Abstract
Background and objectives: Fibroblast growth factor 21 (FGF21) and fetuin A are thought to be involved in the pathogenesis of metabolic disorders, such as type 2 diabetes. On the other hand, regular physical activity has an important role in the prevention and management of type 2 diabetes. The purpose of this study was to investigate effect of moderate aerobic exercise on serum levels of FGF21 and fetuin A in women with type 2 diabetes.
Methods: This was a semi-experimental study with a pretest-posttest design. The study was performed on 28 women with type 2 diabetes aged 40-50 years (mean weight: 70.58 ± 2.11) who were randomly divided into an exercise group (n=14) and a control group (n=14). The training intervention consisted of eight weeks of moderate aerobic exercise at 60-70% of maximum heart rate, five times a week. Serum levels of FGF21, fetuin A and some metabolic parameters were evaluated before the first session and 48 hours after the last session. All statistical analyses were performed in SPSS (version 24) using repeated measures ANOVA and at significance of 0.05.
Results: The eight-week aerobic training intervention caused a significant increase in FGF21 and insulin sensitivity as well as a significant decrease in fetuin A, fasting blood sugar and HbA1c (P=0.001).
Conclusion: As a complementary therapy, regular aerobic exercise can be beneficial for type 2 diabetes patients in improving some metabolic parameters as well as FGF21 and fetuin A levels.

Abstract
Background and objectives: It has been suggested that irisin and fibronectin type III domain-containing protein 5 (FNDC5) can increase energy expenditure, promote weight loss and improve insulin resistance in diabetic patients by affecting white and brown adipose tissues. In this study, we investigate effect of adipose tissue-derived stem cell transplantation and six weeks of aerobic exercise on FNDC5 and irisin levels in streptozotocin-induced diabetic rats.
Methods: Forty-eight rats (weighing 220-240 g and aged nine weeks) were divided into six groups of control, sham, diabetes control, diabetes + exercise, diabetes + stem cell and diabetes+ exercise + stem cell. The exercise group ran on running wheel at intensity of 60-70% VO2max, five days a week for six weeks. Next, 1.56 × 106 stem cells extracted from human adipose tissue were injected into the tail vein of streptozotocin-induced diabetic rats. Finally, FNDC5 and irisin plasma levels of the mice were measured using enzyme-linked immunosorbent assay kits.
Results: FNDC5 and irisin levels reduced significantly in the diabetes control group (P=0.0001). FNDC5 levels in the diabetes + exercise + stem cell and the exercise group increased significantly compared to the diabetes control group (P=0.0001). The irisin level in the diabetes + stem cell + exercise group, exercise group and stem cell group increased significantly compared to the diabetes control group (P=0.0001).
Conclusion: The results indicate that aerobic exercise program and stem cell therapy alone and combined can significantly increase plasma irisin levels. Given the favorable effects of adipose tissue-derived stem cell injection and aerobic exercise on FNDC5 and irisin levels, this strategy could be further evaluated in coping with the adverse effects of diabetes on metabolism and aging

Abstract
Background and objectives: Cardiac apoptosis is one of the most important cardiovascular complications of diabetes. We aimed to investigate the changes of Bax, Bcl2 and caspase 3 in cardiac tissue of diabetic rats after six weeks aerobic exercise.
Methods: Thirty two male Wistar rats were randomly divided into healthy control, diabetes control and diabetes + exercise groups. Diabetes was induced by intraperitoneal injection of streptozotocin solution (55 mg/kg). Two weeks after the injection, fasting blood glucose levels were measured to confirm induction of diabetes. The exercise program was performed five days a week for six weeks. Variables were evaluated by ELISA and western blot analysis. All statistical analyses were performed in SPSS (version 22) using ANOVA and at significance of 0.05.
Results: The induction of diabetes in the control groups resulted in a significant increase in Bax, Bax/Bcl2 ratio and a significant decrease in Bcl2 levels (P=0.024). The six-week training exercise in diabetic groups significantly decreased Bax and Bax/Bcl2 ratio and significantly increased Bcl2 (P=0.018).
Conclusion: Our finding showed that diabetes could increase apoptosis in cardiac tissue. In addition, the six-week aerobic exercise can be used as a non-pharmacological strategy to reduce diabetes-related apoptosis in cardiomyocytes.

Abstract
Background and objectives: Diagnosis glucose intolerance in pregnancy is very important in preventing maternal and fetal complications. In this study, we compared hematological and biochemical characteristics of healthy pregnant women and women with gestational diabetes mellitus (GDM) to find predisposing and prognostic variables of GDM.
Methods: In this study, 80 pregnant women (at 24-28 weeks of pregnancy) were divided into a GDM group and non-GDM group by performing oral glucose tolerance test using 75 g glucose according to the International Association of the Diabetes and Pregnancy Study Groups criteria.
Results: The mean age of women with GDM was significantly higher than those without GDM (p=0.048). Other variables including body mass index, gestational age and daily sleep duration did not differ significantly between the two groups (P>0.05). There was a significant association between family history of diabetes and incidence of GDM (p=0.040). In addition, the C-peptide level was significantly higher in pregnant women with GDM (p=0.004).
Conclusion: Considering the role of C-peptide in predicting metabolic syndrome, it is suggested to use this factor for identification of GDM patients.

Abstract
Background and objectives: Programmed autophagy is a genetically and evolutionarily conserved process that destroys long-lived cellular proteins and organelles. This study aimed to investigate effects of continuous and interval exercise training with or without atorvastatin supplementation on Beclin1, LC3-I and LC3-П expression in old rats with type 2 diabetes.
Methods: Sixty three male Wistar rats were divided into eight groups. Continuous exercise was performed at a speed of 15-29 m/min for 5-22 minutes. Interval exercise program consisted of six 2.5-minute sets that included a four-minute rest period between each set. The rats in the supplementation groups also received 20 mg/kg body weight atorvastatin daily via intraperitoneal injection. At the end of the training period, the expression of Beclin1, LC3-I and LC3-П in soleus muscle was measured by RT-PCR. One-way ANOVA was used for data analysis at statistical significance of 0.05.
Results: The results showed that both exercise trainings with or without atorvastatin significantly reduced LC3I, LC3-II and Beclin1 compared with the diabetic control group (P<0.05). In addition, the effects of the trainings and atorvastatin supplement did not differ significantly (P>0.05).
Conclusion: The results indicate that continuous and interval exercise program alone and combined with atorvastatin supplementation could significantly reduce LC3-1, LC3-II and Beclin1 level in soleus muscle of old diabetic rats.

Abstract
Background and objectives: Clinical evidence has demonstrated the important role of adiponectin in insulin signaling pathways in target tissue. The aim of this study was to determine effects of aerobic training on insulin sensitivity, glucose level, and adiponectin expression in subcutaneous adipose tissue of type 2 diabetic rats.
Methods: Type 2 diabetes was induced in 14 male wistar rats by intraperitoneal injection of nicotine amide and streptozotocin. The rats were randomly divided into an exercise group (n=7) and a control group (n=7). The rats in the exercise group performed aerobic training in from of treadmill running, five sessions a week, for 12 weeks. Subjects in the control group did not perform any training. Glucose level, insulin level, insulin sensitivity, and adiponectin expression in subcutaneous adipose tissue were determined at baseline and 48 hours after the lasting training session. Independent t-test was used for comparing the variables between the study groups.
Results: Aerobic training resulted in a significant increase in serum insulin (p=0.006), insulin sensitivity (p=0.003), and adiponectin expression in subcutaneous adipose tissue (p=0.037) compared with the control group. In addition, the training caused a significant decrease in fasting glucose level compared with the control group (p<0.001).
Conclusion: Based on these findings, the decrease in blood glucose may be attributed to the improvement of adiponectin-dependent insulin signaling pathways in adipose tissue in response to aerobic training. However, more cellular-molecular studies are needed to understand the mechanisms responsible for these changes.

Abstract
Background and objectives: Increased oxidative stress and altered antioxidant levels play an essential role in the pathogenesis of diabetes mellitus. Menopause is associated with increased food intake, weight gain, metabolic disorders, and increased level of inflammatory and oxidative stress factors. This study evaluated effects of oleuropein extract on brain tissue and serum oxidative status in ovariectomized diabetic rats.
Methods: In this study, 40 female Wistar rats weighing 250±20 grams were randomly divided into four groups: control, sham (surgery without ovariectomy), ovariectomy+diabetes, and ovariectomy+diabetes+oleuropein supplementation. Diabetes was induced by intraperitoneal injection of streptozotocin. The rats in the treatment group received 60 mg/kg of oleuropein for 30 days by oral gavage. Finally, blood glucose, superoxide dismutase, glutathione peroxidase, total antioxidant capacity, and malonaldehyde levels were evaluated in serum and brain tissue samples.
Results: Weight, blood glucose level, and antioxidant enzymes activity increased significantly in the ovariectomy+diabetes group compared to the control group.
Conclusion: This study suggested that the administration of oleuropein extract has beneficial effects on blood glucose level and antioxidant status in serum and brain tissue of ovariectomized diabetic rats.

Abstract
Background and objectives: Diabetes mellitus is the most common metabolic disorder in the world. Here, we evaluated effects of resveratrol supplementation alone and combined with exercise on blood glucose, insulin, lipid profile, apoptosis biomarkers, and expression of farnesoid X receptor (Fxr), liver X receptor (Lxr), and sirtuin 1 (Sirt 1) genes in the liver of type 1 diabetic rats.
Methods: Streptozotocin was used to induce type 1 diabetes in Wistar rats. The rats were randomly assigned into seven groups. After treatment with resveratrol alone or combined with exercise training, the animals were sacrificed and lipid profile and levels of blood glucose and insulin were measured. Hepatocyte apoptosis was assessed by measuring the level of Bax and Bcl2 proteins using enzyme-linked immunosorbent assay kits. Expression of Fxr, Lxr, and Sirt1 was evaluated using real-time polymerase chain reaction. Comparison of the mean levels of all variables between different groups was performed using one-way analysis of variance, at statistical significance level of 0.05.
Results: Resveratrol significantly reduced the level of blood glucose and insulin compared with the control groups (p<0.001). It also significantly affected the lipid profile (p<0.001). Diabetes was significantly associated with decreased expression of Sirt1, Lxr, and Fxr and increased hepatocyte apoptosis. Resveratrol significantly improved the expression of all three genes (p<0.01). Overall, resveratrol supplementation combined with exercise was more effective than other methods.
Conclusion: The results indicate that that combination of resveratrol therapy with exercise could be beneficial for diabetic patients. However, more studies are needed to confirm this finding.

Abstract
Background and objectives: Considering racial/ethnic differences is necessary when recommending lifestyle modifications for patients with diabetes. Racial/ethnic diversity may affect hypoadiponectinemia responses to exercise training among individuals with type 2 diabetes. This systematic review and meta-analysis is the first to investigate effects of exercise training on circulating adiponectin concentrations in Iranians with type 2 diabetes.
Methods: Literature searches of the Cochrane Central Register of Controlled Trials were carried out using the following search strategy: [exercise OR training OR physical activity OR Training] AND diabetes AND adiponectin. Next, RCTs were included and compared with each type of supervised exercise (aerobic training, resistance training, or combined training). Pooled intervention effects were evaluated and reported as standardized mean difference (MD) and 95% confidence intervals using a random effects model. Subgroup and sensitivity analysis was performed for study heterogeneity and following primary screening full text of the articles was evaluated.
Results: Fourteen studies with 444 individuals (236 men and 128 women) were included in the analysis. The age of the participants ranged between 18 and 60 years. The number of exercise sessions per week ranged between 3 and 5. The duration of interventions ranged between 6 and 12 weeks. The meta-analysis showed that adiponectin levels increased significantly in diabetic subjects after physical activity (MD: 0.72 ng/dl, p<0.001,), but the heterogeneity of the study remained significant (I2= 89%).
Conclusion: Overall, physical exercise, particularly aerobic exercise, increases adiponectin levels in Iranians with diabetes. However, this effect of exercise may be influenced by race/ethnic differences, type of training, frequency, type of adiponectin measurement, and complex and heterogeneous exercise responses of individual with diabetes.

Abstract
Background: Omentin-1 plays an important role in insulin function. Despite numerous studies, the effect of interval training on this adipokine is still vague. This study aimed to elucidate the effect of high-intensity interval training (HIIT) on serum glucose, insulin, insulin resistance (IR), omentin-1 serum levels, and gene expression in the visceral adipose tissue in type 2 diabetic (T2D) rats.
Methods: In an experimental study, 20 male rats (8-10 weeks, weight: 250-270 g) were randomly divided into 2 groups: diabetic control (N=10) and diabetic training (N=10). The training protocol was 30 minutes of HIIT (1-min run, 2-min rest) performed 5 days a week for 4 weeks. Fasting blood glucose, insulin resistance, omentin-1 serum level, and gene expression were measured in the visceral fat 48 hours after the last exercise for both groups.
Results: The HIIT resulted in lower serum glucose and insulin resistance (P = 0.001), higher serum omentin-1 levels (P = 0.001), and higher visceral fat gene expression (P = 0.004) in the training group compared to the control group.
Conclusion: Lower serum glucose and insulin resistance and higher omentin-1 serum levels and gene expression in the training group can prove the effectiveness of HIIT training in T2D, although further research is required.

Abstract
Background: A higher occurrence of raised homocysteine levels has been reported in individuals with type 2 diabetes (T2D), particularly those with macroangiopathy and nephropathy. Given that hyperhomocysteinemia is a risk factor for T2D, mitigating this condition could potentially benefit T2D patients. This study aimed to investigate the influence of homocysteine on T2D and cardiovascular disease (CVD), as well as the factors that modify homocysteine levels.
Methods: This cross sectional, observational study was conducted on 122 individuals in a tertiary care center in Western India. Data related to anthropometry, demography, and biochemistry were gathered following established standards. Statistical analysis was performed using Chi-square test. A P-value of <0.05 was considered statistically significant.
Results: The findings indicated a significantly larger percentage of hyperhomocysteinemia in males, smokers, and individuals with elevated fasting blood sugar and HbA1c levels. The proportion of subjects with high homocysteine levels was notably greater in those with high total cholesterol and triglyceride levels. A significant correlation was observed between increased serum homocysteine levels and decreased serum folic acid and vitamin B12 levels in patients with ischemic heart disease.
Conclusion: Elevated homocysteine levels are observed in smokers and diabetic patients, potentially leading to CVD. Furthermore, this study found a correlation between an increase in serum homocysteine levels and a decrease in serum folic acid and vitamin B12 levels in patients with ischemic heart disease.

Abstract
Background: Type 2 DM is a heterogeneous group of disorders characterized by insulin resistance, impaired insulin secretion, increased glucose production, and abnormal fat metabolism. Diabetes mortality primarily results from microvascular complications such as diabetic retinopathy, nephropathy, and neuropathy, as well as macrovascular complications like coronary artery, peripheral vascular, and cerebrovascular diseases. Patients with diabetes usually have changes in adipose tissue metabolism and abnormalities in the secretion of adipokines such as leptin. The present study aims to study the relationship between serum leptin levels and lipid profile parameters among non-obese type 2 diabetes mellitus patients and non-diabetic individuals.
Methods: This hospital-based cross-sectional study was conducted among 41 type 2 diabetic patients and 41 non-diabetic individuals of both sexes between the ages of 40 and 70. Fasting blood glucose (FBS), serum leptin, total cholesterol (TC), triglyceride (TG), and high-density lipoprotein (HDL) levels were assayed.
Results: The mean serum leptin levels among diabetic patients were lower than those of non-diabetic individuals, and this difference in mean was statistically significant. The study showed a significant negative correlation between serum leptin, TC, TG, and low-density lipoprotein (LDL), and a positive correlation with HDL. In the final regression model, serum leptin showed a statistically significant association with FBS and HDL.
Conclusion: This study demonstrated that serum leptin levels can be a strong predictor of low HDL levels in diabetic patients. It can also contribute to raised levels of total cholesterol, triglyceride, and LDL, which are responsible for macrovascular complications in diabetics.

Abstract
Background: Although the anti-diabetic effects of various Ficus species have been investigated in animal models, research on the blood glucose-lowering potentials of Ficus lacor Buch Ham bark remains sparse. This study evaluated the blood glucose-lowering potentials of an aqueous extract derived from Ficus labor bark in a diabetic rabbit model.
Methods: Diabetes was induced in rabbits through intravenous administration of alloxan monohydrate (120 mg/kg). 36 rabbits were divided into six groups, each consisting of six animals. Control groups included a non-diabetic control (Distilled water) and a diabetic control (Distilled water). Two experimental groups received Ficus lacor extract at doses of 100 mg/kg (Low-dose) and 200 mg/kg (High-dose) orally for six weeks. Metformin was used as an active control. A non-diabetic group (Extract control) was also administered Ficus lacor extract at 200 mg/kg. Fasting blood sugar (FBS) and post-prandial blood sugar (PP2BS) levels were measured weekly over the 6 weeks. The percentage reduction in blood glucose levels was calculated and compared for each group.
Results: The administration of both low-dose and high-dose Ficus lacor extracts resulted in significant reductions in FBS and PP2BS levels in diabetic rabbits. After six weeks, the low-dose extract group exhibited an average reduction of 38.3% in FBS and 40.5% in PP2BS, whereas the high-dose extract group showed average reductions of 35.3% in FBS and 36.3% in PP2BS.
Conclusion: The aqueous extract of Ficus lacor bark demonstrates substantial glucose-lowering activity, indicating its potential utility as a therapeutic agent in diabetes management.

Abstract
Background: Diabetes Mellitus (DM) is a metabolic disorder whose pathophysiology has been linked to various genetic and environmental factors. The main mechanism of the development of complications has been implicated as inflammation-mediated. Various blood cell parameters are being used as early indicators of inflammation-mediated endothelial dysfunction; thereby predicting the severity or prognosis of DM. In this study, we aimed to evaluate the role of platelet-to-lymphocyte ratio (PLR) in predicting glycemic control in patients with DM.
Methods: This is a retrospective, hospital-based study conducted from August 2023 to December 2023. A total of 134 patients were included in the study. The hematological and biochemical reports of the study population were retrieved, and the data obtained was analyzed using SPSS software version 16.0.
Results: In this study, it has been found that PLR is significantly increased in patients suffering from DM with poor glycemic control compared to those patients with good glycemic control (P<0.001). In concordance with other studies, a positive association was observed between PLR and disease severity.
Conclusion: Based on the findings of the study, PLR may be used as a predictive marker in assessing the severity and prognosis of DM; however, the exact cut-off value is yet to be determined.

Abstract
Background: Various analytes are used to assess glycemic control in laboratory medicine. Glucose measurements show current glucose levels, but sample stability can be influenced by diet and stress. Hemoglobin A1c (HbA1c) is the best marker for long-term control but can be affected by elevated urea levels. This study compared glycated albumin (GA) and HbA1c in diabetic patients undergoing hemodialysis.
Methods: A comparative cross-sectional study was conducted with a sample size of 280 volunteers. Among these, there were 115 diabetic patients with end-stage renal disease (ESRD), 95 diabetic patients without ESRD, and 75 non-diabetic patients with ESRD. Laboratory measurements included HbA1c, GA, urea, and creatinine, assessed using standard laboratory techniques. Data analysis was carried out using SPSS statistical software.
Results: Levels of HbA1c were lower in diabetic patients with ESRD compared to diabetic patients without ESRD. In contrast, GA levels were higher in diabetics with ESRD. A significant negative association was observed between HbA1c levels and urea levels. However, creatinine levels were not associated with either HbA1c or GA.
Conclusion: The estimation of glycated hemoglobin levels can be affected by high blood urea. Therefore, GA may be a better glycemic indicator for diabetic patients with ESRD.

Abstract
Background: Diabetes mellitus (DM) is a metabolic disease characterized by hyperglycemia, disturbed lipid metabolism, and cardiovascular disease (CVD). Poor glycemic control results in lipid and lipoprotein abnormalities, suggesting that dyslipidemia is secondary to insulin resistance or factors closely related to insulin resistance. Glaciated hemoglobin (HbA1c) is a routinely used marker for long-term glycemic control. This form of hemoglobin is chemically processed through post-translational glycosylation that reflects the plasma glucose concentration during the last two to three months.
Methods: This cross-sectional study was conducted on blood samples from 592 cases referred to Dezyani Specialty Clinic, affiliated with the Golestan University of Medical Sciences. In patients with diabetes mellitus (DM) and non-diabetic individuals, hemoglobin A1c (HbA1c), total cholesterol (T-chol), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C) were measured.
Results: In the study, there were 460 female participants (76.9%) and 132 male participants (23.1%). Among them, 403 (67.4%) were diabetic patients, and 193 (32.4%) were non-diabetic. HbA1c levels were significantly lower in younger individuals than in middle-aged participants (p=0.000). No significant difference was found between middle-aged and older individuals (p>0.121). LDL levels were significantly lower in the young group than in the middle-aged group (p<0.001). Total cholesterol (TC) was also significantly lower in the young group compared to middle-aged and older groups (p<0.001).
Conclusion: HbA1c can be a helpful lipid and glycemic control marker in diabetes.

Abstract
Background: Type 2 diabetes mellitus (T2DM) is a non-communicable disease, manifesting hyperinsulinemia, insulin resistance, hyperglycemia, and low-grade chronic inflammation associated with various micro and macrovascular complications. The present study aimed to estimate vitamin D (Vit D) levels, total antioxidant capacity, and malondialdehyde (MDA) levels in T2DM patients compared with healthy individuals. In addition, we assessed Vit D, total antioxidant capacity, and MDA levels in patients with T2DM and their association with HbA1c, insulin resistance and lipid profile parameters.
Methods: Seventy patients with T2DM aged 35 to 50 years were selected and 70 healthy age-matched subjects were selected as controls. Serum Vit D and insulin were estimated by the enzyme-linked immunosorbent assay (ELISA). Glycosylated hemoglobin (HbA1C) was assessed by high-performance liquid chromatography (HPLC) method and other routine lipid profile investigations were carried out using a Beckman Coulter fully automated analyzer.
Results: Vitamin D levels significantly decreased in T2DM patients. HbA1C and insulin resistance values are significantly increased in type 2 diabetic patients. Vitamin D levels negatively correlated with MDA, insulin resistance, and HbA1c, while positively correlated with total antioxidant capacity. Nevertheless, there is no significant correlation between lipid profile parameters.
Conclusion: Vitamin D deficiency may be one of the vital risk factors responsible for increased oxidative stress in patients with T2DM. Regular monitoring and supplementation of Vit D are beneficial for the reduction of oxidative stress and vascular complications in these patients.

Abstract
Background: Leptin and adiponectin, two members of the adipokine family, play roles in increasing lipid metabolism and inhibiting lipogenesis. Reduced levels of these cytokines are associated with obesity and insulin resistance. This study aimed to determine the serum levels of leptin and adiponectin in type-2 diabetic patients with and without metabolic syndrome compared to a control group.
Methods: Three groups of individuals participated in this study: 47 type-2 diabetic patients with metabolic syndrome (DM+MetS), 25 type-2 diabetic patients without metabolic syndrome (DM-MetS), and 40 individuals with no history of diabetes or metabolic syndrome (Control group). Fasting blood samples were collected, and serum levels of fasting blood sugar, cholesterol, triglycerides, HDL-cholesterol, and LDL-cholesterol were measured using the enzymatic method. Blood pressure, height, and weight were recorded using stadiometers, while leptin and adiponectin levels were determined via enzyme-linked immunosorbent assay.
Results: A significant difference was observed between the DM+MetS group and the DM-MetS group in serum leptin (p = 0.004) and adiponectin (p < 0.001) levels. In patients with type-2 diabetes and metabolic syndrome, serum leptin (p = 0.530) and adiponectin (p < 0.001) levels were lower compared to the control group.
Conclusion: A decrease in the serum levels of key adipokines, such as leptin and adiponectin, in type-2 diabetic patients may serve as a predictor of metabolic syndrome.

Abstract
The aim of this study is to investigate the effect of 6 weeks of intermittent exercise on the serum level of nitric oxide, insulin resistance and some lipid profiles in male diabetic rats. Materials and methods: In this experimental study, 60 anesthetized rats (200±20) were randomly divided into 6 groups of 10:1-control-healthy, 2-sham, 3-periodic, 4-periodic+saline, 5-diabetic and 6- Diabetes + interval training were divided. Diabetes was induced by intraperitoneal injection of nicotinamide-streptozotocin. The subjects trained on the treadmill for 6 weeks, 5 sessions a week. 48 hours after the last training session, slaughter was performed and then glucose, insulin, nitric oxide, LDL, HDL, TG and cholesterol levels were measured. One-way variance test and Tukey's post hoc test were used for data analysis(p<0.05). Results: Induction of diabetes increased glucose and insulin resistance and decreased insulin and nitric oxide in the diabetic group compared to the control group. After 6 weeks of intermittent training in the diabetes group + intermittent training, the amount of glucose and insulin resistance decreased compared to the diabetes group, but the nitric oxide level increased compared to the diabetes group. But it had no effect on insulin levels. Also, 6 weeks of intermittent training had no significant effect on the amount of lipid factors in different groups(p<0.05). Conclusion: According to the results of the present study, it seems that interval training can create a protective effect against vascular diseases in diabetic patients by reducing insulin resistance and increasing nitric oxide, and as a result, improving vascular function.

Abstract
Introduction: DNA Glycation damages DNA by inducing breaks of strands, mutations, and finally changes in gene expression, which is assumed as a main factor in pathogenesis of diabetes and its complications. Therefore, antiglycation agents have been focused recently for preventing and alleviating diabetes complications. According to the reported antidiabetic effects of Tamarix aphylla (T. aphylla) leaves extract, this study was aimed to determine the effect of T. aphylla on glucose-mediated DNA glycation for the first time.
Methods: DNA incubated with glucose for 4 weeks and the inhibitory or fascilitatory effects of T. aphylla on DNA structural changes were studied by various techniques. These techniques were included UV–Vis, fluorescence spectroscopy, circular dichroism (CD) and agarose gel electrophoresis.
Results: The findings of UV–Vis and fluorescence spectroscopy showed that T. aphylla decreased the DNA-AGE (advanced glycation end products) formation. Based on the CD and agarose gel electrophoresis results, the structural changes of glycated DNA was decreased in the presence of T. aphylla.
Conclusion: Thus T. aphylla has beneficial effects against DNA glycation and could be a promising agent for ameliorate the adverse effects of glycation in the presence of glucose and conditions of raised blood glucose after confirming in further studies.
