Chemical, radiochemical and x-ray microanalysis assays were used to define parameters of silicon (Si) retention during preparation og biologic samples (rat liver, spleen, kidney, lung, diatoms and cell organelles) for x-ray microanalysis, Due to its

This investigation confirms the presence of the inducible mixed function hydroxylase enzyme system in nuclear membranes. The cytochrome P-450 spectrum and demethylase activity, markers of the enzyme system, were used to define its localization to the

The in vivo uptake of 31Si-silicic acid and 68Ge-germanic acid by cell organelles of Nitzschia alba Lewin and Lewin and Cylindrotheca fusiformis Reimann and Lewin was demonstrated. The organelles were isolated by fractionation of pre-labeled cells by

Uptake of Si and Ge (chemical analogue of Si) in rat tissues was compared to establish their subcellular localization and determine if Ge could be used to trace Si in situ . 31 Si and 68 Ge were found in tissues and in cell organelles after injection

A critical evaluation was made of the hypothesis that the primary mode of action of ethylene in inducing physiological responses is by changing the permeability of cell organelles. The parameter investigated was the evaluation of the influence of eth

Reversible alteration of the surface tension of thin films of lipids, proteins and mixtures of both resulted when the thin films were treated with ethylene and other aliphatic gases. This effect appeared to be a nonspecific surface effect related to

Electron probe microanalysis of unfixed freeze-substituted rat liver tissue embedded in Spurr's low viscosity epoxy resin demonstrated the occurrence of Si as well as P, S, and Cl in the nucleus, nucleolus, mitochondria, and rough endoplasmic reticul
