In mammals, male embryos grow faster. Equine embryo size is highly variable for same developmental stage, with no reported relation to sex nor gene expression. Our objective was evaluate expression sexual dimorphism on equine D8 blastocysts. Non-nursing, Saddlebred mares located 2 experimental farms were inseminated the semen of one unique stallion per farm. At 8 d post ovulation, 17 and 11 fro...

We present some new supersymmetric solutions of massive IIA supergravity involving D0-branes, a D8-brane and a string. For the bosonic fields we use a general ansatz with SO(8) symmetry.

D8/17, a B cell alloantigen, and its occurrence with DR/DQ antigens was examined in 54 patients with rheumatic heart disease and matched North Indian controls. Thirty-four patients (62.9%) carried D8/17 as compared with a frequency of 12.5% in controls (X2 by Yates', 18.75; p<0.0001). A marginally increased frequency ofhuman leukocyte antigen (HLA)-DR3 (44.2% vs. 28.8%) and a significantly redu...

(1) Let G be a group and H ⊂ Z(G) a subgroup such that G/H is cyclic. Prove that G is abelian. Conclude that every group of order p2 (p a prime number) is abelian and that the centre of any non-abelian group of order p3 has p elements. (2) (?) Let H be a normal subgroup of a p-group G, H 6= {e}. Prove that H∩Z(G) 6= {e}. In particular, one obtains that any normal subgroup with p-elements is con...
