OCNSのがんゲノム医療への関与

The purpose of this study was to clarify the current status of oncology certified nurse specialist（OCNS） involvement in cancer genome medicine. A survey of 235 OCNSs who consented to participate in the study revealed that those involved in cancer genome medicine had a better understanding of hereditary tumors. Through descriptive content analysis, 8 learning needs were identified in relation to cancer genome medicine. Among these needs,［ basic knowledge of hereditary tumors and cancer genome medicine］, ［regular acquisition of up-to-date information on genetic medicine］, and［ genetic counseling in actual clinical settings］revealed no differences between OCNSs involved and not involved in genetic medicine. On the other hand,［ role of an OCNS in genetic medicine］, ［nursing care for patients and families with hereditary diseases］, ［systems and collaboration to incorporate genetic medicine into organizations］, ［information on genetic medicine for facilities other than urban/designated hospitals］, and［ programmed learning as a systematic approach to genetic medicine provided by academic societies］ differed between the groups in terms of descriptive contents

pH-Responsive Aqueous Bubbles Stabilized With Polymer Particles Carrying Poly(4-vinylpyridine) Colloidal Stabilizer

Free radical dispersion polymerization was conducted to synthesize near-monodispersed, micrometer-sized polystyrene (PS) particles carrying pH-responsive poly(4-vinylpyridine) (P4VP) colloidal stabilizer (P4VP-PS particles). The P4VP-PS particles were extensively characterized in terms of morphology, size, size distribution, chemical composition, surface chemistry, and pH-response using optical and scanning electron microscopies, elemental microanalysis, X-ray photoelectron spectroscopy, laser diffraction particle size analysis, and zeta potential measurement. The P4VP-PS particles can work as a pH-responsive stabilizer of aqueous bubbles by adsorption at the air-water interface. At and above pH 4.0, where the particles have partially protonated/non-protonated P4VP stabilizer with relatively hydrophobic character, particle-stabilized bubbles were formed. Optical and scanning electron microscopy studies confirmed that the P4VP-PS particles were adsorbed at the air-water interface of the bubbles in aqueous media. At and below pH 3.0, where the particles have cationic P4VP stabilizer with water-soluble character, no bubble was formed. Rapid disruption of the bubbles can be induced by decreasing the pH; the addition of acid caused the in situ protonation of pyridine groups in P4VP, which impart water-soluble character to the P4VP stabilizer, and the P4VP-PS particles were desorbed from the air-water interface. The bubble stabilization/destabilization cycles could be repeated at least five times
