A new method is described for measuring the mean transit time (MTT) of digesta through the human gut in which a constant amount of marker (radio-opaque pellets) is fed to subjects with each meal over a period of weeks, and its excretion measured in the stools. The MTT measured by this method (MTT-C) has been compared with MTT measured by giving single doses of similar markers to the same subjec...

BACKGROUND Pixel-based multimodality tissue tracking (MTT) is a new noninvasive method for the quantification of cardiac deformation from cine image of MRI. The aim of this study is to validate bi-ventricular strain measurement by MTT compared to strain-encoding (SENC) MRI and harmonic phase (HARP) MRI in pulmonary hypertension (PH) patients. METHODS In 45 subjects (30 PH patients and 15 norm...

One major method used to evaluate the biocompatibility of porous tissue engineering scaffolding materials is MTT (3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay. The MTT cell viability assay is based on the absorbance of the dissolved MTT formazan crystals formed in living cells, which is proportional to the number of viable cells. Due to the strong dye sorption capability ...

In this paper, we discuss the use of the Meaning-Text Theory (MTT) of [Mel88] in a controlled language (CL) application. We show that MTT defines a linguistic framework which is ideally suited for the definition and automation of CL rules. In the paper, we first briefly present a CL system based on MTT. We then discuss MTT in more detail. We show how CL-specific information can be represented s...
