Exposure of PM2.5 can cause different degrees lung injury, which is referred with inflammatory response. Some evidences showed that low-dose radiation (LDR) induces hormesis in immune, however, it unknown if LDR ameliorates the PM2.5-induced injury. Additionally, gut microbiota and inflammation are crucial injury health benefits through need further exploration. Here, we aim to investigate impact on vivo vitro, elucidated potential mechanisms anti-inflammation activated by microbiota. We...

Abstract Respiratory diseases pose a significant global health burden, with challenges in early and accurate diagnosis due to overlapping clinical symptoms, which often leads misdiagnosis or delayed treatment. To address this issue, we developed LungDiag , an artificial intelligence (AI)‐based diagnostic system that utilizes natural language processing (NLP) extract key features from electronic records (EHRs) for the classification of respiratory diseases. This study employed large cohort...

Autophagy plays a double‐edged sword for cancer; particularly, mitophagy important roles in the selective degradation of damaged mitochondria. However, whether is involved killing effects tumor cells by ionizing radiation (IR) and its underlying mechanism remain elusive. The purpose to evaluate mitochondrial ROS (mROS) on autophagy after IR; furthermore, we hypothesized that KillerRed (KR) targeting mitochondria could induce mROS generation, subsequent depolarization, accumulation Pink1,...

Radiation therapy has been a critical and effective treatment for cancer. However, not all cells are destroyed by radiation due to the presence of tumor cell radioresistance. In current study, we investigated effect low-dose (LDR) on suppressive high-dose (HDR) its mechanism from perspective death mode DNA damage repair, aiming provide foundation improving efficacy clinical radiotherapy. We found that LDR pre-irradiation strengthened HDR-inhibited A549 proliferation, HDR-induced apoptosis,...
