As per the 2018 GLOBOCAN database, Asia accounted for 48.7% (637,761) of new gynecologiccancer cases and 50.1% (305,000) of gynecologic cancer deaths [1]. Recognizing the distinctdifferences in genetic background, cancer epidemiology, disease characteristics, and socio-cultural environment between Asian and non-Asian women, it is noteworthy that much ofthe experimental evidence guiding clinical gynecologic oncology practices has historicallybeen drawn from studies in Western populations. Established in 2008, the Asian Society ofGynecologic Oncology (ASGO) ser ves as a key organization in Asia, dedicated to advancingthe study, prevention, and treatment of gynecological cancer through scientific exchange,regional/international collaboration, educational initiatives, and fostering camaraderieamong its members [2]. Presently, ASGO boasts members from over 10 countries in Asia. Building on the success of the previous meetings held in Tokyo (2009) [3], Seoul (2011)[4], Kyoto (2013) [5], Seoul (2015) [6], Tokyo (2017) [7], Incheon (2019) [8], and Bangkok(2021) [9], the eighth Biennial Meeting of ASGO took place at the state-of-the-art HNBKInternational Convention Center in Taipei, Taiwan, from December 01 to 03, 2023. Theoverarching theme for this event was “Reunion to Overcome Gynecologic Cancer in Asia.”Notably, due to the impact of the coronavirus disease 2019 pandemic in 2021, the meetingwas transformed into a hybrid format. This gathering marked a significant milestone as thefirst in-person Pan-Asia meeting focused on gynecological cancer following the pandemic. Additionally, it is worth highlighting that this was the inaugural ASGO meeting held outsideof Korea and Japan, underscoring the broadening geographical scope and global impactof the conference. Professor Peng-Hui Wang and Jae-Weon Jim chaired the organizingcommittee. ASGO 2023 witnessed the participation of 633 attendees from 17 countries,featuring 152 honored speakers and chairs from 12 countries. The event included 44 oral/surgical video presentations and 187 poster presentations, covering a diverse range ofscientific topics, from fundamental principles of gynecological cancer care to advanced, high-technology practices rooted in cutting-edge research (Table 1).

Background/Aims: Real-world studies assessing the effectiveness and safety of sofosbuvir/velpatasvir (SOF/VEL) plus ribavirin (RBV) for Child-Pugh B/C hepatitis C virus (HCV)-related cirrhosis are limited. Methods: We included 107 patients with Child-Pugh B/C HCV-related cirrhosis receiving SOF/VEL plus RBV for 12 weeks in Taiwan. The sustained virologic response rates at off-treatment week 12 (SVR<sub>12</sub>) for the evaluable population (EP), modified EP, and per-protocol population (PP) were assessed. The safety profiles were reported. Results: The SVR<sub>12</sub> rates in the EP, modified EP and PP were 89.7% (95% confidence interval [CI], 82.5-94.2%), 94.1% (95% CI, 87.8-97.3%), and 100% (95% CI, 96.2-100%). Number of patients who failed to achieve SVR<sub>12</sub> were attributed to virologic failures. The SVR<sub>12</sub> rates were comparable regardless of patient characteristics. One patient discontinued treatment because of adverse events (AEs). Twenty-four patients had serious AEs and six died, but none were related to SOF/VEL or RBV. Among the 96 patients achieving SVR<sub>12</sub>, 84.4% and 64.6% had improved Child-Pugh and model for endstage liver disease (MELD) scores. Multivariate analysis revealed that a baseline MELD score ≥15 was associated with an improved MELD score of ≥3 (odds ratio, 4.13; 95% CI, 1.16-14.71; P=0.02). Patients with chronic kidney disease (CKD) stage 1 had more significant estimated glomerular filtration rate declines than patients with CKD stage 2 (-0.42 mL/min/1.73 ㎡/month; P=0.01) or stage 3 (-0.56 mL/min/1.73 ㎡/month; P<0.001). Conclusions: SOF/VEL plus RBV for 12 weeks is efficacious and well-tolerated for Child-Pugh B/C HCV-related cirrhosis. (Clin Mol Hepatol 2021;27:575-588)

The HAP complex has been found in many eukaryotic organisms. HAP recognizes the CCAAT box present in the promoters of 30% of all eukaryotic genes. The HAP complex consists of three subunits - HAP2, HAP3 and HAP5. In this paper, we report the biological function of the AtHAP3b gene that encodes one of the HAP3 subunits in Arabidopsis. Compared with wild-type plants, hap3b-1 and hap3b-2 mutants exhibited a delayed flowering time under long-day photoperiod conditions. Moreover, the transcription levels of FT were substantially lower in the mutants than in the wild-type plants. These results imply that AtHAP3b may function in the control of flowering time by regulating the expression of FT in Arabidopsis. In a subsequent study, AtHAP3b was found to be induced by osmotic stress. Under osmotic stress conditions, the hap3b- 1 and hap3b-2 mutants flowered considerably later than the wild-type plants. These results suggest that the AtHAP3b gene plays more important roles in the control of flowering under osmotic stress in Arabidopsis.

The present systematic review and meta-analysis was conducted to assess any association between breastfeeding and the risk of ovarian cancer. A systematic search of published studies was performed in PUBMED and EMBASE and by reviewing reference lists from retrieved articles through March 2013. Data extraction was conducted independently by two authors. Pooled relative risk ratios were calculated using random-effect models. Totals of 5 cohort studies and 35 case-control studies including 17,139 women with ovarian cancer showed a 30% reduced risk of ovarian cancer when comparing the women who had breastfed with those who had never breastfed (pooled RR = 0.70, 95% CI: 0.64-0.76; p = 0.00), with significant heterogeneity in the studies (p = 0.00; I2 = 76.29%). A significant decreasd in risk of epithelial ovarian cancer was also observed (pooled RR = 0.68, 95% CI: 0.61-0.76). When the participants were restricted to only parous women, there was a slightly attenuated but still significant risk reduction of ovarian cancer (pooled RR = 0.76, 95% CI: 0.69-0.83). For total breastfeeding duration, the pooled RRs in the < 6 months, 6-12 months and > 12 months of breastfeeding subgroups were 0.85 (95% CI: 0.77-0.93), 0.73 (95% CI: 0.65-0.82) and 0.64 (95%CI: 0.56-0.73), respectively. Meta-regression of total breastfeeding duration indicated an increasing linear trend of risk reduction of ovarian cancer with the increasing total breastfeeding duration (p = 0.00). Breastfeeding was inversely associated with the risk of ovarian cancer, especially long-term breastfeeding duration that demonstrated a stronger protective effect.
Photonic Microcavity-Enhanced Magnetic Plasmon Resonance of Metamaterials for Sensing Applications
Chen, Jing,Peng, Cheng,Qi, Shibin,Zhang, Qian,Tang, Chaojun,Shen, Xueyang,Da, Haixia,Wang, Lianhui,Park, Gun-Sik IEEE 2019 IEEE photonics technology letters Vol.31 No.2
<P>We first investigate numerically photonic microcavity-enhanced magnetic plasmon (MP) resonance in metamaterials for high-quality refractive index sensing. The metamaterials consist of a top periodic array of U-shaped metallic split-ring resonators (SRRs), a middle dielectric layer, and a bottom metallic backed plate. The top metallic SRRs that are placed at about Bragg distance above the bottom metallic plate constitute a photonic microcavity. Because the MP resonance excited in metallic SRRs is coupled to the photonic microcavity mode supported by the photonic microcavity, the radiative damping of the MP resonance is strongly reduced, and consequently, its linewidth is decreased dramatically. Benefiting from the narrow linewidth, large modulation depth, and giant magnetic field enhancement at the MP resonance, the cavity-coupled metamaterial sensor has very high sensitivity ( <TEX>$\text {S}= 400$</TEX> nm/RIU and <TEX>$\text {S}^{\ast } = 26$</TEX>/RIU) and figure of merit ( <TEX>$\text {FOM}= 33$</TEX> and FOM* = 4215), which suggests that the proposed metamaterials have potential in applications of plasmonic biosensors.</P>
Research on Fault Diagnosis of Wind Power Generator Blade Based on SC-SMOTE and kNN
Cheng Peng,Qing Chen,Longxin Zhang,Lanjun Wan,Xinpan Yuan 한국정보처리학회 2020 Journal of information processing systems Vol.16 No.4
Because SCADA monitoring data of wind turbines are large and fast changing, the unbalanced proportion of data in various working conditions makes it difficult to process fault feature data. The existing methods mainly introduce new and nonrepeating instances by interpolating adjacent minority samples. In order to overcomethe shortcomings of these methods which does not consider boundary conditions in balancing data, an improved oversampling balancing algorithm SCSMOTE (safe circle synthetic minority oversampling technology) is proposed to optimize data sets. Then, for the balanced data sets, a fault diagnosis method based on improvedknearest neighbors (kNN) classification for wind turbine blade icing is adopted. Compared with the SMOTE algorithm, the experimental results show that the method is effective in the diagnosis of fan blade icing fault and improves the accuracy of diagnosis.

<P><B>Abstract</B></P><P>Early and differential diagnosis of Alzheimer's disease (AD) is a problem that puzzled many doctors. Reliable markers in easy‐assembling samples are of considerable clinical diagnostic value. In this work, laser Raman spectroscopy (LRS) was developed a new method that potentially allows early and differential diagnosis of AD from the platelet sample. Raman spectra of platelets isolated from different ages of AD transgenic mice and non‐transgenic controls were collected and analyzed. Multilayer perceptron networks (MLP) classification method was used to classify spectra and establish the diagnostic models. For differential diagnosis, spectra of platelets isolated from AD, Parkinson’s disease (PD) and vascular dementia (VD) mice were also discriminated. Two notable spectral differences at 740 and 1654 cm<SUP>–1</SUP> were revealed in the mean spectrum of platelets isolated from AD transgenic mice and the controls. MLP displayed a powerful ability in the classifying of early, advanced AD and the control group, and in differential diagnosis of PD and advanced AD, as well as VD and advanced AD. The results suggest that platelet detecting by LRS coupled with MLP analysis appears to be an easy and accurate method for early and differential diagnosis of AD. This technique could be rapidly promoted from laboratory to the hospital. (© 2011 by Astro Ltd., Published exclusively by WILEY‐VCH Verlag GmbH & Co.
