Objectives: We analyzed different methods used to process autologous fat tissues for vocal fold injection (VFI). VFI is a safe procedure that preserves the folds' original elasticity and vibration properties and rarely triggers foreign-body reactions, but is often a temporary treatment due to fat reabsorption. To avoid it, selecting a technique that provides as many viable implantable adipocytes as possible is mandatory.
Study Design: This is a systematic review.
Methods: Data were collected from PubMed, Embase, Ovid, and Cochrane Library. Authors systematically reviewed databases for papers on autologous fat tissue processing methods involving human injections in vocal folds and vocalization outcomes that evolved the acoustic analysis of the voice before and after the surgical procedure, independently of the follow-up time.
Results: Nine out of the 517 articles met selection criteria for analysis. No standardized technique was found.
Conclusion: There is no standardized technique for processing fat tissue for vocal fold injection. Further research is needed to point out the best available technique.

The prevalence of metabolic dysfunction-associated steatotic liver disease (MASLD), which is increasingly being recognized as a leading cause of chronic liver pathology globally, is increasing. The pathophysiological underpinnings of its progression, which is currently under active investigation, involve oxidative stress. Human adipose tissue, an integral endocrine organ, secretes an array of adipokines that are modulated by dietary patterns and lifestyle choices.

The maintenance of an appropriate ratio of body fat to muscle mass is essential for the preservation of health and performance, as excessive body fat is associated with an increased risk of various diseases. Accurate body composition assessment requires precise segmentation of structures. In this study we developed a novel automatic machine learning approach for volumetric segmentation and quantitative assessment of MRI volumes and investigated the efficacy of using a machine learning algorithm to assess muscle, subcutaneous adipose tissue (SAT), and bone volume of the thigh before and after a strength training.

This study aimed to investigate the correlation of the increased volume index of epicardial adipose tissue (EAT) and left ventricular hypertrophy (LVH) in patients with Hypertension (HTN). A total of 209 HTN patients and 50 healthy controls, who underwent cardiovascular magnetic resonance (CMR) at two medical centers in China between June 2015 and October 2024, were enrolled for this study. Postprocessing and imaging analysis were conducted and EAT measurements were performed.

Mitochondrial rRNAs play important roles in regulating mtDNA-encoded gene expression and energy metabolism subsequently. However, the proteins that regulate mitochondrial 16S rRNA processing remain poorly understood. Herein, we generated adipose-specific Wbscr16-/-mice and cells, both of which exhibited dramatic mitochondrial changes.

White adipose tissue (WAT) comprises a plethora of cell types beyond adipocytes forming a regulatory network that ensures systemic energy homeostasis. Intertissue communication is facilitated by metabolites and signaling molecules that are spread by vasculature and nerves. Previous works indicated that WAT responds to environmental cues by adapting the abundance of these "communication routes", however, high intra-tissue heterogeneity questions the informative value of bulk or single cell analyses and underscores the necessity of whole-mount imaging.
