Curated genome annotation of Oryza sativa ssp. japonica and comparative genome analysis with Arabidopsis thaliana

We present here the annotation of the complete genome of rice Oryza sativa L. ssp. japonica cultivar Nipponbare. All functional annotations for proteins and non-protein-coding RNA (npRNA) candidates were manually curated. Functions were identified or inferred in 19,969 (70%) of the proteins, and 131 possible npRNAs (including 58 antisense transcripts) were found. Almost 5000 annotated protein-coding genes were found to be disrupted in insertional mutant lines, which will accelerate future experimental validation of the annotations. The rice loci were determined by using cDNA sequences obtained from rice and other representative cereals. Our conservative estimate based on these loci and an extrapolation suggested that the gene number of rice is ~32,000, which is smaller than previous estimates. We conducted comparative analyses between rice and Arabidopsis thaliana and found that both genomes possessed several lineage-specific genes, which might account for the observed differences between these species, while they had similar sets of predicted functional domains among the protein sequences. A system to control translational efficiency seems to be conserved across large evolutionary distances. Moreover, the evolutionary process of protein-coding genes was examined. Our results suggest that natural selection may have played a role for duplicated genes in both species, so that duplication was suppressed or favored in a manner that depended on the function of a gene

Protocol for a multicentre, prospective observational study of elective neck dissection for clinically node-negative oral tongue squamous cell carcinoma (END-TC study)

Introduction: In early-stage oral tongue squamous cell carcinoma (OTSCC), elective neck dissection (END) is recommended when occult lymph node metastasis is suspected; however, there is no unanimous consensus on the risks and benefits of END in such cases. The management of clinically node-negative (cN0) OTSCC remains controversial. This study, therefore, aimed to evaluate the efficacy of END and its impact on the quality of life (QoL) of patients with cN0 OTSCC. Methods and analysis: This is a prospective, multicentre, nonrandomised observational study. The choice of whether to perform END at the same time as resection of the primary tumour is based on institutional policy and patient preference. The primary endpoint of this study is 3-year overall survival. The secondary endpoint are 3-year disease-specific survival, 3-year relapse-free survival and the impact on patient QoL. Propensity score-matching analysis will be performed to reduce selection bias. Ethics and dissemination: This study was approved by the Clinical Research Review Board of the Nagasaki University. The protocol of this study was registered at the University Hospital Medical Information Network Clinical Trials Registry. The datasets generated during the current study will be available from the corresponding author on reasonable request. The results will be disseminated internationally, through scientific and professional conferences and in peer-reviewed medical journals

看護系大学一校の成人看護学実習および老年看護学実習における看護学生の看護基本技術についてその見学または実施状況を明らかにし, 今後の講義・演習の内容や, 実習カリキュラムと実習施設, 実習指導の在り方等を検討するための基礎資料とすることを目的に, 文献等から選定した看護基本技術118項目の「見学」または「指導者の助言・監督下で実施」について調査した. 同大学で領域別看護学実習を履修した4年生のうち協力の得られた79名(回答率98.8%)のデータを分析した結果, 成人看護学実習・老年看護学実習の全般において, 環境整備, 清潔ケア, バイタルサイン測定, 病態・症状観察等の看護基本技術を見学または実施した学生が過半数を超えた. 一方, 呼吸, 排泄, 与薬, 救急, 症状・生体機能管理, 感染予防面の看護基本技術の見学または実施は, 全体の4分の1程度にとどまった. 学生が, 多様な治療を受ける患者の看護を学ぶことを通し, 臨地実習の場で見学や実施したことを振り返り, そして現象を関連付けて理解できる実習を編成することの重要性が示唆された.The purpose of this survey is to identify the current status of fundamental nursing skills performed by nursing students in adult and gerontological nursing practicums incorporated as part of a four-year baccalaureate nursing program. There were 118 survey items about fundamental nursing skills selected from the related literature. For each fundamental nursing skill the respondents were asked to answer, "have observed demonstration of this skill", "have performed this skill under the supervision of clinical nurse instructors" or "have not had any chance for observation or performance". Seventy-nine senior students (response rate: 98.8%) agreed to fill in and submit the survey sheet. The survey showed that more than half of the respondents had observed demonstration of, or had performed under supervision, such fundamental skills as management of the environment of care (cleanliness and safety of hospital beds and rooms), personal and hygiene care, vital sign measurement, assessment and monitoring of signs and symptoms in either adult or gerontological nursing practicum, or in both. In addition, about less than one-fourths of the respondents reported that they had observed demonstration of, or had performed under supervision, skills like respiratory care, elimination care, medication, monitoring and maintenance of vital functions and infection control. These results indicate the importance of arranging nursing practicums in such a way that students can learn a variety of nursing interventions and clinical skills in diverse care settings. Furthermore, nursing students need to be encouraged to learn through observation, performance under supervision and reflection so that they can understand the meaning of a variety of interconnected phenomena

Palliative care for elderly people with dementia in Melbourne

The purpose of this study was to investigate dementia and palliative care in Melbourne. In Melbourne, end-of-life care for elderly people with dementia is included in palliative care. Mainly, care is characterized by nurses carrying out palliative care such as pain control psychologically including prescribing painkillers; also derive there are pastoral care workers who help patients. Most nurses a sense of satisfaction after caring for a person with dementia in their final moments, but there are some nurses with little experience who become very emotional after a persons death and upset. Emotional care for staff is carried out by pastoral care workers or priests, and words of gratitude from families go a long way toward helping the nurses
