    BACKGROUND: Several genes implicated in high-density lipoprotein (HDL) metabolism have been reported to be associated with age-related macular degeneration (AMD). Furthermore, HDL transport the two carotenoids, lutein and zeaxanthin, which are highly suspected to play a key-role in the protection against AMD. The objective is to confirm the associations of HDL-related loci with AMD and to assess their associations with plasma lutein and zeaxanthin concentrations.
    METHODS: Alienor study is a prospective population-based study on nutrition and age-related eye diseases performed in 963 elderly residents of Bordeaux, France. AMD was graded according to the international classification, from non-mydriatic colour retinal photographs. Plasma lutein and zeaxanthin were determined by normal-phase high-performance liquid chromatography. The following polymorphisms were studied: rs493258 and rs10468017 (LIPC), rs3764261 (CETP), rs12678919 (LPL) and rs1883025 (ABCA1).
    RESULTS: After multivariate adjustment, the TT genotype of the LIPC rs493258 variant was significantly associated with a reduced risk for early and late AMD (OR=0.64, 95%CI: 0.41-0.99; p=0.049 and OR=0.26, 95%CI: 0.08-0.85; p=0.03, respectively), and with higher plasma zeaxanthin concentrations (p=0.03), while plasma lipids were not significantly different according to this SNP. Besides, the LPL variant was associated with early AMD (OR=0.67, 95%CI: 0.45-1.00; p=0.05) and both with plasma lipids and plasma lutein (p=0.047). Associations of LIPC rs10468017, CETP and ABCA1 polymorphisms with AMD did not reach statistical significance.
    CONCLUSION: These findings suggest that LIPC and LPL genes could both modify the risk for AMD and the metabolism of lutein and zeaxanthin.

    Fluorescence imaging of living cells provides a unique opportunity to follow dynamic behavior of specific molecules under physiological conditions. In the fission yeast Schizosaccharomyces pombe, expression of a target protein genetically fused with a fluorescent protein such as the jellyfish green fluorescent protein (GFP) is widely used. In addition, fluorescent chemical reagents are also used to stain specific molecules (e.g., Hoechst 33324 to stain DNA). Specimens of S. pombe cells for live cell imaging are prepared by either of two methods: sandwiching the cells between glass coverslips and by mounting the cells on a glass-bottom culture dish. For time-lapse observation, it is necessary to immobilize fission yeast cells on the glass surface of the glass-bottom dish because they are nonadherent and tend to move easily as a result of stage movement, convection flow of culture medium, and the contact and pushing of neighboring cells during cell growth. Either concanavalin A or soybean lectin, which bind to S. pombe cell walls, can be used for immobilization. Considerations for sample preparations and observation conditions are described.

    Summary: "This succinct, engaging text for graduate and undergraduate nursing programs distills the complexities of health care finance, economics, and policy into a highly accessible resource that can be applied to any practice setting. It presents economic and financial dynamics in healthcare as a precursor to policy and advocacy in nurses. The second edition adds graduate-level considerations and is updated to reflect our current political and legislative landscape. Real-life illustrations support foundational concepts and interactive quizzes reinforce information. Faculty resources include PowerPoint slides, a test bank, comprehensive review questions, and a sample syllabus"--Publisher's description.
