During the last two decades, various medicinal plants have been studied for their possible antimicrobial activity to discover new antimicrobial agents capable of resolving problems such as the development of drug resistance in pathogenic microorganisms as well as the side effects of some present antibiotics. In this study, the antibacterial activity of methanolic extract of T. pubescens (rich i...

Field studies were conducted to determine the flight response of the twig beetle Pityophthorus pubescens (Marsham) (Coleoptera: Curculionidae: Scolytinae) to the potential aggregation pheromone component, (E)-(+)-pityol, and its racemic form, (E)-(±)-pityol, in different Pinus spp. L. (Pinales: Pinaceae) stands in the Basque Country (Northern Spain). Both (E)-(+)-pityol and (E)-(±)-pityol equal...

Twenty-two species of Elateridae are newly reported for New Brunswick, Canada. Negastrius exiguus (Randall) is removed from the faunal list and Agriotes pubescens Melsheimer is re-instated as a member of the New Brunswick fauna. Agriotes pubescens Melsheimer, Dalopius brevicornis W. J. Brown, Danosoma obtectum (Say) and Megapenthes solitarius Fall are newly reported for the Maritime provinces. ...

BACKGROUND Pterodon pubescens Benth seeds are commercially available in the Brazilian medicinal plant street market. The crude alcoholic extracts of this plant are used in folk medicine as anti-inflammatory, analgesic, and anti-rheumatic preparations. The aim of this study was to evaluate the contribution of geranylgeraniol (C1) and 6alpha, 7beta-dihydroxyvouacapan-17beta-oate methyl ester (C2)...

The extract of Siegesbeckia pubescens herb and its chemical constituents were tested for the ability to inhibit lipopolysaccharide (LPS)-induced nitric oxide (NO) production in BV2 microglia. The methanol extract and the 90% MeOH fraction of S. pubescens effectively attenuated lipopolysaccharide-induced nitric oxide production. Several steps of chromatography yielded eight ent-kaurane diterpene...

Current databases of Phyllostachys pubescens full-length cDNAs (FL-cDNAs) provide a rich source of sequences for the development of potential FL-cDNA simple sequence repeat (SSR) markers. We screened 10,608 P. pubescens cDNAs, discovering 1614 SSRs in 1382 SSR-containing FL-cDNAs. The SSRs were more abundant within transposable elements (TEs) than expressed sequence tags (ESTs) and genome surve...

Background and Objective: The prevalence of Ulcerative Colitis (UC) in most countries has increased and it is necessary to develop new therapeutic options for UC. Siegesbeckia pubescens is a traditional Chinese medicine widely used for the treatment of inflammatory and autoimmune diseases in clinic. The purpose of this study is to evaluate its therapeutic effect against UC. Materials and Method...

The aim of this thesis was to study patterns of reproduction of Betula pendula and B. pubescens coll. along an altitudinal, coastal-inland, gradient in northern Sweden. The altitudinal variation was related to the distribution of the birch taxa along the gradient. Six years field data showed a steep decrease of seed germinability of B. pendula towards its altitudinal range limit in the Scandes ...

Environmental factors alter the impacts of parasitic plants on their hosts. However, there have been no controlled studies on how water availability modulates stem hemiparasites' effects on hosts. A glasshouse experiment was conducted to investigate the association between the Australian native stem hemiparasite Cassytha pubescens and the introduced host Ulex europaeus under high (HW) and low (...

Tree water deficit estimated by measuring water-related changes in stem radius (DeltaW) was compared with tree water deficit estimated from the output of a simple, physiologically reasonable model (DeltaWE), with soil water potential (Psisoil) and atmospheric vapor pressure deficit (VPD) as inputs. Values of DeltaW were determined by monitoring stem radius changes with dendrometers and detrendi...
