Niemann-Pick A disease (NPA) is a fatal lysosomal storage disorder caused by a deficiency in acid sphingomyelinase (ASM) activity. The lack of functional ASM results in cellular accumulation of sphingomyelin and cholesterol within distended lysosomes throughout the brain. In this study, we investigated the potential of AAV-mediated expression of ASM to(More)
Previous studies have shown that the bradykinin agonist, RMP-7, can safely permeabilize the blood brain barrier (BBB) by activation of constitutive B2 receptors on endothelial cells. The paper describes a series of studies using quantitative autoradiography and intracarotid infusions of RMP-7 to further elucidate the effect on BBB permeability. Because(More)
Niemann-Pick disease is caused by a genetic deficiency in acid sphingomyelinase (ASM) leading to the intracellular accumulation of sphingomyelin and cholesterol in lysosomes. In the present study, we evaluated the effects of direct intracerebral transplantation of neural progenitor cells (NPCs) on the brain storage pathology in the ASM knock-out (ASMKO)(More)
The effect and mechanism of the blood-brain barrier-permeabilizing agent, RMP-7, was investigated in a series of studies employing a rat RG2 glioma model. Changes in uptake of carboplatin into brain tumor and various nontumor brain tissue regions was determined using a sophisticated image analysis system. This system permitted quantitative autoradiography(More)
1. Adult coho salmon Oncorhynchus kisutch return each autumn to freshwater spawning habitats throughout western North America. The migration coincides with increasing seasonal rainfall, which in turn increases storm water runoff , particularly in urban watersheds with extensive impervious land cover. Previous field assessments in urban stream networks have(More)
An In Vivo model is presented to determine the effects of alpha methyl-para-tyrosine methyl ester (MPT), fusaric acid (FA), and haloperidol on nomifensine-induced seizures. All three drugs were active with haloperidol having the greatest effect on delay of onset to convulsion. The results suggest that both dopamine and norepinephrine are involved in(More)
