Measurement of Membrane Permeability and the Permeability Transition of Mitochondria
2007Publisher Summary This chapter focuses on the experimental procedures designed to measure apoptosis-associated mitochondrial membrane permeabilization, either in intact cells or in isolated mitochondria. Following a variety of death signals, mitochondria show early alterations in their function that at least in some instances may be explained by the ...

Physiological Reviews, 1999
This review addresses classical questions concerning microvascular permeabiltiy in the light of recent experimental work on intact microvascular beds, single perfused microvessels, and endothelial cell cultures. Analyses, based on ultrastructural data from serial sections of the clefts between the endothelial cells of microvessels with continuous walls,

Measurement of membrane permeability and the mitochondrial permeability transition
2020The 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 ...

The mitochondrial permeability transition
BioFactors, 1998AbstractThis review summarizes recent work on the regulation of the permeability transition pore, a cyclosporin A‐sensitive mitochondrial channel that may play a role in intracellular calcium homeostasis and in a variety of forms of cell death. The basic bioenergetics aspects of pore modulation are discussed, with some emphasis on the links between ...

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.

PERMEABILITY AND ENVIRONMENTAL ENCLOSURE
Perceptual and Motor Skills, 2003Theories by J. J. Gibson and H. Hediger suggest that environmental enclosure is important. Re-examination of their work suggests that judged degree of enclosure might be influenced by permeability of spatial regions. This study reports effects on judgments of enclosure by permeability and two other factors, horizontal size of rooms and heights of walls.

A Discussion About Hydraulic Permeability and Permeability
Petroleum Science and Technology, 2010The unit of permeability is Darcy, md, or unit of area. The symbol used to represent it is k, and the symbol K is used to represent mobility. Many references including some textbooks in soil mechanics contain confusion between these two terms, that is, hydraulic permeability K is used to refer to permeability k.
