  • cerebral
  • We evaluated time courses of cerebral blood flow, apparent diffusion coefficient (ADC), T1, T2, accuracy of infarct prediction strategies, and impact on statistical evaluation of experimental stroke studies. (ahajournals.org)
  • The incidence of a new onset postoperative cerebral ischemia [ Time Frame: participants will be followed for the duration of hospital stay, an expected average of 3 weeks. (clinicaltrials.gov)
  • cerebral ischemia is diagnosed by clinical symptoms and radiologic imaging (CT or MRI). (clinicaltrials.gov)
  • We performed a direct, longitudinal, morphological comparison of 1 H T2 relaxation, 1 H apparent diffusion coefficient (ADC), 23 Na content, and histopathology after cerebral ischemia to address the hypotheses that (a) 23 Na MRI is unique in comparison to 1 H MRI, and (b) accumulation of 23 Na is an unambiguous marker for dead tissue. (ahajournals.org)
  • In this study, we used a rat model of focal cerebral ischemia and performed a direct, longitudinal, morphological comparison between estimated 1 H T2 maps, estimated 1 H ADC maps, 23 Na images, and triphenyltetrazolium chloride (TTC)-stained sections. (ahajournals.org)
  • ischemic
  • A retrospective analysis of 1031 patients with STEMI referred for primary percutaneous coronary intervention with known ischemic times between 1 and 6 hours identified 165 patients with occluded arteries on presentation without evidence of preinfarction angina or collateral blood flow. (ahajournals.org)
  • Plasma levels of hepatocyte growth factor (HGF) are increased within hours of cardiac ischemia/reperfusion in rats, and HGF has been shown to be cardioprotective toward acute ischemic injury. (aspetjournals.org)
  • Imaging studies of stroke often test new techniques for their ability to (a) reveal the location and extent of ischemic injury at early time points and (b) quantify the degree of damage that has occurred or may subsequently develop. (ahajournals.org)
  • donor
  • The aim of this study was to investigate two methods of hand assistance and kidney removal during HALDN and their effect on the time it takes for the donor to return to normal physical activity. (springer.com)
  • Length of hospital stay, physical activity score, time to return to work, donor satisfaction, cosmetic score, postoperative complications, and all-cause mortality in living donors will also be reported. (springer.com)
  • This is the first randomized controlled trial to compare the time it takes the living donor to return to normal physical activity after HALDN using two different types of incision. (springer.com)
  • transient
  • Several models of transient retinal ischemia have been reported and include techniques that increase intraocular pressure (IOP) to higher than the systolic arterial blood pressure 3 4 5 or ligate the optic nerve with the central retinal artery (CRA). (arvojournals.org)
  • Therefore, using 12-lead ECG monitoring, the COMPARE Study (electro C ardiographic evaluati O n of ische M ia com P aring inv A sive to pha R macological tr E atment) was designed to assess the frequency and clinical consequences of transient myocardial ischemia, in patients with NSTEMI/UA treated with either early invasive PCI/stent or those managed conservatively (medications or PCI/stent following recurrent symptoms).

  • Tissue
  • [ 3 ] Time wasted attempting to arrange for imaging studies, laboratory testing, or other diagnostic procedures results in the loss of testicular tissue. (medscape.com)
  • In order to compensate for the ischemia, there is vasoconstriction of mesenteric vessels resulting in increased tissue oxygen extraction along with vasodilation of the collateral vessels. (wikidoc.org)
  • On this time scale, despite the low 23 Na MR sensitivity and low mean Na + tissue concentration, we could readily acquire 23 Na images at an adequate temporal and spatial resolution. (ahajournals.org)
  • responses
  • Mesenteric ischemia occurs when intestinal blood supply is compromised by more than 50% of the original blood flow without activation of adaptive responses. (wikidoc.org)
  • protein
  • However, this technique requires a large sample volume, has a small dynamic range, and can measure only one protein at a time. (jove.com)
  • baseline
  • Trough exercise duration increased by 115.6 seconds from baseline in both ranolazine groups (pooled) vs 91.7 seconds in the placebo group (P =.01). (nih.gov)
  • The width of the vulnerable window increased from 25 ± 22 ms during baseline to 75 ± 26 ms during ischemia (p = 0.001). (onlinejacc.org)
  • The upper limit of vulnerability (baseline vs. ischemia: 294 ± 44 vs. 274 ± 53 V, p = 0.21) and the defibrillation threshold (271 ± 33 vs. 268 ± 42 V, p = 0.74) remained unchanged during ischemia. (onlinejacc.org)
