Conservative therapy with metformin plus megestrol acetate for endometrial atypical hyperplasia
Weiwei Shan,Chao Wang,Zhenbo Zhang,Chao Gu,Chengcheng Ning,Xuezhen Luo,Qiongjie Zhou,Xiaojun Chen 대한부인종양학회 2014 Journal of Gynecologic Oncology Vol.25 No.3
Objective: To compare the efficacy of metformin plus megestrol acetate (MA) with that of MA alone for treating endometrial atypical hyperplasia (EAH). Methods: This pilot study included 16 EAH patients who met at least one metabolic syndrome (MS) criterion and received either adjunctive metformin plus MA (MET group) or MA monotherapy (MA group). Each patient in the MA group received 160 mg of MA daily, whereas patients in the MET group received the same dose of MA plus 0.5 g of metformin thrice daily. Treatment response was assessed by histological examination of dilation and curettage specimens obtained after 12 weeks of therapy. Results: Each group had eight patients, and half of the patients in each group were diagnosed with MS. The complete response (CR) rate was 75% (6/8) in the MET group and 25% (2/8) in the MA group (p=0.105). Complications of MS did not affect the response rates in either group. In the MET group, 75% (3/4) of the patients had CR in the presence or absence of MS. In the MA group, 50% (2/4) of the patients with MS had CR, whereas no patient without MS had CR. No irreversible toxicities were observed. Conclusion: Metformin plus MA may be a potential alternative therapy for treating EAH, and the MS status of patients may have no effect on the efficacy of metformin plus MA therapy.

Future wireless network aims to integrate different radio access networks (RANs) to provide a seamless access and service continuity. In this paper, a new resource denotation method is proposed in the WLAN and LTE heterogeneous networks based on a concept of spectral bandwidth mapping. This method simplifies the denotation of system resources and makes it possible to calculate system residual capacity, upon which an economic model-based network selection algorithm is designed in both under-loaded and over-loaded scenarios in the heterogeneous networks. The simulation results show that this algorithm achieves better performance than the utility function-based access selection (UFAS) method proposed in [12] in increasing system capacity and system revenue, achieving load balancing and reducing the new call blocking probability in the heterogeneous networks.

A management strategy for solar panel - battery - super capacitor hybrid energy system in solar car
Bin Wu,Fang Zhuo,Fei Long,Weiwei Gu,Yang Qing,YanQin Liu 전력전자학회 2011 ICPE(ISPE)논문집 Vol.2011 No.5
This paper presents an application of solar energy - battery - super-capacitor hybrid energy storage system in solar electric vehicles. The key point is the proposed energy management control algorithm. The entire system consists of a solar panel, a boost converter, a battery, a super capacitor, a bi-directional DC/DC converter, and a brushless DC motor. This paper gives the details of the control strategy to cooperate the three energy sources or storage devices: solar panel, battery and super capacitor. A hysteretic control algorithm for battery charging by solar panel is given. A novel control method for bi-directional DC/DC is proposed to keep the battery discharging current within a certain limit and make full use of super capacitor. The switching transient between super-capacitor charging mode and discharging mode is also presented. Both simulation and experimental results demonstrate the effectiveness of the proposed strategy.

The genome of the cucumber, Cucumis sativus L.
Huang, Sanwen,Li, Ruiqiang,Zhang, Zhonghua,Li, Li,Gu, Xingfang,Fan, Wei,Lucas, William J,Wang, Xiaowu,Xie, Bingyan,Ni, Peixiang,Ren, Yuanyuan,Zhu, Hongmei,Li, Jun,Lin, Kui,Jin, Weiwei,Fei, Zhangjun,Li Nature Publishing Group 2009 Nature genetics Vol.41 No.12
Cucumber is an economically important crop as well as a model system for sex determination studies and plant vascular biology. Here we report the draft genome sequence of Cucumis sativus var. sativus L., assembled using a novel combination of traditional Sanger and next-generation Illumina GA sequencing technologies to obtain 72.2-fold genome coverage. The absence of recent whole-genome duplication, along with the presence of few tandem duplications, explains the small number of genes in the cucumber. Our study establishes that five of the cucumber's seven chromosomes arose from fusions of ten ancestral chromosomes after divergence from Cucumis melo. The sequenced cucumber genome affords insight into traits such as its sex expression, disease resistance, biosynthesis of cucurbitacin and 'fresh green' odor. We also identify 686 gene clusters related to phloem function. The cucumber genome provides a valuable resource for developing elite cultivars and for studying the evolution and function of the plant vascular system.
