10 Novel Electrospun Polymeric Nanofibers Loaded Different Medicaments as Drug Delivery Systems for Regenerative Endodontics

Authors: Nura Brimo, Dilek Cokeliler Serdaroglu, Tansel Uyar, Busra Uysal, Elif Bahar Cakici, Miris Dikmen, Zerrin Canturk

Abstract:

Background: A combination of antibiotics, including metronidazole (MET), ciprofloxacin (CIP), and minocycline (MINO), has been demonstrated to disinfect bacteria in necrotic teeth before regenerative processes. It has been presented clinically that antibiotic pastes may drive to possible stem cell death and difficulties in removing from the canal system, which can limit the regenerative procedure. This study was designed to (1) synthesize nanofibrous webs containing various concentrations of different medicaments (triple, double, and calcium hydroxide,Ca(OH)2), and (2) coat thiselectrospun fibrous gutta-percha (GP) cones. Methods: Poly(vinylpyrrolidone) (PVP)-based electrospun fibrous webs were processed with low medicaments concentrations. Scanning Electron Microscopy (SEM), Energy Dispersive X-Ray Spectroscopy (EDX), and X-Ray Photoelectron Spectroscopy (XPS) were carried out to investigate fiber morphology, antibiotic incorporation, and characterized GP-coated fibrous webs, respectively. The chemical and physical properties of dentine were carried out via Fourier Transform Infrared Spectroscopy (FTIR) and Nano-SEM, respectively. The antimicrobial properties of the different fibrous webs were assessed against various bacteria by direct nanofiber/bacteria contact. Cytocompatibility was measured by applying the MTT method. Results: The mean fiber diameter of the experiment groups of medicament-containing fibers ranged in the nm scale and was significantly smaller than PVP fibers. EDX analysis confirmed the presence of medicaments in the nanofibers. XPS analysis presented a complete coating of the fibers with GPs; FTIR and Nano-SEM showed no chemical and physical configuration of intracanal medicaments on the dentine surface. Meanwhile, nanofibrous webs led to a significant reduction in the percentage of viable bacteria compared with the negative control and PVP. Conclusion: Our findings suggest that TA-NFs, DA-NFs, and Cₐ(OH)₂)-NFs coated GP cones have significant potential in eliminating intracanal bacteria, cell-friendly behavior, and clinical usage features.

9 Nigerian Foreign Policy: A Dancing Tune of the Western Powers

Authors: Nura Suleiman

Abstract:

The foreign policy of any country or nation is intended to promote and protect the country’s national interest. To achieve this interest, a country has to be guided by certain principles and influence of domestic and international conditions. The history of Nigerian foreign policy is directed to defend its sovereignty, independence, and territorial integrity, to promote and sustain the economic well-being of Nigerians, and promotion of Africa and world peace with justice. With the change of time and leadership, coupled with corruption, despite all the foreign policy determinants endowed with Nigeria as a country, sacrificed its foreign interest for the benefit of the western powers, by this it lost the opportunity to formulate policies according to its own need and desires.

8 EhfadHaya (SaveLife) / AateHayah (GiveLife) Blood Donor Website

Authors: Sameer Muhammad Aslam, Nura Said Mohsin Al-Saifi

Abstract:

This research shows the process of creating a blood donation website for Oman. Blood donation is a widespread, crucial, ongoing process, so it is important that this website is easy to use. Several automated blood management systems are available, but none provides an effective algorithm that takes into account variables such as frequency of donation, donation date, and gender. In Oman, the Ministry of Health maintains a blood bank and keeps donors informed about the need for blood through a website. They also inform donors and the wider public where and when is their next blood donation event. The website's main goals are to educate the community about the benefits of blood donation. It also manages donor and receiver documentation and encourages voluntary blood donation by providing easy access to information about blood types and blood distribution in various hospitals in Oman, based on hospital needs.

7 Influence of Locally Made Effective Microorganisms on the Compressive Strength of Concrete

Authors: Muhammad Nura Isa, Magaji Muhammad Garba, Dauda Dahiru Danwata

Abstract:

A lot of research was carried out to improve the technology of concrete, some of which include the introduction of new admixture in concrete production such as effective microorganisms. Researches carried out in Japan and Malaysia indicated that the Effective Microorganisms improve the strength and durability of concrete. Therefore, the main objective of this research is to assess the effect of the locally made effective microorganisms on the compressive strength of concrete in Nigeria. The effective microorganisms were produced locally. The locally made effective microorganism was added in 3%, 5%, 10% and 15% to replace the mixing water required. The results of the tests indicated that the concrete specimens with 3% content of locally made EM-A possessed the highest compressive strength, this proved the 3% to be the optimum dosage of locally made EM-A in the concrete.

Authors: Shamsu Abdullahi, Nazir Yusuf, Hazrina Sofian, Abubakar Zakari, Amina Nura, Salisu Suleiman

Abstract:

Requirements negotiation process models help in resolving conflicting requirements of the heterogeneous stakeholders in the software development industry. This is to achieve a shared vision of software projects to be developed by the industry. Negotiating stakeholder agreements is a serious and difficult task in the software development process. There are many requirements negotiation process models that effectively negotiate stakeholder agreements that have been proposed by the research community. Other issues in the requirements negotiation research domain include stakeholder communication, decision-making, lack of negotiation interoperability, and managing requirement changes and analysis. This study highlights the current state of the art in the existing software requirements negotiation process models. The study also describes the issues and limitations in the software requirements negotiations process models.

5 Awakening in Nigerian Democracy: The Change of Government in 2015 General Election

Authors: Nura Suleiman

Abstract:

The democratic dispensation in Nigeria witnessed allot of changes since its beginning up to the 2015 election. The issues of zoning formula, rigging, money politics, god fatherism, and political thuggery among the youths became the centre stage from 1999-2014. But 2015 came with new tune that brings about a little shift from the traditional politics mentioned above, the political socialisation and knowledge penetrated into the sense of electorate where people suddenly change and look for the better option. The paper will examine the democratic change in relation to the 2015 General election which brings General MohammaduBuhari on the mantle of leadership of Nigeria. Many reasons were attributed to the sudden change of government in Nigeria, but the major ones are lack of good governance, corruption, insecurity, political parties’ merger to formed APCand change in INEC leadership. Others are weakness of the leadership and undemocratic nature of PDP government at different level in the country. The glamor for change became necessary because People become more informs about the manifestation of good hope and better Nigeria from the major opposition party (APC). During 2015 election the electorate voted the incumbent government out and replaced it with their choice.

4 Craft Development in the 19th Century Sokoto City: A Lesson towards Economic Diversification in the 21st Century Nigeria

Authors: Nura Bello

Abstract:

Sokoto caliphate is the product of a hectic revolutionary movement that took place in the first decade of the nineteenth century under the leadership of Seikh Usmanu Danfodio. The movement led to the overthrow of the Sarauta system in Hausa Land, leading to the emergence of the Sokoto caliphate and Sokoto city as its headquarters. This development led to the collapse of Alkalawa (headquarters of the Gobir Kingdom) in 1808. A year later, in 1809, Sokoto city emerged as the headquarter of the Sokoto Caliphate. Due to the open door policy adopted by the leaders, the city came to experience an influx of people especially craft manufacturers from all over Hausa Land and beyond, who occupied many areas of the city and engaged in different craft production. This paper aims to highlight the development of crafts manufacturing in the 19th century Sokoto city and its contribution to transforming the city into a major economic base of the caliphate. In dealing with the above issue, qualitative research methods that mainly involve the use of oral and archival data will be adopted. Finally, the paper identified that the expansion of craft manufacturing in the 19th century Sokoto city could have resulted from the role played by the leadership of the caliphate, which favoured such development. The paper argues that if those industries were revived in Nigeria today, they would ultimately create various jobs among the younger generations, which would result in economic prosperity.

3 Notions of Social Justice and Educational Globalization: Evaluations of Israeli Teachers and Students across Sectors

Authors: Clara Sabbagh, Nura Resh

Abstract:

The study delves into students’ and teachers’ notions of social justice (social justice judgments or SJJ), examining how they are shaped by both educational globalization and local (nation-state) conditions. Using the Israeli school setting as a case study, we discuss the status of hegemonic Zionism and two influential perspectives of educational globalization – world culture and the post-colonial critique of neo-liberalism – and derive competing hypotheses about the notions of social justice embedded in them. Against this background, we investigate how SJJ are affected by generation – Israeli teachers and students – and by educational sectors that mirror the society’s major divide: Jewish and Israeli Arab. In order to examine these issues, we used a representative sample of 2000 Israeli students, as well as a sample of 800 social studies teachers. We applied MANOVA repeated-measure for examining to what extent SSJ are dependent upon the type of resource that is distributed (repeated measures) and generational (teachers vs students) and sectorial (Jewish vs. Arab) group variables. As expected, findings revealed that the local context does matter. In other words, rather than being consistent with any of the three perspectives above, findings suggest that respondents elaborate the intersection between global and local traditions by creating various forms of mingled notions of social justice. In other words, Israeli (Jewish and Arab) teachers and students can be conceived as agents who play an important role in recreating national heritages and who differently interpret the ways educational globalization impacts their lives.

2 Effect of Antioxidant-Rich Nutraceutical on Serum Glucose, Lipid Profile and Oxidative Stress Markers of Salt-Induced Metabolic Syndrome in Rats

Authors: Nura Lawal, Lawal Suleiman Bilbis, Rabiu Aliyu Umar, Anas A. Sabir

Abstract:

Metabolic syndrome (MS) a high-risk condition involving obesity, dyslipidemia, hypertension, and diabetes mellitus is prevalent in Nigeria. The study aims to formulate an antioxidant-rich nutraceutical from locally available foodstuff (onion, garlic, ginger, tomato, lemon, palm oil, watermelon seeds) and investigate their effects on blood pressure, body weight, serum glucose, lipid profile, insulin and oxidative stress markers in salt-induced rats. The rats were placed on 8% salt diet for 6 weeks and then supplementation and treatment with nutraceutical and nifedipine in the presence of salt diet for additional 4 weeks. Feeding rats with salt diet for 6 weeks increased blood pressure and body weight of the salt-loaded rats relative to control. Significant (P < 0.001) increase in serum blood glucose and lipid profile, and the decrease in high-density lipoprotein-cholesterol (HDL-C) was observed in salt-loaded rats as compared with control. Both supplementation and treatment (nifedipine) lowered the blood pressure but the only supplementation lowered the body weight. Supplementation with nutraceutical resulted in significant (P < 0.001) decrease in the serum blood glucose, lipid profile, malonyldialdehyde (MDA), insulin levels, insulin resistance, and increased HDL-C and antioxidant indices. The percentage protection against atherogenesis was 76.5±2.13%. There is strong positive correlation between blood pressure, body weight and serum blood glucose, lipid profile, markers of oxidative stress and strong negative correlation with HDL-C and antioxidant status. The results suggest that the nutraceuticals are useful in reversing most of the component of metabolic syndrome and might be beneficial in the treatment of patients with metabolic syndrome.

1 Genetic Diversity of Exon-20 of the IIS6 of the Voltage Gated Sodium Channel Gene from Pyrethroid Resistant Anopheles Mosquitoes in Sudan Savannah Region of Jigawa State

Authors: Asma'u Mahe, Abdullahi A. Imam, Adamu J. Alhassan, Nasiru Abdullahi, Sadiya A. Bichi, Nura Lawal, Kamaluddeen Babagana

Abstract:

Malaria is a disease with global health significance. It is caused by parasites and transmitted by Anopheles mosquitoes. Increase in insecticide resistance threatens the disease vector control. The strength of selection pressure acting on a mosquito population in relation to insecticide resistance can be assess by determining the genetic diversity of a fragment spanning exon- 20 of IIS6 of the voltage gated sodium channel (VGSC). Larval samples reared to adulthood were identified and kdr (knock down resistance) profile was determined. The DNA sequences were used to assess the patterns of genetic differentiation by determining the levels of genetic variability between the Anopheles mosquitoes. Genetic differentiation of the Anopheles mosquitoes based on a portion of the voltage gated sodium channel gene was obtained. Polymorphisms were detected; sequence variation and analysis were presented as a phylogenetic tree. Phylogenetic tree of VGSC haplotypes was constructed for samples of the Anopheles mosquitoes using the maximum likelihood method in MEGA 6.0 software. DNA sequences were edited using BioEdit sequence editor. The edited sequences were aligned with reference sequence (Kisumu strain). Analyses were performed as contained in dnaSP 5.10. Results of genetic parameters of polymorphism and haplotype reconstruction were presented in count. Twenty sequences were used for the analysis. Regions selected were 1- 576, invariable (monomorphic) sites were 460 while variable (polymorphic) sites were 5 giving the number of total mutations observed in this study. Mutations obtained from the study were at codon 105: TTC- Phenylalanine replaces TCC- Serine, codon 513: TAG- Termination replaces TTG- Leucine, codon 153, 300 and 553 mutations were non-synonymous. From the constructed phylogenetic tree, some groups were shown to be closer with Exon20Gambiae Kisumu (Reference strain) having some genetic distance, while 5-Exon20Gambiae-F I13.ab1, 18-Exon20Gambiae-F C17.ab1, and 2-Exon20Gambiae-F C13.ab1 clustered together genetically differentiated away from others. Mutations observed in this study can be attributed to the high insecticide resistance profile recorded in the study areas. Haplotype networks of pattern of genetic variability and polymorphism for the fragment of the VGSC sequences of sampled Anopheles mosquitoes revealed low haplotypes for the present study. Haplotypes are set of closely linked DNA variation on X-chromosome. Haplotypes were scaled accordingly to reflect their respective frequencies. Low haplotype number, four VGSC-1014F haplotypes were observed in this study. A positive association was previously established between low haplotype number of VGSC diversity and pyrethroid resistance through kdr mechanism. Significant values at (P < 0.05) of Tajima D and Fu and Li D’ were observed for some of the results indicating possible signature of positive selection on the fragment of VGSC in the study. This is the first report of VGSC-1014F in the study site. Based on the results, the mutation was present in low frequencies. However, the roles played by the observed mutations need further investigation. Mutations, environmental factors among others can affect genetic diversity. The study area has recorded increase in insecticide resistance that can affect vector control in the area. This finding might affect the efforts made against malaria. Sequences were deposited in GenBank for Accession Number.
