Background: Understanding the molecular mechanisms of colorectal cancer has evolved during the last decade ushering the era of personalized medicine. Alteration of BRAF and PI3K is common in colorectal cancer, and can affect several signaling pathways including EGFR (epidermal growth factor receptor). The aim of this meta-analysis is to evaluate the clinical role of PI3K and BRAF mutations in patients with KRAS wild-type metastatic colorectal cancer (MCRC) receiving an EGFR monoclonal antibody (anti-EGFR) inhibitor as first-line therapy.

A complex etiology involving both environmental and genetic factors influences IBD pathogenesis. The role of microRNAs (miRNAs), noncoding RNAs involved in regulating numerous biological processes, to IBD pathology, in terms of initiation and progression, remains ill-defined.

Aim: To examine whether amoxicillin and high-dose dexlansoprazole would reliably achieve an H. pylori eradication rate of ≥90%.
Objective: Traditional Helicobacter pylori (H. pylori) eradication therapy has been undermined by increasing antimicrobial, especially clarithromycin, resistance. Susceptibility testing in some areas is difficult to achieve or unavailable.

Background And Aim: Helicobacter pylori infections have become increasingly difficult to treat as antimicrobial resistance has increased. The aim of this study was to test the hypothesis that a 6-week dual regimen of amoxicillin 1 gm and omeprazole 20 gm therapy b.i.
