Introduction: Among different kinds of oral cavity cancers, the frequency of tongue cancer occurrence is more significant. Brachytherapy is the most common method to cure tongue cancers. Long sources are used in different techniques of tongue brachytherapy. The objective of this study is to asses the dose distribution around long sources, comparing different radioisotopes as brachytherapy sourc...

tongue base lesions have a diverse and extensive etiology. one of the benign tongue base lesions is schwannoma. schwannoma and neurofibroma are two tumors of the peripheral nerves originating in the nerve sheaths. schwannoma account for just over 1% of benign tumors which have been reported in the oral cavity and base of the tongue and with regard to its involved area in the oral cavity is very...

introduction: 90% of the tumors in the head and neck are squamous-cell carcinomas (hnscc), which have overall 5- year survival rate between 50% -60%. cd44 has been shown to be associated with the prognosis.  materials and methods: biopsy specimens of 51 patients with oral tongue scc were evaluated by immunohistochemistry (ihc) for the cd44 antibody.  results: there was no significant correlatio...

the aim of the present study was to investigate the light and electron microscopic structure of the tongue in white-eared bulbul (pycnonotus leucotis). six adult white-eared bulbul (3 males and 3 females) in shahrekord district were used in the investigation. samples of the apex, body and root of the tongue were prepared routinely for light and electron microscopic study. results showed that th...

Prominin-1 (CD133) is a cholesterol-interacting pentaspan membrane protein concentrated in plasma membrane protrusions. In epithelial cells, notably neuroepithelial stem cells, prominin-1 is found in microvilli, the primary cilium and the midbody. These three types of apical membrane protrusions are subject to remodeling during (neuro)epithelial cell differentiation. The protrusion-specific loc...

background and aims. there is no consensus about the effect of tongue thrusting on incisor position. the purpose of this study was to evaluate the position of anterior teeth in growing children with tongue thrust swallowing. materials and methods. in the present study 193 subjects with an age range of 9 to 13 years participated. all the patients were examined by a trained investigator and those...

The application of Cu-filled through-silicon via (TSV) in 3-D integrated circuit packaging faces several fabrication and reliability issues. In this study, we introduced a Cu-Ni alloy for TSV filling with a high filling speed and a reduced TSV protrusion. In particular, the characteristics of Cu-Ni via protrusions at various annealing temperatures (3200­450°C) were investigated with experimenta...

BACKGROUND Protrusions of cancer cells conferrers a vital function for cell migration and metastasis. Protein and RNA localization mechanisms have been extensively examined and shown to play pivotal roles for the functional presence of specific protein components in cancer cell protrusions. METHODS To describe genome wide RNA localized in protrusions of the metastatic human breast cancer cell...

BACKGROUND The APC tumour suppressor functions in several cellular processes including the regulation of β-catenin in Wnt signalling and in cell adhesion and migration. FINDINGS In this study, we establish that in epithelial cells N-terminally phosphorylated β-catenin specifically localises to several subcellular sites including cell-cell contacts and the ends of cell protrusions. N-terminall...
