The ubiquitin-proteasome system has a crucial role in maintaining and regulating cellular homeostasis including carcinogenesis. UBE2Q2, also designated Ubci, is one of the ubiquitin-conjugating enzymes (E2), and it has been reported that mRNA of UBE2Q2 is highly expressed in human head and neck squamous cell carcinoma, particularly hypopharyngeal carcinoma. However, the involvement of UBE2Q2 in...

purpose: to evaluate of proton therapy (pt) for neurosurgery patients and is also to explain the need for this system in iran. methods: a literature review was conducted (1984–2016). the strategy included a combination of keywords including proton therapy, neck, neurosurgery, brain, head, tumor, spine, arteriovenous malformation (avms), cervical and spine in database of pubmed. new generation p...

A new antibody associated with squamous cell carcinoma, YM-Antibody, containing components of pI 5.95-6.10 fractions, was produced from cell cultures of squamous cell carcinoma of the larynx. To elucidate the immunological characteristics of YM-Antibody, it and 6 other commercially available antibodies were investigated immunohistochemically by applying them to squamous cell carcinomas and non-...

Head and neck cancer, including oral cancer, is the sixth most common cancer in humans worldwide. More than 90% of oral cancers are of squamous cell carcinoma type. Recent studies have shown a strong relationship between human papillomavirus (HPV) infection and head and neck cancer, especially oropharyngeal squamous cell carcinoma (OPSCC) and oral squamous cell carcinoma (OSCC). Moreover, the i...

BACKGROUND squamous cell carcinoma is the second most common type of skin malignancy and may evolve to regional lymph node and distant metastases. OBJECTIVE The objective of this study was to evaluate patients with head and neck cutaneous squamous cell carcinoma to identify its clinical and histopathological characteristics, as well as the frequency of local recurrence and metastasis. METHO...

The head and neck region consists of subsites, including the oral cavity, pharynx, larynx, nasal sinuses, salivary glands, and orbits, and contains important organs performing functions that are directly related to the Quality of Life (QOL), such as chewing, swallowing, and phonation. It has been reported that 32% of head and neck cancers occur in the oral cavity, 24% in the larynx, 35% in the ...

Head and neck squamous cell carcinoma (HNSCC) represents a large majority of cancers arising from the head and neck, especially the oral cavity. Despite advances in therapy, the five-year survival rate remains low due to the number of patients presenting advanced stages of the disease. The role of epithelial-mesenchymal transition (EMT) in tumorigenesis in HNSCC remains unexplored. The current ...

Head and neck squamous cell carcinoma (HNSCC), accounting for more than 80% in head and neck malignancies, kills thousands of people a year in the world. Despite most of the patients are more than 45, and the occurrences of head and neck cancer shows a decreasing trend; however, horribly, the incidences of the patients under 45 years old is steadily increasing. Hence, it's of vital importance t...

AIM We evaluated the prognostic value of vasohibin-1 (VASH1) expression in head and neck squamous cell carcinoma. MATERIALS AND METHODS Immunohistochemistry for VASH1 and cluster of differentiation 34 (CD34) was performed on 61 head and neck squamous cell carcinoma specimens. The association between VASH1 expression in the tumour and clinical outcomes was analyzed statistically. RESULTS VAS...
