Interferons: Purification and Physicochemical Aspects

Antiviral interferon activity in any one species can be exhibited by a variety of substances that differ in their physical and chemical properties, but the nature of these differences is not understood. Conditions that can lead to the formation of diverse types of interferons have been outlined. Reasons have been adduced why, for certain purposes, purification of interferons is desirable or eve...

Physicochemical and Structural Aspects of Nucleic Acids

Lipid membranes with grafted polymers: physicochemical aspects.

Membranes grafted with water-soluble polymers resist protein adsorption and adhesion to cellular surfaces. Liposomes with surface-grafted polymers therefore find applications in drug delivery. The physicochemical properties of polymer-grafted lipid membranes are reviewed with mean-field and scaling theories from polymer physics. Topics covered are: mushroom-brush transitions, membrane expansion...

Preparation, Evaluation and Physicochemical aspects of Tadalafil Co-crystals

The aim of the present work was to prepare and evaluate cocrystals of a 1:1 stoichiometric molar ratio of Tadalafil (TDF). Liquid assisted grinding method was explored and the cocrystals were evaluated for their physicochemical properties, bioavailability and residual solvent study. Their preparation was confirmed and characterized by spectroscopic (FT-IR), crystallographic (XRPD) and thermoana...

Physicochemical Aspects of the Plasmodium chabaudi-Infected Erythrocyte

Membrane electrochemical potential is a feature of the molecular profile of the cell membrane and the two-dimensional arrangement of its charge-bearing molecules. Plasmodium species, the causative agents of malaria, are intracellular parasites that remodel host erythrocytes by expressing their own proteins on erythrocyte membranes. Although various aspects of the modifications made to the host ...
