Tests on physiological functions of umami have been actively conducted and a need recognized for a high-performance quantification device that is simple and cost-effective, and whose use is not limited to a particular location or user. To address this need, Ajinomoto Co. and Tanita Corp. have jointly been researching and developing a simple device for glutamate measurement. The device uses L-glutamate oxidase immobilized on a hydrogen peroxide electrode. L-glutamate in the sample is converted to α-ketoglutaric acid, which produces hydrogen peroxide. Subsequently, the electrical current from the electrochemical reaction of hydrogen peroxide is measured to determine the L-glutamate concentration. In order to evaluate its basic performance, we used this device to measure the concentration of L-glutamate standard solutions. In a concentration range of 0-1.0%, the difference from the theoretical value was minimal. The coefficient of variation (CV) value of 3 measurements was 4% or less. This shows that the device has a reasonable level of precision and accuracy. The device was also used in trial measurements of L-glutamate concentrations in food. There was a good correlation between the results obtained using the developed device and those obtained with an amino acid analyzer; the correlation coefficient was R=0.997 (n=24). In this review, we demonstrate the use of our device to measure the glutamate concentration in miso soup served daily at a home for elderly people, and other foods and ingredients.

In today’s world, where clinical options are ever increasing and patients’ needs are more diverse, it is not possible to conclude that simply practicing medical care based on pathophysiological data and medical evidence is sufficient for patients, particularly in terms of seeing each patient as an individual. Medical professionals must maintain a close relationship with their patients and seek treatment and care methods that reflect the patient’s values and views on life and death, based on their own ethics in medical care. Ethics education should be provided on a continuing basis from the beginning of medical/pharmacy school. However, ethics education in pharmacy departments is often delivered in a lecture format attended by many students and/or as group training using case studies and hypothetical situations, i.e., “paper” patients. With these teaching methods, there are limited opportunities for the students to foster a sense of ethics or to think deeply about their values and views on life and death with respect to the patients they care for. Therefore, in this study, we conducted ethics exercises for pharmacy students in a group study format using a documentary film of real patients who were facing death. By retrospectively analyzing the results of the questionnaires collected before and after the assignments and exercises, we verified the educational effects and changes in the students’ sense of ethics from participating in the group learning exercise; moreover, our results revealed the insight gained by the students in examining the experiences and challenges faced by terminally ill patients.

Community pharmacists in Japan participate in many important clinical cases involving drug therapies. This involvement should be researched and widely publicized to promote evidence-based medicine (EBM). However, the awareness level about the establishment of clinical evidence among community pharmacists remains unknown. Therefore, this large-scale questionnaire survey was conducted among members of the Okayama Pharmaceutical Association to clarify the awareness about the establishment of clinical evidence among community pharmacists to determine the major factors affecting their awareness. Questionnaires requiring open-ended responses were developed in Google Forms. Finally, 366 valid answers were obtained and statistically analyzed based on three aspects: academic conference presentation, research article publication, and research conduct. More than 50% of the participants agreed that they must engage in the establishment of clinical evidence. However, they were unwilling to engage in it by themselves. Additionally, the awareness about the establishment of clinical evidence among participants aged <40 years, who underwent a 6-year course, and with presentation experience was greater than that among participants aged ≥40 years, who underwent a 4-year course and without presentation experience. Thus, age, course duration, and presentation experience are important factors influencing awareness about the establishment of clinical evidence. Further, >70% of the participants did not have enough time to engage in the establishment of clinical evidence, suggesting that reducing workload and ensuring adequate time are necessary for such engagements. Our novel findings may increase the establishment of clinical evidence by community pharmacists, improve community pharmacists’ social standing, and promote EBM in Japan.

In recent years, lifestyle-related diseases such as hypertension and diabetes have been on the rise. These conditions can cause serious conditions such as myocardial and cerebral infarctions. Therefore, proper control of blood pressure and blood glucose levels is important issues in preventive medicine. Traditional fermented foods have been shown to have various functions, and their effects on lifestyle-related diseases have attracted particular attention. In this study, we investigated the effects of fermented soybeans and rice bran (OE-1) and supplements containing OE-1 on blood glucose levels and weight changes. We identified an inhibitory effect on elevated blood glucose levels upon administration of OE-1, and this effect was thought to be due to digestive enzyme inhibition. These effects of foods containing OE-1 are expected to have a positive effect on the prevention and improvement of lifestyle-related diseases as health foods.

Using the usual tabletting machine used in the factory and without changing the amount of granules supplied, two kinds of granules were submitted to tabletting at a constant tabletting speed, the same mortar volume, and in three positions of the upper pounder (giving three different thicknesses of tablet), and correlation between the forming pressure measured and various characters of the products was examined. From such results, following points were clarified:1) Naturally, there was no relation between pressure and weight of the tablet but differentiation by the position of the upper pounder (thickness of tablets) showed that there existed a positive correlation within each stratum. Appearance of such correlation in the case of one of the granules was found to be the interference of the change in the amount of granules supplied into the factor of the position of the upper pounder.2) There is a negative correlation between pressure and thickness but differentiation by the thickness indicated the presence of a positive correlation. This indicates that there is a positive correlation between weight and thickness.3) There is positive correlation between pressure and the quotient of weight by thickness.4) There is a positive correlation between pressure and compressive strength.5) Within the conditions used in the present experiments, no difference was found in the results from two kinds of granules.

A strain of hyphomycetes that produces a toxic substance was isolated from a fungus that was parasitically growing on the malt feed responsible for mass death of milking cows. The fungus penetrates into malt grains from an injured section, causes morbid change in the starch and aleuron layers, to brown the tissues, and produces a metabolic products that causes marked toxicity in animals. The fungus was found to grow on a medium with a wide variety of carbon source. The morphology of the fungus on the Czapek culture medium is as follows: Vegetative mycelium, 3-5×18μ; aerial mycelium, 2μ diam.; conidiophore, 3.0-4.5×400-500μ; metulae, 3.0-5.2×6.0-10.4μ; sterigmata, 2.3-2.7×6.0-6.7μ; conidia, 2.5×3.2μ. Since the morphology and other properties of this fungus are identical with the description for Penicillium urticae Bainier in the classification by Thom (“A Manual of the Penicillia” (1949)), the fungus is now determined as that strain.

β2-Adrenergic agonists have been widely used to treat patients with asthma. Usually, oral dosage forms of β2-agonists have been used, but side effects such as palpitation and tremor have been reported because of excessive serum levels around Tmax. It is said that circadian variations exist in the manifestation of asthma with maximum incidence of asthma attacks in early morning at around 4 a.m., the so-called morning dip. Chronotherapy for asthma based on circadian rhythm should be more efficient and have a lower frequency of side effects. Accordingly we developed a transdermal delivery system of the β2-agonist tulobuterol adapted to the circadian rhythm. The system is designed to administer the appropriate dose of the drug at an optimal time using the so-called Crystal Reservoir System. The superiority of the transdermal formulation of tulobuterol over the current therapy using oral formulations of β2-stimulants was indicated by its excellent pharmacokinetic profile, and confirmed by the results of clinical trials. This formulation is the first transdermal chrono-delivery system reported anywhere in the world, and is expected to provide more effective and safe treatment of asthma and related diseases not only in adults, but also especially in children.

Attempt was made to obtain homogeneous vitamin B1 tablets by the improvement of manufacturing processes from finding the cause of variations in content of vitamin B1. As a result it was experimentally confirmed that the following equation is establishedσr2=σw2+σc2+σm2+2ρ⋅σw⋅σcwhen σr, σω, σc and σw respectively stand for the observed value, weight, content per unit weight, and standard deviation of determined value, and ρ, the coefficient of interdependence. From these findings, improvements were made on the mixing and granulation processes. Examinations were also made on the thiochrome process for determination of vitamin B1, conditions for direct absorption determination, and interdependence.

This paper introduces the research of nanomachines utilizing boron chemistry. Boron neutron capture therapy (BNCT) has beeing attracting increasing attention as a minimally invasive cancer treatment, and p-boronophenylalanine (BPA) has been approved as a potent BNCT drug. However, intratumoral retention of BPA remains to be improved. Recently, we have developed a BPA delivery system [poly vinyl alcohol (PVA)–BPA] utilizing PVA. PVA–BPA altered the uptake pathway of BPA by cancer cells and significantly improved the intracellular retention in cancer cells. in the in vivo experiments, PVA–BPA showed improved tumor accumulation and a remarkable tumor growth inhibition upon thermal neutron irradiation. On the other hand, a useful delivery system of bioactive proteins has been strongly demanded. In this study, we have developed the ternary complex micelles for the protein delivery utilizing tannic acid (TA) and block copolymer containing a boronic acid group. The ternary micelles improved the blood retention and tumor accumulation of the loaded proteins, and realized a tumor tissue-selective enzymatic reaction in the enzyme delivery.

The proteolytic enzyme inhibitor nafamostat mesylate is widely used for the treatment of acute pancreatitis and disseminated intravascular coagulation. This drug may be a risk factor for phlebitis, but this risk has not been studied. Therefore, we aimed to investigate the frequency of phlebitis and its risk factors in patients treated with nafamostat mesylate in intensive care units (ICU) or high care units (HCU). During the study period, 83 patients met the inclusion criteria, and 22 of them (27%) experienced phlebitis. A multivariate logistic regression analysis was performed for severe acute pancreatitis, administration duration, and administration concentration of nafamostat mesylate in the ICU or HCU. As a result, the administration of nafamostat mesylate for ≥ 3 days in the ICU or HCU was an independent predictor of phlebitis caused by nafamostat mesylate (odds ratio, 10.3; 95% confidence interval, 1.28–82.5; p=0.03). This study suggests that the number of days of nafamostat mesylate administration is associated with phlebitis in patients treated with the drug, and it may be necessary to pay attention to its administration for ≥ 3 days in the ICU or HCU.

Molecular simulations have been widely used in biomolecular systems such as proteins, DNA, etc. The search for stable conformations of proteins by molecular simulations is important to understand the function and stability of proteins. However, finding the stable state by conformational search is difficult, because the energy landscape of the system is characterized by many local minima separated by high energy barriers. In order to overcome this difficulty, various sampling and optimization methods for the conformation of proteins have been proposed. In this study, we propose a new conformational search method for proteins based on a genetic algorithm. We applied this method to an α-helical protein. We found that the conformations obtained from our simulations are in good agreement with the experimental results.

Vitamin K plays an important role in blood coagulation and bone formation. However, apart from the liver and bone, the role of vitamin K in other tissues remains unknown. Previously, we have reported on high concentrations of vitamin K in the mouse brain and investigated vitamin K conversion in brain tissue. This led us to hypothesised the possibility of vitamin K contributing significantly towards maintenance and function of the cranial nervous system. In this review, we summarise the synthesis of novel vitamin K derivatives, their neuronal differentiation inducing activities and the induction mechanism. The findings from this study will provide insights into the physiological roles of vitamin K in the brain.

Gyokuheifusan (GHS, Jade Windscreen Powder in English, Yupingfengsan in Chinese) is an herbal formula in traditional Kampo medicine which consolidates superficial resistance to protect against invasion by external pathogens. This review describes the immunopharmacologic properties of GHS as a holistic Kampo medicine, which can affect human homeostasis and constitution of human beings. Oral treatment with GHS has preventive and curative effects in allergic rhinitis induced by Japanese cedar pollen in guinea pigs. Since these effects do not occur with authentic antiallergic agents, GHS appears to have holistic effects on allergic rhinitis. In another study, the effects of GHS on murine antibody production against ovalbumin (OVA) were evaluated. When mice were sensitized intraperitoneally to OVA, the concentration of OVA-specific immunoglobulins in the sera significantly increased with GHS treatment. When they were sensitized intranasally to OVA, GHS significantly reduced the concentration of OVA-specific antibodies in the sera. It was suggested that GHS stimulats immune responses when the antigen had already invaded the body, and that GHS might consolidate the resistance of nasal mucosa to protect from OVA invasion, and then OVA-specific antibodies in sera might be suppressed. These results suggest that traditional medicines have own characteristics different from those of modern medicines, and that original pharmacologic experiments are important to evaluate traditional medicines scientifically.

Warfarin (WF) shows a number of interactions with other drugs, which alter its anticoagulant effects. The albumin binding interaction is one such pharmacokinetic mechanism of drug interaction with WF, which induces a rise in the free WF concentration and thus increases the risk of WF toxicity. Teicoplanin (TEIC) is an anti-methicillin-resistant Staphylococcus aureus drug, which also binds strongly to albumin in the plasma. Therefore, co-administration of TEIC may displace WF from the albumin binding site, and possibly result in a toxicity. The present study was performed to investigate the drug-drug interaction between WF and TEIC in comparison with controls treated with vancomycin (VCM), which has the same spectrum of activity as TEIC but a lower albumin binding ratio.The records of 49 patients treated with WF and TEIC or VCM at Fukuoka University Hospital between 2010 and 2015 were retrospectively reviewed. These 49 patients consisted of 18 treated with TEIC in combination with WF, while 31 received VCM in combination with WF. Prothrombin time-international normalized ratio (PT-INR) showed a significant increase of 80.9 (52.0-155.3) % after co-administration of TEIC with WF. In contrast, the rate of PT-INR elevation associated with VCM plus WF was 30.6 (4.5-44.1) %. These observations suggested that TEIC can cause a rise in free WF concentration by albumin binding interaction. Therefore, careful monitoring of PT-INR elevation is necessary in patients receiving WF plus TEIC.

Daphne genkwa (Thymelaeaceae) has been used as a folk medicine in China. We investigated the effects of D. genkwa and Jyu-So-To on various pharmacologic models in mice including the azoxymethane (AOM)-induced colonic aberrant crypt focus formation assay, ornithine decarboxylase (ODC) activity assay, and two types of mouse ear swelling model. Administration of 236.3 ppm of Jyu-So-To in drinking water significantly suppressed AOM-induced colonic aberrant crypt focus formation (p < 0.05), with an inhibitory ratio of 46.7%. The effects of several extracts with organic solvents of D. genkwa on murine epidermal ODC activity were examined. In particular, the inhibitory ratio of the n-hexane extract was 30.8%. In the 12-O-Tetradecanoylphorbol-13-acetate (TPA)-induced ear edema model in mice, the methanol extract resulted in 56.3% inhibition compared with the control. On the other hand, there are two peaks of responses at 1 h (immediate-phase reaction; IPR) and 24 h (late-phase reaction) in biphasic cutaneous reactions, which are enhanced in the dinitrofluorobenzene model (DNFB). The water extract of D. genkwa clearly inhibited the IPR ear swelling. These results suggest that D. genkwa and Jyu-So-To should be a promising source of antitumor, antiinflammatory, and antiallergy agents.

The effects of drugs and other low-molecular-weight compounds are complex and may be unintended by the developer. These compounds and drugs should be avoided if these unintended effects are harmful; however, unintended effects are not always as harmful as suggested by drug repositioning. Therefore, a comprehensive understanding of complex drug actions is essential. Omics data can be regarded as the nonarbitrary transformation of biological information about a sample into comprehensive numerical information comprising multivariate data with a large number of variables. However, the changes are often based on a small number of elements in different dimensions (i.e., latent variables). The omics data of compound-treated samples comprehensively capture the complex effects of compounds, including their unrecognized aspects. Therefore, finding latent variables in these data is expected to contribute to the understanding of multiple effects. In particular, it can be interpreted as decomposing multiple effects into a smaller number of easily understandable effects. Although latent variable models of omics data have been used to understand the mechanisms of diseases, no approach has considered the multiple effects of compounds and their decomposition. Therefore, we propose to decompose and understand the multiple effects of low-molecular-weight compounds without arbitrariness and have been developing analytical methods and verifying their usefulness. In particular, we focused on classical factor analysis among latent variable models and have been examining the biological validity of the estimates obtained under linear assumptions.

Liposomes modified with polyethylene glycol (PEG) can stably exist in the bloodstream because the PEG on the liposomes attracts a water shell to the liposomal surface. Since these liposomes are long circulating nanocarriers, they are used as drug and gene delivery tools. Repeat injection of PEGylated liposomes, however, is known to induce the accelerated blood clearance (ABC) phenomenon. In the ABC phenomenon, PEGylated liposomes that are injected subsequent to the first injection are cleared rapidly from the bloodstream and accumulate in the liver, resulting in loss of their long-circulating characteristics. The induction of ABC phenomenon is related to the production of anti-PEG IgM from splenic B cells. To elucidate the mechanism of the phenomenon, we firstly examined the relationship between the induction of ABC phenomenon and the concentration of PEGylated liposomes, and observed that the high dose of those did not induce the phenomenon. Next, we investigated whether polymeric micelles trigger ABC phenomenon or not. Finally, the size-dependency of ABC phenomenon was investigated by use of variously sized PEGylated liposomes and polymeric micelles having PEG chains. Our data suggest that the initiation of ABC phenomenon would be size-dependent, and particles smaller than 30 nm did not induce ABC phenomenon. We anticipate that the elucidation of the ABC phenomenon will be helpful for the development of DDS formulations.

A 55-year-old man with hypertrophic cardiomyopathy and a pacemaker was admitted with coronavirus disease 2019 (COVID-19). Before admission, the patient's medications included amiodarone, diltiazem, bisoprolol, atorvastatin, etizolam, and warfarin (WF). After admission, dexamethasone (DXM) and remdesivir (RDV) were initiated for treating COVID-19. The international normalized ratio (INR) on admission was 1.8, which increased to 3.4 on day 5 and to 6.9 on day 10 after admission. Although there have been reports that RDV may occasionally prolong prothrombin time and that the degree of prolongation is often less severe, the mechanism of action has not been elucidated till date. There are reports of prolonged INR when WF is co-administered with RDV and DXM, suggesting that drug interactions may be a potential cause for the prolongation. A similar drug interaction may have potentially occurred in the case reported here. In addition, this case used amiodarone (AMD), and it has been reported that the RDV concentration increases when used in combination with AMD. Further investigations are needed to elucidate the cause of INR prolongation. Thus, close monitoring of the patient is recommended when RDV is co-administered with high-risk agents to avoid unnecessary side effects.

Central neural circuits in the brain receive and integrate environmental and internal information to enable the animals to execute appropriate behaviors and physiological responses. Communication between the brain and peripheral organs via peripheral neural circuits maintains energy homeostasis in the body. Therefore it is important to investigate the anatomical organization of central and peripheral neural circuits for elucidating the mechanisms of energy homeostasis. Transsynaptic viral tracers can travel through connected neurons via synaptic connections and have been used to delineate the anatomical organization of neural circuits with specific functions. Herein, I review our recent studies investigating neural circuits and their involvement in physiological changes using transsynaptic tracers.
