Background: New biological markers with predictive or prognostic value are highly warranted in the treatment of ovarian cancer. The platelet-derived growth factor (PDGF) system and fibroblast growth factor (FGF) system are important components in tumor growth and angiogenesis.
Materials And Methods: Pre-surgery peripheral blood samples were collected consecutively from 213 patients (42 with normal ovaries, 54 with benign, 21 with borderline, and 96 with malignant ovarian tumors) undergoing surgery for an untreated pelvic mass. Serum PDGF-AA, PDGF-BB, and FGF2 were quantified on a Luminex analyzer.
Results: Median PDGF-AA, PDGF-BB, and FGF2 levels were higher in patients with ovarian cancer than in those with borderline tumors, and normal ovaries, and PDGF-BB and FGF2 were also higher as compared to patients with benign tumors. PDGF-AA and PDGF-BB were associated with FIGO stage and residual tumor and PDGF-BB was associated with histological subtype.
Conclusion: PDGF-AA, PDGF-BB, and FGF2 are up-regulated in ovarian cancer and levels of serum PDGF-AA and PDGF-BB seem to be associated with stage and residual tumor in ovarian cancer.

Background: Multiple sclerosis (MS) is a chronic autoimmune disease damaging the central nervous system. Diminished inflammatory disease activity (DA) as people with MS (pwMS) age motivated randomized clinical trials assessing disease-modifying therapy (DMT) discontinuation in older pwMS given the concern for risks outweighing benefits. This study aims to examine whether peripheral production of Myelin Basic Protein (MBP)-driven cytokine responses mediate the aging-associated decline in MS inflammatory DA.

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.

Article Synopsis
- The study aimed to differentiate between unipolar and bipolar depression by analyzing biological markers PDGF-AA, PDGF-BB, and BDNF using machine learning.
- It included 79 patients and utilized clinical assessments along with blood serum analysis to measure growth factor concentrations.
- Findings indicated significant differences in growth factor levels between the two types of depression, suggesting the potential use of these markers as prognostic tools for diagnosis.

Cartilage injury is common in orthopedics and cartilage tissue engineering provides a therapeutic direction for cartilage regeneration. Albumin (ALB)-platelet-rich fibrin (PRF) is speculated to be an ideal natural scaffold material for cartilage tissue engineering theoretically as a product derived from human venous blood. Through and experiments, it was demonstrated that ALB-PRF displayed porous structure and slowly released growth factors (TGF-β1, PDGF-AA, PDGF-AB, PDGF-BB, EGF, IGF-1 and VEGF), ALB-PRF conditioned media promoted proliferation, migration, adhesion, phenotype maintenance and extracellular matrix secretion of rabbit chondrocytes.

Background: Biomarker analyses are an integral part of cancer research. Despite the intense efforts to identify and characterize biomarkers in patients with cancer, little is known regarding the natural variation of biomarkers in healthy populations. Here we conducted a clinical study to evaluate the natural variability of biomarkers over time in healthy participants.
