They were followed for an average of 6.6 years (range, five to nine years), which is the longest follow-up of a total knee(More)

The objectives of this study were to evaluate the effect using two doses of progesterone (P4) releasing devices in two different programs on reproductive performance of anestrous dairy cows. Cows (n = 1555) not detected in estrus by 10 d before the planned start of the seasonal breeding program and in which no CL was palpable were treated with an(More)
In seventeen children with catastrophic loss of the femoral head, the hip was salvaged by greater trochanteric arthroplasty. The average follow-up of these patients was eleven years, and fourteen patients were followed to skeletal maturity or longer. In Group I, consisting of four patients with greater trochanteric arthroplasty alone, good initial stability(More)

Clinical studies have shown recombinant human erythropoietin (r-HuEPO) to be effective in correcting the anemia of zidovudine-treated patients infected with human(More)
