Integration and Fixation Preferences of Human and Mouse Endogenous Retroviruses Uncovered with Functional Data Analysis
Endogenous retroviruses (ERVs), the remnants of retroviral infections in the germ line, occupy ~8% and ~10% of the human and mouse genomes, respectively, and affect their structure, evolution, and function. Yet we still ...
Reproductive biology and behavior of Doru taeniatum (Forficulidae)
(Revista de BioIogía Tropical 36(2B): 437-440, 1988., 1988)
This study deals with the biology of Doru taeniatum, (Forficuüdae), particulary the habitat, feeding, reproduction, maternal care, and nymphal stages. The density of adults is higher in the older corn plants. The earwings ...
Genetic diversity in Oryza glumaepatula wild rice populations in Costa Rica and possible gene flow from O. sativa
Wild crop relatives are an important source of genetic diversity for crop improvement. Diversity estimates are generally lacking for many wild crop relatives. The objective of the present study was to analyze how genetic ...
Genetic contributions to circadian activity rhythm and sleep pattern phenotypes in pedigrees segregating for severe bipolar disorder
Abnormalities in sleep and circadian rhythms are central features of bipolar disorder (BP), often persisting between episodes. We report here, to our knowledge, the first systematic analysis of circadian rhythm activity ...
Cellulose-Enriched Microbial Communities from Leaf-Cutter Ant (Atta colombica) Refuse Dumps Vary in Taxonomic Composition and Degradation Ability
Deconstruction of the cellulose in plant cell walls is critical for carbon flow through ecosystems and for the production of sustainable cellulosic biofuels. Our understanding of cellulose deconstruction is largely limited ...
Hallazgos fenotípicos por imágenes con Tomografía Dental Volumétrica (TDV) en amelogénesis imperfecta
Use of Dental Volumetric Tomography for Dental Phenotyping In Amelogenesis Imperfecta
Amelogénesis imperfecta (AI) se describe como un conjunto de defectos mendelianos en la biomineralización del esmalte dental, los cuales son severos en la mayoría de los casos al presentar anormalidades tales como un grosor ...
Methodology: The data are 29 sediment samples and these were collected (September 2006) each 200m in a parallel transect on the low spring tide level in a sandy beach of the Caribbean coast of Costa Rica. The data are ...
Reverse Transcription Errors and RNA-DNA Differences at Short Tandem Repeats
Transcript variation has important implications for organismal function in health and disease. Most transcriptome studies focus on assessing variation in gene expression levels and isoform representation. Variation at the ...
Neuropsychological Test Performance in Cognitively Normal Spanish-speaking Nonagenarians with Little Education
To find associations of age, sex, and education with neuropsychological test performance in cognitively normal Spanish-speaking Costa Rican nonagenarians with little education; to provide norms; and to compare their ...
