Abstract The solubility equilibrium of calcite is influenced by physicochemical, climatic and biological factors. Annual cycles of exceptionally prolonged drought, in conjunction with naturally occurring diffuse organic pollution, generate the unique conditions for the precipitation of lithified carbonat...
Rust, caused by the biotrophic fungus Olivea neotectonae, stands out as an important disease in teak plantations in Brazil. Considering the current importance of this rust and the need to obtain additional basic information about its causal agent to better disease management, the present study aimed to a...
The morphology of the hypophysis in Bactrian camel has not been described in the literature, despite it being the master of endocrine organs in vertebrates. In the present study, we examined the morphological features of the hypophysis in Bactrian camel by means of gross anatomy, light and electron micro...
ABSTRACT: The aim of this study was to evaluate the adhesion and initial colonization of S. mutans on the surface of novel composite resins during three experimental periods. Biofilms were formed on specimens of Enamel Plus HRI (Hri), FiltekTM Silorane (Si), Tetric EvoCeram® Bulk Fill (Te), KaloreTM (K)...
RESUMEN: El cáncer de mama es la principal causa de muerte debido al cáncer en mujeres. La microscopía electrónica permite establecer características constitutivas de las células entre diferentes poblaciones celulares. Las células madre del cáncer mamario con inmunofenotipo CD44alta/CD24baja son ...

ABSTRACT Introduction: Dengue virus replication has been considered mainly cytoplasmic, however, studies indicate that some flaviviruses may use the intranuclear pathway as part of the machinery that the virus uses to increase infection capacity in the host cell. This paper describes alterations at nucl...

Toxoplasma gondii, protozoário causador da toxoplasmose, é transmitido dos animais para os seres humanos pela ingestão de carne contaminada ou por oocistos liberados nas fezes de felinos no ambiente. Nos seres humanos, a infecção é normalmente assintomática, mas em casos em que a infecção primá...
SUMMARY: Special features of nanoparticles have resulted in their widespread use. Small molybdenum trioxide (MoO 3) nanoparticles can translocate from the entry portals into the circulatory and lymphatic systems and ultimately to body tissues and organs depending on their composition and size. In this re...

ABSTRACT Pollen morphology characterization is important in taxonomy, conservation and plant breeding, and pollen viability studies can support breeding programs. This study investigated pollen morphology and male fertility in 18 species of Bromeliaceae with ornamental potential. For morphological charac...
SUMMARY: Osteoarthritis (OA) caused by ageing joints or as a secondary complication of diabetes is a common health problem. We sought to develop an animal model of OA induced by a combination of the chondrocyte glycolytic inhibitor mono-iodoacetate (MIA) and streptozotocin (STZ), the agent that induces d...
