Generalized dissimilarity modelling (GDM) is a statistical technique for analysing and predicting spatial patterns of turnover in community composition (beta diversity) across large regions. The approach is an extension of matrix regression, designed specifically to accommodate two types of nonlinearity commonly encountered in large-scaled ecological data(More)
Regional conservation planning can often make more effective use of sparse biological data by linking these data to remotely mapped environmental variables through statistical modelling. While modelling distributions of individual species is the best known and most widely used approach to such modelling, there are many situations in which more information(More)
This study was undertaken to evaluate the safety and therapeutic efficacy of the prostaglandin E1 analogue, misoprostol, when compared with ranitidine in the healing of duodenal ulcers. Sixty patients with endoscopically proven duodenal ulcers participated in a double-blind controlled randomised trial comparing misoprostol 400 microgram and ranitidine 150(More)
Forty patients with duodenal ulcer, considered healed at endoscopy, were entered in a double-blind trial and treated for up to one year with sucralfate, 500 mg before breakfast, lunch, supper and 1000 mg on retiring, or with placebo. The subjects were interviewed and endoscopy was performed at 0, 3, 6, 9 and 12 months or at any time if pain recurred and(More)
Antral mucosal biopsy specimens were examined microbiologically and histologically for the presence of Campylobacter pylori in 224 patients with upper gastrointestinal symptoms. The gastric mucosa of 183 patients (82%) were found to harbour C. pylori. C. pylori was strongly associated with the presence of histological gastritis (93%) and was detected in(More)

Sixty patients with endoscopically proven healed duodenal ulcers were treated for a year with either pirenzepine (Gastrozepin; Boehringer Ingelheim) 100 mg daily, cimetidine 400 mg at night, or placebo, The monthly relapse rate (patients per month) in the first 3 months (pirenzepine 2,3, cimetidine 2,3, placebo 3,0) and in the next 9 months (pirenzepine(More)
This article seeks to create an awareness of the manner in which our society in general, albeit unconsciously, negatively influences the disease by an erroneous and unnecessarily pessimistic attitude to cancer. It is a plea for a change in our irrational beliefs about cancer, which form a striking analogy to the phenomenon of the tribal aboriginal's custom(More)
Quantifying survey completeness is a key step in designing and interpreting biodiversity assessments. To date this has only been examined either at a local scale through repetitive sampling, or across broader geographic areas through multiple survey sites. In this paper, we determine the completeness of sampling at both local and continental scales, of the(More)
