We report here on an extremely rare case of an intrathyroidal branchial cleft cyst. Intrathyroidal branchial cleft cyst is rare disease entity and it has nonspecific findings on sonography, so the diagnosis of the lesion is very difficult. However, during aspiration, if pus-like materials are aspirated from a thyroid cyst, we should consider the possibility of intrathyroidal branchial cleft cys...
Children with craniofacial abnormalities provide some of the most difficult challenges for anesthesiologists today. Whether the patient is scheduled for reconstructive surgery or a procedure unrelated to their anomaly, the care of these patients can be consuming and demanding. Since 1967 when the plastic surgeon Paul Tessier successfully demonstrated the correction of many deformities once thou...
Neurons of cranial sensory ganglia are derived from the neural crest and ectodermal placodes, but the mechanisms that control the relative contributions of each are not understood. Crest cells of the second branchial arch generate few facial ganglion neurons and no vestibuloacoustic ganglion neurons, but crest cells in other branchial arches generate many sensory neurons. Here we report that th...
BACKGROUND Branchial cleft anomalies constitute a frequently encountered and commonly non-lethal disease in otolaryngology, and result from aberrant embryonic development. The third branchial cleft fistula is one of the four known specific types of branchial cleft anomalies, and always presents as recurrent neck abscess and suppurative thyroiditis. Here, we report an unexpected death due to sev...
The aim of this study was to construct, expression of a novel recombinant chimeric protein consisting of Pyruvate dehydrogenase beta subunit (PDHB) and high antigenic region of integral membrane lipoprotein P80 of Mycoplasma agalactiae as a potential diagnostic tool. The full-length sequence of pdhb and a portion of antigenic regions of P80 were selected and analyzed by CLC ma...
Mycobacterium avium subsp. paratuberculosis (MAP) is the etiologic agent of Johne's disease in ruminants and there has been a shift in the public health approach to MAP and human diseases like Crohn's disease. The prevention of infection by MAP in ruminants is thought to deter the high impact of economic losses in the level of dairy industry and possible spreading of this pathogen in dairy prod...
The homology of branchial arch segments in salamanders has been a matter of controversy since the last century. Many investigators term the most medial paired elements of salamander branchial arches "ceratobranchials" and the next distal paired elements "epibranchials." This suggests that the first two segmental elements of the salamander branchial arch are not homologous with elements occupyin...
glomerular development of the kidney was studied in newborn rats by electron microscopy. four different stages of glomerular development were defined: vesicle fonnation, s-shaped body stage, capillary loop fonnation, and glomerular maturation. in the fust stage, the mesenchymal cells form a spheroid mass. this is followed by the s-shaped body stage in which clefts appear in the mass. afterwards...
Focal facial dermal dysplasia (FFDD) Type IV is a rare syndrome characterized by facial lesions resembling aplasia cutis in a preauricular distribution along the line of fusion of the maxillary and mandibular prominences. To identify the causative gene(s), exome sequencing was performed in a family with two affected siblings. Assuming autosomal recessive inheritance, two novel sequence variants...
