Active Transport May Dominate over Diffusion for Macromolecules For mostmacromolecules, intracellular movement is often viaactive transportrequiring ATP. Active transport is especially important in cells with extended morphologies, such as neurons. In neurons, calculations indicate that passive diffusion of mR...
In most instances, secondary active transport involves only two species (Na+ and another substrate), but in some cases there are three: an example is the Na+-K+-2Cl− co-transporter, an electroneutral symporter that is expressed principally in epithelial cells. This transporter accounts for ...
of the same parity and bring them close to the modes of opposite parity. This birefringence can be provided by organic materials, for example, perylenes (C20H12)36. Perylenes are nowadays widely used in optics due to their intense light absorption and luminescence in the visible range, high ...
An availability database is sometimes called adatabase replicain Transact-SQL, PowerShell, and SQL Server Management Objects (SMO) names. For example, the term "database replica" is used in the names of the Always On dynamic management views that return information about availability databases:sy...
We next assessed the activation of matrix-producing cells into a myofibroblast phenotype, a key contractile cell in fibrosis progression. The IA group exhibited a significant reduction in αSMA expression when compared to the control at 2 weeks (Fig.4d, e). Despite observing differences in individ...
The specialisation of mammalian cells in time and space requires genes associated with specific pathways and functions to be co-ordinately expressed. Here we have combined a large number of publically available microarray datasets derived from human prim
