| 1 | Effect of supplementing layer hen diet with phytogenic feed additives on laying performance, egg quality, egg lipid peroxidation and blood biochemical constituents显示文摘This study was conducted to evaluate the effects of supplementing laying hen diet with phytogenic additives on laying performance, egg quality, blood constituents and egg lipid peroxidation. Two hundred Lohmann Brown Lite laying hens were randomly allotted to 4 dietary treatments: control(without phytogenic additive), fennel seeds(5 g/kg), black cumin seeds(5 g/kg) and hot red pepper(5 g/kg).Each of the 4 diets was fed to 5 replicates of 10 hens for 8 weeks. No significant differences were observed in body weight or feed intake between the groups. Dietary inclusion of fennel followed by red pepper improved(P < 0.05) egg weight, egg production, egg mass and feed conversion ratio compared with control. Higher yolk shape index, shell and albumen weight percentages and Haugh unit(P < 0.05)were recorded in the fennel supplemented group compared with control. The egg yolk color score increased by the addition of fennel or hot red pepper in laying hen diets compared with control. The inclusion of black cumin or hot red pepper decreased serum and egg yolk cholesterol and malondialdehyde concentrations(P < 0.05) compared with control. Serum aspartate aminotransferase concentration was lower in black cumin group(P < 0.05) than in other treatments. In conclusion, the best laying performance and egg quality were obtained by dietary inclusion of fennel, followed by hot red pepper and black cumin. Dietary supplementation of black cumin or red pepper may lead to the development of low-cholesterol concentration and better antioxidant capacity of eggs. | Reham Abou-Elkhair Shaimaa Selim Eman Hussein | 2018 | Animal Nutrition2018，，4： | 6 |
| 2 | Cyanidin 3-glucoside modulated cell cycle progression in liver precancerous lesion,in vivo study显示文摘BACKGROUND Cyanidin-3-O-glucoside(cyan)exhibits antioxidant and anticancer properties.The cell cycle proteins and antimitotic drugs might be promising therapeutic targets in hepatocellular carcinoma.AIM To investigate the effect of cyan administration on cell cycle in hepatic precancerous lesion(PCL)induced by diethylnitrosamine/2-acetylaminofluorene(DEN/2-AAF)in Wistar rats.METHODS In vivo,DEN/2-AAF-induced hepatic PCL,rats were treated with three doses of cyan(10,15,and 20 mg/kg/d,for four consecutive days per week for 16 wk).Blood and liver tissue samples were collected for measurement of the followings;alpha fetoprotein(AFP)liver function and RNA panel differential expression was evaluated via real time polymerase chain reaction.Histopathological examination of liver sections stained with H&E and immunohistochemical study using glutathione S-transferase placental(GSTP)and proliferating cell nuclear antigen(PCNA)antibodies were assessed.RESULTS Cyan administration mitigated the effect of DEN/2-AFF induced PCL,decreased AFP levels,and improved liver function.Remarkably,treatment with cyan dose dependently decreased the long non-coding RNA MALAT1 and tubulin gamma 1 mRNA expressions and increased the levels of miR-125b,all of which are involved in cell cycle and mitotic spindle assembly.Of note,cyan decreased GSTP foci percent area and PCNA positively stained nuclei.CONCLUSION Our results indicated that cyan could be used as a potential therapeutic agent to inhibit liver carcinogenesis in rat model via modulation of cell cycle. | Marwa Matboli Amany H Hasanin Reham Hussein Sarah El-Nakeep Eman K Habib Rawan Ellackany Lobna A Saleh | 2021 | World Journal of Gastroenterology2021，27，14： | 1 |
| 3 | Optimization of double chamber microbial fuel cell for domestic wastewater treatment and electricity production显示文摘Microbial fuel cells(M FCs)represent a new approach for treating w aste w ater along w ith electricity production.The present study addressed electricity production from domestic w astew ater using a mediator-less double chamber M FC.The electricity production w as monitored under different operational conditions for both summer and w inter samples.Optimization of the anodic and cathodic chambers resulted in a maximal current of 0.784 and 0.645 m A w ith the maximal pow er intensity of 209 and 117 m W/m2in pow er duration of 24 h for the summer and w inter samples,respectively.Scanning electron microscopy show ed that the bacterial biofilm formation on the anode w as denser for the summer sample than that w hen the w inter sample w as used,so w as the total bacterial count.Therefore,samples taken during summer w ere considered better in electricity production and w aste w ater treatment than those taken during w inter basically because of the high microbial load during the hot season.In parallel,there w as a decrease in both biological oxygen demand(BOD5)and chemical oxygen demand(COD)values which reached 71.8%and 72.85%,respectively at the end of the operation process for the summer sample,w hile there w as no evident decrease for the w inter sample.Optimizing the operating conditions not only increased the potential of using domestic w aste w ater in microbial fuel cells to produce electricity,but also improved the quality of the domestic w aste w ater. | Amr El-Hag Ali Ola M.Gomaa Reham Fathey Hussein Abd El Kareem Mohamed Abou Zaid | 2015 | 燃料化学学报2015，43，9： | 1 |
