Case study #4 : Strait of Sicily - Malta : Western Mediterreanean

The definition of spatial limits for the Strait of Sicily - Malta Case Study have been elaborated considering needs and priorities emerged from the Initial Assessment, as well as existing knowledge on: (i) maritime uses and economic domains; (ii) ecological features; (iii) legal jurisdictions and borders and (iv) transboundary issues. The definition of the case study area’s spatial limits constitute boundaries for the purpose to foster a proper analysis on human uses, ecological processes, synergies and conflicts, governance continuity, and define recommendations to establish appropriated strategies and plans. The boundaries have been drawn according to the scope of the project (e.g. to support the implementation of Maritime Spatial Planning in EU Member States with a concrete cross-border initiative) and the activities to be developed therefore on one hand they are representative of local conditions and policies and, on the other, they take in account potential transboundary and cross-border issues of MSP. The SIMWESTMED case study for Malta is focused on the Malta-Sicily marine waters, bordering the south of Sicily and the north of the Maltese Islands and including part of the continental shelves of Italy and Malta.Grant Agreement: EASME/EMFF/2015/1.2.1.3/02/SI2.742101peer-reviewe

Develop a basin scale analysis/initial assessment strongly MSP oriented for the Western Mediterranean

This Report has been created thanks to the collaboration of all the Member States involved in the SIMWESTMED project (Figure 1) that have been invited to complete the Country Fiche (CF), a document that has leaded to the development of shared knowledge regarding the marine area considered in the project. Thus, the aim of this Report is to entail a collection of information across the European countries of the Western Mediterranean region and the Strait of Sicily, including Malta waters. The Initial Assessment (IA), in fact, provides an initial overview of the area’s characteristics and this report is the harmonized output of all available information including the description of marine environment, maritime activities, key sectoral and socio-economic trends and emerging pressures, legal and transboundary issues, and governance aspects. The assessment uses existing information by organizing them in a comparable way in order to carry out a previous analysis on the main driver and issues that need to be considered for future MSP processes. The IA is based mainly on desk-based reviews, in order to build a shared synthetic view on the Western Mediterranean region, identifying key issues (main activities and priority conservation issues) and data gaps that are synthesized in the following report.peer-reviewe

Sequence-Defined Scaffolding of Peptides on Nucleic Acid Polymers

We have developed a method for the T4 DNA ligase-catalyzed DNA-templated polymerization of 5′-phosphorylated pentanucleotides containing peptide fragments. The polymerization proceeds sequence-specifically to generate DNA-scaffolded peptides in excellent yields. The method has been shown to tolerate peptides ranging from two to eight amino acids in length with a wide variety of functionality. We validated the capabilities of this system in a mock selection for the enrichment of a His-tagged DNA-scaffolded peptide phenotype from a library, which exhibited a 190-fold enrichment after one round of selection. This strategy demonstrates a promising new approach to allowing the generation and <i>in vitro</i> selection of high-affinity reagents based upon single-stranded DNA scaffolding of peptide fragments

Antioxidant and potential anti-inflammatory activity of extracts and formulations of white tea, rose, and witch hazel on primary human dermal fibroblast cells

BACKGROUND: Numerous reports have identified therapeutic roles for plants and their extracts and constituents. The aim of this study was to assess the efficacies of three plant extracts for their potential antioxidant and anti-inflammatory activity in primary human skin fibroblasts. METHODS: Aqueous extracts and formulations of white tea, witch hazel and rose were subjected to assays to measure anti-collagenase, anti-elastase, trolox equivalent and catalase activities. Skin fibroblast cells were employed to determine the effect of each extract/formulation on IL-8 release induced by the addition of hydrogen peroxide. Microscopic examination along with Neutral Red viability testing was employed to ascertain the effects of hydrogen peroxide directly on cell viability. RESULTS: Considerable anti-collagenase, anti-elastase, and antioxidant activities were measured for all extracts apart from the witch hazel distillate which showed no activity in the collagenase assay or in the trolox equivalence assay. All of the extracts and products tested elicited a significant decrease in the amount of IL-8 produced by fibroblast cells compared to the control (p < 0.05). None of the test samples exhibited catalase activity or had a significant effect on the spontaneous secretion of IL-8 in the control cells which was further corroborated with the microscopy results and the Neutral Red viability test. CONCLUSIONS: These data show that the extracts and products tested have a protective effect on fibroblast cells against hydrogen peroxide induced damage. This approach provides a potential method to evaluate the claims made for plant extracts and the products in which these extracts are found

Anti-collagenase, anti-elastase and anti-oxidant activities of extracts from 21 plants

BACKGROUND: Owing to their roles in tissue remodelling in health and disease, several studies have reported investigations on plant extracts as inhibitors of proteinases and as anti-oxidants. METHODS: The anti-ageing and anti-oxidant properties of 23 plant extracts (from 21 plant species) were assessed as anti-elastase and anti-collagenase activities and in selected anti-oxidant assays along with phenolic content. RESULTS: Anti-elastase activities were observed for nine of the extracts with inhibitory activity in the following order: white tea (approximately 89%), cleavers (approximately 58%), burdock root (approximately 51%), bladderwrack (approximately 50%), anise and angelica (approximately 32%). Anti-collagenase activities were exhibited by sixteen plants of which the highest activity was seen in white tea (approximately 87%), green tea (approximately 47%), rose tincture (approximately 41%), and lavender (approximately 31%). Nine plant extracts had activities against both elastase (E) and collagenase (C) and were ranked in the order of white tea (E:89%, C:87%) > bladderwrack (E:50%, C:25%) > cleavers (E:58%, C:7%) > rose tincture (E:22%, C:41%) > green tea (E:10%: C:47%) > rose aqueous (E: 24%, C:26%) > angelica (E:32%, C:17%) > anise (E:32%, C:6%) > pomegranate (E:15%, C:11%).Total phenolic content varied between 0.05 and 0.26 mg gallic acid equivalents (GAE)/mL with the exception of white tea (0.77 mg GAE/mL). For anti-oxidant assessment, the Trolox equivalent anti-oxidant capacity (TEAC) assay revealed activity for all extracts. White tea had the highest activity equivalent to approximately 21 microM Trolox for a 6.25 microg aliquot. In addition, seven extracts exhibited activities = 10 microM Trolox with witch hazel (6.25 microg = 13 microM Trolox) and rose aqueous (6.25 microg = 10 microM Trolox) showing very high activities at low concentrations. A high activity for white tea was also found in the superoxide dismutase (SOD) assay in which it exhibited ~88% inhibition of reduction of nitroblue tetrazolium. High activities were also observed for green tea (86.41%), rose tincture (82.77%), witch hazel (82.05%) and rose aqueous (73.86%). CONCLUSION: From a panel of twenty three plant extracts, some one dozen exhibit high or satisfactory anti-collagenase or anti-elastase activities, with nine having inhibitory activity against both enzymes. These included white tea which was found to have very high phenolic content, along with high TEAC and SOD activities
