• mmHg
  • The conversion between these units is: 1 mmHG ⋅ min L ( HRUs ) = 8 MPa ⋅ s m 3 = 80 dyn ⋅ sec cm 5 {\displaystyle 1\,{\frac {{\text{mmHG}}\cdot {\text{min}}}{\text{ L }}}({\text{HRUs}})=8\,{\frac {{\text{MPa}}\cdot {\text{s}}}{{\text{m}}^{3}}}=80\,{\frac {{\text{dyn}}\cdot {\text{sec}}}{{\text{cm}}^{5}}}} The basic tenet of calculating resistance is that flow is equal to driving pressure divided by resistance.

  • downstream
  • Recent and accumulating evidence in this area has implicated excessive Ser phosphorylation and proteosomal degradation of the docking protein, insulin receptor substrate, and enhanced signaling through hybrid insulin/IGF-1 receptor as important mechanisms underlying aldosterone-mediated interruption of downstream vascular insulin signaling.

  • 5-8 With Poccl, the pulmonary arterial resistance can be partitioned into larger arterial (upstream) and small arterial plus venous (downstream) components. (ahajournals.org)
  • compliance
  • Vascular compliance is determined by the muscle tone in the smooth muscle tissue of the tunica media and the elasticity of the elastic fibers there, but the muscle tone is subject to continual homeostatic changes by hormones and cell signaling molecules that induce vasodilation and vasoconstriction to keep blood pressure and blood flow within reference ranges. (wikipedia.org)
  • Reversal
  • Due to the potential anti-proliferative and anti-fibrotic activity of terguride, this potential medicine could offer the hope of achieving reversal of pulmonary artery vascular remodeling and attenuation of disease progression. (wikipedia.org)
  • vessel
  • Vasomotion could also be a mechanism of increasing the reactivity of a blood vessel by avoiding the "latch state", a low ATP cycling state of prolonged force generation common in vascular smooth muscle. (wikipedia.org)
  • Units
  • This is numerically equivalent to hybrid resistance units (HRU), also known as Wood units (in honor of Paul Wood, an early pioneer in the field), frequently used by pediatric cardiologists. (wikipedia.org)
  • significant
  • Although there is significant in vitro evidence suggesting that O 2 − contributes to increased systemic vascular tone in the SHR, the role of O 2 − in the increased RVR and MAP of SHR in vivo remains unclear. (ahajournals.org)
  • disease
  • An Early Contributor to Diabetes-Related Vascular Disease? (diabetesjournals.org)
  • Over the past 10 years it has become clear that intact vascular function, especially at the level of the endothelium, is paramount in the prevention or delay of cardiovascular disease. (nih.gov)
  • Raised non-esterified fatty acids impair insulin's effect on glucose uptake in skeletal muscle and the vascular endothelium and thus could have detrimental effects on the vasculature, leading to premature cardiovascular disease. (nih.gov)
  • modulation
  • To determine how in vivo modulation of thiol redox state affects small resistance arteries relaxation, we generated a transgenic mouse strain that overexpresses thioredoxin, a small redox protein (Trx-Tg), and another strain that is thioredoxin-deficient (dnTrx-Tg). (ahajournals.org)
  • time
  • Echocardiographic ratio of peak tricuspid regurgitant velocity to the right ventricular outflow tract time-velocity integral (TRV/TVI rvot) was presented as a reliable non-invasive method of estimating pulmonary vascular resistance (PVR). (7thspace.com)
  • But a trading range isn't fixed and investor attitudes change, so the resistance level tends to move higher or lower over time. (thefreedictionary.com)
  • When patch clamp recordings are conducted, depolarization occurs in the endothlial layer at the same time as the underlying vascular smooth muscle. (wikipedia.org)
  • channels
  • Vascular thiol redox state has been shown to modulate vasodilator functions in large conductance Ca 2+ -activated K + channels and other related channels. (ahajournals.org)
  • Diagram of the vascular channels in a human embryo of the second week. (wikipedia.org)
