D4.2: Regional Mapping Report on Green Transition

This report aims to give findings from comparative research on Green Transition processes through developed policies, engaged actors, and implemented practices and initiatives, identified on the territories of five Western Balkan countries (AL, BA, ME, MK, RS). It builds upon 5 datasets, which serve as indications for the prospective results of the green transition as well as the immediate and long-term effects that society can anticipate. The mapping report's specific goal is to highlight the elements of the Western Balkans’ Green Agenda that are more embedded in the current national policy frameworks and those that require additional support in reaching the 2030 GT targets

The Missing Link - Likely Pathogenetic Role of GM3 and Other Gangliosides in the Development of Diabetic Nephropathy

Despite scientific advances, diabetic nephropathy remains both a therapeutical challenge, and one of the major diabetic complications. Chemical structure of gangliosides, the most complex of glycosphingolipids, is characterised by one or more sialic acids and carbohydrate groups linked to a ceramide structure. Their potential pathogenetic role in a number of disorders linked to diabetes mellitus has recently been conjectured, due to evidence of their negative modulation of the insulin-mediated signaling and general effects on key cell functions like proliferation, differentiation, apoptosis, cellular signaling and adhesion. Elevated levels of advanced glycation products (AGE) usually found in diabetic conditions seem to be responsible for increased concentration of a-series gangliosides in tissues, most notably GM3. GM3 was shown to compromise the renal pericyte and mesangial cell regeneration via the inactivation of VEGF receptor and the receptor-associated Akt signaling pathway. Likewise, the lipid raft theory opened a new research area for GM3 influence, since in the glycosynapse model glycosphingolipids have a key cell-to-cell communication unit with modulating capabilities on signaling receptors. The goal of this review is to provide insight into currently available theories on proposed mechanisms that mark the GM3 as a pathophysiological mediator in the development of diabetic nephropathy

Interleukin-1β/Interleukin (IL)-1-Receptor-Antagonist (IL1-RA) Axis in Invasive Bladder Cancer—An Exploratory Analysis of Clinical and Tumor Biological Significance

Previous data indicate a role of IL-1 and IL-1RA imbalance in bladder carcinoma (BC); the inhibition of IL-1 signaling might be considered a treatment option. Objective: To assess expression patterns and the prognostic role of IL-1β and IL-1RA in invasive BC and to evaluate their interaction with AKT signaling and proliferation. The study included two independent cohorts of n = 92 and n = 102 patients who underwent a radical cystectomy for BC. Specimen from BC and benign urothelium (n = 22 and n = 39) were processed to a tissue microarray and immunohistochemically stained for IL-1β, IL-1RA, AKT, and Ki-67. Expression scores were correlated to clinical variables and Ki-67 and AKT expression. An association with outcome was assessed using Wilcoxon Kruskal–Wallis tests, Chi-square tests or linear regression, dependent on the variable’s category. Kaplan–Meier and Cox proportional hazard analyses were used to estimate recurrence-free (RFS), cancer-specific (CSS) and overall survival (OS). Both IL-1β and IL-1RA were significantly overexpressed in invasive BC compared to benign urothelium in both cohorts (p p p p 15%) correlated with higher levels of IL-1β (p = 0.01). The overexpression of IL-1β and IL-1RA is frequently found in BC, with a prognostic significance observed for the IL-1β protein expression. The observed link between the IL-1β/IL-1RA axis and AKT signaling may indicate possible autophagy activation processes besides the known tumor-promoting effects of AKT

Automatic deep learning-based pleural effusion segmentation in lung ultrasound images

BackgroundPoint-of-care lung ultrasound (LUS) allows real-time patient scanning to help diagnose pleural effusion (PE) and plan further investigation and treatment. LUS typically requires training and experience from the clinician to accurately interpret the images. To address this limitation, we previously demonstrated a deep-learning model capable of detecting the presence of PE on LUS at an accuracy greater than 90%, when compared to an experienced LUS operator.MethodsThis follow-up study aimed to develop a deep-learning model to provide segmentations for PE in LUS. Three thousand and forty-one LUS images from twenty-four patients diagnosed with PE were selected for this study. Two LUS experts provided the ground truth for training by reviewing and segmenting the images. The algorithm was then trained using ten-fold cross-validation. Once training was completed, the algorithm segmented a separate subset of patients.ResultsComparing the segmentations, we demonstrated an average Dice Similarity Coefficient (DSC) of 0.70 between the algorithm and experts. In contrast, an average DSC of 0.61 was observed between the experts.ConclusionIn summary, we showed that the trained algorithm achieved a comparable average DSC at PE segmentation. This represents a promising step toward developing a computational tool for accurately augmenting PE diagnosis and treatment

Longitudinal profile of the genotoxic potential of the River Danube on erythrocytes of wild common bleak (Alburnus alburnus) assessed using the comet and micronucleus assay

The Joint Danube Survey 3 (JDS3; the biggest river expedition in 2013) had offered the unique opportunity for a large-scale monitoring approach for biomarker response in feral fish collected along a Danube stretch from Kehlheim (DE) to Sulina (RO). The advantage of genotoxicity as a marker for pollution exposure in fish is the early detection of possible long-term effects such as cancer. Therefore, genotoxicity was in the focus of the biomarker investigations in fish during the expedition. Blood samples of common bleak (Alburnus alburnus) for the investigation of the micronucleus frequency and comet tail intensity of fragmented DNA material in erythrocytes were collected at 18 and 12 sampling sites, respectively. For 9 sampling sites same samples were used to compare the in-situ data for the comparable genotoxic endpoint in the micronucleus (MN) and comet assay (CM). The data of both.in-situ assays showed a significant correlation, indicating the strength and comparability of the data sets. Significant variation in DNA damage in-fish along the longitudinal profile of the Danube was demonstrated for both assays compared to reference sites. The results suggest that DNA damage in erythrocytes of fish was mainly affected by wastewater of highly populated regions. No linkage between the results and the general health/dietary status of the fish were revealed, whereas correlation with some genotoxicity drivers in the water phase, suspended particulate matter and sediments could be demonstrated
