Significant accumulation of systemically administered CCR nanoparticles was observed in the CCl4-induced fibrotic liver, an effect likely mediated by the specific recognition and binding of these nanoparticles to fibronectin and CD44 on activated hepatic stellate cells. Vismodegib-incorporated CCR nanoparticles not only damaged the Golgi apparatus, impacting its function, but also obstructed the hedgehog signaling pathway, resulting in a considerable decrease in HSC activation and extracellular matrix secretion, demonstrably in both in vitro and in vivo studies. Importantly, the use of vismodegib-containing CCR nanoparticles effectively reduced the fibrogenic cellular activity in the liver of CCl4-treated mice, with no noticeable toxic side effects. This multifunctional nanoparticle system, based on these findings, efficiently delivers therapeutic agents to the Golgi apparatus of activated hepatic stellate cells, presenting a potential treatment for liver fibrosis with a reduced risk of adverse effects.

The metabolic derangement of hepatocytes within non-alcoholic fatty liver disease (NAFLD) culminates in iron buildup, which catalyzes Fenton reaction-induced ferroptosis and a progression of liver disease. The elimination of the iron pool, to prevent Fenton reactions and subsequent NAFLD development, is of paramount importance, though its accomplishment is exceptionally challenging. Within the context of NAFLD, our research uncovers the previously undocumented ability of free heme in the iron pool to catalyze the hydrogenation of H2O2/OH, effectively inhibiting the heme-based Fenton reaction. This discovery has led to the development of a novel hepatocyte-targeted hydrogen delivery system (MSN-Glu), achieved by modifying magnesium silicide nanosheets (MSN) with N-(3-triethoxysilylpropyl) gluconamide, and thus breaking the vicious cycle of liver disease fostered by heme. The MSN-Glu nanomedicine, having demonstrated a high hydrogen delivery capacity, sustained release, and hepatocyte targeting, dramatically ameliorates liver metabolic function in a NAFLD mouse model. This positive effect is achieved by reducing oxidative stress, preventing ferroptosis, and facilitating the removal of iron deposits in hepatocytes, fundamentally supporting NAFLD prevention. NAFLD disease mechanisms and hydrogen medicine offer the foundation for a proposed prevention strategy that will inspire prevention efforts for inflammation-related diseases.

Clinical treatment faces a constant threat from multidrug-resistant bacteria, a primary cause of wound infections in post-operative and open trauma settings. Conventional antibiotic antimicrobial therapy often struggles with drug resistance, a challenge effectively overcome by the promising antimicrobial treatment of photothermal therapy. This study describes a functionalized cuttlefish ink nanoparticle (CINP) with deep tissue penetration for treating wound infections using both photothermal and immunological strategies. CINP is adorned with a zwitterionic polymer (ZP), a sulfobetaine methacrylate-methacrylate copolymer, to form composite CINP@ZP nanoparticles. Methicillin-resistant Staphylococcus aureus (MRSA) and Escherichia coli (E. coli) undergo photothermal destruction when exposed to natural CINP. Not only do they stimulate the activity of immune cells (coli), but also they activate macrophages' innate immune response, boosting their antimicrobial capabilities. Deeply infected wound environments are penetrable by nanoparticles due to the ZP coating on CINP. Moreover, CINP@ZP is seamlessly incorporated into the temperature-sensitive Pluronic F127 gel, forming CINP@ZP-F127. Mice wound models, inoculated with MRSA and E. coli, showed notable antibacterial effects of CINP@ZP-F127 following in situ gel application. By merging photothermal therapy with immunotherapy, this approach enhances the delivery of nanoparticles to the deep recesses of infective wounds, thereby effectively eliminating the infections.

The task of managing a healed perineal wound after chemoradiotherapy and abdominoperineal resection (APR) proves difficult for both surgeons and patients. While prior investigations have highlighted the superiority of trunk-based flaps, including the vertical rectus abdominis myocutaneous (VRAM) flap, over primary closure and thigh-based flaps, a direct comparison with gluteal fasciocutaneous flaps remains absent. This study analyzes postoperative complications resulting from a variety of perineal flap closure techniques employed in APR and pelvic exenteration defect repair procedures.
This retrospective review focused on postoperative complications in patients undergoing either abdominoperineal resection (APR) or pelvic exenteration procedures, encompassing the time period from April 2008 to September 2020. A comparative evaluation was undertaken to assess the effectiveness of flap closure techniques, including VRAM, unilateral IGAP, and bilateral BIGAP inferior gluteal artery perforator fasciocutaneous flaps.
Of the 116 patients in this study, the fasciocutaneous (BIGAP/IGAP) flap reconstruction procedure was carried out in the majority (69 patients, 59.6%), followed by VRAM in 47 patients (40.5%). No noteworthy differences were detected in group patient characteristics encompassing demographics, comorbidities, body mass index, or cancer stage. The BIGAP/IGAP and VRAM groups displayed no noteworthy distinctions in terms of minor complications (57% versus 49%, p=0.426) or major complications (45% versus 36%, p=0.351), including major and minor perineal wounds.
Earlier studies have highlighted the benefits of flap closure over primary closure in patients undergoing APR and neoadjuvant radiation, however, there's no consensus on the type of flap that yields the best postoperative morbidity profile.
