RNA-sequencing demonstrates transcriptional differences between human vocal fold fibroblasts and myofibroblasts
Published 2025-04-01“…Results Utilizing bulk RNA sequencing technology, we identified differentially expressed genes between four cell lines of normal fibroblasts (cVFF), one line of scarred fibroblasts (sVFF), and four lines of fibroblasts treated with transforming growth factor-beta 1 (TGF-β1), representing an induced-scar phenotype (tVFF). Principal component analysis revealed clustering of normal fibroblasts separate from the clustering of fibroblasts treated with TGF-β1; scarred fibroblasts were more similar to normal fibroblasts than fibroblasts treated with TGF-β1. …”

Two Machine-learning Hybrid Models for Predicting Type 2 Diabetes Mellitus
Published 2025-04-01“…The main contribution of this study is the proposal of two hybrid models for diabetes diagnosis in two scenarios: (1) Scenario 1 (presence of outlier data): Hybrid Model 1 combines the K-medoids clustering algorithm with a Gaussian naive Bayes (GNB) classifier based on kernel density estimation (KDE) to handle outliers and (2) Scenario 2 (after removing outlier data): Hybrid Model 2 combines the K-means clustering algorithm with a GNB classifier based on KDE with suitable bandwidth. We performed principal component analysis to minimize dimensionality and evaluated the models using fivefold cross-validation. …”
