BACKGROUND
Hemangioblastomas occur as sporadic or as von Hippel-Lindau syndrome (VHL) associated tumors. In both settings, activation of the VHL-HIF-1 (hypoxia induced factor) pathway is thought to be important in tumor biology.
METHODS
We performed immunohistochemical studies on 23
Tissue hypoxia results from the interaction of cellular respiration, vascular oxygen carrying capacity, and vessel distribution. We studied the relationship between tumor vasculature and regions of low pO(2) using quantitative analysis of binding of the 2-nitroimidazole EF5 given to patients
Bartonella species are highly fastidious, vector borne, zoonotic bacteria that cause persistent intraerythrocytic bacteremia and endotheliotropic infection in reservoir and incidental hosts. Based upon prior in vitro research, three Bartonella sp., B. bacilliformis, B. henselae, and B. quintana can
