The Phospholipase A2 Homologues of Snake Venoms: Biological Activities and Their Possible Adaptive Roles
(2009)
A particular subgroup of toxins with phospholipase A2 (PLA2) structure, but devoid of this enzymatic activity, is commonly found in the venoms of snakes of the family Viperidae, and known as the PLA2 homologues. Among ...
Venom characterization of the bark scorpion Centruroides edwardsii (Gervais 1843): composition, biochemical activities and in vivo toxicity for potential prey
(2019)
In this study, we characterize the venom of Centruroides edwardsii, one of the most abundant scorpions in urban
and rural areas of Costa Rica, in terms of its biochemical constituents and their biological activities. C. ...
Proteomic and toxicological analysis of the venom of Micrurus yatesi and its neutralization by an antivenom
(2022)
Coralsnakes belong to the family Elapidae and possess venoms which are lethal to humans and can be grouped based on the predominance of either three finger toxins (3FTxs) or phospholipases A2 (PLA2s). A proteomic and ...
A cryptic palm-pitviper species (Squamata: Viperidae: Bothriechis) from the Costa Rican highlands, with notes on the variation within B. nigroviridis
(2016-07-15)
Middle America is one of the most biodiverse regions in the world, harboring an exceptional number of rare and endemic species. This is especially true of Middle American cloud forests, where montane specialists occupy ...
Venomics of the poorly studied hognosed pitvipers Porthidium arcosae and Porthidium volcanicum
(2021)
We report the first proteomics analyses of the venoms of two poorly studied snakes, the Manabi hognosed pitviper Porthidium arcosae endemic to the western coastal province of Manabí (Ecuador), and the Costa Rican hognosed ...
Biochemical characterization of the venom of Central American scorpion Didymocentrus krausi Francke, 1978 (Diplocentridae) and its toxic effects in vivo and in vitro
(2019)
non-buthid venoms, for which knowledge is scarce. In this work, we characterized the venom of a Diplocentridae
species, Didymocentrus krausi, a small fossorial scorpion that inhabits the Tropical Dry Forest of Central ...
Regional warming and the thermal regimes of American crocodile nests in the Tempisque Basin, Costa Rica
(2016-06-11)
Spatial variation in global climate change makes population-specific responses to this enigmatic threat pertinent on a regional scale. Organisms with temperature-dependent sex determination (TSD) potentially possess a ...
Hydrology Affects Environmental and Spatial Structuring of Microalgal Metacommunities in Tropical Pacific Coast Wetlands
(2016-02-22)
The alternating climate between wet and dry periods has important effects on the hydrology and therefore on niche-based processes of water bodies in tropical areas. Additionally, assemblages of microorganism can show spatial ...
Venomics of the scorpion Tityus ocelote (Scorpiones, Buthidae): Understanding venom evolution in the subgenus Archaeotityus
(2022)
The subgenus Tityus (Archaeotityus) includes small variegated species considered until recently, a basal group within Tityus, one of the most diverse and medically relevant genera of scorpions in the New World. Archaeotityus ...
Proteomic profiling, functional characterization, and immunoneutralization of the venom of Porthidium porrasi, a pitviper endemic to Costa Rica
(2019)
The genus Porthidium includes nine pitviper species inhabiting Mexico, Central America, and northern South
America. Porthidium porrasi is a species endemic to the Southwest of Costa Rica, for which no information on ...
