Advanced Functional Materials, EarlyView.MAGTWIST: A compact magnetic rotary actuator, enabling smooth, stepless rotation, and on‐demand locking. Inspired by peristalsis, a soft polymer belt generates a traveling‐wave, enabling 270° rotation when heated. Cooling stiffens the belt, locking it in position and enabling it to withstand high loads.

Acute kidney injury is associated with a decrease in cortical renal perfusion during septic shock
Critical Care, 2018 BackgroundRenal perfusion status remains poorly studied at the bedside during septic shock. We sought to measure cortical renal perfusion in patients with septic shock during their first 3 days of care using renal contrast enhanced ultrasound (CEUS ...

Drug‐Free Thrombolysis Mediated by Physically Activated Micro/Nanoparticles
Advanced Functional Materials, EarlyView.Overview of particle‐mediated thrombolytic effects (thermal, mechanical, and chemical) and their activating physical stimuli (light, ultrasound, and magnetic field) in drug‐free thrombolysis. ABSTRACT Thrombus‐associated disorders rank among the world's leading causes of death, with ischemic heart disease and stroke as the main contributors.

Whole-mount imaging of the mouse hindlimb vasculature using the lipophilic carbocyanine dye DiI.
BioTechniques, 2012 The availability of transgenic disease backgrounds and the accessibility of molecular research reagents have contributed to make the mouse ischemic hindlimb the model of choice for many studies of angiogenesis, and to investigate new treatments for ...

Advanced Functional Materials, EarlyView.ABSTRACT Engineering living matter has great clinical potential to deliver functional replacement organs. However, clinical translation remains hampered by the current inability to maintain viability of clinically relevant‐sized constructs. During the pre‐vascular phase, implants rely on nutrient diffusion for survival, which is insufficient at ...

Cell Calcification Models and Their Implications for Medicine and Biomaterial Research
Advanced Healthcare Materials, EarlyView.Calcification, is the process by which the tissues containing minerals are formed, occurring during normal physiological processes, or in pathological conditions. Here, it is aimed to give a comprehensive overview of the range of cell models available, and the approaches taken by these models, highlighting when and how methodological divergences arise,
