Pulpal inflammation can result from mechanical, chemical, or bacterial insult. The initial vascular reactions during inflammation in the dental pulp are vasodilation and increased vascular permeability. These vascular reactions are induced by activation of sensory nerve endings of C-fiber. This condition is called neurogenic inflammation. The inflammatory process in the pulp does not differ sig...

Intimin is a bacterial outer membrane protein required for intimate attachment of enterohemorrhagic and enteropathogenic Escherichia coli (EHEC and EPEC) to mammalian cells. beta1-chain integrins have been proposed as candidate receptors for intimin. We found that binding of mammalian cells to immobilized intimin was not detectable unless mammalian cells were preinfected with EPEC or EHEC. beta...

Treatment of functional gastrointestinal disorders remains difficult with many very different approaches showing similar response rates, regardless of whether they target luminal contents (e.g., presumed bacterial overgrowth), signaling within the gut wall (e.g., serotonin agonists or antagonists) or processing in the brain (e.g., cognitive behavioral therapy). Discrepancies between recent clin...

The present study was conducted to compare the effect of two barnyard millet varieties viz. Echinochloa frumentacea (L.) (HNJZ) and crusgalli var. austro-japonensis (BZ), on fertility physicochemical properties alkaline soil Ningxia, China. Soil rhizosphere BZ HNJZ with three replicates (5 plants from each replicate) were collected for bacterial communities metagenomic profiling six samples tre...

Vibrio harveyi is one of the major pathogens of aquatic organisms, affecting both vertebrates and invertebrates, and causes important losses in the aquaculture industry. In order to develop novel methods to control disease caused by this pathogen, we need to obtain a better understanding of pathogenicity mechanisms. Sensing of catecholamines increases both growth and production of virulence-rel...

Fusarium graminearum is the main causal pathogen affecting small-grain cereals, and it produces deoxynivalenol, a kind of mycotoxin, which displays a wide range of toxic effects in human and animals. Bacterial strains isolated from peanut shells were investigated for their activities against F. graminearum by dual-culture plate and tip-culture assays. Among them, twenty strains exhibited potent...

Mixtures of biological control agents can be superior to individual agents in suppressing plant disease, providing enhanced efficacy and reliability from field to field relative to single biocontrol strains. Nonetheless, the efficacy of combinations of Pseudomonas fluorescens A506, a commercial biological control agent for fire blight of pear, and Pantoea vagans strain C9-1 or Pantoea agglomera...
