The suitability of three vapor deposition techniques for pore size modification was evaluated using polycarbonate track etched membranes as model supports. A feature scale model was employed to predict the pore geometry after modification and the resulting pure water flux. Physical vapor deposition (PVD) and pulsed plasma-enhanced chemical vapor deposition (PECVD), naturally, form asymmetric na...

The receptor for thyrotropin-releasing hormone has been located in the plasma membranes of bovine anterior pituitary gland. Treatment of membranes with phospholipase A, phospholipase C, or digitonin or addition of lysophosphatidylcholine diminishes or completely destroys the ability of membranes to bind 3H-labeled thyrotropin-releasing hormone. Phospholipase D was without effect. These reductio...
