This study examined the intestinal antibody response in 26 healthy volunteers challenged with Cryptosporidium parvum oocysts. Fecal extracts were assayed for total secretory immunoglobulin A (IgA) and C. parvum-specific IgA reactivity. Specific IgA reactivity was standardized to IgA concentration and expressed as a reactivity index (RI). Anti-C. parvum fecal IgA (fIgA) increased significantly i...

Cells of an attenuated live vaccine strain (LVS) of F. tularensis grown under iron-restricted conditions were found to contain increased quantities of several proteins relative to cells of this same strain grown under iron-replete conditions. Mass spectrometric analysis identified two of these proteins as IglC and PdpB, both of which are encoded by genes located in a previously identified patho...

In the Preface, J. C. Taylor explains that while the book was initially intended as a loose proceedings for a seminar he organized in 1992, it evolved into something quite different. As a result, several of the papers in the book under review contain results and approaches which are more recent. In particular, three of the papers are related, to various degrees, to the monograph [?] that Taylor...

The basic helix-loop-helix (bHLH) transcription factors play important roles in a wide range of developmental processes in higher organisms. bHLH family members have been identified in a dozen of organisms including fruit fly, mouse and human. In this study, we identified 51 bHLH sequences in silico in the honey bee, Apis mellifera L. (Hymenoptera: Apidae), genome. Phylogenetic analyses reveale...

We show that the multiplier algebra of the Fourier algebra on a locally compact group G can be isometrically represented on a direct sum on non-commutative L spaces associated to the right von Neumann algebra of G. If these spaces are given their canonical Operator space structure, then we get a completely isometric representation of the completely bounded multiplier algebra. We make a careful ...

Across prehistoric Europe several techniques were used to produce salt, including solar evaporation and the briquetage method. Here, authors focus on a third technique in Romania western Ukraine. Building excavations at Băile Figa series of wooden troughs found there, conduct experiments elucidate how these objects may have been salt production: drip water onto rock surfaces break them up; or f...
