Abstract In the traditional fishing sector of Ecuador, integrating a gender perspective enhances sustainability and addresses climate change by recognizing the vital roles and knowledge of women in fisheries management. The objective of this study was to validate the content, comprehension, and construction of the designed questionnaire. Additionally, it is intended to identify perceptions of sustainability and climate change amongst women and men in fisheries, and compare their views on the dimensions of sustainability and climate change. The research implemented a questionnaire with a metrically satisfactory scale, providing information on how men and women perceive sustainability and climate change in the artisanal fishing sector. The data were collected by designing an ad hoc questionnaire denominated “Gender perception as regards sustainability and climate change” following a process in which the validity of the content (experts > 0.5823; Content Validity Ratio (CVR) > 6.1; Content Validity Index (CVI) > 0.852), decompression (pilot study, N = 30) and construct (KMO = 0.71) were analyzed. The results of the internal consistency reliability analysis indicated that the Likert scale had a high index of reliability, as evidenced by Cronbach’s Alpha coefficient of 0.70. This analysis provided evidence of the structure and validity of the scale, resulting in a reliable, integral, and short tool with which to measure perceptions of sustainability and climate change. The questionnaire was administered to 1464 people employed in the traditional fishing industry (17.14% women) in 40 fishing community ports near the coastal profile of Ecuador (Esmeraldas and Manabí). Most of those surveyed stated that the current traditional fishing quotas are not very sustainable in the long term (47.10%, n = 690) and that climate change may significantly negatively impact catch rates (50.30%, n = 736). Finally, the Wilcoxon test of tests confirmed that women had significantly more positive attitudes than men towards sustainability (3.03 ± 0.69) and climate change (3.35 ± 0.64).

Abstract Extreme heat events are more frequent and more intense globally due to climate change. The urban environment is an additional factor enhancing the effects of heat. Adults above 65 years old are especially at risk due to their poorer health, physiology and socio-economic situation. Yet, there is limited knowledge about their experiences of summer heat, their actual heat exposure and how they negotiate their thermal comfort through different adaptation practices. In conventional research on heat exposure and thermal comfort, very little attention is given to individual behaviour and subjective experiences. To understand how older adults feel the heat in the city we study their thermoception, which we conceptualise as an embodied knowledge about bodily sensations, thermal environments and adjustments to heat. This article stems from interdisciplinary research conducted in Warsaw and Madrid in the summers of 2021–2022. We combine and juxtapose data from ethnographic research and from physical measurements of temperature gathered in people’s homes, to show on a microscale how we can study and understand the diversity in individual heat exposure more holistically. We demonstrate that to understand the consequences of heat for vulnerable populations it is crucial to study thermoception, the subjective experiences of heat, in addition to analysing their thermal environments. With the use of a unique methodology, this article shows how similar weather conditions are experienced differently by people from the same cities, depending on the materiality of their dwellings, availability of cooling devices, as well as everyday habits and their individual bodies. We discuss the social, material and temporal adjustments participants made to deal with heat, to showcase their agency in affecting their individual heat exposure. The article emphasises the role of social sciences and qualitative methods in research on individual heat exposure and argues for the co-production of knowledge on the topic.

Abstract Alternative Splicing (AS) programs serve as instructive signals of cell type specificity, particularly within the brain, which comprises dozens of molecularly and functionally distinct cell types. Among them, retinal photoreceptors stand out due to their unique transcriptome, making them a particularly well-suited system for studying how AS shapes cell type-specific molecular functions. Here, we use the Splicing Regulatory State (SRS) as a novel framework to discuss the splicing factors governing the unique AS pattern of photoreceptors, and how this pattern may aid in the specification of their highly specialized sensory cilia. In addition, we discuss how other sensory cells with ciliated structures, for which data is much scarcer, also rely on specific SRSs to implement a proteome specialized in the detection of sensory stimuli. By reviewing the general rules of cell type- and tissue-specific AS programs, firstly in the brain and subsequently in specialized sensory neurons, we propose a novel paradigm on how SRSs are established and how they can diversify. Finally, we illustrate how SRSs shape the outcome of mutations in splicing factors to produce cell type-specific phenotypes that can lead to various human diseases.

Abstract The contemporary media narratives frequently exhibit significant contradictions due to the influence of diverse interests. In this context, the framing of information assumes critical importance in shaping consumer opinions, necessitating a comprehensive examination of its management. This article investigates the portrayal of crises in the agri-food sector within the mass media when not anchored in objective and verifiable facts, thereby exerting a consequential impact on the sector’s reputation and public image. Specifically, a detailed analysis is conducted on the greenhouse horticulture sector in southeast Spain, recognized as the primary European supplier. Examination of these news items uncovers a discernible bias in the disseminated information, resulting in an information asymmetry between farmers and consumers. As a remedy for the affected sector, the current study advocates the implementation of a proactive crisis detection and management model grounded in the development and dissemination of verifiable information.

Abstract Triple‐negative breast cancer (TNBC) often develops resistance to single‐agent treatment, which can be circumvented using targeted combinatorial approaches. Here, we demonstrate that the simultaneous inhibition of LOXL2 and BRD4 synergistically limits TNBC proliferation in vitro and in vivo. Mechanistically, LOXL2 interacts in the nucleus with the short isoform of BRD4 (BRD4S), MED1, and the cell cycle transcriptional regulator B‐MyB. These interactions sustain the formation of BRD4 and MED1 nuclear transcriptional foci and control cell cycle progression at the gene expression level. The pharmacological co‐inhibition of LOXL2 and BRD4 reduces BRD4 nuclear foci, BRD4‐MED1 colocalization, and the transcription of cell cycle genes, thus suppressing TNBC cell proliferation. Targeting the interaction between BRD4S and LOXL2 could be a starting point for the development of new anticancer strategies for the treatment of TNBC.

Abstract Translation efficiency has been mainly studied by ribosome profiling, which only provides an incomplete picture of translation kinetics. Here, we integrated the absolute quantifications of tRNAs, mRNAs, RNA half‐lives, proteins, and protein half‐lives with ribosome densities and derived the initiation and elongation rates for 475 genes (67% of all genes), 73 with high precision, in the bacterium Mycoplasma pneumoniae (Mpn). We found that, although the initiation rate varied over 160‐fold among genes, most of the known factors had little impact on translation efficiency. Local codon elongation rates could not be fully explained by the adaptation to tRNA abundances, which varied over 100‐fold among tRNA isoacceptors. We provide a comprehensive quantitative view of translation efficiency, which suggests the existence of unidentified mechanisms of translational regulation in Mpn.

Abstract Interleukin‐10 (IL‐10) is an anti‐inflammatory cytokine that is active as a swapped domain dimer and is used in bacterial therapy of gut inflammation. IL‐10 can be used as treatment of a wide range of pulmonary diseases. Here we have developed a non‐pathogenic chassis (CV8) of the human lung bacterium Mycoplasma pneumoniae (MPN) to treat lung diseases. We find that IL‐10 expression by MPN has a limited impact on the lung inflammatory response in mice. To solve these issues, we rationally designed a single‐chain IL‐10 (SC‐IL10) with or without surface mutations, using our protein design software (ModelX and FoldX). As compared to the IL‐10 WT, the designed SC‐IL10 molecules increase the effective expression in MPN four‐fold, and the activity in mouse and human cell lines between 10 and 60 times, depending on the cell line. The SC‐IL10 molecules expressed in the mouse lung by CV8 in vivo have a powerful anti‐inflammatory effect on Pseudomonas aeruginosa lung infection. This rational design strategy could be used to other molecules with immunomodulatory properties used in bacterial therapy.

Introduction: Metabolic and bariatric surgery (MBS) has experienced considerable growth, addressing the challenges of obesity and its complications. The lack of a comprehensive bibliometric analysis in Latin America motivates this study, highlighting the need to understand the evolution of research in this area and its impact on clinical decision-making and health policies. Methodology: A cross-sectional bibliometric study was carried out using the Scopus database. A structured search strategy was designed to identify articles related to bariatric surgery with authors affiliated with Latin American countries. Inclusion and exclusion criteria were applied, followed by a descriptive and bibliometric analysis of the scientific production found. Results: A total of 3553 documents published between 1991 and 2024 were included. There was an annual growth of 11%, with an average age of documents of 7.5 years. A concentration was observed in some countries, notably Brazil, Mexico, and Chile. Although scientific output increased, the average number of citations per article showed a downward trend since 2003. Discussion: Despite the growth in scientific production, the quality and relevance of research is questioned, especially given the decrease in the impact received. It highlights the lack of meaningful regional collaboration, which could limit the sharing of knowledge and resources. Questions are raised about gaps in research capacity and the economic and development implications are discussed. Conclusions: This study provides valuable information to strengthen future research in bariatric surgery in Latin America. It highlights the importance of promoting regional and international collaboration and improving research training in countries with less participation. Clinical intervention strategies can benefit from better understanding research trends and adopting evidence-based practices in a more informed manner. [ABSTRACT FROM AUTHOR]

Plants and microorganisms establish beneficial associations that can improve their development and growth. Recently, it has been demonstrated that bacteria isolated from the skin of amphibians can contribute to plant growth and defense. However, the molecular mechanisms involved in the beneficial effect for the host are still unclear. In this work, we explored whether bacteria isolated from three tropical frogs species can contribute to plant growth. After a wide screening, we identified three bacterial strains with high biostimulant potential, capable of modifying the root structure of Arabidopsis thaliana plants. In addition, applying individual bacterial cultures to Solanum lycopersicum plants induced an increase in their growth. To understand the effect that these microorganisms have over the host plant, we analysed the transcriptomic profile of A. thaliana during the interaction with the C32I bacterium, demonstrating that the presence of the bacteria elicits a transcriptional response associated to plant hormone biosynthesis. Our results show that amphibian skin bacteria can function as biostimulants to improve agricultural crops growth and development by modifying the plant transcriptomic responses.

Abstract Several promising plasma biomarkers for Alzheimer's disease have been recently developed, but their neuropathological correlates have not yet been fully determined. To investigate and compare independent associations between multiple plasma biomarkers (p‐tau181, p‐tau217, p‐tau231, Aβ42/40, GFAP, and NfL) and neuropathologic measures of amyloid and tau, we included 105 participants from the Arizona Study of Aging and Neurodegenerative Disorders (AZSAND) with antemortem plasma samples and a postmortem neuropathological exam, 48 of whom had longitudinal p‐tau217 and p‐tau181. When simultaneously including plaque and tangle loads, the Aβ42/40 ratio and p‐tau231 were only associated with plaques (ρAβ42/40[95%CI] = −0.53[−0.65, −0.35], ρp‐tau231[95%CI] = 0.28[0.10, 0.43]), GFAP was only associated with tangles (ρGFAP[95%CI] = 0.39[0.17, 0.57]), and p‐tau217 and p‐tau181 were associated with both plaques (ρp‐tau217[95%CI] = 0.40[0.21, 0.56], ρp‐tau181[95%CI] = 0.36[0.15, 0.50]) and tangles (ρp‐tau217[95%CI] = 0.52[0.34, 0.66]; ρp‐tau181[95%CI] = 0.36[0.17, 0.52]). A model combining p‐tau217 and the Aβ42/40 ratio showed the highest accuracy for predicting the presence of Alzheimer's disease neuropathological change (ADNC, AUC[95%CI] = 0.89[0.82, 0.96]) and plaque load (R2 = 0.55), while p‐tau217 alone was optimal for predicting tangle load (R2 = 0.45). Our results suggest that high‐performing assays of plasma p‐tau217 and Aβ42/40 might be an optimal combination to assess Alzheimer's‐related pathology in vivo.

Building on traditional emulsion polymerization research, which continues to yield results up to the present day, techniques have emerged to produce hybrid materials. One such technique is Pickering emulsion polymerization, with numerous industrial applications. Despite a growing interest in Pickering emulsion polymerization, the intrinsic mechanisms involved have been based mainly on the findings of classical emulsion polymerization. In this work, by relying on a minimum of assumptions and using a simple model and experimental data on conversion and particle size, we obtain information about the prevailing mechanisms. More specifically, we present four main findings based on data reported previously in the literature. First, in contrast to the three rate-of-reaction intervals reported in classical emulsion polymerization, the integro-differential method yielded only two rate-of-reaction intervals against conversion. Second, a master curve is constructed by plotting the reaction rate against overall conversion, showing a maximum of approximately 55% conversion. Third, despite having a semicontinuous process, monomer concentration inside the particles is not constant. Finally, particle density is a strong function of the Pickering agent concentration, where two fitting parameters (nucleation and coagulation) allowed an accurate description for the particle number time evolution. Both parameters showed a power-law dependence with clay concentration. [ABSTRACT FROM AUTHOR]

The present work investigated new sustainable opportunities for wood protection against xylophagous organisms (cellulolytic fungi and termites) based on the use of natural bioactive compounds present in Milicia excelsa wood and Nerium oleander bark. To achieve this, solid–liquid extractions by ethanol were carried out, obtaining extraction yields of 5.47 ± 0.78% for the extract of M. excelsa and 21.88 ± 0.53% for N. oleander. Gas chromatography coupled with mass spectrometry analyses were carried out to evaluate the chemical composition of both extracts, showing interesting compounds with biological activity such as pyrogallol, 4-acetylresorcinol, karanjin and scopoletin. Likewise, an evaluation of the cellulolytic capacity of different wood-isolated fungi (Aspergillus flavus, Penicillium chrysogenum, Trichoderma longibrachiatum, Mucor circinelloides and Mucor fragilis) was carried out through two screenings, based on their growth rate in carboxymethyl cellulose agar media, and their cellulose-degrading ability via filter paper rupture, being T. longibrachiatum the fungus with the highest growth rate in both substrates. Finally, a protective treatment for pine wood (Pinus sp.) was designed by using the ethanolic extracts separately and combined, respectively, against T. longibrachiatum and Reticulitermes grassei, comparing in both cases the biotic damage with a control. The results demonstrated that the impregnation significantly reduced T. longibrachiatum biomass consumption by over 70% for all treatments. Additionally, the M. excelsa impregnation notably decreased termite activity, with a 81% reduction in the long-term assays. [ABSTRACT FROM AUTHOR]

Given an extendible spacetime one may ask how much, if any, uniqueness can in general be expected of the extension. Locally, this question was considered and comprehensively answered in a recent paper of Sbierski [22], where he obtains local uniqueness results for anchored spacetime extensions of similar character to earlier work for conformal boundaries by Chruściel [2]. Globally, it is known that non-uniqueness can arise from timelike geodesics behaving pathologically in the sense that there exist points along two distinct timelike geodesics which become arbitrarily close to each other interspersed with points which do not approach each other. We show that this is in some sense the only obstruction to uniqueness of maximal future boundaries: Working with extensions that are manifolds with boundary we prove that, under suitable assumptions on the regularity of the considered extensions and excluding the existence of such "intertwined timelike geodesics", extendible spacetimes admit a unique maximal future boundary extension. This is analogous to results of Chruściel for the conformal boundary. [ABSTRACT FROM AUTHOR]

The present work has experimentally determined the specific fracture energy of the hardwood species silver birch (Betula pendula), which in recent times has caught increased attention for utilization in structural applications. The single-edge-notched beam loaded in three-point-bending was utilized for evaluating the fracture energy with the work-of-fracture method. In addition to birch, Norway spruce (Picea abies) was utilized as a reference material. The effect of two different geometries of the fracture area for each species was evaluated—one triangular and one rectangular fracture area. It should be noted that the geometry of the fracture area did influence the evaluated fracture energy, and this influence was not consistent between species. This was likely in part due to manufacturing difficulties with the triangular fracture area. In addition to the experimental testing, a numerical 2d-model including linear strain-softening behavior was used for comparative simulations. The numerical 2d-models showed reasonable agreement with the experimental results regarding the global load vs. displacement response, despite their relative simple nature. The specific fracture energy for the spruce specimens was evaluated to 221 J/ m 2 and for the birch specimens to 656 J/ m 2 . Consequently, the present work implies a marked increase in specific fracture energy for birch, compared to spruce. This increase in specific fracture energy could potentially have a large influence on the failure behavior of birch when used in structural applications which is something that needs to be considered in future work.

Purpose: Peripheral helper T (Tph) cells have an important role in the induction of humoral immune responses and autoantibody production. Accordingly, it is feasible that this lymphocyte subset has a relevant role in the pathogenesis of autoimmune thyroid diseases (AITD). In this study we aim to analyze the levels and function of Tph cells in blood samples from patients with AITD. Methods: We performed an observational study with cases and controls. Blood samples were obtained from nineteen patients with Hashimoto's thyroiditis (HT), twenty-four with Graves' disease (GD), and fifteen healthy controls. In addition, the levels of follicular T helper (Tfh) cells and Tph cells, the release of interleukin-21 (IL-21) by these lymphocytes and the number of plasmablasts were analyzed by multi-parametric flow cytometry analyses. Results: Increased percentages of Tfh and Tph lymphocytes were detected in patients with HT and GD. Furthermore, an enhanced synthesis of the cytokine IL-21 by these cells was observed. Accordingly, we detected significant higher percentages of plasmablasts in patients with GD, and these values tended to be also higher in HT patients. Moreover, significant positive associations were observed between the levels of Tfh or Tph and the number of plasmablast or anti-TSHR Ab titers in patients with AITD. Conclusion: Our data suggest that Tph lymphocytes may have a relevant role in the pathogenesis of AITD. [ABSTRACT FROM AUTHOR]

This article examines the state of research on sport entrepreneurship, with a particular focus on the intersection of entrepreneurship, innovation, and creativity in sport management. Sport is an increasingly important sector of the global economy, yet little attention has been given to the role of entrepreneurship in its development. This article argues that entrepreneurship, innovation, and creativity are crucial drivers of change, innovation, and employment in sport and that sport entrepreneurship is an emerging but unorganized stream of business research. To better understand the relationship between these research fields, we performed a study that combined a systematic review and a bibliometric analysis. This article presents thematic shifts in the field of sport entrepreneurship, innovation, and creativity. It proposes an integrated model of sport entrepreneurship, offering novel perspectives that contribute to the field. Furthermore, the article addresses the lack of research on creativity, sustainability, and the sport entrepreneur, charting underexplored territories. Overall, this article provides a comprehensive overview of current research on sport entrepreneurship and identifies key areas for future investigation. [ABSTRACT FROM AUTHOR]

Introduction: Diffuse alveolar hemorrhage (DAH) is a rare complication with high mortality in patients with systemic lupus erythematosus (SLE). Early diagnosis and treatment are essential to improve patient prognosis. To determine the characteristics of patients with DAH and their mortality in a Spanish cohort of patients with SLE. Methods: Patients from the RELESSER (Spanish Society of Rheumatology Lupus Register) who had had at least one confirmed episode of DAH were included. Epidemiological, clinical, and laboratory characteristics were analyzed. Results: 4024 patients were included in the RELESSER register, 37 (0.9%), had at least one recorded episode of DAH. Only further data for 14 patients could be analyzed. In total, 92.9% were women, and for 4 (28.6%) DAH coincided with the debut of SLE. More than 80% of patients had renal involvement and thrombocytopenia. The most frequent manifestations were dyspnea (85.7%) and hypoxemia (100%), with the classic triad of hemoptysis, anemia and pulmonary infiltrates, appearing in 6 (46.2%) patients. The most frequently used treatments were glucocorticoids (85.7%) and cyclophosphamide (69.2%); plasmapheresis was utilized in 5 patients (35.7%) and 8, (57.1%) received intravenous immunoglobulins; 12 (85.7%) patients required admission to the ICU and 5 (35.7%) died. Tobacco use, history of lupus nephritis (LN), concomitant infection, and treatment with cyclophosphamide were more frequent in patients who died. Conclusions: DAH is rare in patients with SLE; in up to one-third of patients, it may appear at the onset of the disease. Some factors, such as smoking, a history of LN, treatment with cyclophosphamide, or concomitant infection, are more prevalent in patients with an unfavorable outcome. [ABSTRACT FROM AUTHOR]

Studies have shown that horses are sensitive to human attentional cues. Also, there is some evidence that they might be able to infer the knowledge state of a human and communicate intentionally with us. However, this ability is not fully characterized and certain behaviors, like gaze, asymmetric ears position or vocalizations, which could work as attention-getting behaviors, have been scarcely studied in this context. The aim of the present study was to assess whether horses' gaze toward a person, asymmetric ears position and vocalizations are subject to audience effects and adjust to human attentional cues, which would suggest a communicative function. For this purpose, we adapted a protocol used with domestic dogs [Kaminski et al. 2017] and observed horses' spontaneous behavior (gaze, asymmetric ears position and vocalizations) in the presence of a human holding and not holding food in an attentive position (facing the horse with open eyes) and in a non-attentive position (with her back turned towards the horse). We found significant evidence of horses being sensitive to human attentional cues (reflected in the horses' gaze duration and asymmetric position of the ears), but not of intentional communication towards humans.

Oculopharyngodistal myopathy (OPDM) is an inherited myopathy manifesting with ptosis, dysphagia and distal weakness. Pathologically it is characterised by rimmed vacuoles and intranuclear inclusions on muscle biopsy. In recent years CGG • CCG repeat expansion in four different genes were identified in OPDM individuals in Asian populations. None of these have been found in affected individuals of non-Asian ancestry. In this study we describe the identification of CCG expansions in ABCD3, ranging from 118 to 694 repeats, in 35 affected individuals across eight unrelated OPDM families of European ancestry. ABCD3 transcript appears upregulated in fibroblasts and skeletal muscle from OPDM individuals, suggesting a potential role of over-expression of CCG repeat containing ABCD3 transcript in progressive skeletal muscle degeneration. The study provides further evidence of the role of non-coding repeat expansions in unsolved neuromuscular diseases and strengthens the association between the CGG • CCG repeat motif and a specific pattern of muscle weakness. A significant proportion of individuals with inherited neuromuscular disease do not receive a genetic diagnosis. Here, the authors establish CCG expansions in the 5' untranslated region of ABCD3 as a cause of oculopharyngodistal myopathy (OPDM) in individuals of European ancestry and identify increased expression of expansion-containing ABCD3 transcripts as a possible disease mechanism underlying muscle degeneration.

Using the administrative records of the Spanish Public Employment Service for the period 2018–2019, we analysed the impact of participation in job search assistance and training programmes on the chances of unemployed jobseekers finding employment, as well as the quality of the job obtained. Propensity score matching techniques were used to evaluate the effectiveness of these programmes. We found that participation exerted a positive and significant differential effect on the probability of transition from unemployment to employment and on the probability of finding a job of intermediate quality compared to non-participation. This positive impact was largely due to the effect of training programmes, the magnitude of which persisted even as the period elapsed between participation and exit towards employment increased, whereas job search assistance was less effective over time. The positive influence of participation appeared to be more intense for specific socioeconomic groups. [ABSTRACT FROM AUTHOR]

Growing evidence supports that early- or middle-life traumatic brain injury (TBI) is a risk factor for developing Alzheimer's disease (AD) and AD-related dementia (ADRD). Nevertheless, the molecular mechanisms underlying TBI-induced AD-like pathology and cognitive deficits remain unclear. In this study, we found that a single TBI (induced by controlled cortical impact) reduced the expression of BCL2-associated athanogene 3 (BAG3) in neurons and oligodendrocytes, which is associated with decreased proteins related to the autophagy-lysosome pathway (ALP) and increased hyperphosphorylated tau (ptau) accumulation in excitatory neurons and oligodendrocytes, gliosis, synaptic dysfunction, and cognitive deficits in wild-type (WT) and human tau knock-in (hTKI) mice. These pathological changes were also found in human cases with a TBI history and exaggerated in human AD cases with TBI. The knockdown of BAG3 significantly inhibited autophagic flux, while overexpression of BAG3 significantly increased it in vitro. Specific overexpression of neuronal BAG3 in the hippocampus attenuated AD-like pathology and cognitive deficits induced by TBI in hTKI mice, which is associated with increased ALP-related proteins. Our data suggest that targeting neuronal BAG3 may be a therapeutic strategy for preventing or reducing AD-like pathology and cognitive deficits induced by TBI. [ABSTRACT FROM AUTHOR]

Urban noise can potentially disturb the acoustic signals of animals inhabiting urban areas. Although a wide variety of noises from different sources is common in cities, the impact of non-engine noise on animal calls is less studied. In a natural experiment, we evaluated the effect of different urban noises on the advertisement calls of urban frogs (Eleutherodactylus nitidus) in the metropolitan area of Puebla, Mexico. We recorded and analyzed 672 advertisement calls from 28 male frogs and the corresponding environmental noises from three distinct localities. Our analysis focused on four acoustic properties of the calls: inter-call interval, call duration, dominant frequency, and call amplitude. To standardize the amplitude measurements of sound pressure levels produced by noise and frog calls, we employed a practical approach using a reference signal for calibration. We treated the longitudinal data of different noises occurring before, during, and after advertisement calls as repeated measures within the urban locations. During our samplings, frogs called amidst spontaneous urban noises, including dog barking, fireworks, and vehicle engine sounds. Our results indicate that vehicle engine sounds and dog barking do not cause significant distortions in the calls of these urban frogs. However, we observed slight variations in the dominant frequency of calls, decreasing by 11 Hz, during and after fireworks. Given the observed plasticity of E. nitidus in response to noise, urban noises may not pose a severe problem for this urban frog. [ABSTRACT FROM AUTHOR]

In the universe, there are up to 2 trillion galaxies with different features ranging from the number of stars, light spectrum, age, or visual appearance. Consequently, automatic classifiers are required to perform this task; furthermore, as shown by some related works, while greater the number of classes considered, the performance of the classifiers tends to decrease. This work is focused on the morphological classification of galaxies. They can be associated with a subset of 10 classes arranged in a hierarchy derived from the Hubble sequence. The proposed method, Bayesian and Convolutional Neural Networks (BCNN), is composed of two main modules. The first module is a convolutional neural network trained with the images of galaxies, and its predictions feed the second module. The second module is a Bayesian network that evaluates the hierarchy and helps to improve the prediction accuracy by combining the predictions of the first module through probabilistic inference over the Bayesian network. A collection of galaxies sourced from the Principal Galaxies Catalog and the APM Equatorial Catalogue of Galaxies are used to perform the experiments. The results show that BCNN performed better than five CNNs in multiple evaluation measures, reaching the scores 83% in hierarchical F-measure, 78% in accuracy, and 67% in exact match evaluation.

Ischemic stroke is a leading cause of death and disability worldwide. Inflammatory response after stroke determines the outcome of ischemic injury. A recent study has reported an efficient method, epidural arterial implantation (EAI), for accelerating interstitial fluid (ISF) drainage, which provides a promising strategy to clear pro-inflammatory cytokines in the brain extracellular space (ECS). In this study, the method of EAI was modified (m-EAI) to control its function of accelerating the ISF drainage at different time points following ischemic attack. The neuroprotective effect of m-EAI on ischemic stroke was evaluated with the transient middle cerebral artery occlusion (tMCAO) rat model. The results demonstrated the accumulation of IL-1β, IL-6, and TNF-α was significantly decreased by activating m-EAI at 7 d before and immediately after ischemic attack in tMCAO rats, accompanied with decreased infarct volume and improved neurological function. This study consolidates the hypothesis of exacerbated ischemic damage by inflammatory response and provides a new perspective to treat encephalopathy via brain ECS. Further research is essential to investigate whether m-EAI combined with neuroprotective drugs could enhance the therapeutic effect on ischemic stroke. [ABSTRACT FROM AUTHOR]

Purpose: High resolution imagery from unmanned aerial vehicles (UAVs) has been established as an important source of information to perform precise irrigation practices, notably relevant for high value crops often present in semi-arid regions such as vineyards. Many studies have shown the utility of thermal infrared (TIR) sensors to estimate canopy temperature to inform on vine physiological status, while visible-near infrared (VNIR) imagery and 3D point clouds derived from red–green–blue (RGB) photogrammetry have also shown great promise to better monitor within-field canopy traits to support agronomic practices. Indeed, grapevines react to water stress through a series of physiological and growth responses, which may occur at different spatio-temporal scales. As such, this study aimed to evaluate the application of TIR, VNIR and RGB sensors onboard UAVs to track vine water stress over various phenological periods in an experimental vineyard imposed with three different irrigation regimes. Methods: A total of twelve UAV overpasses were performed in 2022 and 2023 where in situ physiological proxies, such as stomatal conductance (gs), leaf (Ψleaf) and stem (Ψstem) water potential, and canopy traits, such as LAI, were collected during each UAV overpass. Linear and non-linear models were trained and evaluated against in-situ measurements. Results: Results revealed the importance of TIR variables to estimate physiological proxies (gs, Ψleaf, Ψstem) while VNIR and 3D variables were critical to estimate LAI. Both VNIR and 3D variables were largely uncorrelated to water stress proxies and demonstrated less importance in the trained empirical models. However, models using all three variable types (TIR, VNIR, 3D) were consistently the most effective to track water stress, highlighting the advantage of combining vine characteristics related to physiology, structure and growth to monitor vegetation water status throughout the vine growth period. Conclusion: This study highlights the utility of combining such UAV-based variables to establish empirical models that correlated well with field-level water stress proxies, demonstrating large potential to support agronomic practices or even to be ingested in physically-based models to estimate vine water demand and transpiration.

Objective: Progressive pneumoperitoneum (PPP) is useful tool in the preparation of patients with loss of domain hernias (LODH). The purpose of this observational retrospective study was to report our experience in the management of complications associated with the PPP procedure after treating 180 patients with LODH and to report preventive measures to avoid them. Methods: Of the 971 patients with a ventral incisional hernia operated on between June 2012 and July 2022, 180 consecutive patients with LODH were retrospectively analysed. Diameters of abdominal cavity, and volumes of incisional hernia and abdominal cavity were calculated from CT scan, based on the modified index of Tanaka. Complications related to the PPP procedure (catheter placement and following insufflations of air) were recorded by Clavien–Dindo classification. Results: Complications associated to PPP were 26.6%. No complications occurred during the administration of botulinum toxin (BT). Eighteen patients (10% of 180 patients) developed subcutaneous emphysema during the last days of the insufflations; there were 2 accidental perforations of the small bowel and four punctures with liver and splenic hematomas, detected during catheter placement; a laparotomy, however, was not needed because it was solved with conservative treatment. We diagnosed it as a peritoneum-cutaneous fistula due to the cutaneous atrophy secondary to chronic eventration. Conclusion: PPP is a safe technique well tolerated by patients, although at the cost of some specific complications. Hernia surgeons must understand these complications to prevent them and to inform the LODH patient about their existence. [ABSTRACT FROM AUTHOR]

The aim of this study was to investigate the measures of displacement, time and velocity of hyoid bone movement in female thyroidectomy patients. Fifty-eight ultrasound videos of 29 women during swallowing were analyzed. The sample was divided into experimental group (EG), composed of 12 women following total or partial thyroidectomy; and control group (CG) of 17 healthy women. The kinematic measures of displacement, time and velocity of hyoid bone displacement were tracked during swallowing of 10 ml of liquid (water) and 10 ml of thickened liquid (honey) in both groups for comparisons. Additional analysis included bolus consistency effect and relationship with clinical characteristics. Ultrasound videos were analyzed according to a standardized protocol using ImageJ software. Displacement, time and velocity of hyoid movement during swallowing of 10 ml of liquid or thickened liquid were not statistically different between female thyroidectomy patients and healthy women. There is no bolus consistency effect on kinematic measures in both groups, but among thyroidectomy patients, velocity of hyoid bone movement is significantly faster in those with swallowing complaints.

Previous studies have suggested a negative impact of steroids on the efficacy of immune checkpoint inhibitors (ICI), but how this effect is modulated by the dosage and time of administration is yet to be clarified. We have performed a retrospective analysis of 475 patients with advanced solid tumors treated with ICI as monotherapy from 2015 to 2022. Data regarding immune-related adverse events (irAEs) and clinical outcomes were collected. For each patient, the daily steroid dose (in mg/kg of prednisone) was registered until disease progression or death. The impact of cumulative doses on response rates and survival outcomes was analyzed within different periods. The objective response rate (ORR) was significantly lower among patients exposed to steroids within 30 days before the first cycle of ICI (C1) (20.3% vs. 36.7%, p < 0.01) and within the first 90 days of treatment (25.7% vs. 37.7%, p = 0.01). This negative association was confirmed by multivariable analysis. Higher mean steroid doses were observed among non-responders, and cumulative doses were inversely correlated with the disease control rate (DCR) around ICI initiation. Remarkably, poorer outcomes were observed even in patients belonging to the lowest dose quartile compared to the steroid-naïve population. The exposure to steroids after 6 months of ICI was not associated with worse survival outcomes. Our results suggest that the potential impact of steroids on ICI efficacy may be time-dependent, prevailing around ICI initiation, and dose-dependent, with modulation of neutrophil-to-lymphocyte ratio as a possible underlying mechanism.

Leopardus wiedii and Leopardus pardalis are endangered small felids. Its main altitudinal range expands from sea level to 1,500 m. Camera traps were placed in the Matawi Indigenous Park on the Nevado de Toluca Volcano. Photographic records were obtained of L. wiedii at 3,207 masl and of L. pardalis at 3,307 masl. This is the highest altitudinal record for margay in its distribution, and for ocelot is the highest in the northern hemisphere. [ABSTRACT FROM AUTHOR]

Purpose: HER2 overexpression in breast cancer correlates with poor outcomes. The incorporation of Trastuzumab into the treatment regimen has notably improved patient prognoses. However, cardiotoxicity emerges in approximately 20% of patients treated with the drug. This study aims to investigate the association between the HER2 655 A > G polymorphism, Trastuzumab-induced cardiotoxicity, and patient survival. Methods: The study involved 88 patients treated with Trastuzumab. Cardiotoxicity, defined as a reduction in left ventricular ejection fraction (LVEF) from baseline or the emergence of clinical signs of congestive heart failure, was identified during treatment follow-up. Genotyping of HER2 655 A > G employed TaqMan SNP technology. Results: Genotype frequencies of HER2/neu 655 (53 AA, 32 AG, and 3 GG) were consistent with Hardy–Weinberg equilibrium. No significant differences were observed in mean baseline LVEF between patients who developed cardiotoxicity and those who did not. Within these groups, neither AA nor AG genotypes showed an association with changes in mean baseline or reduced LVEF levels. Logistic regression analysis, adjusted for hormonal status and anthracycline treatment, revealed that AG genotype carriers face a significantly higher risk of cardiotoxicity compared to AA carriers (OR = 4.42; p = 0.037). No association was found between the HER2/neu 655 A > G polymorphism and disease-free or overall survival, regardless of whether the data was adjusted for stage or not. Conclusion: HER2 655 A > G polymorphism is significantly linked to an increased risk of Trastuzumab-induced cardiotoxicity but does not correlate with variations in disease-free survival or overall survival rates.

In 1937, Travassos described a new species of nematode in the genus Longistriata Schulz, 1926. He referred to it seven times as L. zetta in the main text, but also five times as L. zeta in the figure legends. This nominal species is currently assigned to the genus Guerrerostrongylus Sutton and Durette-Desset, 1991. The complete bibliography referring to this species from 1937 to date comprises only 22 works. Although the spelling ‘zetta’ has prevailed since 2011, the correct original spelling of its specific name remains unsettled. Acting as First Revisers under Articles 24.2.3 and 32.2.1 of the International Code of Zoological Nomenclature, we hereby choose ‘zeta’ as the correct original spelling of the specific name of this nematode, thus rendering ‘zetta’ an unavailable incorrect spelling. In making this choice, we have taken into account Travassos’ obvious intention to name the species after the sixth letter of the Greek alphabet and the longer use of the spelling ‘zeta’ in the relevant literature, especially in those works in which ‘zeta’ (never ‘zetta’) was first combined with other generic names. We believe that standardizing the use of the spelling ‘zeta’ as the correct original spelling is the best way to stabilize this name. [ABSTRACT FROM AUTHOR]

The sea urchin Diadema africanum is a macro-herbivore found in the rocky reef systems of the West African region and Macaronesian archipelagos. Over several decades, high densities of this species have generated marine barrens in certain areas at the Canary Islands. In contrast, more recently, during the last few years, the species has suffered mass mortality events that continue to the present day. In this study, we used 9,109 Single Nucleotide Polymorphisms (SNPs) and a fragment of a mitochondrial gene to evaluate the species' population structure, effects of mass mortalities on its diversity, and potential local adaptation across the Canary Islands and Cabo Verde. Our research provides compelling evidence of low genomic diversity and homogeneity across the studied area for neutral markers, along with recent demographic fluctuations. The high connectivity among distant areas likely allows a rapid recovering of the populations from local mortality events. Interestingly, we also observed genomic sub-structure from 405 SNPs identified as candidate loci under selection for seawater temperature. The lack of divergence among distant sites and the low diversity found can be attributed to the species' divergence from a small ancestral genomic pool, followed by a contemporary demographic expansion, and ongoinggene flow.

Purpose: Surgery close to or in contact with the ventricular system is challenging due to the complications. We sought to evaluate the effectiveness and safety of TachoSil® as a ventricular sealant in preventing complications after cranial surgery with an open ventricular system (OVS). Methods: This is a single-center and prospective cohort study We included patients who underwent elective surgery for supratentorial craniotomy and periventricular pathology between December 2020 and November 2023. We registered surgical complications arising from CSF dynamics (such as percutaneous cerebrospinal fluid (CSF) leakage, hydrocephalus, pseudomeningocele), infections, and other complications (postsurgical hematoma) adverse drug reactions (ADRs), reintervention or hospital readmission up to 90 days after surgery. Results: Forty interventions were performed on 39 patients, whose median age was 56 years. Eleven patients (28.2%) had antecedents of previous surgery in the same location, 5 (12.8%) had previously received radiotherapy and chemotherapy, and 11 (28.2%) were smokers. Twenty-four patients (60%) underwent surgery for high-grade glioma, 8 (20%) for low-grade gliomas, 6 (15%) for metastasis and 2 (5%) for meningioma. Throughout the study and up to 90 days after surgery, none of the patients presented an ADR. Only 2 patients (5%) presented with a surgery complications derived from ventricular opening (one patient with a percutaneous CSF leakage and one patients with external hydrocephalus). Both patients resolved with a ventriculoperitoneal shunt. Conclusions: TachoSil® is a dural sealant that can be used safely and effectively intraparenchymally in patients whose surgery involves a ventricular opening. Only 5% of treated patients presented complications arising from CSF hydrodynamics. No patients had pseudomeningocele, infections or complications related to the use of this sealant. To confirm these positive results, randomized and comparative clinical trials assessing the efficacy of TachoSil® in patients after cranial surgery with an OVS are essential. Trial registration number and date of registration: This study was registered in the Clinical Trials.gov (NCT05717335). Date May 1st, 2022. [ABSTRACT FROM AUTHOR]

Background: Enhanced Recovery After Surgery (ERAS) has become increasingly popular in the post-operative management of abdominal surgery. Published data suggest that patients on ERAS protocols have fewer minor and major complications, and highlight a reduction in medical morbidity (such as urinary and respiratory infections). Limited data is available on surgical complications. The aim of the study was to evaluate the impact of the ERAS protocol on post-operative complications and length of hospital stay. Furthermore, we aimed to determine the impact of this protocol on cost-effectiveness. Material and methods: From January 2016 to December 2022, 532 colectomies for colorectal cancer (CRC) were performed. A prospective observational study was conducted in a tertiary hospital on the cohort of patients, aged 18 years and older, operated on for non-urgent colorectal cancer. The impact on post-operative complications, hospital stay and economic impact was analysed in two groups: patients managed under ERAS and non-ERAS protocol. A propensity score-matching analysis was performed between the two groups. Results: After propensity score matching 1:1, each cohort included 71 patients, and clinicopathological characteristics were well balanced in terms of tumour type, surgical technique and surgical approach. ERAS patients experienced fewer infectious complications and a shorter postoperative stay (p < 0.001). In particular, they had an 8.5% reduction in anastomotic dehiscence (p = 0.012) and surgical wound infections (p = 0.029). After analysis of medical complications, no statistically significant differences were identified in urinary tract infections, pneumonia, gastrointestinal bleeding or sepsis. ERAS protocol was more efficient and cost-effective than the control group, with an overall savings of 37,673.44€. Conclusions: The implementation of an enhanced recovery protocol for elective colorectal surgery in a tertiary hospital was cost-effective and associated with a reduction in post-operative complications, especially infectious complications.

Uncertainties regarding traditional osteological methods in biological sex estimation can often be overcome with genomic and proteomic analyses. The combination of the three methodologies has been used for a better understanding of the gender-related funerary rituals at the Iberian megalithic cemetery of Panoría. As a result, 44 individuals have been sexed including, for the first time, non-adults. Contrary to the male bias found in many Iberian and European megalithic monuments, the Panoría population shows a clear sex ratio imbalance in favour of females, with twice as many females as males. Furthermore, this imbalance is found regardless of the criterion considered: sex ratio by tomb, chronological period, method of sex estimation, or age group. Biological relatedness was considered as possible sociocultural explanations for this female-related bias. However, the current results obtained for Panoría are indicative of a female-centred social structure potentially influencing rites and cultural traditions. [ABSTRACT FROM AUTHOR]

[18F]Flortaucipir is an FDA-approved tau-PET tracer that is increasingly utilized in clinical settings for the diagnosis of Alzheimer's disease. Still, a large-scale comparison of the in vivo PET uptake to quantitative post-mortem tau pathology and to other co-pathologies is lacking. Here, we examined the correlation between in vivo [18F]flortaucipir PET uptake and quantitative post-mortem tau pathology in corresponding brain regions from the AVID A16 end-of-life study (n = 63). All participants underwent [18F]flortaucipir PET scans prior to death, followed by a detailed post-mortem neuropathological examination using AT8 (tau) immunohistochemistry. Correlations between [18F]flortaucipir standardized uptake value ratios (SUVRs) and AT8 immunohistochemistry were assessed across 18 regions-of-interest (ROIs). To assess [18F]flortaucipir specificity and level of detection for tau pathology, correlations between [18F]flortaucipir SUVR and neuritic plaque score and TDP-43 stage were also computed and retention was further assessed in individuals with possible primary age-related tauopathy (PART), defined as Thal phase ≤ 2 and Braak stage I–IV. We found modest-to-strong correlations between in vivo [18F]flortaucipir SUVR and post-mortem tau pathology density in corresponding brain regions in all neocortical regions analyzed (rho-range = 0.61–0.79, p < 0.0001 for all). The detection threshold of [18F]flortaucipir PET was determined to be 0.85% of surface area affected by tau pathology in a temporal meta-ROI, and 0.15% in a larger cortical meta-ROI. No significant associations were found between [18F]flortaucipir SUVRs and post-mortem tau pathology in individuals with possible PART. Further, there was no correlation observed between [18F]flortaucipir and level of amyloid-β neuritic plaque load (rho-range = – 0.16–0.12; p = 0.48–0.61) or TDP-43 stage (rho-range = – 0.10 to – 0.30; p = 0.18–0.65). In conclusion, our in vivo vs post-mortem study shows that the in vivo [18F]flortaucipir PET signal primarily reflects tau pathology, also at relatively low densities of tau proteinopathy, and does not bind substantially to tau neurites in neuritic plaques or in individuals with PART.

The 2022 and 2023 western Mediterranean summer temperatures exceeded millennial natural variability, reaching unprecedented anomalies of +3.6 °C and +2.9 °C respectively. We show that anthropogenic climate change may turn extreme heatwaves from a rarity of 1 in 10,000 years into events occurring every 4–75 years, depending on future scenarios. This shift underscores the urgency of implementing adaptive strategies as extreme climate events manifest sooner and more intensely than expected. [ABSTRACT FROM AUTHOR]

Purpose: Maximal-safe resection has been shown to improve overall survival in elderly patients with glioblastoma in observational studies, however, the only clinical trial comparing resection versus biopsy in elderly patients with surgically-accessible glioblastoma showed no improvements in overall survival. A meta-analysis is needed to assess whether surgical resection of glioblastoma in older patients improves surgical outcomes when compared to biopsy alone. Methods: A search was conducted until October 9th, 2023, to identify published studies reporting the clinical outcomes of glioblastoma patients > 65 years undergoing resection or biopsy (PubMed, MEDLINE, EMBASE, and COCHRANE). Primary outcomes were overall survival (OS), progression-free survival (PFS), and complications. We analyzed mean difference (MD) and hazard ratio (HR) for survival outcomes. Postoperative complications were analyzed as a dichotomic categorical variable with risk ratio (RR). Results: From 784 articles, 20 cohort studies and 1 randomized controlled trial met our inclusion criteria, considering 20,523 patients for analysis. Patients undergoing surgical resection had an overall survival MD of 6.13 months (CI 95%=2.43–9.82, p = < 0.001) with a HR of 0.43 (95% CI = 0.35–0.52, p = < 0.00001). The progression-free survival MD was 2.34 months (95%CI = 0.79–3.89, p = 0.003) with a 0.50 h favoring resection (95%CI = 0.37–0.68, p = < 0.00001). The complication RR was higher in the resection group favoring biopsy (1.49, 95%CI = 1.06–2.10). Conclusions: Our meta-analysis suggests that upfront resection is associated with improved overall survival and progression-free survival in elderly patients with newly diagnosed glioblastoma over biopsy. However, postoperative complications are more common with resection. Future clinical trials are essential to provide more robust evaluation in this challenging patient population.

Semiconductor spin qubits represent a promising platform for future large-scale quantum computers owing to their excellent qubit performance, as well as the ability to leverage the mature semiconductor manufacturing industry for scaling up. Individual qubit control, however, commonly relies on spectral selectivity, where individual microwave signals of distinct frequencies are used to address each qubit. As quantum processors scale up, this approach will suffer from frequency crowding, control signal interference and unfeasible bandwidth requirements. Here, we propose a strategy based on arrays of degenerate spins coherently dressed by a global control field and individually addressed by local electrodes. We demonstrate simultaneous on-resonance driving of two degenerate qubits using a global field while retaining addressability for qubits with equal Larmor frequencies. Furthermore, we implement SWAP oscillations during on-resonance driving, constituting the demonstration of driven two-qubit gates. Significantly, our findings highlight how dressing can overcome the fragility of entangling gates between superposition states and increase their noise robustness. These results constitute a paradigm shift in qubit control in order to overcome frequency crowding in large-scale quantum computing. Global control of a qubits using a single microwave field is a promising strategy for scalable quantum computing. Here the authors demonstrate individual addressability vial local electrodes and two-qubit gates in an array of Si quantum dot spin qubits dressed by a global microwave field and driven on-resonance.

Cancer curing immune responses against heterogeneous solid cancers require that a coordinated immune activation is initiated in the antigen avid but immunosuppressive tumor microenvironment (TME). The plastic TME, and the poor systemic tolerability of immune activating drugs are, however, fundamental barriers to generating curative anticancer immune responses. Here, we introduce the CarboCell technology to overcome these barriers by forming an intratumoral sustained drug release depot that provides high payloads of immune stimulatory drugs selectively within the TME. The CarboCell thereby induces a hot spot for immune cell training and polarization and further drives and maintains the tumor-draining lymph nodes in an anticancer and immune activated state. Mechanistically, this transforms cancerous tissues, consequently generating systemic anticancer immunoreactivity. CarboCell can be injected through standard thin-needle technologies and has inherent imaging contrast which secure accurate intratumoral positioning. In particular, here we report the therapeutic performance for a dual-drug CarboCell providing sustained release of a Toll-like receptor 7/8 agonist and a transforming growth factor-β inhibitor in preclinical tumor models in female mice. Co-delivery of TLR7/8 agonists and TGF-β inhibitors (TGFβi) has the potential to overcome immunosuppression in the tumor microenvironment. Here the authors describe the application of the CarboCell technology for the sustained intratumoral release of a TLR7/8 agonist alone or in combination with a TGFβi, promoting anti-tumor immune responses in preclinical cancer models.

Fish age and growth data are crucial for understanding vital species' traits and their populations. Boarfish is a pelagic species widely distributed in the Northeast Atlantic that is one of the most discarded non-commercial species on the Portuguese coast. Due to its potential valorisation as a new fishery in the Northeast Atlantic, boarfish has become object of interest in several published studies. However, since no age standard protocol has been implemented for boarfish, studies have used a variety of different otolith preparation techniques to estimate age, leading to contradicting and discrepant results. This research aims to consolidate biological insights into boarfish age and growth, lay the foundation for a standardized ageing protocol and serve as a benchmark study for the Portuguese west coast before commercial exploitation. Through the comparison of two otolith ageing methodologies, this study recommends using whole otoliths as the best method, revealing a maximum age of 15 years. The growth pattern estimated, indicated a biphasic growth pattern, with a faster initial growth rate that slows down at 2.4 years, the moment of change, when energy is allocated for sexual maturation. This finding was corroborated by a maturity ogive and analysis of fish size and otolith length relationship. [ABSTRACT FROM AUTHOR]

The objective of the article is to analyse the degree of persistence of overeducation in the initial stages of the professional career of young workers and the relationship between both the incidence and the persistence of overeducation and the business cycle. We use longitudinal data from administrative records (the 'Continuous Sample of Working Life') on the work trajectories of young Spaniards (16–35 years old) who enter the labour market for the first time at various moments in time (2005, 2009 or 2014) and estimate univariate and recursive bivariate probit models. The main findings are that nearly one third of entrants are overeducated in their first job, that their permanence in overeducation five years later is high (above 50%) and that the persistence of overeducation of young entrants is countercyclical.

The respiratory system is equipped with several defence mechanisms to protect the body from microorganisms and airborne pathogens. There are situations where the respiratory system can be overwhelmed or compromised and infection happens, especially in individuals with weakened immune systems. Airborne pathogens are a serious risk for human and animal health, as exemplified by the challenges faced during the COVID-19 pandemic. The list includes viruses of varying severity such as Influenza virus, SARS-CoV-2, measles virus, Varicella-Zoster Virus, or Respiratory syncytial virus among others. Smaller particles can remain suspended in the air for longer periods and may reach the lower respiratory tract, including the alveoli in the lungs. The real-time detection of these pathogens in the air presents a significant challenge. The aerosols, especially those carrying viruses, are so small that they often elude conventional air samplers, making it difficult both to detect their presence and to remove them effectively from the air. This work introduces a recent technique designed for rapid aerosol sampling, with a particular emphasis on virus sampling. The system underwent calibration using artificial ɸ29 virus aerosols and was subsequently tested with naturally emitted aerosols of SARS-CoV-2. A series of tests were conducted in diverse settings, including hospitals, farms, offices, and railway cars. The equipment is also capable of swiftly removing bioaerosols from the air, thereby facilitating effective decontamination. The relevance of this technology lies in its capability for swift detection and elimination of viruses and other kinds of aerosols from air, facilitating prompt decision-making during high-risk events.

Summary: Background: Seminal vesicle metastasis from colon adenocarcinoma is very rare, with only two case reports in the literature. Also, positron emission tomography/computed tomography (PET/CT) imaging in the diagnosis of seminal vesicle tumors seems to have a promising role in its detection, but there have been few reports about its use, in part due to the rarity of the disease. Case presentation: We report the case of a 64-year-old male patient with colon adenocarcinoma who at 6 years after the diagnosis presented with metastasis to the seminal vesicles, which responded remarkably to chemotherapy, but 2 years later had a relapse at the seminal vesicles. Imaging with PET/CT was helpful for the diagnosis of this case. Conclusion: Our case is unique, as there are no previous reports in the literature on the relapse of metastatic colon adenocarcinoma in the seminal vesicles. Imaging with PET/CT showed compromise of the seminal vesicles in our case; hence, this imaging technique seems to have a promising role in detecting metastatic seminal vesicle tumors.
