Family-based case-control study of exposure to household humidifier disinfectants and risk of idiopathic interstitial pneumonia.

PLoS ONE, 2019
BackgroundIn Korea, several household humidifier disinfectants (HDs) were clinically confirmed to cause HD-associated lung injury (HDLI). Polyhexamethylene guanidine (PHMG) phosphate is the main ingredient of the HDs found to be associated with lung ...

Occupational interstitial lung diseases

Journal of Internal Medicine, Volume 294, Issue 6, Page 798-815, December 2023., 2023
Abstract Millions of workers are exposed to substances known to cause occupational interstitial lung diseases (ILDs), particularly in developing countries. However, the burden of the disease is likely to be underestimated due to under‐recognition, under‐reporting or both.

Oleanolic acid regulates the proliferation and extracellular matrix of keloid fibroblasts by mediating the TGF‐β1/SMAD signaling pathway

Journal of Cosmetic Dermatology, Volume 22, Issue 7, Page 2083-2089, July 2023., 2023
Abstract Background Keloid (KD) is a unique pathological fibroproliferative disease that seriously affects the appearance of patients. This study investigated the effect of oleanolic acid (OA) on the proliferation of keloid fibroblasts (KFs) and the expression of extracellular matrix (ECM)‐related proteins.
