Top ten priorities for global saltmarsh restoration, conservation and ecosystem service research.

Coastal saltmarshes provide globally important ecosystem services including 'blue carbon' sequestration, flood protection, pollutant remediation, habitat provision and cultural value. Large portions of marshes have been lost or fragmented as a result of land reclamation, embankment construction, and pollution. Sea level rise threatens marsh survival by blocking landward migration where coastlines have been developed.

The evolution of ocean literacy: A new framework for the United Nations Ocean Decade and beyond.

First introduced in the early 2000s, the concept of ocean literacy has evolved in recent years, not least since its inclusion as a mechanism for change within the United Nations Ocean Decade's goals. Building on early definitions of ocean literacy, there has been increasing recognition of a range of additional dimensions which contribute to an individual or collective sense of 'ocean literacy'. Drawing on existing research, and parallel and supporting concepts, e.

Oil and gas infrastructure decommissioning in marine protected areas: System complexity, analysis and challenges.

Many offshore oil and gas production facilities are nearing the end of their operational life, with decommissioning now becoming a global challenge. The compatibility of decommissioning operations to marine protected areas (MPAs) creates further challenges. The recently-developed DAPSI(W)R(M) problem structuring framework (covering Drivers, Activities, Pressures, State changes, Impacts (on Welfare) and Responses (as Measures)) was applied here to interrogate the complexity of decommissioning oil and gas infrastructure within MPAs, with outputs feeding into the development of a novel database tool for Screening Potential Impacts of Decommissioning Activities (SPIDA).

"And DPSIR begat DAPSI(W)R(M)!" - A unifying framework for marine environmental management.

The marine environment is a complex system formed by interactions between ecological structure and functioning, physico-chemical processes and socio-economic systems. An increase in competing marine uses and users requires a holistic approach to marine management which considers the environmental, economic and societal impacts of all activities. If managed sustainably, the marine environment will deliver a range of ecosystem services which lead to benefits for society.

Renewables-to-reefs? - Decommissioning options for the offshore wind power industry.

The offshore wind power industry is relatively new but increasing globally, hence it is important that the whole life-cycle is managed. The construction-operation-decommissioning cycle is likely to take 20-30 years and whilst decommissioning may not be undertaken for many years, its management needs to be addressed in both current and future marine management regimes. This can be defined within a Drivers-Activities-Pressures-State Changes-Impacts (on human Welfare)-Responses framework.

Coastal Zone Ecosystem Services: from science to values and decision making; a case study.

This research is concerned with the following environmental research questions: socio-ecological system complexity, especially when valuing ecosystem services; ecosystems stock and services flow sustainability and valuation; the incorporation of scale issues when valuing ecosystem services; and the integration of knowledge from diverse disciplines for governance and decision making. In this case study, we focused on ecosystem services that can be jointly supplied but independently valued in economic terms: healthy climate (via carbon sequestration and storage), food (via fisheries production in nursery grounds), and nature recreation (nature watching and enjoyment). We also explored the issue of ecosystem stock and services flow, and we provide recommendations on how to value stock and flows of ecosystem services via accounting and economic values respectively.

Can the benefits of physical seabed restoration justify the costs? An assessment of a disused aggregate extraction site off the Thames Estuary, UK.

Physical and biological seabed impacts can persist long after the cessation of marine aggregate dredging. Whilst small-scale experimental studies have shown that it may be possible to mitigate such impacts, it is unclear whether the costs of restoration are justified on an industrial scale. Here we explore this question using a case study off the Thames Estuary, UK.

What are the costs and benefits of biodiversity recovery in a highly polluted estuary?

Biodiversity recovery measures have often been ignored when dealing with the restoration of degraded aquatic systems. Furthermore, biological valuation methods have been applied only spatially in previous studies, and not jointly on a temporal and spatial scale. The intense monitoring efforts carried out in a highly polluted estuary, in northern Spain (Nervión estuary), allowed for the economic valuation of the costs and the biological valuation of the benefits associated with a 21 years sewage scheme application.

Interleukin-1β enhances cartilage-to-cartilage integration.

The failure of cartilages to fuse, particularly in the case of articular cartilage under conditions of repair is due to morphological and structural constraints of the tissue. Factors that impede integration include, non-vascularisation, low cellularity, and proteoglycan in the surrounding extracellular matrix acting as a natural barrier to cellular migration. We hypothesised that brief activation of a catabolic cascade by cytokines followed by culture under anabolic conditions would promote tissue fusion in a ring-disk model of cartilage integration.

Management of the marine environment: integrating ecosystem services and societal benefits with the DPSIR framework in a systems approach.

Ever increasing and diverse use of the marine environment is leading to human-induced changes in marine life, habitats and landscapes, making necessary the development of marine policy that considers all members of the user community and addresses current, multiple, interacting uses. Taking a systems approach incorporating an understanding of The Ecosystem Approach, we integrate the DPSIR framework with ecosystem services and societal benefits, and the focus this gives allows us to create a specific framework for supporting decision making in the marine environment. Based on a linking of these three concepts, we present a set of basic postulates for the management of the marine environment and emphasise that these postulates should hold for marine management to be achieved.

Retargeted adenoviral cancer gene therapy for tumour cells overexpressing epidermal growth factor receptor or urokinase-type plasminogen activator receptor.

We have assessed the ability of bispecific fusion proteins to improve adenovirus-mediated transfer of therapeutic and marker transgenes. We constructed an expression vector that can be easily modified to synthesize a variety of fusion proteins for retargeting adenoviral gene therapy vectors to cell surface markers, which are differentially expressed between normal and cancer cells. Adenoviral transduction can be improved in a number of tumour cell lines which overexpress EGFR (epidermal growth factor receptor) or uPAR (urokinase-type plasminogen activator receptor), but which have only low levels of endogenous hCAR (human coxsackie B and adenovirus receptor) expression.

Enhanced tissue integration during cartilage repair in vitro can be achieved by inhibiting chondrocyte death at the wound edge.

Objective: Experimental wounding of articular cartilage results in cell death at the lesion edge. The objective of this study was to investigate whether inhibition of this cell death results in enhanced integrative cartilage repair.

Methods: Bovine articular cartilage discs (6 mm) were incubated in media containing inhibitors of necrosis (Necrostatin-1, Nec-1) or apoptosis (Z-VAD-FMK, ZVF) before cutting a 3 mm inner core.

An application of contingent valuation and decision tree analysis to water quality improvements.

This paper applies contingent valuation and decision tree analysis to investigate public preferences for water quality improvements, and in particular reduced eutrophication. Such preferences are important given that the development of EU water quality legislation is imposing significant costs on European economies. Results are reported of a survey undertaken of residents of Arhus County, Denmark for water quality improvements in the Randers Fjord.

Identification, definition and quantification of goods and services provided by marine biodiversity: implications for the ecosystem approach.

This paper identifies and defines ecosystem goods and services provided by marine biodiversity. Case studies have been used to provide an insight into the practical issues associated with the assessment of marine ecosystem goods and services at specific locations. The aim of this research was to validate the definitions of goods and services, and to identify knowledge gaps and likely difficulties of quantifying the goods and services.

An initial economic evaluation of water quality improvements in the Randers Fjord, Denmark.

Eutrophication of estuarine and coastal waters has only been recognised as a potential problem since the early 1980s. This problem is being addressed by the European Union through the implementation of recent water quality legislation, which also calls for an economic analysis relating to its implementation. This paper examines the benefits and costs of reduced eutrophication of the Randers Fjord in Denmark, with a primary focus on assessing individual preferences for water quality improvements, using a contingent valuation survey approach.

[Acute phase reaction and immunocompetence in sepsis and SIRS].

The incidence of sepsis and SIRS, respectively is still rising. Mortality is 40 to 70% and, thus, remains very high in spite of major advances in intensive care medicine. Numerous experimental data have helped to explain isolated aspects of the pathophysiology of these disease states but the complex patho-mechanism remains to be elucidated.

Growth inhibition by the muscarinic M(3) acetylcholine receptor: evidence for p21(Cip1/Waf1) involvement in G(1) arrest.

We have assessed the growth response of Chinese-hamster ovary (CHO) cells to activation of recombinantly expressed G-protein-coupled muscarinic M(2) or M(3) acetylcholine receptors (AChRs). We show that activation of these receptors leads to divergent growth responses: M(2) AChR activation causes an increase in DNA synthesis, whereas M(3) AChR activation causes a dramatic decrease in DNA synthesis. We have characterized the M(3) AChR-mediated growth inhibition and show that it involves a G(1) phase cell-cycle arrest.

The role of tumor necrosis factor in the development of multiple organ failure in a murine model.

Objective: To elucidate the role of tumor necrosis factor (TNF) in the development of multiple organ dysfunction syndrome (MODS) after zymosan-induced peritonitis in mice.

Design: Prospective controlled laboratory study on zymosan-induced generalized inflammation in mice. Over < or =28 days, a single intraperitoneal administration of zymosan induced a three-phase illness in C57BL mice, rendering them very ill with MODS-like symptoms from day 7 onward.

Differences in the anti-inflammatory effects of theophylline and pentoxifylline: important for the development of asthma therapy?

Antiasthma drugs are now being re-evaluated for their anti-inflammatory effects. Theophylline is an immunomodulator; however, weak effects and the narrow therapeutic window make it a controversial drug. We compared the immunomodulatory potencies of theophylline with those of the xanthines pentoxifylline (POF) and A802715.

The assessment of recovery in patients after myocardial infarction using three generic quality-of-life measures.

Background: To evaluate the sensitivity to change of three generic quality-of-life measures in patients after myocardial infarction (MI).

Methods: Patients admitted to the Coronary Care Unit of Royal Devon and Exeter Healthcare Trust over a 9-month period were selected on the basis of a first MI and under 80 years of age. Quality of life was assessed 6 weeks and 6 months after MI using the Sickness Impact Profile (SIP), Nottingham Health Profile (NHP), and McMaster Health Inventory Questionnaire (MHIQ).

Anti-Borrelia burgdorferi immunoglobulin seroprevalence in pulmonary sarcoidosis: a negative report.

The aetiology of sarcoidosis is still unknown. An infectious microorganism as causal agent for this disease could not be identified, but high titres of antibodies against Borrelia burgdorferi were detected in Chinese studies implying a causality with this disease. These findings, however, could not be reproduced by other researchers.

Replication of IFDO on a chemically defined medium.

An agar or liquid medium containing haemoglobin, high density horse lipoprotein, trypsin, Tween 80, phosphate buffer, CaCl(2), glucose, glutamic acid and NaCl supported growth of ileal fluid dependent organism (IFDO). Glucose, glutamic acid and NaCl were not essential but enhanced growth. Trace amounts of lipoprotein were sufficient to support growth, and some human sera and serum fractions rich in low density lipoprotein could be substituted for horse lipoprotein.
