Increasing parent help-seeking for child mental health: A study protocol for the growing minds check-in, an online universal screening tool.

Background: Early identification and intervention for mental health (MH) problems in childhood offers lifelong benefits. Many children with MH problems do not receive appropriate help. To address this need, an online universal MH screening tool, the Growing Minds Check-In for parents/caregivers (GMCI-P), was developed to provide feedback to parents on their children's MH, identify children at risk of MH problems, and link parents to evidence-based online programs/information, with the goal of facilitating parent help-seeking, and ultimately reducing the prevalence of child MH problems.

Systems analysis of miR-199a/b-5p and multiple miR-199a/b-5p targets during chondrogenesis.

Changes in chondrocyte gene expression can contribute to the development of osteoarthritis (OA), and so recognition of the regulative processes during chondrogenesis can lead to a better understanding of OA. microRNAs (miRNAs) are key regulators of gene expression in chondrocytes/OA, and we have used a combined experimental, bioinformatic, and systems biology approach to explore the multiple miRNA-mRNA interactions that regulate chondrogenesis. A longitudinal chondrogenesis bioinformatic analysis identified paralogues miR-199a-5p and miR-199b-5p as pro-chondrogenic regulators.

Systematic transcriptomic analysis and temporal modelling of human fibroblast senescence.

Cellular senescence is a diverse phenotype characterised by permanent cell cycle arrest and an associated secretory phenotype (SASP) which includes inflammatory cytokines. Typically, senescent cells are removed by the immune system, but this process becomes dysregulated with age causing senescent cells to accumulate and induce chronic inflammatory signalling. Identifying senescent cells is challenging due to senescence phenotype heterogeneity, and senotherapy often requires a combinatorial approach.

Modelling the spatiotemporal dynamics of senescent cells in wound healing, chronic wounds, and fibrosis.

Cellular senescence is known to drive age-related pathology through the senescence-associated secretory phenotype (SASP). However, it also plays important physiological roles such as cancer suppression, embryogenesis and wound healing. Wound healing is a tightly regulated process which when disrupted results in conditions such as fibrosis and chronic wounds.

Cell Senescence-Independent Changes of Human Skin Fibroblasts with Age.

Skin ageing is defined, in part, by collagen depletion and fragmentation that leads to a loss of mechanical tension. This is currently believed to reflect, in part, the accumulation of senescent cells. We compared the expression of genes and proteins for components of the extracellular matrix (ECM) as well as their regulators and found that in vitro senescent cells produced more matrix metalloproteinases (MMPs) than proliferating cells from adult and neonatal donors.
