Volume 3, Issue 2 (10-2015)
Abstract

Background and Objective: The industrial development along with the rising in human population has led to releasing considerable hazardous materials such as heavy metals into the environment. Environmental pollution by heavy metals can in turn threaten the human health. Therefore, the aim of this study was to assess the concentration levels of some heavy metals including; Cd, Pb, Cr and Cu, as well as to estimate the physico-chemical parameters of drinking water distribution network of Sanandaj city in 2014.

Methods: In order to accomplish the present descriptive study, 18 samples were collected from the water distribution network of Sanandaj during 2014. The level of heavy metals were assayed by using a graphite furnace atomic absorption (Phoenix 986). The standard approaches mentioned in the standard method book were used to measure the fluoride, nitrate and hardness of water. The Pearson Correlation test was used to estimate the association between parameters.

Results: The mean concentrations of Cd, Pb, Cr and Cu were found to be 0.0004, 0.011, 0.03, 0.3 mg/L respectively. Moreover, the mean levels of fluoride, nitrate, and total hardness were 0.11, 6.57, and 166 mg/L respectively. The level of Hazard Quotient in this study was lower than 1 (HQ < 1).

Conclusion: The concentration of all heavy metals in this study were lower than the national and international thresholds of drinking water. It is concluded that Sanandaj drinking water is safe to drink concerning health issues.  


Non-syndromic multiple supernumerary teeth: A case report
Masoud Esmaeili, Negin Khosravi, Ali Habibi Kia,
Volume 8, Issue 2 (7-2020)
Abstract 
Background: Supernumerary teeth are known as the teeth in excess of the normal dentition. Multiple supernumerary teeth are usually observed as having syndromes. Conversely, multiple supernumerary teeth without any associated systemic conditions or syndromes are not common. 
Case presentation: This article documents an unusual case report, a male patient with non-syndromic 10 supernumerary teeth in both jaws, an incidental finding during routine radiographic examination. 
Conclusion: CBCT is the best diagnostic imaging method currently available for determining the relationships of teeth and the surrounding structures in cases with multiple impacted teeth or severe overlapping of impacted teeth.

The Effect of Magnification for Detecting Low and High Internal Root Resorption in Single-Root Teeth in Cone-Beam Computed Tomography (an in Vitro Study)
Ali Habibi Kia, Arash Dabaghi, Pouya Nikdast,
Volume 9, Issue 4 (12-2021)
Abstract
Background and Objective: Early detection of Internal Root Resorption (IRR) is considered a challenging issue in endodontics. Processing filters are used to facilitate image interpretation either in diagnostic or treatment procedures. The aim of this study was to investigate the effect of magnification changes on the detection of IRR in Cone Beam Computed Tomography (CBCT) images.
Material and Methods: In this study, a total of 34 healthy single-canal & rooted teeth were split mesiodistally through their medial canal using an ultra-thin metal saw (1 mm). Then, absorption cavities were artificially created in both low and high degree absorption forms. CBCT images with three different magnification levels of 50, 100 and 150 were analyzed by one radiologist and one endodontist before and after artificial cavity creation. Gathered data were analyzed by MacNemar and Kappa tests using SPSS statistical software. Overall accuracy was calculated by the area under the curve (AUC).
Results: Calculated percentages of sensitivity, specificity and overall accuracy for the first (with high image magnification) and second (with low image magnification) observer were the same (100%, 88.24% and 94%, respectively) and there was no significance difference between low and high degree of resorption and also different magnifications with reality.
Conclusion: Depending on its method of application, all levels of magnification for CBCT images are suitable in diagnosis of IRR.

Abstract
Background: Performing exercise training with various protocols, especially aquatic exercises, can be effective against the harmful effects of Multiple Sclerosis. Therefore, the present study aimed to investigate the effect of six weeks of swimming training on the Caspase-1, TGF-β1, and IFN-γ protein content in the hippocampal tissue of rats with Multiple Sclerosis.
Methods: Twenty-one Wistar rats were divided into three equal groups: (1) Healthy control, (2) Multiple Sclerosis control, and (3) Multiple Sclerosis swimming. After two weeks of adaptation to the laboratory environment, the Multiple Sclerosis groups were induced by adding cuprizone to their diet. Six weeks of swimming training were then performed. Forty-eight hours after the last session, hippocampal tissue was isolated to examine Caspase-1, TGF-β1, and IFN-γ protein content. To analyze the data, one-way analysis of variance was used with a significance level of 0.05.
Results: Findings showed that the induction of Multiple Sclerosis in rats caused a significant increase in TGF-β1 and Caspase-1 protein content (P-Value=0.001) and a significant decrease in IFN-γ (P-Value =0.001). After six weeks of swimming, there was a significant decrease in Caspase-1 (P-Value =0.001) and a significant increase in IFN-γ (P-Value =0.001) protein content; however, there was no significant decrease in TGF-β1 protein content (P-Value =0.1).
Conclusion: Based on the findings of this study, it can be concluded that swimming, as a non-pharmacological intervention, has a protective effect on nerves by reducing factors related to inflammation and cell death, which may have beneficial effects on memory information processing in Multiple Sclerosis disease.

Abstract
Background: Research has shown that high-intensity interval training (HIIT) is a convenient and time-efficient approach that promotes oxidative capacity. Therefore, this study aimed to investigate the effect of HIIT on the gene expression of some inflammatory and anti-inflammatory markers of hippocampal tissue in aged male Wistar rats.
Methods: In this experimental study, 21 male Wistar rats were divided into three equal groups: 1- control (C), 2- elderly control (EC), and 3- elderly training (ET). After two weeks of adaptation to the laboratory environment, six weeks of HIIT were performed for the training group. Forty-eight hours after the last training session, hippocampal tissue was isolated to examine the mean levels of interleukin-10 (IL-10), IL-6, and IL-1β gene expression. One-way analysis of variance and Tukey's post-hoc test with a significance level of 0.05 were used to analyze the data.
Results: There was a significant increase in the expression of IL-6 and IL-1β, while a significant decrease in IL-10 expression (p=0.001) in the C group compared to the EC. After six weeks of HIIT, expression of IL-6 (p=0.001) and IL-1β (p=0.001) significantly decreased, whereas IL-10 expression significantly increased (p=0.001) in the ET group compared to the EC group.
Conclusion: It seems that HIIT activity has beneficial effects on preventing the process of neural degeneration. Moreover, it is promising as a non-pharmacological strategy for controlling complications resulting from the aging process due to its anti-inflammatory properties.
