Jelen tanulmány a Magyarország középső részén levő Duna-ártér fehérnyár-ligeteinek (Senecioni sarracenici-Populetum albae) társulási viszonyait mutatja be 25 cönológiai felvétel alapján. Laza öntéshomok alapkőzeten és nyers öntéstalajon kialakult állományaik az alacsony ártér viszonylag magasabb szintjeit foglalják el. Faji összetételükkel és fejlett cserjeszintjükkel jól elkülöníthetők a mintegy 1–1,5 m-rel mélyebben fekvő, kötött és iszapos talajú, cserjeszint nélküli fűzligetektől (Leucojo aestivi-Salicetum albae), valamint a magasabb ártéri szinten fejlődő tölgy-kőris-szil ligetektől (Scillo vindobonensis-Ulmetum). Aljnövényzetükben egyes – részben szubmontán jellegű – növények is megje­lenhetnek, amelyek az Alföld egyéb tájain ritkák, vagy teljesen hiányoznak: Anemone ranunculoides, Carex remota, Clematis recta, Crataegus × degenii, Crataegus nigra, Epipactis helleborine, Equisetum hyemale, Galanthus nivalis, Lathraea squamaria, Leucojum aestivum, Paris quadrifolia, Scilla vindobonensis, Vitis sylvestris. Az asszociáció a szüntaxonómiai rendszer „Populenion nigro-albae Kevey 2008” alcsoportjába helyezhető.

Mahonia Aquifolium

Endophytic fungi were isolated from five species of broad-leaved evergreen shrubs from 16 sites in western Oregon. Rates of infection were 76% for Mahonia nervosa, 44% for Arctostaphylos uva-ursi, 37% for Gaultheria shallon, 29% for Mahonia aquifolium, and 25% for Umbellularia californica. Incidence of leaf infections by more than one fungal taxon was 20–56%, 72–90% of which had only two infections. Rates of overall infection were higher in samples taken from densely wooded sites than in samples taken from more open sites. A pattern of species dominance is seen where the most common endophyte of a given host is isolated less frequently from other hosts; less commonly isolated endophytes appear to be less host specific. The most commonly isolated endophytes include Phyllosticta pyrolae on A. uva-ursi and G. shallon, Leptothyrium berberidis on M. nervosa, Septogloeum sp. on M. nervosa and U. californica, and Phomopsis sp., predominantly on M. aquifolium, but present on all hosts. Some of the fungi isolated from evergreen shrubs in this study were previously isolated from conifer needles; however, most represent new records.

Control Post

Diabetes is a chronic disease characterized by elevated blood glucose level.Reducing carbohydrate absorption from the intestinal tract is an effective strategy to control post-meal blood glucose level. Inhibition of intestinal α-glucosidase, involved in digestion of carbohydrates, is known as an approach to accomplish this. On the other hand, reduction of α-glucosidase amount is expected to work in the similar manner. However, none of the previousstudy pursues this approach. A convenient assay was developed to evaluate α-glucosidase amount employing Caco-2 cells, the intestinal epithelial cell model reported to express α-glucosidase. Sixty plants were screened and two candidate plants, Calluna vulgaris and Perilla frutescens var. crispa were found to reduce α-glucosidase expression. C. vulgaris extract was subjected to activity guided isolation. Proanthocyanidin was identified as the active principle which was analyzed by thiol decomposition to reveal the components as a mixture ofcatechin, epicatechin, epigallocatechin, and A type procyanidin dimer. The proanthocyanidin suppressed about 30% of α-glucosidase amount evaluated through convenient assay, and suppressed bulk of mRNA expression level of sucrase-isomaltase (SI) at 0.125 mg/mL. Several flavan-3-ol monomers were also tested, and epicatechin gallate and epigallocatechin gallate were found to suppress α-glucosidase amount significantly.
