Finally, differences and similarities between these nanocarriers are discussed, along with current and future applications that are warranted by their structures and properties.Preparing wound dressing with dual-delivery of antioxidant and antibacterial agents is highly desirable in clinical wound treatment. Herein, a series of coaxial nanofiber membranes loaded with antioxidant tea polyphenols (TP) in the core and antibacterial ε-poly (L-lysine) (ε-PL) in the shell layer were successfully fabricated by coaxial electrospinning. The physicochemical characterizations by transmission electron microscopy, inverted fluorescence microscopy and fourier transform infrared spectroscopy confirmed the formation of core-shell structure. The results of in vitro drug release indicated that ε-PL exhibited a fast release profile while TP released in a sustained manner, which is favorable to the achievement of quick bacteria inhibition in the initial phase as well as long-term antioxidant activity during wound healing. The antioxidant activity of coaxial nanofibers was found to be increased with the increment of TP content and incubation time. The antibacterial assays against Escherichia coli and Staphylococcus aureus demonstrated that the incorporation of ε-PL in the coaxial nanofibers led to strong antibacterial activity. Additionally, all the coaxial nanofibers possessed good cytocompatibility. Therefore, the prepared coaxial nanofibers simultaneously incorporated with ε-PL and TP are promising as potential wound dressing materials.Poor patient response and limited treatment modalities are the major challenges against combating triple-negative breast cancer (TNBC). The high related mortality urges for novel cancer therapeutics. Guanabenz acetate (GA) is an orphan antihypertensive drug with a short half-life. Re-purposing (GA) by developing a polymersome (PS)-based cancer nanomedicine is an innovative approach in treating TNBC. Formulation and optimization of GA-loaded PEGylated Polycaprolactone PS through different process variables (solvent selection, the order of addition, pH of the aqueous phase, and drug to polymer ratio) were achieved by the nanoprecipitation method. The in vitro cellular uptake, anti-cancer, and anti-metastatic activity of GA and GA-loaded PS were tested in MDA-MB 231(TNBC cell line) and MCF-7 cell line. Western blot analysis was performed to elucidate the molecular anti-cancer mechanism. Decitabine cost The in vivo biodistribution study and antitumor activity were investigated in the TNBC-xenograft model implanted in mice. Underof TNBC.
The ancient Chinese herbal formula Longdan Xiegan Tang (LXT, also called Gentiana Longdancao Decoction to Drain the Liver) treats insulin resistance- and inflammation-associated liver injuries in clinical practice.

To investigate the molecular mechanisms underlying LXT-elicited improvement of the liver injuries.

Male rats were co-treated with olanzapine (5mg/kg) and LXT extract (50 and 500mg/kg) for eight weeks. Blood parameters were determined enzymatically or by ELISA. Gene/protein expression was analyzed by Real-Time PCR, Western blot and/or immunohistochemistry.

LXT attenuated olanzapine-induced liver injury manifested by hyperactivities of plasma alanine aminotransferase and aspartate aminostransferase, hyperbilirubinemia and hypoalbuminemia. Furthermore, LXT improved hepatic insulin resistance that was indicated by hyperinsulinemia, the increased HOMA-IR index, and hepatic over-phosphorylation of Ser

Plectranthus vettiveroides (Jacob) N.P. Singh & B.D. Sharma is a traditional medicinal plant used in Siddha System of Medicine and its aromatic root is used to reduce the elevated blood pressure.

The aim of the present study was to study vasorelaxant property of the root essential oil nanoemulsion (EON) of P. vettiveroides.

The EON was formulated to enhance the solubility and bioavailability and characterized. The preliminary screening was performed by treating the EON with aortic rings pre-contracted with phenylephrine (1μM) and potassium chloride (80mM). The role of K⁺ channels in EON induced vasorelaxation was investigated by pre-incubating the aortic rings with different K⁺ channel inhibitors namely, glibenclamide (a non-specific ATP sensitive K⁺ channel blocker, 10μM), TEA (a Ca
⁺ activated non-selective K⁺ channel blocker, 10
M), 4-AP (a voltage-activated K⁺ channel blocker, 10
M) and barium chloride (inward rectifier K⁺ channel blocker, 1mM). The involvement of extracellular Ca
was perfot is concluded that the root essential oil of P. vettiveroides is possessing marked vasorelaxant property. The multiple mechanisms of action of the essential oil of P. vettiveroides make it a potential source of antihypertensive drug.Ferroptosis is an iron- and lipotoxicity-dependent regulated cell death that has been implicated in various diseases, such as cancer, neurodegeneration and stroke. The biosynthesis of phospholipids, coenzyme Q10, and glutathione, and the metabolism of iron, amino acids and polyunsaturated fatty acid, are tightly associated with cellular sensitivity to ferroptosis. Up to now, only limited drugs targeting ferroptosis have been documented and exploring novel effective ferroptosis-modulating compound is needed. Natural bioactive products are conventional resources for drug discovery, and some of them have been clinically used against cancers and neurodegenerative diseases as dietary supplements or pharmaceutic agents. Notably, increasing evidence demonstrates that natural compounds, such as saponins, flavonoids and isothiocyanates, can either induce or inhibit ferroptosis, further expanding their therapeutic potentials. In this review, we highlight current advances of the emerging molecular mechanisms and disease relevance of ferroptosis. We also systematically summarize the regulatory effects of natural phytochemicals on ferroptosis, and clearly indicate that saponins, terpenoids and alkaloids induce ROS- and ferritinophagy-dependent ferroptosis, whereas flavonoids and polyphenols modulate iron metabolism and nuclear factor erythroid 2-related factor 2 (NRF2) signaling to inhibit ferroptosis. Finally, we explore their clinical applications in ferroptosis-related diseases, which may facilitate the development of their dietary usages as nutraceuticals.
