In this review, we comprehensively discuss the approaches of hydrogel-based strategy for CLI treatment as well as their challenges, and future directions.Osteoarthritis (OA) is one of the most common joint diseases worldwide and the focus is shifting to disease prevention and the pharmaceutical and surgical treatment of early OA. However, at present few have proven ability to block or delay the progression of OA. Nevertheless, M2 macrophages present an anti-inflammatory function and promote cartilage repair, thereby alleviating OA in mice. However, it is a significant challenge to regulate the helpful secretion of M2 macrophages on demand toward disease-modifying osteoarthritis therapeutics. Here, artificial M2 macrophage (AM2M) with yolk-shell structure was proposed and fabricated to enhance the therapeutic efficacy of M2 macrophages in the treatment of OA. AM2M was composed of macrophage membrane as "shell" and inflammation-responsive nanogel as "yolk". The nanogel was prepared via physical interaction of gelatin and chondroitin sulfate (ChS) through ionic bond and hydrogen bond, achieving burst release to down-regulate inflammation during acute flares and sustainable release to repair cartilage during low inflammatory activity. Furthermore, AM2M exhibited the targeting and long-term residence in the inflamed area and blocked the immune stimulation of macrophages by ChS. Therefore, our fabrication provided a new insight that artificial M2 macrophages are expected to break a vicious and self-perpetuating cycle of OA.Recent progress in mechanobiology sheds light on the regulation of cellular phenotypes by dissipative property of matrices, i.e., viscosity, fluidity, and stress relaxation, in addition to extensively studied elasticity. However, most researches have focused on bulk mechanics, despite cells in 2D culture can only interact with matrix interface directly. Here, we studied the impact of interfacial viscosity as well as elasticity of substrates on the early stage of adhesion behaviors of epithelial cells through new material design and mechanical characterization. The materials are copolymers of ε-caprolactone and d,l-lactide photocrosslinked by benzophenone. The substrate viscoelasticity changes depending on the polymer molecular weight and irradiation time. The interfacial elasticity and relaxation were determined by atomic force microscopy with modes of nanoindentation and tip-dwelling, respectively. MDCK cells changed morphologically, ranging from loose beaded assembly to more compact spheroids and eventual spread monolayer clusters, in response to the interfacial viscoelasticity change. Such morphological changes were mainly determined by substrate interfacial relaxation, rather than interfacial elasticity. selleck inhibitor Single-cell tracking identified biphasic motility with the minimum speed at intermediate relaxation time (~350 ms), where cells showed transitional morphologies between epithelial and mesenchymal traits. In that relaxation level, partially deformed cells moved around to coalesce with surrounding cells, eventually assembling into compact cellular aggregates. These results highlight, unlike the conventional hanging-drop technique, an appropriate level of interfacial relaxation is critical for efficient cell aggregate maturation on adhesive viscoelastic matrices. This work not only elucidates that the interfacial relaxation as the essential mechanical parameter for epithelial cell adhesion and migration, but also gives useful tips for creating physiologically relevant drug screening platform.
The concurrence of several chronic conditions is a rising concern that poses a serious burden on ageing populations. Analysing how these conditions appear together and how they change through time may provide useful information to design successful multimorbidity-management programs.

To identify multimorbidity patterns and their related characteristics from a longitudinal perspective.

25,931 older adults aged 50+ drawn from the Survey of Health, Ageing and Retirement in Europe (SHARE), a population-based longitudinal European study.

A sex-stratified Latent Transition Analysis was conducted to fit latent classes based on 15 self-reported chronic conditions across three time points. Health-related and socioeconomic variables were assessed as covariates of those patterns.

We identified 4 time-constant latent classes for each sex. A "severely impaired" class (with a weighted prevalence percentage of 7.24% for females and 3.30% for males at the first time point), a "metabolic" class (26.15% and 23.82%) and a "healthy" class (50.92% and 54.32%). The fourth class was named "osteoarticular" for females (15.70%) and "articular-COPD-ulcer" for males (18.56%). Age, smoke, material deprivation and a high body mass index were associated with worse health patterns, whereas education, being employed and physical activity were related to less multimorbid classes. Few class changes were detected when modelling transitions.

We reported information of multimorbidity classes and their characteristics that may help to develop targeted health strategies. Within a time window of four years, the identified latent classes were consistent between time points.

After identifying candidate dimensions, we show how moral judgments can emerge in this space directly from object perception, without any appeal to moral rules or abstract values. Our reductive "minimal model" (Batterman & Rice, 2014) elaborates Beal's (2020) claim that moral cognition is determined, at the most basic level, by "ontological frames" defining subjects, objects, and the proper relation between them. We expand this claim into a set of formal hypotheses that predict moral judgments based on how objects are "framed" in the relevant dimensions of "moral space."
