Abstract Background: Pulmonary involvement in ulcerative colitis (UC) is thought to be rare. There is not a definite document about the question that "Is the lung a target organ in inflammatory bowel disease?" The aim of the present study is to compare lung function between cases with UC and healthy controls. This study will also be of interest about searching the outbreak of pulmonary functio...

A general scheme for the synthesis of C8-arylpurine phosphoramidites has been developed. C8-Arylation of C8-bromo-2'-deoxyguanosine is the key step and has been achieved through the use of a Suzuki coupling. Since the coupling reaction is conducted under aqueous conditions, it is unnecessary to protect and then deprotect the hydroxyl groups, thus saving several steps and improving overall yield...

Background: Inflammatory bowel disease, an autoimmune disease, has two clinical manifestations including Crohn’s disease and ulcerative colitis (UC). IL-17 has been the target of intensive research in autoimmune diseases. The influence of Toll like receptor 4 (TLR-4) gene polymorphisms on IL-17 production has also been revealed in UC patients and tissue inflammation in mice. Objectives: To inve...

Background: Crohn’s disease (CD) and ulcerative colitis (UC) are two major clinical presentations of inflammatory bowel disease (IBD). Many novel candidate genes have been found to be associated with increased risk for IBD. Recently IL-23 receptor gene is identified as an IBD associated gene in genome-wide studies. Objective: To ascertain whether rs7517847 and rs1004819 SNPs in the IL-23 recept...

background: ulcerative colitis (uc) is a multi-factorial autoimmune disease. p-glycoprotein is encoded by the multidrug resistance 1 (mdr1) gene. the c3435t polymorphism in the mdr1 gene is correlated with low p-glycoprotein expression. additionally, vitamin d has regulatory effects on the immune system. the aim of our study was to determine the association between the c3435t mdr1 polymorphism ...
