Direct Inputs to off Α and G9 Ganglion Cells From Aii Amacrine Cells In Rabbit Retina
In the mammalian retina, AII amacrine cells are essential in the rod pathway for dark-adapted vision. But they also have a “day job”, to provide inhibitory inputs to certain OFF ganglion cells in photopic conditions. This is known as crossover inhibition. Physiological evidence from several …

Angiotensin II modulates glutamate-induced depolarizations and synaptic transmission in rat locus coeruleus neurons in vitro.
… or neuromodulatory role for angiotensin II (AII) in the central nervous system (CNS). The objectives of this research are to study the actions of AII on spontaneous activity and on Glu-induced responses in rat locus coerulus neurons. The action of AII appears to be selective since it had no …

Studies of the renin angiotensin system in the human vasculature
… thesis concentrates on the local generation of AII. Preliminary experiments using wire myography were performed in human resistance arteries from normal subjects, obtained by subcutaneous gluteal at biopsy. In these vessels, AI stimulated a contractile repose that was dependent on activation of …

A Characterization of the Effect of Apolipoprotein AII on the Structure and Function of Apolipoprotein AI in Reconstituted High Density Lipoproteins
… which contains apolipoprotein (apo) AI and apoAII, and a fraction which contains apoAI but not apoAII. The effect of apoAII on the structure and function of apoAI in reconstituted HDL was investigated. ApoAII was labeled with the fluorescent probe dansyl chloride (DNS) and added to rHDL …

The Study of Nitric Oxide Synthase Expression, Function, and Regulation in the Renal Vasculature During Postnatal Renal Development
… vasoactive factors, such as angiotensin II (AII) has not been examined. In the immature kidney, nitric oxide synthase (NOS) isoforms, specifically eNOS and nNOS, are developmentally regulated, but their specific role and regulation are unknown.</p> <p>The enhanced vasodilatory role of NO in …

Signaling Mechanisms That Control Gap Junctional Coupling Between Retinal Neurons
… of retinal neurons, including the Cx36-coupled AII amacrine cell in the primary rod circuit, is a hallmark of retinal luminance adaptation. However, very little is known about the mechanisms regulating dynamic modulation of Cx36-mediated coupling. The primary goal of this work was to understand …

Zur Wirkung von Additiven auf die Hydratationsreaktion von Anhydrit II
Anhydrit II (AII) wird industriell hauptsächlich als Bindemittel bei der Fußbodenestrich-Herstellung eingesetzt. Zur Beschleunigung der Abbindereaktion und der daraus resultierenden schnelleren Verfestigung des Fußbodens wird Kaliumsulfat als Additiv verwendet. Im Rahmen dieser Arbeit wurden …

Expression of microbial rhodopsins in retinal neurons with subcellular targeting motifs: for the study of the structure/function of aii amacrine cells and for vision restoration
… the dissertation reports in the axonless spiking AII amacrine cell of the mammalian retina a dendritic process sharing organizational and functional similarities with the axon initial segment, the typical site of action potential initiation. This process was revealed through viral-mediated …
