Predictors of prolonged mechanical ventilation after open heart surgery.

Journal of cardiovascular and thoracic research

Totonchi Z, Baazm F, Chitsazan M, Seifi S, Chitsazan M.
PMID: 25610551
J Cardiovasc Thorac Res. 2014;6(4):211-6. doi: 10.15171/jcvtr.2014.014. Epub 2014 Dec 30.

INTRODUCTION: Due to the importance of prolonged mechanical ventilation (PMV) as a postoperative complication, predicting "high-risk" patients by identifying predisposing risk factors is of important issue. The present study was aimed to identify perioperative variables associated with PMV in...

Iranian journal of reproductive medicine

Rajabpour-Niknam M, Totonchi M, Shahhosseini M, Farrokhi A, Alipour H, Eftekhari-Yazdi P.
PMID: 24639813
Iran J Reprod Med. 2013 Sep;11(9):733-40.

BACKGROUND: Embryo cryopreservation is the process that water is removed from the cell by cryoprotectant materials, and embryos are stored at temperature below zero. This process may affect the viability and developmental potential of embryos.OBJECTIVE: In this study, the...

Long term culture and differentiation of endothelial progenitor like cells from rat adipose derived stem cells.

Cytotechnology

Amerion M, Valojerdi MR, Abroun S, Totonchi M.
PMID: 29264678
