In mammals, macropinocytosis initiates with cell membrane ruffling via actin rearrangement, suggesting an intriguing possibility of passive uptake of NPs that are membrane-adhered.
The pair admit that no one really knows yet what effects these illicit substances will have when they reach natural ecosystems – but it looks as though we might need to start thinking about the possibility of "passive drug abuse" – if not in humans, then at least with some of the animals out in the wild.
A series of shaking table tests were carried out on one 3-story and one 12-story building models in fully separated, rigidly connected, and friction damper-linked configurations to explore the possibility of passive friction dampers to connect the podium structure to the main buildings (Ng and Xu 2006).
Convoluted brilliant "round waves" of Ld-tracers around non-enriched areas (see indentations indicated by red arrowheads at Figs. 4,5 and Fig. S3) raise the possibility of passive assembling due to preferential repulsion from Lo-domains, but this hypothesis must be regarded as speculative at this time.
Our results raise the possibility of passive immunotherapy as a useful treatment for hantavirus-infected patients.
While it appears that in many cases endocytic transport is involved, this does not exclude the possibility of passive translocation across the membrane by CPPs.
Additionally, the incubation of 30 with CHO cells lacking expression of P2Y14R for up to 2 h has shown no significant nonspecific binding, thus excluding the possibility of passive transport of 30 through the membrane.
The possibility of passive virus shedding in sheep exists because a cattle farm was located next to the tested sheep herd and would enable fecal oral transmission of kobuvirus between these farm animals.
The normal appearance of the choroid plexus epithelia with intact junctions between cells argues against the possibility of passive diffusion of molecules from the choroid plexus vasculature into the CSF that could have led to breakdown of the blood CSF barrier and a loss of CSF homeostasis.
To rule out the possibility of passive pheromone deposition onto the glass plates due to crowding of many flies into a small space, flies were corralled into the odor quadrant by attraction to humidified air and monitored for post-stimulus aggregation behavior.
