In the idiopathic intrauterine growth restriction where there are no clear maternal or fetal causes, the placenta may hold the key to its etiology. So, this study was undertaken to look for any placental and umbilical cord abnormality and to establish the relationship of fetal birth weight with placental measurements. In this study, 100 freshly delivered placentae were collected. The placenta a...

As a member of the chemokine family, CXCL3 was previously known to participate in many pathophysiological events. However, whether CXCL3 stimulates trophoblast invasion as a key process of preeclampsia pathogenesis remains largely unknown. Therefore, the aim of this study was to investigate this hypothesis and determine the effect of CXCL3 on the first trimester trophoblast. Seventy gravidas we...

BACKGROUND The aim of the study was to evaluate the relation between maternal placental Doppler velocimetry, levels of the maternal glucose, and clinical signs of vasculopathy in pregnancy complicated by pregestational diabetes mellitus. METHODS AND RESULTS A retrospective study of 155 pregestational diabetic women between the 22nd and 40th weeks of pregnancy, categorized in White classificat...

PURPOSE In placentas from uncomplicated pregnancies, Hofbauer cells either disappear or become scanty after the fourth to fifth month of gestation. Immunohistochemistry though, reveals that a high percentage of stromal cells belong to Hofbauer cells. The aim of this study was to investigate the changes in morphology and density of Hofbauer cells in placentas from normal and pathological pregnan...

This review will consider whether nitric oxide (NO) contributes to maternal systemic vasodilation during pregnancy, regulates uterine and fetoplacental blood flow, and is involved in uterine quiescence prior to parturition. Also, whether a deficiency of NO contributes to the hypertensive disorder of pregnancy, preeclampsia, will be considered. The biosynthesis of NO increases in gravid rats and...

OBJECTIVE To report secondary or additional findings arising from introduction of non-invasive prenatal testing (NIPT) for aneuploidy by whole genome sequencing as a clinical service. METHODS Five cases with secondary findings were reviewed. RESULTS In Case 1, NIPT revealed a large duplication in chromosome 18p, which was supported by arrayCGH of amniocyte DNA, with final karyotype showing ...

Several histopathological features are found more frequently in placentas from pregnancies complicated by fetal growth restriction (FGR), including villous infarction, maternal vascular changes and villous morphological alterations, although around one quarter of placentas associated with FGR lack any morphological abnormality on routine examination. Since similar changes may also affect clinic...

PURPOSE There is a paucity of information on the serum soluble vascular endothelial growth factor receptor-2 (sVEGFR-2) concentrations, membranous VEGFR-2 expression and the mechanism involved in their modulations during the clinical onset of pre-eclampsia. This cross-sectional study was conducted to evaluate the concentration of sVEGFR-2 in serum and to investigate the expression of membranous...

background: different investigation showed that 5-methoxypsoralen and 8- methoxypsoralen reduce birth rates in the rats. objective: in this study we worked out the effect of methoxsalen together with ultraviolent a (uva) radiation on mature balb/c mice spermatogenesis. materials and methods: the ld50 standard was determined 160 mg/kg and the uva dose which causes erythema was calculated 0.046 j...
