Background: Diabetes type 2 is one of the most prevalent reasons of Hyperglycemia. Different areas experience varying degrees of epidemic intensity. Diabetes is one of the most important causes of death and disability in most countries and imposes heavy financial burdens on people and governments. Although much research has been conducted on its prevention and treatment. It has been recognized as a hereditary disease, the genes causing it or its mode of inheritance are not yet known. Because of the significant role they play in metabolism of glucose, several genes have suggested, but the main cause of the disease has not yet been identified. Our objective is to investigate the epidemic aspects of the hereditary diabetes in people aged 20 years and over.
Methods: A cross sectional study was conducted on 14687 subjects, in the urban setting of east Tehran between 1379 and 1380. Of 407 families, 180 agreed to and completed related questionnaires and underwent the necessary tests 180 diabetic families, with at least one member suffering from diabetes type 2, were studied closely in order to clarify the degree of spread and family background. Analysis was performed using Chi Square and t-test.
Results: Of 1612 subjects, 497 had diabetes, including 802 women and 792 men (p<0. 001). Most of the diabetics (approx. 79%) were between the ages of 41-70 years old with the highest (55.3%) and lowest (6.2%) rates in the age groups of 51-60 and 20-30 years respectively. Diabetes was more prevalent among siblings with 53% in comparison to the prevalence among offsprings-44%. The prevalence of Diabetes type 2 in first-degree relatives was more frequent between sister and brother (52.7%), followed by that between father and daughter (36%). Conclusion: It is recommended that the related authorities implement strategies, including screening of families, with a view to identify those at risk and reduce related complications.

Background: Type 2 diabetes is a hereditary disease but the inheritance and responsible genes have not been clearly clarified yet. According to the most studies, diabetes is one of the most common causes of mortality and morbidity in populations. Diabetes occurs in 30% of first degree family members of diabetic patients, But most people are not aware of their disease.
Methods: We studied first degree relatives of type 2 diabetes and screened them for diabetes, IFG and IGT.174 families(1556 people) of Tabriz residents were studied, among them 1232 persons grater than 30 years were alive and FBS and OGTT were done in this group .
Results: According to this study, 1232 persons were alive and 324 persons had died and DM was found in 343 (27.9%) and 82 (25.3%) of them respectively. We found 179 (14.5%) persons with IFG and 89 (7.2%) with IGT.The percent of diabetes in offspring and siblings were 32.9% and 22.1% respectively. The majority of patients had 41 – 50 years old. Risk of diabetes among offspring who had diabetes in both parents was more than the ones who had diabetic father or mother. In this study, women with diabetes were more than men (32.4% vs. 22.2% respectively). The prevalence of Diabetes type 2 in first-degree relatives was more frequent between sister and brother (41.95%), followed by that between father and son (10.9%).
Conclusion: Prevalence of diabetes in most populations is 8 – 10 %. If diabetes occurs in someone, risk of development of diabetes will increase to 30% in their family members. Therefore, screening must be done in all family members of diabetic patients to recognize the problem and to prevent from diabetes complication.

Background: Diabetes mellitus is the most common human metabolic disease. Chronic hyperglycemia and carbohydrate metabolism disorder accompany with plasma lipid and lipoprotein disorder. Cardiovascular disease is one of the macro vascular complications of diabetes type 2 which leads to high morbidity and mortality. Dyslipidemia is one of the major risk factors of cardiovascular diseases in diabetic patients. High TG and low HDL-C levels are the most prevalent type of dyslipidemia. Low levels of HDL-c considered as a risk factor for cardiovascular diseases. Methods: In this study 40 type 2 diabetic patients (13 male - 27 female) were included. Lovastatin and Gemfibrozil were recommended separately for 2 months and HDL-C were measured at the baseline and after taking drugs. In all patients BS, TG and TC at the baseline before and after these drugs were normal and so were not any change in their diet. Laboratorial findings gathered and analyzed. The relationship between increase level of HDL and decrease of TC with taking Lovastatin and Gemfibrozil were studied. Results: The averages of TC and HDL-C before taking drug as linear were 36.5mg/dl and 174.56 mg/dl and after taking Lovastatin as linear were 43.3 mg/dl and 150.44 mg/dl. The average of TC and HDL-C after taking Gemfibrozil were 43.33mg/dl and 146.36mg/dl. 18.54 % increase in HDL-C and 13.82% decrease in TC were seen with Lovastatin and 18.54% increase in HDL-C and 16.05% decrease in TC were found with Gemfibrozil. Conclusion: In this study no difference was observed between the effect of Lovastatin and Gemfibrozil in increase of HDL-C (P=0.449). Also there was no difference between the effect of Lovastatin and Gemfibrozil in decrease of TC (P=0.992). The increase of HDL-C after taking Lovastatin had relation with sex and HDL-C increased in females (P=0.006) Also the increase of HDL-C after taking Gemfibrozil had relation with sex and females had more affected (P=0.035).

Background: In this study, using anti-human serum albumin (HSA)-conjugated gold nanoparticles (AuNPs) as an electrochemical label and mobile crystalline material-41 (MCM-41)–polyvinyl alcohol (PVA) mesoporous nanocomposite as an immobilization platform, a new immunosensor was established. Methods: Field emission scanning electron microscopy (FESEM), cyclic voltammetry (CV), and differential pulse voltammetry (DPV) have been applied to determine the physicochemical and electrochemical properties of this hybrid film in immunosensor development. Results: A suitable attachment between HSA and MCM-41 and also a thick layer deposition of MCM-41–HSA–PVA film onto the electrode surfaces was observed by FESEM. DPV was employed for quantitative determination of antigen. Conclusion: In optimal conditions, this immunosensor could detect HSA in a high linear range (0.5– 200 µg ml -1 with a low detection limit of 1 ng ml -1 . This new strategy showed acceptable reproducibility, stability, and reliability and could also be applied to detect the other antigens.

Background: Irisin was identified as a myokine secreted by exercise which plays an important role in energy metabolism and regulation of metabolic diseases such as diabetes. The aim of the present study is to investigate the effects of high intensity interval exercise (HIIE) and moderate intensity continuous exercise (MICE) on serum irisin and Subcutaneous UCP-1 in diabetic male rats.

Methods: In this study, 29 diabetic Wistar rats (12 week- age, 220-240 gr- weight) were assigned to 5 groups: immediately and 2 hours after high intensity interval exercise (HIIE0, HIIE2), immediately and 2 hours after moderate intensity continuous exercise (MICE0, MICE2) and control (C). Both MICE groups performed on the treadmill with intensity 60-65% vo2max for 40 minutes and both HIIE groups with intensity 90-95% vo2max in the 12 interval-one minute period and 1 minute rest intervals. ELISA was used to measure serum irisin and subcutaneous fat UCP-1. One-way ANOVA and Tukey post hoc test has used to data analysis, the level of significance has been considered at P≤0/05.

Results: Data analysis showed serum irisin levels in the HIIE0 group and subcutaneous fat UCP-1 in the HIIE2 significantly increased compared to the control group (p˂0/05). However, there was no significant difference between other research groups (P>0/05).

Conclusion: It seems high intensity of exercise had important roles in significant changes of serum irisin levels and subcutaneous fat UCP-1in diabetic rats.

Background: The purpose of this study was to compare effects of three combined aerobic-resistance exercise training protocols with different intensities on metabolic control and Visfatin levels in men with type 2 diabetes.
Methods: 43 male patients with type 2 diabetes were randomly divided into 4 groups (three combined aerobic-resistance exercise training groups 1, 2, 3 and control). Training groups performed combined aerobic-resistance exercises for 12weeks, 3 times a week with given intensities )group 1:resistance 50-60% one repetition maximum- aerobic 70-80%maximum heart rate, group 2:resistance 60-70% one repetition maximum- aerobic 60-70% maximum heart rate and group 3:resistance 70-80% one repetition maximum- aerobic 50-60% maximum heart rate). Blood sampling to determine the levels of Visfatin, insulin, HbA1c, fasting glucose before and after 12weeks, were conducted.
Results: Visfatin levels and HbA1c in all training groups and fasting glucose in 2 combined training groups significantly decreased compared with control group (P<0.05). Vo2max was significantly increased in all training groups (P<0.05). No significant difference were observed between groups in body weight, Body mass index, fat mass, insulin levels and resistance insulin.
Conclusion: 12 weeks of combined aerobic-resistance exercise training protocols with were executed intensities through decreasing Visfatin and HbA1c levels and improving aerobic capacity could be helpful in patient with type 2diabetes. In addition to the above benefits, combined exercise training protocols of with intensity of 60-70% maximum heart rate–intensity 60-70% repetition maximum due to reducing fasting blood glucose could give greater benefits to patients.

Background: Obesity and type 2 diabetes can impair the function of important cellular pathways. Activation of the mTOR pathway results in regulation of the SREBP1 protein for metabolism and regulation of adipose tissue. The aim of this study was to investigate the effect of 4 weeks of high intensity interval training on the content of mTOR and SREBP1 in adipose tissue of type 2 diabetic rats.
Methods: In this experimental study, 12 to 2-month-old male Sprague-Dawley rats weighing 300 20± 20 g were selected and after being diabetic by induction of STZ and nicotine amide, randomly divided in two groups, diabetic training (6 rats) and diabetic control (6 rats). Exercise group training 4 days a week for 4 weeks according to the training HIIT; The control group had no exercise program. Independent t-test and dependent t-test were used for data analysis.
Results: There was no significant change in mTOR protein content (p=0.12); But the SREBP1 protein content (p=0.001) increased significantly. The weight of control group (P=0.0001) and HIIT group (P=0.010) showed a significant increase. Blood sugar in the control group also increased significantly (P=0.0001), but HIIT mice did not show a significant change (P = 0.14).
Conclusion: 4 weeks of HIIT training did not significantly change weight, blood glucose and mTOR protein content. But it did increase the SREBP1 content, so factors such as duration and intensity of training should be adjusted in order to achieve the best results when administering HIIT.

Background: Physical activity and exercise training are known as an integral part of weight management and control in overweight or obese people. The aim of this study was to compare the effect of high intensity interval training (HIIT) and intense resistance training on asprosin and C1q/tumor necrosis factor related protein1 (CTRP1) serum levels in overweight and obese men.
Methods: In this semi-experimental study, 31 overweight and obese men were randomly divided into three groups: HIIT training (n=10), intense resistance training (n=11) and control (n=10). The subjects of the experimental groups performed HIIT exercises and intense resistance exercises three times a week for nine weeks. Before and after the intervention, blood samples were taken to measure the serum concentration of asprosin and CTRP1 from the subjects. Analysis of covariance test was used to analyze the data and the significance level was considered as p_value less than 0.05.
Results: The concentration of asprosin in the HIIT group (p=0.013) and intense resistance training (p=0.042) decreased significantly compared to the control group. No significant difference in CTRP1 concentration was observed between groups. However, the concentration of CTRP1 in the HIIT group decreased significantly in the post-test compared to the pre-test.
Conclusion: HIIT training and resistance training in overweight and obese men led to a decrease in asprosin levels. Considering the changes in asprosin, CTRP1 and other anthropometric indicators and lipid profiles, HIIT training seems to have a better efficiency in overweight and obese men.

Background: Despite the increased use of complementary medicine by diabetic patients, there is no clear estimation of complementary and herbal medicine use by these patients in Iran. This study was conducted to investigate the uses of herbal medicine among patients with type II diabetes in Yazd, Iran, in 2022.
Methods: A cross-sectional study was carried out on 633 patients with type II diabetes referred to the Diabetes Research Center in Yazd City from June to September 2022. A questionnaire-based theory of planned behavior developed and validated by the researcher was used for data collection. In addition to demographics and disease-related information, the instrument included questions about using herbal medicine used. Descriptive statistics, Chi-square, Fisher's exact, and linear regression tests were used to analyze the data.
Results: The most common herb used was cinnamon (34.7%). The majority of patients used herbs daily (56.9%). Using herbal medicine was significantly associated with Attitude (r= 0.48, p< 0.001) Subjective norm (r= 0.39, p< 0.001), perceived behavior control (r= 0.38, p< 0.001) and intention (r= 0.4, p< 0.001). Constructs of the theory of planned behavior 73% predicted intention to use herbal medicine. Subjective norm structure had the highest predictive power of intention to consume herbal medicine (ß= 0.49, p< 0.001).
Conclusion: Subjective norm is the most predictor of intention to use Herbal medicines in patients with diabetes. Therefore, it is very important to pay attention to the beliefs, customs, and culture of the surrounding community in the correct self-management of disease control and the use of effective drug control.

Background: The effects of regular exercise on miRNA profile and oxidative stress indices are less known. The aim of this study was to investigate the changes in expression of  miR-17 and oxidative stress indices in overweight and obese women following high-intensity functional training.
Methods: In this semi-experimental study, 22 overweight and obese women were randomly divided into two groups of high-intensity functional training (n= 10) and control (n= 12). The subjects of the training group performed high-intensity functional exercises 3 times a week for 8 weeks and intensity of rating of perceived exertion≥7. Before and after 8 weeks, blood samples were taken to measure expression of miR-17 gene, malondialdehyde (MDA), superoxide dismutase, glutathione peroxidase (GPx) and total antioxidant capacity (TAC). Analysis of covariance test was used to analyze the data.
Results: After eight weeks of high-intensity functional training, expression of miR-17 in the experimental group significantly decreased compared to the control group (P= 0.001). After eight weeks of high-intensity functional training, TAC (P= 0.0001), GPX (P= 0.007) and SOD (P= 0.001) increased significantly in the experimental group compared to the control group. No significant change was observed in MDA (P= 0.778).
Conclusion: The results of the present study showed that eight weeks of high-intensity functional training may lead to the reduction of miR-17 expression and the improvement of oxidative stress indices and antioxidant enzymes, which may be effective in improving metabolic indices and obesity complications.

Background: gestational diabetes is one of the most common diseases during pregnancy, and health literacy of pregnant mothers plays an important role in the prevention and management of the disease. The study aimed to examine and compare the health literacy of pregnant women with gestational and non-diabetic diabetes visiting health centers in the city of Yazd in 1402.
Methods: This descriptive-analytical study was conducted on 206 diabetic and non-diabetic pregnant women; the cluster health center sampling method and pregnant mothers were randomized sampling method. The data was collected using a health literacy questionnaire and analyzed using Chi Square tests, independent t-Tests and variance analysis.
Results: The results of the study showed that the average health literacy score of non-diabetic pregnant mothers (74.26 ± 13.75) was significantly higher than the average health literacy score of diabetic mothers (47.527 ± 21.06) (P< 0.001) and the percentage of diabetic women with insufficient health literacy was reported as 69% and 3.9% of non-diabetic women, which indicates a significant difference in the level of health literacy between diabetic and non-diabetic pregnant mothers (P< 0.001). In addition, diabetic mothers showed an inverse relationship between health literacy and the number of pregnancies and their children, while this trend was not observed in non-diabetic mothers (P< 0.001).
Conclusion: The results of this study indicate that non-diabetic pregnant women have higher health literacy than those with gestational diabetes, highlighting the importance of enhancing health literacy in this group of mothers. Additionally, the strong relationship between health literacy and the mother's diabetes status underscores the need for targeted programs and training to improve health literacy among diabetic pregnant women. Therefore, enhancing health literacy can be crucial in better managing gestational diabetes and improving maternal health outcomes.
