OBJECTIVE We evaluated, by means of a multicentre, prospective observational trial, the severity in term of symptoms and symptomatic drugs use and the presence of asthma in subjects with tree or cypress or olive, or ragweed or parietaria allergy and we evaluated also the efficacy of a consecutive 2-year specific sublingual immunotherapy treatment. PATIENTS AND METHOD Consecutive patients suff...
The kd-tree is a fundamental tool in computer science. Among other applications, the application of kd-tree search (by the tree method) to the fast evaluation of particle interactions and neighbor search is highly important, since the computational complexity of these problems is reduced from O(N2) for a brute force method to O(N log N) for the tree method, where N is the number of particles. I...
BACKGROUND Multiple sensitization is frequent among pollen-allergic patients. The goal of this study was to determine the diagnostic accuracy of the ImmunoCAP ISAC 112 (ISAC112) microarray in allergy to pollen from several taxa and its clinical utility in a Spanish population. METHODS Specific IgE was determined in 390 pollen-allergic patients using the ISAC112 microarray. Diagnostic accuracy...
To understand ecological factors mediating the spread of insect-borne plant pathogens, vector species for these pathogens need to be identified. Grapevine leafroll disease is caused by a complex of phylogenetically related closteroviruses, some of which are transmitted by insect vectors; however, the specificities of these complex virus-vector interactions are poorly understood thus far. Throug...
ABSTRACT The roles of Pineapple mealybug wilt-associated viruses (PMWaVs) and mealybug (Dysmicoccus spp.) feeding in the etiology of mealybug wilt of pineapple (MWP) were evaluated. Container-grown pineapple (Ananas comosus) plants from five commercially grown Hawaiian proprietary selections and a field study utilizing a randomized complete block design were used to test four treatments for ind...
The literature concerning the association between ants and the mealybugs causing pineapple wilt disease is surveyed. A great deal of data on this subject has been published in the relatively obscure technical papers and reports of the defunct Pineapple Research Institute of Hawaii. This review article is an attempt to bring this information to a broader audience and examine it in the context of...
Trees decline is a complex physiological disease that results from the interactions between several factors, one of which is heavy metal stress that ultimately leads to the death of trees. This experiment, which was conducted during 2016-2017 at the campus facility of the Department of Horticulture at Isfahan University of Technology, was conducted to investigate the effects of inoculation with...
There are six species in the genus Chamaecyparis worldwide, of which two, namely the Hinoki cypress (Chamaecyparis obtusa Sieb. et Zucc.) and Sawara cypress (Chamaecyparis pisifera Sieb. et Zucc.) are distributed in Japan (Maruyama et al., 2002). The Hinoki cypress is one of the most important commercial timber trees in Japan, representing about 25% of the plantation area in the country. Howeve...
A unique urban tree species identification project for the Mississippi State University campus was undertaken in the Spring of 2002. A collaborative effort between the MSU Forestry Department, Landscape Architecture Department and the U.S. Forest Service was initiated in an attempt to automate tree species identification from high-resolution multi-spectral imagery. Traditional image processing ...
