WASTE indexes published research — it does not host or republish full papers. Each entry is a metadata record compiled from open scholarly databases; the abstract is shown in full only where the paper is openly licensed, otherwise a short excerpt under fair use. Classifications are automated and approximate.

BACKGROUND: POR*28 is a recently newly described allelic variant of the cytochrome P450 oxidoreductase (POR), which might be associated with an increased metabolic activity of P450 cytochromes (CYP) 3A5 and 3A4. Consequently, carriers of…

The performance of colon-targeted solid dosage forms is commonly assessed using standardised pharmacopeial dissolution apparatuses like the USP II or the miniaturised replica, the mini-USP II. However, these fail to replicate the hydrodynamics and shear stresses in the colonic environment, which is crucial for the tablet's drug release process. In this work, computer simulations are used to create a digital twin of a dissolution apparatus and to develop a method to create a digital twin of a tablet that behaves realistically. These models are used to investigate the drug release profiles and s

Introduction: Vaginal candidiasis remains a recurrent fungal infection affecting millions of women worldwide, necessitating innovative local delivery systems to overcome poor drug solubility and mucosal barriers. This study introduces Dual-Functional Hybrid Cationic PEGylated Proniosomes (DHCPP) as a smart nano-platform designed to boost the vaginal delivery of Fenticonazole Nitrate (FTN). Methods: DHCPP systems were fabricated via the coacervation phase separation method and optimized using a full 2 3 factorial design, achieving a high desirability value of 0.931. The optimized DHCPP exhibite

Abstract This research focuses on creating a novel Brijaluronic-based terpesomal system capable of transporting quercetin (QER) efficiently to the brain. The vesicles were fabricated through an ethanol-injection method and then refined using a structured optimization approach in Design-Expert® software. The influence of three main formulation parameters: terpene-to-drug ratio, surfactant type, and hyaluronic acid amount were evaluated. The optimization process was designed to maximize EE%, minimize VS, and maintain ZP within an acceptable stability range. The optimal formula hit a desirability

Abstract This study introduces and statistically optimizes novel Tetra-Synergistic Bilosomes (TSB), an advanced nano-platform for topical delivery of voriconazole (VOR) in otomycosis therapy. The term “Tetra-Synergistic” reflects the incorporation of four complementary components: Cremophor® EL, sodium deoxycholate, Brij® 58, and Brij® S2, working in synergy to enhance therapeutic efficacy. TSB was fabricated using the thin-film hydration method and optimized through a 2 3 D-optimal design. Three formulation factors were investigated: Cremophor® EL: VOR ratio, sodium deoxycholate: cholesterol

The self-assembly of glycyrrhizic acid (GA) in aqueous solutions has significant implications for soft matter science and material design. Here, we describe the self-assembly of GA under well-defined conditions, focusing on measurements of the critical aggregation concentration (CAC) - when GA dimers start stacking into nanofibrils, and of the critical gel concentration (CGC) - when nanofibrils entangle into a viscoelastic network. We examine in detail the structure at low concentrations and its evolution into a viscoelastic hydrogel, addressing the kinetic pathway. We highlight the dependence

Acetaminophen (APAP)-induced liver injury and acute liver failure is a significant clinical problem worldwide; in addition, APAP overdoses in animals or in cell culture are used as popular models to study drug-induced liver injury mechanisms and test therapeutic interventions. Early assumptions that APAP toxicity is caused by a single mechanism resulting in a defined mode of cell death in hepatocytes had to be questioned when over the years many different mechanisms and modes of cell death were reported. Although many of the contradictory results and conclusions reported over the years can be
