Open versus endovascular REBOA control of blood loss during cesarean delivery in the placenta accreta spectrum: A single-center retrospective case control study.

Objective: The aim of this study was to compare two vascular control options for blood loss prevention and hysterectomy during cesarean delivery (CD): endovascular balloon occlusion of the aorta (REBOA) and open bilateral common iliac artery occlusion (CIAO) in women with extensive placenta accreta spectrum (PAS).

Study Design: This was retrospective comparison of cases of PAS using either CIAO (October 2017 through October 2018) or REBOA (November 2018 through November 2019) to prevent pathologic hemorrhage during scheduled CD. Women with confirmed placenta increta/percreta underwent either CD then intraoperative post-delivery, pre-hysterectomy open vascular control of both CIA (CIAO group) or pre-operative, ultrasound-guided, fluoroscopy-free REBOA followed by standard CD and balloon inflation after fetal delivery (REBOA group).

X-linked and autosomal dominant forms of the ichthyosis in coinheritance.

According to modern classification, there are two forms of inherited ichthyoses: syndromic and non-syndromic, each of them consists of more than ten different nosologies. The commonest types of the ichthyosis are X-linked recessive (prevalence 1/2000-6000 in men) and autosomal dominant, or ichthyosis vulgaris with incomplete penetrance (1/250-1000). The X-linked form is associated with mutations in steroid sulfatase STS gene, it is noteworthy that there is a full deletion of the gene in 90% of cases.

Combined value of placental alpha microglobulin-1 detection and cervical length via transvaginal ultrasound in the diagnosis of preterm labor in symptomatic patients.

Aim: We aimed to evaluate the combined value of placental alpha microglobulin-1 (PAMG-1) and cervical length (CL) via transvaginal ultrasound for assessing risk of imminent spontaneous preterm delivery in patients presenting with threatened preterm labor (PTL).

Methods: Clinical exam, PAMG-1 test, cardiotocography, and CL measurement via transvaginal ultrasound were performed on all patients meeting inclusion criteria. Ninety-nine patients at 22 -36 gestational weeks with the symptoms of PTL were included.

Comprehensive global genome dynamics of show ancient diversification followed by contemporary mixing and recent lineage expansion.

is the world's most prevalent bacterial sexually transmitted infection and leading infectious cause of blindness, yet it is one of the least understood human pathogens, in part due to the difficulties of in vitro culturing and the lack of available tools for genetic manipulation. Genome sequencing has reinvigorated this field, shedding light on the contemporary history of this pathogen. Here, we analyze 563 full genomes, 455 of which are novel, to show that the history of the species comprises two phases, and conclude that the currently circulating lineages are the result of evolution in different genomic ecotypes.

Effect of Cytokines on the Formation Tube-Like Structures by Endothelial Cells in the Presence of Trophoblast Cells.

Despite ample data on cytokine secretion in the uteroplacental interface, the influence of microenvironment cells, in particular, trophoblast cells on angiogenesis and the role of cytokines in this process remain poorly studied. We studied the influence of cytokines on the formation of tube-like structures by endothelial cells in the presence of trophoblast cells and showed that trophoblast cells suppressed the angiogenic potential of endothelial cells. Antiangiogenic cytokines IFN-γ, IL-10, TNF-α, and TGFβ via modulation of trophoblast cells stimulated the formation of tube-like structures by endothelial cells.

Clinical strains of Streptococcus agalactiae carry two different variants of pathogenicity island XII.

Streptococcus agalactiae or Group B streptococci (GBS) are a common cause of serious diseases of newborns and adults. GBS pathogenicity largely depends on genes located on the accessory genome including several pathogenicity islands (PAI). The present paper is focused on the structure and molecular epidemiological analysis of one of the GBS pathogenicity islands-the pathogenicity island PAI XII (Glaser et al.

Effect of THP-1 Cells on the Formation of Vascular Tubes by Endothelial EA.hy926 Cells in the Presence of Placenta Secretory Products.

We studied the effect of THP-1 cells on the formation of vessel-like structures by endothelial cells in the presence of placenta-conditioned media. Addition of THP-1 cells to endothelial cells cultured in the presence of media conditioned by first-trimester placentas led to an increase in the length of cell tubes and reduced their number in comparison with endothelial cell monoculture. In the presence of media conditioned by third-trimester placentas, THP-1 cells did not affect the length and number of cell tubes formed by endothelial cells.

Detection of human genome mutations associated with pregnancy complications using 3-D microarray based on macroporous polymer monoliths.

Analysis of variations in DNA structure using a low-density microarray technology for routine diagnostic in evidence-based medicine is still relevant. In this work the applicability of 3-D macroporous monolithic methacrylate-based platforms for detection of different pathogenic genomic substitutions was studied. The detection of nucleotide replacements in F5 (Leiden G/A, rs6025), MTHFR (C/T, rs1801133) and ITGB3 (T/C, rs5918), involved in coagulation, and COMT (C/G, rs4818), TPH2 (T/A, rs11178997), PON1 (T/A rs854560), AGTR2 (C/A, rs11091046) and SERPINE1 (5G/4G, rs1799889), associated with pregnancy complications, was performed.

Detection of Antibodies In Vitro Binding to Endothelial Cells in the Sera from Women with Normal Pregnancy and Preeclampsia.

Activity of serum antibodies in vitro binding to endothelial cells in women with normal pregnancy and preeclampsia was studied. Flow cytometry detected peculiarities of antibody binding to endothelial cells in health and disease. Detection of antiendothelial antibodies in trimesters II and III can be diagnostically important in preeclampsia.

Proliferative and Migration Activity of JEG-3 Trophoblast Cell Line in the Presence of Cytokines.

TNFα inhibited proliferation and did not inhibit migration JEG-3 trophoblast cells, IL-1β stimulated both cell proliferation and migration, IL-6 and IL-8 stimulated only cell migration, IFNγ has either stimulating or inhibitory effect on proliferation of trophoblast cells depending on its concentration. Cytokines IL-10 and IL-4 stimulated only migration of trophoblast cells. VEGF, PlGF, and TGFβ stimulated both proliferation and migration, and bFGF only migration of trophoblast cells.

Effect of Monocyte-Like THP-1 Cells on the Formation of Vascular Tubes by EA.Hy926s Endothelial Cells in the Presence of Cytokines.

The interaction of endothelial cells with cells of the microenvironment, including monocytes/ macrophages, and extracellular matrix during angiogenesis is controlled by cytokines. The stimulating effect bFGF, IL-8, and VEGF on the formation of capillary-like structures by endothelial cells was demonstrated in both monoculture and in co-culture with THP-1 cells; in the latter case, the effects of bFGF and VEGF were more pronounced. IL-8 reduced branching of vascular tubes in co-culture in comparison with monoculture of endothelial cells.

Methylation levels of SLC23A2 and NCOR2 genes correlate with spinal muscular atrophy severity.

Spinal muscular atrophy (SMA) is a monogenic neurodegenerative disorder subdivided into four different types. Whole genome methylation analysis revealed 40 CpG sites associated with genes that are significantly differentially methylated between SMA patients and healthy individuals of the same age. To investigate the contribution of methylation changes to SMA severity, we compared the methylation level of found CpG sites, designed as "targets", as well as the nearest CpG sites in regulatory regions of ARHGAP22, CDK2AP1, CHML, NCOR2, SLC23A2 and RPL9 in three groups of SMA patients.

[Signal molecules of endometrium: gerontological and general pathhological aspects].

The review describes neuro-immuno-endocrine signal molecules expression in human endometrial cells in the normal conditions, in the pathology and during aging. Human endometrial cells synthesizes estrogen, progesterone, estradiol, progestin, cell adhesion molecules (integrines α1β1, α4β1, αVβ3, L-selectin, Е-catgerin, MUC1), grow factors (TGF, EGF, HB-EGF, IGF), cytokines (IL-1, IL-2, INF-α, IL-12, СХСL10, CXCL11, CXCR3), various immune cells markers (CD68, CD105, CD163, CD16, CD56, CD4, CD8), heat shock proteins (HSP60, HSP70, HSP90, VEGF, MMP). Changes of this molecules expression level are the base of the social significant diseases as endometriosis, endometrial cancer and infertility.

Influence of peripheral blood microparticles of pregnant women with preeclampsia on the phenotype of monocytes.

Platelet- and endothelial-derived microparticles influence the phenotype of peripheral blood leukocytes and induce production of proinflammatory cytokines. The influence of blood plasma microparticles of pregnant women on the surface receptor expression on intact or activated monocytes is still unexplored. This study was carried out to test the hypothesis that peripheral blood microparticles of women with normal pregnancy and women with preeclampsia have different influence on the expression of surface molecules on monocytes.

Systems genetics view of endometriosis: a common complex disorder.

Endometriosis is a condition in which cells derived from the endometrium grow outside the uterus, e.g. in the peritoneum (external genital endometriosis).

Development of a receptor-targeted gene delivery system using CXCR4 ligand-conjugated cross-linking peptides.

Background: Success in gene therapy greatly depends on the efficiency of nucleic acid delivery. Important features of the carriers for gene delivery should include an enhanced transfection ability, targeting of specific receptors and low toxicity. In the present study, we characterized CXCR4-targeted cross-linking peptides modified with an N-terminal fragment of chemokine stromal cell-derived factor-1α as carriers for gene delivery.

Detection of microparticles of leukocytic origin in the peripheral blood in normal pregnancy and preeclampsia.

Microparticles are microvesicles forming during cell activation and as a result of apoptotic cell death. Normal pregnancy is associated with apoptosis induction in active immune system cells, present in the decidual tissue. Preeclampsia is associated with activation of the peripheral blood leukocytes and more intense apoptosis of the trophoblast cells.

Effect of factors produced by the placenta on cytokine secretion by THP-1 cells cultured on a 3D scaffold.

We compared the effects of soluble products from the placenta obtained from women with normal pregnancy and pregnancy complicated by preeclampsia on cytokine secretion by THP-1 cells cultured on a 3D Matrigel scaffold. In the presence of soluble products from all placentas, the cells actively secreted IL-8, MCP-1, and soluble forms of CD14, TNFRI, and TNFRII receptors. Secretion of VEGF was below the spontaneous level.

Effect of placenta secretory products on migration activity of endothelial EA.Hy926 cells.

We studied the influence of factors secreted by the placenta in physiological and preeclampsia-complicated pregnancy on migration activity of endothelial EA.Hy926 cells. It was found that migration of endothelial cells was more intensive in the presence of secretory factors from trimester I placentas in comparison with trimester III placentas and was lower in the presence of placental factors in preeclampsia in comparison with physiological pregnancy.

Composition of the vaginal microbiota in women of reproductive age--sensitive and specific molecular diagnosis of bacterial vaginosis is possible?

Background And Objective: Bacterial vaginosis (BV) is the most common vaginal disorder, characterized by depletion of the normal lactobacillus-dominant microbiota and overgrowth of commensal anaerobic bacteria. This study aimed to investigate the composition of the vaginal microbiota in women of reproductive age (healthy women and women with BV), with the view of developing molecular criteria for BV diagnosis.

Materials And Methods: Vaginal samples from 163 women (79 control, 73 BV and 11 intermediate (Lactobacillary grade II flora) cases) were analyzed using 454 pyrosequencing of the hypervariable regions V3-V4 of the 16S rRNA gene and 16 quantitative bacterial species/genus-specific real-time PCR assays.

[Protective effect of melatonin and epithalon on hypothalamic regulation of reproduction in female rats in its premature aging model and on estrous cycles in senescent animals in various lighting regimes].

Potential neuroprotective effects of the pineal gland hormone melatonin and peptide preparation epitalon on estrous cycles and the central regulation of reproduction in female rats exposed to unfavourable environmental factors have been studied. Estrous cycles of young, mature and aging rats exposed to light pollution were described. The diurnal dynamics and daily mean content of biogenic amines in the hypothalamic areas responsible for gonadotropin-releasing hormone synthesis and secretion in animals of different age groups were investigated.
