However, the insoluble nature of FePP restricts its intestinal absorption, thereby diminishing its efficacy. Liposomes can enhance the transmembrane absorption of encapsulated ingredients but encounter difficulties when encapsulating insoluble compounds. In this study, it was initially attempted to boost FePP solubility by reducing its particle size. Nevertheless, nanoscale FePP (N-FePP) exhibited a strong tendency to aggregate. To address this, an ultrasound-assisted carboxymethyl cellulose modification was innovatively proposed. This method effectively prevented N-FePP aggregation by increasing its charge density from -23 mV to -40 mV and decreasing surface tension of the N-FePP suspension from 71.1 mN/m to 43.8 mN/m. Consequently, the modified N-FePP (MN-FePP), with a particle size of 237 nm and excellent dispersion, was successfully obtained. The encapsulation efficiency of MN-FePP in liposomes (MN-FePP-Lip) was significantly enhanced compared to that of N-FePP (74.9 % vs. 27.8 %). Furthermore, in comparation with the unencapsulated MN-FePP, MN-FePP-Lip exhibited increased cellular absorption efficiency (intracellular iron concentrations of 171.54 μmol/L vs. 115.24 μmol/L) and total antioxidant levels (9.04 U/mg prot vs. 7.28 U/mg prot) in cells.

This study investigates vegetable tanning with oak bark extracts obtained using eco-friendly Ultrasound-Assisted Extraction (UAE), providing a straightforward analytical approach for a better understanding of the molecular mechanisms by which these extracts stabilise the collagen-tannin interactions. Aqueous extraction of oak bark polyphenols, achieved employing a continuous UAE process, scalable for industrial use, was also boosted using very low concentrations of NaOH (0.1 to 0.5 %) or 0.25 % sulfite/bisulfite. Collagen-tannin matrices were characterized using micro-differential scanning calorimetry (micro-DSC), ATR-FTIR spectroscopy, NMR MOUSE, and thermal microscopy. Key results show that aqueous and low-alkali bark extracts stabilise collagen mainly through hydrogen bonding. Alkali and sulfonated extracts create a mixed network of hydrogen and covalent bonds, likely linked to lignin derivatives. Micro-DSC analysis revealed the highest increase in denaturation temperature, up to 11-14 °C, and a narrowing of transition peaks in collagen matrices treated with 0.2 % and 0.5 % NaOH extracts. ATR-FTIR confirmed the formation of ester bonds. NMR MOUSE results showed increased chain packing and water exclusion, linking to enhanced physicomechanical properties. Leather produced using the oak bark extracts showed hydro-thermal and mechanical resistance and structural homogeneity that match those of conventional vegetable-tanned leathers.

Intra-articular (IA) injection of steroids has been approved and used for the management of pain and further loss of cartilage in patients. However, meta-analysis suggests that IA-usage of high-dose steroids was associated with osteonecrosis, subchondral insufficiency fracture, and rapid joint destruction with bone loss. Upregulation of lysophosphatidylcholine acyltransferase 3 (LPCAT3) has been demonstrated in OA and was correlated with the severity of the disease. The current study unveils that LPCAT3 plays a critical role in the cellular efflux of a steroidal drug (methylprednisolone; MPD) through post-translational regulation and stabilization of a steroid efflux protein, ATP-Binding Cassette Subfamily A Member 1 (ABCA1). Gene silencing of LPCAT3 downregulates ABCA1 protein through ubiquitination and degradation in the chondrocytes. This loss of ABCA1 favors increased cellular retention of MPD, thereby reducing the minimal effective dosage of MPD and promoting the anti-inflammatory benefits of MPD. Conversely, the Liver X Receptor (LXR) agonist (T0901317) completely reversed the LPCAT3-induced alterations of ABCA1 and steroid retention in the cells. Consistent with the in vitro studies, IA administration of LPCAT3 siRNA liposomes downregulates ABCA1 in the synovium and potentiates the therapeutic benefits of MPD at much smaller doses in the Destabilization of the Medial Meniscus (DMM) surgery-induced OA in mice. This study reveals a previously unrecognized role of ABCA1 in the MPD steroidal drug-efflux.
