Breaking up sitting time after stroke (BUST-Stroke)

International Journal of Stroke, 2016
Rationale Prolonged sitting is associated with an increased risk of cardiovascular and all-cause mortality and morbidity. The metabolic and cardiovascular effects of breaking up sitting time in people with stroke are unknown. Aims and hypotheses

Breaking up sedentary time, physical activity and lipoprotein metabolism

Journal of Science and Medicine in Sport, 2017
Some authors report delayed responses of lipid metabolism after prolonged and interrupted sitting. To date no experimental studies have shown acute physical activity (PA) related changes of lipoprotein metabolism during sedentary behavior (SB). The purpose of this study was to examine immediate effects of a single PA-bout vs.

Reliability of the Tear Break‐Up Time Technique of Assessing Tear Stability and the Locations of the Tear Break‐Up in Hong Kong Chinese

Optometry and Vision Science, 1992
ABSTRACT The measurement of tear break‐up time (TBUT) in assessing stability of the tear film is somewhat controversial, even though the technique is widely used. We examined reliability of the technique within and among examiners and conclude that measurements of TBUT can be made reliably; full‐beam observation of the cornea is ...

The non-invasive tear film break-up time in normal children

British Journal of Ophthalmology, 2013
To perform an objective evaluation of the non-invasive tear break-up time (NITBUT) and lipid layer interferometry in normal children.Children with no known ocular surface disease or anterior segment abnormality were evaluated. We excluded patients with disorders affecting lid margins or tear film composition.

Scaling of the Shaped Charge Jet Break‐Up Time

Propellants, Explosives, Pyrotechnics, 2006
AbstractSince the formula for the shaped charge jet break‐up time was published on 1979 many attempts were made to interpret it and to make its use more efficient. It is shown herein that the Vpl parameter depends on the ratio of the liner thickness to the charge explosive diameter by the formula: 1/Vpl=13.9−101⋅(TL/CD), where TL is the liner thickness,

Adaptive parameter computation for the automatic measure of the Tear Break-Up Time

2012
Dry eye syndrome is a common disorder of the tear film, affecting a significant percentage of the population. The Break-Up Time (BUT) is a clinical test used for the diagnosis of this disease. In this work, we propose several improvements for the automatic computation of the BUT measure that solve the limitations of previous approaches.

[Tear film break-up time with different stains].

Klinische Monatsblatter fur Augenheilkunde, 1983
The tear film break-up time is usually measured with the lacrimal fluid stained with fluorescein. With the staining methods currently recommended the break-up time is difficult to reproduce. In the study described here, the break-up times with different staining methods were compared.
