| vegetation pattern and heavy metal accumulation at a mine tailing at gyöngyösoroszi, hungary. | vegetation at an abandoned heavy metal bearing mine tailing may have multifunctional roles such as modification of water balance, erosion control and landscape rehabilitation. research on the vegetation of mine tailings can provide useful information on tolerance, accumulation and translocation properties of species potentially applicable at moderately contaminated sites. analyses of the relationship between heavy metal content (pb, zn and cu) and vegetation in a mine tailing were carried out. t ... | 2005 | 15948607 |

| dynamic of plant composition and regeneration following windthrow in a temperate beech forest. | the effects of soil pedoturbation (i.e., pit and mound microtopography, pm) on development of herbaceous plant species and woody species regeneration were examined in a temperate beech forest (fagus orientalis lipsky) in northern iran. we recorded the vegetation in 20 pairs of disturbed and adjacent undisturbed plots and established a chronosequence of pm ages to study the effect of time since microsite formation on cover percent of herbaceous plants and woody regeneration status. according to o ... | 2014 | 27379260 |
| the influence of rubus idaeus and rubus caesius leaf extracts on platelet aggregation in whole blood. cross-talk of platelets and neutrophils. | recently, polyphenols have gained attention as potential natural cardioprotective therapeutics, due to their antiplatelet, anti-inflammatory and anticoagulant activity. species belonging to the genus rubus sp. have been reported to be a source of polyphenolic compounds with antioxidative proprieties and beneficial biological activities. this study investigates the effects of leaf extracts obtained from red raspberry (rubus idaeus l.) and european dewberry (rubus caesius l.) on the reactivity of ... | 2016 | 26836594 |
| rapd-based method for the quality control of mediterranean oregano and its contribution to pharmacognostic techniques. | a pharmacognostic survey of 84 commercial samples of mediterranean oregano, obtained from wholesale traders between 2001 and 2007, pinpointed the presence of extraneous plant material in 90.5% of the samples. in 59% of them extraneous material of plant origin was above 20%. two major groups of botanical foreign matter were identified: oregano-like flavored plants ( satureja montana l., origanum majorana l.) and plants lacking a clearly detectable essential oil profile ( rubus sp., cistus incanus ... | 2009 | 19216531 |
