Electrostimulable polymeric films with hyaluronic acid and lipid nanoparticles for simultaneous topical delivery of macromolecules and lipophilic drugs.

This study focused on developing electrically stimulable hyaluronic acid (HA) films incorporating lipid nanoparticles (NPs) designed for the topical administration of lipophilic drugs and macromolecules. Based on beeswax and medium-chain triglycerides, NPs were successfully integrated into silk fibroin/chitosan films containing HA (NP-HA films) at a density of approximately 10 NP/cm, ensuring a uniform distribution. This integration resulted in a 40% increase in film roughness, a twofold decrease in Young's modulus, and enhanced film flexibility and bioadhesion work.

Increased β-glucosidase production and its application in agroindustrial residue hydrolysis: A research based on experimental designs.

β-Glucosidases are a limiting factor in the conversion of cellulose to glucose for the subsequent ethanol production. Here, β-glucosidase production by was optimized using Composite Central Designs and Response Surface Methodologies from a medium designed. The coefficient of determination ( ) was 0.

Aluminum directly inhibits alternative oxidase pathway and changes metabolic and redox parameters on Jatropha curcas cell culture.

Aluminum (Al) toxicity has been recognized to be a main limiting factor of crop productivity in acid soil. Al interacts with cell walls disrupting the functions of the plasma membrane and is associated with oxidative damage and mitochondrial dysfunction. Jatropha curcas L.

GH11 xylanase from Aspergillus tamarii Kita: Purification by one-step chromatography and xylooligosaccharides hydrolysis monitored in real-time by mass spectrometry.

The present study describes the one-step purification and biochemical characterization of an endo-1,4-β-xylanase from Aspergillus tamarii Kita. Extracellular xylanase was purified to homogeneity 7.43-fold through CM-cellulose.

Hydrophilic polymeric nanoparticles prepared from Delonix galactomannan with low cytotoxicity for ocular drug delivery.

Delonix is a galactomannan polysaccharide extracted from the endosperm of Delonix regia plant. This study aims at the development of Delonix nanoparticle and assesses its potential for ocular delivery by evaluating its in-vitro stability, toxicity and cellular uptake. Fluorescent nanoparticles (BODIPY-loaded nanoparticles) were prepared by a Quality-by-Design modified nanoprecipitation technique.
