AI Article Synopsis
Article Abstract
Background: Noncultured Epidermal Cell Suspension (NCECS) is a surgical modality used in treating stable vitiligo. Trypsinization of the epidermis may be done either at 4°C overnight (cold) or at 37°C for 30 to 50 minutes (warm). Recently, trypsinization was done at room temperature (25°C) in an in vitro trial.
Objective: To compare different trypsinization techniques in NCECS regarding cell viability and clinical outcome.
Methods: This comparative multicenter study was conducted on 20 patients with stable nonsegmental vitiligo. In each patient, 3, nonacral vitiligo lesions were randomly assigned for treatment by NCECS prepared by warm, room temperature, and cold trypsinization techniques, respectively. A perilesional biopsy was taken from each of the 3 treated lesions as an objective measure of disease stability. After transplantation, all patients received narrow-band ultraviolet B twice weekly for 6 months. Cell viability was assessed in each technique, as well as clinical outcome in all treated lesions.
Results: Warm and room temperature trypsinization techniques were comparable with each other. Both were significantly better than the cold technique regarding viability and repigmentation.
Conclusion: Room temperature trypsinization can be used as a convenient substitute to warm trypsinization. Cold trypsinization is not recommended because of its poor results and poor patient satisfaction.

Development of Spray-Dried Micelles, Liposomes, and Solid Lipid Nanoparticles for Enhanced Stability.
Pharmaceutics
January 2025
Department of Pharmaceutics and Medicinal Chemistry, University of the Pacific, Stockton, CA 95211, USA.
Micelles, liposomes, and solid lipid nanoparticles (SLNs) are promising drug delivery vehicles; however, poor aqueous stability requires post-processing drying methods for maintaining long-term stability. The objective of this study was to compare the potential of lipid-based micelles, liposomes, and SLNs for producing stable re-dispersible spray-dried powders with trehalose or a combination of trehalose and L-leucine. This study provides novel insights into the implementation of spray drying as a technique to enhance long-term stability for these lipid-based nanocarriers.

Pharmaceutics
December 2024
Faculty of Pharmacy, University of Ljubljana, Aškerčeva Cesta 7, 1000 Ljubljana, Slovenia.
Background/objectives: Lactoferrin (Lf), a multifunctional iron-binding protein, has considerable potential for use as an active ingredient in food supplements due to its numerous positive effects on health. As Lf is prone to degradation, we aimed to develop a formulation that would ensure sufficient stability of Lf in the gastrointestinal tract and during product storage.
Methods: A simple, efficient, and well-established technology that has potential for industrial production was used for the double-coating of neutral pellet cores with an Lf layer and a protective enteric coating.
Bioadhesive Chitosan Films Loading Curcumin for Safe and Effective Skin Cancer Topical Treatment.
Pharmaceutics
December 2024
Laboratory of Food, Drugs, and Cosmetics (LTMAC), University of Brasilia, Brasília 70910-900, Brazil.
: This study aimed to evaluate the safety and efficacy of chitosan-based bioadhesive films for facilitating the topical delivery of curcumin in skin cancer treatment, addressing the pharmacokinetic limitations associated with oral administration. : The films, which incorporated curcumin, were formulated using varying proportions of chitosan, polyvinyl alcohol, Poloxamer 407, and propylene glycol. These films were assessed for stability, drug release, in vitro skin permeation, cell viability (with and without radiotherapy), and skin irritation.

Polymers (Basel)
January 2025
Danish Polymer Centre, Department of Chemical and Biochemical Engineering, Technical University of Denmark, 2800 Kgs. Lyngby, Denmark.
Plug and abandonment of offshore oil wells is a costly and time-consuming process, yet it is necessary for the ever-increasing number of mature fields in the region of the Danish North Sea, as well as globally. Current practices ensuring durable solutions for the complete zonal isolation of oil wells have a large environmental impact. This paper proposes a novel resin that could be mixed on the platform and pumped into the tubing in a liquid state.

This article systematically investigated the improvement effect of polypropylene fiber (PPF) on the mechanical and freeze-thaw properties of alkali-activated fly ash slag concrete (AAFSC) with high fly ash content and cured at room temperature. Fly ash and slag were used as precursors, with fly ash accounting for 80% of the total mass. A mixed solution of sodium hydroxide and sodium silicate was used as alkali activator, and short-cut PPF was added to improve the performance of AAFSC.
