Background: In Vitro Fertilization/Intracytoplasmic Sperm Injection (IVF/ICSI) represents the final step in the management of Polycystic Ovarian Syndrome (PCOS). Our objective was to study the association between PCOS phenotypes and IVF/ICSI results in women admitted to Gynaecological Endoscopic Surgery and Human Reproductive Teaching Hospital (CHRACERH). Material and Method: We carried out a cohort study with historical-prospective data collection over a period of seven years (January 2016 to March 2023) at Chracerh. PCOS patients were subdivided into 4 subgroups A, B, C and D. Results: We recruited 128 patients including 64 PCOS patients divided into four phenotypes and 64 non-PCOS patients constituting the control group. Phenotype D without hyperandrogenism had used the lowest dose of gonadotropins, i.e. 1939.7 ± 454.3 IU, and had produced a greater quantity of estradiol on the day ovulation was triggered (6529.8 ± 4324.8 ng/ml). The average number of punctured follicles and mature oocytes were higher in the phenotype D group. Ovarian hyperstimulation syndrome (OHSS) occurred mainly in phenotype D (3/35), with an estimated prevalence of 2.3%. The fertilization rate seemed lower in the hyperandrogenic phenotypes A, B, C compared to the group without hyperandrogenism without significant difference (p = 0.461). The biological pregnancy rate and live birth rate were comparable between the different groups. Conclusion: Phenotype D used less dose of gonadotropins. Biological pregnancy and live birth rates were comparable between the different phenotypes.

AIM： To evaluate the effect of ranitidine on gastric mucosal changes and on GI bleeding in long distance runhers. METHODS： Twenty-four long distance runners （M： 16, F： 8, age： 18.2＋ 1.5 years） participated in this study. A symptom questionnaire, stool hemoccult test, and upper gastrointestinal （GI） endoscopy were performed on the subjects prior to the study. The subjects took oral ranitidine （150 mg, b.i.d.） for two weeks. The upper GI endoscopy and stool Hemoccult tests were repeated after the treatment. RESULTS： Twenty-two of the 24 runners had at least one upper G1 mucosal lesion before the medication. The Endoscopic improvements were seen in eleven of the 14 cases of erosive gastritis and four of the 5 cases of esophagitis. Six subjects were Heine occult positive prior to the study, but only one was positive after the medication. CONCLUSION： Gastric mucosal lesions and GI bleeding in long distance runners seem to be associated to acidrelated factors mediated by the high level of regular running. Ranitidine seems to be and effective prophylaxis to prevent gastric mucosal lesions and GI bleeding.

DISTRIBUTIONS ON ALMOST CONTACT MANIFOLDS

Acta Mathematica Scientia 2017年第3期37卷 695-702页

作者： Hyunjoo cho National Center for Theoretical Sciences Mathematics Division Taipei 10617 China

It is known that any hypersurface in an almost complex space admits an almost contact manifold [11, 14]. In this article we show that a hyperplane in an almost contact manifold has an almost complex structure. Along with this result, we explain how to deter- mine when an almost contact structure induces a contact structure, followed by examples of a manifold with a closed G2-structure.

Self Localization Method Using Parallel Projection Model for Mobile Sensor in Navigation Applications

引用

Journal of Computer Science & Technology 2009年第3期24卷 588-603页

作者： Shung Han cho Yuntai Kyong Sangjin Hong We-Duke cho Department of Electrical and Computer Engineering Stony Brook University- SUNY Stony Brook NY U.S.A. Department of Electronics Engineering College of Information Technology Ajou University Suwon Korea

This paper presents a novel self localization method using parallel projection model for mobile sensor in navigation applications. The algorithm estimates the coordinate and the orientation of mobile sensor using projected references on visual image. The proposed method considers the lens non-linearity of the camera and compensates the distortion by using a calibration table. The method determines the coordinates and orientations with iterative process, which is very accurate with low computational demand. We identify various sources of error on the coordinate and orientation estimations, and present both static sensitivity analysis of the algorithm and dynamic behavior of the mobile sensor. The algorithm can be utilized in mobile robot navigation as well as positioning application where accurate self localization is necessary.
