Article Abstract
Adipose tissue plays a crucial role in energy metabolism and endocrine signaling. White adipose tissue (WAT), in particular, is a compelling target for therapeutic interventions in metabolic diseases due to its secretory capacity and abundance. Gene therapies hold promise for reprogramming adipocytes to enhance energy metabolism and facilitate the secretion of therapeutic proteins. Lipid nanoparticles (LNPs) are a promising non-viral delivery vehicle for nucleic acids, but achieving adipocyte-specific transfection is challenging due to the cellular diversity of adipose tissue. Here, we employed a multi-step screening method to optimize mRNA LNPs for adipocyte-preferential transfection, followed by machine learning analysis to identify the features that drive adipocyte selectivity. Furthermore, we demonstrated potent and selective LNP-mediated mRNA delivery to adipocytes in vivo. Our findings highlight the importance of optimizing LNP composition to enhance mRNA transfection efficiency in adipocytes, providing a promising strategy for adipocyte engineering and therapeutic applications.

Body muscle mass versus fat mass: gender-specific associations with NAFLD and liver fibrosis.
Lipids Health Dis
September 2025
Epidemiology, Medical Faculty, University of Augsburg, Stenglingstr. 2, Augsburg, 86156, Germany.
Background: This study aimed to investigate the gender-specific associations of skeletal muscle mass and fat mass with non-alcoholic fatty liver disease (NAFLD) and NAFLD-related liver fibrosis in two population-based studies.
Methods: Analyses were based on data from the MEGA (n = 238) and the MEIA study (n = 594) conducted between 2018 and 2023 in Augsburg, Germany. Bioelectrical impedance analysis was used to evaluate relative skeletal muscle mass (rSM) and SM index (SMI) as well as relative fat mass (rFM) and FM index (FMI); furthermore, the fat-to-muscle ratio was built.
Ultrasound measurements of croup fat thickness and liver echogenicity as indicators for lipomobilization in donkeys (Equus Africanus asinus) with fasting-induced hyperlipidemia.

Background: Disturbances in lipid metabolism are usually associated with hyperlipidemia, which is commonly observed in donkeys with inappetence or anorexia. The diagnostic utility of ultrasound measurements of croup fat thickness (CFT) and relative liver echogenicity for lipomobilization in donkeys with fasting-induced hyperlipidemia was investigated. A prospective observational control study involving 25 donkeys was conducted, and the animals were randomly assigned to a fasting group (FG, n = 20) and a control group (CG, n = 5).

Department of Gastroenterology, Weifang People's Hospital, The First Affiliated Hospital of Shandong Second Medical University, 151 Guangwen Street, Weifang, Shandong, 261000, China.
Background: Current scoring systems for hypertriglyceridaemia-induced acute pancreatitis (HTG-AP) severity are few and lack reliability. The present work focused on screening predicting factors for HTG-SAP, then constructing and validating the visualization model of HTG-AP severity by combining relevant metabolic indexes.
Methods: Between January 2020 and December 2024, retrospective clinical information for HTG-AP inpatients from Weifang People's Hospital was examined.

The stress urinary incontinence (SUI) is a difficulty in urology and current sub-urethral sling treatments are associated with inflamation and recurrence. In this study, we developed a novel tissue-engineered sling with myogenic induced adiposederived stem cells (MI-ADSCs) sheets induced by 5-Aza and combined with electrospun scaffolds of silk fibroin and poly(lactide-co-glycolide) (SF/PLGA) for the treatment of stress urinary incontinence. MI-ADSCs increased α-SMA, MyoD and Desmin the mRNA and protein expression.

Visceral adiposity has been proposed to be closely linked to cognitive impairment. This cross-sectional study aimed to evaluate the predictive value of Chinese Visceral Adiposity Index (CVAI) for mild cognitive impairment (MCI) in patients with type 2 diabetes mellitus (T2DM) and to develop a quantitative risk assessment model. A total of 337 hospitalized patients with T2DM were included and randomly assigned to a training cohort (70%, n = 236) and a validation cohort (30%, n = 101).
