Novel graphene electrochemical transistors incorporating zirconia inorganic molecular imprinted layer :Design, construction and application for highly sensitive and selective detection of acetaminophen
Anal Chim Acta. 2023 Aug 15;1269:341405. doi: 10.1016/j.aca.2023.341405. Epub 2023 May 22.ABSTRACTOwing to their intrinsic amplifying effect together with chemical stability, graphene electrochemical transistor sensors (GECTs) are gaining momentum for sensing applications. However, the surface of GECTs for different detection substances must be modified with different recognition molecules, which was cumbersome and lack a universal method. Molecularly imprinted polymer (MIP) is a kind of polymer with specific recognition function for given molecules. Here, MIP and GECTs were combined to effectively solve the problem of wea...

Titanate nanotubes as an efficient oral detoxifying agent against drug overdose: application in rat acetaminophen poisoning
Nanoscale Adv. 2023 Apr 25;5(11):2950-2962. doi: 10.1039/d2na00874b. eCollection 2023 May 30.ABSTRACTVoluntary drug intoxication is mainly due to drug overdose or the interaction of several drugs. Coma and its associated complications such as hypoventilation, aspiration pneumopathy, and heart rhythm disorders are the main hallmarks of drug intoxication. Conventional detoxification treatments, including gastric lavage or vomiting, administration of ipecac or activated charcoal (CH), and the use of antidotes, have proven to be inefficient and are generally associated with severe adverse effects. To overcome these limitations...

Peli3 ablation ameliorates acetaminophen-induced liver injury through inhibition of GSK3 β phosphorylation and mitochondrial translocation
Exp Mol Med. 2023 Jun 1. doi: 10.1038/s12276-023-01009-w. Online ahead of print.ABSTRACTThe signaling pathways governing acetaminophen (APAP)-induced liver injury have been extensively studied. However, little is known about the ubiquitin-modifying enzymes needed for the regulation of APAP-induced liver injury. Here, we examined whether the Pellino3 protein, which has E3 ligase activity, is needed for APAP-induced liver injury and subsequently explored its molecular mechanism. Whole-body Peli3-/- knockout (KO) and adenovirus-mediated Peli3 knockdown (KD) mice showed reduced levels of centrilobular cell death, infiltration ...

Pharmacokinetics and repeated dose 28-day oral toxicity studies of acetaminophen nanosuspension
In this study, an attempt was made to improve oral bioavailability and reduce the toxicity of acetaminophen using nanosuspension technology. The acetaminophen nanosuspensions (APAP-NSs) were prepared by a nano-precipitation method using polyvinyl alcohol and hydroxypropylmethylcellulose as stabilizers. The mean diameter of APAP-NSs was 124 ± 3.8 nm. The dissolution profile of APAP-NSs was significantly point-to-point higher than the coarse drug in simulated gastrointestinal fluids. The in vivo study revealed 1.6- and 2.8-fold increases in the AUC0-inf and Cmax of the drug, respectively, in APAP-NSs-receiving animals compa...

Early treatment with N-acetylcysteine reduces hepatotoxicity in acute acetaminophen poisoning
We reported a case of a 15-year- old girl referred to our Emergency Department 3 hours after ingestion of 10 g of paracetamol for suicidal purposes. She promptly started the administration of intravenous N-acetylcysteine (NAC) and the patient was discharged after 5 days of hospitalization in good clinical condition and with neuropsychiatric follow-up. Our case shows that the timing of the intravenous NAC administration is considered the most important factor in the prevention of acetaminophen-induced hepatic failure, despite high serum levels after acetaminophen ingestion.PMID:37247196 | DOI:10.23750/abm.v94iS1.13714
