Abstract

Background: Zinc-Alpha 2-Glycoprotein (ZAG) has recently been implicated in the regulation of adipose tissue metabolism due to its negative association with obesity and insulin resistance. The purpose of this study is to investigate the effect of eight weeks HIIT on level of ZAG in plasma and adipose tissue in type 2 diabetic male rats.
Methods: Twenty one male rats were divided into the three groups of sham control (healthy), control (diabetic), and interval training (diabetic with training). The training group received 8 weeks of training sessions each with 5-12 repetitions of high intensity training for 15-30 seconds at the speed of 27-34 meters per second on a treadmill followed by one minute of active rest. Twenty four hours after the training session blood and body fat samples were taken to measure ZAG levels. The data was analyzed using one-way ANOVA and Tukey’s post hock test at the significance level of 0.05 (P<0.05).
Results: There were significant differences between the sham control and the control with respect to ZAG contents in adipose tissue, which was lower in the diabetic control group (P<0.001). Moreover, significant differences in ZAG contents of adipose tissue were also observed between the sham control and the group receiving the training, with the sham control having higher ZAG contents in adipose tissue (P<0.005). The eight-week HIIT significantly increased the amount of secreted ZAG in adipose tissue compared to the control diabetic group (P=0.003). No significant differences were recorded between the groups in ZAG plasma levels.
Conclusion: The HIIT increased ZAG content in the adipose tissue of the male diabetic rats. This can reduce insulin resistance in type 2 diabetes.

Abstract

Background: The aim of this study was to investigate the effect of 12 weeks of high intensity training on IL-
6, GLP-1 and lipid profiles in type 2 diabetic patients
Methods: 80 participants (40-50 years old) volunteered to participate in the study and divided into eight groups (four groups of severe periodic exercises and four uncontrolled control groups). Blood samples were collected and analyzed for measuring IL-6, GLP-1, lipid profile and glycemic index before and after weeks 4, 8 and after the training program.
Results: After 12 weeks of training, the effect of time and interaction between time × group on GLP-1 and IL-6 variables was statistically significant. Also, there was a significant difference between groups based on 12 weeks of training in these indices. Lipid profile was significantly improved in type 2 diabetic and glycemic control in obese and non-diabetic groups that had 12 weeks of high intensity interval training.
Conclusion: Overall, high intensity interval training, through changes in various mechanisms, lead to improvement in lipid and glycemic disorders, inflammation and appetite in obese people with type 2 diabetes. Hence, according to the findings of the study, researchers suggest that performing high intensity interval training can lead to significant improvements in obese subjects (with and without type 2 diabetes).

Abstract

Background: The purpose of this study was to compare the effects of a 12 weeks interval training with high and moderate intensity on PGC-1α of skeletal muscle in type 2 diabetic male rats.
Methods: 40 male rats were divided into two groups: High fat diet (HFD) (n=32) and standard diet (C) (n=8) for 10 weeks. After inducing type2 diabetes via STZ, 8 diabetic rats (D) and 8 rats in group C rats sacrificed and the remaining 24 Rats were randomly assigned to three groups of diabetic control (DC), moderate intensity interval training (MIIT) and high intensity interval training (HIIT).The MIIT protocol includes 13 bouts of 4-minute activity with equivalent intensity of 60-65% vo2max  and the HIIT protocol includes 10 bouts of 4-minute activity with equivalent intensity of 85-90% vo2max with 2 minute active rest periods that was applied for 12 weeks, 5 sessions per week. Western Blot method was used to measure PGC-1α protein levels.
Results: The results showed that PGC-1α protein levels were significantly lower in the D group compared to the HC group. In contrast, the HIIT protocol resulted in an increase in protein levels of PGC-1α compared to DC2 group. While MICT had no significant effect on protein levels of PGC-1α (P <0.05). Also, there was no significant difference between the two training groups (P<0.05).
Conclusion: It seems that the intensity of interval training plays an important role in the regulation of skeletal muscle PGC-1α and possibly mitochondria biogenesis in type 2 diabetic rats.

Abstract

Background: Nesfatin-1 is an adipokine that released by adipose tissue and participated in the regulation of insulin activity and glucose metabolism. The aim of this research is the investigation the effect of aerobic training and walnut consumption on nesfatin-1 and insulin resistance index of women Type 2 diabetes.
Methods: 40 women aged 40 to 50  years old with type 2 diabetes after homogenization based on Bruce test were selected through targeted sampling and they were randomly assigned to four groups of training, walnut, training + walnut and control (each group was 10). The 8-week aerobic training was three sessions per week for 16 minutes with 65% of maximal heart rate in the first week, while in the eighth week it reached 30 minutes with 80% of maximal heart rate. The walnut groups each day replaced 25 to 27 grams of walnuts as part of a diet rich in PUFA fatty acids, replacing one third of total dietary fat. 24 hours before the first session and 48 hours after the last session of the protocol, all subjects received blood samples. The inter-subject inter-analysis variance analysis was used. The significance level was considered as P <0.05.
Results: In the training groups, weight, body mass index, glucose, insulin and insulin resistance decreased significantly and the maximum oxygen consumption and nesfatin -1 increased significantly(P<0.05). 
Conclusion: Aerobic training with this intensity and amount can be recommended as auxiliary treatment for type 2 diabetic women. Walnut consumption with this value did not affect the level of blood glucose, insulin resistance index and nesfatin-1 in type 2 diabetic women. It is recommended that high-dose walnuts be used for effective operation.

Abstract

Background: Diabetes and obesity are associated with a decrease in sexual function and sexual activity due to changes in sex hormones. The purpose of this study was to investigate the Independent and interactive effect of Tribulus terrestris supplementation and resistance training on testosterone, FSH, LH and erectile function in obese men with type 2 diabetes.
Methods: In this quasi-experimental study, 40 obese men with type II diabetes (41.97±8.01 years old, BMI 31.97±1.87 kg/m2) were divided into four groups: 1) Resistance training+ placebo  2) Tribulus terrestris 3) Resistance training+Tribulus terrestris 4) Control. Subjects in the first and third groups performed a Resistance training protocol for 8 weeks. Also, the subjects in the second and third groups received Tribulus terrestris 1000 mg daily (two 500 mg capsules) and the first group received the same amount of placebo. Blood samples and questionnaires were collected in two stages before and after the test to assess the biochemical values and erectile function. Statistical analysis of data was performed using t-test, one way ANOVA and Tukey post hoc test at a significance level of 0.05.
Results: Results showed that erectile, testosterone, FSH and LH values increased significantly in the three groups of resistance training, tribulus terrestris and resistance training+tribulus terrestris (P≤0.05). Also, were observed significant difference in all variables between resistance training+tribulus terrestris group whit resistance training and tribulus terrestris groups (P≤0.05).
Conclusion: It seams that eight weeks of independent Tribulus terrestris Consumption and performing Resistance training increases sexual and erectile function. But it seams, combining these two, causes more sexual and erectile dysfunction in obese men with type 2 diabetes.

Abstract

Background: Type II diabetes is a chronic inflammatory condition that is associated with a combination of genetic and environmental factors. Tumor necrosis factor alpha or TNF-α as an adipocyte cytokine, which affects the signaling pathway of insulin, can contribute to insulin resistance in type 2 diabetes patients. Considering the importance of epigenetic changes in multifactorial diseases, this study aimed to investigate TNF-α promoter methylation in patients with type 2 diabetes.
Methods: This study was performed on 61 patients with type 2 diabetes and 31 non-diabetic patients. The Groups were matched in terms of demographic characteristics. The lipid profiles were measured by standard kits. TNF-α promoter methylation levels were measured by bisulphite treatment method, Nested PCR and sequencing.
Results: There was no association between TNF-α promoter methylation gene promoter and type 2 diabetes in the studied groups. Also, there was no association between TNF-α promoter methylation in diabetic and non-diabetic groups between males and females.
Conclusion: The epigenetic changes in cytokines that contribute to insulin resistance in type 2 diabetic patients seem to be ineffective in peripheral blood samples, and other tissues may need to be investigated in this regard.

Abstract

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.

Abstract

Background: Type 2 diabetes mellitus (T2DM) is the most common type of diabetes that was classically characterized by pancreatic β-cell dysfunction. Changes in circadian patterns is one of the reasons which can increase the occurrence of diabetes. Melatonin is one of the biological molecules which plays an important role in regulating the circadian clock and also an inhibitory effect on insulin secretion in β-cells. The aim of this study was to examine the association between MTNR1B (rs10830962) gene polymorphism and the risk of T2DM.
Methods: Genotyping was carried out in a total number of 208 subjects including 108 patients with T2DM and 100 normal controls using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) which is confirmed by Sanger sequencing method.
Results: The frequencies of CC, GC and GG among cases were 54.63%, 1.85% and 43.52% and in control subjects were 81%, 0% and 19% respectively (P<0.001). Frequency of G allele among diabetic patients was significantly higher than non-diabetics (OR=3.34, CI=2.10-5.36, P<0.001).
Conclusion: Our study showed that rs10830962 polymorphism of the MTNR1B gene can be directly associated with T2DM risk.

Abstract

Background: Autophagy is a new therapeutic strategy aimed at reducing the diabetic abnormalities. While excessive or insufficient autophagic activity during diabetes leads to altered cellular homeostasis. So, aim of the present study was conducted to determine the effect of eight-week high-intensity interval training (HIIT) along with caffeine injection on the levels of some myocardial autophagy-related proteins in diabetic rats.
Methods: In experimental design, fifty male white wistar rats with an age range of 3-2 months  (average weight 250±25 g) were randomly divided into 5 groups of homogeneous 10 rats in each group: Healthy control (C: intraperitoneal injection of saline), Diabetic control (D: high-fat diet combined with a single intraperitoneal injection of streptozotocin, Diabetic with training (D+T: running with intensity at the 85-90% of maximum speed in 5 to 12 bout of 2 min-1; 5 days/week for 8 weeks), Diabetic with caffeine supplementation(D+CA: intraperitoneal injection of pure caffeine at 70 mg.kg-1 5 days/week for 8 weeks), Diabetic with training and with caffeine supplementation (D+T+CA). For evaluate changes in the expression profile of some of the genes associated with autophagy signaling pathway (LC3-II, ULK-1, Beclin1) in the myocardium (left ventricular), based on Western blot analysis will be used. Also, the one-way analysis of variance (ANOVA) and Tukey post hoc test were be used to analyze the data.
Results: The expression of all autophagic proteins in diabetic with trained and non-trained groups was higher than in healthy
group (P≤0.05). On the one hand, the expression of autophagy-related proteins in the trained group with caffeine supplementation was significantly higher than that of the training group without caffeine intake (P=0.001).
Conclusion: The findings of this study suggest that caffeine injection exacerbated the expression of autophagic proteins induced by diabetes; On the other hand, high-intensity interval training can as a preventive strategy, modulate diabetes-induced myocardial autophagy.

Abstract

Background: Diabetes mellitus is one of the most common endocrine diseases. Cardiovascular disease (CVD) is one of the leading causes of death in patients with type 2 diabetes. The aim of this study was to investigate the metabolic profile of plasma amino acids in diabetic patients with cardiovascular disease.
Methods: The present study is a descriptive-analytical cross-sectional study on 140 patients including 35 patients with type 2 diabetes and cardiovascular disease (CVD.DM), 35 patients with type 2 diabetes and non-cardiovascular disease (DM). 35 non-diabetic patients with cardiovascular disease (CVD.nDM) and 35 non-diabetic patients with non-cardiovascular disease (HS) were referred to Diabetes Clinic No. 1 of Tehran University of Medical Sciences.
Results: 76 (54.3%) were male and 64 (45.7%) were female. The highest concentrations of glutamine and isoleucine were observed in DM.CVD, asparagine, serine, arginine, threonine, alanine, tyrosine, valine in DM.nCVD and methionine in CVD.nDM. The lowest concentrations of tyrosine and tryptophan in DM.CVD has been detected , and  methionine has been detected in DM.nCVD. The amino acids alanine, glutamine, tyrosine, valine, methionine, leucine, lysine and arginine significantly increased the chances of developing DM.nCVD. For each increase in Z-score per plasma concentration of isoleucine, the chances of developing cardiovascular disease without diabetes were significantly increased.
Conclusion: The amino acids alanine, glutamine, tyrosine, valine, methionine, leucine, lysine and arginine are involved in predicting the risk of DM.nCVD and isoleucine and methionine are involved in predicting the risk of CVD.nDM.

Abstract

Background: The prevalence of type 2 diabetes is rapidly increasing in the world. As a result of this disease, long-term insulin resistance develops, as a result of which pancreatic beta cells are destroyed and disappear, as a result insulin is not released. Recently, a protein called lipasin, which is responsible for signaling the liver to beta cells, has been discovered, and previous reports have shown that lipasin/betatrophin increases pancreatic β cell proliferation. Therefore, the aim of this study was to investigate the effect of eight weeks of high intensity interval training (HIIT) and endurance training on lipasin gene expression in rats with type 2 diabetes.
Methods: The study was performed on 25 Wistar rats with a mean weight of 160±10 g and age of 8 weeks. After induction of diabetes, the rats were randomly divided into three groups of 6: control and endurance and HIIT. And exercise was performed for eight weeks (5 sessions per week). QRT-PCR technique was used to evaluate changes in hepatic lipasin gene expression.
Results: The present study showed that after eight weeks of endurance training and HIIT, the expression of lipasin gene in the liver of rats in the training group increased significantly compared to the control group (P = 0.037); Also, a significant negative correlation was observed between lipasin gene expression and insulin resistance index in the exercise group compared to the control group (r = -0.605, P = 0.037).
Conclusion: It seems that performing eight weeks of endurance training and HIIT, by increasing the expression of lipasin gene can increase beta cells in diabetic patients and may be an effective non-pharmacological intervention to reduce the symptoms of this disease.

Abstract

Background: Diabetes and its oxidative stress increase the effects of this disease on heart tissue. On the other hand, exercise improves the antioxidant status of heart tissue. The aim of this study was to investigate the effect of 8 weeks of increased endurance training on superoxide dismutase activity and malondialdehyde levels in the heart tissue of mice with type 2 diabetes.
Methods: In this experimental study, 24 male Wistar rats (256 ±11.8 g, 10 weeks old) were divided into 4 groups of 6. Exercise program for 8 weeks of increasing endurance training. 48 h after completion of the protocol, the activity of superoxide dismutase enzyme and malondialdehyde levels in rat heart tissue were measured. One-way analysis of variance was used for group comparisons and Pearson test was used to examine the relationship between indicators.
Results: There were significant difference between the four groups in superoxide dismutase (P= 0.001) and malondialdehyde (P= 0.001) indices. As a result of post-hoc test, there were significant increase in superoxide dismutase index in healthy exercise (P= 0.016) and control groups (P= 0.029) compared to diabetic control group and significant decrease in malondialdehyde index in control (P= 0.003), diabetic exercise (P= 0.050) and healthy exercise groups (P= 0.001) compared to diabetic control group. Significant correlation was observed between superoxide dismutase and malondialdehyde indices (r= 0.018, P= 0.274).
Conclusion: According to the results of this study, it seems that incremental endurance training reduces lipid peroxidation and improves antioxidant status and consequently reduces oxidative stress in cardiac tissue of diabetic rats.

Abstract

Background: One of the most important biological pathways involved in maintaining energy homeostasis is the AMPK PGC-1α pathway. Activation of this pathway through exercise can be important in regulating mitochondrial biogenesis processes and maintaining energy balance in diabetics. Therefore, the aim of this study was to investigate the effect of endurance exercise on the content of AMPK and PGC-1α proteins in the left ventricular heart tissue of male rats with type 2 diabetes.

Methods: In this experimental study, 12 two-month-old Sprague-Dawley rats with a mean weight of 270±20 g were selected. After diabetic induction with STZ and Nicotinamide, rats were randomly assigned to two groups, training diabetic and control diabetic (6 heads in group each). The training group performed 4 days a week for 8 weeks, including 30 minutes of endurance training with an intensity of about 50 to 70% of the maximum speed; While the control group did not have any training program. Also, rats did not receive any insulin treatment during the study period. The independent t-test was used in SPSS software version 21 to analyze the data.

Results: A significant increase was observed in the content of AMPK (P=0.002) and PGC-1α (P=0.0001) proteins in the endurance exercise group compared to control.
Conclusion: Based on the results of the present study, endurance exercise was able to significantly increase the content of AMPK and PGC-1α proteins. Therefore, it is possible that an increasing these proteins can lead to energy production and increase mitochondrial biogenesis.

Abstract

Background: Obesity and type 2 diabetes can impair the function of cells, including CREB and CRTC2 proteins, which are important for regulating adipose tissue metabolism. Therefore, the purpose of the present study was to investigate the effect of eight weeks of high intensity interval training (HIIT) on CREB and CRTC2 proteins levels in subcutaneous adipose tissue of obese rats with type 2 diabetes.

Methods: In this experimental study, 12 head two-month-old Sprague-Dawley rats with a mean weight of 300±20 g were selected. After diabetic induction with Streptozotocin and Nicotinamide, rats were randomly assigned to two groups, diabetic training (6 heads) and diabetic control (6 heads). The training groups performed the training program 4 days a week for 8 weeks, including 5 interval 4-minute with an intensity of 85 to 95% of the maximum speed, and 3-minute active rest periods with an intensity of 50 to 60% of the maximum speed; SPSS software version 23 and independent t-test were used to analyze the data.
Result: After eight weeks of HIIT training, no significant change in CREB protein level was observed in the training group compared to the control (P<0.22); However, a significant increase in CRTC2 protein level was observed in the training group compared to the control (P<0.005);
Conclusion: HIIT training did not result in a change in CREB protein level. But, it was able to increase the CRTC2 protein level, which could lead to the regulation of adipose tissue metabolism in diabetic subjects.
