We analyzed short-term forces acting on the genetics of subdivided populations based on a temporal survey of the microsatellite variability in the hermaphrodite freshwater snail Bulinus truncatus. This species inhabits temporary habitats, has a short generation time and exhibits variable rates of selfing. We studied the variability over three sampling dates in 12 Sahelian populations (1161 indi...

Bilharzia is a public health problem in Cote dIvoire, especially rural areas. This study was conducted the locality of Guebo 2 located 45.2 kilometres from Abidjan, northwest Yopougon, with aim assessing epidemiological status bilharzia school environment where cases urinary had been reported 2012 prevalence 42.8%. 119 pupils were sampled schools A and B, Year 3, 4, 5 6 pupils. Urine stool samp...

Previously, we showed that neurons in the supraoculomotor area (SOA), known to encode vergence angle in normal monkeys, encode the horizontal eye misalignment in strabismic monkeys. The SOA receives afferent projections from the caudal fastigial nucleus (cFN) and the posterior interposed nucleus (PIN) in the cerebellum. The objectives of the present study were to investigate the potential roles...

The rootless duckweed Wolffia globosa can accumulate and tolerate relatively large amounts of arsenic (As); however, the underlying mechanisms were unknown. W. globosa was exposed to different concentrations of arsenate with or without l-buthionine sulphoximine (BSO), a specific inhibitor of γ-glutamylcysteine synthetase. Free thiol compounds and As(III)-thiol complexes were identified and quan...

Two new genera are established in the Dothideomycetes based on morphological and molecular data (SSU and LSU nuclear ribosomal sequences) to accommodate four ascomycete species collected from woody debris submerged in freshwater habitats. The genus Minutisphaera is represented by a single species, M. fimbriatispora, which was collected from freshwater habitats in temperate forests in North Amer...

The role of cerebellar circuits in the acquisition of new motor abilities is still a matter of intensive debate. To establish the contribution of posterior interpositus nucleus (PIN) to the performance and/or acquisition of reflex and classically conditioned responses (CRs) of the eyelid, the effects of microstimulation and/or pharmacological inhibition by muscimol of the nucleus were investiga...

Mountains are considered island-like systems often characterized by exceptional biodiversity and endemism. There many highly isolated mountain ranges in Africa that collectively have been called the Afromontane archipelago. Freshwater snails of genus Bulinus composed veterinary biomedical important species. These intermediate hosts for schistosomiasis parasites wide spread some species to be ad...
