The bHLH Transcription Factor, Hairy, Refines the Terminal Cell Fate in the Drosophila Embryonic Trachea
BACKGROUND The pair-rule gene, hairy, encodes a basic helix-loop-helix transcription factor and is required for patterning of the early Drosophila embryo and for morphogenesis of the embryonic salivary gland. Although hairy was shown to be expressed in the tracheal primordia and in surrounding mesoderm, whether hairy plays a role in tracheal development is not known. PRINCIPAL FINDINGS Here, ...
متن کاملHairy Strings
Zero modes of the worldsheet spinors of a closed string can source higher order moments of the bulk supergravity fields. In this work, we analyze various configurations of closed strings focusing on the imprints of the quantized spinor vevs onto the tails of bulk fields. We identify supersymmetric arrangements for which all multipole charges vanish; while for others, we find that one is left wi...
متن کاملReconstruction of the trachea.
Advances in surgical technique and in anaesthesia have made possible a more radical attack on lesions affecting the trachea. Although the number of patients presenting with such a tracheal lesion is small, it is important that they should be treated adequately. Tracheal reconstruction is indicated both for benign and for malignant neoplasms, most of which are found to arise in the lower third. ...
متن کاملSurgery of the Trachea
Surgical procedures on the trachea have only been undertaken within the past 50 years. Knowing the unique blood supply of the trachea and how to reduce tension on any anastomosis are key to a successful outcome. Tracheal conditions requiring surgery usually present with shortness of breath on exertion, and preoperative evaluation involves computed tomography and rigid bronchoscopy. Tracheal res...
متن کاملGlomangiomyoma of the Trachea
A glomus tumor is an uncommon soft tissue tumor that is most commonly found in the subungual area and a glomus originating in the trachea is extremely rare. Histologically and ultrastructurally, these tumors have been divided into three subtypes: classic glomus tumors, glomangiomas, and glomangiomyomas. Glomangiomyomas account for less than 10% of all glomus tumors and are the least common type...
