S. O. Okeniyi,J. A. Kolawole
Research Journal of Pharmacology , 2013,
Abstract: Zobo, a local Nigerian drink suddenly became a household and commercial drink for all classes of people within the past two years, without recourse to possible health implication. A quantitative mineral element content of the water extract of the calyx (Zobo) was carried out. The two major varieties of Hibiscus sabdariffa var rubber-light red calyx (sample 1), and var sabdariffa dark red calyx (sample 11), found in Nigeria, were used for the analysis, using AAS, flame emission spectroscoipy and classical titrimetric methods for the determination of the minerals. Mineral ions assayed are Potassium (K), Sodium (Na), Calcium (Ca), Magnesium (Mg), Zinc (Zn), Iron (Fe), Manganese (Mn), Cadmium (Cd), Lead (Pb), Bicarnonate (HCO) and Chloride (Cl-).The mineral element content of the drink was found to be K, 324.52 400.19mg/L; Na 2.58-8.52mg/L; Ca,140.09 164.01mg/L; Mg 37.52.52-69mg/L; Mn 2.4-11.6mg/L; Fe,0.44-4.58mg/L; Zn, 0.39-0.9mg/L; Pb, 0.00-0.73mg/L; Cd, 0.00-0.05mg/L and anions, C1-, 0.001 0.9mg/L and HCO-, 6.67.0mg/L. The extract from sample 11 on the average has a higher mineral element content, than sample 1, however the difference were not statistically significant (P>0.05). The claimed diuretic and antihypertensive effects of the drink might be linked with the high level of K and low level of Na and Cl-

South African Medical Journal , 2012,
Abstract: Background. Severe anaemia (haemoglobin concentration <50 g/l) is a major cause of paediatric hospital admissions and deaths in the tropics. Objectives.To examine the pattern and predictors of mortality among severely anaemic children. Methods. A prospective cross-sectional study was conducted among children with severe anaemia at the Children’s Emergency Room of the University Teaching Hospital, Ado-Ekiti, Nigeria. Sociodemographic characteristics, clinical features, laboratory findings and co-morbidities of the survivors and those who died were compared by logistic regression analysis. Results. Of the 1 735 children admitted, 311 (17.9%) had severe anaemia, with a case-fatality rate of 9.3%. The presence of respiratory distress (95% confidence interval (CI) 2.1 - 3.6, p=0.031); acidosis (95% CI 1.8 - 2.7, p=0.010); coma (95% CI 0.1 - 0.3, p=0.001); hypotension (95% CI 2.0 - 4.2, p=0.020); and bacteraemia (95% CI 3.1 - 3.9; p=0.008) were the significant independent predictors of death with regression analysis. Conclusion. Early recognition with prompt and appropriate anticipatory intervention is essential to reduce mortality from severe anaemia.

The Cardiology , 2011, DOI: 10.3923/tcard.2010.18.22
Abstract: Heart failure is an important cause of morbidity and mortality among children. There are very few reports on heart failure among the children living in developing countries. This informed the decision to study heart failure among the children at the hospital. The objectives of this study were to determine how common heart failure is its aetiologies and contribution to morbidity and mortality in childhood. The study was prospective in design and was carried out on consecutive children presenting with heart failure between 1st of April and the 30th of September 2007 at the paediatric emergency unit of Ladoke Akintola University of Technology Teaching Hospital, Osogbo, Nigeria. A total 391 children presented at the paediatric emergency in this 6 months period. Of the 391 subjects, 35 (9.0%) presented with heart failure. The 35 children consisted of 21 boys and 14 girls giving a male to female ratio of 1.5:1. The age range of the children studied was between 1 month and 13 years and the mean age was 3.1±3.5 years. Total 13 (37.1%) children were in the age range 1 month to 1 year while 15 (42.7%) were aged between >1-5 years and 7 were aged >5-12 years. Anaemia, bronchopneumonia, lobar pneumonia, ventricular septal defect, transposition of the great arteries, acute glomerulonephritis, rheumatic fever, myocarditis and septicemia were identified as causes in 57.1, 28.6, 8.6, 2.9, 2.9, 2.9 and 2.9% of cases, respectively. Most cases of aneamic heart failure were due to malaria. Of the 28 children aged below 5 years, pneumonia and malaria induced aneamia was responsible for CCF in 26 (92.9%) compared with the equivalent 3 (42.9%) amongst the total 7 subjects aged over 5 years. This difference is statistically significant. p = 5.52, χ2 = 0.02, Yate s correction applied. The average number of hospitalization days was 3.2 and 6.2 for patients with heart failure secondary to anaemia and pneumonia, respectively. Of the 35 children studied 29 (82.9%) had good recovery, 3 (8.6%) died, 2 (5.7%) were discharged against medical advice and one (2.9%) was referred to the university college hospital for further management.

Research Journal of Applied Sciences , 2012,
Abstract: A modified Clevenger hyrodistillation apparatus was used to obtain essential oils from the leaf, stem bark and root of Vitellaria Paradoxa plant. Thin Layer Chromatographic (TLC) analysis of the oils in 1:1 and 3:1 hexane-ethyl acetate solvent mixtures gave Retention Index (RI) values indicative to the likely presence of geraniol, -pinene, D-carvone, L-carvone, Eugenol and citral. Antimicrobial and antifungal screening of the oils using a good number of pathogenic microorganism at 50-300 mg mL 1 concentrations indicated high activity on a large number of bacteria and fungi.

Journal of Environmental Science and Technology , 2012,
Abstract: Reclaimable energy generated from waste is a major source of environmentally sustainable energy that is not yet explored in Nigeria. This study therefore, investigated the energy recoverable potential from waste, using waste materials generated in a model community in Nigeria. For the model community of the country, Covenant University, Ota, Nigeria was used, because of its existing form of waste management system. Solid waste generated in this model community was characterised into its separate components and this was then subjected to an estimation model by which the recoverable energy potential from the waste was evaluated. For this, method of waste to energy calorific value evaluations were employed for predicting equivalent energy availability from the waste in kWh and in equivalent tonnes of oil. Results obtained from the study show abounding viability of favourable energy potential that could be as high as 8967.13 MJ day-1, equivalent to 2490.87 kWh day-1 or 0.6227 tonnes of oil equivalent per day. These findings bare suggestions of the need for the development of waste management system infused with energy reclamation policy, from waste, for supplementing communal energy needs and annexing other social benefits accruable from such policy implementation.

Agricultural Journal , 2013,
Abstract: Comparative analysis of the acetylene induced ripened and naturally ripened mango and banana fruits were studied. The Kinetic studies on the rate of decrease in total acidity were also investigated. The vitamin C contents of induced mango and banana fruits were 25.50 and 25.09 mg 100g 1, respectively while naturally ripened mango and banana fruits were 24.53 and 24.40 mg 100g 1. The total percentage sugar in induced mango and banana fruits were 22.06 and 21.06%, while naturally ripened mango and banana were 21.06 and 20.63%, respectively. The vitamin C (ascorbic acid) content and total percentage sugar data were higher than the naturally ripened fruits. The Kinetic studies of the rate of decrease of the total acidity gave a first order rate constant (K) for mango and banana juice as 1.5 10-2h-1 and 1.2+10-2h-1, respectively while the t1/2 ranged 57.75-46.20 and 69.30-57.75 h for the induced mango and banana fruits. There was a sharp decrease in the total acidity of the induced fruits against the naturally ripened ones.
Effect of Mechanism of Chloride Ion Attack on Portland Cement Concrete and the Structural Steel Reinforcement
U.A. Birnin-Yauri,Saidu Garba,S.O. Okeniyi
Research Journal of Applied Sciences , 2012,
Abstract: The effect and mechanism of chloride ion concentration of portland cement concrete and the structural steel reinforcement was investigated. At low concentrations, chloride ion has little or no effect on the physical stability of concrete structure but it causes the corrosion of the re-enforcing steel in the concrete but at high concentration and especially at low temperature, it causes expansion and cracking in the concrete. The degradation is usually accompanied by formation of calcium oxychloride salts. The mechanism for this destruction was discovered in this work as a result of the thermal transformations of the calcium oxychloride salts: 3CaO.CaCl2.15H2O to CaO.CaCl2. 2H2O.
