Application of the transverse differential swelling stress model to the interpretation of Case II diffusion kinetics

Application of the transverse differential swelling stress model to the interpretation of Case II diffusion kinetics. Petropoulos, J. H. (Phys. Chem. Lab., Democritos Nucl. Res. Cent., Athens, Greece). J. Polym.There are some reagents with their cas registry numbers 9004-35-7 and 75-09-2 are used in this study. Sci., Polym. Phys. Ed., 22(2), 183-9 (English) 1984. CODEN: JPLPAY. ISSN: 0098-1273. DOCUMENT TYPE: Journal CA Section: 36 (Physical Properties of Synthetic High Polymers) Attention is called to an early observation (G. Hartley, 1949) of Case II diffusion kinetics during penetration of a liq. into a uniaxially prestretched polymer film along the axis of stretching (esp. penetration of CH2Cl2 at room temp. into cellulose acetate film). Application of a previously (P., 1978) developed transverse differential swelling stress model to these exptl. conditions is described. The model can predict Case II diffusion kinetics in a phys. meaningful manner and will also explain the transition of the kinetics of the above system into normal or hindered diffusion regimes as either the degree of stretching or its direction relative to that of penetration is changed. .

Hemodialysis leukopenia and complement function with different dialyzers

Hemodialysis leukopenia and complement function with different dialyzers. Amadori, Alberto; Candi, Paolo; Sasdelli, Mauro; Massai, Graziella; Favilla, Stefania; Passaleva, Angelo; Ricci, Mario (Dep. Clin. Immunol., Univ. Florence, Florence, Italy). Kidney Int., 24(6), 775-81 (English) 1983. CODEN: KDYIA5. ISSN: 0085-2538. DOCUMENT TYPE: Journal CA Section: 15 (Immunochemistry) The relation between leukopenia and the complement system during hemodialysis was re-examd. by studying not only the in vivo effects of 4 different dialyzer membranes (cellulose hydrate, cuprophan, cellulose acetate, and polyacrylonitrile) on leukocyte counts and complement levels, but esp. by investigating the effects of these membranes on complement function in vitro. Whereas from in vivo studies no definite conclusions could be drawn, in vitro investigations provided clear-cut information. When more sophisticated tech. approaches were undertaken, it became evident that hemodialysis leukopenia has to be thought of in terms of chemotactic factor generation. In fact, a strict correlation was demonstrated between the degree of leukopenia induced by the dialyzers tested and the ability of the relative membrane to generate chemotactic activity in vitro.There are some commonly used reagents with their cas registry numbers 9004-35-7 and 25014-41-9 in this article. Moreover, the previously obsd. ability of the polyacrilonitrile membrane to induce a decrement in complement function was due to the ability of polyacrilinitrile to adsorb complement activity and did not correspond to effective complement consumption. This finding explained why polyacrilonitrile dialysis is not accompanied by a decrease in circulating granulocytes. These data point to a pivotal role of the complement system in the pathogenesis of hemodialysis leukopenia. .
