Experimental Reconstruction of the Optic Nerve with a Sural Nerve Graft: An in Vivo Experimental Study.

Background: Neurosurgical interventions and trauma are common causes of damage to the optic nerve. This determines the relevance of research for solutions aimed at restoration of the nerve's anatomical integrity, electrical conductivity, and subsequently - restoration of its function. Restore a damaged (cut) optic nerve using n.

[Intracellular pH measurement in glioblastoma cells: the possibilities of phosphorus-31 MR spectroscopy].

Objective: To analyze intracellular pH measurement with phosphorus-31 MR spectroscopy in glioblastoma cells and to compare these data with intracellular pH in healthy volunteers.

Material And Methods: There were 10 patients aged 41 - 67 years with supratentorial glioblastomas. Intracellular pH in glioblastoma cells was compared with pH in healthy persons.

[Evaluation of autogenous mandibular bone block resorption in horizontal alveolar ridge augmentation].

Aim: To perform a prospective evaluation of splitted bone block resorption after augmentation procedure using cone beam computed tomography, and evaluation of clinical results.

Material And Methods: Bone blocks were harvested from the external oblique line of the mandible in 100 patients aged from 23 to 68 years, (64 females and 36 males). All of them underwent ridge augmentation using splitted bone blocks (SBB) technique.

[The evaluation of the applicability of thermoplastic polymers as a denture base material].

Aim: To assess and compare physical and mechanical properties of various thermoplastic materials and their feasibility for the denture bases.

Material And Methods: Dakril-81 (Russia), Evichard (Avidsan Russia), polymethyl methacrylate (Saudi Arabia) were used for the comparative assessment of applicability of various brands of thermoplastic materials based on polymethyl methacrylate (PMMA). The standard techniques were used for a detailed study of their physical and mechanical properties: flexural stress, modulus of elasticity, deformation under compression and tension, flowability.

[Individual preoperative 3D modeling of vascular brain pathology].

The possibility of segmenting three-dimensional objects by DICOM-series is well known and available both on specialized workstations and on personal computers. The technique, however, is relatively rarely used in clinical practice, and we believe that the benefits of preoperative preparation using segmented 3D models are underestimated. The article is devoted to our experience in using segmentation of anatomical structures based on CT and MRI for preoperative preparation for surgical operations performed in neurosurgical departments on patients with vascular pathology.
