Briefly, that theory suggests that parietal cells undergo the following morphological alterations: they have a large active secretory surface during the stimulatory phase, and they display a minimal active secretory surface during the resting phase.
But in actual fact, the evolution of this process, far from these steps, is more dynamically undergoing subtle alteration of the cancer cells themselves synergized with modeling of the tumor microenvironment and the premetastatic sites (or niche).
The addition of the Clifton Maybank corridor, built in the 18th century from stone obtained from another house then undergoing alteration, allowed the principal ground- and first-floor rooms to have some privacy from the servants' areas and linked the two staircases.
By John McCarten and M. M. Silver The New Yorker, January 17 , 1959P. 21 Incidental Intelligence: The Metropolitan Life Building is undergoing some alterations, and on the fence that surrounds the operation there is a chalked message reading, "Down with Variable Annuities".
To survey for genome instability, the genomic fractions of copy number gain, loss, and CNNLOH were estimated by dividing the number of SNPs undergoing a specific alteration by the total number of SNPs present in the respective chromosome or in the respective sample.
Throughout the years, the house has undergone significant alteration, including the addition of a gable roof.
Incidental Intelligence: The Metropolitan Life Building is undergoing some alterations, and on the fence that surrounds the operation there is a chalked message reading, "Down with Variable Annuities".
The genes undergoing such alterations in cancer have been reported to be repressed in hESCs by the establishment of "bivalent chromatin domains" consisting of activating (H3 lysine 27 methylation) and repressing (H3 lysine 4 methylation) histone marks that keep them poised for activation but, at the same time, predisposes them to aberrant promoter hypermethylation in adult cancers [7] [9].
This population deserves specific attention in the development of radioprotective agents because pediatric and adult brains differ markedly with the former undergoing dynamic alterations in synaptic density and metabolism throughout development (Huttenlocher 2002).
One structure that will be undergoing alterations is the urbane Italian Renaissance four-story office building at 50 Madison Avenue, which was built as the headquarters of the A.S.P.C.A.
