In vitro diffusion of butorphanol from But-P407 25% through a biological membrane
was compared with that of a butorphanol solution.
However excessive mobility of the biological membrane
made both suture techniques difficult, and constant repositioning was required during the suture procedure.
Formulation: An Exploration of Sports Scheduling through the Use of Graph Theory and Linear Programming," and Michelle Muzzio presented "Advances of the Droplet Interface Bilayer (DIB): Modeling the Biological Membrane
The same interaction when occurs with the mucus layer of the biological membrane
, is referred as mucoadhesion.
This strange energy conversion process works by using externally supplied energy to constantly pump a lot more protons onto one side of a biological membrane
than the other and then having them flow back "downhill" immediately, but only through a turbine-like molecular engine which creates a chemical fuel called ATP; a fuel that cells "burn" in order to power vital cell processes.
Surface area to volume ratio is an important factor that governs the rate and the extent of absorption/diffusion of a chemical moiety across the biological membrane
In a biological membrane
seen through an electron microscope, the fixation process causes the protein layers to appear as dense lines, but the phospholipid layers are transparent.
Design and preliminary evaluation of a novel gravity independent rotating biological membrane
In one aspect, the method comprises; a) providing a living cell with a first reagent comprising a charged hydrophobic molecule which is typically a fluorescence resonance energy transfer acceptor or donor, or is a quencher and is capable of redistributing within the membrane of a biological membrane
in response to changes in the potential across the membrane; b) providing the cell with a second reagent that can label the first face or the second face of a biological membrane
within the cell; c) detecting light emission from the first reagent or the second reagent.
The structural arrangement of the Polyamide S membrane with its three-layer design and micro domain surface resembles that of nature's own biological membrane
The metallic objects have a small, central core which is a metallic rod and these are covered with a strange biological membrane
that seems to prevent the body from reacting to the object.
One of the most important properties of the biological fluids is hydraulic permeability, which decides the movement of solvent through biological membrane
