BACKGROUND Few population-based studies have assessed the prevalence and the risk factors of non-allergic rhinitis (NAR) in comparison to allergic rhinitis (AR). Moreover, epidemiologic data on rhinitis in the elderly subjects and in southern Europe are scarce. OBJECTIVE This study aimed at estimating the prevalence and at comparing the risk factor distribution of AR and NAR in a general popu...

Our previous studies analyzing medaka mutants defective in primordial germ cell (PGC) migration identified cxcr4b and cxcr7, which are both receptors of the chemokine sdf1/cxcl12, as key regulators of PGC migration. Among PGC migration mutants, naruto (nar) is unique in that the mutant phenotype includes gross morphological abnormalities of embryos, suggesting that the mutation affects a broade...

Reaction of Li(3,5-R(2)-pyrazolide) (R = tBu or Ph, dXpz) with Mo(NAr)(CHCMe(2)Ph)(OTf)(2)(DME) yields Mo(NAr)(CHCMe(2)Ph)(dXpz)(2) in good yield. These complexes react with alcohols or the surface silanols of silica, to yield bis-alkoxy and surface mono-siloxy alkene metathesis catalysts, respectively.

Monaryloxide pyrrolide (MAP) molybdenum imido alkylidene complexes of the type Mo(NAr)(CHCMe2R)(Me2Pyr)(OR′) (Me2Pyr = 2,5dimethylpyrrolide) have been prepared in which NAr is an ortho-substituted phenylimido group (X = Cl (NAr), CF3 (NAr ), i-Pr (NAr), t-Bu (NAr), mesityl (NAr), or TRIP (TRIP = triisopropylphenyl; NAr)) and OR′ = O-2,3,5,6(C6H5)4C6H (OTPP), O-2,6-(2,4,6-Me3C6H2)2C6H3 (OHMT), o...

We extend the Bayesian framework to Multi-Layer Perceptron models of Non-linear Auto-Regressive time-series. The approach is evaluated on an artificial time-series and some common simplifications are discussed.

Reaction of the dimeric zirconium imido compound [Zr2(mu-NAr)2Cl4(THF)4] with tris(3,5-dimethylpyrazolyl)methyl silane very selectively gave [Zr{(Me2pz)2Si(Me)NAr}Cl3] (1), a highly active pre-catalyst for ethylene polymerisation; a more general and versatile route to N3 donor heteroscorpionate compounds was achieved via the protio ligand (Me2pz)2CHSi(Me)2N(H)iPr for which neutral and cationic ...

We report here the characterization of the catalytic component (ISP(NAR)) of a new naphthalene dioxygenase from Rhodococcus sp. strain NCIMB12038. The genes encoding the two subunits of ISP(NAR) are not homologous to their previously characterized counterparts in Pseudomonas. The deduced amino acid sequences have only 33 and 29% identity with the corresponding subunits in Pseudomonas putida NCI...

A tungsten neopentylidene complex has been found to decompose to yield a heterochiral dimer that contains a W=W double bond and no bridging ligands. Decompositions of related bisalkoxide complexes also yield compounds that contain an "unsupported" W=W double bond, while a sample of [Mo(NAr)(CH2-t-Bu)(OC6F5)]2 has been found to be a homochiral species related to [W(NAr)(CH2-t-Bu)(OC6F5)]2.
