Mixed human umbilical cord-derived mesenchymal stem cells (UC-MSCs) are widely applied in clinical trials to treat various diseases due to their multipotent differentiation potential and immune regulatory activities. However, the lack of a clear understanding of their heterogeneity hampers their application to precisely treat diseases. Moreover, few studies have experimentally authenticated the functions of so-called UC-MSC subpopulations classified from scRNA-seq samples. Here, this work draws a large-scale single-cell transcriptomic atlas and identified three clusters (C1, C2, and C3), representing the primed, intermediate, and stem statuses individually. The C1 and C3 clusters feature higher expression of cytokines and stemness markers, respectively. Surprisingly, further experimental assays reveal that the BAMBIhigh MFGE8high C1 subgroup has a unique phenotype, distinct transcriptomic profile, and limited adipogenic differentiation potential but compromised immunosuppressive activity in vitro and in vivo in lupus mice. Thus, this work is helpful to clarify the nature of human UC-MSCs and to choose optimal MSC types to treat specific diseases in the future.With the emerging of the Internet of Things, chemiresistive gas sensors have been extensively applied in industrial production, food safety, medical diagnosis, and environment detection, etc. Considerable efforts have been devoted to improving the gas-sensing performance through tailoring the structure, functions, defects and electrical conductivity of sensitive materials. Among the numerous sensitive materials, mesoporous semiconductor metal oxides possess unparalleled properties, including tunable pore size, high specific surface area, abundant metal-oxygen bonds, and rapid mass transfer/diffusion behavior (Knudsen diffusion), which have been regarded as the most potential sensitive materials. Herein, the synthesis strategies for mesoporous metal oxides are overviewed, the classical functionalization techniques of sensitive materials are also systemically summarized as a highlight, including construction of mesoporous structure, regulation of micro-nano structure (i.e., heterojunctions), noble metal sensitization (e.g., Au, Pt, Ag, Pd) and heteroatomic doping (e.g., C, N, Si, S). In addition, the structure-function relationship of sensitive materials has been discussed at molecular-atomic level, especially for the chemical sensitization effect, elucidating the interface adsorption/catalytic mechanism. Moreover, the challenges and perspectives are proposed, which will open a new door for the development of intelligent gas sensor in various applications.Following injury, skeletal muscle regenerates but fatty tissue accumulation is seen in aged muscle or muscular dystrophies. Fibro/adipogenic progenitors (FAPs) are key players in these events; however, the effect of primary cilia on FAPs remains unclear. Here, it is reported that genetic ablation of trichoplein (TCHP), a ciliary regulator, induces ciliary elongation on FAPs after injury, which promotes muscle regeneration while inhibiting adipogenesis. The defective adipogenic differentiation of FAPs is attributed to dysfunction of cilia-dependent lipid raft dynamics, which is critical for insulin/Akt signaling. It is also found that interleukin (IL) 13 is substantially produced by intramuscular FAPs, which are upregulated by ciliary elongation and contribute to regeneration. Mechanistically, upon injury, long cilia excessively activate the IL33/ST2/JNK axis to enhance IL13 production, facilitating myoblast proliferation and M2 macrophage polarization. The results indicate that FAPs organize the regenerative responses to skeletal muscle injury via cilia-mediated insulin/Akt and ST2/JNK signaling pathways.The chemical examination of the rice solid fermentation products of the deep-sea-derived fungus Aspergillus puniceus A2 resulted in the isolation of one new sesquiterpenoid malfilanol C (1), together with a rare analogue malfilanol B (2). The planar structure of 1 was resolved on the basis of the extensive analyses of the spectroscopic data (HRESIMS and NMR spectra), and its absolute configuration was assigned by quantum chemical calculation of the ECD data. Compound 1, featuring a bicyclo[5.4.0]-undecane nucleus skeleton, was the third example of this subclass sesquiterpenoids found from nature. Additionally, the subclass sesquiterpenoids 1 and 2 were discovered from marine-derived-fungi for the first time. All the isolated metabolites were evaluated the antibacterial activities against Staphylococcus aureus ATCC 29213 and Escherichia coli ATCC 25922. Compound 1 exhibited weak antibacterial activity against S. buy Adenine sulfate aureus ATCC 29213.The COVID-19 pandemic disproportionately impacted uninsured and minority populations, contributing to and reinforcing long-lasting health inequities. Clínica Esperanza/Hope Clinic (CEHC), a free clinic serving uninsured individuals, is one 'safety-net' clinic that improved access to COVID-19 testing and vaccinations for an at-risk population during the pandemic. A retrospective review was performed to quantify COVID-19 testing and vaccination rates for clinic participants, which were compared to rates in the general population. 51.7% of patients seeking COVID-related care at CEHC were uninsured, compared to 8% in Providence and 4.8% in Rhode Island. CEHC performed 5,623 COVID-19 tests for 4,498 unique individuals, a total of 15,783 vaccines were administered, and 10 to 20% of COVID-care participants reported food insecurity during the study period. The prevalence of COVID-19 in the uninsured population and the high demand for vaccines highlight the important role that free clinics can play in the pandemic setting.Nucleic acid (NA) computation has been widely developed in the past years to solve kinds of logic and mathematic issues in both information technologies and biomedical analysis. However, the difficulty to integrate non-NA molecules limits its power as a universal platform for molecular computation. Here, we report a versatile prototype of hybridized computation integrated with both nucleic acids and non-NA molecules. Employing the conformationally controlled ligand converters, we demonstrate that non-NA molecules, including both small molecules and proteins, can be computed as nucleic acid strands to construct the circuitry with increased complexity and scalability, and can be even programmed to solve arithmetical calculations within the computational nucleic acid system. This study opens a new door for molecular computation in which all-NA circuits can be expanded with integration of various ligands, and meanwhile, ligands can be precisely programmed by the nuclei acid computation.Central nervous system is sensitive and vulnerable to heat. Oxidative state and oxidative damage of neurons under heat stress are vital for understanding early consequences and mechanisms of heat-related neuronal injury, which remains elusive partly due to the technical challenge of in situ and quantitative monitoring methods. Herein, a temperature-controlled scanning electrochemical microscopy (SECM) platform with programmable pulse potential and depth scan modes is developed for in situ and quantitatively monitoring of oxygen consumption, extracellular hydrogen peroxide level, and cell membrane permeability of neurons under thermal microenvironment of 37-42 °C. The SECM results show that neuronal oxygen consumption reaches a maximum at 40 °C and then decreases, extracellular H2 O2 level increases from 39 °C, and membrane permeability increases from 2.0 ± 0.6 × 10-5 to 7.2 ± 0.8 × 10-5 m s-1 from 39 to 42 °C. The therapeutic effect on oxidative damage of neurons under hyperthermia conditions (40-42 °C) is further evaluated by SECM and fluorescence methods, which can be partially alleviated by the potent antioxidant edaravone. This work realizes in situ and quantitatively observing the heat-induced oxidative state and oxidative damage of living neurons using SECM for the first time, which results can contribute to a better understanding of the heat-related cellular injury mechanism.The analysis of the statistics of random walks undertaken by passive particles in complex media has important implications in a number of areas including pathogen transport and drug delivery. In several systems in which heterogeneity is important, the distribution of particle step-sizes has been found to be exponential in nature, as opposed to the Gaussian distribution associated with Brownian motion. Here, we first develop a theoretical framework to study a simplified version of this problem the motion of passive tracers in a range of sub-environments with different viscosity. We show that in the limit of a large number of equi-distributed sub-environments spanning a broad viscosity range, an exact analytical expression for the underlying particle step-size distribution can be derived, which approaches an exponential distribution when step sizes are small. We then validate this using a simple experimental system of glycerol-water mixtures, in which the volume fraction of glycerol is systematically varied. Overall, the assumption of exponentially distributed step sizes may substantially over-estimate the incidence of large steps in heterogeneous systems, with important implications in the analysis of various biophysical processes.Research examining the prevalence and impacts of stalking on mental health professionals (MHPs) has grown over the last two decades. Yet only one previous review has been undertaken examining impacts on staff and focusing on clients as stalkers, with prevalence estimated between 10% and 13%. This systematic review sought to assess prevalence of stalking, and associated impacts and methods of coping reported by MHPs, irrespective of perpetrator type. The search included all healthcare professional groups working in a mental health setting, reported in English or with available translation. Secondary searches were conducted through references cited in primary papers. Of the 7,060 papers identified in five databases, 11 peer-reviewed papers met rigorous inclusion criteria and were quality appraised. Reviewed studies reported prevalence rates between 10.2% and 50%, with higher quality papers reporting a narrower band, 13.9% and 14.3%. However, substantial variability in stalking definitions, and quality of methodology precluded precise prevalence estimation. Participants within the included studies disclosed significant adverse impacts on confidence and competence at work as a consequence of their experiences. Staff invoked substantial workplace and lifestyle changes to mitigate impacts of stalking. However, studies revealed staff disclosed stalking by perpetrators other than clients, notably colleagues and intimate partners, as often or more frequently than by clients. Limitations of the included research and future directions are discussed.Kawasaki disease (KD) is an acute vasculitis of early childhood with unknown cause, which can be complicated by coronary artery lesions resulting in thrombosis. Fu and coworkers identify thymic stromal lymphopoietin (TSLP) to be increased in KD patients with thrombosis. They demonstrate that TSLP can activate platelets, induce mitophagy and trigger thrombus formation in vitro, suggesting that TSLP may have potential as a therapeutic target against KD-associated thrombosis. Commentary on Fu L, et al. TSLP induces platelet mitophagy and promotes thrombosis in Kawasaki disease.
