LOW GENETIC AND PHENOTYPIC DIVERGENCE IN A CONTACT ZONE BETWEEN FRESHWATER AND MARINE STICKLEBACKS: GENE FLOW CONSTRAINS ADAPTATION

Low genetic and phenotypic divergence in a contact zone between freshwater and marine sticklebacks: gene flow constrains adaptation

Abstract Background Distinct hybrid zones and phenotypic and genomic divergence is often observed between marine and freshwater threespine sticklebacks (Gasterosteus aculeatus).Nevertheless, cases also exist where marine-freshwater divergence is diffuse despite seemingly similar environmental settings.In order to assess what characterizes these hig

An in vitro-identified high-affinity nucleosome-positioning signal is capable of transiently positioning a nucleosome in vivo

Abstract Background The physiological function of eukaryotic DNA occurs in the context of nucleosomal arrays that can expose or obscure defined segments of the genome.Certain DNA sequences are capable of strongly positioning a nucleosome in vitro, suggesting the possibility that favorable intrinsic signals might reproducibly structure chromatin seg

Visual evoked potentials waveform analysis to measure intracortical damage in a preclinical model of multiple sclerosis

IntroductionVisual evoked potentials (VEPs) are a non-invasive technique Plunger Cutters routinely used in clinical and preclinical practice.Discussion about inclusion of VEPs in McDonald criteria, used for Multiple Sclerosis (MS) diagnosis, increased the importance of VEP in MS preclinical models.While the interpretation of the N1 peak is recogniz
