Role of the paired-like gene Pitx1 in Xenopus head development.
The process of head development is complex and with the exception of the hindbrain region, it is unlike trunk development in as much as it does not involve discrete segmentation. Recent evidence suggests that the paired-like family of genes play a role in regulating anterior development. To further …

Molecular Studies on Head Development of the Amphipod Crustacean Parhyale hawaiensis
Der adulte Kopf bilateralsymmetrischer Tiere ist eine anteriore, meist tagmatisierte morphologische Einheit. In segmentierten Spezies liegen der Entwicklung der anterioren Kopfsegmente andere genetische und molekulare Mechanismen zugrunde als der der posterioren Segmente, die auf gruppen- und …

Evaluation System for Craniosynostosis Surgeries with Computer Simulation and Statistical Modelling
… evaluate their surgeries. We aimed to develop a head model of a craniosynostosis patient, which allows neurosurgeons to perform any potential surgeries on it so as to simulate the postoperative head development. Therefore, neurosurgeons could foresee the surgical results and is able to select the …

The extreme anterior domain coordinates brain and craniofacial development
The head is one of the most complex and important parts of the body. The shape of the head is largely determined by the size of the brain and morphology of the facial skeleton. These tissues consist of different cell types and undergo distinct developmental programs. However, development of the …

Integration of High Residue/No-till and Farmscaping Systems in Organic Production of Broccoli
… due to cool weather conditions during broccoli head development (October), increasing head size, uniformity, and marketability. In 2004, broccoli yield in CT plots was either equal or slightly higher than NT (9.5 vs. 9.0 t ha-1). However, in 2005, broccoli yield in CT plots was significantly …

Regulation of segment polarity genes in the head region of different arthropods
Head segmentation in insects, as reflected by the model system Drosophila melanogaster, is less well understood in comparison to the trunk. While the gnathal segments (mandibular, maxillary, labial) are patterned in a way similar to the trunk, distinct molecular mechanisms underlie the …

Funktion und Evolution von hochkonservierten Kopfgenen im Reismehlkäfer Tribolium castaneum
Die anterior-posterior Achse von bilateral symmetrischen Organismen (Bilateria) ist unterteilt in eine posteriore Region, die durch die Expression der hoch konservierten HOX-Cluster Gene gekennzeichnet ist und eine anteriore Region, die frei von deren Expression ist. Dennoch sind einige hoch …

Individual variability in the behaviour and morphology of larval Atlantic cod (Gadus morhua, L.)
… could enable the farmer to mitigate the development of behaviours and morphologies that are not conducive with welfare and production. Such information would be especially useful in the rearing of species such as Atlantic cod, which are highly cannibalistic in the larval and early …
