Pollen allergies are an important and relevant question in the personal life of millions people. They well characterized on genomic proteomic level allergens per se medicinal level, but very few information exists about natural variability background pollen allergen transcription patterns. Here, expression Bet v 1, 2, Cor a 1 2 were performed. Both analysed species, Betulla verrucosa as Corylus...

a new cyclic diarylheptanoid namely alnuheptanoid b (3), along with four known cyclic diarylheptanoids: myricanone (1), (+)-s-myricanol (2), myricanone 5-o--d-glucopyranoside (4), and (+)-s-myricanol 5-o--d-glucopyranoside (5) were isolated from the etoac fraction of alnus japonica steud (family: betulaceae) stem bark. their structures were established by different spectroscopic analyses, as ...

Serum IgE assay is a mainstay step in the allergy work up. Allergenic extracts and molecular components are available at present. This real life study compared the serum specific IgE levels against allergenic extracts with allergenic molecules in patients allergic to Parietaria, Betulaceae, and mites. This retrospective real life study included 489 subjects with respiratory allergy. Inclusion c...

Filbertworm, Cydia latiferreana (Walsingham) (Lepidoptera: Tortricidae), is a key insect pest associated with hazelnuts, Corylus avellana L. (Fagales: Betulaceae), in North America. This study investigated the feasibility of entomopathogenic nematodes as an alternative strategy for filbertworm control. Laboratory and field experiments were conducted between October 2007 and May 2008 in Benton C...
