rivation of blood flow to the brain, results in the insidious delayed degeneration of specific vulnerable neurons within the hippocampus. Among hippocampal neurons, pyramidal cells of the hippocampal CA1 region are most vulnerable to cerebral ischemia. Death of the CA1 pyramidal cells following cerebral ischemia causes a variety of neurological dysfunction such as depression and memory deficits...

BACKGROUND AND AIMS Floral symmetry presents two main states in angiosperms, namely polysymmetry and monosymmetry. Monosymmetry is thought to have evolved several times independently from polysymmetry, possibly in co-adaptation with specialized pollinators. Monosymmetry commonly refers to the perianth, even though associated androecium modifications have been reported. The evolution of perianth...

The Berberidaceae family of shrubs has about 20 species present in Chile; however, the Calafate (Berberis microphylla) native to Chilean and Argentinean Patagonia, is most widely distributed. objective this study was compare antioxidant capacity collected at different locations southern Chile, specifically Aysén Magallanes.

Berberis is an important genus and well known in the Indian as well as European systems of traditional medicine. It is used since ancient times for curing eye disease, fever, jaundice, rheumatism, vomiting during pregnancy, kidney and gall balder stones and various other ailments due to the presence of biologically active alkaloid berberine. Action of the root extracts of few species are believ...

Relative allocation to female and male function in hermaphroditic species often departs from strict equisexuality. Increased femaleness with plant size in animal-pollinated species has been proposed in theory and demonstrated in empirical studies. However, such size-dependent sex allocation (SDS) has not been observed in some insect-pollinated species, throwing doubt on the generalization of SD...
