Aim: Regular physical activity has several physical, psychological and social benefits. However, it is a global health problem, especially among ICU nurses. Therefore, in order to improve nurses’ physical activity, it is required to determine the effective correlated factors. The aim of this study was to delineate predictive factors on the physical activity of ICU nurses based on a trans-theoretical model (TTM) using path analysis.
Method: Accordingly, in this cross-sectional study, 82 nurses from eight intensive care units of six hospitals in Guilan University of Medical Sciences completed the translated version of Global Physical Activity Questionnaire (GPAQ) and another questionnaire, which included a range of constructs from the TTM. Data were analyzed using bivariate correlation and path analysis.
Findings: It was revealed that self-efficacy (β=0.24) and Pros (β=0.18) had a direct effect on the participants’ physical activities. It is important to state that self-efficacy was effective on the participants, behavioral physical activity both directly and indirectly. Totally, self-efficacy with the path coefficient of 0.62 was considered as the strongest predictive factor of physical activity among the ICU nurses.
Conclusion: To enclose, the determined effective factors in improving the ICU nurses’ physical activity were expected to be of more concern, especially self-efficacy as the strongest one.

Aim: Hypertension is a chronic and asymptomatic disease leading to death of at least 45% of patients with cardiovascular diseases (CVDs). Self-care is important to minimize the risks and complications caused by hypertension.
This aim of the present study was to determine the predictive power of constructs of the Health Belief Model (HBM) in self-care behaviors of patients with hypertension.
Methods: This was a descriptive-analytic study of cross-sectional type carried out on 125 patients over 30 years old with hypertension who referred to the rural health centers in Rasht city. Sampling was done in multi-stage form, and the patients were selected randomly. To collect data, a valid and reliable questionnaire containing demographic information and questions of constructs of the HBM and self-care behaviors was used.
Findings: Based on Pearson’s correlation analysis, a significant and negative relationship was observed between self-care behaviors and construct of perceived barriers. Also there was a significant and positive relationship between self-care behaviors and the construct of cues to action. Based on linear regression analysis, the HBM could predict 19% of variance of self-care behaviors by two constructs of perceived barriers (B=0.22, SE=0.04, P=0.01) and cues to action (B=0.19, SE=0.06, P=0.02).
Conclusion: According to the predictive power of the HBM and the role of constructs of perceived barriers and cues to action in self-care behaviors of patients with hypertension, it is needed to focus on educational interventions based on this model to reduce the perceived barriers and influencing the cues to action.

Biodiesel as a clean fuel is renewable, biocompatible and free of polycyclic aromatic hydrocarbons that could be deriving from animals, plants, fungal, algae and bacteria resources. Among these resources, oleaginous fungi due to the high capability to synthesize and accumulation of triacylglycerol are the best source for biodiesel producer. So, in order to providing approaches for increase biodiesel production based on biotechnology, molecular investigation in these organisms could be promising approach, which have been attentioned in this study. In this regard, a precise survey on the related molecular mechanisms led to reveal Malic enzymes as the effective and critical proteins in lipids production and accumulation in oleaginous fungi. Structural characterization of the genes, led to reveal that they are different in the length and GC content as well as they are continuous in the sequence context. Moreover, structural characterization of the enzymes led to determine their localization in the cells, present the functional domains with capability of post-translational modifications in all of them, which are including MAO1_MF, Malic_M and malic. Homologous sequences survey of the enzymes led to introducing fungal species with possible capability for lipid production.structural modeling of the selective malic and malic like enzymes led to provided suitable models in structure and quality in function with binding affinity to malate. In general, the results of this study, while introducing suitable fungal species for securance of biomass, led to reveal effective enzymes with special features that could be useful in tracing the capable strains or transgenesis modification.
