In the present study, the toxicity and physiological disorders of the essential oil isolated from flowers were assessed against one of the main insect pests of mulberry, Walker, announcing one of the safe and effective alternatives to synthetic pesticides. The LC (lethal concentration to kill 50% of tested insects) values of the oral and fumigant bioassays of essential oil were 1.204 % W/V and 3.343 μL/L air, respectively. The essential oil rich in camphor, artemisia ketone, β-selinene, pinocarvone, 1,8-cineole, and α-pinene, caused a significant reduction in digestive and detoxifying enzyme activity of larvae. The contents of protein, glucose, and triglyceride were also reduced in the treated larvae by oral and fumigant treatments. The immune system in treated larvae was weakened after both oral and fumigation applications compared to the control groups. Histological studies on the midgut and ovaries showed that essential oil caused an obvious change in the distribution of the principal cells of tissues and reduction in yolk spheres in oocytes. Therefore, it is suggested that the essential oil from flowers, with wide-range bio-effects on , be used as an available, safe, effective insecticide in the protection of mulberry.

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.
