Agarose/κ-carrageenan-based hydrogel film enriched with natural plant extracts for the treatment of cutaneous wounds.

Abstract Hydrogels for complex and chronic wound dressings must be conformable, absorb and retain wound exudates and maintain hydration. They can incorporate and release bioactive molecules that can accelerate the healing process. Wound dressings have to be in contact with the wound and epidermis, even for long periods, without causing adverse effects. Hydrogel dressing formulations based on biopolymers derived from terrestrial or marine flora can be relatively inexpensive and well tolerated. In the present article hydrogel films composed by agarose (1.0 wt%), κ-carrageenan at three different concentrations (0.5, 1.0 and 1.5 wt%) and glycerol (3.0 wt%) were prepared without recourse to cros…

Analysis of the epiphytic bryophyte diversity of Sicily

Sicilian epiphytic bryophyte diversity, based on literature and unpublished data, is assessed both quantitatively and qualitatively. The total number of taxa found on trees or shrubs is 133 (116 mosses and 17 liverworts). Among them, 38 are customary epiphytic, 21 cortico-saxicolous, 13 are indifferent and 61 occasionally epiphytic taxa. The most represented families are Orthotrichaceae (19.1%), which consists above all of several typically corticicolous species, Pottiaceae (19.1%) and Brachytheciaceae (12.6%) which both include many taxa that mainly colonize rock or ground substrates. From the chorological point of view, temperate taxa (33.8%) prevail, followed by oceanic-Mediterranean tax…

Informazione floristica e qualità ambientale: analisi delle brioflore di alcune aree verdi dello spazio urbano di Palermo

The results of a study on the bryofloras of three historical gardens (Villa Giulia, Parco d'Orléans and Giardino Garibaldi) and other four smaller green areas (at Niscemi, Stazione Lolli, Castelnuovo e Kalsa squares) of Palermo are provided. These bryofloras (including 65 taxa) are analyzed from the taxonomic, ecological and chorological point of view and compared with Botanical Garden one. Bryofloristic indices, used as instrument of environmental evaluation, show that bryophyte flora of smaller green areas is more affected by building and traffic density of surrounding zone

Water Extract of Cryphaea heteromalla (Hedw.) D. Mohr Bryophyte as a Natural Powerful Source of Biologically Active Compounds

Bryophytes comprise of the mosses, liverworts, and hornworts. Cryphaea heteromalla, (Hedw.) D. Mohr, is a non-vascular lower plant belonging to mosses group. To the date, the most chemically characterized species belong to the liverworts, while only 3.2% and 8.8% of the species belonging to the mosses and hornworts, respectively, have been investigated. In this work, we present Folin–Ciocalteu and oxygen radical absorbance capacity (ORAC) data related to crude extracts of C. heteromalla obtained by three di erent extraction solvents: pure water (WT), methanol:water (80:20 v/v) (MET), and ethanol:water (80:20 v/v) (ETH). The water extract proved to be the best solvent showing the highest con…
