In experimental pain studies involving animals, subjective pain reports are not feasible. Current methods for detecting pain-related behaviors rely on human observation, which is time-consuming and labor-intensive, particularly for lengthy video recordings. Automating the quantification of these behaviors poses substantial challenges.

Selenium is an essential trace element presented in selenoproteins, many of which are strong antioxidant enzymes. Selenium nanoparticles (SeNPs) have been reported to promote tissue repair due to their anti-oxidative, anti-inflammatory, anti-apoptotic, and differentiation-modulating properties.

Methods: Mice were fed with standard chow (SC) or HFD for 12 weeks.
Skin-resident regulatory T cells (Tregs) play an irreplaceable role in orchestrating cutaneous immune homeostasis and repair, including the promotion of hair regeneration via the Notch signaling ligand Jagged-1 (Jag1). While skin Tregs are indispensable for facilitating tissue repair post-wounding, it remains unknown if Jag1-expressing skin Tregs impact wound healing. Using a tamoxifen inducible Foxp3Jag1 model, we show that loss of functional Jag1 in Tregs significantly delays the rate of full-thickness wound closure.

Fatty acid binding protein 4 (FABP4) is a pro-inflammatory adipokine mediating various metabolic and inflammatory diseases. This study aimed to examine the expression of FABP4 and its association with the expressions of inflammatory cytokines in tendinopathy.

This study aimed to establish a mouse inflammatory and degenerative patellar tendon injury model, which will facilitate research on patellar tendinopathy using advanced molecular tools including transgenic models. Collagenase at different doses (low dose (LD), medium dose (MD), high dose (HD)) or saline was injected over the mouse patellar tendon.

However, even after completing the rehabilitation programme, some patients may have persistent quadriceps muscle weakness affecting knee function which ultimately leads to a failure in returning to play. Vitamin D has been long recognized for its musculoskeletal effects.

However, a large proportion of women and men are unscreened. Aim This review aims to provide an overview of the literature regarding the determinants of cancer screening participation among target groups in Queensland.

Objectives: Racial discrimination experiences contribute to health disparities and can influence individuals' health. Yet, pathways by which discrimination-related experiences affect alcohol craving remain understudied using experimental designs. Additionally, limited research has examined possible differential effects of "major" discrimination and microaggression experiences in everyday life on alcohol craving.

Although remarkable progress has been made to construct complex multifunctional artificial cells, there are still significant differences between artificial cells and natural cells. It is therefore important to understand the techniques and challenges for the fabrication of artificial cells and their applications for further technological advancement.

We have previously identified CD141CD14 DDCs as a skin-resident immunoregulatory population that is vitamin-D (VitD3) inducible from monocyte-derived DCs (moDCs), termed CD141 VitD3 moDCs. We demonstrate that CD141 DDCs and CD141 VitD3 moDCs share key immunological features including cell surface markers, reduced T cell stimulation, IL-10 production, and a common transcriptomic signature.

The altered fate of plantar fascia stem/progenitor cells (PFSCs) under overuse-induced inflammation might contribute to the pathogenesis. This study aimed to isolate rat PFSCs and compared their stem cell-related properties with bone marrow stromal cells (BMSCs).

Introduction: Acculturation and enculturation have been conceptualized, respectively, as risk and protective factors for cigarette use. Although acculturation/enculturation orientations are often studied as stable characteristics, they represent a dynamic process influenced by individuals' social environments and can fluctuate across time. Therefore, investigating how youth actively navigate their acculturation and enculturation beliefs and behaviors on a day-to-day basis can advance scientific understanding of factors related to cigarette use.

Drinking motives are well-established predictors of alcohol use and negative alcohol consequences. Given the influence of context on drinking practices, motives specific to pregaming may affect pregaming behaviors and outcomes above and beyond general drinking motives.

However, cell viability, stability, and potential uncontrolled actions create challenges for clinical translation. The decellularization of cell sheets may overcome these problems as studies have shown that the natural extracellular matrix of stem cells is bioactive and can promote tissue repair.
