BACKGROUND The purpose of this study was to describe the relationship of p16 and epidermal growth factor receptor (EGFR) expression with survival in surgically treated patients who had oropharyngeal or oral cavity squamous cell carcinoma (SCC). METHODS Tissue from 36 patients with oropharyngeal SCC and 49 patients with oral cavity SCC treated between 1997 and 2001 was imbedded and immunostain...

There are three hypotheses regarding the relationship between Self-Concept Clarity (SCC) and Internet use. It was argued that use: 1) decreases SCC, 2) increases 3) does not relate with SCC. The present study, in form of a systematic meta-analytic synthesis, aimed to explore: a) extent empirical evidence can support each hypothesis; b) how use-SCC addressed across studies; c) intensity use –SCC...

Colonic small cell carcinomas (SCCs) are rare, aggressive tumors characterized by early metastasis and poor prognosis. We describe a 39-year-old man with a history of ulcerative colitis and left colon adenocarcinoma resected at an outside institution who presented with hematochezia and proctalgia. Work-up revealed left colon SCC with liver metastases. After his excellent response to neoadjuvant...

We established a human tissue explant model to facilitate study of cutaneous squamous cell carcinoma. We accomplished this by implanting debulked SCC, from surgical discard, into nude rats. Human SCC remained viable and continued to proliferate for at least 4 weeks and showed evidence of neovascularization. At 4 weeks, SCC implants showed a trend toward increased PCNA positive cells compared to...

In this study, first, different mix design of four types of Self-Compacting Concrete (SCC), 1. SCC consisted of only nanosilica, 2. SCC included only microsilica, 3. SCC consisted of both microsilica and nanosilica and 4. SCC without microsilica and nanosilica called as control mix, were casted and tested to find out the values of the Slump Flow, L-Box and 7 and 28 days compressive strength. Th...

BACKGROUND An increasing incidence of oral carcinoma among young adults has been reported in the U.S. and Europe. Although the association between human papillomavirus infection and tonsillar carcinoma is now well established, to the authors' knowledge little is known about incidence trends in tonsillar carcinoma among younger adults. The objective of the current study was to explore the trends...

Verrucous carcinoma (VC) of the penis is an uncommon squamous tumor that pursues a biologically indolent course. Unlike conventional squamous cell carcinoma (SCC) of the penis, pathogenic roles for human papillomavirus (HPV) infection and p53 mutation have not been reported in VC. We compared the immunohistochemical expression of Mdm2 and p53 in 7 cases of VC and 7 cases of SCC. The Mdm2 gene p...

Background and Objective: Basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) are two common tumors of the skin. In some cases, distinction between BCC and SCC can be difficult. This study aimed to clarify this uncertainty through immunohistochemical analysis. In this respect, epithelial membran...

The reluctance in utilizing the advantages of Self Compacting Concrete (SCC) in Bahrain stems from two contributing factors: Lack of research or published data pertaining to locally produced SCC, and a feeling of doubt and uncertainty in the minds of practicing engineers about reliability and suitability of SCC in hardened stage. The primary aim of this study is to explore the influence of visc...

Squamous cell carcinoma (SCC) is the most prevalent malignant neoplasm of the oral cavity. The conventional tumour and several histologic subtypes of SCC present morphologic features and specific behaviour when they occur in the oral mucosa. For example, basaloid SCC is an aggressive tumour and verrucous carcinoma has the lowest invasive and metastatic potential; however, the clinical and biolo...
