Background: The work experience of seafarers differs significantly from other land-based occupations due to several factors, particularly remoteness and the restricted work environment. This study seeks to examine the impact of burnout and health impairment in the maritime industry, using the Job Demand-Resources theory as a framework.
Methods: To investigate these phenomena, an online questionnaire was sent to 239 Italian seafarers (94.6% men, Mage = 39.44, SD = 12.8). We tested a mediated Structural Equation Model (SEM) aimed at predicting negative health outcomes.
Results: The results show that burnout plays a mediating role between job demands (such as workload and cognitive strain) and resources (such as social support and transformational leadership), influencing variables related to health impairment (such as sleep quality and physical well-being). Furthermore, the findings highlight the direct influence of occupational resources on seafarers' health.
Conclusions: The discussion highlights the urgent need for more research in the field of organisational psychology in the maritime industry and the discrepancies between these findings, which are consistent with the existing maritime literature, and other studies that do not include seafarers in their sample groups.

Polystyrene nanoparticles pose significant toxicological risks to aquatic ecosystems, yet their impact on zebrafish ( ) embryonic development, particularly erythropoiesis, remains underexplored. This study used single-cell RNA sequencing to comprehensively evaluate the effects of polystyrene nanoparticle exposure on erythropoiesis in zebrafish embryos. validation experiments corroborated the transcriptomic findings, revealing that polystyrene nanoparticle exposure disrupted erythrocyte differentiation, as evidenced by the decrease in mature erythrocytes and concomitant increase in immature erythrocytes.

Small RNAs (sRNAs) are a class of molecules capable of perceiving environmental changes and exerting post-transcriptional regulation over target gene expression, thereby influencing bacterial virulence and host immune responses. is a pathogenic bacterium that poses a significant threat to aquatic animal health. However, the regulatory mechanisms of sRNAs in .

Background: Iron is an essential micronutrient for cell survival and growth; however, excess of this metal drives ferroptosis. Although maternal iron imbalance and placental hypoxia are independent contributors to the pathogenesis of preeclampsia, a hypertensive disorder of pregnancy, the mechanisms by which their interaction impinge on maternal and placental health remain elusive.
Methods: We used placentae from normotensive and preeclampsia pregnancy cohorts, human H9 embryonic stem cells differentiated into cytotrophoblast-like cells, and placenta-specific preeclamptic mice.

Objective: Time distortions characterise severe mental disorders, exhibiting different clinical and neurobiological manifestations. This systematic review aims to explore the existing literature encompassing experimental studies on time perception in patients with bipolar disorder (BD), considering psychopathological and cognitive correlates.
Methods: Studies using an experimental paradigm to objectively measure the capacity to judge time have been searched for.
