Background And Objective: Rifaximin is used to treat diarrhea-predominant irritable bowel syndrome (IBS-D). However, determining the most effective regimen remains a challenge. This study aimed to evaluate the effectiveness and safety of a 10-day high-dose course of rifaximin (2200 mg/day) and its effects on both abdominal symptoms and quality of life (QOL) in patients with IBS-D.

Background: Colorectal cancer (CRC) is a very common cancer worldwide. CRC is characterized by some changes in the expression of oncogenic and tumor suppressor genes. These changes are associated with dysregulation of non-coding RNAs, including long non-coding RNAs (lncRNAs).

Recent evidence shows the beneficial effects of Baltic Sea diet score (BSDS) and healthy Nordic diet index (HNDI) on chronic diseases, however, there is no evidence to investigate them on the risk of non-alcoholic fatty liver disease (NAFLD). The purpose of this study was to investigate the associations between BSDS and HNDI with the risk of NAFLD. In this case-control study, 552 people in good health and 340 people with NAFLD over the age of 18 took part.

Long non-coding RNAs (lncRNAs) play a significant biological role in the regulation of various cellular processes such as cell proliferation, differentiation, apoptosis and migration. In various malignancies, lncRNAs interplay with some main cancer-associated signaling pathways, including the Hippo signaling pathway to regulate the various cellular processes. It has been revealed that the cross-talking between lncRNAs and Hippo signaling pathway involves in gastrointestinal (GI) cancers development and progression.

The role of numerous risk factors, including consumption of alcohol, smoking, having diet high in fat and sugar and many other items, on caner progression cannot be denied. Viral diseases are one these factors, and they can initiate some signalling pathways causing cancer. For example, they can be effective on providing oxygen and nutrients by inducing VEGF expression.

Background: Metabolic-associated fatty liver disease (MAFLD) is defined by fatty liver combined with a disturbed metabolic state. Mediterranean diet (MedDiet) contains anti-inflammatory, anti-oxidative, and anti-fibrotic components and is seemingly beneficial in the management of MAFLD. We aimed to evaluate the correlation between adherence to MedDiet and the severity of MAFLD.

Introduction And Importance: Surgeons may mistakenly consider the right hepatic duct as cystic duct, ligate, and divide it.

Case Presentation: A 58-year-old woman presented with right upper quadrant (RUQ) abdominal pain, nausea, and RUQ tenderness, but negative Murphy's sign. Common bile duct was 10 mm based on abdominal ultrasound.

Background: The promoter -1082 A/G (rs1800896) polymorphism of Interleukin-10 (IL-10) gene have been widely reported and considered to have a significant role on gastric cancer risk, but the results are inconsistent.

Objective: To clarify the association, we conducted a meta-analysis to investigate the associations IL-10 -1082 A/G polymorphism with gastric cancer.

Methods: Eligible articles were identified by searching databases including PubMed, Web of Science, and Google Scholar up to August 03, 2017.

Background: several epidemiological studies have suggested that polymorphisms of the Excision Repair Cross Complementing Group-5 (ERCC5) gene might be related to gastric cancer risk; however, the results have been inconsistent or controversial. Therefore, we have performed a systematic review and meta-analysis to clarify the association between the ERCC5 gene polymorphisms and gastric cancer risk. Materials and Methods: An electronic search was conducted of several databases, including PubMed, Web of Science, and Google Scholar for articles that describe the association between polymorphisms of the ERCC5 gene and susceptibility of gastric cancer.

Background: Many studies have reported associations of the X-ray repair cross-complementing group 3 (XRCC3) Thr241Met polymorphism with colorectal cancer (CRC) risk, but the results remained controversial. Hence, we performed the present meta-analysis with different inheritance models.

Materials And Methods: We searched the PubMed and Google scholar databases for studies relating to associations between XRCC3 Thr241Met polymorphism and risk of CRC.
