Taxol is used to treatment of variety cancers including ovarian, breast, lung, head and neck carcinomas and the AIDS-related Karposi’s carcinoma, and was originally obtained from bark of taxus brevifolia. However the amount of extracted taxol from taxus is extremely low and cannot be considered as a suitable commercial source and it has led to studies for finding new sources of Taxol. In 1998, ...

THE postfertilization development of the ovary of the hazel flower results in the formation from the outer integument of the ovule of a thin fibrous seed coat closely adherent to the embryo and from the ovary wall of a hard, lignified pericarp which is quite free from the seed coat at the time when the fruit is ripe. The work recorded in this paper was done on the pericarp of the hazel fruit. T...

BACKGROUND The study tests the hypothesis of a reduction of priming due to tree allergy in patients sensitised to both birch/hazel and grass pollen undergoing an associated preseasonal Sublingual/Injective immunotherapy. METHODS 36 out of 49 bisensitized candidates were pair-matched into 18 case-referent couples. During two years all patients were administered preseasonal grass-SIT and one pa...

Dormancy of hazel (Corylus avellana L.) seeds is alleviated by a chilling treatment during which cytological, hormonal, and biochemical changes occur. Phytic acid and phosphate mobilization have been examined during this treatment. Phytic acid accounted for 0.7% and up to 3.2% of dry weight in axiferous and cotyledonary tissue, respectively. Phytic acid levels in embryonic axes were reduced by ...
