Abstract: Objective: To reexamine literature and data on the effects of gene polymorphism on precocious puberty via a meta-analysis. Methods: Consultation of search engines Chinese Bio-medicine Database, China National Knowledge Infrastructure, Pubmed and Medline search resulted in a total of seven studies containing more than 4300 individuals from various ethnic backgrounds. To evaluate the risk of precocious puberty, odds ratios (OR) for all case-control studies were calculated. Results: In this meta-analysis no significant association of the gene polymorphism with precocious puberty in the combined case-control sample (OR=1.19, 95%CI: 0.88-1.62, P=0.26) was found. Conclusion: This study found no evidence of gene polymorphism being an independent risk factor of precocious puberty. Further studies are needed further understand the effects of the interactions between these genes and other genetic and/or environment factors on precocious puberty.

Abstract: There are several reasons why public power supply policy in Nigeria needs to be reviewed. This paper points out the justification based on the statistical inferences drawn from an elaborate nested experimental design model fitted to a 3-year historical life-data of power failure obtained from an electricity power agency in Nigeria. Our results suggest that energy crisis is at its threshold in Nigeria and it is therefore advocated that adequate and appropriate steps need to be taken to stave off the declining trend.
