Free radical label: new approach to the study of super-slow molecular dynamics of lipid systems

open access: yesJournal of Lipid Research, 1981
A new method of EPR-spectroscopy, the recombination of free radicals appearing as a result of indirect radiolysis of biological molecules after a low temperature irradiation, was applied to the study of molecular dynamics of dimyristoyl ...

Use of X-ray microanalysis for study of cation distribution in potassium deficient pumpkin roots

open access: yesActa Societatis Botanicorum Poloniae, 2014
Ice slices of root tissues were investigated by X-ray microanalysis. It is shown that the cytoplasm of the meristematic and differentiated cells of potassium dificiest roots maintains a high potassium level.

Experimental study of embryo differentiation in angiosperms

open access: yesActa Societatis Botanicorum Poloniae, 2014
By comparison of peony and lotus embryos in in vitro culture we established differences in their morphogenetic potential. We traced in peony embryo culture: embryogenesis, embryoidogenesis, organogenesis and histogenesis, whereas the lotus embryo ...

Interaction of fatty acid sodium salts with sodium deoxycholate

open access: yesJournal of Lipid Research, 1987
Interaction of homologous fatty acids (C3-C18) with sodium deoxycholate was investigated. From NMR and ultrasonic results it was found that short chain homologues (up to C9) do not participate in the formation of mixed micelles with sodium deoxycholate ...
