cyclotides are small disulfide-rich proteins that have the unusual feature of a cyclic backbone. cyclotides have a range of interesting biological activities and are found in a variety of tropical plants from the rubiaceae, violaceae, cucurbitaceae and fabaceae families. we have cloned and characterized cyclotides in viola modesta, a viola species native to western asia, which was collected fro...

In order to continue our previous studies on some Viola species from Romania, we have analysed for the first time some active principles from aerial parts of V. declinata Waldst. et Kit. We have performed gravimetric methods for saponins and mucilages, and spectrophotometric determinations and HPLC analysis of carotenoids. We established the content in saponins (4.40%), mucilages (10.26%), and ...

1. We evaluated the potential for three species of deciduous-forest herbs to exploit seasonal periods of direct irradiance. In particular, we investigated the importance of photosynthetic acclimation as a mechanism for shade-tolerant herbs to utilize direct light reaching the forest floor before canopy expansion in the spring and after canopy leaf drop in the autumn. 2. We measured the photosyn...

Lindgren multiple-funnel traps, baited with (-)-cc-pinene and (k)-pityol, captured significant numbers of the weevils, Pissodes afjnis Randall and P. fascia&s LeConte, in a coastal stand of Douglas-fir and western white pine.

Segmentation is an important step in medical image analysis and classification for radiological evaluation or computer aided diagnosis. The CAD (Computer Aided Diagnosis ) of lung CT generally first segment the area of interest (lung) and then analyze the separately obtained area for nodule detection in order to diagnosis the disease. For normal lung, segmentation can be performed by making use...
