Investigating the effect of clay content and type on the mechanical performance of calcium alginate-based hybrid bio-capsules.

This study aims to investigate the mechanical behavior of alginate-based simple and alginate@clay-based hybrid capsules under uniaxial compression using a Brookfield force machine. The effect of clay type and content on Young's modulus and nominal rupture stress of the capsules was investigated and characterized using Scanning Electron Microscopy (SEM), and Fourier Transform Infrared Spectroscopy (ATR-FTIR). Results showed that clay content improves the mechanical properties depending on its type.

Gas chromatography coupled to mass spectrometry characterization, anti-inflammatory effect, wound-healing potential, and hair growth-promoting activity of Algerian L ().

Objectives: The roots of have been used by the population of Northern Algeria to treat several pathological conditions, including wound healing and hair growth. The present study was conducted to evaluate the anti-inflammatory activity, wound-healing potential, and hair growth-promoting activity attributed to root.

Materials And Methods: In this study, we have investigated the anti-inflammatory effect using carrageenan-induced paw edema test, evaluated the wound-healing potential by linear incision wound model, and evaluated hair growth activity using hair growth-promoting test attributed to root.

Thermoreversible gelation in aqueous binary solvents of chemically modified agarose.

The thermoreversible gelation of chemically modified agarose has been studied in aqueous binary solvents (dimethyl sulfoxide and a series of formamide) by differential calorimetry, mechanical testing, and small-angle neutron scattering. The temperature-composition phase diagrams have been established. It is concluded that gelation is promoted by the formation of ternary complexes modified agarose/water/cosolvent, wherein the cosolvent mediates the interaction between chains through the formation of electrostatic interactions.
