Associations of Head-Down Tilt with chemical compounds

  • With the needle left in place and the patient in the Trendelenburg position, the contrast agent is sequentially displaced above any encountered extradural blocks by further injection of diluent or sterile saline into the caudal thecal sac [23].
  • Materials and Methods: Plasma epinephrine and norepinephrine were evaluated in 29 patients who underwent laparoscopic retroperitoneal surgery in a half lateral decubitus position (group 1) or laparoscopic varicocelectomy in a Trendelenburg position (group 2) [24].
  • We studied healthy humans under three separate conditions: control, acute 10 degrees head-down tilt (HDT), and saline infusion (SAL) [25].
  • After 1 and 2 weeks of suspension in an antiorthostatic (head-down tilt) position, the mice were challenged with polyriboinosinic-polyribocytidylic acid to induce interferon-alpha/beta [26].
  • We measured renal functions and hormones associated with fluid regulation after a bolus injection of aldosterone (Ald) during head-down tilt (HDT) bed rest to test the hypothesis that exposure to simulated microgravity altered renal responsiveness to Ald [27].
 

Gene context of Head-Down Tilt

  • Effects of head-down tilt on atrial natriuretic peptide and the renin system in pregnancy [28].
  • Modifications of plasma levels of tissue factor pathway inhibitor and endothelin-1 induced by a reverse Trendelenburg position: influence of elastic compression--preliminary results [29].
  • Twenty-four men (31 +/- 3 yr) underwent 5 d of 6 degree head-down tilt: eight performed no exercise (CON), eight performed upright treadmill exercise (UPex), and eight performed supine treadmill exercise against LBNP at -51.3 +/- 0.4 mm Hg (LBNPex) [30].
  • A head-down tilt on the other side induces central engorgement leading to a decrease of EPO concentrations [31].
  • Alternative experimental models conducted to simulate the effects of weightlessness in humans such as head-down tilt (HDT) and lower body positive pressure (LBPP) have yielded less consistent results than those of water immersion (WI) with respect to renal function [32].
