Members of the brackish-water species Lamprothamnium succinctum (Charales, Charophyceae) arewidely distributed from tropical to temperate regions, including East Asia. In Japan, L. succinctum is listedas an endangered species and is protected by the government, because it was recorded only at two localities,Lake Hachiro-gata (Akita Prefecture) and Oo-ike pond (Deba-jima Island, Tokushima prefecture),and has become extinct in the former. In this study, we identified five new localities of this species inJapan. The morphological characteristics of their thalli agreed with those provided in the originaldescription of this species, with distinctive reproductive characteristics. Moreover, the oospores of Japanesespecimens of L. succinctum were examined for the first time using scanning electron microscopy. The oospores of Japanese specimens exhibited granulate fossa wall patterns, which were consistent withthose described in previous studies. Our genetic analyses based on the DNA sequences of two chloroplastDNA markers, including both the coding and non-coding regions, revealed that the sample from Oo-ikepond is distinguishable from those from other Japanese specimens, although they are genetically verysimilar.

Background/Aims Few studies are available that have investigated the risk factors for overlapping irritable bowel syndrome (IBS)-like symptoms in patients with inactive inflammatory bowel disease (IBD). The present study has 3 objectives: (1) to assess the prevalence of IBS-like symptoms in Japanese patients with inactive IBD using Rome III criteria, (2) to examine the relationship of IBS-like symptoms to health related quality of life (HR-QOL), and (3) to investigate associations for developing IBS-like symptoms in patients with inactive IBD. Methods IBS-like symptoms were evaluated using the Rome III questionnaire for functional gastrointestinal disorders. HR-QOL and hospital anxiety and depression scale were evaluated. Results IBS-like symptoms were found in 17.5% (7/40) of patients with inactive ulcerative colitis, 27.1% (29/107) of patients with inactive Crohn’s disease (CD), and 5.3% (23/438) of healthy control subjects. The QOL level was significantly lower and anxiety score was significantly higher in inactive CD patients with IBS-like symptoms than in those without such symptoms (P = 0.003, P = 0.009). Use of anti-anxiety drugs was associated with the presence of IBS symptoms (P = 0.045). HR-QOL score was lower and anxiety score was higher in patients with inactive ulcerative colitis, but the difference was not statistically significant. Conclusions The prevalence of IBS-like symptoms in inactive IBD patients was significantly higher than in healthy controls. Inactive CD patients with IBS-like symptoms has low QOL and anxiety; suggesting that anxiety may be associated with symptom development in such patients.

Purpose Despite widespread adoption of open abdominal management (OAM), there is currently no threshold criterion for OAM duration for non-trauma patients. Moreover, there is a positive relationship between morbidity and the duration of OAM, but an uncertain relationship with patients’ age. Therefore, a novel clinical index for the duration of open abdominal management (IDOM) was developed based on the patient’s age and risk of severe complications following OAM to indicate the maximum tolerable number of days of OAM based on the individual’s age. The utility of this new index was evaluated. Methods This retrospective study included 65 non-trauma patients managed with an open abdomen (OA) from August 2015 to August 2018. The IDOM was developed based on the patient’s age. The result indicated the maximum number of OA days. Patients’ demographic and operative variables were examined and patient data was assigned to one of two groups according to whether the actual number of OA days was above or below the calculated IDOM. Prevalence of complications between these groups was compared. Measures of validity were employed to assess the utility of the IDOM for patient complications. Results Sixty-five patients were included. The above-the calculated IDOM group exhibited a significantly longer OA and higher rates of wound complications and postoperative respiratory complications compared with the below the calculated IDOM group. The IDOM predicted the incidence of OA-related complications with a sensitivity of 72.4%, and a specificity of 80.6%. Conclusion The IDOM is a potentially useful tool for appropriate duration at the outset of OA.

[Purpose] Moderate-intensity exercise is known to be the best effective intensity to enhance cognitive function, including memory and learning. However, the effects of high-intensity exercise in comparison with moderate- intensity exercise on cognitive function remain controversial. The aim of this study was to investigate the effect of high-intensity resistance exercise on cognitive function. [Methods] Thirty-six healthy female college students volunteered to participate in this study. The participants were divided into four groups: (i) control group (CON); (ii) high-intensity resistance exercise group (HIR); (iii) high-intensity aerobic exercise group (HIA); and (iv) combined moderate-intensity exercise group (MIC). Immediately prior to and after exercise, the solved number (SN) and reaction times (RT) in the Stroop test (neutral task, NT and incongruent task, IT), as well as the tissue oxygen index (TOI) in the left and right prefrontal cortex (PFC) were measured in all groups. [Results] In the NT, both HIR and MIC groups showed significant improvements in SN and RT compared with the CON group. Meanwhile, performance in the HIA group was significantly attenuated compared with that in the MIC group. In the IT, only the MIC group showed a significant increase in SN and RT compared with the CON group. Furthermore, the TOI in the PFC (left PFC in the NT, and bilaterally in the IT) was significantly lower in the HIR group compared with that in the CON group. [Conclusion] The results of this study show worse cognitive performance and decreased PFC oxygenation in high-intensity exercise compared with moderate-intensity exercise and controls. These results suggest that high-intensity exercise may not improve cognition as effectively as moderate-intensity exercise.

Background: Two randomized phase III trials (EORTC55971 and CHORUS) showed similarprogression-free and overall survival in primary or interval debulking surgery in ovariancancer, however both studies had limitations with lower rate of complete resection and lack ofsurgical qualifications for participating centers. There is no consensus on whether neoadjuvantchemotherapy followed by interval debulking surgery (NACT-IDS) could be a preferred approachin the management of advanced epithelial ovarian cancer (EOC) in the clinical practice. Methods: The Asian SUNNY study is an open-label, multicenter, randomized controlled,phase III trial to compare the effect of primary debulking surgery (PDS) to NACT-IDS instages IIIC and IV EOC, fallopian tube cancer (FTC) or primary peritoneal carcinoma (PPC). The hypothesis is that PDS enhances the survivorship when compared with NACT-IDS inadvanced ovarian cancer. The primary objective is to clarify the role of PDS and NACT-IDS inthe treatment of advanced ovarian cancer. Surgical quality assures include at least 50% of nogross residual (NGR) in PDS group in all centers and participating centers should be nationalcancer centers or designed ovarian cancer section or those with the experience participatingsurgical trials of ovarian cancer. Any participating center should be monitored evaluatingthe proportions of NGR by a training set. The aim of the surgery in both arms is maximalcytoreduction. Tumor burden of the disease is evaluated by diagnostic laparoscopy orpositron emission tomography/computed tomography scan. Patients assigned to PDS groupwill undergo upfront maximal cytoreductive surgery within 3 weeks after biopsy, followed by6 cycles of standard adjuvant chemotherapy. Patients assigned to NACT group will undergo 3cycles of NACT-IDS, and subsequently 3 cycles of adjuvant chemotherapy. The maximal timeinterval between IDS and the initiation of adjuvant chemotherapy is 8 weeks. Major inclusioncriteria are pathologic confirmed stage IIIC and IV EOC, FTC or PPC; ECOG performancestatus of 0 to 2; ASA score of 1 to 2. Major exclusion criteria are non-epithelial tumors as wellas borderline tumors; low-grade carcinoma; mucinous ovarian cancer. The sample size is 456subjects. Primary endpoint is overall survival.

The purpose of this study was to examine the effect of cognitive function on a combined aerobic dance and high intensity music. The 28 subjects (female college students) were recruited and were divided into 4 groups; the Control Group (CG, n=7), Music Group (MG, n=7), Aerobic dance Group (AG, n=7) and Music and Aerobic dance Group (MnAG, n=7). AG and MnAG participated in aerobic dance exercise for 10 minutes. MG and MnAG listened to high intensity music (100Db) and CG and AG received no music intervention. For the delivery of music intervention, a headset was used. All subjects were measured on Stroop score, which is known as Neutral and Incongruent test as a cognitive function before and after 10 min-treatment. Data were analyzed by using two-way repeated ANOVA and one-way ANOVA. The results were as follows: An interaction effect between groups on Neutral and Incongruent test were observed (p<.0l, p<.05, respectively). The change ratios of pre-post Stroop score were significantly decreased both in Neutral and Incongruent test in only MnAG compared with CG (p<.05, 0.05, respectively). Therefore, the results showed that performing aerobic dance with high intensity music appeared to cause temporary decrease in cognitive function.
