Preparation and Characterization of a Novel Self-Healing Transparent Polyimide Film Based on Dynamic Disulfide Bonds.

Self-healing optically transparent polyimides have potential applications in optoelectronic device fabrication. In this study, for the first time, we successfully prepared a novel self-healing polyimide film containing reversible disulfide bonds through chemical imidization by introducing cystamine as a self-healing functional monomer into the molecular structure of conventional polyimides. The incorporation of cystamine enabled the films to maintain high transmittance (>87%) and tensile strength (>99 MPa).

Efficacy and safety of wet cupping in the treatment of neurodermatitis: a systematic review and meta-analysis.

Background: Neurodermatitis is a chronic skin condition characterized by intense itching and skin thickening due to neurological dysfunction. Its persistent nature poses a challenge to effective treatment, significantly impacting patients' quality of life. Wet cupping therapy is increasingly being used in clinics to manage neurodermatitis, so it is imperative to assess the evidence regarding its effectiveness and safety.

Background: With the rapidly ageing population, an increasing number of patients with dementia will be cared for in hospitals. Clinical nurses' confidence in dementia care is crucial to provide quality care.

Local therapy combined with anti-PD-1 immunotherapy for advanced lung adenocarcinoma: A case report.

Lung adenocarcinoma (LUAD) encompasses all lung epithelial cancers except small-cell lung cancer. Although programmed cell death protein 1 (PD-1) inhibitors, such as pembrolizumab, and other Food and Drug Administration-approved immune checkpoint inhibitors, offer new hope for LUAD treatment, LUAD's overall efficacy remains limited. Thus, the combination of immunotherapy with other therapeutic approaches has gained widespread attention.

A new therapeutic perspective: Erastin inhibits tumor progression by driving ferroptosis in myelodysplastic syndromes.

Ferroptosis is a recently identified and evolutionarily conserved form of programmed cell death. This process is initiated by an imbalance in iron metabolism, leading to an overload of ferrous ions. These ions promote lipid peroxidation in the cell membrane through the Fenton reaction.

Effects of grape seed procyanidins on the lipid metabolism of growing-finishing pigs based on transcriptomics and metabolomics analyses.

This study investigated how lipid metabolism in the longissimus thoracis is influenced by the diet supplemented with grape seed procyanidins (GSPs) in growing-finishing pigs. Forty-eight crossbred pigs were randomly assigned to four groups, each receiving a basal diet, or basal diet added with 150, 200, and 250 mg/kg GSPs. Transcriptomics and metabolomics were employed to explore differential gene and metabolite regulation.

NEPTUNE is a rare disease network that is focused on patients of all ages with minimal change disease, focal segmental glomerulosclerosis, and membranous nephropathy.

Upregulation of S100A6 and its relation with CD34 cells apoptosis in high-risk myelodysplastic syndromes patients.

Objectives: Myelodysplastic syndromes (MDS) are a group of myeloid malignancies characterized by peripheral blood cytopenia and hematopoietic dysplasia that often progress to acute myeloid leukemia (AML). Increased apoptosis of normal hematopoietic cells and decreased apoptosis of malignant clonal hematopoietic cells in patients with MDS is some of the mechanisms leading to ineffective hematopoietic cells in the bone marrow. S100 calcium-binding protein A6 (S100A6) is upregulated in many malignancies.

Label-free colorimetric detection of tetracycline using gold nanoparticles with different surface charge.

Targeted multi-omic analysis of human skin tissue identifies alterations of conventional and unconventional T cells associated with burn injury.

Burn injuries are a leading cause of unintentional injury, associated with a dysfunctional immune response and an increased risk of infections. Despite this, little is known about the role of T cells in human burn injury. In this study, we compared the activation and function of conventional T cells and unconventional T cell subsets in skin tissue from acute burn (within 7 days from initial injury), late phase burn (beyond 7 days from initial injury), and non-burn patients.

Myeloid-derived suppressor cells inhibit natural killer cells in myelodysplastic syndromes through the TIGIT/CD155 pathway.

Objective: This experiment will explore the role of TIGIT/PVR signaling pathway in the pathogenesis of MDS immune tolerance through in vitro co-culture of NK cells and MDSC cells.

Methods: Flow cytometry was used to detect the expression percentage of MDSCs and CD155 on MDSCs in the bone marrow of MDS patients and controls. The expression of NK cell surface receptors (NKG2D, NKp30, NKp46), secreted cytokines (perforin, granzyme B, CD107a, IFN-γ) and NK cell apoptosis rate were detected by flow cytometry to evaluate the effect of MDSCs on NK cell function.

Au Nanoparticles (NPs) Decorated Co Doped ZnO Semiconductor (Co-ZnO/Au) Nanocomposites for Novel SERS Substrates.

Au nanoparticles were decorated on the surface of Co-doped ZnO with a certain ratio of Co/Co to obtain a novel semiconductor-metal composite. The optimal substrate, designated as Co-ZnO/Au, is beneficial to the promotion of separation efficiency of electron and hole in a semiconductor excited under visible laser exposure, which the enhances localized surface plasmon resonance (LSPR) of the Au nanoparticles. As an interesting finding, during Co doping, quantum dots of ZnO are generated, which strengthen the strong semiconductor metal interaction (SSSMI) effect.
