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...

Background: MTT assay is a colorimetric test to evaluate cell metabolic activity of living cells via reduction the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide insoluble formazan crystals by mitochondrial activities. The tetrazolium dye thought occur NADPH-dependent oxidoreductase enzymes in cytosol. used measure cytotoxicity or cytostatic generally plant and chemical compounds ...

Mixing the residue in the gut has been studied in 24 normal subjects using five different types of radio-opaque pellets. By giving single doses of different pellets to the subjects on three successive days and measuring their appearances in the stool by radiographs evidence of mixing was found in 83% of studies. Mean transit time (MTT) of markers through the gut was measured from the single dos...

آلیاژهای منیزیم معمولاً دارای عدم تقارن تسلیم در حالت کشش و فشار هستند که این عامل ناشی از سازوکارهای مختلف تغییر شکل پلاستیک فعال تحت بارگذاری‌های کششی فشاری است. مقاله بر روی شبیه‌سازی المان حجمی نماینده‌ی سه‌بعدی آلیاژ اکسترود شده تمرکز دارد تا با کمک روابط کریستال پلاستیسیته تأثیر شدت بافت پایه ـ را بررسی کند. پلاستیسته مبتنی‌بر لغزش به‌صورت یک زیربرنامه نرم‌افزار آباکوس (U‌M‌A‌T) برای آزمون...

The hydrogen acceptor 3-(4,5-dimethylthiazol-2-yl)-2,5 dipheny Itetrazolium bromide (Mil) is commonly utilized to estimate cellular viability in drug screening protocols. The present investigation was prompted, in part, by observations that reduction of MTT to its colored reaction product, MTT formazan, varied between cell lines and with culture age. A correlation was established between the D-...
