Study of blood fat levels in patients with Arcus Juvenilis
Get PDFBackground: Corneal arcus is a situation in which a white to yellow ring appears in the stromal tissue of the cornea and been separated from limbus by a transparent margin of 0.3 to 1 millimeters. Accumulated materialof the corneal arcus are composed mainly from low density lipoproteins, phospholoipids and triglyceride. In some studies, a corneal arcus under 50 year old is associated with high blood fats which can also increase the risk of cardiovascular complications in the patients.
Aim:To determine the amount of blood fats in patients with arcus juvenilis.
Methods and meterials: The current study was a cross-sectional one. All of the patients who were under 50 year-old, referring to the Ardabil ophthalmology clinic of Emam Reza (pbuh) hospital and diagnosed with arcus juvenilis were enrolled in the study using case-series method. Needed information including age, gender, blood pressure, body mass index, history of smoking and alcohol consumption, type of received therapy to decrease the blood fat, xanthelesma, history of cardiovascular and cerebrovascular events were gathered using history taking and medical examination using a researcher pre-made checklist.
Results: Fifty nine cases were enrolled in the study. Among all 36 (61%) were male. 74.6% of the patients were either obese or overweight. Mean level of Cholesterol, LDL, HDL and Triglyceride were 199.81±30.46, 114.56±24.56, 46.3±9.61 and 175.9±125.
Conclusion: Finally it can be concluded from the current study that prevalence of obesity, overweight and abnormal levels laboratory indices associated with lipids are significant in patients suffering from arcus juvenilis

The Effects of Implementing an Occupational Health and Safety Management System on Functional Indices: A Five-year Study in Casting Industry
No full textIntroduction: Assessment of the performance of management systems is one of the main concerns of managers. The measure of success of an occupational health and safety management system is the ex-tent of its effectiveness. The effects of implementing an OHSMS on health and safety perfor-mance indices in a casting site located in Iran between 2015 and 2019 were examined. Methods: A retrospective descriptive-analytical study was conducted over five years on 21 depart-ments of a casting site. All the functional indices one year before the implementation of OHSAS 18001:2007 in 2015 until a year after the implementation (2019) were monitored and the data were analyzed using SPSS (v.19). Results: There was a significant decrease in occupational accidents after the implementation of OHSAS 18001:2007. Mechanical and ergonomic factors demonstrated significant improvements. There were improvements in the indices of opening health files for the personnel, personal protective equipment, education, instructions, legal requirements, commitment, and leadership. There was no significant change in chemical and physical factors. Conclusion: Implementation of the occupational health and safety manage-ment system was effective in the indices that needed managerial control with no or low expenses. However, it was not effective in indices in engineering and technical areas that needed more expenses
Evaluation of Patients Viewpoints Referred to Ardabil Dental Educational clinic on Dental Students' Professional Ethics in Clinical field in 2019
Get PDFIntroduction: In the medical community, the issue of ethics has a special place due to the importance of this profession and dentistry, like other branches of medical sciences, needs such attention. The aim of this study was to investigate the views of patients referred to Ardabil Dental Clinic regarding the observance of professional ethics of dental students in the clinical field in 2019.
Materials & Methods: The present study was a Descriptive Analytical study, which has been done in the Faculty of Dentistry of Ardabil University of Medical Sciences on 340 patients referred to the faculty selected randomly by telephone by stratified random sampling. A researcher-made questionnaire consisting of 23 closed-ended questions was used to collect information. After collecting the data in order to analyze them, the correct choice of questions (the option that was in accordance with ADA ethics) was given a score of one and the incorrect options of zero. Then, it was analyzed using SPSS statistical software version 22, independent t-test, analysis of variance, Mann-Whitney and Kruskal-Wallis at an error level of 5%.
Results: The results showed that in 88% of the students had observed professional ethics in the clinical field, but had difficulty in informing about the cost of dentistry in 42.94% and the speed and readiness of the work in 61.18%. Also, no significant difference was observed in the level of observance of professional ethics of dental students in the clinical field based on gender and age (P> 0.05); However, there was a significant difference in the level of observance of professional ethics of dental students in the clinical field based on marital status, semester and education of patients (P <0.05); And observance of professional ethics of dental students in the clinical field, the lowest value was observed in the orthodontic department and the highest value was observed in the preoperative ward (P <0.05).
Conclusion: The results of the study revealed that dental students in Ardabil have a high skill in dealing with their patients in terms of observing the professional ethics in the clinical field
An Experimental Study on Elastic Properties of Four Different Brands of Elastomeric Orthodontic Chains
Get PDFBackground: Elastomeric chains are used to close space in orthodontics.
AIM: An Experimental Study on Elastic Properties of Four Different Brands of Elastomeric Orthodontic Chains
Materiaals and Methods: In this study the elastic properties of elastomeric chains from four different companies were investigated. In this experimental study, 6-loop transparent elastomeric chains from four American orthodontics companies, SIA, G&H and Protect were evaluated in two groups. In the first group, the elongation test of each specimen was determined by applying 150 and 300 grams of force. The force dissipation test was also performed to determine 100% of the initial force per stretch in distilled water for 1 hour, 24 hours, 1 week, 2 weeks and 3 weeks after immersion in the distilled water.
Results: The results showed that the SIA brand tensile test had less tensile strength of 150 grams and 300 grams than the other three samples. The two brands of G&H and American orthodontics have roughly the same stretch.
Conclusion: Power dissipation test showed that the duration of retention in distilled water has a direct effect on power dissipation, and both Protect and G&H brands have more degradation in distilled water than the other two brands, and this value has increased over time to 21 day
SNP-SNP interactions of oncogenic long non-coding RNAs HOTAIR and HOTTIP on gastric cancer susceptibility
Get PDFGenetic variants within oncogenic long non‑coding RNAs HOTAIR and HOTTIP may affect their gene expression levels, thereby modifying genetic susceptibility to gastric cancer (GC). In a hospital‑based study in Ardabil—a very high‑risk area in North‑West Iran, 600 blood samples from 300 GC patients and 300 healthy controls were recruited for genotyping. Seven HOTAIR (i.e., rs17720428, rs7958904, rs1899663, and rs4759314) and HOTTIP (i.e., rs3807598, rs17501292, and rs1859168) ‘tag’ single nucleotide polymorphisms (SNPs) were genotyped by the Infinium HTS platform. The rs17720428, rs7958904, and rs1899663 tagSNPs significantly increased GC risk under dominant models by 1.5‑, 1.57‑, and 1.5‑fold, respectively. The G‑C‑T‑A haplotype of HOTAIR tagSNPs increased the risk of GC by 1.31‑fold. No significant association was found between HOTTIP SNPs and the risk of GC. HOTAIR and HOTTIP variants were also not associated with any clinicopathologic characteristics. The SNP ‑SNP interaction of HOTAIR rs17720428/rs7958904 with HOTTIP rs1859168 was associated with an increased risk of GC (rs17720428 TG‑rs1859168 CC, OR = 1.76; rs7958904 GC‑rs1859168 CC, OR = 1.85; rs7958904 CC‑rs1859168 CC, OR = 1.86). Interestingly, the SNP‑SNP interaction of HOTAIR rs1899663 with HOTTIP rs1859168 strongly increased the risk of GC (rs1899663 GT‑rs1859168 CC, OR = 4.3; rs1899663 TT‑rs1859168 CC, OR = 9.37; rs1899663 TT‑rs1859168 CA, OR = 6.59). We showed that the HOTAIR rs17720428, rs7958904, and rs1899663 tagSNPs and their interactions with the HOTTIP rs1859168 polymorphism significantly increased the risk of GC. Specifically, novel SNP‑SNP interactions between HOTAIR and HOTTIP tagSNPs have a larger impact than individual SNP effects on GC risk, thereby providing us with valuable information to reveal potential biological mechanisms for developing GC
