BACKGROUND There is an increasing evidence, stemming from epidemiological studies as well as studies performed in human biopsies and animal and cell culture models, suggesting that folate is chemopreventive in colonic carcinogenesis. Hyperhomocysteinemia is frequently associated with folate deficiency. Homocysteine, an amino acid, is metabolized to(More)
BACKGROUND Nonsteroidal anti-inflammatory drugs (NSAIDs) inhibit colonic tumourigenesis and have an established usefulness in cancer prevention. Because polyamines are essential for neoplastic cell growth, the aim of this study was to evaluate the effect of NSAIDs (indomethacin, a nonselective COX-1 and COX-2 inhibitor) on polyamine metabolism in colon(More)
BACKGROUND Deoxycholic acid has long been attributed as a tumour promoter in the colon. It exerts its growth-related actions in a phorbol ester-like manner, by stimulating protein kinase C. The aim of this study was to investigate the effect of deoxycholic acid on proliferation and apoptosis in the colon, by exposing colon cancer cells to it in increasing(More)
BACKGROUND Alpha1-proteinase inhibitor (alpha1-PI), an anti-inflammatory protein thought to play a role in the intestinal inflammation, is synthesised by and released from the intestinal epithelial cells. IL-1beta is a key proinflammatory cytokine in the abnormal immune response that occurs in inflammatory bowel disease. Butyrate is a normal luminal(More)
The complement system plays an important role in the humoral immune response. Activation of the classical complement pathway is mediated by its subcomponent, C1q, which is involved in the pathogenesis of several autoimmune disorders. Among the main C1q-synthesising tissues, macrophages have been attributed as the main source. We investigated the effects of(More)
Polyamines arrive in the gut lumen mainly with food. Shortly after a meal, the majority of luminal polyamines disappear from the duodenal and jejunal lumen, by a mechanism of passive diffusion. The majority of luminal polyamines are degraded in the gut before reaching systemic circulation. Hence, there is broad evidence that luminal polyamines are indeed(More)
INTRODUCTION In the last two decades, an increase in obesity along with a number of co-morbidities has been recorded among children and adolescents. OBJECTIVE The aim was to investigate if there was a difference in nutritional status between adolescents who were active sportsmen and those who did not engage in sport activities other than regular physical(More)
BACKGROUND Amyloidosis represents a group of different diseases characterized by extracellular accumulation of pathologic fibrillar proteins in various tissues and organs. Severe amyloid deposition in the liver parenchyma has extrahepatic involvement predominantly in the kidney or heart. We evaluated the effect of ursodeoxycholic acid, in four patients with(More)
