The Hall Method In The Quantitative X-Ray Microanalysis Of Biological Specimens: A Review, Godfried M. Roomans
The Hall Method In The Quantitative X-Ray Microanalysis Of Biological Specimens: A Review, Godfried M. Roomans
Scanning Microscopy
In the two decades since its inception by T.A. Hall, the continuum theory of quantification has become the general method for quantitative analysis of biological specimens. Although the method was originally developed for thin specimens, its use has been extended to thicker specimens, and it has also been used in quantitative determinations of local water content. The single most important difficulty in the application of the "Hall method" is the accurate calculation of the extraneous continuum, i.e., the continuum due to non-specimen sources. The different variations in methods for quantitative analysis of local water content are critically compared and a …

The Physical State Of Potassium Ion In The Living Cell, G. N. Ling
Scanning Microscopy
This review summarizes more than 30 years of experimental testing (and confirmation) of a key postulate of the association-induction (AI) hypothesis: most K+ ions in resting cells are adsorbed on 𝛃-and 𝛄-carboxyl group of cell proteins in a close-contact one ion-one site manner. Failure of healthy, cytoplasm-free, squid axon-membrane sacs to selectively accumulate K+ over Na+ and success of muscle cells without a functional cell membrane (and postulated pumps) to achieve the same, point to the cytoplasm as the seat of selective K+ accumulation. Four independent techniques unanimously confirmed the predicted localization in striated muscle cells, …
