severe allergic reactions during specific immunotherapy may occur in the treatment of hymenoptera sting allergy. the objective of the present study was to examine the characteristics of allergic reactions during specific immunotherapy in patients with allergy towards hymenoptera venom in the iranian population. a prospective study was performed using the clinical reports of 27 patients with ana...

the laelapid mite, gaeolaelapsaculeifer (canestrini) is widespread in soil habitats and feeds on different small arthropods, fungi and nematodes. the development and fecundity of g. aculeifer feeding on rhizoglyphus echinopus (fumouze & robin) as prey was studied at eight different constant temperatures which include: 16, 17.5, 20, 22.5, 25, 27.5, 30 and 32.5 ºc, with relative humidity of 6...

the sub-lethal effect of metarhizium anisopliae and imidacloprid as well as combination of the two control agents was examined on life table parameters of myzus persicae on different cultivars of canola under laboratory condition at 25 ± 1 ºc, 85% rh and photoperiod of 16l: 8d. the offspring resulting from fungus-infested adults were placed onto leaf discs in petri dishes separately to record t...

background and aims: life expectancy is one of the most important indicators of health and well-being of a society. since it is claimed that in aran-bidgol region, center of iran, life expectancy is higher than the average of the country, this study was designed. methods: during a cross-sectional study, population and mortality data of kashan university of medical sciences (kaums) in 2011 were ...

Understanding biodiversity distribution is a primary goal of community ecology. At a landscape scale, bee communities are affected by habitat composition, anthropogenic land use, and fragmentation. However, little information is available on local-scale spatial distribution of bee communities within habitats that are uniform at the landscape scale. We studied a bee community along with floral a...

This paper is based on swarm intelligence and chaotic dynamics for learning. We address this issue by considering the problem of path planning for mobile robots. Autonomous systems assume intelligent behavior with ability of dealing in complex and changing environments. Path planning problem, which can be studied as an optimization problem, seems to be of high importance for arising of intellig...

This report deals with a father and his son who developed acute renal failure following multiple bee stings. The renal lesion in these patients appears to be due to rhabdomyolysis caused by the bee venom. The other mechanisms are also discussed. The need for clinicians to be aware of acute renal failure as a complication of bee stings is stressed.

Honey bee colonies are highly dependent upon the availability of floral resources from which they get the nutrients (notably pollen) necessary to their development and survival. However, foraging areas are currently affected by the intensification of agriculture and landscape alteration. Bees are therefore confronted to disparities in time and space of floral resource abundance, type and divers...

Commercial beekeepers in many locations are experiencing increased annual colony losses of honey bees (Apis mellifera), but the causes, including role agrochemicals losses, remain unclear. In this study, we investigated effects chronic consumption pollen containing a widely-used fungicide (Pristine®), known to inhibit bee mitochondria vitro, which has recently been shown reduce worker lifespan ...
