Timing of First Recurrence of Syncope Predicts Syncopal Frequency After a Positive Tilt Table Test Result

, 1997
Objectives. This study sought to determine whether the time to first recurrence of syncope after a positive isoproterenol–tilt table test result accurately predicts the eventual frequency of syncope.Background.

Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

FEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

FEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Effects of age on outcome of tilt-table testing

The American Journal of Cardiology, 1999
Although neurally mediated syncope is thought to be common in the young and rare in the elderly, there are few data evaluating the effects of age on the outcome of tilt-table testing (TTT), especially in patients aged > or =80 years. We examined the results of TTT in 352 subjects with unexplained syncope including 133 patients >65 years of age and 43 ...

Periosteal pressure sensitivity of the chest bone as a measure for autonomic function in ischemic heart disease

Frontiers in Neuroscience
PurposeIn 177 patients with ischemic heart disease and elevated periosteal pain sensitivity of the chest bone indicative of autonomic nervous system dysfunction, we test the hypotheses, (i) there is an association between the tilt table responses for the

Pulsed Wave Doppler Ultrasound Is Useful to Assess Vasomotor Response in Patients with Multiple System Atrophy and Well Correlated with Tilt Table Study

The Scientific World Journal, 2012
The study aim was to assess sympathetic vasomotor response (SVR) by using pulsed wave Doppler (PWD) ultrasound in patients with multiple system atrophy (MSA) and correlate with the tilt table study.

Tilt table testing, methodology and practical insights for the clinic

Clinical Physiology and Functional Imaging, 2023
AbstractTilt table testing (TTT) has been used for decades to study short‐term blood pressure (BP) and heart rate regulation during orthostatic challenges. TTT provokes vasovagal reflex in many syncope patients as a background of widespread use.

Septin 9 PB domains coordinate centrosome positioning and microtubule acetylation to control epithelial polarity

FEBS Letters, EarlyView.
Septin 9 polybasic domains couple phosphoinositide‐rich membrane binding to centrosome positioning, Golgi organization, and microtubule acetylation to control epithelial polarity. Their loss disrupts this axis, causing centrosome mispositioning, Golgi fragmentation, reduced microtubule acetylation, and polarity inversion via upregulation of the ...
