Anaerobic ammonium oxidation (anammox) is an important process in the marine nitrogen cycle. However, little is known about the distribution, diversity and abundance of anammox bacteria in inland river ecosystems. Here, we found the presence of diverse anammox bacteria in a freshwater river - the Qiantang River, Zhejiang Province (China). The phylogenetic(More)
BACKGROUND Merkel cell polyomavirus (MCPyV) was identified newly (2008) and is believed to be an etiologic factor of Merkel cell carcinoma (MCC). Recent molecular and serological data suggest that MCPyV infection is common in the general population. OBJECTIVES The aim of this study was to investigate the age of primary exposure to MCPyV. STUDY DESIGN A(More)
Efficient biological nitrogen removal from pharmaceutical wastewater has been focused recently. The present study dealt with the treatment of colistin sulfate and kitasamycin manufacturing wastewater through anaerobic ammonium oxidation (ANAMMOX). The biotoxicity assay on luminescent bacterium Photobacterium phosphoreum (T3 mutation) showed that the(More)
The identification of quantitative trait loci (QTLs) that are stable and consistent across multiple environments and populations plays an essential role in marker-assisted selection (MAS). In the present study, we used 28,861 simple sequence repeat (SSR) markers, which included 12,560 Gossypium raimondii (D genome) sequence-based SSR markers to identify(More)
The expression of galectin-1, one of the most important lectins participating in the malignant tumor development, has been shown to be regulated by hypoxia, but its exact mechanism remains elusive. Here, we find that ectopically expressed hypoxia-inducible factor (HIF) 1alpha protein, an oxygen-sensitive subunit of HIF-1 that is a master factor for cellular(More)
Ethylene response factors (ERF) play crucial roles in plant development and response to stresses. Here, a novel cDNA fragment (MsERF8) encoding an ERF protein with an AP2 domain was isolated and characterized from alfalfa. The MsERF8 cDNA has an open reading frame of 603 bp and encodes a nuclear protein of 201 amino acids. Q-RT-PCR analysis revealed that(More)
The autotrophic nitrogen removal process in the granular sludge bed reactor (GSB-ANR process) is a new and promising biotechnology for nitrogen removal from wastewater, which requires single reactor, simple operation and inorganic carbon. The results showed that the GSB-ANR process could be successfully started up with nitrifying granular sludge as(More)
The granule floatation is a serious issue of the anammox (anaerobic ammonium oxidation) process when high loading rates are applied that results in instability or even system collapse. The present study reports the granule floatation in an anammox reactor when high loading rates were applied. The comparison of enlarged photos taken for the settling and(More)
Fractures of the posterior wall of the acetabulum form a special group in acetabular fractures. This study aims to evaluate the results in the management of such fractures. Thirty-two patients with fractures of posterior wall of acetabulum were reviewed retrospectively. The follow-up period was 7 (range 3–10) years. Twenty-four were associated with initial(More)
OBJECTIVE To assess the association of three polymorphisms (14-bpINS/DEL, +3035C/T and +3142C/G) in the 3' untranslated region (3'UTR) of HLA-G gene and systemic lupus erythematosus (SLE) in Yunnan. METHODS A case-control study has been carried out on 206 SLE patients and 212 healthy controls. Genotypes of 14-bpINS/DEL (rs1704), +3035C/T (rs17179108) and(More)
