It has been suggested that some cortically blind patients can process the emotional valence of visual stimuli via a fast, subcortical pathway from the superior colliculus (SC) that reaches the amygdala via the pulvinar. We provide in vivo evidence for connectivity between the SC and the amygdala via the pulvinar in both humans and rhesus macaques. Probabilistic diffusion tensor imaging tractogr...

Diffusion MRI tractography is often used to estimate structural connections between brain areas and there is a fast-growing interest in quantifying these connections based on their position, shape, size and length. However, a portion of the connections reconstructed with tractography is biased by their position, shape, size and length. Thus, connections reconstructed are not equally distributed...

We compared growth of the recently discovered respiratory pathogen Chlamydia pneumoniae in McCoy, HeLa 229, BHK-21, and HL cells. When cells were not pretreated with DEAE-dextran, HL cells had significantly higher mean numbers of inclusion-forming units (IFUs) on initial inoculation than the other cell lines. When cells were pretreated with DEAE-dextran, HeLa 229 and HL cells had equivalent mea...

Wilson, Dwight E. (Rensselaer Polytechnic Institute, Troy, N.Y.). Fractionation of Newcastle disease virus by chromatography on diethylaminoethyl cellulose. J. Bacteriol. 84:295-301. 1962.-The L. Kansas and NK strains of Newcastle disease virus were chromatographed on diethylaminoethyl (DEAE) cellulose ion-exchange columns. L. Kansas virus eluted from DEAE columns showed one peak of hemagglutin...

Several reports have appeared that suggest that 24,25-dihydroxycholecalciferol has a possible biological role in bone formation. We have utilized competition studies, saturation analysis, sucrose-density-gradient sedimentation and DEAE-cellulose chromatography to demonstrate that long bones of vitamin D-depleted newborn rats contain cytoplasmic and possibly nuclear receptors that bind 24,25-dih...

Three serologically distinct antigens were identified in homogenates of Saint Louis encephalitis (SLE) virus-infected cells after Brij-58 solubilization and diethylaminoethyl (DEAE)-cellulose chromatography. These antigens were designated as antigen I, II, and III. Immunodiffusion analyses showed that all antigen peaks which eluted from the DEAE-cellulose column contained the intracellular majo...

For heterogeneous reservoirs, fast, stable and accurate methods are hard to obtain. Large changes in the velocity field leads to severe time-step restrictions in explicit schemes or expensive time steps in implicit schemes. In the absence of gravity, the exact velocity field will be loop-free in the sense that there are no closed integral curves. A sequential splitting strategy with streamline ...

PURPOSE Three-dimensional (3D) magnetic resonance phase contrast imaging (PC-MRI) allows non-invasive diagnosis of pulmonary hypertension (PH) and estimation of elevated mean pulmonary arterial pressure (mPAP) based on vortical motion of blood in the main pulmonary artery. The purpose of the present study was to compare the presence and duration of PH-associated vortices derived from different ...
