Background: Ovarian cysts in pregnancy are common and are usually small benign functional cysts (corpus luteum and theca-lutein cysts) that usually resolve spontaneously between 14 and 16 weeks of gestation. However, large ovarian cysts are rare in pregnancy, with an incidence of 0.2% - 2%, and most of them are benign. The first-line diagnostic modality is ultrasonography. Complications of ovarian cysts in pregnancy include miscarriage, ovarian torsion, cyst rupture, etc. Laparotomy is the treatment modality commonly used in our setting, and histopathologic diagnosis is important for the prognosis of the treatment. Case Presentation: MC is a 32-year-old G3P2002 married housewife of the Bakweri tribe who was referred to our department because of progressive abdominal discomfort and shortness of breath for 1 month’s duration. Her medical history is consistent with two normal vaginal deliveries at term and the use of implants (for contraception) until one month prior to the index pregnancy. Her booking visit was at 16 weeks gestation at a primary (missionary) healthcare facility, and she underwent ultrasonography and was diagnosed with a singleton viable intrauterine pregnancy and a simple septate cystic mass measuring 17 cm situated on top of the uterus, appearing to originate from the left ovary. She was referred to seek the expertise of an obstetrician-gynecologist, but she came to our department at 35 weeks gestation and underwent cesarean birth at 37 weeks gestation. In the pathological review, serous cystadenoma was diagnosed, and there were no positive findings in peritoneal cytology. Conclusion: The ultrasonographic diagnosis of the huge ovarian cyst in the index case was after 16 weeks gestation because of her late booking visit at 16 weeks gestation. The index case deferred referral to the obstetrician because of a lack of finances, came to our department at 35 weeks gestation because of abdominal pain that may have resulted from a torsion of the ovarian cyst

Electrochemical performance of overlithiated Li1＋xNi0.8Co0.2O2： structural and oxidation state studies

引用

Frontiers of Materials Science 2015年第2期9卷 199-205页

作者： Roshidah RUSDI Norlida KAMARULZAMAN Kelimah elong Hashlina RUSDI Azilah ABD-RAHMAN School of Physics and Materials Faculty of Applied Sciences Universiti Teknologi MARA 40450 Shah Alam Selangor Malaysia Centre for Nanomaterials Research Institute of Science Universiti Teknologi MARA 40450 Shah Alam Selangor Malaysia Centre for Foundation Studies in Science University of Malaya 50603 Kuala Lumpur Malaysia School of Chemistry and Environment Faculty of Applied Sciences Universiti Teknologi MARA 40450 Shah Alam Selangor Malaysia

Pure, layered compounds of overlithiated Li1＋xNi0.8Co0.2O2（x = 0.05 and 0.1） were successfully prepared by a modified combustion method. XRD studies showed that cell parameters of the material decreased with increasing the lithium content. SEM revealed that the morphology of particles changed from rounded polyhedral-like crystallites to sharp-edged polyhedral crystals with more doped lithium. EDX showed that the stoichiometries of Ni and Co agrees with calculated synthesized values. Electrochemical studies revealed the overlithiated samples have improved capacities as well as cycling behavior. The sample with x = 0.05 shows the best performance with a specific capacity of 113.29 mA.h.g-1 and the best capacity retention of 92.2% over 10 cycles. XPS results showed that the binding energy of Li ls is decreased for the Li doped samples with the smallest value for the x = 0.05 sample, implying that Li＋ ions can be extracted more easily from Li1.05Ni0.8Co0.2O2 than the other stoichiometries accounting for the improved performance of the material. Considerations of core level XPS peaks for transition metals reveal the existence in several oxidation states. However, the percentage of the＋3 oxidation state of transition metals for the when x = 0.1 is the highest and the availability for charge transition from the ＋3 to＋4 state of the transition metal during deintercalation is more readily available.

Background: Cervical cancer (CC) is one of the most frequent cancers and the leading cause of death from gynecological cancer in Low and middle income countries, Cameroon inclusive. Surgery is the primary treatment modality when the disease is diagnosed at early stage. Radical hysterectomy in cervical cancer has not been evaluated in recent years in Cameroon. The purpose of this study is thus to evaluate the epidemiological and clinical features and short term outcomes of patients who underwent surgery. Patients and methods: This retrospective study was conducted at the Douala Gynaeco-obstetric and Pediatric Hospital and the Douala General Hospital. Cervical cancer patients who underwent Radical hysterectomy between January 2015 and December 2020 were included. A pre-established data collection tool was used to record socio-demographic, clinical and outcomes information from patients’ files;additional outcome information was obtained from phone calls. Descriptive analysis was done using the SPSS version 26. Bivariate analysis was used to determine associations between disease and patients characteristics and occurrence of adverse postoperative outcome. P value of 0.05 was considered. Results: Sixty one patients were enrolled. Their ages ranged from 33 to 74 years with a mean age of 51.95 ± 10.29 years. Over 85% of women were married, 65.57% were unemployed and 86.88% were multiparous. Only 28% had never done cervical cancer screening. Most patients had stage IB1 to IB2 stage disease (57.1%). Less than 9% underwent radical hysterectomy and 8 of those (13.11%) suffered intraoperative complications. Twenty-five patients (40.98%) presented immediate and short term complications. There was no significant association between the disease or patients’ characteristics and adverse outcomes. Conclusion: Cervical cancer patients are relatively young in our settings and only 9% of them reach the hospital at early stage. Postoperative adverse outcomes rate is higher than that rep

考虑到点云数据具有线性分布和密度不均匀的特点,以及现有复杂场景点云分类方法中缺少对非局部空间上下文信息的有效利用,提出了一种改进的空间上下文点云分类方法。该方法在提取点云数据顾及曲率的自适应邻域的基础上,首先估算点云局部特征与依赖性空间上下文,并基于超级体素提取分布性空间上下文,最后采用高阶条件随机场模型,实现对点云数据的自动分类,避免了利用单一点云局部特征分类的局限性。试验结果表明,本文方法能够有效提高点云数据地物分类精度。
