This study proposes a system in which learners can find targeted learning contents efficiently and clarifies the improvement of the efficiency by using the system through simulation and learning in practice. In this system, learning support information managed by a database is defined as information to link learners and learning contents. Learning support information consists of keywords of learning contents, location and ordering information for learning contents. By using this system learners can find not only targeted learning contents but also related additional learning contents efficiently. Moreover it is possible to generate new curriculums using keywords and learning support information.

The cell fate determination in ascidian embryos is mediated by various cell interactions. Two sensory pigment cell precursors constitute an equivalence group, in which the ocellus (eye) pathway is the dominant fate. It is suggested that the unique cell interaction, which is called lateral inhibition, is involved in determination events of these equivalent cells. It is likely that the mode of specification which utilizes the lateral inhibition within equivalent cells plays a fundamental role during early embryogenesis in both invertebrates and vertebrates.

子宮頸癌は30歳代に罹患ピークがあり,年間約7000人が発症し,約3000人が死亡する癌である.ヒトパピローマウイルス(HPV)が原因であることは周知であり,HPVを標的とした癌免疫療法が期待されてきた.20年以上の開発の歴史の中で製剤化されたものはない.我々は,粘膜免疫を誘導する免疫療法を開発し,子宮頸癌前癌病変(CIN3)を対象とした臨床試験を実施した.HPV癌蛋白質E7を表出した乳酸菌をCIN3患者に経口投与し,HPV特異的細胞性免疫を腸管粘膜に誘導し,腸管粘膜由来のintegrin beta7陽性リンパ球を子宮頸部病変に見出した.そのうち,HPVE7特異的IFNgamma産生リンパ球の子宮頸部粘膜の集積と臨床的病変退縮は相関した.この臨床試験のデータをもとに,E7表出乳酸菌を改良し,現在第二世代乳酸菌ワクチンを製剤化している.一方,integrin beta7陽性リンパ球が子宮頸部粘膜上皮にホーミングし,かつ集積することがCIN3病変を排除することに寄与することを見出したので,細胞療法として,これらの細胞に山中因子を導入するT-iPS技術を応用することをめざしている.本講演では,これまでの粘膜免疫を介した新しい免疫療法の臨床成果と今後の新技術(特に再生医療)との複合について紹介したい.

In this paper, we propose an algorithm to estimate sleep quality based on a heart rate variability using chaos analysis. Polysomnography(PSG) is a conventional and reliable system to diagnose sleep disorder and to evaluate its severity and therapeatic effect, by estimating sleep quality based on multiple channels. However, a recording process requires a lot of time and a controlled environment for measurement and then an analyzing process of PSG data is hard work because the huge sensed data should be manually evaluated. On the other hand, it is focused that some people make a mistake or cause an accident due to lost of regular sleep and of homeostasis these days. Therefore a simple home system for checking own sleep is required and then the estimation algorithm for the system should be developed. Therefore we propose an algorithm to estimate sleep quality based only on a heart rate variability which can be measured by a simple sensor such as a pressure sensor and an infrared sensor in an uncontrolled environment, by experimentally finding the relationship between chaos indices and sleep quality. The system including the estimation algorithm can inform patterns and quality of own daily sleep to a user, and then the user can previously arranges his life schedule, pays more attention based on sleep results and consult with a doctor.

Formaldehyde is a well-known air impurity. The possibility was investigated in this study that pharmaceutical excipients commonly used in oral solid dosage forms might also be sources of formaldehyde. The results showed that formaldehyde is generated by the excipients lactose, D-mannitol, microcrystalline cellulose, low-substituted hydroxypropylcellulose, magnesium stearate and light anhydrous silicic acid. Since the quality and safety of pharmaceutical products can be significantly affected by the presence of formaldehyde, various amines were then investigated for their ability to decrease levels of formaldehyde using an aqueous solution system. Of the four amines investigated, only meglumine proved capable of reducing formaldehyde levels. The reaction product between formaldehyde and meglumine was obtained by fractionation using the preparative HPLC system and the structure was clarified by 1H-, 13C-NMR, various types of two-dimensional NMR and mass spectroscopy. The reaction product was determined to be a compound with a 1,3-oxazinane skeleton and containing one more carbon than meglumine. It was presumed that formaldehyde reacted with the secondary amino group in meglumine to form the reaction product via an iminium salt intermediate by cyclization. As meglumine is permitted to be used as a pharmaceutical excipient in both oral and parenteral dosage forms by regulations worldwide, the addition of meglumine to pharmaceutical products can be expected to contribute to the stabilization of many drug substances.

A programming ability has been required in many areas because of the progress of information technology. As a result, a programming education is becoming more important than ever before. However, there is an issue that programming exercises do not work effectively when they are introduced to entry level students. The introduction of programing education should be more attractive so that students can become interested in programming and engage in it independently. In this report, we suggest a method of small-step exercises in order to provide a learning environment in such a way that students work on exercises independently as well as actively. The questionnaire survey shows the method we implemented is very effective.

We developed a scale to measure time management and assessed its reliability and validity. We then used this scale to examine the impact of time management on psychological stress response. In Study 1-1, we developed the scale and assessed its internal consistency and criterion-related validity. Findings from a factor analysis revealed three elements of time management, “time estimation,” “time utilization,” and “taking each moment as it comes.” In Study 1-2, we assessed the scale’s test-retest reliability. In Study 1-3, we assessed the validity of the constructed scale. The results indicate that the time management scale has good reliability and validity. In Study 2, we performed a covariance structural analysis to verify our model that hypothesized that time management influences perceived control of time and psychological stress response, and perceived control of time influences psychological stress response. The results showed that time estimation increases the perceived control of time, which in turn decreases stress response. However, we also found that taking each moment as it comes reduces perceived control of time, which in turn increases stress response.

Even after Kudoa septempunctata parasitic in Olive flounder was found as a cause of food poisoning, similar cases of unknown cause were still taking place. Juvenile Pacific bluefin tuna (JPBT, hereafter) is often presented in those cases and it is suspected that K. hexapunctata parasitic in JPBT would be pathogenic for humans. We attempted to detect K. hexapunctata from JPBT leftover and patients' feces in 4 cases in Niigata prefecture from 2011 to 2014. In addition, we also investigated excretion of K. hexapunctata into the feces after intake of JPBT on a trial basis. The 4 cases occurred during summer from July to September. K. hexapunctata was detected from JPBT leftover and patients' feces; therefore, it was estimated that K. hexapunctata could be parasitic in JPBT eaten in all those cases. Furthermore, we also found that JPBT and Olive flounder were eaten together in 2 cases, but K. septempunctata was not detected from patients' feces. The detection rate of K. hexapunctata from patients' feces was 86% for feces collected within 3 days after meal, but it was lowered 25% for feces collected after 1 week. The quantity of K. hexapunctata excreted into feces after intake of JPBT on a trial basis tended to be declining with time, and then K. hexapunctata was detected in feces up to approximately 3 days after intake of JPBT. From those results, a fecal examination would be important as collecting feces after meal or during an early stage, and feces collected within 3 days after meal could be appropriate for the examination. Cases in relation to JPBT are similar to those of food poisoning caused by K. septempunctata and it is suspected that K. hexapunctata might be the cause. For K. hexapunctata, it would be necessary to accumulate and examine the case data while clarifying its pathogenicity.

Objective The causes of fever of unknown origin (FUO) vary depending on the region and time period. We herein present a study of patients with classic FUO where we investigated differences based on patient background factors, such as age and causative diseases, and changes that have occurred over time. Methods We extracted and analyzed data from the medical records of 256 patients ≥18 years old who met the criteria for classic FUO and were hospitalized between August, 1994 and December, 2012. Results The median age of the patients was 55 years (range: 18-94 years). The cause of FUO was infection in 27.7% of the patients (n=71), non-infectious inflammatory disease (NIID) in 18.4% (47), malignancy in 10.2% (26), other in 14.8% (38), and unknown in 28.9% (74). The most common single cause was human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) (n=17). NIID and malignancy were more common in patients ≥65 years old than in patients <65 years old. During 2004-2012, compared to 1994-2003, infections and "other" causes were decreased, whereas NIID, malignancy, and unknown causes were increased. Conclusion FUO associated with HIV/AIDS is increasing in Japan. In addition, as in previous studies in Japan and overseas, our study showed that the number of patients in whom the cause of FUO remains unknown is increasing and exceeds 20% of all cases. The present study identified diseases that should be considered in the differential diagnosis of FUO, providing useful information for the future diagnosis and treatment of FUO.
