Article Abstract
This work is dedicated to the study of anatomo-physiological peculiarities of the construction and cerebrovascular circulation of the vestibulo-ocular formations of the brain stem of the human cerebrum. The analysis of anatomo-physiological data enable to convince that the arches of the vertical and horizontal vestibulo-ocular reflexes include many structures of the brain stem of the human cerebrum, which are located along its longitude from the superior colliculi to caudal sections of brain stem. There is an existence of separate mechanisms of horizontal and vertical vestibulo-ocular interaction. The peculiarity of cerebrovascular circulation of main vestibulo-ocular structures is their profuse vascularisation chiefly by branches of the vertebro basilar system of arteries, which widely connected between each other, providing sufficiently profuse circulation in normal conditions of vital activity. The anatomical information above has great importance for the correct interpretation of the symptoms of infarctions in vertebro-basilar pool of the cerebrum, diagnostics and expert appreciation of these pathological states.

Background/objectives: Glioblastoma multiforme (GBM) is the most common high-grade primary brain cancer in adults. Despite efforts to advance treatment, GBM remains treatment resistant and inevitably progresses after first-line therapy. Induced neural stem cell (iNSC) therapy is a promising, personalized cell therapy approach that has been explored to circumvent challenges associated with the current GBM treatment.

Fetal bovine serum (FBS) has long been the standard supplement in cell culture media, providing essential growth factors and proteins that support cell growth and differentiation. However, ethical concerns and rising costs associated with FBS have driven researchers to explore alternatives, particularly human platelet lysate (HPL). Among these alternatives, fibrinogen-depleted HPL (FD-HPL) has gained attention due to its reduced thrombogenicity, which minimizes the risk of clot formation in cell cultures and enhances the safety of therapeutic applications.

Semaphorin 3A (Sema3A) is an axon guidance molecule, which is also abundant in the adult central nervous system (CNS), particularly in perineuronal nets (PNNs). PNNs are extracellular matrix structures that restrict plasticity. The cellular sources of Sema3A in PNNs are unknown.

Gravitational changes have been shown to cause significant abnormalities in various body systems, including the cardiovascular, immune, vestibular, and musculoskeletal systems. While numerous studies have examined the response of the vestibular system to gravitational stimulation, research on functional changes in the peripheral inner ear remains limited. The inner ear comprises two closely related structures: the vestibule and cochlea.

Among the various causes of rhomboencephalitis, infection is the most common. However, conventional microbiological methods often yield negative results, making diagnosis challenging and leading to extensive, often inconclusive, diagnostics. Advanced molecular techniques like metagenomic next-generation sequencing (mNGS) offer a powerful and efficient approach to pathogen identification.
