We investigated the trace element status in Crohn's disease (CD) patients receiving enteral nutrition, and evaluated the effects of trace element-rich supplementation. Thirty-one patients with CD were enrolled in this study. All patients were placed on an enteral nutrition regimen with Elental(R) (Ajinomoto pharmaceutical. Ltd., Tokyo, Japan). Serum(More)
We investigated energy expenditure in hospitalized patients with Crohn's disease (CD), and determined optimal energy requirements for nutritional therapy. Sixteen patients (5 women and 11 men, mean age 36 year old, mean BMI 18.7 kg/m(2)) and 8 healthy volunteers were enrolled in this study. Measured resting energy expenditure (mREE) levels were determined(More)
Interleukin (IL)-32 is a recently described proinflammatory cytokine, characterized by the induction of nuclear factor (NF)-kappaB activation. We studied IL-32alpha expression in human pancreatic periacinar myofibroblasts, which play important roles in the regulation of extracellular matrix metabolism and inflammatory responses in the pancreas. IL-32alpha(More)
We investigated the energy expenditure in hospitalized patients with severe or moderate ulcerative colitis (UC), and compared them to healthy controls. Thirteen patients (5 women and 8 men; mean age 31.8 years; mean BMI 19.0 kg/m(2)) and 10 healthy volunteers were enrolled in this study. The resting energy expenditure (mREE) levels were determined by(More)
Cellobiose is produced from cellulose using specific bacterial enzymes, and is hydrolyzed into glucose by the enzymes cellobiosidase and cellulase. In this study, we examined the effects of cellobiose on colonic mucosal damage in a dextran sulfate sodium (DSS) colitis model. BALB/c mice were divided into two groups. In the first group, the mice were fed(More)
It is suspected that early gastric carcinoma (GC) is a dormant variant that rarely progresses to advanced GC. We demonstrated that the dormant and aggressive variants of tubular adenocarcinomas (TUBs) of the stomach are characterized by loss of MYC and gain of TP53 and gain of MYC and/or loss of TP53, respectively. The aim of this study is to determine(More)
The gut microbiota plays a significant role in the pathogenesis of Crohn's disease (CD). In this study, we analyzed the disease activity and associated fecal microbiota profiles in 160 CD patients and 121 healthy individuals. Fecal samples from the CD patients were collected during three different clinical phases, the active (n=66), remission-achieved(More)
We investigated the effects of treatment with antibodies against tumor necrosis factor (TNF)-α on energy metabolism, nutritional status, serum cytokine levels in patients with Crohn's disease (CD). Twelve patients were enrolled. Resting energy expenditure (REE) levels were measured by indirect calorimetry. Crohn's disease activity index (CDAI) significantly(More)
Leukocytapheresis (LCAP) has been advocated as a treatment for moderate to severe active ulcerative colitis (UC) in Japan. To clarify the predictive factors for a rapid response to LCAP treatment, we conducted a multicenter prospective open-label study. A total of 105 patients with UC were analyzed. LCAP was performed using a Cellsorba EX column once a week(More)
OBJECTIVE In undifferentiated-type gastric carcinoma (UGC), inactivation of TP53 is infrequent at early stages and comparable to tubular adenocarcinomas (TUBs) at advanced stages. To clarify how TP53 inactivation relates to histogenesis of UGCs, we examined p53 alterations in multiple samples of individual UGCs. METHODS We used 27 UGCs including 12 mixed(More)
