One of the CAI applications tested was the "LUMEN Forum", which allowed asynchronous communications among course faculty and students utilizing WebBoard conferencing server software.
Intraluminal aortic clamping has been achieved until now by means of a sophisticated device consisting of a three-lumen catheter named Endoclamp, which allows at the same time occlusion of the aorta, antegrade delivering of cardioplegia, and venting through the aortic root.
It uses a specially designed cannula that consists of a flexible plastic cone with a pointed metal tip at its end to dilate the trachea from its lumen outward to the skin, which allows less tissue trauma and enhances safety.
"If I try to shorten the scope, I can keep some right torque on this point which keeps the lumen… The general strategy that I use is to keep the lumen on my right… which allows me to try and maintain a straight scope as we traverse through the sigmoid colon....because, as you go through the sigmoid colon, the instrument wants to loop.... I'm having trouble finding the lumen.
We believe that a third possibility to explain the constrained phenotype of mycobacteria in DCs-altered phagosome acidification - is unlikely because the phagosomal lumen is kept slightly alkaline in DCs, which allows moderate antigen degradation and proper antigen presentation [27].
Acidification of the endosomal vesicular lumen induces conformational changes of the toxins which allows the insertion into the vesicle membrane and translocation of the N-terminally located catalytic glucosyltransferase (GT) domain into the cytosol.
As a result, CO2 removal is more efficient and achieved with a smaller membrane surface area and flows of 400 to 600 ml.minute-1, which allows use of smaller double-lumen catheters.
The disruption of the tight junctions and IEC death lead to the impairment of the epithelial barrier and an increase of its permeability, which allows the gluten peptides in the lumen to enter the lamina (reaction #13).
The advantages of an SFR device are the simplicity of the setup machinery and the small dimensions of the fiber-optic probes, which allows e.g. measurement through the lumen of FNA-needles [ 24, 25].
The analyzer is designed in such a way that the dilute sodium bicarbonate carrier/stripping solution flows downward by gravity into the lumen side of the hollow fibers in the HFM module which allows efficient contact with the gas stream.
