Rat models of postintracerebral hemorrhage pneumonia induced by nasal inoculation with or intratracheal inoculation with LPS.
Front Immunol
January 2025
State Key Laboratory of Traditional Chinese Medicine Syndrome, Department of Neurology, Guangdong Provincial Academy of Chinese Medical Sciences, Guangdong Provincial Hospital of Chinese Medicine, The Second Affiliated Hospital of Guangzhou University of Chinese Medicine, Guangzhou, China.
Background: A stable and reproducible experimental bacterial pneumonia model postintracerebral hemorrhage (ICH) is necessary to help investigating the pathogenesis and novel treatments of Stroke-associated pneumonia (SAP).
Aim: To establish a Gram-negative bacterial pneumonia-complicating ICH rat model and an acute lung injury (ALI)-complicating ICH rat model.
Methods: We established two standardized models of post-ICH pneumonia by nasal inoculation with () or intratracheal inoculation with lipopolysaccharide (LPS).
Respiratory symptoms after coalmine fire and pandemic: A longitudinal analysis of the Hazelwood Health Study adult cohort.
PLOS Glob Public Health
January 2025
School of Public Health and Preventive Medicine, Monash University, Melbourne, VIC, Australia.
The aim of this study was to determine whether the effects of extreme but discrete PM2.5 exposure from a coal mine fire on respiratory symptoms abated, persisted, or worsened over time, and whether they were exacerbated by COVID-19. We analysed longitudinal survey data from a cohort residing near a 2014 coalmine fire in regional Australia.

January 2025
Department of Medicine, National University Hospital, NUHS Tower Block, Level 10, 1E Kent Ridge Road, Singapore, 119228, Singapore.
Purpose: Tuberculosis (TB) is a highly contagious infection and one of the world's leading causes of death from a single infectious agent. Currently, TB diagnosis can be established via mycobacterial cultures, Acid Fast Bacilli smear and molecular studies. In the ever-evolving landscape of medical advancements, breath tests have shown considerable promise.

Front Allergy
January 2025
Unit of Otorhinolaryngology-Head and Neck Department, ASST Sette Laghi, Varese and UPLOAD (Upper and Lower Airways Diseases) Research Centre, University of Insubria, Varese, Italy.
Background: Chronic rhinosinusitis with nasal polyps (CRSwNP) is an inflammatory condition characterized by persistent nasal obstruction, discharge, facial pressure, and olfactory dysfunction. CRSwNP significantly impairs quality of life (QoL), with olfactory loss being a particularly distressing symptom that affects food enjoyment, personal safety, and social interactions.
Methods: This study investigated the experiences of Italian patients with CRSwNP.
LPCAT1 reduces inflammatory response, apoptosis and barrier damage of nasal mucosal epithelial cells caused by allergic rhinitis through endoplasmic reticulum stress.
Tissue Cell
December 2024
Department of Facial Features, 970 Hospital, Joint Service Support Force of the Chinese People's Liberation Army, Yantai, Shandong, China. Electronic address:
Allergic rhinitis (AR), common in children and adolescents, involves Lysophosphatidylcholine acyltransferase 1 (LPCAT1) catalyzing surfactant lipid biosynthesis and suppressing endoplasmic reticulum expression. However, the precise mechanism underlying the impact of LPCAT1 on epithelial cell damage in AR remains elusive. Hence, the present investigation elucidated the potential effect of LPCAT1 on epithelial cell damage in AR by inhibiting endoplasmic reticulum stress.
