Taxonomical and phytogeographycal remarks on Trifolium savianum Guss., a misappreciated species of the Italian flora.

2000

The taxonomic position, chorology and phytosociological role of Trifolium savianum, a misappreciated species of the Italian flora, are examined. The species is closely related to T. uniflorum, E.-Mediterranean element, from which it differs in several morphological features regarding leaves, flowers and fruits. Distinction of the two taxa at the specific level is also supported by their geographical isolation dating back to the end of the Messinian period. From the phytosociological point of view, T. savianum is a member of an orophilous grassland rich in chamaephytes belonging to Plantaginion cupani, alliance of Molinio-Arrhenatheretea. This community is proposed as a new association, name…

Oxygen binding and its allosteric control in hemoglobin of the primitive branchiopod crustacean Triops cancriformis

2007

Branchiopod crustaceans are endowed with extracellular, high-molecular-mass hemoglobins (Hbs), the functional and allosteric properties of which have largely remained obscure. The Hb of the phylogenetically ancient Triops cancriformis (Notostraca) revealed moderate oxygen affinity, cooperativity and pH dependence (Bohr effect) coefficients: P50 = 13.3 mmHg, n50 = 2.3, and ϕ = −0.18, at 20 °C and pH 7.44 in Tris buffer. The in vivo hemolymph pH was 7.52. Bivalent cations increased oxygen affinity, Mg2+ exerting a greater effect than Ca2+. Analysis of cooperative oxygen binding in terms of the nested Monod–Wyman–Changeux (MWC) model revealed an allosteric unit of four oxygen-binding sites and…

Commento all'art. 422 c.p.p.

2008

Il commento analizza l'attività di assunzione delle prove da parte del giudice nell'udienza preliminare, a seguito della riforma della norma operata dalla c.d. Legge Carotti. In particolare, dopo l'analisi sulla disciplina l'attenzione si sofferma sulla compatibilità dell'adempimento con la logica bifasica del sistema processuale.

Phytoestrogens increase the capacity of serum to stimulate prostacyclin release in human endothelial cells

2003

Both the estrogen receptor (ER) alpha and beta isoforms are expressed in the endothelium. The ER beta has been assigned a crucial role in normal vascular wall function. Prostacyclin has been ascribed a beneficial effect on vessel wall physiology. Isoflavones bind with higher affinity to ER beta. We investigated the hypothesis that their administration to postmenopausal women can promote endothelial prostacyclin production.Twenty-five healthy postmenopausal women with mild climacteric symptoms received capsules containing 55 mg/day isoflavones derived from soy and red clover for 6 months. Cultured human umbilical vein endothelial cells (HUVECs) were exposed for 24 h to serum collected before…

Lead concentrations in feathers and blood of common blackbirds (Turdus merula) and in earthworms inhabiting unpolluted and moderately polluted urban …

2006

9 pages; International audience; Despite the dramatic decrease of atmospheric lead (Pb) concentrations in urban areas of most industrialised countries, we hypothesised that urban common blackbirds (Turdus merula) may still be contaminated by Pb concentrations of toxicological concern due to transfer from soil through the food chain. We sampled blackbirds and earthworms, one of their main preys, in Besan?, a middle-size city of Eastern France (where atmospheric Pb concentrations decreased from 0.5 microg/m(3) in 1987 to nearly 0 in 2002) and in a rural reference site. Lead concentrations were determined in the tissues of the different functional groups of earthworms (anecic, epigeous and end…

Cytotoxic glycosides from the roots of Weigela x “Bristol Ruby”

2019

International audience; Seven oleanane-type glycosides were extracted and isolated by various chromatographic methods from the roots of Weigela x "Bristol Ruby" (1-7), six previously undescribed (1-6) and a known one (7). Their structures were assigned by spectroscopic analysis mainly 2D NMR and mass spectrometry (ESIMS). Selected triterpenoid glycosides (1-3, 6, 7) displayed a good cytotoxic activity against a mouse colon cancer cell line CT26.
