Astrovirus-induced “white chicks” condition – field observation, virus detection and preliminary characterization

SummaryA method is described for the extraction with buffers of near physiological pH of a plasminogen activator from porcine salivary glands. Substantial purification of the activator was achieved although this was to some extent complicated by concomitant extraction of nucleic acid from the glands. Preliminary characterization experiments using specific inhibitors suggested that the activator functioned by a similar mechanism to that proposed for urokinase, but with some important kinetic differences in two-stage assay systems. The lack of reactivity of the pig gland enzyme in these systems might be related to the tendency to protein-protein interactions observed with this material.

SummaryA preliminary characterization of a fibrinolytic inhibitor released by human umbilical vein endothelial cells in primary culture is reported. This molecule of Mr comprised between 2 × 105 and 106 and of μ2 mobility precipitates at 43% ammonium sulphate saturation and is totally adsorbed on Concanavalin A Sepharose 4 B. A possible relationship with a macroglobulins is discussed.

Night tourism development comes up as an innovative strategy for tourism development in this current intense competition. There are four main elements in night tourism, namely economic, social, environmental, and night atmosphere. Berastagi is the most popular tourist destination in Karo Regency, Sumatera Utara, Indonesia, which already have night tourism destination but unfortunately undeveloped yet. Night tourism development in Berastagi must be with the local wisdom approach to maximize its benefit. Karonese as the majority ethnic of the local community in this area potential to be developed on its night tourism. This paper only analyzes the environmental and night atmosphere aspects in Berastagi’s night tourism, which based on local wisdom. Qualitative primary data from field observation and depth interview results have been analyzed by using the descriptive method. The study shows that involving local wisdom in developing the environment and night atmosphere can give the typical identity for the night tourism in Berastagi.Night Tourism
