Impact of Abandoned Structures on Residents in Ilorin, Kwara State, Nigeria
The increasing incidence of abandoned structures coupled with the associated seemly insurmountable environmental, psychosocial and economic risks in a developing country like Nigeria is a nerve racking problem of concern to the government and the communities. The study therefore, within the context of the three residential densities the study examined the incidence, causes and impacts of abandoned structures with a view to providing information on the extents and effects of abandoned structures on residents in Ilorin. The study utilized primary data obtained with the aid of questionnaire from 428 residents collected in the ratio 3:2:1 in high, medium and low density residential areas. Four indices were developed: ‘Environmental Impact of Abandonment’ (EIAI), ‘Psycho-Social Impact of Abandoned Structures’ (PSIASI), ‘Economic Impact of Abandonment’ (EcIAI) and ‘Suggested Solutions to Abandonment’ (SSA). It is observed that the incidence of abandoned structures varies significantly among the residential neighbourhoods of Ilorin metropolis (F = 9.458 and p = 0.036 at 95% confidence level). The magnitude of the six categories of abandonment in Ilorin metropolis is more in the high density area then in medium and low density. Residents of different residential densities of Ilorin do not have the same or similar views about the environmental effect of abandonment in their areas (F= 4.604 and p= 0.0160. The study recommends as suggested by respondents increase in basic salary (SSA =, 4.31) local planning authority should work on blight control (SSA = 4.29) and there should be proper site selection before commencement of building projects (SSA =.4.28).

Impact of Cement Dust on Physical and Chemical Nutrients Properties of Forest Topsoil
: The study examined the impact of Cement dust on physical and chemical nutrients properties of forest topsoil in close proximity to a major private cement industry in Obajana, Kogi State, Nigeria using standard methods by collecting Topsoil samples for physical and chemical properties analyses which are particle size, moisture content, pH, carbon, nitrogen,phosphorus, potassium, sodium, calcium, magnesium, cation exchange capacity and organic matter.Data revealed a strong influence of the particulate pollutants on the forest topsoil in close proximity to the Cement factory. It was observed that the soil properties; moisture content and soil pH varied at distances away from the factory. The result showed that the Cement dust particles entering the soil increased the pH of the soil, it more alkaline. The highest pH (6.03) was observed from hundred and fifty meters sample indicating the highest particulate pollution. There were also variations in the other soil nutrient properties; carbon, nitrogen, phosphorus, potassium, sodium, calcium, magnesium, cation exchange capacity and organic matter arising from the effect of cement dust. High organic matter content was recorded in the location samples compared with the control sample. This is attributed to the addition of cement dust to the soils, resulting in improved organic-matter cycling and plant growth. The result also showed that the chemical properties; organic carbon (OC), organic matter (OM), phosphorus (P), potassium (K), sodium (Na), calcium (Ca) and magnesium (Mg) are significantly higher in the study areas than the control. The study therefore concludes that the emission of cement dust on the forest stands over the years was found to have significantly affected the topsoil properties
Effect of iodine biofortification on incidence and severity of Fusarium wilt and yield of tomato (Solanum lycopersicum L.)
Tomato is often attacked by wilt caused by Fusarium oxysporium. Iodine is known to have fungistatic effect in pathogen control. The present experiment was aimed at determining the effect of iodine compounds (potassium iodide, KI and potassium iodate, KIO3) on incidence and severity of Fusarium wilt and yield of two tomato accessions, FUNAABTO/106 and FUNAABTO/123. The experiment was conducted in the screenhouse and on the field. KI was applied at concentrations of 1, 2, 3, 5 mM while KIO3 was applied at concentrations of 0.5, 1, 2, 3 mM. The untreated plots served as control. Results showed that FUNAABTO/106 treated with 0.5 mM KIO3 in the screenhouse and on the field had the least (0.00%) disease incidence. Disease severity was significantly (p ≤ 0.05) lower (1.00) in the screenhouse in pots containing FUNAABTO/106 treated with 1 mM KIO3. On the field, FUNAABTO/106 treated with 0.5 mM KIO3 had the least (1.17) disease severity. FUNAABTO/106 treated with 0.5 mM KIO3 in the screenhouse and on the field were significantly higher (1.65t/ha and 18.54t/ha respectively) in yield. The study concluded that application of iodine compounds at lower concentrations reduced the incidence and severity of Fusarium wilt and increased the yield of tomato.Keywords: Potassium iodate (KIO3), Potassium iodide (KI), Fusarium oxysporiu
Changes in mediators of inflammation and pro-thrombosis after 12 months of dietary modification in adults with metabolic syndrome
Objective: This study evaluated the effects of a 12-month dietary modification on indices of inflammation and pro-thrombosis in adults with metabolic syndrome (MS).Materials and methods: This longitudinal study involved 252 adults with MS recruited from the Bodija market, Ibadan and its environs. Participants were placed on 20%, 30% and 50% calories obtained from protein, total fat and carbohydrate respectively and were followed up monthly for 12 months. Anthropometry and blood pressure were measured using standard methods. Fasting plasma glucose (FPG), total cholesterol (TC), triglycerides (TG), high density lipoprotein-cholesterol (HDL-C), fibrinogen, plasminogen activator inhibitor-1 (PAI-1)], interleukin-6 (IL-6) and interleukin-10 (IL-10) were measured using spectrophotometric methods and ELISA as appropriate. Data was analysed using ANCOVA, Student’s t-test, Mann-Whitney U and Wilcoxon signed-rank tests. P-values less than 0.05 were considered significant.Results: After 6 months of dietary modification, there was a significant reduction in waist circumference (WC), while the levels of HDL-C, fibrinogen and PAI-1 were significantly increased when compared with the corresponding baseline values. However, WC and fibrinogen reduced significantly, while HDL-C and IL-10 significantly increased after 12 months of dietary modification as compared with the respective baseline values.Conclusion: Long-term regular dietary modification may be beneficial in ameliorating inflammation and pro-thrombosis in metabolic syndrome.Keywords: Dietary modification, fibrinogen, interleukins, metabolic syndrome, plasminogen activator inhibito
