PURPOSE Colorectal carcinogenesis is thought to be related to abdominal obesity and insulin resistance. To investigate whether visceral fat accumulation contributes to colorectal carcinogenesis, we examined its accumulation and the levels of the adipose tissue-derived hormone adiponectin in Japanese patients with colorectal adenoma. EXPERIMENTAL DESIGN(More)
AIM To investigate the association between adiponectin levels and risk of colorectal adenoma and cancer (early and advanced). METHODS A cross-sectional study in a cohort of hospital-based patients was conducted between January 2004 and March 2006 at Yamagata University Hospital. Male subjects, who had colorectal tumors detected by endoscopic examination,(More)
Increased oxidative stress is generally thought to be associated with tumorigenesis. In this cross-sectional study, we evaluated plasma 8-hydroxydeoxyguanosine (8-OHdG) levels in patients with colorectal adenoma and cancer, as a surrogate marker of oxidative damage to deoxyribonucleic acid (DNA). We collected blood samples from 58 patients with adenoma, 32(More)
Musashi-1 (Msi-1), an RNA-binding protein, had been proposed to be a specific marker for neural stem/precursor cells. Msi-1 expressing cells in the intestinal epithelium are also strongly considered as potential stem/precursor cells. To clarify the behavior of those cells in the injury or regeneration phase, we investigated Msi-1 expressing cells of(More)
Granulocyte and monocyte adsorption apheresis (GCAP) is a useful strategy for intractable ulcerative colitis, but its mechanisms of therapy is not fully explained. Previously, depleting activated granulocytes and monocytes (GMs) and modifying product of proinflammatory cytokines had been proposed. In addition, activated GMs are releasing anti-inflammatory(More)
Anaphylatoxins, which are involved in both pro-inflammatory processes and a variety of anti-inflammatory effects, are produced during granulocyte and monocyte adsorptive apheresis. We noticed the anti-inflammatory effects of C5a, the strongest anaphylatoxin, in granulocyte and monocyte adsorptive apheresis. The aim of this study was to investigate the(More)
We reported 3 cases of the uncommon type of persistent gastrointestinal bleeding during anticoagulation therapy due to cardiovascular disorders or collagen disease. Endoscopic observation showed non pulsatile active bleeding from apparently normal mucosa, without any ulcer or obvious vascularectasia. The outflow of bleeding was string-like and continuous.(More)
Primary orbital adenocarcinoma is very rare. There are not any reports about the treatment of this disease, except for surgery. We experienced a case of primary orbital adenocarcinoma, which we successfully treated by chemoradiation using 5-FU and cisplatin. It is very important to collect and record cases of rare diseases responding to certain chemotherapy(More)
