1. EFFICACY ANALYSIS OF ENDOSCOPIC SUBMUCOSAL DISSECTION FOR THE EARLY GASTRIC CANCER AND PRECANCEROUS LESIONS
RESUMO Contexto: O tratamento endoscópico das lesões pré-cancerosas e do câncer gástrico precoce tem sido amplamente aceito nos últimos anos. A dissecção endoscópica da submucosa (submucosectomia), obedecendo a critérios estabelecidos de indicação, pode levar a cura da doença em mais de 90% dos casos. Objetivo: Este estudo teve como objetivo a

3. HELICOBACTER PYLORI INFECTION AND GASTRIC CANCER PRECURSOR LESIONS: PREVALENCE AND ASSOCIATED FACTORS IN A REFERENCE LABORATORY IN SOUTHEASTERN BRAZIL
RESUMO CONTEXTO: A infecção por Helicobacter pylori é o fator de risco mais importante para atrofia gástrica e metaplasia intestinal, ambas consideradas lesões precursoras do câncer gástrico. Portanto, a investigação da ocorrência de infecção por H. pylori, das lesões precursoras e dos fatores associados orienta a adoção de estratégias espe

5. Evaluation of Gastro-protective Activity of Myristica fragrans on Ethanol-induced Ulcer in Albino Rats
Abstract: Myristica fragrans seeds are traditionally used to treat dyspepsia, vomiting and abdominal pain. The purpose of this study was to investigate the protective effect of Myristica fragrans in ethanol induced gastric ulcer. Study was carried out on rats, divided into four groups; negative control, positive control, standard drug control, and Myristica

6. TARGETED AND NON-TARGETED ANALYSIS BASED ON ULTRA HIGH PERFORMANCE LIQUID CHROMATOGRAPHY AND FOURIER TRANSFORM INFRARED SPECTROSCOPY FOR PARIS SPECIES OF DIFFERENT GEOGRAPHICAL ORIGINS
Various species of Paris have been used in treatments for their antitumor, antimicrobial, hemostatic, anthelmintic and immune-stimulating properties, among others. The bioactive markers of these plants including paris saponins I (PSI), paris saponins II (PSII), paris saponins VI (PSVI) and paris saponins VII (PSVII) are responsible for inhibiting nasopharyng

7. CONVERSION THERAPY FOR GASTRIC CANCER: EXPANDING THE TREATMENT POSSIBILITIES
RESUMO Racional : A terapia de conversão no câncer gástrico (CG) é definida como o uso de quimio/radioterapia seguida de ressecção cirúrgica com intenção curativa de um tumor que era considerado irressecável ou oncologicamente incurável. Objetivo : Avaliar os resultados da terapia de conversão no tratamento do CG. Métodos : Análise ret

8. The role of high sensitive C-reactive protein and histopathological evaluation in chronic gastritis patients with or without Helicobacter pylori infection
Abstract Purpose: To evaluate serum levels of high-sensitivity C-reactive protein (hs-CRP) in chronic gastritis patients to predict Helicobacter pylori (HP) infection, inflammatory activity, and precancerous lesions. Methods: A total of 811 patients with upper gastrointestinal symptoms and histopathological diagnosis of chronic gastritis were enrolled in

9. Decreased mRNA Expression of Cystathionine Gamma lyase and H2S Concentration in Gastric Mucosal Tissue in Diabetic Rats
ABSTRACT Background and aim: It is well established that the rate of gastric lesions increases in diabetic rats. Recently, the protective effect of hydrogen sulfide (H2S) in gastric mucosa has been proven. This study aimed to determine the release of H2S and mRNA expression of cystathionine gamma lyase (CSE) in gastric mucosa in alloxan-diabetic rats in resp

10. Validation of classic and expanded criteria for endoscopic submucosal dissection of early gastric cancer: 7 years of experience in a Western tertiary cancer center
OBJECTIVE: Our aim was to evaluate the Japan Gastroenterological Endoscopy Society criteria for endoscopic submucosal resection of early gastric cancer (EGC) based on the experience in a Brazilian cancer center. METHODS: We included all patients who underwent endoscopic submucosal resection for gastric lesions between February 2009 and October 2016. Demogr

11. COX-2 gene expression and methylation profile in Sapajus apella as an experimental model for gastric adenocarcinoma
Abstract Gastric cancer (GC) remains one of the main causes of cancer-related death worldwide. There are two distinct histological types of GC: diffuse and intestinal. The latter is characterized by the presence of pre-neoplastic lesions. One of the most frequently altered enzymes in intestinal GC is COX-2, an important lesion marker. This work aimed to stud

12. Screening and characterization of lactic acid bacterial strains that produce fermented milk and reduce cholesterol levels
ABSTRACT Objective To screen for and characterize lactic acid bacteria strains with the ability to produce fermented milk and reduce cholesterol levels. Methods The strains were isolated from traditional fermented milk in China. In vitro and in vivo evaluation of cholesterol-reduction were used to identify and verify strains of interest. Characteristics we
