No vaccine to protect against an estimated 238,000 shigellosis deaths per year is widely available.S.sonnei is the most prevalent Shigella, and multiple serotypes of S.flexneri, which change regionally and globally, also cause significant disease.The leading Shigella vaccine strategies are based on the delivery of serotype specific O-antigens.A str
One species, two developmental modes: a case of geographic poecilogony in marine gastropods
Abstract Background Poecilogony, the presence of two developmental modes in the same animal species, is a rare phenomenon.Few cases of poecilogony have been suggested for marine invertebrates including molluscs and even less stood extensive testing, mostly revealing a species pair with differing developmental modes.We studied a textbook example of
Interacting Temperature, Nutrients and Zooplankton Grazing Control Phytoplankton Size-Abundance Relationships in Eight Swiss Lakes
Biomass distribution among size classes follows a power law where the Log-abundance of taxa scales to Log-size with a slope that responds to environmental abiotic and biotic conditions.The interactions between ecological mechanisms controlling the slope of locally realized size-abundance relationships (SAR) are however not well understood.Here we t
A systematic review of prediction models for spontaneous preterm birth in singleton asymptomatic pregnant women with risk factors
Backgrounds: Spontaneous preterm birth (SPB) is a global problem.Early screening, identification, and prevention in asymptomatic pregnant women with risk factors for preterm birth Powder Bronzers can help reduce the incidence and mortality of preterm births.Therefore, this study systematically reviewed prediction models for spontaneous preterm birt
