[Assessment of Chemotherapy-Induced Adverse Events Using a Sharing System of Patient-Reported Information via a Touch Panel].

Screening for total pain and sharing of patient information including adverse events for patients receiving chemotherapy by medical staff is needed in clinical practice. We introduced a sharing system for patient-oriented outcome sheets via a touch panel at an outpatient chemotherapy clinic. This study aimed to assess whether the system contributes to the improved management of treatment-related adverse events.

Liquid Formulation of Gemcitabine Increases Venous Pain in Patients With Cancer: A Retrospective Study.

Purpose: Venous pain induced by peripheral intravenous infusion of gemcitabine has remained an unresolved issue in clinical practice. This study aimed to identify differences between gemcitabine formulations as well as risk factors associated with gemcitabine-induced venous pain in patients with cancer.

Methods: We retrospectively analyzed data from consecutive patients with cancer who had received chemotherapy including a lyophilized or liquid formulation of gemcitabine diluted with 5% glucose solution via a peripheral vein.

Characterization of certified reference material for the quantification of water in bioethanol.

The National Metrology Institute of Japan has issued a certified reference material of bioethanol (NMIJ CRM 8301-a) for the quantification of water, methanol, sulfur, and copper. This paper presents technical details for the characterization of the water in NMIJ CRM 8301-a. The characterization was performed using coulometric and volumetric Karl-Fischer (KF) titrations.

Development of certified reference material for quantification of two pesticides in brown rice.

Brown rice powder certified reference material, NMIJ CRM 7504-a, for the analysis of pesticide residues was developed by the National Metrology Institute of Japan, part of the National Institute of Advanced Industrial Science and Technology. Brown rice sample was harvested to contain the pesticides such as etofenprox and fenitrothion, and that was collected from a field in Ibaraki Prefecture in Japan. The certification was carried out using multiple analytical methods such as pressurized liquid extraction, homogenization, and solid-liquid extraction (shaking); the values of target pesticides were obtained by isotope dilution mass spectrometry.

Preparation of a sulfoxide group and ammonium-salt bonded silica stationary phase for separation of polychlorinated biphenyls from mineral oils.

In this study, a silica stationary phase modified with sulfoxide group and ammonium-salt was prepared for the separation of polychlorinated biphenyls (PCBs) from mineral oils, and its properties were investigated. Organic sulfide was attached to a diamino (primary and secondary amino) bonded silica surface by an amide bond, and the bonded sulfide groups were oxidized with periodate to afford sulfoxide groups bonded to the stationary phase. The secondary amino groups in the spacer chain were converted to ammonium-salt by the addition of hydrochloric acid.

Differences in the yields of polycyclic aromatic hydrocarbons by pressurized liquid extraction and the Japanese official method.

To improve the extraction of polycyclic aromatic hydrocarbons (PAHs) from sediment samples, we optimized the conditions of pressurized liquid extraction (PLE). The yields increased as the extraction temperature increased from 100 to 190 degrees C, but the effect of increasing pressure (from 15 to 20 MPa) was small. Parameters of 190 degrees C and 20 MPa, near the maximum of the equipment, gave the highest yield.

Evaluation of pressurized liquid extraction for the analysis of four pesticides in unpolished rice.

The aim of to evaluate efficiency of this study was extraction pressurized liquid extraction (PLE) for the analysis of four pesticides, fthalide, etofenprox, fenitrothion, and isoprothiolane, in unpolished rice by comparing with homogenization as a reference technique. The concentrations of four selected pesticides obtained by PLE with acetonitrile at 130 degrees C for 10 min x 2 cycles were comparable to those by homogenization with water-soaking. The repeatability of the analysis, represented as relative standard deviations (RSDs), were 1.

2-Substituted-16-ene-22-thia-1alpha,25-dihydroxy-26,27-dimethyl-19-norvitamin D3 analogs: Synthesis, biological evaluation, and crystal structure.

Recently, we have found that 16-ene-22-thia-26,27-dimethyl-19-norvitamin D(3) analogs 1a (n=2, 3) are 20 times more active than the natural hormone 1alpha,25-dihydroxyvitamin D(3) in terms of transcriptional activity. To further investigate the effects of the A-ring modification of 1a, b on the biological activity profile, novel 22-thia-19-norvitamin D analogs 2-11 bearing a hydroxyethoxy-, hydroxyethylidene- or methyl group at C-2 in combination with 20S- and 20R-isomers were prepared and tested for their in vitro biological activities. All of the synthesized analogs showed 0.

Mineral oil certified reference materials for the determination of polychlorinated biphenyls from the National Metrology Institute of Japan (NMIJ).

Four mineral oil certified reference materials (CRMs), NMIJ CRM 7902-a, CRM 7903-a, CRM 7904-a, and CRM 7905-a, have been issued by the National Metrology Institute of Japan, which is part of the National Institute of Advanced Industrial Science and Technology (NMIJ/AIST), for the determination of polychlorinated biphenyls (PCBs). The raw materials for the CRMs were an insulation oil (CRM 7902-a and CRM 7903-a) and a fuel oil (CRM7904-a and CRM 7905-a). A solution of PCB3, PCB8, and technical PCB products, comprising four types of Kaneclor, was added to the oil matrices.
