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...

We introduce the principle of robust ordinal regression to group decision. We consider the main multiple criteria decision methods to which robust ordinal regression has been applied, i.e., UTA and GRIP methods, dealing with choice and ranking problems, UTADIS , dealing with sorting (ordinal classification) problems, and ELECTRE , being an outranking method applying robust ordinal regression to...

According to PSM, each station must announce traffic before its transmission. PSM requires for this purpose a rather large handshaking period to complete the required announcements. This functional behavior puts a heavy constraint on the size of the announcement period and consequently on throughput, delay and more importantly on power consumption. This paper proposes an optimization of some fu...

AIM The evaluation of the uterine artery recanalization rate and color Doppler parameters during follow-up after bilateral uterine artery ligation (BUAL) for postpartum hemorrhage (PPH) related to uterine atony. MATERIAL AND METHOD A total of 40 female patients who underwent BUAL for PPH related to uterine atony and 96 females who gave birth without complication at Hatay Obstetrics and Gyneco...

OBJECTIVE To compare cardiac function, systemic hemodynamics and preload reserve of women with increased (cases) and normal (controls) uterine artery (UtA) pulsatility index (PI) at 22-24 weeks of gestation. MATERIALS AND METHODS A prospective cross-sectional study of 620 pregnant women. UtA blood flow velocities were measured using Doppler ultrasonography, and PI was calculated. Mean UtA PI ...

The spermatozoa of Uta stansburiana and Urosaurus ornatus show the following squamate autapomorphies: a single perforatorium extending anteriorly from the apical tip of the paracrystalline subacrosomal cone; the presence of an epinuclear electron lucent region; intermitochondrial dense bodies; and the fibrous sheath extending into the midpiece. The acrosome vesicle is flattened and concentrical...

OBJECTIVES To evaluate the performance of screening for all stillbirths and those due to impaired placentation and unexplained or other causes using a combination of maternal factors, fetal biometry and uterine artery pulsatility index (UtA-PI) at 19-24 weeks' gestation and to compare this performance with that of screening by UtA-PI alone. METHODS This was a prospective screening study of 70...

Objective. To elaborate curves of longitudinal reference intervals of pulsatility index (PI) and systolic velocity (SV) for uterine (UtA), umbilical (UA), and middle cerebral arteries (MCA), in low risk pregnancies. Methods. Doppler velocimetric measurements of PI and SV from 63 low risk pregnant women between 16 and 41 weeks of gestational age. Means (±SD) for intervals of gestational age and ...
