In this work, we combined three-dimensional (3D) scaffolds with flow perfusion bioreactors to evaluate the gradient effects of scaffold architecture and mechanical stimulation, respectively, on tumor ...

There is currently no way to stop calcification of the aortic valve. If all else fails, the valve must be replaced. To better ...

The endothelium lining the valve plays a critical role. It’s very important whether the valve consists of two or three leaflets.

The novel cue-induced analgesia paradigm allowed a compelling identification of a brainstem circuit element, i.e., somatostatin-expressing neurons within the ventrolateral periaqueductal grey that ...

This paper proposes a new asymmetrical duty cycle control method for a three-port bidirectional DC-DC converter with two current-fed ports interfacing with low voltage battery and ultracapacitor in a ...

Water makes up around 60% of the human body. More than half of this water sloshes around inside the cells that make up organs and tissues. Much of the remaining water flows in the nooks and ...

The FDA suspended clinical trials that send living cells and other biological materials overseas for genetic engineering in what the agency branded as “hostile countries.” According to the agency’s ...
