Four Gram-positive bacteria, strains A1-17B(T), A1-22(T), A1-3(T) and A1-8, isolated from the air in the Russian space laboratory Mir, were subjected to a polyphasic taxonomic study. Phylogenetic analysis of the bacteria based on their 16S rDNA sequence showed that they belong to the genera Rothia (A1-17B(T)), Rhodococcus (A1-22(T)) and Arthrobacter(More)
With the presentation of more reliable groupcast proposal for IEEE802.11 WLAN, the QoS of video transmission based on groupcast (multicast / broadcast) is improved. To adapt the network load and bandwidth dynamic change in WLAN environment, we design a flexible optimization mechanism that integrates video steam priority character with more reliable(More)
Certain human subpopulations are metabolically healthy but obese, or metabolically obese but normal weight; such mutations uncouple obesity from glucose intolerance, revealing pathways implicated in Type 2 diabetes. Current searches for relevant genes consume significant effort. We have reported previously a novel double bromodomain protein called Brd2,(More)
Sertraline, one of the oldest antidepressants, remains to be the most efficacious treatment for depression. However, major depression disorder (MDD) is characterized by altered emotion processing and deficits in cognitive control. In cognitive interference tasks, patients with MDD have shown excessive hypothalamus activity. The purpose of this study was to(More)
BACKGROUND Platelet-rich plasma (PRP) promotes regeneration of bone, presumably through the action of concentrated growth factors. However, it is not clear how PRP affects the inflammatory response. The purpose of this study was to analyze the growth factors in PRP and to study the effects of PRP on monocyte cytokine release and lipoxin A(4) (LXA(4))(More)
Neutrophils from people with poorly controlled diabetes present a primed phenotype and secrete excessive superoxide. Phospholipase A(2) (PLA(2))-derived arachidonic acid (AA) activates the assembly of NADPH oxidase to generate superoxide anion. There is a gap in the current literature regarding which PLA(2) isoform regulates NADPH oxidase activation. The(More)
A hallmark of bacterial biofilms is a self-produced extracellular matrix of exopolysaccharide, extracellular DNA (eDNA) and proteins that hold bacterial cells together in the community. However, interactions among matrix components and how the interactions contribute to the formation of matrix remain unclear. Here, we show the physical interaction between(More)
On the basis of phenotypic and genotypic characteristics and 16S rRNA gene sequence analysis, novel species belonging to the genera Sphingomonas and Brevundimonas were identified from samples taken from the Russian space laboratory Mir. Strain A1-18(T) was isolated from the air. 16S rDNA sequence analysis showed that strain A1-18(T) formed a coherent(More)
PURPOSE SLC26A6 is a multifunctional anion transporter with a critical physiological role in the transport of oxalate anions. Recognizing a genetic variant of SLC26A6 would advance our understanding of oxalate transport in the formation of calcium oxalate stones. MATERIALS AND METHODS All nsSNPs (nonsynonymous single nucleotide polymorphisms) reported in(More)
Classification of strain W3-B1, which was isolated from condensation water in the Russian space laboratory Mir, was investigated by a polyphasic taxonomic approach. Cells of strain W3-B1 were nonmotile, asporogenous, gram-negative slender rods with rounded ends. 16S rRNA gene sequence analysis indicated that organism should be placed in the genus(More)
