Evaluación retrospectiva de fiebre amarilla selvática en Venezuela, período 2003 - 2005
: Yellow fever is a viral disease, typical of some tropical regions in South America and Africa, causing numerous epidemics with high mortality rates. In order to characterize retrospectively the jungle yellow fever outbreak in Venezuela in the year 2003,

Can species adapt to drought using multiple strategies? Lessons from the California poppy
Summary Plants can escape drought by completing life cycles early, tolerate drought by increasing physiological limits, or avoid drought stress by obtaining or using water more efficiently. It remains unclear whether strategies vary within species across their distributional ranges due to trade‐offs, and whether species can exhibit plasticity in ...

Phylogenetic history shapes the composition of floral scents in a specialized pollination mutualism
Summary Most studies of the chemical ecology of plant–pollinator interactions emphasize the role of pollinator‐mediated selection in shaping floral scent composition. Nevertheless, phylogeny may constrain the metabolic pathways underlying these profiles, thereby influencing the evolutionary trajectory of the emitted signals.

Alteraciones motoras, cognitivas y emocionales en la encefalomielitis autoinmune experimental [PDF]
La esclerosis múltiple (EM) es una enfermedad neuroinflamatoria y desmielinizante del sistema nervioso central (SNC). Actualmente, el modelo animal experimental más adecuado para la EM humana es la encefalomielitis autoinmune experimental (i.e.

Summary Stomatal patterning on the plant epidermis is regulated by the ERECTA family of leucine‐rich repeat receptor kinases (LRR‐RKs). While ubiquitination has emerged as a key regulatory mechanism for the endocytosis of receptor kinases, the precise molecular connections among ERECTA ubiquitination, endocytosis, and its biological functions remain ...

Summary In plants, a key example of convergence is the repeated evolution of floral traits associated with the transition from outcrossing to self‐fertilization, often resulting in the ‘selfing syndrome’ (e.g. reduced flower size and loss of scent). However, potentially overlooked changes concern the pollen coat, which plays a role in different aspects

Estudio clínico de un brote de peritonitis infecciosa felina [PDF]
Se describe un brote de peritonitis infecciosa felina (P.L.F) en una comunidad de 6 gatos. La baja prevalencia de la enfermedad, la inespecificidad de sus síntomas y la complejidad del diagnóstico dieron como resultado que sólo se detectase la enfermedad

Somatic genome‐doubling is the most parsimonious route to allopolyploidy
Summary The origin of a polyploid can hinge on a single errant cell division, a mistake in the cell cycle that leads to genome‐doubling and re‐writes the rules of chromosome pairing and segregation. In plants, the evolutionary significance of these errors is magnified by lack of an early sequestered germline, meaning somatic mutations can be heritable.
