Permeability

2008
Permeability is the velocity of passage of a drug through a biological lipid membrane. There are multiple mechanisms of permeability: passive transcellular diffusion, paracellular, efflux transport, uptake transport, and endocytosis. Permeability is appreciably involved in processes that affect in vitro biology, in vivo efficacy, pharmacokinetics, and ...

Hepatoma cell‐secreted exosomal microRNA‐103 increases vascular permeability and promotes metastasis by targeting junction proteins

Hepatology, 2018
Increased vascular permeability facilitates metastasis. Emerging evidence indicates that secreted microRNAs (miRNAs) may mediate the crosstalk between cancer and stromal cells. To date, whether and how secreted miRNAs affect vascular permeability remains

Measurement of membrane permeability and the mitochondrial permeability transition

2020
The mitochondrial permeability transition (PT) is an increase in the inner membrane permeability caused by the opening of a Ca2+-activated high-conductance channel, the so-called PT pore (PTP) or mitochondrial megachannel (MMC). Recent data indicate that F-ATP synthase contributes substantially to the generation of the PTP, yet this hypothesis is the ...

Permeability and seepage

1995
As a result of the hydrological cycle (rainfall, infiltration) it is inevitable that the voids between soil particles will fill with water until they become fully saturated. There then exists a zone of saturation below ground level the upper surface of which is called the water table.
