Balloon Pulmonary Angioplasty with Stent Implantation as a Treatment of Proximal Chronic Thromboembolic Pulmonary Hypertension

Diagnostics, 2020
We present a case of a 67-year-old female with proximal chronic thromboembolic pulmonary hypertension (CTEPH), disqualified from pulmonary endarterectomy due to multiple comorbidities and high risk-to-benefit ratio as assessed by multidisciplinary CTEPH ...

Tromethamine improves mucociliary clearance in cystic fibrosis pigs

Physiological Reports, 2022
In cystic fibrosis (CF), the loss of cystic fibrosis transmembrane conductance regulator (CFTR) mediated Cl− and HCO3− secretion across the epithelium acidifies the airway surface liquid (ASL). Acidic ASL alters two key host defense mechanisms: Rapid ASL

An Analytical Study of Fire Out of Battery Using Magneto Rheological Dampers

Shock and Vibration, 2002
The application of magneto rheological dampers for controlling the dynamics of a fire out-of-battery recoil system is examined, using a dynamic simulation of a 105mm cannon. Upon providing a brief background on MR dampers and fire out-of-battery dynamics,

Improved background subtraction and a fresh look at jet sub-structure in JEWEL

European Physical Journal C: Particles and Fields, 2022
Interactions of hard partons in the Quark Gluon Plasma (QGP) created with relativistic heavy ion collisions lead to characteristic modifications of the internal structure of reconstructed jets. A large part of the observed jet sub-structure modifications
