Long‐term falls in antibodies to dust mite and pollen allergens in patients with asthma or hay fever

Clinical & Experimental Allergy, 1983
Summary‘Spontaneous’ improvement in, or alteration of, allergic symptoms is a common occurrence, and the immunological basis is of interest in attempts to develop effective specific therapy. In the present study we measured levels of serum antibodies to Dermatophagoides pteronyssinus in patients diagnosed as having house‐dust‐allergic asthma up to 40 ...

Analysis of airborne pollen fall in Edirne, Turkey

2004
In the atmosphere of Edime 12 691 pollen grains belonging to 42 taxa were identified by using of Durham sampler in 2000 and 2001. A total of 6 189 pollen grains per cm(2) were recorded in 2000 and a total of 6 502 pollen grains per cm(2) in 2001. Total pollen grains consisted of 71.81% grains from arboreal plants, 25.88% grains from non-arboreal plants

Manipulating pollen supply in honey bee colonies during the fall does not affect the performance of winter bees

The Canadian Entomologist, 2007
AbstractEach fall, honey bee (Apis mellifera L. (Hymenoptera: Apidae)) colonies in northern temperate regions rear a population of long-lived winter bees that maintains a broodless nest throughout the winter and resumes brood-rearing activities in the spring.

Analysis of Airborne Pollen Fall Tekirdağ Turkey

2010
Objective: Airborne pollen grains are important aeroallergens. When released in sufficient amounts, allergenic pollen may evoke allergic responses in the sensitive patients, leading to allergic rhinitis and asthma. The aim of this study was to determine pollen grains and changes in pollen fall per cm(2) weekly, monthly and annually in the atmosphere of

POLLEN EVIDENCE FOR THE AGE OF THE LILESVILLE GRAVELS: A NEOGENE STRATH TERRACE DEPOSIT FROM THE FALL ZONE OF NORTH CAROLINA, USA

Geological Society of America Abstracts with Programs, 2017
In the vicinity of Lilesville, NC, there are extensive, previously undated, quartz-rich, coarse-grained gravel deposits found capping interfluves in the dissected Piedmont landscape of the Fall Zone. These deposits unconformably overlie the Late Paleozoic Lilesville pluton and its saprolite.

The cross-reactivity of IgE antibodies with pollen allergens. II. Analyses of various species of ragweed and other fall weed pollens.

The Journal of allergy and clinical immunology, 1976
Although the antigenic composition of short ragweed pollen has been extensively investigated, very few studies have analyzed the allergenic cross-reactivity among various types of ragweed pollens. Using a serum pool from patients sensitive to short ragweed, we studied the cross-reactivity of IgE antibodies to six ragweeds by the radioallergosorbent ...

AIRBORNE POLLEN FALL IN KOYCEGIZ SPECIALLY PROTECTED AREA (SW TURKEY)

2009
Airborne pollen fall in the atmosphere of Koycegiz was investigated in 2003 and 2004 using, a Durham sampler. Pollen grains per cm(2) were weekly calculated. During the two years, 17,470 pollen grains/cm(2) (9,061 in 2003 and 8,409 in 2004) belonging to 41 taxa as well as unidentified pollen grains were recorded. Thirteen plant taxa take a place, which

Elliptical pollen corona from North American boreal paper birch trees (Betula papyrifera): strong fall orientations for near-spherical particles

Applied Optics, 2011
It has only recently been realized that solar corona can be generated by dispersions of tree pollen grains suspended in the atmosphere, and these studies have come almost exclusively from Scandinavia. Using corona photographic and surface pollen analyses, it is shown here that paper birch trees in the interior of Alaska regularly generate solar corona ...
