SUMMARY This paper reviews current mathematical models of sphincters and compares them with a new spatial neuromuscular control model based on known physiological properties. Almost all the sphincter models reviewed were constructed as a component of

A compartmental model of motoneurons of Onuf 's nucleus, the external urethral and anal sphincter motor nucleus, was constructed from morphological and electrophysiological data previously reported in the literature. The model neurons have active som

Publikováno v: Magnetic Resonance Imaging. 17:47-57

In this study, a T1-weighted three-dimensional (3D) spoiled gradient-echo scanning protocol was developed to image the complete arterial system of the pelvis and both legs along their entire length in patients with peripheral arterial disease. Three

In this study a semi-automated and observer-independent algorithm for quantifying post-stenotic signal loss (PSL) in 3D phase-contrast (PC) magnetic resonance angiography (MRA) of patients with renal artery stenosis is presented. This algorithm was d

Lung sounds during allergen-induced asthmatic responses in patients with asthma

Autor: Peter J. Sterk, Zuzana Diamant, J. Vanderschoot, Aeilko H. Zwinderman, Henk J. W. Schreur, Joop H. Dijkman

Publikováno v: American journal of respiratory and critical care medicine, 153(5), 1474-1480. American Thoracic Society

We postulated that the distinct pathophysiologic mechanisms of airway narrowing during the early (EAR) and the late (LAR) asthmatic responses to inhaled allergens are reflected by the generation or transmission of lung sounds in asthma. Therefore, we

A biomechanical model of the lower urinary tract which is able to respond to input signals from a neural network is presented. The neural input is the starting point in the description of the relationships between the various physical parameters in t

AR (q, v) Modeling of Normal Lung Sounds

Autor: H. J. W. Schreur, J. Vanderschoot

Publikováno v: Methods of Information in Medicine. 33:24-27

A model for the dependence of normal lung sounds upon airflow and air volume recorded at the mouth, is proposed and investigated. Data from 8 healthy subjects and 2 sessions have been analysed. Test statistics give very strong support for the adequac

Abnormal lung sounds in patients with asthma during episodes with normal lung function

Autor: J. Vanderschoot, Aeilko H. Zwinderman, Peter J. Sterk, Joop H. Dijkman, Henk J. W. Schreur

Publikováno v: Chest, 106(1), 91-99. American College of Chest Physicians

Even in patients with clinically stable asthma with normal lung function, the airways are characterized by inflammatory changes, including mucosal swelling. In order to investigate whether lung sounds can distinguish these subjects from normal subjec
