The small GTPase Rab27a, along with the isoforms of Rab3, is present on insulin secretory granules and has been implicated in regulation of Ca(2+)-triggered exocytosis. We have used membrane capacitance measurements to define the role of Rab27a in regulating the size and refilling of distinct pools of insulin granules by comparison of evoked secretory responses from Rab27a-null ashen and strain...
BACKGROUND A genomic biomarker identifying patients likely to benefit from drotrecogin alfa (activated) (DAA) may be clinically useful as a companion diagnostic. This trial was designed to validate biomarkers (improved response polymorphisms (IRPs)). Each IRP (A and B) contains two single nucleotide polymorphisms that were associated with a differential DAA treatment effect. METHODS DAA is ty...
The aim of the present study was (i) to investigate the effect of inner speech on cerebral hemodynamics and oxygenation, and (ii) to analyze if these changes could be the result of alternations of the arterial carbon dioxide pressure (PaCO2). To this end, in seven adult volunteers, we measured changes of cerebral absolute [O2Hb], [HHb], [tHb] concentrations and tissue oxygen saturation (StO2) (...
In present day power systems, Power Quality (PQ) issues are causing great concern owing to the increased use of electronic controlled drives and fluctuating other non-linear loads. This problem is further aggravated by a steady increase in integration renewable energy-based Distribution Generation (DG), employing converters distribution systems. Custom devices with suitable control strategies p...
در این مقاله، مسئلۀ برنامهریزی یکپارچۀ منابع (irp) با استفاده از نوعی مدل بهینهسازی با حداقل هزینه، مدلسازی شده است. در این مدل، تابع هدف مجموع هزینههای سرمایهگذاری، بهرهبرداری و تعمیرات و نگهداری منابع سمت تولید و همچنین هزینۀ اجرای برنامههای مدیریت بار است. قابلیت اطمینان سیستم، با استفاده از شاخص های مقدار انتظاری انرژی تأمین نشده (eens) و احتمال تأمین نشدن بار (lolp)، برآورد و تأمی...
in this paper an algorithm for computing the balaban and randic indices of any simple connected graph was introduced. also these indices were computed for ipr c80 fullerene isomers, zigzag nanotubes and graphene by gap program.
