Annals of Thoracic Surgery, 1997 BACKGROUND: The inflammatory response induced by cardiopulmonary bypass can result in severe organ dysfunction in some patients. This postperfusion response is caused mainly by contact between blood and the foreign surface of the cardiopulmonary bypass ...

Fish Passage and Injury Risk at a Surface Bypass of a Small-Scale Hydropower Plant
Sustainability, 2019 In contrast to the efforts made to develop functioning fishways for upstream migrants, the need for effective downstream migration facilities has long been underestimated.

Effects of Graphite Surface Roughness on Bypass Flow Computations for an HTGR [PDF]
Volume 5: High-Pressure Technology; Nondestructive Evaluation; Nuclear Engineering, 2011 Bypass flow in a prismatic high temperature gas reactor (HTGR) occurs between graphite blocks as they sit side by side in the core. Bypass flow is not intentionally designed to occur in the reactor, but is present because of tolerances in manufacture, imperfect installation and expansion and shrinkage of the blocks from heating and irradiation.

Down-regulation of surface monocyte lipopolysaccharide-receptor cd14 in patients on cardiopulmonary bypass undergoing aorta-coronary bypass operation [PDF]
The Journal of Thoracic and Cardiovascular Surgery, 1998 Major operative trauma like aorta-coronary bypass operation may lead to postoperative immunodisturbance, putting the patient at an increased risk for infection and sepsis. The monocyte/macrophage system and the endotoxin receptor CD14 are important in the early recognition and elimination of invading bacteria.

Modulation of platelet surface adhesion receptors during cardiopulmonary bypass.
Anesthesiology, 1991 Alterations in platelet receptors critical to adhesion may play a role in the pathogenesis of the qualitative platelet defect associated with cardiopulmonary bypass. Using flow cytometry, we measured changes in the following platelet surface adhesive proteins: the von Willebrand factor receptor, glycoprotein Ib; the fibrinogen receptor, glycoprotein ...

Surface-bound heparin fails to reduce thrombin formation during clinical cardiopulmonary bypass.
Journal of Thoracic and Cardiovascular Surgery, 1996 The hypothesis that heparin-coated perfusion circuits reduce thrombin formation and activity; fibrinolysis; and platelet, complement, and neutrophil activation was tested in 20 consecutive, randomized adults who had cardiopulmonary bypass.

From bypass transition to flow control and data-driven turbulence modeling: An input-output viewpoint [PDF]
Annual Review of Fluid Mechanics, 2020 Transient growth and resolvent analyses are routinely used to assess nonasymptotic properties of fluid flows. In particular, resolvent analysis can be interpreted as a special case of viewing flow dynamics as an open system in which free-stream ...

DNA surface exploration and operator bypassing during target search [PDF]
Nature, 2020 Many proteins that bind specific DNA sequences search the genome by combining three-dimensional diffusion with one-dimensional sliding on nonspecific DNA1-5. Here we combine resonance energy transfer and fluorescence correlation measurements to characterize how individual lac repressor (LacI) molecules explore the DNA surface during the one-dimensional

Nature Communications, 2022 Some misfolded protein conformations can bypass proteostasis machinery and remain soluble in vivo. This is an unexpected observation, as cellular quality control mechanisms should remove misfolded proteins.

Adaptations in gastrointestinal physiology after sleeve gastrectomy and Roux-en-Y gastric bypass.
The Lancet Gastroenterology and Hepatology, 2021 Linked to the growing obesity epidemic, demand for bariatric and metabolic surgery has increased, the most common procedures being sleeve gastrectomy and Roux-en-Y gastric bypass.
