Phys Rev Lett. 2013 Mar 08;110(10):107204. doi: 10.1103/PhysRevLett.110.107204. Epub 2013 Mar 07.

We investigate the two-dimensional highly spin-polarized electron accumulation layers commonly appearing near the surface of n-type polar semiconductors BiTeX (X=I, Br, and Cl) by angular-resolved photoemission spectroscopy. Because of the polarity and the strong spin-orbit interaction built in the...

The exclusive reaction γp→K(+)π(-)Σ(+) was measured for the first time using linearly polarized photons at beam energies from 1.85 to 2.96 GeV. Angular distributions in the rest frame of the K(+)π(-) system were fitted to extract spin-density matrix elements...

Enhanced efficacy of human brain-derived neural stem cells by transplantation of cell aggregates in a rat model of Parkinson's disease.

Journal of Korean Neurosurgical Society

Shin ES, Hwang O, Hwang YS, Suh JK, Chun YI, Jeon SR.
PMID: 25535514
J Korean Neurosurg Soc. 2014 Nov;56(5):383-9. doi: 10.3340/jkns.2014.56.5.383. Epub 2014 Nov 30.

OBJECTIVE: Neural tissue transplantation has been a promising strategy for the treatment of Parkinson's disease (PD). However, transplantation has the disadvantages of low-cell survival and/or development of dyskinesia. Transplantation of cell aggregates has the potential to overcome these problems,...
