Most of the systematic studies used in the development of human embryo culture media have been done first on mouse embryos. The general use of NMRI outbred mice is a model for toxicology, teratology and pharmacology. NMRI mouse embryo exhibit the two-cell block in vitro. The objective of this study was to evaluate and compare the effects of four kinds of culture media on the development of zygo...
Purposes: Propranolol HCl is a beta blocker commonly used worldwide; however, it shows a low bioavailability due to its extensive first-pass metabolism. To solve this problem, a novel drug delivery system such as buccoadhesive system might be helpful. The aim of the present investigation is to prepare the buccoadhesive tablet of propranolol HCl using different mucoadhesive polymers. Method: Buc...

Introduction: Cutaneous Leishmaniasis (CL) is a parasitic disease caused by Leishmania species. Currently accessible treatments remain insufficient, and there is pressure to develop suitable and effectual options. In this study, we used different concentrations of podophyllin in vitro on leishmania parasites and then on leishmaniasis lesions in mice and compared their efficacy. Method: We used ...
the aim of this study was to investigate the in vitro developmental competence of isolated pre-antral follicles derived from vitrified ovaries in the presence of coenzyme q 10 (coq 10 ) . mice pre-antral follicles derived from fresh and vitrified-warmed ovarian tissues were in vitro cultured individually in α-mem medium supplemented with or without coq 10 , followed by adding human chorionic go...
به منظور بررسی میزان کاهش آفلاتوکسین b1 توسط نانوزئولیت (نانوذرات نقره + زئولیت)، نانوذرات نقره (نانوسید)، زئولیت طبیعی و دو افزودنی تجاری (میلبوند-tx و پلی سورب) آزمایشی در شرایط in vitro و in vivo طراحی شد. جهت تولید آفلاتوکسین b1 از یک ویال استاندارد aspergillus parasiticus ptcc-5286 (تهیه شده از گنجینه میکروبی سازمان پژوهش های علمی و صنعتی ایران) استفاده شد. تعیین میزان کاهش آفلاتوکسین در ش...
سیمان های گلاس آیونومر به دلیل چسبندگی مناسب به عاج و مینا و همچنین رهایش فلوراید بیش از 30 سال است که در دندان پزشکی استفاده می شوند. این سیمان در طی چند دقیقه گیرش می یابند و استحکام بالایی را بدون انقباض و بدون ایجاد دمای بالا ایجاد می کنند. درصورتیکه این سیمان ها خاصیت بیواکتیویته از خود نشان دهند، بهترین کاندید برای تثبیت ایمپلنت های ارتوپدی به استخوان مجاور می باشند. در این پژوهش پارامتر ...
fars province is one of the natural habitats of pyrus species in iran. harvesting of fruits, deforestation, expansion of agriculture and overgrazing in recent years has threatened the wild pear open forests and imposed detrimental effects on their natural regeneration, therefore, investigation on propagation of wild pear species for afforestation is needed. this research was carried out to deve...
the major purpose of this study was to develop the translation teacher competency test (ttct) and examine its construct and predictive validity. the present study was conducted in two phases: a qualitative phase as well as a quantitative phase. in the first phase of the study, the author attempted to find out the major areas of competency required for an academic translation teacher. the second...
two separate factorial experiments were conducted to study the effects of explant sources, plant growth regulators, sucrose concentrations, and light conditions on in vitro cormlet formation of freesia (freesia ×hybrida bailey 'argenta'). interestingly, it was observed that the pupae had lower contamination levels compared to mother corms. using 40% sodium hypochlorite solution for 40 min, cont...
