The present work analyses the airborne pollen dynamic of the atmosphere of Toledo (central Spain), a World Heritage Site and an important tourist city receiving over 2 millions of visitors every year. The airborne pollen spectrum, the annual dynamics of the most important taxa, the influence of meteorological variables and the risk of suffering pollen allergy are analysed. Results of the presen...

The present study provides an update on the betaxanthin (bx) compositions of red and yellow beetroots, yellow-coloured Swiss chard petioles, and yellow-orange cactus pear. Applying RP-HPLC coupled with positive ion electrospray mass spectrometry and by comparison with UV-vis and mass spectrometric characteristics as well as retention times of semi-synthesized reference compounds, 24 betaxanthin...

BACKGROUND Pollen allergens are one of the main contributors to the development and/or aggravation of allergic rhinitis, allergic conjunctivitis, and asthma. OBJECTIVE An examination of the airborne pollen in residential areas should be conducted to aid the diagnosis and treatment of allergic diseases. METHODS Airborne pollen samples were collected from 2 sites in Incheon and 2 in Seoul fro...

Cochliophilin A (5-hydroxy-6,7-methylenedioxyflavone, 1), known as a host-specific attractant towards the zoospores of Aphanomyces cochlioides, a cause of root rot and damping-off diseases of Chenopodiaceae, was found in the Amaranthaceae plant, Celosia cristata, that is susceptible to the pathogen. The content of 1 in Celosia seedlings was quantified as 1.4 microg/g fresh weight. A new isoflav...

The importance of Amaranthus retroflexus pollen in causing respiratory allergy has been well ascertained in many countries including Iran with a high positive rate (69%) among Iranian allergic patients. The aim of the present study is to identify the allergenic properties of A. retroflexus pollen. Sixteen patients with allergy to A. retroflexus pollen were selected for the study. The antigenic ...
