Environmental assessment of steroid endocrine disruptors in stranded cetaceans: A methodological approach to detection and analysis
No full textExploring the presence of endocrine disrupting compounds in marine organisms, particularly cetaceans, is crucial to evaluate contamination within the ocean’s food web and the detection of synthetic hormones in cetaceans is a strong indication of anthropogenic pollution in marine ecosystems. Due to their characteristics, blubber samples are a key component in assessing the analysis of cetaceans, but this type of sample require precise and sensitive analytical methods. Despite some methodologies have been developed for the analysis of natural steroid hormones in cetacean blubber, a significant gap persists in the comprehensive analysis of synthetic steroids within these samples. In this work, a QuEChERS (Quick, Easy, Cheap, Effective, Rugged, and Safe) extraction combined with UHPLC-MS/MS (ultra-high-performance liquid chromatography with tandem mass spectrometry) analysis was performed to determine six synthetic steroid hormones (nandrolone, prednisolone, prednisone, megestrol acetate, norethisterone, and norgestrel) in 11 stranded cetacean blubber samples. Despite the complex nature of blubber samples, the developed methodology showed promising results, with recoveries ranging from 70 % to 120 % for most target compounds at low concentration levels (150 ng⋅g 1). The method demonstrated high precision with relative standard deviations under 20 % in both intra- and inter-day experiments. Regarding the matrix effect, ion suppressions of about 50 % were also calculated for those samples spiked at concentration levels of 150 ng⋅g 1, nevertheless, all compounds were still able to be detected, in most cases below quantification limits. Notably, one sample presented a quantified concentration of megestrol acetate, a steroid hormone used in contraceptives and cancer treatments, at 26.98 ± 2.62 ng⋅g 1. The results affirm the methodology’s effectiveness for analyzing synthetic steroid hormone levels in cetacean blubber, providing a valuable tool for assessing environmental concentrations of these anthropogenic endocrine disruptors and their impact on cetacean welfare and conservation.90,8644,2Q1Q1SCIE11,
Genetic parameters of resistance to acute hepatopancreatic necrosis disease (AHPND) caused by<i> Vibrio</i><i> parahaemolyticus</i> and their genetic correlations with growth traits in an Ecuadorian<i> Penaeus</i><i> vannamei</i> population
No full textInfections with strains of Vibrio parahaemolyticus causing acute hepatopancreatic necrosis disease (VPAHPND) in Penaeus vannamei have not yet caused high levels of mortality in Ecuador like those reported in Asia; however, target animals resistant to VPAHPND are a goal for industrial farmers. The implementation of breeding programs to produce fast-growing and disease-resistant shrimp would be a key to addressing the expected situation. The main objective of this study was to estimate heritabilities and genetic correlations for VPAHPND resistance and growth traits in an Ecuadorian population cultured under industrial conditions. A total of 3345 animals from 155 sibling families of the PMG-BIOGEMAR (c) genetic breeding program were individually tagged, measured for initial length and weight (only for Test-1), and tested for VPAHPND in two trials: Test-1 at a concentration of 2 x 10(5) CFU/ml and infection by immersion and Test-2 at a concentration of 2 x 10(8) CFU/g and by oral infection. After 72 h, all shrimp were analysed for final weight and length, survival, and infection levels by Ct values (qPCR) of the pirA and pirB genes. Genetic parameters of growth and resistance traits were obtained using two statistical models: Linear and Threshold models. Heritabilities were medium (0.16-0.31) for growth and low (0.55) with both methodologies in Test-1 and low-medium and positive in Test-2 using Threshold model. The results suggest that genetic selection for growth in P. vannamei has a positive effect on resistance to AHPND. Furthermore, the genetic selection for growth over time in this Ecuadorian population may have induced possible resistance or tolerance to the disease.101,0593,9Q1Q1SCI
New distributional data and biometrics of some moray eel species (Muraenidae) in the Canary Islands and Western Sahara (east-central Atlantic)
No full textOver the last five centuries, moray eels (Muraenidae) have been subject to artisanal fishing in the waters of the Canary Islands and Western Sahara by Canarian fishermen, gaining culinary interest in the Canary Islands. This study updates the geographical distribution of some Muraenidae species in this region (27-23ºN), including cases of latitudinal and longitudinal migration. In the Canary archipelago, the natural expansion of Gymnothorax vicinus from El Hierro (2008) – the westernmost island with the warmest coastal waters – to the central islands is now confirmed. This species, potentially native to the region, has been observed in both the northern (more temperate) and southern (warmer) sectors of the archipelago, likely due to its broad habitat use and its aggressiveness. The presence of Gymnothorax miliaris – typically restricted to the western islands – at the easternmost end of the archipelago (Fuerteventura) is now documented. Muraena melanotis, first reported in Tenerife in 2018, has now expanded to El Hierro, as evidenced by the capture of a mature female. Current data suggest that this thermophilic species may have established a small population in the warmer western sectors of the archipelago. Additionally, unpublished biometric data on Canarian samples of G. miliaris and G. polygonius are provided. In Western Sahara, the first record of the amphi-Atlantic species Gymnothorax polygonius on the African continental coast is now documented. The presence of Gymnothorax afer and Muraena robusta at 23º32’N, the new northern distribution limit for both species, is now confirmed.0,2370,5Q3Q4SCIE11,
Living on the Edge: The Precariat Amid the Rental Crisis in the Metropolitan Area of Las Palmas de Gran Canaria (Spain)
No full textThis study examines access to rental housing in the metropolitan area of Las Palmas de Gran Canaria, linking it to socio-economic inequalities and the increasing precarization. In recent years, housing affordability has worsened due to rising rents, stagnant wages, and speculative dynamics—particularly those linked to tourism and platform-based economies. Drawing on official data from the State Reference System for Rental Housing Prices (SERPAVI) and income statistics at the census tract level, this research quantifies housing affordability and spatial disparities through indicators such as economic effort rates. The analysis identifies patterns of exclusion and urban fragmentation, showing that large sectors of the population—especially those earning the minimum age—face severe barriers to accessing adequate housing. The findings highlight the insufficiency of current public policies and propose the expansion of social rental housing and stricter rental market regulation as necessary steps to ensure fairer urban conditions.250,587Q17,
Technological Innovations in Risk Communication: The case of Gran Canaria (Canary Islands, Spain) in the implementation of the ES-Alert system in emergency management
No full textThe ES-Alert system, implemented in the Canary Islands, constitutes a significant innovation in risk communication and emergency management. This study aims to assess its deployment on the island of Gran Canaria following the simulation exercise conducted on September 26, 2024, by the Emergency and Security Coordination Center 112 of the Government of the Canary Islands. Additionally, the study evaluates aspects related to risk perception among the population. The effectiveness of the system was analysed based on mass messaging sent by the authorities to the entire population of Gran Canaria. A non-probabilistic convenience sampling approach was employed, targeting students, faculty, and administrative staff at the University of Las Palmas de Gran Canaria. The survey examined key aspects such as message clarity, perceived usefulness, and impact on decision-making. Findings indicate a high level of acceptance of the system, with 87% of participants considering it useful in real emergency situations. However, 31% identified areas for improvement in message clarity, and 42% reported that their response capability would depend on the type of emergency. These results underscore the importance of precisely defining emergency messages while effectively capturing public attention to elicit appropriate responses. Furthermore, the findings highlight the necessity of enhancing public training and awareness to facilitate immediate and informed decision-making in different emergency scenarios. The study also emphasizes the crucial role of communication technologies and geographic information systems in modernizing emergency management. Overall, ES-Alert has been found to optimize early warning dissemination and significantly improve decision-making processes, establishing itself as a key tool for enhancing community resilience in island contexts.

Effect of radiographic malpositioning on patellar height measurements: implications for diagnosis and surgical planning. A retrospective observational study
No full textPurpose Patella alta stands as a significant predisposing factor for patellofemoral instability. Patellar heights indexes (PHI)
require precise lateral knee radiographic projections for accurate computation. However, within clinical contexts, a notable
proportion of radiographic images are taken with certain degrees of excessive rotation and/or tilting. The primary aim of this
investigation was to assess the impact of suboptimal radiographic positioning on the determination of patellar height, utilizing
the Blackburne-Peel (BP), Caton-Deschamps (CD) and Insall-Salvati (IS) indexes. Secondarily, it was evaluated whether any
index is more sensible to suboptimal radiographic positioning, and how inter and intra observer reproducibility are affected.
Methods Thirty-three patients with strictly lateral radiographs and another one demonstrating a noticeable degree of tilt and/
or rotation were included in the study. Four orthopaedic surgeons specialized in knee surgery and four Orthopaedics residents
conducted measurements on each radiograph in a randomized sequence at two different time points. A linear mixed-effects
model was applied, with the quality of the radiograph (adequate projection vs malrotation, tilt, or both), observer expertise
(consultant or resident), and observation time regarded as fixed effects, while consultant and patient were treated as random
effects.
Results Statistically significant differences were obtained between strict lateral and tilted radiographs in the BPI, with an
overestimation of up to 0.0937; between strict lateral and malrotated radiographs in the ISI, showing an overestimation
of up to 0.0696 and between tilted and/or rotated radiographs in the CDI, with overestimation reaching up to 0.0813. No
significant differences were observed between resident and consultant observers in any of the indexes. Good inter-observer
consistency was achieved.
Conclusion This study showed statistically significant differences in the determination of the three PHIs. Although these
differences were small, they may predispose to diagnostic errors and inaccurate surgical planning in cases requiring surgical
correction. Future studies quantifying the degrees of malrotation and/or inclination may further clarify these findings.70,73Q18,
Gender differences in the form and use of boosters and downtoners in 18th and 19th century medical instructional texts
No full textMedical writing in Late Modern English (1700–1899) reflects evolving rhetorical strategies for
establishing authority, particularly through boosters (e.g., certainly, undoubtedly) and
downtoners (e.g., perhaps, somewhat). While Hyland’s (2005) model of stance and metadiscourse
has been extensively applied to modern academic writing, its role in historical medical
discourse—especially from a gendered perspective—remains underexplored. This study
examines the use of boosters and downtoners in the 18th- and 19th-century sections of the
Corpus of Women’s Instructive Texts in English (CoWITE), comparing them to a reference corpus
of male-authored medical texts.
Through a corpus-based analysis of stance markers, this study reveals distinct gendered
rhetorical strategies. Female writers tend to use downtoners more frequently, softening
assertions and introducing epistemic caution ('it may be beneficial to consider...'), a strategy in
line with broader patterns of politeness and reader engagement (Hyland, 1998). In contrast, maleauthored texts show a preference for boosters, reinforcing certainty and medical authority ('it is
unquestionably the best method...'), positioning the writer as a more authoritative voice (Hyland,
2005). These results suggest that women writers managed credibility differently, often adopting
mitigative strategies to balance expertise with social expectations.
This study seeks to contribute to historical research on gendered persuasion in medical technical
discourse, highlighting how linguistic choices reflected epistemic authority, professional
boundaries, and engagement with readers and peers. Findings offer new insights into the
historical evolution of medical communication, informing both diachronic studies of
metadiscourse and gendered professional rhetoric
