The study of hdac4 gene expression pattern after endurance exercises in animal model

Fathi M (2017)
Background and aims: The most of endurance activity induced changes occur by epigenetic processes which Histone deacetylase 4 transcription factor plays a central role in that. Therefore, the aim of this study was to investigate the effect of endurance activity on slow and fast twitch muscles hdac4 gene expression. Methods: The subjects of this experimental study were 14 rats (231±24 gr) that housed under standard conditions. After familiarization with training protocol, there were randoml...

Investigating students’ attitude towards the importance of factors included in the teaching evaluation forms of School of Public Health of Shahid Sadoughi University of Medical Sciences in 2010-2011

M. H Dehghani Tafti; M. H Baghianimoghadam; M. H Ehrampoush; N Ardian; N Seyghal (2012)
Introduction: students’ attitudes about teaching methodology have been widely recognised as a valid tool of evaluating teaching activities of faculty members. This study aims to determine the importance of the factors included in the teaching evaluation, from the students’ point of view. Methods: This is a cross-sectional study. Using a random cluster sampling, 332 students of the school of public health of Shahid Sadoughi University were selected .To collect data, a questionnaire containing ...

Comparison of the anesthetic efficacy of articaine infiltration versus lidocaine inferior alveolar nerve block in pulp therapy of lower primary molars

Maryam Sharifi; Ayda Karimaghaee; Foad Iranmanesh; Mahmood Sheikhfathalahi (2017)
Introduction: Pain control is essential to the behavioral management of children in pediatric dentistry. Effective anesthesia plays a key role in this regard, especially in pulp therapy. In order to achieve successful anesthesia, the type of analgesics and injection techniques should be considered. The present study aimed to compare the anesthetic efficacy of articaine infiltration and lidocaine inferior alveolar nerve block in the pulp therapy of lower primary molars. Materials and Methods: ...

Simulation Furrow Irrigation by Winsrfr4.1 in order to Determine the Optimum Length of Furrow

Mona Golabi; M. R. Sikakinezhad; A. Shir Afrous; M. Albaji (2017)
Introduction: Surface irrigation methods are the most common methods for irrigation of agricultural land. These methods are superior to sprinkler, drip and underground irrigation, because they have lower costs of funding and implementation, is inexpensive, needed maintenance of equipment is simple and does not require skilled labor. New requirements for the use of municipal water, energy, industrial, and military intends to further improve the performance of surface irrigation systems. In oth...

The Influence of Ammonium Sulphate added to the Spray Solution of Calcium Carbonate-Containing Glyphosate and Nicosulfuron on Barnyardgrass and Velvetleaf Control

kamal hajmohamadnia; Mohammad Hassan Rashed Mohassel; Mehdi Nassiri Mahallati; Eskankar Zand (2016)
Introduction: There are many reasons for no effectiveness of herbicides on weeds, including the incorrect herbicide, the insufficient use of herbicide, the unprincipled sprayer, spraying at the wrong time especially adverse weather conditions, and a factor that often overlooked is the "water quality in herbicide spray tank". Most of the herbicides are mixed with water and applied as a spray. Obviously water quality is an extremely important issue. Water quality factors in this regard that eff...

Effect of One Carpet Weaving Workstation on Upper Trapezius Fatigue

Neda Mahdavi; Majid Motamedzade; Abbas Moghim Beygi; Ali Ashraf Jamshidi; Rashid Heydari Moghaddam (2016)
Introduction: This study aimed to investigate the effect of carpet weaving at a proposed workstation on Upper Trapezius (UTr) fatigue during a task cycle. Fatigue in the shoulder is one of the most important precursors for upper limb musculoskeletal disorders. One of the most prevalent musculoskeletal disorders between carpet weavers is disorder of the shoulder region. Methods: This cross-sectional study, included eight females and three males. During an 80-minute cycle of carpet weaving,...

Modeling of Electrochemical Treatment of Phenol and Prediction of Specific Energy Consumption

Najmeh Khabbazi; Soosan Rowshanzamir (2013)
Phenol belongs to the recalcitrant pollutants to conventional physical chemical and biological treatments. These compounds are released in the surface water by a considerable number of industries, constituting an environmental hazard.  On the other hand, the advanced oxidation processes (AOPs) have been defined as effective processes for treatment of wastewater containing toxic and persistent organic pollutants. In this work, a mathematical model is developed to quantify the variation of chem...

پیش‌بینی مقاومت فشاری سنگ دارای همسانگردی عرضی‌ با استفاده از روش المان مجزا

فاطمه عزیزیان; عبدالهادی قزوینیان; محمود بهنیا (2014)
ناهمسانگردی یکی از مهم‌ترین ویژگی‌های سنگ­های رسوبی و دگرگونی است که نقش تعیین‌کننده‌ای در تعیین رفتار این نوع سنگ‌ها تحت بارهای وارده بر آن‌ها ایفا می‌کند. به همین منظور مطالعات آزمایشگاهی گسترده‌ای باهدف بررسی تأثیر ناهمسانگردی بر رفتار مکانیکی و مقاومت نهایی چنین سنگ‌هایی انجام شده است. با توجه به قابلیت‌های موجود در روش‌های عددی با مبنای المان مجزا در مدلسازی فرآیند شکست نمونه‌های دارای ناهمسانگردی و همچنین توانایی این روش‌ها در رفتار نگاری شکست سنگ‌ها تحت فشارهای تک‌محوره و سه‌محوره، در ...
