Impact of Passive Leadership on Organizational Citizenship Behavior and Turnover Intentions; Mediating Effect of Organizational Interpersonal Trust

This study investigates the impact of passive leadership on organizational citizenship behavior and turnover intentions with the mediating effect of organizational interpersonal trust. Data has been collected from a sample of 180 working at managerial levels in public and private sector universities based in Islamabad. Findings of the current study confirms that passive leadership is negatively associated with organizational citizenship behavior and employee turnover intentions and the mediating role of organizational interpersonal trust confirms the partial mediation between these relationships. The study provided with new insights into the body of knowledge and also provided with practical implications. Limitations of the current study along with the future directions of research also discussed at the end

Priming with caffeic acid enhances the potential and survival ability of human adipose-derived stem cells to counteract hypoxia

The therapeutic effectiveness of stem cells after transplantation is hampered by the hypoxic milieu of chronic wounds. Prior research has established antioxidant priming as a thorough plan to improve stem cell performance. The purpose of this study was to ascertain how caffeic acid (CA) priming affected the ability of human adipose-derived stem cells (hASCs) to function under hypoxic stress. In order to study the cytoprotective properties of CA, hASCs were primed with CA in CoCl2 hypoxic conditions. Microscopy was used to assess cell morphology, while XTT, Trypan Blue, X-gal, LDH, Live Dead, scratch wound healing, and ROS assays were used to analyze viability, senescence, cell death, proliferation, and reactive oxygen species prevalence in the cells. According to our findings, CA priming enhances hASCs' ability to survive and regenerate in a hypoxic microenvironment more effectively than untreated hASCs. Our in-vitro research suggested that pre-treatment with CA of hASCs could be a unique way to enhance their therapeutic efficacy and ability to survive in hypoxic microenvironments
