RESULTS: BLLs in 165 children of Guiyu ranged from 4.40 to 32.67 [micro]g/dL with a mean of 15.3 [micro]g/dL, whereas BLLs in 61 children of Chendian were from 4.09 to 23.10 [micro]g/dL with a mean of 9.94 [micro]g/dL. Statistical analyses showed that children living in Guiyu had significantly higher BLLs compared with those living in Chendian (p<<0.01). Of children in Guiyu, 81.8% (135 of 165)...

The cloning and sequencing of the small subunit (SSU) ribosomal DNA gene from Kudoa rosenbuschi (myxosporean species associated with post-mortem myoliquefaction process in the Argentinean hake Merluccius hubbsi) is reported. The SSU rDNA was found to contain 1740 bp with a single polymorphic site with either a C or T at position 221. The sequence data obtained in this study and those known sequ...

Homologous recombination repair (HRR) plays an important role in protection against carcinogenic factors. Genes regulating the HRR mechanisms may impair their functions and consequently result in increased cancer susceptibility. RAD 51 and XRCC3 are key regulators of the HRR pathway and genetic variability in these may contribute to the appearance and progression of various cancers including he...
