Nonmelanoma skin cancers (NMSCs), which include basal and squamous cell cancers are the most common human cancers. BCCs have a relatively low metastatic rate and slow growth and are frequently underreported. Whilst there is a definite role of sunexposure in the pathogenesis of BCC, several additional complex genotypic, phenotypic and environmental factors are contributory. The high prevalence a...

BACKGROUND The Xeroderma pigmentosum complementation group C protein (XPC) is a general sensor of damaged DNA. Individuals carrying a mutation in XPC genes exhibit marked photosensitivity and increased occurrence of skin cancers. Little is known about the distribution of XPC protein in basal cell carcinoma (BCC). AIM To determine whether the XPC protein is associated with basal cell carcinoma...

BACKGROUND AND DESIGN Basal cell carcinoma (BCC) of the skin is the most common neoplasm in white populations, and solar radiation is generally accepted to be the dominant environmental risk factor for this disease. However, little information is available on the nature of the relationship between BCC and sunlight. The purpose of this study was to evaluate the nature of the relationship between...

This study is an applied study conducted to evaluate and compare the efficiency of Iran's regional power companies using conventional and network Data Envelopment Analysis methods. Iran's regional power companies use two- phased process to transmit power. Using applied approach, the performance and efficiency of these companies were measured with network and conventional methods, and they were ...

Background. Photodynamic therapy (PDT) has become a therapeutic option for basal cell carcinoma (BCC) in the last decade. Objectives. To study the results and predictors of BCC response to treatment with PDT and to evaluate fluorescence diagnosis of BCC. Methods. A descriptive, retrospective, and observational study was carried out. Patients with biopsy-confirmed BCC who were treated with methy...

Abbreviations used: F-FDG: fluor-18-fluorodeoxyglucose BCC: basal cell carcinoma CK: cytokeratin CT: computed tomography MRI: magnetic resonance imaging PET/CT: positron emission tomography and computed tomography INTRODUCTION The incidence rate of nonmelanoma skin cancer in the United States is estimated at 2.8 million new cases each year, of which, 80% are of basal cell carcinoma (BCC) type. ...

Squamous cell carcinoma (SCC) and basal cell carcinoma (BCC) are the most frequent skin cancers in humans. An intact immune system is critical for protection against SCC since organ transplant recipients (OTR) have a 60- to 100-fold higher risk for developing these tumors. The role of the innate immune system in tumor immunosurveillance is unclear. Our aim was to determine the expression of sel...

Optical coherence tomography (OCT) has been shown to be of clinical value in imaging basal cell carcinoma (BCC). A novel dual OCT-video imaging system, providing automated registration of OCT and dermoscopy, has been developed to assess the potential of OCT in measuring the degree of sub-clinical spread of BCC. Seventeen patients selected for Mohs micrographic surgery (MMS) for BCC were recruit...

BACKGROUND Microcystic adnexal carcinoma (MAC), desmoplastic trichoepithelioma (DTE) and morpheaform basal cell carcinoma (BCC) frequently impose a considerable differential diagnostic challenge and immunohistochemistry is often used as a differentiating diagnostic adjunct. METHODS Using standard immunohistochemical techniques, we examined 21 examples of DTE, 17 examples of morpheaform BCC an...

The study of BCK-algebras was initiated by Iséki [7] as a generalization of the concept of set-theoretic difference and propositional calculus. Iséki posed an interesting problem; whether the class of BCK-algebras is a variety. In connection with this problem Komori introduced in [9] a notion of BCC-algebra which is a generalization of a BCK-algebra and proved that the class of all BCC-algebras...
