Background/Aims: We retrospectively analyzed Crohn’s disease (CD) patients with small intestinal strictures who underwent single-balloon enteroscopy (SBE) to ascertain whether prototype SBEs with a passive bending mechanism and high force transmission insertion tube had better insertability in the small intestine than a conventional SBE. Methods: Among 253 CD patients who underwent SBE, we identified 94 CD patients who had undergone attempted endoscopic balloon dilatation (EBD) for small intestinal stenosis for inclusion in this study. We analyzed whether the type of scope used for their initial procedure affected the cumulative surgery-free rate. For the insertability analysis, patients who underwent SBE at least twice were divided into 3 groups according to the type of scope used: conventional SBE only, prototype SBE only, and both conventional and prototype SBEs. For each group, depth of insertion, procedure time, and number of EBDs were compared in the same patient at different time points. Results: The success rate of EBD was 88.3%. The 5- and 10-year cumulative surgery-free rate was 75.7% and 72.8%, respectively. Cox regression analysis indicated that the factors contributing to surgery were long stricture (≥2 cm), EBD failure, and elevated Crohn’s Disease Activity Index, but not the type of scope used for EBD. The prototype SBEs significantly improved the depth of insertion (P=0.03, Wilcoxon’s signed-rank test). Conclusions: In CD patients with small intestinal stenosis, the prototype SBEs with a passive bending mechanism and high force transmission insertion tube did not improve long-term EBD outcome but did improve deep insertability.

We investigated the effect of various concentrations of taurine during in vitro fertilization (IVF) on the embryonic development up to the blastocyst stage of bovine oocytes fertilized with three different Japanese Black bulls (Bull A, B and C). In vitro matured oocytes were fertilized with various concentrations of taurine (0, 1, 10, 50 and 100 mM) in the presence of 2.5 or 5.0 mM caffeine plus $25{\mu}g$/ml heparin (CH) for 6 hr or $100{\mu}g$/ml heparin (H) for $24{\pm}2$ h. After IVF, the cleavage rates from the 2 to 16 cell stage determined at 3 days and the development rates up to the blastocyst stage determined at 7-8 days from the onset of IVF were assessed. Although the cleavage rates for the taurine concentration groups were not significantly increased in any of the three bulls in the CH groups, the development rates up to the blastocyst stage of the 50 mM taurine group of Bulls A and B, and of the 1 to 50 mM groups of Bull C were increased (p<0.05) compared to those of the control (0 mM taurine) groups. On the other hand, none of the bulls in the H groups showed any significant increase either in the cleavage rates or blastocyst formation rates in any taurine concentrations groups compared with those of the control groups. These results indicate that the addition of 50 mM taurine to a fertilization medium containing caffeine and heparin may stimulate embryonic development up to the blastocyst stage when fertilized with different bull semen.

Objective: The present study aimed to survey seasonal changes in reproductive performance of local cows receiving artificial insemination (AI) in the Pursat province of Cambodia, a tropical country, to investigate if ambient conditions affect the reproductive performance of cows as to better understand the major problems regarding cattle production. Methods: The number of cows receiving AI, resultant number of calving, and calving rate were analyzed for those receiving the first AI from 2016 to 2017. The year was divided into three seasons: cool/dry (from November to February), hot/dry (from March to June), and wet (from July to October), based on the maximal temperature and rainfall in Pursat, to analyze the relationship between ambient conditions and the reproductive performance of cows. Body condition scores (BCS) and feeding schemes were also analyzed in these seasons. Results: The number of cows receiving AI was significantly higher in the cool/dry season than the wet season. The number of calving and calving rate were significantly higher in cows receiving AI in the cool/dry season compared with the hot/dry and wet seasons. The cows showed higher BCSs in the cool/dry season compared to the hot/dry and wet seasons probably due to the seasonal changes in the feeding schemes: these cows grazed on wild grasses in the cool/dry season but fed with a limited amount of grasses and straw in the hot/dry and wet seasons. Conclusion: The present study suggests that the low number of cows receiving AI, low number of calving, and low calving rate could be mainly due to poor body condition as a result of the poor feeding schemes during the hot/dry and wet seasons. The improvement of body condition by the refinement of feeding schemes may contribute to an increase in the reproductive performance in cows during the hot/dry and wet seasons in Cambodia.

Udagawa, Tsuyoshi,Yasuhiro, Hayashi,Takahashi, Naoyuki,Matsuura, Yasuo,Morita, Tomohiko,Minami, Masahiro The Korean Institute of Electrical Engineers 2013 The Journal of International Council on Electrical Vol.3 No.2

Measured data from IT switches are utilized in order to control voltage in Japanese distribution systems with photovoltaic generation systems. However, length of period from the data measurement to the data acquisition from IT switches by SCADA affects voltage control ability in a distribution automation system. In this paper, the effect of the length of the data acquisition period for voltage control by LRT and SVR is evaluated through numerical simulations in a distribution system model. Furthermore, the optimal length of the data acquisition period is determined according to PV penetration rate.

Nutritional condition in the dry period is related to the incidence of postpartum subclinical endometritis in dairy cattle

Taniguchi Asako,Nishikawa Tatsuya,Morita Yasuhiro 아세아·태평양축산학회 2021 Animal Bioscience Vol.34 No.4

Objective: Endometritis is a major disease, that causes infertility in cattle, and is usually categorized as clinical or subclinical endometritis (SCE). The nutritional condition during the dry period is important for recovery after the last stage of the lactation period, and for postpartum production and reproduction. This study aimed to clarify the relationship between nutritional and metabolic characteristics in the dry period, and the risk of postpartum SCE. Methods: Multiparous Holstein dairy cows (n = 25, raised in a tied stall) were used. Endometrial cytological analysis was performed around 30 days post-partum, with 5% to 14% polymorphonuclear (PMN) as a cut-off point to define SCE. Serum levels of glucose, non-esterified fatty acids, β-hydroxybutyric acid (BHBA), blood urea nitrogen, total cholesterol, aspartate aminotransferase, γ-glutamyl transpeptidase, calcium, phosphorus, and magnesium were measured in the cows at the dry period to evaluate energy status, protein metabolism, and mineral metabolism. Results: The incidence of SCE in the cows was 60.0% (n = 15/25) and the mean PMN% in postpartum cows diagnosed as SCE was 8.05%±2.6%. Overall, 17 and 8 samples were collected from the cows in the far-off and close-up periods, respectively. The serum concentration of BHBA in the far-off period and serum glucose concentration in the closeup period were correlated with postpartum PMN% (r = 0.62, p<0.01; r = –0.74, p<0.05, respectively). Serum levels of calcium and magnesium in the dry period were associated with the incidence of postpartum SCE (healthy vs SCE cows, p<0.05). Conclusion: Blood levels of glucose, BHBA, calcium, and magnesium in dry periods could be useful parameters for predicting the risk of postpartum SCE. The present study also suggests that management in the close-up period is essential for promoting recovery from calving fatigue.

Akinori Ichinose,Yuji Ishibashi,Fumihiko Hatao,Yasuhiro Morita 대한외과학회 2023 Annals of Surgical Treatment and Research(ASRT) Vol.104 No.4

Purpose: The present study aimed to examine the characteristics, outcomes, and problems related to surgery for acute abdomen in adult patients with severe motor and intellectual disabilities (MID). Methods: The clinical records of 35 adult patients with severe MID who received emergency surgery for acute abdomen between 2011 and 2020 were reviewed. Results: The median duration from onset to surgery was 48 hours. There were 2 cases of in-hospital mortality (5.7%), and all the patients underwent surgery more than 72 hours after onset. The in-hospital mortality rate was significantly higher in patients who received surgery later than 72 hours after onset. Bowel obstruction was the most common disease among the acute abdomen cases (71.4%) and most often involved volvulus of the small bowel and cecum. Of the patients with bowel obstruction with severe MID, 72.0% had abdominal distention, 16.0% had abdominal pain, and 4.0% had vomiting. The median duration from onset to surgery was significantly longer in the patients with bowel obstruction with severe MID than in those without severe MID (24 hours vs . 16 hours). Conclusion: Acute abdomen in patients with severe MID was often due to bowel obstruction caused by volvulus. Because patients with severe MID have few symptoms, they are susceptible to adverse surgical outcomes associated with a prolonged duration from onset to surgery.

Sarcopenia and lower limb pain are additively related to motor function and a history of falls and fracture in community-dwelling elderly people

Kohei Maruya,Hiroaki Fujita,Tomoyuki Arai,Ryoma Asahi,Yasuhiro Morita,Hideaki Ishibashi 대한골다공증학회 2019 Osteoporosis and Sarcopenia Vol.5 No.1

Objectives: To clarify the prevalence and characteristics of pain associated with sarcopenia and to verify the usefulness of evaluation of pain for sarcopenia. Methods: In total, 759 community-dwelling people (aged 65e79 years) with or without sarcopenia and lower limb pain were classified into 4 groups (NSp, nonsarcopenia; NSpP, nonsarcopenia with pain; Sp, sarcopenia; and SpP, sarcopenia with pain). Body composition, motor function, history of fractures since age 50 years, and number of falls in the past 1 year were compared between the groups. Results: Participant proportions by group were: NSp, 53.9%; NSpP, 42.8%; Sp, 1.3%; and SpP, 2.0%. Participants with lower limb pain showed low single leg standing, walking speed, and 2-step value scores and high 25-question Geriatric Locomotive Functional Scale (GLFS-25) score after adjusting for age, sex, body mass index, and presence of sarcopenia. The SpP group showed lower functional reach test and higher GLFS-25 scores than the Sp group. Regarding the history of fractures since 50 years of age and falls in past 1 year, a high retention rate of fracture was noted in the NSpP group. They also experienced significantly more falls in the past 1 year than those in the NSp group. The SpP group noted more falls and fractures although it was insignificant. Conclusions: The results indicate that participants with lower limb pain showed declining motor function and a high risk for falls and fractures. Sarcopenia could escalate this risk. Therefore, evaluating patients for both pain and sarcopenia may be useful for risk assessment and treatment.
