Capital Market as a Barometer for Development: Its Impact and Contribution to Nigerian Economy 1991-2011

This focuses on the influence of Nigerian capital market in economic development of Nigerian. One hypothesis was formulated to guide the study. The dependent variable in this hypothesis was economic development measure by gross domestic product (GPD) while the independent variables include: market capitalization (MKTCAP), total new issues (TNI), number of listed securities (NLS), number of quoted companies (NQC), value of transaction (VT), and turnover Ratios TR. The ordinary least square (OLS) technique was employed to estimate co-efficient of the variables of the multiple regression models based on the time series data collected from the Nigerian stock Exchange, Securities and Exchange Commission, Central Bank of Nigeria and federal office of statistics. The findings reveal a significantly relationship between dependent variable (economic development) and independent variables such as, total new issues and number of quoted companies, whereas market capitalization number of listed securities, value of transactions and turnover ratios showed wrong signs. It was therefore recommended that government should put more effort in developing active issues and motivating local and foreign companies and individual investors to patronize the market by way of raising funds for investment and productive purposes

Multiple Brain Abscesses In A Child With Infective Endocarditis

Background: Infective endocarditis is a lethal infection affecting the endocardium of the heart and the valves.The causes are varied with staphylococcus aureus and streptococcus as the major causative agents.The triad of fever exceeding 38oc,vegetation in the heart and blood culture of the causative agents are the hallmarks of the diagnosis .The disease is known to be affect all ages with the very young age group, those with congenital heart disease and those on cardiac prosthesis as the most vulnerable. Septic emboli from the septic vegetation can spread to the brain, kidney, spleen, and lungs resulting in massive metastatic infections.It therefore has multisystemic manifestations and complications. Though neurological complications are common, brain abcess is known to be rare constituting only 1.0% of neurological complications. Objective: The study aimed at reporting occurrence of both cerebral and cerebellar micro- and macro-abscesses in a 3 year boy with infective endocarditis; a rare occurrence in the literature. Methods: This case report was carried out at University College Hospital Ibadan. Results: The boy presented with fever of 38oc for five weeks, convulsions and altered state of consciousness for ten days..In course of treatment patient however developed irritability and aggressive behaviour, which attracted the use of largactil to which he reacted with extrapyramidal signs and convulsions. Within the week he developed yellowness of the eyes and increase in abdominal girth. Patient had cranial computed tomography (CT) after plain skull X-rays and was referred to University College Hospital Ibadan as a result of the radiologically diagnosed brain abscess seen on CT images. child had grunting respiration with dyspnea, and the respiratory rate was 50/mm. However, the chest was clinically clear. In the cardiovascular system (CVS); the pulse was 140/mm, with moderate volume. The blood pressure (BP) was l60/110 mmHg. The first and second heart sounds were heard with a gallop rhythm. Cranial CT scan showed multiple ring enhancing hypodense lesions with surrounding hypodensity measuring 1cm in diameter and above with only a few measuring less than 1.0cm in both cerebral hemispheres and cerebelli in keeping with multiple cerebral and cerebellar abscesses. An echocardiography showed a brightly echogenic spot attached to the papillary muscle in the left ventricle suggesting vegetation consistent with an infective endocarditis. Retroviral test was negative for both type I and II.Blood culture — was negative, however urine culture yielded klebsiella sp. Serum urea, creatinine, Ca2+ and P04 were all elevated.The abdominal ultrasound scan confirmed the hepatosplenomegaly with decreased echogenicity but both kidneys appeared normal.There was no demonstrable ascitis. The boy was placed on antimicrobials; and had craniotomy for the drainage of the macroabscesses. He improved significantly. His renal and cardiac condition equally improved; he was subsequently discharged to continue treatment in the the paediaric outpatient. The infective endorcarditis still poses enormous challenge in management and the condition calls for multi disciplinary approach. It requires high index of suspicion for early detection; as well deployment of multiple imaging modalities by the cardiologists and radiologists to arrive at a more accurate diagnosis for effective patient management. This may save financial and material resources on part of the patients, care givers, the facility managers and the society at large

Curriculum Management and Graduate Programmes’ Viability: The Mediation of Institutional Effectiveness Using PLS-SEM Approach

This study used a partial least squares structural equation modelling (PLS-SEM) to estimate curriculum management's direct and indirect effects on university graduate programmes' viability. The study also examined the role of institutional effectiveness in mediating the nexus between the predictor and response variables. This is a correlational study with a factorial research design. The study's participants comprised 149 higher education administrators (23 Faculty Deans and 126 HODs) from two public universities in Nigeria. A structured questionnaire designed by the researchers was used for data collection. The questionnaire was duly validated with an acceptable scale and item content validity indices. The dimensionality of the instrument was determined using exploratory factor analysis (EFA). Convergent validity was based on Average Variance Extracted (AVE), whereas discriminant validity was based on Fornell-Lacker criteria and the Hetero-Trait Mono-Trait (HTMT) ratio. Acceptable composite reliability estimates of internal consistency were reached for the three sub-scales. Following ethical practices, the questionnaire was physically administered to respondents and retrieved afterwards. Smart PLS (version 3.2.9) and SPSS (version 26.0) programs were used for all the statistical analyses. This study uncovered significant direct and indirect effects of curriculum management on the viability of graduate programmes. Institutional effectiveness significantly impacted graduate programmes’ viability while mediating the nexus between curriculum management and graduate programmes’ viability. Curriculum management and institutional effectiveness jointly explained a significant proportion of graduate programmes’ viability variance. The result of this study proved that graduate programmes’ viability depends, to a great extent, on how much curriculum is managed and how effective institutions are with their services. The result of this study can enable institutions seeking to run viable graduate programmes to re-evaluate their curriculum management practices and the effectiveness of their services

Lumbosacral Transitional Vertebrae: Association with Low Back Pain

PURPOSE: To assess the prevalence and degree of lumbosacral transitional vertebrae (LSTV) in the Osteoarthritis Initiative (OAI) cohort, to assess whether LSTV correlates with low back pain (LBP) and buttock pain, and to assess the reproducibility of grading LSTV. MATERIALS & METHODS: Institutional review board approval was obtained, and informed consent documentation was approved for the study protocol. Standard standing pelvic radiographs that included the transverse processes of L5 were graded according to Castellvi classification of LSTV in 4636 participants (1992 men and 2804 women; aged 45–80 years) from the OAI cohort. These data were correlated with prevalence and severity of LBP and buttock pain. RESULTS: Prevalence of LSTV was 18.1% (841 of 4636), with a higher rate in men than in women (28.1% vs 11.1%, respectively; P < .001). Of the 841 individuals with LSTV, 41.72% were type I (dysplastic enlarged transverse process), 41.4% were type II (pseudoarticulation), 11.5% were type III (fusion), and 5.2% were type IV (one transverse process fused and one with pseudoarticulation). Of the participants without LSTV, 53.9% reported LBP, while the prevalence of LBP for types I, II, III, and IV was 46%, 73%, 40%, and 66%, respectively (P < .05, χ(2) test). Types II and IV had higher prevalence and severity of LBP and buttock pain (P < .001). CONCLUSION: LSTV types II and IV positively correlate with prevalence and severity of LBP and buttock pain. © RSNA, 201

Characterization of RyDEN (C19orf66) as an Interferon-Stimulated Cellular Inhibitor against Dengue Virus Replication

<div><p>Dengue virus (DENV) is one of the most important arthropod-borne pathogens that cause life-threatening diseases in humans. However, no vaccine or specific antiviral is available for dengue. As seen in other RNA viruses, the innate immune system plays a key role in controlling DENV infection and disease outcome. Although the interferon (IFN) response, which is central to host protective immunity, has been reported to limit DENV replication, the molecular details of how DENV infection is modulated by IFN treatment are elusive. In this study, by employing a gain-of-function screen using a type I IFN-treated cell-derived cDNA library, we identified a previously uncharacterized gene, <i>C19orf66</i>, as an IFN-stimulated gene (ISG) that inhibits DENV replication, which we named <u>R</u>epressor of <u>y</u>ield of <u>DEN</u>V (RyDEN). Overexpression and gene knockdown experiments revealed that expression of RyDEN confers resistance to all serotypes of DENV in human cells. RyDEN expression also limited the replication of hepatitis C virus, Kunjin virus, Chikungunya virus, herpes simplex virus type 1, and human adenovirus. Importantly, RyDEN was considered to be a crucial effector molecule in the IFN-mediated anti-DENV response. When affinity purification-mass spectrometry analysis was performed, RyDEN was revealed to form a complex with cellular mRNA-binding proteins, poly(A)-binding protein cytoplasmic 1 (PABPC1), and La motif-related protein 1 (LARP1). Interestingly, PABPC1 and LARP1 were found to be positive modulators of DENV replication. Since RyDEN influenced intracellular events on DENV replication and, suppression of protein synthesis from DENV-based reporter construct RNA was also observed in RyDEN-expressing cells, our data suggest that RyDEN is likely to interfere with the translation of DENV via interaction with viral RNA and cellular mRNA-binding proteins, resulting in the inhibition of virus replication in infected cells.</p></div
