Ameliorated delivery of Amphotericin B to Macrophages using Chondroitin Sulfate Surface-Modified Liposome Nanoparticles.

Background: The neglected tropical disease leishmaniasis has significant adverse effects from current treatments and limited therapeutic options are currently available.

Objective: The aim of this study was to develop a surface-modified nano-liposomal drug delivery system, anchored with chondroitin sulfate (CS), to effectively transport Amphotericin B (AmB) to macrophages.

Methods: Conventional liposome formulations (CL-F) and CS-coated surface-modified liposome formulations (CS-SML-F) were formulated by the thin film hydration method and characterized for particle size, polydispersity index (PDI), zeta potential and entrapment efficiency with long-term stability.

evaluation of physicochemical-dependent effects of polymeric nanoparticles on their cellular uptake and co-localization using pulmonary calu-3 cell lines.

Objective: The study evaluated physicochemical properties of eight different polymeric nanoparticles (NPs) and their interaction with lung barrier and their suitability for pulmonary drug delivery.

Methods: Eight physiochemically different NPs were fabricated from Poly lactic-co-glycolic acid (PLGA, PL) and Poly glycerol adipate-co-ω-pentadecalactone (PGA-co-PDL, PG) emulsification-solvent evaporation. Pulmonary barrier integrity was investigated using Calu-3 under air-liquid interface.

Toxicological assessment of nanoparticle interactions with the pulmonary system.

Nanoparticle(NP)-based materials have breakthrough applications in many fields of life, such as in engineering, communications and textiles industries; food and bioenvironmental applications; medicines and cosmetics, etc. Biomedical applications of NPs are very active areas of research with successful translation to pharmaceutical and clinical uses overcoming both pharmaceutical and clinical challenges. Although the attractiveness and enhanced applications of these NPs stem from their exceptional properties at the nanoscale size, i.

Carriers for the targeted delivery of aerosolized macromolecules for pulmonary pathologies.

Introduction: Macromolecules with unique effects and potency are increasingly being considered for application in lung pathologies. Numerous delivery strategies for these macromolecules through the lung have been investigated to improve the targeting and overall efficacy.

Areas Covered: Targeting approaches from delivery devices, formulation strategies and specific targets are discussed.

Comparative Cytotoxicity of Glycyrrhiza glabra Roots from Different Geographical Origins Against Immortal Human Keratinocyte (HaCaT), Lung Adenocarcinoma (A549) and Liver Carcinoma (HepG2) Cells.

Glycyrrhiza glabra L. (Fabaceae), commonly known as 'liquorice', is a well-known medicinal plant. Roots of this plant have long been used as a sweetening and flavouring agent in food and pharmaceutical products, and also as a traditional remedy for cough, upper and lower respiratory ailments, kidney stones, hepatitis C, skin disorder, cardiovascular diseases, diabetes, gastrointestinal ulcers and stomach ache.
