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...
متن کاملAllergenic pollen and pollen allergy in Europe.
The allergenic content of the atmosphere varies according to climate, geography and vegetation. Data on the presence and prevalence of allergenic airborne pollens, obtained from both aerobiological studies and allergological investigations, make it possible to design pollen calendars with the approximate flowering period of the plants in the sampling area. In this way, even though pollen produc...
متن کاملThe impacts of climate change and meteorological factors on pollen season indicators of allergenic plant taxa
Pollen respiratory allergies have been increasing in prevalence over the last two decades, partly as the result of the impact of climate change. For many allergenic trees, grass and weed species, increased pollen production and prolonged pollination period result in long-term increased abundance of pollen allergens in the atmosphere; earlier shifts of airborne pollen grains and prolonged exposu...
متن کاملFirst annual register of allergenic pollen in Talca, Chile.
BACKGROUND There are no data on atmospheric pollen in Talca. In the present work, our aim is to describe the amount of pollen grain in the atmosphere of the city of Talca likely to cause pollinosis of its inhabitants. METHODS A volumetric Hirst sampler (Burkard seven-day recording device) was used to study pollen levels. It was placed in the centre of Talca from May 2007 to April 2008. RESU...
متن کاملIdentification of Proteases and Protease Inhibitors in Allergenic and Non-Allergenic Pollen
Pollen is one of the most common causes of allergy worldwide, making the study of their molecular composition crucial for the advancement of allergy research. Despite substantial efforts in this field, it is not yet clear why some plant pollens strongly provoke allergies while others do not. However, proteases and protease inhibitors from allergen sources are known to play an important role in ...
