Addition of four equivalents of lithium 2,5-dimethylpyrrolide to a solution of [Mo(NAr)(OR(F6))(2)(CHC(5)H(4))](2)Fe (OR(F6)=OCMe(CF(3))(2)) in dichloromethane led to [Mo(NAr)(Me(2)Pyr)(2)(CHC(5)H(4))](2)Fe (2; Me(2)Pyr=2,5-dimethylpyrrolide) and lithium hexafluoro-tert-butoxide, which crystallizes out upon cooling the reaction mixture to -35 degrees C. Attempts to prepare parent pyrrolide comp...

BACKGROUND Chronic rhinitis is a heterogeneous group of diseases that cause nasal inflammation. And the nose may be a window into the lung in the concept of "one airway one disease." OBJECTIVE This study was conducted to evaluate differences between the different forms of chronic rhinitis in terms of lower airway inflammation. METHODS Patients that attended the allergy clinic and presented ...

RHINITIS IS A GLOBAL PROBLEM AND IS DEFINED AS THE PRESENCE OF AT LEAST ONE OF THE FOLLOWING: congestion, rhinorrhea, sneezing, nasal itching, and nasal obstruction. The two major classifications are allergic and nonallergic rhinitis (NAR). Allergic rhinitis occurs when an allergen is the trigger for the nasal symptoms. NAR is when obstruction and rhinorrhea occurs in relation to nonallergic, n...

BACKGROUND The surgical decision of performing anatomic resection (AR) or nonanatomic resection (NAR) in patients with hepatocellular carcinoma remains controversial. The aim of the current study is to conduct a meta-analysis on published results to compare surgical outcomes after AR and NAR. METHODS A comprehensive search of the Pubmed, Ovid-Medline, Embase, Cochrane library, and Science Cit...

BACKGROUND Bradykinin may contribute to the pathogenesis of allergic rhinitis. Like histamine, nasal challenge with bradykinin induces rhinorrhoea, nasal blockage, and plasma protein leakage. Their comparative nasal potencies have not, however, been fully elucidated. METHODS Three double blind, randomised, placebo controlled and cross-over studies were undertaken to compare objectively the na...

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...
