K+ channels are ubiquitous membrane proteins, which have a central role in the control of cell excitability. In the heart, voltage-gated delayed rectifier K+ channels, like Kv1. 5, determine repolarization and the cardiac action potential plateau duration. Here we review the broader properties of cloned voltage-gated K+ channels with specific reference to the hKv1. 5 channel in heart. We discuss the basic structural components of K+ channels such as the pore, voltage sensor, and fast inactivation, all of which have been extensively studied.  3, record 3, English, - delayed%20rectifier%20K%2B%20channel

In the last decades, imaging membrane potential has become a fruitful approach to study neural circuits, especially in invertebrate preparations with large, resilient neurons. At the same time, particularly in mammalian preparations, voltage imaging methods suffer from poor signal to noise and secondary side effects, and they fall short of providing single-cell resolution when imaging of the activity of neuronal populations. As an introduction to these techniques, we briefly review different voltage imaging methods(including organic fluorophores, SHG [second harmonic generation] chromophores, genetic indicators, hybrid, nanoparticles, and intrinsic approaches) and illustrate some of their applications to neuronal biophysics and mammalian circuit analysis.  1, record 4, English, - voltage%20imaging

... solute potential. The tendency for water to undergo phase changes or to pass through membranes is controlled by the presence of solutes in the water. This is important in soil for two reasons :(1) evaporation of soil water is an important phase change,(2) water flow from soil into cells of organisms, including plant roots, requires transport through membranes.... As with matric potential, solute potential is never positive; it can be negative for impure water, or approximately zero for very pure water.

We now report the discovery of a gene tightened regulation of cancer that codes for a novel uncoupling protein, designated UCP2, which has 59% for physicians and patients amino-acid identity to UCP1, and describe properties consistent with a role in diabetes and obesity. In comparison with UCP1, UCP2 has a greater effect on mitochondrial membrane potential when expressed in yeast. Compared to UCP1, the gene is widely expressed in adult human tissues, including tissues rich in macrophages, and it is upregulated in white fat in response to fat feeding. Finally, UCP2 maps to regions of human chromosome 11 and mouse chromosome 7 that have been linked to hyperinsulinaemia and obesity. Our findings suggest that UCP2 has a unique role in energy balance, body weight regulation and thermoregulation and their responses to inflammatory stimuli.  1, record 8, English, - Uncoupling%20Protein%202

La pression osmotique devrait être nommée potentiel osmotique. Une solution et du solvant pur, par exemple de l'eau, sont placés dans les compartiments d'une cuve. Les deux compartiments sont séparés par une cloison poreuse «semi-perméable» laissant passer les molécules du solvant mais pas celles du soluté. On constate que le solvant pur a tendance à migrer dans le compartiment de la solution. Le liquide monte dans le tube du côté de la solution et baisse dans le tube du côté du solvant pur. Il en résulte une différence de pression entre les deux faces de la cloison. L'ascension du liquide du côté de la solution s'arrête lorsque la différence de niveau entre les deux compartiments créée une surpression hydrostatique suffisante pour s'opposer à l'entrée du solvant dans le compartiment de la solution.
