Department of Basic Medical Sciences, Manipal, Manipal Academy of Higher Education, Manipal, Karnataka, India.
Background: Excessive fluoride exposure leads to increased oxidative stress and lipid peroxidation, causing harmful effects on the metabolic organs in the human body. Betanin, a pigment obtained from beetroot, is seen to have powerful anti-inflammatory and antioxidant. The study was conducted to determine the role of betanin in fluoride induced hepato-renal toxicity in Wistar rats.

This study aimed to evaluate the antihyperglycemic and antioxidant activities of the lectin isolated from (BTL). Diabetes was induced in Wistar rats through low-dose streptozotocin injections. Following the confirmation of hyperglycaemia, the animals were treated with 150 mM NaCl, glibenclamide, or BTL at 600 or 900 mg/kg.

Several potent carcinogenic nitrosamines, including N-nitrosodiethylamine (NDEA) and N-nitrosodimethylamine (NDMA), induce micronuclei in the micronucleated hepatocyte (MNHEP) assay but not in the micronucleated reticulocyte (MNRET) assay. However, the MNHEP assay is not as frequently used as the MNRET assay for evaluating in vivo genotoxicity. The present study evaluated MN formation in the liver of Big Blue transgenic rats exposed to four small-molecule nitrosamines, NDMA, N-nitrosodiisopropylamine (NDIPA), N-nitrosoethylisoporpylamine (NEIPA), and N-nitrosomethylphenylamine (NMPA), using a repeat-dose protocol typically used for in vivo mutagenicity studies.

Introduction: MRTX1133 is a selective and reversible small molecule inhibitor of KRAS (G12D), which significantly delays the progression of solid tumors. However, no study on the absorption, distribution, and excretion of MRTX1133.
Methods: A fast ultra-high performance liquid chromatography-tandem quadrupole mass spectrometry method was developed for the determination of MRTX1133 in rat plasma, tissue homogenate, and urine.

Purpose: Tacrolimus could induce hepatotoxicity during clinical use, and the mechanism was still unclear, which posed new challenge for the prevention and treatment of tacrolimus-induced hepatotoxicity. The aim of this study was to investigate the mechanism of tacrolimus-induced hepatotoxicity and provide reference for drug development target.
Methods: In this study, biochemical analysis, pathological staining, immunofluorescent staining, immunohistochemical staining, transcriptomic analysis, Western blotting was used to investigate the mechanism of tacrolimus-induced hepatotoxicity in gene knockout mice and Wistar rats.
