OBJECTIVE The aim of the present study was to investigate the effect of allergic rhinitis on the success of the operation in chronic otitis surgery by using score for allergic rhinitis (SFAR). MATERIALS AND METHODS In the present study; 121 patients, who underwent type 1 tympanoplasty were examined retrospectively. SFAR of all patients were recorded. The graft success rates of 26 patients wit...

use of the growth indices is a method to assessment of intercropping efficiency. in order to evaluation growth indices of soybean, sweet basil and borage in intercropping with different ratios, an experiment base on randomized complete block design was conducted with 9 treatments and 3 replications at north khorasan in 2011. treatments were consisted of the plants pure culture, replacement seri...

in order to investigate the effect of different weed-free and weed-infested periods on the growth indices of black seed, a field experiment was conducted at the agricultural research station of ferdowsi university of mashhad, during 2009-2010 growing season. the experiment was laid out in randomized complete block design with 12 treatments and 3 replications. twelve experimental treatments cons...

We compared the rise in nasal airway resistance (NAR) provoked by topical application of substance P (SP) and of methacholine (MCH) in seventeen patients suffering from rhinitis and fourteen control subjects. Challenges with SP or MCH were separated by a week or more. NAR was measured by posterior rhinomanometry before and 10 min after intranasal administration of SP (10-40 nmol) or MCH (3-12 m...

Literature is divided on whether enterprise systems promote or hinder organizational agility. To the best of our knowledge, this paradox has never been rigorously theoretically analyzed nor empirically investigated. This paper seeks to address this paradox by leveraging upon innovation assimilation literature and knowledge based and capabilities based views of organizations. We propose a theore...

Background: Acute appendicitis (AA) has a lifetime risk of 8.3% with consequent 23% emergency appendectomy. In atypical presentation, making clinical diagnosis is difficult, leading to high perforation rate (PR) or misdiagnoses and negativeappendectomy rates (NAR). This study aimed establish NAR explore the associated factors possible attainable solutions reduce it in urban referral hospitals T...

Introduction In contrast to the significant number of studies indicating the impairment of QoL in AR, the degree of impairment in Quality of Life (QoL) in NAR remains underexposed. Again in contrast to AR, almost no evidence-based therapies for NAR patients exist. We assessed QoL in NAR compared to healthy controls and AR patients as positive controls and investigated whether the use of treatme...

Plant growth, photosynthesis and leaf constituents were examined in the wild-type (WT) and mutant nar1 of barley (Hordeum vulgare L. cv. Steptoe) that contains a defective structural gene encoding NADH-dependent nitrate reductase (NADH-NAR). In controlled environment experiments, total biomass, rates of photosynthesis, stomatal conductance, intercellular CO(2) concentrations and foliar non-stru...
