Background: It is unclear if there are significant changes in clinical and radiographic outcomes between 1 and 2 years postoperatively after total shoulder arthroplasty (TSA). The current multi-center study sought to compare patient-reported outcome measures (PROMs), range of motion (ROM) and radiographic analysis of glenoid and humeral loosening between one and two-years postoperatively in a cohort of patients after primary anatomic TSA (aTSA).
Methods: A retrospective cohort of patients who underwent primary anatomic TSA between 2017 and 2018 at two high-volume shoulder arthroplasty centers and had baseline, one and two-year PROMs were included in the study.
Addressing the challenge of eliminating bacteria and stimulating osteogenesis in infectious bone defects, where cells and bacteria coexist within the microenvironment, presents a significant hurdle. In this study, a strategy of targeting bacteria is proposed to address this challenge. For this purpose, a methacrylated gelatin composite hydrogel containing zinc ion and D-type cysteine-modified polydopamine nanoparticles (PZC) is developed.

Despite these promising effects, the underlying mechanisms of 5-HMF's action remain elusive, thereby impeding its broader clinical application and development.
Objective: To investigate the impact of 5-HMF on the progression of OA and elucidate its underlying mechanisms.
Background: Given the ubiquity of stress, a key focus of stress research is exploring how to better coexist with stress.
Objective: This study conducted text analysis on stress-related Weibo posts using a web crawler to investigate whether these posts contained positive emotions, as well as elements of mental time travel and meaning-making. A mediation model of mental time travel, meaning-making, and positive emotions was constructed to examine whether meaning-making triggered by mental time travel can foster positive emotions under stress.

Stem cell implantation holds promise for enhancing bone repair, but risks of pathogen transmission and malignant cell transformation should not be ignored. Compared to stem cell implantation, recruitment of endogenous stem cells to injured sites is more critical for in situ bone regeneration. In this study, based on the acidic microenvironment of bone injury, an HG-AA-SDF-1α composite hydrogel with a dual-control intelligent switch function is developed by incorporating stromal cell-derived factor (SDF-1α), arginine carbon dots (Arg-CDs), and calcium ions (Ca) into the oxidized hyaluronic acid/gelatin methacryloyl (HG) hydrogel.

The melatonin carbon dots (MCDs) possess antibacterial and osteogenesis abilities, greatly simplifying the composition of a multifunctional material. Therefore, a multifunctional hydrogel containing MCDs (GH-MCD) is developed to meet the multi-stage and complex repair needs of infectious bone injury in this study.

Methods: Sixty 8-week-old female mice were used, which underwent APOE and ovariectomy procedures, followed by oral administration of Actein (15 mg/kg) and Atorvastatin Calcium (AC, 3 mg/kg) for eight weeks. Body weight, uterine weight, and systemic indexes related to bone metabolism and lipid metabolism were assessed in each group.
Aims: Rotator cuff tear (RCT) is the leading cause of shoulder pain, primarily associated with age-related tendon degeneration. This study aimed to elucidate the potential differential gene expressions in tendons across different age groups, and to investigate their roles in tendon degeneration.
Methods: Linear regression and differential expression (DE) analyses were performed on two transcriptome profiling datasets of torn supraspinatus tendons to identify age-related genes.
Background: A pivotal determinant for the success of tissue regeneration lies in the establishment of sufficient vasculature. Utilizing autologous tissue grafts from donors offers the dual advantage of mitigating the risk of disease transmission and circumventing the necessity for post-transplant immunosuppression, rendering it an exemplary vascularization strategy. Among the various potential autologous donors, adipose tissue emerges as a particularly auspicious source, being both widely available and compositionally rich.

Temporomandibular joint (TMJ) cartilage repair poses a considerable clinical challenge, and tissue engineering has emerged as a promising solution. In this study, we developed an injectable reactive oxygen species (ROS)-responsive multifunctional hydrogel (RDGel) to encapsulate dental pulp stem cells (DPSCs/RDGel in short) for the targeted repair of condylar cartilage defect. The DPSCs/RDGel composite exhibited a synergistic effect in the elimination of TMJ OA (osteoarthritis) inflammation via the interaction between the hydrogel component and the DPSCs.

To investigate the occurrence and spatiotemporal distributions of ABGs, a total of one hundred and eighteen urban dust samples were collected from different districts of Xiamen city, China in summer and winter. Although inorganic arsenic species, including arsenate [As(V)] and arsenite [As(III)], were found to be predominant, the methylated arsenicals, particularly trimethylarsine oxide [TMAs(V)O] and dimethylarsenate [DMAs(V)], were detected in urban dust.
