Magnetic Resonance Imaging of Inner Ear and Internal Auditory Canal Structures in the Presence of a Cochlear Implant.

Objective: To determine whether the internal auditory canal (IAC) can be visualized using magnetic resonance imaging (MRI) in users of a cochlear implant (CI) model that can safely undergo MRI at 3 T.

Patients: Four normally hearing controls and three individuals unilaterally implanted with a HiRes Ultra 3D (Advanced Bionics LLC, California, USA).

Interventions: Participants underwent 3 T MRI using sequences appropriate for the postoperative surveillance of the IAC.

Patient Experience Regarding Medication-Related Information Received in a Rural Private Polyclinic Setting in Vietnam.

Inadequate provision of medication-related information can lead to nonadherence to treatment. This study aims to investigate patient satisfaction regarding medication-related information provided by healthcare professionals and to identify factors associated with patient experience regarding information. A cross-sectional descriptive study was conducted in October 2023 among 400 patients at a rural private polyclinic in Ben Tre, Vietnam by using a self-administered questionnaire.

BBL enzymes exhibit enantiospecific preferences in the biosynthesis of pyridine alkaloids in Nicotiana tabacum L.

Plant species can accumulate secondary metabolites in optically pure form or, occasionally, as enantiomeric mixtures. Interestingly, enantiomers of the same molecule can confer different biological activities. In tobacco (Nicotiana tabacum L.

Cost-related medication nonadherence in the Mekong Delta, Vietnam.

Background: Cost-related nonadherence (CRN) to prescription medication has been shown to affect healthcare outcomes. While CRN has been reported in many countries globally, it has not been fully characterized in Vietnam.

Objectives: This study was conducted to determine CRN rates and factors associated with CRN among pharmacy customers in the Mekong Delta, Vietnam.

Nitrate assimilation pathway is impacted in young tobacco plants overexpressing a constitutively active nitrate reductase or displaying a defective CLCNt2.

Background: We have previously shown that the expression of a constitutively active nitrate reductase variant and the suppression of CLCNt2 gene function (belonging to the chloride channel (CLC) gene family) in field-grown tobacco reduces tobacco-specific nitrosamines (TSNA) accumulation in cured leaves and cigarette smoke. In both cases, TSNA reductions resulted from a strong diminution of free nitrate in the leaf, as nitrate is a precursor of the TSNA-producing nitrosating agents formed during tobacco curing and smoking. These nitrosating agents modify tobacco alkaloids to produce TSNAs, the most problematic of which are NNN (N-nitrosonornicotine) and NNK (4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone).
