Cypress pollen represents the primary cause of respiratory allergies in Mediterranean areas. Patients allergic to Cupressus sempervirens pollen (Cups) (CPA) can be discriminated on the basis of the immunoglobulin E (IgE) binding to a basic 14 kDa protein (BP14) or to high-molecular-weight (HMW) glycoproteins only. Specific IgE repertoires of two differentially exposed CPA cohorts, French and It...

Pollenopyrroside A and pollenopyrroside B, novel pyrrole ketohexoside derivatives, were isolated from the extract of Bee-collected Brassica campestris pollen. Their structures were elucidated by spectroscopic analysis (UV, IR, MS, NMR and X-ray) and chemical evidence. Pollenopyrrosides A and B represent a novel carbon skeleton with a six-six and five-six member dioxaspirocycle bearing nitrogen ...

Saffron (Zaaferan), botanical name Crocus sativus, is the most expensive spice in the world. It is derived from the dried stigma and pistil of the purple saffron crocus flowers. Iran is the largest saffron producer accounting for more than 80% of the world's production. Saffron contains an aeroallergen that causes reactive respiratory allergic reactions in atopic subjects. IgG antibody to aller...

BACKGROUND a new range of allergy vaccines has been developed by the introduction of a relatively new Th1-inducing adjuvant known as 3-deacylated monophosphoryl lipid A (MPL). MPL adjuvant is of natural origin, derived from the lipopolysaccharide of Salmonella minnesota R595. This adjuvant is incorporated in a glutaraldehyde-modified pollen extract adsorbed to L-tyrosine (Pollinex Quattro). A m...

BACKGROUND AND OBJECTIVE Pollen from Japanese hop, Humulusjaponicus, is a major cause of pollinosis in Korea. Profilin (15 kDa) from Humulus scandens has been associated with strong allergenicity in allergic Chinese patients. Profilin has also been detected in pollen extract from Korean Japanese hop by proteomic analysis and immunoglobulin (Ig) E immunoblotting. However, the allergenicity of al...

Cannabis sativa L. is one of the oldest plants known in medicine and one that has been most studied with respect to its phytochemistry (Turner et al., 1980). Currently, a total of 483 constituents have been identified in cannabis of which 66 are cannabinoids (Ross et al., 1995). About 20 flavonoids have been reported to be present in the cannabis plant as aglycones or as conjugated O-glycosides...
