List of Ishigaki Rin’s Works 1935-1943

Ishigaki Rin (1920-2004) is one of the well-known postwar poet in Japan. As it is only 15 years since she passed away, comprehensive list of her works is yet to be published. This list is a philological research on the works of Ishigaki Rin from 1935 through 1943. During this period, she published her works in various forms such as poem, tanka, haiku and essay. Because she was young and unknown, most of her publications appeared in magazines for female teenagers. Shojogaho and Danso were her main stage for her early literary activities. We, two authors of this list, collected all the photocopies of the works in this list. Our purpose would be fulfilled if a complete list of Ishigaki Rin’s works appear in near future

Growth of potassium tantalate (KTaO3) crystals by directional solidification

Potassium tantalate (KTaO3) crystals were grown by directional solidification from various compositions of K2CO3-Ta2O5 melt. When raw materials with the stoichiometric composition (K2CO3:Ta2O5=50:50 mol%) were used, K6Ta10.8O30 crystallized as the primary phase, indicating that KTaO3 melts incongruently. K6Ta10.8O30 is newly found in the K2CO3-Ta2O5 phase diagram and it is stably synthesized at temperatures above 1200 degrees C. In contrast, KTaO3 crystallized when the ratio of K2CO3 was more than 51.5 mol%. There were three kinds of color in the KTaO3-crystallized portions: milky white, colorless transparent and pale yellow. Based on these results, the phase diagram of the K2CO3-Ta2O5 system around the stoichiometric composition of KTaO3 is proposed. (C) 2013 Elsevier B.V.

Evaluation of 3,3′-Triazolyl Biisoquinoline N,N′-Dioxide Catalysts for Asymmetric Hydrosilylation of Hydrazones with Trichlorosilane

A new class of axial-chiral biisoquinoline N,N′-dioxides was evaluated as catalysts for the enantioselective hydrosilylation of acyl hydrazones with trichlorosilane. While these catalysts provided poor to moderate reactivity and enantioselectivity, this study represents the first example of the organocatalytic asymmetric reduction of acyl hydrazones. In addition, the structures and energies of two possible diastereomeric catalyst–trichlorosilane complexes (2a–HSiCl3) were analyzed using density functional theory calculations

Cytology Reporting System for Lung Cancer from the Japan Lung Cancer Society and the Japanese Society of Clinical Cytology: An Extensive Study Containing More Benign Lesions

Introduction: The Japan Lung Cancer Society (JLCS) and the Japanese Society of Clinical Cytology (JSCC) have proposed a new four-tiered cytology reporting system for lung carcinoma (JLCS-JSCC system). Prior to the proposal, the Papanicolaou Society of Cytopathology (PSC) had proposed a revised reporting system (PSC system), which comprises the “neoplastic, benign neoplasm, and low-grade carcinoma” category (N-B-LG category), in addition to the 4 categories of the JLCS-JSCC system. This study aimed to evaluate the interobserver agreement of the JLCS-JSCC system with an additional dataset with more benign lesions in comparison with the PSC system. Methods: We analyzed 167 cytological samples, which included 17 benign lesions, obtained from the respiratory system. Seven observers classified these cases into each category by reviewing one Papanicolaou-stained slide per case according to the JLCS-JSCC system and PSC system. Results: The interobserver agreement was moderate in the JLCS-JSCC (k = 0.499) and PSC (k = 0.485) systems. Of the 167 samples, 17 samples were benign lesions: 7 pulmonary hamartomas, 5 sclerosing pneumocytomas, 2 squamous papillomas, one solitary fibrous tumor, one meningioma, and one lymphocytic proliferation. There were diverse sample types as follows: 11 touch smears, 3 brushing smears, 2 aspirations, and one sputum sample. Fourteen samples (82.3%) were categorized into “negative” or “atypical” by more than half of the observers in the JLCS-JSCC system. Conversely, 3 samples were categorized as “suspicious” or “malignant” by more than half of the observers in the JLCS-JSCC system. On the other hand, 11 samples (64.7%) were categorized into the N-B-LG category by more than half of the observers in the PSC system. Conclusions: The concordance rate in the JLCS-JSCC system was slightly higher than that in the PSC system; however, the interobserver agreement was moderate in both the JLCS-JSCC and PSC systems. These results indicate that both the JLCS-JSCC and PSC systems are clinically useful. Therefore, both systems are expected to have clinical applications. It may be important to integrate the 2 systems and construct a universal system that can be used more widely in clinical practice

緩和ケアにおける人材育成研修の成果と課題 : 修了生の看護実践・自己の姿勢への活用

A県における緩和ケアの研修を修了した修了生173名に、研修後の看護実践と自己の行動の変化について質問紙調査を行った。その結果、身体症状の緩和や傾聴、日常生活への支援に関する看護実践、自己の姿勢・態度の変容に活かしやすく、精神症状の緩和、遺族ケア、意思決定、地域連携に関する看護実践には活かしにくかった。一方、スキルアップの動機づけにもなっていた。今後は、難しいと感じる分野の研修内容・方法の検討、モチベーションの維持・向上のための環境調整やフォローアップの機会が必要であることが明らかになった

Finishing the euchromatic sequence of the human genome

The sequence of the human genome encodes the genetic instructions for human physiology, as well as rich information about human evolution. In 2001, the International Human Genome Sequencing Consortium reported a draft sequence of the euchromatic portion of the human genome. Since then, the international collaboration has worked to convert this draft into a genome sequence with high accuracy and nearly complete coverage. Here, we report the result of this finishing process. The current genome sequence (Build 35) contains 2.85 billion nucleotides interrupted by only 341 gaps. It covers ∼99% of the euchromatic genome and is accurate to an error rate of ∼1 event per 100,000 bases. Many of the remaining euchromatic gaps are associated with segmental duplications and will require focused work with new methods. The near-complete sequence, the first for a vertebrate, greatly improves the precision of biological analyses of the human genome including studies of gene number, birth and death. Notably, the human enome seems to encode only 20,000-25,000 protein-coding genes. The genome sequence reported here should serve as a firm foundation for biomedical research in the decades ahead
