OBJECTIVE To analyze the clinical presentation of perineal endometriosis and evaluate its treatment. METHODS Clinical data were analyzed from the records of 36 patients with perineal endometriosis who were operated on between 1983 and 2007 at Peking Union Medical College Hospital, and followed up for 0.5 to 14 years. RESULTS The incidence of perineal(More)
INTRODUCTION Recent years have seen continuous reports about the successful reconstruction of numerous organs with the application of tissue-engineering techniques. Thus, we assess the outcomes for vagina reconstruction using tissue-engineered biological material, which we suggested previously as an ideal graft for vaginoplasty. AIM To evaluate the(More)
P-type ZnO nanowires with silver (Ag) doping were synthesized via a chemical vapor deposition process. The incorporation of Ag was confirmed by selected-area energy-dispersive x-ray spectroscopy. The formation of ac-ceptor states was demonstrated by temperature and exci-tation power-dependent photoluminescence measurements. Characterization of field-effect(More)
—A nonplanar Flash memory architecture with ul-trahigh-density (∼1.5 × 10 12 cm −2) NiSi nanocrystals (NCs) as the floating gate is demonstrated using a triangular-shaped Si nanowire array as the memory transistor channel. The memory device shows good programming, erasing, and retention characteristics. This result suggests that nonplanar devices can extend(More)
OBJECTIVES The aim of this study was to evaluate the efficacy and safety with gonadotropin-releasing hormone agonist (GnRHa) combined with a levonorgestrel-releasing intrauterine system or an aromatase inhibitor (letrozole) in young women with well-differentiated early endometrial carcinoma (EC) and complex atypical hyperplasia (CAH). METHODS We performed(More)
Ovary benign clear cell adenofibroma (CCAF) is extremely rare. Here, we reported a 38-year-old woman with CCAF who was given sequential cyclic hormone replacement therapy for eight years due to premature ovarian failure (POF). At operation, we found adenofibromas in both ovaries and well encapsulated. The cut surface was cystic and solid in appearance, and(More)
Strong room-temperature ferromagnetism is demonstrated in single crystalline Mn-doped ZnO grown by molecular beam epitaxy. With a low Mn concentration of 2 Â 10 19 cm À3 , Mn-doped ZnO films exhibited room-temperature ferromagnetism with a coercivity field larger than 200 Oe, a large saturation moment of 6 l B /ion, and a large residue moment that is $70%(More)
Discrete NiSi nanocrystals were synthesized by rapid thermal oxygen annealing of very thin Si/Ni/Si films on a SiO 2 tunneling layer. They were used to fabricate metal–oxide–semiconductor capacitor memory. Electrical properties of the memory device such as programming, erasing and retention were characterized and good performance was achieved.
Di-block copolymer synthesized Co/Al 2 O 3 core-shell nanocrystal (NC) capacitors were fabricated in order to study the temperature-dependent electron transport. The capacitance-voltage memory window is shown to increase proportionally with the substrate temperature, saturating at 3.5 V, at 175 C. At elevated operating temperatures, the tunneling of(More)
—A TiSi 2 nanocrystal (NC) memory was fabricated. TiSi 2 NCs were synthesized on SiO 2 by annealing Ti covered Si NCs. Compared to the reference Si NC memory, both experiment and simulation results show that TiSi 2 NC memory exhibits larger memory window, faster writing and erasing, and longer retention lifetime as a result of the metallic property of the(More)
