BACKGROUND The natural history of wheat allergy varies among different countries. OBJECTIVE To study the age of resolution from IgE-mediated wheat allergy and to define the predictors of wheat tolerance. METHODS Patients with a history of immediate reactions after wheat ingestion were enrolled. Skin prick test (SPT) and measurement of serum specific IgE (sIgE) to wheat and ω-5 gliadin were ...

BACKGROUND The accuracy and precision of quantitative coronary angiography (QCA) software dedicated for bifurcation lesions compared with conventional single-vessel analysis remains unknown. Furthermore, comparison of different bifurcation analysis algorithms has not been performed. METHODS Six plexiglas phantoms with 18 bifurcations were manufactured with a tolerance < 10 µm. The bifurcation...

Numerous studies have demonstrated that tree survival is influenced by negative density dependence (NDD) and differences among species in shade tolerance could enhance coexistence via resource partitioning, but it is still unclear how NDD affects tree species with different shade-tolerance guilds at later life stages. In this study, we analyzed the spatial patterns for trees with dbh (diameter ...

Technical improvements have allowed to significantly reduce the diameter of endoscopes used to examine the upper gastrointestinal tract. Hence, transnasal introduction of endoscopes used to perform a standard esogastroduodenoscopy (EGD) has become possible. Transnasal EGD (T-EGD) is better tolerated by patients than conventional EGD (C-EGD), and it presents the advantage of requiring no sedatio...

AIM To examine the current status of standardization of endodontic irrigation needles produced by different manufacturers. METHODOLOGY Measurements of needle internal and external diameter were conducted under scanning electron microscopy and stereoscopic microscopy to determine the incidence and degree of deviation from ISO 9,626:1991 and ISO 9,626:1991/Amd 1:2001 specification. RESULTS No...

Potential relative increment (PRI) is a new method to derive optimal diameter growth equations using inventory information from a large public database. Optimal growth equations for 24 species were developed using plot and tree records from several states (Michigan, Minnesota, and Wisconsin) of the north central US. Most species were represented by thousands of individuals measured across an ex...

In this paper, we focus on deriving low-diameter networks, beginning with D = 2, the next best value to that of the complete network, and proceeding to somewhat larger (constant) values leading to more economical networks. We show that perfect difference networks (PDNs), which are based on the mathematical notion of perfect difference sets, offer a diameter of 2 in an asymptotically optimal man...

The directional hypercube (Dcube) which is a cost-effective variation of the traditional binary hypercube is introduced and analyzed in this paper. It employs directional (simple duplex) links only. The Dcube is defined and its key properties are derived including diameter, bandwidth, and connectivity. The diameter is at most 2 greater than that for a hypercube of the same size; the bandwidth i...
