Conclusions: Our findings indicate that the severity of hypoxic changes and oxidative DNA damage are greater in the placenta
of women with early-onset preeclampsia, and that the prolonged preeclamptic conditions may reduce placental blood flow, ultimately leading to FGR.”
“An optofluidic maskless photopolymerization process was developed for in situ negatively charged nanoporous hydrogel [poly-AMPS (2-acrylamido-2-methyl-1-propanesulfonic acid)] fabrication. The optofluidic maskless lithography system, which NU7441 DNA Damage inhibitor combines a high power UV source and digital mirror device, enables fast polymerization of arbitrary shaped hydrogels in a microfluidic device. The poly-AMPS hydrogel structures were positioned near the intersections of two micro-channels, and were used Selinexor molecular weight as a cation-selective filter for biological sample preconcentration. Preconcentration dynamics as well
as the fabricated polymer shape were analyzed in three-dimensions using fluorescein sample and a confocal microscope. Finally, single-stranded DNA preconcentration was demonstrated for polymerase chain reaction-free signal enhancement. (C) 2010 American Institute of Physics. [doi:10.1063/1.3516037]“
“Objective: The objective was to ascertain clinicians’ opinions and current management with isolated (no concomitant morbidity) intrauterine growth restriction (IUGR). Methods: Members of the Central Association of Obstetricians and Gynecologists (CAOG) were surveyed. We considered consensus
to be agreement among 90% of the respondents. Results: The response rate was 36% (137/385). Among the 21 questions on the topic, the only consensus was that none of the respondents informed women of the recurrence rate of IUGR. There was variance in what constitutes IUGR as well as practice patterns for detection and management of suboptimal growth. Ten (7%) of the respondents had at least one litigation involving management of IUGR. Responses from 87 general obstetrician-gynecologists varied significantly from that of BAY 73-4506 33 maternal-fetal medicine (MFM) subspecialists for 48% (10/21) of the survey questions (p < 0.05). Conclusions: There is large practice variation in detection and management of isolated IUGR. This stresses the need for additional studies and a national guideline on its management.”
“This paper reports using femtosecond laser marker to fabricate the three-dimensional interior microstructures in one closed flow channel of plastic substrate. Strip-like slots in the dimensions of 800 mu m X 400 mu m X 65 mu m were ablated with pulse Ti:sapphire laser at 800 nm (pulse duration of similar to 120 fs with 1 kHz repetition rate) on acrylic slide. After ablation, defocused beams were used to finish the surface of microstructures. Having finally polished with sonication, the laser fabricated structures are highly precise with the arithmetic roughness of 1.5 and 4.5 nm.
