Functional MRI and MR Spectroscopy Utilization in Jeddah Hospitals  [PDF]
Lamis K. Jada, Nabeel Mishah, Khalid Gh. Alsafi, Sarah Hagi, Mawya A. Khafaji, Hanan Y. Abbas, Saddig D. Jastaniah
Open Journal of Medical Imaging (OJMI) , 2015, DOI: 10.4236/ojmi.2015.53021
Abstract: Functional magnetic resonance imaging “fMRI” and magnetic resonance spectroscopy “MRS” are two crucial milestones that were introduced apart from one another into brain imaging and their implementation in major local cities is eventual step. Thus, the purpose of this study was to compare those techniques in terms of their clinical utilization in patient care delivery among the major governmental and private hospitals within Jeddah city. The study initially included eighteen hospitals to identify whether they were utilizing fMRI and MRS in their clinical practice. Out of the 18 hospitals under study only one hospital (5.6%) had both fMRI and MRS software; 7 (38.9%) had MRS but not fMRI; 4 (22.2%) did not have fMRI or MRS; and 6 (33.3%) hospitals had no MRI machine at all. Out of the eight hospitals applying MRS with one being excluded, the starting date of application was 2002 in 4 (57.1%) hospitals, 2004 in 1 (14.3%) hospital, and 2006 in 2 (28.6%) hospitals. The frequency of doing MRS was once a week in 2 (28.6%) hospitals, 2-3 cases/week in 3 (42.9%) hospitals, 5-10 cases/week in 1 (14.3%) hospital, and once every 6 months in 1 (14.3%) hospital. On the other hand, fMRI was applied only by one hospital starting in 2000 and was soon dismissed due to its time consumption and the inability of patients to accurately follow given instructions. It was concluded that MRS was more widely utilized compared to fMRI. Later on, a follow-up survey in the year of 2014 demonstrated that MRS has started to become a standard service in most hospitals whereas fMRI was still being unrecognized.
CT Optimization for Diagnosis of Some Acute Abdomen Cases  [PDF]
Saddig D. Jastaniah, Alamin M. Salih, Khalid Gh. Alsafi, Hamad Elniel H. Eltyib, Sarah Hagi, Maway A. Khafaji, Hanan Y. Abbas, Mohammad Alshihri
Advances in Computed Tomography (ACT) , 2015, DOI: 10.4236/act.2015.42003
Abstract:
The acute abdomen is one of the most frequent causes for presentation to the emergency department. Imaging plays an important role for an accurate diagnosis, which in turn diminishes morbidity and mortality. The aim of this study was to demonstrate optimum CT aspects and emphasize on the important features of CT for those patients presenting with an acute abdominal pain at the Emergency Department both in general and in a number of selected conditions (appendicitis, small-bowel obstruction, acute pancreatitis, and diverticulitis). The reported data by this study are based on the author working experience, which forms a continuous protocol adjustment process. The present study provides evidence that CT would result in definite diagnosis of patients with abdominal pain in terms of the detection of some urgent conditions.
Using Metaphors to Aid Student Meta-Learning: When You’re Learning at Your Best Your Like What?  [PDF]
Sarah Nixon
Creative Education (CE) , 2013, DOI: 10.4236/ce.2013.47A2006
Abstract:

Metaphors are widely discussed within educational research and this paper adds to the body of knowledge in relation to students using these as a tool to support meta-learning. Metaphors free up space for creative thinking by moving the mind from one place to another and have been found to be an effective cognitive device for learning. This project focuses on what students are like when they are “learning at their best” and discusses what knowing this information does for both individual self-awareness and working with others. Six final year students spent half a day exploring, developing and pictorially representing their “learning at best” metaphors. All six metaphors were different and showed the internal representations of the individuals when they were learning at their best. However out of the discourse common themes arose from the group in relation to what was needed to support learning these included time of day, mood, pace and environment. All six students were positive that the development of personal learning metaphors was beneficial and thought that it was important that these were developed systematically over time. The benefits were highlighted to be both for the individual working on their own and for understanding others in group work situations.

A Day in the Life of an Early Childhood Teacher: Identifying the Confronting Issues and Challenges That Arise  [PDF]
Sarah Ohi
Creative Education (CE) , 2014, DOI: 10.4236/ce.2014.511115
Abstract:

Recent emphasis upon Early Childhood as an educational priority for the Australian Government has resulted in increases in funding, government initiatives, course providers and the introduction of new policies to the sector in order to improve the quality of early childhood education. The study reported here investigated the “reality” of what it means to be an Early Childhood Teacher within this changing context and identified the roles and responsibilities and the associated challenges. A case study involving observation and interviews with five Bachelor qualified Teachers from varied early childhood settings was undertaken in order to gain knowledge about their experiences and perspectives on their work. The data were analyzed using a grounded theory approach involving the identification of key themes and issues about the nature of teachers’ work. The findings revealed that in their everyday practice teachers played a complex array of roles that required them to contribute far more than just their teaching skills and knowledge. They were expected to concurrently enact the roles of educator, leader, advocate, communicator, counsellor and administrator whilst juggling everyday challenges including a “lack of time”, the need for “further support and more resources” and “building successful partnerships with parents”.

Behavioural Sleep Disorders across the Developmental Age Span: An Overview of Causes, Consequences and Treatment Modalities  [PDF]
Sarah Lee Blunden
Psychology (PSYCH) , 2012, DOI: 10.4236/psych.2012.33035
Abstract: Behavioural sleep problems, that is, sleep problems that do not have a physiological aetiology, but rather a behavioural or psychological aetiology, are reported in between 20% - 40% of children and adolescents. These sleep disorders are categorised as Behavioural Insomnia of Childhood (BIC) in the International Classification of Sleep Disorders. BIC can result in short sleep duration and poor quality sleep and can have wide ranging effects on mental and physical health, cognitive and social functioning and development in infants, pre-schoolers, school aged children and adolescents. Each age group have a particular set of behaviourally based sleep disorders. This paper presents a broad overview of BIC and covers essential information about these sleep disorders, their aetiologies, effects on development and non medical treatment modalities.
Performance Study of a Distributed Web Server: An Analytical Approach  [PDF]
Sarah Tasneem, Reda Ammar
Journal of Software Engineering and Applications (JSEA) , 2012, DOI: 10.4236/jsea.2012.511099
Abstract: With the rapid expansion of the Internet, Web servers have played a major role in accessing the enormous mass of Web pages to find the information needed by the user. Despite the exponential growth of the WWW, a very negligible amount of research has been conducted in Web server performance analysis with a view to improve the time a Web server takes to connect, receive, and analyze a request sent by the client and then sending the answer back to client. In this paper, we propose a multi-layer analytical approach to study the web server performance. A simple client-server model is used to represent the WWW server in order to demonstrate how to apply the proposed approach. We developed a systematic, analytical methodology to quantify the communication delay and queuing overhead in a distributed web server system. The approach uses the Computation Structure Model to derive server processing time required to process a request sent from a client and queueing model to analyze the communication between the clients and the server.

Sarah Ibrahim, Souraya Sidani
Health (Health) , 2013, DOI: 10.4236/health.2013.511240
Abstract: Purpose: The purpose of this study was twofold: to examine the acceptability and preference for the two behavioral therapies, and to identify factors persons with chronic insomnia take into account when choosing treatment. Methods: The data were obtained in a large trial evaluating the effects of Stimulus Control and Sleep Restriction therapies. Prior to treatment, participants completed the treatment acceptability and preference (TAP) questionnaire, which described the Stimulus Control Therapy and the Sleep Restriction Therapy and requested participants to rate the acceptability of each treatment option before choosing one for the management of chronic insomnia. Open-ended questions were used to explore the factors that participants considered when making a choice. Results: Participants rated the Sleep Restriction Therapy as acceptable and 70.2% of participants preferred it over Stimulus Control Therapy. The factors that influenced participants’ choice related to the familiarity, previous personal experience, novelty, and suitability of the treatment. Conclusion: Persons have expressed a preference for treatments to manage chronic insomnia. Healthcare providers are in a position to provide relevant information about treatment options in order to help persons make informed treatment related decisions.
Fermented Milk Products from Different Milk Types  [PDF]
Olusola Ladokun, Sarah Oni
Food and Nutrition Sciences (FNS) , 2014, DOI: 10.4236/fns.2014.513133
Abstract: Yogurt was produced from milk obtained from cow milk, goat milk, soymilk and coconut milk by fermentation using starter cultures of Lactobacillus bulgaricus and Lactobacillus acidophilus.The results obtained showed that the initial pH of the fresh milk samples were slightly acidic: cow milk (6.3), goat milk (6.2), soymilk (6.4) and coconut milk (6.0). The pH results of the various fermented milk at 0 hour of production were goat milk (5.24), cow milk (5.85), soymilk (5.73) and coconut milk (5.98), but at 72 hours, all the milk samples tended to be more acidic due to the fermentation and had lower pH values. All the fresh milk samples had the high moisture content which ranged from 63.34% - 76.90%. Fat content ranged between 9.76% - 15.02%. Crude protein ranged from 7.17% - 32.17% with goat milk having the highest protein level of (32.17%). Ash content had the range of 0.52% - 0.96%. Goat milk had the highest ash content value and coconut milk had the least value. Specific gravities of soymilk, goat milk, cow milk and coconut milk were 1.018, 1.030, 1.016 and 1.01 g/ml respectively. Taste, color, mouth feel and odor were acceptable at 0 hours of production but their value depreciated with storage at room temperature. This study was able to establish the close nutritional gap between cow milk, goat milk, soya and coconut milk yoghurt preparations. The nutritional values obtained from the proximate analysis of the milk samples were comparable. This clearly points to the fact that either of the food can substitute for each other based on the values established from this study.
Effect of Bisphosphonate on Osteoclast of Bone  [PDF]
Sarah Ralte, Asima Bhattacharyya
Forensic Medicine and Anatomy Research (FMAR) , 2014, DOI: 10.4236/fmar.2014.23011
Abstract: Bisphosphonates are synthetic analogues of naturally occurring pyrophosphate molecule and are potent inhibitors of osteoclastic bone resorption. Bisphosphonates bind to hydroxyapatite crystals with high affinity and after incorporation by osteoclasts, the primary target cell, it inhibits osteoclastic bone resorption. The anti-resorptive effect has been shown to occur in organ culture as well as in-vivo, but the precise mechanism by which it exerts its bone resorbing effect is not yet fully understood. In vitro and in vivo studies have demonstrated that zoledronate is a more potent inhibitor of osteoclasts than earlier bisphosphonates. Bisphosphonates have now emerged as a leading therapeutic agent for the treatment of hypercalcaemia of malignancy, bone metabolic diseases, Paget’s disease and postmenopausal osteoporosis.
