A 43-year-old man, with no history of cardiac disease, deliberately ingested 4 tablets of a rodenticide containing 12 mg of scilliroside. Vomiting appeared a few minutes later and persisted for 48 hours. At the 20th hour, when he was admitted, EKG revealed a complete atrio-ventricular block which disappeared only on the 4th day. The repolarization abnormalities characteristic of digitalization persisted still further until the 12th day.

Objective: To investigate the protective effect and mechanism of tumor necrosis factor receptor-associated factor 6 (TRAF6) inhibitor C25-140 on acute kidney injury (AKI) induced by acute diquat (DQ) poisoning in mice.
Methods: A total of 80 SPF grade healthy male C57BL/6 mice were randomly divided into the normal control group, DQ model group, C25-140 intervention group, and C25-140 control group, with 20 mice in each group. The DQ poisoning mouse model was established by using one-time intraperitoneal injection of 1 mL of 40 mg/kg DQ solution.

The human Cell Line Activation Test (h-CLAT) is an in vitro skin sensitization assay adopted by the OECD as Test Guideline 442E. In the h-CLAT, 2,4-dinitrochlorobenzene (DNCB) is used as a positive control; however, DNCB is considered a poisonous substance under the Poisonous and Deleterious Substances Control Act in Japan since 2014 because of its high acute toxicity. Strict control, handling, and storage are required when using DNCB, which is a burden to the users.

Acute liver failure (ALF) is a life-threatening condition that occurs when the liver sustains severe damage and rapidly loses its function. The primary cause of ALF is the overdose of acetaminophen (APAP), and its treatment is relatively limited. The involvement of the complement system in the development of ALF has been implicated.

Acute liver failure (ALF) is characterized by rapid hepatic dysfunction, primarily caused by drug-induced hepatotoxicity. Due to the lack of satisfactory treatment options, ALF remains a fatal clinical disease, representing a grand challenge in global health. For the drug repositioning to ALF of mesalamine, which is clinically approved for the treatment of inflammatory bowel disease (IBD), we propose a supramolecular prodrug nanoassembly (SPNs).

Introduction: Sodium nitrite is a potent oxidizer, which may precipitate rapidly lethal methemoglobinemia. Prompt diagnosis and treatment may salvage otherwise fatal cases. It is unclear if emergency departments are prepared for increasing cases.
