OBJECTIVE To investigate image quality and radiation dose of CT colonography (CTC) with adaptive iterative dose reduction three-dimensional (AIDR3D). METHODS Ten segments of porcine colon phantom were collected, and 30 pedunculate polyps with diameters ranging from 1 to 15 mm were simulated on each segment. Image data were acquired with tube voltage of 120 kVp, and current doses of 10 mAs, 20...

BACKGROUND The Modified Ashworth Scale (MAS) is the most popular clinical measure of spasticity. Other clinical signs of spasticity include hyperactive tendon reflexes, myoclonus and Babinski sign. PURPOSE To assess reliability of the MAS with myoclonic and tendon reflex examination (MTR) in patients with spinal cord injury (SCI). MATERIAL AND METHODS 30 patients (16 with complete and 14 wi...

Whether an agent can be a collection of several interacting agents, a hierarchy, or some other type of organization? We believe that several difficult challenges for automated systems can be tackled by giving full meaning to the MAS concept: adopting a recursive definition of agents. In this work, we propose a definition of MAS beliefs in terms of its constituent agents' beliefs.

OBJECTIVES The purpose of our study was to detect early clinical and laboratory signs that help to discriminate macrophage activation syndrome (MAS) from active systemic juvenile idiopathic arthritis (SJIA) without MAS. METHODS Our retrospective study was based on reviewing the medical charts of the children admitted to the rheumatology department with active SJIA and definite MAS (n = 18) an...

A Multi-Agent System (MAS) can be viewed as a software system evolving in some environment, with which it has to interact. During the MAS life cycle, many situations may occur, situations that are considered to be critical and that would have an effect on the MAS, prompting it to quickly adjust to this new situation. A design methodology of a MAS should help the designer to represent informatio...

One aspect of multi-agent systems (MAS) that has been only partially studied is their role in software engineering, and in particular their merit as a software architecture style. As we demonstrate, multi-agent systems developed to date have several common architectural characteristics, even though differences in their design and implementation result in variations in their strengths and weakne...

The Mas receptor is a class I G-protein-coupled receptor that is expressed in brain, testis, heart, and kidney. The intracellular signaling pathways activated downstream of Mas are still largely unknown. In the present study, we examined the expression pattern and signaling of Mas in the heart and assessed the participation of Mas in cardiac ischemia-reperfusion injury. Mas mRNA and protein wer...

Propagation of signals from G protein-coupled receptors (GPCRs) in cells is primarily mediated by protein-protein interactions. MAS is a GPCR that was initially discovered as an oncogene and is now known to play an important role in cardiovascular physiology. Current literature suggests that MAS interacts with common heterotrimeric G-proteins, but MAS interaction with proteins which might media...

Despite the considerable efforts researching and developing Multi-Agent Systems (MAS) there is a noticeable absence of deployed systems. In the past the MAS research community ignored this problem arguing that it is not a genuine MAS problem and consequently of lesser importance than other unsolved issues like cooperation, coordination, negotiation and communication. However, as the field matur...
