Impact of competitive flow on wall shear stress in coronary surgery: computational fluid dynamics of a LIMA-LAD model [PDF]
Competitive flow from native coronary vessels is considered a major factor in the failure of coronary bypass grafts. However, the pathophysiological effects are not fully understood.

Wireless blood pressure sensor implantation in sheep: A detailed technique
Twelve adult sheep underwent wireless blood pressure sensor implantation. The procedure lasted an average of 36 min, with mean systolic and diastolic blood pressures of 93 ± 6 and 65 ± 5 mmHg, respectively. This rapid, minimally invasive protocol is a powerful platform for cardiovascular device development.

Computer simulation of platelet activation in a pulsatile ventricular assist device, through finite elements and a simplified geometry [PDF]
Ventricular assist devices are a technological solution for patients who suffer from cardiac insufficiency and await a transplant. In this work, a new design of an implantable pulsatile blood pump is analyzed in terms of blood damage, by means of finite ...

Spatial model of convective solute transport in brain extracellular space does not support a "glymphatic" mechanism. [PDF]
A "glymphatic system," which involves convective fluid transport from para-arterial to paravenous cerebrospinal fluid through brain extracellular space (ECS), has been proposed to account for solute clearance in brain, and aquaporin-4 water channels in ...

Porcine kidney xenotransplantation: From primate models to clinical reality
In the face of a critical shortage of human donor kidneys for end‐stage renal disease patients, porcine kidney xenotransplantation has emerged as a viable solution. This field has navigated major hurdles, including immune rejection, physiological incompatibilities, potential biomechanical differences and the risk of cross‐species infection. To overcome
