At physiologic heart rates, most filling seemed passive (that is, little contribution from atrial contraction was discerned in volume–time tracings). Thus, even small (<1 mm Hg) pressure ...

2010), which encodes vascular smooth muscle α-actin (SM α-actin). Mutations in SM α-actin may profoundly affect its interaction with myosin, other actin protomers within the filament, actin-binding ...

The figure was above market expectations of 48.5 percent, according to Briefing.com, but still below the 50-point mark separating expansion from contraction. "US manufacturing activity contracted ...

This gap formation is based on an actin–nonmuscle myosin contraction process at the margins of the cell. Analogous to smooth muscle cell contraction, phosphorylation of the myosin light chain (MLC) by ...

This protein, found in high levels in both skeletal and cardiac myofibrils, was determined to be >1 MDa in size through analytic ultracentrifugation and gel electrophoresis, using a multimeric myosin ...

In a recent economic event, the Chicago Purchasing Managers' Index (PMI) reported a score of 36.9, suggesting a contraction in the manufacturing sector of the Chicago region. The PMI score of 36.9 ...
