Bilateral and symmetric globus-pallidus hyperintensities are observed on T1-weighted MRI in most of the patients with chronic liver failure, due to manganese accumulation. We report a 53-year-old man, with rapid onset parkinsonism-dementia complex associated with accumulation of manganese in the brain, secondary to liver failure. A brain MRI was performed and a high signal on T1-weighted images...

The anatomical organization of the basal forebrain cholinergic system with emphasis on the basal magnocellular nucleus, was studied by means of the choline acetyltransferase immunohistochemistry. The basal forebrain cholinergic system extends from the medial septum to the caudal part of the globus pallidus, and is organized as a continuous valley of cholinergic neurons. The arrangement of choli...

Stage I. Stereotaxic radiological localization of the globus pallidus. The position of the globus pallidus is calculated from radiographs taken after lumbar air encephalography. For this procedure the patient is placed in the sitting position. A graduated metal frame is secured to the head by three drills penetrating the outer plate of the skull. Air is injected into the ventricular system by l...

As computers become better connected across the globe, opportunities to create new programs utilizing geographically distant resources increase. New applications not possible without this computational grid include distributed supercomputing and intelligent sensing applications. However, di culties implementing this new class of applications exist: the computers on a grid are unreliably connect...

Pallidotomy was performed in a parkinsonian patient with off-period foot dystonia. Dystonia appeared at the beginning of surgery and disappeared after the first microelectrode penetration of the globus pallidus, perhaps a micropallidotomy effect. Neuronal recording during dystonia revealed that the mean firing rates were low in both the internal and external segments of the globus pallidus, and...

Grids are collections of interconnected resources harnessed to satisfy various needs of users. Legion and Globus are pioneering grid technologies. Several of the aims and goals of both projects are similar, yet their underlying architectures and philosophies differ substantially. The scope of both projects is the creation of worldwide grids; in that respect, they subsume several distributed sys...

Annotation of organism-specific metabolic networks is one of the main challenges of systems biology. Importantly, owing to inherent uncertainty of computational annotations, predictions of biochemical function need to be treated probabilistically. We present a global probabilistic approach to annotate genome-scale metabolic networks that integrates sequence homology and context-based correlatio...

The cortex and basal ganglia are the major structures of the adult brain derived from the embryonic telencephalon. Two morphologically distinct regions of the basal ganglia are evident within the mature ventral telencephalon, the globus pallidus medially, and the striatum, which is positioned between the globus pallidus and the cortex. Deletion of the Sonic Hedgehog gene in mice indicates that ...

Of 60 patients with acute carbon monoxide (CO) intoxication caused by accidental or intentional inhalation of natural gas, smoke inhalation, or inhalation of automobile exhaust, 23 had characteristic computed tomographic findings. The most common finding, seen in 21 patients, was symmetric and diffuse low density in the cerebral white matter, which was more advanced in the centrum semiovale and...

Globus Nexus is a professionally hosted Platform-as-a-Service that provides identity, profile and group management functionality for the research community. Many collaborative e-Science applications need to manage large numbers of user identities, profiles, and groups. However, developing and maintaining such capabilities is often challenging given the complexity of modern security protocols an...
