This paper raises and discusses three questions about the structure of Meaning-Text Theory, based on consideration of the role that paradigmatic Lexical Functions play in its model of the lexicon: Is the paradigmatic-syntagmatic distinction meaningful? Do paradigmatic LFs represent redundant semantic information (and if so, is the redundancy justified)? And finally, might definitions of lexemes...

Construction grammar offers a valuable tool for handling certain tricky cases that provide a challenge to MTT. In this paper, two such cases are examined, viz. ‘hybrid’ uses of nonmotion verbs in motion constructions and omissions of motion verbs resulting in verbless sentences. Finally, the procedure of how to incorporate a construction into the MTT framework is substantiated by means of verbs...

With the rising standard of the s ta te of the art in text generation and the increase of the number of practical generation applications, it becomes more and more important to provide means for the maintenance of the generator, i.e. its extension, modification, and monitoring by grammarians who are not familiar with its internals. However, only a few sentence and text generators developed to d...

Purpose: To develop a new method to estimate contrast agent (CA) extravasation directly from the tissue residue function derived from dynamic susceptibility contrast (DSC) MR imaging and to compare the method to a published method for extravasation correction in patients diagnosed with intraaxial brain tumors. Background: CA extravasation is a confounding factor is DSC imaging of brain tumors s...

Hypoprothrombinemia is a serious adverse effect of antimicrobial therapy that occurs after administration of some second- and third-generation cephalosporins which contain the methyltetrazole-thiol (MTT) group. Previous studies have shown that in vitro MTT directly inhibits microsomal gamma-carboxylation of a synthetic pentapeptide. Since MTT is a thiocarbamide, a type of compound that can incr...

A robust whole brain magnetic resonance (MR) bolus tracking technique based on indicator dilution theory, which could quantitatively calculate cerebral blood flow (CBF), cerebral blood volume (CBV), and mean transit time (MTT) on a regional basis, was developed and tested. T2*-weighted gradient-echo echoplanar imaging (EPI) volumes were acquired on 40 hyperacute stroke patients after gadolinium...

Senile plaques, a neuropathological feature of Alzheimer's disease, consist mainly of insoluble aggregates of pamyloid protein I I I . Using rat pheochromocytoma PC12 cells as an irr vitro model. i t has been shown that 8-amyloid potently inhibits the reduction of MTT 12.31. The cellular reduction of M 7 T is thought to be mediated by the mitochondrial respiratory chain, although other NAD(P)H ...
