Background and aim: Pemphigus vulgaris (PV) is an autoimmune disorder that can clinically manifest as oral mucosal ulcers. Several researchers believe that the level of female sex hormones such as estrogen and progesterone could be effective in the pathogenesis and growth of lesions such as desquamative gingivitis. Studies related to oral ulcers have revealed contradictory results regarding the...
Cumulative absolute velocity (CAV), Arias intensity (AI), and characteristic intensity (CI) are measurable characteristics to show collapse potential of structures, evaluation of earth movement magnitude, and detection of structural failure in an earthquake. In this paper, parameters which describe three characteristics of ground motion have been investigated by using wavelet transforms (WT). I...
In this research, gas tungsten arc welding of dissimilar joint between 4130 low alloy steel and AISI 201 austenitic stainless steel was investigated. Four filler metals i. e. ERNiCr-3, ER 309L, ER 308L and ER 80SB2 were used. After welding, microstructural features of various areas and also fracture surfaces were examined using optical microscopy and scanning electron microscopy. Tensile test w...
Background and Aim: Breast carcinoma is a pervasive malignancy in the world, and in our country-Iran-as well. Extensive studies have been done on its diagnostic and therapeutic procedures and factors affecting its prognosis. The present study aimed at determining proliferative rate of cells, the condition of steroid hormone receptors, correlation of these with each other and with other factors ...
مقدمه:مطالعات نشان داده اند تابش لیزر می تواند منجر به استحکام باند قویتر سیستم ادهزیو شود. لذا هدف از این مطالعه به دست آوردن یک پروتکل مناسب جهت کاربرد لیزرهای er:yagو nd:yag به منظور بهبود استحکام باند در طی کاربرد یک نوع ادهزیو نسل 6 دو مرحله ای بود. مواد و روش ها:در این مطالعه تجربی، تعداد 70 دندان سالم کشیده شده انتخاب و به 7 گروه مساوی تقسیم گردید. گروه کنترل(c) مطابق دستورالعمل کارخ...
introduction: pyogenic granuloma (pg) is a common tumor-like growth of the oral cavity, considered to be of non-neoplastic nature, often caused by constant low-grade trauma as well as poor oral hygiene and maybe due to hormonal disturbances. surgical excision, and removal of underlying cause in some cases, is the preferred method of treatment as it is only a benign lesion. in order to remove th...
