Dishevelled family proteins (DVL1, DVL2, and DVL3) are cytoplasmic proteins that are involved in canonical and non-canonical Wnt signaling pathway during embryonic development. The role of DVL proteins in the placental tissue remains mostly unknown. In the current study, we explored the role of Dishevelled proteins in naturally invasive tissue, trophoblast. Formalin-fixed paraffin-embedded samples of 15 term placentas from physiologic term pregnancies and 15 term placentas from pregnancies complicated with intrauterine growth restrictions (IUGR) were used for the study. Expression levels of mRNA for DVL1, DVL2, and DVL3 in placentas were analyzed by quantitative real-time PCR (qRTPCR). DVL1, DVL2, and DVL3 protein expression were semi-quantitatively analyzed using immunohistochemistry. The expression of DVL2 and DVL3 proteins was significantly higher in trophoblasts in placental villi from IUGR pregnancies compared with the control group of term placentas. In contrast, DVL3 protein expression was significantly higher in endothelial cells in placental villi from IUGR pregnancies compared with normal term placentas. The observed differences at protein levels between normal and IUGR placentas were not confirmed at the mRNA levels of DVL genes. Our data indicate the active involvement of DVL proteins in IUGR-related placentas. No significant changes were observed in DVL mRNA levels between the two groups of placentas. Further studies are required to explore the clinical relevance of these observations.Protein crystallographers are well aware of the trap of crystallizing E. coli proteins instead of the macromolecule of interest if heterologous recombinant protein expression in E. Olaparib coli was part of the experimental pipeline. Among the well-known culprits are YodA metal-binding lipocalin (25 kDa) and YadF carbonic anhydrase (a tetramer of 25 kDa subunits). We report a novel crystal form of another such culprit, E. coli HPII catalase, which is a tetrameric protein of ~340 kDa molecular weight. HPII is likely to contaminate recombinant protein samples, co-purify, and then co-crystallize with the target proteins, especially if their masses in size exclusion chromatography are ~300-400 kDa. What makes this case more interesting but also parlous, is the fact that HPII can crystallize from very low concentrations, even well below 1 mg/mL.Older people living with a major neurocognitive disorder often have difficulty communicating. They may exhibit reactive behaviors, such as vocal or aggressive behaviors, which are manifestations of malaise. These behaviors have consequences for these older people, as well as for their relatives and formal caregivers. This article discusses the relationship-centered approach to improving the experience of each of these persons by stimulating a reflection on what unites us. Then, the principles of this relationship-centered approach are outlined, based on the unique needs of each person, the reciprocity of their relationship, and their common aspirations. The application of these principles to older people living with a neurocognitive disorder who exhibit reactive behaviors is reflected through the adoption of consistent language, the identification of the meanings of behaviors and personalized actions, and the establishment of a care partnership. An example of a process integrating this approach is presented, as well as its possible effects. The adoption of this approach may present several challenges in care settings. To meet these challenges, implementation strategies are described promoting the adoption of this approach and contributing to everyone’s well-being.Nurses have a leading role in weaning patients from mechanical ventilation (WMV) given their constant presence and their continuous monitoring. To promote proper WMV, nurses must exercise autonomy and be involved in decision-making. However, in certain care contexts, there is little involvement of nurses. The purpose of this text is to establish the characteristics of the concept of autonomous decision-making applied to nursing during WMV. An analysis of this concept was carried out according to the evolutionary method of Rodgers. The identification of the attributes, antecedents, and consequences made it possible to note ambiguity in the definition of this concept. Nurses use autonomous decision-making for the execution of assigned tasks and when they make decisions according to a pre-prescribed decision-making algorithm. Significant foundations for the decision-making autonomy of critical care nurses during WMV emerged from this analysis  scope of practice, in-depth knowledge of the patient, and commitment to the success of WMV. Participation in interdependent decision-making allows nurses to bring the patient’s perspective into decisions. Avenues of reflection have also emerged, including decisions based on evidence to provide new avenues for autonomous decision-making.Introduction  A discussion paper based on a teaching experience, and presenting a reflective viewpoint developed as part of the university nursing course Theory in Nursing.Context  A critical look at the historiography and reference works used in nursing courses.Objectives  To shed new light on the foundations of the nursing discipline by seeking to better integrate the participation of religious communities in the development of nursing knowledge.Method  Analysis of articles from Recherche en soins infirmiers and a reflective approach influenced by an interdisciplinary perspective linking nursing science, history, and the contribution of Pierre Bourdieu’s work.Results  Observation of the complete absence of contributions to nursing knowledge before Florence Nightingale (1820-1910) and of a century-long silence after her.Discussion  Analysis of the observed reflex to disavow the legacy of nursing sisters in Quebec through the analysis of three aspects  the Nightingalian episteme, the historiographical positioning of nurses and historians, and the construction of knowledge based on the experience of the Sisters of Providence at the Hôpital Saint-Jean-de-Dieu.Conclusion  By ignoring the Franco-Catholic origin of the scientific field of nursing, this disciplinary knowledge deprives itself of a powerful nursing model.
