Physicochemical Characterization of Lecithin/Isopropyl Myristate Reverse Micelles

“…This allows the micelle to penetrate the stratum corneum and move into blood circulation where it undergoes biodegradation and releases the drug for therapeutic effects. [4,5] Second, the solution induces monopodial growth of reverse micelles that then develop into pillared aggregates. When those aggregates reach a certain length, they generate a three-dimensional network of liquid crystal gels.…”

“…[12] These tools have also been used as transdermal delivery vehicles. [13][14][15][16][17][18][19][20][21][22][23][24] Non-polar groups and non-polar organic solvent contact each other in reverse micelles, while polar groups are arrayed inside and form a polar core that can dissolve polar substances. When aqueous drugs enter this polar core, a "water pool" can form and accommodate a large quantity of water-soluble drugs.…”

Immune Cell Number, Phenotype, and Function in the Elderly with Sepsis

“…Despite these conflicting studies regarding the number of DCs, the function of DCs has been shown to change significantly with age [94]. Agrawal et al observed that DCs isolated from elderly individuals display a proinflammatory phenotype characterized by the increased basal secretion of proinflammatory cytokines, such as IL-6 and TNF-α, which may be closely related to the senescence-associated secretory phenotype, one of characteristics of immunosenescence [95][96][97]. In addition, Li et al observed that CD8α + DCs in elderly mice display poor upregulation of costimulatory molecules for MHC-II and CD40, which may produce a less effective T cell priming environment [98].…”

Dielectric and Thermal Properties of Carrot Fibers –Epoxy Composites

“…The measurements of dissipation factor of an insulating material are important, since the loss tangent is a measure of the electrical energy that is converted to heat in an insulator [3]. The dielectric properties of natural fibers-polymer composites such as banana, jute, sisal, coir, pineapple, waste paper, oil palm, flax fibers were investigated [5,[9][10][11][12][13][14].…”
