Osteoarthritis (OA) is characterized mainly by articular cartilage loss, subchondral osteosclerosis, and chronic inflammation and involves multiple types of cellular dysfunction and tissue lesions. The rapid development of nanotechnology and materials science has contributed to the application of biomimetic nanomaterials in the biomedical field. By optimizing the composition, hardness, porosity, and drug loading of biomimetic nanomaterials, their unique physicochemical properties drive potential applications in bone repair. This article reviews the present understanding of the physiopathological mechanism and clinical treatment drawbacks of OA and summarizes various types of biomimetic nanomaterials for OA that target lesion sites, such as cartilage, subchondral bone, and synovium, through simulation of the physiological structure and microenvironment. Eventually, the challenges and prospects for the clinical translation of biomimetic nanomaterials are further discussed, with the goal of accessing an effective approach for OA treatment.

The rapid growth of shrimp farming, particularly of Penaeus vannamei, accounts for about 80% of the global production of farmed shrimp and involves the cultivation of approximately 383 to 977 billion individuals annually, which highlights the urgent need to address the ethical and technical implications of raising potentially sentient beings. This study builds on the state-of-the-art assessment of sentience, consciousness, stress, distress, nociception, pain perception, and welfare to adapt the General Welfare Index (GWI) for farmed shrimp. The GWI is a quantitative index developed by our research group to measure the degree of welfare in aquaculture, and it has been previously applied to grass carp and tilapia. Using the PRISMA methodology and the creation of a hypothetical shrimp farm, the GWI, with 31 specific and measurable indicators across various welfare domains, is adapted to P. vannamei, offering a comprehensive assessment framework. The inclusion of quantitative welfare indicators promises to improve living conditions in alignment with legislation adopted on decapods' sentience and contemporary scientific advances.

The use of fish meal/oil in carnivorous fish feeds remains a concern for the environmental sustainability of aquaculture. In this study, we investigated the impact of an innovative diet designed to be cost‐effective and environmentally sustainable (i.e., 60% replacement of fish meal by a blend of plant, yeast [Saccharomyces cerevisiae], and krill meal feed ingredients) on the growth, health, and welfare of gilthead seabream (Sparus aurata). Over a 135‐day experiment, fish were fed either the innovative or a commercial diet (control), and various parameters were evaluated, namely growth performance, levels of physiological blood parameters related to stress, immunity, health, and welfare, as well as swimming activity, serving as a proxy for energy expenditure. Results revealed that the innovative diet enhanced growth compared to fish fed the control diet. Hematological and biochemical indicators did not highlight any impaired welfare condition in fish fed innovative diet while higher levels of Immunoglobulin M were measured in plasma of fish fed innovative diet, potentially suggesting enhancement of humoral immunity. However, accelerometer tags data revealed that fish fed the innovative diet exhibited higher overall swimming activity, suggesting higher energy expenditure, which was consistent with greater prealbumin levels measured in the plasma. In conclusion, the higher energy metabolism in fish fed the innovative diet might be compensated by the diet's content, which may boost humoral immunity and hence help the fish develop a better adaptation to rearing environment, including its viral and bacterial load, ensuring overall better growth. Longer term investigations, including measurements of additional parameters, are required to validate these promising preliminary outcomes. [ABSTRACT FROM AUTHOR]

Background: There is little evidence that single-session debriefing is effective in reducing adverse mental health outcomes after trauma. Few trials have included long-term follow-up, but two also suggest possible negative effects of debriefing. We aimed to assess longer-term maternal health outcomes in a trial of midwife-led debriefing following an operative birth, given that findings at six months could not rule out a possible adverse effect of debriefing., Methods: Four to six years after participating in a midwife-led trial of debriefing following an operative birth, 1039/1041 women were mailed a questionnaire containing the Edinburgh Postnatal Depression Scale (EPDS) and the SF-36 health status measure., Results: Responses were obtained from 534 women (51.4%). Responders from the two trial groups remained comparable 4-6 years postpartum. No significant differences on maternal health outcomes were found between the trial groups., Conclusion: In the longer term, maternal health status was neither positively nor adversely affected by the experience of debriefing, despite a hint of adverse effects at six months postpartum. Short debriefing interventions have not proven effective in improving mental health outcomes for women following childbirth.

Kaposi's sarcoma-associated herpesvirus/human herpesvirus type-8 (KSHV/HHV-8) is associated with primary effusion lymphomas (PEL), a rare form of B-cell lymphoma. PEL cell lines infected with HHV-8, but negative for Epstein-Barr virus (EBV), were analyzed for their tumorigenic potential in a small animal model system. Inoculation of PEL cell lines into non-obese diabetic/severe combined immunodeficient (NOD/SCID) mice results in efficient engraftment and tumorigenesis in vivo. PEL-engrafted NOD/SCID (PEL/SCID) mice displayed malignant ascites development with notable abdominal distension, consistent with the clinical manifestations of PEL in humans. Azidothymidine (AZT, zidovudine) and interferon-alpha (IFN-alpha) induce apoptosis in HHV-8+/EBV- PEL cells in culture, by induction of a tumor necrosis factor-related apoptosis inducing ligand (TRAIL) mediated suicide program and has been proposed as a therapy for herpesvirus-associated lymphomas. Daily injection of AZT and IFN-alpha significantly increased mean survival time (MST) of PEL/SCID mice suggesting that induction of apoptosis in PEL cells in vivo may be exploited as an effective relatively non-toxic therapy targeting HHV-8 infected PEL. These data demonstrate that the PEL/SCID mouse is an important preclinical model to characterize efficacy and anti-tumor mechanisms of new therapeutic targets in vivo and will be useful in the design and testing of agents in viral lymphoproliferative diseases.

DNA double helices containing metal-mediated DNA (mmDNA) base pairs are constructed from Ag + and Hg 2+ ions between pyrimidine:pyrimidine pairs with the promise of nanoelectronics. Rational design of mmDNA nanomaterials is impractical without a complete lexical and structural description. Here, the programmability of structural DNA nanotechnology toward its founding mission of self-assembling a diffraction platform for biomolecular structure determination is explored. The tensegrity triangle is employed to build a comprehensive structural library of mmDNA pairs via X-ray diffraction and generalized design rules for mmDNA construction are elucidated. Two binding modes are uncovered: N3-dominant, centrosymmetric pairs and major groove binders driven by 5-position ring modifications. Energy gap calculations show additional levels in the lowest unoccupied molecular orbitals (LUMO) of mmDNA structures, rendering them attractive molecular electronic candidates., (© 2023 Wiley-VCH GmbH.)

Fish domestication progresses through five levels: from the initial acclimatization to captivity (Level 1), to the life cycle completion in captivity (Level 4), and even to the implementation of selective breeding programs (Level 5). Domestication leads to phenotypic changes over generations, sometimes from the very first generation. Behavioral traits are among the first to change. However, in fish, potential behavioral changes during early domestication have been little studied. Therefore, we studied potential behavioral changes among early and advanced levels of domestication in a model species, the zebrafish (Danio rerio), using a mirror test experiment, commonly used to assess traits involved in activity, aggressiveness, and stress in this species. We compared these traits between wild zebrafish in captivity (F0; Level 1), the first generation of their captive-born offspring (F1; Level 4), and three laboratory strains (AB, TU, and WIK; Level 5). Each fish was individually filmed and tracked using an automated procedure for 5 min. Nine behavioral traits and one activity-related trait were characterized for each individual based on the movements and positioning of the fish. We applied a principal component analysis (PCA) and tested the significance of potential differences between groups using an analysis of similarities (ANOSIM). We applied an indicator value analysis (IndVal) to determine which traits were most expressed by each group. We detected differences between groups and across domestication levels. More specifically, we highlighted differentiations between different levels of domestication (e.g. between F1, AB, TU, and WIK) as early as the beginning of the domestication process (i.e. F0 vs. F1), but also within the same level of domestication (i.e. AB vs. TU). Based on PCA and IndVal, (i) F0 and F1 tended to show stronger expression of stress-related traits than the other groups, (ii) F0 was more active than others, and (iii) TU was more aggressive than AB. Our results confirmed that domestication can change fish behavior, even in the first generation born in captivity, although these modifications remain limited. In contrast, we did not observe any general trends correlated with domestication levels, given that AB and TU diverged in their aggressiveness levels, and WIK differed only from F1. This result needs to be generalized to other species but also considered for domestication for aquaculture. If future studies confirm that the changes observed at the beginning of the domestication process remain limited and that there is no consistent evolutionary trend across generations in fish, this would highlight the crucial importance of selecting the right species from the outset of domestication. It would also emphasize the need to design selective breeding programs that shape fish stocks with the most desirable characteristics. To our knowledge, this study is one of the few to examine the behavior of wild zebrafish alongside laboratory strains, offering a unique insight into the early stages of domestication.

Public schools are a major provider of mental health services for children in the US. Mental and behavioral health services range from universal programming to individualized clinical supports to address student needs. These services in schools are delivered by various professionals including non-teaching and teaching school personnel, school-employed clinicians, and/or contracted community mental health partners. Provision of mental health services requires complex coordination of providers across disciplines, although few professionals have training in multidisciplinary collaboration strategies. Attention to team processes, such as delineating team members' roles, improving communication, and identifying collaboration strategies, may impact the effectiveness of evidence-based mental health service provision in real world settings. One intervention, Team Strategies and Tools to Enhance Performance and Patient Safety (TeamSTEPPS), has been used in healthcare with positive outcomes and has been adapted to educational settings. The current paper describes the community-partnered subsequent adaptation of TeamSTEPPS for schools. Needs assessment interviews identified challenges, successes, and goals for student mental health. Overarching themes extracted from interviews include limited resources at multiple levels (e.g., financial support, time, and personnel), communication challenges, and poor role clarity. A community advisory board provided guidance during the adaptation and implementation planning process. Adaptations to the intervention included tailoring the intervention to the school context and the development of flexible training plans. In addition, individualized implementation plans were developed with each school partner to mitigate foreseeable barriers to rolling-out TeamSTEPPS. Our team is currently piloting the adapted TeamSTEPPS intervention and implementation strategies in partnership with three school districts. [ABSTRACT FROM AUTHOR]

Aim(s): Teamwork among healthcare professionals is a key aspect of patient safety that influences the prevalence of missed nursing care. The association between teamwork and missed care in acute care hospitals is now well established in the literature. Therefore, this review aimed to synthesise the existing empirical evidence on the association between teamwork and missed care in the acute care setting. Design: A mixed‐method systematic review study. Methods: The search was carried out in February 2023 in four scientific databases, PubMed, ProQuest, Web of Science and Scopus based on their institutional availability. The search produced 1542 studies. The method of thematic analysis was used in data synthesis. Results: A total of 18 studies were selected that revealed the relationship between teamwork and missed care. The teamwork score was weak to moderate but significantly associated with the overall score of missed care and was found to be a statistically significant predictor of missed care in an acute care setting. Additionally, teamwork represented an important reason for missed care, primarily in the context of poor communication, lack of trust and cooperation in the nursing team and lack of leadership. Conclusion: The review findings contribute to a deeper understanding of the intricate dynamics between teamwork and missed care and provide valuable information to healthcare professionals and institutions looking to optimise teamwork and mitigate instances of missed care in the acute care setting. Implications for the Profession and/or Patient Care: Recognising how teamwork influences the occurrence of missed care, healthcare organisations can strategically implement targeted interventions to enhance collaboration, address communication gaps, foster trust, and provide effective leadership. Impact: This review suggests that improving teamwork seems to be one of the most important strategies focused on mitigating missed care in acute care settings. Reporting Method: The reporting of this review followed the PRISMA 2020 checklist. Patient or Public Contribution: No patient or public contribution. [ABSTRACT FROM AUTHOR]

Temperature modifies the reproductive success of fish, yet, in many species, we lack the information on its role in the early development. In this study, the effect of temperature on the relation between maternal traits (length, age, somatic condition, and muscle lipid and ovarian thyroid hormone concentrations), egg quality (fertilization success, development rate, mortality, and hatching success), and offspring traits (size-at-hatch, yolk sac size, and proportion of malformations) were studied in Baltic herring (Clupea harengus membras) in the northern Baltic Sea. The experiments were conducted at an ambient temperature of 7 °C and at an elevated temperature of 14 °C using 5 to 10 females and 3 replicates per female. The results indicate that elevated temperature may result in a faster developmental rate, a lower early-stage mortality and hatching success, smaller size-at-hatch, a larger yolk sac size, and a higher amount of larval malformations when compared to an ambient temperature. The egg and offspring traits were also associated with the maternal traits, indicating especially that thyroid hormones play a mediating role in the physiological processes. [ABSTRACT FROM AUTHOR]

Student-athlete well-being is a key objective for individuals working with or for university athletic departments. This paper will describe how a university athletic department used a team approach to enhancing student-athlete health and well-being. The Interprofessional Education Collaborative (IPEC) Core Competencies of (1) Values and Ethics; (2) Roles and Responsibilities; (3) Communication; and (4) Teams and Teamwork provide a guiding framework for interprofessional collaboration. (IPC; Interprofessional Education Collaborative, 2023). However, significant barriers exist in implementing IPC in university athletic departments and little research exists on how to overcome these barriers in university athletic departments to enhance student-athlete wellness. To address this gap, this paper will first provide a review of the literature on athlete well-being, followed by an applied section that describes the experience of an interprofessional wellness team (IWT) consisting of a clinical sports psychology doctoral student, a licensed mental health professional, an athletic trainer, and a sports dietitian. A case vignette is used to demonstrate how IPEC core competencies are operationalized by the team to address athlete health and well-being through IPC. Recommendations on the further implementation of IPC centered around student-athlete well-being will be provided. [ABSTRACT FROM AUTHOR]

Background: An intravesical gas explosion is a rare complication of transurethral resection of the prostate (TURP). It was first reported in English literature in 1926, and up to 2022 were only forty-one cases. Injury from an intravesical gas explosion, in the most severe cases appearing as extraperitoneal or intraperitoneal bladder rupture needed emergent repair surgery. Case presentation: We present a case of a 75-year-old man who suffered an intravesical gas explosion during TURP. The patient underwent an emergent exploratory laparotomy for bladder repair and was transferred to the intensive care unit for further observation and treatment. Under the medical team's care for up to sixty days, the patient recovered smoothly without clinical sequelae. Conclusions: This case report presents an example of a rare complication of intravesical gas explosion during TURP, utilizing root cause analysis (RCA) to comprehend causal relationships and team strategies and tools to improve performance and patient safety (TeamSTEPPS) method delivers four teamwork skills that can be utilized during surgery and five recommendations to avoid gas explosions during TURP to prevent the recurrence of medical errors. In modern healthcare systems, promoting patient safety is crucial. Once complications appear, RCA and TeamSTEPPS are helpful means to support the healthcare team reflect and improve as a team.

Interprofessional collaboration (IPC) is essential for high-quality palliative care (PC) for persons with dementia. The aim of this scoping review was to identify IPC approaches in palliative dementia care and explore the elements constituting these approaches. We performed a search in PubMed, CINAHL, and PsychINFO using the Joanna Briggs Institute Reviewers' manual and PRISMA guidelines, and conducted content analysis of the included articles. In total, 28 articles were included, which described 16 IPC approaches in palliative dementia care. The content analysis revealed three overall elements of these approaches: 1) collaborative themes, 2) collaborative processes, and 3) resources facilitating collaboration. Frequently reported collaborative themes embraced pain management and providing care in the dying phase. These themes were addressed through intertwined collaborative processes including communication, coordination, assessing and monitoring, and reflecting and evaluating. To ensure optimal IPC in palliative dementia care, various resources were required, such as PC knowledge, skills to manage symptoms, skills to communicate with collaborators, and a facilitating environment. In conclusion, the identified IPC approaches in palliative dementia care involve diverse collaborating professionals who mainly manage symptoms, prepare for the dying phase and require material and immaterial resources to enable optimal IPC in palliative dementia care.

Interprofessional practice can look quite different depending on a number of dynamics. Interprofessional education interventions may or may not orient toward this range of practice possibilities. This literature review explores: (1) how interprofessional education interventions relate to different kinds of interprofessional practice and (2) the range of interprofessional practices assumed by interprofessional education interventions. Four databases were searched for articles published between 2011–2021 describing pre-licensure level interprofessional education interventions, resulting in a dataset of 110 articles. Our analysis involved (1) descriptive summaries of the articles, and (2) content analysis of the rationale and description of the intervention. Of the articles, 93% (102/110) of interprofessional education interventions were designed and/or evaluated using the concept of interprofessional education competencies. "Teamwork" was the most relied upon competency. Most articles were not explicit about the different kinds of interprofessional practices that these competencies might be oriented toward. Our study substantiates earlier claims that interprofessional education literature tends to focus on competencies and orient toward undifferentiated understandings of "teamwork." This analysis is particularly important as interprofessional teams are engaging in increasingly complex, fluid, and distributed forms of interprofessional practice that may not be captured in an undifferentiated approach to "teamwork."

The DNA tensegrity triangle is known to reliably self-assemble into a 3D rhombohedral crystalline lattice via sticky-end cohesion. Here, the library of accessible motifs is expanded through covalent extensions of intertriangle regions and sticky-end-coordinated linkages of adjacent triangles with double helical segments using both geometrically symmetric and asymmetric configurations. The molecular structures of 18 self-assembled architectures at resolutions of 3.32-9.32 Å are reported; the observed cell dimensions, cavity sizes, and cross-sectional areas agree with theoretical expectations. These data demonstrate that fine control over triclinic and rhombohedral crystal parameters and the customizability of more complex 3D DNA lattices are attainable via rational design. It is anticipated that augmented DNA architectures may be fine-tuned for the self-assembly of designer nanocages, guest-host complexes, and proscriptive 3D nanomaterials, as originally envisioned. Finally, designer asymmetric crystalline building blocks can be seen as a first step toward controlling and encoding information in three dimensions., (© 2022 Wiley-VCH GmbH.)

Background: Multiple sclerosis (MS) is a chronic neuroinflammatory and demyelinating condition that causes movement problems due to a probable failure to differentiate oligodendrocyte precursor cells into myelinating oligodendrocytes., Aims: This work aims to evaluate the effect of exosomes derived from human umbilical cord mesenchymal stem cells on functional recovery in an animal model of multiple sclerosis., Methods: The adult male C57BL/6J mice were randomly divided into three groups. The control mice were provided with a standard diet (CONT group). The chronically demyelinated (CPZ) group was fed a 0.2% cuprizone diet for 12 weeks. In the third group, mice received exosomes weekly for three weeks following chronic demyelination (Exo/CPZ group). The mice in the groups were tested weekly for mobility using a beam walking test (BWT), and their corpus callosum was studied histologically, immunohistochemically, and molecularly., Results: According to BWT results, hucMSC-Exos enhanced motor function in mice following cuprizone intoxication. Histological staining revealed a substantial increase in remyelination in the corpus callosum. Moreover, immunohistochemical tests revealed that hucMSC-Exos lowered the level of demyelination and improved glial response by lowering the number of microglia and astrocytes. In addition, hucMSC-Exos also upregulated the expression of genes associated with the oligodendrocyte lineage., Conclusions: hucMSC-Exos administration in the animal model of chronic MS leads to improved movement function, likely due to increased remyelination, modulation of inflammatory processes, and increased expression of genes related to the oligodendrocyte lineage. Therefore, using hucMSC-Exos seems to be a promising treatment strategy for demyelinating illnesses such as MS., Competing Interests: Declarations.

Demyelination is a frequent yet crippling neurological disease associated with multiple sclerosis (MS). The cuprizone (CZ) model, which causes demyelination through oxidative stress and neuroinflammation, is a popular tool used by researchers to examine this process. The polyphenol resveratrol (RESV) has become a promising neuroprotective agent in seeking for efficient therapies. In a rat model given CZ, we created and examined iron oxide nanoparticles (IONPs) loaded with RESV (IONP-RESV) to see how effective they were as a therapeutic agent against free RESV. According to molecular mechanisms, exposure to CZ resulted in a marked downregulation of myelin proteolipid protein (PLP) expression and an overexpression of the inflammatory markers tumor necrosis factor-α (TNF-α) and S100β, which are indicators of demyelination and neuroinflammation. It is remarkable that these CZ-induced alterations could be reversed by therapy with either RESV or IONP-RESV. Interestingly, IONP-RESV showed even stronger anti-inflammatory activity, as shown by a more noticeable downregulation of TNF-α and S100β expression. These results were confirmed by histopathological examination of the cerebral cortices. Our findings support the better neuroprotective benefits of RESV-loaded IONPs over free RESV in reducing demyelination and neuroinflammation brought on by CZ. Owing to their pro-remyelinating, anti-inflammatory, and antioxidant properties, RESV-loaded IONPs show promise as a neurotherapeutic intervention in the future for neurological diseases such as multiple sclerosis., Competing Interests: Declarations.

Nickel (Ni) as a waterborne metal pollutant is widespread and harms fish health. In this study, the effects of fortifying diets with 0.1% Melaleuca alternifolia (MO) and 0.1% Ocimum basilicum (BO) essential oils on behaviors, neurotransmitters, liver and kidney functions, biochemical indices, and tissue histological features were studied in Nile tilapia (Oreochromis niloticus) under Ni exposure conditions. A total of 240 fish (27.92 ± 0.22 g) were equally classified into six groups, each with four replicates of 10 fish. The control, MO, and BO groups were fed basal control, 0.1% MO, and 0.1% BO diets, respectively, and reared in Ni-free water. The Ni, Ni + MO, and Ni + BO groups were reared in Ni-medium at a concentration of 3.6 mg/L and fed the same feeding regime as the control, MO, and BO groups, respectively. Ni exposure induced behavioral alterations, including lowered foraging (coefficients of variation, CV = 2.73-14.29%), swimming (CV = 2.95-19.23%), mouth pushing (CV = 9.12-29.37%), spreading of the tail (CV = 3.13-17.32%), and approach (CV = 3.53-11.27%) patterns but increased surfacing (CV = 11.39-23.33%) and resting (CV = 7.14-25%) behaviors. Increased mortality (CV > 30%) and hepato-renal indicators were consequences of Ni exposure. The Ni exposure also depressed brain acetylcholine esterase (AChE) (CV = 0.54-1.10), blood total protein (CV = 3.23-21.87%), albumin (CV = 1.62-13.47%), and globulin (CV = 1.91-24.72%). Histopathological changes were observed in the brain, gills, liver, kidney, and muscle, with detectable Ni residues in the muscle of Nile tilapia. Dietary supplementation with 0.1% MO and/or 0.1% BO significantly improved behavior patterns, blood proteins, and AChE levels under Ni exposure conditions. Hepato-renal indicators and the histology of the studied organs were enhanced, and the residual Ni level was reduced by feeding on the tested diets. Based on the current results, it was concluded that essential oils (0.1% BO and/or 0.1% MO) diets could mitigate the harmful effects caused by Ni exposure in Nile tilapia, which might enhance their future application as effective feed additive candidates in aquaculture., Competing Interests: Declarations.

From the day we are born, the nervous system is subject to insult, disease and degeneration. Aberrant phosphorylation states in neurofilaments, the major intermediate filaments of the neuronal cytoskeleton, accompany and mediate many pathological processes in degenerative disease. Neuronal damage, degeneration and death can release these internal components to the extracellular space and eventually the cerebrospinal fluid and blood. Sophisticated assay techniques are increasingly able to detect their presence and phosphorylation states at very low levels, increasing their utility as biomarkers and providing insights and differential diagnosis for the earliest stages of disease. Although a variety of studies focus on single or small clusters of neurofilament phosphorylated epitopes, this review offers a wider perspective of the phosphorylation landscape of the neurofilament heavy subunit, a major intermediate filament component in both ageing and disease., (© 2024 International Society for Neurochemistry.)

Protein phosphorylation is one of the most common mechanisms regulating cellular signaling pathways, and many kinases and phosphatases are proven drug targets. Upon phosphorylation, protein functions can be further regulated by the distinct isomerase Pin1 through cis-trans isomerization. Numerous protein targets and many important roles have now been elucidated for Pin1. However, no tools are available to detect or target cis and trans conformation events in cells. The development of Pin1 inhibitors and stereo- and phospho-specific antibodies has revealed that cis and trans conformations have distinct and often opposing cellular functions. Aberrant conformational changes due to the dysregulation of Pin1 can drive pathogenesis but can be effectively targeted in age-related diseases, including cancers and neurodegenerative disorders. Here, we review advances in understanding the roles of Pin1 signaling in health and disease and highlight conformational regulation as a distinct signal transduction checkpoint in disease development and treatment.

Polyculture is a relevant practice for improving the sustainability of aquaculture, which raises interest in implementing it in a variety of production systems. However, polyculture is a complex approach that can result not only in complementarity among species but also competition among them and animal welfare issues. Potential polyculture benefits can be expected provided that compatibility and complementarity occur among the combined species. This places a premium on identifying the best species combinations for a given aquaculture system. Here, we developed a conceptual integrative workflow to standardise and plan the development of new fish polycultures. This workflow is designed to screen all possible combinations in a set of species based on three successive steps of assessment. Overall, these steps consider the compatibility and complementarity of co‐farmed species as well as stakeholder demands, sustainability and fish welfare. Step 1 consists of selecting the most promising compatible species combinations (i.e., 'prospective combinations') as a function of stakeholder opinion and expectations using databases and surveys. Step 2 validates the effectiveness of prospective combinations based on bioassays by considering species complementarity and animal welfare. Step 3 implements the best species combination(s) in aquaculture production, during which prototyping allows the sustainability of the resulting commercial production system to be studied. In conclusion, the workflow aims at being a valuable tool to innovate in aquaculture by exploiting the opportunities and the strengths of polyculture. [ABSTRACT FROM AUTHOR]

Urban site analysis includes tangible factors such as the physical site features and intangible factors as the sensory site features like odors affect the inhabited area in the site. Environmental and chemical studies have much greater attention and studies to the odor effects in urban areas than urban designers. This paper aims to provide a validated and applicable method for urban designers in odor measurement. The objective of this research is to present the various methods of measuring odors adopted in chemical and environmental studies to achieve an applicable odor measurement method in the urban design field. The odor measurement tools are usually dedicated to measuring odor concentration at the odor source or at the receptor location that are used in chemical and environmental studies. However, in urban design studies the odor measurement could be performed using a method called citizen science considering the FIDOL factor to evaluate the odor nuisance including odor frequency, intensity, duration, offensiveness, location, and hedonic tone. This research conducts a case study in Tripoli city and determines Tripoli landfill as a significant odor source that affects people in their inhabited areas. A questionnaire was distributed in the affected area by the odor source, and the respondents of the inhabitants ensured that the summer season is the most season that they can feel the odor in their places associated with the wind direction. The results ensure that the citizen science method in measuring odors is validated, applicable, and available for urban designers to detect and estimate the affected area by odor source.

In healthcare, effective communication and teamwork are pivotal in reducing medical errors. Integrating team training into health professions education is crucial. Accurate measurement of team performance during training requires reliable assessment tools. The TeamSTEPPS® Team Performance Observation Tool (TPOT), recently updated by the Agency for Healthcare Research and Quality, serves this purpose. However, it had not been translated and validated for use in Thailand. We aimed to translate and assess the psychometric properties of the Thai version of TPOT. Employing a back-translation process, TPOT was adapted to the Thai context. The resulting Thai TPOT instrument was administered to 518 healthcare professionals who had undergone TeamSTEPPS® training. Participants were asked to evaluate two prerecorded, 7-minute simulated team emergency scenarios using the Thai TPOT instrument. Results exhibited high internal consistency (Cronbach's alpha =.96) and inter-rater reliability (ICC =.98). Confirmatory factor analysis affirmed the construct validity of the Thai TPOT. These findings establish the Thai TPOT as useful for evaluating teamwork within healthcare teams. [ABSTRACT FROM AUTHOR]

Cocaine use disorder (CUD) is a chronic neuropsychiatric condition that results from enduring cellular and molecular adaptations. Among substance use disorders, CUD is notable for its rising prevalence and the lack of approved pharmacotherapies. The nucleus accumbens (NAc), a region that is integral to the brain's reward circuitry, plays a crucial role in the initiation and continuation of maladaptive behaviors that are intrinsic to CUD. Leveraging advancements in neuroproteomics, we undertook a proteomic analysis that spanned membrane, cytosolic, nuclear, and chromatin compartments of the NAc in a mouse model. The results unveiled immediate and sustained proteomic modifications after cocaine exposure and during prolonged withdrawal. We identified congruent protein regulatory patterns during initial cocaine exposure and reexposure after withdrawal, which contrasted with distinct patterns during withdrawal. Pronounced proteomic shifts within the membrane compartment indicated adaptive and long-lasting molecular responses prompted by cocaine withdrawal. In addition, we identified potential protein translocation events between soluble-nuclear and chromatin-bound compartments, thus providing insight into intracellular protein dynamics after cocaine exposure. Together, our findings illuminate the intricate proteomic landscape that is altered in the NAc by cocaine use and provide a dataset for future research toward potential therapeutics. Editor's summary: Cocaine use, addiction, and relapse are challenging to treat. Reward circuits in the brain activated by cocaine include the nucleus accumbens (NAc) in the CNS. Mews et al. performed subcellular proteomics of the NAc in mice to explore the spatiotemporal protein landscape during chronic cocaine use, withdrawal, and reuse. The findings implicated plasma membrane–associated proteins and intranuclear protein shuttling during withdrawal, providing insight into the intricate protein dynamics from which therapeutic strategies might be developed. —Leslie K.

The COVID-19 pandemic caused a global health crisis directly impacting the healthcare system. Healthcare leaders influence and shape the ability of an organization to cope with and recover from a crisis such as the COVID-19 pandemic. Their actions serve to guide and support nurses' actions through unpredictable health service demands. The purpose of this paper was to examine frontline managers' experiences and organizational leadership responses that activated organizational resilience during the COVID-19 pandemic, and to learn for ongoing and future responses to healthcare crises. Fourteen managers participated in semi-structured interviews. We found that: (1) leadership challenges (physical resources and emotional burden), (2) the influence of senior leader decision-making on managers (constant change, shortage of human resources, adapting care delivery, and cooperation and collaboration), and (3) lessons learned (managerial caring behaviours and role modelling, adaptive leadership, education and training, culture of care for self, and others) were evidence of managers' responses to the crisis. Overall, the study provides evidence of managers experiences during the early waves of the pandemic in supporting nurses and fostering organizational resilience. Knowing manager's experiences can facilitate planning, preparing, and strengthening their leadership strategies to improve work conditions is a high priority to manage and sustain nurses' mental health and wellbeing.

Conventional selective breeding in aquaculture has been effective in genetically enhancing economic traits like growth and disease resistance. However, its advances are restricted by heritability, the extended period required to produce a strain with desirable traits, and the necessity to target multiple characteristics simultaneously in the breeding programs. Genome editing tools like zinc finger nucleases (ZFNs), transcription activator-like effector nucleases (TALENs), and clustered regularly interspaced short palindromic repeats/CRISPR-associated protein 9 (CRISPR/Cas9) are promising for faster genetic improvement in fishes. CRISPR/Cas9 technology is the least expensive, most precise, and well compatible with multiplexing of all genome editing approaches, making it a productive and highly targeted approach for developing customized fish strains with specified characteristics. As a result, the use of CRISPR/Cas9 technology in aquaculture is rapidly growing, with the main traits researched being reproduction and development, growth, pigmentation, disease resistance, trans-GFP utilization, and omega-3 metabolism. However, technological obstacles, such as off-target effects, ancestral genome duplication, and mosaicism in founder population, need to be addressed to achieve sustainable fish production. Furthermore, present regulatory and risk assessment frameworks are inadequate to address the technical hurdles of CRISPR/Cas9, even though public and regulatory approval is critical to commercializing novel technology products. In this review, we examine the potential of CRISPR/Cas9 technology for the genetic improvement of edible fish, the technical, ethical, and socio-economic challenges to using it in fish species, and its future scope for sustainable fish production.

Nowadays, the integration of children with special educational needs into kindergarten is becoming more and more common, which poses a challenge for kindergarten teachers. The care of children with special educational needs, who are brought up in an integrated manner, can be best done through teamwork. Therefore, in our research, we use a questionnaire method to examine how well the kindergarten teachers are prepared for children with special educational needs, how they implement their care, and what the joint work with special education needs teachers is like. 422 kindergarten teachers and 82 special education needs teachers participated in our research. The data were analyzed with the SPSS statistical program, in which cross-tabulation and ANOVA were used. According to our results, kindergarten teachers evaluate the implementation of integration much more positively than special education needs teachers, but better cooperation would require more specialists and more time.

Understanding the molecular mechanisms underlying individual responses to environmental changes is crucial for species conservation and management. Pelagic fishes including Atlantic herring (Clupea harengus) are of particular interest because of their key ecological and economic roles and their susceptibility to a changing ocean from global warming. Temperature and photoperiod have been linked with spawning time and location in adult herring, but no study has thus far investigated the role of environmental factors on gene regulation during the vulnerable early developmental stages. Here, we examine DNA methylation patterns of larval herring bred under two temperatures (11°C and 13°C) and photoperiod (6 and 12 h) regimes in a 2 × 2 factorial design. We found consistently high levels of global methylation across all individuals and a decline in global methylation with increased developmental stage that was more pronounced at 13°C (p ≤ 0.007) than at 11°C (p ≥ 0.21). Most of the differentially methylated sites were in exon and promoter regions for genes linked to metabolism and development, some of which were hypermethylated at higher temperature. These results demonstrate the important role of DNA methylation during larval development and suggest that this molecular mechanism might be key in regulating early‐stage responses to environmental stressors in Atlantic herring.

The significance of plant-derived products in aquaculture lies in their potential to offer sustainable alternatives, promoting eco-friendly practices. This study investigated the impact of nettle (Urtica dioica) leaves powder on the growth efficiency, hemato-biochemical variables and non-specific immune system of rohu, Labeo rohita fingerlings. To achieve this objective, sample average weight (5.23 ± 0.34 g) were categorized into four groups, namely control, T1, T2 and T3 in triplicate and administered diets fortified with nettle in amounts of 0, 1, 3 and 5% respectively for a duration of 60 days. After 60 days of fortified diet, the fish underwent intraperitoneal injection with bacteria (Aeromonas hydrophila), and subsequent relative percentage survival (RPS) was observed. The growth performance, including "weight gain (WG), specific growth rate (SGR), feed conversion ratio (FCR) and feed efficiency ratio (FER)", were notably higher in the T3 group (5%) than in others. The hematological values of White blood cell, hematocrit, and hemoglobin revealed higher levels with a fortified diet. The dietary supplementation of nettle reduced serum cholesterol and glucose concentration, whereas it increased albumin, globulin, and total protein in the fish blood. Enhancements in lysozyme and myeloperoxidase activity were observed in the intervention groups with feed containing nettle supplementation. The nettle diet at a 5% concentration demonstrated a higher RPS than the others following injection with A. hydrophila. The findings indicate the potential of nettle as a valuable nutritional supplement for increasing fish immunological reaction and bolstering pathogen resistance., Competing Interests: Declarations Informed consent Not applicable.

Fish ear bones, known as otoliths, are often collected in fisheries to assist in management, and are a common sample type in museum and national archives. Beyond their utility for ageing, morphological and trace element analysis, otoliths are a repository of valuable genomic information. Previous work has shown that DNA can be extracted from the trace quantities of tissue remaining on the surface of otoliths, despite the fact that they are often stored dry at room temperature. However, much of this work has used reduced representation sequencing methods in clean lab conditions, to achieve adequate yields of DNA, libraries and ultimately single-nucleotide polymorphisms (SNPs). Here, we pioneer the use of small-scale (spike-in) sequencing to screen contemporary otolith samples prepared in regular molecular biology (in contrast to clean) laboratories for contamination and quality levels, submitting for whole-genome resequencing only samples above a defined endogenous DNA threshold. Despite the typically low quality and quantity of DNA extracted from otoliths, we are able to produce whole-genome libraries and ultimately sets of filtered, unlinked and even putatively adaptive SNPs of ample numbers for downstream uses in population, climate and conservation genomics. By comparing with a set of tissue samples from the same species, we are able to highlight the quality and efficacy of otolith samples from DNA extraction and library preparation, to bioinformatic preprocessing and SNP calling. We provide detailed schematics, protocols and scripts of our approach, such that it can be adopted widely by the community, improving the use of otoliths as a source of valuable genomic data., (© 2024 The Author(s).

The Eurasian perch (Perca fluviatilis Linnaeus, 1758) is native to almost entire Eurasia. For over the last two decades, this species became an important candidate for intensive freshwater aquaculture due to its high consumer's acceptance and overall market value. Hence, the intensive production of Eurasian perch has increased considerably allowing effective domestication; there is still a need for the development of effective selective breeding programmes allowing its further expansion. This process, in turn, can be significantly facilitated by molecular genetics. The genetic information of Eurasian perch and its populations is limited. Up to date information of regarding genetic diversity of many populations is still missing, including microsatellites for Eurasian perch, which could be useful during the selective breeding programmes allowing parental assignment and/or to follow heritability of desired traits. In this study, we have developed and characterized new polymorphic microsatellites. Subsequently, those 12 markers have been used further to compare two Hungarian and one Polish Eurasian perch populations. The Hungarian stocks had high genetic similarity (with low diversity), as we assumed, while the Polish population differed significantly. All populations deviated significantly from the Hardy-Weinberg equilibrium, and heterozygote deficiency was detected in all, showing the presence of an anthropogenic effect., (© 2021.

Anthropogenic climate change is projected to affect marine ecosystems by challenging the environmental tolerance of individuals. Marine fishes may be particularly vulnerable to emergent climate stressors during early life stages. Here we focus on embryos of Pacific herring (Clupea pallasii), an important forage fish species widely distributed across the North Pacific. Embryos were reared under a range of temperatures (10-16°C) crossed with two pCO2 levels (600 and 2000 matm) to investigate effects on metabolism and survival. We further tested how elevated pCO2 affects critical thermal tolerance (CTmax) by challenging embryos to short-term temperature fluctuations. Experiments were repeated on embryos collected from winter and spring spawning populations to determine if spawning phenology corresponds with different limits of environmental tolerance in offspring. We found that embryos could withstand acute exposure to 20°C regardless of spawning population or incubation treatment, but that survival was greatly reduced after 2-3 hours at 25°C. We found that pCO2 had limited effects on CTmax. The survival of embryos reared under chronically warm conditions (12°, 14°, or 16°C) was significantly lower relative to 10°C treatments in both populations. Oxygen consumption rates (MO2) were also higher at elevated temperatures and pCO2 levels. However, heart contraction measurements made 48 hours after CTmax exposure revealed a greater increase in heart rate in embryos reared at 10°C compared to 16°C, suggesting acclimation at higher incubation temperatures. Our results indicate that Pacific herring are generally tolerant of pCO2 but are vulnerable to acute temperature stress. Importantly, spring-spawning embryos did not clearly exhibit a higher tolerance to heat stress compared to winter offspring. [ABSTRACT FROM AUTHOR]

Genetic variation is instrumental for adaptation to changing environments but it is unclear how it is structured and contributes to adaptation in pelagic species lacking clear barriers to gene flow. Here, we applied comparative genomics to extensive transcriptome datasets from 20 krill species collected across the Atlantic, Indian, Pacific, and Southern Oceans. We compared genetic variation both within and between species to elucidate their evolutionary history and genomic bases of adaptation. We resolved phylogenetic interrelationships and uncovered genomic evidence to elevate the cryptic Euphausia similis var. armata into species. Levels of genetic variation and rates of adaptive protein evolution vary widely. Species endemic to the cold Southern Ocean, such as the Antarctic krill Euphausia superba , showed less genetic variation and lower evolutionary rates than other species. This could suggest a low adaptive potential to rapid climate change. We uncovered hundreds of candidate genes with signatures of adaptive evolution among Antarctic Euphausia but did not observe strong evidence of adaptive convergence with the predominantly Arctic Thysanoessa. We instead identified candidates for cold-adaptation that have also been detected in Antarctic fish, including genes that govern thermal reception such as TrpA1. Our results suggest parallel genetic responses to similar selection pressures across Antarctic taxa and provide new insights into the adaptive potential of important zooplankton already affected by climate change.

Background: During deployment, veterans of the 1991 Gulf War (GW) were exposed to multiple war-related toxicants. Roughly a third of these veterans continue to exhibit neurotoxicant induced symptoms of Gulf War Illness (GWI), a multi-faceted condition that includes fatigue, pain and cognitive decrements. When studied empirically, both deployed veterans with exposures and those who meet the criteria for GWI are more likely to show deficits in the area of neuropsychological functioning. Although studies have shown cognitive impairments in small sample sizes, it is necessary to revisit these findings with larger samples and newer cohorts to see if other areas of deficit emerge with more power to detect such differences. A group of researchers and clinicians with expertise in the area of GWI have identified common data elements (CDE) for use in research samples to compare data sets. At the same time, a subgroup of researchers created a new repository to share these cognitive data and biospecimens within the GWI research community. Methods: The present study aimed to compare cognitive measures of attention, executive functioning, and verbal memory in a large sample of GWI cases and healthy GW veteran controls using neuropsychological tests recommended in the CDEs. We additionally subdivided samples based on the specific neurotoxicant exposures related to cognitive deficits and compared exposed versus non-exposed veterans regardless of case criteria status. The total sample utilized cognitive testing outcomes from the newly collated Boston, Biorepository, Recruitment, and Integrative Network (BBRAIN) for GWI. Results: Participants included 411 GW veterans, 312 GWI (cases) and 99 healthy veterans (controls). Veterans with GWI showed significantly poorer attention, executive functioning, learning, and short-and-long term verbal memory than those without GWI. Further, GW veterans with exposures to acetylcholinesterase inhibiting pesticides and nerve gas agents, had worse performance on executive function tasks. Veterans with exposure to oil well fires had worse performance on verbal memory and those with pyridostigmine bromide anti-nerve gas pill exposures had better verbal memory and worse performance on an attention task compared to unexposed veterans. Conclusions: This study replicates prior results regarding the utility of the currently recommended CDEs in determining impairments in cognitive functioning in veterans with GWI in a new widely-available repository cohort and provides further evidence of cognitive decrements in GW veterans related to war-related neurotoxicant exposures.

Euphausiids are an ecologically significant and abundant group of marine zooplankton that form key links between primary producers and consumers in pelagic food webs throughout the world ocean. The euphausiid species, Thysanoessa inermis and T. raschii, have boreal-Arctic distributions, occurring in the North Atlantic, North Pacific, and Arctic Oceans. The species differ in depth ranges and habitat preferences: T. raschii is found in coastal waters on continental shelf habitats, while T. inermis is abundant in slope and deep water regions. Population genetic analysis based on DNA sequence variation of the mitochondrial cytochrome oxidase I (COI) barcode region was carried out for identified specimens of T. inermis and T. raschii collected in the Arctic (Beaufort/Chukchi and Norwegian Seas, Svalbard Area) and North Atlantic (Gulf of St. Lawrence, Labrador Sea, Iqaluit, Hudson Bay). Populations of T. inermis in the N. Atlantic showed high connectivity, but were genetically isolated from the Beaufort/Chukchi Sea population. Population genetic diversity of T. inermis showed high haplotype and nucleotide diversity and no departures from neutral expectations. In contrast, T. raschii showed lower haplotype and nucleotide diversity, with highly significant departures from neutral expectations. A possible hypothesis is that T. raschii experienced a significant historical demographic event (e.g., population bottleneck), while T. inermis maintained a stable population over recent evolutionary history. The results provide new insights into population dynamics and implications for responses to climate change of these key euphausiid species for the Arctic Ocean. [ABSTRACT FROM AUTHOR]

Simple Summary: This study concerns evaluation of the possible negative effects of power plants as one of the most important objects generating environmental pollution in aquatic ecosystems. We attempted to research the intraspecific genetic diversity of a naturally distributed fish species, Eurasian perch, based on a comparison of its mitochondrial DNA sequences. To distinguish naturally occurring mutagenesis from DNA changes caused by thermal or chemical pollution, the molecular data representing patterns of perch populations inhabiting hydro-systems profoundly affected by power plants and non-affected perch populations were collected and analysed. The obtained results indicate that most genetic differences among perch populations representing a large geographic area that encompasses territories from the Baltic Sea to Ukraine could be explained by historical and ongoing natural processes instead of pollution from power plants. The intraspecific genetic diversity of freshwater fish inhabiting hydro-systems of the macrogeographic area spreading from the Black to Baltic Seas requires comprehensive investigation from fundamental and practical perspectives. The current study focused on the involvement of the mtDNA ATP6 region in the adaptability and microevolution of Perca fluviatilis within phylogeographic and anthropogenic contexts. We sequenced a 627 bp fragment encompassing the ATP6 region and used it for genetic analysis of 193 perch caught in Latvia, Lithuania, Belarus, and Ukraine, representing natural and anthropogenically impacted populations. We evaluated patterns of intraspecific genetic diversity in the ATP6 region and phylogeographic trends within the studied area compared with previously established D-loop trends. Evaluation of ATP6 coding sequence variability revealed that among 13 newly detected haplotypes, only two were caused by non-synonymous substitutions of amino acids of the protein. PCoA revealed three genetic groups (I–III) based on the ATP6 region that encompassed four previously described genetic groups established based on the mtDNA D-loop. The two mtDNA regions (D-loop and ATP6) have microevolved at least partially independently. Prolonged anthropogenic impacts may generate new point mutations at the ATP6 locus, but this phenomenon could be mainly concealed by natural selection and reparation processes.

Synchrotron radiation based on Fourier transform infrared radiation (SR-FTIR), X-ray fluorescence (XRF) and attenuated total reflection based on Fourier transform infrared radiation (ATR-FTIR) spectroscopy are both fast determining and minimal sample preparing techniques. They are capable of detecting the internal molecular structures. However, these techniques are still not well understood by nutrition researchers for the analysis of feed. The purpose of this review is to introduce advanced SR-FTIR, XRF, and ATR-FTIR molecular techniques, use these techniques to study chemical and nutrient profiles of Avena sativa grain, and lastly to study the nutrition and structure interactive association properties. The review mainly focuses on the following aspects: 1) the background information of Avena sativa grain; its history, chemical composition, nutrient profile, inherent structure, and production; 2) molecular spectroscopic techniques; principles and spectral analysis methodology of SR-FTIR, XRF and ATR-FTIR; 3) the application of SR-FTIR, XRF, and ATR-FTIR as a novel approach. This review provides an insight on how molecular spectroscopic techniques could be used for the study of nutrition and structure interactive association properties [ABSTRACT FROM AUTHOR]

Eurasian perch Perca fluviatilis has been a popular model species for decades in the fields of aquatic ecology, community dynamics, behaviour, physiology and ecotoxicology. Yet, despite extensive research, the progress of integrating genomic perspective into existing ecological knowledge in perch has been relatively modest. Meanwhile, the emergence of high‐throughput sequencing technologies has completely changed the methods for genetic variation assessment and conducting biodiversity and evolutionary research. During the last 5 years, three genome assemblies of P. fluviatilis have been generated, allowing substantial advancement of our understanding of the interactions between ecological and evolutionary processes at the whole‐genome level. We review the past progress, current status and potential future impact of the genomic resources and tools for ecological research in Eurasian perch focusing on the utility of recent whole‐genome assemblies. Furthermore, we demonstrate the power of genome‐wide approaches and newly developed tools and outline recent cases where genomics have contributed to new ecological and evolutionary knowledge. We explore how the availability of reference assembly enables the efficient application of various statistical tools, and how genomic approaches can provide novel insights into resource polymorphism, host–parasite interactions and to genetic and phenotypic changes associated with climate change and harvesting‐induced evolution. In summary, we call for increased integration of genomic tools into ecological research for perch, as well as for other fish species, which is likely to yield novel insights into processes linking the adaptation and plasticity to ecosystem functioning and environmental change.
