Air pollution is one of the top five causes of death in the world and has become a research hotspot. In the past, the health effects of particulate matter (PM), the main component of air pollutants, were mainly focused on the respiratory and cardiovascular systems. However, in recent years, the intestinal damage caused by PM and its relationship with gut microbiome (GM) homeostasis, thereby affecting the composition and function of GM and bringing disease burden to the host lung through different mechanisms, have attracted more and more attention. Therefore, this paper reviews the latest research progress in the effect of PM on GM-induced lung damage and its possible interaction pathways and explores the potential immune inflammatory mechanism with the gut-lung axis as the hub in order to understand the current research situation and existing problems, and to provide new ideas for further research on the relationship between PM pollution, GM, and lung damage.

This research was carried out to assess the concentrations of carbon monoxide (CO) and formaldehyde (HCHO) in Edo State, Southern Nigeria, using remote sensing data. A secondary data collection method was used for the assessment, and the levels of CO and HCHO were extracted annually from Google Earth Engine using information from Sentinel-5-P satellite data (COPERNISCUS/S5P/NRTI/L3_) and processed using ArcMap, Google Earth Engine, and Microsoft Excel to determine the levels of CO and HCHO in the study area from 2018 to 2023. The geometry of the study location is highlighted, saved and run, and a raster imagery file of the study area is generated after the task has been completed with a 'projection and extent' in the Geographic Tagged Image File Format (.

Background: COVID-19 patients exhibit higher incidence of thrombosis in arteries and veins, including those in lungs. Vasa vasorum, which support large blood vessels, have shown involvement in these pathologic processes.

Methods: To further explore the extent of microvascular damage caused by COVID-19 infection, we examined resected main, right, or left pulmonary artery specimens from patients undergoing bilateral lung transplantation for COVID-19- or non-COVID-19-induced pulmonary fibrosis compared with organ donors by histologic and immunohistologic analyses.

Human adenovirus is an infectious agent that causes respiratory infections in adults and children. It has been found that immunocompromised children are highly susceptible to this pathogen, as it can swiftly evolve into severe pneumonia with multiple sequelae. Due to the lack of immunity in children, the body's response mechanisms to innate and acquired immunity are specialized.

Car accidents, infections caused by bacteria or viruses, metastatic lesions, tumors, and malignancies are the most frequent causes of chest wall damage, leading to the removal of the affected area. After excision, artificial bone or synthetic materials are used in chest wall reconstruction to restore the skeletal structure of the chest. Chest implants have traditionally been made from metallic materials like titanium alloys due to their biocompatibility and durability.

Purpose: This study focused on combining irinotecan with Poly (ADP-ribose) polymerase (PARP) inhibitors to explore the potential for novel combination therapeutics in small cell lung cancer (SCLC).

Materials And Methods: We selected 10 different SCLC cell lines with diverse mutational backgrounds in DNA damage response (DDR) pathway genes to evaluate the efficacy of the combination of three PARP inhibitors and irinotecan. After the cells were exposed to the drugs for seven days, cell viability was measured, and a combination index was calculated.
