The community structure and diversity of anaerobic ammonium oxidation (anammox) bacteria in the surface sediments of equatorial Pacific were investigated by phylogenic analysis of 16S rRNA and hydrazine oxidoreductase (hzo) genes and PCoA (principal coordinates analysis) statistical analysis. Results indicated that 16S rRNA and hzo sequences in the P2 (off(More)
Neuroinflammation plays an important role in cerebral ischemia/reperfusion (I/R) injury. The P2X7 receptor (P2X7R) has been reported to be involved in the inflammatory response of many central nervous system diseases. However, the role of P2X7Rs in transient global cerebral I/R injury remains unclear. The purpose of this study is to determine the effects of(More)
Nitrilases are enzymes widely expressed in prokaryotes and eukaryotes that utilize a Cys–Glu–Lys catalytic triad to hydrolyze non-peptide carbon–nitrogen bonds. Nitrilase from Syechocystis sp. Strain PCC6803 (Nit6803) shows hydrolysis activity towards a broad substrate spectrum, ranging from mononitriles to dinitriles and from aromatic nitriles to aliphatic(More)
NAC (NAM-ATAF1, 2-CUC2) family members play important roles in various environmental responses. Here, we cloned a full-length NAC gene (954 bp) from Solanum lycopersicum (SlNAC1). This gene belonged to ATAF subfamily which included ATAF1 and ATAF2 of Arabidopsis thaliana. SlNAC1 expression was induced by chilling stress (4°C), heat stress (40°C), high(More)
Monitoring cognitive load is important for the prevention of faulty errors in task-critical operations, and the development of adaptive user interfaces, to maintain productivity and efficiency in work performance. Speech, as an objective and non-intrusive measure, is a suitable method for monitoring cognitive load. Existing approaches for cognitive load(More)
Aldehyde dehydrogenase (ALDH) catalyzes the oxidation of aldehydes to carboxylic acids. Cyanobacterium Synechococcus contains one ALDH enzyme (Sp2771), together with a novel 2-oxoglutarate decarboxylase, to complete a non-canonical tricarboxylic acid cycle. However, the molecular mechanisms for substrate selection and cofactor preference by Sp2771 are(More)
The objective of this study was to screen for novel quorum-sensing inhibitors (QSIs) from traditional Chinese medicines (TCMs) that inhibit bacterial biofilm formation. Six of 46 active components found in TCMs were identified as putative QSIs based on molecular docking studies. Of these, three compounds inhibited biofilm formation by Pseudomonas aeruginosa(More)
BACKGROUND Foot-and-mouth disease (FMD) is an acute, highly contagious disease that infects cloven-hoofed animals. Vaccination is an effective means of preventing and controlling FMD. Compared to conventional inactivated FMDV vaccines, the format of FMDV virus-like particles (VLPs) as a non-replicating particulate vaccine candidate is a promising(More)
Cognitive load variations have been found to impact multimodal behaviour, in particular, features of spoken input. In this paper, we present a design and implementation of a user study aimed at soliciting natural speech at three different levels of cognitive load. Some of the speech data produced was then used to train a number of models to automatically(More)
Due to the limitation of single-level classification, existing fusion techniques experience difficulty in improving the performance of language identification when the number of languages and features are further increased. Given that the similarity of feature distribution between different languages may vary, we propose a novel hierarchical language(More)
