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: Diabetes is a kind of metabolic disorder characterized by hyperglycemia, caused by defect in insulin function, secretion or both. In chronic hyperglycemia different tissues and organs, such as thyroid gland underwent histophysiological alterations. The aim of the present study was to compare the effects of type 1 and type 2diabetes on the serum levels of biochemical factors and histological changes in the thyroid gland in male Wistar rats.
Methods: After induction of type 1 diabetes (Alloxan 135 mg/kg BW) and type 2diabetes (10% fructose administrated through drinking water for 8 weeks) all rats were kept for 2 months. Blood samples were collected at the beginning and in the middle and at the end of experiment for biochemical factors analysis. After that, the thyroid gland of all rats were removed and processed for histological preparation. Then the HE stained sections were examined for thyroid gland volume and follicular surface density measurements, using Cavalieri’s Principle and stereological method, respectively.
Results:The results showed an increase in surface density and a decrease in thyroid volume in type 1 diabetic and type 2 diabetic groups, when compared with control. Furthermore, in type 1 diabetic group, the Triglycerid and Cholesterol levels increased and LDL level decreased, while in type 2 diabetic group, LDL and HDL levels slightly decreased. These results reveal that type 1 and type 2 diabetic conditions probably cause hypo- and hyper activity of thyroid gland, respectively.

Abstract
Background: Myokines released from skeletal muscle have multiple metabolic and hypertrophic effects. On the other hand, one of proposed pathways for effects of exercise training on metabolic diseases is calcineurin signaling pathway. With considering to relation between interleukin-6 (IL-6) and calcineurin, the purpose of this study was to investigate whether the resistance training has an effect on mRNA expression of IL-6 myokine and regulator of calcineurin 1(RCAN-1) in skeletal muscle of diabetic rats.
Methods: Thirty two Rats randomly were divided into the control, training, diabetic control and diabetic training groups. Diabetes induced by streptozotocin (STZ). Training groups performed the 17 sessions of resistance training. The IL-6 and RCAN-1 mRNA expression were measured in Soleus skeletal muscle using the Real-time PCR method. Two-way analysis variance was used for statistical analysis. Also, Statistical significance was set at p<0.05.
Results: The results of this study showed that the mRNA expression of RCAN-1 was increased with resistance training in skeletal muscle of training groups (P<0.05). Also, diabetes was decreased expression of RCAN-1 in skeletal muscle of diabetic groups (P<0.001). Moreover, resistance training was increased mRNA expression of IL-6 in skeletal muscle (P=0.08).
Conclusion: With considering to our results, resistance training with direct effects on skeletal muscle could regulate calcineurin pathway in diabetes and concurrent increase in expression of IL-6 myokine. It seems that activation of this signaling pathway with resistance training could maintain skeletal muscle mass in diabetes.

Abstract
Background: This review study aims to shade light on the effects of carrying out interventions and policies in order to reduce the incidence and prevalence of non-communicable diseases (NCDs) and their behavioral risk factors (i.e., unhealthy diet, insufficient physical activity and smoking) and strategies and approaches to reduce their attributed burden.
Method: In this research, the documents and reports available in the Ministry of Health, developed action plans, recommendations of national and international organizations, evidence gathered from monitoring and evaluations and the "National Action Plan and Control of Non-Communicable Diseases and Related Risk Factors in the Islamic Republic of Iran, 2015-2025" were investigated with respect to each of the three main risk factors of NCDs, including unhealthy diet, insufficient physical activity, and smoking (harmful consumption of alcohol has been reviewed in another article). Each risk factor has been discussed separately in the sections describing the current situation, policies and implemented interventions, findings, and future plans.
Results: The implemented interventions and policies to achieve the goals stated in the "National Action Plan and Control of Non-Communicable Diseases and Related Risk Factors in the Islamic Republic of Iran, 2015-2025" in the field of unhealthy nutrition, resulted in revising the food standards. Interventions in the field of physical activity have caused a 1.5% reduction in the relative prevalence of sedentary behavior in the society. Our research also revealed that interventions in the field of tobacco consumption have led a total decrease of 7.44% among Iranian people over 18 years of age, but a decrease in the use of hookah is not recorded, and its consumption has increased by 28% in 2021 compared to 2011.
Conclusion: According to the findings, the goals stated in the aforementioned document have not been fully achieved, so new interventions and policies should be used by those involved.
