The Challenge of Planning Conservation Strategies in Threatened Seascapes: Understanding the Role of Fine Scale Assessments of Community Response to Cumulative Human Pressures

Assessing the distribution and intensity of human threats to biodiversity is a prerequisite for effective spatial planning, harmonizing conservation purposes with sustainable development. In the Mediterranean Sea, the management of Marine Protected Areas (MPAs) is rarely based on explicit consideration of the distribution of multiple stressors, with direct assessment of their effects on ecosystems. This gap limits the effectiveness of protection and is conducive to conflicts among stakeholders. Here, a fine scale assessment of the potential effects of different combinations of stressors (both land- and marine-based) on vulnerable rocky habitats (i.e. lower midlittoral and shallow infralittoral) along 40 km of coast in the western Mediterranean (Ionian Sea) has been carried out. The study area is a paradigmatic example of socio-ecological interactions, where several human uses and conservation measures collide. Significant differences in the structure of assemblages according to different combinations of threats were observed, indicating distinct responses of marine habitats to different sets of human pressures. A more complex three-dimensional structure, higher taxon richness and \u3b2-diversity characterized assemblages subject to low versus high levels of human pressure, consistently across habitats. In addition, the main drivers of change were: closeness to the harbour, water quality, and the relative extension of beaches. Our findings suggest that, although efforts to assess cumulative impacts at large scale may help in individuating priority areas for conservation purposes, the fact that such evaluations are often based on expert opinions and not on actual studies limits their ability to represent real environmental conditions at local scale. Systematic evaluations of local scale effects of anthropogenic drivers of change on biological communities should complement broad scale management strategies to achieve effective sustainability of human exploitation of marine resources

Biomechanical and proteomic analysis of INF- β-treated astrocytes

Astrocytes have a key role in the pathogenesis of several diseases including multiple sclerosis and were proposed as the designed target for immunotherapy. In this study we used atomic force microscopy (AFM) and proteomics methods to analyse and correlate the modifications induced in the viscoleastic properties of astrocytes to the changes induced in protein expression after interferon- beta (IFN-beta) treatment. Our results indicated that IFN-beta treatment resulted in a significant decrease in the Young's modulus, a measure of cell elasticity, in comparison with control cells. The molecular mechanisms that trigger these changes were investigated by 2DE (two-dimensional electrophoresis) and confocal analyses and confirmed by western blotting. Altered proteins were found to be involved in cytoskeleton organization and other important physiological processes

Ovarian Cancer Biomarkers: A Focus on Genomic and Proteomic Findings

Among the gynaecological malignancies, ovarian cancer is one of the neoplastic forms with the poorest prognosis and with the bad overall and disease-free survival rates than other gynaecological cancers; several studies, analyzing clinical data and pathological features on ovarian cancers, have focused on the identification of both diagnostic and prognostic markers for applications in clinical practice. High-throughput technologies have accelerated the process of biomarker discovery, but their validity should be still demonstrated by extensive researches on sensibility and sensitivity of ovarian cancer novel biomarkers, determining whether gene profiling and proteomics could help differentiate between patients with metastatic ovarian cancer and primary ovarian carcinomas, and their potential impact on management

Mediterranean Cropping Systems: The Importance of Their Economic and Environmental Sustainability

The COVID-19 pandemic has drastically changed the lives of people, as well as the production and economic systems throughout the world. The flow of raw materials and products, the supply of labor and manpower, and the purchasing power have all been changed to the detriment of individual health and well-being. Such a situation requires placing even more emphasis on the search for virtuous agricultural systems compatible with the goals of economic and environmental development so clearly defined at the world level in the last decades. The present study aimed to assess the environmental and economic performance of some typical Mediterranean crops grown under different agronomical management regimes, such as strawberry, hazelnut, apricot tree, kiwifruit, peach, olive tree, and grapevine, to emphasize the importance of the mentioned issues even in the current pandemic situation. Life cycle assessment (LCA) was used to investigate the environmental profile of the studied crops, while lifecycle costing (LCC) was performed to assess and compare the economic aspects. From the environmental perspective, the hobby-organic olive systems were the most eco-friendly cropping systems, emitting 0.031 to 0.105 kg CO2eq per kg olives, while the organic hazelnut system had the greatest impact (1.001 kg of CO2eq per kg). Apricot, kiwifruit, and peach systems used N and P inputs most effectively, while strawberry systems efficiently used fossil fuels. Olive HO-2, kiwifruit, and peach cropping systems had the lowest budgets, with the costs amounted to 0.12 € kg-1 per fruit for Olive HO-2 and 0.28 € kg-1 per fruit for both kiwifruit and peach. On the contrary, organic strawberry cultivation was the most expensive (4.77 € kg-1). The variability in results due to the large differences between contexts, such as landscape, technical knowledge, and crop management, characterized the studied agricultural systems. To easily identify sustainability classes and to diminish the impact of farming practices, a considerable effort should be expended to combine LCA with LCC, C sequestration estimates, and some other useful indicators for the environmental quality evaluation

Early Rehabilitation Reduces Time to Decannulation in Patients With Severe Acquired Brain Injury: A Retrospective Study

Purpose: Early decannulation is considered a main rehabilitative goal in tracheostomized patients. Our aim is to evaluate whether a very early rehabilitation protocol helps to reduce the tracheostomy duration in patients affected by an Acquired Brain Injury (ABI).Methods: Data about consecutive tracheostomized patients admitted in our Neuro-Rehabilitation Unit (NRU) were retrospectively collected. We defined two groups: Early Rehabilitation Group patients came from our ICU, where they started the rehabilitative treatment; Delayed Rehabilitation Group patients arrived from external ICUs and started rehabilitation in our NRU. Primary outcome was the time from tracheostomy to decannulation. Secondary outcomes were: ICU length of stay, time from NRU admission to decannulation, Glasgow Coma Scale, Coma Recovery Scale revised and Levels of Cognitive Functioning scores at NRU discharge and the re-cannulation rate.Results: We enrolled 66 patients, 40 in the Early Rehabilitation Group and 26 in the Delayed Rehabilitation Group. 70% of patients for each group could be decannulated (p = 0.73) and were analyzed. Only one patient was re-cannulated. Early Rehabilitation Group showed a shorter tracheostomy duration (61.0 vs. 94.5 days, p = 0.013), a higher probability of occurrence of decannulation (p = 0.008) and a lower ICU length of stay (30.0 vs. 52.0 days, p = 0.001). The time to decannulation in NRU was similar between groups (30.0 vs. 45.50 days, p = 0.14). All the scale scores had a significant improvement in both groups (p < 0.0001 all).Conclusions: The present study shows that an early neuro-rehabilitation protocol helps to reduce the time to decannulation in tracheostomized patients affected by ABI

Genetic analyses identify brain structures related to cognitive impairment associated with elevated blood pressure

Background and aims Observational studies have linked elevated blood pressure (BP) to impaired cognitive function. However, the functional and structural changes in the brain that mediate the relationship between BP elevation and cognitive impairment remain unknown. Using observational and genetic data from large consortia, this study aimed to identify brain structures potentially associated with BP values and cognitive function. Methods and results Data on BP were integrated with 3935 brain magnetic resonance imaging-derived phenotypes (IDPs) and cognitive function defined by fluid intelligence score. Observational analyses were performed in the UK Biobank and a prospective validation cohort. Mendelian randomisation (MR) analyses used genetic data derived from the UK Biobank, International Consortium for Blood Pressure, and COGENT consortium. Mendelian randomisation analysis identified a potentially adverse causal effect of higher systolic BP on cognitive function [−0.044 standard deviation (SD); 95% confidence interval (CI) −0.066, −0.021] with the MR estimate strengthening (−0.087 SD; 95% CI −0.132, −0.042), when further adjusted for diastolic BP. Mendelian randomisation analysis found 242, 168, and 68 IDPs showing significant (false discovery rate P < 0.05) association with systolic BP, diastolic BP, and pulse pressure, respectively. Most of these IDPs were inversely associated with cognitive function in observational analysis in the UK Biobank and showed concordant effects in the validation cohort. Mendelian randomisation analysis identified relationships between cognitive function and the nine of the systolic BP-associated IDPs, including the anterior thalamic radiation, anterior corona radiata, or external capsule. Conclusion Complementary MR and observational analyses identify brain structures associated with BP, which may be responsible for the adverse effects of hypertension on cognitive performance

3-Aroyl-1,4-diarylpyrroles inhibit chronic myeloid leukemia cell growth through an interaction with tubulin

We designed 3-aroyl-1,4-diarylpyrrole (ARDAP) derivatives as potential anticancer agents having different substituents at the 1- or 4-phenyl ring. ARDAP compounds exhibited potent inhibition of tubulin polymerization, binding of colchicine to tubulin, and cancer cell growth. ARDAP derivative 10 inhibited the proliferation of BCR/ABL-expressing KU812 and LAMA84 cells from chronic myeloid leukemia (CML) patients in blast crisis and of hematopoietic cells ectopically expressing the imatinib mesylate (IM)-sensitive KBM5-WT or its IM-resistant KBM5-T315I mutation. Compound 10 minimally affected the proliferation of normal blood cells, indicating that it may be a promising agent to overcome broad tyrosine kinase inhibitor resistance in relapsed/refractory CML patients. Compound 10 significantly decreased CML proliferation by inducing G2/M phase arrest and apoptosis via a mitochondria-dependent pathway. ARDAP 10 augmented the cytotoxic effects of IM in human CML cells. Compound 10 represents a robust lead compound to develop tubulin inhibitors with potential as novel treatments for CML

Sustainable Bulk-Packaging System for Sugar Shipping: Case Study of the Enterprise Leader in Europe

From 2002 to today, world sugar production has steadily increased due to higher food consumption and biofuel production. Furthermore, in the European Union, the CAP 2014–2020 new reform abolished the system of production and sugar exportation quotas by 1 October 2017. Therefore, since that date, the international sugar exchange has significantly increased in light of these new structural and political–economic conditions. Thus, companies offering a new bulk-packaging technology for international shipping could increase their market success. At the same time, the possibility for the same buyers (from sugar producers to logistic agencies) to use a safer and more sustainable packaging system has become important for economic and environmental cost reduction. The present study aims at presenting the experience of a small Italian enterprise that became a European leader in this sector due to its patents concerning a new, more efficient and sustainable product for bulk sugar transport in containers. This technological innovation represents not only a noteworthy sustainable business strategy for becoming more competitive in the market, but also a system for ensuring more effective sugar transport, mainly for the reduction in management costs (up to 65%) for buyers

Closed rhinoplasty: effects and changes on voice - a preliminary report

Aim: Effects of rhinoplasty were already studied from many points of view: otherwise poor is scientific production focused on changes of voice after rhinoplasty. This preliminary study analyzed objectively and subjectively these potential effects on 19 patients who underwent exclusively closed rhinoplasty.Methods: This preliminary evaluation was conducted from September 2012 to May 2013 and 19 patients have undergone primary rhinoplasty with exclusively closed approach (7 males, 12 females). All patients were evaluated before and 6 months after surgery. Each of them answered to a questionnaire (Voice Handicap Index Score) and the voice was recorded for spectrographic analysis: this system allowed to perform the measurement of the intensity and frequency of vowels (“A” and “E”) and nasal consonants (“N” and “M”) before and after surgery. Data were analysed with the Mann-Whitney test.Results: Sixteen patients showed statistically significant differences after surgery. It was detected in 69% of cases an increased frequency of emission of the consonant sounds (P = 0.046), while in 74% of cases the same phenomenon was noticed for vowel sounds (P = 0.048).Conclusion: Many patients who undergo rhinoplasty think that the intervention only leads to anatomical changes and improvement of respiratory function. The surgeon should instead accurately inform patients about the potential effects on the voice. This preliminary study reveals the significant effects of closed rhinoplasty on the human voice
