Let’s Do It for Real: Making the Ecosystem Service Concept Operational in Regional Planning for Climate Change Adaptation

The application of ecosystem service (ES) knowledge to planning processes and decision-making can lead to more effective climate change adaptation. Despite the increased attention given to the ES concept, its degree of integration and use in spatial planning processes are still below the expectations of those who are promoting this concept. Barriers hindering its operationalisation cover a span of aspects ranging from theoretical to procedural and methodological issues. Overall, there is a general lack of guidance on how and at what point ES knowledge should be integrated into planning processes. This study aims to promote the inclusion of ES knowledge into spatial planning practices and decision-making processes to enhance climate change adaptation. A replicable GIS-based methodology is proposed. First, the potential supply of ESs that can support climate change adaptation (ESCCAs) is defined, mapped, and quantified. Then, a need for an ESCCA supply is identified, and territorial capacities to respond to the expected climate change impacts on natural and socio-economic sectors are assessed. The methodology is applied to the Friuli Venezia Giulia Autonomous Region (Italy) as an illustrative case study. The results reveal that areas with similar geomorphological characteristics tend to respond similarly. Forest ecosystems, inland wetlands and specifically salt marshes can potentially supply a greater variety of ESCCAs. In the case study area, about 62% of the supplied ESCCAs can contribute to reducing the impacts in more than 50% of the impacted sectors. The territory of the study site generally shows good preparedness for expected impacts in most of the analysed sectors; less prepared areas are characterised by agricultural ecosystems. This reading approach based on land cover analyses can thus assist in developing policies to enhance different territorial capacities, ultimately leading to better and more sustainable decision-making

Sea urchin chronicles. The effect of oxygen super-saturation and marine polluted sediments from Bagnoli-Coroglio Bay on different life stages of the sea urchin Paracentrotus lividus

In marinas and harbours, the accumulation of pollutants in sediments, combined with poor exchange of water with the open sea, poses a major environmental threat. The presence of photosynthetic organisms and the related oxygen production, however, may alleviate the negative effects of environmental contamination on heterotrophic organisms, enhancing their physiological defences. Furthermore, possible transgenerational buffer effects may increase the ability of natural populations to face environmental stress. Here we tested the occurrence of transgenerational effects on larvae of the sea urchin Paracentrotus lividus, whose parents were exposed, during the gametogenesis, to contaminated sediments subject to two temporal patterns of water re-suspension events and normal- (90%) vs. super-saturated (200%) levels of O2. The study site was Bagnoli-Coroglio (Gulf of Naples, southern Tyrrhenian Sea), a historically polluted brownfield and Site of National Interest for which environmental restoration options are currently under exploration. Larvae from different adult populations were significantly, although not linearly, affected by the interaction of all factors to which parents were exposed, at both 24h and 48h post fertilization. Specifically, the exposure of larvae to elutriates from contaminated sediments determined a developmental delay, a reduction in size and an increased percentage of abnormalities in all larval populations independently of their parental exposure. On the contrary, larvae from parents exposed to contaminated sediments, when reared in clean filtered sea water, succeeded in developing until the echinopluteus stage after 48h, with size and abundance comparable to those of larvae from control parents. Pre-exposure of parents to contaminated sediments did not successfully buffer the negative effects of elutriates on their offspring, and no positive effects of ‘super-saturated’ levels of O2 in response to contaminants were observed, suggesting that the Bagnoli-Coroglio area is currently not suitable for the re-stocking or re-introduction of this species

A comprehensive luminal breast cancer patient-derived xenografts (PDX) library to capture tumor heterogeneity and explore the mechanisms of resistance to CDK4/6 inhibitors

Breast cancer (BC) is marked by significant genetic, morphological and clinical heterogeneity. To capture this heterogeneity and unravel the molecular mechanisms driving tumor progression and drug resistance, we established a comprehensive patient-derived xenograft (PDX) biobank, focusing particularly on luminal (estrogen receptor, ER+) and young premenopausal patients, for whom PDX models are currently scarce. Across all BC subtypes, our efforts resulted in an overall success rate of 17% (26 established PDX lines out of 151 total attempts), specifically 15% in luminal, 12% in human epidermal growth factor receptor 2 positive (HER2+) and 35% in triple negative BC. These PDX mirrored morphologic and genetic features of BC from which they originated, serving as a reliable tool to investigate drug resistance and test therapeutic strategies. We focused on understanding resistance to CDK4/6 inhibitors (CDK4/6i), which are crucial in the treatment of patients with advanced luminal BC. Treating a sensitive luminal BC PDX with the CDK4/6i palbociclib revealed that, despite initial tumor shrinkage, some tumors might eventually regrow under drug treatment. RNA sequencing, followed by gene set enrichment analyses, unveiled that these PDXs have become refractory to CDK4/6i, both at biological and molecular levels, displaying significant enrichment in proliferation pathways, such as MTORC1, E2F and MYC. Using organoids derived from these PDX (PDxO), we observed that acquisition of CDK4/6i resistance conferred cross-resistance to endocrine therapy and that targeting MTORC1 was a successful strategy to overcome CDK4/6i resistance. Considered together, these results indicate that our PDX models may serve as robust tools to elucidate the molecular basis of BC disease progression and, by providing the possibility to simultaneously test different therapies on the same tumor, to surmount treatment resistance. While this approach is of course not feasible in the clinic, its exploitation in PDX may expedite the identification and development of more successful therapies for patients with advanced luminal BC. © 2024 The Author(s).

Innovative multidisciplinary tool for screening bowel and bladder symptoms in multiple sclerosis

Introduction: Bowel and bladder symptoms are frequent in people with Multiple Sclerosis (PwMS) and early diagnosis and treatment become crucial to improve their quality of life (QoL). The study aims to design a multidisciplinary questionnaire for screening bladder and bowel symptoms in PwMS. Materials and methods: The Bowel and Bladder Symptoms Screening in Multiple Sclerosis (BBSS-MS) questionnaire for screening bowel and bladder symptoms was designed in Italian following a three-steps process. In the first step, a dedicated board of experts identified a pool of items, which will be analysed for content, clarity, and consistency during the second step. During the third step, the relevance of each item was evaluated through a two-round process following the Delphi method. For each round of the Delphi method, medians, the 25th and 75th percentiles, and the IQR of the score for each statement were calculated. Stata 16.1 software was used to conduct all analyses. Results: The Board identified 22 items to include in the BBSS-MS, based on existing questionnaire and clinical expertise. After discussing about the comprehensibility and clarity of items, the first version of the BBSS-MS composed of 22 items was proposed. Following, a Panel of 44 experts scored the relevance of each question and all the questions reached the score to be included in the questionnaire. The final 21-item version of the BBSS-MS was proposed. Discussion and conclusion: To our knowledge, the BBSS-MS represents the first self-reported hybrid questionnaire for screening bladder and bowel symptoms in an Italian MS population

Verso una lettura integrata del territorio: la valutazione dei servizi ecosistemici come strumento di supporto alle decisioni

La complessità che caratterizza i sistemi urbani implica la necessità di osservare in maniera trasversale e integrata le molteplici ed eterogenee dinamiche territoriali per far emergere le criticità da contrastare e le opportunità da cogliere. Tale lettura è resa possibile dall’impiego delle nuove tecnologie dell’informazione spaziale, che assumono un ruolo di supporto ai processi di pianificazione. Tuttavia, appare indispensabile interpretare contestualmente i dati per evitare di tralasciare le variabili complesse che gli strumenti informatici non sono in grado di percepire e, di conseguenza, identificare. Quanto occorre è ridefinire le finalità della disciplina urbanistica in un’ottica di resilienza, salvaguardia ambientale e benessere sociale, ricostruendo il sistema valoriale a partire dalla consapevolezza dell’interdipendenza tra uomo e natura. Il prezioso valore rappresentato dal capitale naturale, sommato alle pressioni derivanti dal cambiamento climatico in corso, comporta l’esigenza di considerare temi quali le infrastrutture verdi e i servizi ecosistemici (SE) ad esse connessi all’interno degli ordinari strumenti di governo del territorio. Il presente contributo indaga la mappatura dei SE a partire dalla costruzione di matrici valutative, al fine di individuare un modello di lettura unico e integrato che sia funzionale anche alla definizione di apposite strategie di adattamento ai cambiamenti climatici

Sperimentazione e validazione di nuove tecnologie per il miglioramento della shelflife dei prodotti ittici attraverso l’uso di un film edibile a base pectinica

Quando si parla di shelf life di un prodotto alimentare si fa riferimento al periodo di tempo durante il quale un prodotto mantiene le sue caratteristiche qualitative nelle normali condizioni di conservazione/utilizzo e di conseguenza può essere consumato in totale sicurezza. Gli alimenti, infatti, sono prodotti facilmente deperibili che subiscono modifiche a carico della loro composizione a causa dell’innesco di una serie di reazioni sia di tipo microbiologico che chimico-fisico, con i conseguenti rischi per la sicurezza igienico sanitaria del prodotto. Nei prodotti ittici la degradazione biologica risulta essere una delle prime cause di deterioramento dell’alimento ciò perché essi stessi sono caratterizzati dalla presenza di microrganismi provenienti principalmente dalle materie prime impiegate e dal processo di produzione/preparazione utilizzato. Durante la conservazione e lo stoccaggio del prodotto ittico, in particolare sono tre i meccanismi che determinano il deterioramento e quindi la riduzione della shelf life, ovvero: l’autolisi enzimatica (post mortem e che modifica la consistenza del tessuto muscolare favorendo inoltre la crescita microbica ed il rilascio di ammine biogene); l’ossidazione (che riduce le qualità organolettiche del prodotto alterando gli acidi grassi poliinsaturi); la crescita microbica (con produzione di metaboliti come ammine biogene, acidi organici, solfiti, alcool, aldeidi e chetoni che causano i cattivi odori) (Jiang et al. 1990, Koohmaraie M., 1996, Koutsoumanis& Nychas, 1999, Aoki et al., 1997; Bremner, 1992). Risulta quindi strategico, il poter determinare la conservabilità di un alimento verificando dal punto di vista quantitativo, come tutti i fattori che contribuiscono all’alterazione della qualità del prodotto e all’incremento del processo degradativo (popolazione microbica, attività enzimatiche, variazioni chimiche) varino nel tempo

Tra fragilità e opportunità: l’impiego dei servizi ecosistemici per la riduzione del rischio climatico nella pianificazione regionale

I servizi ecosistemici di regolazione (SER) – come il sequestro e lo stoccaggio del carbonio, la regolazione dell’acqua o il controllo dell’erosione – contribuiscono in modo determinante a ridurre il rischio climatico. Tuttavia, l’inclusione dei SER negli strumenti di pianificazione è ancora limitata e presenta molteplici lacune informative. Emerge la necessità di dotarsi di quadri conoscitivi transdisciplinari, integrati e integrabili che sintetizzino la complessità ed eterogeneità territoriale. In tal senso, l’impiego di metodi innovativi a livello locale facilita la comprensione delle fragilità e delle opportunità in una lettura adattiva del territorio, fornendo supporto ai processi decisionali e maggiore flessibilità agli strumenti di pianificazione. Il presente contributo propone e testa una metodologia per introdurre la conoscenza sui SER nella pianificazione regionale ordinaria in un’ottica di riduzione delle vulnerabilità e gestione sostenibile del territorio e delle sue risorse. Essa si basa sul collegamento tra i dati della copertura del suolo e una ricognizione degli impatti del cambiamento climatico previsti su sistemi naturali e settori socioeconomici. In particolare, le fasi di cui è costituita sono due: i) l’identificazione di un set di SE prioritari per la riduzione del rischio climatico (domanda); ii) la mappatura dell’attuale offerta potenziale dei SE selezionati. La metodologia è applicata al caso studio illustrativo della Regione Autonoma Friuli Venezia Giulia (FVG) nell’ambito della revisione del Piano di Governo del Territorio (PGT)
