Abstract

This paper provides exact power contours to guide the planning of reliability studies, where the parameter of interest is the coefficient of intraclass correlation rho derived from a one-way analysis of variance model. The contours display the required numbers of subjects k and number of repeated measurements n that provide 80 per cent power for testing Ho: rho less than or equal to rho 0 versus H1: rho greater than rho 0 at the 5 per cent level of significance for selected values of rho o. We discuss the design considerations of these results.

Molecular heterochrony and the evolution of sociality in bumblebees (Bombus terrestris).

Sibling care is a hallmark of social insects, but its evolution remains challenging to explain at the molecular level. The hypothesis that sibling care evolved from ancestral maternal care in primitively eusocial insects has been elaborated to involve heterochronic changes in gene expression. This elaboration leads to the prediction that workers in these species will show patterns of gene expression more similar to foundress queens, who express maternal care behaviour, than to established queens engaged solely in reproductive behaviour. We tested this idea in bumblebees (Bombus terrestris) using a microarray platform with approximately 4500 genes. Unlike the wasp Polistes metricus, in which support for the above prediction has been obtained, we found that patterns of brain gene expression in foundress and queen bumblebees were more similar to each other than to workers. Comparisons of differentially expressed genes derived from this study and gene lists from microarray studies in Polistes and the honeybee Apis mellifera yielded a shared set of genes involved in the regulation of related social behaviours across independent eusocial lineages. Together, these results suggest that multiple independent evolutions of eusociality in the insects might have involved different evolutionary routes, but nevertheless involved some similarities at the molecular level.

Population structure and properties of Candida albicans, as determined by multilocus sequence typing.

We submitted a panel of 416 isolates of Candida albicans from separate sources to multilocus sequence typing (MLST). The data generated determined a population structure in which four major clades of closely related isolates were delineated, together with eight minor clades comprising five or more isolates. By Fisher's exact test, a statistically significant association was found between particular clades and the anatomical source, geographical source, ABC genotype, decade of isolation, and homozygosity versus heterozygosity at the mating type-like locus (MTL) of the isolates in the clade. However, these associations may have been influenced by confounding variables, since in a univariate analysis of variance, only the clade associations with ABC type and anatomical source emerged as statistically significant, providing the first indication of possible differences between C. albicans strain type clades and their propensity to infect or colonize different anatomical locations. There were no significant differences between clades with respect to distributions of isolates resistant to fluconazole, itraconazole, or flucytosine. However, the majority of flucytosine-resistant isolates belonged to clade 1, and these isolates, but not flucytosine-resistant isolates in other clades, bore a unique mutation in the FUR1 gene that probably accounts for their resistance. A significantly higher proportion of isolates resistant to fluconazole, itraconazole, and flucytosine were homozygous at the MTL, suggesting that antifungal pressure may trigger a common mechanism that leads both to resistance and to MTL homozygosity. The utility of MLST for determining clade assignments of clinical isolates will form the basis for strain selection for future research into C. albicans virulence.

Thymopoietin, a thymic polypeptide, prevents nicotinic agonist-induced morphological changes in neonatal muscle cells in culture.

Thymopoietin, a polypeptide hormone isolated from thymus and involved in immune function, potently inhibited [125I]alpha-bungarotoxin binding to neonatal muscle cells in culture (IC50 = 3.8 nM) and blocked carbachol-stimulated 22Na uptake with an IC50 of 1.9 +/- 0.2 nM and 23 +/- 7 nM at a half-maximal and maximal concentration of carbachol, respectively. Studies were subsequently done to evaluate potential long-term functional consequences of this interaction of thymopoietin at the nicotinic receptor. Exposure (1-3 days) of neonatal muscle cells in culture to nicotine (3 x 10(-6) M) or carbachol (1 x 10(-6) M) resulted in a decline in myotube branching and a decrease in myotube length. Thymopoietin did not appreciably alter myotube morphology on its own; however, it prevented the effects of nicotine and carbachol on muscle cell morphology at concentrations (1-10 nM) which corresponded well to those with which thymopoietin interacted at the receptor. The action of alpha-bungarotoxin on the myotubes was very similar to that of thymopoietin. These studies suggest that the endogenously occurring polypeptide, thymopoietin, has the potential to modulate muscle cell morphology through an interaction at the nicotinic receptor.
