Background: Nasal polyps, a common clinical problem, are characterized by eosinophilic and mast cell inflammation.  The role of allergy and IgE in pathogenesis of nasal polyps is still unclear.  IgE receptors are important components of the immunological pathway in allergic and inflammatory diseases. Objective: To determine if the low affinity IgE receptor (CD23) is presented on nasal polyp tis...

this study investigated the presence of mast cells in inflammatory aural polyps using light microscopy. the number of mast cells was increased in all examined cases and varied from 2.33 to 41.54 per mm2• the cells were located most commonly around small blood vessels. occurrence of mast cells was not different in various types of polyps, but their density was severely increased in active inflam...

ATP-dependent glucokinase is suggested to have evolved from a hypothetical polyphosphate (polyP)-dependent glucokinase (polyP-GK) via a bifunctional polyP/ATP glucokinase (polyP/ATP-GK). Here we showed that polyP-GK is present in a polyP-accumulating bacterium, Microlunatus phosphovorus. The polyP-GK produced glucose-6-P(i) from glucose and polyP, but it could not phosphorylate glucose with ATP...

the pathogenetic mechanism of nasal polyps remains unknown, although allergy has been cited as an important factor in the etiology of nasal polyposis. currently there is no definite histological criterion for differentiation of allergic from inflammatory nasal polyp. however, in a few studies, tissue eosinophil count has been used for this. this study aimed to find out the agreement rate of ski...

A recent study found aural abscessation to be a significant cause of morbidity and mortality in free-living eastern box turtles (Terrapene carolina carolina) in Virginia (1). Though its etiology remains unknown, hypovitaminosis A has been suggested based on a similar lesion occurring in captive chelonia fed diets deficient in vitamin A (4). This hypothesis was supported by significantly greater...

The Revo:oveR installation is a collection of six co-located installations exploring multimodal interaction, self-evolving aural and visual fabric, integration of architectural space, and the notion of communal art. The interactive aural communal soundscape Elemental and one of the two physical sculptures titled Cyrene Reefs exhibited at NIME 2009 can be seen as the core aural components of the...

Acoustic scientists and aural architects are fundamentally different. The former have the skill and experience to design a space that will have specific measurable acoustic properties (physical acoustics). The latter are able to discover what aural properties would be functional and desirable for the inhabitants (cultural acoustics). By focusing on aural architecture, we can design (real or vir...

OBJECTIVES To report the prevalence and demographics of temporomandibular disorder (TMD) within a population of clinic patients and to describe the prevalence of revisited and new, previously unstudied, aural symptoms described by a sample of these patients with TMD (hereinafter "TMD patients"). DESIGN A retrospective evaluation of patient records was completed to determine the percentage and...
