Prothipendyl, a lipophilic neuroleptic drug, requires a careful dosage regimen due to its potential side effects, including life-threatening arrhythmias.This report outlines a case of severe prothipendyl intoxication, its management and the successful utilisation of Intralipid, an intravenous lipid emulsion, in treating ventricular arrhythmia postmassive prothipendyl ingestion. Additionally, the mechanism of action of Intralipid and the rebound concentration of the lipophilic drug in such scenarios are discussed.

The integration of reactive oxygen species (ROS) related photodynamic therapy (PDT) with the strategy of reshaping the tumor microenvironment (TME) has emerged as a potential approach for nanodiagnostic and therapeutic interventions. However, the therapeutic efficacy based on ROS treatments may be hindered by intracellular antioxidants such as glutathione (GSH) and tumor hypoxia. To address these challenges, a nanoplatform based on GSH-responsive multifunctional porphyrinic metal-organic framework (PCN-224@Au@MnO@HA, PAMH) was proposed.

Inflammation is a physiological response of the immune system to infectious agents or tissue injury, which involves a cascade of vascular and cellular events and the activation of biochemical pathways depending on the type of harmful agent and the stimulus generated. The Kunitz peptide HCIQ2c1 of sea anemone is a strong protease inhibitor and exhibits neuroprotective and analgesic activities. In this study, we investigated the anti-inflammatory potential of HCIQ2c1 in histamine- and lipopolysaccharide (LPS)-activated RAW 264.

Objective: The objective of this study was to explore the possibility of treating heart failure in rats by delivering mRNA of 24-dehydrocholesterol reductase (DHCR24) into the body through lipid nanoparticles (LNPs).
Methods: We established a heart failure rat model using doxorubicin. The experiment was divided into blank, model, mRNA stock solution cardiac injection, mRNA stock solution intravenous injection, LNP-mRNA stock solution cardiac injection, and LNP-mRNA stock solution intravenous injection groups.

This study aimed to investigate β-Caryophyllene (BCA) pharmacokinetics as well as the potential antitumor activity and mechanism of action of BCA and eugenol (EU), alone or in combination, in U87 glioblastoma (GB) cells. The BCA pharmacokinetic was studied by evaluating its concentration profiles in rat blood and cerebrospinal fluid after oral and intravenous administration. EU and BCA antitumor mechanisms were assessed by comparing their effects in U87 GB cells and non-tumoral HMC3 cells.

Objectives: Acetate (ACE) and lactate (LAC)-containing balanced resuscitation fluids are commonly used for fluid therapy in cats. These fluids can influence acid-base and electrolyte status. This prospective randomised study compared two balanced crystalloid solutions regarding their effect on acid-base status, electrolytes and LAC concentrations in dehydrated cats after intravenous fluid therapy.
