Background and objectives: Cyber violence against women and girls is an emerging worldwide problem with a grave impact on individuals and societies. This study aimed to assess the problem of cyber violence against women among the Egyptian population. Methods: A convenience sampling method was used to recruit a total of 356 females. A self-completion questionnaire was distributed through one of the social media applications. Results: About 41.6% of the participants experienced cyber violence during the last year, and 45.3% of them reported multiple times of exposure. Social media was the most common way of exposure, and the offenders were unknown for 92.6% of the victims. The most commonly reported forms included 41.2% receiving images or symbols with sexual content, 26.4% receiving insulting e-mails or messages, 25.7% receiving offensive or humiliating posts or comments, 21.6% receiving indecent or violent images that demean women, and 20.3% receiving infected files through e-mails. The majority of the victims (76.9%) experienced psychological effects in the form of anger, worry, and fear; 13.6 % social effects; 4.1% exposed to physical harm; and 2.0% reported financial losses. Blocking the offender was the most common victims' response. Conclusion: Females in the Egyptian population are highly exposed to cyber violence, so implementation of anticyber violence program is essential to counteract this phenomenon.

The purpose of this paper is to investigate the relationship between green supply chain management (GSCM), sustainability and environmental uncertainties through corporate social responsibility (CSR) perspective. The study also tries to examine the mediating role of environmental uncertainties in the relationship between green supply chain management and sustainable performance. The study is carried out on firms in oil and gas sector of Kingdom of Oman and the results are analyzed using SEM-PLS. The findings reveal the fact that sustainable performance has become the primary objective of the organizations. Achieving sustainable performance is now becoming the main objective for business firms globally. Environmental obligation has caused many business firms to comply with the regulations. The green supply chain management is emerged as a significant determinant of CSR implantation success. According to this study the practice of the GSCM however requires integration among green supply chain partners to achieve sustainable performance. The findings have a number of managerial implications that could contribute to Omani's industries for planning and development a GSCI strategy through the internal, upstream, and downstream of the green supply chain perspective. The managers should develop a comprehensive environmental strategy, which requires the implementation of internal environmental management initiatives and cooperation from both suppliers and customers.

Nitric oxide (NO) plays various roles in insect immunity: as a cytotoxic component and as a signalling molecule; and immune-reactive lysozymes (IrLys) provide a first line of humoral immune functions against invading bacteria. Although there is considerable literature on eicosanoid and biogenic monoamine actions on insect immunity, there is no information on the role(s) of these chemicals in inducing NO and IrLys. We addressed this gap by challenging third instarSarcophaga(Liopygia)argyrostoma(Robineau-Desvoidy) with the Gram-positive bacteriumMicrococcus luteus. Here, we report that bacterial challenge induces elevation of NO and IrLys concentrations in haemocytes and in the fat body. The plasma pool content is comparatively low. Eicosanoid biosynthesis inhibitors (EBIs) lead to suppression of both NO and IrLys levels. Control larvae have low constitutive levels of NO and lysozyme concentrations. Octopamine (OA) elicits elevation of NO and IrLys concentrations. A similar effect is obtained by 5-hydroxytryptamine (5-HT) for NO. These data indicate immune-mediating roles of eicosanoids, OA and 5-HT in NO and IrLys activities.

Background: Regarding postmortem estimation, the evaluation of early histological and miRNA molecular changes have been of great concerns among forensic scientists due to uncertainty of known conventional methods. The histological and miRNA molecular changes in incisional wound remain poorly described. Purpose: This evaluation presents a histo-molecular approach that could be used to estimate the early post mortem interval in incisional wound. Methods: The histological and miRNA (205 and 21) changes were evaluated in 18 female albino rats with incisional wound at three interval times: 0, 24, and 48 h after infliction. Results: The wound margin showed progressive morphological changes with increasing postmortem interval. Inflammatory phase had appeared immediately after infliction. After this period, degenerative changes began. mRNA-205 and 21 expressions, detected via real-time PCR, were increased significantly to reach their higher levels at 24 h after wound infliction, then they were significantly diminished with increasing postmortem interval. Conclusions: Our results suggest that histological and miRNA-205 and miRNA-21 changes, occurred at perimortal incisional wound, could be helpful in forensic work regarding postmortem estimation.
