Catechol O-methyltransferase (COMT) inactivates neurotransmitters, hormones and drugs such as levodopa. COMT activity is inherited in an autosomal recessive manner and individuals with low activity have thermolabile COMT protein. A low activity allele has been demonstrated at codon 108/158 of the soluble and membrane bound COMT protein, respectively, whereby a G to A transition results in a valine to methionine substitution, rendering the protein more thermolabile. As ethnic differences in erythrocyte COMT activity have been previously demonstrated, the frequency of low activity alleles were investigated in 265 British Caucasian, 99 British South-west Asian and 102 Kenyan individuals. Genotyping of COMT codon 108/158 was performed using a minisequencing method. Erythrocyte COMT activity was measured in 60 British Caucasian individuals by radiochemical assay. The frequency of low activity alleles was 0.54 in Caucasians, 0.49 in South-west Asians, and 0.32 in Kenyans. There was a much lower frequency of individuals with homozygous low activity allele in the Kenyan population (9%) than in Caucasians (31%) or South-west Asians (27%). Erythrocyte COMT activity was lower and less thermostable in individuals with homozygous low activity alleles. The data provide molecular evidence that low COMT is less common in African individuals than the Caucasian population. PMID: 9682265 [PubMed - indexed for MEDLINE]

The research discussed in this book sought to penetrate the functional role fo teachers and students’ attitudes towards Christian Religious Education in Kenya. A mixed methods (qualitative and quantitative) approach was employed with the investigations being ‘ex post facto’ in design. A random stratified procedure was employed to select the constituents of the sample. The sample consisted of 49 teachers and 909 students. The methodology, findings, discussion, conclusions and recommendations of the research are presented in the book.

What entails the training of young children making them ready for primary school and in essence for the future? Are there specific items, procedures, factors, etc. that need to be considered for the successful achievements of this goal? Can anybody who loves children undertake teaching preschoolers? These are some of the question that Teaching children seeks to address. This book navigates the waters of preschool teaching – the process of learning, teaching methods, motivation, differences in children all thorough to evaluation as preschool children lay blocks for their future. The journey along this road of preschool education and training begins here.
