Background: Hepatocyte growth factor (HGF), a member of the endothelial-specific growth factors with the greatest mitogenic activity, may play a role in the protection and/or repair of vascular endothelial cells injured by atherosclerosis. As a result, plasma HGF concentration may increase in response to endothelial cell damage. To test this hypothesis, we measured plasma concentrations of HGF in patients with or without aorto-iliac artery atherosclerotic disease.
Methods: One hundred ten consecutive patients who underwent coronary angiography were enrolled in this study. Abdominal aortography was performed after coronary arteriography to determine whether aorto-iliac artery atherosclerotic disease was present. Peripheral venous blood samples were obtained to measure the plasma HGF concentration.
Results: Aortography revealed aorto-iliac atherosclerotic disease in 35 patients (32%). The plasma HGF concentration was significantly higher in patients with arteriosclerotic lesions (0.35 +/- 0.11 ng/mL) than in patients without atherosclerotic lesions (0.27 +/- 0.09 ng/mL, P =.0002). On the basis of multiple logistic regression analysis of the relationships between coronary risk factors, age, sex, severity of coronary artery disease, plasma HGF concentration, and the presence of arteriosclerotic lesions, plasma HGF concentration (P =.0005) and age (P =.035) were found to predict independently the presence of aorto-iliac arteriosclerosis.
Conclusion: Plasma HGF concentration can be used to predict the presence of arteriosclerotic lesions in the region from the abdominal aorta to the femoral arteries.

Introduction: The purpose of this study was to compare the growth factor concentrations in undiluted autologous platelet-rich plasma (APRP) and autologous serum (AS) eye drops.
Methods: This was a single-center, prospective trial conducted in a tertiary university hospital in Bangkok, Thailand. Ninety-six patients with moderate-to-severe dry eye disease, who were randomly assigned to receive either 100% APRP or 100% AS, were enrolled in the study.

Due to its antimicrobial, anti-inflammatory and pro-healing properties, the application of cold atmospheric plasma (CAP) has emerged as a new and promising therapeutic strategy in various fields of medicine, including general medicine and dentistry. In this light, the aim of the present study was to investigate the effects of a homemade plasma jet on the cellular behaviour of two important cell types involved in gingivitis, namely gingival fibroblasts (HGF-1 cell line) and macrophages (RAW 264.7 cell line), by the direct application of CAP in different experimental conditions.

Background: Emerging evidence underscores a bidirectional relationship between ischemic stroke (IS) and inflammation, yet the causality of this association remains uncertain. We conducted a two-sample bidirectional Mendelian randomization (MR) study aimed at investigating the causal links between inflammation and IS.
Methods: Single nucleotide polymorphism from genome-wide association studies of 112 inflammatory cytokines and IS were chosen as instrumental variables.

Background: The presence of low-grade inflammation has been reported in people with type 2 diabetes and related to the development of (macro)vascular complications. Whether systemic inflammation is present in type 1 diabetes and linked to long-term complications remains unknown. We used a targeted proteomics approach to compare inflammation in people with type 1 diabetes and type 2 diabetes with control subjects and linked these proteins to diabetes related characteristics and complications.
