The effects of intracellular acidification, osmotic shrinkage and ss-adrenergic stimulation on sodium transport across the membrane of lamprey (Lampetra fluviatilis) erythrocytes were investigated. Unidirectional ouabain-insensitive sodium flux, measured using radioactive 22Na, was increased markedly by intracellular acidification, to a lesser extent by osmotic shrinkage and only modestly by ss...

A thermodynamically consistent model for heat and mass transfer in deformable wood fibers is developed. The hybrid mixture theory used to the material as a of three phases, consisting solid, liquid gas phase. solid phase consists dry bound water constituents, whereas has air vapor constituents. Emphasis put on flow exchange moisture both below above saturation point fibers. Generalized forms Fi...

Following unilateral section of the trigeminal third division, the ipsilateral mesencephalic neurons showed severe shrinkage with central chromatolysis and nuclear eccentricity while the motor neurons showed mild swelling. Histochemical reactions in the mesencephalic neurons were mostly characterized by the decreased activity of phosphorylase after 16hrs and concomitant diminution of PAS-positi...

In the context of ridge regression, the estimation of ridge (shrinkage) parameter plays an important role in analyzing data. Many efforts have been put to develop skills and methods of computing shrinkage estimators for different full-parametric ridge regression approaches, using eigenvalues. However, the estimation of shrinkage parameter is neglected for semiparametric regression models. The m...

Human erythrocyte band 3 becomes rapidly phosphorylated on tyrosine residues after exposure of erythrocytes to hypertonic conditions. The driving force for this phosphorylation reaction seems to be a decrease in cell volume, because (1) changes in band 3 phosphotyrosine content accurately track repeated changes in erythrocyte volume through several cycles of swelling and shrinking; (2) the leve...

PURPOSE For asymmetric organ shrinkage caused by heterogeneity dose distribution, tissue elasticity based deformable organ registration cannot be directly applied to the treatment image to construct the treatment dose. A novel approach is proposed to include radiation dose inducible organ shrinkage/deformation in the consideration of treatment dose assessment. METHODS A model and algorithm we...

Abstract Despite extensive research on unsaturated soil behavior in recent decades, the field of transportation engineering still lacks technically and economically feasible methods for identifying expansive soils along roads, particularly regions with limited laboratory infrastructure that are distant from developed areas Brazil. This situation is evident state Acre, located southwest Brazilia...

Cells infected with the vacuolating virus, SV(40), respond by swelling to several times their normal volume. Within enlarged nuclei, virus-containing inclusions appear which are acidophilic and Feulgen-positive. The formation of nuclear inclusions is followed by the appearance of cytoplasmic vacuoles and then shrinkage of the cell. Inclusions were found to exhibit unique double staining when a ...
