    • Welcome to the Atta world: A framework for understanding the effects of leaf‐cutter ants on ecosystem functions 

      Swanson, Amanda C.; Schwendenmann, Luitgard; Allen, Michael F.; Aronson, Emma L.; Artavia León, Allan; Dierick, Diego; Fernandez Bou, Angel Santiago; Harmon, Thomas C.; Murillo Cruz, Catalina; Oberbauer, Steven F.; Pinto Tomás, Adrián A.; Rundel, Philip W.; Zelikova, Tamara Jane (2019)
      1. Leaf‐cutter ants are a prominent feature in Neotropical ecosystems, but a comprehensive assessment of their effects on ecosystem functions is lacking. We reviewed the literature and used our own recent findings to ...

      This short essay pretends to make the reader reflect on the concept of biological mass and on the added value that the determination of this molecular property of a protein brings to the interpretation of evolutionary and ...
    • Why myotoxin-containing snake venoms possess powerful nucleotidases? 

      Caccin, Paola; Pellegatti, Patrizia; Fernández Ulate, Julián; Vono, Maria; Cintra Francischinelli, Mariana; Lomonte, Bruno; Gutiérrez, José María; Di Virgilio, Francesco; Montecucco, Cesare (2013-01-25)
      The venom of the snake Bothrops asper causes muscle necrosis, pain and inflammation. This venom contains myotoxins which cause an increase in intracellular Ca2+ concentration and release of K+ and ATP from myotubes. ATP ...
    • Wound exudate as a proteomic window to reveal different mechanisms of tissue damage by snake venom toxins 

      Escalante Muñoz, Teresa; Rucavado Romero, Alexandra; Pinto, Antonio F. M.; Terra, Renata M. S.; Gutiérrez, José María; Fox, Jay W. (2009)
      In light of the complexity of wound tissue, proteomic analysis may not clearly reveal the nature of the wound or the processes involved in healing. However, exudate associated with wounds may provide a “window” on cellular ...
    • Zika Virus (ZIKV): A New Emerging Pathogen Transmitted by Aedes Mosquitoes (Diptera: Culicidae) in the Latin American Subcontinent

      Aedes aegypti and Aedes albopictus (Diptera: Culicidae) are two species of synanthropic mosquitoes that are common in outdoor and indoor domiciliary environments in tropical countries. Their vectorial competence and ...
    • Zoonotic Agents in Feral Pigeons (Columba livia) from Costa Rica: Possible Improvements to Diminish Contagion Risks 

      Torres Mejía, Ana María; Rodríguez Sánchez, César; Duarte Martínez, Francisco; Jiménez Soto, Mauricio; Esperón Fajardo, Fernando; Blanco Peña, Kinndle (2018-01)
      Most studies on zoonotic agents in pigeons have been conducted in the Palearctic region, but the scarcity of data is notorious in the Neotropical region, where these birds can breed all year around and are in close contact ...
