The negative effects on adult behavior of juvenile undernourishment are well documented in vertebrates, but relatively poorly understood in invertebrates. We examined the effects of larval nutritional stress on the foraging and recruitment behavior of an economically important model invertebrate, the honey bee (Apis mellifera). Pollen, which supplies essential nutrients to developing workers, c...

OBJECTIVE Pollen grains of the Euphorbiaceae family are well known causative agents of respiratory allergies in India, European countries and USA. Mallotus phillipensis belongs to the same family and may have some common allergenic properties. It has thus been evaluated for the first time in Indian population for its pollinosis causing properties. METHODS Pollen antigen of Mallotus phillipens...

BACKGROUND The GA2LEN chamber has been developed as a novel mobile allergen exposure chamber (AEC) allowing standardized multicenter trials in allergy. Hitherto, subjective nasal symptom scores have been the most often used outcome parameter, but in standardized modern trials objective parameters are preferred. Despite its practicability, the objective parameter peak nasal inspiratory flow (PNI...

the importance of amaranthus retroflexus pollen in causing respiratory allergy has been well ascertained in many countries including iran with a high positive rate (69%) among iranian allergic patients. the aim of the present study is to identify the allergenic properties of a. retroflexus pollen. sixteen patients with allergy to a. retroflexus pollen were selected for the study. the antigenic ...

The objective of this study was to determine the effect of diet supplementation with propolis and bee pollen on selected physical, biomechanical and chemical properties of tibial bones in broiler chickens. The experimental materials comprised 384 Ross 308 chickens (four groups, three replications), divided into groups of males and females, and raised to 35 days of age. Control group 1 birds wer...

Self-incompatibility has been studied by using controlled pollination, pollen tube growth and PCR methods in the Iranian almond ‘Mamaei.’. Pollen tube growth and fruit set following self and cross-pollination treatments were evaluated. The percentage of initial and final fruit set was determined for each treatment at 30 and 60 days after controlled pollination. Pollen germination and pollen ...

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...

Title of dissertation: AN ECOLOGICAL RISK ASSESSMENT OF BT TRANSGENIC SWEET CORN ON NON-TARGET INVERTEBRATE COMMUNITIES Robyn Ilene Rose, Doctor of Philosophy, 2005 Dissertation directed by: Professor Galen P. Dively Department of Entomology An ecological risk assessment evaluating potential adverse affects to non-target arthropods is necessary when releasing a novel transgenic crop. Field stud...

Prof. Dr. Wolfgang Remy, Dermatologische Klinik und Poliklinik, der Technischen Universität München, Biedersteiner Strasse 29, D-80802 München (FRG) In an interesting comment, recently published in this journal, Singh and Maibach [1] state that extensive research is still required to maximize iontophoresis for controlled systemic transdermal administration of charged, hydrophilic and large drug...
