Clostridium thermocellum endoglucanase D (EC 3.2.1.4: EGD), which is encoded by the celD gene, was found to bind Ca2+ with an association constant of 2.03 x 10(6) M-1. Ca2+ stimulated the activity of EGD towards swollen Avicel by 2-fold. In the presence of Ca2+, the Kd of the enzyme towards p-nitrophenyl-beta-D-cellobioside and carboxymethylcellulose was(More)
This study investigated the use of the Porteus Maze test as a measure of reflection/impulsivity when used with both normal and retarded subjects. Study 1 (N = 90) provided sample data for three equal groups of 30 adolescent students in the regular school. These were defined as above average, average, and below average in general intelligence. In addition to(More)
The blood levels of alpha 2-macroglobulin, alpha 1-antitrypsin, CT inactivator, antithrombin III and alpha 2-antiplasmin were measured in 18 primigravidae with moderate or severe pre-eclampsia and in 18 gestation-matched primigravidae with uncomplicated pregnancy. The mean levels of the proteinase inhibitors did not differ between the pre-eclampsia and(More)
The activity of urokinase and tissue activator on fibrin plates was inhibited by plasma from women in the third trimester of pregnancy to a greater extent than by non-pregnant plasma. Pregnancy also inhibited the amidolytic activity of urokinase. The high molecular weight fractions of pregnancy plasma gel filtered on Sephadex G-200 showed comparable(More)
Ingestion of 750 ml cider inhibited plasma fibrinolytic activity: unfermented apple juice appeared to have some inhibitory effect, but this did not reach statistical significance. Cider inhibited urokinase-induced clot lysis in a concentration-dependent manner; the inhibitory activity was heat-stable and non-dialysable. The fibrinolytic activities of(More)
Plasma fibrinolytic activity and plasma inhibitory activity against urokinase and tissue activator were measured in primigravidae with moderate or severe pre-eclampsia and in gestation-matched primigravidae with uncomplicated pregnancy. The mean levels of fibrinolytic activity and inhibitory activity against urokinase and tissue activator did not differ(More)
This study investigated the feasibility of using measures of cognitive tempo with 66 institutionalized moderately-severely retarded adolescents and adults in the field settings of three Activity Centres--one rural and two urban. The Matching Familiar Figures Test and the Porteus Maze Tests could, with characteristic modifications, be administered to this(More)
This study investigated the effects of modification of conceptual tempo on the skilled performance of a group of mildly intellectually handicapped adolescents receiving training in a work preparation centre (N, 41). On the basis of performance on Kagan's Matching Familiar Figures Test the group was divided into two subgroups, reflective, impulsive and then(More)
