Modelling of disturbed flow regimes in aspirated pipe systems
… possible "balance" (the distribution of hole flow rates and hence the effective smoke-sensitivity throughout the zone), commensurate with the lowest possible smoke "transport time" (from a hole to the detector). These two objectives are often in conflict. Air flowing into the sampling hole …

X-Box Binding Protein-1 is Important in Maintenance of Endothelial Integrity and Migration
… and Results - Our study demonstrated that disturbed flow upregulated HDACS and XBPlu protein production through the VEGF receptor 2 / PI-3-kinase pathway. Knockdown of XBP1 by shRNA lentiviral transfection ablated disturbed flow-induced HDAC3 upregulation. Similarly to HDACS, overexpression …

Knockdown of Heparan Sulfate Via NDST1 knockout Does Not Inhibit Mouse Aortic Endothelial Cell Alignment In-Vivo
… and bifurcations which are characterized by disturbed flow patterns and the resulting damage and dysfunction to the endothelium. Endothelial cells (ECs) under sustained laminar flow align in the direction of flow; however, under disturbed flow conditions, ECs sustain damage to their …

Predicting Interference Patterns Between Offshore Wind Farms through Wake Analysis
… Placing wind turbines within a field of disturbed flow decreases power output, and in some cases, threatens structural integrity. Unsteady loading and fluxes in wind turbine power generation are born out of turbulence and can further lead to a reduction in the overall energy production of …

Evaluation of Human Umbilical Vein Endothelial Cells in Blood Vessel Mimics Through Changes in Gene Expression and Caspase Activity
… the effect of cell culture duration and flow conditions on endothelial cell gene expression, especially regarding endothelial-to-mesenchymal transition (EndMT). A trend of decreased endothelial marker gene expression and increased mesenchymal marker gene expression would indicate EndMT. …

Endothelial cell plasticity as a marker of vascular disease and predictor of adverse outcomes to stress
… of EC plasticity by shear stress, revealing that flow patterns drive distinct transcriptional signatures and subpopulation behaviors, as demonstrated through singlecell transcriptomics in human aortic endothelial cells. Aim 2 examines the interplay between EC dynamism and antiproliferative drugs, …

Development of a novel in vitro model to study the tryptic : endothelial cells, monocytes and flow
… in vitro model of monocytes transmigration under flow and use in the study of early molecular events of atherogenesis. In this work, we focused on how endothelial dysfunction, specifically mediated by disturbed flow from atherosusceptible regions of the vasculature, is both communicated to …

Fluid Dynamic Assessments of Spiral Flow Induced by Vascular Grafts
… affect endothelial function. Single spiral flow is a normal feature in medium and large sized vessels and it is induced by the anatomical structure and physiological function of the cardiovascular system. Grafts designed to generate a single spiral flow in the distal anastomosis have been …
