Long-term fluorescence of erythrosine in alive mammalian cells

the effects of keyword and context methods on pronunciation and receptive/ productive vocabulary of low-intermediate iranian efl learners: short-term and long-term memory in focus

از گذشته تا کنون، تحقیقات بسیاری صورت گرفته است که همگی به گونه ای بر مثمر ثمر بودن استفاده از استراتژی های یادگیری لغت در یک زبان بیگانه اذعان داشته اند. این تحقیق به بررسی تاثیر دو روش مختلف آموزش واژگان انگلیسی (کلیدی و بافتی) بر تلفظ و دانش لغوی فراگیران ایرانی زیر متوسط زبان انگلیسی و بر ماندگاری آن در حافظه می پردازد. به این منظور، تعداد شصت نفر از زبان آموزان ایرانی هشت تا چهارده ساله با...

Genetics of Somatic Mammalian Cells* Hi. Long-term Cultivation of Euploid Cells from Human

The animal cell lines most readily cultivated by current tissue culture techniques are usually aneuploid in chromosomal constitution and often have originated in malignant tissue (1). Most workers report that normal cells from adult individuals either fail to grow in vitro, or grow only for brief periods, usually a few weeks or months, after which proliferation ceases (2). Application of recent...

Isolation and long-term culture of neural stem cells from chondrostei fish Acipenser persicus

In the present study, an in vitro brain cell culture was developed from Persian sturgeon (Acipenser persicus). The tissues from anterior, middle and posterior regions of the brain were dissected, dispersed and cultivated separately in DMEM/F12 medium supplemented with 15% fetal bovine serum, antibiotic and antimycotic. The medium was changed every 3 days. The cells became confluent after about ...
