s Previous studies indicated that intermittent hypoxia resulted in an enhancement of plasma testosterone, increased response of Leydig cells to human chorionic gonadotropin (hCG), and angiogenesis in rat testes. Hypoxia has been shown to stimulate the expression of vascular endothelial growth factor (VEGF), which is a major mediator for angiogenesis and vasculogenesis. During hypoxia, VEGF prom...
Inhibition of expression of cell adhesion molecules (CAM), including intercellular CAM-1 (ICAM-1), vascular CAM-1 (VCAM1), and E-selectin, has been shown to be important in controlling various inflammatory diseases. The cell adhesion proteins are induced by various inflammatory cytokines, such as tumor necrosis factor-a, interleukin-1, and bacterial lipopolysaccharide. The induction process pri...
What is the role of citizenship in a protest? How are civilian rights used as a source of power to craft socio-spatial strategies of dissent? I argue that the growing civilian consciousness of the “power to” (i.e. capacity to act) and of the border as public space is enhancing civil participation and new dissent strategies through which participants consciously and sophisticatedly use their cit...
In their article "Comparative Literature in Chinese" Xiaolu Wang and Yan Liu describe the development of comparative poetics in Chinese by sketching major publications and the general institutional situation of the discipline. Wang and Liu suggest that comparative work remains impulsive while at the same time dynamic. Like other fields in the humanities, the study of poetics — comparative or ot...
In their article "Perspectives on Video Games as Art" Jeroen Bourgonjon, Geert Vndermeersche, and Kris Rutten engage in discussing whether or not video games can be considered a form of art. Although this question has already been discussed elaborately, the debate is guided by many different and often conflicting positions. The aim of this article is to revisit this debate by mapping out a rang...
LIBRARIES ARE AN ESSENTIAL COMPONENT of a nation’s information infrastructure, yet often they are invisible to their users and other stakeholders. In the context of this special issue, the paper presents four challenges faced by libraries and proposes research designs to address each of them. The four challenges involve: 1.invisible infrastructure, 2. content and collections, 3. preservation an...
VEGF-A and VEGF receptors, Flt-1/FLT-1 (VEGFR-1) and Flk-1/KDR (VEGFR-2), are key regulators of tumor angiogenesis and tumor growth. The purpose of this study was to determine the anti-angiogenic and anti-tumor efficacy of vascular-targeting fusion toxin VEGF121/rGel in an orthotopic glioblastoma mouse model using non-invasive in vivo bioluminescence imaging (BLI), magnetic resonance imaging (M...
Extracellular vesicles (EVs) can modulate microenvironments by transferring biomolecules including RNAs and proteins derived from releasing cells to target cells. To understand the molecular mechanisms maintaining the neural stem cell (NSC) niche through EVs, a new transgenic (Tg) rat strain that can release human CD63-GFP expressed EVs from the NSCs was established. Human CD63-GFP expression w...
