Two transcription pause elements underlie a σ70-dependent pause cycle.
The movement of RNA polymerase (RNAP) during transcription elongation is modulated by DNA-encoded elements that cause the elongation complex to pause. One of the best-characterized pause sequences is a binding site for the σ(70) initiation factor that induces pausing at a site near lambdoid phage late-gene promoters. An essential component of this σ(70)-dependent pause is the elemental pause si...
متن کاملEffective Aid for Hitting the Bull’s Eye; Comment on “It’s About the Idea Hitting the Bull’s Eye”: How Aid Effectiveness Can Catalyse the Scale-up of Health Innovations”
This article studies how six key aid effectiveness principles for “Hitting the bull’s eye” can bring about the scale up of maternal and newborn health (MNH) interventions. These key principles are based on accepted international agreements such as the Paris Declaration on Aid Effectiveness. The results indicate that the six principles should be a guide for recipient countries to take ownership ...

قاعده مقتضی و مانع در متون فقهی کم و بیش مستند احکام قرار گرفته و مورد مناقشه فقهاء و اصولیین می باشد و مشهور معتقند مقتضی و مانع، قاعده نیست بلکه یکی از مسائل ذیل استصحاب است لذا نگارنده بر آن شد تا پیرامون این قاعده پژوهش جامعی انجام دهد. به عقیده ما مقتضی دارای حیثیت مستقلی است و هر گاه می گوییم مقتضی احراز شد یعنی با ماهیت مستقل خودش محرز گشته و قطعا اقتضاء خود را خواهد داشت مانند نکاح که ...
15 صفحه اولPause-and-stop: the effects of osmotic stress on cell proliferation during early leaf development in Arabidopsis and a role for ethylene signaling in cell cycle arrest.
Despite its relevance for agricultural production, environmental stress-induced growth inhibition, which is responsible for significant yield reductions, is only poorly understood. Here, we investigated the molecular mechanisms underlying cell cycle inhibition in young proliferating leaves of the model plant Arabidopsis thaliana when subjected to mild osmotic stress. A detailed cellular analysi...
متن کاملEffect of miRNA-1266-5p repression on the increasing cell survival and alterations of the cell cycle in AGS cell line
Background: Gastric cancer is among the most common malignancies in certain parts of the world, such as northwest Iran. miRNAs are small and single-stranded noncoding RNAs with about 19-23 nucleotides. Several studies have shown that miRNAs play important roles in gastric tumorigenesis. The aim of this study was to determine the effect of miRNA-1266-5p repression on the cell survival and altera...
