Understanding patterns of connectivity among populations of marine organisms is essential for the development of realistic, spatially explicit models of population dynamics. Two approaches, empirical genetic patterns and oceanographic dispersal modelling, have been used to estimate levels of evolutionary connectivity among marine populations but rarely have(More)
Social protection against the cost of illness is a central policy objective of Universal Health Coverage and the post-2015 Global strategy for Tuberculosis (TB). Understanding the economic burden associated with TB illness and care is key to identifying appropriate interventions towards achieving this target. The aims of this study were to identify points(More)
1. Long-lived sedentary organisms with a massive morphology are often assumed to utilize a storage effect whereby the persistence of a small group of adults can maintain the population when sexual recruitment fails. However, employing storage effects could prove catastrophic if, under changing climatic conditions, the time period between favourable(More)
The patch dynamics (colonisation rate, growth rate, and extinction rate) are quantified for two dominant species of macroalgae on a Caribbean forereef in Belize: Lobophora variegata (Lamouroux) and Dictyota pulchella (Hörnig and Schnetter). Measurements were taken on time scales of days, weeks, months, and years during which three hurricanes occurred. All(More)
A proportion of cytogenetic abnormalities in myelodysplastic syndromes (MDS) and acute myeloid leukaemia (AML) may escape detection by high-resolution genomic technologies, but can be identified by conventional cytogenetic and molecular analysis. Here, we report the detection of a reciprocal translocation t(7;21)(p22;q22) in the marrow of two adults with(More)
Symbiodinium D, a relatively rare clade of algal endosymbiont with a global distribution, has attracted interest as some of its sub-cladal types induce increased thermal tolerance and associated trade-offs, including reduced growth rate in its coral hosts. Members of Symbiodinium D are increasingly reported to comprise low-abundance ‘cryptic’ (<10 %)(More)
An avirulent, streptomycin-dependent (Str-D) mutant ofStreptococcus suis type 1/2 was produced and characterized by its antimicrobial susceptibility, growth kinetics, biochemical reactions and reversion rate. Homologous and heterologous vaccine trials in mice resulted in complete protection against challenge withS. suis types 1 and 1/2 and partial(More)

Global guidelines for new technologies are based on cost and efficacy data from a limited number of trial locations. Country-level decision makers need to consider whether cost-effectiveness analysis used to inform global guidelines are sufficient for their situation or whether to use models that adjust cost-effectiveness results taking into account(More)
Organisms exposed to environmental stressors respond by rapidly synthesising a suite of highly conserved proteins called heat shock proteins (HSPs). Environmental stress can also enhance and/or block memory formation, with long-term memory formation requiring gene activation and protein synthesis. Thermal stress in the pond snail Lymnaea stagnalis can(More)
