Purpose The purpose of this study was to clarify the factors that influence the incidence of colorectal neoplasia in patients with type 2 diabetes mellitus (DM). Study Design and Setting Among a total of 1176 patients who underwent total colonoscopy at our hospital, we retrospectively analyzed 168 patients with type 2 DM. Univariate and multivariate logistic regression analyses were then perf...
From January 1985 to January 1990, measurements of acid alpha-D-glucosidase activity in amniocytes or chorionic villus samplings were done for 24 pregnant mothers who were carriers of Pompe's disease. 6 women had two subsequent pregnancies. Amniotic fluid was obtained by transabdominal amniocentesis performed on 10 of them, while chorionic villus samplings were obtained in the other 20. The res...
We are investigating the molecular mechanisms involved in the localization of lysosomal enzymes in Dictyostelium discoideum, an organism that lacks any detectable mannose-6-phosphate receptors. The lysosomal enzymes alpha-mannosidase and beta-glucosidase are both initially synthesized as precursor polypeptides that are proteolytically processed to mature forms and deposited in lysosomes. Time c...
Starch digestion involves the breakdown by α-amylase to small linear and branched malto-oligosaccharides, which are in turn hydrolyzed to glucose by the mucosal α-glucosidases, maltase-glucoamylase (MGAM) and sucrase-isomaltase (SI). MGAM and SI are anchored to the small intestinal brush-border epithelial cells, and each contains a catalytic N- and C-terminal subunit. All four subunits have α-1...
1. The behaviour of rat liver alpha-glucosidases on dextran gel (Sephadex G-100) columns was studied. A ;retardation' of an acid alpha-glucosidase activity was observed. This activity was identified as lysosome alpha-(1-->4)-glucosidase. A single gel-filtration step resulted in a 700-fold purification of the enzyme. The same technique was also used to purify the acid alpha-glucosidase of human ...
1. The pH-activity relationship of invertase has been studied in vivo and in vitro under identical external environmental conditions. 2. The effect of changing (H(+)) upon the sucroclastic activity of living cells of S. cerevisiae and of invertase solutions obtained therefrom has been found, within experimental error, to be identical. 3. The region of living yeast cells in which invertase exert...
