Occupational stress among male employees of esfahan steel company, Iran: Prevalence and associated factors

Background: Lack of data on occupational stress among Iranian industrial employees persuaded us to design and conduct this study to evaluate the prevalence and associated parameters of occupational stress among male employees of the Esfahan Steel Company (ESCO), one of the biggest industrial units in Iran. Methods: In this cross-sectional study, 400 male employees were sampled from the operational divisions of the company. Socio-demographic data and stress-related variables were entered into a logistic regression to determine significant associated factors of occupational stress among the participants. Results: From all samples, 53 were found as stressful. A monthly salary of less than 600 (OR = 1.88, 95 confidence interval CI = 1.21-2.94), family-related problems (OR = 2.75, 95% CI = 1.22-6.21), work environment (OR = 3.09, 95% CI = 1.78-5.33) and having a second job (OR = 2.68, 95% CI = 1.78-6.78) were significantly associated with the outcome. Conclusions: Attention to some variables, especially economic problems and the work environment of employees, might play a protective role against the prevalence of occupational stress, not only among the employees of ESCO but also among all industrial employees in Iran

High-levelexpression of functional recombinant human coagulation factor VII in insect cells

Abstract: Recombinant coagulation factor VII (FVII) is used as a potential therapeutic intervention in hemophilia patients who produce antibodies against the coagulation factors. Mammalian cell lines provide low levels of expression, however, the Spodoptera frugiperda Sf9 cell line and baculovirus expression system are powerful systems for high-level expression of recombinant proteins, but due to the lack of endogenous vitamin K-dependent carboxylase, expression of functional FVII using this system is impossible. In the present study, we report a simple but versatile method to overcome the defect for high-level expression of the functional recombinant coagulation FVII in Sf9 cells. This method involves simultaneous expression of both human γ-carboxylase (hGC) and human FVII genes in the host. It may be possible to express other vitamin K-dependent coagulation factors using this method in the future. Keywords: Baculovirus; γ-carboxylase; Coagulation FVII; Factor VII; Insect cel
