Universal Electronic Student Course Registration Model (U-ESCRM)

Student course registration is an integral facet of university registration processes, which holistically cater for organizational resources: manpower and material. Although several approaches have been proposed in addressing student registration, this research paper provide a comprehensive approach with the aim of addressing comprehensiveness in courses registration through the integration of departmental units within the university into a single architecture framework. This architecture has the propensity in supporting organizational procedures and processes while lessening overhead costs associated with process depletions

A Review of Environmental Implications of Dredging Activities

Dredging is a global anthropogenic excavation activity of removing sediments from water bodies and depositing it elsewhere. It is a mixed blessing as it has both beneficial and adverse impacts. This paper is on a review of environmental implications of dredging. The objective of the paper is to review previous works by researchers on the environmental consequences of dredging. The method used is a review of academic/journal articles, internet materials, conference / workshop papers, textbooks, bulletins and publicly available materials on dredging activities. The results of the study revealed that previous authors whose works were reviewed have a convergent view that apart from the beneficial impacts of dredging (e.g. keeping waterways navigable, flood and storm protection and provision of materials for road construction and building), it has lots of adverse environmental impacts, including environmental pollution, erosion, widespread hydrological changes, reduction in the population of aquatic lives like destruction of fish spawning grounds and benthic organisms and resuspension of particulate matter column that has elevated levels of lead, copper, zinc and nickel in Phytoplankton. Recommendations of the study include: (1) establishment of environmental legislations and regulations for dredging operation; (2) use of green technology in dredging activities to minimize suspension of sediments and contamination/pollution of dredging environments; and (3) creation of awareness among dredging contractors, regulators and marine communities where dredging take place on the economic and ecological values of the marine ecosystems that are usually very sensitive, fragile and productive

Biocidal effects of dennettia tripetala, zingiber officinale and benlate on seedborne fungal pathogen (fusarium moniliforme) of watermelon (citrullus lanatus) varieties.

This study was carried out to investigate the effect of plant extracts, African pepper fruit (Dennettia tripetala) and Ginger (Zingiber officinale) on seed borne fungal pathogens of Watermelon (Citrullus lanatas) seeds. Watermelon seeds were extracted for seed health test using blotter paper method. The antifungal effects of ethanol and acetone extracts of the two plant extracts and synthetic fungicide were studied under in- vitro experiment against the seed borne fungal pathogen of Watermelon at 0%, 50% and 75%. It was a 3x3 factorial experiment at 5% Probability level laid out in a Completely Randomized Design experiment with three replications Ninety percent germination was obtained in the germination and seed health test of Watermelon seeds. Seed borne fungal pathogen (Aspergillus spp. and Fusarium spp.) were identified. The potential of these organisms for pathogenicity were tested using Kock’s postulate. The result of the pathogenicity test showed that Fusarium spp. was pathogenic. All plant extracts and Benlate inhibited the fungus (Fusarium moniliforme) in culture. The inhibition was also greater as concentration increased from 50% to 75%.  It was also observed that ethanol extraction solvent did better than acetone. Generally, Dennettia tripetala extract performed better than Zingiber officinale. It could therefore be recommended that the two plant extracts used in this investigation which were very effective in the control of Fusarium moniliforme of watermelon could be an alternative to the synthetic fungicide. It could also be suggested that further studies be carried out to isolate, identify, characterize and standardize the bioactive components of these phytochemicals in a bid to commercializing their production

Studies on the Lipid Profiles of Wistar Rat Models Treated with Aqueous and Methanolic Leaf Extracts of Alchornea Cordifolia and Thaumatococcus Daniellii

This study aims at establishing the effect of T. daniellii and A. cordifolia leaf extracts on the lipid profile of experimental rat models. A total of twenty five (25) adult male wistar rats were used for the study. The rats were divided into five groups of five rats each. Group I (normal control) was administered with 2ml/kg distilled water p.o. Group II was administered with 200mg/kg aqueous leaf extract of T. daniellii p.o. Group III was administered with 200mg/kg methanolic leaf extract of T. daniellii p.o. Group IV and V were administered with 200mg/kg aqueous and methanolic leaf extracts of A. cordifolia respectively. Administration of extracts lasted for 14 days after which animals were sacrificed and serum developed from blood samples was collected and used for analysis to evaluate the lipid profiles of experimental models using standard methods. Results obtained from the study show that the highest level of Low Density Lippoprotein (LDL) (31.21±0.04 mg/dL) was recorded on Group II and was not significantly different from the control group (33.20±0.10 mg/dL). However, for High Density Lipoprotein (HDL), the highest level was recorded on Group IV (48.14±0.08mg/dL). Similarly, this was not significantly different from the Control group (51.80±0.10mg/dL). Group II presented the highest level of Triacylglyceride (TG) (48.80±0.02mg/dL), which however, was considered not significantly different from the control group (51.17±0.08mg/dL). For Total Cholesterol (TC), highest level (64.64±0.49mg/dL) was recorded on Group II and value was not significantly different from that recorded on the normal control (63.83±0.10mg/dL). In conclusion, it can be deduced from this study that extracts of T. daniellii and A. cordifolia lacks the potential to alter the lipid profile of patients depending on them for one medicinal use or the other and may thus be considered potential candidates for drug development

Assessment of health communication practice on hepatitis B in Southwest Nigeria

In line with the Sustainable Development Goal 3:3 of ending the epidemic of hepatitis by year 2030, there is a global call for strategic information to understand viral hepatitis. Existing studies on hepatitis B virus (HBV) in Nigeria have primarily focused on health practitioners and their patients, to the neglect of detailed empirical data on health communication practice, especially as it relates to semi-urban and urban demographic information. The study set to find out the communication strategies employed by government and non-government organisations working on HBV, as well as the preferred health communication channels for hepatitis B by semi-urban and urban residents. The study adopted a mixed method. The qualitative method assessed the communication strategies employed by government and non-government health-related agencies in informing people on HBV in Nigeria while, the survey examined the preferred health communication channels for HBV management among 582 semi-urban and urban residents in Lagos, Oyo, and Ogun States, Southwest Nigeria. Bivariate analyses were performed on demographic variables and preferred health communication channels for HBV by states. This study found that government agencies and non-government organisations working on hepatitis B predominantly make use of interpersonal communication in getting the people informed of HBV. Also, residents of Southwest Nigeria (elderly, 71.4% (Lagos), married couples, 53.7% (Ogun)) preferred the internet as a health communication source for hepatitis B information as against traditional means of television, radio and print platforms

Outcomes in randomised controlled trials in prevention and management of carious lesions:a systematic review

Abstract Background Inconsistent outcome reporting is one significant hurdle to combining results from trials into systematic reviews. Core outcome sets (COS) can reduce this barrier. The aim of this review was to map outcomes reported in caries prevention and management randomised controlled trials (RCT) as a first step to COS development. We also investigated RCT characteristics and reporting of primary outcomes and sample size calculations. Methods PubMed, Embase, Web of Knowledge and Cochrane CENTRAL were systematically searched (1 January 1968 to 25 August 2015). Inclusion criteria: RCTs comparing any technique for prevention or management of caries with another or placebo and RCTs comparing interventions to support patients undergoing treatment of caries (without setting, dentition or age restrictions). Categories were developed through piloting and group consensus and outcomes grouped accordingly. Results Of 4773 search results, 764 were potentially relevant, full text was available for 731 papers and 605 publications met the inclusion criteria and were included. For all outcomes across the time periods 1968–1980 and 2001–2010, reporting of outcome ‘caries experience’ reduced from 39% to 18%; ‘clinical performance of the restoration’ reporting increased from 33% to 42% although there was a reduction to 22% in 2011–2015. Emerging outcome domains include ‘lesion activity’ and ‘pulp health-related outcomes’, accounting for 1% and 0%, respectively, during 1968–1980 and 10% and 4% for 2011–2015. Reporting ‘resource efficiency’ and ‘quality of life measures’ have remained at a low level. No publications reported tooth survival independent of an index such as DMFT or equivalent. Primary outcomes were only identified as such in 414 (68%) of the reports. Conclusions Over the past 50 years, outcome reporting for trials on prevention and management of carious lesions have tended to focus on outcomes measuring caries experience and restoration material clinical performance with lesion activity and cost-effectiveness increasingly being reported. Patient-reported and patient-focused outcomes are becoming more common (although as secondary outcomes) but remain low in use. The challenge with developing a COS will be balancing commonly previously reported outcomes against those more relevant for the future. Trial registration PROSPERO, CRD42015025310 .

However, the assessment of the fibrinolytic systemis not yet accepted into routine clinical practice.In this review, we will revisit the different methods of assessing endogenous fibrinolysis (factorial assays, turbidimetric lysis assays, viscoelastic and the global thrombosis tests), including the strengths, limitations, correlation to clinical outcomes of each method and howwe might integrate the assessment of endogenous fibrinolysis into clinical practice in the future.Peer reviewedFinal Published versio

Secretome of mesenchymal stem cells and its impact on Chronic Obstructive Pulmonary Disease

Chronic obstructive pulmonary disease (COPD) is characterized by irreversible loss of lung function that stem from two mechanisms, inflammation and senescence. Crosstalk between these two mechanisms accelerate the development of COPD, thus targeting these two pathways may offer benefits in the treatment of COPD. Growing amount of evidence have shown that mesenchymal stem cells as a promising candidate for the treatment of COPD. Over the years, many studies conducted to decipher the therapeutic effect of MSC in COPD and the mechanisms involve, in the hope of utilizing these cells as new therapeutic strategy for COPD. However, the cell-based therapy by using the MSC presented with many obstacles including low engraftment at the site of injury, the risk of microvascular occlusion, unwanted differentiation, and also the risk of malignant transformation. Recently, recently researchers begin to look at the possibility of using MSC derived extracellular vesicles as an alternative to MSC. Here we review the effect of MSC and MSC derived EV in modulating inflammation, and senescence in COPD. We also review current treatment and the side effect in COPD, and senolytic drugs, a new therapeutic strategy targeting the senescent cells

Framework for Developing Web (Text-Based) Teleconferencing System.

The use of Internet and other high performance computing technologies are common among people around the globe. We develop a Web (text-based) Teleconferencing System (WTS) that is built using open standards with the vision to meet different scalability and security needs for conducting text-based conferencing among different people in different locations around the world. This system provides teleconferencing features which include support for hosting open and closed-type multiple conferences simultaneously as well as support administrative features like creating/deletion of conference rooms, creating/deletion of users and moderation of users. The research methodology used in this research is object-oriented. The platform of this system is J2EE (Java 2 Enterprise Edition) and it adopts four-tier architecture. We employ MVC (Model-View-Controller) framework to structure the problem-domain classes into model, view, controller components. The MVC framework is implemented using J2EE APIs (Java 2 Enterprise Edition Application Programming Interfaces)-Servlets for Controller, JSP (JavaServer Pages) and Servlets for View, and JavaBeans for Model. The functionality of this system is flexible and reliable
