Ontogenetic variations of proteins in neurons of the lateral preoptic nucleus of rats' hypothalamus under a modified light regime.

Proteins can be key biochemical markers for evaluating the functional activity of nervous system cells. They are involved in the proliferation and differentiation of nerve and glial cells and the arrangement of many metabolic functions of the brain. This study aimed to analyze the concentration of proteins in the neurons of the lateral preoptic nucleus (LPON) of the hypothalamus in mature and old rats under standard and altered lighting conditions.

FEATURES OF PRENATAL MORPHOGENESIS AND PECULARITIES OF THE UTRICULUS PROSTATICUS FETAL ANATOMY.

Objective: Aim: To determine the peculiarities of the structural organization of the utriculus prostaticus (UP) in pre-fetuses and fetuses.

Patients And Methods: Materials and methods: The study of macroscopic features and microscopic peculiarities of the prostate gland and the prostatic part of the urethra was carried out on 46 sections of human pre-fetuses and fetuses aged from 9 weeks to birth (31,0-375,0 mm PCL). The work uses the method of microscopic study of serial histological and topographic-anatomical specimens of the prostate gland, as well as the method of the thin preparation of the prostate part of the urethra in fetuses of different ages and morphometry.

VARIATIONS OF THE STRUCTURE, TOPOGRAPHY, BLOOD SUPPLY AND INNERVATION OF THE BRACHIORADIALIS IN HUMAN FETUS.

Objective: The aim of the research was to establish the features of age-related and individual anatomical variability of the brachioradialis, its blood supply, and innervation options.

Patients And Methods: Materials and methods: The study of the variant anatomy of the brachioradialis and its vascular and nervous structures was carried out on 25 preparations of human fetuses of 4-7 months, 81.0-270.

Morphohistochemical alterations of neurons of the supraoptic nucleus of the rat hypothalamus at different durations of the photoperiod and melatonin administration.

We studied the morphologic and histochemical organization of neurons of the hypothalamic supraoptic nucleus in rats exposed to different durations of photoperiod and injection of melatonin. Morphometric and histochemical analyses of neurons were performed after staining brain histological sections for RNA. Prolonged illumination leads to more pronounced changes in the parameters of hypothalamic structures at 2 a.

Periodic syndrome associated with the mutation of the receptor gene of the tumor necrosis factor (clinical case).

The paper deals with a case of TRAPS in a Ukrainian family. The manifestations of this syndrome appeared at the age of 2,5 years and gradually the attacks of fever became morefrequent and the recurrence was typical of this diagnosis. Classically, besides fever, there was an intense abdominal pain, such as an "acute abdomen", arthralgia in the right hip and headache.

Fetal anatomy of parathyroid glands.

Objective: The aim: To study the forms of anatomical variability of the external structure of the upper and lower parathyroid glands in the fetal period of human ontogenesis.

Patients And Methods: Materials and methods: The study involved 48 specimens of human fetuses with 81,0-375,0 mm of crown-rump length (CRL). The study was conducted by means of macromicroscopic preparation, morphometry and variation statistics method.

Peculiarities of prenatal vagina morphogenesis.

Objective: Introduction: The rapid development of perinatal gynecology requires from the anatomists comprehensive studies of the patterns of prenatal morphogenesis and the development of topographic and anatomical relationships of female reproductive organs in the human fetuses of different age groups. The aim: To study the development and formation of the vaginal topography in the prenatal period of human ontogenesis.

Patients And Methods: Materials and methods: The study has been conducted based on 23 series of histological and topographic-anatomical sections of human prefetuses aged 9-12 weeks with 31.

Incidence and risk factors of spina bifida in children.

Objective: Introduction: The pathogenesis of spina bifida depends on time, region, race and ethnicity. It is found in 4.7 per 10.
