(2020)The objectives of this study were to estimate sodium intake and to identify the main dietary sources of this nutrient in young people. Cross-sectional study performed in 2685 students from 64 schools and high-schools of ... -
SARS-CoV-2 genomic surveillance in Costa Rica: Evidence of a divergent population and an increased detection of a spike T1117I mutation
(2021)Genome sequencing is a key strategy in the surveillance of SARS-CoV-2, the virus responsible for the COVID-19 pandemic. Latin America is the hardest-hit region of the world, accumulating almost 20% of COVID-19 cases ... -
Scarce detection of mobile erm genes associated with tetQ in Bacteroides and Parabacteroides from Costa Rica
(2013-06)The frequency of finding of clindamycin-resistant anaerobic bacteria in clinical samples has doubled from 2008 to 2010 in Costa Rica. To determine whether this increase is due to dissemination of erm genes aided by tetQ ... -
Screening for target toxins of the antiophidic protein DM64 through a gel-based interactomics approach
(2017-01)DM64 is a glycosylated protein with antivenomactivity isolated fromthe serum of the opossumDidelphis aurita. It binds non-covalently to myotoxins I (Asp49) and II (Lys49) from Bothrops asper venom and inhibits their myotoxic ... -
SDS‑induced hexameric oligomerization of myotoxin‑II from Bothrops asper assessed by sedimentation velocity and nuclear magnetic resonance
(2023)We report the solution behavior, oligomerization state, and structural details of myotoxin-II purified from the venom of Bothrops asper in the presence and absence of sodium dodecyl sulfate (SDS) and multiple lipids, as ... -
Seasonal profiles of Aedes aegypti (Diptera: Culicidae) larval habitats in an urban area of Costa Rica with a history of mosquito control
(2008-06-01)Dengue is the most important arboviral disease worldwide and the principal vector-borne disease in Costa Rica. Control of Aedes aegypti populations through source reduction is still considered the most effective way of ... -
Seasonal wetlands in the Pacific coast of Costa Rica and Nicaragua: environmental characterisation and conservation status
(2015)On the Pacific coast of Nicaragua and Costa Rica, rainfall patterns and clay-rich soils allow the development of extensive wetlands. These environments constitute unique habitats for the maintenance of aquatic biodiversity ... -
Second generation snake antivenomics: Comparing immunoaffinity and immunodepletion protocols
(2012-09-15)A second generation antivenomics protocol, based on affinity chromatography, was compared with a previously (first generation) immunodepletion protocol using as a proof of principle the pan-African EchiTAb-Plus-ICP® IgG ... -
Secretory phospholipases A2 isolated from Bothrops asper and from Crotalus durissus terrificus snake venoms induce distinct mechanisms for biosynthesis of prostaglandins E2 and D2 and expression of cyclooxygenases
(2008-09-01)The effects of myotoxin III (MT-III), a phospholipase A2 (sPLA2) from Bothrops asper snake venom, and crotoxin B (CB), a neurotoxic and myotoxic sPLA2 from the venom of Crotalus durissus terrificus, on cyclooxygenases ... -
Selecting key toxins for focused development of elapid snake antivenoms and inhibitors guided by a Toxicity Score
(2015-09-15)For more than 100 years, antivenoms have been produced by traditional methods of immunization of large mammals with mixtures of snake venoms (World Health Organization, 2010 and Gutiérrez et al., 2011). With the introduction ... -
