We evaluated the effect of early breast-feeding and prenatal education of breast- feeding in maintenance of breast-feeding practice after delivery. Methods: Eighty two pregnant women who experienced vaginal delivery were recruited from the department of obstetrics and gynecology of a university hospital between January 2006 and October 2006. These differences among variables were determined using SPSS ver. 10.0 (SPSS Inc., Chicago, IL, USA). Follow-up telephone interviews were conducted 1 week and 4 weeks after delivery to check feeding method for baby and other complications. Results: We calculated the correlations among the pregnant women’s age, height, and weight, abortion experience, the newborn’s weight, and social factors using ANOVA. There was no statistically significant relationship between early breast-feeding and maintenance of breast-feeding practice. Conclusions: Antenatal and post- partum period education about breast-feeding is necessary for breast-feeding practice maintenance. Further studies in developing educational programs are needed.展开更多

At the same time, field-effect transistor （FET）-based biosensors have attracted great attention because they can provide highly sensitive and label-free detection. In this work we present highly sensitive, epidermal skin-type point-of-care devices with system-level integration of flexible MOS2 FET biosensors, read-out circuits, and light-emitting diode （LEDs） that enable real-time detection of prostate cancer antigens （PSA）. Regardless of the physical forms or mechanical stress conditions, our proposed high-performance MoS2 biosensors can detect a PSA concentration of 1 pg.mL-1 without specific surface treatment for anti-PSA immobilization on the MoS2 surface on which we characterize and confirm physisorption of anti-PSA using Kelvin probe force microscopy （KPFM） and tapping-mode atomic force microscopy （tm-AFM）. Furthermore, current modulation induced by the binding process was stably maintained for longer than 2-3 min. The results indicate that flexible MoS2-based FET biosensors have great potential for point-of-care diagnostics for prostate cancer as well as other biomarkers.展开更多
