Background: Acetaminophen (APAP) overdose, common during pandemics like COVID-19, causes liver injury through oxidative stress. Ginger, known for its antioxidant properties, is suggested as a potential natural remedy. Objective: This study aimed to evaluate the therapeutic and prophylactic efficacy of ethanol ginger extract (GE) suspension (GS) on APAP-induced hepatotoxicity dyslipidemia in rats. Methods: Rats were assigned ten groups: control group, dimethyl sulfoxide groups receiving either GE or GS (150 mg/kg) two weeks. A group given single high dose APAP (2500 mg/kg), pre-treated with before APAP, three repeated doses (500 co-administrated along over Results: administration at regimens significantly impaired function, defenses, lipid metabolism. These disruptions included reduced levels markers such glutathione (GSH), catalase (CAT), superoxide dismutase (SOD), S-transferase (GST), reductase (GR), peroxidase (GPx), glucose-6-phosphate dehydrogenase (G6PDH). Lipid metabolism alterations evident from increased triacylglycerols (TAGs), total cholesterol (T-chol), low-density lipoprotein (LDL-chol), alongside decreased high-density (HDL-chol). The resulted severe damage, indicated by elevated malondialdehyde (MDA), alanine aminotransferase (ALT), alkaline phosphatase (ALP), altered protein fractions. Both treatments alleviated these changes, particularly MDA, ALT, GPx, LDL-chol levels. demonstrated superior protective effects compared GS, restoring GSH, ALP, CAT, SOD, GST, GR, G6PDH, HDL-chol, albumin alpha-1 globulins. In contrast, showed slightly greater reducing TAGs T-chol Conclusions: Ginger extracts offer significant protection against damage dyslipidemia, providing more pronounced effects.

The paper proposes a strategy for the accelerated deposition of biomimetic organomineral layers on surface dental enamel, utilizing di/tetrahydroquinolinediol (hydroxyquinoline) polymerized in presence nanocrystalline hydroxyapatite (nano-cHAp). mechanisms underlying formation coatings were elucidated through combination structural, microstructural, and spectroscopic analytical methods, including synchrotron infrared nanoimaging. Additionally, antimicrobial effects these investigated. It has been demonstrated that an layer, based dihydroxyquinoline, natural enamel leads to agglomeration orientation nanocrystals within coating. This process enables layer replicate mechanical properties resulting microhardness value closely resembles enamel. Using s-SNOM, it established possesses morphological structure poly(2,2,4-trimethyl-1,2-dihydroquinoline-6,7-diol (TMDHQ))/nano-cHAp composite film, which is homogeneously distributed tightly packed surface. Furthermore, coating formed from polydihydroxyquinoline exhibits inhibitory activity against colonies Streptococcus spp. developed technology layers, exhibit simultaneous antibacterial mineralizing effects, holds significant potential future clinical applications.
