The role of light in cold acclimation of Hedera helix L. var. Thorndale appears to differ from that reported for winter annuals. Although light greatly enhances the degree of hardiness attained, cold acclimation is not obligatorily linked to a light requirement. Photoperiods, varying from 8 to 24 hours, received during the cold acclimation period were equally effective in promoting maximum hard...

Materials and Methods ― Fodder and fecal samples were collected from 3 groups of 3 goats, browsing ad lib on fresh leafy Quercus pubescens branches. The 3 groups were made up of: 3 dried-up animals without supplementation; 3 lactating animals, supplemented with a urea-molasses mixture, in a digestibility cage (Meuret, 1988); and 3 lactating animals compelled to eat a pure 0 pubescens die...

Conflict of interests: The authors declare no conflict of interests. andneck. He hadno previous skin disease. He hadworked as a landscape gardener for the previous 2 years, and had been pruning common ivy 2 days before the dermatitis outbreak. Examination showed severe dermatitis on the middle of his thighs down to his lower legs, partly involving the ankles, and on the middle of his upper arms...

Hedera helix L., a member of Araliaceae family, has antiproliferative, cytotoxic, antimicrobial, antifungal, antiprotozoal and anti-inflammatory effects, and is used in cosmetics. The aim of the present study was to investigate the effect of treatment with extracts of leaves and unripened fruits of H. helix on rat prostate cancer cell lines with markedly different metastatic potentials: Mat-LyL...

The permeabilities of amino acids for isolated cuticular membranes of ivy (Hedera helix L.) were measured at different pH. Cuticular permeances were lowest for the zwitterionic form at pH 6, followed by the cationic form at pH 1. Highest permeances were obtained for the anionic form at pH 11. Permeances were not correlated with octanol/water partition coefficients and decreased at a given pH wi...
