Rowing produces marked changes in oxygen uptake, pulmonary ventilation, cardiac output and lactate with extreme levels for blood acid-base status and pronounced concentration of catecholamines in blood that could affect coagulation. With development of potassiaemia arrhythmia may even be developed that most often may be of supraventricular origin but sudden cardiac death is reported in rowers. ...

Alginate-based microcapsules are used for immunoisolation of cells to release therapeutics on a minute-to-minute basis.

This results in failure of the therapeutic cells. In the present study we show that commercial, crude alginates may contai...
