Nrf2 reduces allergic asthma in mice through enhanced epithelial cytoprotective function.Asthma is defined as a chronic inflammation of the lower airways and can easily result in bronchoconstriction and even dyspnea.Every year, hundreds of million people around the world suffer from asthma and are unable to work or attend school due to their uncontrolled symptoms. 1 Wheezing is an obvious breathing sound that portrays airflow interference between the lungs and the bronchus and is often considered a primary feature of an acute asthma attack, along with coughing, shortness of breath, and chest tightness. Acute exacerbation or asthma attacks using wheezing sounds have been detected by physicians both with and without stethoscopes. Designs for breathing sound monitoring systems and real-time wheeze detection systems have also been reported. 2 Trubel et al used monofrequent forced oscillation to measure oscillatory airway resistance and calculate variability in order to separate asymptomatic children

Effectiveness of tranexamic acid for improving visual clarity by reducing total coagulation time during arthroscopic rotator cuff repair

“…We previously noticed that electrocautery devices generate a unique sound during coagulation and hypothesized that the total use time of the device can be calculated quantitatively using spectrographic visualization. 12,13 This study aimed (1) to investigate the reliability of electrocautery sound spectrogram visualization and…”
