The mechanisms by which physical forces regulate endothelial cells to determine the complexities of vascular structure and function are enigmatic. Studies of sensory neurons have suggested Piezo proteins as subunits of Ca(2+)-permeable non-selective cationic channels for detection of noxious mechanical impact. Here we show Piezo1 (Fam38a) channels as(More)
This paper discusses quality metrics as well as procedure for parameters optimization and model assessment for human activity recognition based on sensors signals. We compare micro and macro performance measures in multiclass classification as well as various cross-validation techniques. The paper introduces general concept of Dual(More)
As characterization of glycosylation is required for the licensing of recombinant glycoprotein therapeutics, technique comparability must be assessed. Eleven UK laboratories (seven industrial, two regulatory or government, two academic) participated in an inter-laboratory study to analyze N-glycans present in four mixtures prepared by PNGase F cleavage of(More)
Vascular smooth muscle cells (SMC) are central to arterial structure and function yet their involvement in the progression of abdominal aortic aneurysm (AAA) disease is not well studied. The progressive and silent nature of AAA in man essentially restricts research to the use of “end-stage” tissue recovered during surgical repair. This study aimed to(More)
BACKGROUND Abdominal aortic aneurysm (AAA) growth is a complex process that is incompletely understood. Significant heterogeneity in growth trajectories between patients has led to difficulties in accurately modeling aneurysm growth across cohorts of patients. We set out to compare four models of aneurysm growth commonly used in the literature and confirm(More)
RATIONALE Abdominal aortic aneurysm (AAA) is a complex disease with both genetic and environmental risk factors. Together, 6 previously identified risk loci only explain a small proportion of the heritability of AAA. OBJECTIVE To identify additional AAA risk loci using data from all available genome-wide association studies. METHODS AND RESULTS Through(More)
OBJECTIVE Vascular endothelial growth factor (VEGF) acts, in part, by triggering calcium ion (Ca(2+)) entry. Here, we sought understanding of a Synta66-resistant Ca(2+) entry pathway activated by VEGF. APPROACH AND RESULTS Measurement of intracellular Ca(2+) in human umbilical vein endothelial cells detected a Synta66-resistant component of VEGF-activated(More)
The concentration of free cytosolic Ca2+ and the voltage across the plasma membrane are major determinants of cell function. Ca2+-permeable non-selective cationic channels are known to regulate these parameters but understanding of these channels remains inadequate. Here we focus on Transient Receptor Potential Canonical 4 and 5 proteins (TRPC4 and TRPC5)(More)
