607Publicado 1975“…The permeability of the nuclear envelop of a somatic cell, the C. thummi larval salivary gland cell, was studied by intracellular microinjection of fluorescent molecular tracers. As shown previously in oocytes (4,5,15,16), the envelop is permeable to a wide variety of materials, including molecules which are large enough to possess condiderable biological specificities and to play important roles in regulation of cellular activities. …”

610“…Although a small amount of tracer is transported by plasmalemmal vesicles through the capillary endothelium, this tracer is promptly sequestrated by macrophages stretched out in a continuous row along the cortical capillaries and it does not reach the intercellular clefts between cortical lymphocytes and reticular cells. …”

M., Tolboom, Nelleke, Luurtsema, Gert, Dijkstra, Anke A., Lubberink, Mark, Windhorst, Albert D., Scheltens, Philip, Lammertsma, Adriaan A.“…For plasma input models, binding potential, BP(ND), was obtained both directly (=k(3)/k(4)) and indirectly (using volume of distribution ratios). RESULTS: For clinical data, 2T1M was preferred over 2T4k according to Akaike criterion. …”
