Abstract
INTRODUCTION AND HYPOTHESIS We aimed to clarify the frequency of cul-de-sac obliteration in patients undergoing POP surgery. METHODS We retrospectively reviewed patients who underwent laparoscopic POP surgery at our hospital between April 2017 and September 2021. RESULTS In total, 191 cases were included in the analysis. Ten patients (5.2%) had cul-de-sac obliteration. No difference in age (73 years vs. 72 years, P = 0.99), parity (2 vs. 2, P = 0.64), or body mass index (BMI) (25.7 kg/m2 vs. 24.7 kg/m2, P = 0.34) was observed between the cul-de-sac obliteration and normal groups. No significant differences were observed in the rate of previous abdominal surgery (50.0% vs. 32.6%, P = 0.46), rate of POP - quantification system (POP-Q) ≥ 2 posterior prolapse (40.0% vs. 46.4%, P = 0.98), and effect of defecation symptoms on the prolapse quality of life (p-QOL) score (vaginal bulge emptying bowels: 2.5 vs. 3.5, P = 0.15; empty bowel feeling: 3 vs. 3, P = 0.72, constipation: 3.5 vs. 3, P = 0.58; straining to open bowels: 3.5 vs. 3, P = 0.82; empty bowels with fingers: 1 vs. 1, P = 0.55) between the cul-de-sac obliteration and normal groups. Multivariate analysis of risk factors for the cul-de-sac obliteration was performed for age, number of births, previous abdominal surgery, and presence of rectocele; however no significant risk factors were extracted. CONCLUSION Predicting cul-de-sac obliteration preoperatively in patients undergoing POP surgery based on age, number of previous surgeries, previous abdominal surgeries, rectocele, and defecation symptoms is difficult.

Abstract
Objective This study was conducted to evaluate the status and role of cervical cytology affected by human papillomavirus infection and other infectious diseases screened during routine prenatal checkups. Methods We retrospectively examined medical records containing the screening results for infectious diseases and cervical cancer in women who delivered neonates in our hospital from 2014 to 2017. Results Among 3393 deliveries, 18.8% of women underwent a regular cervical cancer screening within 1 year of becoming pregnant, and 2641 women underwent a cervical cytology screening during this pregnancy. The cytological diagnostic results showed that 2562 women (97.0%) were negative for intraepithelial lesions or malignancy, whereas 79 (3.0%) had abnormal results. Of those with abnormal cytology results, 70 had abnormal cytology that was newly detected in this pregnancy, and 42 had grade ≥1 cervical intraepithelial neoplasia lesions. Spatulas were the most frequently used cytological sampling instruments, followed by cotton swabs. Cervical cytology revealed no major adverse reactions during these pregnancies. Conclusions Our results confirm the importance of screening for infectious diseases during pregnancy. Only 20% of the women underwent a regular pre-pregnancy cervical cytology screening. Cervical cytology screening during pregnancy may currently be playing a crucial role in preventing cervical cancer in Japan.

Abstract
The prevention of human error is an important task that has already been researched. Previous studies have shown that EEG signals can predict the occurrence of human errors. However, high accuracy has not yet been achieved in a single-trial analysis. This study is aimed to improve the accuracy of single-trial analysis, and propose a method for anomaly detection with auto encoder(AE). In the experiment, we conducted "Press the button(Go)" or "Do nothing(No-Go)" according to the visual stimulus and analyzed the EEG signal from -1000 ms to 0 ms when the stimulus was displayed. We prepared two types of inputs, time series data and frequency spectrum, and an AE was trained to reconstruct the inputs. We then calculated the difference between the reconstructed data and input data and predicted human error by its largeness. In the prediction using Support Vector Machine (SVM) based on the frequency spectrum, some over-fitting occurred and the average accuracy was 43 %. In the prediction using anomaly detection with frequency spectrum was 53 % and could not be classified. The time series data was 63 % which improved the accuracy. A previous study has shown frequency-dependent features such as -band activity and rhythm, as precursors of human error. However, in single-trial analysis, we obtained a higher accuracy by time series data than when by using the frequency spectrum. However, there was no noticeable difference between SVM and anomaly detection methods other than over-fitting. Therefore, in this case, the improvement in accuracy by the anomaly detection method could not be confirmed. However, the result suggests that it is more effective to use the frequency spectrum than the time series data in the single-trial analysis in the future.

Abstract
OBJECTIVE To examine the necessity and sufficiency of different types of hysterectomy for the surgical treatment of endometrial cancer. METHODS This was a multicenter collaborative study conducted by 11 institutions. Among patients with stage I-III endometrial cancer who underwent surgery as the initial treatment (only chemotherapy was provided if adjuvant therapy was needed) from 2001 to 2012, we retrospectively examined the type of hysterectomy, clinicopathological factors, recurrence rate over a maximum period of 5 years, and the site of recurrence. The local recurrence rate was examined by univariate and multivariate analyses. RESULTS Among 1335 patients, 982 (73.6%) underwent simple hysterectomy (SH) and 353 (26.4%) underwent modified radical hysterectomy (mRH) and were observed for a mean duration of 51.8 months. No significant difference was observed in the rate of local recurrence between the SH and mRH groups (p = 0.928). In multivariate analysis, clinicopathological factors independently associated with localized recurrence included postmenopausal status [hazard ratio (HR) 5.036, 95% confidence interval (CI) 1.506-16.841, p = 0.009], with stages II (HR 3.337, 95% CI 1.701-6.547, p < 0.001) and III (HR 2.445, 95% CI 1.280-4.668, p = 0.007), vs stage I and histological type 2 (HR 1.610, 95% CI 0.938-2.762, p = 0.001). CONCLUSIONS For endometrial cancer patients requiring surgery, the selection of a more extensive type of hysterectomy did not reduce the rate of local recurrence. Therefore, there is little significance in performing mRH in such cases.

Abstract
External fixators are an effective treatment option for comminuted or unstable phalangeal fractures. We developed a new linked-wire type of external fixator (the Ichi-Fixator) for finger phalangeal fractures, which enables fine adjustment of the fixation under fluoroscopy guidance either in a static way or with distraction through small screws inside the fixator. This technique was designed to improve on the stability and rigidity of conventional percutaneous Kirchner wire fixation. We assessed the effectiveness of the fixator through 12 cases of open or percutaneous fixation in comminuted or unstable phalangeal fractures. All patients were examined for postoperative complications, functional recovery, pain on visual analog scale (VAS), and the Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH) score at the final follow-up visit. Patients could perform all routine activities with normal grip strength and a full range of hand motion without pain after treatment. This treatment, which reduces the postoperative discomfort and may allow an immediate return to work, will clearly boost patient satisfaction. Linked-wire type external fixation enhances the security of fixation, facilitates postoperative mobilization, and may allow an immediate return to work.

Abstract
BACKGROUND We developed a novel plasma amino acid profile-based index (API) to detect ovarian, uterine, cervical, and endometrial cancers. In this study, we aimed to evaluate whether abnormal API values could be normalized after curative treatment in patients with gynecological malignant tumors. METHODS Patients with gynecological cancer with abnormal API values were included in this study. Pre-operative absolute API values were compared with those after curative treatment. The normalization rates of API values in patients negative for the expression of three well-known tumor markers (SCC, CA125, and CA19-9) were also evaluated. In addition, related amino acid profiles in healthy controls and patients under pre- and post-treatment conditions were analyzed. RESULTS Among 94 patients with abnormal pre-operative API values, the median API value was decreased from 9.52 to 2.17 after treatment (normalization rate: 88.3%). The decreased ranges were similar in patients with adenocarcinoma (6.28; 95% confidence interval [CI]: 5.43-6.95) and squamous carcinoma (7.44; 95% CI: 3.04-8.46). In 93.5% (43/46) of patients negative for tumor markers prior to operation, API values were normalized after the successful treatment. In addition, some pre-operative abnormal amino acid profiles, including Ile, Trp, and His, were reversibly normalized after treatment. CONCLUSION The API is a promising tumor marker in gynecological malignancies for the diagnosis of remission, particularly in patients negative for general tumor markers. Further studies are needed to explore the mechanisms related to the normalization of abnormal amino acid profiles.

Abstract
BACKGROUND Mycophenolate mofetil (MMF) and mizoribine (MZR) are increasingly used as immunosuppressive agents for organ transplantation and chronic inflammation. We report a patient with rheumatoid arthritis who had an acute inflammatory syndrome triggered by preoperative immunosuppression therapy with both MMF and MZR. CASE REPORT A 41-year-old woman with IgA nephropathy was referred to our department for living donor renal transplantation. She had rheumatoid arthritis that was adequately treated with prednisolone 5 mg once a day and salazosulfapyridine 2000 mg once a day. MMF 1000 mg twice a day was started for desensitization therapy. Three days later, the patient developed arthritis in the joints of her left hand and elevated inflammatory markers. On day 7, MMF was switched to MZR 150 mg 3 times a day. However, the symptoms extended to both shoulders and the joints of the right foot; MZR was discontinued. The arthritis and inflammatory markers improved. Two months later, the patient was rechallenged with MMF followed by MZR, resulting in a similar clinical course as previously. Tacrolimus (TAC) 3 mg twice a day and everolimus (EVL) 0.5 mg twice a day were introduced as alternative immunosuppressant therapies. No arthritis occurred. ABO-compatible living donor renal transplantation was successfully performed. The patient received TAC, EVL, prednisolone, rituximab, and basiliximab, and her postoperative course was uneventful without arthritis or rejection. At 9 months postoperatively, the serum creatinine was 0.79 mg/dL. CONCLUSIONS Acute inflammatory syndrome is an extremely rare complication triggered by preoperative immunosuppression therapy. If antimetabolites cannot be used in immunologically high-risk patients, transplantation becomes very difficult. Clinicians should keep in mind this paradoxical reaction.

Abstract
The focus of this work is the change in sediment properties and chemical characteristics that occur after land reclamation projects. The results indicate a higher sedimentation rate in Lake Hachirogata after reclamation, with the rate increasing with proximity to the agricultural zone. In the west-side water samples, higher levels of dissolved total nitrogen and dissolved total phosphorus (DTP) were found in both surface and bottom waters. The increase in P (39-80%) was generally greater than that for N (12-16%), regarding the nutrient supply from reclaimed farmland in the western part of the lake. In the eastern part of the lake, the pore-water Cl- profile showed a decreasing vertical gradient in the sediment core. This indicates desalination of the lake water after construction of a sluice gate in 1961. In the western sediment-core sample, a uniform Cl- profile indicates the mixing of lake water and pore water after reclamation. Considering the sedimentation of P in the last 100 years, there is a trend of increasing accumulation of P and P-activities after the reclamation project. This appears to be an impact from change in the lake environment as a result of increased agricultural nutrients, desalination, and residence. A large amount of mobile phosphorus (42-72% of TP in the western core sample) trapped in sediment increases the risk of phosphorus release and intensification of algal blooms. High sediment phosphorus and phosphorus mobility should be considered a source of pollution in the coastal environment.

Abstract
Effects of physical and morphometric factors on nutrient removal properties were studied in small agricultural ponds with different depths, volumes, and residence times in western Japan. Average residence time was estimated to be >15 days, and it tended to decrease from summer to winter because of the increase in water withdrawal for agricultural activity. Water temperature was clearly different between the surface and bottom layers; this indicates that thermal stratification occurred in summer. Chlorophyll-a was significantly high (>20 μg/L) in the surface layer (<0.5 m) and influenced by the thermal stratification. Removal ratios of dissolved total nitrogen (DTN) and dissolved total phosphorus in the ponds were estimated to be 53-98% and 39-98% in August and 10-92% and 36-57% in December, respectively. Residence time of the ponds was longer in August than in December, and DTN removal, in particular, was more significant in ponds with longer residence time. Our results suggest residence time is an important factor for nitrogen removal in small agricultural ponds as well as large lakes.

Abstract
Uterine superficial serous carcinoma (SSC) and serous endometrial intraepithelial carcinoma (SEIC) are unique malignancies found primarily in postmenopausal women. SSC and SEIC lesions measuring 1 cm or less are categorized as minimal uterine serous carcinoma (MUSC). Less well understood, however, the clinical behavior of SSC and SEIC lesions measuring more than 1 cm. We investigated 6 postmenopausal patients, aged 69-83 years, with SSC or SEIC and without hyperestrogenism. All but 1 patient had tumors originating from the surface of polyps, including 3 patients who each had an enormous polyp occupying the entire uterine cavity. Two patients had extensive SEICs measuring more than 1 cm; the others had SSCs, including 1 MUSC. The mesenchymal cells of the cancer-bearing polyps lacked the morphologic characteristics of endometrial stroma, and the cancer glands often immunostained negatively for estrogen receptors and progesterone receptors. Diffuse immunostaining for human epidermal growth factor receptor 2 was detected in 3 patients, and p53 was detected in all. Cyclin E, a downstream molecule of the F-box and WD repeat domain-containing 7 (FBXW7), was detected in all patients. Microdissected cancer glands showed p53 mutations in 2 patients and a FBXW7 mutation in 1 patient. These findings suggest that mutations of FBXW7 and p53 may contribute to the carcinogenesis of less invasive tumor subtypes. Pathologists and physicians should carefully evaluate SSC and SEIC lesions involving large polyps but lacking myometrial invasion.

Abstract
As the effects of supplementary oxygen on urinary excretion of 8-hydroxy-2'-deoxyguanosine (8-OHdG) are poorly understood, urinary 8-OHdG levels (ng/mg creatinine) were determined longitudinally on the postnatal day (PND) 1, 3, and 30 in 16 neonates with birth weight < 1000 g. No supplementary oxygen was required in 9 neonates during the first 24 h of life. Urinary 8-OHdG level on PND 1 was inversely correlated with birth weight in these 9 neonates (P = 0.0323) and was higher in four with birth weight < 750 g than five with birth weight > 750 g (41.0 ± 6.9 vs. 5.6 ± 2.7, respectively, P = 0.0200). Median urinary 8-OHdG on PND 1 of these 9 neonates was significantly lower than that of 7 neonates with oxygen (9.3 vs. 60.2, respectively), although there were no significant differences in clinical background, such as birth weight, between the two groups. Five of the 9 did not require supplemental oxygen at all during the first 30 days of life. Median urinary 8-OHdG levels were consistently significantly lower in the 5 neonates than in 11 neonates with oxygen transiently or persistently (9.3 vs. 54.6, 19.1 vs. 61.4, and 28.3 vs. 145 on PND 1, 3, and 30, respectively), although there were no differences in clinical background, such as birth weight, between the two groups. Urinary 8-OHdG on PND 30 was significantly positively correlated with supplemental oxygen dose on PND 30 (P < 0.0001), but not with birth weight in the 16 neonates. These results suggest that higher supplemental oxygen tension caused higher urinary 8-OHdG in this population.

Abstract
Abstract
The electronic structure of nitrogen atoms as impurities in an ionic TiO2 crystal has been investigated by analyzing electric field gradients (EFGs) measured by use of short-lived β-emitting 12N implant-ed following nuclear reactions. Conventional β-NMR and its modification, suitable for the detection of quadrupole effects in the NMR spectra, were used for the investigation of hyperfine interactions of 12N located in substitutional sites of O atoms and interstitial sites in the crystal. In order to deduce absolute values of the EFGs from the obtained eqQ/h, the quadrupole moment of 12N has been determined from the NMR detection of 12N implanted in BN(hexagonal) crystal. Here the EFG at the N atom in BN was measured by detecting the FT-NMR of 14N in the crystal. The EFGs in TiO2 are compared with the theoretical predictions based on the ab initio band-structure calculation in the framework of the KKR method.

Abstract
AIM This study investigated the status of cervical cancer screening among women in a university hospital-based community who received catch-up human papillomavirus (HPV) vaccinations as a basic element of our community-based cervical cancer prevention advocacy. METHODS Self-administered questionnaires were distributed to 173 women working or studying in the community at their first HPV vaccination in 2010, at the third vaccination, and 2 years later. Their demographics and attitudes toward the Pap test were analyzed. RESULTS The median age of the participants was 27.5 years and 88.2% were sexually active. Before the first vaccination, 38.5% (57/148) of the screening targets had never had a Pap test. Among the women who completed the third vaccination, Pap test experiences within the recent 2 years increased from 45.3% (63/139) at the first vaccination to 71.2% (99/137) at the third vaccination, and 67.5% (54/80) 2 years later. In 45.3% of the screening targets who had never had a Pap test at the time of their first HPV vaccination, their first Pap test was followed by their vaccination. CONCLUSIONS Having biennial Pap tests in accordance with the Japanese national cancer screening guideline was shown to be difficult even for the women in the medical community; however, education about the Pap test and the efficacy of HPV vaccination in providing opportunistic screening encouraged them to have their first or suspended Pap test. Our interim data suggest the need for urgently changing the cervical cancer prevention strategy for young adult women who are excluded from the national HPV vaccine program.

Abstract
Background: Narrowed true lumen and patent false lumen through to the terminal aorta is a high-risk condition for malperfusion syndromes (MS) in acute type-A aortic dissection. It is important to ascertain how the true and false lumens behave after surgery. Patients and Methods: We retrospectively investigated 45 patients with this pathology. The true lumen sizes at the narrowest levels above and below the superior mesenteric artery were followed by computed tomography after surgery (0-36 months). Results: Thirty-seven MS were seen in 23 patients. Hospital mortality was 8.9%. The narrowed true lumen was not enlarged in the first 6 months with a patent false lumen. The elephant trunk procedure did not improve the true lumen size. An extremely narrowed (≤3mm) true lumen was associated with a significantly high incidence of MS and mortality. Conclusions: High incidences of MS were observed in this particular pathology. An extremely narrowed true lumen was accompanied by a high incidence of MS and mortality.

Abstract
INTRODUCTION Social anxiety disorder is believed to be a stress-induced disease. Although it can be inferred from the symptoms during attacks that there exists some abnormality of autonomic nervous system in any of the stress systems in social anxiety disorder, little evidence has been reported. This study focused on comparing the reactivity of 2 stress systems, the autonomic nervous system (ANS) and the hypothalamic-pituitary-adrenal (HPA) axis in patients with social anxiety disorder. METHODS 32 patients with the generalized type of social anxiety disorder were compared with 80 age- and gender-matched controls. We collected saliva samples from patients and controls before and after electrical stimulation to measure the concentrations of salivary alpha-amylase (sAA) and salivary cortisol. Profile of Mood State (POMS) and State-Trait Anxiety Inventory (STAI) scores and Heart Rate Variability (HRV) were also determined following stimulation. RESULTS SAA in patients displayed a significantly higher level at baseline and a significantly larger response to electrical stimulation as compared to controls, whereas no group differences were seen in any HRV. Neither within-subject nor group differences were seen in salivary cortisol levels. CONCLUSIONS These results suggest that SAD patients displayed enhanced ANS (but not HPA axis) activity vs. healthy controls.

Abstract
We extended single molecule fluorescence imaging and time-resolved fluorometry from the green to the violet-excitation regime to find feasibility of detecting and identifying fluorescent analogs of nucleic-acid bases at the single-molecule level. Using violet excitation, we observed fluorescent spotsfrom single complexes composed of a nucleotide analogue and the Klenow fragmentof DNA polymerase I. Also, we implemented Raman imaging and spectroscopy of adenine molecules adsorbed on Ag colloidal nanoparticles to find feasibility of identifying nucleic-acid bases at the single-molecule level. Surface enhanced Raman scattering (SERS) of adenine molecules showed an intermittent on-and-off behavior called blinking. The observation of blinking provides substantial evidence for detecting single adenine molecules.

Abstract
Lymphocytes are of rich in delayed rectifier K(+)-channels (Kv1.3) in their plasma membranes, and the channels play crucial roles in the lymphocyte activation and proliferation. Since chloroquine, a widely used anti-malarial drug, exerts immunosuppressive effects, it will affect the channel currents in lymphocytes. In the present study, employing the standard patch-clamp whole-cell recording technique, we examined the effects of chloroquine on the channels expressed in murine thymocytes. Published papers report that chloroquine will inhibit voltage-dependent K(+)-channel currents by plugging into the open-pore. We observed, indeed, that chloroquine suppressed the pulse-end currents of Kv1.3-channels at higher voltage steps. Surprisingly, however, we found that the drug enhanced the peak currents at both higher and lower voltage steps. Since chloroquine showed such biphasic effects on the thymocyte K(+)-channels, and since those effects were voltage dependent, we examined the effects of chloroquine on the activation and the inactivation of the channel currents. We noted that chloroquine shifted both the activation and the inactivation curves toward the hyperpolarizing potential, and that those shifts were more emphasized at lower voltage steps. We conclude that chloroquine facilitates both the activation and the inactivation of Kv1.3-channel currents in thymocytes, and that those effects are voltage dependent.

Abstract
The ratio of the yields of antiprotons to protons in pp collisions has been measured by the ALICE experiment at sqrt[s]=0.9 and 7 TeV during the initial running periods of the Large Hadron Collider. The measurement covers the transverse momentum interval 0.45<p_{t}<1.05 GeV/c and rapidity |y|<0.5. The ratio is measured to be R_{|y|<0.5}=0.957±0.006(stat)±0.014(syst) at 0.9 TeV and R_{|y|<0.5}=0.991±0.005(stat)±0.014(syst) at 7 TeV and it is independent of both rapidity and transverse momentum. The results are consistent with the conventional model of baryon-number transport and set stringent limits on any additional contributions to baryon-number transfer over very large rapidity intervals in pp collisions.

Abstract
Abstract
Previous studies in this laboratory revealed that dihydrohonokiol-B (DHH-B; 3′-(2 propenyl)-5-propyl-(1,1′-biphenyl)-2,4′-diol), a partially reduced derivative of honokiol, was an effective anxiolytic-like agent in mice at an oral dose of 0.04 mg kg−1, and at higher doses, when evaluated by the elevated plus-maze test. The aim of this study was to further confirm the anxiolytic-like effect of DHH-B using an additional behavioural procedure (Vogel's conflict test in mice) and a biochemical assessment (in-vitro determination of muscimol-stimulated 36Cl− uptake into mouse cortical synaptoneurosomes). As in earlier experiments, DHH-B (0.04–1 mg kg−1, p.o.) was shown to prolong the time spent in the open-sided arms of the elevated plus-maze in a dose-dependent manner. Moreover, in the Vogel's conflict test, DHH-B (5 mg kg−1, p.o.) significantly increased punished water intake. In tests with mouse cerebral cortical synaptoneurosomes, 10 and 30 μm of DHH-B significantly increased 36Cl− influx in the absence of muscimol. In the presence of 25 μm muscimol, the addition of 1 μm DHH-B led to significant enhancement of 36Cl− uptake, while 30 μm DHH-B was required to further stimulate the 36Cl− uptake induced by 250 μm muscimol. The results of these studies confirm that DHH-B is a potent anxiolytic-like agent and that GABAA receptor-gated Cl−-channel complex is involved in the anxiolytic-like efficacy of DHH-B.

Abstract
OBJECTIVE Congenital diaphragmatic hernia (CDH) has a poor prognosis, despite intensive management. The prognosis of CDH is correlated with hypoplastic lung, but it is difficult to measure the degree of hypoplasia. The aims of this study were, therefore, to examine the relationship between chest X-ray and prognosis, and to assess whether the radiographic findings were a good indicator of hypoplastic lungs in patients with CDH. STUDY DESIGN Fifty neonates with CDH were classified radiographically into apex and hilar types. To assess the differences in clinical course between these two groups, gestational age, birth weight, prenatal diagnosis, survival rate, requirement of extracorporeal membrane oxygenation (ECMO) therapy and lung area on X-rays were analyzed. RESULTS In all, 32 cases were of the apex type and 18 were hilar. The survival rate of the hilar group (33%) was significantly worse than that of the apex group (81%) (P<0.001). The hilar group required ECMO therapy more frequently than did the apex group. CONCLUSIONS The present results show a significant correlation between survival rate and the findings of chest X-rays in CDH. Radiographic findings are thus a good clinical indicator of the prognosis of CDH in neonates.
