Dynamic fluid shifts induced by fetal bypass

Glycerol-induced fluid shifts attenuate the vestibulosympathetic reflex in humans.

The glycerol dehydration test (GDT) has been used to test for the presence of Ménière's disease and elicits acute alterations in vestibular reflexes in both normal and pathological states. Activation of the vestibulosympathetic reflex (VSR) increases muscle sympathetic nerve activity (MSNA) and peripheral vascular resistance. We hypothesized that the GDT would attenuate the VSR through fluid sh...

Fluid shifts in anaphylaxis

We read the interesting article of Dr Iannuzzi and colleagues [1] and would like to illustrate the extent of fluid shifts induced by anaphylaxis, the necessity of volume support and catecholamine therapy. A 35-yr-old male (ASA I) presented for elective operation of the paranasal sinuses. Five minutes after induction of anaesthesia with propofol (200 mg), fentanyl (0.3 mg) and rocuronium (40 mg)...

Fluid-Induced Nonlinear Dynamic Tensioning of Cables

The long-term goal of this research is to identify the dominant mechanisms that control the dynamic tension in submerged cables. This goal addresses the need to suppress or alleviate the dynamic component of cable tension that may adversely affect the performance of underwater cables and any mission they are used to support. For instance, large dynamic tension forces may degrade the positioning...

Radiative energy shifts induced by local potentials

We study a specific correction to the Bethe logarithm induced by potentials which are proportional to a Dirac-δ function in coordinate space (“local potentials”). Corrections of this type occur naturally in the calculation of various self-energy corrections to the energy of bound states. Examples include logarithmic higher-order binding corrections to the two-loop self-energy, vacuum-polarizati...
