Abstract: Provided is a method for noninvasive prediction or diagnosis of inflammation and/or infection in amniotic fluid leaked through the cervix into the vagina to predict the concentration of inflammatory markers in the amniotic fluid inside uterus by measuring the concentration of inflammatory markers (various cytokines). Further provided is a method for prediction or diagnosis of inflammation and/or infection in amniotic fluid by measuring the concentration of markers (IL-6, IL-1? IL-8, MCP-1, GRO-?) in the amniotic fluid leaked through the cervix into the vagina in patients with premature rupture of membranes. The method can be performed more stably on pregnant women, as compared to the conventional method for prediction or diagnosis of inflammation and/or infection using invasively collected amniotic fluid.

Abstract: An active region or channel for printed, organic or plastic electronics or polymer semiconductors, such as organic field-effect transistors (OFETs), is obtained by using an enhanced inkjet drop-cast printing technique. A two-liquid system is employed to achieve the direct growth of well-oriented organic crystals at the active region of channel. High-performance electrical properties exhibiting high carrier mobility and low threshold voltage are obtained due to the proper orientation of molecules in the grown crystal in a highest mobility direction, due to the absence of grain boundaries, and due to low trap densities. The hydrophobic-hydrophilic interactions between the liquids utilized, which results in the fabrication of low-cost and mass-producible printable electronic devices for applications in flexible displays, electronic signages, photovoltaic panels, membrane keyboards, radio frequency identification tags (RFIDs), electronic sensors, and integrated electronic circuits.
