The role of arginine in the binding of LTD4 antagonists to Cys LT1 receptors of guinea pig ileum.

Using the chemical masking agent phenylglyoxal, we have selectively blocked the arginine residues in leukotriene cysL

Polymer foam comprising a polymer and nanoparticles, and nanoparticles for the manufacture of such foam.

A polymer foam is produced comprising a polymer and nanoparticles having a maximum dimensionof 750 nm, which foam has cells with an average cell size of at most 1 µm and a cell density of at least 1012 cells/ml, wherein polymeric grafts have been attached to the nanoparticles. The nanoparticles may be particles with a solid core or porous hollow core-shell particles. The foam can be manufactured by dispersing the nanoparticles in a polymer to yield a dispersion; by adding a blowing agent to the dispersion to obtain an expandable mixture; and by foaming the expandable mixture to obtain the polymer foam

Does the tenary complex act as a secondary proton pump and a GTP synthase?

It has been suggested that G protein-coupled receptors can act as proton transporters, with the activated G protein-coupled receptor transporting
