Time Variability of Nonthermal X-ray Stripes in Tycho's Supernova Remnant with Chandra

Analyzing Chandra data of Tycho's supernova remnant (SNR) taken in 2000, 2003, 2007, 2009, and 2015, we search for time variable features of synchrotron X-rays in the southwestern part of the SNR, where stripe structures of hard X-ray emission were previous found. By comparing X-ray images obtained at each epoch, we discover a knot-like structure in the northernmost part of the stripe region became brighter particularly in 2015. We also find a bright filamentary structure gradually became fainter and narrower as it moved outward. Our spectral analysis reveal that not only the nonthermal X-ray flux but also the photon indices of the knot-like structure change from year to year. During the period from 2000 to 2015, the small knot shows brightening of $\sim 70\%$ and hardening of $\Delta \Gamma \sim 0.45$. The time variability can be explained if the magnetic field is amplified to $\sim 100~\mathrm{\mu G}$ and/or if magnetic turbulence significantly changes with time.Comment: 8 pages, 3 figures, 2 tables, accepted for publication in Ap

Breadand Effervescent Beverage Productions with Local Microbes for the Local Revitalization

Local microbes such as yeasts fungi and bacilli, were isolated and used to apply for the food processing (bread making) and the production of an effervescent beverage (fruits kvass) for promotion of the local revitalization. Our yeast isolates could contribute to make the breads that can sell in alocal bakery shop.  Furthermore, the same yeasts could be used for making the fruit kvass (a Russian effervescent beverage which was fermented by yeast) with local fruit products (lemon, dry grape, mandarin orange and apple that were produced in Hiroshima prefecture in Japan). Development of merchandise having the local brand, which was made with only products of Hiroshima prefecture was attempted. Results of these activities demonstrate that the search of local microbes can help to establish the regional brand product related to its local area. They also showed that the local microbes have the potential ability to lead the local revitalization and the local brand product

A Case Report of Tooth Wear Associated with a Patient's Inappropriate Efforts to Reduce Oral Malodor Caused by Endodontic Lesion

Here, we report a case of severe tooth wear associated with a patient's inappropriate efforts to reduce oral malodor. A 72-year-old male patient visited our breath clinic complaining of strong breath odor. Former dentists had performed periodontal treatments including scaling and root planing, but his oral malodor did not decrease. His own subsequent breath odor-reducing efforts included daily use of lemons and vinegar to reduce or mask the odor, eating and chewing hard foods to clean his teeth, and extensive tooth brushing with a hard-bristled toothbrush. Oral malodor was detected in our breath clinic by several tests, including an organoleptic test, portable sulphide monitor, and gas chromatography. Although patient's oral hygiene and periodontal condition were not poor on presentation, his teeth showed heavy wear and hypersensitiving with an unfitted restoration on tooth 16. Radiographic examination of the tooth did not reveal endodontic lesion, but when the metal crown was removed, severe pus discharge and strong malodor were observed. When this was treated, his breath odor was improved. After dental treatment and oral hygiene instruction, no further tooth wear was observed; he was not concerned about breath odor thereafter

高非抱合型ビリルビン血症に対する光療法における青色と緑色光を混合した光療法は青色光単色と治療効果は同等であり、かつ光酸化ストレス反応を軽減する : Gunn ratモデルにおける検討

OBJECTIVE:Phototherapy using blue light-emitting diodes (LED) is effective against neonatal jaundice. However, green light phototherapy also reduces unconjugated jaundice. We aimed to determine whether mixed blue and green light can relieve jaundice with minimal oxidative stress as effectively as either blue or green light alone in a rat model. METHODS:Gunn rats were exposed to phototherapy with blue (420-520 nm), filtered blue (FB; 440-520 nm without<440-nm wavelengths, FB50 (half the irradiance of filtered blue), mixed (filtered 50% blue and 50% green), and green (490-590 nm) LED irradiation for 24h. The effects of phototherapy are expressed as ratios of serum total (TB) and unbound (UB) bilirubin before and after exposure to each LED. Urinary 8-hydroxy-2'-deoxyguanosine (8-OHdG) was measured by HPLC before and after exposure to each LED to determine photo-oxidative stress. RESULTS:Values 1.00), respectively. CONCLUSIONS:Blue plus green phototherapy is as effective as blue phototherapy and it attenuates irradiation-induced oxidative stress. PRACTICE IMPLICATIONS:Combined blue and green spectra might be effective against neonatal hyperbilirubinemia.博士（医学）・乙第1371号・平成27年11月27日Copyright © 2015 Elsevier Ireland Ltd. All rights reserved

慢性肺疾患の早産児におけるプロテインC経路 : 前向き研究

Background: Chronic lung disease (CLD) is a major neonatal pulmonary disorder associated with inflammation. Recent studies have shown that protein C anticoagulant pathways, such as those for protein C (PC), protein S (PS), and thrombomodulin (TM), could be useful indices for reflecting pulmonary injury. However, the involvement of these factors in preterm infants with very low birthweight (VLBW) who have developed CLD remains to be investigated. Here, we investigated whether PC pathway-related factors could predict the development of CLD in preterm infants with VLBW. Methods: We collected plasma samples from 26 preterm infants with VLBW (13 each from those with and without CLD) at the time of birth and measured TM, PC, and PS levels in their plasmas. We analyzed prospectively the relationship between these factors in infants with and without CLD. Results: There were significant differences in gestational age, birthweight, Apgar score (5 min), and duration of mechanical ventilation between the CLD and non-CLD groups. No significant differences in the PC and PS levels at birth were observed between the two groups, whereas the TM levels in the CLD group were significantly higher than those in the non-CLD group (P = 0.013). The TM levels correlated with gestational age and duration of mechanical ventilation. However, covariance analysis demonstrated that gestational age was significantly associated with TM levels, and consequently, development of CLD was not associated with TM level at birth. Conclusions: Thrombomodulin, PC, and PS levels at birth could not predict the development of CLD in preterm infants with VLBW.博士（医学）・甲第850号・令和4年9月28日© 2022 Japan Pediatric Society.This is the peer reviewed version of the following article: [https://onlinelibrary.wiley.com/doi/10.1111/ped.15221], which has been published in final form at [https://doi.org/10.1111/ped.15221].
