Article Abstract
Purpose: To evaluate the prognostic value of preoperative plasma osteopontin (OPN) levels in patients with early stage of hepatocellular carcinoma (HCC).
Methods: Preoperative plasma levels of OPN were detected by ELISA in 68 patients with tumor-node metastasis system stage-I of HBV-related HCC, and their association with tumor recurrence or patients' survival was analyzed.
Results: The median plasma OPN level of patients was 82.51 ng/ml (25–75% interquartile range, 63.15–110.45 ng/ml). Plasma OPN levels in patients with tumor size C5 cm in diameter were significantly higher than that of patients with tumor size\5 cm in diameter (104.76 vs.75.16 ng/ml, P = 0.003). When the 100 ng/ml was used asa cut-off value to divide the patients into two groups: the higher plasma OPN group and the lower plasma OPN group, the tumor recurrence rate of the higher plasma OPN group was significantly higher than that of the lower plasma OPN group (52.17 vs. 24.44%, P = 0.022). Meanwhile, the recurrence rate of the patients with positive alpha fetoprotein (AFP) (45.5%) was significantly higher than that of those negative AFP patients (12.5%,P = 0.006). A higher plasma OPN level was one leading independent prognostic factor for both overall survival(OS) and relapse-free survival in multivariate Cox models.
Conclusion: The preoperative plasma OPN level and serum AFP level in patients with early stage of HCC can be used as a prognostic marker for early stage of HCC.

Plasma nitriding is one of the surface modifications that show more effectiveness than other methods. In this study, the plasma-based ion implantation (PBII) technique was performed on the surface of titanium alloy (Ti-6Al-4V, Ti64) using a mixture of nitrogen (N) and argon (Ar), resulting in a plasma-nitrided surface (TiN-Ti64). The surface composition of the TiN-Ti64 was verified through X-ray photoelectron spectroscopy (XPS).

The BALB/c model of pristane-induced lupus (PIL) exhibits cognitive impairment features resembling neuropsychiatric lupus (NPLSE). Osteopontin (OPN) is associated with disease activity in SLE; however, its involvement in NPLSE is not yet entirely determined. Our study aims to elucidate the contribution of full-length OPN (OPN-FL) plasma expression, OPN N-half, and to cognitive impairment in the PIL mice model.

Context: The mechanisms underlying bone fragility and increased fracture risk observed in individuals with type 2 diabetes (T2D) are not yet fully elucidated. Previous research has suggested a role for neuropeptides in regulating bone metabolism; however, the contribution of the neuropeptide Neurotensin (NT), which is thoroughly implicated in T2D and cardiovascular disease, has not been investigated in this context.
Objective: To study the relationship between circulating levels of the NT precursor proneurotensin (proNT) and bone mineralisation in T2D women.
Temporal changes in biomarker levels and their association with the early degeneration stage of transcatheter aortic valves in F-fluorodeoxyglucose and F-sodium fluoride positron emission tomography studies.

Introduction: As transcatheter aortic valve implantation (TAVI) indications expand, understanding the valve degeneration process and potential influencing biomarkers becomes increasingly important.
Aim: To investigate temporal changes in biomarker levels and their potential association with F-fluorodeoxyglucose (F-FDG) and F-sodium fluoride (F-NaF) uptake, assessed using positron emission tomography/computed tomography (PET/CT) studies as markers for native aortic annulus calcifications and early-stage TAVI valve degeneration.
Material And Methods: A total of 71 TAVI patients underwent blood sampling and transthoracic echocardiography at baseline (pre-TAVI) and 6, 12, 18, and 24 months after the procedure.
Osteopontin Promotes Cholangiocyte Secretion of Chemokines to Support Macrophage Recruitment and Fibrosis in MASH.

Background And Aims: Osteopontin (OPN) promotes the ductular reaction and is a major driver of chronic liver disease (CLD) progression. Although CLD is characterised by the accumulation of inflammatory cells including macrophages around the peri-portal regions, the influence of OPN on recruitment is unclear. We investigated the role of OPN in cholangiocyte chemokine production and macrophage recruitment by combining in vivo, in vitro, and in silico approaches.
