| 1 | Pathogenesis and clinical management of Helicobacter pylori gastric infection显示文摘Helicobacter pylori(H.pylori)is a gram-negative bacterium that infects approximately 4.4 billion individuals worldwide.However,its prevalence varies among different geographic areas,and is influenced by several factors.The infection can be acquired by means of oral-oral or fecal-oral transmission,and the pathogen possesses various mechanisms that improve its capacity of mobility,adherence and manipulation of the gastric microenvironment,making possible the colonization of an organ with a highly acidic lumen.In addition,H.pylori presents a large variety of virulence factors that improve its pathogenicity,of which we highlight cytotoxin associated antigen A,vacuolating cytotoxin,duodenal ulcer promoting gene A protein,outer inflammatory protein and gamma-glutamyl transpeptidase.The host immune system,mainly by means of a Th1-polarized response,also plays a crucial role in the infection course.Although most H.pylori-positive individuals remain asymptomatic,the infection predisposes the development of various clinical conditions as peptic ulcers,gastric adenocarcinomas and mucosa-associated lymphoid tissue lymphomas.Invasive and non-invasive diagnostic methods,each of them with their related advantages and limitations,have been applied in H.pylori detection.Moreover,bacterial resistance to antimicrobial therapy is a major challenge in the treatment of this infection,and new therapy alternatives are being tested to improve H.pylori eradication.Last but not least,the development of effective vaccines against H.pylori infection have been the aim of several research studies. | Breno Bittencourt de Brito Filipe Ant?nio Fran?a da Silva Aline Silva Soares Vinícius Afonso Pereira Maria Luísa Cordeiro Santos Mariana Miranda Sampaio Pedro Henrique Moreira Neves Fabrício Freire de Melo | 2019 | World Journal of Gastroenterology2019，25，37： | 84 |
| 2 | Helicobacter pylori infection: Beyond gastric manifestations显示文摘Helicobacter pylori(H.pylori)is a bacterium that infects more than a half of world’s population.Although it is mainly related to the development of gastroduodenal diseases,several studies have shown that such infection may also influence the development and severity of various extragastric diseases.According to the current evidence,whereas this bacterium is a risk factor for some of these manifestations,it might play a protective role in other pathological conditions.In that context,when considered the gastrointestinal tract,H.pylori positivity have been related to Inflammatory Bowel Disease,Gastroesophageal Reflux Disease,Non-Alcoholic Fatty Liver Disease,Hepatic Carcinoma,Cholelithiasis,and Cholecystitis.Moreover,lower serum levels of iron and vitamin B12 have been found in patients with H.pylori infection,leading to the emergence of anemias in a portion of them.With regards to neurological manifestations,a growing number of studies have associated that bacterium with multiple sclerosis,Alzheimer’s disease,Parkinson’s disease,and Guillain-Barrésyndrome.Interestingly,the risk of developing cardiovascular disorders,such as atherosclerosis,is also influenced by the infection.Besides that,the H.pylori-associated inflammation may also lead to increased insulin resistance,leading to a higher risk of diabetes mellitus among infected individuals.Finally,the occurrence of dermatological and ophthalmic disorders have also been related to that microorganism.In this sense,this minireview aims to gather the main studies associating H.pylori infection with extragastric conditions,and also to explore the main mechanisms that may explain the role of H.pylori in those diseases. | Maria Luisa Cordeiro Santos Breno Bittencourt de Brito Filipe Antonio França da Silva Mariana Miranda Sampaio Hanna Santos Marques Natalia Oliveira e Silva Dulciene Maria de Magalhaes Queiroz Fabricio Freire de Melo | 2020 | World Journal of Gastroenterology2020，26，28： | 34 |
| 3 | Chronic myeloid leukemia-from the Philadelphia chromosome to specific target drugs:A literature review显示文摘Chronic myeloid leukemia(CML)is a myeloproliferative neoplasm and was the first neoplastic disease associated with a well-defined genotypic anomaly―the presence of the Philadelphia chromosome.The advances in cytogenetic and molecular assays are of great importance to the diagnosis,prognosis,treatment,and monitoring of CML.The discovery of the breakpoint cluster region(BCR)-Abelson murine leukemia(ABL)1 fusion oncogene has revolutionized the treatment of CML patients by allowing the development of targeted drugs that inhibit the tyrosine kinase activity of the BCR-ABL oncoprotein.Tyrosine kinase inhibitors(known as TKIs)are the standard therapy for CML and greatly increase the survival rates,despite adverse effects and the odds of residual disease after discontinuation of treatment.As therapeutic alternatives,the subsequent TKIs lead to faster and deeper molecular remissions;however,with the emergence of resistance to these drugs,immunotherapy appears as an alternative,which may have a cure potential in these patients.Against this background,this article aims at providing an overview on CML clinical management and a summary on the main targeted drugs available in that context. | Mariana Miranda Sampaio Maria Luísa Cordeiro Santos Hanna Santos Marques Vinícius Lima de Souza Gonçalves Glauber Rocha Lima Araújo Luana Weber Lopes Jonathan Santos Apolonio Camilo Santana Silva Luana Kauany de SáSantos Beatriz Rocha Cuzzuol Quézia Estéfani Silva Guimarães Mariana Novaes Santos Breno Bittencourt de Brito Filipe Antônio França da Silva Márcio Vasconcelos Oliveira Cláudio Lima Souza Fabrício Freire de Melo | 2021 | World Journal of Clinical Oncology2021，12，2： | 3 |
| 4 | Resveratrol attenuates metabolic,sperm,and testicular changes in adult Wistar rats fed a diet rich in lipids and simple carbohydrates显示文摘High-fat diets affect male reproduction and sexual function.Therefore,we evaluated the effects of prolonged resveratrol administration on the metabolic,sperm,and testicular parameters of rats fed a cafeteria diet.Male Wistar rats were divided at weaning into control(Cv n=20)and cafeteria(CAF,n=16)groups.At 3 months,half of them were given daily supplementations of resveratrol(C-R,n=10;CAF-R,n=8)at a dosage of 30 mg kg-1 body mass for 2 months.Animals were killed at 5 months of age,and blood,spermatozoa,and testes were collected for further analysis.Data were analyzed by one-way ANOVA,and P<0.05 was considered statistically significant.The CAF diet promoted hyperglycemia(P<0.0001),and treatment with resveratrol reversed this condition(P<0.0001).The CAF diet reduced sperm viability and motility,while resveratrol improved these parameters(F<0.05).Regarding testicular morphology,the height of the seminiferous epithelium was reduced in the CAF group compared with that of the C group(P=0.0007).Spermatogenic cell proliferation was also reduced in the CAF group compared with that of the C group.However,the CAF-R showed an increase in cell proliferation rate compared with that of the untreated CAF group(P=0.0024).Although it did not modify body mass,the consumption of a CAF diet promoted hyperglycemia,adverse testicular morphology remodeling,and abnormal sperm,which were attenuated by treatment with resveratrol,thus suggesting a protective effect of this antioxidant on spermatogenesis. | Fabiana A de Oliveira Waldemar S Costa Francisco J B Sampaio Bianca M Gregorio | 2019 | Asian Journal of Andrology2019，21，2： | 2 |
