- Diclofenac (DIC) is known to alter renal function in the form of hemodynamically-mediated acute renal failure. This study evaluated the protective role of the amino acid, glycine (Gly) on nephrotoxicity and acute hemodynamic alterations induced by DIC (9 mg/kg) in male Wistar rats. The rats were divided into four groups (n=7/group) including Group A (control); Group B (DIC-treated), Groups C (DIC + Gly1, 250 mg/kg) and Group D (DIC + Gly2 500 mg/kg). Systolic (SBP), diastolic (DBP) and mean arterial (MAP) blood pressures were significantly (p<0.05) reduced in rats treated with DIC alone, compared to control. Kidneys from DIC-treated rats showed altered histology with significantly (p<0.05) increased hydrogen peroxide (H2O2), malondialdehyde (MDA) and protein carbonyl contents, but decreased glutathione (GSH) glutathione peroxidase (GPx), glutathione S-transferase (GST) and superoxide dismutase (SOD) activities. Immunohistochemistry revealed down-regulation of renal angiotensin converting enzyme (ACE), but increased expressions of angiotensin type II receptor (AT2R) and mineralocorticoid receptor (MR) in DIC-treated rats. However, pre-treatment with Gly reversed most of the aforementioned effects of DIC. The present results suggest that oral glycine protected kidney tissues and restored DIC-induced hemodynamic changes by modifying renal expression of the renin-angiotensin-mineralocortocoid pathway and/or renal oxidative stress. 4 results 4

- The impact of oil price shocks on the economy has occupied the attention of researchers for almost four decades. Majority of studies support the existence of a negative association, while some recent evidences seem to have popularised the view that outcomes are the artefacts of misspecified functional forms. This study, although similar in spirit to this popular opinion, is, however, distinct in a number of ways. Firstly, unlike most Nigeria-specific studies, this paper explores alternative measures of oil price shocks, which have been developed and used in the literature with a view to ascertaining the extent to which conclusions about the oil price-growth association depend on the definition of shocks adopted. More importantly, this, to the best of our knowledge, is a pioneer attempt at introducing threshold effects into the linkage between oil price shocks and output growth in Nigeria. The relatively recent regime-dependent multivariate threshold autoregressive model, together with the characteristic impulse response functions and forecast error variance decomposition, is adopted in this study. Using quarterly data spanning 1985–2008, a non-linear model of oil price shocks and economic growth is estimated. Our main results indicate that oil price shocks do not account for a significant proportion of Observed movements in macroeconomic aggregates. This pattern persists despite the introduction of threshold effects. This implied the enclave nature of Nigeria’s oil sector with weak linkages. Therefore, the need to spend oil revenue productively is imperative if favourable effect on real output growth is envisaged. 4 results 4

- Background: Little is known about factors that determine the QoL of elderly persons living in developing societies undergoing rapid social changes. Method: A representative sample of elderly Nigerians, aged 65 years and over (n= 2152), was assessed for QoL using the World Health Organization Quality of Life instrument (WHOQoLBref). Other than sociodemographic factors, respondents were also evaluated for major depressive disorder, physical conditions as well as for social network, support and engagement. Using linear regression modeling, these factors were explored for their ability to predict the physical, psychological, social and environmental domains of QoL. Results:Economic status was the most consistent predictor of the four domains of QoL, with the coefficients ranging between 1.0 and 1.68 (p < 0.001 in every instance). Among health variables, functional disability (range: 7.07 – 19.86) and self-rated overall health (range: 7.89 – 18. 42) were the most salient. Participation in community activities (range 7.74 – 17.48) was the most consistent social predictor. As a group, social factors, especially those relating to social support and participation, were the strongest determinants of QoL. Conclusion: Even though health factors are important, social factors, in particular those relating to the quality of social support and participation, are the most important predictors of QoL. 2 results 2

- Good pedestrian facilities support the ease, comfort and safety of pedestrians. A good pedestrian sidewalk requires a good surface condition with appropriate footpath width and surface quality. This study assessed pavement condition of sidewalks in the University of Ibadan using the Pavement Condition Index (PCI) method. PCI evaluates the surface condition of sidewalks based on distresses observed. The PCI ratings vary from 0 to 100, representing the worst and best surface conditions, respectively. Based on the regular use of sidewalks for access, eighteen major roads were selected within the University of Ibadan. A distress assessment survey was conducted on the roads to collect data on defective sidewalk pavements and their distress conditions. The sidewalks were mainly of two types: plain concrete and concrete slab. Average sidewalk width for fourteen of the roads was less than 1.5 m stipulated in highway design manuals. Sixty percent of the sidewalks were in good condition with PCI values greater than 70. The recurring defects on the plain concrete sidewalk included linear, edge and map cracking. Depression of slab units was the most severe defect on the concrete slap sidewalk. The PCI analysis was used to assess the surface conditions of sidewalks in the University of Ibadan. The results can be used to design maintenance activities to keep the sidewalk system in optimal operational function. Having and updating inventory of the sidewalk system will promote regular routine maintenance and encourage safe use of the system 2 results 2
