Internal jugular vein morphology and hemodynamics in patients with multiple sclerosis

Abstract: AIM The aim of this study is to compare the hemodynamics and the morphology of the internal jugular veins using colour-Doppler and B-mode sonongraphy in multiple sclerosis patients (MS) and in controls. METHODS The internal jugular veins of 25 MS patients and 25 controls were examined using colour Doppler and B-mode ultrasound in sitting and supine positions, recording the changes in hemodynamics and the presence or absence of morphological changes. The presence of at least two of the extracranial Zamboni criteria in the same individual was considered positive for evidence of chronic cerebrospinal venous insufficiency (CCSVI). RESULTS According to the described criteria, 92% of the MS patients showed abnormal findings and 84% of them showed evidence of CCSVI, however; only 24% of controls showed abnormal findings, but none of them showed evidence of CCSVI (OR=7.25, 95% CI 2.92-18.01, P<0.0001). CONCLUSION Hemodynamic abnormalities and morphological changes involving the internal jugular vein are strongly associated with MS. These findings can be demonstrated by a non-invasive, cost effective Doppler ultrasound criteria.

Resource Efficient Mobile Computing Using Cloudlet Infrastructure

Abstract: Mobile Cloud Computing (MCC) has been introduced as a viable solution to the inherited limitations of mobile computing. These limitations include battery lifetime, processing power, and storage capacity. By using MCC, the processing and the storage of intensive mobile device jobs will take place in the cloud system and the results will be returned to the mobile device. This will reduce the required power and time for completing such intensive jobs. However, connecting mobile devices with the cloud suffers from the high network latency and the huge transmission power consumption especially when using 3G/LTE connections. In this paper, we introduce a Cloudlet based MCC system aiming to reduce the power consumption and the network delay while using MCC. We merged the MCC concepts with the proposed Cloudlet framework and propose a new framework for the MCC model. Our practical experimental results showed that using the proposed model reduces the power consumption from the mobile device, besides reducing the communication latency when the mobile device requests a job to take place remotely while keeping high quality of service stander.
