Abstract
Deficiency in the membrane-bound complement regulators CD55 and CD59 exacerbates renal ischemia-reperfusion injury (IRI) in mouse models, but the effect of increasing CD55 and CD59 activity has not been examined. In this study, we investigated the impact of overexpression of human (h) CD55 ± hCD59 or treatment with soluble rhCD55 in a mouse model of renal IRI. Unilaterally nephrectomised mice were subjected to 18 (mild IRI) or 22 min (moderate IRI) warm renal ischemia, and analyzed 24 h after reperfusion for renal function (serum creatinine and urea), complement deposition (C3b/c and C9), and infiltration of neutrophils and macrophages. Transgenic mice expressing hCD55 alone were protected against mild renal IRI, with reduced creatinine and urea levels compared with wild type littermates. However, the renal function of the hCD55 mice was not preserved in the moderate IRI model, despite a reduction in C3b/c and C9 deposition and innate cell infiltration. Mice expressing both hCD55 and hCD59, on the other hand, were protected in the moderate IRI model, with significant reductions in all parameters measured. Wild type mice treated with rhCD55 immediately after reperfusion were also protected in the moderate IRI model. Thus, manipulation of CD55 activity to increase inhibition of the C3 and C5 convertases is protective against renal IRI, and the additional expression of hCD59, which regulates the terminal complement pathway, provides further protection. Therefore, anti-complement therapy using complement regulatory proteins may provide a potential clinical option for preventing tissue and organ damage in renal IRI.

ABSTRACT

Introduction
An array of odontogenic lesions manifest in the maxillofacial region with variable presentations. The biological behavior of lesions, such as odontogenic keratocyst (OKC), dentigerous cyst (DC), and ameloblastoma (AM) always invite debate. Glucose transporter 1 (GLUT-1) is proven to be an indicator of metabolic behavior of several benign and malignant neoplasms.

Aim
The purpose of this study was to evaluate the expression of GLUT-1 in OKC, DC, and AM to understand their metabolic behavior.

Materials and methods
Immunohistochemical expression of GLUT-1 was evaluated in each of the 15 cases of OKC, DC, and AM. The number of labeled cells, staining intensity, and membrane or cytoplasmic expressions were the parameters assessed and analyzed using chi-square test.

Results
All cases showed positive GLUT-1 expression: 86.6% OKC showed more than 50% labeled cells followed by DC (40%) and AM (26.5%); 53.3% OKC showed strong intensity in comparison to AM, which showed weak intensity in 53.3% cases; 86.6% of OKCs showed both membrane and cytoplasmic expression followed by DC (40%) and AM (26.6%), whereas 73.3% of AM showed only membrane expression followed by DC (60%) and OKC (13.3%).

Conclusion
Odontogenic keratocyst was found out to be more metabolically active followed by DC and AM.

Published: May 2017

ABSTRACT

Introduction
Osteoporosis is a systemic bone disease that can be prevented to some extent by awareness of its risk factors and related health behavior. The aim of this study was to collect information about knowledge and awareness of osteoporosis among women living in Jazan and to describe the type of food habits, sociodemographic characteristics, and other osteoporosis- related health behavior.

Materials and methods
Self-administered questionnaires were used for data collection. The total participants were 546 women: 88 (16.1%) were health professionals and 458 (83.9%) non health professionals in the age range ≤20 to 50 years. Data collection was facilitated by a trained intern female doctor of dentistry whose task was to administer the distribution and collection of the questionnaires.

Results
In total, 61.9% of health professionals and 54.3% of nonhealth professionals scored highly on knowledge of osteoporosis. The respondents of osteoporosis preventive food items were also highly knowledgeable with 50.6 and 52.6% of health and nonhealth professionals respectively. About 48.1% of health professional and 44.2% of nonhealth professional scored low on knowledge of osteoporosis behavior and attitude, vitamin supplements, and sunlight exposure. The age effect on osteoporosis knowledge was 33.8% in young age group and 30.7% in old age group.

Conclusion
Our study shows that Jazan women were highly knowledgeable and aware about osteoporosis and its related health behavior and that health professionals and nonhealth professionals were equally aware about osteoporosis-related health matters.

Clinical significance
Awareness and preventive behavior of osteoporosis can prevent or slow the development of the disease.

ABSTRACT

Aim
The aim of this preliminary study was to assess the chance of dental caries level using early childhood oral health impact scale (ECOHIS) in a group of 5-year-old children in Sri Lanka.

Materials and methods
A sample of school children aged 5+ years was taken for the study from Denuwara educational zone in Kandy District in Sri Lanka using probability proportional to size sampling method in 2010. Dental caries and oral health impact of the children were recorded. The mean decayed, missing, and filled teeth (DMFT) was 0.01 ± 0.3, while mean dmft was 3.7 ± 0.29. The mean decayed teeth (d) was 3.0 ± 0.23, the mean extracted teeth (m) was 0.46± 0.08, and the mean filled teeth (f) was 0.21 ± 0.05. Twenty four percent of them were caries free (95% confidence interval 0.17, 0.32). Ordinal logistic regression models were fitted by considering dmft levels as the response variables, and oral health impact as the predictor variable. Since Pearson test p-value and deviance test p-value are 0.99 (p > 0.05) and 0.986 (p > 0.05) respectively, the null hypothesis is not rejected as the model fitted the data adequately.

Conclusion
This model could be used to predict the chance of dental caries level with the score of ECOHIS. Therefore, ECOHIS can be taken as a reliable indicator to assess the level of dental caries.

Authors: Kapri Anita , Joshi Sudhir 
Published: May 2017

ABSTRACTDental implants have been a universally accepted option for prosthetic rehabilitation of partially edentulous patients. Titanium implants abutments exhibit a dull grayish hue and give an unnatural appearance. Abutments based on zirconia are one of the alternatives to titanium abutments. To date, few comparative studies have reported on esthetic and biological outcomes of implant-supported restorations with zirconia abutments.PurposeTo clinically evaluate the esthetic performance of zirconia abutments in implant-supported restorations.Materials and methodsA total of 24 anterior implant sites were chosen for the placement of implants. A delayed loading protocol was followed; 12 zirconia abutments were placed along with 12 titanium abutments in the contralateral sites. Biological and esthetic variables were recorded by a periodontist and prosthodontist. The patients were followed 2 weeks, 1, 3, and 6 months postinsertion.ResultsAll the data for Copenhagen index score and visual analog scale scores were evaluated by the prosthodontist at follow-up appointments; the means were tabulated. The data were statistically analyzed using Statistical Package for the Social Sciences software utilizing paired t-test; p value was found to be significant for all parameters except distal papilla and symmetry, which showed p = 0.257 and p = 0.110 respectively.ConclusionAccording to the results of this study, esthetic performances of zirconia abutment in implant-supported restorations were determined to be higher than those values associated with titanium abutments.How to cite this articleKapri A, Gupta A, Joshi S.

Authors: Bhagwat Sumita , Sheth Nehal 
Published: May 2017

ABSTRACTIntroductionPostoperative pain is a major concern for patients undergoing root canal treatment. Much research has gone into the alteration of several variables to determine the elusive technique that will result in no postoperative pain.AimThe aim of our study was to investigate the incidence, severity, and duration of postoperative pain in relation to technique of root canal preparation and compare the difference in incidence, severity, and duration of postoperative pain in single- and two-sitting root canal therapy when different instrumentation techniques are used.Materials and methodsSixty adult patients requiring root canal therapy were selected and divided into six groups. Singlesitting root canal treatment was carried out in three groups, with three different canal preparation methods (group I – Conventional hand files, group II – hand ProTaper files, and group III – rotary ProTaper files). Two-sitting root canal treatment was carried out in three groups, with the same canal preparation methods (group IV – conventional hand files, group V – hand ProTaper files, and group VI – rotary ProTaper files). Postoperatively, the subjects were instructed to fill out a series of self-report questionnaires for pain incidence after 1 day, 2 days, 3 days, 1 week, and 2 weeks. After 2 weeks, the patients were recalled and their responses were duly noted.ResultsResults were tabulated and statistically analyzed using Mann–Whitney U test.ConclusionThere was a significant difference in incidence, character, and duration of postoperative pain in rotary-prepared canals as compared with hand-prepared canals in both singleand two-sitting endodontics.Clinical significanceThe purpose of this study was to search for a predictability in incidence, duration, and character of postoperative pain in canals instrumented with hand and rotary instruments. Knowing this will enable clinicians to make more prudent choices in instruments, techniques, and protocols for root canal therapy.How to cite this articleBhagwat S, Sheth N, Padhye L.

Authors: Rahman Mohammad Anisur , Islam Md. Aminul , Qi Xu 
Published: May 2017

Garment industry can be considered as the sprinter of the economy in Bangladesh for its significant contribution to the economy. Demand for Bangladeshi garments products are increasing so are the competitions. The garment industry, to keep pace with the increasing competition, needs to adopt Information System (IS) in business functions that help ensure cost management effectively in the labor-intensive garments factory. However, very few garments factories have adopted IS in their operations. This paper tried to identify the factors inhibiting the adoption of HRIS in the garments industry of Bangladesh through a semi-structured questionnaire survey of 150 samples from 25 garment factories in Bangladesh. We have used Exploratory Factor Analysis (EFA) method to identify the factors impeding to adopt HRIS in garments sector of Bangladesh. From the study, we have identified three broad inhibiting factors termed as Financial, Management related, and Organizational; specifically, High investment, Costly maintenance, Long-term benefit, Organizational Structure, Culture of the Organization, Top management support, lack of experts and user, are found as major barriers in this regard. The findings may be useful to both the academicians to explore the factors in their respective countries and the HRIS practitioners in garment sector to emphasize on these areas so that organizations can ensure better HRIS implementation.
English Language Motivation between Gender and Cultures
Authors: Al Harthy Said Rashid 
Published: May 2017

Abstract
This study investigates the effects of the socio-cultural factors on the motivation of female and male students in 14 Arab and non-Arab countries through 14 studies. The findings indicate that both genders in the two groups share some interests of motivation for learning English, but they differ in some cultural factors that influence or hinder their learning. The findings of this research found that female students′ integrative motivation and attitudes towards English are higher than male students. The present study suggests a serious need for conducting qualitative or mixed method studies to investigate this phenomenon and to propose practical alternatives to increase male students' language motivation to learn English especially the integrative type. Pedagogical implications for teachers and suggestions for further research are included.

Published: May 2017

Abstract
The aim of this paper is to give some general views on international labour standards, regarding equality of opportunity and treatment. It is important to mention that respecting freedom from discrimination, as a fundamental human right, places a great importance in guaranteeing other rights for workers. Equality standards applied by ILO provide methods which aim to fight against discrimination in society and in the workplace of the employers. One part of this paper is focused in analyzing the term “discrimination”, focusing in different forms that can occur at work, the target group which it can affect and measures that can be taken in order to provide equality at work. This paper analyses the scope and the obligations under ILO instruments, such as three fundamental conventions. One of the most important conventions is the convention concerning discrimination regarding occupation and employment, “Discrimination Employment and Occupation” Convention nr. 111. This fundamental convention represents discrimination as every different treatment which has effect on equality of creating same possibilities for everyone in occupation or employment. According to this legal act, it is mandatory the implementation of a national legislation which promotes equality of treatment and opportunity, regarding occupation and employment in general, designed to eliminate all types of different treatment in these fields. This paper is focused especially on analyzing the “Workers with Family Responsibilities” Convention, 1981, which refers to standards on equal treatment and opportunities for both women and men workers. “Workers with Family Responsibilities” Convention, applies to workers with such responsibilities, which restrict their possibilities to involve in an economic activity. The purpose is to provide an effective implementation of standards related to equality of treatment and opportunity for both women and men workers, in order to guarantee free choice of employment to help workers which have family responsibilities and to take into consideration their needs. Furthermore in this paper will be identified the methods that governments should apply, which aim to provide the application of the standard of equal compensation for workers, according to “Equal Remuneration” Convention, 1951 (No. 100).
Record Linkage using Probabilistic Methods and Data Mining Techniques
Authors: Elezaj Ogerta , Tuxhari Gloria 
Published: May 2017

Abstract
Nowadays corporations and organizations acquire large amounts of information daily which is stored in many large databases (DB). These databases mostly are heterogeneous and the data are represented differently. Data in these DB may simply be inaccurate and there is a need to clean these DB. The record linkage process is considered to be part of the data cleaning phase when working with big scale surveys considered as a data mining step. Record linkage is an important process in data integration, which consists in finding duplication records and finding matched records too. This process can be divided in two main steps Exact Record Linkage, which founds all the exact matches between two records and Probabilistic Record Linkage, which matches records that are not exactly equal but have a high probability of being equal. In recent years, the record linkage becomes an important process in data mining task. As the databases are becoming more and more complex, finding matching records is a crucial task. Comparing each possible pair of records in large DB is impossible via manual/automatic procedures. Therefore, special algorithms (blocking methods) have to be used to reduce computational complexity of comparison space among records. The paper will discuss the deterministic and probabilistic methods used for record linkage. Also, different supervised and unsupervised techniques will be discussed. Results of a real world datasets linkage (Albanian Population and Housing Census 2011 and farmers list registered by Food Safety and Veterinary Institute) will be presented.

Authors: Issahaku Paul Alhassan 
Published: May 2017

Abstract
The aim of this study was to assess the extent to which background characteristics, students’ attitudes to learning, and students’ use of social media influence academic performance among undergraduates in Ghana. It was hypothesized that previous performance, hours of study, family income, having a personal study schedule, attending lectures regularly, participating in class discussions, taking notes during lectures, use of alcohol, and use of social media, among other factors will influence a student’s grade point average (GPA). Questionnaires were distributed to 1,500 students across four universities, of which 626 completed questionnaires were returned (N = 626). Correlation analysis showed that only hours of study was strongly related to GPA (r = .1, p = .05). Independent-samples t tests showed that students who had personal study schedules, attended lectures regularly, participated in class, took notes, chatted on Facebook, did not use alcohol, regarded a higher GPA as important, and who lived Off-campus, respectively, had a higher mean GPA. The study has contributed to the literature on factors that affect undergraduate academic performance in Ghana by investigating the effect of several demographic and attitudinal factors on student GPA. The findings indicate that to enhance academic performance it is important to influence students’ attitudes and dispositions toward learning, including lecture attendance, participation in class, self-initiated or independent learning, use of social media, and abstinence from alcohol.

Abstract
This work investigated the management of biodegradable waste among residents in a South-East Locality of Nigeria. The design adopted was descriptive survey design. The population size was 270,902 residents in Ahiazu Mbaise Local Government Area. The sample for the study consisted of 840 respondents selected using a multi-stage procedure. Four objectives guided the study. The data collected were analyzed using descriptive statistics of frequency tables and simple percentages. The study revealed that majority(706; 84&%) of the residents agreed on the common types of biodegradable waste generated; majority use broom and bare hand (hand picking) to collect biodegradable waste with the frequencies of 648 (77%) and 560 (67%)respectively; majority agreed on the methods of transporting biodegradable waste with an overall frequency of 584 (70%) and that majority agreed the methods of disposal of biodegradable waste with an overall frequency of 632 (75%). Based on these, it was recommended among others that health educators should be employed in the ministry of environment with mandate of organizing health talks for the residents to enlighten them on the management of biodegradable and that government should provide adequate means and facilities for the management of waste in our surroundings.
