Abstract

Abstract Background & Objectives: The evidences from various studies showed that brain cortical activity is affected by the affective induction. On the other hand, the affective tendency are associated with extraversion and neuroticism. Hence, the purpose of this study was to examine the differences in activity of different areas of brain cortex in both basic and affect induction status with regard to personality dimensions and sex. Material & Methods: 33 right-handed volunteers psychology students (17 males, 16 females) were selected and matched based on their general health scores. They were divided into two groups with positive and negative induction. Some video clips were made by researcher to induce affect. Research's tools include video clips, EEG, Eysenck Personality Inventory (EPI), General Health questionnaire (GHQ-28), Positive and negative affect scales (PANAS), The Briggs-Nebes's hand preference questionnaire. After quantifying, data were analyzed by means of Independent-samples T and Pearson correlation tests. Results: The right temporal activity in extraverts was more than introverts under positive affect induction. Furthermore, under the induction of negative affect, activity rates in right temporal, left temporal, right posterior and left posterior areas were more than status of positive affect induction. Significant inverse relationship was found between extraversion and activity of posterior, frontal and temporal right's areas in basic status. The brain activities of anterior, temporal and posterior right’s areas in men at the basic status were more than those of women. Conclusion: The Individuals' brain activity induced by positive & negative affect induction was different. In addition, personality dimensions had effect on different sites and areas of cortical activity. Sex can also considered as another effective factor in activity of some of these sites.

Abstract

Introduction: Patients with type 2 diabetes with high insulin resistance are also at high risk for non-alcoholic fatty liver. The purpose of the present study was to investigate the effect of 8 weeks of HIIT and combined training on serum levels of liver enzymes and insulin resistance index in women with type 2 diabetes.
Methods: 54 women with type 2 diabetes (age 55.77 ± 5.92 years, BMI 28.98 ± 4.9 kg/m2 and HbA1c 9.41 ± 0.82%) were randomly and equally divided into HIIT, combined training and control groups, and they received interventions for 8 weeks (3 sessions per week). Blood samples were taken 24 hours before and 48 hours after the protocol and after 12 hours fasting state. Two-way ANOVA (time*group) tests for between-group comparisons and Paired-sample t tests for within-group comparisons were used.
Results: Significant differences were observed in HbA1c (P = 0.009), glucose (P = 0.007), insulin (P = 0.036), insulin resistance (P = 0.008) and AST (P = 0.005) between study groups. Tukey post-hoc test revealed that there was a significant difference between HIIT and combined training groups compared to control group in HbA1c (Respectively, P = 0.001 and P = 0.010), glucose (Respectively, P = 0.001 and P = 0.001), insulin (Respectively, P = 0.001 and P = 0.001), insulin resistance (Respectively, P = 0.001 and P = 0.001) and AST (Respectively, P = 0.006 and P = 0.006). There were no significant differences between HIIT and combined training groups (P > 0.05) in any of the markers.
Conclusions: Considering the significant changes in AST enzyme and insulin resistance, it seems that HIIT and combined training both have favorite effects on AST enzyme and insulin resistance. Therefore, both types of exercise are recommended for these patients
