The construction sector makes significant contribution to employment, domestic capital formation and the Gross Domestic Product (GDP). However, the Nigerian Construction Sector (NCS) is beset by a number of challenges including over-dependent on foreign inputs, economic volatility, low linkages and poor project cost and time performance. The study investigates the impact of the construction sector on the GDP using a 47-year annualized Time Series Data (TSD) gotten from the United Nations Statistics Department (UNSD) database. The study employs econometric methodology which involves series of tests and procedures including tests for unit root and cointegration and Polynomial Distributed Lag (PDL) model. The summary of the estimates including the PDL indicate significant effect of the construction sector on the GDP only when the lag of the GDP is not included as one of the regressors. The study concludes that the effect of the construction sector on the GDP is not robust. Finally, the study recommends for a new national housing and transport infrastructure policy for the sustainable development of the Nigerian constructed infrastructure facilities. The study has demonstrated the relationship between the NCS and GDP. The study added to the body of knowledge by using time series data involving the use of distributed lag model (DLM), autoregressive distributed lag (ADL) model and polynomial distributed lag (PDL) model to assess the relationship.

Submicroscopic duplication of 8q24.3 region is a potential candidate for disorders of sex development: Some of the disorders of sex development (DSD), including 46, XX testicular DSD formerly called "XX maleness" and 46, XY DSD with partial or complete gonadal dysgenesis primarily affect the gonads. Genetic alterations in ten unrelated females with complete 46, XY gonadal dysgenesis (GD) were analyzed using an Array 2.7 M platform with whole genome coverage. The analysis result suggested that the most significant region maps to chromosome 8q24.3 which were previously reported by another independent study with a similar patient cohort and this region being probable candidate related to complete 46, XY GD.

WOS: 000305914400025, Backgrounds: Despite rapid developments in the science of medicine, increased number of innovative laboratory and imaging technologies; autopsies have a crucial role in gathering and transferring valuable information. Methods: In this study; medical records and autopsy reports of forensic cases resulting in death between 2006 and 2009 in Sivas were examined, and evaluated as for medical and socio-demographic aspects. Results: Total of 540 cases assessed consisted of 393 (72.8%) males mostly (n=159; 29.4%) over 60 years of age. Deaths were mostly seen during summer (n=154; 28.5%), and suspected deaths lead the way (n=144; 26.7%), followed by traffic accidents (n=138; 25.6%). Death certificates were arranged for 425 (78.7%) cases following postmortem examinations. Conclusions: Findings in this study have shown some similarities with those of the literature. Since highest mortality rates are seen secondary to accidents, relatively simple preventive measures have vital importance. Traffic accidents, and falls from height which are among preventable causes of mortality still remain to be a challenging problem in our country and implementation of necessary safety measures, and training on this subject are of paramount importance.
