“…The P~ fraction was isolated from brain hemispheres as described [6] and purified on a discontinuous sucrose gradient [6]. Synaptic vesicles were obtained by 1-h incubation of P~ fraction in 5 mM Tris buffer (hypotonic shock).…”

The possibility of the use of saponin for permeabilization of synaptic vesicles from P2 fraction is explored. This fraction is isolated from rat brain cortex. Phosphorylation of membrane-bound proteins is performed in vitro. At the saponin:protein ratio 1:10 (w/w) phosphorylation of these proteins increases 2-fold due to increased membrane permeability for ATP and cAMP. Treatment of synaptic vesicles with saponin at the same ratio leads to the loss of cytosolic but not membrane-bound protein. This concentration of saponin can be used for permeabilization of other membranes, providing that the protein:cholesterol ratio is taken into consideration.

“…Fossil diatoms are photosynthetic organisms that live in freshwater or marine and they constitute a very important part of the phytoplanktons. The presence of diatom valves in marine paleoenvironments has been used for studying the climatic changes as well as geomorphological processes [12,13]. The identification of diatom fossils requires the analysis of a great number of valves per sample.…”

In this paper, algorithms invariant to position, rotation, noise and non-homogeneous illumination are presented. Here, several manners are studied to generate binary rings mask filters and the corresponding signatures associated to each image. Also, in this work it is shown that digital systems, which are based on the k-law non-linear correlation, are k-invariant for 0 < k < 1. The methodologies are tested using greyscale fossil diatoms digital images (real images), and considering the great similarity between those images the results obtained are excellent. The box plot statistical analysis and the computational cost times yield that the Bessel rings masks are the best option when the images contain a homogeneous illumination and the Fourier masks digital system is the right selection when the non-homogeneous illumination and noise is presented in the images.
