Identification of the niche and phenotype of the first human hematopoietic stem cells [PDF]

, 2014
In various vertebrate species, the dorsal aorta (Ao) is the site of specification of adult hematopoietic stem cells (HSCs). It has been observed that the upregulation of essential hematopoietic transcription factors and the formation of specific intra ...

Additive Manufacturing of Patient‐Specific Intracranial Aneurysm Cell Culture Models

Advanced Materials Technologies, EarlyView.
Patient‐specific intracranial aneurysm models were fabricated using chocolate moulding, 3D printed water‐soluble cores, and direct resin 3D printing. Moulding PDMS around sacrificial cores made of chocolate or 3D printed water‐soluble resin yielded accurate, expandable, and endothelializable models that outperformed resin‐based approaches.

Coarctation of the Aorta [PDF]

Circulation, 1953
Coarctation of the aorta can be recognized in most instances by simple findings of physical examination. The anomaly is one which carries a variable prognosis. The condition may be tolerated through a long life with little incapacitation or may be accompanied by early and serious complications in the form of cardiac failure, aortic rupture, or ...
