Preoperative pulmonary angiography and evaluation of the pulmonary-to-systemic flow ratio (Qp/Qs) may have use in revealing vascular abnormalities [5, 6]; however, this approach was considered to be unnecessary as long as the abnormal connection between the systemic and pulmonary circulation is identified and surgically excised.
Vessels with functional circulation were identified by an intravascular injection of ink before Zn fixation.
In addition to CEA, several other cell-surface markers known to be shed into the circulation were identified in these studies including: MET (c-Met proto-oncogene product, hepatocyte growth factor receptor) [ 42], mesothelin [ 43], EPCAM [ 44], and ICAM-1 [ 45].
Viral evolutionary dynamics were analyzed, and the effect of vaccination on virus circulation in China was identified.
The carotid artery was identified either by circulation arrest on the Doppler signal of the MCA or, to account for cross flow from the contributors of circle of Willis, more than 30% reduction of the systolic velocity of the middle cerebral artery.
Earlier, the importance of convergence of the meridional circulation over the pole during winter was identified to explain the unusually high wintertime concentrations of Fe and Na at the South Pole.
Thermal conductivity of soil, initial temperature difference between circulation fluid and ground, and radius of the circulation tube are identified as the three most important parameters that control heat transfer through geothermal piles.
In addition, three distinct circulation cycles were identified and their time distribution was quantified.
Following the discovery of the positive CNS effects of infusing young blood into old mice, or of heterochronic parabiosis, multiple individually CNS-active factors in the circulation have been identified.
Optimal ranges of steam pressure and oil circulation rate were identified to maximize heat recovery while maintaining an appropriate oil temperature.
