AIMS  The purpose of this study was to search for the relationship between quorum sensing (QS) and Cu²⁺ resistance in Acidithiobacillus ferrooxidans. METHODS AND RESULTS  Resistance to Cu²⁺ of A. ferrooxidans significantly decreased with the treatment dose of a synthetic QS blocker (5Z)-4-bromo-5-(bromomethylene)-2(5H)-furanone (FUR). Relative differences(More)
Geniposide, a main iridoid glucoside component of gardenia fruit, has been shown to possess anti-inflammatory activity. However, its potential use for acute lung injury (ALI) has not yet been studied. The aim of this study was to evaluate the anti-inflammatory properties of geniposide using a mouse ALI model. ALI was induced by intranasal injection of(More)
To survive, plants possess elaborate defence mechanisms to protect themselves against virus or pathogen invasion. Recent studies have suggested that plant mitochondria may play an important role in host defence responses to biotic stresses. In contrast with animal mitochondria, plant mitochondria possess a unique respiratory pathway, the cyanide-insensitive(More)
OBJECTIVE To assess the effectiveness of a three-stage intervention to reduce caesarean deliveries in a Chinese tertiary hospital. METHODS A retrospective study was conducted to assess whether educating staff, educating patients and auditing surgeon practices (introduced in 2005) had reduced caesarean delivery rates. Multiple logistic regression was used(More)
STUDY DESIGN A retrospective study had been conducted to evaluate the efficacy and safety of anterior cervical discectomy and fusion (ACDF) at C2-C3 for traumatic spondylolisthesis of the axis (TSA). OBJECTIVE The present study had been done to evaluate the results and feasibility of the surgical treatment with ACDF at C2-C3, for the fixation of unstable(More)
By four different methods, Acidithiobacillus ferrooxidans cells were immobilized by the complex of PVA and sodium alginate. The beads formed by these different methods were evaluated in terms of relative mechanical strength, biological activity, dilatability, and so on. The results indicate that the technique utilizing the complex of PVA and sodium alginate(More)
Understanding of attributes of UML class diagram can be influenced by various factors. Semantic annotation for attributes can help model users understand their meaning precisely. As a result, services provided by the models can be better applied in the data processing tasks of the users. This paper proposes a method of semantic annotation of UML class(More)
The major source of endogenous hydrogen peroxide is generally thought to be the respiratory chain of bacteria and mitochondria. In our previous works, mesosome structure was induced in cells during rifampicin effect, and the mesosome formation is always accompanied by excess hydrogen peroxide accumulation in bacterial cells. However, the underlying(More)
