The Effect of Concurrent Endurance and Resistance Exercise on Plasma Levels of Vascular Endothelial Growth Factor and Endostatin in Inactive Women

Introduction: The present study aims to investigate the effect of one concurrent endurance and resistance exercise training session on plasma levels of vascular endothelial growth factor (VEGF) and endostatin in inactive women. Methods: In this quasi-experimental study, 12 inactive female university students were divided into control (average age=20.0 ±1.78 years, height = 161.3 ±50 cm, weight = 58.83±5.71 kg, BMI = 22.38±3.23 kg/m2) and exercise (average age =19.5±1.04 years, height = 163.1±3.79 cm, weight = 58.67±7.69 kg, BMI =22.35±2.22 kg/m2) groups. The endurance exercise was performed on a treadmill with 65% of MHR for 16 minutes. The resistance exercises of four movements including leg press, chest compression, armpit and leg stretch were performed at 50% 1RM in two sets with 10 repetitions and 1-2 minutes’ rest intervals between sets. Data were analyzed using dependent t-test and independent t-test to determine differences within the group and between-group at pthe control group (p= 0.168). Conclusion: According to the findings, it seems that one session of concurrent endurance and resistance exercise has a positive influence on VEGF and probably it can help to improve the condition of angiogenesis

The Effect of A Single Bout of Aerobic Exercise on Ergometer on Inflammatory and Hormonal Markers in Active Girls

Introduction: Exercise is an important strategy for reducing the risk of chronic disease, and recent research has focused on its role in the improvement of the inflammatory profile. The present study aimed to investigate the effect of a single bout of aerobic exercise on ergometer on inflammatory and hormonal markers in active girls. Methods: 16 physical education students with average age of 20.25 ±0.9 years, maximal oxygen uptake of 42.14±9.8 ml/kg/m and body mass index of 22.11±2.66 kg/m2 were randomly divided into experimental and control groups. The experimental group pedaled on ergometer with intensity of 75 % VO2max for 60 minutes and the control group had no activity during the test. Blood samples for measuring the levels of IL-10, TNF-α, CRP, cortisol, epinephrine were taken before, immediately and 2 hours after termination of the exercise. The data were analyzed by paired t-test, repeated measure ANOVA and Bonferroni post hoc at P 0.05). The mean values of CRP (P=0.002) and cortisol (P=0.001) were higher in the experimental group than the control group. In addition, the mean values of epinephrine in the control group were higher than the experimental group (P=0.009), while no significant difference was observed between the two experimental and control groups in the concentration of IL-10 (P> 0.05). Conclusion: Based on the findings of study, it seems that an exercise session on an ergometer does not affect hormonal and inflammatory factors in active subjects

Assessment of the pollution potential of groundwater in Khaledabad Badrood aquifer using DRASTIC model

Surface water resources are limited in many regions in Iran, so groundwater resources are considered the most suitable resources for supplying water. The excessive use of chemical pests and fertilizers has resulted in groundwater pollution. Therefore, it is necessary to determine the vulnerable areas to preserve these vital resources. In this study, the DRASTIC model was used to analyze the vulnerability of groundwater in Khaled-Abad- Bardood plain. Seven factors including the nutrition of pure water, groundwater depth, unsaturated area, soil texture, Hydraulic conductivity, aquifer media, and topography were used in the model. After the preparation of 7 layers, appropriate weight was assigned to these factors. Finally, by mapping these layers and applying their weight to them in ArcGIS 10.5, the vulnerability maps of the groundwater were generated. To validate the model, sampling and measuring the amount of nitrate for 13 wells located in the Khaled-Abad-Bardood plain were conducted. The results indicated that 22% of the plain was vulnerable based on the DRASTIC model, which was located in the vicinity of Bardood city and its eastern areas. The results also showed that the correlation of the DRASTIC vulnerability map with the measured nitrate was found to be 74 %

Structural changes of cardiac tissue in response to boldenone supplementation with or without alcoholic extract of jujuba fruit during resistance training in male Wistar rats

Background: Abuse of anabolic androgenic steroids has been linked to a variety of different cardiovascular side effects. The use of medicinal herbs has been shown to reduce disease and cardiovascular disorders. This study aimed at examining the structural changes of the cardiac tissue in response to boldenone supplementation along with the alcoholic extract of jujuba during resistance training in male Wistar rats. Materials and Methods: In this experimental study, 30 male Wistar rats aged 8-12 weeks (weight 202±9.34 g) were randomly divided into five groups: control, boldenone, extract of iujuba+boldenone, boldenone+resistance training and boldenone+resistance training+extract of jujuba. The resistance training program included climbing the ladder for 8 weeks, 3 days a week, 1 session training in a day and each session consisted of the 3 sets and 5 repetitions. Injection was conducted in depth in the hamstring once a week, on an appointed day. After anesthesia, autopsy was performed and the cardiac tissue was isolated. Results: The results showed that boldenone caused tissue damage, hyperemia, abnormal cytoplasm and unclear and dispersed nuclei. In the boldenone+resistance training group, the heart tissue had high levels of hyperemia and the muscle cells were a little abnormal. In the boldenone+jujube group, appearance of the tissue was normal and a restorative effect was evident in the tissue. Conclusion: It seems that boldenone can cause structural damage to the heart tissue and the resistance training along with the jujube extract can reduce some of the cardiovascular disorders (necrosis and inflammation) caused by the use of anabolic steroids

Background: Diabetes is a chronic disease which can lead to increased levels of leptin and lipid profile. The aim of this study was to examine the effect of resistance training and genistein on leptin and lipid profile of streptozotocin-induced diabetic rats. Materials and Methods: In this experimental study, 56 diabetic rats were divided into 7 groups of 8 rats including control, resistance training, 30 mg/kg genistein consumption, 10 mg/kg genistein consumption, resistance training and 30 mg/kg genistein consumption, resistance training and 10 mg/kg genistein consumption, and sham. The training groups performed a resistance training program for 8 weeks and 5 sessions per week. Results: Resistance training had a significant effect on reduction of leptin, triglyceride, cholesterol and very-low-density lipoprotein (VLDL) (P≤0.05). Genistein consumption had a significant effect on reduction of leptin and increased high-density lipoprotein (HDL) levels (P≤0.05) and had no effect on reduction of triglyceride, cholesterol, LDL and very low-density lipoprotein (VLDL) (P≥0.05). Resistance training along with genistein consumption had an interactional effect on reduction of leptin, triglyceride, cholesterol, LDL, and VLDL and increased HDL (P≤0.05). Also, 10 mg/kg and 30 mg/kg genistein consumption had similar effects on reduction of leptin and increased HDL levels in diabetic rats (P≥0.05). Conclusion: Resistance training along with genistein consumption has interactional effects on leptin and lipid reduction in streptozotocin-induced diabetic rats

The effect of high-intensity interval training on IL-22 and STAT3 gene expression of liver tissue in steatosis animal model

Inflammation is a major component of almost all acute and chronic liver disorders, including non-alcoholic fatty liver disease. This study aimed to investigate the effect of high-intensity interval training on IL-22 and STAT3 gene expression of liver tissue in steatosis animal model. In this experimental study, 32 rats (weighing 200-250 gr) were selected and randomly divided into 4 groups including healthy control, fatty liver, HIIT and fatty liver + HIIT group. Rats were infected with fatty liver by oral tetracycline at a dose of 140 mg/kg (soluble in 2 ml of water) for 7 days. The HIIT exercise program performed on treadmill five sessions per week for 5 weeks. The IL-22 and STAT3 gene expressions in the liver tissue of samples were measured by Real Time PCR. Data were analyzed by One-way ANOVA and Tukey post hoc tests at significance level P <0.05. The results showed that the gene expression of IL-22 in liver tissue in HIIT group and fatty liver + HIIT was significantly lower than that in the fatty liver group (P = 0.001). Also, the gene expression of STAT3 in liver tissue in HIIT group and fatty liver + HIIT was significantly higher than that in the fatty liver group (P = 0.001). According to the results, the HIIT training program seems to help improve the liver steatosis

DETERMINING THE SENSITIVE CONSERVATIVE SITE IN KOLAH GHAZI NATIONAL PARK, IRAN, IN ORDER TO MANAGEMENT WILDLIFE BY USING GIS SOFTWARE

One of the basic keys in the conservation and management principle of protected region especially national parks is identifying the ecological resources of the region. Undoubtedly in each ecosystem, there are regions which are more significant in terms of riches species and the presence of valuable and important species (conservative sensitive site) has favorable conditions than the other regions, these regions are significant in terms of conservation strategies and ecotourism management. Therefore, identifying this sensitive conservative site could have new evaluation in the management of conservative regions. The aim of this research was presenting solutions for biodiversity strategic managements, by considering sensitive conservative site in Kolah Ghazi National Park. During one-year regular monitoring of the Kolah Ghazi National Park, in Isfahan, diversity and abundance of fauna and flora of the region in terms of species richness with their exact geographical position were recorded by direct observation. Available documentary data and regional profiles were used to complete data. For evaluating data random pallet m2400 methods and also the distance from the nearest neighbor were used. By overlaying ecological maps by using GIS software, a conservation map was prepared in which three conservation levels (high, medium and low protection) were considered for the region. The highest density of species is on the spot which is marked on the map as high conservation. In the following, suitable management strategy for each season, according to three categories of conservation of the lo, medium and high will be provided

Evaluation of Repellency and Lethal Effects of Ultrasonic Waves on the Blat-tella germanica (Blattodea: Blattellidae)

Background: The German cockroach, Blattella germanica (Insecta: Blattodea, Blattellidae), which occurs widely in human buildings, is a small cockroach species. Cockroach control chemical pesticides are toxic to the environment, and it is sometimes impossible to prevent them. Controlling Blattella germanica through ultrasonic waves can be efficient and less dangerous for the environment. Methods: In this study, the repellency and lethal effect of ultrasonic waves on male and female German cockroaches was tested in a twin glass cubic chamber at laboratory condition. The wave frequencies tested ranged from 20 to 100kHz with 5kHz steps. A signal generator generated these frequencies, and the piezoelectric transmitter of these ultrasonic waves was positioned in the chamber's center on the upper side. Results: Fisher's test showed that there was the greatest repellency effect in both male and female at frequencies of 35 and 40kHz. According to the results of the regression test, the most lethal effect is at the frequencies of 40 and 75kHz. Conclusion: The operating ultrasonic frequencies investigated in this study can be used to repel and kill German cock­roaches as pests endangering human health and environment

Sampling and Analysis of Tars by Means of Photo Ionization Detection and Solid Phase Micro Extraction

Gasification of biomass will likely play an important role in the production of energy and chemicals in a future sustainable society. However, during gasification impurities, such as tars, will be formed. Tars may cause fouling and blockages of equipment downstream the gasifier. It is therefore important to minimize the formation of tars, alternatively to remove the formed tars. These processes need to be monitored, which makes it necessary to develop tar analysis methods suitable for this task. This work describes the development of two tar analysis methods, an on-line method based on a photoionization detector (PID) and an off-line method based on solid phase microextraction (SPME). Both methods were successfully validated against the established solid phase adsorption (SPA) method. The method based on PID was shown to have a very fast response time. Furthermore, the PID method is selective towards tar, but only limited information will be obtained regarding the composition of the tar compounds. The PID method is suitable for applications where it is important to detect fast changes of the tar concentration, i.e. process monitoring. The SPME method was shown to be a very sensitive method for qualitative and quantitative tar analysis. The sampling temperature was shown to be crucial for obtaining analysis results with the wanted detection limit. The SPME method is suitable for applications where extremely low detection and quantification limits are needed, i.e. for syngas production.  QC 20131009</p
