Mona Ehab Aljaouni, Asmaa Ahmed Hafiz, Hadeel Hadi Alalawi, Ghaida Moazi Alahmadi, Imad AlKhawaja
Background: Self-medication is a common practice worldwide, particularly among adolescents and University students, and the irrational use of medicines is a cause of concern
Objectives: To assess students’ practices, knowledge, awareness and the reasons behind self-medication at Taibah University, Madinah, Saudi Arabia.
Subjects and Methods: A cross-sectional study was conducted from 1 June until 31 August (2015) at Taibah University, Madinah, Saudi Arabia. The study recruited 503 students of all academic years (349 medical and 154 non-medical students). The data were collected through a self-administered structured questionnaire. The questionnaire consisted of demographic data and data about students’ practice, attitude and reasons behind the use of self- medication. The collected data were analyzed using appropriate statistical methods. The level of statistical significance was defined as P ≤ 0.05.
Results: The prevalence of self-medication among the studied students was 64.8% (326 out of 503 students), and there was significant difference by students’ faculty, study year and family structure. The prevalence was higher among medical (66%), final years (75%), female (65.5%), and students living alone (77.8%). The self- medication students reported that they used un-prescribed medication to treat headache (35.9%), sore-throat and upper respiratory tract infections (42.9%), fever (14.1%), GIT problems (5.9%), and skin problems 91.2%). The most important self- medications used by students were analgesics (60.3%), antibiotics (30.6%), antipyretics (5.6%), vitamins (3.4%), and antihistamines (1.1%). The main source of information about medicines was the study books and learning experiences. The experience in self-medication was the most important reason of using self-medication in the studied students. However, most of the students (medical and non medical) reported non-favorable attitude towards self-medication and suggested health education and legislation to stop this phenomenon among university students.
Conclusions: The study finding revealed a high prevalence rate of self-medication among the studied students. The study findings address the crucial need to develop structured health education programs to prevent growing trend of self-medication among University students.

in Pure Form and Pharmaceutical Formulations
Amir AlHaj Sakur, Mohammed Samr Bassmajei, Hashem A. Dabbeet
Abstract: Moxifloxacin (MFX) is a synthetic broad-spectrum bactericidal 4th generation fluoroquinolone. At this study, three PVC membrane ion selective electrodes were constructed for MFX analysis purposes. The electro-active materials are MFX-tetraphenyl borate (MFX-TPB), MFX-Reineckate (MFX-RNK) or MFX-Nessler’s (MFX-NSR). The characterization and analytical properties were determined. The casting membranes were plasticized by di-n-butyl phthalate (DBP). The constructed electrodes have inner reference Ag/AgCl electrode. In addition, the assembled sensors have outer reference Ag/AgCl electrode. The sensors were near Nernstian response when the percentages ion pair at membranes were 6%, 4%, 6% for MFX-TPB, MFX-RNK, and MFX-NSR, respectively. The electrodes exhibited a fast dynamic response of 14-21 sec for a period of 10-13 days, without significant change in the electrodes parameters. The sensors worked at pH ranges 2.0-5.0, 2.0-5.5, and 2.0-6.0 for MFX-TPB, MFX-RNK, MFX-NSR sensors, respectively. The sensors have been used as indicator electrodes for direct determination of MFX in pharmaceutical preparations with mean relative standard deviation less than 2% indicating good precision, as well as in pure form solutions with average recovery of 98.58%, 99.09%, 99.27% and a mean relative standard deviation of 1.28, 1.81 and 1.91% at 0.438μg/ml MFX•HCl for MFX-TPB, MFX-RNK, and MFX-NSR sensors respectively.

Enterprise Ontology-based Information Systems Development
Tarek Fatyani , Junich Iijima, Jaehyun Park
Abstract: Information Systems Development (ISD) has encountered a variety of challenges in identifying complex requirements from multiple stakeholders. Therefore, users and their information environments have been a central issue for developing an abstract model of the early stages of information system development. To address this issue, modeling methodologies have considered modeling the enterprise as a social system. DEMO is a social system modeling methodology that addresses diverse social theories and multiple stakeholders’ requirements. Additionally, the DEMO model has improved not only the quality of the requirements but also reduced the time for implementation during the early stages of ISD. Therefore, this research focuses on developing an information system based on the DEMO model by deriving the conceptual artifacts of an IS from the DEMO model. Based on numerous real world projects, this study proposes that use of the DEMO model could lead to important discussions associated with actor roles, responsibility, and authority. These discussions are critical when defining the objectives and requirements of any information system to be developed.

Mohamed Alaa Ahmadou, Mohamad Sami JOHA
Objective(S): Cardiovascular disorder (CVD) is the major complication of type 2 diabetes. Tryptophan/kynurenine pathway has been related to CDV progression and diabetogenesis. In this paper, we will assess the presence of Kynurenine-modified serum proteins (KMSP) as a new predictor of CVD development in type 2 diabetes.
Materials and Methods: Peripheral blood was obtained from 189 participants. The diabetic patients were classified into two groups: group DC (included 63 type2 diabetic patients with CVD) and group D (included 63 type2 diabetic patients without CVD). The group N (normal people) included 63 volunteers’ people. The presence of KMSP was assessed by homemade-ELISA method using highly specific monoclonal antibodies.
Results: KMSP were significantly higher in diabetic patients and especially in DC group. Furthermore, KMSP level was only related with the onset of diabetes regardless of the presence of CVD.
Conclusion: KMSP predicted CVD in type 2 diabetes and might participate in CVD development.

Sensitive spectrophotometric methods for Determination of zolmitriptan in bulk form and in tablets via complex formation with tow sulphonphthalein acid dyes
Amir Alhaj Sakur, Reem Obaydo
Abstract: Two simple, sensitive and extraction-free spectrophotometric methods have been developed for the determination of zolmitriptan (ZMT) in pure form and in pharmaceutical formulations. The methods are based on the formation of yellow coloured ion-pair complexes between ZMT and two sulphonphthalein acid dyes, bromocresol green (BCG) method (A) and bromocresol purple (BCP) method (B) with absorption maximum at 411 nm and 403 nm for BCG and BCP, respectively. The stoichiometry of the complex in either case was found to be 1: 1. Reaction conditions were optimized to obtain the maximum colour intensity. Beer’s law was obeyed in the concentration ranges of 0.5–15.0and 0.375–12.0 μg/mL with BCG and BCP, respectively. The limits of quantification (LOQ) were 0.212 and 0.144 μg/mL for BCG and BCP methods, respectively . molar absorptivity (Ɛ) values were 24795, and 34548 L/moL.cm for BCG and BCP methods, respectively.The proposed methods have been applied successfully to the analysis of ZMT in pure form and in its dosage forms and no interference was observed from common excipients present in pharmaceutical formulations. Statistical comparison of the results with the reference method showed excellent agreement and indicated no significant difference in accuracy and precision.

The Trp64Arg Polymorphism in the ADRB3 Gene is Associated with Hypertension in Syrians
Hiba Kady, Mohammad Imad Balid, Mohammad Yaser Abajy
Abstract: Genes involved in the regulation of catecholamine function may be important in the development of hypertension. The β-adrenergic receptors importantly influence vascular reactivity and may regulate blood pressure. Genetic polymorphisms of the β-adrenergic receptors’ genes have been shown to alter the function of several adrenergic receptor subtypes and thus to modify the response to catecholamine. To determine if the common single nucleotide polymorphism (SNP) Trp64Arg in β3-adrenergic receptor gene (ADRB3) is associated with hypertension in adults, we recruited 78 individuals involving 37 healthy normotensive controls and 41 hypertensive patients who are between 36 and 70 years old in a case – control study which will be discussed in this paper. Results suggest that the Trp64Arg polymorphism contributes to hypertension in our population.
