Unlabelled: Endocrinal products of adipocytes (PPARgamma, A-FABP, E-FABP, leptin, adiponectin and others) modulate insulin tissue sensitivity enabling them to participate in the ethiopathogenesis of diabetes mellitus type 2 (DM2T). Persons with DM2T are characterised by typical changes in lipid spectrum (lower HDL-cholesterol and higherTAG) and in the endocrinal function of subcutaneous adipose tissue; adipocytes produce more PPARgamma, A-FABP and E-FABP and less adiponectin.
Aims Of The Study: To measure chosen markers of metabolic syndrome (MS) in serum and in abdominal subcutaneous adipose tissue in healthy persons and patients with DMT2, to determine basic statistical characteristics of investigated parameters and to discus their role in the genesis and progress of the MS.
Methods: Samples of blood and abdominal subcutaneous adipose tissue were collected from each participant (healthy: 7 men and 8 women; diabetics: 18 men, 11 women) to investigate the levels of HDL, TAG, insulin, C-peptide, glycaemia and the concentrations of A-FABP, E-FABP, leptin, adiponectin, resistin, PPARgamma and TNFalpha.
Results: In most cases the average concentration of investigated parameters in serum was higher in persons with DM 2 regardless of gender. Lower values were only found for HDL and adiponectin. The same situation prevailed in the subcutaneous adipose tissue. Values of most other parameters (A-FABP, E-FABP, and PPARgamma) were also higher in patients. The values of measured parameters not only differed in healthy and in sick persons but depended on gender. The increase/decrease in concrete parameters was greater in diabetic women than diabetic men.
Conclusion: Higher concentrations of A-FABP, E-FABP in serum and in subcutaneous adipose tissue in diabetic persons also higher concentrations of PPARgamma in subcutaneous adipose tissue suggest that these investigated parameters are closely associated with obesity and MS. We can assume that in the near future these parameters will be used in clinical work for diagnosis of this syndrome.

Purpose: This study aimed to evaluate the relationship between the quantity and quality of subcutaneous fat and prognosis following colorectal cancer resection.
Method: We conducted a retrospective analysis of the clinical data of 399 patients who underwent curative resection for stage 2 or 3 colorectal cancer between January 2013 and March 2019. This study examined the correlation between sarcopenia and various fat parameters, including fat area and density, and assessed their impact on the prognosis.

Lipomas are benign soft tissue tumors composed of mature adipocytes, commonly found in subcutaneous tissues. Despite their prevalence in various body regions, they are relatively rare in the oral and maxillofacial regions. This study retrospectively analyzed the clinical and imaging characteristics, as well as the treatment outcomes of 57 patients diagnosed with lipoma.

Pregnant ewes mobilize body fat to increase energy supply for fetal growth and development upon undernutrition, which disrupts the metabolic homeostasis of the body. However, the comprehensive metabolic changes in subcutaneous adipose tissue upon undernutrition are poorly understood. In this study, an undernutrition sheep model was established to investigate the effects of undernutrition on metabolic changes, immune response, and inflammation in subcutaneous fat through transcriptome, RT-qPCR, and metabolome analysis.

Background: Obesity in midlife is a risk factor for developing Alzheimer disease later in life. However, the metabolic and inflammatory effects of body fat varies based on its anatomical localization. In this study, we aimed to investigate the association of MRI-derived abdominal visceral and subcutaneous adipose tissue (VAT and SAT), liver proton-density fat fraction (PDFF), thigh fat-to-muscle ratio (FMR), and insulin resistance with whole-brain amyloid burden in cognitively normal midlife individuals.
