In vivo noninvasive visualization of retinal perfusion dysfunction in murine cerebral malaria by camera-phone laser speckle imaging.

Cerebral malaria (CM) is a severe complication of Plasmodium falciparum infection associated with impaired cerebral blood flow. Visualization of the eye vasculature, which is embryologically derived from that of the brain, is used clinically to diagnose the syndrome. Here, we introduce camera-phone laser speckle imaging as a new tool for in vivo, noncontact two-dimensional mapping of blood flow dynamics in the experimental cerebral malaria (ECM) murine model of Plasmodium berghei ANKA.

Safety of direct cardiac administration of AdVEGF-All6A+, a replication-deficient adenovirus vector cDNA/genomic hybrid expressing all three major isoforms of human vascular endothelial growth factor, to the ischemic myocardium of rats.

Abstract Coronary artery disease (CAD), a leading cause of mortality, is a chronic disease in which blood flow to the myocardium is obstructed, leading to ischemia. Although coronary artery stenting and surgical bypass are successful with localized coronary lesions, patients with diffuse CAD have only pharmacologic options. In a mouse ischemic hind-limb model, AdVEGF-All6A+, an Ad5 vector expressing the cDNA/genomic hybrid of the vascular endothelial growth factor (VEGF) gene (expressing isoforms, 121, 165, and 189) mediated recovery of blood flow at a dose of two logs less than that required with a single isoform.
