Venomic analysis of the poorly studied desert coral snake, Micrurus tschudii tschudii, supports the 3FTx/PLA2 dichotomy across Micrurus venoms
(2016)The venom proteome of the poorly studied desert coral snake Micrurus tschudii tschudii was unveiled using a venomic approach, which identified ¥38 proteins belonging to only four snake venom protein families. The ... -
Venomic and antivenomic analyses of the Central American coral snake, Micrurus nigrocinctus (Elapidae)
(2011-01-31)The proteome of the venom of Micrurus nigrocinctus (Central American coral snake) was analyzed by a “venomics” approach. Nearly 50 venom peaks were resolved by RP-HPLC, revealing a complex protein composition. Comparative ... -
Venomics and antivenomics of Bothrops erythromelas from five geographic populations within the Caatinga ecoregion of northeastern Brazil
(2015-01-30)The Caatinga lancehead, Bothrops erythromelas, is a medically relevant species, responsible for most of the snakebite accidents in most parts of its distribution range in northeastern Brazil. The spectrum and geographic ... -
Venomics of Leiurus abdullahbayrami, the most lethal scorpion in the Levant region of the Middle East
(2024)The scorpion Leiurus abdullahbayrami has been associated with severe/lethal envenomings throughout the Levant region of the Middle East, encompassing Turkey, Syria, and Lebanon, and only scarce information is available on ... -
Venomics of the Central American Lyre snake Trimorphodon quadruplex (Colubridae: Smith, 1941) from Costa Rica
(2020)Rear-fanged colubrid snakes include hundreds of species globally that possess a Duvernoy's venom gland and often one-several enlarged rear maxillary teeth. We investigated the venom proteome of the Central American Lyre ... -
Venomics of the Duvernoy's gland secretion of the false coral snake Rhinobothryum bovallii (Andersson, 1916) and assessment of venom lethality towards synapsid and diapsid animal models
(2020)The Duvernoy's gland secretory proteome of the false coral snake Rhinobothryum bovallii (Costa Rica), unveiled applying bottom-up venomics, comprises a handful of toxins belonging to only three protein families, three-finger ... -
Venomics of the poorly studied hognosed pitvipers Porthidium arcosae and Porthidium volcanicum
(2021)We report the first proteomics analyses of the venoms of two poorly studied snakes, the Manabi hognosed pitviper Porthidium arcosae endemic to the western coastal province of Manabí (Ecuador), and the Costa Rican hognosed ... -
Venomics of the scorpion Tityus ocelote (Scorpiones, Buthidae): Understanding venom evolution in the subgenus Archaeotityus
(2022)The subgenus Tityus (Archaeotityus) includes small variegated species considered until recently, a basal group within Tityus, one of the most diverse and medically relevant genera of scorpions in the New World. Archaeotityus ... -
Venoms of Micrurus coral snakes: evolutionary trends in compositional patterns emerging from proteomic analyses
(2016-11)The application of proteomic tools to the study of snake venoms has led to an impressive growth in the knowledge about their composition (venomics), immunogenicity (antivenomics), and toxicity (toxicovenomics). About ... -
Verificación del punto de corte de la prueba cualitativa para la determinación de sangre oculta y comparación de resultados con una determinación automatizada de hemoglobina en heces
(2020-12-15)El cáncer colorrectal es una enfermedad de alta incidencia en el mundo y Costa Rica no es la excepción, por lo que se han implementado programadas de tamizaje para poblaciones de riesgo. Se busca detectar las pérdidas ... -
Violent and risk-taking behaviors associated with intake of energy drinks mixed with alcohol and perceptions of this consumption among children and adolescents in Costa Rica
(2020-08-28)Introduction: The consumption of energy drinks and its mix with alcohol has been associated with negative and violent behaviors in youngsters. Objective: Determine the risk-taking behaviors associated with the consumption ... -
Virulent Brucella nosferati infecting Desmodus rotundus has emerging potential due to the broad foraging range of its bat host for humans and wild and domestic animals
(2023)Desmodus rotundus, vampire bats, transmit dangerous infections, and brucellosis is a hazardous zoonotic disease, two adversities that coexist in the subtropical and tropical areas of the American continent. Here, we report ... -
Virus del Epstein-Barr y su relacion con el desarrollo de sindromes linfoproliferativos, especificamente el linfoma de Hodgkin, el linfoma de Burkitt y los desordenes linfoproliferativos postrasplante
(2021-08-03)El virus del Epstein-Barr (EBV) es un herpes humano 4 extendido por toda la población mundial y se transmite como una infección asintomática latente en la gran mayoría de las personas. Sin embargo, este mismo virus es un ... -
El virus del Zika
(2016-01)El virus del Zika es un arbovirus emergente. Se transmite por medio de los mosquitos del género Aedes. Fue descrito por primera vez en mosquitos y monos del bosque Zika en Uganda, en 1947; posteriormente, en seres humanos ... -
Wastewater-based epidemiology of enteric viruses and surveillance of acute gastrointestinal illness outbreaks in a resource-limited region
(2021)Acute gastrointestinal illness (AGI) continues to be an important cause of morbidity and mortality among all ages. This study applied the principles ofwastewater-based epidemiology for the preventive identification of ... -
Welcome to the Atta world: A framework for understanding the effects of leaf‐cutter ants on ecosystem functions
(2019)1. Leaf‐cutter ants are a prominent feature in Neotropical ecosystems, but a comprehensive assessment of their effects on ecosystem functions is lacking. We reviewed the literature and used our own recent findings to ... -
What lies behind the curtain: Cryptic diversity in helminth parasites of human and veterinary importance
(2022)Parasite cryptic species are morphologically indistinguishable but genetically distinct organisms, leading to taxa with unclear species boundaries. Speciation mechanisms such as cospeciation, host colonization, taxon ... -
