Interleukin 12B mRNA level and rs3212227 genotyping in peripheral blood mononuclear cells of inflammatory bowel disease patients.

Background/aim: Inflammatory bowel disease (IBD) is a multifactorial disorder. Single nucleotide polymorphisms (SNPs) in the IL-12 gene, which are the main factors to regulate the immune reaction, play an important role in the production of IL-12 molecules. The aim of this study was to evaluate the correlation between the SNP on position +1188 of the 3 ′ UTR region of the IL-12 p40 subunit gene and expression of the IL-12 p40 gene.

Lack of BRAFV600E mutation in stage I and II of colorectal cancer.

Aim: We aimed to explore the frequency of BRAFV600E mutation in Iranian patients with colorectal cancer (CRC) as well as its association with clinic pathological characteristic of patients.

Background: CRC is the third leading cause of cancer related death. There is a growing body of data showing the association of BRAFV600E mutation with malignant transformation and clinical outcome of different tumors, including CRC.

Association between two single base polymorphisms of intercellular adhesion molecule 1 gene and inflammatory bowel disease.

Aim: The present study evaluated the association between G241R and K469E polymorphisms of intercellular adhesion molecule 1 gene and inflammatory bowel disease in Iranian population.

Background: Inflammatory bowel disease including ulcerative colitis and Crohn's disease, is a chronic idiopathic inflammatory disease of the gastrointestinal tract. There are two single base polymorphisms of intercellular adhesion molecule 1gene, G241R and K469E, reported to be associated with inflammatory disorders.

Evaluation of insulin like growth facror-1 genetic polymorphism with gastric cancer susceptibility and clinicopathological features.

Gastric cancer (GC) is one of the most common malignancies in the world. It is the first cause of cancer deaths in both sexes In Iranian population. Circulating insulin-like growth factor-one (IGF-1) levels have been associated for gastric cancer.

Biliary cast syndrome in an opium inhaler.

Biliary cast syndrome (BCS) is an uncommon complication which is mostly described in orthotopic liver transplantation. However, BCS has also been reported rarely in non-liver transplant patients. We describe a male long-term opium inhaler with BCS who underwent successful endoscopic cast removal by balloon enteroscopy-guided endoscopic retrograde cholangiopancreatography.
