Behavioural effects of prenatal metallic mercury inhalation exposure in rats.
The effects of administration by inhalation of metallic mercury vapour (Hg0) to pregnant rats, approximately corresponding to doses of 0.2 mg Hg0/kg/day (high dose) or 0.07 mg Hg0/kg/day (low dose),Expand

Limb development in a "nonmodel" vertebrate, the direct-developing frog Eleutherodactylus coqui.
Mechanisms that mediate limb development are regarded as highly conserved among vertebrates, especially tetrapods. Yet, this assumption is based on the study of relatively few species, and virtuallyExpand

Cranial neural crest cells contribute to connective tissue in cranial muscles in the anuran amphibian, Bombina orientalis.
The contribution of cranial neural crest cells to the development and patterning of cranial muscles in amphibians was investigated in the phylogenetically basal and morphologically generalized frog,Expand

Muscular derivatives of the cranialmost somites revealed by long‐term fate mapping in the Mexican axolotl (Ambystoma mexicanum)
SUMMARY The fate of single somites has not been analyzed from a comparative perspective with modern cell‐marking methods. Most of what we know is based on work using quail‐chick chimeras.Expand

Patterns of spatial and temporal visceral arch muscle development in the Mexican axolotl (Ambystoma mexicanum)
Vertebrate head development is a classical topic that has received renewed attention during the last decade. Most reports use one of a few model organisms (chicken, mouse, zebrafish) and have focusedExpand

Limb chondrogenesis in Graptemys nigrinoda (Emydidae), with comments on the primary axis and the digital arch in turtles
The early development of skeletal structures of manus and pes was studied using whole-mount, alcian-blue-stained embryos at different stages in an ontogenetic series of Graptemys nigrinoda. SequencesExpand

Role of cranial neural crest cells in visceral arch muscle positioning and morphogenesis in the Mexican axolotl, Ambystoma mexicanum
The role of cranial neural crest cells in the formation of visceral arch musculature was investigated in the Mexican axolotl, Ambystoma mexicanum. DiIExpand

Identification of epistasis through a partial advanced intercross reveals three arthritis loci within the Cia5 QTL in mice
Identification of genes controlling complex diseases has proven to be difficult; however, animal models may pave the way to determine how low penetrant genes interact to promote disease development.Expand

Cranial neural crest cell migration in the Australian lungfish, Neoceratodus forsteri
SUMMARY A crucial role for the cranial neural crest in head development has been established for both actinopterygian fishes and tetrapods. It has been claimed, however, that the neural crest isExpand

The Developmental Pattern of the Musculature Associated with the Mandibular and Hyoid Arches in the Longnose Gar, Lepisosteus osseus (Actinopterygii, Ginglymodi, Lepisosteiformes)
This is the first in a planned series of studies in which we examine the cranial muscle ontogeny of exemplar taxa of actinopterygian clades to obtain a better understanding of the evolution of theExpand
