A study on students' idears about the school syllabus
1995年4月に初めての本学のシラバス(講義要覧)が発行され、学生に配布された。本報は約1年後の1996年2月の試験期間中にシラバスに対する学生の意見を問うために行われたアンケート調査の結果をまとめたものである。回答を寄せた学生は435人で、在籍学生の89.0%であった。よく利用したとする学生は18.2%、数回利用したとする学生は67.6%であった。学生の使用目的はテストの準備や履修科目の決定のためであった。以上のことから、現在のシラバスは学生が日常的により活用するためにはさらに教師が改善、工夫する必要があると思われた。The first syllabus of the School was published and distributed to all of the students in April,1995. Ten months later during the term examination, an opportunity arouse to question the sudents about their idears for the syllubus. A survery of all of the students was carried out and 435 students (89.0%) responded to it. They generally utilized it well, especially to decide which subjects they will take, to find out about the textbooks that will be used, and how to prepare for the examination. However it was found not to be sufficient for their daily use. Teachers therefore must make a greater effort in giving information about their lecture
Fruit scent and observer colour vision shape food-selection strategies in wild capuchin monkeys
The senses play critical roles in helping animals evaluate foods, including fruits that can change both in colour and scent during ripening to attract frugivores. Although numerous studies have assessed the impact of colour on fruit selection, comparatively little is known about fruit scent and how olfactory and visual data are integrated during foraging. We combine 25 months of behavioural data on 75 wild, white-faced capuchins (Cebus imitator) with measurements of fruit colours and scents from 18 dietary plant species. We show that frequency of fruit-directed olfactory behaviour is positively correlated with increases in the volume of fruit odours produced during ripening. Monkeys with red-green colour blindness sniffed fruits more often, indicating that increased reliance on olfaction is a behavioural strategy that mitigates decreased capacity to detect red-green colour contrast. These results demonstrate a complex interaction among fruit traits, sensory capacities and foraging strategies, which help explain variation in primate behaviour.https://www.nature.com/articles/s41467-019-10250-9Published versio
Local Gene Delivery System by Bubble Liposomes and Ultrasound Exposure into Joint Synovium
Recently, we have developed novel polyethylene glycol modified liposomes (bubble liposomes; BL) entrapping an ultrasound (US) imaging gas, which can work as a gene delivery tool with US exposure. In this study, we investigated the usefulness of US-mediated gene transfer systems with BL into synoviocytes in vitro and joint synovium in vivo. Highly efficient gene transfer could be achieved in the cultured primary synoviocytes transfected with the combination of BL and US exposure, compared to treatment with plasmid DNA (pDNA) alone, pDNA plus BL, or pDNA plus US. When BL was injected into the knee joints of mice, and US exposure was applied transcutaneously to the injection site, highly efficient gene expression could be observed in the knee joint transfected with the combination of BL and US exposure, compared to treatment with pDNA alone, pDNA plus BL, or pDNA plus US. The localized and prolonged gene expression was also shown by an in vivo luciferase imaging system. Thus, this local gene delivery system into joint synovium using the combination of BL and US exposure may be an effective means for gene therapy in joint disorders
Faculties' ideas to the school syllabus
シラバスは、その内容も含めて、まだ教官にも、学生にもなじみのない言葉である。著者らは、1994年、初めてのシラバス(講義要覧)を刊行した。このシラバスの中では、1人もしくは数人の教官によって、1教科・1学期分の講義の概要が各1ページの中に記載され、その枠組みは、基本的事項以外に、抗議の目標、授業計画、授業計画、教科書、参考書、授業の進め方、評価の方法、教官のメッセージから成るものであった。このシラバス作成に参加した専任教官45人及び非常勤教官107人、計153人に対し、調査表によってシラバス作成に関する意見を求めた結果、117人(77.0%)の教官が解答を寄せた。その結果は次のようなものであった。1.今回の作成計画以前にシラバスについて認識があった者は44.5%であった。しかし、シラバスの今後の発行に関しては94.9%の者が賛成であった。今回の枠組みについてはほとんどの者が肯定的であった。2.学生による授業評価については、約半数(52.7%)が賛成であるが、時期尚早とする者が41.8%いた。The term 'syllabus' and its concept are not familiar to university faculty members and students in Japan. Authors who belonged to School of Health Sciences Okayama University, published the first syllabus in 1994. In this syllabus, an outline of each course for a semester was shown by one or a few faculty members. The framework consisted of the mark of the subject, schedule, textbook, reference book, how to teach, how to grade and message to students, besides basic information. Forty-five full-time faculty members and 107 part-time faculty members were asked about their ideas for the syllabus through a questionnaire survey by mail and 119 faculty members (78.3%) responded to it. Only fifty-three faculty members (44.5%) had known the term 'syllabus' before the time when they started to talk about it or were asked to write it. But after their presenting syllabi, 104 faculty members (87.4%) agreeded to continue publishing and they were affirmative to framework as it was proposed this time. As for evaluation of subject by students, about half of faculties (52.7%) agreeded and 51.8% of them replied that were not mature enough for it yet
Compartment Syndrome after Prostatectomy
Robot-assisted laparoscopic prostatectomy (RALP) for prostate cancer was introduced in 2000 and rapidly gained popularity. The Da Vinci Surgical System® can ensure improved local control of cancer and fewer perioperative complications. However, RALP is performed in the steep-Trendelenburg position (a combination of lithotomy and head-down tilt position / Lloyd-Davies position) to obtain a good surgical view, and as a result, well leg compartment syndrome (WLCS) can become a serious complication of RALP. Here, we report a case of WLCS after RALP. A 75-year-old man underwent surgery for prostate cancer and immediately complained of pain and numbness after surgery. The pressure of the four leg compartments increased. Ultimately, we diagnosed the patient with WLCS in his right leg, and an emergency fasciotomy was performed. He completely recovered with no permanent disability and was discharged one month after rehabilitation. Although WLCS after RALP is a rare and severe complication, the patient recovered completely with early diagnosis and intervention. Measuring the compartment pressure is useful when the patient is drowsy immediately after recovery from anesthesia. Preventing WLCS requires identifying this condition as a potential complication of RALP and all urologic surgeries performed in the lithotomy position
Translation and validation of a Japanese version of the irritable bowel syndrome-quality of life measure (IBS-QOL-J)
AIMS: To compare quality of life (QOL) for patients with irritable bowel syndrome (IBS) between the U.S. and Japan, it is indispensable to develop common instruments. The IBS-QOL, which is widely used in Western countries, was translated into Japanese as there has been a lack of Japanese disease-specific QOL measures for IBS. METHODS: The original 34 items of the IBS-QOL were translated from English into Japanese through two independent forward translations, resolution, back translation, and resolution of differences. Forty nine patients who had GI symptoms but did not have any organic diseases (including 30 IBS patients diagnosed by Rome II criteria) were recruited from Tohoku University Hospital in Sendai, Japan and completed a Japanese version of the IBS-QOL (IBS-QOL-J) concomitant with a Japanese version of the IBS severity index (IBSSI-J) twice within 7–14 days. RESULTS: The IBS-QOL-J demonstrated high internal consistency (Cronbach's alpha; 0.96) and high reproducibility (intraclass correlation coefficient; 0.92, p < 0.001). Convergent analyses confirmed that the overall score of IBS-QOL-J was significantly correlated with overall severity of IBS symptoms on the IBSSI-J (r = -0.36, p = 0.01) and with the individual items on the IBSSI-J that assess interference with life in general (r = -0.47, p = 0.001) and dissatisfaction with bowel habits (r = -0.32, p < 0.05). Eight patients who reported continuous abdominal pain in the past 6 months had significantly lower scores in the IBS-QOL-J than those who did not (53.7 +- 12.7 vs. 73.6 +- 19.5, p < 0.01). Age, sex, education or marital status did not affect scores on the measure. CONCLUSION: The IBS-QOL-J is a reliable instrument to assess the disease-specific QOL for IBS. Considering cross-cultural comparison, this measure is likely to be a valuable tool to investigate the QOL in Japanese patients with IBS
Primary leiomyoma of the bladder
The case presented is of a 47-year-old patient with an extravesical pedunculated bladder leiomyoma, which was difficult to distinguish from a retroperitoneal tumor. Preoperatively, it was suspected to be a retroperitoneal tumor and a laparotomy with tumor resection was performed. lntraoperatively, the bladder and tumor were connected by a cord-like tissue. A retrospective review of preoperative images revealed that cord-like tissue, identified intraoperatively, was also present. Bladder leiomyomas can grow as extravesical pedunculated tumors. Therefore, when the continuity between the bladder and tumor is only a cord-like object, the finding of continuity is useful to diagnose with bladder leiomyoma
Nuclear abnormalities in aspirated thyroid cells and chromosome aberrations in lymphocytes of residents near the Semipalatinsk Nuclear Test Site
Chromosomal studies in peripheral lymphocytes from 63 residents near the Semipalatinsk nuclear test site, at ages of 52–63 years old, were performed in 2001–2002. A higher rate of chromosome aberrations was observed in the two contaminated villages, Dolon and Sarjal, compared with the control village,
Kokpekti. Moreover, a relationship of frequency of cells with radiation induced chromosome aberrations and the previously estimated exposure dose was observed. Furthermore, apparent nuclear abnormalities (ANA) of thyroid follicular cells were studied in 30 out of 63 residents, who were examined for chromosome aberrations. A higher rate of ANA was also found in the residents in the exposed villages compared with those in the control village. These results suggest radiation effects both on the chromosomes in
peripheral lymphocytes and on the follicular cells in the thyroid

Mechanical Stress Activates Smad Pathway through PKCδ to Enhance Interleukin-11 Gene Transcription in Osteoblasts
BACKGROUND: Mechanical stress rapidly induces ΔFosB expression in osteoblasts, which binds to interleukin (IL)-11 gene promoter to enhance IL-11 expression, and IL-11 enhances osteoblast differentiation. Because bone morphogenetic proteins (BMPs) also stimulate IL-11 expression in osteoblasts, there is a possibility that BMP-Smad signaling is involved in the enhancement of osteoblast differentiation by mechanical stress. The present study was undertaken to clarify whether mechanical stress affects BMP-Smad signaling, and if so, to elucidate the role of Smad signaling in mechanical stress-induced enhancement of IL-11 gene transcription. METHODOLOGY/PRINCIPAL FINDINGS: Mechanical loading by fluid shear stress (FSS) induced phosphorylation of BMP-specific receptor-regulated Smads (BR-Smads), Smad1/5, in murine primary osteoblasts (mPOBs). FSS rapidly phosphorylated Y311 of protein kinase C (PKC)δ, and phosphorylated PKCδ interacted with BR-Smads to phosphorylate BR-Smads. Transfection of PKCδ siRNA or Y311F mutant PKCδ abrogated BR-Smads phosphorylation and suppressed IL-11 gene transcription enhanced by FSS. Activated BR-Smads bound to the Smad-binding element (SBE) of IL-11 gene promoter and formed complex with ΔFosB/JunD heterodimer via binding to the C-terminal region of JunD. Site-directed mutagenesis in the SBE and the AP-1 site revealed that both SBE and AP-1 sites were required for full activation of IL-11 gene promoter by FSS. CONCLUSIONS/SIGNIFICANCE: These results demonstrate that PKCδ-BR-Smads pathway plays an important role in the intracellular signaling in response to mechanical stress, and that a cross-talk between PKCδ-BR-Smads and ΔFosB/JunD pathways synergistically stimulates IL-11 gene transcription in response to mechanical stress
