A new solid polymer electrolyte based on semi‐interpenetrating polymer networks (semi‐IPN) of crosslinked poly(glycidyl methacrylate‐co‐acrylonitrile)/poly(ethylene oxide) (P(GMA‐co‐AN)/PEO) was synthesized with diethylenetriamine (DETA) as the crosslinking agent and characterized. Fourier transform infrared spectroscopy (FTIR) spectra suggested the formation of semi‐IPN structure by crosslinking and revealed the interactions of Li+ ions with both the ether oxygen in PEO chain and the nitrogen atom in AN segments. Differential scanning calorimetry (DSC) and X‐ray diffraction pattern (XRD) measurements showed that crystallization of the semi‐IPN polymer electrolyte was greatly impeded. Measurement of mechanical properties revealed that tensile strength of the polymer electrolyte was increased after crosslinking. Results of electrochemistry tests suggested that the new polymer electrolyte exhibited a high‐ionic conductivity (10−4 S/cm) at room temperature, and an Arrhenius‐like behavior of the conductivity was observed. And the semi‐IPN polymer electrolyte with less content of PEO exhibited lower ion conductivity. © 2008 Wiley Periodicals, Inc. J Appl Polym Sci, 2008

Objective: An evolving challenge for obstetrician is to better define normal and abnormal fetal neurological function in utero in order to better predict antenatally which fetuses are at risk for adverse neurological outcome. Patients and methods: Prenatal neurological assessment in high-risk fetuses using four-dimensional ultrasound applying the recently developed Kurjak antenatal neurodevelopmental test (KANET). Postnatal neurological assessment was performed using Amiel Tison's neurological assessment at term (ATNAT) for all live-borns and general movement (GM) assessment for those with borderline and abnormal ATNAT. Results: Inclusion criteria were met by 288 pregnant women in four centers of whom 266 gave birth to a live-born baby. It was revealed that 234 fetuses were neurologically normal, 7 abnormal and 25 borderline. Out of 7 abnormal fetuses ATNAT was borderline in 5 and abnormal in 2, whereas GM assessment was abnormal in 5 and definitely abnormal in 2. Out of 25 KANET borderline fetuses, ATNAT was normal in 7, borderline in 17 and abnormal in 1, whereas the GM

The birth of neonates at the limits of viability, or periviability, poses numerous challenges to health care providers and to systems of care, and the care of these pregnancies and neonates is fraught with ethical controversies. This statement summarizes the ethical principles involved in the care of periviable pregnancies and neonates, and provides expert clinical opinion about the numerous challenges posed by this problem around the world. Topics addressed include a summary of the published experience, an ethical framework, translating neonatal outcome data to the obstetric arena, management as a trial of intervention, referral to tertiary centers, neonatal resuscitation, cesarean delivery for fetal indication, and limits on life-sustaining neonatal treatment.

In Romania, HSV-2 seroprevalence was higher in women than men, and was within European limits and lower than that in Africa and the USA. In contrast, HSV-1 seroprevalence was generally higher than that previously recorded in similarly aged populations in Western Europe.

EPSN increases with the gestational age and predicts SPB in asymptomatic pregnant women.
