Hidrocarburos cuticulares: su potencial como estímulo para el reconocimiento de parentela en dos arañas subsociales anelosimus (Araneae: Theridiidae) y patrones de fijación de hilos de seda en la araña subsocial Anelosimus baeza (Araneae: Theridiidae)
(2019-09-27)El reconocimiento de parentela en grupos sociales de artrópodos puede ocurrir por diferentes tipos de estímulos, como por ejemplo los compuestos excretados de la cutícula. Un rasgo posiblemente ancestral de las arañas ... -

Hierarchical spatial patterns in Caribbean reef benthic assemblages
(2015)Aim: Coral assemblages on Caribbean reefs have largely been considered to be biogeographically homogeneous at a regional scale. We reassess this in three taxa (corals, sponges and octocorals) using three community attributes ... -
High 18:2 trans fatty acids are associated with increased risk of nonfatal acute myocardial infarction in Costa Rican adults
(2003)Trans-fatty acid intake is associated with coronary heart disease (CHD), but the atherogenic potential of individual trans-fatty acids (FA) from partially hydrogenated oils (18:1 and 18:2) or meat and dairy products (16:1 ... -
High and low affinity sites of ferrihydrite for metal ion adsorption: Data and modeling of the alkaline-earth ions Be, Mg, Ca, Sr, Ba, and Ra
(2020-10-01)The alkaline-earth metal ion series comprises Be, Mg, Ca, Sr, Ba, and Ra. Calcium (Ca) and magnesium (Mg) are the most abundant alkaline-earth metal ions in nature and their interaction with the mineral surfaces of metal ... -
High Efficacy of Therapeutic Equine Hyperimmune Antibodies Against SARS-CoV-2 Variants of Concern
(2021)SARS-CoV-2 variants of concern show reduced neutralization by vaccine-induced and therapeutic monoclonal antibodies; therefore, treatment alternatives are needed. We tested therapeutic equine polyclonal antibodies (pAbs) ... -
High levels of somatic DNA diversity at the myotonic dystrophy type 1 locus are driven by ultra-frequent expansion and contraction mutations
(Human Molecular Genetics, 2012, Vol. 21, No. 11 2450–2463, 2012-02-24)Several human genetic diseases are associated with inheriting an abnormally large unstable DNA simple sequence repeat. These sequences mutate, by changing the number of repeats, many times during the lifetime of those ... -
High life expectancy and reversed socioeconomic gradients of elderly people in Mexico and Costa Rica
(2018-01)Background: Some existing estimates suggest, controversially, that life expectancy at age 60 (LE60) of Latin American males is exceptionally high. Knowledge of adult mortality in Latin America is often based on unreliable ... -
High mitochondrial mutation rates estimated from deep-rooting Costa Rican pedigrees
(American Journal of Physical Anthropology 2012 July ; 148(3): 327–333., 2012-07)Estimates of mutation rates for the noncoding hypervariable Region I (HVR-I) of mitochondrial DNA (mtDNA) vary widely, depending on whether they are inferred from phylogenies (assuming that molecular evolution is clock-like) ... -
High Performance Graphene–Oxide–Metal Diode through Bias‐Induced Barrier Height Modulation
(2016)Graphene–oxide–metal diodes are presented whose performance is preserved even for thin oxide layers, as required for high frequency applications. The diodes, which rely upon bias-induced modulation of graphene's work ... -
High Prevalence of Multidrug-Resistant Community-Acquired Methicillin-Resistant Staphylococcus aureus at the Largest Veterinary Teaching Hospital in Costa Rica
(2017-08-17)Methicillin-resistant Staphylococcus aureus (MRSA) is a pathogen associated with severe infections in companion animals present in the community, and it is diagnosed in animals admitted to veterinary hospitals. However, ... -
High quality 3C de novo assembly and annotation of a multidrug resistant ST-111 Pseudomonas aeruginosa genome: Benchmark of hybrid and non-hybrid assemblers
(2020)Genotyping methods and genome sequencing are indispensable to reveal genomic structure of bacterial species displaying high level of genome plasticity. However, reconstruction of genome or assembly is not straightforward ... -
High relational mobility is associated with perceiving more economic inequality in everyday life
(2024)In this paper, we argue that one of the variables that may influence perceived inequality in everyday life is cultural differences in relational mobility. We examined this research question across two cross-cultural studies ... -
High resolution analysis of snake venom metalloproteinase (SVMP) peptide bond cleavage specificity using proteome based peptide libraries and mass spectrometry
(2011-04-01)Both serine and metalloproteinases have been shown to play the role of toxins in the venoms of many snakes. Determination of the natural protein substrates of these toxins is an important feature in the toxinological ...
