Lipid extract and fatty acid composition of cane molasses and yeasts (Saccharomyces cerevisiae M-300A and Saccharomyces uvarum IZ-1904) grown in molasses medium were determined. In molasses, linoleic acid was found in higher levels (around 42%) and was followed by palmitic, oleic and linolenic acids. The lipid extract varied from 1.02 to 3.13 gkg. In yeasts, the level of lipid extract varied fr...

Pollen allergy is characterized by a T(H)2-biased immune response to pollen-derived allergens. However, pollen-exposed epithelia do not encounter pure allergen but rather a plethora of protein and non-protein substances. We demonstrated that pollen liberate lipids with chemical and functional similarities to leukotriens and prostaglandins--the pollen associated lipid mediators (PALMs). To date,...

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...

The maize (Zea mays) late pollen gene ZmMADS2 belongs to the MIKC type of MADS box transcription factor genes. Here, we report that ZmMADS2, which forms a homodimer in yeast (Saccharomyces cerevisiae), is required for anther dehiscence and pollen maturation. Development of anthers and pollen was arrested at 1 d before dehiscence in transgenic plants expressing the ZmMADS2-cDNA in antisense orie...

Little is known about the levels of exposure to grass pollen in urban environments. We assessed the spatio-temporal variation of grass pollen concentrations and the role of urbanity as a determinant of grass pollen exposure in the Helsinki Metropolitan area. We monitored grass pollen concentrations in 2013 at 16 sites during the peak pollen season by using rotorod-type samplers at the breathing...

BACKGROUND The prevalence of allergic diseases has markedly increased in the last decades. It is therefore important to assess the distribution of airborne pollen, the most important aeroallergen, for allergic disease prevention and control. OBJECTIVE To identify the species and quantity of airborne pollens, and observe their distribution characteristics in Shanghai, using gravitational (Durh...

BACKGROUND Bee pollen has been proposed as a food supplement, but it can be a dangerous food for people with allergy. We study an allergic reaction after ingestion of bee pollen in a 4-year-old boy who had developed rhinitis in the last spring and autumn. METHODS We performed a prick-by-prick test with bee pollen and skin prick tests with the most important local pollens, house dust mites, co...

to study the effect of herb ginger powder on performance, carcass characteristics and blood parameters of broilers used from 192 broiler chicks (ross ) in a completely randomized design with 4 treatments and 4 replicates ( each replicate of 12 chicks ). all treatments, including different levels of ginger powder ratios of 0, 0.5, 1, 1.5 percent respectively called t1, 2t, t3 and t4 that were ad...

pollen grain morphology of 15 taxa of the hedysareae tribe distributed throughout iran was studied using light and electron microscopy to identify major taxonomical characteristics of pollen grains. the pollen grains were tricolpate and tricolporate, prolate and perprolate. the ectocolpi were elongated, shallow or deep, narrowing at the poles. the colpus membrane was covered by large granules. ...
