In Vitro Hemocompatibility of the BiVACOR Total Artificial Heart in Continuous and Pulsatile Flow
Artificial Organs, EarlyView.BiVACOR's total artificial heart generates remarkably similar hemocompatibility when operated with a pulse or during continuous flow. Under both conditions, hemolysis and von Willebrand Factor multimers were similar to a commercial reference device after 6 h in vitro evaluation.

Hydraulic In Vitro Characterization of MR‐Conditional Blood Pumps
Artificial Organs, EarlyView.Cardiac surgery in neonates requires close placement of cardiopulmonary bypass machines due to limited blood volume, complicating MR compatibility. This study introduces three MR‐conditional blood pump prototypes. None interfered with MRI imaging, though RF‐related sensor effects remain untested.

Artificial Organs, EarlyView.Multicenter real‐world cohort (n = 327) comparing LVADs: HeartMate 3 (HM3), HeartMate II (HMII), and HeartWare (HVAD). HM3 showed superior long‐term survival versus legacy devices, driven by fewer hemocompatibility‐related adverse events, especially pump thrombosis and ischemic stroke, while major bleeding was similar across devices.

British Journal of Pharmacology, EarlyView.Abstract Background and Purpose Guanylate cyclase‐C (GC‐C) is the receptor for endogenous (uro)guanylin peptides, bacterial toxins and pharmacological analogues. Receptor activation leads to intestinal fluid loss, but also activates an antiproliferative pathway and is a promising target in colorectal cancer therapy.
