Respect versus resect approaches for mitral valve repair: A study-level meta-analysis.

Mitral valve repair (MVr) restores leaflets coaptation while preserving the patient's own valve. The two main techniques are: (a) chordal replacement ("respect approach"), whereby artificial neochordae are used to resuspend prolapsed segments of the affected leaflet - and (b) leaflet resection ("resect approach"), whereby diseased leaflet segment is resected, and the remaining segments are sutured together. Both techniques of MVr are associated with better long-term results, fewer valve-related complications and lower mortality when compared with mitral valve replacement (MVR).

The effect of rigid cells on blood viscosity: linking rheology and sickle cell anemia.

Sickle cell anemia (SCA) is a disease that affects red blood cells (RBCs). Healthy RBCs are highly deformable objects that under flow can penetrate blood capillaries smaller than their typical size. In SCA there is an impaired deformability of some cells, which are much stiffer and with a different shape than healthy cells, and thereby affect regular blood flow.

Influence of Salt on the Viscosity of Polyelectrolyte Solutions.

Polyelectrolytes (PEs) are charged polymers in polar solvents. Classical scaling theories suggest that the viscosity η for semidilute unentangled PE solutions in θ solvents obeys the empirical Fuoss law η∝n_{p}^{1/2} in the "salt-free" regime, and η∝n_{p}^{5/4} in the regime affected by added salt, where the polymer concentration n_{p} is defined as the number of monomers per volume. However, recent experiments have also reported η∝n_{p}^{0.
