Aging of biomixtures: Effects on carbofuran removal and microbial community structure
(2017)The aim of this work was to determine the efficiency of a straw/compost/soil biomixture for pesticide depuration during its aging and continuous use, for a period of over a year, based on its capacity to remove carbofuran ... -
Alpha-thalassemia. Case report alpha-thalassemia in a Costa Rican family, A case report
(2020-11-26)This case report highlights the importance for health care providers to be aware of the αlpha‐thalassemia syndromes, their relevance to clinical care and family counseling, appropriate diagnostic algorithm for definitive ... -
Alteraciones en la microvasculatura y papel en la inflamación de la hemorragia pulmonar inducida por Csh1, una metaloproteinasa del veneno de la serpiente Crotalus simus
(2019-10)El envenenamiento inducido por mordeduras de serpiente afecta a millones de personas cada año, principalmente de poblaciones rurales vulnerables y la Organización Mundial de la Salud lo ha identificado como una enfermedad ... -
Alterations in common marmoset gut microbiome associated with duodenal strictures
(2022-03-28)Chronic gastrointestinal (GI) diseases are the most common diseases in captive common marmosets (Callithrix jacchus). Despite standardized housing, diet and husbandry, a recently described gastrointestinal syndrome ... -
Amebas de vida libre como agentes de encefalitis en el ser humano
(2014-07)Este artículo de revisión se enfoca en las amebas de vida libre, un tipo de protozoarios que habitan diferentes tipos de suelo y fuentes de agua. Estos organismos tienen dos estadios evolutivos: trofozoíto y quiste, siendo ... -
Amino acid sequence and biological characterization of BlatPLA2, a non-toxic acidic phospholipase A2 from the venom of the arboreal snake Bothriechis lateralis from Costa Rica
(2013-10)Bothriechis is considered a monophyletic, basal genus of arboreal Neotropical pitvipers distributed across Middle America. The four species found in Costa Rica (B. lateralis, B. schlegeli, B. nigroviridis, B. supraciliaris) ... -
Amino acid sequence and crystal structure of BaP1, a metalloproteinase from Bothrops asper snake venom that exerts multiple tissue-damaging activities
(2003-10)BaP1 is a 22.7-kD P-I-type zinc-dependent metalloproteinase isolated from the venom of the snake Bothrops asper, a medically relevant species in Central America. This enzyme exerts multiple tissue-damaging activities, ... -
Amino acid sequence of a myotoxic Lys49-phospholipase A2 homologue from the venom of Cerrophidion (Bothrops) godmani
(1998-05-19)The complete amino acid sequence of myotoxin II (godMT-II), a myotoxic phospholipase A2 (PLA2) homologue from the venom of the Central American crotaline snake Cerrophidion (Bothrops) godmani, was determined by direct ... -
An acidic phospholipase A2 with antibacterial activity from Porthidium nasutum snake venom
(2012-04)Snake venoms are complex mixtures of proteins among which both basic and acidic phospholipases A2 (PLA2s) can be found. Basic PLA2s are usually responsible for major toxic effects induced by snake venoms, while acidic ... -
An alternative in vitro method for testing the potency of the polyvalent antivenom produced in Costa Rica
(1988)The ability of several batches of polyvalent antivenom to neutralize indirect hemolytic activity of Bothrops asper venom was studied using a sensitive plate test. All samples of antivenom tested effectively neutralized ... -
An Asp49 Phospholipase A2 from Snake Venom Induces Cyclooxygenase-2 Expression and Prostaglandin E2 Production via Activation of NF-κB, p38MAPK, and PKC in Macrophages
(2014)Phospholipases A2 (PLA2) are key enzymes for production of lipid mediators. We previously demonstrated that a snake venom sPLA2 named MT-III leads to prostaglandin (PG)E2 biosynthesis in macrophages by inducing the expression ... -
An electrophoretic study on phospholipase A2 isoenzymes in the venoms of Central American crotaline snakes
(1992)The number and isoelectric points of phospholipase A2 isoenzymes were studied in the venoms of 12 Central American crotaline snakes of the genera Bothrops, Crotalus, Lachesis and Agkistrodon. The study was carried out by ... -
An interactive database for the investigation of high-density peptide microarray guided interaction patterns and antivenom cross-reactivity
(2020)Snakebite envenoming is a major neglected tropical disease that affects millions of people every year. The only effective treatment against snakebite envenoming consists of unspecified cocktails of polyclonal antibodies ... -
An MTT-based method for the in vivo quantification of myotoxic activity of snake venoms and its neutralization by antibodies
(1993-05)The reduction of the tetrazolium compound MTT (3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyl-tetrazolium bromide) was used as the basis for the development of a simple method for the quantitative estimation of metabolically ... -
An overview of Lysine-49 phospholipase A2 myotoxins from crotalid snake venoms and their structural determinants of myotoxic action
(2003)In 1984, the first venom phospholipase A2 (PLA2) with a lysine substituting for the highly conserved aspartate 49 was discovered, in the North American crotalid snake Agkistrodon p. piscivorus [J. Biol. Chem. 259 (1984) ... -
