INTERRELATION OF CHANGES IN CONCENTRATION OF LEPTIN AND ω-3 FAMILY ACIDS IN THE PLACENTA AT THE REACTIVATION OF CYTOMEGALOVIRUS INFECTION IN THE III TRIMESTER OF HUMAN PREGNANCY
A gas-chromatographic study was conducted of the content of essential polyunsaturated fatty acids of the ω-3 family: eicosapentaenoic and docosahexaenoic, an enzyme-linked immunosorbent assay of leptinin the homogenate of placental tissue in women who during the third trimester of gestation (32 weeks) underwent reactivation of chronic cytomegalovirus infection with an antibody titer Immunoglobulin class G to cytomegalovirus 1:1600. The main group of studies was 42 placentas taken from women with cytomegalovirus infection during the period of labor. The obtained data were compared with similar parameters of the control group, which included 35 placental tissues of practically healthy women in childbirth. Based on the analysis of the data obtained, it was found that the reactivation of chronic cytomegalovirus infection in the third trimester of pregnancy (32 weeks) is associated with decrease in the concentration of ω-3 essential polyunsaturated fatty acids: eicosapentaenoic by 23 % (р < 0.01) and docosahexaenoic by 42 % (р < 0.001) with a simultaneous increase in the concentration of leptin in the placental tissue by 61 % (р < 0.001). In these conditions, the mechanisms of regulation of the transmission of fatty acids from the peripheral blood of the mother to the blood of the developing fetus through the placenta are disrupted. The contents of leptin during pregnancy is an important indicator that carries information not only about the energy reserves of the maternal organism, but also about the state of the fe^lacental complex
Реализация апоптоза в ядрах синцитиотрофобласта ворсинок плаценты у беременных, перенесших обострение герпес-вирусной инфекции в зависимости от содержания в гомогенате плаценты аннексина V
The reason of increase apoptosis in sincythiotrophoblast is suppression of activity ATP-ase, moving phosphatydilserin on an external membrane sincythiotrophoblast, and increase of quantity annexin V in homogenate placentae.Причиной увеличения апоптоза в синцитиотрофобласте является подавление активности аденозинтрифосфатазы, перемещение фосфатидилсерина на внешнюю мембрану синцитиотрофобласта, повышение количества аннексина V в гомогенате плаценты
Ideal MHD theory of low-frequency Alfven waves in the H-1 Heliac
A part analytical, part numerical ideal MHD analysis of low-frequency Alfven
wave physics in the H-1 stellarator is given. The three-dimensional,
compressible ideal spectrum for H-1 is presented and it is found that despite
the low beta (approx. 10^-4) of H-1 plasmas, significant Alfven-acoustic
interactions occur at low frequencies. Several quasi-discrete modes are found
with the three-dimensional linearised ideal MHD eigenmode solver CAS3D,
including beta-induced Alfven eigenmode (BAE)- type modes in beta-induced gaps.
The strongly shaped, low-aspect ratio magnetic geometry of H-1 causes CAS3D
convergence difficulties requiring the inclusion of many Fourier harmonics for
the parallel component of the fluid displacement eigenvector even for shear
wave motions. The highest beta-induced gap reproduces large parts of the
observed configurational frequency dependencies in the presence of hollow
temperature profiles

DISTURBANCE OF THE PROGESTERONE AND ITS METABOLITES SYNTHESIS IN THE DEVELOPMENT OF NEUROLOGICAL DISORDERS IN CHILDREN AFTER CYTOMEGALOVIRUS INFECTION DURING PREGNANCY
Cytomegalovirus (CMV) infection is one of the causes of congenital neurological disorders and the virus itself is the most common viral agent causing an imbalance in the production of placenta progesterone and its neuroactive metabolites – allopregnenolone and 5α-dihydroprogesterone. The aim was to evaluate the concentration of progesterone and its metabolites – 5α-dihydroprogesterone and allopregnenolone – in placenta during exacerbation of CMV infection in the first trimester of pregnancy, and the impact of these disturbances on the development of neurological disorders in children. We examined 30 pregnant women with exacerbation of CMV infection in the first trimester of pregnancy and 30 pregnant women with latent disease; and later their newborns. The enzyme immunoassay was used to determine concentration of progesterone in placenta; the histochemical method – to determine 5α-dihydroprogesterone and allopregnenolone. Newborns underwent neurosonography studies. Exacerbation of CMV infection in the first trimester of pregnancy decreased progesterone in placenta by 1.3 times, 5α-dihydroprogesterone – by 1.73 times and allopregnenolone – by 2 times. Ultrasound examination of the brain showed ventriculomegaly, periventricular ischemia, and pseudocysts in newborns up to one year from mothers with exacerbation of CMV during pregnancy. Later, minimal brain dysfunctions were manifested by motor disorders, increased general, vegetative excitability, and a tendency to digestive and sleep disorders. The data obtained indicate that the exacerbation of CMV infection in the first trimester of pregnancy is interrelated with a decrease in the concentration of progesterone and its metabolites (5α-dihydroprogesterone, allopregnenolone) in the placenta and development of neurological dysfunction in newborns
