1Protective effect of naringenin on acetic acid-induced ulcerative colitis in rats显示文摘AIM:To evaluate the ameliorative effect of naringenin(NG)during ulcerative colitis(UC)in rats.METHODS:Rats were treated with three different doses(25,50 and 100 mg/kg per day)of NG and a single dose of mesalazine(MES,300 mg/kg per day)for seven days prior to ulcerative colitis induction by4%acetic acid(AA).Twenty four hours after AA rectal administration,animals were scarified and the colonic tissues were dissected.Colonic mucus content was estimated using Alcian blue dye binding technique.In colon tissues,levels of total glutathione sulphadryls(T-GSH),non-protein sulphadryls(NP-SH)and thiobarbituric acid reactive substances(TBARS)were evaluated.The activities of the antioxidant enzymes,catalase(CAT)and superoxide dismutase(SOD)were measured.Concentrations of nucleic acids(DNA and RNA)and total protein were also estimated in colon tissues.Colonic levels of tumor necrosis factor-(TNF-),interleukin-1(IL-1),interleukin-6(IL-6),prostaglandin E2(PGE2)and nitric oxide(NO)were estimated.In cross section of colitis tissue the histopathological changes were observed.RESULTS:Colonic mucus content was decreased in AA compared to controls(587.09±65.59 mg/kg vs941.78±68.41 mg/kg,P<0.001).AA administration markedly reduced T-GSH(5.25±0.37 nmol/L vs 3.04±0.24 nmol/L,P<0.01),NP-SH(3.16±0.04 nmol/L vs 2.16±0.30 nmol/L,P<0.01),CAT(6.77±0.40 U/mg vs 3.04±0.2 U/mg,P<0.01)and SOD(3.10±0.11U/mg vs 1.77±0.18 U/mg,P<0.01)while TBARS,TNF-,IL-1,IL-6,PGE2 and NO levels(15.09±3.84nmol/L vs 59.90±16.34 nmol/L,P<0.01;113.56±1.91 pg/mg vs 134.24±4.77 pg/mg,P<0.01;209.20±36.38 pg/mg vs 422.19±31.47 pg/mg,P<0.01;250.83±25.09 pg/mg vs 638.58±115.9 pg/mg,P<0.01;248.19±36.98 pg/mg vs 541.74±58.34 pg/mg,P<0.01 and 81.26±2.98 mmol/g vs 101.90±10.73 mmol/g,P<0.001)were increased in colon of rats with UC compared controls respectively.Naringenin supplementation,significantly and dose dependently increased the colonic mucus content.The elevated TBARS levels were significantly decreased(39.35±5.86nmol/L,P<0.05;26.74±3.17 nmol/L,P<0.01 nmol/L and 17.74±2.69 nmol/L,P<0.01)compared to AA(59.90±16.34 nmol/L)group while the decreased levels of T-GSH and NP-SH and activities of CAT and SOD found increased by NG treatments in dose dependent manner.The decreased values of nucleic acids and total protein in AA group were also significantly(P<0.01)increased in all three NG supplemented groupsrespectively.NG pretreatment inhibited the TNF-levels(123.76±3.76 pg/mg,122.62±3.41 pg/mg and121.51±2.61 pg/mg vs 134.24±4.78 pg/mg,P<0.05)compared to AA group,respectively.Interleukins,IL-1 and IL-6 levels were also decreased in NG50+AA(314.37±16.31 pg/mg and 292.58±23.68 pg/mg,P<0.05)and NG100+AA(416.72±49.62 pg/mg and 407.96±43.87 pg/mg,P<0.05)when compared to AA(352.46±8.58 pg/mg and 638.58±115.98pg/mg)group.Similar decrease(P<0.05)was seen in PGE2and NO values when compared to AA group.The group pretreated with MES,as a reference drug,showed significant(P<0.01)protection against the changes induced in colon tissue by AA administration respectively.CONCLUSION:In present study,NG produced antioxidant and anti-inflammatory effects demonstrating protective effect in inflammatory bowel disease.Salim S Al-Rejaie Hatem M Abuohashish Maher M Al-Enazi Abdullah H Al-Assaf Mihir Y Parmar Mohammed M Ahmed 2013World Journal of Gastroenterology2013,19,34:20
2Progression of diethylnitrosamine-induced hepatic carcinogenesis in carnitine-depleted rats显示文摘AIM:To investigate whether carnitine deficiency is a risk factor during the development of diethylnitrosamine (DENA)-induced hepatic carcinogenesis. METHODS:A total of 60 male Wistar albino rats were divided into six groups with 10 animals in each group.Rats in group 1(control group)received a single intraperitoneal(i.p.)injection of normal saline. Animals in group 2(carnitine-supplemented group) were given L-carnitine(200 mg/kg per day)in drinking water for 8 wk.Animals in group 3(carnitine-depleted group)were given D-carnitine(200 mg/kg per day)and mildronate(200 mg/kg per day)in drinking water for 8 wk.Rats in group 4(DENA group)were injected with a single dose of DENA(200 mg/kg,i.p.)and 2 wk later received a single dose of carbon tetrachloride(2 mL/kg) by gavage as 1:1 dilution in corn oil.Animals in group 5(DENA-carnitine depleted group)received the same treatment as group 3 and group 4.Rats in group 6 (DENA-carnitine supplemented group)received the same treatment as group 2 and group 4.RESULTS:Administration of DENA resulted in a significant increase in alanine transaminase(ALT), gamma-glutamyl transferase(G-GT),alkaline phosphatase(ALP),total bilirubin,thiobarbituric acid reactive substances(TBARS)and total nitrate/ nitrite(NOx)and a significant decrease in reduced glutathione(GSH),glutathione peroxidase(GSHPx), catalase(CAT)and total carnitine content in liver tissues.In the carnitine-depleted rat model,DENA induced a dramatic increase in serum ALT,G-GT,ALP and total bilirubin,as well as a progressive reduction in total carnitine content in liver tissues.Interestingly, L-carnitine supplementation resulted in a complete reversal of the increase in liver enzymes,TBARS and NOx,and a decrease in total carnitine,GSH,GSHPx, and CAT induced by DENA,compared with the control values.Histopathological examination of liver tissues confirmed the biochemical data,where L-carnitine prevented DENA-induced hepatic carcinogenesis while D-carnitine-mildronate aggravated DENA-induced hepatic damage. CONCLUSION:Data from this study suggest for the first time that:(1)carnitine deficiency is a risk factor and should be viewed as a mechanism in DENA- induced hepatic carcinogenesis;(2)oxidative stress plays an important role but is not the only cause of DENA-induced hepatic carcinogenesis;and(3) long-term L-carnitine supplementation prevents the development of DENA-induced liver cancer.Salim S Al-Rejaie Abdulaziz M Aleisa Abdulaziz A Al-Yahya Saleh A Bakheet Abdulmalik Alsheikh Amal G Fatani Othman A Al-Shabanah Mohamed M Sayed-Ahmed 2009World Journal of Gastroenterology2009,15,11:4

4Lipoprotein abnormalities in South Asians and its association with cardiovascular disease:Current state and future directions显示文摘South Asians have a high prevalence of coronary heart disease(CHD) and suffer from early-onset CHD compared to other ethnic groups. Conventional risk factors may not fully explain this increased CHD risk in this population. Indeed, South Asians have a unique lipid profile which may predispose them to premature CHD. Dyslipidemia in this patient population seems to be an important contributor to the high incidence of coronary atherosclerosis. The dyslipidemia in South Asians is characterized by elevated levels of triglycerides, low levels of high-density lipoprotein(HDL) cholesterol, elevated lipoprotein(a) levels, and a higher atherogenic particle burden despite comparable low-density lipoprotein cholesterol levels compared with other ethnic subgroups. HDL particles also appear to be smaller, dysfunctional, and proatherogenic in South Asians. Despite the rapid expansion of the current literature with better understanding of the specific lipid abnormalities in this patient population, studies with adequate sample sizes are needed to assess the significance and contribution of a given lipid parameter on overall cardiovascular risk in this population. Specific management goals and treatment thresholds do not exist for South Asians because of paucity of data. Current treatment recommendations are mostly extrapolated from Western guidelines. Lastly, large, prospective studies with outcomes data are needed to assess cardiovascular benefit associated with various lipid-lowering therapies(including combination therapy) in this patient population.Ozlem Bilen Ayeesha Kamal Salim S Virani 2016World Journal of Cardiology2016,8,3:3
5Current systematic reviews and meta-analyses of COVID-19显示文摘BACKGROUND Coronavirus disease 2019(COVID-19)has left a significant impact on the world's health,economic and political systems;as of November 20,2020,more than 57 million people have been infected worldwide,with over 1.3 million deaths.While the global spotlight is currently focused on combating this pandemic through means ranging from finding a treatment among existing therapeutic agents to inventing a vaccine that can aid in halting the further loss of life.AIM To collect all systematic reviews and meta-analyses published related to COVID-19 to better identify available evidence,highlight gaps in knowledge,and elucidate further meta-analyses and umbrella reviews that are yet to be performed.METHODS We explored studies based on systematic reviews and meta-analyses with the keyterms,including severe acute respiratory syndrome(SARS),SARS virus,coronavirus disease,COVID-19,and SARS coronavirus-2.The included studies were extracted from Embase,Medline,and Cochrane databases.The publication timeframe of included studies ranged between January 01,2020,to October 30,2020.Studies that were published in languages other than English were not considered for this systematic review.The finalized full-text articles are freely accessible in the public domain.RESULTS Searching Embase,Medline,and Cochrane databases resulted in 1906,669,and 19 results,respectively,that comprised 2594 studies.515 duplicates were subsequently removed,leaving 2079 studies.The inclusion criteria were systematic reviews or meta-analyses.860 results were excluded for being a review article,scope review,rapid review,panel review,or guideline that produced a total of 1219 studies.After screening articles were categorized,the included articles were put into main groups of clinical presentation,epi-demiology,screening and diagnosis,severity assessment,special populations,and treatment.Subsequently,there was a second subclassification into the following groups:gastrointestinal,cardiovascular,neurological,stroke,thrombosis,anosmia and dysgeusia,ocular manifestations,nephrology,cutaneous manifestations,D-dimer,lymphocyte,anticoagulation,antivirals,convalescent plasma,immunosuppressants,corticosteroids,hydroxychloroquine,renin-angiotensin-aldosterone system,technology,diabetes mellitus,obesity,pregnancy,children,mental health,smoking,cancer,and transplant.CONCLUSION Among the included articles,it is clear that further research is needed regarding treatment options and vaccines.With more studies,data will be less heterogeneous,and statistical analysis can be better applied to provide more robust clinical evidence.This study was not designed to give recommendations regarding the management of COVID-19.Mahmoud Nassar Nso Nso Mostafa Alfishawy Anastasia Novikov Salim Yaghi Luis Medina Bahtiyar Toz Sofia Lakhdar Zarwa Idrees Yungmin Kim Dawa Ongyal Gurung Raheel S Siddiqui David Zheng Mariam Agladze Vikram Sumbly Jasmine Sandhu Francisco Cuevas Castillo Nadya Chowdhury Ravali Kondaveeti Sakil Bhuiyan Laura Guzman Perez Riki Ranat Carlos Gonzalez Harangad Bhangoo John Williams Alaa Eldin Osman Joyce Kong Jonathan Ariyaratnam Mahmoud Mohamed Ismail Omran Mariely Lopez Akwe Nyabera Ian Landry Saba Iqbal Anoosh Zafar Gondal Sameen Hassan Ahmed Daoud Bahaaeldin Baraka Theo Trandafirescu Vincent Rizzo 2021World Journal of Virology2021,10,4:2
