    Abstract The cDNA sequences encoding the adult alpha- and beta-globin polypeptides of a marsupial, the native cat Dasyurus viverrinus, have been cloned and their nucleotide sequences have been determined. Using these cDNA clones we have determined the chromosomal locati...

    Investigations on self-assembling/induced-disassembling systems have led to the design of molecular-level devices capable of performing a variety of functions. Some of the work carried out in this field is illustrated.

    <jats:p>The wing polyphenism of pea aphids is a compelling laboratory model with which to study the molecular mechanisms underlying phenotypic plasticity. In this polyphenism, environmental stressors such as high aphid density cause asexual, viviparous adult female aphi...

    <jats:p>Cooperation can be sustained by institutions that punish free-riders. Such institutions, however, tend to be subverted by corruption if they are not closely watched. Monitoring can uphold the enforcement of binding agreements ensuring cooperation, but this usual...

    Recombination of evolutionarily unrelated domains is a mechanism often used by evolution to produce variety in soluble proteins. By using a classification of polytopic transmembrane domains into families, we examined integral membrane proteins for evidence of this mecha...

    Transduction with replication-incompetent recombinant adenovirus (Ad) vectors results in a rapid activation of innate immune responses, such as inflammatory cytokine production and subsequent tissue damage. The precise mechanisms of the innate immune responses induced b...

    Abstract The nickel tetrahedral sulfur-coordinated core formed upon metal replacement of the native iron in Desulfovibrio sp. rubredoxins is shown to mimic the reactivity pattern of nickel-containing hydrogenases with respect to hydrogen production, deuterium-proton exc...

    The high-density lipoprotein-associated enzyme paraoxonase 1 (PON1) hydrolyzes lactones, aromatic esters, and neurotoxic organophosphorus (OP) compounds, including insecticide metabolites and nerve agents. Experiments with mice lacking PON1 (PON1−/− mice) have establish...

    Abstract We have established an efficient transposontagging system in Arabidopsis thaliana using the Activator/Dissociation (Ac/Ds) elements from maize. This system consists of two components, a stable trans-activator, Acst, that supplies transposase, and a cis-responsi...

    Infectious tolerance describes the process of CD4(+) regulatory T cells (Tregs) converting naïve T cells to become additional Tregs. We show that antigen-specific Tregs induce, within skin grafts and dendritic cells, the expression of enzymes that consume at least 5 dif...
