Subarachnoid hemorrhage (SAH) serves as a good model for the study of heart-brain interactions because it is associated with both a high incidence of arrhythmia and a low prevalence of coronary heart disease. The pathophysiology of cardiac abnormalities in SAH is unsettled. Initial theories focused on sustained stimulation of cardiomyocytes at sympathetic nerve endings, but recent data suggest ...
متن کاملFound: The Elusive ANTAR Transcription Antiterminator
Regulated transcription termination provides an efficient and responsive means to control gene expression [1]. Intrinsic terminators, which consist of an RNA stem-loop followed by a poly-U tract, catalyze termination by disrupting the RNA polymerase elongation complex [2]. In antitermination, an antiterminator stem-loop is mutually exclusive with the terminator stem-loop [1,3]. In different con...
متن کاملElectroconvulsive Therapy Increases Plasma Levels of In t erleukin - 6 " ZIAD
There is now ample evidence of close interactions between the central nervous system and the immune system. Neurohormones and neurotransmitters play an important role in immunomodulation. Similarly, products of the immune system contribute to neuroendocrine secretion and may also possess specific behavioral properties. Animal studies have shown that stress can interfere with immune regulation a...
متن کاملThe Mechanism for RNA Recognition by ANTAR Regulators of Gene Expression
ANTAR proteins are widespread bacterial regulatory proteins that have RNA-binding output domains and utilize antitermination to control gene expression at the post-initiation level. An ANTAR protein, EutV, regulates the ethanolamine-utilization genes (eut) in Enterococcus faecalis. Using this system, we present genetic and biochemical evidence of a general mechanism of antitermination used by A...
متن کاملThe Constancy of Colored After-Images
We undertook psychophysical experiments to determine whether the color of the after-image produced by viewing a colored patch which is part of a complex multi-colored scene depends on the wavelength-energy composition of the light reflected from that patch. Our results show that it does not. The after-image, just like the color itself, depends on the ratio of light of different wavebands reflec...
