Variable Adhesion Abilities and Overlapping Antigenic Properties in PlacentalPlasmodium falciparumIsolates

Variable adhesion abilities and overlapping antigenic properties in placental Plasmodium falciparum isolates.

BACKGROUND Pregnancy-associated malaria is characterized by selection and multiplication, in the placenta, of a distinct population of Plasmodium falciparum expressing particular variant surface antigens (VSAs) that adhere to chondroitin sulfate A (CSA). METHODS The adhesion of 40 freshly collected placental parasite isolates to bovine CSA and human placental low-sulfated chondroitin proteogl...

Contextual Variable Elimination with Overlapping Contexts

Belief networks (BNs) extracted from statistical relational learning formalisms often include variables with conditional probability distributions (CPDs) that exhibit a local structure (e.g, decision trees and noisy-or). In such cases, naively representing CPDs as tables and using a general purpose inference algorithm such as variable elimination (VE) results in redundant computation. Contextua...

Learning Causal Structure from Overlapping Variable Sets

Modern data-analysis methods are typically applicable to a single dataset. In particularly, they cannot integratively analyze datasets containing different, but overlapping, sets of variables. We show that by employing causal models instead of models based on the concept of association alone, it is possible to make additional interesting inferences by integrative analysis than by independent an...

Antigenic Properties of Hyaluronic Acid

1. Complement titrations, using 50% haemolysis as the end-point, were performed on forty guineapigs maintained on different levels of intake of vitamin C, and the results were evaluated statistically. 2. No significant change in complement was found to occur in guinea-pigs partially or completely deficient in vitamin C. 3. Addition of cabbage to the dietAdid not result in-any change in the comp...
