Vaso-constriction following deep inspiration

Impaired response to deep inspiration in obesity.

Deep inspirations modulate airway caliber and airway closure and their effects are impaired in asthma. The association between asthma and obesity raises the question whether the deep inspiration (DI) effect is also impaired in the latter condition. We assessed the DI effects in obese and nonobese nonasthmatics. Thirty-six subjects (17 obese, 19 nonobese) underwent routine methacholine (Mch) cha...

Deep Unfolding: Model-Based Inspiration of Novel Deep Architectures

Model-based methods and deep neural networks have both been tremendously successful paradigms in machine learning. In model-based methods, we can easily express our problem domain knowledge in the constraints of the model at the expense of difficulties during inference. Deterministic deep neural networks are constructed in such a way that inference is straightforward, but we sacrifice the abili...

Airway re-narrowing following deep inspiration in asthmatic and nonasthmatic subjects.

After bronchoconstriction, deep inspiration (DI) causes dilatation followed by airway re-narrowing. Re-narrowing may be faster in asthmatic than nonasthmatic subjects. This study investigated the relationship between re-narrowing and the magnitude of both DI-induced dilatation and the volume-dependence of respiratory system resistance (Rrs) during tidal breathing. In 25 asthmatic and 18 nonasth...

Proteinuria following Momentary Vascular Constriction.

The Production of Albuminuria by Renal Vaso- Constriction in Animals and in Man. by Isaac Starr,

The production of albuminuria 1 as the result of obstruction or interruption of blood flow through the kidney by compression of the renal artery was first demonstrated by Hermann (1). Subsequent work has shown that the glomerulus is the structure in which the escape of albumin in this condition takes place (2). Evidence that interruptions occur spontaneously in the circulation through individua...
