Fashion retailing – past, present and future

This issue of Textile Progress reviews the way that fashion retailing has developed as a result of the application of the World Wide Web and information and communications technology (ICT) by fashion-retail companies. The review therefore first considers how fashion retailing has evolved, analysing retail formats, global strategies, emerging and developing economies, and the factors that are threatening and driving growth in the fashion-retail market. The second part of the review considers the emergence of omni-channel retailing, analysing how retail has progressed and developed since the adoption of the Internet and how ICT initiatives such as mobile commerce (m-commerce), digital visualisation online, and in-store and self-service technologies have been proven to support the progression and expansion of fashion retailing. The paper concludes with recommendations on future research opportunities for gaining a better understanding of the impacts of ICT and omni-channel retailing, through which it may be possible to increase and develop knowledge and understanding of the way the sector is developing and provide fresh impetus to an already-innovative and competitive industr

Het beloop van het benigne ulcus ventriculi; resultaten van een follow-up-onderzoek

A follow-up investigation was conducted in 112 patients in whom a benign gastric ulcer had been found endoscopically between 1978 and 1984. Nine patients had been operated upon, mainly in the earlier years. Out of 65 patients ultimately selected for the study 38 underwent gastroscopy and 35 could be evaluated. Of these 21 (60%) had complaints and another 60% used intermittent or continuous medication because of complaints referred to the stomach. In 15 patients erosions (4) or benign gastric ulcers (11) were found. In all patients in whom it was looked for Campylobacter pylori was found in the gastric mucosa. The benign gastric ulcer is a chronic, recurrent affection. We did not find a large proportion of asymptomatic recurrent ulcers. Many patients continue to use drugs. The complaints in patients with mucosal lesions are often atypica

An appraisal of the role of biliary phospholipases in the pathogenesis of gallstone disease

Human bile contains proteins that influence nucleation of cholesterol. Recently, it has been suggested that activity of phospholipases in bile may play a role in this process. To study the influence of phospholipase on nucleation we have determined the effect of phospholipases A2, C and D on the nucleation time of model bile. Phospholipase C decreased the nucleation time, whereas phospholipase A2 inhibited nucleation. The phospholipases were effective only at relatively high concentrations. Phospholipase D was strongly inhibited in model bile and probably only influenced the nucleation time by an aspecific protein effect. The cleavage products of the different phospholipases were determined in native bile samples of 14 cholesterol gallstone patients, 6 patients without stones and 4 patients with pigment stones. In all samples, choline, phosphorylcholine and free fatty acids (FFA) could be detected. However, there was no significant difference between the three groups of patients. The rate of production of choline, phosphorylcholine and FFA was measured in bile incubated at 37 degrees C. Again, there was no significant difference between the three groups of patients. We conclude that phospholipase activity in bile does not play an important role in the pathogenesis of gallstone diseas

Cholesterol nucleation-influencing activity in T-tube bile

Nucleation-influencing activity was determined in T-tube bile samples derived from patients with obstructive jaundice. Since native T-tube bile samples do not nucleate, nucleation-influencing activity was determined by measuring the influence of T-tube bile on the nucleation time of model bile. In the assay, T-tube bile was mixed with model bile, and the nucleation time of this mixture was compared with the nucleation time of a model bile supplemented with the same amount of lipid as present in the bile sample. The results were expressed as ratio of the nucleation time of the mixture and the nucleation time of the control (NTm/NTc). There was a significant difference (p less than 0.01) between bile samples from patients with cholesterol gallstones and samples from patients with biliary obstruction due to other causes. More than 80% of the 33 samples from eight patients with stones were nucleation-promoting (NTm/NTc less than or equal to 0.6). Of the 40 bile samples from patients without stones, 7 were nucleation-promoting, 25 had no effect (NTm/NTc = 0.8 to 1.2) and 8 bile samples were nucleation-inhibiting (NTm/NTc greater than or equal to 1.4). There was no correlation between the lipid or protein content of a T-tube bile sample and its nucleation-influencing activity. The presence of both nucleation-promoting and nucleation-inhibiting activity in the same T-tube bile was demonstrated by chromatography on concanavalin A-Sepharose. More than 75% of the biliary protein did not bind to the column. This fraction showed nucleation-inhibiting activity.(ABSTRACT TRUNCATED AT 250 WORDS
