Allelic diversity of merozoite surface protein 2 gene of P falciparum among children in Osogbo, Nigeria

Abstract: The genetic diversity of Plasmodium falciparum (P falciparum) infections in humans is implicated in the pathogenesis of malaria . This study provides the first estimate of the genetic diversity and genotype multiplicity of Plasmodium falciparum infection in children with uncomplicated P falciparum malaria in Osogbo , Nigeria. One hundred and one isolates were used for analysis of parasite population polymorphism and genotyped by nested-PCR of merozoite surface protein 2 (MSP2 ) block 3 . Amplicons were obtained for all the 101 genotyped samples in MSP2 PCR with 9 alleles varying in size between 300 and 800 base pair. Thirty -three (31.7%) samples had FC27 allele while 27 (26.7%) had 3D7 allele and 35 (34.7%) had mixed alleles (3D7+FC27). The Multiplicity of Infection (MOI) in the population was 1.6 . Children in the age group of > 4‐ 8 years had the highest number of different genotypes in their samples (1.8). The number of MSP2 bands per isolate was lower in the older age group (1.3) but the difference was not statistically significant. Children with parasite density range 5001 ‐10 000 had the highest MOI of 2 while those with parasite density range 1000 ‐5000 had the lowest of 1.5. In conclusion , the present study shows that the field isolates are highly diverse in respect of MSP2 and multiplicity of infection was neither age nor parasite density dependent in the study population .

Use of Essential Oils in Food Preservation

Abstract: Various secondary metabolites such as essential oils (EOs) are produced by plants which, when extracted and concentrated, find their application in pharmaceutical, sanitary, cosmetic, agricultural, and food industries. There is an increasing interest in natural products, intended not only to delay/prevent the onset of chronic degenerative diseases, but also to prevent the deterioration of fats and other constituents of foodstuffs. EOs have been identified as natural food additives which can find useful application in food preservation. The objective of this chapter is to briefly describe the potential usage of EO in food preservation.

Factors Associated with Pastoral and Crop Farmers Conflict in Derived Savannah Zone of Oyo State, Nigeria

Abstract: The study investigated the factors associated with pastoral and crop farmers conflict in derived savannah zone of Saki-West Local Government Area of Oyo State. Eighty respondents were randomly selected from eight villages in the study area. The data collected were subjected to both descriptive (frequency counts and percentage) and inferential (Chi-square) statistical analysis. The result of the analysis reveals that majority (73.8%) of the respondents were males while others (26.3%) were females. The result further shows that most of respondents (70.1%) are aged between 30-49 years and more than three quarters (83.8%) of respondents in the study area were married, only 8.8% are single. Chi-square analysis showed that age ( χ 2 =38.75), Gender (χ 2 = 18.05), Marital status ( χ 2 = 47.80), education (χ 2 = 59.05), religion ( χ 2 = 36.33) and years of residence ( χ 2 = 56.00) are significantly related with causes of conflict. Informal institutions are preferred by the respondents in conflict resolution.

Volatile leaf oil constituents of three Eucalyptus Species from Nigeria

Abstract: The composition of the essential oils of the leaves of three Eucalyptus species: E. alba Reinw ex Blume, E. deglupta Blume (syn. E. naudiniana F.v.M.) and E. saligna Sm. growing in Nigeria were determined by the use of GC and GC-MS. The leaf essential oil of E. deglupta predominantly comprised sesquiterpenoids (48%), of which E-nerolidol was the major component (34.8%). E. alba and E. saligna volatile oils contained monoterpenoids in substantial amounts and the main constituents were α-thujene (32.9-63.8%), α-pinene (0.7-24.7%), p-cymene (0.6-12.9%) and 1,8-cineole (12.2-13.3%).
