Changes in the function of the adrenergic neurons of the heart may be important indicators of the adaptations of an animal to physiologic stress and disease. Rates of loss of norepinephrine (NE) from the heart were considered to be proportional to NE secretion and to adrenergic function. In rat hearts, yohimbine induced almost identical increases in rates of loss of 3H-NE and of 125I-metaiodobe...

The crystal of meta-dinitrobenzene, C6H 4(N 02)2> is orthorhombic pyram idal. The dimensions of the un it cell, which contains 4 molecules, are a = 13-3A, 6 = 14*1 A, c = 3-80A and the space group is Pbn. The m ethod of double Fourier series has been applied, and a projection of the electron density on the ab plane has been made. The plane of the benzene ring of the molecule is inclined a t an ...

As we have reported recently, the human neuroblastoma cell line SK-N-SH is able to take up and store m-iodobenzylguanidine (mIBG). This is in contrast to several other neuroblastoma cell lines, among which are SK-N-LO cells. Both cell lines were used in cell killing experiments with unlabeled and radioactive-labeled mIBG. Using 1-200 microCi m-[131I]IBG (1 h incubation time), only SK-N-SH cells...

Be it snow, volcanic ash or strikes, crisis events impose high costs on the air transport system and society. Airlines have progressively learned to mitigate the irregular operations arising from such events through procedures such as Collaborative Decision Making (CDM) for tra c ow and airport departure management; however the passenger's door-to-door journey during di cult times often remains...

There has been a steep increase in the number of meta-analyses of genome-wide association (GWA) studies aimed at identifying genetic variants with increasingly smaller effects, but pressure to publish findings of new genetic associations has limited the time available for careful consideration of all of their methodological aspects. The authors surveyed the literature (2007-2010) to provide emp...

The molecular structures of the three closo-carbaboranes, ortho-, meta- and para-C2B10H12, were experimentally determined using gas-phase electron diffraction (GED). All unique bond distances for ortho and meta carbaboranes were determined experimentally for the first time. For ortho-carbaborane (RG= 0.046), a model with C2v symmetry refined to give bond distances of 1.624(8) A for C-C, 1.093(8...

Studies of human performance in complex tasks using video games are an attractive prospect, but many existing games lack a comprehensive way to modify the game and track performance beyond basic levels of analysis. Meta-T provides experimenters a tool to study behavior in a dynamic task environment with time-stressed decision-making and strong perceptual-motor elements, offering a host of exper...
