Daptomycin (DAP) has a completely different mechanism of action compared with conventional drugs for methicillin-resistant Staphylococcus aureus (MRSA) and is widely used as the first-line drug for treatment of dermal soft tissue infection and sepsis caused by MRSA infection in clinical practice. However, DAP has serious side effects, including renal dysfunction and rhabdomyolysis, and thus therapeutic drug monitoring of DAP is recommended. The purpose of this study was to develop an enzyme-linked immunosorbent assay (ELISA) for DAP that is simpler and more sensitive compared with existing assay methods and can be used in pharmacokinetic studies. Anti-DAP antibody was obtained by immunizing mice with an antigen conjugated with mercaptosuccinyl bovine serum albumin using N-(4-maleimidobutyryloxy) succinimide as a heterobifunctional coupling agent. Enzyme labeling of DAP with horseradish peroxidase was performed using pyromellitic dianhydride. The generated antibody and enzyme conjugate were used to develop a highly sensitive and specific ELISA for DAP in human serum. This ELISA shows a linear range of detection from 0.3 to 72.9 ng/mL, and a limit of quantification of approximately 0.3 ng/mL. The developed ELISA should be a valuable tool for pharmacokinetic studies and therapeutic drug monitoring of DAP.Pharmacists began preparing drug solutions intraoperatively for postoperative analgesia in the Department of Surgery at Chiba University Hospital from May 2014. To verify the usefulness of pharmacists preparing these drug solutions, we conducted a questionnaire survey among 51 anesthesiologists and received 44 responses (recovery rate 86.3%). Burden on the anesthesiologists was significantly reduced both temporally and mentally when the pharmacists prepared the drug solutions compared with when the anesthesiologists did (p less then 0.01). The anesthesiologists' degree of anxiety about sometimes having to prepare drug solutions alone without any confirmation was also significantly reduced when pharmacists prepared them (p less then 0.01), which implies the need for a double-check system. In addition, 88.6% of anesthesiologists said that they were reassured with preparations done by the pharmacists under a sterile environment using a clean bench. Overall, 88.6% of anesthesiologists responded that they were satisfied with the preparation of drug solutions by pharmacists. Based on the results of this survey, pharmacists' preparation of drug solutions for postoperative analgesia is considered to be useful in ensuring the quality and safety of medical care because it reduced anesthesiologists' work to prepare the drug solutions, allowing them to concentrate on anesthesia and related work, it established a double-check system between the two staff teams, and it was done under a sterile environment.With the progress of medical treatment, information on drugs, etc. is overflowing on the media and the Internet, and some of them are leading to uncertain information for the purpose of profit, and some of them are wrong information or inaccurate information, and the effect on the patient is regarded as a problem. In Japan, information on public pharmaceuticals for patients and consumers is provided on the Internet, but its utilization is not sufficient. In the Pharmaceuticals and Medical Devices Act, it is stated that "Citizens shall endeavor to use pharmaceuticals, etc., properly and deepen their knowledge and understanding of their efficacy and safety". On the other hand, there is a variety of information available on the Internet, and simply searching does not necessarily lead to reliable information. It is necessary to provide information with a mechanism to ensure that the information is reliable so that it can lead to appropriate medical care. Overseas, medical information infrastructure systems, including highly reliable public pharmaceuticals based on evidence, have been developed. Examples include National Health Service (NHS) in the United Kingdom, MedlinePlus in the United States, and National Prescribing Service (NPS) MedicineWise in Australia. In the era of digital health, it is necessary to discuss issues and prospects for the construction and dissemination of information provision infrastructure that meets the needs of patients and consumers from the perspective of industry, government, academia, and patients.Health literacy is defined as the ability to obtain, evaluate, and scrutinize health information and make appropriate decisions and actions. The spread of the Internet means that medical and drug information is becoming increasingly accessible to patients. However, there is also a large amount of inappropriate and biased medical- and drug-related information on the Internet. Therefore, patients require a high level of health literacy to ensure the effectiveness and safety of pharmacotherapy. In particular, outpatients need a high level of health literacy because they use their own medications without the supervision of healthcare professionals. In this article, I discuss the situation of health literacy and access to pharmaceutical information on the Internet in Japan. Furthermore, issues related to providing drug information to specific populations are explained using the example of chronic kidney disease. It is essential for all pharmaceutical information stakeholders to work together to solve these problems.When taking a drug one must keep in mind certain risks and benefits based on the safety and efficacy information. One of the most reliable sources of information that enables patients to use drugs properly is package inserts, which are regulated under the law and therefore should include valid and accurate contents. With the recent revision of the Pharmaceutical and Medical Device Act, the information contained in the package insert, which was provided together with the drug, will now also be provided electronically and separately from the drug itself. In addition, a digital code will be displayed on the product packaging so that the latest information of the drug can be obtained from outside the package by scanning the code. The more drug information gets shared among healthcare professionals, patients and the public, the less the asymmetry in drug information among them will exist. It is necessary now more than ever to establish a framework and a system to ensure that sufficient information is provided to patients and the public to encourage their proper use of drugs. I believe that it is important for patients and the public to strive for a better understanding of drug information. It is also crucial for all relevant parties involved in drug information to work together on how best to utilize the information. In this way they would keep trying so that therapeutic effects could be maximized and the risks of side effects are minimized.Nowadays, approximately 90 percent of the general population in Japan uses the internet and many of them look for health-related information. However, there have been serious concerns about the contents and credibility of these information. Among "mixture of wheat and chaff", information provided by the public domains are expected as accurate and reliable ones. This article reviews five public websites that provide health or health care information for users including the general population Minds by the Japan Council for Quality Health Care, e-health net, evidence-based Japanese Integrative Medicine (eJIM), Cancer Information Service by the National Cancer Center, Center for Cancer Control and Information Services, Information system on safety and effectiveness for health foods (HF net) by National Institute of Health and Nutrition. These websites show their running policy transparently and have constructed collaborative relationships with each domain experts, and from the people who are not related with the healthcare field including patients in some cases. Each of them is content-rich and well-organized as an individual unit. The organizations that run these websites share the common goal that provides the general population with quality health-related information, however, cooperation have been limited. To increase awareness among the public, it is worthy considering joint efforts of these organizations in future.Developmental retardation of the brain with reduced cortical neurogenesis is observed in Ts1Cje mice, a model of Down syndrome (DS) as it is in people with DS; however, the mechanisms and the responsible gene(s) remain unknown. The goal of the present study is to establish a therapeutic approach for treating the delayed brain development in DS. To achieve this, we have utilized multiple OMICS analyses, including proteomics and transcriptomics, to uncover the molecular alterations in the brains of DS model mice. Furthermore, we have elucidated that a transcriptional factor, the Erg gene, which is coded in the trisomic region, contributed to reduced cortical neurogenesis in the embryo of a DS mouse model by a molecular genetic technique, the "in vivo gene subtraction method". In the current review, I will introduce our recent work, the identification of the gene responsible for delayed brain development in the DS mouse model and will discuss the possibility that blood vessel dysfunction may be associated with reduced embryonic neurogenesis in DS.Microglia are immune cells resident in the central nervous system (CNS). It has been gradually clarified that microglia play various roles at the developmental stage of the CNS. From embryonic to early postnatal age, microglia remove apoptotic cells by phagocytosis and refine the neural circuits by synaptic pruning. selleck In addition, microglia promote the proliferation and differentiation of neural stem cells by releasing physiologically active substances. Our group has focused on the physiological actions of microglia via cytokines and chemokines at the early postnatal developmental stage. We found that a large number of activated microglia accumulate in the early postnatal subventricular zone (SVZ). We demonstrated that the these SVZ microglia facilitate neurogenesis and oligodendrogenesis via inflammatory cytokines including IL-1β, TNFα, IL-6, IFNγ. We have also found that microglia regulate the functional maturation of the blood brain barrier (BBB) and identified the cytokines and chemokines involved in the effects of microglia. These findings indicate that microglia are physiologically more important than ever thought to reveal robust brain functions. Furthermore, the new mode of microglial action may lead to the discovery of drug targets of the incurable CNS diseases.Folds of the cerebral cortex, which are called gyri and sulci, are one of the most prominent features of the mammalian brain. However, the mechanisms underlying the development and malformation of cortical folds are largely unknown, mainly because they are difficult to investigate in mice, whose brain do not have cortical folds. To investigate the mechanisms underlying the development and malformation of cortical folds, we developed a genetic manipulation technique for the cerebral cortex of gyrencephalic carnivore ferrets. Genes-of-interest can be expressed in the ferret cortex rapidly and efficiently. We also demonstrated that genes-of-interest can be knocked out in the ferret cortex by combining in utero electroporation and the CRISPR/Cas9 system. Using our technique, we found that fibroblast growth factor (FGF) signaling and sonic hedgehog (Shh) signaling are crucial for cortical folding. In addition, we found that FGF signaling and Shh signaling preferentially increased outer radial glial cells and the thickness of upper layers of the cerebral cortex.
