[Sharing information and respecting confidentiality: Standards for improving the quality of mental health services].

Objectives Collaboration between family caregivers and professionals plays a critical role in the recovery of the person living with a mental health disorder. However, collaborative practices between family caregivers and professionals are impeded by issues relating to confidentiality, particularly in connection with bidirectional information sharing between the parties involved. In doing so, these issues affect the quality of mental health services.

Short-term post-implantation dynamics of in vitro engineered human microvascularized adipose tissues.

Engineered adipose tissues are developed for their use as substitutes for tissue replacement in reconstructive surgery. To ensure a timely perfusion of the grafted substitutes, different strategies can be used such as the incorporation of an endothelial component. In this study, we engineered human adipose tissue substitutes comprising of functional adipocytes as well as a natural extracellular matrix using the self-assembly approach, without the use of exogenous scaffolding elements.

Impact of TNF and IL-1β on capillary networks within engineered human adipose tissues.

Inflammation is a normal phase of the wound healing process, which likely occurs following tissue transplantation. For reconstructive surgery purposes, engineered adipose tissues represent promising alternatives to autologous fat grafts. It is therefore important to study the impact of an inflammatory microenvironment on the cellular functions of the different cell types comprised within matrix-rich reconstructed tissues.

Characterization of In Vitro Engineered Human Adipose Tissues: Relevant Adipokine Secretion and Impact of TNF-α.

Representative modelling of human adipose tissue functions is central to metabolic research. Tridimensional models able to recreate human adipogenesis in a physiological tissue-like context in vitro are still scarce. We describe the engineering of white adipose tissues reconstructed from their cultured adipose-derived stromal precursor cells.

Magnetic Resonance Imaging of Human Tissue-Engineered Adipose Substitutes.

Adipose tissue (AT) substitutes are being developed to answer the strong demand in reconstructive surgery. To facilitate the validation of their functional performance in vivo, and to avoid resorting to excessive number of animals, it is crucial at this stage to develop biomedical imaging methodologies, enabling the follow-up of reconstructed AT substitutes. Until now, biomedical imaging of AT substitutes has scarcely been reported in the literature.

Creating capillary networks within human engineered tissues: impact of adipocytes and their secretory products.

The development of tissue-engineered substitutes of substantial volume is closely associated with the need to ensure rapid vascularization upon grafting. Strategies promoting angiogenesis include the in vitro formation of capillary-like networks within engineered substitutes. We generated both connective and adipose tissues based on a cell sheet technology using human adipose-derived stromal cells.

Dynamic culture induces a cell type-dependent response impacting on the thickness of engineered connective tissues.

Mesenchymal cells are central to connective tissue homeostasis and are widely used for tissue-engineering applications. Dermal fibroblasts and adipose-derived stromal cells (ASCs) allow successful tissue reconstruction by the self-assembly approach of tissue engineering. This method leads to the production of multilayered tissues, devoid of exogenous biomaterials, that can be used as stromal compartments for skin or vesical reconstruction.

Overexpression of PAX5 induces apoptosis in multiple myeloma cells.

PAX5 is an essential transcription factor for the commitment of lymphoid progenitors to the B-lymphocyte lineage. PAX5 suppression results in retrodifferentiation of B lymphocytes to an uncommitted progenitor cell stage, whereas PAX5 suppression in mature B lymphocytes leads to further development into plasma cells. Here, we have analyzed the fate of plasma cell lines following PAX5 reexpression.

2-Methoxyestradiol induce the conversion of human peripheral blood memory B lymphocytes into plasma cells.

2-Methoxyestradiol (2ME), an end-metabolite of 17beta-estradiol, is an antiproliferative agent that is currently being tested in clinical trials for cancer treatment. We hereby report that sub-cytotoxic concentrations of 2ME influence the in vitro proliferation of human peripheral blood B lymphocytes. More surprisingly, we have observed that 2ME induces the conversion of CD138(-) B lymphocytes into CD138(+) cells of phenotype similar to immunoglobulin (Ig)-secreting plasma cells.
