Aromatic plant species present in the natural Park of Tuscany Archipelago are used as flavoring agents and spices, as dietary supplements and in cosmetics and aromatherapy. The plants are usually collected from wild stands, inducing a depletion of the natural habitat. Therefore, micropropagation of these aromatic plants can play a role in the protection of the natural ecosystem, can guarantee a...

indian meal moth, plodia interpunctella hubner is one of the most important stored-product insects that are controlled by fumigants. however, the use of plant essential oils and their constituents may have the advantage over conventional fumigants in terms of low mammalian toxicity and can be used as alternatives to conventional fumigants. therefore, in this research, repellent activity of 18 p...

A new isoflavone (1) isolated from the roots of Flemingia strobilifera (L) R. Br. was identified as 5,7,4'-trihydroxy 8,2',5'-tri(3-methylbut-2-enyl)isoflavone along with the known phytoconstituents: 5,7,2',4'-tetrahydroxyisoflavone (2), 5,7,4'-trihydroxyisoflavone (3) and beta-sitosterol (4). Structure assignments were performed on the basis of spectroscopic data including homo- and heteronucl...

An r l -system is an r-uniform hypergraph in which every set of l vertices lies in at most one edge. Let mk r l be the minimum number of edges in an r l -system that is not k-colorable. Using probabilistic techniques, we prove that ar l kr−1 ln k l/ l−1 ≤ mk r l ≤ br l kr−1 ln k l/ l−1 where br l is explicitly defined and ar l is sufficiently small. We also give a different argument proving (fo...

BACKGROUND Skin flaps are commonly used in soft-tissue reconstruction; however, necrosis can be a frequent complication. Several systemic and local agents have been used in attempts to improve skin flap survival, but none that can prevent flap necrosis have been identified. AIMS This study aims to determine whether the use of systemic Rosmarinus officinalis (R. officinalis) extract can preven...

Polypeptide assemblies cross-linked by S-S bonds (molecular mass>200 kDa) and single polypeptides folded with internal S-S cross-links (<41 kDa) have been detected by SDS/PAGE in particulate membranes and soluble extracts of developing cotyledons of nasturtium (Tropaeolum majus L.). When first prepared from fruit homogenates, these polypeptides were found to bind reversibly to UDP-Gal (labelled...
