Many brain regions and circuits have been implicated in the neuropathology of schizophrenia. Drs. Bogerts and Jones have reviewed the evidence that links the disorder to temporal limbic structures and to frontal-thalamic circuits, respectively. Each article is an important update on what we know about the relevance of these brain regions to schizophrenia. In addition, each article, in summarizi...

MEDICINE & HEALTH/RHODE ISLAND The natural history of conversion disorders in general is interesting. The vast majority resolve without treatment in the first few weeks, while those that persist for several months generally persist forever. These are often disabling, and no treatment is known to be effective. The patients generally do poorly. The neurologist dismisses them with, “no neurologica...

Radionuclide shuntography is a safe and simple method to determine shunt patency and analyze changes in CSF (Cerebro-Spinal-Fluid) flow. We present a case of complicated CSF shunt, in which radioisotopic scan correctly identified disconnection of the shunt tubing system localizing the site of extravasation accurately. The findings were confirmed by surgery performed for correction of the ...

We show two strategies which may be easily applied to standard abstract interpretation-based static analyzers. They consist in 1) restricting the scope of widening, and 2) intertwining the computation of ascending and descending chains. Using these optimizations it is possible to improve the precision of the analysis, without any change to the abstract domains.

Abstract The topology of vector fields offers a well known way to show a “condensed” view of the stream line behavior of a vector field. The global structure of a field can be shown without time-consuming user interaction. With regard to large data visualization, one encounters a major drawback: the necessity to analyze a whole data set, even when interested in only a small region. We show that...

In this paper we describe an implemented program for localizing the expression of many types of syntactic ambiguity, in the logical forms of sentences, in a manner convenient for subsequent inferential processing. Among the types of ambiguities handled are prepositional phrases, very compound nominals, adverbials, relative clatmes, and preposed prepositional phrases. The algorithm we use is pre...

The use of radioactive tumor-localizing antibodies is developed historically, starting with the demonstration that antibodies can be radioiodinated without destroying antibody activity. Then, antibodies against normal organs were shown to contain antibodies which localize in the normal organ. Subsequently, antibodies capable of localizing in tumors were demonstrated, and these localized well en...
