| 1 | 枯草芽孢杆菌及饲料粗蛋白质水平对肉鸡生长性能和肉鸡肠道形态的影响显示文摘试验通过检测肉鸡生长性能、胴体品质、肉品质和消化道发育情况、回肠CP消化率,探究日粮中添加枯草芽孢杆菌对肉鸡粗蛋白质(CP)需求量的影响。试验选取720只1日龄肉鸡。设置2×2方阵设计,包括按照标准CP水平设置的对照组(CP 100),在标准基础上降低2%CP含量的试验组(CP 98);不添加枯草芽孢杆菌组及添加枯草芽孢杆菌0.2 g·kg^(-1)组(0.8×10~9cfu·g^(-1),将肉鸡随机分配到各组。每组6个重复,每个重复30只肉鸡。育雏料、生长期饲料和育肥期饲料均按照标准制定,饲料中添加枯草芽孢杆菌对生长性能无显著影响。然而,随着日粮中CP水平下降,体增重和饲料效率显著下降(P<0.05),饲料中添加枯草芽孢杆菌可显著提高肉鸡胴体品质(P<0.05)。添加枯草芽孢杆菌对肉品质无显著影响,然而,随着日粮中CP含量下降,肉的保水力显著下降(P<0.05);空肠隐窝显著变深(P<0.05),回肠CP消化率显著提高(P<0.05)。试验结果表明,日粮中添加枯草芽孢杆菌可改善空肠形态,减缓日粮中CP含量减少的不利影响。因此,益生菌的使用可改变胃肠道形态特征,提高CP的回肠消化率,提高饲料效率。 | Mahmoud K Z Obeidat B S Al-Sadi M Z Hatahet Sh R | 2017 | 饲料博览2017，0，1： | 5 |
| 2 | Investigation of soliton solutions with different wave structures to the(2+1)-dimensional Heisenberg ferromagnetic spin chain equation显示文摘The principal objective of this article is to construct new and further exact soliton solutions of the(2+1)-dimensional Heisenberg ferromagnetic spin chain equation which investigates the nonlinear dynamics of magnets and explains their ordering in ferromagnetic materials.These solutions are exerted via the new extended FAN sub-equation method.We successfully obtain dark,bright,combined bright-dark,combined dark-singular,periodic,periodic singular,and elliptic wave solutions to this equation which are interesting classes of nonlinear excitation presenting spin dynamics in classical and semi-classical continuum Heisenberg systems.3D figures are illustrated under an appropriate selection of parameters.The applied technique is suitable to be used in gaining the exact solutions of most nonlinear partial/fractional differential equations which appear in complex phenomena. | M S Osman K U Tariq Ahmet Bekir A Elmoasry Nasser S Elazab M Younis Mahmoud Abdel-Aty | 2020 | Communications in Theoretical Physics2020，72，3： | 4 |
| 3 | Occult hepatitis B virus infection among Egyptian blood donors显示文摘AIM:To identify blood donors with occult hepatitis B virus(HBV) infection(OBI) to promote safe blood donation.METHODS:Descriptive cross sectional study was conducted on 3167 blood donors negative for hepatitis B surface antigen(HBsAg),hepatitis C antibody(HCV Ab) and human immunodeficiency virus Ab.They were subjected to the detection of alanine aminotransferase(ALT) and aspartate transaminase(AST) and screening for anti-HBV core antibodies(total) by two different techniques;[Monoliza antibodies to hepatitis B core(Anti-HBc) Plus-Bio-Rad] and(ARC-HBc total-ABBOT).Positive samples were subjected to quantitative detection of antibodies to hepatitis B surface(anti-HBs)(ETI-AB-AUK-3,Dia Sorin-Italy).Serum anti-HBs titers > 10 IU/L was considered positive.Quantitative HBV DNA by real time polymerase chain reaction(PCR)(QIAGEN-Germany) with 3.8 IU/mL detection limit was estimated for blood units with negative serum anti-HBs and also for 32 whose anti-HBs serum titers were > 1000 IU/L.Also,265 recipients were included,34 of whom were followed up for 3-6 mo.Recipients were investigated for ALT and AST,HBV serological markers:HBsAg(ETI-MAK-4,Dia Sorin-Italy),anti-HBc,quantitative detection of anti-HBs and HBV-DNA.RESULTS:525/3167(16.6%) of blood units were positive for total anti-HBc,64% of those were antiHBs positive.Confirmation by ARCHITECT anti-HBc assay were carried out for 498/525 anti-HBc positive samples,where 451(90.6%) confirmed positive.Reactivity for anti-HBc was considered confirmed only if two positive results were obtained for each sample,giving an overall prevalence of 451/3167(14.2%) for total anti-HBc.HBV DNA was quantified by real time PCR in 52/303(17.2%) of anti-HBc positive blood donors(viral load range:5 to 3.5 x 105 IU/mL) with a median of 200 IU/mL(mean:1.8 x 104 ± 5.1 x 104 IU/mL).AntiHBc was the only marker in 68.6% of donors.Univariate and multivariate logistic analysis for identifying risk factors associated with anti-HBc and HBV-DNA positivity among blood donors showed that age above thirty and marriage were the most significant risk factors for prediction of anti-HBc positivity with AOR 1.8(1.4-2.4) and 1.4(1.0-1.9) respectively.Other risk factors as gender,history of blood transfusion,diabetes mellitus,frequent injections,tattooing,previous surgery,hospitalization,Bilharziasis or positive family history of HBV or HCV infections were not found to be associated with positive anti-HBc antibodies.Among anti-HBc positive blood donors,age below thirty was the most significant risk factor for prediction of HBV-DNA positivity with AOR 3.8(1.8-7.9).According to HBV-DNA concentration,positive samples were divided in two groups;group one with HBV-DNA ≥ 200 IU/mL(n = 27) and group two with HBV-DNA < 200 IU/mL(n = 26).No significant difference was detected between both groups as regards mean age,gender,liver enzymes or HBV markers.Serological profiles of all followed up blood recipients showed that,all were negative for the studied HBV markers.Also,HBV DNA was not detected among studied recipients,none developed post-transfusion hepatitis(PTH) and the clinical outcome was good.CONCLUSION:OBI is prevalent among blood donors.Nucleic acid amplification/HBV anti core screening should be considered for high risk recipients to eliminate risk of unsafe blood donation. | Zeinab N Said Manal H El Sayed Iman I Salama Enas K Aboel-Magd Magda H Mahmoud Maged El Setouhy Faten Mouftah Manal B Azzab Heidi Goubran Amal Bassili Gamal E Esmat | 2013 | World Journal of Hepatology2013，5，2： | 4 |

| 5 | COVID-19 and hepatic injury: cellular and molecular mechanisms in diverse liver cells显示文摘The coronavirus disease 2019(COVID-19)represents a global health and economic challenge.Hepatic injuries have been approved to be associated with severe acute respiratory syndrome coronavirus(SARS-CoV-2)infection.The viral tropism pattern of SARS-CoV-2 can induce hepatic injuries either by itself or by worsening the conditions of patients with hepatic diseases.Besides,other factors have been reported to play a crucial role in the pathological forms of hepatic injuries induced by SARS-CoV-2,including cytokine storm,hypoxia,endothelial cells,and even some treatments for COVID-19.On the other hand,several groups of people could be at risk of hepatic COVID-19 complications,such as pregnant women and neonates.The present review outlines and discusses the interplay between SARS-CoV-2 infection and hepatic injury,hepatic illness comorbidity,and risk factors.Besides,it is focused on the vaccination process and the role of developed vac-cines in preventing hepatic injuries due to SARS-CoV-2 infection. | Fares E M Ali Mostafa K Abd El-Aziz Mahmoud M Ali Osama M Ghogar Adel G Bakr | 2023 | World Journal of Gastroenterology2023，29，3： | 2 |
