Novel multiple Z-score models for detection of coronary artery dilation: application in Kawasaki disease.

Background: This study aims to develop Z-Score models to normalize measurements of three coronary arteries and enhance the diagnosis of Kawasaki disease (KD) in children from newborns to 10 years old. Developing a reliable Z-Score model is challenging, as some existing models fail the normality test. Overcoming these challenges is crucial for improving KD diagnosis.

Role of periodontal ligament fibroblasts in periodontitis: pathological mechanisms and therapeutic potential.

Periodontal ligament fibroblasts (PDLFs) play a crucial role in the etiology of periodontitis and periodontal tissue regeneration. In healthy periodontal tissues, PDLFs maintain the homeostasis of periodontal soft and hard tissues as well as the local immune microenvironment. PDLFs also have the potential for multidirectional transdifferentiation and are involved in periodontal tissue regeneration.

Epidermal growth factor receptor ligands enriched in follicular fluid exosomes promote oncogenesis of fallopian tube epithelial cells.

Background: Incessant ovulation is the main etiologic factor of ovarian high-grade serous carcinomas (HGSC), which mostly originate from the fallopian tube epithelium (FTE). Receptor tyrosine kinase (RTK) ligands essential for follicle development and ovulation wound repair were abundant in the follicular fluid (FF) and promoted the transformation of FTE cells. This study determined whether RTK ligands are present in FF exosomes and whether epidermal growth factor receptor (EGFR) signaling is essential for oncogenic activity.

Lenvatinib and immune-checkpoint inhibitors in hepatocellular carcinoma: mechanistic insights, clinical efficacy, and future perspectives.

Lenvatinib is a multi-target tyrosine kinase inhibitor widely used in the treatment of hepatocellular carcinoma (HCC). Its primary mechanism of action involves inhibiting signal pathways such as vascular endothelial growth factor receptors (VEGFR) and fibroblast growth factor receptors (FGFR), thereby reducing tumor cell proliferation and angiogenesis and affecting the tumor's immune microenvironment. In the treatment of liver cancer, although lenvatinib monotherapy has shown good clinical effect, the problem of drug resistance is becoming more and more serious.

Vocal Fold Vibration Associated With Inspiratory Phonation-An Acoustic and Electroglottographic Study.

Objective: Different from normal or expiratory phonation (EP), inspiratory phonation (IP) involves the use of an ingressive airflow and it is frequently used in clinical voice assessment and treatment. The present study examined the voice quality and glottal vibratory characteristics associated with IP through acoustic (AC) and electroglottographic (EGG) analyses.

Methods: The AC and EGG signals of the vowel /i/ produced by 43 young, vocally healthy adults using IP and EP were simultaneously recorded and analyzed using Praat.
