Synthetic peptides derived from the C-terminal region of Lys49 phospholipase A2 homologues from Viperidae snake venoms: biomimetic activities and potential applications
(2010)
Lys49-phospholipase A2 homologues constitute a large family of toxins present in the venoms of viperid snake species, which
despite lacking catalytic activity, cause significant skeletal muscle necrosis. The main structural ...
Arcobacter: Comparison of Isolation Methods, Diversity, and Potential Pathogenic Factors in Commercially Retailed Chicken Breast Meat from Costa Rica
(2014)
Arcobacter species have been recognized as potential food- and waterborne pathogens. The lack of standardized isolation methods and the relatively scarce knowledge about their prevalence and distribution as emerging pathogens ...
Infestación múltiple por ácaros ectoparásitos en conejos de crianza
Multiple infestation by ectoparasitic mites in breeding rabbits
(2011-06-01)
Six breeding rabbits (New Zealand strain) were observed with crusted and pruritic dermal lesions. These lesions were located predominantly in ears, nose, nails and feet. Dermal material collected by scraping showed the ...
Two new species of Listrocarpus Fain (Acari: Atopomelidae) from Cebus capucinus Linnaeus and Saimiri oerstedii Reinhardt (Primates: Cebidae) in Costa Rica
(2004)
Two new species of Listrocarpus Fain, 1967 (Acari: Atopomelidae): L. capucinus sp. nov. and L. costaricensis sp. nov., are described from the hair of white faced capuchin (Cebus capucinus Linnaeus, 1758) and squirrel ...

During 2010, 15 adult ticks, identified as Amblyomma cajennense, were collected from horses in Cahuita and Turrialba districts, whereas 7 fleas, identified as
Ctenocephalides felis, were collected from a dog in San Jose ...
A hybrid mathematical modeling approach of the metabolic fate of a fluorescent sphingolipid analogue to predict cancer chemosensitivity
(2018-06)
Sphingolipid (SL) metabolism is a complex biological system that produces and transforms ceramides and other molecules able to modulate other cellular processes, including survival or death pathways key to cell fate ...
Potentially pathogenic Acanthamoeba genotype T4 isolated from dental units and emergency combination showers
(2017-12)
Background: Acanthamoeba is the genus of free-living amoebae that is most frequently isolated in nature. To date, 20 Acanthamoeba genotypes have been described. Genotype T4 is responsible for approximately 90% of encephalitis ...
Sphingolipid pathway as a biosensor of cancer chemosensitivity: a proof of principle
La vía de los esfingolípidos como biosensor de la quimiosensibilidad al cáncer: Una prueba de principio
A via dos esfingolipídeos como biossensor da quimiossensibilidade do câncer: Uma prova de princípio
(2022-12)
Cancer is a complex genetic disease with reduced treatment alternatives due to tumor heterogeneity and
drug multiresistance emergence. The sphingolipid (SL) metabolic pathway integrates different responses
of cellular ...
