What is Classical Typical Cushing’s Syndrome? Classical or typical hyperadrenocorticism is a syndrome caused by excess secretion of cortisol from the adrenal gland(s). Approximately 80 to 85% of cases of spontaneous hyperadrenocorticism in both dogs and cats are due to pituitary-dependent hyperadrenocorticism, with the remainder due to a functional adrenocortical tumor. Clinical signs include p...

Blood samples from 159 birds of the New-world family Tyrannidae (the flycatchers) from the eastern plains of Colombia, were examined for haematozoa parasites, in 1999-2000. Haematozoa were detected in six of 20 species. The overall prevalence was 10.1%. The most common parasites detected were microfilariae, followed by Trypanosoma and Plasmodium. The highest prevalence (9.6%) was found in the O...

Play has been defined as apparently functionless behaviour, yet since play is costly, models of adaptive evolution predict that it should have some beneficial function (or functions) that outweigh its costs. We provide strong evidence for a long-standing, but poorly supported hypothesis: that early social play is practice for later dominance relationships. We calculated the relative dominance r...

The male red-bellied newt (Cynops pyrrhogaster) approaches the female's cloaca prior to performing any courtship behaviour, as if he is using some released substance to gauge whether she is sexually receptive. Therefore, we investigated whether such a female sexual attractiveness pheromone exists. We found that a tripeptide with amino acid sequence Ala-Glu-Phe is secreted by the ciliary cells i...
