BackgroundFunctional dyspepsia is the main cause of upper abdominal discomfort affecting 5-10% of the world population. Despite various therapeutic approaches, up to 50% of patients with functional dyspepsia seek alternative treatments. In the present study we evaluated the effect of curcumin supplementation along with famotidine therapy on severity of functional dyspepsia.

Our study aimed to describe the clinical characteristics and outcomes of COVID-19 infection among patients with underlying liver diseases and determine the risk factors for severe COVID-19 among them. In a retrospective analytical study, 1002 patients with confirmed COVID-19 pneumonia were divided into two groups: patients with and without underlying liver diseases.
View Article and Find Full Text PDFAberrant DNA methylation has been investigated in carcinogenesis and as biomarker for the early detection of colorectal cancer (CRC). The present study aimed to define the methylation status in the regulatory elements of two proapoptotic genes, Fas cell surface death receptor (FAS) and BCL2-associated X protein (BAX). DNA methylation analysis was performed in tumor and adjacent normal tissue using II/I restriction digestion and methylation-specific polymerase chain reaction (PCR).

Therefore, we aimed to evaluate the frequency distribution of GERD symptoms among the individuals with mild respiratory disorder due to the past history of toxic fume exposure to sulfur mustard (SM).
Materials And Methods: In a historical cohort study, subjects were randomly selected from 7000 patients in a database of all those who had a history of previous exposure to a single high dose of SM gas during war.
Aim: Human papillomaviruses (HPV) have frequently been detected in colorectal cancer tumor samples, and may play a role in the pathogenesis of colorectal cancer. This study was designed to investigate the presence of DNA and RNA for the high-risk HPV genotypes 16 and 18 in samples of colorectal cancer tumors and adjacent normal tissues. We also investigated the expression of proapoptotic genes in HPV-positive colorectal tumors compared to normal tissue samples.

Introduction: Using lengthening over an intramedullary nail as a technique for cosmetic purposes improves the individuals' quality of life and provides more satisfactory results due to less external fixator period.
Methods: This study reports a case series of 143 individuals who underwent bilateral tibial lengthening over an intramedullary nail for cosmetic purposes together with the review of parameters related to the surgery and complications. Level of satisfaction was measured with the standard visual analog scale at least 1 year after removal of external fixator.
Background: The association of gastro-esophageal reflux (GER) with a wide variety of pulmonary disorders was recognized. We aimed to evaluate the effect of GER-induced esophagitis on airway hyper-reactivity (AHR) in patients and the response to treatment.
Materials And Methods: In this cohort study, 30 patients attending the gastrointestinal clinic of a university hospital with acid reflux symptoms were included.
Carcinogenesis and resistance to chemotherapy could be as results of expression variations in apoptosis regulating genes. Changes in the expression of apoptosis interfering genes may contribute to colorectal carcinogenesis and resistance to 5-Flourouracil (5-FU) during treatment schedule period. The present study aimed to evaluate the expression of pro-apoptotic and anti-apoptotic genes in colorectal cancer tumor tissues, normal adjacent tissues, and tumor colorectal cancer cell line during acquiring resistance to 5-FU in HT-29 based on Bolus treatment protocol.

Background/aim: Gastro-esophageal reflux has been suggested to be associated with several pulmonary complications such as asthma, and post-transplant bronchiolitis obliterans (BO). Pepsin or bile salts in the sputum is shown to be an optimal molecular marker of gastric contents macro/micro aspiration. In this study, we investigated sputum pepsin as a marker of micro-aspiration in sulfur mustard (SM) exposed cases compared to healthy controls.

Case Presentation: We present a rare case of a 49-year-old woman presenting with persistent nausea and vomiting for 20 days.
Introduction: Several factors have been suggested to account for differences in the virulence of Helicobacter pylori infections in various populations. Evidence suggests the existence of different strains of H. pylori with different degrees of virulence.
View Article and Find Full Text PDFBackground: The association of Helicobacterpylori with peptic ulcer disease, atrophic gastritis, gastric adenocarcinoma, MALT (mucosa associated lymphoid tissue) lymphoma is well recognized.
Aim: This study was conducted to see whether there was any relation between H. pylori eradication and reflux esophagitis in Iran.
Background: The prevalence of Helicobacter pylori infection varies in different societies and geographical locations. This is attributed to socioeconomic status, life style, family density and other factors. There is also a possibility of an association between eating habits and the prevalence of H.
View Article and Find Full Text PDFBackground And Aim: Ulcerative colitis (UC) is a multifactorial disease associated with dysregulated immunity. Recently, cytotoxic T lymphocyte associated antigen 4 (CTLA-4) gene polymorphisms have been reported in association with several autoimmune diseases in several populations. In the present study, the possible implication of the CTLA-4 gene as a risk factor for UC in the Iranian population was investigated.
