Background: Calprotectin is cytotoxic agent that its anti-tumor effects are governed through suppression of topoisomerase II a key enzyme in apoptosis. In previous studies, cytotoxicity and apoptotic effects of calprotectin are shown on different cancer cell lines, but not human gastric cancer cell lines. In the present study, cytotoxicity and apoptotic effects of calprotectin on human gastric ...

economists, sociologists and others have come to-this conclusion that the only element that eventually will determine the orientation of development, economic and social development of any country is the human resource. hence the physical capital and natural resources are not determinant one in this respect. the development of human resources which is the result of younger generation education ...

We consider the evaluation problem in Natural Language Generation (NLG) and present results for evaluating several NLG systems with similar functionality, including a knowledge-based generator and several statistical systems. We compare evaluation results for these systems by human domain experts, human non-experts, and several automatic evaluation metrics, including NIST, BLEU, and ROUGE. We f...

One of the main features of the human hand is its grasping ability. Robot grasping has been studied for years and different quality measures have been proposed to evaluate the stability and manipulability of grasps. Although the human hand is obviously more complex than robot hands, the methods used in robotics might be adopted to study the human grasp. The purpose of this ...

This article deals with evaluation of image quality by various methods and comparison of their results. Generally, there are several ways how to assess image quality. Three main approaches are: subjective testing, objective testing and image quality evaluation using a human visual system model (HVS). The subjective testing is based on human perception, the objective testing on a mathematical co...
