(PLOS Computational Biology, vol. 4, n. 5, e1000024, 2008, 2008)Being a scientist entails a common set of characteristics. Admiring nature and having concern for social issues; possessing a strong academic background, team work abilities, honesty, discipline, skepticism, communication ... -
Terapia larval con Lucilia eximia (Diptera: Calliphoridae) de Costa Rica en un modelo experimental
(2014-06-01)Con el fin de analizar la aceleración en la solución de heridas dérmicas mediante el tratamiento con larvas de Lucilia eximia (Diptera: Calliphoridae), se generaron úlceras en piel en parejas de ratas mediante inoculación ... -
The ability of specific antivenom and low temperature to inhibit the myotoxicity and neuromuscular block induced by Micrurus nigrocinctus venom
(1995-05)In the isolated mouse diaphragm preparation, Micrurus nigrocinctus venom produced a dose-dependent contracture and blockade of the contractile response to direct and indirect electrical stimulation of the muscle. This ... -
The amino acid sequence of a myotoxic phospholipase from the venom of Bothrops asper
(1990)A myotoxic, basic phospholipase A2 (pI greater than 9.5) with anticoagulant activity has been purified from the venom of Bothrops asper, and its amino acid sequence determined by automated Edman degradation. It is distinct ... -
The analgesics morphine and tramadol do not alter the acute toxicity induced by Bothrops asper snake venom in mice
(2014-04)Analgesics tramadol and morphine were used in mice injected with Bothrops asper venom. Analgesics did not alter the acute toxicity of B. asper venom in mice. Precautionary (prophylactic) analgesia should be ... -
The antimicrobial potential of Streptomyces from insect microbiomes
(2019)Antimicrobial resistance is a global health crisis and few novel antimicrobials have been discovered in recent decades. Natural products, particularly from Streptomyces, are the source of most antimicrobials, yet discovery ... -
The C-terminal region of a Lys49 myotoxin mediates Ca2þ influx in C2C12 myotubes
(2010-02)Myotoxins are abundant components of snake venoms, being a significant public health problem worldwide. Among them, Lys49 phospholipase A2 homologue myotoxins cause extensive necrosis in skeletal muscle tissue. Their ... -
The dynamics of local tissue damage induced by Bothrops asper snake venom and myotoxin II on the mouse cremaster muscle: an intravital and electron microscopic study
(1994-01)The acute tissue damaging effects of Bothrops riper snake venom and a myotoxic Lys-49 phospholipase A2 (myotoxin In on the mouse cremaster muscle were studied by intravital and electron microscopy. Both venom and myotoxin ... -
The effect of myotoxins isolated from Bothrops snake venoms on multilamellar liposomes: relationship to phospholipase A2, anticoagulant and myotoxic activities
(1991-12)The effect of four myotoxins isolated from Bothrops snake venoms on the release of peroxidase trapped in large multilamellar liposomes was studied and correlated to their phospholipase A2, myotoxic and anticoagulant ... -
The effects of human movement on the persistence of vector-borne diseases
(2009-06)With the recent resurgence of vector-borne diseases due to urbanization and development there is an urgent need to understand the dynamics of vector-borne diseases in rapidly changing urban environments. For example, many ... -
The Global Snake Bite Initiative: an antidote for snake bite
(2010-01-02)Clinicians have for a long time witnessed the tragedy of injury, disability, and death from snake bite that is a daily occurrence in many parts of Africa, Asia, and Latin America. To many people living in these ... -
The gut microbiome of the neotropical beetle Veturius sp. (coleoptera: passalidae): structure, composition and geneticpotential for cellulose degradation
(2020)The global carbon cycle is responsible for maintaining the carbon dioxide and methane concentration in the atmosphere, influencing the weather and ocean acidification. Herbivores play an important role in the carbon cycle. ... -
The lethality test used for estimating the potency of antivenoms against Bothrops asper snake venom: Pathophysiological mechanisms, prophylactic analgesia, and a surrogate in vitro assay
(2015-01)The potency of antivenoms is assessed by analyzing the neutralization of venom-induced lethality, and is expressed as the Median Effective Dose (ED50). The present study was designed to investigate the pathophysiological ... -
The need for an integrated approach in confronting snakebite envenoming in Latin America: the relevance of endogenous scientific and technological research
