From pollen count to pollen potency: the molecular era of aerobiology.
In 1873, Charles Harrison Blackley recognised pollen as the cause of hay fever and ‘‘hay asthma’’ [1]. For the first time, he collected pollen grains with a kite that had a sticky tail and then he counted them. Being affected by seasonal asthma himself, he also performed the first skin prick test on his own arm. Since then, aerobiology (from Greek á r, aēr, ‘‘air’’; bioz, bios, ‘‘life’’; and -l...
متن کاملAntibacterial activity of pollen and propolis extracts
The antimicrobial activities of different concentrations of pollen and propolis extracts were determined against nine food-borne pathogens (Streptococcus salivarius RSHE 605, Listeria monocytogenes NCTC 5348, Staphylococcus aureus ATCC 25923, Salmonella enteritidis ATCC 13076, Staphylococcus pneumoniae ATCC 10015, Escherichia coli ATCC 25922, Klebsiella pneumoniae NCTC 5049, Pseudomonas aerugin...
متن کاملPlant pollen content in the air of Lublin (central-eastern Poland) and risk of pollen allergy.
Pollen monitoring was carried out in Lublin in 2001-2012 by the volumetric method using a Hirst-type spore trap (Lanzoni VPPS 2000). Daily pollen concentrations considerably differed in the particular years. The pollen counts with the biggest variability were observed in the first half of a year when woody plants flowering. The highest annual pollen index were noted for the following taxa: Betu...
متن کاملInteraction Between Air Pollutants and Pollen Grains: The Role on the Rising Trend in Allergy
Asthma and allergic diseases cases have risen in recent decades. Plant pollen is considered as the main aeroallergen causing allergic reactions. According to available data, urban residents experience more respiratory allergies than rural residents mainly due to the interaction between chemical air pollutants and pollen grains. This interaction can occur through several mechanisms; chemical pol...
متن کاملPollen and Pollen Tube Proteomics
Germinated pollen grains form pollen tubes that accomplish rapid polarized growth within female gametophytic tissues in order to deliver the sperm cell to the ovule. This process is essential for successful plant fertilization in vivo. Pollen tubes are considered to be an ideal model system to study tip growth. A more comprehensive understanding of proteins involved in pollen development, germi...
