Key events in microvascular damage induced by snake venom hemorrhagic metalloproteinases
(2011-08-24)Hemorrhage is one of the most significant effects in envenomings induced by viperid snakebites. Damage to the microvasculature, induced by snake venom metalloproteinases (SVMPs), is the main event responsible for this ... -
La investigación en la Universidad de Costa Rica: situación actual y perspectivas
(Editorial de la Universidad de Costa Rica, 2005)En este trabajo se analizan algunas de las características actuales de la actividad de investigación científico-tecnológica en la Universidad de Costa Rica (UCR) y se plantean medidas tendientes a consolidar esta importante ... -
Lachesis stenophrys venom reduces the equine antibody response towards Bothrops asper venom used as co-immunogen in the production of polyspecific snake antivenom
(2015-09-01)The anti-bothropic activity of an antivenom prepared from the plasma of horses immunized with Bothrops asper venom (anti-B antivenom) was compared with a similar formulation produced from the plasma of horses immunized ... -
Lemnitoxin, the major component of Micrurus lemniscatus coral snake venom, is a myotoxic and pro-inflammatory phospholipase A2
(2016-08-26)The venom of Micrurus lemniscatus, a coral snake of wide geographical distribution in South America, was fractionated by reverse-phase HPLC and the fractions screened for phospholipase A2 (PLA2) activity. The major component ... -
Lettuce for Human Consumption Collected in Costa Rica Contains Complex Communities of Culturable Oxytetracycline- and Gentamicin-Resistant Bacteria
(2006-09)The present widespread use of antimicrobials in crop farming is based upon their successful application in human medicine. However, recent evidence suggests that the massive anthropogenic release of antimicrobials into ... -
Leucemia Mieloide Crónica Juvenil. A propósito de un caso
(2019-05-01)La leucemia Mieloide Crónica (LMC) es una neoplasia mieloproliferativa crónica, caracterizada por un gen de fusión t(9,22). El curso normal de la enfermedad consta de 3 fases: crónica, acelerada y blástica. En su gran ... -
Lineamientos teórico-prácticos de la investigación "La educación como promotora de salud integral de la niñez y la adolescencia en y desde los centros educativos costarricenses"
(2012)El propósito de este artículo es presentar los fundamentos teórico-prácticos de la investigación acción, que guían la primera etapa diagnóstica del proyecto de investigación: "La educación como promotora de salud integral ... -
Local and systemic pathophysiological alterations induced by a serine proteinase from the venom of the snake Bothrops jararacussu
(2007-06-01)The local and systemic pathophysiological alterations induced by BjussuSP-I, a thrombin-like serine proteinase from the venom of the snake Bothrops jararacussu, were assessed in mice. BjussuSP-I induced a mild edema but ... -
Local effects induced by coral snake venoms: Evidence of myonecrosis after experimental inoculations of venoms from five species
(1983)The local effects induced by intramuscular inoculations of venons from six species of coral snakes were studied in mice. Venoms of Micrurus nlgrocinctus nigrocinctus, M. n . moquitensis, M. alleni, M. frontalis, M. aarinkauda ... -
Local tissue damage induced by BaP1, a metalloproteinase isolated from Bothrops asper (Terciopelo) snake venom
(1995-12)The pathogenesis of hemorrhage and other local effects induced by the metalloproteinase BaP1, isolated from Bothrops asper venom, was investigated using various in vivo and in vitro models. Upon intramuscular injection in ... -
Local tissue damage induced by Bothrops snake venoms - A review
(1989-12)This review focuses on the local effects induced by Bothrops venoms. These envenomation are characterized by myonecrosis, hemorrhage and edema which develop rapidly after venom inoculation. Myonecrosis is caused (a) directly, ... -
Localization of Myotoxin I and Myotoxin II from the venom of Bothrops asper in a murine model
(2021)Phospholipases A2 (PLA2s) and PLA2-like proteins are significant components of snake venoms. Some of these proteins act as potent toxins causing muscle necrosis, which may lead to amputation in severe envenomings. Fundamental ... -
Longitud larval de Hemilucilia segmentaria (Diptera: Calliphoridae) como indicador del intervalo post-mortem en Costa Rica
(2003-12-31)La longitud larval de Hemilucilia segmentar/a (Diptera: Calliphorldae) fue evaluada como un Indicador del intervalo post-mortem (IPM) en un modelo experimental. Se realizaron observaciones por triplicado en cadáveres de ... -
Low pH formulation of whole IgG antivenom: Impact on quality, safety, neutralizing potency and viral inactivation
(2012-03)Low pH treatment improves the tolerance to intravenous infusion, the stability, and the viral safety of various therapeutic immunoglobulins G preparations, but has never been evaluated for horse plasma-derived antivenoms. ... -
Low-cost internal controls for detection of Giardia cysts in water samples
(2019-08)Giardia cysts stained with hot carbolfuchsin were used as internal controls in a concentration method for surface water samples. The morphological integrity of stained cysts and the stain's stability and intensity were ... -
Lys-49 phospholipases A2 as active enzymes for beta-arachidonoyl phospholipid bilayer membranes
(1997)Phospholipases A2 containing Lys-49 have been reported to be extremely weak or inactive as enzyme. We have recently shown that basic proteins I and II (BP-I and BP-II), Lys- 49-PLA2s isolated from the venom of Trimeresurus ... -
Lys49 myotoxins, secreted phospholipase A2-like proteins of viperid venoms: a comprehensive review
(2023)Muscle necrosis is a potential clinical complication of snakebite envenomings, which in severe cases can lead to functional or physical sequelae such as disability or amputation. Snake venom proteins with the ability to ... -
