1. Sistematização da aorta abdominal, ramos colaterias parietais e viscerais e ramos terminais em coelhos da raça Nova Zelândia (Oryctolagus cuniculus)
In this study was defined the pattern, the variations and distribution of the parietal and visceral collateral branches and terminal branches of the abdominal aorta in New Zeland rabbits (Oryctolagus cuniculus), being used 30 animals, 14 males e 16 females, young adults. The arterial system was filled with red colored latex through the thoracic aorta in the

2. Avaliação da morfologia pós-operatória das células do endotélio corneano de coelhos na região periférica perincisional comparativamente à região central
A manutenção da morfologia normal do endotélio da córnea é um importante indicador da integridade funcional. A reparação endotelial frente a um trauma, em coelhos, ocorre por migração, hipertrofia e mitose celular. Objetivou-se comparar a morfologia das células do endotélio, da região periférica perincisional à região central, da córnea de co

4. Malocclusions in guinea pigs, chinchillas and rabbits
The types of malocclusions encountered in rodents and lagomorphs are classified. Diagnosis, treatment, and prognosis are reviewed. Some malocclusions are curable, whereas others can only be controlled. The need to perform a complete oral examination and to find a cause for the condition is stressed, as it will seriously affect the prognosis.

5. Early tertiary elephant-shrews from Egypt and the origin of the Macroscelidea.
Recent expeditions to the Fayum Depression, Egypt, have made possible the discovery of mandibles and a maxilla of a new genus and species of late Eocene elephant-shrew as well as initial evidence of the upper dentition of the early Oligocene taxon Metoldobotes. These fossils demonstrate that macroscelideans underwent a significant radiation in the Early Tert

6. Molecular phylogeny of Rodentia, Lagomorpha, Primates, Artiodactyla, and Carnivora and molecular clocks.
Phylogenetic analysis of DNA sequences from primates, rodents, lagomorphs, artiodactyls, carnivores, and birds strongly suggests that the order Rodentia is an outgroup to the other four mammalian orders and that Artiodactyla and Carnivora belong to a superordinal clade. Further, there is strong evidence against the Glires concept, which unites Lagomorpha and

7. Synonymous nucleotide substitution rates in mammalian genes: implications for the molecular clock and the relationship of mammalian orders.
Synonymous substitution rates have been estimated for 58 genes compared among primates, artiodactyls, and rodents. Although silent sites might be expected to be neutral, there is substantial rate variation among genes within each lineage. Some of the rate variation is associated with G + C content: genes with intermediate G + C values have the highest rates.

8. Identification of a new, abundant superfamily of mammalian LTR-transposons.
A new superfamily of mammalian transposable genetic elements is described with an estimated 40,000 to 100,000 members in both primate and rodent genomes. Sequences known before as MT, ORR-1, MstII, MER15 and MER18 are shown to represent (part of) the long terminal repeats of retrotransposon-like elements related to THE1 in humans. These transposons have stru

9. The IgA heavy-chain gene family in rabbit: cloning and sequence analysis of 13 C alpha genes.
Southern analysis has previously shown that the rabbit genome contains multiple genes coding for the constant regions of IgA heavy chains. In the present study, clones containing these C alpha genes have been isolated from cosmid and phage libraries. Restriction mapping and Southern analysis of the clones identified 13 non-allelic C alpha genes; 11 of the ge

10. Comparative aspects of trophoblast development and placentation
Based on the number of tissues separating maternal from fetal blood, placentas are classified as epitheliochorial, endotheliochorial or hemochorial. We review the occurrence of these placental types in the various orders of eutherian mammals within the framework of the four superorders identified by the techniques of molecular phylogenetics. The superorder A

11. Geometry of the semicircular canals and extraocular muscles in rodents, lagomorphs, felids and modern humans
The vestibulo-ocular reflex (VOR) exacts compensatory movements of the extraocular muscles in response to stimulation of the semicircular canals to allow gaze fixation during head movements. In this study, the spatial relationships of these muscles and canals were investigated to assess their relative alignments in mammalian species commonly used in studies
