Domain Wall Junction in N=2 Supersymmetric QED in four dimensions

An exact solution of domain wall junction is obtained in N=2 supersymmetric (SUSY) QED with three massive hypermultiplets. The junction preserves two out of eight SUSY. Both a (magnetic) Fayet-Iliopoulos (FI) term and complex masses for hypermultiplets are needed to obtain the junction solution. There are zero modes corresponding to spontaneously broken translation, SUSY, and U(1). All broken and unbroken SUSY charges are explicitly worked out in the Wess-Zumino gauge in N=1 superfields as well as in components. The relation to models in five dimensions is also clarified.Comment: 27 pages, 6 figures, comments on zero modes added, a few references adde

Novel adsorptive type apheresis device Immunopure for ulcerative colitis from clinical perspectives based on clinical trials : Japan and Europe.

Several adsorptive type devices for ulcerative colitis are used for the induction of remission in patients with active severe disease worldwide. In 2020, the novel apheresis device Immunopure for ulcerative colitis was launched in Japan. Immunopure, like the polyethylene terephthalate column, uses polyarylate, a type of polyester resin, as the adsorbent. Similar to the cellulose acetate column, Immunopure is filled with adsorbent beads and expected to provide ease of use, with minimal risk of column clogging. Immunopure adsorbs leukocytes and platelets, especially activated platelets and platelet-leukocyte aggregates. In this article, the capability of Immunopure is evaluated from clinical perspective based on a clinical trial in Japan/Europe. As a result, Immunopure is comparable to other products in clinical effectiveness and indicated for the treatment of patients with refractory moderate ulcerative colitis, making it highly useful in clinical practice

A nationwide, multi-center, retrospective study of symptomatic small bowel stricture in patients with Crohn\u27s disease.

BACKGROUND:Small bowel stricture is one of the most common complications in patients with Crohn\u27s disease (CD). Endoscopic balloon dilatation (EBD) is a minimally invasive treatment intended to avoid surgery; however, whether EBD prevents subsequent surgery remains unclear. We aimed to reveal the factors contributing to surgery in patients with small bowel stricture and the factors associated with subsequent surgery after initial EBD.METHODS:Data were retrospectively collected from surgically untreated CD patients who developed symptomatic small bowel stricture after 2008 when the use of balloon-assisted enteroscopy and maintenance therapy with anti-tumor necrosis factor (TNF) became available.RESULTS:A total of 305 cases from 32 tertiary referral centers were enrolled. Cumulative surgery-free survival was 74.0% at 1 year, 54.4% at 5 years, and 44.3% at 10 years. The factors associated with avoiding surgery were non-stricturing, non-penetrating disease at onset, mild severity of symptoms, successful EBD, stricture length < 2 cm, and immunomodulator or anti-TNF added after onset of obstructive symptoms. In 95 cases with successful initial EBD, longer EBD interval was associated with lower risk of surgery. Receiver operating characteristic analysis revealed that an EBD interval of ≤ 446 days predicted subsequent surgery, and the proportion of smokers was significantly high in patients who required frequent dilatation.CONCLUSIONS:In CD patients with symptomatic small bowel stricture, addition of immunomodulator or anti-TNF and smoking cessation may improve the outcome of symptomatic small bowel stricture, by avoiding frequent EBD and subsequent surgery after initial EBD

Increased Glycine-conjugated and Unconjugated Bile Acid Levels Associated with Aggravation of Nonalcoholic Steatohepatitis and Cardiovascular Disease in SHRSP5/Dmcr Rat

The SHRSP5/Dmcr is a useful animal model for the development of nonalcoholic steatohepatitis (NASH) pathology when fed a high-fat, high-cholesterol diet, and further drug interventions can lead to concomitant cardiovascular disease. While SHRSP5/Dmcr rats have been used for basic research related to NASH, details of their bile acid metabolism in this condition are unknown. In this study, we aimed to clarify the changes in the serum bile acid (BA) fractions associated with NASH and found that glycine-conjugated and unconjugated bile acid increased with worsening NASH and cardiovascular disease while taurine-conjugated BA relatively decreased

Circumstances and factors of sleep-related sudden infancy deaths in Japan.

BackgroundSudden unexpected death in infancy (SUDI) comprises both natural and unnatural causes of death. However, few epidemiological surveys have investigated SUDI in Japan.ObjectiveThis retrospective study was conducted to investigate the latest trends of circumstances and risk factors of SUDI cases in which collapse occurred during sleep.MethodsForensic pathology sections from eight universities participated in the selection of subjects from 2013 to 2018. Data obtained from the checklist form were analyzed based on information at postmortem.ResultsThere were 259 SUDI cases consisting of 145 male infants and 114 female infants with a mean birth weight of 2888 ± 553 and 2750 ± 370 g, respectively. Deaths most frequently occurred among infants at 1 month of age (18%). According to population data as the control, the odds ratio (95% confidence interval) of mother's age ≤19 years was 11.1 (6.9-17.7) compared with ages 30-39. The odds ratio for the fourth- and later born infants was 5.2 (3.4-7.9) compared with the frequency of first-born infants. The most frequent time of day for discovery was between 7 and 8 o'clock, and the time difference from the last seen alive was a mean of 4.1 h. Co-sleeping was recorded for 61%, and the prone position was found for 40% of cases at discovery. Mother's smoking habit exhibited an odds ratio of 4.5 (2.9-5.8).ConclusionThis study confirmed the trends that have been observed for sudden infant death syndrome; particularly, very high odds ratios were evident for teenage mothers and later birth order in comparison with those in other developed countries. Neglect was suspected in some cases of the prolonged time to discovery of unreactive infants. To our knowledge, this is the first report of an extensive survey of SUDI during sleep in Japan
