    Aim. Neural progenitor cells (NPC) are used for the development of cell therapies of neurological diseases. Their stereotaxic transplantation in the middle cerebral artery occlusion (MCAO) model imitating ischemic stroke results in symptom aleviation. However, exploration of less invasive transplantation options is essential, because stereotaxic transplantation is a complex procedure and can be applied to humans only by vital indications in a specialized neurological ward. The aim of the present study was to evaluate the efficacy of cell therapy of the experimental ischemic stroke by the intra-arterial transplantation of NPC.Materials and methods. NPC for transplantation (IPSC-NPC) were derived by two-stage differentiation of cells of a stable line of human induced pluripotent stem cells. Stroke modeling in rats was carried out by transitory 90 min endovascular MCAO by a silicon-tipped filament. NPC were transplanted 24 hours after MCAO. Repetitive magnetic resonance tomography of experimental animals was made with the Bruker BioSpin ClinScan tomograph with 7 Tl magnetic field induction. Animal survival rate and neurological deficit (using mNSS standard stroke severity scale) were evaluated at the 1st (before IPSC-NPC transplantation), 7th and 14th day after transplantation. Histological studies were carried out following standard protocols.Results. Intra-arterial transplantation of 7 Γ— 105 IPSC-NPC in 1 ml at a constant 100 l/min rate in case of secured blood flow through the internal carotid artery did not cause brain capillary embolism, additional cytotoxic brain tissue edemas or other complications, while inducing increase of animal survival rate and enhanced revert of the neurological deficit. IPSC-NPC accumulation in brain after intra-arterial infusion was demonstrated. Some cells interacted with the capillary endothelium and probably penetrated through the blood-brain barrier.Conclusion. Therapeutic efficacy of the systemic, intra-arterial administration of NPC in ischemic stroke has been experimentally proven. A method of secure intra-arterial infusion of cell material into the internal carotid artery middle in rats has been developed and tested.ЦСль.

    A Guide to Mathematical Tables is a supplement to the Guide to Mathematical Tables published by the U.S.S.R. Academy of Sciences in 1956. The tables contain information on subjects such as powers, rational and algebraic functions, and trigonometric functions, as well as logarithms and polynomials and Legendre functions. An index listing all functions included in both the Guide and the Supplement is included.Comprised of 15 chapters, this supplement first describes mathematical tables in the following order: the accuracy of the table (that is, the number of decimal places or significan
