| a biomonitoring study: trace metals in algae and molluscs from tyrrhenian coastal areas. | marine organisms were evaluated as possible biomonitors of heavy metal contamination in marine coastal areas. concentrations of cd, cr, cu, pb, and zn were measured in the green algae ulva lactuca l., the brown algae padina pavonica (l.) thivy, the bivalve mollusc mytilus galloprovincialis lamarck, and the two gastropod molluscs monodonta turbinata born and patella cerulea l. collected at six coastal stations in the area of the gulf of gaeta (tyrrhenian sea, central italy). the coastal area of t ... | 2003 | 12865053 |
| metals in molluscs and algae: a north-south tyrrhenian sea baseline. | we develop a 800 km long relative baseline of metal pollution for the tyrrhenian sea, from the north of naples to south of sicily (italy), based on spatio-temporal (1997-2004) concentrations of trace metals in marine organisms and on the bioaccumulative properties of those organisms. the study concerns sites in the gulf of gaeta-formia, near naples, and three islands north, west, and south of sicily: ustica, favignana and linosa. the five metals are: cadmium, chromium, copper, lead, and zinc; th ... | 2010 | 20605327 |
| antimicrobial activities of bacteria associated with the brown alga padina pavonica. | macroalgae belonging to the genus padina are known to produce antibacterial compounds that may inhibit growth of human- and animal pathogens. hitherto, it was unclear whether this antibacterial activity is produced by the macroalga itself or by secondary metabolite producing epiphytic bacteria. here we report antibacterial activities of epiphytic bacteria isolated from padina pavonica (peacocks tail) located on northern coast of tunisia. eighteen isolates were obtained in pure culture and tested ... | 2016 | 27462308 |
| different culture metabolites of the red sea fungus fusarium equiseti optimize the inhibition of hepatitis c virus ns3/4a protease (hcv pr). | the endophytic fungus fusarium equiseti was isolated from the brown alga padina pavonica, collected from the red sea. the fungus was identified by its morphology and 18s rdna. cultivation of this fungal strain in biomalt-peptone medium led to isolation of 12 known metabolites of diketopeprazines and anthraquinones. the organic extract and isolated compounds were screened for their inhibition of hepatitis c virus ns3/4a protease (hcv pr). as a result, the fungal metabolites showed inhibition of h ... | 2016 | 27775589 |
| extracts from two ubiquitous mediterranean plants ameliorate cellular and animal models of neurodegenerative proteinopathies. | a signature feature of age-related neurodegenerative proteinopathies is the misfolding and aggregation of proteins, typically amyloid-β (aβ) in alzheimer's disease (ad) and α-synuclein (α-syn) in parkinson's disease (pd), into soluble oligomeric structures that are highly neurotoxic. cellular and animal models that faithfully replicate the hallmark features of these disorders are being increasing exploited to identify disease-modifying compounds. natural compounds have been identified as a usefu ... | 2017 | 27919712 |
| fatty acids, amino acids, mineral contents, and proximate composition of some brown seaweeds(1). | this study was conducted to create a nutritional database on brown seaweeds and to popularize their consumption and utilization in iran. the fatty acid contents, amino acids profiles, and certain mineral elements composition of some brown seaweeds, padina pavonica (l.) thivy, dictyota dichotoma (huds.) j. v. lamour., and colpomenia sinuosa (mert. ex roth) derbés et solier were determined. total lipid content ranged from 1.46 ± 0.38 to 2.94 ± 0.94 g · 100 g(-1) dry weight (dwt), and the most abun ... | 2012 | 27009718 |
| macroalgae and dgt as indicators of available trace metals in marine coastal waters near a lead-zinc smelter. | the levels of cd, cu, pb, and zn were determined in the commonest species of green, red, and brown algae collected from five coastal sites in south-western sardinia (italy), an area with a long history of mining and smelting. the usefulness of employing enteromorpha sp. and padina pavonica (l.) thivy to monitor metal pollution was evaluated, while diffusive gradients in thin films (dgt) devices were used to measure dissolved metals in seawater. levels of cd and pb were high enough to be of envir ... | 2010 | 19603278 |
| baseline trace metals in seagrass, algae, and mollusks in a southern tyrrhenian ecosystem (linosa island, sicily). | trace elements were analyzed in organisms collected at five sampling stations along coastal areas of linosa island, sicily (southern tyrrhenian sea, italy). concentrations of cd, cr, cu, pb, and zn were measured in posidonia oceanica l. delile tissues, the two brown algae padina pavonica (l.) thivy and cystoseira sp., and the two gastropod mollusks monodonta turbinata born and patella caerulea l. seawater samples were also collected at each site to assess soluble metal concentrations and to gain ... | 2010 | 19458990 |
| arsenosugars and other arsenic compounds in littoral zone algae from the adriatic sea. | in 10 different marine algae from the littoral zone (found between the highest and lowest tide marks on the seashore) arsenic compounds were determined by means of a high-performance liquid chromatography (anion and cation exchange)-uv photochemical digestion-hydride generation-atomic fluorescence spectrometry (hplc-uv-hgafs) system. samples (ceramium sp., cystoseira barbata, enteromorpha sp., fucus virsoides, two different species of gelidium, padina pavonica, polisyphonia sp. and ulva rigida) ... | 2006 | 16289244 |
