(7) The ratio of the contents of the two major mammalian ganglioside fractions GD1a and GT1b is generally in the range of 1.0 and even higher; in the heterothermic platypus from the monotremes and in hibernators among the placental mammals, however, it is much lower (about 0.8).
(8) Because monotremes and marsupials diverged independently from eutherian mammals, this finding implies that the whole human X short arm region is a relatively recent addition to the X chromosome in eutherian mammals.
(9) Several lines of evidence suggest that electroreception has evolved independently in this monotreme.
(10) Since marsupials and monotremes diverged independently from eutherians, these data suggest that HSA 21 genes were originally located in two separate autosomal blocks.

(17) A region represented by the short arm of the human X is common to the X in all eutherians, but is autosomal in marsupials and monotremes; thus it was not a part of the original X, and must have been acquired by the X early in the eutherian radiation.
(18) The enamel of the fossil monotreme is prismatic and tubular and displays large areas of Pattern 2 prism packing.
(19) This estimate agrees well with similar estimates made using alpha- and beta-globin sequences, in contrast to widely differing estimates of dates of divergence for monotremes using the same three globin chains.
(20) Xenoantisera directed against human heavy chain isotypes allowed the serological identification of IgM and IgG immunoglobulins in the echidna (Tachyglossus aculeatus), a monotreme which is one of the most primitive species of extant mammals.

(11) A retrospective study of 36 patients with postcesarean peritonitis has identified risk factors contributing to this complication, with urogenital inflammations in the past or during the current pregnancy, and an unreplaced gross blood loss as the major ones.
(12) These are responsible for some cases of urogenital infections, and more recent studies show that they are associated with perinatal disorders.
(13) A distinct fascial septum, the lamina terminalis, connecting the medial and lateral walls of the fossa to form its anterior boundary, was consistently found as a dense fibrous component attaching inferiorly to the posterior aspect of the urogenital diaphragm.
