Abstract
Depression is one of the most prevalent mental disorders in diabetics, which affects treatment course and disease prognosis. This study focuses on the association between diabetes and depression as well as depression and glycemic control.
Methods: 375 diabetic patients (type I and II) of diabetes clinic of Doctor Shariati Hospital and diabetes association of Iran participated in this cross-sectional study.Patients were screened for depression with Beck Depression Inventory. Then depressed subjects were
evaluated with DSM IV criteria for determination of the depressive disorders category.
Results: Depression was diagnosed with Beck Depression Inventory in 41.9% of patients. Of these patients major depressive disorder was defined in 23.7%, dysthymic disorder in 9.3% and association of two disorders in 0.8% of patients. Major depressive disorder was more prevalent in 31-59 year old group and dysthymic disorder in more than 60 year age group. Also depression was more prevalent in
women, diabetics with uncontrolled blood glucose and patients with diabetes complications.
Conclusion: Depression is a prevalent psychiatric disorder in diabetics, which is associated with female gender, poor glycemic control and diabetes complications. Therefore, glycemic control and prevention and treatment of diabetes complications can prevent depressive disorders in diabetics.

Abstract
Background: Constipation is the most common gastrointestinal complication in diabetic patients. Erythromycin mimics the effects of the gastrointestinal hormone Motilin in gastric contractile activity and insulin secretion. In this study, we compared the effects of Erythromycin and Metoclopramide on glycemic control and constipation in type 2 diabetic patients.
Methods: As a clinical trial, thirty-nine type 2 diabetic patients with constipation were divided into two groups. Patients in group 1 (n=24) were treated with erythromycin (400 mg/day before sleep) and participants in the second group (n=15) received metoclopramide (10mg 3 times / day before each meal) for 3 months. FBS, 2hPP BS, HbA1c and the frequency of defecations during a week were measured and compared before and after the intervention.
Results: In Erythromycin treated group, 2hPP BS decreased from 199.7 ± 47.0 before treatment to 174.0±46.3 after intervention (P=0.01) and a significant improvement in constipational symptoms was observed in both groups.
Conclusion: It seems that Erythromycin not only can improve symptoms of constipation but may have a role in glycemic control in type 2 diabetic patients.

Abstract
Background : Women with polycystic overy syndrome (PCOS) are sussceptible for developing type 2 diabetes (T2DM) and cardiovascular diseases. In view increased prevalence of T2DM in patients with PCOS and priority of prescription agents capable to decrease insulin resistances for them, It is important to diagnose PCOS in T2DM patients. The aim of this study was to evaluate the prevalence of PCOS in T2DM women.
Methods : Using ‘1990 National Institute of Child Health and Human Development Conference of PCOS’ criteria, 157 premenopausal women with T2DM were assigned into PCOS and non – PCOS groups after they were examined for the evidences of clinical PCOS. A questionnaire on reproductive history was completed and the waist circumference, weight, height and BP were measured for each participant. Biochemical tests were performed in both groups, but hormonal measurements were requested only for PCOS group.
Results : The prevalence of PCOS was high (about 8%) among subjects. Patients with PCOS had significantly lower age at the onset of diabetes, higher BMI and waist circumference. The differences in BP, serum TG, HDL, LDL, cholesterol and HbA1c were non – significant between 2 groups and insulin resistance is more.
Conclusion : PCOS is prevalent in diabetic women and Insulin resistance is more likely in those with both PCOS and T2DM resistant than whom with diabetes alone. Emphasis on reducing insulin resistance may be of benefit to achieve a better diabetes control in these patients.

Abstract
Background: Leptin is a peptide strongly correlated with adiposity and is a potential determinant of obesity and its complications. The aim of this study was to evaluate the correlation between serum leptin levels and different anthropometric indices among obese women.
Methods: This analytical descriptive study consisted of 106 women with different grade of obesity (BMI ³ 25 kg/m2) and 38 women with normal weight (BMI ≤ 25 kg/m2).serum leptin and glucose levels were measured via enzyme immunoassay and glucose oxidase methods respectively.
Results: The mean (± SE) serum leptin concentrations in apparently healthy women with normal weight ,overweight, obese grade I, and obese grade II were 6.88 ± 0.56, 39.30 ± 1.73, 46.60 ±1.04, and 48.22± 3.31 ng/ml respectively. There was a dramatic increase in serum Leptin concentration when the BMI was increased. There was statistically significant differences between all groups in serum leptin concentration (P<0.001). There was a direct and significant correlation between serum leptin concentration and BMI in obese subjects (r= 0.736, P< 0.001). There was no significant correlation between leptin with age, and leptin with WHR neither in normal weight group nor in different grades of obesity groups.
Conclusion: Our findings showed that the serum leptin levels continuously raised with increasing degree of obesity and among different anthropometric indices serum leptin concentration has significant correlation with BMI.

Abstract
Background: Resistin, an adipocyte secreted factor, has been suggested to link obesity with type 2 diabetes and insulin resistance in rodent models but its relevance to human diabetes remains uncertain. The aim of this study was to investigate the relationship between serum resistin concentrations with insulin resistance and obesity indices in type 2 diabetes and non-diabetic obese subjects.
Methods: As a case- control study 35 obese subjects with type 2 diabetes (age, 44.60 ± 6.39yr BMI, 34.23±3.92 kg/m2) and 35 obese non-diabetics (age, 43.14±9.13yr BMI, 35.54 ± 4.07 kg/m2) are recruited. Fasting lipid profile was measured by enzymatic methods. NycoCard HbA1c Kit was used to measure HbA1c.The Serum resistin, insulin and glucose levels were measured by an enzyme immunoassay using a commercially available kit and glucose oxidase methods respectively. The insulin resistance index was calculated from fasting glucose and insulin by the homeostasis model assessment (HOMA-IR) formula.
Results: The mean of insulin resistance index (HOMA-IR), HbA1c, diastolic blood pressure, triglyceride and fasting glucose in diabetics were significantly higher than non-diabetics subjects (P<0.05). Serum resistin concentrations were not different between diabetics and non-diabetics obese subjects but were significantly higher in women as compared to men (8.15±4.40 vs. 5.97±2.31 in non-diabetic) and (7.46±3.98 vs. 5.51±3.98 in diabetic) in both groups. Serum resistin was not significantly related to variables measured in both groups. In control group only, we observed a significant and negative correlation between diastolic blood pressure and resistin (r = -0.381 P = 0.024).
Conclusion: Serum resistin concentrations were not significantly different between type 2 diabetes and non-diabetic obese subjects and resistin is unlikely to be a major link between obesity and diabetes in humans.

Abstract
Background: Type 2 diabetes mellitus is the most common type of diabetes which is triggered by various factors such as obesity, hyperlipidemia, hypertension, dietary habits and inheritance. With respect to geographic variation of diabetes prevalence, it is important to know the risk factors regionally.
Methods: As a case-control study, we looked for important risk factors of diabetes in our region. This study consisted of 400 individuals in case group and 400 individuals in control group. All these anthropometric measurements were calculated by standard methods. Blood samples taken from two groups were studied for TG, FBS, Cholesterol and HbA1c. Data are reported as the Mean±SD. P<0.05 was considered as statistically significant.
Results: There was no significant difference between two groups about mean age and sex ratio. Statistically significant difference were found for central obesity, hyperlipidemia, hypertension, polycystic ovarian syndrome (PCOS) and positive family history of diabetes in both groups (P<0.05).
Conclusion: The results showed that central obesity, hyperlipidemia, hypertension, PCOS and positive family history of diabetes are important risk factors of diabetes mellitus in Shiraz. In concordance with the results of this study, screening programme for that risk factor of diabetes in this region is suggested.

Abstract
Background: Adiponectin is an adipose tissue-derived hormone that low levels of this hormone are associated with obesity, insulin resistance, and type 2 diabetes. The aim of this study was to compare the serum levels of adiponectin in diabetic and non-diabetic obese individuals.
Methods: As a cross-sectional study 35 obese individuals with type 2 diabetes mellitus and 35 non-diabetic obese subjects were enrolled. Two groups were matched for age, gender and body mass index. Fasting lipid profile was measured via the enzymatic methods. The NycoCard HbA1c Kit was used to measure HbA1c.The Serum Adiponectin, insulin and glucose levels were measured via an enzyme immunoassay, using a commercially available kit and glucose oxidase methods, respectively. The HOMA and QUICKI indices were used to determine insulin resistance and insulin sensitivity, respectively.
Results: The mean of insulin resistance index (HOMA-IR), HbA1c, diastolic blood pressure, triglyceride and fasting glucose in diabetes were significantly higher than non-diabetics (P<0.05). The serum Adiponectin levels was significantly lower in diabetes than non-diabetics (15.74±6.70 vs. 21.52 ± 9.35) and was significantly higher in women than men (19.38 ± 7.33 vs. 12.68 ± 4.28) among diabetic and (24.63 ± 10.52 vs. 17.83 ± 6.21) among non-diabetics groups.
Conclusion: type 2 diabetes mellitus is associated with low serum adiponectin concentrations and probably adiponectin involved in the pathophysiology linking obesity to type 2 diabetes.

Abstract
Background: The relationship between diabetes and serum insulin and Zinc (Zn) levels is complex with no clear cause and effect relationships. Since Zn plays a clear role in the synthesis, storage and secretion of insulin as well as conformational integrity of insulin in the hexametric form, the decreased Zn, which affects the ability of the islet cell to produce and secrete insulin, might then compound the problem, particularly in type 2 diabetes. The aim of this study was to determine the changes of plasma Zn in patients with type 2 diabetes mellitus and healthy control in Shiraz city.
Methods: As a case-control study, we determined the serum Zn levels by atomic absorption spectrophotometer, blood HbA1c levels with columnar chromatographic method and Glucose, by enzymatic colorimetric method in auto analyzer. Data are reported as the Mean±SD and P<0.05 was considered as statistically significant
Results: Results of this study revealed that levels of Zn in serum of diabetic patients is lower than in the healthy control in Shiraz city (P<0.05).
Conclusion: With respect to the result of this study, dietary educations about consuming enriched Zn foods such as sea foods and corn in diabetic patients is necessitated.

Abstract
Background: CoQ10 is a lipid-soluble and a powerful antioxidant. Decreased level of this antioxidant
was reported in many conditions like vascular, diabetes, high blood pressure and coronary artery
diseases. With regards to increased oxidative stress in diabetes and its role in the development of high
blood pressure, this study aimed to examine the effect of Q10 supplementation on blood pressure level
and its relation to nitric oxide metabolites (NOx) level in type 2 diabetic patients.
Methods: In this 12-week randomized controlled trial, T2D subjects received either placebo or
coenzyme Q10 (100 mg twice a day). Anthropometric measures, blood pressure, biochemical analysis
including NOx level, fasting blood glucose, glycosylated hemoglobin (HbA1c) and lipid profile were
evaluated at the beginning and after the intervention.
Results: The intervention resulted in a significant improvement in systolic blood pressure
(115.3±27.61 versus 118.2±12.6 mmHg), diastolic blood pressure (77.1±8.22 versus
80.3±12.11mmHg), NOx (Pvalue=0.014) and HbA1c. Moreover Q10 supplementation resulted a
significant decrease in elevated levels of cholesterol.
Conclusions: In conclusion, CoQ10 supplementation (200 mg/day) for 12 weeks, significantly
decreased systolic and diastolic blood pressure, NOx, HbA1c, total cholesterol and LDL-C in type 2
diabetic patients.

Abstract
Background: Health locus of control is an important variable in diabetes. The aims of the present study were to investigate the role of health locus of control in predicting psychosocial adjustment to illness and compare psychosocial adjustment to illness and dimensions of health locus of control among male and female type 2 diabetic patients.
Methods: One hundred and eighteen patients were recruited via convenience sampling method from type 2 diabetic patients who were referred to the Shahid Motahari diabetes clinic in Shiraz. The participants filled Multidimensional Health Locus of Control (MHLC) and Psychosocial Adjustment to Illness Scale (PAIS).
Results: The results indicated that there were significant positive correlations between psychosocial adjustment to illness and internal health locus of control (r= .30, P &le .001) and God health locus of control (r= .18, P &le .05). Internal health locus of control (&beta= .28, P &le .01) significantly predicted psychosocial adjustment to illness. There were significant differences between male and female diabetic patients on the basis of chance health locus of control. Female patients got higher scores on chance health locus of control. Moreover, there were no significant differences between male and female diabetic patients on the basis of psychosocial adjustment to illness.
Conclusion: The findings highlighted that internal health locus of control and God health locus of control play significant role in psychosocial adjustment to illness. Therefore, it is recommended that psychologists and clinicians take the dimensions of health locus of control into considerations in the treatment of psychological problems of diabetic patients.

Abstract
Background:Diabetes mellitus is regarded as a major health problem due to its complications that these,nonetheless could be prevented or delayed with changes and modifications in the patients’ behavior and dietby understanding their beliefs..The objective of this study was to explore the utility of the Theory of PlannedBehavior (TPB)and complications of diabetes perceived risk to find modifiable diabetes-related believes inorder to make behavior changes feasible.
Methods: The presentdescriptive-analytical cross sectional study was conducted in Semirom Diabetes Clinicbased on the TPBand complications of diabetes perceived risk, using a self-administered questionnaire. Atotal of 154 diabetic patients without complications of diabetes were participated in the study. Measured variables were patients’ attitude, subjective norm, perceived behavioral control, complications of diabetesperceived risk, intention to eat a healthful diet and nutritional style. Structural equation modeling was used toanalyze data.
Results:The results revealed that the TPBand complications of diabetes perceived risk fitted the data
acceptably well among the Type 2 diabetes and within dietary behavior. Perceived behavioral control,
subjective norm, complications of diabetes perceived risk and intention to eat a healthy diet were related tohealthy diet behavior. No relation was found between attitude and intention to eat a healthy diet.
Conclusion:The TPB and complications of diabetes perceived risk is a useful theory in determining
intentions of diabetic patients’ and their adherence to healthy diets. TPB and complications of diabetes perceived risk forms a framework for promoting dietary practice among Type 2 diabetic patien

Abstract
Background: The purpose of this study was the investigation effect of gender on plasma glucose, insulin and insulin resistance index in response to acute endurance activity and subsequent recovery periods in healthy individuals.
Methods: Eight females and seven males 20-30 years old (females 22.37±1.50 and men 23.42±1.27 years old, female weight 55.50±8.14 men and 79.85±15.16 kg, women height 160.12 ± 4.18 men and 179.71±6.57 cm) voluntarily participated in this study. Subjects performed two control activities during two consecutive weeks. The implementation of the sessions was randomly determined for each subject. Exercise program consisted of 45 min acute endurance at 75% of maximum heart rate on the treadmill and subsequently the subject was in a sitting position for one clock recovery. Four blood samples (6 ml) before and immediately after exercise, as well as 1 and 24 hours after the activity was collected. Two-way analysis of variance for data analysis was used.
Results: Regardless of gender, effects of activity and recovery on plasma insulin and insulin resistance index was significant (p <0.05) but not significant for glucose. Also when the data were corrected by changes in plasma volume, similar results were observed for insulin. Although changes of all factors (glucose, insulin, and insulin resistance) in response to activity session of acute exercise endurance was higher in men than in woman, gender has not significant effect on factors.
Conclusion: acute endurance activity and recovery induce change in insulin resistance index but these changes were not related to gender.

Abstract
Background: Skeletal muscle as an endocrine tissue is involved in the regulation of metabolic activity, production and secretion of hormones including myokines. The aim of the present study was to investigate the effect of eight weeks of aerobic training combined with ethanol consumption on plasma lipid profile and glucose levels, triglyceride content and mayonectin, irisin and leptin gene expression in the gastrocnemius muscle in male rats.
Methods: A number of 32 rats with a weighing average of 200 ± 10 g were divided into four groups control, aerobic training, ethanol with dose of 4 g/kgbw, and ethanol +aerobic training. At the end of the period, values of lipid profile and plasma glucose, the amount of triglyceride of the gastrocnemius muscle and the relative levels of mayonectin, irisin and leptin gene expression were evaluated. Data were analyzed using two-way ANOVA.
Results: The plasma triglyceride levels in the aerobic training and ethanol+aerobic training groups were significantly decreased compared to the control group (P≤0.05). The gastrocnemius muscle triglyceride values were significantly increased in the ethanol +aerobic training (P≤0.0001) and aerobic training groups (P≤0.01) compared to the control group. The results showed that aerobic training significantly increased myonectin gene expression in aerobic training group (P≤0.05), but the expression of irisin and leptin genes did not change significantly in different groups.
Conclusion: Aerobic training during the eight-week was able to improve lipid content, especially plasma triglyceride and skeletal muscle triglyceride, and possibly regulate body metabolism by altering the levels of myokines, especially myonectin.

Abstract
Background: A novel nanocomposite-modified electrode based on reduced graphene oxide (rGO) decorated with crown-ether and gold nanoparticles (GNPs) on the surface of a glassy carbon electrode (GCE) was fabricated to investigate 5-HT determination.
Methods: The morphology of nanocomposite was characterized by scaning electron microscopy (SEM). Diabetic zebrafish was obtained by overfeeding via glucose. 5-HT was successfully determined in the presence of dopamine (DA), ascorbic acid (AA), urea, glucose, and L-tryptophan (L-Trp) by using electrochemical methods.
Results: The nanocomposite exhibited satisfactory electrochemical catalytic activity for 5-HT determination using square-wave voltammetry (SWV). The electrochemical behavior of 5-HT at the nanocomposite/GCE displayed reasonable oxidation current and potential. The limit of detection (LOD) of 5-HT obtained from the real samples, containing the control and diabetic group by using the proposed system and HPLC method, was calculated to be about 0.3 and 0.1 µg/L, respectively. The prposed system also demonstrated high selectivity, reasonable sensitivity, and good stability and reproducibility for 5-HT sensing. The nanocomposite was applied for the determination of the biomarker 5-HT in the diabetic and control groups of zebrafish and displayed excellent recoveries about 93 and low relative error about 3% while compared with standard method.
Conclusions: It seems that the 5-HT level can be used for earlier diagnosis of diabetes.

Abstract
Background: The aim of the present study was to investigate the simultaneous effect of resistance training and stem cell injection on the levels of some indicators of skeletal muscle apoptosis in STZ-induced diabetic male rats.
Methods: In this study, 30 rats were randomly divided into 5 groups. Rats in the diabetic group and the diabetic group + stem cell injection had a total of 17 sessions of resistance training for 5 weeks. The training period for rats with this type of training was 3 days, which was done 48 hours before STZ injection. Western blotting was used to evaluate the changes in Caspase7 and caspase3. The data were analyzed using two-factor analysis of variance test with SPSS software version 19 at a significance level of α≤ 5%.
Results: The results of the present study showed that there was no significant difference between the mean of caspase3 in the resistance training group with simultaneous injection of stem cells and the training group. Also, resistance training with simultaneous injection of endothelial stem cells, compared to resistance training or injection alone, led to a significant reduction in Caspase7 expression in skeletal muscle tissue of diabetic rats.
Conclusion: Based on the results of this study, it can be stated that resistance training or injection of endothelial progenitor cells can stimulate apoptosis in skeletal muscle.

Abstract
Background: Fat mass and obesity-associated gene (FTO) is directly associated with increased risk of obesity and type 2 diabetes mellitus (T2DM). The purpose of this study was to investigate the effect of 12 weeks of high intensity interval training (HIIT) on FTO expression of subcutaneous fat tissue in T2DM rats.
Methods: In this experimental study, twelve males Wistar rats (220±10 g) with T2DM induced by streptozotocin-nicotinamide injection were randomly divided into exercise (n=6) and control (n=6) groups. The training group performed the HIIT protocol on a treadmill for 12 weeks and 5 days per week. FTO expression in subcutaneous fatty tissue, blood glucose level, insulin and insulin resistance were measured 48 hours after the last training session. Data were analyzed by independent T test at P< 0.05.
Results: Blood glucose level, insulin resistance and FTO expression in fat tissue decreased significantly in training groups compared to control group after the exercise intervention (P˂0.05). Serum insulin increased significantly in training groups compared to control group (P˂0.05).
Conclusion: It seems that HIIT can decrease glucose, insulin resistance and FTO expression of fat tissue of T2DM rats. Improved glycemic control in diabetic rats might be attributed to reduced FTO expression in response to HIIT.
