Pollen nightmare: elevated airborne pollen levels at night

High airborne pollen concentrations are generally associated with daylight hours when it is sunny and warm and plants release pollen into the air (Alcázar et al. 1999; Dahl et al. 2013). In contrast, cooler nighttime periods are usually considered to be the time of low-allergy risk. This opinion is often reflected in pollen allergy avoidance strategies presented by the media, where the most com...

Airborne and Allergenic Pollen of North America

ing clinical seizures in epileptic patients [2]. In a volume supposedly designed to help physicians elucidate the recognition of pseudoseizures, such misleading oversimplification serves the opposite cause. The patient was better off before his doctor read this book. To be fair, certain chapters are well written and address their topic beautifully (Desai, Lesser, Ehrenberg). The concept of such...

Changes to Airborne Pollen Counts across Europe

A progressive global increase in the burden of allergic diseases has affected the industrialized world over the last half century and has been reported in the literature. The clinical evidence reveals a general increase in both incidence and prevalence of respiratory diseases, such as allergic rhinitis (common hay fever) and asthma. Such phenomena may be related not only to air pollution and ch...

Quantitative DNA Analyses for Airborne Birch Pollen

Birch trees produce large amounts of highly allergenic pollen grains that are distributed by wind and impact human health by causing seasonal hay fever, pollen-related asthma, and other allergic diseases. Traditionally, pollen forecasts are based on conventional microscopic counting techniques that are labor-intensive and limited in the reliable identification of species. Molecular biological t...
