Artificial Control of Giant Converse Magnetoelectric Effect in Spintronic Multiferroic Heterostructure.

To develop voltage-controlled magnetization switching technologies for spintronics applications, a highly (422)-oriented CoFeSi layer on top of the piezoelectric PMN-PT(011) is experimentally demonstrated by inserting a vanadium (V) ultra-thin layer. The strength of the growth-induced magnetic anisotropy of the (422)-oriented CoFeSi layers can be artificially controlled by tuning the thicknesses of the inserted V and the grown CoFeSi layers. As a result, a giant converse magnetoelectric effect (over 10 s m) and a non-volatile binary state at zero electric field are simultaneously achieved in the (422)-oriented CoFeSi/V/PMN-PT(011) multiferroic heterostructure.

Urinary excretion profiles of the orexin receptor antagonist suvorexant and its metabolites.

Purpose: Suvorexant is an orexin receptor antagonist used in the treatment of insomnia. In this study, we investigated the urinary excretion profiles of suvorexant and its major metabolites, including conjugates, to obtain fundamental information for proving exposure to suvorexant in criminal cases.

Methods: Urine specimens were collected from three subjects for maximum 168 h after a single oral ingestion of suvorexant (10 mg), and suvorexant and its metabolites in urine were determined using liquid chromatography-tandem mass spectrometry with a C18 semi-micro column.

Bilateral vocal cord paralysis following ventriculoatrial shunt placement for hydrocephalus after subarachnoid hemorrhage: illustrative case.

Background: A ventriculoatrial (VA) shunt is an alternative to a ventriculoperitoneal (VP) shunt for managing hydrocephalus, especially when VP shunt insertion is not feasible. Despite its decline in use, the VA shunt remains vital for certain patients. This report highlights a rare complication of bilateral vocal cord paralysis following VA shunt insertion for hydrocephalus secondary to subarachnoid hemorrhage.
