ABSTRACT Colistin is renowned as a last‐resort antibiotic due to the emergence of multidrug‐resistant pathogens. However, its potential toxicity significantly hampers clinical utilization. Melatonin, chemically known N ‐acetyl‐5‐hydroxytryptamine, an endogenous hormone produced by pineal gland and possesses diverse biological functions. protective role melatonin in alleviating antibiotic‐induced intestinal inflammation remains unknown. Herein, we reveal that colistin stimulation markedly elevates inflammatory levels compromises gut barrier. In contrast, pretreatment with safeguards mice against mucosal damage. Microbial diversity analysis indicates supplementation prevents reduction abundance Erysipelotrichales Bifidobacteriales , well increase Desulfovibrionales abundance, following exposure. Remarkably, short‐chain fatty acids (SCFAs) shows propanoic acid contributes effect on colistin‐induced inflammation. Furthermore, protection effects LPS‐induced cellular RAW 264.7 cells are confirmed. Mechanistic investigations suggest intervention can repress activation TLR4 signal downstream NF‐κB MAPK signaling pathways, thereby mitigating toxic colistin. Our work highlights unappreciated preventing detrimental health suggests combined therapeutic strategy effectively manage infectious diseases.

Abstract Photothermal therapy (PTT) has garnered significant attention in recent years, but the standalone application of PTT still faces limitations that hinder its ability to achieve optimal therapeutic outcomes. Nitric oxide (NO), being one most extensively studied gaseous molecules, presents itself as a promising complementary candidate for PTT. In response, various nanosystems have been developed enable simultaneous utilization and NO‐mediated gas (GT), with integration photothermal agents (PTAs) thermally‐sensitive NO donors prevailing approach. This combination seeks leverage synergistic effects GT while mitigating potential risks associated toxicity through use single laser irradiation. Furthermore, additional internal or external stimuli employed trigger release when combined different types PTAs, thereby further enhancing efficacy. comprehensive review aims summarize advancements gas‐assisted cancer treatment. It commences by providing an overview precursors, including those sensitive photothermal, light, ultrasound, reactive oxygen species, glutathione. These precursors are discussed context dual‐modal PTT/GT. Subsequently, incorporation other treatment modalities such chemotherapy (CHT), photodynamic (PDT), alkyl radical therapy, radiation immunotherapy (IT) creation triple‐modal nanoplatforms is presented. The explores tetra‐modal therapies, PTT/GT/CHT/PDT, PTT/GT/CHT/chemodynamic (CDT), PTT/GT/PDT/IT, PTT/GT/starvation (ST)/IT, PTT/GT/Ca 2+ overload/IT, PTT/GT/ferroptosis (FT)/IT, PTT/GT/CDT/IT.

Immunotherapy had demonstrated inspiring effects in tumor treatment, but only a minority of people could benefit owing to the hypoxic and immune-suppressed microenvironment (TME). Therefore, there was an urgent need for strategy that relieve hypoxia increase infiltration lymphocytes simultaneously. In this study, novel acidity-responsive nanoscale ultrasound contrast agent (L-Arg@PTX nanodroplets) constructed co-deliver paclitaxel (PTX) L-arginine (L-Arg) using homogenization/emulsification method. The L-Arg@PTX nanodroplets with uniform size about 300 nm high drug loading efficiency displayed good diagnostic imaging capability, improved aggregation achieved ultrasound-triggered release, which prevent premature leakage drugs thus improve biosafety. More critically, combination targeted microbubble destruction (UTMD) cellular reactive oxygen species (ROS), exerted oxidizing effect converted L-Arg into nitric oxide (NO), alleviating hypoxia, sensitizing chemotherapy increasing CD8 + cytotoxic T (CTLs) infiltration. Combined chemotherapeutic PTX-induced immunogenic cell death (ICD), promising enhance immunotherapy synergistically realize powerful treatment effect. Taken together, very hopeful vehicle integrated delivery, imaging, chemoimmunotherapy.

Abstract Cancer metastasis poses significant challenges in current clinical therapy. Osthole (OST) has demonstrated efficacy treating cervical cancer and inhibiting metastasis. Despite these positive results, its limited solubility, poor oral absorption, low bioavailability, photosensitivity hinder application. To address this limitation, a glutathione (GSH)‐responded nano‐herb delivery system (HA/MOS@OST&L‐Arg nanoparticles, HMOA NPs) is devised for the targeted of OST with cascade‐activatable nitric oxide (NO) release. The NPs engineered utilizing enhanced permeability retention (EPR) effects active targeting mediated by hyaluronic acid (HA) binding to glycoprotein CD44. cargoes, including L‐Arginine (L‐Arg), are released rapidly due degradation GSH‐responsive mesoporous organic silica (MOS).
