Morphological and molecular characterization of Paragonimus caliensis Little, 1968 (Trematoda: Paragonimidae) from Medellin and Pichinde, Colombia.

Paragonimiasis is a subacute to chronic inflammatory granulomatous lung disease caused by the genus Paragonimus. In Latin America Paragonimus mexicanus Miyazaki & Ishii, 1968 is the only confirmed species to cause human infections. Paragonimus caliensis Little, 1968 is an uncommon species often regarded as a synonym of P. mexicanus. Recently, the study of two types of Paragonimus metacercariae from Costa Rica has provided new molecular and morphological evidence that P. caliensis is a separate species from ...

Seasonality effect on the composition of oxindole alkaloids from distinct organs of Uncaria tomentosa from the Caribbean region of Costa Rica.

Uncaria tomentosa (Willd.) D.C. (Rubiaceae), commonly known as "Uña de Gato" or "Cat's Claw", is a tropical vine from the rainforest used in traditional medicine and spread through Central and South America, including Costa Rica. There is an increasing demand for medicinal extracts with biological activity attributed mainly to oxindole alkaloids (OA), where the ratio between tetracyclic (TOA) and pentacyclic oxindole alkaloids (POA) determines its feasibility for medicinal applications. The ratio is affect...


Taxonomy and phylogeny of Pyrrhoderma: a redefinition, the segregation of Fulvoderma, gen. nov., and identifying four new species.

Previously, Pyrrhoderma accommodated two polypore species, P. adamantinum and P. scaurum; however, phylogenetic studies indicated that these two species were not congeneric within the Hymenochaetaceae and that P. adamantinum formed a clade with Phellinidium noxium. To resolve the relationships among the two species of Pyrrhoderma and other related taxa, specimens from China, Costa Rica, Singapore, and Thailand were studied from both morphological and phylogenetic perspectives. A new genus, Fulvoderma, is er...

Prevalence and Severity of Dental Caries in Foster-Care Children and Adolescents.

Molecular epidemiology and antimicrobial resistance of Clostridium difficile in a National Geriatrics Hospital from Costa Rica.

The epidemiology of Clostridium difficile infections (CDI) is changing rapidly worldwide; knowledge of the genotypes of C. difficile circulating in specialized geriatric hospitals and their resistance to antibiotics is scarce or non-existent.

Intragenomic nuclear RNA variation in a cryptic Amanita taxon.

Amanita cf. lavendula collections in eastern North America, Mexico, and Costa Rica were found to consist of four cryptic taxa, one of which exhibited consistently unreadable nuclear rDNA ITS1-5.8S-ITS2 (fungal barcode) sequences after ITS1 base 130. This taxon is designated here as Amanita cf. lavendula taxon 1. ITS sequences from dikaryotic basidiomata were cloned, but sequences recovered from cloning did not segregate into distinct haplotypes. Rather, there was a mix of haplotypes that varied among themse...

Functional Precision Polymers via Stereo- and Regioselective Polymerization Using Group 6 Metal Alkylidene and Group 6 and 8 Metal Alkylidene N-Heterocyclic Carbene Complexes.

The concepts of functional precision polymers and the latest accomplishments in their synthesis are summarized. Synthetic concepts based on chain growth polymerization are compared to iterative synthetic approaches. Here, the term "functional precision polymers" refers to polymers that are not solely hydrocarbon-based but contain functional groups and are characterized by a highly ordered primary structure. If insertion polymerization is used for their synthesis, olefin metathesis-based polymerization techn...

Venom gland transcriptomics and microRNA profiling of juvenile and adult yellow-bellied sea snake, Hydrophis platurus, from Playa del Coco (Guanacaste, Costa Rica).

With an extensive range in tropical and subtropical waters of Indo-Australian region and the Pacific coast of the American continent, the yellow-bellied sea snake, Hydrophis platurus, is the most broadly distributed snake species on our planet. We report a comparative analysis of the mRNA and microRNA transcriptional profiles of the venom glands of Costa Rican juvenile and adult yellow-bellied sea snakes, and correlate these datasets with the previously reported venom proteome gathered from an adult specime...

A new species of Astyanax (Characiformes: Characidae) from Costa Rica and Panama, with a key to the lower Central American species of the genus.

Astyanax anai, a new species of characid fish, is described from the Sixaola River basin, eastern Costa Rica-western Panama, Central America. The new species can be distinguished from all other congeners by the following combination of characters: premaxillary teeth 4-5 at the inner series and 4-6 at the outer series; maxillary teeth tricuspid, 2-4; predorsal scale series irregular and incomplete, with an unscaled space behind tip of supraoccipital process and 12-14 scales; lateral line scales 34-39; humera...

A Practice-Oriented Review of Health Concepts.

Whereas theories on health generally argue in favor of one specific concept, we argue that, given the variety of health practices, we need different concepts of health. We thus approach health concepts as a Wittgensteinian family of thick concepts. By discussing five concepts of health offered by (philosophical) theory, we argue that all capture something that seems relevant when we talk and think about health. Classifying these concepts reveals their family resemblances: each of these concepts differs from...

Pansusceptible Escherichia coli isolates obtained from feces of free-ranging Baird's Tapirs (Tapirus bairdii), suggests a low selective pressure of resistant determinants, in the North-western region of the Talamanca Mountain Range, Costa Rica.

The main objective of this study was to analyze the antibiotic susceptibility profile of Escherichia coli isolates obtained from fecal samples of free-ranging Baird's tapirs (Tapirus bairdii) in the North-western region of the Talamanca Mountain Range.

Lack of alkaloids and tetrodotoxin in the neotropical frogs Allobates spp. (Aromobatidae) and Silverstoneia flotator (Dendrobatidae).

Frogs of the family Dendrobatidae are known to contain toxic alkaloids in their skin secretion, but Allobates species of the closely related Aromobatidae family are considered to lack toxic secretions. However, contradictory results have been reported. Analyses of alcohol extracts from three different Allobates species from South-America (Guiana Shield), Central America (Costa Rica), and from the dendrobatid frog Silverstoneia flotator confirm the absence of alkaloids and tetrodotoxin in aromobatids and in ...

Interethnic Variability in CYP2D6, CYP2C9, and CYP2C19 Genes and Predicted Drug Metabolism Phenotypes Among 6060 Ibero- and Native Americans: RIBEF-CEIBA Consortium Report on Population Pharmacogenomics.

Pharmacogenetic variation in Latin Americans is understudied, which sets a barrier for the goal of global precision medicine. The RIBEF-CEIBA Network Consortium was established to characterize interindividual and between population variations in CYP2D6, CYP2C9, and CYP2C19 drug metabolizing enzyme genotypes, which were subsequently utilized to catalog their "predicted drug metabolism phenotypes" across Native American and Ibero American populations. Importantly, we report in this study, a total of 6060 heal...

Snakebites in French Guiana: Conclusions of an international symposium.

A workshop on epidemiology and management of snakebites in French Guiana was performed at Cayenne, French Guiana from September 15 to September 16, 2017, under the auspices of the French Regional Health Agency (ARS) and the Pan American Health Organization (PAHO). The activity was attended by experts from France (Angers, Martinique, French Guiana, Guadeloupe, and Paris), Costa Rica, Brazil, Saint Lucia, and Surinam. The epidemiology, clinical manifestations, clinical grading and the management of snakebite ...

Complex overlapping concepts: An effective auditing methodology for families of similarly structured BioPortal ontologies.

In previous research, we have demonstrated for a number of ontologies that structurally complex concepts (for different definitions of "complex") in an ontology are more likely to exhibit errors than other concepts. Thus, such complex concepts often become fertile ground for quality assurance (QA) in ontologies. They should be audited first. One example of complex concepts is given by "overlapping concepts" (to be defined below.) Historically, a different auditing methodology had to be developed for every s...

Molecular phylogenetics of Neotropical detritivorous fishes of the family Curimatidae (Teleostei: Characiformes).

Curimatidae, the fourth largest family of detritivorous Neotropical characiform fishes, encompasses eight extant genera and over 110 species dwelling in diverse freshwater habitats from Costa Rica to Argentina. Extensive phylogenetic analyses of soft anatomy and osteology provided evidence for intergeneric and most interspecific relationships, and formed the basis of curimatid taxonomy for nearly 40 years. However, that morphological phylogeny demonstrated incomplete phylogenetic resolution at various scale...

Determinants of Soil Bacterial and Fungal Community Composition Toward Carbon-Use Efficiency Across Primary and Secondary Forests in a Costa Rican Conservation Area.

Tropical secondary forests currently represent over half of the world's remaining tropical forests and are critical candidates for maintaining global biodiversity and enhancing potential carbon-use efficiency (CUE) and, thus, carbon sequestration. However, these ecosystems can exhibit multiple successional pathways, which have hindered our understanding of the soil microbial drivers that facilitate improved CUE. To begin to address this, we examined soil % C; % N; C:N ratio; soil microbial biomass C (C); NO...

Precision Surgery for Obesity.

Precision medicine is targeted towards improving the effectiveness of treatment, reducing the side effects of drugs and reducing medical costs. The application of precision surgery for obesity is a new concept that involves 2 stages: the first stage is to attain a precise obesity surgery, and the second stage is to achieve individualized obese gene therapy. In this article, we discuss the value of precision surgery for obesity, its stages and its future application to improve obesity surgery. Due to recent ...

Distinguishing the precision of spatial recollection from its success: Evidence from healthy aging and unilateral mesial temporal lobe resection.

Successful episodic recollection can vary in the precision of the information recalled. The hypothesis that recollection precision requires functional neuroanatomical contributions distinct from those required for recollection success remains controversial. Some findings in individuals with hippocampal lesions have indicated that precision is dependent on the hippocampus. However, other neuroimaging and lesion studies have implicated regions outside of the mesial temporal lobe (MTL) in precision, such as pa...

Learning to become a primary care professional: insights from threshold concept theory.

Threshold Concepts are fundamental ideas within a discipline which are transformative, integrative, irreversible and usually troublesome. This article describes the threshold concept framework and discusses how it can offer new insights into how we focus teaching and facilitate learning around these concepts, such as uncertainty. Relevant research from a range of health disciplines are explored to consider which concepts may be critical to thinking and practising effectively in primary care. In addition, it...

Thyroid Cancer "Epidemic" also Occurs in Low- and Middle-income countries.

Thyroid cancer incidence varies greatly between and within high-income countries (HICs), and overdiagnosis likely plays a major role in these differences. Yet, little is known about the situation in low- and middle-income countries (LMICs). We compare up-to-date thyroid cancer incidence and mortality at national and subnational levels. 599,851 thyroid cancer cases in subjects aged 20-74 reported in Cancer Incidence in Five Continents volume XI from 55 countries with at least 0.5 million population, aged 20-...

Electrospun plant mucilage nanofibers as biocompatible scaffolds for cell proliferation.

Electrospun nanofibers (ESNFs) were prepared from mucilage isolated from chan and linaza beans and mozote stem commercially available in Costa Rica. Poly(vinyl alcohol) (PVA) was used as an aiding agent. Mucilage/PVA mixed solutions of different volume ratios (100:0, 80:20, 60:40, 40:60, 20:80 and 0:100) were prepared and adjusted to be similar in viscosity and electrical conductivity suitable for electrospinning. Morphology of the ESNFs was examined using scanning electron microscopy (SEM). Fourier transfo...
