این پژوهش با هدف "بررسی وضعیت موجود آموزش عالی مجازی در ایران و راههای توسعه و ارتقای آن " و با روش توصیفی-تحلیلی و پیمایشی صورت پذیرفته است. بررسی اسنادو مدارک موجود در زمینه آموزش مجازی نشان داد تعداد دانشجویان و مقاطع تحصیلی و رشته محل های دوره های الکترونیکی چندان مطلوب نبوده و از نظر کیفی نیز وضعیت شاخص خدمات آموزشی اساتید و وضعیت شبکه اینترنت در محیط آموزش مجازی نامطلوب است.
Roles of the heat shock transcription factors in regulation of the heat shock response and beyond.
The heat shock response, characterized by increased expression of heat shock proteins (Hsps) is induced by exposure of cells and tissues to extreme conditions that cause acute or chronic stress. Hsps function as molecular chaperones in regulating cellular homeostasis and promoting survival. If the stress is too severe, a signal that leads to programmed cell death, apoptosis, is activated, there...
متن کاملConservation of a stress response: human heat shock transcription factors functionally substitute for yeast HSF.
Heat shock factors (HSF) are important eukaryotic stress responsive transcription factors which are highly structurally conserved from yeast to mammals. HSFs bind as homotrimers to conserved promoter DNA recognition sites called HSEs. The baker's yeast Saccharomyces cerevisiae possesses a single essential HSF gene, while distinct HSF isoforms have been identified in humans. To ascertain the deg...
متن کاملRegulation of the heat shock response by heat shock transcription factors
The heat shock response is characterized by a rapid and robust increase in heat shock proteins upon exposure to protein-damaging stresses. This evolutionarily conserved cellular protection mechanism is primarily regulated at the level of transcription. In bacteria, heat shock-induced transcription is regulated by the activation of σ factor, whereas eukaryotes utilize heat shock transcription fa...
متن کاملThe human heat shock protein hsp70 interacts with HSF, the transcription factor that regulates heat shock gene expression.
Transcriptional regulation of the human hsp70 gene in response to heat shock and other forms of physiological stress occurs through the activation of heat shock transcription factor (HSF). Exposure of cells to a heat shock temperature of 42 degrees C results in transient activation of HSF; its DNA-binding activity increases rapidly, plateaus, and attenuates, during which the intracellular level...
