We evaluated the effectiveness of small group discussion (SGD) in association with a drug abuse prevention program for junior high school students. The students first received a lecture about drug abuse prevention, then participated in SGD. The discussion focused on how to take action when tempted to abuse drugs. We gave a questionnaire 3 times; before and after the lecture (before SGD), and after SGD. Seventy-seven students replied to these questionnaires. After the lecture, knowledge about drug abuse was improved and all students answered that they had never abused drugs. However, in answer to a different question, a few students noted that they might use drugs in some situations. We consider it necessary to give more consideration to this problem. After the lecture, 35.5% of the students felt that they had definitely acquired skills for drug abuse prevention, whereas after the SGD this was increased to 73.7%. In addition, more than 75% of the students answered that the SGD program was useful since the opinions of other students could be heard. These results suggest that more students acquired skills to prevent drug abuse by participation in SGD. Our findings showed that SGD was useful and that the students were able to more effectively understand important concepts related to drug abuse prevention.

Insulin resistance is a characteristic feature of type II diabetes as well as obesity. This insulin resistant state at the peripheral tissue level causes impaired glucose utilization, leading to hyperglycemia. Studies of antidiabetic agents by Takeda originated more than three decades ago when KK mice were introduced, followed by the development of a highly insulin-resistant animal model, KKAy mice. The first 2,4-thiazolidinedione derivative AL-321, which exhibited hypoglycemic effects in KKAy mice, was discovered by modification of the hypolipidemic agent AL-294 as a lead compound. Extensive structure-activity relationship studies on the analogues of AL-321 led to the selection of ciglitazone (ADD-3878) as a candidate for clinical evaluation. Ciglitazone, a prototypical compound in the series, was shown to normalize hyperglycemia, hyperinsulinemia, and hypertriglyceridemia in various insulin-resistant animal models without altering normoglycemia in nondiabetic animal models. However, it appeared that a more potent compound was needed for further clinical evaluation of this class of compound. Further study of this series of compounds led to the finding of pioglitazone (AD-4833) as a promising clinical candidate. Pioglitazone clearly ameliorates the abnormal glucose and lipid metabolism in diabetic patients and was marketed in the USA in August 1999 for the treatment of type II diabetes. Pioglitazone is now marketed in more than 40 countries world wide. Historical aspects of our studies on pioglitazone and its biological activities are described.

Recently, the procedure for surgical hand hygiene has been switching to a two-stage method and hand-rubbing method from the traditional hand-scrubbing method. Both the two-stage and hand-rubbing methods use alcohol-based hand-rubbing after hand washing. The former requires 5 min of antiseptic hand washing, and the latter 1 min of nonantiseptic hand washing. For a prolonged bactericidal effect in terms of surgical hand hygiene, chlorhexidine gluconate (CHG) has been noted due to its residual activity. However, no detailed study comparing the disinfection efficacy and prolonged effects according to different contents of CHG and the usage of alcohol-based hand-rubbing has been conducted. The glove juice method is able to evaluate disinfection efficacy and prolonged effects of the disinfectants more accurately because it can collect not only transitory bacteria but also normal inhabitants on hands. In the present study, we examined the disinfection efficacy and prolonged effects on alcohol-based hand-rubbing containing CHG by six hand-rubbing methods and three two-stage methods using the glove juice method. In both methods, 3 mL (one pump dispenser push volume) alcohol-based hand-rubbing solution containing 1% (w/v) CHG showed the highest disinfection efficacy and prolonged effects, and no significant difference was found between the hand-rubbing and two-stage methods. In the two methods of hand hygiene, the hand-rubbing method was able to save time and cost. Therefore, the data strongly suggest that the hand-rubbing method using a one pump dispenser push volume of alcohol-based hand-rubbing solution containing 1% (w/v) CHG is suitable for surgical hand hygiene.

Research into environmental dynamics of radioactive nuclides released by the Fukushima nuclear accident, especially radiocesium 137Cs (half-life, 30.1 years), is highly focused especially on diffusion processes of radiocesium into ecosystems, which is high-priority knowledge. Because of relatively sparse knowledge about the reallocation of radiocesium contained in organic matter in terrestrial ecosystems, the effects of diffused rediocesium into ecosystem cannot be accurately estimated. In this article, the terrestrial environmental dynamics of radiocesium mainly in the processes of plant uptake and the possibility of release from plants will be discussed. Plants uptake minerals from soil and these minerals are likewise ingested by animals that feed on plants, including humans. Therefore one of the main gateways of radiocesium into ecosystem is via plants. From the viewpoint of human dietary consumption, rice contamination with radiocesium has been energetically investigated and useful data are accumulating. Processes of radiocesium uptake mechanisms by plants are being researched using legumes, e.g. soybean. Speculation on the possibility of radiocesium release into forest atmosphere via plant activity will be introduced.

Medical staff, including physicians, nurses, pharmacists, nutritionists, laboratory medical technologists, social workers, and case managers, should act as a team to support patients with human immunodeficiency virus (HIV) infection. The therapeutic purpose of a potent cocktail of anti-HIV drugs is to maintain undetectable plasma levels of HIV over the long term. To achieve this, it is necessary to maintain treatment compliance. However, noncompliance frequently occurs because of a poor understanding of HIV therapy or difficulty in taking anti-HIV drugs. Thus pharmacists should contribute as HIV medical team members by providing medication counseling to ensure treatment compliance or delivering drug information to achieve successful HIV therapy. We describe the roles of pharmacists on HIV medical teams at Ehime University Hospital in examples of nutritional disorder or pregnant women with HIV.

In order to examine the effects of music on mood, we administered a survey to patients awaiting the preparation of their prescription medicines in pharmacy lounges. Two pharmacies took part in this study, both of which are in a metropolitan area treating fewer than 100 prescription sheets per day. Two hundred and fifty-two patients were divided into two groups: one group listened to background music (BGM) while waiting (n=111) and the other did not listen to BGM (n=119). The questionnaire included items assessing mood, present state of health, and demographic information like gender and age. After excluding incomplete questionnaires, 230 patients were included in our final sample for further statistical analysis. BGM was involved in decreasing feelings of fatigue and increasing feelings of vigor in patients with poorer health. This trend was more evident in female patients than in male patients. Using multiple regression analysis, we found that, in addition to BGM, environmental factors such as light level and noise level significantly affected mood. In conclusion, BGM alleviates uncomfortable moods caused by illness, particularly among females in poor health.

Recently many pharmaceutical industries aim at “academic-industrial alliances” to increase opportunities for new drug development. The form of the alliance is mainly a “center-based” one, but recently “open-type” alliance has also become popular. To promote effective collaboration between academia and industries, both parties should obtain clear understanding and support from society through compliance with the social requirement including accountability on the collaborative research and transparency on their relationship. In addition, clinical studies need to comply with the “Ethical Guideline for Clinical Research,” or Good Clinical Practice (GCP). Pharmaceutical industries anticipate seeing the deliverables of academic research, and are working on realization of utilizing them in actual medicinal cases.

Developments in the use of genetically modified plants for human and livestock health and phytoremediation were surveyed using information retrieved from Entrez PubMed, Chemical Abstracts Service, Google, congress abstracts and proceedings of related scientific societies, scientific journals, etc. Information obtained was classified into 8 categories according to the research objective and the usage of the transgenic plants as 1: nutraceuticals (functional foods), 2: oral vaccines, 3: edible curatives, 4: vaccine antigens, 5: therapeutic antibodies, 6: curatives, 7: diagnostic agents and reagents, and 8: phytoremediation. In total, 405 cases were collected from 2006 to 2010. The numbers of cases were 120 for nutraceuticals, 65 for oral vaccines, 25 for edible curatives, 36 for vaccine antigens, 36 for therapeutic antibodies, 76 for curatives, 15 for diagnostic agents and reagents, and 40 for phytoremediation (sum of each cases was 413 because some reports were related to several categories). Nutraceuticals, oral vaccines and curatives were predominant. The most frequently used edible crop was rice (51 cases), and tomato (28 cases), lettuce (22 cases), potato (18 cases), corn (15 cases) followed.

This study aimed to determine how much time can be saved with the use of unit-of-use packaging for prescription drugs as compared with bulk packaging in community pharmacies as well as to determine the number of errors. In a simulation, mock prescriptions were dispensed either in unit-of-use packages or by transferring medication from a bulk container, and a time study was conducted to measure the time spent on dispensing and prescription auditing by pharmacists. Pharmacists' and patients' degree of satisfaction was also surveyed. The time saved with unit-of-use packaging was 66.25 s per prescription. The sole dispensing error that was found in the study occurred with bulk dispensing. Among both pharmacists and patients, many were of the opinion that dispensing with unit-of-use packaging was preferable to bulk dispensing. Unit-of-use packaging shortens the time that pharmacists spend on dispensing activities and increases the efficiency of their work. Unit-of-use packaging is also thought to reduce the number of counting errors.

In Japan, information technology (IT) in the medical field has prevailed as a means for handling claims for health insurance reimbursement. In contrast, IT is primarily used for electronic medical records in Western countries. Originally, preparation of health insurance claims was one of the outcomes of computerized medical information in Japan. As its protocols are already well established in Japan, information from the insurance claim system is hard to integrate into the Electronic Medical Chart system. To ensure drug safety, it is necessary to determine the number of users, and to accurately tabulate the incidence of adverse events. For this purpose, three kinds of information are required: prescription information, dispensing information, and drug administration information. Prescription information and dispensing information should be consistent with each other in content. Dispensing information is essential to identify the “substance” when adverse events occur. Drug administration information is the “true drug history”. With these three kinds of information, it should be possible to enter drug safety data as evidence. To accurately capture these three kinds of information, it is necessary to utilize Standard Drug Code and Standard Usage Master, suggesting that it may be necessary to reconstruct the current system.

Xi-xin is a crude drug using a subterranean portion of a few plants of Asiasarum genus (Asaraceae family). The most important of its component has been reported as methyleugenol which makes up about 50% of its essential oil but this was found to vary greatly according to habitat of the plant. Some plants contained safrole, eucarvone, and 1, 8-cineol as the chief components. Xi-xin oil from Manchurian plant was proved to contain elemicin, an isomer of cis-asaron.Tu-xi-xin is the dried root of Hetehotropa genus of the same family and used as a substitute for Xi-xin. The chief component of its essential oil had been reported as safrole but elemicin was found to be present as the chief component in some of the crude drug.

Signal-transducing adaptor protein-2 (STAP-2) was recently identified as a novel adaptor protein and is a family of STAP adaptor protein and has a variety of functions in cellular signal transductions. Especially STAP-2 has a crucial role in immune systems by controlling cytokine signal transduction. STAP-2 functionally interacts with STAT3 through its YXXQ motif and enhances STAT3 transcriptional activation. In contrast, STAP-2 interacts with STAT5 through its PH and SH2-like domains and decreases STAT5 activity. Importantly, STAP-2 also binds to MyD88 and IKK-α/β and regulates LPS/TLR4 signaling. Moreover, STAP-2 interacts with Epstein-Barr virus-derived LMP1 and modulates LMP1-mediated NF-κB signaling. More importantly, experiments using STAP-2 deficient mice showed that STAP-2 modulated several T-cell functions. T-cells from STAP-2 deficient mice showed enhanced integrin-mediated cell adhesion to fibronectin. Furthermore STAP-2-deficient T-cells show reduced chemotaxis toward SDF-1α. These accumulated evidences indicate that novel adaptor protein STAP-2 plays an important modulator role in both of innate and adaptive immune systems.

The mitogen-activated protein kinase (MAPK) pathways are signal transduction mechanisms that regulate many cellular processes in eukaryotic organisms, from yeasts to mammals. Multiple MAPKs regulate eukaryotic gene expression in response to various extracellular stimuli through phosphorylation of transcription factors. We have been studying the Pmk1 MAPK, a homologue of the mammalian ERK/MAPK in fission yeast. The Pmk1 MAPK regulates cell integrity and cell morphology. We have previously demonstrated that Atf1, a transcription factor downstream of the stress-activated MAPK pathway, serves also as a target of the Pmk1 MAPK signaling in fission yeast. Here, we identified ecm33+ gene, encoding a glycosyl-phosphatidylinositol (GPI)-anchored cell surface protein as a transcriptional target of Pmk1 and Atf1. The gene expression of ecm33+ is regulated by two transcription factors Atf1 and Mbx1. We also developed an in vivo real-time monitoring system of Atf1 or Mbx1 transcriptional activity, which enables to monitor the activation of the Pmk1 MAPK pathway by various stimuli. Finally, we demonstrated that Ecm33 is involved in the negative regulation of the Pmk1 MAPK signaling through the control of Ca2+ homeostasis. The ecm33 deleted cells displayed Ca2+ sensitivity and increased phosphorylation levels of Pmk1 MAPK. In addition, the Ecm33 overproducing cells displayed phenotypes closely similar to those of the pmk1 knockout cell. Collectively, Ecm33 plays a role in the negative feedback regulation of Pmk1 cell integrity signaling.

Roundabout4 (Robo4) is a transmembrane receptor that belongs to the Robo family of neural cell adhesion molecules. Robo4 has been shown to play a role in endothelial cell (EC) migration, proliferation, angiogenesis, and stabilizing the vasculature. Robo4 is expressed specifically in ECs in the developing embryo, placenta, tumors, and normal tissues. The goal of our study is to understand the mechanism for Robo4 gene expression. In the previous study we demonstrated that EC-specific Robo4 gene expression was regulated by the 3-kb Robo4 promoter in the 5′-flanking region of the human Robo4 gene. In vitro studies demonstrated that the Robo4 promoter is activated by the transcription factors GA-binding protein (GABP) and SP1 through the ETS binding site at −119 and the 2 SP1 binding sites at −42 and −153, respectively. The functional relevance of these sites was confirmed by in vivo reporter gene assays using Hprt locus knock in mice. In addition to the regulation mechanism by transcription factors, our recent study implicated that epigenetic modification of the promoter contributes to the Robo4 gene expression. Here I will discuss the regulation mechanism of Robo4 gene expression by transcription factors and epigenetic control.

The cerebellar cortex, the brain region responsible for motor coordination and learning expresses a high density of B-type γ-aminobutyric acid receptor (GABAbR). Previous in vitro and in situ studies indicated that cerebellar GABAbR may mediate multiple forms of inhibitory and excitatory modulation of cerebellar circuits. Nevertheless, the in vivo influence of cerebellar GABAbR activation is unclear. As the first step in addressing this issue, we examined how pharmacological activation of cerebellar GABAbR modulates optokinetic reflex (OKR), an involuntary cerebellum-dependent eye movement for stabilizing the retinal image against the drift of the visual scene. We injected baclofen, a GABAbR-selective agonist, or control saline into the cerebellar flocculi of adult mice and then performed 1-h OKR measurement sessions on two consecutive days. In the day 1 session, the baclofen (5 nM)-injected mice and control mice showed similar initial OKR gains and similar training-induced increases in the OKR gain (OKR adaptation). This result suggests that GABAbR activation does not affect cerebellar computation for executing OKR and formation of short-term memory for OKR adaptation. At the beginning of the day 2 session, the baclofen (5 nM or 50 μM)-injected mice showed an OKR gain higher than that achieved in the day 1 session while the control mice did not. This result suggests that GABAbR activation may facilitate the formation of OKR adaptation-related long-term memory. These findings provide a new insight into the functional architecture of the cerebellar circuits and indicate GABAbR to be a new target of pharmacological therapy against diseases with cerebellar dysfunction.

Cosmetics are consumer products intended to contribute to increasing quality of life and designed for long-term daily use. Due to such features of cosmetics, they are required to ensure quality and safety at a high level, as well as to perform well, in response to consumers' demands. Recently, the technology associated with nanomaterials has progressed rapidly and has been applied to various products, including cosmetics. For example, nano-sized titanium dioxide has been formulated in sunscreen products in pursuit of improving its performance. As some researchers and media have expressed concerns about the safety of nanomaterials, a vague feeling of anxiety has been raised in society. In response to this concern, the Japan Cosmetic Industry Association (JCIA) has begun original research related to the safety assurance of nanomaterials formulated in cosmetics, to allow consumers to use cosmetics without such concerns. This paper describes the activities of the JCIA regarding safety research on nanomaterials, including a survey of the actual usage of nanomaterials in cosmetics, analysis of the existence of nanomaterials on the skin, and assessment of skin carcinogenicity of nano-sized titanium dioxide. It also describes the international status of safety assurance and regulation regarding nanomaterials in cosmetics.
