Familial aggregation of non-diabetic end-stage renal disease (ESRD) is found in African Americans and variants in the apolipoprotein L1 gene (APOL1) contribute to this risk. To detect genetic associations with milder forms of nephropathy in the high-risk families, analyses were performed using generalized estimating equations to assess relationships between(More)

Several drugs are available to treat hepatitis B. The most potent and the one with the lowest risk of resistance appears to be tenofovir (TDF). However there are several(More)

In 1984 Shubik proposed to consider, for each optimal matching, the union of the core of the game and the core of the subgames that are compatible with this matching. We prove in the present paper that(More)
