We studied the effects of essential oil from oregano and clove and a mixture of lemon essential oil and a ginger extract on the antioxidant state of organs in intact and three experimental groups of Bulb mice. We found that the essential oil was an efficient in vivo bioantioxidant when mice were treated with it for 6 months even at very low doses, such as 300 ng/day. All essential oil studied inhibited lipid peroxidation (LPO) in the membranes of erythrocytes that resulted in increased membrane resistance to spontaneous hemolysis, decreased membrane microviscosity, maintenance of their structural integrity, and functional activity. The essential oil substantially decreased the LPO intensity in the liver and the brains of mice and increased the resistance of liver and brain lipids to oxidation and the activity of antioxidant enzymes in the liver. The most expressed bioantioxidant effect on erythrocytes was observed after clove oil treatment, whereas on the liver and brain, after treatment with a mixture of lemon essential oil and a ginger extract.

The application of 2D materials for detecting dissolved gas molecules is essential for identifying faults in oil-immersed transformers. This study investigates the adsorption properties of ZrCl monolayer (ML) and Pd-doped ZrCl ML with six gas molecules (CO, CO, CH, CH, CH, CH) in transformer oil using the density functional approach. The adsorption behaviour was analysed by calculating and comparing the structures, charge transfer and adsorption energies.

(peppermint oil) when used as a sensory additive in feed and in water for drinking for all animal species. The EFSA Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) concluded that that peppermint oil is safe for all animal species at the maximum use level of 12 mg/kg complete feed.

The RNase activity of MCPIP1 is essential for regulating cellular homeostasis, proliferation, and tumorigenesis. Our study elucidates the effects of downregulation of MCPIP1 expression and an RNase-inactivating mutation (D141N) on normal epithelial kidney cells, indicating that MCPIP1 expression is a key factor that suppresses neoplastic transformation. We observed that either expression downregulation or mutation of MCPIP1 significantly increased its clonogenicity and altered the expression of cancer stem cell (CSC) markers and factors involved in epithelial-to-mesenchymal transition (EMT).

The unique structure of chitosan-based micelles can be loaded with essential oil, so it is significant to study the modification of chitosan and the interactions between chitosan and essential oil, while molecular dynamics (MD) simulation and density functional theory (DFT) provide a solution. In this study, three kinds of amphiphilic chitosan derivatives (CSDs) were constructed by grafting of different hydrophilic and hydrophobic groups. Amphiphilic chitosan micelles loaded with Chinese fir essential oil (CFEO) were prepared by self-assembly.
