A Hepatocyte‐to‐Stellate Cell Axis Couples Alternate‐Day Fasting to Liver Fibrosis Resolution via ATG7 S‐Nitrosylation

open access: yesAdvanced Science, EarlyView.
Alternate‐day fasting suppresses mitochondrial complex II assembly via SDHAF4 to upregulate hepatocyte eNOS. The resulting nitric oxide S‐nitrosylates ATG7 at C184 in hepatic stellate cells, restraining autophagic flux and preventing their profibrotic activation.

Comparison of Salbutamol Delivered Via Jet Nebulizer With A Metered Dose Inhaler (MDI) Plus A Spacer for Asthma Exacerbation of Children: A Randomized Clinical Trial

open access: yesActa Medica Iranica, 2020
Asthma is the most common chronic illness in children and is a major reason for pediatric emergency department visits. Beta-2 agonists are considered the most effective drugs for immediate relief in the symptoms.

Optimizing Cancer Vaccinations Using a Physiologically‐Based Pharmacokinetic/Pharmacodynamic (PBPK/PD) Model

open access: yesAdvanced Science, EarlyView.
Where and when should a cancer vaccine be administered? A whole‐body PBPK model demonstrates that systemic immune transport critically determines vaccination efficacy. By simulating how organ‐specific immune interactions influence treatment response, the study provides a quantitative framework for optimizing cancer vaccination strategies.

Understanding the feasibility and environmental effectiveness of a pilot postal inhaler recovery and recycling scheme

open access: yesnpj Primary Care Respiratory Medicine, 2023
All inhalers have an environmental impact; the majority are not recycled, with many disposed of inappropriately through domestic waste. To assess the feasibility of a method for recovering and recycling inhalers, Chiesi Limited (Chiesi) set up and funded

Relationships among nitrous oxide exposure, neurological injury and biomarkers

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Aims Recreational nitrous oxide (N2O) misuse is an increasing public health problem associated with functional cobalamin (B12) deficiency and severe neurological complications. Despite growing recognition of its harms, the dose–response relationship and clinical value of biomarkers remain unclear.

Twenty years of inhaler therapy: A nationwide drug utilization study

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Aims This study aimed to map nationwide trends and prescribing patterns in inhaler use from 2004 to 2023. In light of evolving clinical guidelines and attention to the environmental impact of inhalers within recent years, we also examined variation in prescribing behaviour and patient‐level treatment choices. Methods Using nationwide health registries,

Adaptive imatinib regimens can mitigate cumulative toxicity while sustaining hemodynamic benefit: A model‐based simulation of the positioning imatinib for pulmonary arterial hypertension trial

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
ABSTRACT Aims Imatinib improves hemodynamics in pulmonary arterial hypertension (PAH), but dose‐dependent toxicity has limited its clinical development. We aimed to quantify the dose–efficacy–toxicity relationship and evaluate alternative dosing strategies using data from the PIPAH trial.

Optimizing the Delivery of Inhaled Medication for Respiratory Patients: The Role of Valved Holding Chambers

open access: yesCanadian Respiratory Journal, 2018
Valved holding chambers (VHCs) have been used with pressurized metered-dose inhalers since the early 1980s. They have been shown to increase fine particle delivery to the lungs, decrease oropharyngeal deposition, and reduce side effects such as throat ...
