Background: Type-2 diabetes mellitus is a common metabolic disorder characterized by insulin resistance, a relative impairment in insulin secretion, and a certain degree of genetic predisposition. The rapid rise in the prevalence of diabetes mellitus around the world has assisted in the development of new pharmacologically active compounds. The current study was aimed to investigate and validate the anti-diabetic activity of wild-grown plant L.
Material And Methods: molecular docking AutoDock tools 4.2 and glucose uptake assay using yeast cells was performed to investigate the anti-diabetic property of plant . Further, mRNA-based gene ontology enrichment analysis was performed to predict the imitated ontology by the bio-actives from .
Results: The study results reveal that among the 9 active phytoconstituents docked against GLUT-2 protein, α-onocerin possessed the highest binding affinity of -10.23 kcal/mol with no predicted adverse effects and also complies with Lipinski's rule of five. Also, studies reflected in a 5 mM glucose solution, hydro-alcoholic extract of at different concentrations enhanced glucose uptake in yeast cells.
Conclusion: extract enhanced the glucose uptake in yeast cells which may be due to the presence of α-onocerin; possessed the better interaction. Also, no adverse effects were predicted for α-onocerin. Thus, it can be speculated that may possess anti-diabetic activity which may be due to α-onocerin and other related bioactives; needs to be further confirmed experimental studies.

Purpose: To investigate the predictive value of 2-[18F]-fluoro-2-deoxy-D-glucose ([F]FDG) PET/CT for evaluating primary tumor (PT) and lymph node (LN) responses after neoadjuvant programmed death-ligand 1 (PD-L1) blockade monotherapy in patients with locally advanced esophageal squamous cell carcinoma (LA-ESCC).
Methods: In the single-arm phase 1b NATION-1907 trial (NCT04215471), 23 patients with LA-ESCC received two cycles of neoadjuvant PD-L1 blockade Adebrelimab followed by surgery. Among these, 18 patients underwent [F]FDG PET/CT scans both before immunotherapy and prior to surgery.

Enhanced hepatic gluconeogenesis plays an important role in exercise glucose homeostasis when hepatic glycogen stores are depleted. Livers from trained animals demonstrate greater rates of gluconeogenesis in the presence of elevated substrate with and without hormonal stimulation. Training has been reported to have a particularly profound impact on norepinephrine-stimulated gluconeogenesis, but this was only demonstrated in the presence of other gluconeogenic hormones.

Background/aim: The present study aimed to assess the relationship between the maximum standardized uptake value (SUVmax) on F-fluorodeoxyglucose positron emission tomography computed tomography (F-FDG-PET/CT) and the geriatric nutritional risk index (GNRI) in patients with soft-tissue sarcomas (STSs).
Patients And Methods: The present single-center retrospective observational study included patients who underwent F-FDG-PET/CT and for whom serum albumin levels, height, and body weight were measured prior to therapeutic intervention.
Results: A total of 81 patients were included in the study.

Objective: A biallelic missense mutation in mitofusin 2 (MFN2) causes multiple symmetric lipomatosis and partial lipodystrophy, implicating disruption of mitochondrial fusion or interaction with other organelles in adipocyte differentiation, growth and/or survival. In this study, we aimed to document the impact of loss of mitofusin 1 (Mfn1) or 2 (Mfn2) on adipogenesis in cultured cells.
Methods: We characterised adipocyte differentiation of wildtype (WT), Mfn1-/- and Mfn2-/- mouse embryonic fibroblasts (MEFs) and 3T3-L1 preadipocytes in which Mfn1 or 2 levels were reduced using siRNA.

Disulfidptosis is a newly discovered type of regulated cell death triggered by disulfide bond accumulation and NADPH (nicotinamide adenine dinucleotide phosphate) depletion due to glucose deprivation. However, the regulatory mechanisms involving additional cellular circuits remain unclear. Excessive disulfide bond accumulation can impair endoplasmic reticulum (ER) homeostasis and activate the ER stress response.
