Abstract
Background: Fetoin-A and -B are hepatokines that are related to type 2 diabetes. The aim of the present study was to investigate the effect of a period of resistance and endurance training with Ursolic acid consumption on the levels of Fetoin-A and -B in the liver tissue of elderly diabetics.
Methods: Fifty six 21-month-old male diabetic rats were randomly divided into seven equal groups of control (C), Ursolic acid supplement (UA), supplement+resistance exercise (UA+R), supplement+endurance exercise (UA+E), Resistance training (R), endurance training (E) and sham group (D). Resistance training protocol with intensity of 60% MVCC, 14-20 times of ladder climbing with one minute rest between each effort and endurance training including running on Treadmill at high intensity 60-75% and low intensity 30-40% of maximum speed for five days per week for eight weeks. Supplemented groups received 500 mg/kg UA in combination with a high-fat meal.
Results: Fetoin-A level was significantly decreased in UA, E, UA+E groups (p≤0.05) and only in R and UA+R groups, there was no significant decrease. Also, The amount of Fetoin-B in diabetic rats in the UA, E, R, UA+E groups decreased significantly (p≤0.05) and only in the UA+R training group there were no significant changes. The amount of Fetoin-A and Fetoin-B was significantly different between E and R and UA+R and UA+E groups (p≤0.05), which the largest decrease was in the UA+E group.
Conclusion: Considering the beneficial effects of exercise training as well as UA supplementation on hepatokines, it seems that the simultaneous application of two interventions of exercise training and UA supplementation has a more therapeutic effect on the hepatic hepatokines of diabetics.

Abstract
Background: Inflammatory protein C3 and IL-1β are significantly involved in the pathophysiology of type 2 diabetes (T2D) and Alzheimer's disease. Moreover, examining the importance of aerobic exercise timing (light vs. dark phase) can provide a better understanding of how exercise timing affects inflammatory markers associated with neurological diseases in older adult women with T2D. Therefore, this study aimed to investigate the effect of aerobic exercise timing on C3 and IL-1β levels in older adults’ women with T2D.
Methods: In this semi-experimental study, 45 women with T2D with an average age of 60 ± 5.07 years were divided into training groups (light and dark phase) and control (15 people in each group). Aerobic exercise was performed for 12 weeks at a moderate intensity (60-70% of heart rate reserve). Protein levels (C3 and IL-1β) were measured before and after the intervention using the ELISA method. Data were analyzed using SPSS27 software and ANOVA with a significance level of 0.05.
Results: Complement C3 was significantly lower in the dark phase exercise group compared to the control group (P= 0.0083). Additionally, the results showed that dark phase aerobic exercise significantly decreased C3 (P= 0.0028) and IL-1β (P= 0.0045) levels compared to baseline.
Conclusion: Aerobic exercise performed during the dark phase effectively reduced inflammatory protein levels of C3 and IL-1β in older adult women with T2D, suggesting it could be considered as a crucial strategy in managing this disease.
