insulin resistance (HOMA-IR) indices were significantly associated with maternal testosterone levels (r = 0.31, r = -0.37 and r = 0.35 respectively, p <= 0.05 for all). Among male offspring, a positive association between maternal and fetal testosterone levels was observed (r = 0.43, p <= 0.05). Testosterone levels were higher in the cord blood of newborns from insulin-resistant mothers compared to newborns from insulin-sensitive mothers (0.48 +/- 0.36 nmol/L vs. 0.29 +/- 0.18 nmol/L p <= 0.05). No difference was observed in mRNA abundance or protein expression of placental steroidogenic enzymes according to the degree of maternal insulin resistance. Conclusion: Our results demonstrate a possible association between fetal and maternal androgen concentrations in relationship with insulin resistance.”
“A microfluidic dynamic fluorescence-activated
interface control system was developed for lab-on-a-chip applications. The system consists of a straight rectangular microchannel, a fluorescence excitation source, a detection sensor, a signal conversion circuit, and a high-voltage feedback system. Aqueous NaCl as conducting fluid and aqueous glycerol as nonconducting fluid were introduced to flow side by side into the straight rectangular microchannel. Fluorescent dye was added to the aqueous NaCl to work as a signal representing the interface position. Automatic FAK inhibitor control of the liquid interface was achieved by controlling the electroosmotic Y-27632 purchase effect that exists only in the conducting fluid using a high-voltage feedback system. A LABVIEW program was developed to control the output of high-voltage power supply according the actual
interface position, and then the interface position is modified as the output of high-voltage power supply. At last, the interface can be moved to the desired position automatically using this feedback system. The results show that the system presented in this paper can control an arbitrary interface location in real time. The effects of viscosity ratio, flow rates, and polarity of electric field were discussed. This technique can be extended to switch the sample flow and droplets automatically.

“Objective: To determine amniotic fluid soluble Toll-like receptor 2 (sTLR2) levels in PPROM according to the presence of microbial invasion of the amniotic cavity (MIAC), histological chorioamnionitis (HCA), and both these conditions. To test the cutoff level of 222.7 ng/mL, as proposed in our previous study, in order to distinguish women with both MIAC and HCA. Methods: 169 women with a gestational age between 24+0 and 36+6 weeks were included in a prospective cohort study. Amniocenteses were performed, and sTLR2 in the amniotic fluid were determined using ELISA. Results: Women with MIAC had higher sTLR2 levels (median 113.
