Abstract: The present disclosure discloses a method for preparing lipase with high ester synthesis activity by using surfactant, belonging to the field of enzyme engineering. The present disclosure provides a method for obtaining a lipase with high ester synthesis activity by adding different surfactants with different concentrations in a lipase aqueous solution and then freeze-drying. The lipase meets the requirement in non-aqueous catalysis. Mixing a variety of lipase with no ester synthesis activity or low activity at suitable concentration and an appropriate concentration of the surfactant in the solution can produces lipases with significantly improved ester synthesis activity, meanwhile changing the hydrolytic activity of the lipase. Increased ester synthesis activity makes lipase more suitable for industrial applications.

Abstract: In respiratory monitoring, a breathing cycle detector (44) detects a breath interval in airway pressure and/or flow data. A respiratory parameters estimator and validator (30) asynchronously fits the airway pressure and airway flow data to an equation of motion of the lungs relating airway pressure and airway flow to generate asynchronously estimated respiratory parameters for the breath interval, using a sliding time window that is not synchronized with the breath interval. The asynchronously estimated respiratory parameters for the breath interval are validated using at least one physiological plausibility criterion defined with respect to the breath interval. Responsive to failure of the validation, the airway pressure and airway flow data are synchronously fitted to the equation of motion of the lungs to generate synchronously estimated respiratory parameters for the breath interval. The synchronous fitting is performed in a time window aligned with the breath interval.

Abstract: Respiratory variables are estimated on a per-breath basis from airway pressure and flow data acquired by airway pressure and flow sensors (20, 22). A breath detector (28) detects a breath interval. A per-breath respiratory variables estimator (30) fits the airway pressure and flow data over the detected breath interval to an equation of motion of the lungs relating airway pressure, airway flow, and a single-breath parameterized respiratory muscle pressure profile (40, 42) to generate optimized parameter values for the single-breath parameterized respiratory muscle pressure profile. Respiratory muscle pressure is estimated as a function of time over the detected breath interval as the single-breath parameterized respiratory muscle pressure profile with the optimized parameter values, and may for example be displayed as a trend line on a display device (26, 36) or integrated (32) to generate Work of Breathing (WoB) for use in adjusting settings of a ventilator (10).
