In contrast, GSCs resulted in only I functional phenotype: cells with high electrical resistance and active membrane properties capable of generating action potentials.

CONCLUSION: AHNSCs and stem cells from AC II and GBM differ with respect to proliferation, tumor-forming capacity, and rate and pattern of differentiation.”
“THIS ARTICLE PRESENTS an check details assessment of the power of ideas and their

role in initiating change and progress. The enormous potential cascade effect is illustrated by examining the movement of Modernism in the arts. Next, the immense scope and capabilities of the modern scientific endeavor-with robotic space exploration at the scale of 10(9) meters at one extreme and the wonders of nanoscience at the scale

of 10(-9) m at the other-are examined. The attitudes and philosophies of neurological Surgery are related to those involved in the Modernist movement and placed on the defined scale selleck of contemporary scientific activity.”
“OBJECTIVE: We retrospectively reviewed the results of stereotactic SPTLC1 endocavitary irradiation with colloidal Re-186 in the treatment of cystic craniopharyngiomas.

METHODS: Among 54 consecutive patients included in a Re-186 stereotactic endocavitary irradiation procedure, 42 patients (29 male and 13 female; average age, 38.7 years) received therapeutic injection via intracystic catheter introduced under stereotactic conditions. The mean follow-up period was 43 months

(range, 8-148 months). Endocavitary irradiation was the primary treatment for 15 patients and an adjuvant treatment for 27 patients. The mean volume before irradiation was 8.07 mm(3), and the mean radiation dose was 381 MBq.

RESULTS: Cystic mean volume after irradiation was 2.6 cm(3) (P < 0.001 with initial volume). The retraction of the cyst was complete for 17 patients (44%) and partial for 17 (44%). In partial retraction, cystic volume decreased more than 50% for 12 (3%) patients and less than 25% (13%) for 5. Cystic volume remained the same or increased for 5 (13%) patients.
