Quantum dots (QDs) are a new class of fluorescent probes to detect biomarker expression. The role of caveolin-1 (Cav-1) in tongue squamous cell carcinoma (TSCC) is still unknown. This study aimed to investigate the expression profile of Cav-1 in carcinogenesis and development of TSCC by QDs immunofluorescence histochemistry (QDs-IHC) and discuss the relationship between the Cav-1 expression and...

variation of the branches of the external carotid artery (eca) is well known, but it is extremely rare for the occipital artery (oa) to arise from the internal carotid artery (ica). a 87-year-old man was found to have this anatomical variation on the right side by threedimensional computed tomography angiography for vascular mapping of the carotid arteries before superselective intra-arterial c...

PURPOSE Urokinase-like Plasminogen Activator Receptor (uPAR) is overexpressed in a variety of carcinoma types, and therefore represents an attractive imaging target. The aim of this study was to assess the feasibility of two uPAR-targeted probes for PET and fluorescence tumor imaging in a human xenograft tongue cancer model. EXPERIMENTAL DESIGN AND RESULTS Tumor growth of tongue cancer was mo...

In the present study, the presence of extracellular matrix components, including collagenous and elastic fibers, and the expression of their key regulating enzymes, were investigated in different stages of hamster tongue carcinoma development. Immunohistochemical and computer-assisted morphological analyses were performed to quantify the staining intensity and area (integral optical density) of...

Kikuchi-Fujimoto disease (KFD), also known as histiocytic necrotizing lymphadenitis, is a rare self-limiting disorder typically affecting the cervical lymph nodes (LNs), which is often misdiagnosed as other LN-associated diseases. KFD frequently presents with necrotic lesions and recurrences, which are also features of metastatic LNs. Clinicians may thus suspect LN metastasis when they encounte...

AIM The tongue plays a major role in articulation. Speech outcome depends on the site of lesion, extent of resection, and flexibility of the remaining structures. The aim of this study is to evaluate the speech outcome measures such as sounds that are misarticulated and speech intelligibility and its connection to tumor site before and after surgery. METHODOLOGY Totally, 24 (12 pre- and 12 po...

CONCLUSIONS Because computed tomography (CT) lymphography provides preoperative images of anatomic relationships between a tumor, its associated lymph vessels, and the sentinel lymph node (SLN), it may aid in directing the SLN biopsy for management of early tongue cancer. OBJECTIVES SLN biopsy using a radioisotope (RI) generally has been performed in head and neck cancer. However, this method...

IMPORTANCE Magnetic resonance imaging (MRI) has the advantage of imaging swallow function at any anatomical level without changing the position of patient, which can provide detailed information than modified barium swallow, by far the gold standard of swallow evaluation. OBJECTIVE To investigate the use of real-time MRI in the evaluation of swallow function of patients with tongue cancer. ...

We investigated the susceptibility of 4-nitroquinoline 1-oxide (4-NQO)-induced tongue carcinogenesis in male CB6F1-Tg-rasH2 @Jcl mice (Tg mice). The Tg mice were administered 4-NQO (20 p.p.m. in drinking water) for 2, 4, 6 or 8 weeks, and thereafter they were untreated up to week 24. At week 24, a higher incidence (80%) of tongue neoplasm with dysplasia was noted in the mice that received 4-NQO...
