Mechanistic Insights Into How Rewiring and Bifurcation Angle Affect DK‐Crush Stent Deployment

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Double kissing crush (DKC) is a preferred two‐stent technique for complex coronary bifurcation lesions. Proximal cell rewiring is routinely recommended to reduce technical failure, and DKC is considered effective across various bifurcation angles. However, it remains unclear whether this standard approach is optimal for all patients.

Numerical Modeling of Flow in Side Channel Spillway Using ANSYS-CFX

Zanco Journal of Pure and Applied Sciences, 2018
Side channel spillway is one of the most common types of spillways provided at earth dams to release flood discharge laterally. Flow in side channel is complex due to discharge changing along its length.

Mass Exchange Flow Process in Side Channel Pumps: Effects of Different Geometrical Parameters

Energy Science &Engineering, EarlyView.
Figure 1 shows the Mass Flow Exchange (MFE) in the impeller at z = 7.5 × 10−3 m at 1.0 Q/QBEP, operating point for impeller scheme 1 (IMP 1), and impeller scheme 2 (IMP 2). The flow begins to exit the impeller at the outer radius and enters at the inner and central radii. IMP 1 exhibits more flow in and out compared to IMP 2. ABSTRACT The functionality

A noncanonical role for Jagged1 in endothelial mechanotransduction

The FEBS Journal, EarlyView.
This study reveals a noncanonical role for Jagged1 in endothelial mechanotransduction. Shear stress modulates Jagged1 expression and subcellular localization. Loss of Jagged1 attenuates mechanotransduction and reduces Src, VEGFR2, and ERK signaling. Direct mechanical stimulation of Jagged1 induces activation of these signaling pathways.
