Improvement of Praxis Skills in Children with Hemiplegic Cerebral Palsy by Using New Trend of Augmented Visual and Auditory Feedback Training: A Case Report  [PDF]
Safaa M. ElKholi, Reham S. Alsakhawi
Open Journal of Therapy and Rehabilitation (OJTR) , 2018, DOI: 10.4236/ojtr.2018.62004
Abstract: Aims: The aim of the study is to investigate if the new method of auditory and visual biofeedback as Upper Limb Exercise may improve praxis skills alone without any traditional physical therapy treatment or not and within three successive months of treatment in children with hemiplegic cerebral palsy. Methods: A 6-year-old hemiplegic cerebral palsied child was treated with Upper-Limb Exerciser as one of augmented visual and auditory feedback devices. Sensory Integration and Praxis test was used to measure a child’s ability to integrate sensory input for perception, motor planning, and spatial actions in; Space Visualization, Figure-Ground Perception, Standing and Walking Balance, Design Copying, Postural Praxis, Bilateral Motor Coordination, Constructional Praxis, Postrotary Nystagmus, Motor Accuracy, Sequencing Praxis, Oral Praxis, Manual Form Perception, Kinesthesia, Finger Identification, Graphethesia, Localization of Tactile Stimuli, and Praxis on Verbal Command. Results: The results revealed improvement of the major standard score for each of the 17 subtests of Sensory Integration and Praxis Test when compared after three successive treatment. Conclusion: The using upper limb exerciser as one method of augmented visual and auditory feedback can be used as one of the physical and occupational therapy programs aiming to improve praxis skills in hemiplegic cerebral palsied children.

Pakistan Journal of Nutrition , 2009,
Abstract: The effects of water extract of marjoram, chicory or mixture of both on some biological, biochemical and histological factors of hyperlipidemic obese rats were studied. Forty adult female rats were distributed into eight groups, the first one was kept as negative control, while the other seven groups were fed on high fat diet for induction of obesity. One of these groups was kept as positive control while the left 6 groups were orally given daily by stomach tube the 1 ml of water extract of marjoram, chicory or mixture of both at 5% and 10%, for 4 weeks. Results showed that isoflavones content in chicory water extract was higher than that of marjoram water extract. Body weight gain was markedly lower especially in the chicory and in mixture of marjoram and chicory groups (5% and 10%) compared to high fat diet control group. Oral administration of marjoram, chicory or their mixture water extracts at 5% and 10% lowered concentrations of total cholesterol, triglycerides, LDL-c, VLDL-c and decreased activity of AST and ALT enzymes. Furthermore, all extracts caused significant increase in HDL-c and T3 hormone concentrations except marjoram groups. Histopathological examination showed amelioration of histopathological lesions seen in liver of obese rats received the water extract of chicory or mixture of both. This study recommends that intake of water extract the mixture of marjoram and chicory especially at 10% because it may be useful for treating obesity accompanied by hyperlipidemia.

Journal of Cancer Therapy (JCT) , 2017, DOI: 10.4236/jct.2017.811091
Abstract: Purpose: Our prospective phase II trial aims to show the feasibility of adjuvant paclitaxel-based concurrent chemoradiotherapy (CCRT) following doxorubicin and cyclophosphamide (AC) to get the survival benefit of taxanes addition and avoid delay of radiotherapy. Patients and Methods: A total of 63 patients with pT1-2, and pN1-3, M0 breast cancer underwent conservative surgery followed by adjuvant 4 cycles AC followed by 4 cycles Paclitaxel 175 mg/m2 every 3 weeks. Adjuvant radiotherapy started during the first and second cycle of paclitaxel (CCRT). Toxicities evaluated at the base time, weekly during radiation therapy and every 3 months for 24 months for skin, pulmonary, cardiac, lymphedema, subcutaneous fibrosis and cosmoses. Survival reported at 2-year median follow-up. Results: At median follow up time of 24 months (6 - 30), we did not report any toxicity postpone or stop treatment and only two patients had grade III acute dermatitis. Fifty-two patients (82.5%) had satisfactory cosmoses and none of the patients developed local recurrence.
Is Post Operative Radiotherapy Justified for Completely Resected Locally Advanced Renal Cell Cancers?  [PDF]
Reham Abdulmoniem, Tarek Haikal, Hossam Darwiesh
Journal of Cancer Therapy (JCT) , 2013, DOI: 10.4236/jct.2013.49170
Abstract:

Background: There is an underutilization of postoperative radiation therapy (PORT) in renal cell carcinoma (RCC) following radical nephrectomy (RN). The main reason for that is the lack of strong evidence and the contradictory data in the literature regarding its benefit. We aimed to evaluate the efficacy of PORT in locally advanced patients with RCC following complete resection. Materials and Methods: The patients had RN and at least two of the poor prognostic factors like lymph nodes involvement (LN+), renal vein invasion (RVI), inferior vena cava invasion (IVCI) and renal capsule infiltration (RCI) were included in the study. Ninety-four patients were retrospectively evaluated; 56 patient received PORT 50Gy/25 fractions/5 weeks and 38 patients who did not receive PORT were compared. The LN+, RVI, IVCI and RCI were documented in 63 (67%), 46 (49%), 30 (32%) and 71 (76%) patients respectively. Results: Eight patients (14%) in PORT arm developed local recurrence (LR) are compared with 10 patients (26%) for non-PORT arm. Five-

Modified LAR Multicast Authentication Protocol
Reham Abdellatif Abouhogail
International Journal of Image Processing and Visual Communication , 2012, DOI: ijipvcv1i206
Abstract: Today there is a widening in digital technologies and increasing in new multimedia services like: pay-per-view TV, interactive simulations, teleconferencing. So there is an increasing demand for multicast communication. There is a number of security issues in multicast communication directly related to the specific nature of multicast. In this paper, we propose a new scheme for authenticating streamed data delivered in real-time over an insecure network we concentrate on the multicast authentication problem. Important requirements of multicast communication protocols are: to perform authentication in real-time, to resist packet loss to have low communication and computation overheads. In the present paper, a scheme for authenticating multicast data applications is proposed. The proposed protocol can be viewed as an improvement of LAR protocol (proposed by R.Latif et al in Jan 2011) [1]. The modified LAR doesn't assume the group members are honest as in LAR with lower communication overhead.
Women in Development: A Critique of Neo-Classical Economic Theory as One of the Causes for Gender Inequality  [PDF]
Reham El Morally
Open Journal of Political Science (OJPS) , 2020, DOI: 10.4236/ojps.2020.101001
Abstract: This research reviews and critiques neoliberalism and neoclassical economics for them being one of the main causes for the subordination and oppression of women. This research does not claim that neoliberalism is the axis of evil; however it discusses how alternative economic and political theories can be more useful and efficient for women and gender development. The research question is mainly concerned with how far do neoclassical economic theories perpetuate and intensify power struggle between genders? The research argues for neoclassical economic theory being a main driving force in the subordination and oppression of women, especially in global South countries that have been subjugated to structural adjustment. In order to do so, this research utilizes an intersectional feminist framework of analysis to methodologically deconstruct neoclassical economic theory and critically investigate their gendered effects on beneficiary countries. Moreover, the political conceptual framework of “inside-outside”, pioneered by Robert Cox, is the analytical tool used throughout this research. The research will, therefore, first clarify the difference between gender and sex, and clarify what I mean when I say neoclassical economic theory. Followed by a criticism
A Single-Tube RT-PCR Amplification for Detection of Rift Valley Fever Virus
Reham W. Salim,Khairalla M.S. Khairalla,Awadalkareem A. Eljamal,Abdelrahim E. Karrar,Imadeldin E. Aradaib
Research Journal of Medical Sciences , 2012, DOI: 10.3923/rjmsci.2010.146.151
Abstract: A reverse Transcriptase (RT) Polymerase Chain Reaction (RT-PCR) was developed and evaluated for detection of Rift valley fever virus in cell culture and serum samples from acute hemorrhagic fever cases. A pair of primers selected from the Medium (M) RNA gene segment of RVFV was used for RT-PCR amplification. The RT-PCR produced a 342-base pair (bp) from RVF RNAs extracted from smith burn vaccine strain propagated in vero cell culture and sera from infected humans and animals. However, the RT-PCR assay did not amplify the specific 342 bp product from RNAs extracted from closely related hemorrhagic fever viruses including Crimean Congo Hemorrhagic Fever Virus (CCHFV), Dengue virus, total RNA extracted from non infected vero cells. The described RT-PCR provides rapid, sensitive and specific method for detection of RVFV in cell culture and directly in serum samples. The RT-PCR assay should be recommended for inclusion during epidemiological surveys and outbreaks of the disease among humans and susceptible animal populations.

Reham Z. Sadek, Shereen M. Elbanna, Fayez M. Semida
Open Journal of Animal Sciences (OJAS) , 2013, DOI: 10.4236/ojas.2013.32A003
Abstract: Black bean aphid, Aphis fabae (Homoptera; Aphididae) is a serious pest causing crop loss. Plant-aphid interaction is a dynamic system subjected to continual variation and changes. Host plants induce various biochemical and physical defense mechanisms due to aphid feeding. Aphids can overcome plant defenses by enzymatic adaptations and sequestering secondary metabolites produced by the plant within their bodies as a defense against their enemies. Many strategies were developed and evolved by aphids in order to overcome plant defense barriers which allowed them to feed, grow and reproduce on their host plants. This study aimed to aid in better understanding of the effect of altering host plant on specialist and generalist aphid fitness.The influence of plant defense on population development of Aphis fabae was also investigated. Analyses for insect enzymes were also demonstrated in addition to further biochemical studies on host plant defences. Generalists showed different ecological and enzymatic adaptations towards host plants than specialist Aphis fabae. The results were fully discussed in details.

Int'l J. of Communications, Network and System Sciences (IJCNS) , 2015, DOI: 10.4236/ijcns.2015.85012
Abstract: The term “customer churn” is used in the industry of information and communication technology (ICT) to indicate those customers who are about to leave for a new competitor, or end their subscription. Predicting this behavior is very important for real life market and competition, and it is essential to manage it. In this paper, three hybrid models are investigated to develop an accurate and efficient churn prediction model. The three models are based on two phases; the clustering phase and the prediction phase. In the first phase, customer data is filtered. The second phase predicts the customer behavior. The first model investigates the k-means algorithm for data filtering, and Multilayer Perceptron Artificial Neural Networks (MLP-ANN) for prediction. The second model uses hierarchical clustering with MLP-ANN. The third one uses self organizing maps (SOM) with MLP-ANN. The three models are developed based on real data then the accuracy and churn rate values are calculated and compared. The comparison with the other models shows that the three hybrid models outperformed single common models.
