this study is due to investigate the histological and histochemical properties of the tongue of the embryo and one day old ostrich chickens. twelve eggs in various embryonic stages (22, 26, 30 and 36 embryonic days) and three one day chicks were used. the specimens from whole of tongue were collected and after preparing tissue were stained by histological staining methods include h & e,masson t...
the main purpose of this research was to:1.develop a coking model for thermal cracking of naphtha.2.study coke inhibition methods using different coke inhibitors.developing a coking model in naphtha cracking reactors requires a suitable model of the thermal cracking reactor based on a reliable kinetic model.to obtain reliable results all these models shall be solved simultaneously.for this pu...
Background and purpose: Chronic stress is known as a state that disrupts the body homeostasis that could cause significant behavioral and hormonal changes. In this study the changes in estrogen, progesterone, cortisol, and testosterone hormonal level and histological changes in uterus tissue induced by immobilization stress were studied. Also, the protective effect of royal jelly was investigat...
Background: Fixation of biopsy specimens is a critical step before processing and staining them for histological tissue examination. Formalin considered the gold standard fixative solution its attributes. However, it has concerning side effects, such as carcinogenic potential irritational properties. Owing to various harmful safer natural substitute should be explored. In this study, we compare...
Background: Tissue engineering is a developing multidisciplinary and interdisciplinary field involving the use of bioartificial implants for tissue remodeling with the target for repair and enhancing tissue or organ function. Acellular nerve has been used in experimental models as a peripheral nerve substitute. The purpose of the present study was to evaluate the mechanical and histological cha...
EXTRACELLULAR toxoplasma, although present in abundance in smears from animals infected experimentally, can only occasionally be found in sections from suspected toxoplasma lesions. In the eye, Wilder (1952a, b) has described organisms morphologically indistinguishable from toxoplasma in cases of granulomatous uveitis, but even in these sections the organisms were not numerous and were found on...
This review aimed to highlight the historical perspectives focused on histological stains and their application in teaching research. While early histologists used indigenous substances like alizarin, carmine, saffron stain tissues, modern utilize techniques that study cellular organelles within tissues. Despite advent of new staining techniques, modification old ones, decrease use natural dyes...
abstract nowadays, industries cannot play a crucial role in national and international competitions. the tourism industry is no exception. tourism industry development as the most important economic sector and income generation is one of the key challenges of economic development in the world. therefore, countries were successful that take advantage of the capabilities of tourism sector using ...
Objective(s): Menopause and diabetes obviously increase the risk of cardiovascular disease in women. The aims of the present study were to evaluate the effects of ovariectomy in type 2 diabetes on the histology and expression of miRNA-29, miRNA-133, IGF-1 and Bcl-2 genes and Bcl-2 protein and caspase 3 activity in the hearts of female rats. Materials and Methods: Forty Female Wistar rats were ...
