TL;DR: The Transonic flowmeter displayed a lower PI than the MediStim, due to a lower filter setting, while in the Transonic,flow signals are filtered at a lower level, rendering a 'smoother' pattern of flow curves.

Intraoperative graft verification in coronary surgery.
TL;DR: High-resolution epicardic coronary ultrasound module has been added to graft flow evaluation providing 2D ultrasound imaging (either in short-axis or long-axis) and color-flow mapping, allowing an accurate morphological evaluation of body graft and anastomosis.

TL;DR: To the best of the knowledge, this is the first study where blood-flow was directly and simultaneously measured in all the components of the LIMA-to-LAD anastomosis.

TL;DR: Previously reported cut-off values for intraoperative TTFM parameters could not be adapted for the early patency of GEA grafts to the RCA, however, the smoothness of the graft-flow curve may be a reliable predictor of postoperative graft patency.

TL;DR: An high RI value measured intraoperatively in renal allograft artery using transit time flowmetry was a valuable predictor of inferior early and long-term kidney graft function.

Current status of intra-operative graft assessment: Should it be the standard of care for coronary artery bypass graft surgery?
TL;DR: Evidence is examined to support the premise that intra‐operative graft assessment is essential in determining graft patency and should be the standard of care when performing CABG surgery.

- 28 Sep 2004
TL;DR: Physically Based Rendering: From Theory to Implementation, Third Edition, describes both the mathematical theory behind a modern photorealistic rendering system and its practical implementation through a method known as 'literate programming', which serves as an essential resource on physically-based rendering.

Ecosystem services: From theory to implementation
TL;DR: Advances are required on three key fronts, each featured here: the science of ecosystem production functions and service mapping; the design of appropriate finance, policy, and governance systems; and the art of implementing these in diverse biophysical and social contexts.

TL;DR: There were a number of differences between patients with intermittent claudication who had a high blood viscosity and those who did not, and those with an initially high blood Viscosity had a significantly worse prognosis than claudicants with a normal viscosities.

TL;DR: Measurements of intraoperative flow and resistance as well as derived variables allow assessment of early graft function and thus help prevent graft failure and reduce perioperative infarction in patients with coronary artery disease.
