Mathematical Description of the Functioning of the Pulsatory Liposome [PDF]

INCAS Bulletin, 2023
We consider a liposome filled with the aqueous solution of an osmotic solute enclosed in a large water bath. Due to osmotic pressure, it works according to a sequence of cycles with two stages.

The pulsatory liposome works as a neuronal network (II) [PDF]

INCAS Bulletin
In this paper we consider a unilamellar liposome (lipid vesicle) filled with aqueous solution of an osmotic solute. This liposome is introduced in a hypotonic aqueous medium of large dimensions.

Simulation of pulsatory liposome working using a linear approximation for transmembrane pore dynamics [PDF]

INCAS Bulletin
This paper presents an analytical solution of the differential equations describing the pulsatory liposome dynamics. We consider a unilamellar liposome filled with an aqueous solution of osmotic solute inserted in a hypotonic aqueous medium.

Pulsatory Liposome: A Possible Biotechnological Device [PDF]

, 2023
A unilamellar liposome filled with an osmotic solution is introduced into a hypotonic aqueous environment. Because of the mechanical tension induced by the osmotic flow, the vesicle swells up to a critical size, when suddenly a transbilayer pore appears and the vesicle relaxing stage starts.

EVOLUTION OF THE PULSATORY LIPOSOME BY ANALYTICAL METHODS

Annals of the Academy of Romanian Scientists. Series on Physics and Chemistry
This paper is a review for the analytical modelling of the biophysical engine represented by a liposome, filled with an osmotic solution, introduced into an aqueous medium. The processes leading to the appearance, evolution and dis- appearance of the liposome-pore are presented. Due to osmosis, the liposome grows to a maximum size that will lead to the

Analytical and numerical results for the pulsatory liposome [PDF]

INCAS Bulletin
In this work, we consider a special and interesting bionic object - the pulsatory liposome, which are an unilamellar liposome (lipid vesicle) filled with aqueous solution of osmotic solute.

Towards bottom-up reconstitution of minimal modules of eukaryotic pattern formation [PDF]

, 2018
Segundo o Sindicato Nacional da Indústria de Produtos para Defesa Vegetal, de 2012 a 2014, cerca de 10% do total de agrotóxicos comercializados no Brasil foram destinados para o setor sucroalcooleiro.

Principles and theory of protein-based pattern formation [PDF]

, 2021
Biological systems perform functions by the orchestrated interplay of many small components without a "conductor." Such self-organization pervades life on many scales, from the subcellular level to populations of many organisms and whole ecosystems.
