The current supply of acceptable donor livers is not sufficient to meet the demands of listed patients awaiting transplantation resulting in thousands of deaths each year. Increased utilization of marginal livers may help alleviate this supply/demand mismatch by expanding the donor liver pool. The current status of liver transplantation using marginal donor grafts and efforts to optimize usage are discussed with attention to elderly donors, steatotic livers, donors after circulatory death, and s

The influence of different solvents on the individualization of single-walled carbon nanotubes (SWNTs) was investigated by several methods. A stable solution of individual SWNTs in o-dichlorobenzene was obtained by a combination of ultrasonication and ultracentrifugation. Atomic force microscopy height analysis confirmed that the final supernatant solution contained 85 % of individual tubes with a diameter equal to or less than 1.5 nm, which is consistent with the average diameter of arc-dischar

Lining up: Highly symmetrically arranged ZnO nanowire arrays (see image) are produced by laser-interference lithography and a chemical vapor transport process. The nanowires show a narrow diameter distribution and uniform spacing. A liquid-phase-assisted vapor–solid mechanism is proposed for one-to-one synthesized ZnO-nanowire growth. Scanning cathodoluminescence and photoluminescence microscopy are used to characterize the optical properties. Supporting information for this article is available

A simple and facile method has been developed that allows water-soluble hybrid materials of Au nanoparticles and hole-doped single-walled carbon nanotubes (SWNTs) to be prepared. Uniformly arranged Au nanoparticles (see TEM image) were obtained by the addition of metal salts to surfactant-suspended SWNTs in water using the solution-phase dispersion technique.

Early initiation of alcohol drinking, cigarette smoking, and sexual intercourse, particularly among preteens, represented an important predictor of later suicidal ideation and suicide attempts in both genders. Thus, early preventive intervention programs should be developed and may reduce the potential risks for subsequent suicidal behaviors.

This study suggests that BWP represents a potential mediator between BMI and UWCB, and between BMI and suicidal ideation among both boys and girls. Thus, school programs addressing issues related to BWP should be developed and targeted at adolescents to reduce the potential risks for both UWCB and suicidal behavior.
