Impact of a national dementia research consortium: The Canadian Consortium on Neurodegeneration in Aging (CCNA).

The Canadian Consortium on Neurodegeneration in Aging (CCNA) was created by the Canadian federal government through its health research funding agency, the Canadian Institutes for Health Research (CIHR), in 2014, as a response to the G7 initiative to fight dementia. Two five-year funding cycles (2014-2019; 2019-2024) have occurred following peer review, and a third cycle (Phase 3) has just begun. A unique construct was mandated, consisting of 20 national teams in Phase I and 19 teams in Phase II (with research topics spanning from basic to clinical science to health resource systems) along with cross-cutting programs to support them.

Formulating recommendations to improve care for persons living with dementia: deliberative dialogues with multiple stakeholders in the province of Quebec, Canada.

Background: Persons living with dementia and their care partners encounter many challenges within the health and social care system, including lack of information, support, counselling, and access to community services, as well as significant staff turnover in home care services. The objective of this study was to work with multiple stakeholders to formulate relevant and feasible recommendations to improve care for persons living with dementia and their care partners in Quebec, Canada.

Methods: We conducted deliberative dialogues in the context of a large mixed methods study on the care of persons living with dementia and care partners.

Direct ladderization of cyclooctatetraene-containing, processable conjugated ladder polymers from annulated bis-zirconacyclopentadienes.

Conjugated ladder polymers (CLPs) are difficult yet captivating synthetic targets due to their fully unsaturated fused backbones. Inherent challenges associated with their synthesis often lead to low yields, structural defects, and insoluble products. Here a new method to form CLPs is demonstrated, utilizing a high-yielding dimerization of annulated zirconacyclopentadienes to form cyclooctatetraene (COT) monomer units.

Homeostatic Functions of Tissue-Resident Macrophages and Their Role in Tissue Maintenance.

Tissue-resident macrophages are best known for their indispensable role in immunological reactions, where they contribute to immune defense and resolution of inflammation. However, recent studies have also uncovered that they provide crucial tissue-specific functions that support organ homeostasis and maintenance. Accordingly, defects in macrophage function or development can disrupt the delicate balance of organ homeostasis, leading to pathological conditions.
