Background: Cervical artery dissection (CeAD) may result in dissecting aneurysm (DA) formation. We aimed to characterize risk factors and clinical outcomes associated with DA in a large, international CeAD cohort. Methods: We performed a secondary analysis of the Antithrombotic Treatment for Stroke Prevention in Cervical Artery Dissection (STOP-CAD), an international, multicenter, retrospective cohort. Patients with spontaneous CeAD were assessed for DA at baseline and de novo DA formation....

Smoke from agricultural fires is a potentially important source of fine particulate matter (PM(2.5)) in the US. Sugarcane is burned in Florida to facilitate the harvesting process, with the majority of these fires occurring in the Everglades Agricultural Area (EAA), where there is only one regulatory air quality monitor. During the 2022-2023 sugarcane burning season (October-May), we used public low-cost PurpleAir sensors, regulatory monitors, and 29 PurpleAir sensors deployed for this study to...

Metal-free heteroatom-doped carbocatalysts are promising alternatives to precious metals for alkane direct dehydrogenation/hydrogenation and reversible hydrogen storage, yet the nature of their active sites remains poorly understood. This study investigates a nitrogen assembly carbocatalyst (NAC) for efficient and selective hydrocarbon dehydrogenation. For ethylbenzene, NAC maintains a selectivity of >99% towards styrene at a conversion of >20% for 120 hours at a weight hourly space velocity of...

CONCLUSION: This study is the first to analyse SLE-PAH through cluster-based methods. Sm-RNP antibodies indicate more severe disease needing dual therapy, while multiple positive antibodies suggest a better prognosis, with most patients achieving PAH resolution.

Iron is an essential nutrient for almost all organisms. However, excess iron generates reactive oxygen species and causes tissue injuries. Iron is implicated in idiopathic pulmonary fibrosis (IPF). In this study, we examined iron accumulation in fibrotic lung fibroblasts and the underlying mechanisms. We hypothesize that the downregulation of Solute Carrier Family 40 Member 1 (SLC40A1) results in iron accumulation in lung fibroblasts of IPF patients. Using a Prussian Blue iron staining, we found...
