Despite the burgeoning literature on creative cities, seldom explored is the context of cities rich in cultural capital but more orthodox in their approach to preserving the auton omy of culture. This article discusses the status of artistic spaces occupying aban doned industrial premises (‘creative brownfields’) in historic cities that traditionally shape their policies around prestigious cul...
با توجه به بحران انرژی در عصر حاضر و هزینه های بالای انرژی و استفاده روز افزون از منابع روشنایی، محققان در تلاش برای جایگزینی ادوات جدید با بهره و طول عمر بالا هستند. همچنین محیط زیست بحران دیگری است که در این عصر جوامع انسانی با آن روبروست. تولید تجهیراتی که دارای مواد سمی و آلاینده و همچنین برای انسان مضر نباشد از اهداف دیگر محققان است. امروزه به دلیل ویژگی های led، این قطعه نیمه هادی به عنوا...
BACKGROUND After portal vein ligation of 1 side of the liver, the other side regenerates at a slow rate. This slow growth may be accelerated to rapid growth by adding a transection between the 2 sides, i.e., performing portal vein ligation and parenchymal transection. We found that in patients undergoing portal vein ligation and parenchymal transection, portal vein hyperflow in the regenerating...
Takehara N, Matsubara H. Cardiac regeneration therapy: connections to cardiac physiology. Am J Physiol Heart Circ Physiol 301: H2169–H2180, 2011. First published September 30, 2011; doi:10.1152/ajpheart.00768.2011.—Without heart transplantation, a large number of patients with failing hearts worldwide face poor outcomes. By means of cardiomyocyte regeneration, cardiac regeneration therapy is em...
The biostimulating effect of laser radiation has been observed in many areas of Medicine. However, there are still several questions to be answered, among them the importance of light coherence in the stimulatory process. In the present study, we used light-emitting diodes (LED) to promote the stimulation of liver regeneration after partial hepatectomy in rats. Fourteen male Wistar rats weighin...
Bioactive glasses were discovered in 1969 and provided for the first time an alternative to nearly inert implant materials. Bioglass formed a rapid, strong, and stable bond with host tissues. This article examines the frontiers of research crossed to achieve clinical use of bioactive glasses and glass-ceramics. In the 1980s, it was discovered that bioactive glasses could be used in particulate ...
Role of Cd34 Expression and Cellular Fusion in the Regeneration Capacity of Myogenicprogenitor Cells
INTRODUCTION: Characterization of myogenic progenitor cells has traditionally been performed using the well-defined myogenic regulatory factor family (MRF) of transcription factors. Observed differential expression patterns of these MRF proteins have led to proposed organizational models of hierarchy among myogenic progenitor cells. However, recent interest in the isolation of myogenic populati...
