The maternal recognition of pregnancy is the period when the conceptus signals its presence to the mother. This is an important moment of pregnancy, which can be decisive for the progress of pregnancy. During gestation, there is a series of events involving progesterone and prostaglandins produced by corpus luteum, a temporary gland formed from a single ovulation follicle. The progesterone produced by corpus luteum is a steroid involved in both ovarian cyclicity and the establishment and maintenance of pregnancy in most mammals. Some peculiarities of the events involved in the maternal-fetal relationship during pregnancy recognition among domestic species have been discussed in this review, one of them is the key role of interferon-tau protein (INF-T)...

Ultrastructural aspects of the tongue in Magellanic Penguins Spheniscus magellanicus (Forster, 1781) Biological Sciences
Guimarães, Juliana Plácido; Mari, Renata de Britto; Le Bas, Alfredo; Miglino, Maria Angélica.
The tongue of birds presents diversified morphologic characteristics, related directly their feeding habits and may be adapted to food capture. Penguins of the Spheniscidae family are pelagic birds that are totally adapted to the marine environment.  The objective of this study was to describe the morphology of the tongue in Magellanic penguins (Spheniscus magellanicus). In order to investigate these characteristics, six tongues of juvenile S. magellanicus were collected and their morphology analyzed macroscopically and microscopically.  The tongue of the Magellanic penguin has a fusiform shape with a round apex that is narrower than the root, following the shape of the beak.  The epithelium of the tongue of the Magellanic penguin showed to be stratified...
