هدف از انجام این مطالعه مقایسه دو روش mpn-pcr و mpn-culture در شمارش باکتری لیستریا مونوسیتوژنز تلقیح شده به شیر استریل می باشد. برای انجام این کار تعدادcell/ml 103 از باکتری لیستریا مونوسیتوژنز و نیز باکتری های زمینه ای مختلف به شیر استریل تلقیح شدند. پس از آماده سازی رقت های متوالی، از هر رقت در سه لوله حاوی محیط غنی کننده لیستریا تلقیح شد. پس از 48 ساعت گرمخانه گذاری، برای آزمایش mpn-cultu...
Background and purpose: Ëmbryo co-culture systems with somatic cells have been a subject of extensive study as valuable tools to promote embryo in vitro development. The aim of this study was to evaluate, the Ëffects of a special kind of co-culture system in which somatic cells were cultured as polarized monolayer on mouse embryo development. Materials and methods : Human oviduct was obtai...
Background: This study was conducted to evaluate fibroblast co-culture and Activin A on in vitro maturation and fertilization of mouse preantral follicles. Methods: The ovaries from 12-14-day-old mice were dissected, and 120-150 μm preantral follicles were cultured individually in α-MEM as based medium for 12 days. A total number of 456 follicles were cultured in four conditions: (i) base mediu...
In vitro culture of human ovarian tissue the following cryopreservation is proposed for follicular development. There are no techniques that guarantee successful maturation of the follicles within the excised tissue. The viability of cultured human ovarian tissue improved by adding some growth factors to the culture media. The efficiency of vitrification as the cryopreservation method for human...
The primary therapeutic goal for the oncology patient is survival. Recent advances in diagnoses and treatment of neoplasia have resulted in an ever-increasing number of patients being cured and resuming a normal life. However, recognized side effects of treatments used to eradicate malignancies are temporary or permanent sterility. The cryopreservation of ovarian tissue harvested before cancer ...
the present study aimed at investigating the possible impact ofzone of proximal development (zpd) on the learners’ performance. forty-sixiranian university students participated in this study by taking two types of readingcomprehension tests (i.e., the main idea and wh-question type). the researchersused the winstep program to analyze the data and estimate the learners’ raschmeasure in pre, pos...
learning a second or foreign language requires the manipulation of four main skills, namely, listening, reading, speaking, and writing which lead to effective communication. it is obvious that vocabulary is an indispensible part of any communication, so without a vocabulary, no meaningful communication can take place and meaningful communication relies heavily on vocabulary. one fundamental fac...
Though Muslims have been living in Nepal from the 15th century, they have started practicingtheir religious activities freely only after enactment of new civil code in 1963. This paper aims to explore the potentials and problems on the existing mosques, perception of the religious structures by Muslim community and analysing of existing legal and institutional framework before drawing a conclus...
Background This study was designed to develop a new co-culture system, assess the effect of luteinizing hormone (LH) using sequential media to promote development and increase the quality of 2-cell murine embryos through the 8-16 cell stage to morula and blastocyst stages. MaterialsAndMethods Monolayers for co-culture were prepared from ovine oviduct epithelial cells (OOEC) in DMEM/F12 medium a...
