[Optical coherence tomography angiography in the diagnosis of retinal microvascular changes in chronic kidney disease (clinical observations)].

One distinctive pathological sign of chronic kidney disease (CKD) is microcirculatory disorders, which mark it as a microvascular disease. Similarity in the blood supply of the retina and kidneys, in the anatomy of their vascularization lead to identical complications in these organs. The retinal-choroidal microvascular system is easily accessible for clinical and morphological assessment and can be examined by the reproducible and non-invasive method - optical coherence tomography (OCT) and OCT angiography (OCTA).

[Specific characteristics of mismatch negativity in infants].

The mismatch negativity component of auditory event-related potentials was studied in fulI-term infants of the first month of life and adults. Acoustic stimuli with large deviance in passive oddball task were used. Research data revealed distinctive features in morphology and specificity in parameters of positive mismatch component in children at early ages.

[Morphological changes in ventricular germinal zone and neocortex of the cerebral hemispheres in human fetuses and newborns on weeks 22-40 of prenatal development].

In this study, we investigated the morphology of the ventricular germinal zone and neocortex of the cerebral hemispheres in the projection field no. 4 of the motor area in human fetuses in dynamics from week 22 to 40 of fetal development. Morphological study allowed us to clarify the following patterns of prenatal ontogeny of the human CNS.

[Structural changes in the germinal matrix of the brain of fetuses and neonatal infants with ventriculomegaly and congenital hydrocephalus].

Objective: To study structural changes in the germinal matrix (GM) in 22-to-40-week fetuses with ventriculomegaly (VM) and hydrocephalus (HC).

Material And Methods: The width of the ventricular groove was borne in mind while forming study groups (the brain in VM (n = 30), HC (n = 20)) and a comparison group (n = 30). To trace changes in GM transformation, each group was divided into 4 subgroups according to the gestational sign.
