- Abstract
Today resilience paradigm is shared by both academic and political debates, and it is gradually being implemented into plans, programmes, and project's initiatives. In this context, wine regions, particularly those designated as UNESCO sites, show their robustness and vulnerabilities as Socio-Ecological Systems. The climate change impact is increasing the exposure of their aesthetic, cultural, economic, natural values to potential losses and therefore an effective response is required To build resilient strategies, Decision Makers are increasingly considering multidimensional models in planning and assessment processes. This paper continues a research work that develops an integrated evaluation framework constituted by Multicriteria Decision Analysis to calculate a Territorial Resilience Index, a dynamical model to predict future ecological scenarios and scenario building to define a resilient strategy for the Douro territory (Portugal). This paper focuses on scenario building which uses specific tools such as Social Network Analysis to identify and investigate the relationships between real actors and stakeholders, Wilson matrix to assess the degree of uncertainty and relevance of the strategies identified by a panel of specialists, and consistency matrix to evaluate the strategies consistency in achieving the Sustainable Development Goals and UNESCO requirements. The obtained protocol of guidelines and recommendations can support Decision Makers in the design of sustainable and resilient transformation, thereby assisting in the preservation of the UNESCO site., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2022 Elsevier B.V.

- Abstract
This paper aims to assess the territorial resilience of a socio-ecological system through an innovative integrated evaluation framework to aid the decision-making process in the planning of transformation scenarios. This framework employs a set of resilience indicators through a Multicriteria Decision Analysis (MCDA) coupled with a Lotka-Volterra mathematical model of cooperative type. The set of indicators aims to calculate a composite index of Territorial Resilience (TRI), whereas the mathematical model is an extension of an existing model, aimed to predict possible long-time scenarios. The proposed operational framework for rural and vineyard landscapes aims to bridge the existing gap between territorial resilience theory and practice, with an innovative Decision Support System able to assist Decision Makers and territory planners in the planning and management of resilient territorial systems. This integrated evaluation framework is applied to a famous wine region in Portugal, the Douro Valley, where Port-wine grows. Such framework, especially in a context of adaptive governance, proves to be a suitable support in the field of landscape and urban planning to evaluate the dynamics of socio-ecological systems and to envision long-term policies and actions., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2020.

- Abstract
Purpose: Our purpose was to assess the ability of electromagnetic transponders (EMTs) to localize and track movements in patients with prostate cancer (PCa) with metallic hip prostheses (MHPs) treated with curative radiation therapy (RT)., Methods and Materials: Data sets of 8 PCa patients with MHPs (3 bilateral and 5 unilateral) treated between 2016 and 2018 with RT and EMT tracking were retrospectively assessed. The distances between the 3 EMTs (apex to left, left to right, right to apex) and the isocenter were calculated both on planning computed tomography (CT) and cone beam CT (CBCT) at the first treatment fraction and compared with data reported by Calypso. EMT position and treatment interruptions triggered by Calypso were analyzed for all evaluable treatment fractions (n = 120). Localization accuracy was quantified by recording the geometric residual value (expected limit ≤0.2 cm) at the RT setup., Results: The Calypso system was able to localize and track prostate position without any detectable interference from MHP. For every treatment fraction, the agreement between the CBCT images and Calypso guidance was optimal, with EMTs always within the defined tolerance (ie, CT-Calypso or CBCT-Calypso measured differences in inter-EMT distances within 0.3 cm). EMT to isocenter distances measured by Calypso reproduced CT data and were confirmed on CBCT scans. During RT, the EMT centroid exceeded the threshold 24 times (20% of all fractions): 5 times in the left-right, 15 times in the anteroposterior, and 4 times in the superoinferior directions. The largest motions recorded were in the anteroposterior axis: 0.6 cm anteriorly and 0.5 cm posteriorly in patients with unilateral and bilateral MHP, respectively., Conclusions: Our study represents the first clinical experience assessing the localization and tracking accuracy of Calypso EMTs during curative RT of patients with PCa with unilateral or bilateral MHP., (Copyright © 2020 American Society for Radiation Oncology.

- Abstract
The effect of the chronic anthropogenic disturbance in a coastal area of the SW-Atlantic was tested through a multimetric-approach. This study integrates environmental variables, biotic indices of environmental quality, and changes in alpha and beta diversity. The outfall site showed high percentages of organic matter, silt and clay in sediment and high concentration of Enterococcus in seawater. The invasive polychaete Boccardia proboscidea dominated the outfall site, while the ecosystem engineer Brachidontes rodriguezii dominated the non-impacted sites. Regarding partitioning of beta diversity the species loss (nestedness) at outfall site would be the process that drives the patterns found. Moreover, outfall site presented the lowest environmental health values in both spring and autumn. This community-level integrated analysis provides useful tools to consider when making decisions regarding coastal management., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2020 Elsevier Ltd.

- Abstract
Papillary tumor of the pineal region (PTPR) is a rare neuroepithelial brain tumor, characterized by a high risk of local recurrence (greater than 70 % at 6 years). The aim of our study was to review the available literature on radiotherapy for PTPR in order to evaluate timings, schedules, outcomes and toxicities of this treatment modality. In our review, 72.4 % (84) of the patients diagnosed with PTPR received radiation therapy. There is heterogeneity in the dose prescription, ranging from 45 Gy (25 × 1.8 Gy) to 60 Gy (30 × 2 Gy) for 3D Conformal Radiation Therapy and from 12 Gy to 36 Gy for Stereotactic Radiosurgery. Being considered as a grade II or III tumor, PTPR should receive higher total radiation dose in the adjuvant setting. Our analysis showed a very limited treatment-related toxicity with an expected 10-y OS of 72.5 %. At 5-years from the diagnosis, about 60 % of the patients experienced a local recurrence, whereas at 10 years the rate is higher than 80 %. In the literature, conflicting data about radiotherapy for PTPR are reported, in particular regarding disease progression. Although radiotherapy represents a fundamental treatment in the management of PTPR, prospective studies are required to better define its impact on overall survival and progression-free survival., Competing Interests: Declaration of Competing Interest All authors certify that they have no affiliations with or involvement in any organization or entity with any financial interest (such as honoraria; educational grants; participation in speakers' bureaus; membership, employment, consultancies, stock ownership, or other equity interest; and expert testimony or patent-licensing arrangements), or non-financial interest (such as personal or professional relationships, affiliations, knowledge or beliefs) in the subject matter or materials discussed in this manuscript., (Copyright © 2019 Elsevier B.V.

- Abstract
The sewage pollution impact over coastal environment represents one of the main reasons explaining the deterioration of marine coastal ecosystems around the globe. This paper aims to detect promptly a putative sewage pollution impact in a Southwestern Atlantic coastal area of Argentina as well as to identify a straightforward way for monitoring, based on the relative abundance coverage of the intertidal epilithic taxa. Four sampling sites were distributed at increased distances from the sewage outfall where the cover of individual epilithic species was visually estimated. The surrounded outfall area (i.e. outfall site) resulted polluted with high percentages of organic matter in sediment and Enterococcus concentration in seawater. The structure of the community showed a remarkable difference between the polluted site (outfall site) and the unpolluted sites. The polychaete Boccardia proboscidea dominated the outfall site with variable abundances of the green algae Ulva sp. during the period of study, decreasing the diversity of the community, while the mussel Brachidontes rodriguezii and variable abundances of several algae species dominated the unpolluted sites. The monitoring of the benthic community represents an effective, non-destructive, relative inexpensive and rapid method to assess the health of the coastal environment in the study area. The large abundance of B. proboscidea along with the absence of B. rodriguezii individuals at <300m to the sewage outfall discharge allowed the success of this classical monitoring method in a temperate marine-coastal ecosystem with certain gradient of pollution., (Copyright © 2018 Elsevier B.V.

- Abstract
Background: In the postprandial state, insulin regulates metabolic and cardiovascular responses. In insulin resistance, the insulin action is impaired at both levels. However, postprandial hemodynamic responses are poorly characterized in this setting., Objective: We investigated fasting and postprandial cardiac and vascular hemodynamic responses in subjects with and without insulin resistance., Design: Sixty-six atherosclerosis-free, healthy volunteers were studied in a fasted state and ≤180 min after ingestion of a mixed meal. The insulin sensitivity index was determined by using a minimal model analysis; hemodynamic response was monitored by using continuous impedance cardiography that allowed a reliable beat-to-beat noninvasive evaluation of stroke volume, cardiac contractility, and several derived variables., Results: Subjects were divided into insulin-resistant (IR; n = 33) and insulin-sensitive (IS; n = 33) groups. After fasting, IR subjects had significantly higher values of systolic and diastolic blood pressures and the systemic vascular resistance index (SVRI) than did IS subjects. In the postprandial state, acute vasodilatation was comparable and synchronous (at 30 min) in IR and IS subjects (P = 0.209), but subsequent vascular tone recovery (30-180 min) was significantly impaired in IR subjects (P = 0.018), even after adjustment for age and sex (P = 0.031). Hemodynamic dysregulation was directly correlated with metabolic disturbances in the postprandial state. In basal and postprandial states, hemodynamic variables related to cardiac function were not significantly different in IR and IS subjects., Conclusions: IR subjects had a worse fasting vascular performance than did IS subjects. In the postprandial phase, insulin resistance was associated with a shorter duration of vasodilatation in the absence of an altered cardiac performance. Peripheral hemodynamic alterations in fasting and postprandial states may have a negative effect on cardiovascular performance in IR patients.

- Abstract
The European Community ban on use of meat and bone meal in ruminant feed, as a consequence of the spread of bovine spongiform encephalopathy in Europe, has prompted a number of investigations about the possibility of detecting animal tissues in feedstuff. In this paper, a study on vertebrate primers, designed in the 16S rRNA gene of mitochondrial DNA, is described. These primers were able to amplify fragments that contained between 234 and 265 bp. The fragments were specific for bovine, porcine, goat, sheep, horse, rabbit, chicken, trout, and European pilchard and were confirmed by sequence analysis amplicons. The primers were used in a PCR assay applied to five samples of meat and blood meals of different species and subjected to severe rendering treatments (134.4 to 141.9 degrees C and 3.03 to 4.03 bar for 24 min). The presence of vertebrate tissues was detected in all samples. The assay proved to be rapid and sensitive (detection limit 0.0625%). It can be used as a routine method to detect animal-derived ingredients in animal feedstuff.

- Abstract
A duplex polymerase chain reaction (PCR) was developed to identify the milk of bovine and buffalo species in cheese products, particularly in mozzarella cheese, a typical Italian cheese made from buffalo's milk. Two sets of primers were designed on the basis of the alignment of the sequence codifying mitochondrial cyt b available in the GenBank database. The primers proved to be species-specific, giving rise to 279-bp (bovine) and 192-bp (buffalo) amplified fragments. Since the amplification conditions for bovine and buffalo primers were identical, a duplex PCR was successfully applied to identify the two species in a single reaction step. This technique, when used to test cheese products from the retail trade, allowed the detection of partial or even total substitution of cow's milk for buffalo's milk, in some cases in samples of cheese misleadingly labeled "pure buffalo" mozzarella.
