Perylene (PER) is a prototype of polycyclic aromatic hydrocarbons (PAHs), which play a pivotal role in various functional and electronic materials due to favorable molecule-to-molecule overlaps, which enhance electronic transport. This study provides guidelines regarding the impact of molecular charge on pancake bonding, a form of strong π-stacking interaction. Pancake... Read more

BACKGROUND: Recent guidelines for spirometry interpretation recommend both race-neutral reference equations and use of z-score thresholds to define severity of airflow obstruction.... Read more

CONCLUSIONS: DLCO impairment in severe SDB was associated with sleep-related hypoxemia, prevalent hypertension and type 2 diabetes. Assessment of SDB should be considered in those with impaired DLCO to guide testing and risk-stratification strategies.... Read more

CONCLUSIONS: FEV(1)Q is an intuitive and simple race-neutral approach to interpreting FEV(1) that predicts survival better than current alternative methods.... Read more

CONCLUSION: Participant experience is shaped by the instructor-participant relationship, the social environment of classes, and class difficulty level. In order to support participant experience, classes should be safe, supportive, and have an appropriate challenge-skill balance. These qualities facilitate creative immersion and the potential for personal and collective change.... Read more

Indoor sources of air pollution worsen indoor and outdoor air quality. Thus, identifying and reducing indoor pollutant sources would decrease both indoor and outdoor air pollution, benefit public health, and help address the climate crisis. As outdoor sources come under regulatory control, unregulated indoor sources become a rising percentage of... Read more

CONCLUSION: Prior series of patients with brain metastases of multiple histologies have demonstrated an improvement in the local efficacy of stereotactic radiosurgery when combined with systemic agents. We found that patients treated with targeted agents and patients treated with immunotherapy demonstrated a trend towards improvement over patients treated in the... Read more

CONCLUSION: Patients with COPD treated with ICS/LABA during baseline, including patients specifically treated with BUD/FORM and those with a history of ≥ 1 exacerbation, had fewer COPD exacerbations and lower COPD-related HCRU after initiating FF/UMEC/VI.... Read more
