Shiga toxin 2 overexpression in Escherichia coli O157:H7 strains associated with severe human disease
(Elsevier, 2011-12)
Variation in disease severity among Escherichia coli O157:H7 infections may result from differential expression of Shiga toxin 2 (Stx2). Eleven strains belonging to four prominent phylogenetic clades, including clade 8 ...
Modulating the fundamental inductive-capacitive resonance in asymmetric double-split ring terahertz metamaterials
(AIP Publishing, 2011-03-24)
We investigate resonant transmission of planar asymmetric metamaterials made from double split-ring resonators. As the symmetry of the unit cell resonator is broken by displacing the two gaps away from the center in opposite ...
Smooth components of Springer fibers
(Association des Annales de l'Institut Fourier, 2011)
This article studies components of Springer fibers for gl(n) that are associated to closed orbits of GL(p) X GL(q) on the flag variety of GL(n), n = p + q. These components occur in any Springer fiber. In contrast to the ...
Predator-induced changes of female mating preferences: Innate and experiential effects
(BioMed Central, 2011-07-04)
Background: In many species males face a higher predation risk than females because males display elaborate traits that evolved under sexual selection, which may attract not only females but also predators. Females are, ...
Functional genomics of the horn fly, Haematobia irritans (Linnaeus, 1758)
(BioMed Central, 2011-02-10)
Background: The horn fly, Haematobia irritans (Linnaeus, 1758) (Diptera: Muscidae) is one of the most important ectoparasites of pastured cattle. Horn flies infestations reduce cattle weight gain and milk production. ...
Importance of the long-chain fatty acid beta-hydroxylating cytochrome P450 enzyme YbdT for lipopeptide biosynthesis in Bacillus subtilis strain OKB105
(MDPI, 2011-03-08)
Bacillus species produce extracellular, surface-active lipopeptides such as surfactin that have wide applications in industry and medicine. The steps involved in the synthesis of 3-hydroxyacyl-coenzyme A (CoA) substrates ...
Biomedically-focused research productivity by Namibian authors and institutions 1995-2010
(2011-06)
Publications are the result of individual scientists or 'webs' of collaborators who present their scientific observations and share them with the scientific community. A study of authors and institutions who have published ...
Mosquito ingestion of antibodies against mosquito midgut microbiota improves conversion of ookinetes to oocysts for Plasmodium falciparum, but not P. yoelii
(Elsevier BV, 2011-07-13)
The mosquito midgut is a site of complex interactions between the mosquito, the malaria parasite and the resident bacterial flora. In laboratory experiments, we observed significant enhancement of Plasmodium falciparum ...
Community Empowerment Consultation Model

Characterization of recombinant B. abortus strain RB51SOD toward understanding the uncorrelated innate and adaptive immune responses induced by RB51SOD compared to its parent vaccine strain RB51
(Frontiers Media, 2011-11-25)
Brucella abortus is a Gram-negative, facultative intracellular pathogen for several mammals, including humans. Live attenuated B. abortus strain RB51 is currently the official vaccine used against bovine brucellosis in the ...
