Ludwigia grandiflora (Michx.) Greuter & Burdet is an invasive aquatic plant native to an area ranging from the southeastern United States to South America. In previous reports, L. grandiflora in Lake Biwa has been identified as L. grandiflora subsp. grandiflora, a hexaploid subspecies (2n = 48) or L. grandiflora sensu lato. Species of Ludwigia sect. Jussiaea, are morphologically very similar. Morphological characters, especially floral characters and cytology (chromosome number) have been used to identify species and subspecies. In our study, the morphological characteristics of L. grandiflora in Lake Biwa substantially corresponded to those of L. grandiflora subsp. hexapetala (Hook. & Arn.) G. L. Nesom & Kartesz, a decaploid (2n = 80) subspecies. The chromosome number of L. grandiflora in Lake Biwa was 2n = ca. 80, the same as in L. grandiflora subsp. hexapetala (2n = 80). Importantly, L. grandiflora in Lake Biwa is not L. grandiflora subsp. grandiflora, but rather L. grandiflora subsp. hexapetala. This re-identification has implications for management in Lake Biwa, since the life history of L. grandiflora subsp. hexapetala has been studied in Europe.

This paper aims to clarify the circumstances of the housing problem in Tokyo after Kanto Daishinsai [the Great Kanto Earthquake of 1923] mainly in relation to the supply and demand on the rental housing market. Based on the marked increase in housing demand following the earthquake, excessive housing investments were made in the suburbs of Tokyo city. However, the increase in housing supply in Tokyo city, on the one hand, and the increase in tenants due to intensification of the recession, on the other, widened the gap between supply and demand by area. The focus of the housing problem shifted from an absolute lack of housing into a problem of affordability. By the end of the 1920s, dissatisfaction intensified among low-income tenants who were shut out of the private rental housing market. From 1929 to 1930, rental rates decreased in general under the influence of a decline in prices and a movement for rent reduction.

On December 31, 2019, the Wuhan Municipal Health Commission announced an outbreak of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), China is now at a critical period in the control of the epidemic. The Chinese Government has been taking a series of rapid, comprehensive, and effective prevention and control measures. As the pandemic has developed, a fact has become apparent: there is a serious dearth of emergency medical supplies, and especially an extreme shortage of personal protective equipment such as masks and medical protective clothing. This is one of the major factors affecting the progress of epidemic prevention and control. Although China has made great efforts to strengthen the ability to quickly respond to public health emergencies since the SARS outbreak in 2003 and it has clarified requirements for emergency supplies through legislation, the emergency reserve supplies program has not been effectively implemented, and there are also deficiencies in the types, quantity, and availability of emergency medical supplies. A sound system of emergency reserve supplies is crucial to the management of public health emergencies. Based on international experiences with pandemic control, the world should emphasize improving the system of emergency reserve medical supplies in the process of establishing and improving public health emergency response systems, and it should promote the establishment of international cooperative programs to jointly deal with public health emergencies of international concern in the future.

DNA methylation is the covalent modification of methyl groups to DNA mostly at CpG dinucleotides and one of the most studied epigenetic mechanisms that leads to gene expression variability without affecting the DNA sequence. Genome-wide analysis of DNA methylation identified the signatures that could define subtypes of human lymphoma patients. The objective of this study was to conduct the genome-wide analysis of DNA methylation in dogs with gastrointestinal lymphoma (GIL). Genomic DNA was extracted from endoscopic biopsies from 10 dogs with GIL. We performed Digital Restriction Enzyme Assay of DNA Methylation (DREAM) for genome-wide DNA methylation analysis that could provide highly quantitative information on DNA methylation levels of CpG sites across the dog genome. We successfully obtained data of quantitative DNA methylation level for 148,601–162,364 CpG sites per GIL sample. Next, we analyzed 83,132 CpG sites to dissect the differences in DNA methylation between GIL and normal peripheral blood mononuclear cells (PBMCs). We found 383–3,054 CpG sites that were hypermethylated in GIL cases compared to PBMCs. Interestingly, 773 CpG sites including promoter regions of 61 genes were identified to be commonly hypermethylated in more than half of the cases, suggesting conserved DNA methylation patterns that are abnormal in GIL. This study revealed that there was a large number of hypermethylated sites that are common in most of canine GIL. These abnormal DNA methylation could be involved in tumorigenesis of the canine GIL.

The original description of Pterygotrigla cajorarori Richards and Yato, 2012, based on eight specimens from the western Pacific Ocean, including one Japanese specimen, indicated hyperostosis in the rostral projection, head bones (infraorbital, frontal, and parietal), post temporal spine, humeral spine, and the 2nd–4th first dorsal-fin spines, although variations in these characters were poorly documented. Thirteen specimens (including two paratypes) of P. cajorarori collected from southern Japan, the South China Sea, and Indonesia were found to vary individually in the degree of hyperostosis in the rostral projection, mesethmoid, lateral ethmoid, frontal, sphenotic, pterotic, and infraorbital bones, whereas the condition was not prominent in the parietal and posttemporal bones, or the humeral spines. However, hyperostosis was newly found in the 5th and 6th dorsal-fin spines and pelvic-fin spine. A detailed description of fresh coloration (previously unknown) in P. cajorarori is also given.

Objective: We conducted a meta-analysis on the suppressive effect of resistant maltodextrin on post-prandial blood glucose elevation, which is approved in Japan as food for specified health use, and the following is allowed to be indicated on the label “it is suitable for consumption by those who are concerned about their post-prandial blood glucose levels because the absorption of sugars is abated by the action of dietary fiber (resistant maltodextrin).”Method: Our literature search covered Ichushi-Web (Japan Medical Abstracts Society), Japan Science and Technology Information Aggregator, Electronic (J-stage), Google Scholar, and PubMed databases and extracted English and Japanese publications on randomized, double-blind, controlled studies comparing resistant maltodextrin and a control in Japanese subjects for the reduction of areas under the blood glucose response curves at 30, 60, and 120 min after eating as an efficacy index.Result: Among these publications, four articles with a Jadad score (an assessment of the quality of randomized controlled studies) of ≥ 3 were included in the meta-analysis.  Significant inhibitory effects were confirmed from areas under the blood glucose response curves at 30, 60, and 120 min after eating in the meta-analysis that was performed to evaluate the effects of resistant maltodextrin on post-prandial blood glucose elevation in Japanese individuals.Conclusion: However, we were not able to test for publication bias because the number of extracted publications was small, and thus, additional research and case studies are warranted.

軽度認知障害 (mild cognitive impairment: MCI)は,Petersen により提唱された疾患である. 1. 認知機能は正常とはいえないが,認知症の診断基準も満たさない.2. 本人または情報提供者から認知機能低下の訴えがある.3. 複雑な日常生活動作の障害は最低限にとどまり,基本的な日常生活機能は正常である,という状態である.罹患率は 65 歳以上の 10-20%で,Alzheimer´s disease (AD) の約 1.5-2 倍である.MCI は記憶障害の有無で amnestic MCI (健忘性 MCI) と non-amnestic MCI (非健忘性 MCI) に分類される.さらに認知機能障害が単一か複数かで single domain か multiple domain に分類される.脳血管障害,認知機能に影響を及ぼす神経系の疾患,精神疾患,全身的な内科疾患,薬物中毒などが原因疾患となる.MCI 全体では約 70%が認知症に進行する.特に健忘性 MCI の多くは進行し,無治療であれば 4 年後には 50%,最終的には 90%以上が AD に進展する.診断の確実度として,アミロイド b (Ab) 蓄積 (アミロイド PET 陽性または脳脊髄液の Ab 42 の低下) と神経細胞障害 (脳脊髄液 tau /リン酸化 tau 増加または FDG-PET で側頭・頭頂葉の糖代謝の低下または MRI による側頭・頭頂葉の萎縮) が示されている.これらのバイオマーカ ーは AD への進展因子でもある.健忘性 MCI の段階ですでに Ab が脳内に蓄積していると考えられている.Abを標的とした薬剤が開発中であるが,順調とはいえない.現時点では MCI から AD への進行を予防する根治的治療法はない.適度な運動とビタミンを多く含むバランスのとれた食事の摂取が,ある程度効果があるといわれている.

The problem of retrograde amnesia (R. A. ) has long been discussed but certain details yet remained unclarified. For seven years, the author has investigated 847 cases of the head injured presenting R. A. in the Neuro-psychiatric Department of Kansai Medical School. In this survey, however, the cases in the acute stage of the injury and those with amnestic syndrome have carefully been excluded from the materials.The results are as follows:1) The correlation between R. A. and post-traumatic amnesia (P. T. A. ) is hardly recognized as Russell has already pointed it out. R. A. is seldom found in cases with P. T. A. of short duration (less than an hour). In addition, the presence of long-lasting R. A. has no direct relationship with the duration of P. T. A.2) Precise clinical investigation of 13 cases with fairly long-lasting R. A. (more than an hour) has resulted in the following findings.a) Statistically, it might be probable that manifest and long-lasting R. A. tended to be found in car drivers.b) Various offenses of the traffic law or responsibility due to unskilful driving technique and consequently certain feelings of guilt are frequently found in those cases, and expectation of compensation is never observed among them.c) Organic damage of brain, especially of m nemic system, is not always suspected in them.d) The presence of such type of R. A. might rather be considered in connection with character traits than with the factors of intelligence of the patients.e) Treatment of R. A. was intended by means of psycho therapy in eight cases: sufficient or remarkable recovery of memory were obtained in two cases by intensive suggestion and five by hypnotherapy.

高齢化など様々な要因で,独居生活を選択あるいは余儀なくされている人は少なくない.孤独な生活により感情状態が悪化し,うつ病や心の病にかかるなど深刻な問題である.一方,心理学者ウィリアム・ジェイムズの言説で,「人は幸福であるが故に笑うのではなく,笑うが故に幸福である」という考え方がある.これは笑顔形成が感情状態を向上させる可能性を示唆している.そこで本論文では,日常生活のなかで積極的に笑顔をつくることを促進し,感情状態の向上を支援するシステム「HappinessCounter」を提案する.笑顔促進のために,ユーザが日常的に行う作業時に笑顔形成を促し,フィードバックを与えたり,ソーシャルネットワークサービスなどと連携させることで,より積極的に笑顔形成を支援し,感情状態の向上を目指す.さらに試作したシステムを実際の日常生活で利用してもらい評価実験を行った.実験結果から,本システムが笑顔促進に効果的に働き,また家族間のコミュニケーションにも影響があったことが窺えた.

ポット底面の空気根切り処理の違いが,苗の根系成長に与える影響を明らかにすることを目的とし,コナラとネズミモチの稚苗を底面の通気及び排水性の異なるポットに鉢上げしてから,615日間育成した。その結果,コナラについては,主根のルーピング防止効果が認められた。また,ネズミモチは,ルーピングの完全な防止効果は認められなかったものの,抑制効果は認められた。このことから,ポット底面の形状の違いがコナラおよびネズミモチの根系成長に対して顕著な影響を与えたと推測され,空気根切りを用いた苗木育成のルーピング防止または抑制に対する有効性が認められた。
