Patients' Attitudes, Awareness, and Opinions About Community Pharmacies in Japan: Next Steps for the Health Support Pharmacy System.

Purpose: Despite the formal establishment of the Health Support Pharmacy system, few community pharmacies have transitioned to this new designation in Japan. Moreover, patients' perspectives on the usefulness of health-support pharmacies and community pharmacies have not yet been investigated. In this work, we investigated patients' attitudes, opinions, and awareness as users of member pharmacies of the Japan Federation of Democratic Medical Institutions (Min-Iren), with respect to two essential functions provided by community pharmacies-primary care and health support-to identify modern challenges facing community pharmacies.

A plausible involvement of plasmalemmal voltage-dependent anion channel 1 in the neurotoxicity of 15-deoxy-Δ -prostaglandin J.

Introduction: 15-deoxy-Δ -prostaglandin J (15d-PGJ ) causes neuronal apoptosis independently of its nuclear receptor, peroxysome-proliferator activated receptor γ. Its membrane receptor, chemoattractant receptor-homologous molecule expressed on Th2 cells (CRTH2), did not also mediate the neurotoxicity of 15d-PGJ . In the present study, we ascertained whether membrane targets beside CRTH2 were involved in the neurotoxicity of 15d-PGJ .

Evaluation of molecularly imprinted polymers for chlorpromazine and bromopromazine prepared by multi-step swelling and polymerization method-The application for the determination of chlorpromazine and its metabolites in rat plasma by column-switching LC.

Monodisperse molecularly imprinted polymers (MIPs) for chlorpromazine (CPZ) and bromopromazine (BPZ), MIP and MIP, were prepared using methacrylic acid as a functional monomer and ethylene glycol dimethacrylate as a crosslinker by multi-step swelling and polymerization. The retention and molecular-recognition properties of MIP and MIP were evaluated using a mixture of potassium phosphate buffer and acetonitrile or a mixture of water and acetonitrile including ammonium formate as a mobile phase in reversed-phase LC. On MIP, CPZ, BPZ and imipramine (IMP) gave the maximal retention factors at a mobile-phase pH 8, while the maximal imprinting factors were obtained at a mobile-phase pH 7.

Function of adrenomedullin in inflammatory response of liver against LPS-induced endotoxemia.

Adrenomedullin (AM) is a hypotension-causing peptide that was originally isolated from human pheochromocytoma cells, and it has been found to be expressed in various organs, including the liver. As the individual physiological and pathophysiological properties of AM peptide in the liver during endotoxemia in vivo has not yet been examined, we investigated this in experimental endotoxemia using heterozygote AM-deficient (AM(+/-)) mice. The AM concentration of AM(+/-) mice was significantly lesser than that of wild-type (WT) mice in lipopolysaccharide (LPS)-induced endotoxemia.

Molecular mechanism of macrolide-lincosamide resistance in Moraxella catarrhalis.

We identified a Moraxella catarrhalis strain with high-level resistance to azithromycin (MIC>256 mg l(-1)), NSH1, isolated from nasopharyngeal swab samples from an inpatient with acute bronchitis in a Japanese hospital in 2011 and determined its mechanism of macrolide-lincosamide resistance. Antimicrobial susceptibility of M. catarrhalis strains was determined using the Etest and agar dilution methods.

Nutrient agar with sodium chloride supplementation for presumptive detection of Moraxella catarrhalis in clinical specimens.

We previously reported that Nissui nutrient agar (N medium) promoted the growth of Moraxella catarrhalis but not commensal Neisseria spp. In the present study, we examined which constituent of N medium was responsible for the selective growth of M. catarrhalis using 209 M.

Involvement of the mevalonate pathway in the antiproliferative effect of zoledronate on ACHN renal cell carcinoma cells.

Renal cell carcinoma (RCC) has been shown to be resistant to chemotherapy and radiotherapy. In order to examine the potential of zoledronate (ZOL), a bisphosphonate, as an anticancer agent, we investigated the effects of ZOL on RCC cells and the involvement of the mevalonate pathway in antiproliferative effects, as well as the effects of ZOL administration on mice inoculated with RCC. ACHN cells were used and cell viability was measured via intra-cellular reductase activity.
