AIMTo develop a rapid and sensitive method for monosaccharide composition analysis.
METHODSGlycoprotein was first hydrolyzed to monosaccharides, which were subsequently reacetylated (amino monosaccharides), tagged with 2-aminopyridine and then separated and monitored in selected ion mode by CapGCC-LC/MS. The use of tetradeuterium labeled-aminopyridyl-monosaccharides prepared by tagging monosacahrides with hexadeuterium labeled 2-aminopyridine as internal standards improved the linearity and reproducibility in quantification.
RESULTSThis method was successfully applied to monosaccharide composition analysis of model glycoproteins, fetuin and erythropoietin down to 1 pmol monosaccharides.
CONCLUSIONThis method has been shown to be highly sensitive and is applicable to monosaccharide composition analysis of glycoproteins.

The core curriculum of the pharmacy education model was revised in 2013 based on the “Basic competencies required of a pharmacist” that should be developed by graduation. Specific behavioral objectives to acquire include competency in “The ability to implement pharmacotherapeutic management”, which involves gaining the ability to understand patient information, prescription design and proposal, as well as pharmacotherapeutic assessment. In order to improve this ability, it is necessary for students to acquire basic knowledge about pathology, pharmacology, and pharmacotherapy and to integrate and apply this knowledge to patients in practice. We introduced an integrated program called “Integrated Clinical Pharmacy” for fifth-year students at Hokkaido Pharmaceutical University. In this program, students take an objective test on the basic knowledge of pathology, pharmacology, and pharmacotherapy and learn how to design pharmaceutical care plans using individual patient cases. A self-evaluation questionnaire survey about the ability to develop care plan was conducted on students who completed the program. Based on the objective test and self-evaluation questionnaire results, we studied whether basic knowledge was fully established and whether the ability to utilize this knowledge was acquired through this program. We found that although the ability to select an individual component of care plan did improve, this ability wasn’t correlated with the degree of basic knowledge, and performance in summarizing care plan did not improve. These results suggested that it is necessary to understand the connection between components of the care plan and strategies to focus on improving the ability to integrate basic knowledge.

Purpose In a series of our recent studies, systematic mild hyperthermia treatments, such as sauna, hot spring and a special bath for medical treatment, were found to activate leucocytes and to enhance immunity. Although they are known to be effective for health promotion, it is not easy for general people to regularly take these conventional hyperthermia. It would be advantageous for elderly persons, sick people and pregnant women as well as pressed business persons if it is able to minimize stress which might be induced by the conventional hyperthermia, such as high temperature heat, water pressure and humidity. To pursue a further study of the effect of hyperthermia itself, in this research, we utilized nano-mist sauna (NMS), a new hyperthermia treatment. NMS, a new type sauna, is characterized by the ability to produce ultra small fog-shaped hot water called nano-mist, which hardly condenses dew. And we studied the effect of NMS on body temperature, leukocytes, autonomic nerve function and energy production. Method We obtained peripheral blood from six healthy male volunteers (age, 46.5±8.5 years) before and after NMS hyperthermia (20min, 40°C, 100%RH) for lactate and blood glucose measurement and flowcytometric analysis. Body temperature (hypoglossal) and pulse rates were also measured. The statistical analysis difference between the values was determined by paired t-test and Kruskal-Wallis test. Result After NMS hyperthermia body temperature and the level of PO2 rose (36.8→37.2°C), (52→61mmHg) (p<0.05). On the other hand, the level of lactate showed decrease in all subjects. The ratio and the numbers of NK cells decreased (21.8→17.7%, 498→436/μL) (p<0.05) while those of B cells increased (9.5→12.1%, 261→349/μL) (p<0.05). Discussion Several investigators report that the conventional hyperthermia enhances the primordial immune system (i.e. extrathymic T cells, NK cells, NKT cells and granulocytes) via dominance of sympathetic nerve system function (SNS) . Conversely, in our study, those of the conventional immune system (i.e. T and B cells) was enhanced, suggesting suppression of SNS function. It is reported that the expression level of HLA-DR on the B cells was elevated during hyperthermia (body temperature rose). SNS function (hypothermia) is stimulated by stress and it is suppressed by relaxing (hyperthermia) in the opposite. And it is considered that NMS hyperthermia suppressed SNS and that it was also consistent with our result of lactate decrease. It is possible to consider that NMS hyperthermia may impact on autonomic nerve activating leucocytes. Therefore NMS may be a kind of effective health promotion for valetudinarian (ie an infant, a female) and both a caregiver and a caretaker.

Objective:
Recently, rational polypharmacy approaches have been proposed, regardless of the lower risk and cost of monotherapy. Considering monotherapy as first-line treatment and polypharmacy as rational treatment, a balanced attitude toward polypharmacy is recommended. However, the high prevalence of polypharmacy led the Japanese government to establish a polypharmacy reduction policy. Based on this, the association between the policy and psychiatrists’ attitude toward polypharmacy has been under debate.
Methods:
We developed an original questionnaire about Psychiatrists’ attitudes toward polypharmacy (PAP). We compared the PAP scores with the treatment decision-making in clinical case vignettes. Multiple regression analyses were performed to quantify associations of explanatory variables including policy factors and PAP scores. The anonymous questionnaires were administered to psychiatrists worldwide.
Results:
The study included 347 psychiatrists from 34 countries. Decision-making toward polypharmacy was associated with high PAP scores. Multiple regression analysis revealed that low PAP scores were associated with the policy factor (β=-0.20, p=0.004). The culture in Korea was associated with high PAP scores (β=0.34, p<0.001), whereas the culture in India and Nepal were associated with low scores (β=-0.15, p=0.01, and β=-0.17, p=0.006, respectively).
Conclusion
Policy on polypharmacy may influence psychiatrists’ decision-making. Thus, policies considering rational polypharmacy should be established.
