UNLABELLED Regional myocardial blood flow (MBF) can be measured with 15O-water and PET using the 1-tissue-compartment model with perfusable tissue fraction, which provides an MBF value that is free from the partial-volume effect. Studies with 15O-water have several advantages, such as the ability to repeat a scan. However, because of the short scanning time and the small distribution volume of ...

the application of laser in dentistry is considered as a favorable technique for patients due to its many advantages compare to other current methods. one of the main goals in pediatric dentistry is to provide the treatment as comfortable as possible without any risks for the care. laser is being used in different pediatric dental conditions including caries detection, caries removal and cavity...

We present a theory relating the static stress-strain properties of lung tissue strips to the stress-bearing constituents, collagen and elastin. The fiber pair is modeled as a Hookean spring (elastin) in parallel with a nonlinear string element (collagen), which extends to a maximum stop length. Based on a series of fiber pairs, we develop both analytical and numerical models with distributed c...

background in the living donor liver transplant setting, the preoperative assessment of potential donors is important to ensure the donor safety. objectives the aim of this study was to identify causes and costs of living liver-donors rejection in the donation process. materials and methods from june 2010 to june 2012, all potential living liver donors for 66 liver transplant candidates were sc...

stem cell research has obtained much prominence in recent years for its therapeutic potential in dealing with serious diseases, many of which are essentially incurable by routine therapies. mesenchymal stem cells with pluripotency and immunomodulatory properties are suitable candidates for tissue engineering and regenerative medicine. today, nanofibrous scaffolds are widely used in tissue engin...

human adipose tissue represents an abundant, practical and appealing source of donor tissue for autologous cell replacement. recent findings have shown that stem cells within the stromalvascular fraction of adipose tissue display a multilineage developmental potential. adipose tissue-derived stem cells can be differentiated towards adipogenic, osteogenic, chondrogenic,myogenic and neurogenic li...
