Análisis electroforético del Ácido Ribonucleico de rotavirus de Costa Rica: implicaciones epidemiológicas
(Revista Médica del Hospital Nacional de Niños Dr. Carlos Sáenz Herrera: 15(1), 21-30, 1980)Actualmente los rotavirus constituyen los principales agentes etiológicos de las diarreas. Fueron descubiertos mediante la microscopía electrónica en 1973 (1, 5, 6) y por su morfología se denominaron partículas virales ... -
Análisis ultraestructural de membranas de glóbulos grasos lácteos de calostro y leche humana
(Revista de Biología Tropical 31(2):245-250, 1983)Lacteous fat globules with their membranes from human milk and calostrum were studied by scanning and transmission electron microscopy. The first appear as spheroidal structures with some irregularities on the surface. ... -
Anemias hemolíticas por autoinmunidad y por mecanismos inmunes inducidos por medicamentos
(1981)En la presente revisión sobre anemias hemolíticas por autoinmunidad (AHA) y por trastornos inmunes inducidos por drogas o medicamentos, se han considerado aspectos etiológicos, físiopatológicos, una metodología ... -
Ant microbial symbionts are a new model for drug discovery
(2019)Ants have been widely studied, with 14,000 described species, but it is not until recently that they gained attention as sources for antimicrobial drug discovery. An increasing amount of studies are investigating ant-microbe ... -
Anthropogenic activities and the problem of antibiotic resistance in Latin America: a water issue
(2021)Antibiotics revolutionized modern medicine and have been an excellent tool to fight infections. However, their overuse and misuse in different human activities such as health care, food production and agriculture has ... -
Anti-human erythrocyte antibodies in horse-derived antivenoms used in the treatment of snakebite envenomations
(2007-03)This work examined the presence of antibodies reacting with human erythrocytes in horse-derived antivenoms used in the treatment of snakebite envenomations, and assessed the efficacy of various fractionation protocols in ... -
Anti-rotavirus antibody in human colostrum
(The Lancet 311(8054), 7 January 1978, Pages 39–40. Originally published as Volume 1, Issue 8054, 1978)During investigation of the epidemiology of human rotavirus infection in Costa Rica, the anti-human rotavirus capacity of colostrum was studied. We were looking for an explanation for the relatively low incidence of acute ... -
Antibiotics do not affect the degradation of fungicides and enhance the mineralization of chlorpyrifos in biomixtures
(2017)The use of antibiotics in agriculture produces residues in wastewaters. The disposal of such wastewaters in biopurification systems (BPS) employed for the treatment of pesticides could result in the inhibition of the ... -
Antibodies against a single fraction of Micrurus dumerilii venom neutralize the lethal effect of whole venom
(2023-02-01)The coralsnake Micrurus dumerilii (Elapidae) is reported to cause envenomings of medical importance. Previous studies characterized the protein composition of its venom, with phospholipase A2 (PLA2) proteins the most ... -
Antibody neutralization of a myotoxin from the venom of Bothrops asper (terciopelo)
(1987)Neutralization of biological activities of B. asper myotoxin by a monospecific anti-myotoxin rabbit serum and polyvalent antivenom was studied. Both antisera neutralized myotoxic, phospholipase A and lethal activities of ... -
Antibody-dependent enhancement of toxicity of myotoxin II from Bothrops asper
(2024)Improved therapies are needed against snakebite envenoming, which kills and permanently disables thousands of people each year. Recently developed neutralizing monoclonal antibodies against several snake toxins have ... -
Antibody-mediated neutralization and binding-reversal studies on α-neurotoxins from micrurus nigrocinctus nigrocinctus (coral snake) venom
(1996-03)An ELISA based, non-radioactive acetylcholine receptor (AchR) binding assay was used to detect the alpha-neurotoxins present in Micrurus nigrocinctus nigrocinctus venom. Sera from horses hyperimmunized against M. nigrocinctus ... -
Anticomplementary activity of equine whole IgG antivenoms: comparison of three fractionation protocols
(2005-01)Early adverse reactions occur in a number of patients treated with heterologous antivenoms and have been associated with anticomplementary activity (ACA). In order to reduce the ACA of equine whole IgG antivenoms produced ... -
Anticomplementary Activity of Horse IgG and F(ab’)2 Antivenoms
(2014)Envenomation by poisonous animals is a neglected condition according to the World Health Organization (WHO). Antivenoms are included in the WHO Essential Medicines List. It has been assumed that immunoglobulin G (IgG) ... -
Anticuerpos IgE específicos de alergenos comunes en niños costarricenses
(Alergia, Asma e Inmunología Pediátricas :13 (2); p 40-43, 2004-05)La morbilidad por asma y otras enfermedades alérgicas aumentan cada año y un factor muy importante es la exposición a niveles elevados de alergenos interiores. En el presente estudio se evaluó la prevalencia y la exposición ... -
Antimicrobial activity of myotoxic phospholipases A2 from crotalid snake venoms and synthetic peptide variants derived from their C-terminal region
(2005)A short peptide derived from the C-terminal region of Bothrops asper myotoxin II, a Lys49 phospholipase A2 (PLA2), was previously found to reproduce the bactericidal activity of its parent molecule. In this study, a panel ...
