Abstract
Cervical cancer, primarily caused by high-risk human papillomavirus (HR-HPV) types 16 and 18, is a major global health concern. Persistent HR-HPV infection can progress from reversible precancerous lesions to invasive cervical cancer, which is driven by the oncogenic activity of human papillomavirus (HPV) genes, particularly E6 and E7. Traditional screening methods, including cytology and HPV testing, have limited sensitivity and specificity. This review explores the application of p16/Ki-67 dual-staining cytology for cervical cancer screening. This advanced immunocytochemical method allows for simultaneously detecting p16 and Ki-67 proteins within cervical epithelial cells, offering a more specific approach for triaging HPV-positive women. Dual staining and traditional methods are compared, demonstrating their high sensitivity and negative predictive value but low specificity. The increased sensitivity of dual staining results in higher detection rates of CIN2+ lesions, which is crucial for preventing cervical cancer progression. However, its low specificity may lead to increased false-positive results and unnecessary biopsies. The implications of integrating dual staining into contemporary screening strategies, particularly considering the evolving landscape of HPV vaccination and changes in HPV genotype prevalence, are also discussed. New guidelines and further research are necessary to elucidate the long-term effects of integrating dual staining into screening protocols.

Abstract
Betulinic acid (BetA), a triterpenoid derivative found abundantly in the plant kingdom, has emerged as a promising candidate for promoting longevity. Many research studies have shown its antioxidant, anti-inflammatory, antiviral, and anticancer activities, making it an interesting subject for investigating its potential influence on lifespan. This study aimed to investigate the effects of BetA on longevity and the mechanisms associated with it using the fruit fly Drosophila melanogaster as the organism model. The results showed that 50 μM BetA supplementation extended the mean lifespan of fruit flies by 13% in males and 6% in females without any adverse effects on their physiology, such as fecundity, feeding rate, or locomotion ability reduction. However, 50 μM BetA supplementation failed to increase the lifespan in mutants lacking functional silent information regulator 2 (Sir2) and Forkhead box O (FoxO)-null, implying that the longevity effect of BetA is related to Sir2 and FoxO activation. Our study contributes to the knowledge in the field of anti-aging research and inspires further investigations into natural compounds such as BetA to enhance organismal healthspan.

Abstract
Nanoplastics (NPs) exposure to humans can occur through various routes, including the food chain, drinking water, skin contact, and respiration. NPs are plastics with a diameter of less than 100 nm and have the potential to accumulate in tissues, leading to toxic effects. This study aimed to investigate the neurotoxicity of polystyrene NPs on neural progenitor cells (NPCs) and hippocampal neurogenesis in a rodent model. Toxicity screening of polystyrene NPs based on their charge revealed that cationic amine-modified polystyrene (PS-NH3+) exhibited cytotoxicity, while anionic carboxylate-modified polystyrene (PS-COO-) and neutral NPs (PS) did not. NPCs treated with PS-NH3+ showed a significant reduction in growth rate due to G1 cell cycle arrest. PS-NH3+ increased the expression of cell cycle arrest markers p21 and p27, while decreasing cyclin D expression in NPCs. Interestingly, PS-NH3+ accumulated in mitochondria, leading to mitochondrial dysfunction and energy depletion, which caused G1 cell cycle arrest. Prolonged exposure to PS-NH3+ in C17.2 NPCs increased the expression of p16 and senescence-associated secretory phenotype factors, indicating cellular senescence. In vivo studies using C57BL/6 mice demonstrated impaired hippocampal neurogenesis and memory retention after 10 days of PS-NH3+ administration. This study suggests that NPs could deplete neural stem cell pools in the brain by mitochondrial dysfunction, thereby adversely affecting hippocampal neurogenesis and neurocognitive functions.

Abstract
BACKGROUND The aim of this study was to evaluate the relationship between depressed mood and gynecological cancer outcomes, identifying risk factors for cancer aggravation. METHODS This study was a retrospective analysis of gynecological cancer patients (January 2020-August 2022) at Korea University Anam Hospital using Patient Health Questionnaire-9 (PHQ-9). Patients were classified into non-depressed mood (NDM)- and depressed mood (DM)-based scores. Statistical analysis was performed using Student's t-test, chi-square test, Fisher's exact test, Kaplan-Meier analysis, and Cox regression analyzing using SPSS. RESULTS Of the 217 participants, the NDM group comprised 129 patients, and the DM group comprised 88. The two-year disease-free survival (DFS) rates showed significant differences (NDM, 93.6%; DM 86.4%; p = 0.006), but overall survival (OS) did not (p = 0.128). Patients with stage 3 or higher cancer, undergoing five or more chemotherapies, experiencing post-chemotherapy side effects, and depressed mood had an increased risk of cancer aggravation. CONCLUSIONS Appropriate treatment of depressed mood, as well as adequate treatment for advanced gynecological cancer patients, those with numerous CTx., and those with post-CTx. side effects, may contribute to reducing the risk of cancer aggravation.

Abstract
Colposcopy is the gold standard diagnostic tool for identifying cervical lesions. However, the accuracy of colposcopies depends on the proficiency of the colposcopist. Machine learning algorithms using an artificial intelligence (AI) system can quickly process large amounts of data and have been successfully applied in several clinical situations. This study evaluated the feasibility of an AI system as an assistive tool for diagnosing high-grade cervical intraepithelial neoplasia lesions compared to the human interpretation of cervical images. This two-centered, crossover, double-blind, randomized controlled trial included 886 randomly selected images. Four colposcopists (two proficient and two inexperienced) independently evaluated cervical images, once with and the other time without the aid of the Cerviray AI® system (AIDOT, Seoul, Republic of Korea). The AI aid demonstrated improved areas under the curve on the localization receiver-operating characteristic curve compared with the colposcopy impressions of colposcopists (difference 0.12, 95% confidence interval, 0.10-0.14, p < 0.001). Sensitivity and specificity also improved when using the AI system (89.18% vs. 71.33%; p < 0.001, 96.68% vs. 92.16%; p < 0.001, respectively). Additionally, the classification accuracy rate improved with the aid of AI (86.40% vs. 75.45%; p < 0.001). Overall, the AI system could be used as an assistive diagnostic tool for both proficient and inexperienced colposcopists in cervical cancer screenings to estimate the impression and location of pathologic lesions. Further utilization of this system could help inexperienced colposcopists confirm where to perform a biopsy to diagnose high-grade lesions.

Abstract
The term probiotic refers to bacteria that provide a beneficial effect to the host. Limosilactobacillus reuteri (Lactobacillus reuteri) is a probiotic isolated from human breast milk. Although L. reuteri has antimicrobial and anti-inflammatory activities occasionally linked to anti-aging effects, there are no reports of the effects of L. reuteri on longevity. This study evaluated the anti-aging effects of L. reuteri on the lifespan and physiology of Drosophila melanogaster. L. reuteri increased the mean lifespan of fruit flies significantly without reducing the reproductive output, food intake, or locomotor activity. Furthermore, the data suggested that the longevity effect of L. reuteri is mediated by the reduction of the insulin/IGF-1 signaling pathway and the action of reuterin, an antimicrobial compound produced by L. reuteri. These results show that L. reuteri can be used as a probiotic that acts as a dietary restriction mimetic with anti-aging effects.

Abstract
BACKGROUND The aim of this study is to compare the surgical outcomes of single-port laparoscopic surgery (SPLS) and single-port robotic surgery (SPRS). METHODS We retrospectively analyzed patients who underwent a hysterectomy, ovarian cystectomy, or myomectomy with SPLS or SPRS from January 2020 to July 2022. Statistical analyses were performed using the SPSS chi-square test and student's t-test. RESULTS A total of 566 surgeries including single-port laparoscopic hysterectomy (SPLH; n = 148), single-port robotic hysterectomy (SPRH; n = 35), single-port laparoscopic ovarian cystectomy (SPLC; n = 207), single-port robotic ovarian cystectomy (SPRC; n = 108), single-port laparoscopic myomectomy (SPLM; n = 12), and single-port robotic myomectomy (SPRM; n = 56). The SPRH, SPRC, and SPRM groups had a shorter operation time than the SPLS group, although the results were not statistically significant (SPRH vs. SPLH, p = 0.134; SPRC vs. SPLC, p = 0.098; SPRM vs. SPLM, p = 0.202). Incisional hernia occurred as a postoperative complication in two patients only in the SPLH group. Postoperative Hb changes were lower in the SPRC and SPRM groups than in the SPLC and SPLM groups (SPRC vs. SPLC, p = 0.023; SPRM vs. SPLM, p = 0.010). CONCLUSIONS Our study demonstrated that the SPRS had comparable surgical outcomes when compared to the SPLS. Therefore, the SPRS should be considered a feasible and safe option for gynecologic patients.

Abstract
Abstract
Background/Introduction
Signal-averaged electrocardiography (SA-ECG) is a high-resolution electrocardiography that can detect late ventricular potential, which known to be a noninvasive tool for risk stratification of sudden cardiac death (SCD) by predicting reentrant ventricular tachyarrhythmia. There is a paucity of data with SA-ECG on SCD survivors without structural heart disease, whereas majority of previous studies had been focused on post myocardial infarction survivors.
Purpose
This study assessed the clinical utility of SA-ECG as a risk stratification modality for lethal arrhythmic event in patients at risk of SCD without definite structural heart disease.
Methods
Total 629 patients who experienced or had potential risk of SCD were studied with SA-ECG. Among them, 48 patients who were found to have significant structural heart disease were excluded, except arrhythmogenic right ventricular cardiomyopathy. Major arrhythmic event (MAE) was defined as composite of all-cause death, aborted SCD, and sustained VT during any time either before visit of clinic or during follow up period. Syncope and non-sustained VT was defined as non-major arrhythmic event. SA-ECG was defined positive when fulfilling three or more criterion: (1) unfiltered QRS duration ≥114ms, (2) filtered QRS duration ≥114ms, (3) duration of terminal QRS <40uV exceeding 40ms, and (4) root mean square voltage in the terminal 40ms of ≤20ms.
Results
Among total 581 patients, 145 patients with positive SA-ECG showed higher incidence of MAE compared to patients with negative SA-ECG (21.4% vs. 6.7%, OR 3.816 [95% CI 2.208–6.597], p<0.001, Table). As the number of positive SA-ECG criteria increases, incidence of MAE tended to increase sequentially, which was markedly noted from 2 positive to 3 positive criteria (10.7% to 20.8%, p<0.001, Figure). In particular, patient with inherited arrhythmia showed higher rate of positive late potential compared to those with non-inherited arrhythmia (51.0% vs. 19.3%, p<0.001).
Conclusion
This study showed that at least 3 out of 4 diagnostic criteria in SA-ECG can independently predict lethal arrhythmic events and the positive late potential was associated with lethal arrhythmic event that leads to SCD, suggesting risk prediction for SCD using SA-ECG in patients even without structural heart disease including inherited arrhythmias.

Abstract
Abstract
Background/Introduction
Brugada syndrome (BrS) and arrhythmogenic right ventricular cardiomyopathy (ARVC) are inherited arrhythmias that may predispose to sudden cardiac arrest. Although its pathogenetic mechanisms differ, overlapping features between BrS and ARVC have been demonstrated previously. However, it remains to be determined whether genetic testing for ARVC-related gene is needed in patients with BrS.
Purpose
This study is aimed to analyze genetic profiles of BrS patients using next generation sequencing (NGS) based multigene panel including ARVC related genes.
Methods
Patients who were confirmed as BrS or clinically suspected as BrS with type 2 or 3 Brugada pattern electrocardiography were studied. Genetic testing using NGS panels (Illumina Inc., San Diego, CA, USA) included 30 genetic variants associated with inherited arrhythmia and genetic cardiomyopathy.
Results
Among the total 119 patients from BrS registry, 63 patients were confirmed as BrS and 56 patients were clinically suspected as BrS without fulfilling diagnostic criteria. One-hundred-fourteen patients (95.8%) were male, and mean age of onset was 43.6 year-old. Genetic variants were identified in 25 of 42 patients who received genetic testing. Six out of 25 patients (24.0%) showed ARVC-related genotypes (2 PKP2, 1 DSG2, 1 TMEM43, 1 JUP, and 1 DSP) (Figure 1 and Table 1). None of the patients showed structural or electrocardiographic features that fulfill diagnostic criteria of ARVC. It is notable that ARVC-related genotypes were mostly frequently accounted for BrS patients, following SCN5A and SCN10A.
Conclusion
In the clinic setting, ARVC-related genetic variants were identified in significant proportion of BrS patients, supporting that genetic testing of ARVC-overlapping is needed. This study suggests that follow-up including imaging study should be considered in BrS patients with ARVC-related genotypes to monitor disease progression as ARVC.

Abstract
BACKGROUND Although the incidence of cervical cancer has decreased since the 1980s in Korea, it remains high among the elderly women. This study evaluated the suitability of cervical cancer screening for elderly Korean women aged ≥65 years according to recommendations by the American Society of Cytopathology and American Society for Colposcopy and Cervical Pathology. METHODS We retrospectively reviewed the records of patients who underwent cervical cancer screening, followed by liquid-based Pap test, human papillomavirus (HPV) test, and colposcopic punch biopsy at two academic hospitals from May 2008 to May 2018. The participants were divided into two groups <65 and ≥65 years old. Logistic regression analysis was performed to evaluate the association between cytology tests, HPV tests and the occurrence of high-risk lesions, ≥cervical intraepithelial neoplasia2 (CIN2). RESULTS The mean patient age was 49.02 ± 15.437 (range 15-91) years. No patients aged <25 years showed atypical squamous cell-cannot exclude high grade (ASC-H), squamous cell carcinoma (SCC), or adenocarcinoma (ADC). The incidence of high-grade squamous intraepithelial lesion (HISL) (39.7%) and ≥CIN 3 (40.2%) was significantly higher in patients ≥65 years of age than in other age groups. However, patients ≥65 years showed increased HSIL and HPV negativity and ASC-H, HSIL, and HPV positivity in those with ≥CIN 2 (both p = .043). CONCLUSION Korean women aged ≥65 years should undergo cervical cancer screening. The relevance of HPV or Cytology test alone or co-test for screening should be evaluated in this population.

Abstract
Hysterectomy remains a frequent gynecologic surgery, although its rates have been decreasing. The aim of this study was to investigate whether socioeconomic status affected the risk of hysterectomy in Korean women. This prospective cohort study used epidemiologic data from 2001 to 2016, from the Korean Genomic and Epidemiology Study (KoGES). Multivariate logistic regression analyses were performed to estimate the association between household income or education level and hysterectomy. Among 5272 Korean women aged 40−69 years, 720 who had a hysterectomy and 4552 controls were selected. Variable factors were adjusted using logistic regression analysis (adjusted model). Adjusted odds ratios (aORs) for insurance type and hysterectomy were not statistically significant. The aOR was 1.479 (95% confidence interval (CI): 1.018−2.146, p < 0.05) for women with education of high school or lower compared to college or higher. Women whose monthly household income was <KRW 4,000,000 had a higher risk of undergoing hysterectomy than women whose monthly household income was ≥KRW 4,000,000 (aOR: 2.193, 95% CI: 1.639−2.933, p < 0.001). Overall, the present study elucidated that lower socioeconomic status could increase the incidence of hysterectomy. Our results indicate that the implementation of stratified preventive strategies for uterine disease in those with low education and low income could be beneficial.

Abstract
BACKGROUND Commensal microbiota live in their host with a symbiotic relationship that affects the host's health and physiology. Many studies showed that microbial load and composition were changed by aging and observed that increasing the abundance and changing the composition of commensal microbes had detrimental effects on host lifespan. We hypothesized that dysbiosis of the intestinal microbiota leads to systemic effects in aging flies as a result of the increased intestinal permeability. METHODS We used the fruit fly, Drosophila melanogaster, laboratory strains w1118, as a model system with many advantages for microbe-host studies. RESULTS The incidence of intestinal dysfunction was increased with age, and intestinal dysfunction increased the permeability of the fly intestine to resident microbes. The lifespan of flies with an intestinal barrier dysfunction was increased by removal of the microbes. Interestingly, some bacteria were also found in the hemolymph of flies with intestinal barrier dysfunction. CONCLUSION Our findings suggest the possibility that, as the host ages, there is an increase in intestinal permeability, which leads to an increased intestinal microbial load and a reduction in the host lifespan. Our data therefore indicate a connection between commensal microbes and host lifespan.

Abstract
Since the human papillomavirus (HPV) vaccine guidelines were developed by the Korean Society of Gynecologic Oncology (KSGO) in 2011, 2016, and 2019, several recent studies on the efficacy and safety of HPV vaccines in middle-aged women and men have been reported. Furthermore, there has been an ongoing debate regarding the efficacy of the HPV vaccine in women with prior HPV infection or who have undergone conization for cervical intraepithelial neoplasia (CIN). We searched and reviewed studies on the efficacy and safety of the HPV vaccine in middle-aged women and men and the efficacy of the HPV vaccine in patients infected with HPV and those who underwent conization for CIN. The KSGO updated their guidelines based on the results of the studies included in this review.

Abstract
AIM The aim of this study was to evaluate the clinical performance for detecting cervical intraepithelial neoplasia (CIN) 2 or higher lesions among available human papillomavirus infection (HPV) genotyping tests in Korea. METHODS Eligible patients visited 13 tertiary hospitals for colposcopic biopsy following cervical cytology and HPV genotyping test between January and December 2018. Baseline characteristics including age, body mass index (BMI), and parity were collected from 3798 patients. The performance of the Roche Cobas HPV 4800 was evaluated against other domestic HPV assays to detect CIN2 or higher. RESULTS A total of seven types of HPV genotyping tests were analyzed in the research institutes. A total of 1358 patients (35.8%) tested Anyplex II HPV 28 and 701 patients (18.5%) tested Cobas 4800 HPV. The overall sensitivity in the detection of CIN2 or higher was 41.5% (38.9-44.1) in patients positive for HPV 16/18. The Cobas test for HPV 16/18 was concordant with other assays evaluated for detection of CIN2 or higher and showed sensitivity of 46.6%, which was not significantly different from other assays. Although Anyplex II HPV28 (Seegene) showed slightly decreased sensitivity for detecting CIN2 or higher lesion with HPV 16/18 positive (39.8%, p < 0.05) compared to Cobas 4800, in aspect of high-risk HPV positive, Anyplex II HPV28 showed increased sensitivity (96.9%, p < 0.05). CONCLUSION The performance of the HPV genotype test that were commonly used in Korea was concordant with Cobas HPV test. Further studies are needed to evaluate the safety, efficiency, and cost-effectiveness of the various commercially available domestic HPV assays.

Abstract
AIM We examined the underlying mechanisms associated with the longevity effects of Korean mistletoe extract (KME) in Drosophila melanogaster. METHODS We measured the lifespan of sirtuin, chico and foxo mutant flies fed KME, the expression of the forkhead box O (FOXO) target genes and insulin-like peptide genes, and the localization of FOXO in flies fed the KME. RESULTS The longevity effect of KME was abolished in sirtuin, chico and foxo null mutant flies. In addition, the expression of FOXO target genes and the localization of FOXO into nuclei were increased in flies fed KME, but the expression of the insulin-like peptide genes was decreased by KME supplementation. CONCLUSIONS The results show that KME extends the fly lifespan through sirtuin-induced FOXO activation. We suggest that KME has potential use as a beneficial anti-aging and longevity supplement.

Abstract
Ionizing radiation induces biological/physiological changes and affects commensal microbes, but few studies have examined the relationship between the physiological changes induced by irradiation and commensal microbes. This study investigated the role of commensal microbes in the γ-ray irradiation-induced physiological changes in Drosophila melanogaster. The bacterial load was increased in 5 Gy irradiated flies, but irradiation decreased the number of operational taxonomic units. The mean lifespan of conventional flies showed no significant change by irradiation, whereas that of axenic flies was negatively correlated with the radiation dose. γ-Ray irradiation did not change the average number of eggs in both conventional and axenic flies. Locomotion of conventional flies was decreased after 5 Gy radiation exposure, whereas no significant change in locomotion activity was detected in axenic flies after irradiation. γ-Ray irradiation increased the generation of reactive oxygen species in both conventional and axenic flies, but the increase was higher in axenic flies. Similarly, the amounts of mitochondria were increased in irradiated axenic flies but not in conventional flies. These results suggest that axenic flies are more sensitive in their mitochondrial responses to radiation than conventional flies, and increased sensitivity leads to a reduced lifespan and other physiological changes in axenic flies.

Abstract
Due to improvements in chemotherapeutic agents, cancer treatment efficacy and cancer patient survival rates have greatly improved, but unfortunately gonadal damage remains a major complication. Gonadotoxic chemotherapy, including alkylating agents during reproductive age, can lead to iatrogenic premature ovarian insufficiency (POI), and loss of fertility. In recent years, the demand for fertility preservation has increased dramatically among female cancer patients. Currently, embryo and oocyte cryopreservation are the only established options for fertility preservation in women. However, there is growing evidence for other experimental techniques including ovarian tissue cryopreservation, oocyte in vitro maturation, artificial ovaries, stem cell technologies, and ovarian suppression. To prevent fertility loss in women with cancer, individualized fertility preservation options including established and experimental techniques that take into consideration the patient’s age, marital status, chemotherapy regimen, and the possibility of treatment delay should be provided. In addition, effective multidisciplinary oncofertility strategies that involve a highly skilled and experienced oncofertility team consisting of medical oncologists, gynecologists, reproductive biologists, surgical oncologists, patient care coordinators, and research scientists are necessary to provide cancer patients with high-quality care.

Abstract
Commensal microbes have mutualistic relationships with their host and mainly live in the host intestine. There are many studies on the relationships between commensal microbes and host physiology. However, there are inconsistent results on the effects of commensal microbes on host lifespan. To clarify this controversy, we generated axenic flies by using two controlled methods – bleaching and antibiotic treatment – and investigated the relationship between the commensal microbes and host lifespan in Drosophila melanogaster. The removal of microbes by using bleaching and antibiotic treatments without detrimental effects increased fly lifespan. Furthermore, a strain of flies colonized with a high load of microbiota showed a greater effect on lifespan extension when the microbes were eliminated, suggesting that commensal bacteria abundance may be a critical determinant of host lifespan. Consistent with those observations, microbial flora of aged fly gut significantly decreased axenic fly lifespan via an increase in bacterial load rather than through a change of bacterial composition. Our elaborately controlled experiments showed that the elimination of commensal microbes without detrimental side effects increased fly lifespan, and that bacterial load was a significant determinant of lifespan. Furthermore, our results indicate the presence of a deterministic connection between commensal microbes and host lifespan.

Abstract
Many studies utilizing animal models have revealed the genetic and pharmacogenetic modulators of the rate of organismal aging. However, finding routes for healthy aging during extended life remains one of the largest questions. With regards to an antiaging reagent, it has been shown that natural phytochemical syringaresinol (SYR) delays cellular senescence by activating sirtuin1 (SIRT1). Here, it is found that SYR treatment results in metabolic changes similar to those observed during dietary restriction (DR). The DR mimetic effects are mediated by FoxO3a-dependent SIRT1 activation and insulin/insuline growth factor-1 signaling modulation. The direct binding of SYR-FoxO3a is identified and this could partially explain the DR-like phenotype. The report gives a clue as to how the longevity gene involves the DR pathway and suggests that natural phytochemicals applied as a geroprotector mimics DR effects.

Abstract
Methionyl-tRNA synthetase (MRS) is essential for translation. MRS mutants reduce global translation, which usually increases lifespan in various genetic models. However, we found that MRS inhibited Drosophila reduced lifespan despite of the reduced protein synthesis. Microarray analysis with MRS inhibited Drosophila revealed significant changes in inflammatory and immune response genes. Especially, the expression of anti-microbial peptides (AMPs) genes was reduced. When we measured the expression levels of AMP genes during aging, those were getting increased in the control flies but reduced in MRS inhibition flies agedependently. Interestingly, in the germ-free condition, the maximum lifespan was increased in MRS inhibition flies compared with that of the conventional condition. These findings suggest that the lifespan of MRS inhibition flies is reduced due to the down-regulated AMPs expression in Drosophila.

Abstract
A coronavirus (HCoV-19) has caused the novel coronavirus disease (COVID-19) outbreak in Wuhan, China. Preventing and reversing the cytokine storm may be the key to save the patients with severe COVID-19 pneumonia. Mesenchymal stem cells (MSCs) have been shown to possess a comprehensive powerful immunomodulatory function. This study aims to investigate whether MSC transplantation improves the outcome of 7 enrolled patients with COVID-19 pneumonia in Beijing YouAn Hospital, China, from Jan 23, 2020 to Feb 16, 2020. The clinical outcomes, as well as changes of inflammatory and immune function levels and adverse effects of 7 enrolled patients were assessed for 14 days after MSC injection. MSCs could cure or significantly improve the functional outcomes of seven patients without observed adverse effects. The pulmonary function and symptoms of these seven patients were significantly improved in 2 days after MSC transplantation. Among them, two common and one severe patient were recovered and discharged in 10 days after treatment. After treatment, the peripheral lymphocytes were increased, the C-reactive protein decreased, and the overactivated cytokine-secreting immune cells CXCR3+CD4+ T cells, CXCR3+CD8+ T cells, and CXCR3+ NK cells disappeared in 3-6 days. In addition, a group of CD14+CD11c+CD11bmid regulatory DC cell population dramatically increased. Meanwhile, the level of TNF-α was significantly decreased, while IL-10 increased in MSC treatment group compared to the placebo control group. Furthermore, the gene expression profile showed MSCs were ACE2- and TMPRSS2- which indicated MSCs are free from COVID-19 infection. Thus, the intravenous transplantation of MSCs was safe and effective for treatment in patients with COVID-19 pneumonia, especially for the patients in critically severe condition.

Abstract
Aminoacyl-tRNA synthetases (ARSs), which are essential for protein translation, were recently shown to have non-translational functions in various pathological conditions including cancer. However, the molecular mechanism underlying the role of ARSs in cancer remains unknown. Here, we demonstrate that asparaginyl-tRNA synthetase (NRS) regulates Yorkie-mediated tumorigenesis by binding to the Hippo pathway component Salvador. NRS-RNAi and the NRS inhibitor tirandamycin B (TirB) suppressed Yorkie-mediated tumor phenotypes in Drosophila. Genetic analysis showed that NRS interacted with Salvador, and NRS activated Hippo target genes by regulating Yorkie phosphorylation. Biochemical analyses showed that NRS blocked Salvador-Hippo binding by interacting directly with Salvador, and TirB treatment inhibited NRS-Salvador binding. YAP target genes were upregulated in a mammalian cancer cell line with high expression of NRS, whereas TirB treatment suppressed cancer cell proliferation. These results indicate that NRS regulates tumor growth by interacting with Salvador in the Hippo signaling pathway.

Abstract
Many studies have indicated that Korean red ginseng (KRG) has anti-inflammatory and anti-oxidative effects, thereby inducing many health benefits in humans. Studies into the longevity effects of KRG are limited and have provided contradictory results, and the molecular mechanism of lifespan extension by KRG is not elucidated yet. Herein, the longevity effect of KRG was investigated in Drosophila melanogaster by feeding KRG extracts, and the molecular mechanism of lifespan extension was elucidated by using longevity-related mutant flies. KRG extended the lifespan of Drosophila when administrated at 10 and 25 μg/mL, and the longevity benefit of KRG was not due to reduced feeding, reproduction, and/or climbing ability in fruit flies, indicating that the longevity benefit of KRG is a direct effect of KRG, not of a secondary artifact. Diet supplementation with KRG increased the lifespan of flies on a full-fed diet but not of those on a restricted diet, and the longevity effect of KRG was diminished by the mutation of dSir2, a deacetylase known to mediate the benefits of dietary restriction. Similarly, the longevity effect of KRG was mediated by the reduction of insulin/IGF-1 signaling. In conclusion, KRG extends the lifespan of Drosophila through Sir2 and insulin/IGF-1 signaling and has potential as an anti-aging dietary-restriction mimetic and prolongevity supplement.

Abstract
The purpose of this study was to investigate doctors' and patients' perceptions of cervical intraepithelial neoplasia 1 (CIN 1) and its treatment methods. A survey questionnaire was offered to obstetrics and gynaecology doctors and patients with CIN 1 in 2017. Only 43% of patients knew of this disease. Regarding perceptions of its aetiology, 64% of the patients perceived human papillomavirus infection to be the main cause of CIN 1. Patients' most preferred treatments were medication (20%), followed by alternative treatment (14%). Among doctors, regular follow-up was the most preferred method for managing CIN 1. The survey showed that current treatment modalities for CIN 1 were satisfactory to only half of doctors (50%) and patients (53%). Overall, 70% of doctors responded that new drug development for CIN 1 is needed. Although, CIN 1 is a low-grade lesion, doctors and patients expressed the desire for new therapeutic agents to manage it.IMPACT STATEMENTWhat is already known on this subject? In general, treatment is not recommended for CIN 1 because lesions are considered indicative of transient HPV infection and spontaneously regress in most patients.What do the results of this study add? Regular follow-up for CIN 1 were satisfactory to only half of doctors and patients. Thirty-six percent of patients wanted active treatment instead of regular follow-up. In addition, 70% of doctors responded that new drug development for CIN 1 is needed.What are the implications of these findings for clinical practice and/or further research? Our results support the need for therapeutic agents for CIN 1.

Abstract
The aim of this study was to evaluate whether balneotherapy might be effective in patients with chronic pelvic pain (CPP) in the short term. This was an open and prospective pilot study. The balneotherapy programme was performed in a spa resort located in Wando Island, Republic of Korea from August 26 2018 to September 1 2018. It consisted of 10 heated seawater baths (38 °C, 20 minutes) and 10 mud-pack applications (40 °C, 10 minutes) for five days. Sixteen patients were enrolled. Upon analysing responses from a patient questionnaire, we found improvement in parameters such as pain, bladder irrigation symptoms and quality of life after balneotherapy. Inflammatory marker IL-1 and TNF-α was significantly decreased after treatment compared to baseline. There were no adverse events during treatment. Our data suggest that five-day balneotherapy can be beneficial for patients with CPP in the short term.Impact statementWhat is already known on this subject? The majority of articles in the field of balneotherapy discuss the treatment of rheumatic or dermatological disease. However, data on the effectiveness of balneotherapy for chronic pelvic pain are very limited.What the results of this study add? Our study suggests that balneotherapy can be beneficial for patients with CPP in the short-term. The duration of balneotherapy was five days, which is shorter than that of the European studies. Intuitively, it may be doubtful whether short-term therapy has any practical effect. As most people living in Korea have a vacation period of about one week each in summer and winter, the choice of a five-day programme in our study reflects the reality of vacation schedules.What the implications are of these findings for clinical practice and/or further research? Further studies are necessary to demonstrate the persistence of these benefits on the long term, as well as their existence in appropriate control group and different duration of treatment.

Abstract
Sirtuin is an essential factor that delays cellular senescence and extends the organismal lifespan through the regulation of diverse cellular processes. Suppression of cellular senescence by Sirtuin is mainly mediated through delaying the age-related telomere attrition, sustaining genome integrity and promotion of DNA damage repair. In addition, Sirtuin modulates the organismal lifespan by interacting with several lifespan regulating signaling pathways including insulin/IGF-1 signaling pathway, AMP-activated protein kinase, and forkhead box O. Although still controversial, it is suggested that the prolongevity effect of Sirtuin is dependent with the level of and with the tissue expression of Sirtuin. Since Sirtuin is also believed to mediate the prolongevity effect of calorie restriction, activators of Sirtuin have attracted the attention of researchers to develop therapeutics for age-related diseases. Resveratrol, a phytochemical rich in the skin of red grapes and wine, has been actively investigated to activate Sirtuin activity with consequent beneficial effects on aging. This article reviews the evidences and controversies regarding the roles of Sirtuin on cellular senescence and lifespan extension, and summarizes the activators of Sirtuin including Sirtuin-activating compounds and compounds that increase the cellular level of nicotinamide dinucleotide.

Abstract
OBJECTIVE We aimed to evaluate trends in the prevalence of human papillomavirus (HPV)-related diseases in the era before the introduction of organised HPV vaccination programmes in the Republic of Korea. METHODS This cross-sectional study used National Health Insurance Service data from 2002 to 2015 and included participants who were diagnosed with the following HPV-related diseases (codes from the International Classification of Diseases, 10th Revision): genital warts (A63.0); cancer in the head and neck (C00-C10), anus (C21), vulva (C51), vagina (C52), cervix uteri (C53) and penis (C60); carcinoma in situ (CIS) of the lip/oral cavity/pharynx (D00.0), anus (D01.3), cervix (D06), vulva (D07.1), vagina (D07.2) and penis (D07.4); benign neoplasms of the larynx (D14.1); and dysplasia of the cervix (N87), vagina (N89) and vulva (N90). For each diagnosis, the fraction of cases attributable to HPV in Korea was assessed based on the percentages of diseases attributable to HPV reported in some international studies. The age-standardised prevalence was estimated using the direct population-based method. RESULTS The overall age-standardised prevalence of HPV-related diseases increased from 2002 to 2015, mainly due to increased prevalence of genital warts in men and cervical dysplasia and CIS in women. In women, genital wart prevalence increased from 2002 (24.4 per 100 000) to 2011 (57.1) and then decreased until 2015 (53.5); in men, the prevalence increased steadily from 2002 (22.9) to 2015 (109.4). The prevalence of cervical dysplasia and CIS increased (from 86.5 in 2002 to 484.5 in 2015, and from 60.3 in 2002 to 114.9 in 2015, respectively), but that of cervical cancer decreased (from 120.0 in 2002 to 106.9 in 2015). CONCLUSIONS Non-organised HPV vaccination and organised cervical cancer screening may have contributed to the downward trend in genital wart prevalence and the upward trend in cervical abnormalities among women.

Abstract
A common feature of the aging process is a decline in immune system performance. Extensive research has sought to elucidate how changes in adaptive immunity contribute to aging and to provide evidence showing that changes in innate immunity have an important role in the overall decline of net immune function. Drosophila is an emerging model used to address questions related to immunosenescence via research that integrates its capacity for genetic dissection of aging with groundbreaking molecular biology related to innate immunity. Herein, we review information on the immunosenescence of Drosophila and suggest its possible mechanisms that involve changes in insulin/IGF(insulin-like growth factor)-1 signaling, hormones such as juvenile hormone and 20-hydroxyecdysone, and feedback system degeneration. Lastly, the emerging role of microbiota on the regulation of immunity and aging in Drosophila is discussed.

Abstract
Background The role of passive smoking on cervical carcinogenesis remains controversial. We investigated the association of passive smoking with the risk of cervical intraepithelial neoplasia (CIN) and cervical cancer. Methods The study recruited 1,322 women, aged 18–65 with normal cytology (n = 592), CIN1 (n = 420), CIN2/3 (n = 165), and cervical cancer (n = 145) from 2006 to 2009. This study is a cross-sectional analysis using the baseline data from the Korean human papillomavirus (HPV) cohort study. Detailed information on smoking behaviors and lifestyles were collected using questionnaires. Multinomial logistic regression analysis was performed to estimate multivariable-adjusted odds ratios (ORs). Results Passive smoking was not statistically related to the risk of CINs and cervical cancer. However, passive smoking among non-smokers was associated with higher CIN 1 risk (OR 1.53; 95% confidence interval [CI], 1.07–2.18), compared to not passive smoking, after adjusting for demographic factors, lifestyles, and oncogenic-HPV infection status. CIN 1 risk increased with longer time exposed to passive smoking (P for trend <0.0003). Multivariate odds of <2 hours/day of passive smoking and that of ≥2 hours/day of passive smoking were 2.48 (95% CI, 1.49–4.14) and 2.28 (95% CI, 1.21–4.26) for CIN 1, compared to not passive smoking. Conclusions This study found that passive smoking among non-smoking women is associated with the risk of CIN 1.

Abstract
We evaluated the survival ability of Staphylococcus aureus and the production of Staphylococcal enterotoxin A (SEA) in dried filefishes and julienned squid at 10°, 24°, and 35 °C for 5 months. S. aureus survived longer at 10 °C than 24° and 35 °C, and better in dried julienned squid than dried filefishes. At 35 °C, the populations of S. aureus were rapidly diminished and undetectable in dried filefishes and julienned squid after 14 and 19 days, respectively. SEA production did not increase during the 5-month storage period, regardless of the temperature and type of dried fish products. Although it is advised to store dried fish products at 10 °C for quality control in retail markets, refrigerated temperature is more likely to facilitate the survival of S. aureus in dried fish products. Thus, dried fish products should be produced and stored under hygienic conditions.

Abstract
To investigate the role of TWIST1 in tumor angiogenesis in epithelial ovarian cancer and to identify key molecules involved in angiogenesis. TWIST1 small interfering RNA was transfected into A2780 cells, while a complementary DNA vector was transfected into non-malignant human ovarian surface epithelial cells to generate a TWIST1-overexpressing cell line. To evaluate how this affects angiogenesis, human umbilical vein endothelial cell tube formation assays were performed using the control and transfected cell lines. An antibody-based cytokine array was used to identify the molecules involved in TWIST1-mediated angiogenesis. After knockdown of TWIST1 via transfection of TWIST1 small interfering RNA into A2780 cells, the number of tubes formed by human umbilical vein endothelial cells significantly decreased in a tube formation assay. In a cytokine array, TWIST1 downregulation did not significantly decrease the secretion of the common pro-angiogenic factor, vascular endothelial growth factor, but instead inhibited the expression of the CXC chemokine ligand 11, which was confirmed by both an enzyme-linked immunosorbent assay and western blotting. In contrast, TWIST1 overexpression resulted in increased secretion of CXC chemokine ligand 11. Conversely, CXC chemokine ligand 11 downregulation did not inhibit the expression of TWIST1. Furthermore, the ability of TWIST1-expressing A2780 cells to induce angiogenesis was found to be inhibited after CXC chemokine ligand 11 knockdown in a tube formation assay. TWIST1 plays an important role in angiogenesis in epithelial ovarian cancer and is mediated by a novel pro-angiogenic factor, CXC chemokine ligand 11. Downregulation of CXC chemokine ligand 11 can inhibit tumor angiogenesis, suggesting that anti-CXC chemokine ligand 11 therapy may offer an alternative treatment strategy for TWIST1-positive ovarian cancer.

Abstract
After human papillomavirus (HPV) vaccine guidelines published by Korean Society of Gynecologic Oncology (KSGO) in 2011, new studies have been published, leading to additional data regarding efficacy, safety, number of vaccination rounds, and ideal age of vaccine administration. We searched and reviewed the literatures focused on the efficacy of 2-dose schedule vaccination, the efficacy of 3-dose schedule vaccination in middle-aged women, the ideal age of 3-dose schedule vaccination, the safety of HPV preventive vaccine, and the ability of cross-protection of each HPV preventive vaccine. The KSGO has revised the previous guideline based on the results of the above studies.

Abstract
Diabetes is one of the most impactful diseases worldwide. The most commonly prescribed anti-diabetic drug is metformin. In this study, we identified an endosomal Na(+)/H(+) exchanger (NHE) as a new potential target of metformin from an unbiased screen in Caenorhabditis elegans The same NHE homolog also exists in flies, where it too mediates the effects of metformin. Our results suggest that endosomal NHEs could be a metformin target and provide an insight into a novel mechanism of action of metformin on regulating the endocytic cycle.

Abstract
Abstract
Poly-gamma-glutamic acid (γ-PGA) is known as viscous component of Korean chungkookjang and a natural polypeptide consisting of only glutamic acid with gamma-amide linkages. High molecular weight γ-PGA was isolated and mass-produced from Bacillus subtilisChungkookjang. Previously, accumulating evidences indicate that the γ-PGA inducesinnate immune response including natural killer (NK) cell activation and interferon secretion throughtoll-like receptor 4 (TLR4). To evaluate the immunotherapeutic effects, we’ve investigated the effect of γ-PGA on human NK cell activity and antiviral effect. First human study involving 99 healthy volunteers revealed thathigh-dosage γ-PGA group were significantly higher cytotoxic activities of NK cells than the low dosage and placebo groups at weeks 4 and 8 after the treatment. Furthermore, westudied the effect of γ-PGA on the treatment of vaginal intraepithelial neoplasia (VAIN). A retrospectiveobservational study on γ-PGA therapy for biopsy-proven VAIN suggest that γ-PGA may be helpful for the cytological regression and reduction of viral load in patients with high-risk HPV-positive VAIN. Since previous human studies showed the possibility of drug, we have accomplished a phase I dose escalation study to determine the safety, tolerance and pharmacokinetics of γ-PGA in healthy adult male subjects. The phase I study of oral γ-PGA was conducted in 20 healthy volunteers. There was no any significant difference in abnormal diagnoses or clinically relevant changes in laboratory parameters, vital signs, or other safety parameters. Currently, we have initiated a phase II trial to determine the efficacy and safety of γ-PGA compared with placebo in patients with cervical intraepithelial neoplasia grade 1 (CIN1). Total 200 patients with CIN1 will be administered with γ-PGA or placebo for 4 weeks followed by 8 weeks observation and compare the regression rate of CIN1.So far there was no serious adverse event (SAE) during phase II study. These results indicate that the oral administration of γ-PGAcan serve as treatment option that are safe and clinical efficacy via inducing NK cell activity and anti viral effect.

Abstract
This study investigates the in vivo functions of ginseng berry extract (GB) as a therapy for dextran sodium sulfate (DSS)-induced colitis. C57BL/6 mice were given drinking water containing DSS (3%) for eight days to induce acute colitis. At the same time, the mice received an oral dose of GB (50 mg/kg) once daily. The GB-treated mice were less susceptible to the development of acute colitis than were control mice treated with saline, as determined by weight loss, disease activity, and colon histology. The administration of GB to DSS-treated mice also reduced the numbers and inhibited the activation of colon-infiltrating T cells, neutrophils, intestinal CD103(-)CD11c⁺ dendritic cells (cDCs), and macrophages. In addition, GB treatment promoted the migration of CD103⁺CD11c⁺ cDCs and expansion of Foxp3⁺ regulatory T cells in the colons of DSS-treated mice. Similarly, in the DSS-induced chronic colitis model, GB treatment improved the macroscopic and histological appearance of the colon wall when compared to untreated control mice, as indicated by longer colon length and lower histological scores. This is the first report to show that oral administration of GB suppresses immune activation and protects against experimentally induced colitis.

Abstract
Phytoncides, which are volatile substances emitted from plants for protection against plant pathogens and insects, are known to have insecticidal, antimicrobial, and antifungal activities. In contrast to their negative effects on microorganisms and insects, phytoncides have been shown to have beneficial effects on human health. Essential oil from Hinoki cypress (Chamaecyparis obtusa) is mostly used in commercial products such as air purifiers. However, the physiological/behavioral impact of essential oil from C. obtusa on insects is not established. In this study, we tested the effects of essential oil extracted from C. obtusa on the physiologies and behaviors of Drosophila melanogaster and Musca domestica. Exposure to essential oil from C. obtusa decreased the lifespan, fecundity, locomotive activity, and developmental success rate of D. melanogaster. In addition, both fruit flies and house flies showed strong repellent behavioral responses to the essential oil, with duration times of about 5 hours at 70 μg/ml. These results suggest that essential oil from C. obtusa can be used as a ‘human-friendly’ alternative insect repellent.

Abstract
OBJECTIVE To determine the predictive factors for progression and recurrence of vulvovaginal condyloma (VVC), with a specific focus on high-risk HPV (HR-HPV) infections. METHODS Retrospective data were collected from 48 patients who were diagnosed with VVC and treated with topical trichloroacetic acid application or laser therapy during 2003-2014 at a hospital in South Korea. The diagnoses were made based on the presence of exophytic condylomatous lesions as assessed by direct visual inspection regardless of whether a biopsy was performed. RESULTS Overall, 18 patients (50.0% of those with a test result) were positive for HR-HPV. Three-quarters of the patients with a poor treatment response had abnormal cytologies, and abnormal cytology was a risk factor for a poor response (odds ratio, 4.33 [95% confidence interval, 1.05-17.84]). During a median follow-up of 24months, VVC recurred in seven (14.6%) patients. A high viral load (more than 50 relative light units) of HR-HPV was significantly associated with recurrence (odds ratio, 7.42, 95% confidence interval, 1.19-46.18). CONCLUSION A high HR-HPV load is a risk factor for recurrence, but is not related to treatment response. A poor treatment response is more related to abnormal cytology than it is to viral load.

Abstract
Abstract
Objectives: Although technologies continue to develop, there are still many limitations on detecting circulating tumor cells in blood. In addition, the great genetic heterogeneity in ovarian cancer is one of the major concerns. Therefore, we aimed to investigate the cell-free DNA (cfDNA) as a diagnostic marker for epithelial ovarian cancer (EOC) and evaluate the cfDNA level of epithelial-mesenchymal transition markers.
Methods: Blood was preoperatively collected from women who were assigned to surgery for pelvic mass. DNA was extracted using Qiagen DNA Mini kit and quantification of total cfDNA was performed using real-time PCR with TaqMan Assay with primers directed to the following genes:
GAPDH, β-globin, β-actin, E-cadherin, and fibronectin.
Results: A total of 32 patients with EOC and 17 patients of benign ovarian disease (controls) were included. The median cfDNA level of β-globin was 0 (range, 0-0.35)GE/ml in EOC and 0.41 (range, 0-33.5)GE/ml in control (p = 0.04).
The sensitivity of β-globin cfDNA (>0.4 GE/ml) was 51.9%, which was lower than that of CA-125 (96.3%, if CA-125 >35IU/ml). cfDNA was significantly higher in advanced stage of EOC than early stage EOC (p = 0.02). Plasma E-cadherin level was significantly related with β-globin cfDNA (coefficient 0.886, p<0.001). However, there was no significant association with cfDNA amount and survival outcomes.
Conclusions: Circulating cfDNA can be a promising target for early detection of EOC. The levels of epithelial-mesenchymal transition markers showed a different pattern in plasma and were associated with other cfDNA amounts.

Abstract
Ginseng extract has been shown to possess certain anti-virus, anti-tumor and immune-activating effects. However, the immunostimulatory effect of ginseng berry extract (GB) has been less well characterized. In this study, we investigated the effect of GB on the activation of mouse dendritic cells (DCs) in vitro and in vivo. GB treatment induced up-regulation of co-stimulatory molecules in bone marrow-derived DCs (BMDCs). Interestingly, GB induced a higher degree of co-stimulatory molecule up-regulation than ginseng root extract (GR) at the same concentrations. Moreover, in vivo administration of GB promoted up-regulation of CD86, MHC class I and MHC class II and production of IL-6, IL-12 and TNF-α in spleen DCs. GB also promoted the generation of Th1 and Tc1 cells. Furthermore, Toll like receptor 4 (TLR4) and myeloid differentiation primary response 88 (MyD88) signaling pathway were essential for DC activation induced by GB. In addition, GB strongly prompted the proliferation of ovalbumin (OVA)-specific CD4 and CD8 T cells. Finally, GB induced DC activation in tumor-bearing mice and the combination of OVA and GB treatment inhibited B16-OVA tumor cell growth in C57BL/6 mice. These results demonstrate that GB is a novel tumor therapeutic vaccine adjuvant by promoting DC and T cell activation.
