Background: Both dynamic and static progressive (turnbuckle) splints are used to help stretch a contracted elbow capsule to regain motion after elbow trauma. There are advocates of each method, but no comparative data. This prospective randomized controlled trial tested the null hypothesis that there is no difference in improvement of motion and Disabilities of the Arm, Shoulder and Hand (DASH) scores between static progressive and dynamic splinting.
Methods: Sixty-six patients with posttraumatic elbow stiffness were enrolled in a prospective randomized trial: thirty-five in the static progressive and thirty-one in the dynamic cohort. Elbow function was measured at enrollment and at three, six, and twelve months later. Patients completed the DASH questionnaire at enrollment and at the six and twelve-month evaluation. Three patients asked to be switched to static progressive splinting. The analysis was done according to intention-to-treat principles and with use of mean imputation for missing data.
Results: There were no significant differences in flexion arc at any time point. Improvement in the arc of flexion (dynamic versus static) averaged 29° versus 28° at three months (p = 0.87), 40° versus 39° at six months (p = 0.72), and 47° versus 49° at twelve months after splinting was initiated (p = 0.71). The average DASH score (dynamic versus static) was 50 versus 45 points at enrollment (p = 0.52), 32 versus 25 points at six months (p < 0.05), and 28 versus 26 points at twelve months after enrollment (p = 0.61).
Conclusions: Posttraumatic elbow stiffness can improve with exercises and dynamic or static splinting over a period of six to twelve months, and patience is warranted. There were no significant differences in improvement in motion between static progressive and dynamic splinting protocols, and the choice of splinting method can be determined by the patients and their physicians.

Time-dependent afterglow colored (TDAC) behavior differs from static afterglow by involving wavelength changes, enabling low-cost, high-level encryption and anti-counterfeiting. However, the existing carbon dot (CD)-based TDAC materials lack a clear mechanistic explanation and controllable wavelength changes, significantly hindering the progress of practical applications in this field. In this study, we synthesized CDs composites with customizable tunable TDAC wavelengths across the visible region.

Chronic obstructive pulmonary disease (COPD) is the third leading cause of death worldwide and the progressive nature heightens the calamity of the disease. Despite countless existing COPD studies, lung mechanics are often reported under positive-pressure ventilation (PPV) and implications and extrapolations made from these studies pose serious restrictions as recent works have divulged disparate elastic and energetic results between PPV and more physiological negative-pressure counterparts (NPV). This non-equivalence of PPV and NPV needs to be investigated under diseased states to augment our understanding of disease mechanics.

As the core of leaf functional traits, the trade-off relationship between the petiole and lamina expresses the plant's adaptability to the environment in terms of support structure and photosynthesis. We investigated the proportions of allometric growth in the relationship between the petiole and the lamina of broadleaf woody plants in temperate highland Tianshan Mountains montane forests through three dimensions (length, area, and mass), including the length of the lamina (LL) and the length of the petiole (PL), and the area of the lamina (LA) and petiole cross sectional area (PCA) versus the mass of the lamina (LM) and the mass of the petiole (PM), as well as exploring the characteristics of the variance in response to seasonal changes. We found that the functional traits in all three dimensions showed a clear convergent evolution as the seasons progressed, that is, a "seasonal effect" of increasing and then decreasing.

Dynamic modeling of cellular states has emerged as a pivotal approach for understanding complex biological processes such as cell differentiation, disease progression, and tissue development. This review provides a comprehensive overview of current approaches for modeling cellular state dynamics, focusing on techniques ranging from dynamic or static biomolecular network models to deep learning models. We highlight how these approaches integrated with various omics data such as transcriptomics, and single-cell RNA sequencing could be used to capture and predict cellular behavior and transitions.
