Forced oscillation technique for optimising PEEP in ventilated extremely preterm infants [PDF]
European Respiratory Journal, 2020 Ventilatory settings are critical in mechanically ventilated extremely preterm newborn infants due to the risk of ventilation induced lung injury (VILI) and subsequent development of bronchopulmonary dysplasia (BPD) [1]. The positive end-expiratory pressure (PEEP) settings usually rely on blood gases, oxygen requirement, lung auscultation, evaluation ...

Northern Hemisphere interdecadal variability: A coupled air-sea mode [PDF]
, 1998 A coupled air–sea mode in the Northern Hemisphere with a period of about 35 years is described. The mode was derived from a multicentury integration with a coupled ocean–atmosphere general circulation model and involves interactions of the thermohaline ...

Interval Oscillation Criteria for Second-Order Forced Functional Dynamic Equations on Time Scales
Discrete Dynamics in Nature and Society, 2014 This paper is concerned with oscillation of second-order forced functional dynamic equations of the form (r(t)(xΔ(t))γ)Δ+∑i=0nqi(t)|x(δi(t))|αisgn x(δi(t))=e(t) on time scales. By using a generalized Riccati technique and integral averaging techniques,

Guanylyl cyclase activation reverses resistive breathing–induced lung injury and inflammation [PDF]
, 2015 Inspiratory resistive breathing (RB), encountered in obstructive lung diseases, induces lung injury. The soluble guanylyl cyclase (sGC)/cyclic guanosine monophosphate (cGMP) pathway is down-regulated in chronic and acute animal models of RB, such as ...
