Applied Mandibular Osteometry in Young Lambs: Morphometric and Clinical Insights.

Anat Histol Embryol

January 2025

Laboratório de Design Anatômico/LabDA-Departamento de Morfologia, Universidade Federal de Santa Maria, Santa Maria, Rio Grande do Sul, Brazil.

Osteometric studies of the mandible are useful for identifying polymorphisms that are affected by general factors of anatomical variation, such as breed and gender, but age-related changes have not yet been reported in sheep. Our results showed that the morphometric parameters of the mandible were significantly affected by the age of the lambs. However, at 155 days of age, the mandible already presents all the morphological characteristics observed in adult animals.

Background: Non-human primates (NPHs), such as rhesus macaques, cynomolgus monkeys, and Assamese macaques, play a crucial role in biomedical research. However, baseline cytokine and electrolyte data for these three species, particularly data stratified by age and sex, are limited. Therefore, the aim of this study was to establish and analyze age- and sex-specific cytokine and electrolyte profiles in these three species.

Purpose: Previous studies have reported divergent sexual responses to aging; however, specific variations in gene expression between aging males and females and their potential association with age-related retinal diseases remain unclear. This study collected data from public databases and developed a comprehensive comparison of retina between aging females and males.

Methods: Single-cell RNA (scRNA) and bulk RNA sequencing data of the aging retina from females and males in public databases were utilized for integrated analysis to investigate sex-biased expression in retina.

Anatomic-Based Diagnosis and Filler Injection Techniques: Chin Augmentation and Jawline Contouring.

J Craniofac Surg

January 2025

Department of Oral Biology, Division in Anatomy and Developmental Biology, Human Identification Research Institute, BK21 FOUR Project, Yonsei University College of Dentistry.

Chin augmentation and jawline contouring have emerged as significant procedures in aesthetic medicine, addressing both structural and age-related changes in the lower face. This review explores anatomic-based diagnosis and filler injection techniques for these treatments. Ethnic variations in facial structure necessitate different approaches, with Western patients often seeking jawline definition, while Asian patients frequently require chin projection.

Background: Ventricular tachycardia ablation (VTA) is an important treatment option for ventricular tachycardia, with increasing use across all age groups. However, age-related differences in outcomes remain a concern.

Objective: This study aimed to investigate age-related trends in VTA procedures and their associated adverse events across the United States from 2011 to 2021.
