Effects of Habitat and Social Complexity on Brain Size, Brain Asymmetry and Dentate Gyrus Morphology in Two Octodontid Rodents
(Karger, 2016-04)
Navigational and social challenges due to habitat conditions and sociality are known to influence dentate gyrus (DG) morphology, yet the relative importance of these factors remains unclear. Thus, we studied three natural ...
Descrição anátomo-topográfica do coração da paca (Agouti paca)
(Universidade Federal do Rio Grande do Sul (UFRGS), 2010-01-01)
Background: The domestic animals heart is a conical hollow viscera, surrounded by pericardium, laterally compressed, accompanying the thorax shape. Atriums constituted the heart basis and their auricles partially bound the ...

Towards the resolution of a long-standing evolutionary question: muscle identity and attachments are mainly related to topological position and not to primordium or homeotic identity of digits
(Wiley, 2015-04)
Signaling for limb bone development usually precedes that for muscle development, such that cartilage is generally present before muscle formation. It remains obscure, however, if: (i) tetrapods share a general, predictable ...

Background: After the capybara, the Agouti paca is the largest rodent in the neotropical region, with a body weight that usually varies from 5 to 10 kg, but may reach up to 14 kg. Pacas reach sexual maturity at around 10 ...
Increased apoptosis in osteoclasts and decreased RANKL immunoexpression in periodontium of cimetidine-treated rats
(2013-02-01)
It has been demonstrated that histamine interferes with the recruitment, formation and activity of osteoclasts via H1- and H2-receptors. Cimetidine is a H2-receptor antagonist used for treatment of gastric ulcers that seems ...

(2016-01-01)
The postcranial anatomy of Crocodyliformes has historically been neglected, as most descriptions are based solely on skulls. Yet, the significance of the postcranium in crocodyliforms evolution is reflected in the great ...
