“To date, no study has characterized the association between neighborhood poverty, racial composition and deceased donor kidney waitlist. Using the United States Renal Data System data linked to 2000 U.S. Census Data, we examined Whites (n = 152 788) and Blacks (n = 130 300) initiating dialysis between January 2000 and December 2006. Subjects’ neighborhoods were divided into nine strata based on the percent of Black residents and percent poverty. Cox proportional

hazards were used to determine the association between time to waitlist and neighborhood characteristics after adjusting for demographics and comorbid conditions. Individuals from poorer neighborhoods had a consistently lower likelihood of being waitlisted. This association was synergistic with neighborhood racial composition for Blacks,

SN-38 solubility dmso but not for Whites. Blacks in poor, predominantly Black neighborhoods (adjusted hazard ratio [HR] 0.57, Nirogacestat price 95% confidence intervals [CI] 0.53-0.62) were less likely to appear on transplant waitlist than those in wealthy, predominantly Black neighborhoods (HR 0.80, CI 0.67-0.96) and poor, predominantly White neighborhoods (HR 0.79, CI 0.70-0.89). All were all less likely to be waitlisted than their Black counterparts in wealthy, predominantly White or mixed neighborhoods (p < 0.05). Interventions targeted at individuals in poor and minority neighborhoods may represent an opportunity to improve equitable access to the deceased donor kidney waitlist.”
“Micron scale ferromagnetic tubes placed on the ends of ferromagnetic CoTaZr spin waveguides are explored in order to enhance the excitation of backward volume magnetostatic spin waves. The tubes produce a closed magnetic circuit about the signal line of the coplanar waveguide find more and are, at the same time, magnetically contiguous with the spin waveguide. This results in a ten-fold increase in spin wave amplitude. However, the tube geometry distorts the magnetic field near the

spin waveguide, and relatively high biasing magnetic fields are required to establish well-defined spin waves. Only the lowest (uniform) spin wave mode is excited. (C) 2011 American Institute of Physics. [doi: 10.1063/1.3559475]“
“The synthesis of tetrakis- derivatives of bisphenol-A containing azo groups at their 2,2′,6,6′-positions is reported. Novel examples of bisphenol-A, coupled with diazonium salts and derived from 4-phenylazoaniline and 5-(4-aminophenylazo)-25,26,27-tribenzoyloxy-28-hydroxycalix [4]arene, have been synthesized. It has been observed that the coupling reaction of diazonium salt obtained from 4-phenylazoaniline with bisphenol-A gives tetrakis- while those derived from 5-(4-aminophenylazo)-25,26,27-tribenzoyloxy-28-hydroxycalix [4] arene give partially substituted bisphenol-A analogues.
