Increase of TOC in all pregnant women our study points to latent oxidative stress in pregnancy. Fe might have a role in etiopathogenesis of preeclampsia while the increase of TAC in the very beginning of preeclampsia might represent a stressdefence mechanism of the body. It has still to be revealed whether significantly higher serum Fe levels are associated with preeclampsia as a cause or as a consequence of this disorder.

Purpose Isolated cor triatriatum sinistrum (CTS) is a heart malformation in which a perforated fibromuscular membrane divides the left atrium into two chambers. When communication between these chambers is restricted, a patient may have signs and symptoms of mitral stenosis. The later stages of pregnancy are associated with tachycardia and increases in intravascular volume. We describe how this altered physiology may affect pregnant women with asymptomatic CTS. We also review the literature relating to pregnancy in patients with CTS.Clinical features A 30-yr-old primigravida, at 40 weeks of gestation with pre-pregnancy diagnosed asymptomatic CTS, was admitted for delivery. She had no cardiac symptoms during pregnancy, and her vaginal delivery under epidural analgesia was uneventful. This cardiac malformation is infrequently described in pregnant women, but a literature review showed that the physiology of late pregnancy with increases in hemodynamic variables may result in cardiac decompensation. Conclusion While our patient with isolated CTS and an unrestrictive intra-atrial membrane had an asymptomatic pregnancy and an uneventful labour, the literature review suggests that the increase in intravascular volume and heart rate that occurs during late pregnancy and after delivery may result in cardiac decompensation, even in patients with asymptomatic CTS. RésuméObjectif Le coeur triatrial gauche (CTG) isole´est une malformation cardiaque dans laquelle une membrane fibromusculaire perfore´e divise l'oreillette gauche en deux chambres. Lorsque la communication entre ces chambres est restreinte, le patient pourrait pre´senter les signes et symptômes d'une ste´nose mitrale. En fin de grossesse, on peut observer de la tachycardie et des augmentations du volume intravasculaire. Nous de´crivons la façon dont cette physiologie modifie´e pourrait affecter les femmes enceintes atteintes de CTG asymptomatique. Nous passons e´galement en revue la litte´rature portant sur la grossesse chez les patientes atteintes de CTG. É léments cliniques Une primigeste de 30 ans, a`40 semaines de grossesse et chez laquelle un diagnostic de CTG asymptomatique avait e´te´pose´avant la grossesse, a e´te´admise a`l'hôpital pour l'accouchement. Pendant la grossesse, elle n'a pre´sente´aucun symptôme cardiaque, et Drs Bojanić and Bursać contributed equally to this work.

Karst aquifers are important sources of thermal and groundwater in many parts of the world, such as the Alpine–Dinaric–Carpathian region in Europe. The Upper Triassic dolomites are regionally recognized thermal and groundwater aquifers but also hydrocarbon reservoirs. They are characterized by predominantly fractured porosity, but the actual share of depositional and diagenetic porosity is rarely investigated. In this research, we presented the geometric characterization of the measured microporosity of the Upper Triassic dolomites of the Žumberak Mts (Croatia), through thin-section image processing and particle analysis techniques. Pore parameters were analyzed on microphotographs of impregnated thin sections in scale. A total of 2267 pores were isolated and analyzed. The following parameters were analyzed: pore area, pore perimeter, circularity, aspect ratio (AR), roundness, solidity, Feret AR, compactness, and fractal dimension. Furthermore, porosity was calculated based on the pore portion in each image. The effective porosity on rock samples was determined using saturation and buoyancy techniques as an accompanying research method. We analyzed distributions of each parameter, their correlation, and most of the parameters are characterized by an asymmetric or asymmetric normal distribution. Parameters that quantify pore irregularities have similar distributions, and their values indicate the high complexity of the pore geometry, which can significantly impact permeability.

The placental and fetal lung tissue of preeclamptic patients tended to have higher coefficients of variation throughout pregnancy. These results were significantly higher when associated with low-birth-weight babies. There were no significant differences in fetal liver tissue between normotensive and preeclamptic groups.

Ž. Žegarac).emergency cesarean delivery. Two female neonates were delivered without complications and in good condition. The Apgar scores of both newborns were 10/10/10; the umbilical arterial pH of twin A was 7.262 and that of twin B was 7.368. Fig. 1b shows the placenta with 2 amniotic sacs, the centrally inserted umbilical cord of twin A, and the velamentously inserted umbilical cord of twin B, with 1 umbilical artery passing the edge of the amniotic sac of twin A.In the present case, the presence of vasa previa was demonstrated by digitally compressing the umbilical cord with consequent reflex bradycardia. This umbilical artery belonged to twin B, while the presenting part was the head of twin A.
