“Human mesenchymal stem cells (MSC) are non-controversial multipotent stem cells. Their presence in umbilical cord blood (UCB) has been debated in some studies and others report low counts per cord blood unit and poor proliferation rates. On the other hand, Wharton’s jelly of human umbilical cords appears to be a rich source of human MSC. This study derived 13 human Wharton’s jelly stem cell (WJSC) lines from 13 human umbilical cords (100%) and recovered 4.7 +/- 0.2 x 10(6) live WJSC/cm of cord before culture. Complex culture medium produced greater proliferation

rates of the WJSC in culture compared with simple medium. The mean population Silmitasertib supplier doubling times were 24.47 +/- 0.33 to 26.25 +/- 0.50 h in complex medium. The stem-cell markers of the WJSC were retained for at least 10 passages in both media. After programmed machine freezing, the thaw-survival rates of WJSC were 85-90% and they could be differentiated into neurons. Given the high derivation efficiency, availability of large numbers of fresh live cells, high expansion capabilities, prolonged maintenance of stem-cell properties and differentiation CX-5461 in vitro potential, it is proposed that human WJSC may be frozen at the same time as UCB in cord blood banks for regenerative medicine purposes.

“In many paediatric cardiac units chest radiographs are performed routinely before discharge after cardiac surgery. These radiographs Taselisib price contribute to radiation exposure. To evaluate the diagnostic impact of routine chest X-rays before discharge in children undergoing open heart surgery and to analyze certain risk factors predicting pathologic findings. This was a prospective (6 months) single-centre observational clinical study. One hundred twenty-eight consecutive children undergoing

heart surgery underwent biplane chest X-ray at a mean of 13 days after surgery. Pathologic findings on chest X-rays were defined as infiltrate, atelectasis, pleural effusion, pneumothorax, or signs of fluid overload. One hundred nine asymptomatic children were included in the final analysis. Risk factors, such as age, corrective versus palliative surgery, reoperation, sternotomy versus lateral thoracotomy, and relevant pulmonary events during postoperative paediatric intensive care unit (PICU) stay, were analysed. In only 5.5 % (6 of 109) of these asymptomatic patients were pathologic findings on routine chest X-ray before discharge found. In only three of these cases (50 %), subsequent noninvasive medical intervention (increasing diuretics) was needed. All six patients had relevant pulmonary events during their PICU stay.
