Background: increasing the population of aged, Consequently Increasing rate of chronic disease and to decreasing quality of life level caused many problems in different communities. The important aim of this study was surveying the effect of an educational intervention by use of the educational components of precede model on quality of life in the elders. Methods: This semi-empirical research was performed on 54 aged people in two group-case and control- for the Aged in 2009. In this study two questionnaires the designed questionnaire based on PRECEDE model and the questionnaire on the quality of life standard of the World Health Organization (WHOQOL) were used and the quality of life of the aged people in two groups before and after one month from the educational interference was evaluated. Independent t-test paired T-test, one way ANOVA, was used for data analysis. Results: The average total score of the quality of life of the aged people of test group, showed a meaningful difference before and after educational interference with a p quality less than 0.05, but there wasn’t a meaningful difference between total scores of two groups. Though the relationship of attitude (predisposing factors), enabling factors (skills) and behavioral factors with quality of life of a p quality less than 0.05 was meaningful. But knowledge (predisposing factor) and reinforcing factors didn’t show a meaningful relationship with the quality of life. Conclusion: It seems that the health, education and health promotion programs are effective on quality of life in the aged people.

Background: Exercise training is identified as a beneficial component of diabetes treatment plan. Angiogenesis process in diabetics can be affected by exercise activity. The purpose of this study is to determine the effect of aerobic exercise on the expression of mir-126 and capillary density in the cardiac tissue of diabetic rats.

Methods: Twenty diabetic male Wistar rats (mean weight, 191.9±10.85) were divided into two groups of control (n=10) and training (n=10) and the groups were matched based on weight. 48 hours after the last training session, cardiac tissue samples were taken after an overnight fast. Mir-126 expression was used through Real Time PCR. Also, immunohistochemistry (alkaline phosphatase activity) was used to measure the cardiac muscle capillary density.

Results: Independent t-test showed that the 8-week aerobic training significantly increased the expression of mir-126(p=0.001) and capillary density (p=0.018) of cardiac tissue in the exercise group compared to the control group.

Conclusion: The results of this study indicate that the development of angiogenesis by aerobic exercise in diabetic conditions; can be expressed as a non-drug treatments for aerobic exercise and can be used to improve heart perfusion.

Background: Cardiomyopathy is a side effect caused by diabetes. Prolonged hyperglycemia gives rise to an increase in the expression of the receiver gene RAGE subsequently triggering pathogenesis cardiac signaling pathways in the heart of rats with type II diabetes. The present paper aims to examine how a 12 week Resistance training on gene expressions RAGE, ICAM, VCAM in the heart of diabetic rats with STZ.
Methods: 16 male Wistar rats with weight mean ranging from 200 ± 20 g were randomly assigned to two groups of Resistance diabetes (n = 8) and control diabetes (n = 8) and were kept under lab circumstances. A 12 week Resistance training was administered with the experimental group and 48 hours after the end of the last training session the rats were made unconscious and examined. Their hearts were, afterwards, cut out and the extent of gene expressions RAGE, ICAM, VCAM in the left ventricular heart was measured using Real time-PCR method.
Results: The results indicated there was a significant difference between left ventricular heart of the Resistance diabetes and that of control diabetes in terms of gene expression RAGE, yet no significant difference was detected between the two groups in terms of gene expressions ICAM, VCAM.
Conclusion: According to the results, in seems that Resistance trainings effectively reduce gene expressions RAGE and reduction pattern but non-significant in the Gene ICAM, VCAM in left ventricular heart of diabetic rats and therefore can be considered an effective way in reducing pathogenesis cardiac signaling pathways in the heart of rats with type II diabetes.

Background: Physical activity plays a major role in the prevention of cardiovascular disease and diabetes, but the effect of intense activity on endoplasmic reticulum proteins and apoptosis and necroptosis in diabetic conditions is unclear. The aim of the present study was to investigate the changes of PERK and CHOP proteins in endoplasmic reticulum of cardiac myocytes of diabetic Wistar rats following continuous and interval exercise.
Methods: For this purpose, 32 male white wistar were purchased and were randomly divided into 4 groups of hemogenus 8 rats in each group: Healthy control (C), Diabetic control (D), Diabetic with moderate-intensity continuous training intensity at the 55min on 26 m/min speed (D+MICT) and Diabetic with high-intensity interval training intensity at the 85-90% of maximum speed (D+HIIT); 5 days/week for 8 weeks. For evaluate changes in the expression of the proteins associated with apoptosis and necroptotic death in the diabetic heart muscle myocardium, based on Western blot analysis will be used. Also, the one-way analysis of variance (ANOVA) is used to determine differences between the study groups.
Results: The results showed that induction of type 2 diabetes increased apoptotic and necroptosis cell death (P≥0.05). Therefore, both continuous and intermittent aerobic exercise modulate apoptotic cell death. And both intermittent and continuous exercise had a significant effect on cell necroptosis death.
Conclusion: It seems that different levels of aerobic exercise have different effects on cardiac myocytes cell death in diabetic rats. But more research is needed to confirm the death of diabetic necroptics.
