Oxygen uptake and carbon dioxide excretion by the branchial and postbranchial regions of adults of the lampreyGeotria australis in air

The Journal of Experimental Zoology, 1997
O2 uptake and CO2 excretion by the branchial and postbranchial regions of adults of the lamprey Geotria australis have been measured in humidified air at 15 and 5°C. At 15°C, the mean standard V(O2) for whole animals was 31.9 μl·gm-1·hr-1, which is similar to the interpolated V(O2) in water at the same temperature and time of year.

Alteration of Hox gene expression in the branchial region of the head causes homeotic transformations, hindbrain segmentation defects and atavistic changes

Seminars in Developmental Biology, 1995
A functional role of Hox genes in patterning the branchial region of the head was predicted on the basis of their expression patterns in rhombomeres, rhombencephalic neural crest cells and pharyngeal arch mesenchyme. The phenotypic consequences of the generation of both gain- and loss-of function Hox gene mutations not only strongly support this ...

Correlation between Loss of Middle Ear Bones and AlteredgoosecoidGene Expression in the Branchial Region Following Retinoic Acid Treatment of Mouse Embryosin Vivo

Biochemical and Biophysical Research Communications, 1997
The homeobox gene goosecoid marks the Spemann organizer in vertebrate gastrula embryos, and is expressed in the craniofacial region, body wall and limbs during organogenesis. Mouse mutants of goosecoid displayed a variety of phenotypes related to the expression pattern at mid-embryogenesis.

A homeotic transformation is generated in the rostral branchial region of the head by disruption of Hoxa-2, which acts as a selector gene

Cell, 1993
The Hoxa-2 gene was disrupted by homologous recombination. Homozygous mutant mice died at birth. Defects were found in the branchial region of the head, which corresponds to the Hoxa-2 rostral expression domain. While rhombomeric and neural crest cell (NCC) segmentation was not affected, mesenchymal NCC derivatives of the second arch were lacking, and ...

Receptive Fields and Properties of A New Cluster Of Mechanoreceptor Neurons Innervating the Mantle Region and the Branchial Cavity of the Marine MolluskAplysia California

Journal of Experimental Biology, 1991
ABSTRACTThe rostral LE cluster (rLE) is a new set of mechanoreceptor neurons of the abdominal ganglion innervating the mantle area, the branchial cavity, the gill and the siphon of the marine mollusk Aplysia californica Cooper. We have compared the organization of rLE cell receptive fields with that of three other clusters of sensory neurons in the ...

Sites of Aspecific ATP-Phosphohydrolase Activity in the Branchial Region of Chick Embryos, with Particular Emphasis on the Myogenic Cell Population

European Journal of Morphology, 1999
The distribution pattern of unspecific ATP-phosphohydrolase (ATP-PH) activity was studied in serial sections through the branchial region of chick embryos from HH stage 14 to 27. A selective reaction was found in the prospective myogenic mesoderm of voluntary muscles of the first three branchial arches. This property initially characterized uncondensed

Segmentation and specification in the branchial region of the head: the role of the Hox selector genes.

The International journal of developmental biology, 1998
Hox genes are segmentally expressed in the developing vertebrate hindbrain, neural crest cells and pharyngeal arches suggesting an important role in patterning these structures. Here we discuss the cellular and molecular mechanisms controlling segmentation and specification in the branchial region of the head.

Induction of ectopic external gills and tetrapodomorph-like skeletal elements through homeotic transformations in the salamander branchial region

AbstractHomeotic transformations are morphological changes associated with alterations of identities of segments in serially repeated systems and these changes may be a source of modifications in body plan evolution. Retinoic acid (RA) signaling has previously been shown to induce homeotic transformations in the vertebral column, although its role in ...
