    Notes: . The expression of cysteine proteinases by metacyclic promastigotes of Leishmania mexicana was investigated using gelatin polyacrylamide gel electrophoresis. Two prominent bands were detected which distinguished metacyclics from multiplicative promastigotes, lacking detectable cysteine proteinase activity, and amastigotes, with a distinct banding pattern composed of multiple enzymes. A correlation between relative activity of the metacyclic-specific bands and the prevalence of metacyclics was found both during the growth cycle in vitro as metacyclogenesis occurred, and by comparison of stationary phase populations from consecutive subpassages in vitro. Irreversible inhibition of the metacyclic activities using N-benzyloxycarbonyl-phenylalanyl-alanyl diazomethane did not inhibit metacyclic to amastigote transformation in vitro. These activities provide a useful biochemical marker for the metacyclic promastigotes of L. mexicana.

    Notes: . The products and pathways of glucose catabolism in the insect trypanosomatids Herpetomonas muscarum ingenoplastis and Herpetomonas muscarum muscarum have been studied with the aim of elucidating how both organisms are able to proliferate well under aerobic and anaerobic conditions. When incubated in medium containing glucose as the only exogenous carbon source, catabolism was found to be fermentative in both cases. Acetate was a major product of both organisms while H. m. ingenoplastis produced more ethanol and propionate and less succinate than H. m. muscarum. Ethanol production by H. m. ingenoplastis decreased both under anaerobic conditions and in the presence of elevated CO2 concentrations, whereas succinate and propionate release by this organism were greater in high CO2 and anoxia, respectively. Succinate production by H. m. muscarum was greatest under anaerobic conditions in elevated CO2 whereas propionate was only a minor product. The same four products were released during growth of the organisms in complex medium, but the relative proportions differed suggesting that other substrates were being used. Both organisms contained enzymes of the glycolytic and pentose phosphate pathways, but while all activities of the TCA cycle were present in H. m. muscarum. NAD-linked isocitrate dehydrogenase, α-ketoglutarate dehydrogenase, succinate CoA synthase and succinate dehydrogenase were not detected in H. m. ingenoplastis. Fumarate reductase activity was present in both organisms. The data presented suggest that CO2-fixation and reverse flux through the TCA cycle may be important factors that enable the organisms to undergo anaerobiosis.

    Notes: Tackling health inequalities is moving up the policy agenda of richer societies like the UK, with governments looking for evidence to guide policy review and development. Observational studies of how childhood disadvantage compromises health in adulthood are an important part of the evidence base, but are largely inaccessible to the policy community. We develop a framework which captures the findings of these studies. Our framework highlights how disadvantage in childhood adversely affects both socio-economic circumstances and health in adulthood through a set of interlocking processes. Key among these are children's developmental health (their physical, cognitive and emotional development) and health behaviours, together with the associated educational and social trajectories. In breaking down the link between childhood disadvantage and adult health into its constituent elements, the framework provides a basis for understanding where and how policies can make a difference. The paper argues that the process of policy review and development needs to include both new programmes and the mainstream policies in which they are embedded.

    Notes: Using a multiple layer optical waveguide system consisting of two vertically slab waveguides, classical Young's fringes may be obtained in the far-field diffraction plane. In agreement with the simple theory of diffraction interference the spacing of the far-field fringes is easily observed on mm to cm dimensions without further transformation of the output light. The simple methods of fabrication and means of optical coupling should provide a readily adaptable method for examining the principles of interferometry in an integrated optical format. The structure acts to transform polarized incident plane wave input light into separate slab modes of the device which emerge as two closely spaced and coherent sources at the output. The elements required for a classical Young's fringe demonstration are therefore all embodied in this approach. The basic concept can be applied to an optical method for sensing. In one example of this we demonstrate measurement of the phase difference induced between the upper and lower propagating modes in structures due to water vapor diffusion into the layers which are formed from hydrophilic polymers. The Young's fringe patterns exhibit a spatial intensity distribution which is sensitive to water vapor introduced over the surface of the structure. Differences in the effective index between the modes of the two waveguides during the diffusion of the vapor causes phase shifts which result in redistribution in the fringe pattern. The anticipated limit of detection of these devices is lower than 1 ppm for water vapor. © 1999 American Institute of Physics.
