There are various commercially available setups for studying drug permeation, which differ in cost and manual labor. We explore an artificial membrane in an NMR tube to assess drug permeation with automated measurements. NMR-based concentrations were validated with HPLC and compared to a conventional setup. Setup-specific challenges and workarounds as well as future setup-designs for this and other applications are discussed.

This investigation aimed to enhance transdermal methotrexate delivery through human skin by employing Dr. Pen microneedles and poly(d,l-lactide--glycolide) acid microparticles formulated from eight polymer grades (Expansorb DLG 95-4A, DLG 75-5A, DLG 50-2A, DLG 50-5A, DLG 50-8A, DLG 50-6P, DLG 50-7P, and DLL 10-15A). A comprehensive characterization of the microparticles was performed, encompassing various parameters such as size, charge, morphology, microencapsulation efficiency, yield, release kinetics, and chemical composition.

This study reports the preparation of hydrogels (HG) made with xanthan gum (XG) and ƙ-carrageenan (KC) polysaccharides containing ketoprofen (KET)-loaded nanoemulsions (NK) and their evaluation in a rheumatoid arthritis (RA) model. The nano-based HGs exhibited nanometric-sized droplets (~ 100 nm), an acidic pH (5.10-6.

Cold atmospheric plasma (CAP) has been utilized in various medical devices using its oxidative nature. Recent studies have provided evidence that CAP can facilitate the delivery of large, hydrophilic molecules through the epidermis to the dermis. On the other hand, a new approach called low-intensity CAP (LICAP) has been developed, allowing the plasma level to be controlled within a subtoxic range, thereby demonstrating various biological benefits without tissue damage.

Skin cancer stands as a challenging global health concern, necessitating innovative approaches to cure deficiencies within traditional therapeutic modalities. While conventional drug delivery methods through injection or oral administration have long prevailed, the emergence of topical drug administration presents a compelling alternative. The skin, aside from offering a swift and painless procedure, serves as a reservoir, maintaining drug efficacy over extended durations.

Bacteria, fungi, and algae are examples of microorganisms that synthesize polysaccharides, which are macromolecules that belong to the carbohydrate class. Production of polysaccharides represents an alternative to chemical and plant-derived compounds that could be used for human well-being which requires implementation of different methods standardized during the extraction and purification process. In the current investigation, Pseudolagarobasidium acaciicola, a novel fungal source of exopolysaccharide (EPS) was used which produced 2773.
