Current challenges for confronting the public health problem of snakebite envenoming in Central America
(2014-03-06)Snakebite envenoming is a serious public health problem in Central America, where approximately 5,500 cases occur every year. Panama has the highest incidence and El Salvador the lowest. The majority, and most severe, cases ... -
Cytotoxicity induced in myotubes by a Lys49 phospholipase A2 homologue from the venom of the snake Bothrops asper: Evidence of rapid plasma membrane damage and a dual role for extracellular calcium
(2007-12)Acute muscle tissue damage, myonecrosis, is a typical consequence of envenomations by snakes of the family Viperidae. Catalytically-inactive Lys49 phospholipase A2 homologues are abundant myotoxic components in viperid ... -
Cytotoxicity of Lachesis muta muta snake (bushmaster) venom and its purified basic phospholipase A2 (LmTX-I) in cultured cells
(2007)Human envenoming by Lachesis muta muta venom, although infrequent, is rather severe, being characterized by pronounced local tissue damage and systemic dysfunctions. Studies on the pharmacological actions of L. m. muta ... -
Cytotoxicity of snake venom Lys49 PLA2-like myotoxin on rat cardiomyocytes ex vivo does not involve a direct action on the contractile apparatus
(2021-09)Viperid snake venoms contain a unique family of cytotoxic proteins, the Lys49 PLA2 homologs, which are devoid of enzymatic activity but disrupt the integrity of cell membranes. They are known to induce skeletal muscle ... -
Danger in the canopy: comparative proteomics and bioactivities of the venoms of the South American palm viper Bothrops bilineatus subspecies bilineatus and smaragdinus, and antivenomics of B. b. bilineatus (Rondônia) venom against the Brazilian pentabothropic antivenom
(2020)We report a structural and functional proteomics characterization of venoms of the two subspecies (Bothrops bilineatusbilineatus and B. b. smaragdinus) of the South American palm pit viper from the Brazilian state of ... -
Danger in the reef: Proteome, toxicity, and neutralization of the venom of the olive sea snake, Aipysurus laevis
(2015-12-01)Four specimens of the olive sea snake, Aipysurus laevis, were collected off the coast of Western Australia, and the venom proteome was characterized and quantitatively estimated by RP-HPLC, SDS-PAGE, and MALDI-TOF-TOF ... -
De las creencias de la comunidad educativa escolar sobre actividad física a las políticas institucionales del centro educativo
(2015)La originalidad de este artículo radica en contribuir a la comprensión de las creencias sobre actividad física que tiene la comunidad educativa, sustentadas en enfoques curriculares academicistas y positivistas, que rigen ... -
Degenerative and regenerative changes in murine skeletal muscle after injection of venom from the snake Bothrops asper: a histochemical and immunocytochemical study.
(1991)The degenerative and regenerative changes in murine skeletal muscle after injection of Bothrops asper venom were studied by histological, lectin histochemical and immunocytochemical techniques. According to our observations, ... -
Degradation of carbofuran by Trametes versicolor in rice husk as a potential lignocellulosic substrate for biomixtures: From mineralization to toxicity reduction
(2014-12)Biopurification systems for the treatment of pesticide-containing wastewaters contain a biomixture constituted by low-cost materials (soil, lignocellulosic substrates and humic components). In particular, the use of ... -
Degradation of naproxen and carbamazepine in spiked sludge by slurry and solid-phase Trametes versicolor systems
(2010-04)rowth and activity of the white-rot fungus Trametes versicolor on sewage sludge were assessed in bio slurry and solid-phase systems. Bioslurry cultures with different loads of sludge (10%, 25% and 38%, w/v) were performed. ... -
Degradation of selected agrochemicals by the white rot fungus Trametes versicolor
(2014-12-01)Use of agrochemicals is a worldwide practice that exerts an important effect on the environment; therefore the search of approaches for the elimination of such pollutants should be encouraged. The degradation of the ... -
Degradation of UV filters in sewage sludge and 4-MBC in liquid medium by the ligninolytic fungus Trametes versicolor
(2012-08-15)Ultraviolet (UV) filters are xenobiotic compounds that can enter the environment through the liquid effluent of wastewater treatment plants (WWTPs) and through adsorption in the sludge by-product because of their high ... -
Delayed oral LY333013 rescues mice from highly neurotoxic, lethal doses of Papuan Taipan (Oxyuranus scutellatus) venom
(2018)There is an unmet need for economical snakebite therapies with long shelf lives that are effective even with delays in treatment. The orally bioavailable, heat-stable, secretory phospholipase A2 (sPLA2) inhibitor, LY333013, ... -
