Abstract Background Oxidative stress is a significant feature in the pathomechanism of neurodegenerative diseases. Thus, the search for an effective and safe novel antioxidant agent with neuroprotective properties has increased the interest in medicinal plant products as a bioactive phytochemical source. However, little is known about the potential effects of the medically important Glaucium corniculatum as a natural antioxidant. Objective In the present study, it was aimed to investigate the an...

Abstract The prevalence of diabetes is rapidly increasing worldwide and is highly associated with the incidence of depression. Pioglitazone, a Peroxisome proliferator-activated receptor gamma (PPAR-γ) agonist, is widely used for treating patients with type 2 diabetes. However, whether pioglitazone alleviates metabolic disorder-related depression and astrocytic deficits remains unclear. Here we showed that 12 weeks of high-fat diet (HFD) feeding (from 8- to 20-week-old) induced not only obesity a...
Abstract Aims Glavonoid-rich oil (GRO) derived from ethanol extraction of licorice (Glycyrrhiza glabra Linne) root has been reported to have beneficial effects on health. In this study, we aimed to determine the effect of long-term administration of GRO on metabolic disorders and to elucidate the molecular mechanism. Main methods Female obese, type 2 diabetic KK-Ay mice were fed diets supplemented with 0.3% or 0.8% GRO (w/w) for 4–12 weeks. Mice were euthanized and autopsied at 20 weeks old. The...
Abstract Interactions between vascular smooth muscle cells (VSMCs), endothelial cells (ECs), pericytes (PCs) and macrophages (MФ), the major components of blood vessels, play a crucial role in maintaining vascular structural and functional homeostasis. Low-density lipoprotein (LDL) receptor-related protein-1 (LRP1), a transmembrane receptor protein belonging to the LDL receptor family, plays multifunctional roles in maintaining endocytosis, homeostasis, and signal transduction. Accumulating evid...
Abstract Diabetes mellitus causes changes in metabolism of extracellular nucleotides acting through P2 receptors (P2Rs). This affects renal function and may lead to glomerular and tubular disturbances. We measured urinary excretion of nucleotides (ATP, ADP, AMP, UTP, UDP, UMP) in streptozotocin-induced diabetic rats (65 mg/kg, i.p., day 0) and the effects of P2Rs’ blockade by suramin (10 mg/kg, i.p., days +7, +14) on glomerular P2×7R expression and urinary excretion of glomerular (albumin, nephr...

Abstract This study aimed to evaluate the anti-inflammatory effect of Auraptene (AUR) and Umbelliprenin (UMB) in a rat model of rheumatoid arthritis (RA) induced by using complete Freund's adjuvant (CFA). Paw swelling of adjuvant arthritis rats measured at various times after CFA injection. Over 15 days of RA induction, mediator/cytokine-mediated processes involved in managing the regulation and resolving RA's inflammation were also quantified with ELISA. Histopathological changes were also asse...
Abstract Background The field bean (Vicia faba) is a valuable fodder plant of the Fabaceae family, grown as a main crop for its seed yield. Its phytochemical profile is characterized by the presence of a range of compounds with various biological activities. Purpose The present study investigates the phytochemical profile of the extract from mature seeds of Vicia faba var. minor and examines its impact on preventing oxidative damage to various lipids, protein and DNA molecules in vitro. Methods ...
Abstract The current study investigates the biochemical and histopathological effects of taxifolin on acrylamide-induced kidney damage. A 50 mg/kg dose of taxifolin was administered via oral gavage to the taxifolin + acrylamide (TACR) group (n-6) consisting of male albino Wistar rats. The same volume of distilled water used as solvent was orally administered to the acrylamide (ACR) (n-6) and healthy (HG) (n-6) groups. One hour after the administration of taxifolin and distilled water, a 20 mg/kg...
