Biochemical parameters of transformation of fresh subcutaneous fat into adipocere have been studied in experiment. Activation of lipid peroxidation is a significant component of the mechanism of adipocere transformation, which is proven by a drastic increase in the level of Schiff's bases in adipocere in comparison with subcutaneous fat. The concentrations of myristic, palmitic, and stearic fatty acids increase during the formation of adipocere, while the content of linoleic acid decreases in comparison with the unchanged human subcutaneous fat.

Steatotic liver disease (SLD) represents a multisystem disease and is a common complication of childhood obesity. We studied fat content at the abdominal level (liver, subcutaneous, and visceral) and the response to childhood obesity management. In this retrospective longitudinal study, 8-18-year-olds with a body mass index (BMI) z-score above 1.

Fatty acid can potentially serve as biomarker for evaluating metabolic disorder and inflammation condition, and quantifying the double bonds is the key for revealing fatty acid information. This study presents an assessment of a deep learning approach utilizing deep image prior (DIP) for the quantification of double bonds and methylene-interrupted double bonds of triglyceride derived from chemical-shift encoded multi-echo gradient echo images, all achieved without the necessity for network training. The methodology implemented a cost function grounded in signal constraints to continually refine the neural network's parameters on a single slice of images through iterative processes.

Background: Deep learning (DL)-based adipose tissue segmentation methods have shown great performance and efficacy for adipose tissue distribution analysis using magnetic resonance (MR) images, an important indicator of metabolic health and disease. The aim of this study was to evaluate the reproducibility of whole-body adipose tissue distribution analysis using proton density fat fraction (PDFF) images at different MR strengths.
Methods: A total of 24 volunteers were imaged using both 1.

Background: With rising demand for non-invasive body contouring, this study aimed to evaluate the efficacy and safety of non-focused, low-intensity ultrasound for lower abdominal lipolysis.
Methods: The enrolled subjects prospectively received 6 weekly sessions of well-setting ultrasound treatment with frequency of 1 MHz and an intensity of 2.2 W/cm2, to target the subcutaneous fat of lower abdomen with three regions (left, middle, and right).

Objectives: To investigate baseline patient characteristics associated with the risk of computed tomography (CT)-based sarcopenia and assess whether sarcopenia and other morphometric parameters influence survival outcomes in patients with liver metastases and cholangiocarcinoma after Yttrium-90 radioembolization.
Materials And Methods: We retrospectively analyzed 120 cancer patients (mean age, 62 ± 13.3 years, 61 men) who underwent preprocedural CT.
