of support in managing anger expression.
The study revealed that in the COVID-19 pandemic the anxiety levels of the nurses were high and that the high anxiety level negatively affected the style of anger expression, but the nurses were successful in maintaining anger control. In line with these results, it is important that nurses develop effective coping strategies to reduce their anxiety levels and that they receive increased levels of support in managing anger expression.Acute liver injury (ALI) is a rapid pathological process that may cause severe liver disease and may even be life-threatening. During ALI, the function of males absent on the first (MOF) has not yet been elucidated. In this study, we unveiled the expression pattern of MOF during carbon tetrachloride (CCl4 )-induced ALI and role of MOF in the regulation of liver regeneration. In the process of ALI, MOF is significantly overexpressed in the liver injury area. Knockdown of Mof attenuated CCl4 -induced ALI, and promoted liver cell proliferation, hepatic stellate cell activation and aggregation to the injured area, and liver fibrosis. Simultaneously, overexpression of Mof aggravated liver dysfunction caused by ALI. By directly binding to the promoter, MOF suppressed the transcriptional activation of Igf1. Knockdown of Mof promotes the expression of Igf1 and activates the Insulin-like growth factor 1 signaling pathway in the liver. Through this pathway, Knockdown of Mof reduces CCl4 -induced ALI and promotes liver regeneration. Our results provide the first demonstration for MOF contributing to ALI. Further understanding of the role of MOF in ALI may lead to new therapeutic strategies for ALI.The period beginning with the signal for ovulation, when a fully-grown oocyte progresses through meiosis to become a mature egg that is fertilized and develops as a preimplantation embryo, is crucial for healthy development. The early preimplantation embryo is unusually sensitive to cell volume perturbations, with even moderate decreases in volume or dysregulation of volume-regulatory mechanisms resulting in developmental arrest. To prevent this, early embryos possess mechanisms of cell volume control that are apparently unique to them. These rely on the accumulation of glycine and betaine (N, N, N-trimethylglycine) as organic osmolytes-compounds that can provide intracellular osmotic support without the deleterious effects of inorganic ions. Preimplantation embryos also have the same mechanisms as somatic cells that mediate rapid responses to deviations in cell volume, which rely on inorganic ion transport. Both the unique, embryo-specific mechanisms that use glycine and betaine and the inorganic ion-dependent mechanisms undergo major changes during meiotic maturation and preimplantation development. The most profound changes occur immediately after ovulation is triggered. Before this, oocytes cannot regulate their volume, since they are strongly attached to their rigid extracellular matrix shell, the zona pellucida. After ovulation is triggered, the oocyte detaches from the zona pellucida and first becomes capable of independent volume regulation. A complex set of developmental changes in each cell volume-regulatory mechanism continues through egg maturation and preimplantation development. The unique cell volume-regulatory mechanisms in eggs and preimplantation embryos and the developmental changes they undergo appear critical for normal healthy embryo development.Calcified tissues have repeatedly evolved in many animal lineages and show a tremendous diversity of forms and functions. The cuticle of many insects is enriched with elements other than Calcium, a strategy of hardening that is taxonomically widespread but apparently poorly variable among clades. Here, we investigate the evolutionary potential of the enrichment with metals in insect cuticle at different biological levels. We combined experimental evidence of Zinc content variation in the mandibles of a target species (Chorthippus cazurroi [Bolívar]) with phylogenetic comparative analyses among grasshopper species. We found that mandibular Zinc content was repeatable among related individuals and was associated with an indicator of fitness, so there was potential for adaptive variation. Among species, Zinc enrichment evolved as a consequence of environmental and dietary influences on the physical function of the jaw (cutting and chewing), suggesting a role of natural selection in environmental fit. However, there were also important within and transgenerational environmental sources of similarity among individuals. These environmental influences, along with the tight relationship with biomechanics, may limit the potential for diversification of this hardening mechanism. This work provides novel insights into the diversification of biological structures and the link between evolutionary capacity and intra- and interspecific variation.Efforts to decrease nurse-reported workplace bullying (WPB) is an interest among researchers, nursing leaders, and healthcare organizations. Varying conceptual definitions and measurement approaches of WPB, however, have created barriers for researchers to provide reliable and consistent information regarding WPB. In this paper, the authors aim to (1) evaluate the reliability and construct validity of the Short Negative Acts Questionnaire (SNAQ) in a sample of U.S. PS-1145 nurses working in hospitals located throughout Alabama, (2) determine targets and non-targets of WPB, and (3) evaluate the criterion validity of the SNAQ based on WPB classification. The internal consistency reliability and construct validity of the SNAQ in 943 Alabama registered nurses was evaluated using Cronbach's α and confirmatory factor analysis. An exploratory factor analysis was conducted to explore the underlying structure of the SNAQ. Targets and non-targets of WPB were identified using latent class analysis of the SNAQ and by the self-labeling item. Agreement between the two methods was evaluated with Cohen's κ. Using both methods, the association between WPB classification and outcomes empirically associated with nurse-reported WPB was evaluated with random effects multiple logistic regression to determine criterion validity. The results indicate that the SNAQ is a reliable and valid instrument to explore WPB in a sample of U.S. registered nurses working in hospitals throughout Alabama.
