Unlabelled: Gene PPARgamma is one of the pivotal factors that influence adipocyte differentiation. It is transcriptional factor that plays a crucial role in the regulation of genes involved in lipid utilisation and storage as well as insulin action. The aim of this study was to evaluate whether PPARgamma Pro12Ala and Pro115Gln polymorphisms are connected with obesity and its anthropological parameters.
Material And Methods: we investigated 93 subjects: 72 women (37 non-obese and 35 obese) and 21 men (8 non-obese and 13 obese). We performed anthropological examination: BMI, WHR and total-body densitometry in the whole group. PPARg polymorphism was studied using PCR and RFLP.
Results: Pro12Pro ("wild" type) variant was present in 57 subjects (32 obese and 25 non-obese): 45 women (26 obese and 19 non-obese) and 12 men (6 obese and 6 non-obese). Heterozygosity Pro12Ala was observed in 20 subjects (8 obese and 12 controls): 15 women (4 obese and 11 lean) and 5 men (4 obese). Homozygosity Ala12Ala was discovered in 16 subjects (8 obese and 8 controls): 12 women (5 obese and 7 non-obese) and 4 men (3 obese). Pro115Gln variant was not found in any of the studied subjects.
Conclusions: The frequency Ala allele (pro12Ala and Ala12Ala variant) was 28% in the whole group and 25% in the obese subjects. However the Pro12Ala polymorphism is quite common, it does not seem to be directly connected with onset of obesity. But it is interesting that the Ala allele is more frequent in non-obese women comparing to obese women (33 vs 20%). Reverse tendency was seen in men. Pro12Ala and/or Ala12Ala polymorphism is twice more frequent in obese subjects comparing to non-obese ones (38 vs 19%).

Maximal physical effort induces a disturbance in the body's energy homeostasis and causes oxidative stress. The aim of the study was to determine whether prooxidant-antioxidant balance disturbances and the secretion of adipokines regulating metabolism, induced by maximal intensity exercise, are dependent on body composition in young, healthy, non-obese individuals. We determined changes in the concentration of advanced protein oxidation products (AOPP), markers of oxidative damage to nucleic acids (DNA/RNA/ox), and lipid peroxidation (LPO); catalase (CAT), superoxide dismutase (SOD), and glutathione peroxidase (GPx) activity, as well as concentrations of visfatin, leptin, resistin, adiponectin, asprosin, and irisin in the blood before and after maximal intensity exercise in men with above-average muscle mass (NFAT-HLBM), above-average fat mass (HFAT-NLBM), and with average body composition (NFAT-NLBM).

Background: Sarcopenia is prevalent among hemodialysis patients and is associated with poor outcomes. The neutrophil-to-lymphocyte ratio (NLR), an easily obtainable marker of inflammation, may predict sarcopenia risk. This study aimed to investigate the association between NLR and sarcopenia risk in maintenance hemodialysis patients, examining this association in the context of obesity.

Background: We hypothesized that patients with coarctation of aorta (COA) and obesity would have more advanced cardiovascular remodeling and impaired aerobic capacity compared to COA patients without obesity. The purpose of this study was to assess the relationship between obesity, cardiovascular remodeling, and aerobic capacity in adults with repaired COA.
Method: The study comprised of 3 groups: (1) Obese COA group (n=177) (COA patients with body mass index [BMI] >30 kg/m); (2) Non-obese COA group (n=572) (COA patients with BMI ≤30 kg/m); (3) Control group (n=59) (subjects without structural heart disease and BMI ≤30 kg/m).

Purpose: To identify the key craniofacial anatomic characteristics associated with the prevalence of severe obstructive sleep apnea (OSA) in patient cohorts stratified by age and body mass index (BMI).
Methods: This prospective study was conducted at the Beijing Anzhen Hospital Center for Sleep Medicine and Science between December 2023 and March 2024. Patients suspected of having OSA underwent overnight polysomnography, along with computed tomography scans of the head and neck, to evaluate the skeletal and soft tissue characteristics.

Proper differentiation of bone marrow stromal cells (BMSCs) into adipocytes is crucial for maintaining skeletal homeostasis. However, the underlying regulatory mechanisms remain incompletely understood, posing a challenge for the treatment of age-related osteopenia and osteoporosis. Here, through comprehensive gene expression analysis during BMSC differentiation into adipocytes, we identified the forkhead transcription factor Foxk2 as a key regulator of this process.
