Objectives: To observe the expression of brain-derived neurotrophic factor (BDNF) in hypothalamic and adipose tissue in mice with monosodium glutamate (MSG)-induced obesity.
Methods: The effects of hypothalamic lesions, specifically arcuate nucleus (ARC) lesions, induced by MSG injection were studied in male ICR mice at the neonatal stage. The following parameters were compared: body weight, body length, Lee's index, food intake, body temperature, fat weight, and levels of total cholesterol (CHOL), triglyceride (TG), low-density lipoprotein (LDL), high-density lipoprotein (HDL), and blood glucose (GLU). The BDNF expression levels in hypothalamic and adipose tissue were measured using western blotting. Results Compared with the control group, the model group body had significantly higher weight, Lee's index, food intake, fat weight, CHOL, TG, LDL, HDL, and GLU levels. BDNF expression levels in hypothalamic and adipose tissue were markedly down-regulated in the model group.
Discussion: BDNF may be closely associated with MSG-induced hypothalamic obesity.

Introduction: The purpose of this study was to evaluate the association between body composition, overall survival, odds of receiving treatment, and patient-reported outcomes (PROs) in individuals living with metastatic non-small-cell lung cancer (mNSCLC).
Methods: This retrospective analysis was conducted in newly diagnosed patients with mNSCLC who had computed-tomography (CT) scans and completed PRO questionnaires close to metastatic diagnosis date. Cox proportional hazard models and logistic regression evaluated overall survival and odds of receiving treatment, respectively.
Epicardial Adipose Tissue from Computed Tomography: a Missing Link in Premature Coronary Artery Disease?

Purpose: Epicardial adipose tissue (EAT) could contribute to the specific atherosclerosis profile observed in premature coronary artery disease (pCAD) characterized by accelerated plaque burden (calcified and non-calcified), high risk plaque features (HRP) and ischemic recurrence. Our aims were to describe EAT volume and density in pCAD compared to asymptomatic individuals matched on CV risk factors and to study their relationship with coronary plaque severity extension and vulnerability.
Materials And Methods: 208 patients who underwent coronary computed tomography angiography (CCTA) were analyzed.
Sarcopenia is defined as a muscle-wasting syndrome that occurs with accelerated aging, while cachexia is a severe wasting syndrome associated with conditions such as cancer and immunodeficiency disorders, which cannot be fully addressed through conventional nutritional supplementation. Sarcopenia can be considered a component of cachexia, with the bidirectional interplay between adipose tissue and skeletal muscle potentially serving as a molecular mechanism for both conditions. However, the underlying mechanisms differ.

We previously identified the mitochondrial protein 4-Nitrophenylphosphatase Domain and Non-Neuronal SNAP25-Like 1 (Nipsnap1) as a novel regulatory factor that integrates with lipid metabolism and is critical to sustain the long-term activation of BAT, but the precise mechanism and function of Nipsnap1 is unknown.
Objectives: Define how the regulatory factor Nipsnap1 integrates with lipid metabolism.
Background: Type 2 Diabetes Mellitus (T2DM) is a significant public health burden. Emerging evidence links volatile organic compounds (VOCs), such as benzene to endocrine disruption and metabolic dysfunction. However, the effects of chronic environmentally relevant VOC exposures on metabolic health are still emerging.
