| 1 | Biochemical changes in phenols,flavonoids,tannins,vitamin E,β-carotene and antioxidant activity during soaking of three white sorghum varieties显示文摘Objective:To investigate the changes in total phenols,flavonoids,tannins,vitamin E, β-carotene and antioxidant activity during soaking of three white sorghum varieties.Methods: The changes in total phenols,total ilavonoids,tannins,phenolic acids compounds,flavonoid components,vitamin E,P-carotene and antioxidant activity during soaking of sorghum grains were determined.Results:Total phenols,total flavonoids,tannins,vitamin E,P-carotene and antioxidant activity in raw sorghum were ranged from 109.21 to 116.70,45.91 to 54.69,1.39 to 21.79 mg/100 g,1.74 to 5.25,0.54 to 1.19 mg/kg and 21.72%to 27.69%and 25.29%to 31.97%,respectively. The above measured compounds were significantly decreased after soaking.p-Hydroxybenzoic acid,vanillic acid,syringic acid and cinnamic acid represent the major phenolic acids in Dorado variety.While ferulic acid,p-coumaric acid,gallic acid and caffeic acid represent the major phenolic acids in Shandaweel-6.On the other hand,protocatechuic acid represents the major phenolic acids in Giza-15.Regarding flavonoids components,Dorado was the highest variety in kampferol and naringenin while Shandaweel-6 was the highest variety in luteolin, apigenin,hypersoid,quercelin and christen.Finally,Giza-15 was the highest variety in catechin. Phenolic acids,flavonoid compounds and antioxidant activities were decreased after soaking. Conclusions:Sorghum varieties have moderate quantities from total phenols,total flavonoids, tannins,phenolic acids compounds,flavonoid components,vitamin E,P-carotene and antioxidant activity which decreased after soaking. | Abd El-Moneim MR Afify Hossam S El-Beltagi Samiha M Abd El-Salam Azza A Omran | 2012 | Asian Pacific Journal of Tropical Biomedicine2012，2，3： | 7 |
| 2 | Acaricidal activity of different extracts from Syzygium cumini L.Skeels(Pomposia) against Tetranychus urticae Koch显示文摘Objective:To investigate the acaricidal activity of different extracts from Syzygium cumini(S.cumini)(Pomposia)againsst Tetranyckus urticae Koch(71 urticae)and the biochemical changes in antioxidants enzymes.Methods:Six extracts of S.cumini(Pomposia)at concentrations of 75,150 and 300μg/mL were used to control T.urticae(Koch).Results:The ethanol extract showed the most efficient acaricidal activity agent against T.urticae(98.5%)followed by hexane extract(94.0%),ether and ethyl acetate extract(90.0%).The LC_(50)values of the promising extract-were 85.0,101.0,102.0 and 98.0μ/mL,respectively.The activities of enzymes including ascorbate peroxidase(APX),peroxidase(POD),superoxide dismutase(SOD)and catalase(CAT)in susceptible mites were increased.The activities of all antioxidant enzymes reach the maximum value in mites at LC_(50)with ethanol and ethyl acetate extracts,respectively.Conclusions:The extract of S.cumini has acaricidal acivity against T.urticae,and the ethanol extract is the most efficient. | Abd El-Moneim MR Afify Hossam S El-Beltagi Sayed A Fayed Emad A Shalaby | 2011 | Asian Pacific Journal of Tropical Biomedicine2011，1，5： | 5 |
| 3 | Survival and outcomes for co-infection of chronic hepatitis C with and without cirrhosis and COVID-19: A multicenter retrospective study显示文摘BACKGROUND Chronic liver disease,particularly cirrhosis,is associated with worse outcomes in patients infected with coronavirus disease 2019(COVID-19).AIM To assess outcomes of COVID-19 infection among patients with pre-existing hepatitis C with or without liver cirrhosis.METHODS This multicenter,retrospective cohort study included all cases of confirmed coinfection of severe acute respiratory syndrome coronavirus 2 and chronic hepatitis C with or without liver cirrhosis who were admitted to six hospitals(Al-Sahel Hospital,Al-Matareya Hospital,Al-Ahrar Hospital,Ahmed Maher Teaching Hospital,Al-Gomhoreya Hospital,and the National Hepatology and Tropical Medicine Research Institute)affiliated with the General Organization for Teaching Hospitals and Institutes in Egypt.Patients were recruited from May 1,2020,to July 31,2020.Demographic,laboratory,imaging features,and outcomes were collected.Multivariate regression analysis was performed to detect factors affecting mortality.RESULTS This retrospective cohort study included 125 patients with chronic hepatitis C and COVID-19 co-infection,of which 64(51.20%)had liver cirrhosis and 40(32.00%)died.Fever,cough,dyspnea,and fatigue were the most frequent symptoms in patients with liver cirrhosis.Cough,sore throat,fatigue,myalgia,and diarrhea were significantly more common in patients with liver cirrhosis than in noncirrhotic patients.There was no difference between patients with and without cirrhosis regarding comorbidities.Fifteen patients(23.40%)with liver cirrhosis presented with hepatic encephalopathy.Patients with liver cirrhosis were more likely than non-cirrhotic patients to have combined ground-glass opacities and consolidations in CT chest scans:28(43.75%)vs 4(6.55%),respectively(P value<0.001).These patients also were more likely to have severe COVID-19 infection,compared to patients without liver cirrhosis:29(45.31%)vs 11(18.04%),respectively(P value<0.003).Mortality was higher in patients with liver cirrhosis,compared to those with no cirrhosis:33(51.56%)vs 9(14.75%),respectively(P value<0.001).All patients in Child-Pugh class A recovered and were discharged.Cirrhotic mortality occurred among decompensated patients only.A multivariate regression analysis revealed the following independent factors affecting mortality:Male gender(OR 7.17,95%CI:2.19–23.51;P value=0.001),diabetes mellitus(OR 4.03,95%CI:1.49–10.91;P value=0.006),and liver cirrhosis(OR 1.103,95%CI:1.037–1.282;P value<0.0001).We found no differences in liver function,COVID-19 disease severity,or outcomes between patients who previously received direct-acting antiviral therapy(and achieved sustained virological response)and patients who did not receive this therapy.CONCLUSION Patients with liver cirrhosis are susceptible to higher severity and mortality if infected with COVID-19.Male gender,diabetes mellitus,and liver cirrhosis are independent factors associated with increased mortality risk. | Shimaa Afify Basem Eysa Fatma Abdel Hamid Omnia M Abo-Elazm Mohamed A Edris Rabab Maher Ahmed Abdelhalim Muhammad Mostafa Abdel Ghaffar Dalia A Omran Hend Ibrahim Shousha | 2021 | World Journal of Gastroenterology2021，27，42： | 2 |
