Introduction: The role of brain tissues oxidative damage in learning and memory impairments has been well documented. It is also well known that thyroid hormones have a critical role for the brain functions. The purpose of this study was to investigate the role of brain tissues oxidative damage as a possible mechanism of deleterious effects of propylthiouracil (PTU) - induced hypothyroidism on ...
objective: dna vaccines have been widely used to develop immunity against various pathogens including parasites and viruses. the potential of dna vaccine to induce an effective immune response is related to the expression levels of the encoded protein in eukaryotic cells. therefore, optimization of plasmid dna delivery system is a major concern in protein expression in order to make an efficien...
[Purpose] This study was conducted to examine physical status and life satisfaction of workers in Korea. [Subjects] In total, 25,455 workers from eight geographical areas were evaluated from 2007 to 2008. [Methods] Physical status of the subjects was measured based on cardiopulmonary endurance, muscular strength, muscular endurance, flexibility, and explosive muscular strength, and a life satis...
Bicarbonates and carbonates are the main factors of alkalinity in irrigation water. In order to determine suitable growth medium for gerbera (Gerbera jamesonii L. cv. Dafne) under alkalinity stress condition, a factorial experiment with completely randomized design with 4 replications was carried out. The experiment consisted of 7 levels of substrate (100% perlite, 100% cocopeat, 75% perlite+ 2...
Background & Aim: One of the common reasons for selecting C-section by mothers is the fear of labor pain. Hence, many attempts have been made to reduce C-section cases and increase painless delivery. Therefore, this study aimed to compare the efficacy of anesthesia with fentanyl injection and anesthesia with water injection on pain intensity, labor duration and satisfaction with labor in women ...
Background & aim: Women's choice on the type of delivery mode is an important event in every pregnant women’s lifetime. Proper education is one of the most important factors that can help women to choose the delivery type. In this regard, one of the educational methods is peer education. Therefore, this study aimed to determine the effect of peer education on the choic...
in reality, most structures involved in geotechnical engineering are three dimensional in nature, and although in many, plane strain or axisymmetric approximations are reasonable, there are some, for which 3-d treatment is required. the quantity of data, and the size of the various vectors and matrices involved in such analysis, increase dramatically. this has sever implications for computer r...
nowadays, air pollution is a global problem that has had significant growth by technology development, population growth andindustrial development. industrial development brought natural resources deterioration, more manufacturing products, and more environmental pollutants. if pollutant won’t be controlled, human-being and wildlife will face the critical risks. significant release and critical...
چکیده به منظور بررسی اثر تنوع گیاهی و نوع منبع تغذیه ای بر تنوع و تراکم علفهای هرز و حشرات، کارایی مصرف نهاده ها ( نور، آب، عناصر غذایی) و عملکرد و خصوصیات کیفی چند گونه زراعی، آزمایشی به صورت کرتهای خردشده بر پایه طرح بلوکهای کامل تصادفی با سه تکرار در دو سال زراعی 1385-1384 و 1386-1385 در مزرعه تحقیقاتی دانشکده کشاورزی دانشگاه فردوسی مشهد به اجرا درآمد. تیمارهای مورد بررسی دو منبع کود دامی و...
dendrimer synthesis strategies now provide virtual control of macromolecular nanostructures as a function of size and surface/interior functionality. these strategies involve the covalent assembly of hierarchical components reactive monomers , branch cells or dendron’s around atomic or molecular cores according to divergent/convergent dendrite branching principles.combinon of two or more dendri...
