RESUMO
We report two complete mitochondrial genomes of Cottus pollux based on specimens collected from Deokdong and Hoam Streams in the Republic of Korea. The two complete mitochondrial genomes were 16,558 and 16,557 bp long. Both contain the 37 standard genes (13 protein-coding genes, 22 transfer RNA genes, two ribosomal RNA genes, and one control region) in the same order and have similar nucleotide compositions. According to the phylogenetic tree constructed using the maximum-likelihood method, C. pollux is closely related to C. reinii. The genetic information provided by the complete mitochondrial genome of C. pollux will contribute to an understanding of the phylogenetic position, evolutionary relationships, and biogeographical patterns of this species within the genus Cottus.

RESUMO
The aim of this meta-analysis was to determine whether pulsatile perfusion during cardiac surgery has a lesser effect on renal dysfunction than nonpulsatile perfusion after cardiac surgery in randomized controlled trials. MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials were used to identify available articles published before April 25, 2014. Meta-analysis was conducted to determine the effects of pulsatile perfusion on postoperative renal functions, as determined by creatinine clearance (CrCl), serum creatinine (Cr), urinary neutrophil gelatinase-associated lipocalin (NGAL), and the incidences of acute renal insufficiency (ARI) and acute renal failure (ARF). Nine studies involving 674 patients that received pulsatile perfusion and 698 patients that received nonpulsatile perfusion during cardiopulmonary bypass (CPB) were considered in the meta-analysis. Stratified analysis was performed according to effective pulsatility or unclear pulsatility of the pulsatile perfusion method in the presence of heterogeneity. NGAL levels were not significantly different between the pulsatile and nonpulsatile groups. However, patients in the pulsatile group had a significantly higher CrCl and lower Cr levels when the analysis was restricted to studies on effective pulsatile flow (P < 0.00001, respectively). The incidence of ARI was significantly lower in the pulsatile group (P < 0.00001), but incidences of ARF were similar. In conclusion, the meta-analysis suggests that the use of pulsatile flow during CPB results in better postoperative renal function.

An isolated bacterium that converted unsaturated fatty acids to hydroxy fatty acids was identified as Stenotrophomonas nitritireducens by API analysis, cellular fatty acids compositions, sequencing the full 16S ribosomal ribonucleic acid, and evaluating its nitrite reduction ability. S. nitritireducens has unique regio-specificity for C16 and C18 cis-9 unsaturated fatty acids. These fatty acids are converted to their 10-hydroxy fatty acids without detectable byproducts. Among the cis-9-unsaturated fatty acids, S. nitritireducens showed the highest specificity for linoleic acid. The cells converted 20 mM linoleic acid to 13.5 mM 10-hydroxy-12(Z)-octadecenoic acid at 30 degrees C and pH 7.5 with a yield of 67.5% (mol/mol).
