'Immortalized' cells enable researchers to grow human arteries

Duke University researchers have successfully grown human arteries in a laboratory using 'immortalized' cells, overcoming the hurdle of human artery cells not being able to divide long enough. The team used the hTERT gene to extend the life span of smooth muscle cells, allowing them to form functional arteries.

Researchers use numerical models to examine blood flow in artificial heart valves

The Georgia Tech research aims to develop advanced Computational Fluid Dynamics (CFD) techniques to study blood flow turbulence in heart valves. The team will create a virtual environment that accurately models the turbulent flow environment, which could lead to better design and reduced thromboembolic complications.

New tool tackles nursing shortage

A new instrument, Decisional Involvement Scale (DIS), assesses the level of involvement registered nurses have in decisions affecting their work environment and patient care. The DIS can help hospitals identify areas for improvement and implement changes to reduce staff turnover and enhance quality of care.
