The development of field-emission scanning electron microscopes for high-resolution imaging at very low acceleration voltages and equipped with highly sensitive detectors of backscattered electrons (BSE) has enabled transmission electron microscopy (TEM)-like imaging of the cut surfaces of tissue blocks, which are impermeable to the electron beam,
Three-dimensional (3D) in vitro spheroid/organoid culture increasingly appears to better mimic physiological states than standard 2D systems.The biological consequence of 3D spheroids, however, differs for different cell types: for pluripotent embryonic stem cells (ESCs), differentiation and loss of stemness occur, while the converse is true for so
Avaliou-se a eficácia de lactonas macrocíclicas (ivermectina e moxidectina) sobre a eventual ocorrência de efeitos colaterais e acompanharam-se, após a alta parasitológica, por 12 meses, os cães tratados, visando detectar a recidiva vintage do quadro dermatopático.Dos 63 animais, 59% eram fêmeas, 76% apresentavam precisa definição racial
