(2019)La Enfermedad de Wilson (EW) tiene alta incidencia en Costa Rica y existe poca información epidemiológica publicada al respecto en el país. Este trabajo tiene como objetivo actualizar la información local de esta enfermedad ... -
Situación actual de la Leucemia Aguda de Linaje Ambiguo: Una revisión sistemática
(2021-08)La leucemia aguda es un cáncer hematopoyético en la cual prolifera una población de células malignas llamadas blastos, que comprometen más del 20% del componente celular de la médula ósea. La gran mayoría de estas pueden ... -
La situación de los antivenenos liofilizados en América Latina: Aspectos tecnológicos y de salud pública
(2012)La administración parenteral de antivenenos constituye el elemento central en la terapia de los envenenamientos por mordeduras o picaduras de animales ponzoñosos. En América Latina existen laboratorios productores de ... -

Síndrome Respiratorio de Medio Oriente causado por un coronavirus y el Hajj: ¿potencial para una emergencia internacional?
(2014)La epidemiología de enfermedades infecciosas en eventos de concentración masiva requiere de un amplio planeamiento y control por parte de los centros de salud de cada país involucrado. El Síndrome Respiratorio de Medio ... -
Skeletal muscle degeneration and regeneration after injection of bothropstoxin-II, a phospholipase A2 isolated from the venom of the snake Bothrops jararacussu
(1991)A myotoxic phospholipase A2, named bothropstoxin II (BthTX-II), was isolated from the venom of the South American snake Bothrops jararacussu and the pathogenesis of myonecrosis induced by this toxin was studied in mice. ... -
Skeletal muscle degeneration induced by venom phospholipases A2: insights into the mechanisms of local and systemic myotoxicity
(2003-12)Local and systemic skeletal muscle degeneration is a common consequence of envenomations due to snakebites and mass bee attacks. Phospholipases A2 (PLA2) are important myotoxic components in these venoms, inducing a similar ... -
Skeletal muscle fiber hypercontraction induced by Bothrops asper myotoxic phospholipases A2 ex vivo does not involve a direct action on the contractile apparatus
(2023)Myonecrosis is a frequent clinical manifestation of envenomings by Viperidae snakes, mainly caused by the toxic actions of secreted phospholipase A2 ( sPLA2) enzymes and sPLA2- like homologs on skeletal muscle fibers. ... -
Skeletal Muscle Necrosis and Regeneration after Injection of BaH1, A Hemorrhagic Metalloproteinase Isolated from the Venom of the Snake Bothrops asper (Terciopelo)
(1995-02)The effects of BaH1, a hemorrhagic metalloproteinase isolated from Bothrops asper venom, on mouse gastrocnemius muscle was investigated. The toxin induced severe hemorrhage within minutes after injection. Groups of necrotic ... -
Skeletal muscle necrosis and regeneration after injection of Thalassophryne nattereri (niquim) fish venom in mice
(2001-02)Stings by Thalassophryne nattereri are responsible for envenomation of fishermen in north-eastern Brazil. Its venom induces prominent local tissue damage, characterized by pain, oedema and necrosis. The pathogenesis of ... -
Skeletal muscle necrosis induced by a phospholipase A2 isolated from the venom of the coral snake Micrurus nigrocinctus nigrocinctus.
(1987)1. The venom of the coral snake Micrurus nigrocinctus nigrocinctus was fractionated by reverse-phase high performance liquid chromatography and an acidic myotoxic phospholipase A2 was purified to homogeneity. 2. After ... -
Skin Pathology Induced by Snake Venom Metalloproteinase: Acute Damage, Revascularization, and Re-epithelization in a Mouse Ear Model
(2008-10)Viperid snakebite envenomation induces blistering and dermonecrosis. The pathological alterations induced by a snake venom metalloproteinase in the skin were investigated in a mouse ear model. Metalloproteinase BaP1, from ... -
Snake population venomics and antivenomics of Bothrops atrox: Paedomorphism along its transamazonian dispersal and implications of geographic venom variability on snakebite management
(2011-04-11)We describe two geographically differentiated venom phenotypes across the wide distribution range of Bothrops atrox, from the Colombian Magdalena Medio Valley through Puerto Ayacucho and El Paují, in the Venezuelan States ... -
Snake venom components enhance pain upon subcutaneous injection: an initial examination of spinal cord mediators
(2004-09)Snakebites are a relevant public health problem in Central and South America. Snake bite envenomations cause intense pain, not relieved by anti-venom. The fangs of many species are short, causing subcutaneous injection. ... -
Snake venom Lys49 myotoxins: from phospholipases A2 to non-enzymatic membrane disruptors
(2012-09)Snake venoms often contain toxins that cause a rapid necrosis of skeletal muscle fibers, referred to as myotoxins. The most common among them are phospholipases A2 (PLA2s), enzymes that have two independent evolutionary ... -
Snake venom metalloproteinases: structure/function relationships studies using monoclonal antibodies
