AGROALIMENTARE E SVILUPPO ECONOMICO SOSTENIBILE: ENERGIA, EFFICIENZA ENERGETICA, AMBIENTE E CIBO

Nell’ultimo decennio, il sistema agroalimentare nazionale nella sua accezione più ampia di agricoltura e industria alimentare, ha assunto una configurazione fortemente sistemica, aperta al contributo di diverse discipline e tecnologie. Tale evoluzione ha consentito al sistema agricolo di raggiungere posizioni ragguardevoli se consideriamo che nel complesso l’agroalimentare rappresenta per l’economia italiana un valore di 250 miliardi €, pari a circa 16% del PIL. Il mondo agricolo, nel suo complesso, costituisce ormai uno snodo fondamentale per attività che riguardano: l’energia, l’ambiente, il cibo, il territorio, il benessere dei cittadini, il sistema economico aree urbane-aree rurali. Il lavoro è focalizzato sul ruolo strategico dell’agroalimentare per gli obiettivi del Pacchetto Europeo 20-20-20 nonché per lo sviluppo economico sostenibile del sistema Paese.Agriculture and economic sustainable development: energy, energy efficiency, environment and food This article briefly examines the evolution of the agricultural sector in Italy and outlines the concept of the agro-food system that includes the agriculture and the food industry activities. The Italian agro-food system has reached a global annual value of 250 billions €, which corresponds to about 16% of the added gross value. The agricultural system is also analyzed in respect to the objectives of the European Package 20-20-20. This article outlines the impact of the agro-food system in terms of energy, energy efficiency, use of renewable resources related to the food production. The impact of the large retail groups and the key role of the agro-food system are also analyzed in respect to the development of a sustainable economy

Sustainable greenhouse horticulture in Europe

The European greenhouse horticulture represents one of the most intensive energy sector in agriculture and strongly contributes to increase the energy and environmental vulnerability within regions having a large greenhouse farming systems. Specifically, the European greenhouse farming sector is facing a trend that responds to the changing consumer’s demands in a society that, globally, is increasingly affluent but more aware about some negative consequences, such as high energy-demand processes, and CO2 emissions. About 200,000 hectares of greenhouses in Spain, Italy, The Netherlands and Greece is the estimated covered surface, with not less than 3.4 MTOE of energy consumption and 9.2 MtCO2eq, and an yearly economy value of 7 billions of Euros. The installed energy power load of greenhouses in Europe depends on local climate conditions, and varies from 50-150 W/m2 (Southern regions of Europe) to 200-280 W/m2 (Northern and Central regions), while complete conditioning could even reach an energy load of 400 W/m2 (heating, lighting, cooling). Nowadays, the proportion of renewable use in the total energy consumption of greenhouse farming in Europe is very low, and there are no clear priorities set in this area, yet. Comprehensive and complete studies that evaluate the opportunities of renewable options in greenhouse sector are still not completeted. This, strongly hinders the process of setting concrete goals and legislative targets to support a wider introduction of sustainable energy technology, and appropriate legislation in greenhouse regions of Europe. This paper deals with the proposal of supporting the organization of a sustainable greenhouse agriculture, based on renewable energy sources, i.e. geothermal energy at low temperature, photovoltaic solar energy and solid biomass, in tune with the specific local assets, the local geo-climatic conditions and the protection of landscapes rather than with a careless perspective for local environment and potential societal costs

Proteomic changes and molecular effects associated with Cr(III) and Cr(VI) treatments on germinating kiwifruit pollen

The present study is aimed at identifying molecular changes elicited by Cr(III) and Cr(VI) on germinating kiwifruit pollen. To address this question, comparative proteomic and DNA laddering analyses were performed. While no genotoxic effect was detected, a number of proteins whose accumulation levels were altered by treatments were identified. In particular, the upregulation of some proteins involved in the scavenging response, cell redox homeostasis and lipid synthesis could be interpreted as an oxidative stress response induced by Cr treatment. The strong reduction of two proteins involved in mitochondrial oxidative phosphorylation and a decline in ATP levels were also observed. The decrease of pollen energy availability could be one of the causes of the severe inhibition of the pollen germination observed upon exposure to both Cr(III) and Cr(VI). Finally, proteomic and biochemical data indicate proteasome impairment: the consequential accumulation of misfolded/damaged proteins could be an important molecular mechanism of Cr(III) toxicity in pollen

Breast Cancer Following Hodgkin's Disease

The advent of effective chemo-radiotherapy has made Hodgkin Disease (HD) a highly curable malignancy, but the great improvement in survival rates allowed the observation in long-term survivors of several treatment complications. Secondary malignancies are the most serious complications and breast cancer (BC) represents the most common solid tumor among female survivors. The aim of our analysis is to describe the clinico-pathological characteristics and management of BC occurred after HD treatment. Between 1960 and 2003, 2,039 patients were treated for HD at the Department of Radiotherapy-Oncology of the Florence University. In this study we considered 1,538 patients on whom a minimum follow up of 6 months had been obtained. Of these, 725 were women. The most represented histological subtype was nodular sclerosis (50.6%). Supradiaphragmatic alone or with subdiaphragmatic complementary extended field radiotherapy was delivered to 83.1% of patients while supradiaphragmatic involved field radiotherapy was delivered to 10.7% of patients. Concerning the characteristics and incidence of BC, we focused our analysis exclusively on the female group. We found that BC occurred in 39, with an overall incidence of 5.4%. The mean interval after Hodgkin treatment was 19.5 years (SD +/- 9.0). The median age of BC diagnosis was 50.8 years (SD +/- 13.3) while the median age of Hodgkin diagnosis was 31.2 years (SD +/- 14.5). Thirty-seven women received mediastinal irradiation. We observed a decreasing trend of the secondary BC incidence with increasing age of Hodgkin treatment with the maximum incidence registered in women treated at age 20 or younger. In Our Institute we perform a whole life follow up and recommend that annual mammography begins 10 years after HD treatment or, in any case, not later than age 40

Extraskeletal osteosarcoma: A European Musculoskeletal Oncology Society study on 266 patients

PURPOSE: Prognosis of extraskeletal osteosarcoma (ESOS) is reported to be poorer than that of skeletal osteosarcoma. This multicenter retrospective study aimed to evaluate factors influencing ESOS prognosis. PATIENTS AND METHODS: Members of the European Musculoskeletal Oncology Society (EMSOS) submitted institutional data on patients with ESOS. RESULTS: Data from 274 patients treated from 1981 to 2014 were collected from 16 EMSOS centres; 266 patients were eligible. Fifty (18.7%) had metastases at diagnosis. Of 216 patients with localised disease, 211 (98%) underwent surgery (R0 = 70.6%, R1 = 27%). Five-year overall survival (OS) for all 266 patients was 47% (95% CI 40-54%). Five-year OS for metastatic patients was 27% (95% CI 13-41%). In the analysis restricted to the 211 localised patients who achieved complete remission after surgery 5-year OS was 51.4% (95% CI 44-59%) and 5-year disease-free survival (DFS) was 43% (95% CI 35-51%). One hundred twenty-one patients (57.3%) received adjuvant or neoadjuvant chemotherapy and 80 patients (37.9%) received radiotherapy. A favourable trend was seen for osteosarcoma-type chemotherapy versus soft tissue sarcoma-type (doxorubicin ± ifosfamide) regimens. For the 211 patients in complete remission after surgery, patient age, tumour size, margins and chemotherapy were positive prognostic factors for DFS and OS by univariate analysis. At multivariate analysis, patient age (≤40 years versus >40 years) (P = 0.05), tumour size (P = 0.0001) and receipt of chemotherapy (P = 0.006) were statistically significant prognostic factors for survival. CONCLUSION: Patient age and tumour size are factors influencing ESOS prognosis. Higher survival was observed in patients who received perioperative chemotherapy with a trend in favour of multiagent osteosarcoma-type regimen which included doxorubicin, ifosfamide and cisplatin.info:eu-repo/semantics/publishedVersio

Can a lifestyle intervention be offered through NHS breast cancer screening?:Challenges and opportunities identified in a qualitative study of women attending screening

Background: Around one third of breast cancers in post-menopausal women could be prevented by decreasing body fatness and alcohol intake and increasing physical activity. This study aimed to explore views and attitudes on lifestyle intervention approaches in order to inform the proposed content of a lifestyle intervention programme amongst women attending breast cancer screening. Methods: Women attending breast cancer screening clinics in Dundee and Glasgow, were invited to participate in focus group discussions (FGD) by clinic staff. The groups were convened out with the clinic setting and moderated by an experienced researcher who attained brief details on socio-demographic background and audio-recorded the discussions. Data analysis was guided by the framework approach. The main topics of enquiry were: Understanding of risk of breast cancer and its prevention, views on engaging with a lifestyle intervention programme offered through breast cancer screening and programme design and content. Results: Thirty one women attended 5 focus groups. Participant ages ranged from 51 to 78 years and 38 % lived in the two most deprived quintiles of residential areas. Women were generally positive about being offered a programme at breast cancer screening but sceptical about lifestyle associated risk, citing genetics, bad luck and knowing women with breast cancer who led healthy lifestyles as reasons to query the importance of lifestyle. Engagement via clinic staff and delivery of the programme by lifestyle coaches out with the screening setting was viewed favourably. The importance of body weight, physical activity and alcohol consumption with disease was widely known although most were surprised at the association with breast cancer. They were particularly surprised about the role of alcohol and resistant to thinking about themselves having a problem. They expressed frustration that lifestyle guidance was often conflicting and divergent over time. The concept of focussing on small lifestyle changes, which were personalised, supported socially and appropriate to age and ability were welcomed. Conclusions: Offering access to a lifestyle programme through breast screening appears acceptable. Explaining the relevance of the target behaviours for breast cancer health, endorsing and utilising consistent messages and identifying personalised, mutually agreed, behaviour change goals provides a framework for programme development
