A study of optimization of the complex hyperbolic secant inversion pulses.

Magnetic resonance in medicine

Mao J, Virapongse C, Fitzsimmons JR.
PMID: 2314217
Magn Reson Med. 1990 Feb;13(2):293-8. doi: 10.1002/mrm.1910130211.

The conjugate gradient method is used to optimize the inversion slice profile produced by complex hyperbolic secant selective pulses. An improved quality is obtained for the inversion slice profile at a price, however, of a lower immunity to the...

PMID: 28947877
Contemp Oncol (Pozn). 2017;21(2):91-97. doi: 10.5114/wo.2017.68616. Epub 2017 Jun 30.

Mesenchymal stem cells (MSCs) are attractive seed cells for immunotherapy, tissue engineering and regenerative medicine due to their self-renewal and multidirectional differentiation abilities, diverse immunoregulatory functions and ease of isolation from a wide range of tissues. MSCs exert their...
