Article Abstract
Objective: To determine whether an inflammatory challenge induces insulin resistance in horses and examine possible contributions of adipose tissue to inflammatory cytokine production.
Animals: 15 adult mares.
Procedures: Lipopolysaccharide (0.045 mug/kg, IV) or saline solution was administered, and insulin sensitivity was determined by means of the hyperinsulinemic, euglycemic clamp procedure or an adipose tissue biopsy was performed. Adipose tissue samples were collected, and mature adipocytes were obtained. Mature adipocytes were stimulated with lipopolysaccharide or dedifferentiated into preadipocytes and then stimulated with lipopolysaccharide. Interleukin-1, interleukin-6, and tumor necrosis factor A expression in blood, adipose tissue, and adipocytes was quantified with a real-time, reverse transcriptase- PCR assay.
Results: Lipopolysaccharide induced a transient increase in insulin sensitivity followed by a reduction in insulin sensitivity at 24 hours. Increased cytokine expression was observed in blood and adipose tissue following administration of lipopolysaccharide, and adipocytes and preadipocytes stimulated with lipopolysaccharide stained positive for tumor necrosis factor A. Expression of interleukin-1, interleukin-6, and tumor necrosis factor A was detected in preadipocytes stimulated with lipopolysaccharide, and interleukin-6 and tumor necrosis factor A were detected in mature adipocytes stimulated with lipopolysaccharide.
Conclusions And Clinical Relevance: Results indicated that insulin resistance develops following systemic inflammation in horses and suggested that adipose tissue may contribute to this inflammatory response. Methods to regulate insulin sensitivity may improve clinical outcome in critically ill patients.

Propiconazole is a triazole fungicide previously shown to induce triglyceride accumulation in human liver HepaRG cells, potentially via activation of the Pregnane X Receptor (PXR). However, whether propiconazole can disrupt hepatic and whole-body metabolism in vivo is currently unknown. Therefore, we aimed to examine the metabolic effects of propiconazole in the context of metabolic dysfunction-associated steatotic liver disease (MASLD), obesity, and insulin resistance.

In tissues of toothed whales from the Adriatic Sea (muscle, liver, kidney, lung, spleen, adipose tissue and skin) the concentrations of cadmium (Cd), lead (Pb) and arsenic (As) were analysed. In total, 186 dolphins were analysed; 155 bottlenose (Tursiops truncatus), 25 striped (Stenella coeruleoalba) and 6 Risso's dolphins (Grampus griseus). Cadmium concentrations in tissue samples ranged from 0.

The induction of adipose thermogenesis plays a critical role in maintaining body temperature and improving metabolic homeostasis to combat obesity. β3-adrenoceptor (β3-AR) is widely recognized as a canonical β-adrenergic G-protein-coupled receptor (GPCR) that plays a crucial role in mediating adipose thermogenesis in mice. Nonetheless, the limited expression of β3-AR in human adipocytes restricts its clinical application.

Immune cell infiltration into adipose tissue (AT) is a key factor in type 2 diabetes (T2DM). However, research on the impact of fat distribution on immune cells and immune responses in women is still lacking. This study used enrichment, protein-protein interaction network, immune cell infiltration, and correlation analysis to compare the similarities and differences between the transcriptome data of visceral AT (VAT) and subcutprotein-proteinaneous AT (SAT) obtained from the omprehensive database of gene expression in women with non-T2DM and T2DM.

To evaluate the relationship between the muscle mass-to-fat ratio (MMFR) at the third lumbar spine (L3) and overall survival (OS) as well as related complications after pancreaticoduodenectomy (PD) for pancreatic cancer. Patients who underwent PD for pancreatic cancer between March 2017 and May 2023 at the Second Affiliated Hospital of Soochow University were included. Muscle mass and fat content at the L3 were measured by computed tomography.
