THE GLYMPHATIC SYSTEM AND AMYOTROPHIC LATERAL SCLEROSIS.

Progress in neurobiology
The glymphatic system and the meningeal lymphatic vessels provide a pathway for transport of solutes and clearance of toxic material from the brain. Of specific relevance to ALS, this is applicable for TDP-43 and glutamate, both major elements in disease

Analysis of Influence of Lateral Free Clearance of Axle Box Bearings on Heavy Haul Locomotive

ICTIS 2011, 2011
To ensure the safe running of locomotives a dynamics computing model 25T axle load C0-C0 axis dynamic model of heavy haul locomotive is established in this paper with the multi-rigid-body dynamics analysis software Simpack. Influence of lateral free clearance of intermediate axle box bearings on the stability of straight running , curve passing ...

Radial pressure distribution in lateral clearances of the semi-open axiradial impeller of the centrifugal compressor

Russian Aeronautics (Iz VUZ), 2012
We present the results of the numerical simulation of a flow and radial pressure distribution in the lateral clearances of the semi-open axiradial impeller of the centrifugal compressor with the use of the FlowVision and Fluent software. The results of the numerical analysis were compared with the known experimental data.

[Techniques favoring airway clearance in patients with amyotrophic lateral sclerosis].

Revue neurologique, 2007
Although noninvasive ventilation may improve survival in patients with amyotrophic lateral sclerosis (ALS), ineffective airway clearance is an important cause of therapeutic failure. We report in this paper the main studies which have assessed assisted cough techniques in patients with ALS.

Stydying the Flow Field Inside Lateral Clearances of External Gear Pumps

2004
In this paper the flow field in the clearances bounded by gears lateral sides and bearing blocks internal surfaces of external gear pumps is studied. Firstly, the pressure distribution is determined applying the Laplace equation to the domain limited by two successive teeth profiles, the middle lines of the first and of the last space and the drain ...

Metabolic clearance rate of dehydroisoandrosterone sulfate. VII. Effect of lateral versus supine recumbency.

Obstetrics and gynecology, 1976
The physiologic events which may occur with the gravid women in the supine position suggest that uteroplacental blood flow may be impaired as a consequence of decreased venous return to the heart and the resulting decrease in cardiac output. Since the metabolic clearance rate of dehydroisoandrosterone sulfate (MCRDS) previously has been shown to ...
