An Efficient Method for Epileptic Seizure Detection in Long-Term EEG Recordings  [PDF]
Alaa Eldeen Mahmoud Helal, Ahmed Farag Seddik, Mohammed Ali Eldosoky, Ayat Allah Farouk Hussein
Journal of Biomedical Science and Engineering (JBiSE) , 2014, DOI: 10.4236/jbise.2014.712093
Abstract: Epilepsy is one of the most prevalent neurological disorders with no age, racial, social class, and neither national nor geographic boundaries. There are 50 million sufferers in the world today with 2.4 million new cases occur each year. Electroencephalogram (EEG) has become a traditional procedure to investigate abnormal functioning of brain activity. Epileptic EEG is usually characterized by short transients and sharp waves as spikes. Identification of such event splays a crucial role in epilepsy diagnosis and treatment. The present study proposes a method to detect three epileptic spike types in EEG recordings based mainly on Template Matching Algorithm including multiple signal-processing approaches. The method was applied to real clinical EEG data of epileptic patients and evaluated according to sensitivity, specificity, selectivity and average detection rate. The promising results illuminate that hybrid processing approaches in temporal, frequency and spatial domains can be a real solution to identify fast EEG transients.

Manal Kamel, Magdy El-Serafy, Hussein Attia, Hanan Abdeel-Haleem, Naglaa Zayed, Maha Hasab-Allah, Zakaria Salama
Open Journal of Gastroenterology (OJGas) , 2013, DOI: 10.4236/ojgas.2013.32017
Abstract:

Background: Although non-specific, transabdominal bowel ultrasonography, in real time or in color Doppler; has been beneficial in evaluating the location, extent and activity of inflammatory bowel disease (IBD). Aim: To assess the potential role of bowel transabdominal bowel ultrasonography in the diagnosis and follow-up of IBD. Patients and Methods: A cohort of 30 adults histologically-proven active IBD patients; ulcerative colitis (UC) (n = 20), Crohn’s disease (CD) (n = 10) were prospectively assessed in addition to 20 non-IBD participants representing the control group. All participants underwent the full colonoscopy in addition to real time and color Doppler ultrasonography. Bowel wall thickness, peri-enteric changes, and hemodynamic changes in the portal vein and mesenteric arteries were recorded at initial enrollment and after complete remission in 10 IBD patients. Results: Bowel wall was significantly thickened in all active IBD patients with a significant decrease after disease quiescence in CD patients; p value < 0.01. At initial evaluation, hypervascularization was evident in both mesenteric arteries among patients with active pancolitis and CD with significant differences; p value was <0.001 after disease quiescence. The diagnostic accuracy of UC and CD lesions ranged from 70% - 85%, 86% - 100% respectively. Conclusion: Transabdominal bowel ultrasonography supplemented with color Doppler study may represent a potential tool in the diagnosis, assessment of disease activity as well as follow-up of IBD.

Local Search-Inspired Rough Sets for Improving Multiobjective Evolutionary Algorithm  [PDF]
Ahmed A. EL-Sawy, Mohamed A. Hussein, El-Sayed Mohamed Zaki, Abd Allah A. Mousa
Applied Mathematics (AM) , 2014, DOI: 10.4236/am.2014.513192
Abstract:

In this paper we present a new optimization algorithm, and the proposed algorithm operates in two phases. In the first one, multiobjective version of genetic algorithm is used as search engine in order to generate approximate true Pareto front. This algorithm is based on concept of co-evolution and repair algorithm for handling nonlinear constraints. Also it maintains a finite-sized archive of non-dominated solutions which gets iteratively updated in the presence of new solutions based on the concept e-dominance. Then, in the second stage, rough set theory is adopted as local search engine in order to improve the spread of the solutions found so far. The results, provided by the proposed algorithm for benchmark problems, are promising when compared with exiting well-known algorithms. Also, our results suggest that our algorithm is better applicable for solving real-world application problems.

Maturity Assessment of Hospital Information Systems Based on Electronic Medical Record Adoption Model (EMRAM)— Private Hospital Cases in Iran  [PDF]
Masarat Ayat, Mohammad Sharifi
Int'l J. of Communications, Network and System Sciences (IJCNS) , 2016, DOI: 10.4236/ijcns.2016.911038
Abstract: Introduction: Today, information technology is considered as an important national development principle in each country which is applied in different fields. Health care as a whole and the hospitals could be regarded as a field and organizations with most remarkable IT applications respectively. Although different benchmarks and frameworks have been developed to assess different aspects of Hospital Information Systems (HISs) by various researchers, there is not any suitable reference model yet to benchmark HIS in the world. Electronic Medical Record Adoption Model (EMRAM) has been currently presented and is globally well-known to benchmark the rate of HIS utilization in the hospitals. Notwithstanding, this model has not been introduced in Iran so far. Methods: This research was carried out based on an applied descriptive method in three private hospitals of Isfahan—one of the most important provinces of Iran—in the year 2015. The purpose of this study was to investigate IT utilization stage in three selected private hospitals. Conclusion: The findings revealed that HIS is not at the center of concern in studied hospitals and is in the first maturity stage in accordance with EMRAM. However, hospital managers are enforced and under the pressure of different beneficiaries including insurance companies to improve their HIS. Therefore, it could be concluded that these types of hospitals are still far away from desirable conditions and need to enhance their IT utilization stage significantly.

Business and Economic Horizons , 2011,
Abstract: The present study has aimed at identifying the relationship between transformational leadership and job satisfaction of registered nurses at Jordanian private hospitals, the population of the study consisted of registered nurses at private hospitals located in Amman (capital of Jordan). There have been 200 surveys mailed out to registered nurses. One hundred and sixty eight usable surveys have been returned with an 83 % response rate. Regarding transformational leadership, the survey was adapted from the Multifactor Leadership Questionnaire (MLQ) (Avolio & Bass, 1995). The Minnesota Satisfaction Questionnaire (MSQ) developed by Weiss (1967) was adapted to measure the two factors of job satisfaction. The present study has shown a statistically significant positive relationship existing between the five dimensions of transformational leadership and the two dimensions of job satisfaction, the strongest relationship between internal job satisfaction and transformational leadership has been visible among the intellectual stimulation dimension.
Marrubiin
Olugbenga K. Popoola,Abdulrahman M. Elbagory,Farouk Ameer,Ahmed A. Hussein
Molecules , 2013, DOI: 10.3390/molecules18089049
Abstract: The ethno-medicinal approach to drug discovery represents one of the most important sources of new and safe therapeutic agents to the challenges confronting modern medicine and daily life. Many of the traditionally important medicinal plants contain active molecules or ones that serve as precursors to biosynthesised secondary metabolites to which the biological activity could be attributed. Marrubiin is one such compound and is a potential valuable compound which exists in high concentrations in many traditionally important Lamiaceae species which have demonstrated excellent pharmacological properties with commendably high safety margins. Marrubiin’s attributes include a low turnover, high stability and little catabolism, which are core characteristics required for therapeutic compounds and nutraceuticals of economic importance. In addition, marrubiin is considered a potential substrate for potent active compounds viz; marrubiinic acid, and marrubenol. The contribution of marrubiin to drug discovery thus needs to be put into prospective due to its ready availability, high potential applications and ease of modification. In this short review we highlight the most important chemical and pharmacological aspects reported on marrubiin since it was discovered.

PIER C , 2008,
Abstract: A compact elliptic-function low pass filter using microstrip stepped-impedance modified-hairpin resonators is developed and a multiple cascaded filter using semi-hairpin resonators is designed, analyzed and tested. Sharpness of cut off frequency, low insertion-loss, enhancement of bandwidth and very compact size are features of the proposed low-pass filter. Size reduction of this filter is reported about 62% with 13% enhancement of bandwidth respects to the conventional filter with comparable performance. The measurement results are in good agreement with the theoretical ones.
