Inflammatory bowel diseases (IBD), Crohn's disease (CD) and ulcerative colitis (UC), were retrospectively assessed on the incidence and prevalence in Vukovarsko-Srijemska County, continental Croatia. There were a total number of 150 patients, 119 with UC and 31 with CD. Of them, 79.3% were patients with UC, indicating a predominant participation of UC in the sample. Comparisons between the peri...

Upconverted circularly polarized luminescence (UC-CPL) is coined by combining two individual concepts of photon upconversion (UC) and (CPL). It has exhibited great performance potential applications in various fields, arousing enormous attention from scientists. The emergence, amplification modulation UC-CPL can be adjusted through regulation the UC process assembled state emitters. Benefitting...

background : many studies have investigated the effects of psychological factors on disease activity in patients with ulcerative colitis (uc). however, the number of studies that have assessed the correlation between immunologic markers of uc and psychological distress are few. therefore, we designed a study to determine the association between two immuno-biological markers, peripheral/central ...

Ulcerative colitis (UC) is a chronic relapsing inflammatory bowel disease, yet its etiology and pathogenesis remain poorly understood. The aberrant expression of T lymphocytes plays an essential role in the progression of UC. This study aimed to evaluate the expression profile of circulating Th17, Th1 and Tc1 cells in patients with active and inactive UC. Our results revealed that the percentag...

BACKGROUND Although the etiology of idiopathic ulcerative colitis (UC) remains poorly understood, the intestinal flora is suspected to play an important role. Specific, consistent abnormalities in flora composition peculiar to UC have not yet been described, however Clostridium difficile colitis has been cured by the infusion of human fecal flora into the colon. This approach may also be applic...

BACKGROUND AND AIMS Although some ulcerative colitis (UC) patients are diagnosed when they do not have any UC-related symptoms, clinical features and prognosis of UC diagnosed in asymptomatic patients remain unclear. METHODS Data for UC patients who were asymptomatic at diagnosis were retrospectively reviewed from the IBD database of the Asan Medical Center. The clinical characteristics and p...

BACKGROUND Previous studies suggest a link between gut microbiota and the development of ulcerative colitis (UC) and irritable bowel syndrome (IBS). Our aim was to investigate any quantitative differences in faecal bacterial compositions in UC and IBS patients compared to healthy controls, and to identify individual bacterial species that contribute to these differences. METHODS Faecal microb...

BACKGROUND Irritable bowel syndrome (IBS) is more common in patients with ulcerative colitis (UC) than expected. The prevalence of IBS in patients with UC with longstanding disease is not known. We investigated the prevalence of IBS-like symptoms in patients with UC in remission and longstanding disease in comparison to control subjects. METHODS Sixty-eight patients with UC and 33 patients wi...

BACKGROUND Intestinal fibrosis is a process driven by chronic inflammation leading to increased presence of myofibroblasts and collagen deposition. Although strictures are rarely seen in ulcerative colitis [UC], longstanding disease is believed to cause fibrosis resulting in altered bowel function. METHODS The presence of fibrosis was studied in colectomy specimens from patients with recent-o...
