AIMS To isolate an alkaliphilic bacterium and to investigate its ability of extracellular reduction. METHODS AND RESULTS An alkaliphilic and halotolerant humus-reducing anaerobe, Bacillus pseudofirmus MC02, was successfully isolated from a pH 10·0 microbial fuel cell. To examine its ability of extracellular reduction, AQDS (anthraquinone-2, 6-disulfonae),(More)
The transformation of DDT was studied in an anaerobic system of dissimilatory iron-reducing bacteria (Shewanella decolorationis S12) and iron oxide (alpha-FeOOH). The results showed that S. decolorationis could reduce DDT into DDD, and DDT transformation rate was accelerated by the presence of alpha-FeOOH. DDD was observed as the primary transformation(More)
OBJECTIVE To explore the etiology of acute hepatitis hospitalized patients in Beijing Ditan Hospital from 2002 to 2011. METHODS We summed up the changes in the characteristics of the etiology of acute hepatitis of patients mentioned above, and preliminarily analyze the causes. RESULTS From 2002 to 2011, 6235 patients with acute hepatitis were admitted(More)
AIMS To isolate an iron-reducing bacterium and examine its ability of Fe(III) oxide reduction and dechlorination. METHODS AND RESULTS A fermentative facultative anaerobe, strain L17 isolated from subterranean sediment, can reduce Fe(III) oxides and carbon tetrachloride (CT). It was identified as Klebsiella pneumoniae by 16S rRNA sequence analysis. Strain(More)
Norepinephrine (NE) was investigated for its effect on progesterone secretion from 6-8 week gestation human trophoblast tissue cultured in serum-free medium. Norepinephrine (5 micrograms/ml) enhanced progesterone secretion significantly on the third day of treatment. The stimulatory effect of NE on progesterone production was abolished by the alpha(More)
Screening and identifying molecules target to checkpoint pathways has fostered the development of checkpoint-based anticancer strategies. Among these targets, inhibition of chk2 may induce cell death for tumors whose growth depends on enhanced chk2 activity. However, improvement of the potency and specificity of such therapeutics remains a major challenge.(More)
The effect of norepinephrine (NE) upon human chorionic gonadotrophin (hCG) production by 6-8 week gestation placental explants has been investigated. NE (5 micrograms/ml) enhanced hCG secretion significantly from the second day of treatment. The stimulatory effect of NE on hCG secretion could be abolished by the alpha 1-receptor specific antagonist prazosin(More)
The Publisher and Editor retract this article in accordance with the recommendations of the Committee on Publica tion Ethics (COPE). After a thorough investigation we have strong reason to believe that the peer review process was compromised.
OBJECTIVE To study the anti-endotoxin therapy on the plasma levels of nitric oxide, prostacyclin, tumor necrosis factor-alpha in patients with liver cirrhosis after hepatitis. METHODS Thirty patients with decompensated liver cirrhosis accepted anti-endotoxin therapy with oral Amoxycillin and Smedta for 2 weeks. Plasma levels of endotoxin, nitric oxide,(More)
Tissue-specific expression patterns of the paired type IV collagen genes COL4A5 and COL4A6 form the basis for organ involvement in X-linked Alport syndrome, a disorder in which these genes are mutated. We investigated the proximal promoter region of COL4A5 and COL4A6 using glomerular visceral epithelial cells, in which COL4A5 alone is transcribed;(More)
