[The phenomenon of long-term survival in glioblastoma patients. Part I: the role of clinical and demographic factors and an IDH1 mutation (R 132 H)].

Unlabelled: The median overall survival of glioblastoma patients is about 15 months. Only a small number of patients survive 3 years. The factors of a favorable prognosis for the 'longevity phenomenon' in glioblastoma patients are not fully understood.

Long association tracts of the human white matter: an analysis of 18 hemisphere dissections and in vivo HARDI-CSD tractography.

Background: Anatomy of the conduction tracts of the cerebral cortex has been studied for a long time. Invention of diffusion tensor tractography renewed interest in this subject. The objectives of this work were to develop and improve protocols for dissection of the long association tracts of the human brain with studying the features of their segmentation, topography, and variability, compare the obtained data with the MR tractography data, and prepare for further clinical and anatomical studies.

Clinical guidelines for the use of intraoperative fluorescence diagnosis in brain tumor surgery.

In this paper, we present a review of current literature on the application of intraoperative fluorescence diagnosis and fluorescence spectroscopy using 5-aminolevulinic acid in surgery for various types of brain tumors, both alone and in combination with other neuroimaging methods. Authors' extensive experience with these methods allowed them to develop a set of clinical guidelines for the use of intraoperative fluorescence diagnosis and fluorescence spectroscopy in surgery of brain tumors.

Effects of metenkephalin on the formation and fixation of defensive temporal associations and on the incorporation of C14-leucine in brain proteins of the rat.

When 25 microgram of metenkephalin is injected subcutaneously into rats, the development of temporal associations is somewhat impaired, but the fixation of them is enhanced. The latter effect is observed more clearly when metenkephalin is injected not before, but immediately after the development of conditioned reflexes. Under the influence of metenkephalin, there is an increase in the incorporation of C14-leucine into the insoluble proteins of the hippocampus and basal ganglia.
