(2014-07)East Pacific green turtles (Chelonia mydas), often referred to as black turtles, are smaller and exhibit a lower reproductive output than other populations of green turtles in the Atlantic, Indian and Western Pacific Oceans. ... -
Neurobrucellosis in stranded dolphins, Costa Rica
(Universidad Nacional, Costa Rica, 2008-09)Ten striped dolphins, Stenella coeruleoalba, stranded along the Costa Rican Pacifi c coast, had meningoencephalitis and antibodies against Brucella spp. Brucella ceti was isolated from cerebrospinal fl uid of 6 dolphins ... -
Neuroinvasion of the highly pathogenic influenza virus H7N1 is caused by disruption of the blood brain barrier in an avian model
(PLOS ONE, 2014-12-15)Influenza A virus (IAV) causes central nervous system (CNS) lesions in avian and mammalian species, including humans. However, the mechanism used by IAV to invade the brain has not been determined. In the current work, we ... -

Escuela de Literatura y Ciencias del Lenguaje, 2016)Produce un texto meta de la versión al inglés de un pasaje de la novela “La fugitiva” utilizando estrategias de traducción para su neutralización. Los objetivos específicos son: reformular en inglés aspectos sintácticos, ... -
Neutralización del efceto hemorrágico inducido por veneno Bothrops asper (Serpentes: Viperidae) por extractos de las plantas tropicales
(Universidad Nacional (Costa Rica), 1999)Organic extracts representing 48 species included in 30 families of Costa Rican tropical plants were evaluated for their hability to neutralize hemorrhagic acfivity lnduced by the venom of the snake Bothrops aspero Abioassay ... -
Neutralizing antibodies against vesicular stomatitis viruses (serotypes New Jersey and Indiana) in horses in Costa Rica
(AAVLD, 2002-09-01)Serum samples were collected from domestic horses in 4 different regions of Costa Rica to detect antibodies against vesicular stomatitis viruses, serotypes New Jersey (VSV-NJ) and Indiana (VSV-IN). A total of 214 samples ... -
Neutrophils as Trojan Horse vehicles for Brucella abortus macrophage infection
(Universidad Nacional, Costa Rica, 2019-05-07)Brucella abortus is a stealthy intracellular bacterial pathogen of animals and humans. This bacterium promotes the premature cell death of neutrophils (PMN) and resists the killing action of these leukocytes. B. abortus-infected ... -
Neutrophils dampen adaptive immunity in Brucellosis
(American Society For Microbiology, 2019-04-23)Brucella organisms are intracellular stealth pathogens of animals and humans. The bacteria overcome the assault of innate immunity at early stages of an infection. Removal of polymorphonuclear neutrophils (PMNs) at the ... -
Neutrophils exert a suppressive effect on Th1 responses to intracellular pathogen Brucella abortus
(PLoS Pathogens, 2013-02-14)Polymorphonuclear neutrophils (PMNs) are the first line of defense against microbial pathogens. In addition to their role in innate immunity, PMNs may also regulate events related to adaptive immunity. To investigate the ... -
New advances in the method validation, extraction methods and measurement uncertainty for the determination of water-soluble hexavalent chromium in hydraulic cemen
(Elsevier, 2021)The quantification of Cr (VI) in the cement matrix is highly important, given the possibility of suffering illnesses including dermatitis, induced nasal carcinoma, and DNA damage produced by inhalation of and/or direct ... -

New and common haplotypes shape genetic diversity in Asian tiger mosquito populations from Costa Rica and Panama
(Oxford University Press, 2015)The Asian tiger mosquito, Aedes albopictus (Skuse) (Diptera: Culicidae), is a vector of sev eral human pathogens. Ae. albopictus is also an invasive species that, over recent years, has expanded its range out of its native ... -
New Bruce-ladder multiplex PCR assay for the biovar typing of Brucella suis and the discrimination of Brucella suis and Brucella canis
(Veterinary Microbiology, 2011-06-11)Rapid and specific identification of Brucella suis at the biovar level is necessary because some of the biovars that infect animals are pathogenic for humans. None of the molecular typing methods described so far are ... -
