In this study, an optimized environmentally friendly procedure was employed to enhance the sustainable utilization of phenolic antioxidants derived from aloe vera rind by-products. The procedure involved the application of ultrasound-assisted extraction (UAE) in combination with deep eutectic solvents (DESs). Eleven different DESs and three conventional solvents were employed as extraction media for polyphenolic compounds. Choline chloride-citric acid (ChCl-CA) was selected as the most suitable extractant, considering its extraction efficiency in relation to the total phenolic content. The operating conditions of UAE were optimized and modeled by the use of response surface methodology in order to maximize the yield of total phenolics and antioxidant capacity. The optimal operational parameters for the UAE procedure were determined to be 16.5 min, 74% (/) DES in water, and a solvent-to-solid ratio equal to 192. HPLC analysis, which was performed on the optimum extract, revealed significant levels of phenolics present in the aloe rind. Efficient recovery of the extracted antioxidants was obtained by the use of solid-phase extraction (SPE) and polyamide cartridges. The ChCl-CA DES exhibited excellent recycling capability with a yield of over 90% through SPE. Finally, the greenness of the method was evaluated using the green AGREE and AGREEprep metrics. The results highlighted the sustainability and the greenness of the proposed extraction procedure for the aloe by-product.

In this study, aloe emodin and β-d-glucose pentaacetate were added into potato starch/polyvinyl alcohol for the construction of colorimetric/fluorescent dual-pass intelligent response labels. Inspired by the lotus leaf structure, retained the advantages of the label itself and solved the hydrophilic problem of the label, and further developed a multi-functional dual-channel smart label with hydrophobicity and self-adhesion. The water contact angle of the prepared T-AEB label was 120.

Antimicrobial resistance is recognized as a threat to healthcare systems worldwide and consequently, discovery and development of new antimicrobials is a top priority. Natural products and their derivatives have historically been an excellent source of antimicrobials. In this context, anti-bacterial activity of synthesized natural product derivative, Rheinal, was assessed against a panel of Gram-positive and Gram-negative bacterial pathogens where it exhibited potent bactericidal activity against S.

Introduction Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia resulting from defects in insulin secretion, insulin action, or both. Among its complications, diabetic foot ulcers (DFUs) pose a significant healthcare challenge which result from impaired healing and infection risks, demanding better therapies. The aloe vera extract promotes wound healing by enhancing tissue regeneration and offering antimicrobial effects.

Background: Qualitative methods are essential for providing an in-depth understanding of "why" and "how" evidence-based interventions are successfully implemented-a key area of implementation science (IS) research. A systematic synthesis of the applications of qualitative methods is critical for understanding how qualitative methods have been used to date and identifying areas of innovation and optimization. This scoping review explores which qualitative data collection and analytic methods are used in IS research, what and how frameworks and theories are leveraged using qualitative methods, and which implementation issues are explored with qualitative implementation research.

Temozolomide (TMZ) is the frontline alkylating agent in melanoma cancer treatment but has a narrow therapeutic index due to its hemotoxicity. Targeting Wnt/β-catenin signaling could enhance the effectiveness of alkylating drugs and offer a promising approach to improve chemosensitivity. Nevertheless, developing a satisfactory method to efficiently inhibit Wnt/β-catenin for synergistic combination therapy remains an unmet goal.
