Dextromethorphan versus Dextrorphan: A Quantitative Comparison of Antitussive Potency following Separate Administration of Metabolite

open access: yesThe Journal of Clinical Pharmacology, EarlyView.
Abstract To assess the antitussive effects of dextrorphan (DOR) relative to its parent compound, dextromethorphan (DEX) a double‐blind, randomized, placebo‐controlled crossover study was conducted in 23 healthy volunteers using citric acid cough challenge test after administering placebo, DEX, or DOR.

Evaluation of propranolol and quinidine in the treatment of quinidine-resistant arrhythmias [PDF]

open access: yesThe American Journal of Cardiology, 1971
Abstract Combining propranolol and quinidine should improve the antiarrhythmic action of quinidine by blocking beta adrenergic receptors, an action helpful in cases of arrhythmias associated with anesthetic agents, digitalis and stress. To test this hypothesis, 60 patients with paroxysmal arrhythmias resistant to quinidine and 17 with chronic atrial ...

Semiochemical applications for managing the grey field slug (Deroceras reticulatum Müller), a major pest of arable crops

open access: yesPest Management Science, EarlyView.
Trends in semiochemical research highlight promising attractants and repellents for ‘push–pull’ pest control strategies of the grey field slug. Extracts from plants, predators, entomopathogenic fungi, and essential oils demonstrate potential in modifying grey field slug behaviour, inducing avoidance, antifeeding responses, or mortality, offering ...

Assessing Cytochrome P450 Drug Interaction Risk for Dordaviprone Using Physiologically Based Pharmacokinetic Modeling

open access: yesCPT: Pharmacometrics &Systems Pharmacology, EarlyView.
ABSTRACT A physiologically based pharmacokinetic (PBPK) model was developed and verified for dordaviprone, a small molecule with antitumor effects in glioma patients. The model was applied to assess the drug–drug interaction (DDI) potential of dordaviprone as a victim of CYP3A4 inhibitors and inducers, and as a perpetrator of CYP3A4, CYP2C8, CYP2D6 ...

Classification of Platelet‐Activating Anti‐Platelet Factor 4 Disorders

open access: yesInternational Journal of Laboratory Hematology, EarlyView.
ABSTRACT Introduction The prototypic anti‐platelet factor 4 (PF4) disorder—heparin‐induced thrombocytopenia and thrombosis (HITT)—features immunoglobulin G (IgG) class antibodies that activate platelets, monocytes, and neutrophils in a mainly heparin‐dependent fashion via Fcγ receptor‐dependent cellular activation.

Determining properties of human‐induced pluripotent stem cell‐derived cardiomyocytes using spatially resolved electromechanical metrics

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend In this study, we use human‐induced pluripotent stem cell‐derived cardiomyocyte (hiPSC‐CM) experiments and computational modelling to identify the mechanism of action of drug compounds. In the hiPSC‐CM experiments, optical measurements of cell collections are recorded in the baseline case and after drug exposure.

Mathematical model of the zebrafish ventricular cardiomyocyte action potential and calcium transient

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend This study presents the development and validation of the first biophysically detailed computational model of the zebrafish ventricular action potential (AP). The model is based on a human cardiomyocyte framework and reparameterized using published and newly generated patch‐clamp recordings of zebrafish ionic currents.

Developing a quantitative structure–property relationships (QSPR) model using Caco‐2 cell bioavailability indicators (BA) to predict the BA of phytochemicals

open access: yesJournal of the Science of Food and Agriculture, Volume 105, Issue 12, Page 6850-6861, September 2025.
Abstract BACKGROUND The present study aimed to measure bioavailability (BA) indicators, including epithelial barrier function, apparent permeability (Papp) and efflux ratio, of 84 types of phytochemicals using Caco‐2 cell and to develop predictive model systems using machine learning with a quantitative structure–property relationship (QSPR) model ...

Strengths and Opportunities: Clinicians' Perspectives on Palliative Care for Amyotrophic Lateral Sclerosis (ALS) in the United States

open access: yesMuscle &Nerve, Volume 72, Issue 3, Page 455-463, September 2025.
ABSTRACT Introduction/Aims Little is known about the state of palliative care (PC) for people with ALS (pALS) in the U.S. We aimed to examine current practice regarding PC for pALS and how it can be improved. Methods ALS and PC clinicians completed surveys about: (1) strengths and limitations of PC for pALS provided by ALS and PC teams, (2) reasons for

Independent derivations of the axis of arrhythmia for predicting drug‐induced torsades de pointes

open access: yesBritish Journal of Pharmacology, Volume 182, Issue 18, Page 4299-4313, September 2025.
Abstract Background and Purpose: Torsades de pointes is a potentially lethal ventricular arrhythmia that can be induced by many classes of drugs. The risk for a given drug depends upon the combination of cardiac ion channels that it targets. The axis of arrhythmia quantifies that risk. It is a conceptual line in the electrophysiology that describes the
