The current investigation was performed for the detailed analysis of protective effect of biofabricate berberine coated nano‑silver ameliorate (BBR-AgNPs) on acetaminophen (APAP) induced hepato-renal damages in diabetic rats by blood biochemistry , tissue biochemistry , histopathological and immunohistochemical analysis. The spherical shaped BBR-AgNPs were synthesized by the Biofabrication technique and its physico-chemical characterizations done by different spectroscopic (UV–vis spectrophotometer , XRD spectroscopy, FTIR spectroscopy EDAX & DLS analyses) and microscopic (FE-SEM) techniques. The diabetic developed rats were administrated with APAP (2.0 g/5 mL/kg) and scrutinize its hepato-renal injuries. The synthesized BBR-AgNPs (75 mg/kg p.o) was administrated orally to the APAP-induced diabetic rats. The result of biochemical markers and lipid peroxidation were significantly (P ˂ 0.05) increased in APAP-induced diabetic rats but decreased the level of antioxidants (P ˂ 0.05), which results obtained in liver and kidney compared to the control group. Immunohistochemical studies result showed that the APAP-induced diabetic rats expressed a high immunoreactivity of nuclear transcription factor (NF-kB). Whereas, the acetaminophen-induced diabetic rats were treated with BBR-AgNPs renovated the changes in the above parameters analyzed. The results of the study clearly indicated that the BBR-AgNPs possess the antioxidant properties as well as anti-diabetic effects, furthermore, the acetaminophen-induced liver and kidney damage was probably inhibited by the inhibition of proinflammatory factor & NF-kB factors.

Consumption of tea residues dietary fiber (TRDF) contributed to the relief of hyperglycemia symptoms in type 2 diabetes (T2D). Given the properties of TRDF abundant in bound polyphenols, the research intended to evaluate the effect of the presence or absence of bound polyphenols in TRDF on the improvement of diabetic complications (liver and kidney injury, metabolic disorders) in T2D rats induced by high-fat diet and streptozocin injection. Our results revealed that the presence of bound polyphenols in TRDF was remarkably beneficial for the amelioration of liver and kidney damage caused by T2D, which was supported by significant differences in activities of serum glutamic oxaloacetic transaminase (AST) and glutamic-pyruvic transaminase (ALT), contents of inflammatory factors in liver and kidney, the levels of kidney oxidative stress, as well as histopathological status between TRDF and bound polyphenols removed-TRDF (TRDF-DF) groups. In addition, metabolomic analysis revealed that TRDF interventions could increase the levels of metabolites such as S-Adenosylmethionine, L-Homophenylalanine and Riboflavin, as well as differ in the regulation of the metabolic pathways including arachidonic acid metabolism and cysteine and methionine metabolism as compared to TRDF-DF without bound polyphenols. These results suggested that bound polyphenols ensured the health-promoting effects for T2D complications of TRDF.

Introduction Polydatin is a biologically active compound found in mulberries, grapes, and Polygonum cuspidatum , and it has uric acid-lowering effects. However, its urate-lowering effects and the molecular mechanisms underlying its function require further study. Methods In this study, a hyperuricemic rat model was established to assess the effects of polydatin on uric acid levels. The body weight, serum biochemical indicators, and histopathological parameters of the rats were evaluated. A UHPLC-Q-Exactive Orbitrap mass spectrometry-based metabolomics approach was applied to explore the potential mechanisms of action after polydatin treatment. Results The results showed a trend of recovery in biochemical indicators after polydatin administration. In addition, polydatin could alleviate damage to the liver and kidneys. Untargeted metabolomics analysis revealed clear differences between hyperuricemic rats and the control group. Fourteen potential biomarkers were identified in the model group using principal component analysis and orthogonal partial least squares discriminant analysis. These differential metabolites are involved in amino acid, lipid, and energy metabolism. Of all the metabolites, the levels of L -phenylalanine, L -leucine, O -butanoylcarnitine, and dihydroxyacetone phosphate decreased, and the levels of L -tyrosine, sphinganine, and phytosphingosine significantly increased in hyperuricemic rats. After the administration of polydatin, the 14 differential metabolites could be inverted to varying degrees by regulating the perturbed metabolic pathway. Conclusion This study has the potential to enhance our understanding of the mechanisms of hyperuricemia and demonstrate that polydatin is a promising potential adjuvant for lowering uric acid levels and alleviating hyperuricemia-related diseases.

Ganoderma lucidum spore oil (GLSO) has been long practiced and widely recognized as a healthy food composite performing potential anticancer and antioxidant activity. However, its further application might be limited by the native poorly soluble and instable properties. Herein, size-tunable GLSO nanosystems have been designed and tailored to three sizes of particles at 20 nm, 40 nm and 80 nm by high-pressure homogenization, for achieving robust therapeutic effect against cancer cells. As expected, toxicity of biocompatible different-sized [email protected] on MGC803 cancer cells significantly enhanced, thanks to the improved cellular uptake and retention efficacy of [email protected] In addition, middle-sized 40 [email protected] performed superior permeability across Caco-2 intestinal absorption barrier to improve internalized quantity of GLSO. More importantly, [email protected] could effectively prevent cell migration and invasion, simultaneously activating caspase activity to trigger cell death. Interestingly, middle size of 40 [email protected] performed superior accumulation efficacy in cells. Ultimately, 40 [email protected] showed potent suppression effect on tumors in vivo , effectively reversing liver and kidney damage induced by cancer, which was accompanied with no obvious toxicity and side effects during treatment. Therefore, this study not only provides a simple method for preparation of GLSO-like traditionally functional composite by high-pressure homogenization, but also sheds light on the application in future clinical cancer therapy.

Cantharidin (CTD) has been widely used to treat hepatocellular carcinoma (HCC) in clinical practice. However, the current CTD preparations may induce hepatic and renal damage due to their non-specific distribution. Therefore, redox-sensitive polymer Pluronic F127-disulfide bond-poly(D,L-lactide) (F127-SS-PDLA) and active targeting polymer F127-glycyrrhetinic acid (F127-GA) were synthesized to prepare mixed micelles (GA/F127-SS-PDLA/CTD) for effective delivery of CTD. Fourier transform infrared (FTIR) spectroscopy and 1H nuclear magnetic resonance (1H-NMR) spectroscopy were used to verify the successful synthesis of F127-SS-PDLA and F127-GA. During the preparation, this study was the first to screen the density of GA by cellular uptake assay. The results indicated that mixed micelles with 10% and 15% F127-GA (weight fraction) exhibited superior cellular uptake in comparison to micelles with 5% and 20% F127-GA. GA/F127-SS-PDLA/CTD micelles prepared by thin film hydration method demonstrated excellent drug loading capacity for CTD (16.12 ± 0.11%). The particle size and zeta potential of GA/F127-SS-PDLA/CTD micelles were 85.17 ± 1.24 nm and −11.71 ± 0.86 mV, respectively. Hemolysis and stability assay showed that the mixed micelles had good blood compatibility and could remain stable for 30 days at 4 °C. The redox-sensitivity of GA/F127-SS-PDLA/CTD micelles in vitro was verified under reducing conditions through dynamic light scattering (DLS) and an in vitro drug release experiment, which showed obvious particle size variation and rapid drug release ability. In cellular experiments, GA/F127-SS-PDLA/CTD micelles could induce superior cytotoxicity, apoptosis and intracellular reactive oxygen species (ROS) levels compared with free CTD, non-sensitive F127-PDLA/CTD micelles and redox-sensitive F127-SS-PDLA/CTD micelles. The cellular uptake ability of nile red-labeled GA/F127-SS-PDLA micelles, which was evaluated via fluorescent microscope and flow cytometry, indicated that the modification of GA significantly increased micelle uptake in HepG-2 cells. Consequently, GA/F127-SS-PDLA/CTD micelles could be considered as a satisfactory drug administration strategy in the treatment of HCC.
