Green operations of organizations and enhancement of corporate social responsibility hinges upon leaders. This study investigated the influential role performed by environmentally specific servant leadership in provoking voluntary pro-environmental behavior of employees. The findings illuminate a serial chain mediation model that originates as a result of environmentally specific servant leadership and leads toward psychological empowerment, and organizational identity, ultimately leading toward voluntary pro-environmental behavior. Data from the textile sector of Pakistan uncovered that environmentally specific servant leadership prompted the voluntary pro-environmental behavior of employees. Moreover, environmentally specific servant leadership was significantly linked with voluntary pro-environmental behavior through psychological empowerment. The study supports the serial mediation of psychological empowerment and organizational identity in stirring voluntary pro-environmental behavior. An organizational psychological mechanism has been unraveled that can help organizations achieve a high level of sustainability and can serve as a catalyst for organizational green operations.
Mosquitoes are capable of carrying complex pathogens, and their feeding habits on the mammalian blood can easily mediate the spread of viruses. Surveillance of mosquito-based arbovirus enables the early prevention and control of mosquito-borne arboviral diseases. The climate and geography of Yunnan Province in China are ideal for mosquitoes. Yunnan shares borders with several other countries; therefore, there exists a high risk of international transmission of mosquito-mediated infectious diseases. Previous studies have focused more on the Sino-Laos and Sino-Myanmar borders. Therefore, we focused on the neighborhoods of Malipo and Funing counties in Wenshan Prefecture, Yunnan Province, China, which are located along the Sino-Vietnam border, to investigate the species of mosquitoes and mosquito-borne viruses in the residential areas of this region. This study collected 10,800 mosquitoes from 29 species of 8 genera and grouped to isolate mosquito-borne viruses. In total, 62 isolates were isolated and classified into 11 viral categories. We demonstrated a new distribution of mosquito-borne viruses among mosquitoes in border areas, including Tembusu and Getah viruses, which can cause animal outbreaks. In addition, Dak Nong and Sarawak viruses originating from Vietnam and Malaysia, respectively, were identified for the first time in China, highlighting the complexity of mosquito-borne viruses in the Sino-Vietnam border region. The awareness of the importance of viral surveillance and prevention measures in border areas should be further encouraged to prevent future outbreaks of potentially infectious diseases.
This study investigated the effect of different reheating treatments on gel properties and flavor changes of surimi products. As the reheating temperature increased from 90 °C to 121 °C, the heat-induced proteolysis produced more abundant umami and sweet amino acids, which took part in the conversion of IMP to AMP, thus enhancing the taste profiles. Reheating increased the exposure of active -NH2 terminals in proteins, which boosted Maillard and Strecker reactions with carbonyl compounds originated from fatty acid oxidation, thus not only reducing the aldehydes and esters contents but also lowering the whiteness of surimi products. Reheating at 90 °C prohibited the production of warmed-over flavor (WOF) and well-preserved the textural characteristics, but high temperatures ≥100 °C were prone to generate furan as the major WOF substance and to destroy gel structures. Collectively, this study provides new insights on understanding the role of reheating on sensory properties of surimi products.
This study examined bone morphogenetic protein 2 (BMP2) expression in oral squamous cell carcinoma (OSCC) and its effects on the biological behavior of OSCC cells, along with potential underlying mechanisms. BMP2 expression in OSCC was analyzed using mRNA data from The Cancer Genome Atlas and Genomics Expression Omnibus Database (GEO). SCC9 cells were transfected in vitro with small interfering RNA targeting BMP2 (si-BMP2), a negative control sequence (si-NC), BMP2 plasmid, or empty plasmid (vector). After transfection, Cell Counting Kit-8 assays, colony formation, scratch wound healing, Transwell, flow cytometry, quantitative reverse transcription polymerase chain reaction, and Western blot analyses were conducted to assess changes in SCC9 cell behavior in response to altered BMP2 expression and to explore relevant signaling pathways.BMP2 upregulation promoted SCC9 cell proliferation, migration, and invasion; inhibited apoptosis; and activated the Smad1/5 and p38 signaling pathways. Conversely, BMP2 downregulation inhibited SCC9 cell proliferation, migration, and invasion; promoted apoptosis; and suppressed the Smad1/5 and p38 pathways. BMP2 is highly expressed in OSCC and may drive its progression through the BMP/Smad and p38 mitogen-activated protein kinase signaling pathways, indicating potential prognostic value and promise as a therapeutic target for small-molecule OSCC treatments.
