Rescue of drowning victims and divers: is mechanical ventilation possible underwater?
The efficacy of underwater ventilation seems to be poor with any of the techniques trialed. Water aspiration frequently makes ventilation impossible and might foster emphysema aquosum-like air trapping and, therefore, increase the risk of pulmonary barotrauma during ascent. Because the limitations of underwater ventilation are substantial even under ideal conditions, it cannot be recommended presently for real diving conditions.
SP cells from MKN-45 possess cancer stem cell properties and proved that they were gastric cancer stem-like cells. SP cells from BGC-823 didn't possess cancer stem cell properties and proved that not all SP cells contain cancer stem-like cells in gastric cancer cell lines.
