This study investigates ground deformations in the southeastern Po Plain (northern Italy), focusing on the Bologna area—a densely populated region affected by natural and anthropogenic subsidence. Ground deformations in the area result from geological processes (e.g., sediment compaction and tectonic activity) and human activities (e.g., ground water production and underground gas storage—UGS). We apply a multidisciplinary approach integrating subsurface geology, ground water production, advanced differential interferometry synthetic aperture radar—DInSAR, gas storage data, and land use information to characterize and analyze the spatial and temporal variations in vertical ground deformations. Seasonal and trend decomposition using loess (STL) and cluster analysis techniques are applied to historical DInSAR vertical time series, targeting three representatives areas close to the city of Bologna. The main contribution of the study is the attempt to correlate the lateral extension of ground water bodies with seasonal ground deformations and water production data; the results are validated via knowledge of the geological characteristics of the uppermost part of the Po Plain area. Distinct seasonal patterns are identified and correlated with ground water production withdrawal and UGS operations. The results highlight the influence of superficial aquifer characteristics—particularly the geometry, lateral extent, and hydraulic properties of sedimentary bodies—on the ground movements behavior. This case study outlines an effective multidisciplinary approach for subsidence characterization providing critical insights for risk assessment and mitigation strategies, relevant for the future development of CO₂ and hydrogen storage in depleted reservoirs and saline aquifers.

Dermatophytes are keratinophilic fungi that cause a wide range of superficial infections in humans and animals. The Trichophyton mentagrophytes species complex is one of the most clinically important groups due to its broad host range, widespread distribution, and increasing involvement in antifungal-resistant infections. Here, we described the epidemiology of T. mentagrophytes over a period of 4 years detected in the northeastern part of Italy and provided the genomic characterization of clinical isolates. ITS sequence analysis revealed that among the 13 strains studied, 11 belonged to the T. mentagrophytes complex. In detail, nine were classified as genotype I/II and two as genotype VII. Analysis of the SQLE gene revealed that nine strains harbored a wild-type gene, while two carried a Lys276Asn mutation. Genomic analysis was performed on three clinical T. mentagrophytes strains that belonged to genotype I/II, revealing the presence of different virulence factors including MEP-1, MEP-2, MEP-3, and MEP-5. Phylogenetic analysis based on core-genome SNPs demonstrated that the two genomes included in this study were clonally related to a T. mentagrophytes strain isolated in China in 2024. In conclusion, our study highlights the importance of genomic characterization in order to trace the epidemiology of dermatophytes worldwide and to characterize emerging strains. Full article

Friedrich Nietzsche can be an awkward topic for classicists and ancient philosophers, especially since an important part of his heavily critical philosophy begins as a reaction to, and critique of, his contemporary classical scholarship with which he was intimately familiar, being one of the most impressive ‘products’ of its development. Nietzsche was a thinker who in many ways turned the prevalent opinions about Greeks and contemporaries upside down, challenging his predecessors and successors with provocative readings of some of the most cherished philosophies in Western culture. This essay examines Nietzsche’s treatment of sophists—an important group of intellectuals whose reception had suffered greatly under the devastating judgement of Plato and Aristotle. While recent scholarship frequently regards sophists as philosophers, Nietzsche’s contemporaries were generally extremely dismissive of this group and regarded them in negative light as illegitimate thinkers and opponents to their contemporary ‘true’ philosophers (i.e., Socrates, Plato, and Aristotle). This paper traces two different moments in Nietzsche’s philosophical output that exhibit closer engagement with the sophists: the ‘early’ Nietzsche regards sophists as innovators in language and style, the ‘late’ Nietzsche sees them as countercultural revolutionaries. Despite the fact that in both stages, sophists are introduced as champions for ideas that are central to Nietzsche’s own philosophical preoccupations (the development of language, the overthrowing of values), his treatment of this group of intellectuals appears at first sight superficial and surprisingly unenthusiastic. The paper will examine our existing sources on Nietzsche’s treatment of the sophists and will suggest, ultimately, that his engagement with them was probably far more complex and multilayered than has been thus far assumed.

This study aimed to assess the incidence and distribution of dermatomycetes in patients at the Medical Military Academy (MMA) with suspected superficial skin infections over a five-year period (October 2017 to October 2022) and to analyze variations in fungal infections based on factors such as gender, body part, and time, particularly influenced by the COVID-19 pandemic. A total of 3993 samples were analyzed. Collected data were statistically analyzed with two tests. A total of 1048 samples were positive for fungal infections. Over the study period, Trichophyton mentagrophytes and Trichophyton rubrum were the predominant taxa, while Microsporum canis and Candida albicans were frequently observed. Statistical analysis indicated significant annual variations for T. mentagrophytes, T. rubrum, and M. canis, with monthly differences for T. mentagrophytes in June and August and M. canis in October and December. Gender-based analysis showed that T. rubrum and T. mentagrophytes were more common in males, while M. canis, C. albicans, Candida spp., and Geotrichum candidum were more prevalent in females. Analysis by body part revealed that Trichophyton rubrum and Microsporum canis showed significant differences between surface types. These findings can help improve diagnostic, therapeutic, and preventative strategies. Full article

As part of an implementation in the Peruvian textile industry, the use of different sources to obtain blue hues in alpaca fiber has taken on a prominent role. The present study investigated the optimization of the dyeing process of alpaca fibers using indigo carmine as dye. The methodology was based on a central composite design (CCD) and response surface methodology (RSM) with color strength (K/S) as response variable. The results demonstrate that the independent variables significantly affected the color strength (K/S). In this context, an increase in both mordant concentration (3.9887 g/L) and dyeing temperature (95 °C), coupled with lower exhaust time (30.0019 min), enhanced levels of superficial dye adsorption. Additionally, color fastness properties provided tolerable values according to the gray scale. In conclusion, the optimization of the dyeing process of alpaca fibers using indigo carmine enabled the achievement of a blue shade with satisfactory fastness properties in the fiber yarns.

Background/Objectives: Terbinafine has been the gold standard for the management of superficial fungal infections. The etiological agent generally is Trichophyton rubrum (T. rubrum); however, there has been increased reporting of a new terbinafine-resistant strain of the T. mentagrophytes complex (T. mentagrophytes ITS genotype VIII otherwise known as T. indotineae). Here, we review the epidemiology, clinical features, diagnosis, and treatment of T. rubrum and T. indotineae infections. Methods: We conducted a systematic literature search using PubMed, Embase (Ovid), and Web of Science, resulting in 83 qualified studies with data summarized for clinical features, antifungal susceptibility, and terbinafine resistance mechanisms and mutations. Results: Dermatophytosis is most commonly caused by T. rubrum; however, in certain parts of the world, especially in the Indian subcontinent, T. indotineae infections have been reported more frequently. The majority of T. rubrum isolates remain susceptible to terbinafine (over 60% of isolates show MIC₅₀ and MIC₉₀ < 0.5 µg/mL). In contrast, for T. indotineae, 30% of isolates exhibit MIC₅₀ ≥ 0.5 µg/mL and 80% exhibit MIC₉₀ ≥ 0.5 µg/mL. Frequently detected squalene epoxidase (SQLE) mutations in T. rubrum are Phe397Leu/Ile (41.6%) and Leu393Phe (20.8%); in T. indotineae, these include Phe397Leu (33.0%) and Ala448Thr (24.5%). Other potential terbinafine resistance mechanisms in T. rubrum and T. indotineae are discussed. Conclusions: T. rubrum generally remain susceptible in vitro to terbinafine in contrast to T. indotineae. The essential components of an effective antifungal stewardship emphasize accurate clinical and laboratory diagnosis, susceptibility testing, and appropriate antifungal therapy selection with a multidisciplinary approach.

All parts of Alocasia × amazonica (A. amazonica, Araceae) pose a toxicological risk due to oxalate production. Ingestion of the plant extract may cause multi-organ damage and fatal outcomes. Given the rarity of poisoning cases, its toxicological profile and systemic effects remain insufficiently characterized. This study aimed to investigate and report an appropriate approach to managing a patient intoxicated with A. amazonica (Araceae). A case of intentional self-poisoning with A. amazonica is presented. The patient, a 63-year-old woman, ingested approximately 200–300 mL of liquid prepared from the grated root of the plant. The initial clinical presentation involved localized injuries to the oral cavity and gastrointestinal tract, including severe pain, hoarseness, aphonia, dysphagia, mucosal erosions, and necrosis. Additional symptoms included hematinic vomiting, hemorrhagic diarrhea, and abdominal discomfort. These superficial and mucosal lesions resolved without the development of adhesions. Systemic effects comprised impaired consciousness indicative of encephalopathy, early metabolic acidosis, pulmonary edema with acute respiratory insufficiency, mild liver dysfunction, and hematuria. The therapeutic protocol for oral poisoning management was appropriate, leading to the patient’s discharge after 20 days of hospitalization. Full article

Introduction: Basal cell carcinoma (BCC) is the most frequently diagnosed skin cancer globally. Despite the well-established dermoscopic features of BCC, overlapping characteristics with other benign and malignant skin conditions cause challenges in differential diagnosis. Part III of this review highlights the role of dermoscopy in differential diagnosis, treatment planning, therapy monitoring and the integration of novel technologies including ultraviolet-induced fluorescence dermoscopy (UVFD) and optical super-high magnification dermoscopy (OSHMD). Methods: A search of the PubMed database was conducted for studies reporting on advances in the dermoscopic assessment of BCC, including differential diagnosis, treatment, monitoring and novel diagnostic technologies. Results: Even entities with well-defined dermoscopic features distinguishing them from BCC can sometimes mimic BCC. Additionally, rare lesions such as neurothekeoma, reticulohistiocytoma, solitary circumscribed neuroma, dermal leiomyosarcoma and various adnexal tumors often remain dermoscopically indistinguishable from BCC, which underscores the importance of histopathology as the diagnostic gold standard. Dermoscopy aids in delineating the tumor margins, optimizing Mohs micrographic surgery (MMS) and traditional excision. It may also help to monitor therapeutic effects by detecting the disappearance of BCC patterns, the presence of residual tumor or recurrences. Dermoscopy may aid in the prediction of therapeutic responses to imiquimod, photodynamic therapy or vismodegib. UVFD and OSHMD appear to be valuable complementary diagnostic techniques for detecting BCC. UVFD seems to be particularly valuable for the detection of small tumors (<5 mm), facial lesions and nodular or non-pigmented BCC subtypes, while OSHMD is useful for the assessment of superficial and non-pigmented BCCs. Three-dimensional total-body photography enhances diagnostic precision but, so far, only when used in combination with traditional dermoscopy. Conclusions: Dermoscopy is valuable for margin delineation, therapy monitoring and differential diagnosis but can be inconclusive, which highlights the role of histopathology as the gold standard. Modifications in dermoscopy technique may further enhance its accuracy. Full article

Background: Melanoma, a highly aggressive form of skin cancer, necessitates early detection to significantly improve survival rates. Traditional diagnostic techniques, such as white-light imaging (WLI), are effective but often struggle to differentiate between melanoma subtypes in their early stages. Methods: The emergence of the Spectrum-Aided Vison Enhancer (SAVE) offers a promising alternative by utilizing specific wavelength bands to enhance visual contrast in melanoma lesions. This technique facilitates greater differentiation between malignant and benign tissues, particularly in challenging cases. In this study, the efficacy of the SAVE is evaluated in detecting melanoma subtypes including acral lentiginous melanoma (ALM), melanoma in situ (MIS), nodular melanoma (NM), and superficial spreading melanoma (SSM) compared to WLI. Results: The findings demonstrated that the SAVE consistently outperforms WLI across various key metrics, including precision, recall, F1-scorw, and mAP, making it a more reliable tool for early melanoma detection using the four different machine learning methods YOLOv10, Faster RCNN, Scaled YOLOv4, and YOLOv7. Conclusions: The ability of the SAVE to capture subtle spectral differences offers clinicians a new avenue for improving diagnostic accuracy and patient outcomes. Full article

Non-destructive portable techniques for the analysis of cultural heritage items are essential for enhancing our understanding of these objects and providing valuable information for potential restoration interventions. This paper presents a combined use of pulsed thermography, X-ray fluorescence, and Raman spectroscopy to investigate the ancient bronze “Il Togato”, yielding complementary information concerning the techniques used for creating this artefact and its conservation status. Specifically, thermographic analysis has highlighted the presence of many patches of different size used for emending superficial cast defects, weldings used to connect parts separately cast to the main structure, cracks, and defects located in the bronze thickness. On the other hand, XRF provided information on the composition of the gilding which characterises the statue, and supplied an estimate of its thickness through the use of a stratification model. Additionally, Raman spectroscopy has been applied to identify corrosion products. The experimental results presented in the paper provide a comprehensive knowledge of the bronze under investigation and assess the effectiveness of the portable non-destructive techniques employed in the analysis.

Background and Objectives: The superficial femoral artery (SFA) can be injured during an intramedullary femoral nailing procedure with proximal and distal cross fixation, performed for proximal femoral fractures and intertrochanteric fractures. The aim of this study was to determine the safe and dangerous zones for the SFA during operative interventions on the femoral body in Turkish society and to define the relationship of these zones with femur length and sex. Materials and Methods: Using a computed tomography angiography, the relationship between the SFA and the medial shaft of the femur was examined in 160 limbs of 80 patients. The upper and lower cut points of the medial part of the SFA in the sagittal plane were defined. The distance of these points to the adductor tubercle was measured and the ratio of this value to the femur length was calculated. Results: The average distance of the SFA to the adductor tubercle in women was 214.2 ± 25.9 mm at the anterior border of the femur, while in men it was 229.8 ± 26.2 mm (p = 0.000). The danger zone length was 85 mm in women and 102 mm in men, and the difference was statistically significant (p = 0.000). The average distance of the SFA to the adductor tubercle at the anterior border of the femur was 223.1 ± 27.3 mm, the average femur length was 374.9 ± 30.2 mm, and a moderate correlation was found between them (r = 0.568). Conclusions: When determining the intraoperative danger zone using anatomical reference points in surgical approaches to the femur, variables such as sex and femur length should not be ignored.

Spanish teachers, in general, are committed, sensitised and in favour of integrating gender equality into their professional development. Despite this, the gender perspective has not been systematically integrated into the training of future teachers. One of the reasons for this is education professionals’ lack of knowledge about the most elementary constructs of gender mainstreaming. The present study explores primary school teachers’ perceptions and knowledge. To this end, it considers some critical elements of gender equality (gender, gender equality, the glass ceiling, and feminism). A qualitative and quantitative approach was adopted, and the methodological design was based on Grounded Theory. An intervention programme was designed to make students aware of and able to distinguish between these terms. Ninety-two prospective primary school teachers took part in the study. Of these, 69% were female, and 61% were between 17 and 18. To assess students’ perceptions of gender equality, students completed an initial and final questionnaire before and after the educational innovation. The findings show that future primary school teachers had superficial and limited knowledge about gender, gender equality, the glass ceiling, and feminism. In this regard, the design and implementation of transversal and innovative educational actions can help overcome these deficiencies. Full article

Introduction: Basal cell carcinoma (BCC) is the most common malignant skin tumor. While rarely fatal, it can cause local tissue damage. Part I of the review summarizes the dermoscopic features of BCC and the diagnostic accuracy of dermoscopy in the diagnosis of BCC. Methods: A search of the PubMed database was performed for studies reporting on the diagnostic accuracy of dermoscopy or dermoscopic findings in BCC, either pigmented or non-pigmented, located anywhere on the body, of any histopathologic subtype, size and at any age of onset. Results: BCC was found to present with a wide range of dermoscopic features, including white structures (shiny white lines, shiny white areas, rosettes), yellow structures (milia-like cysts, yellow lobular-like structures), multiple aggregated yellow-white globules (MAY globules), blue structures (blue ovoid nests), vascular structures (arborizing vessels, short fine telangiectasias), multiple small erosions/ulcerations, features of regression (pepper-like structures, white scar-like areas) and pigmented structures (spoke-wheel areas, maple leaf-like areas (MLLAs), blue/gray dots). Dermoscopy showed a sensitivity of 67.6–98.6% and a positive predictive value (PPV) of 85.9–97% in identifying BCC. The physician’s experience and training improve the accuracy, however, BCCs on the trunk and extremities, particularly of superficial subtypes, may still constitute a challenge. Conclusions: Dermoscopy, especially when performed by a trained physician, increases the accuracy of early BCC detection. Full article

Introduction: Basal cell carcinoma (BCC) is the most prevalent type of skin cancer worldwide. Despite its low metastatic potential, certain subtypes present an aggressive clinical course. Part II focuses on the different dermoscopic patterns observed in BCC, depending on the lesion subtype, its location on the body, the patient’s age, the size of the tumor, and skin phototype. Methods: A search of the PubMed database was conducted for studies reporting dermoscopic findings in BCC across all body locations, histopathologic subtypes, tumor sizes, ages of onset and skin phototypes. Results: There are no dermoscopic features indicative of a particular BCC subtype. However, arborizing, truncated or glomerular vessels, shiny white lines, ulceration, white areas, absence of pink zones and large blue-gray ovoid nests suggest high-risk BCCs (morpheaform, micronodular, infiltrative, basosquamous). Pigmented features can occur in all BCC types, though increased pigmentation indicates less aggressive subtypes (nodular, superficial, fibroepithelioma of Pinkus, adenoid). BCCs most commonly develop on the head, typically presenting as nodular and non-pigmented tumors. Those on the nose, eyes and ears may be more aggressive and prone to recurrence. On the trunk, BCCs are usually superficial and pigmented. Lower limb lesions often show polymorphous vessels rather than arborizing ones, which makes the dermoscopic diagnosis challenging. Dermoscopy aids early detection, with larger tumors exhibiting more established features but no size-specific patterns. Aggressive subtypes display similar dermoscopic findings regardless of size. Conclusions: Dermoscopy is a valuable tool for the early detection of BCC, though no specific dermoscopic features can definitively identify subtypes. High-risk BCCs can be suspected when distinct vascular and structural patterns are present, particularly in lesions located on the face, especially around the nose, eyes and ears, while pigmented features may indicate less aggressive subtypes.

The evolution of regional anesthesia techniques has markedly influenced the management of postoperative pain, particularly in thoracic surgery. As part of a multimodal analgesic approach, fascial plane blocks have gained prominence due to their efficacy in providing targeted analgesia with minimal systemic side effects. Among these, the superficial intercostal plane (SPIP) block and deep parasternal intercostal plane (DPIP) block are of notable interest. The aim of this study was to investigate the dye spread to the anterior chest wall space and its spread pathway through anatomical morphometric analyses on cadavers for single-injection and double-injection SPIP blocks versus DPIP blocks. In both qualitative and quantitative evaluations, the single-injection SPIP block with 10 mL of dye demonstrated a broader and more extensive spread compared to the double-injection SPIP block, which used 5 mL of dye per injection site (p < 0.05), and the DPIP block with 10 mL of dye (p < 0.05). All the blocks had a positive correlation between the distances from the sternum border and the area of dye spread, suggesting that the crucial role of volume in fascial blocks is that it significantly affects the opening of the fascial compartment, enabling optimal spread of the anesthetic. Adequate volume facilitates proper spread and diffusion across the fascial plane, ensuring more comprehensive fascia coverage and thus enhancing the block’s effectiveness. Finally, precise volume management is key to maximizing both efficacy and safety. Full article
