Physicochemical, steric, and energetic characterization of kaolinite based silicate nano-sheets as potential adsorbents for safranin basic dye: effect of exfoliation reagent and techniques.

Kaolinite was subjected to advanced exfoliation processes to form separated nano-silicate sheets (EXK) with enhanced physicochemical properties as adsorbents. This involved the incorporation of different exfoliating agents, urea (U/EXK), KNO (N/EXK), and CTAB (C/EXK), highlighting their impacts on their textural and surficial properties as adsorbents for safranin dye. The applied characterization techniques confirmed the higher exfoliating degree of C/EXK, followed by N/EXK and U/EXK.

Anti-inflammatory effect of trans-anethol in a rat model of myocardial ischemia-reperfusion injury.

Unlabelled: Myocardial ischemia‑reperfusion injury (MI/R) is considered a main risk factor for global cardiac mortality and morbidity, for which no effective treatment exists. Both inflammation and epigenetic regulation play a pivotal role in the early stage of MI/R. The present study aimed at investigating the prospective anti-inflammatory role of trans-anethole (TNA) in targeting MI/R and its related mechanism in upregulating the expression of the inflammatory and cardiac-related gene (VAV3), and its epigenetic regulators (lncRNA-JRKL-AS1 and miR-1298) that were retrieved from in-silico data analysis in an ischemia/reperfusion (I/R) rat model.

Cyclosporine Ameliorates Silica-Induced Autoimmune Hepatitis in Rat Model by Altering the Expression of Toll-Like Receptor-4, Interleukin-2, and Tumor Necrosis Factor-α.

Background: Autoimmune hepatitis (AIH) is an inflammatory liver disease that is characterized histologically by interface hepatitis, biochemically by elevated transaminase levels, and serologically by the presence of autoantibodies. Toll-like receptor (TLR)-4 is a TLR family member that, upon activation in hepatocytes, initiates a cascade of events. Interleukin-2 (IL-2) and tumour necrosis factor α (TNF-α) are potent inflammatory cytokines secreted in AIH, playing an important role in the early development of inflammation and hepatocyte damage.
