BACKGROUND Laribacter hongkongensis is associated with community-acquired gastroenteritis and traveler's diarrhea and it can reside in human, fish, frogs and water. In this study, we performed an in-depth annotation of the genes in its genome related to adaptation to the various environmental niches. RESULTS L. hongkongensis possessed genes for DNA repair(More)
Alkaline exonuclease and single-strand DNA (ssDNA) annealing proteins (SSAPs) are key components of DNA recombination and repair systems within many prokaryotes, bacteriophages and virus-like genetic elements. The recently sequenced β-proteobacterium Laribacter hongkongensis (strain HLHK9) encodes putative homologs of alkaline exonuclease (LHK-Exo) and SSAP(More)
Inorganic polyphosphate (poly-P), guanosine pentaphosphate (pppGpp) and guanosine tetraphosphate (ppGpp) are ubiquitous in bacteria. These molecules play a variety of important physiological roles associated with stress resistance, persistence, and virulence. In the bacterial pathogen Mycobacterium tuberculosis, the identities of the proteins responsible(More)
Energy efficient transmission is crucial for future wireless communication systems and has attracted much attention. In this paper we study the coordinated beamforming optimization for multicell multiple-input single-output (MISO) downlink systems using the energy efficiency criterion, which is still an open problem to our best knowledge. The optimization(More)
BACKGROUND SXT is an integrating conjugative element (ICE) originally isolated from Vibrio cholerae, the bacterial pathogen that causes cholera. It houses multiple antibiotic and heavy metal resistance genes on its ca. 100 kb circular double stranded DNA (dsDNA) genome, and functions as an effective vehicle for the horizontal transfer of resistance genes(More)
This paper studies joint power allocation and beam-forming for energy efficient communication in coordinated multi-cell multi-user downlink systems. The considered energy efficiency maximization problem which takes both dynamic and static power consumption into account is non-convex and hard to tackle. To address it, the optimization problem is first(More)
The aim of the manuscript was to optimize formulations and preparation technologies of cataplasm of white mustard seed varnish, and to evaluate its anti-asthma effect on rats. The single factor experiments included spreading thickness, types of crosslinking agents, dihydroxyaluminum aminoacetate amount, sodium polyacrylate amount, types of adhesive agents(More)

AIM Corneal alkali burns are a severe disease and commonly encountered in the emergent clinic. A rapid medical treatment for the burn is very important. Gly-thymosin β4 (Gly-Tβ4) is a biomimic derivative of natural thymosin β4. The aim of this study is to evaluate the corneal recovery effects of Gly-Tβ4 topical therapy on alkali burns in rabbit corneas. (More)
