Diffuse parenchymal bleeding and major air leaks still present a challenge to the thoracic surgeon. This study was therefore designed to evaluate efficacy and handling of fibrin-glue-coated collagen fleece, to address these problems. In an experimental part defects were produced in lungs of troll pigs to compare the use of the fleece with infrared coagulation. Immediate airtightness and postoperative adhesions were evaluated. Scores were designed to evaluate quality and extension of the adhesions. In a clinical study parenchymal resection sites were sealed with fibrin-glue-coated collagen fleece in 52 patients. No patient suffered from postoperative bleeding. In three cases air leaks were still present on the third postoperative day, representing a 5.8% failure rate. 92.3% of the patients showed neither postoperative hemorrhage nor prolonged air leaks. A fixed combination of collagen fleece and fibrin glue consequently can be considered as a valuable tool in thoracic surgery.

Background: Colorectal cancer (CRC) has high incidence and mortality rates, with severe prognoses during invasion and metastasis stages. Despite advancements in diagnostic and therapeutic technologies, the impact of the tumour microenvironment, particularly extracellular matrix (ECM) stiffness, on CRC progression and metastasis is not fully understood.
Methods: This study included 107 CRC patients.

Hypertrophic scar (HS) is a common fibroproliferative disorders with no fully effective treatments. The conversion of fibroblasts to myofibroblasts is known to play a critical role in HS formation, making it essential to identify molecules that promote myofibroblast dedifferentiation and to elucidate their underlying mechanisms. In this study, we used comparative transcriptomics and single-cell sequencing to identify key molecules and pathways that mediate fibrosis and myofibroblast transdifferentiation.

Early diagnosis is critical for providing a timely window for effective therapy in pulmonary fibrosis (PF); however, achieving this remains a significant challenge. The distinct honeycombing patterns observed in computed tomography (CT) for the primary diagnosis of PF are typically only visible in patients with moderate to severe disease, often leading to missed opportunities for early intervention. In this study, we developed a nanoprobe designed to accumulate at fibroblastic foci and loaded with the CT sensitizer iodide to enable effective early diagnosis of PF.

Introduction: Bone marrow-derived mesenchymal stem cell-derived extracellular vesicles (BMSC-EVs) are widely used for therapeutic purposes in preclinical studies. However, their utility in treating diabetes-associated atherosclerosis remains largely unexplored. Here, we aimed to characterize BMSC-EV-mediated regulation of autophagy and macrophage polarization.

Cardiovascular disease is one of the foremost causes of morbidity and mortality worldwide, with low-density lipoprotein cholesterol (LDL-C) identified as a significant risk factor for subsequent ischemic events. Elevated LDL-C contributes to vascular injury and fibrosis by upregulating the expression of connective tissue growth factor and collagen IV, which leads to endothelial cell dysfunction that initiates the process of atherosclerotic diseases. Currently, there is an absence of clear, risk-defined criteria to identify patients who are in greater needs for intensive LDL-C reduction, particularly with PCSK9 inhibitors.
