Saturation of the tilt aftereffect [PDF]
, 1987 The tilt aftereffect increases as a logarithmic function of adapting time, reaches saturation after approx 1 hr and decays on a symmetric, logarithmic time-course.

Influence of passive leg movements on blood circulation on the tilt table in healthy adults
Journal of NeuroEngineering and Rehabilitation, 2004 Background One problem in the mobilization of patients with neurological diseases, such as spinal cord injury, is the circulatory collapse that occurs while changing from supine to vertical position because of the missing venous pump due to paralyzed leg

Effects of Head‐Up Tilt‐Table Test on the QT Interval [PDF]
Annals of Noninvasive Electrocardiology, 2010 Background. The QT interval shortens in response to sympathetic stimulation and its response to epinephrine infusion (in healthy individuals and patients with long QT syndrome) has been thoroughly studied. Head‐up tilt‐table (HUT) testing is an easy way to achieve brisk sympathetic stimulation.

The normal response to prolonged passive head up tilt testing [PDF]
Heart, 2000 OBJECTIVE To define the responses to head up tilt in a large group of normal adult subjects using the most widely employed protocol for tilt testing. METHODS 127 normal subjects aged 19–88 years (mean (SD), 49 (20) years) without a previous history ...

Molecular Oncology, EarlyView.Tumour heterogeneity and clonal evolution of metastatic salivary gland cancer were evaluated in two patients with adenoid carcinoma and one patient with myoepithelial carcinoma. Radiology‐guided autopsy enabled multi‐region sampling (total samples n = 149), followed by whole‐genome sequencing and phylogenetic reconstruction (17 tumour samples, 4–7 per ...

FEBS Open Bio, EarlyView.This protocol paper outlines methods to establish the success of a time‐resolved serial crystallographic experiment, by means of statistical analysis of timepoint data in reciprocal space and models in real space. We show how to amplify the signal from excited states to visualise structural changes in successful experiments.
