Role of IPF genetic risk loci in post-COVID-19 lung abnormalities: a cohort study.
BMJ Open Respir Res
January 2025
Division of Respiratory Medicine, University of British Columbia, Vancouver, British Columbia, Canada.
Introduction: Persistent lung abnormalities following COVID-19 infection are common. Similar parenchymal changes are observed in idiopathic pulmonary fibrosis (IPF). We investigated whether common genetic risk factors in IPF are associated with developing lung parenchymal abnormalities following severe COVID-19 disease.

Background: It has been proposed that repeated exposure of bronchial epithelial cells to atmospheric particulate matter (PM) could disrupt airway epithelial integrity and lead to epithelial-to-mesenchymal transition (EMT) and ultimately airway remodeling. The molecular mechanisms underlying PM-related bronchial epithelial EMT have not yet been elucidated. The aim of this research is to clarify the molecular mechanism of EMT upon PM exposure.

The endocannabinoid system's significance in maintaining blood-brain barrier (BBB) integrity under physiological and pathological conditions is suggested by several reports, but the underlying molecular mechanisms are not well understood. In this paper, we investigated the effects of depletion of 2-arachidonoylglycerol (2-AG), one of the main endocannabinoids in the central nervous system, on BBB integrity using pharmacological tools. Female Sprague-Dawley rats were injected with the diacylglycerol lipase α (DAGLα) inhibitor LEI-106 (40 mg/kg, i.

Lampreys are early jawless vertebrates that are the key to understanding the evolution of vertebrates. However, the lack of cytomic studies on multiple lamprey organs has hindered progress in this field. Therefore, the present study constructed a comprehensive cell atlas comprising 604,460 cells/nuclei and 70 cell types from 14 lamprey tissue samples.

January 2025
Neurology department, Royal Brisbane and Women's Hospital, Brisbane, Australia.
Objectives: There have been conflicting reports about the frequency of neural autoantibodies in epilepsy cohorts, which is confounded by the lack of clear distinction of epilepsy from acute symptomatic seizures due to encephalitis. The aim of this study was to determine the frequency of neural autoantibodies in a well characterised population of refractory focal epilepsy of known and unknown cause.
Methods: Cases were recruited from epilepsy outpatient clinics at the Princess Alexandra, Mater, Royal Brisbane and Women's and Cairns Base Hospitals from 2021 - 2023.
