Prostaglandin E2 (PGE2) is the major product of Cyclooxygenase-2 (COX-2) in colorectal cancer (CRC). We aimed to assess PGE2 cell surface receptors (EP 1–4) to examine the mechanisms by which PGE2 regulates tumour progression. Gene expression studies were performed by quantitative RT-PCR. Cell cycle was analysed by flow cytometry with cell proliferation(More)
Chemotherapy-induced diarrhea (CID) is a common and often severe side effect experienced by colorectal cancer (CRC) patients during their treatment. As chemotherapy regimens evolve to include more efficacious agents, CID is increasingly becoming a major cause of dose limiting toxicity and merits further investigation. Inflammation is a key factor behind(More)
BACKGROUND & AIMS The relationship between site of intestinal inflammation and primary sclerosing cholangitis (PSC) development in inflammatory bowel disease (IBD) has not been studied extensively, but may be important in understanding the pathogenesis of PSC. We aimed to determine patterns of disease distribution in IBD patients with and without PSC. (More)
BACKGROUND Recurrence of Crohn's disease is common after intestinal resection. A number of agents have been studied in controlled trials with the goal of reducing the risk of endoscopic or clinical recurrence of Crohn's disease following surgery. OBJECTIVES To undertake a systematic review of the use of medical therapies for the prevention of(More)
INTRODUCTION Adalimumab is a recombinant human IgG1 monoclonal antibody to TNF-alpha. There are limited data with regard to its efficacy in ulcerative colitis. We report experience of adalimumab in ulcerative colitis in a single centre with a focus on the ability of this agent to maintain response and avoid colectomy in the medium to long-term. METHODS(More)
BACKGROUND AND AIMS There is a high rate of stricturing post-operative recurrence in Crohn's disease (CD) particularly at sites of surgical anastomosis, and over 50% of these patients will require a repeat resection. Endoscopic dilatation of anastomotic strictures is an alternative to surgical resection in selected patients. We aimed to evaluate the safety(More)
BACKGROUND Body image refers to a person's sense of their physical appearance and body function. A negative body image self-evaluation may result in psychosocial dysfunction. Crohn's disease and ulcerative colitis are associated with disabling features, and body image dissatisfaction is a concern for many patients with inflammatory bowel disease (IBD).(More)
Critically ill patients are routinely exposed to high concentrations of supplemental oxygen for prolonged periods of time, which can be life-saving in the short term, but such exposure also causes severe lung injury and increases mortality. To address this therapeutic dilemma, we studied the mechanisms of the tissue-damaging effects of oxygen in mice. We(More)
To determine the role of cyclooxygenase (COX)-2 in anthracycline-induced cardiac toxicity, we administered doxorubicin (Dox) to mice with genetic disruption of COX-2 (COX-2-/-). After treatment with Dox, COX-2-/- mice had increased cardiac dysfunction and cardiac cell apoptosis compared with Dox-treated wild-type mice. The expression of the death-associated(More)
BACKGROUND AND AIMS Inflammatory bowel diseases (IBDs) are heterogeneous disorders with complex aetiology. Quantitative genetic studies suggest that only a small proportion of the disease variance observed in IBD is accounted for by genetic variation, indicating a potential role for differential epigenetic regulation in disease aetiology. The aim of this(More)
