Smoking and inflammatory bowel disease: comparison with lupus erythematiosus. A case-control study

Smoking is rare in patients with ulcerative colitis (UC). Onsets are common after stopping smoking. Several observations suggest possible immunologic mechanisms in UC. As smoking has an immunosuppressive effect, a possible role of smoking in UC could be immunosuppression. In this study an analogous hypothesis was investigated by studying smoking habits in patients with systemic lupus erythematosus

Smoking habits in patients with inflammatory bowel disease. A case control study.

In a case-control study there were significantly fewer smokers among patients with ulcerative colitis both at disease onset and at interview, the relative risk compared with non-smokers being 0.33 and 0.12, respectively. Among female patients with Crohn's disease there were significantly more smokers, the relative risk being 2.70 and 2.33, respectively. Of the ex-smokers with ulcerative colitis, t

Smoking habits in patients with inflammatory bowel disease

The proportion of smokers in this study was significantly lower among patients with ulcerative colitis (13%) than among patients with Crohn's disease (47%), the difference being significant for both sexes and for the age groups both below and above 40 years. The proportion of male ex-smokers among patients with ulcerative colitis (28%) was higher than among patients with Crohn's disease (8%), wher

Hydrolysis of phosphatidylethanolamine by human pancreatic phospholipase A2. Effect of bile salts.

The 2-ester bond of 14C-2-arachidonyl phosphatidylethanolamine (PE) was hydrolyzed faster than that of 3H-2-arachidonyl phosphatidylcholine (PC) by human pancreatic phospholipase A2 (PLA2) with mixed PE-PC (1:9 w/w) liposomes of pure sonicated PE or PC as substrate. The PC portion of the mixed PE-PC liposomes was more readily attacked by PLA2 than the PC of pure PC liposomes. At different bile sal

Systematiskt säkerhetsarbete och beslutsfattande : - att förstå, förklara och förbättra

Sekuritet eller den säkerhet i samma betydelse som engelskans security, handlar om det verksamhetsskydd för organisation, medarbetare och övriga som behövs för att motverka fara, skada, förlust eller brott. Sekuritet är därmed en fråga om trygghet. För att möta framtidens utmaningar har doktorandarbetet syftat till att studera och identifiera effektiva processer gällande sekuritetshantering och be

Linking damping of electromechanical oscillations to system operating conditions using neural networks

This paper presents the application of Neural Networks to link the damping of electromechanical oscillations in the Nordic power system to the measured operating conditions. Different neural network topologies have already been presented in the literature for this application, but using exclusively data from simulations. The primary objective of the paper is to analyze how these topologies behave
