Background: Obesity and () infection are public health problems in the world and Iran. This study aimed to indicate the anatomical place with the most accurate results for . According to gastric mapping, this study will be able to evaluate the prevalence of based on the pathology of gastric mapping and the accuracy of the antral rapid urease test (RUT) based on endoscopic findings.

Profiling of novel circulating microRNAs as a non-invasive biomarker in diagnosis and follow-up of high and low-grade gliomas.

Objective: Glioblastoma (GBM) is the most common primary malignant neoplasm of the central nervous system (CNS). Despite the progress in therapeutic strategies such as surgical techniques, radiotherapy, chemotherapy, and targeted therapy, prognosis and therapeutically convenient monitoring tools in patients with GBM has not improved significantly up to now.Therefore, exosomal miRNAs as novel non-invasive biomarkers having high sensitivity and specificity are required to improve diagnosis and to develop new targeted therapy strategies for GBM patients.

CD44 epithelial isoform inversely associates with invasive characteristics of colorectal cancer.

There is no consensus regarding the clinical significance of CD44 and CD24 as cancer stem cell (CSC) marker in colorectal cancer (CRC). A total of 494 CRC samples (2008-2017) were assessed for CD44 (epithelial isoform) and CD24 expression using tissue microarray. CD24 individually or in combination with CD44 was not associated with any of the clinicopathologic characteristics of the tumor.

Prognostic Value of Lymph Node Ratio in Comparison to Lymph Node Metastases in Stage III Colon Cancer.

Background & Objectives: Colon cancer is currently of high incidence and mortality rate. Identifying the factors influencing its prognosis can be very beneficial to its clinical treatment. Recent studies have shown that lymph nodes ratio can be considered as an important prognostic factor.

Severe diarrhea due to Isospora belli in a patient with thymoma.

Opportunistic isosporidial infection of the gastrointestinal tract is frequently encountered in patients with acquired immunodeficiency syndrome (AIDS) and is considered to be an AIDS-defining illness. Chronic severe watery diarrhea due to Isospora belli has also been reported in other immunodeficiency states. This report describes severe chronic debilitating diarrhea due to isosporiasis in a patient with mediastinal thymoma, a common tumor of the anterior mediastinum, originating from the epithelial cells of the thymus.
