water extraction method was used to extract the ginger powder (modified from Park et al., 2020 ).…”

Obesity became a serious public health problem with enormous socioeconomic implications among the Egyptian population. The present investigation aimed to explore the efficacy of Zingiber officinale extract as a hypolipidemic agent combined with the commercially well‐known anti‐obesity drug simvastatin in obese rats. Thirty‐five male Wister rats were randomly divided into five groups as follows: group I received a standard balanced diet for ten weeks; high‐fat diet was orally administered to rats in groups II–V for ten weeks. From the fifth week to the tenth week, group III orally received simvastatin (40 mg/kg B.W.), group IV orally received Z. officinale root extract (400 mg/kg B.W.), and group V orally received simvastatin (20 mg/kg B.W.) plus Z. officinale extract (200 mg/kg B.W.) separately. Liver and kidney function tests, lipid profiles, serum glucose, insulin, and leptin were determined. Quantitative RT‐PCR analysis of PPAR‐γ, iNOS, HMG‐CoA reductase, and GLUT‐4 genes was carried out. Caspase 3 was estimated in liver and kidney tissues immunohistochemically. Liver and kidney tissues were examined histologically. The administration of Z. officinale extract plus simvastatin to high‐fat diet‐fed rats caused a significant reduction in the expression of HMG‐coA reductase and iNOS by 41.81% and 88.05%, respectively, compared to highfat diet (HFD)‐fed rats that received simvastatin only. Otherwise, a significant increase was noticed in the expression of PPAR‐γ and GLUT‐4 by 33.3% and 138.81%, respectively, compared to those that received simvastatin only. Immunohistochemistry emphasized that a combination of Z. officinale extract plus simvastatin significantly suppressed caspase 3 in the hepatic tissue of high‐fat diet‐fed rats. Moreover, the best results of lipid profile indices and hormonal indicators were obtained when rats received Z. officinale extract plus simvastatin. Z. officinale extract enhanced the efficiency of simvastatin as a hypolipidemic drug in obese rats due to the high contents of flavonoid and phenolic ingredients.

“…Recently, there is a study of pollutants removal in diesel engines by using activated carbon [21]. In that study, some of activated carbons studied had surface area about 450-500 m 2 /g and can efficiently remove about 45-48% of pollutants in exhaust gases from diesel engines.…”

Preparation of Activated Carbon from Banana Peel Waste as Adsorbent for Motor Vehicle Exhaust Emissions

Air pollution caused by motor vehicle exhaust emissions in the form of harmful gases becomes a problem for the health of living things in the surrounding environment. The alternative way to reduce those emissions is by utilizing agricultural waste as activated carbon (AC). AC can adsorbs those emissions due to its porous and high surface area. AC was made of banana peel waste that contains of lignocellulose and has considerable amount because of banana processing industrialization. AC was made through dehydration, carbonization at 350°C furnace without or with N2 gases of 0.15 NL/minute for 1 hour, then chemical activation using various concentrations of H2SO4 solution at 85°C for 1 hour. Characterization of activated carbon was done by iodine number test. The result shows that carbon chemical activation by 6 N of H2SO4 gave better result of iodine number than the lower concentration, obtaining 428 mg/g and overall yield of 41.68%. The result was even better on physical-and-chemical activation with same concentration of H2SO4, obtaining 617 mg/g with surface area of 614 m2/g and overall yield of 56.40%.
