Effects of increasing concentrations of TA1 or dobutamine on contractile function, phosphocreatine and ATP concentrations, and ATP production were assessed by 31 P nuclear magnetic resonance ...

Background Contractile reserve, improvement in contractile function during inotropic stimulation, is a proposed marker of viable myocardium. This study was designed to address, in patients with left ...

This paper presents the first investigation into the MRI compatibility of a recently developed linear contractile actuator made of a silicone elastomer. The apparent absence of any degradation of both ...

Symmetry is a fundamental characteristic of most multi-cell animals. However, the cell division of embryonic cells is ...

A 3D engineered kidney glomerulus model replicates structural and mechanical features of the glomerular filtration barrier, ...

Abstract: In children with congenital heart disease, strain imaging might help in choosing the time-point for intervention. We evaluated three time delay estimation methods that use a-priori ...

A new, easily adopted, 3D-printed device will enable scientists to create models of human tissue with even greater control ...

We thank the University Life Science Facility in the Hong Kong Polytechnic University for providing confocal microscopy, IVIS system, flow cytometry, and centralized animal facility. We acknowledge ...

A group of Children's Hospital Los Angeles researchers found that ventilation managed by a computerized decision support (CDS ...

UW Medicine advances human tissue modelling with 3D printing. The device is small enough to fit on a fingertip.

植物以固着的生活方式生存，绝大多数的植物都是安安静静的，不会自己发生运动。不过，有些植物在特殊情况下确实可以产生明显可观察到的运动，比如含羞草叶片被触碰后的收拢和下垂、捕虫植物捕捉器的闭合运动等等。捕蝇草叶片的闭合运动（图片来源：参考文献[1]）动物 ...

引言当生命之初的奇迹悄然展开，一个小小的受精卵（zygote）如何在短短数日内，精确无误地复制自身，最终演变为一个完整的生命体？这其中最核心的环节，便是细胞的有丝分裂（mitosis）。每一步都要求完美，因为任何微小的偏差，都可能导致染色体数量异常， ...
