Vascular prostheses (grafts) are widely used for hemodialysis blood access, trauma repair, aneurism and cardiovascular reconstruction. However, smaller-diameter (≤4 mm) grafts that would be valuable many reconstructions have not been achieved to date, although hundreds of papers on small-diameter vascular published. This perspective article presents a hypothesis may open new research avenues th...

Nowadays, with the presence of technology in the human life, organizational levels have received a lot of changes which affected the operational aspects and the organizational structures from traditional to modern. Therefore, this study investigated the role of technology management to predict operational performance as the most important sources for gaining competitive advantages. It aimed to ...

Background: Since the general distrust of a new technology is an important obstacle in the development of this technology, attention to the ethical and social aspects of emerging technologies can play an important role in the development of these technologies. The present study uses documentary and library studies to examine the social and ethical aspects of new technologies with a focus on nan...

In this paper a modification of the time domain passivity controller is presented to improve its performance and transparency in case of multi degrees of freedom (dof) haptic interaction. In multi-dof application the concept needs to be extended by additional conditions to distribute the adaptive damping appropriately among the degrees of freedom. This can be solved by using the geometrical inf...

In 2014, balanced assessment systems (BAS) were proposed as a resource-conscious, 'fit-for-purpose' form of health technology assessment for middle-income countries which lack resources and competences necessary for resource-intensive health technology assessment models. BAS has undergone extensive policy debate in the period since its publication but it has not been critically assessed in a st...

OBJECTIVES Although ethics has been on the agenda in health technology assessment (HTA) since its inception, the integration of moral issues is still not standard and is performed in a vast variety of ways. Therefore, there is a need for a procedure for integrating moral issues in HTA. METHODS Literature review of existing approaches together with application of various theories in moral phil...

proteomics refers to the analysis of expression, localization, functions, posttranslational modifications, and interactions of proteins expressed by a genome at a specific condition and at a specific time. current proteomic tools allow large-scale, high-throughput analyses for the detection, identification, and functional investigation of proteome. in this review, we have focused on the proteom...
