Traditionally, sleep is monitored based on PSG signals that require several measurements collected from different locations on the head and the body. These signals are used to evaluate the sleep quantity and quality. However, the need for unobtrusive monitoring and convenience motivates a variety of alternative approaches focused on the minimization of a number of monitored physiological signals. Previous studies have shown that the quantity and length of slow wave sleep (SWS) periods during sleep are the major indicators of the sleep quality. The aim of this paper is to present a new automatic method to detect SWS epochs using a single-channel electro-oculography (EOG). This method is based on a simple rule based algorithm with an adaptive method to adjust thresholds. The new method is evaluated through 9 healthy subjects and the results are compared to the clinical visual scoring. The agreement of our detection method for the validation data was 90.0%, the sensitivity was 90.5% and the specificity was 89.9% and the kappa value was 0.74.","PeriodicalId":384055,"journal":{"name":"2nd Middle East Conference on Biomedical Engineering","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130864095","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mice bearing established RCC xenograft tumors were treated with sunitinib doses of 10, 20 or 40 mg/kg/day (SU10, SU20 or SU40 respectively) or treated with vehicle only (control). New DCE parameters, contrast agent uptake to the peak (AUCtp), time to peak concentration (TTP), washout slope (Nslope) and full width half maximum (FWHM), were obtained from T1-weighted images. These parameters were quantified for tumor-bearing kidneys and normal kidneys. Treatments with SU20 and SU40 caused increased perfusion in the tumor core compared to control and SU10. Kidney tumors treated with SU20 had an almost identical pattern of contrast agent uptake rate, peak and clearance as those observed in normal kidneys. The effect of SU20 on normal kidneys was milder than that observed with SU40. Treatment with SU40 caused increased contrast agent uptake by the cortex of the normal kidneys compared to the normal kidneys in control and SU10. FWHM also provided new information about the effect of different treatment doses and showed that kidney tumors treated with SU20 have almost the same values of FWHM as the normal kidneys in control mice. The new DCE parameters, including AUCtp, Nslope and FWHM, have the potential to give a precise description of the treatment effect not only in the whole mouse kidney but also in different regions inside the kidney.","PeriodicalId":384055,"journal":{"name":"2nd Middle East Conference on Biomedical Engineering","volume":"580 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115896914","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of applicable control signals for controlling a powered prosthesis is the myoelectric signal. A number of commercial products have been developed that utilize myoelectric control for powered prostheses; however, the functionality of these devices is still insufficient to satisfy the needs of amputees. For the purpose of a comparison, several electromyogram classification methods have been studied in this paper. The performance criteria included not only classification accuracy, but also repeatability and robustness of the classifier, training time for online training performance, and computational time for real-time operation were evaluated with seven classification algorithms. The study included five different feature sets with time-domain feature values and autoregressive model coefficients. In summary, the quadratic discriminant analysis showed a remarkable performance in terms of high classification accuracy, high robustness, and low computational time of training and classification from the experiment results.","PeriodicalId":384055,"journal":{"name":"2nd Middle East Conference on Biomedical Engineering","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128249253","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
