Abstract Background & aim: Chronic otitis media surgery is the most common procedure in the field of otology in developing countries. Subtotal and total tympanic membrane perforation with inadequate anterior remnant is associated with higher rate of graft failure. This study aimed to evaluate the anatomical and functional outcomes of a modified underlay myringoplasty technique. Methods: In the present prospective clinical study, 45 patients with subtotal or total tympanic membrane perforation and inadequate anterior remnant underwent tympanoplasty (+/- mastoidectomy). Anterior tip of the temporalis fascia was secured in a mucosal pocket on the lateral wall of Eustachian tube orifice. Data on graft take rate, preoperative and postoperative hearing status and intraoperative findings were analyzed. The anatomical and functional findings of this procedure were analyzed by paired t-test. Results: A graft success rate of 91.1%, without lateralization, blunting, atelectasia or epithelial pearls was achieved in this study. About 24 % of patients had an air bone gap within 25db before intervention, which increased to 71% postoperatively.(P<0.001). Conclusion: It seems that the current technique could be a convenient and suitable method for cases with subtotal or total tympanic membrane perforation and inadequate anterior remnant.

Background and aim: Multiple sclerosis is a chronic and debilitating nervous system, leading to demyelination of the central nervous system (brain and spinal cord). Regular exercise and general physical activity is important to maintain health and prevent disease, already well known. Therefore the aim of this study was to evaluate the effect of 12 weeks of combined exercises (strength training, Strengthening Exercises, cardio respiratory endurance, a variety of static and dynamic balance exercises, exercises of the trunk (pilates training) and walking on the treadmill training with body weight support) on interferon gamma and Expanded Disability Status Scale women with multiple sclerosis.

Methods: In the present experimental rsearch, female patients who were admitted to the MS Society of Shahrekord, Iran, were divided into three groups based on physical disability scores. In the first group (physical disability scale less than 4.5), 44 people were randomly selected to one experimental group (22 patients) and control group (n = 22). In the second group (scale physical disability between 5 and 5.6), 26 patients were enrolled and randomly assigned to an experimental group (n = 13) and control group (n = 13). The third (Physical Disability Scale-up to 6.5), 26 patients were enrolled and randomly assigned to an experimental group (n = 13) and control group (n = 13). A total of 96 patients were participated in this study. Experimental groups of first, second and third were done its own intervention separately. While the control group received stretching exercises, workout schedule for the experimental group was of 12 weeks, three sessions of lasted one hour. Anthropometric factors and interferon-gamma were measured before and after training with the appropriate tools. Serum levels of INF-γ was determind using a commercial ELISA kit and EDSS scores were measured using the measure of disability in patients with MS. Data analysis was performed using descriptive statistics and ANOVA and paired t-test and dependent.

Results: The results showed that no significant differences were seen in the INF-γ subjects with low disability before and after exercise in the intervention group (p=1.017), whereas, there was no significant difference in the control group (p=0.229). In comparison, no significant difference was observed between intervention and control groups in terms of INF-γ (09/0 = p). The results indicated that significant differences INF-γ subjects with low disability before and after exercise was observed in the intervention group (p=0.309

Conclusion: Although combinated exercise training did not change on serum levels of IFN, but it casued asignificant changes in EDSS of the patients with M.S at different levels

Regarding these results, it can be suggested that rehabilitation specialists use of these exercises as a complementary treatment along with drug therapy for MS patients.

Abstract
 
Background & aim: Exposure to electromagnetic waves can lead to oxidative stress. On the other hand, the antioxidant system function of the body increases with regular exercise and reduces oxidative stress. The aim of this study was to investigate the effect of eight weeks aerobic training on oxidative stress markers in rats exposed to electromagnetic microwave radiation emitted from the Wi-Fi routers.
 
Methods: In this experimental study, 26 male Wistar rats (8 weeks old) with a weight range of 200±20 g were randomly divided into four groups including: control, radiation, exercise, and radiation + training. The main training program consisted of 8 weeks (one session a day and five days a week) running on a treadmill for animals at 40 to 60% max speed, and the protocol included one hour of exposure to a 45.2 GHz rays of Wi-Fi modem for 8 weeks. Before and 48 hours after the main interventions, blood samples were taken from all groups. Plasma superoxide dismutase (SOD) and glutathione peroxidase (GPX) levels were measured by ELISA and validated by MDA and MDA kits with TBA method. Data was analyzed using one way ANOVA, Tukey and T-test.
 
Results: The results of one-way ANOVA showed that there was a significant difference among the different groups in the study. Eight weeks of exposure to Wi-Fi radiation caused a decrease in plasma levels of SOD and GPx and an increase in MDA. On the other hand, eight weeks of aerobic exercise increased plasma levels SOD and GPx, and reduced MDA. Tukey's test showed that there was a significant difference between SOD and GPx in all groups, except for those with radiation + (p = 0.099 and p = 0.073). In MDA, the difference was significant among all groups, except for the aerobic group + aerobic training group with aerobic training and control groups (p = 0.331 and p = 0.717). The results of t-test showed a significant difference between pre-test and post-test of all variables in the research.
 
Conclusion: It seems that regular aerobic exercise exercises can have beneficial effects on the antioxidant system and modulate the oxidative stress indices induced by the Wi-Fi radiation.

Abstract

 

Background & aim: Lipid metabolism disorder plays an important role in insulin resistance in skeletal muscle and lipid drop proteins such as perlipine 2 (PLIN2) are effective in regulating intracellular fat metabolism. One of the suggested pathways for the effects of endurance activity in metabolic diseases is the effect of physical activity on intramuscular. Therefore, the purpose of this study was compare the intensity of aerobic exercise intensity (low intensity and high intensity) on expression of PLIN2 skeletal muscle, serum glucose and insulin levels in streptozotocin-diabetic rats.

 

Methods: In this experimental study, 24 male Wistar rats were randomly divided into three groups of 8, including two intervention groups (low intensity endurance training group and high intensity continuous exercise group) and one control group. After induction of diabetic rats by injection streptozotocin (55 mg / kg body weight), Intraperitoneally, endurance training was applied for eight weeks, three sessions per week in diabetic rats. Exercise intensity in the low-intensity group was equal to 5-8 m / min (equivalent to 50-60% Vo2max), the intensity of training in a high intensity training group was equivalent to a speed of 22-25 m / min (equivalent to 80% Vo2max) and the control group did not receive intervene in this time. Relative protein expression of PLIN2 was performed using western blot technique. Data were analyzed by one-way ANOVA and Tukey's post hoc test.

 

Results: The results of the intergroup comparison revealed a significant difference among three groups in the PLIN2 variables (p = 0.037). The results of post hoc test showed a significant increase in PLIN2 in high intensity training diabetic group compared to the control group (p = 0.033) However, there was no significant difference in PLIN2 level in the low exercise group compared to the control group (p = 0.18). Also, there was no significant difference between the low intensity and high intensity training groups (p = 0.66). Serum glucose and insulin levels were significantly different between diabetic control groups and low intensity and high intensity training (p = 0.001). This difference was between the high intensity training group with low intensity group (p = 0.04, p = 0.01), diabetes control (p = 0.001, p = 0/000), respectively.

 

Conclusion: Regarding the results of the study, modulation effects of high intensity endurance exercises on increasing the expression of PLIN2 in diabetic specimens were noted.

Background & Aim:Fat-Specific Protein 27 (Protein Specialty Protein) is one of the proteins that play a role in the regulation and metabolism of lipid droplets. The aim of this study was to evaluate the effect of endurance training on expression of specific lipid profile (FSP27) and insulin resistance in STZ-diabetic rats.

Methods: In this experimental study, 40 male Wistar rats were divided into five groups (diabetic group), low intensity endurance training (DLE), diabetic group, moderate intensity exercise (DME), diabetic group, and endurance training with intensity High (DHE), control group of diabetic (DC) and healthy control (HC). After diabetic administration, streptozotocin was injected with endurance training with low, moderate and high intensity for eight weeks, three sessions per week and each session for 30 minutes. Serum glucose levels were measured by glucometer, insulin with mouse specific ELISA kit, relative expression of FSP27 protein with Western Blot method and insulin resistance index. One-way analysis of variance and Tukey and James Howell post hoc tests were used to determine the difference between groups.

Results: The results showed that endurance training with three severity (low, moderate and high) had a significant effect on serum glucose, insulin and insulin resistance values ​​(p = 0.001). Reductions in serum salivary and glucose levels were significant in high intensity exercise groups and moderate intensity exercises versus diabetic control and low intensity exercise (p≤0.05). Insulin resistance values ​​were significantly higher in moderate and high intensity training groups compared to low exercise group, diabetic control group and healthy control group (p≤0.05). The expression of FSP27 protein in endurance training groups with three intensities with diabetic control and healthy control was not significantly different. However, the results showed that the content of FSP27 in the training groups increased with intensity of exercise compared to the diabetic control group (the value of p was exactly noche, not approximation)

Conclusion: Although, none of the endurance training interventions produced a significant difference in FSP27. Considering the tendency to increase FSP27 with increasing endurance training, it seems that endurance training with an appropriate intensity can be achieved by increasing FSP27 and subsequent reduction of the acids Free fat on the one hand and increased glucose uptake, on the other hand, increase insulin sensitivity and improve insulin resistance in diabetic rats.

Background & aim: Numerous studies have investigated the effect of exercise on diabetes-related factors. Aerobic exercise is a central component in the management and treatment of type 2 diabetes. The aim of the present study was to determine the effect of endurance training with different intensities on HBA1C in patients with type 2 diabetes.
 
Methods: This research is a systematic review and meta-analysis conducted in 2019.For the present study, databases from ScienceDirect, PubMed, Scopus, the science of the Web, SID, Magiran, and Google Scholar from years 2001 to 2019 were searched with keywords After initial screening, the full text of the articles was evaluated and the articles that met the inclusion criteria were analyzed. In total, 21articles were reviewed, of which 11coincided the criteria for systematic review and meta-analysis.  Moreover, 381 diabetic patients divided into two groups of 169 and 237, respectively, in the experimental group (99 females, 134 males) and the control group (57 females, 81 males). The mean age of the subjects in the present study was 52.62 years. Intervention effects were evaluated as mean difference (MD) with a random effects model. Data were analyzed using effect size, bias and heterogeneity tests using STATA software.
 
Results: The results of the meta-analysis indicated that both moderate and moderate aerobic exercise decreased HBAIC percentage. Endurance training in general reduced HBAIC levels significantly.  In the subgroup analysis, endurance training was moderate (p = 0.001, SE= 0.27,              V =0.07, CI =-1.51 -0.44 Z = -3.58) and high intensity (p= 0.001, SE= 0.22, V = 0.05, CI = -1.33 -0.46 Z = -4.05)
 
Conclusion: Different intensities of endurance training have a significant effect on HBA1C levels in type 2 diabetic patients. Our study showed that there is no significant difference between moderate and high intensity aerobic exercise in the rate of improvement of HBA1C levels, which, of course, is felt to investigate the difference between intensities to more research and higher quality.
