Phylogenetic and genomic relationships in the genus Malus based on RAPDs
Two separate experiments were carried out between local and exotic apple among the locally available varieties. Ten varieties of local apple ( Malus spp.) were selected from South west Nigeria. The choice of the samples was based on observed morphological differences such as size of fruits, fruits color, flower color, leaf shape and plant height while the choice of imported exotic type was based solely on the color of the fruit. Total genomic DNA was isolated from local and exotic apples separately and assessed with RAPD markers. Nine primers generated a total of forty-six polymorphic bands, which were used to generate a UPGMA dendrogram. The dendrogram consists of a single cluster from 0 – 65% similarity coefficient. At 71%, two clusters were discerned with sample 6 and 7 having separated from the clusters. However, two samples 3 and 4 tied at 87% showing the possibility of very close relationships. Two local apples (green and red color) and one exotic apple (green color) were analyzed with 132 bands from 16 polymorphic primers. The dendrogram generated showed a closer relationships between green exotic and green local varieties of apple
Human Capital Development and Poverty in Nigeria, 1960 - 2009: An Econometric Assessment
This study examined the relationship between human capital development and poverty in Nigeria using data spanning 1960-2009. The human capital development variable was measured using conventional variables i.e. education and health, with government expenditures on education and health being used as the proxies. Other variables on communication, transportation and utility were used as control. A readily available poverty measure, gross domestic product per capita was used to capture poverty status. This is based on the fact that poverty is mostly measured in monetary terms captured by income or consumption per capita or household in the absence of direct primary data observation. After carrying out the diagnostic tests, the cointegration analysis carried out proved that, to some extent, a cointegrating relationship exists between the poverty measure and human capital development indicators. However, the Granger causality estimation results show that both education and health expenditures are fundamental in reducing poverty level based on the uni-directional causality while no causality runs from poverty status to the indicators.

Ethnozoological Study of Wild Bird Species Body Parts Supply in Traditional Medicine Markets, Abeokuta, Nigeria
The paper examined the ethnozoological study of wild bird species' body parts supply of eighty-three traditional medicine marketers in six traditional medicine markets in Abeokuta North and South Local Government Area, Ogun State, Nigeria using snowball and convenience sampling techniques through the administration of a set of structured questionnaire to 83respondents. The result showed that four-fifths of the total respondents were females (85.54%), two-thirds of the total respondents (68.68%) were less than 50 years and 91.56% of the total respondents had formal education. A total of 21 bird species had their body parts and products on sale in the different markets studied in the study area. Due to the belief and faith of the people, the respondents agreed that there were some bird species that are regarded as being sacred or forbidden and thus, the birds and their bird body parts are used and sold in traditional medicine to treat different ailments and for sacrificial activities of their clients. It was concluded that the existence of bird species cannot be over-emphasized because they are important in believed resources for curing specified types of ailments and sacrificial offerings in traditional medicine. It was recommended that since birds significantly contribute to the natural ecosystem, human health and nutrition, forest and wildlife conservation campaign should be strengthened
PERFORMANCE AND CARCASS CHARACTERISTICS OF FINISHING BROILERS FED DIETS SUPPLEMENTED WITH COMBINATION OF PROBIOTICS (B. cereus) AND PREBIOTICS (MANNOSE [MOS])
The experiment aimed to investigate effect of combination of probiotics and prebiotics on the performance and carcass characteristics of broilers at finishing phase. A total number of 300 day-old Anak broiler chicks were used to determine the response of broiler chicks to diets supplemented with probiotics (Bacillus cereus) and prebiotics (Mannose). The chicks were randomly allotted to four treatment groups of 75 birds with 25 birds per replicate in a completely randomized design. The four dietary treatments comprised 500ppm MOS; 250ppm B. cereus + 500ppm MOS; 500ppm B. cereus + 500ppm MOS and 750ppm B. cereus + 500ppm MOS, respectively. Results showed that feed conversion ratio decreased significantly (P< 0.05) from 1.21 for groups fed det supplemented with 250ppm B. cereus + 500ppm MOS to 1.05 for groups fed with 750ppm B. cereus + 500ppm MOS as more prebiotics were added to the probiotics. Final live weight, eviscerated weight and dressing percentage were significantly (p<0.05) influenced by combination of probiotics and prebiotics in finishing broilers. Final live weight values ranged from 2453.30g in birds fed 250ppm B. cereus + 500ppm MOS to 2488.30g in birds fed 750ppm B. cereus + 500ppm MOS, while eviscerated weight ranged from 1063.30g at 500ppm MOS to 1396.70g at 750ppm B. cereus + 500ppm MOS. The same trend was observed for dressing percentage, neck, whole gizzard and liver. It was concluded that combination of probitics and prebiotics at 750ppm B. cereus + 500ppm MOS had positive effect on growth performance and carcass qualities of broilers at finishing phase.

Menstrual-Related Headaches Among a Cohort of African Adolescent Girls
Introduction: Migraine attacks associated with menstruation are generally perceived as more severe than attacks outside this period.
Aim and Objective: The study aimed at determining the frequency of menstrual-related headaches among a cohort of senior secondary school girls in Abeokuta, Nigeria. We also determined its burden among these school girls.
Methodology: This study was cross-sectional using a validated adolescent headache survey questionnaire. A self-administration of the instrument was done during a school visit. A headache was classified using the ICHD-II criteria.
Results: Of the 183 students interviewed, 123(67.2%) had recurrent headaches. Mean age ±SD, 16.18± 1.55 (range 12– 19). The prevalence of definite migraine was 17.5% while the prevalence of probable migraine was 6.0%. The prevalence of tension-type headache was 41.0%. Migraine was significantly menstrual-related (p=0.001, 95% CI=1.06– 6.63). Median pain severity score was higher among MRH group (p=0.043). The median number of days of reduced productivity and missed social activities was significantly higher in the MRH group; p= 0.001 and p=0.03, respectively. Subjects with MRH were more incapacitated by their headaches (p= 0.003).
Conclusion: Menstrually related headache is prevalent even among the adolescent and it has adversely affected their productivity and social life. Care of adolescent with headaches should be intensified
Assessment of Urban Infrastructure Quality and User Satisfaction in Low Income Residential Neighbourhoods in Minna, Nigeria
This study assessed urban infrastructure quality and the level of user satisfaction with urban infrastructure in low income residential neighbourhoods in Minna, Nigeria. Five (5) neighbourhoods were selected for the study, and a total of 250 housing units were sampled. Questionnaire was administered on households that fell within the sample and used to retrieve relevant data. This was followed with an observatory study of the entire study area. Simple descriptive statistic, frequency distribution, Kruskal wallis (H) test, Pearson's correlation, and Relative satisfaction index (RSI) were used to analyse collected data at different levels in the research. Analyse-it ® v4.5 statistical software for Microsoft excel was used to carry out all statistical analysis. Seven (7) components of urban infrastructure were identified to sustain residential properties in the study area and the varied conditions of each of these infrastructure was presented. The overall quality of urban infrastructure was established based on cumulative weighted scores of respondents rating of urban infrastructure quality in their respective neighbourhoods. Total weighted scores of 600 and below signified a general poor quality of urban infrastructure in the affected areas. A correlation coefficient of 0.853 indicates a strong positive relationship between drainage conditions and the condition of access roads, among others, while low RSI for access roads (1.972), drainage systems (1.456), waste disposal (1.712), security (2.632), water supply (1.372), electricity supply (1.52), and neighbourhood cleanliness (1.688) indicate a very low level of user satisfaction with urban infrastructure in the study area. Over 50% of respondents described the management of urban infrastructure in their neighbourhoods as being poor. The study recommend that efforts by the concerned authorities should be intensified towards the provision and proper management of urban infrastructure in urban areas.Keywords: Infrastructure quality, residential neighbourhood, urban infrastructure, usersatisfactio
Bleaching of Palm Oil by Activated Local Bentonite and Kaolin Clay from Afashio, Edo-Nigeria
The bleaching potential of Afashio kaolin (AFK), from Edo state in Nigeria, for removal of pigments from palm oil was investigated in comparison with that of local bentonite (BN). Both AFK and BN were activated by acid treatment. Batch experiments were conducted to study the effects of adsorbent dosage (2 – 8 %), contact time (0 – 1.5 hr) and temperature (60 – 90oC) on pigment adsorption. Four adsorption isotherms were used to model the equilibrium data for both adsorbents (AFK and BN), namely Langmuir, Freundlich, Sips and Redlich-Peterson models. The Sips model provides the best correlation and adsorption occurred in monolayer. Kinetic adsorption data were analyzed using the pseudo-first order, pseudo-second order, and intraparticle diffusion models. The regression results showed that the adsorption kinetics was more accurately represented by the pseudo-first order kinetic model. Intraparticle diffusion studies reveals that pore diffusion is the controlling mechanism. Thermodynamic parameters, ?G, ?H and ?S, were calculated as a function of both temperature and adsorbent dosage. The values of enthalpy change were positive and greater than 40 kJ/mol in all cases, indicating that the bleaching process is endothermic and chemisorption in nature. The results suggest that AFK could be employed as low-cost alternative for removal of pigments from vegetable oil though BN is better.
