Abstract
Background: Diabetes is the most common metabolic diseases and its vascular complications are main cause of death in diabetic patients. Patients with hyperglycemia, dyslipidemia and oxidative stress are prone to diabetes complications. The goal of this study was investigation of the effect of cysteine (Cys) on hyperglycemia, lipid profile, atherogenic index, glyoxal, methylglyoxal, oxidative stress and, glycation and oxidation of LDL in the rat model of diabetes –atherosclerosis.
Methods: Diabetes was induced in the rats using Streptozotocin injection then they put on the atherogenic diet. The groups under study were including of control and diabetic rats, and two other similar groups under Cys (0.05 % in dirking water) treatment. After one month, fasting blood sugar (FBS), lipid profile, atherogenic index (LDL/HDL), glycated and oxidized LDL, AGEs, glyoxal, methylglyoxal, Advanced oxidation protein products (AOPP) as an oxidative stress index and weight of rat was measured.
Results: Diabetic-atherosclerotic rat groups significantly showed higher level of FBS, triglyceride, cholesterol, LDL, atherogenic index, glycated and oxidized LDL, glyoxal, methylglyoxal and AOPP than control group. These parameters significantly (P < 0.001) reduced in diabetic group treated with Cys in comparison of untreated.
Conclusion: Cysteine with improving property on glycemic and lipemic conditions, inhibitory activity on glycation and oxidation of LDL and reduction of oxidative stress in diabetic-atherosclerotic rats could recommended as a drug for prevention of diabetes complications.

Abstract
Background: The hepatokines are now considered potential targets for the treatment of type 2 diabetes disorders. The aim of this study was to investigate the effect of 12 weeks combined training with Canagliflozin on some hepatokines in type 2 diabetic men.
Methods: In this quasi-experimental study, 44 men with type 2 diabetes (Mean age 33.2 ± 4.5 years, body mass index 27.3±3.0) from Tehran city in 2019 were randomly divided into four groups (n=11) of control, drug, exercise and exercise-drug groups. Combined training was performed 3 sessions per week, 45 minutes for 12 weeks. Subjects were given 200 mg of canagliflozin for 12 weeks. Blood samples and anthropometric characteristics were obtained before and 24 hours after the intervention at 12-hour fasting. Data were analyzed using two-way ANOVA with repeated measures, t-test and Bonferroni post hoc test at P<0.05.
Results: The results showed that 12 weeks of exercise with Canagliflozin intervention significantly reduced angiopoietin-3 and angiopoietin-4, FGF-21 and HFREP-1 levels in type 2 diabetic men (P=0.001). Also, after the intervention of exercise with Canagliflozin, levels of angiopoietin-3, angiopoietin-4, FGF-21, and HFREP-1 were significantly lower than the pre-test (P<0.001).
Conclusion: According to the results of research, it is possible that intervention of exercise with Canagliflozin can help treat of disorders due to type 2 diabetes by reducing hepatokines.

Abstract
Background: Aging is associated with Sarcopenia as well as oxidative stress (OS) caused by Ferroptosis. The aim of the present study was to investigate the effect of aerobic exercise training (AT) on OS caused by ferroptosis in sarcopenia model mice.
Methods: Twenty-one C57BL/6 mice (16-24 wks. age) sarcopenia model with an average weight (25-35 g), and 21 healthy mice (6-7 weeks age) were randomly assigned to the following (1) healthy-young control (HYC; n= 7), (2) aerobic training-young (ATY; n= 7), (3) healthy-old control (HOC; n= 7), (4) old control-sarcopenia model (OCS; n= 7), (5) aerobic training-healthy-old (ATHO; n= 7), (6) healthy-old sarcopenia model (HOS= 7). The intervention group underwent AT for eight weeks, five sessions per week at an intensity of 60-80% of aerobic capacity (VO2max). The expression of the glutathione peroxidase (GPX-4) and superoxide dismutase (SOD) genes was measured using Real Time PCR. The Malondialdehyde (MDA) and Fe²⁺concentration in the gastrocnemius muscle was also measured.
Results: It was observed that the enzymes gene expression of SOD and GPX-4 in the (OSC) was significantly decreased compared to the (HOC) (P= 0.001, P= 0.002, respectively), and the MDA and Fe²⁺ was significantly increased (P= 0.001; P= 0.002, respectively). Also, the of SOD and GPX-4 gene expression of enzymes in the ATY, ATHO was significantly increased compared to the HYC, and HOS (P= 0.001; P= 0.002, respectively), and the concentration of MDA and Fe²⁺ was significantly decreased (P= 0.001; P= 0.002, respectively).
Conclusion: Finally, it can be said that aerobic training reduces oxidative stress caused by ferroptosis in Sarcopenia by increasing the enzymes GPX and SOD gene expression and reducing the concentration of MDA and Fe²⁺.
