We describe new insights into the morphology and life history of the bizarre parasite Haplozoon axiothellae (Dinoflagellata) using light microscopy (LM), scanning electron microscopy (SEM), and confocal laser scanning microscopy (CLSM). Trophonts were isolated from the intestines of host maldanid polychaetes, Axiothella rubrocincta, collected from San Juan Island, Washington, USA. LM and SEM confirmed features previously observed, such as amphiesmal projections, mature and immature junctions between the nucleated compartments of the vermiform syncytium and visible polygonal alveoli. CLSM of adult trophonts fluorescently stained for DNA, tubulin, centrin, and plasma membrane demonstrated several new ultrastructural traits (1) an extensive basket of parallel microtubules within the trophomere used for host attachment, (2) two physically separated MTOCs (i.e. putative pairs of basal bodies) beneath pores on the ventral side of each compartment, (3) robust mitotic and/or meiotic spindles associated with one to four nuclei in each compartment, (4) spindles with polar bodies that are disconnected from the MTOCs, (5) a centrin-stained fibril within the trophomeres that potentially functions to retract the motile stylet, and (6) cytokinesis in the posterior-most compartments. This study renames haplozoan compartments using the suffix "-mere" rather than "-cyte" (i.e. trophomere, gonomere, sporomere) to reflect their status within a single syncytium.The purpose of this study was to compare the physical properties and cytocompatibility of contemporary calcium silicate-based sealers. Four calcium silicate-based sealers (BrightEndo MTA sealer, CeraSeal, EndoSeal TCS and One-Fil) were compared to an epoxy resin-based sealer (AH Plus). Flow, setting time, radiopacity and dimensional change were evaluated according to ISO 6876 standards. Cytotoxicity on human periodontal ligament fibroblast (hPDLF) cells was compared for biological properties using MTT assay. The surface of the sealer was analysed using scanning electron microscopy to evaluate cell attachment. Flow and radiopacity of all sealers met ISO standards, while setting time and dimensional stability did not meet the ISO standards. Calcium silicate-based sealers showed favourable cytocompatibility, and hPDLF cells were well attached to the calcium silicate-based sealers. this website Calcium silicate-based sealers have clinically acceptable flow and radiopacity, and cytocompatibility. However, these sealers had longer setting time and higher dimensional change than those required by ISO 6876.Working in a stressful environment, child protection workers (CPWs) are often victims of psychological and physical acts of aggression perpetrated by their clients. This can be emotionally distressing for CPWs. Previous authors have suggested that this distress could place CPWs at greater risk for subsequent victimisation if they become emotionally unavailable to their clients. This study sought to investigate whether the distress experienced after an act of client aggression or other types of potentially traumatic events could indeed predict subsequent victimisation over time. Using cross-lagged panel analysis, researchers administered standardised questionnaires to 173 CPWs who had experienced an act of client aggression or other type of potentially traumatic event in the month prior. Participants were asked to fill out additional questionnaires 2, 6 and then 12 months later. Researchers found that CPW distress did in fact predict subsequent victimisation at the 2-month time point only. Researchers then conducted a generalised linear model analysis to test the influence of sociodemographic variables and the moderating influence of supervisor support. Supervisor support did not moderate the relationship between initial distress levels and increased aggression 2 months later. The study concludes by examining how the emotional distress of CPWs can negatively impact clients and how organisations can best provide support, in part, by rethinking aggression prevention.Distress secondary to the COVID-19 pandemic has been substantial, especially in vulnerable Latinx communities who are carrying an undue share of the pandemic-related social, health and economic burden in the United States. In collaboration with 43 community health workers (CHWs) and Promotor/as serving the needs of underserved Latinx communities in South Texas and guided by principles of community-based participatory research (CBPR), the purpose of this study was to identify relevant mental health stressors and related consequences, and to identify strategies for coping with distress among underserved Latinx communities during the COVID-19 pandemic. Data were collected on July 2020 using mixed methods to obtain more in-depth information. Surveys were administered, and three focus groups were conducted. Quantitative data were analysed using descriptive statistics, whereas qualitative data were analysed systematically by starting with a priori questions and themes followed by data categorisation, reduction, dis influence their effectiveness.Working in agriculture may cause serious health problems due to heavy working conditions and chemical exposure. This Husserlian phenomenological qualitative study was conducted with 22 women working in greenhouse agriculture to investigate the health and social problem(s). In the evaluation of the data, Colaizzi's seven-step content analysis method and thematic analysis were used. The Kappa analysis was performed with two independent experts to measure the reliability of comparative fit, and the value obtained in the analysis was 1.00 (perfect fit). Based on the content analysis, six themes were defined. All participants indicated that they had different reproductive health-related problems. Some participants stated that their children had respiratory system-related problems and that they were subjected to physical, verbal/emotional and sexual violence by their husbands. It is important to provide health education, counselling services and screening programmes for women who work in greenhouse agriculture and thus are in the at-risk group for poor health.
