The chamois, distributed over most of the medium to high altitude mountain ranges of southern Eurasia, provides an excellent model for exploring the effects of historical and evolutionary events on diversification. Populations have been grouped into two species, Rupicapra pyrenaica from southwestern Europe and R. rupicapra from eastern Europe. However, a(More)
Gene flow was examined among Anopheles albimanus populations from Cuba, Mexico, Guatemala, El Salvador, Nicaragua, Costa Rica, Panama, Colombia, and Venezuela by examining variation at four microsatellite (MS) loci and a mitochondrial DNA (mtDNA) marker. There was little variation among Central American populations and weak isolation by distance was only(More)
A framework for learning optimal dictionaries for simultaneous sparse signal representation and robust class classification is introduced in this paper. This problem for dictionary learning is solved by a class-dependent supervised simultaneous orthogonal matching pursuit , which learns the intra-class structure while increasing the inter-class(More)
Loss of sexual reproduction is considered an evolutionary dead end for metazoans, but bdelloid rotifers challenge this view as they appear to have persisted asexually for millions of years. Neither male sex organs nor meiosis have ever been observed in these microscopic animals: oocytes are formed through mitotic divisions, with no reduction of chromosome(More)
Coxsackieviruses are important human pathogens, frequently causing myocarditis, pancreatitis, and a variety of less severe diseases. B lymphocytes appear central to the interaction between these viruses and their mammalian hosts, because agammaglobulinemic humans, genetically incapable of antibody production, are susceptible to chronic infections by(More)
We demonstrated that peripheral T cell tolerance toward murine melanoma self-antigens gp100 and TRP-2 can be broken by an autologous oral DNA vaccine containing the murine ubiquitin gene fused to minigenes encoding peptide epitopes gp100(25-33) and TRP-2(181-188). These epitopes contain dominant anchor residues for MHC class I antigen alleles H-2D(b) and(More)
Although many viruses have been isolated from patients with multiple sclerosis (MS), as yet, no one agent has been demonstrated to cause MS. In contrast, epidemiological data indicate that viral infections are associated with exacerbations of MS. Here, we present data showing that virus infections can subclinically prime animals for central nervous system(More)
African swine fever virus (ASFV), the causative agent of one of the most devastating swine diseases, has been considered exclusively cytoplasmic, even though some authors have shown evidence of an early stage of nuclear replication. In the present study, an increment of lamin A/C phosphorylation was observed in ASFV-infected cells as early as 4 h(More)
DNA immunization works, as has been amply demonstrated in a variety of microbial and tumor models. However, the mechanisms which underpin its success remain unclear. Using intramuscular delivery of DNA, we wish to precisely define how DNA-encoded antigens induce CD8+ T-cells (most cytotoxic T-cells; CTL), CD4+ T-cells (mostly helper cells) and antibodies;(More)
Previous studies have investigated the influence of neuroscience information or images on ratings of scientific evidence quality but have yielded mixed results. We examined the influence of neuroscience information on evaluations of flawed scientific studies after taking into account individual differences in scientific reasoning skills, thinking(More)
