Arcobacter Isolation from Minced Beef Samples in Costa Rica
(2017)The presence of Arcobacter spp. in minced meat (including beef) samples has been well documented in different countries, with varying frequencies. Nevertheless, the only Latin American country reporting this bacterium in ... -
Arcobacter: Comparison of Isolation Methods, Diversity, and Potential Pathogenic Factors in Commercially Retailed Chicken Breast Meat from Costa Rica
(2014)Arcobacter species have been recognized as potential food- and waterborne pathogens. The lack of standardized isolation methods and the relatively scarce knowledge about their prevalence and distribution as emerging pathogens ... -
Articular inflammation induced by an enzymatically-inactive Lys49 phospholipase A2: activation of endogenous phospholipases contributes to the pronociceptive effect
(2017-03-23)Arthritis is a set of inflammatory conditions that induce aching, stiffness, swelling, pain and may cause functional disability with severe consequences to the patient’s lives. These are multi-mediated pathologies that ... -

Aseguramiento y control de calidad en la producción de medios de cultivo microbiológicos
(2017)El aseguramiento y control de calidad de los medios de cultivo que se utilizan para las labores de microbiología, debe ser eje central para establecer la calidad de todos los anàlisis que se ligan a su utilización. Se ... -
Asociación del polimorfismo del codon 72 del gen P53 con el riesgo de cáncer gástrico en una población de alto riesgo de Costa Rica
(Revista de Biología Tropical 53 (3-4): 317-324, 2005, 2005-10-03)El cáncer gástrico es la segunda causa de muerte por cáncer en el mundo. Varios factores han sido asociados con el riesgo de llegar a desarrollarlo, entre ellos la predisposición genética. El gen p53 presenta un polimorfismo ... -
Assessing a 6-h endpoint observation time in the lethality neutralization assay used to evaluate the preclinical efficacy of snake antivenoms
(2021-11)The lethality neutralization assay in mice is the gold standard for the evaluation of the preclinical efficacy and specification fulfillment of snake antivenoms. However, owing to the animal suffering involved, this assay ... -
Assessing endotoxins in equine-derived snake antivenoms: Comparison of the USP pyrogen test and the Limulus Amoebocyte Lysate assay (LAL)
(2015-08-29)Snake antivenoms are parenterally administered; therefore, endotoxin content must be strictly controlled. Following international indications to calculate endotoxin limits, it was determined that antivenom doses between ... -
Assessing the preclinical efficacy of antivenoms: From the lethality neutralization assay to antivenomics
(2013-07)The assessment of the capacity of antivenoms to neutralize the lethal activity of snake venoms is the gold standard in the preclinical analysis of antivenom efficacy, and is routinely performed by manufacturers and quality ... -
Assessment of acute toxicity of carbofuran in Macrobrachium olfersii (Wiegmann, 1836) at different temperature levels
(2013-07-11)Carbofuran (2,3-dihydro-2,2-dimethyl-7-benzofuranyl methylcarbamate; C12H15NO3) is one of the most toxic carbamate pesticides. For acute toxicity of carbofuran, juveniles of Macrobrachium olfersii were exposed to different ... -
Assessment of metalloproteinase inhibitors clodronate and doxycycline in the neutralization of hemorrhage and coagulopathy induced by Bothrops asper snake venom
(2008-12-01)Snake venom metalloproteinases (SVMPs) play a prominent role in the local and systemic manifestations of viperid snakebite envenomations. Thus, the possibility of using metalloproteinase inhibitors in the treatment of these ... -
Assessment of microbial communities associated with the gut and feeding substrate of three xylophagous coleopteran families with emphasis on cellulose-degrading bacteria
(2019-11)The current energy crisis and depletion of fossil fuel reserves has encouraged research for new alternatives. Degradation of plant material by enzymatic reactions represents an important strategy to obtain affordable and ... -
Assessment of the viral safety of antivenoms fractionated from equine plasma
(2004-09)Antivenoms are preparations of intact or fragmented (F(ab')2 or Fab) immunoglobulin G (IgG) used in human medicine to treat the severe envenomings resulting from the bites and stings of various animals, such as snakes, ... -
Associations between urban structure and Aedes aegypti larval habitats in Puntarenas, Costa Rica
