Studies were conducted during August and March–April in the Sargasso Sea south of Bermuda to examine rates of bacterial growth and picoplankton consumption by microbial consumers. Bacterial growth rates were estimated from [3H]thymidine (TdR) incorporation rates, while grazing rates were determined using fluorescently labeled prey (FLP). In addition, net bacterial growth rates were calculated f...

Dendritic cells (DC) are the most potent antigen-presenting cells for initiating immune responses. DC maturation can be induced by exposing of immature DC to pathogen products or pro-inflammatory factor, which dramatically enhances the ability of DC to activate Ag-specific T cells. In this study, a recombinant calreticulin fragment 39-272 (rCRT/39-272) covering the lectin-like N domain and part...

INTRODUCTION This study was conducted in a sugar belt region of western Kenya interfacing epidemic and endemic malaria transmission. We investigated Anopheles gambiae sensu stricto (ss) and Anopheles arabiensis species compositions and densities, human host choice, and infectivity. METHODOLOGY Mosquitoes were captured using pyrethrum spray catch technique and first identified based on morphol...

Statistical model validation is treated for a general class of nonparamet-ric uncertainty models. This problem is shown to reduce, in many cases of interest, to computing the limit of a sequence (V k) 1 1 of relative weighted volumes of convex sets in R k. An associated decision problem is shown to reduce to a pair of likelihood ratio tests. The notion of testability is introduced to describe u...
