This study considers the possibility of using coherence analysis for detection and measurement of synchrony (correlations) in large neural populations, applied to activities that are relatively easy to record in parallel. Mathematical analysis and computer simulations are used to examine the behavior of the coherence function between both unitary and population-aggregate activity (UTA coherence...

Unresolved transition array (UTA) is scalable to shorter wavelengths, and we demonstrate a table-top broadband emission “water window” soft x-ray source based on laserproduced plasmas. Resonance emission from multiply charged ions merges to produce intense UTAs in the 2 to 4 nm region, extending below the carbon K edge (4.37 nm). An outline of a microscope design for single-shot live cell imagi...

OBJECTIVE To investigate the potential value of combined screening by maternal characteristics and medical history (maternal factors), estimated fetal weight (EFW), uterine artery pulsatility index (UtA-PI), mean arterial pressure (MAP) and serum levels of placental growth factor (PlGF) and soluble fms-like tyrosine kinase-1 (sFlt-1) at 30-34 weeks' gestation in the prediction of delivery of sm...

Background. Poor placentation and systemic endothelial dysfunction have been identified as main events in Preeclampsia (PE). The relationship and chronology of these phenomena are important if we are to understand the pathophysiological mechanisms underlying this major clinical problem. Objectives. To compare the evolution of placentation and endothelial function in normotensive and preeclampti...

OBJECTIVE To evaluate the role of cervical length (CL) and uterine artery pulsatility index (UtA-PI) at 11+0 to 13+6 weeks as predictors of spontaneous preterm delivery (sPTD) in a Chilean population. METHODS This was a prospective study of asymptomatic women with singleton pregnancies attending for a nuchal translucency scan at 11+0 to 13+6 weeks' gestation and who underwent a transvaginal s...

The aim of the study is identification of urinary tract infections (UTI) and urinary tract anomalies (UTA) already in the perinatal period. The authors attempted to prevent serious consequences of the above conditions in the examined children. Family history data, certain conditions in pregnancy and appertaining symptoms in children were elaborated to specify selective distinctive criteria for ...

BACKGROUND The effects of epidural anaesthesia on maternal uteroplacental blood flow in the presence of uterine contractions remain unclear. The aim of our study was to evaluate the effects of epidural analgesia with bolus doses on uterine artery pulsatility index (UtA-PI) during labour. METHODS In a prospective case-control study, UtA-PI was measured during uterine contraction and relaxation...
