This study examined the relationship between job satisfaction and unethical pro‐organizational behaviours (UPB) by testing a moderated mediation model that focused on how employees' belongingness mediates the relationship between job satisfaction and UPB and how corporate ethical values moderate this mediated relationship. Our investigation included 369 employees from different organizations in Southeast China. The regression analysis revealed that job satisfaction positively influences UPB through belongingness. In addition, a moderated regression analysis indicated that low corporate ethical values strengthen not only the effect of belongingness on UPB but also the indirect effect of job satisfaction on UPB. These findings deepen our understanding of UPB by showing that individuals with a high level of job satisfaction are more likely to engage in UPB through belongingness when corporate ethical values are low. Finally, the theoretical and managerial implications of these results are discussed. [ABSTRACT FROM AUTHOR]

Abstract: In this work, a systematic theoretical investigation on a series of dimeric complexes formed between MH2 and HX has been carried out by employing correlated ab initio methods. It was shown that besides dihydrogen bonds, there also exists novel noncovalent X⋯H interactions between the two molecules, which have similar characteristics to traditional halogen bonds. Upon complexation, the Hend to elongate in all cases, concomitant with red-shifts of the Hing frequencies. X⋯H interaction energies, calculated at the MP2/aug-cc-pvtz level, range from −2.11 to −11.78kJ/mol; the interactions are much weaker than corresponding dihydrogen bonds. The major stabilization source of dihydrogen and halogen bonds arises from the electrostatic force, while charge-transfer force plays a minor role in the formation of the complexes. AIM analyses further confirm the presence of X⋯H interactions in the systems, and the electron density at bond critical points correlates fairly well with the interaction energy.

The development of the embryo sac is an important factor affecting seed setting in rice. Numerous genes associated with embryo sac (ES) development have been identified in plants. However, the function of the DEAD-box RNA helicase family genes on ES is poorly known in rice. Here, we characterized a rice DEAD-box protein, OsRH52A, which was localized in the nucleus and cytoplasm and highly expressed in the floral organs in rice. The knockout mutant, rh52a, displayed partial ES sterility, including degenerated ES (21.0%) and the presence of double-female-gametophyte (DFG) structure (11.8%). The DFG developed from two functional megaspores (FM) near the chalazal end in one ovule, and 3.4% of DFG could fertilize via the sac near the micropylar pole in rh52a. OsRH52A was found to interact with OsMFS1 and ZIP4, both of which play a role in homologous recombination in rice meiosis. RNA-seq identified 234 down-regulated differentially expressed genes (DEGs) associated with reproductive development, including the two genes, OsMSP1 and HSA1b, required for female germline cell specification. Taken together, our study demonstrated that OsRH52A is essential for the development of the embryo sac and provided cytological evidence regarding the formation of DFG., (© The Author(s) 2024.

As a gamma-aminobutyric acid type A receptor agonist sevoflurane is a common general anesthetic used in anesthesia and affects the neural development in offspring. We hypothesized that sevoflurane could regulate interneurons via the neuregulin-1-epidermal growth factor receptor-4 (NRG1-ErbB4) pathway in the entorhinal cortex (ECT) of the middle pregnancy. Six female rats in middle pregnancy (14.5 days of pregnancy) were randomly and equally divided into sevoflurane (SeV) and control groups. The rats in the SeV group were exposed to 4% sevoflurane for 3 hours. The expression levels of NRG1 and ErbB4, parvalbumin (PV) and glutamic acid decarboxylase (GAD67), and N -methyl-D-aspartate receptor subunit 2A (NR2A) and subunit 2B (NR2B) in offspring were examined through immunohistochemistry. The pyramidal neurons in the ECT were examined via Golgi staining. The levels of NRG1 and ErbB4 were significantly decreased ( P < 0.01) and the levels of PV and GAD67 (interneurons) were found to be decreased in the SeV group ( P < 0.01). The level of NR2B was found to be increased while the level of NR2A being decreased in the SeV group ( P < 0.01). The development of pyramidal neurons was abnormal in the SeV group ( P < 0.05). Conclusively, prenatal sevoflurane exposure could lead to the disturbance of the interneurons by activating the NRG1-ErbB4 pathway and subsequently result in abnormal development of pyramidal neurons in middle pregnancy. Prenatal sevoflurane exposure in middle pregnancy could be potentially harmful to the neural development of rat offspring. This study may reveal a novel pathway in the influence mechanism of sevoflurane on rat offspring., Competing Interests: The authors declare no conflict of interest., (© 2021 The Author(s).
