Background: Safflower thrives in dry environments but faces difficulties with flowering in wet and rainy summers. Flavonoids play a role in flower development and can potentially alleviate these challenges. Furthermore, the FLOWERING LOCUS T (FT) family of phosphatidylethanolamine-binding protein (PEBP) genes play a crucial role in the photoperiodic flowering pathway.

Porphyrinic hydrogen-bonded organic frameworks (porph-HOFs) have emerged as highly promising materials in the realm of photocatalysis due to their remarkable attributes, including low density, high surface area, efficient visible light absorption, and notable chemical stability. However, the rapid recombination of photogenerated charges remains a significant concern. In this work, a novel HOF-based photocatalyst, PFC-72/TiO was successfully designed with visible light response and high electron transfer capability.

The current study aimed to generate a sulfhydryl-modified β-cyclodextrin-silymarin complex (sulfhydryl-modified β-CD-SMN complex) and to evaluate the enchantment in solubility, permeability, and bioavailability of a model BCS Class IV drug silymarin (SMN). For this purpose, sulfhydryl-modified β-CD was synthesized by replacing all primary and secondary -OH groups at the β-CD backbone with sulfhydryl groups via a novel microwave-assisted technique. Afterward, sulfhydryl-modified β-CD was complexed with silymarin and characterized by FTIR and H NMR spectroscopy.

In an effort to prepare a modern polysaccharide-based dressing for sustained/prolonged delivery of the antibacterial agent to prevent and control skin wound infection, ciprofloxacin (CP)-loaded sodium alginate (SA)-chitosan (CS) nanoparticles (NPs) were incorporated into novel arabinoxylan (AX)-pectin (PC) blended polymeric films by solvent casting. The CP-NPs were prepared by a two-step ionic interaction method with < 300 nm size, about 25 mV zeta potential, 74% CP-loading efficiency, and approximately round shape. The CP-NPs were incorporated in optimized AX-PC polymeric film prepared by using 2% AX and 2% PC with a plasticizer (2% glycerol) and then these films were characterized for suitability as a film dressing.

Article Synopsis
  • - The study compares the yield and properties of peppermint essential oil (EO) extracted using hydro-distillation (HD) and supercritical fluid extraction (SCFE) methods, finding a higher yield for HD (0.20%) compared to SCFE (0.13%).
  • - Chemical analysis showed that menthol was the main component in both extraction methods, but SCFE-EO exhibited stronger antioxidant and antimicrobial activities than HD-EO, specifically with significant free radical inhibition and larger inhibition zones against certain bacteria.
  • - Overall, SCFE is suggested to be a more effective method for producing high-quality peppermint EO, making it a promising candidate for developing nutra-pharmaceutical products.

In this study, UV-vis spectroscopy was employed to investigate the interaction between formylphenoxyacetic acid (FPAA) and its derivatives (chalcone and flavones) with ionic surfactants (SDS, CTAB, and DTAB) in different physiological environments. Changes in the physiochemical properties of FPAA chalcone and flavones including binding constants, partitioning constants, and Gibbs free energy were observed which were influenced by the presence of ionic surfactants computed using mathematical models. The solubilization of the targeted compounds in the ionic surfactants was determined through the binding constant (Kb).
