basal cell carcinoma (bcc) is currently the most common cutaneous cancer found in humans. although it generally shows a relatively benign course (bccl), some cases show aggressive behavior (bcc2). until recently, traditional histologic diagnostic criteria have failed to discriminate unequivocally between bcc 1 and bcc2. in this study we selected 50 cases of bcc and categorized them into two gro...

Photodynamic therapy (PDT) involves the activation of a photosensitizing drug by visible light to produce activated oxygen species which promote tumour destruction. Despite a rising tide of publications in recent years, PDT was first described 100 years ago. Generalized and severe phototoxicity from early crude photosensitizers limited development, although partial purification produced a haema...

Intracellular bacteria are characterized by genome reduction. The 422,434-base pair genome of Buchnera aphidicola BCc, primary endosymbiont of the aphid Cinara cedri, is approximately 200 kilobases smaller than the previously sequenced B. aphidicola genomes. B. aphidicola BCc has lost most metabolic functions, including the ability to synthesize the essential amino acid tryptophan and riboflavi...

BACKGROUND Arborizing vessels (AVs) are dermoscopically defined as telangiectasias with distinct treelike branching, and are a characteristic feature of basal cell carcinoma (BCC). However, AVs are observed in various conditions other than BCC. OBJECTIVE The aim of this study was to investigate skin diseases showing AV and investigates dermoscopic differences between BCC and non-BCC. METHOD...

The concept of fuzzy multiply positive BCC-ideals of BCC-algebras is introduced, and then some related results are obtained. Moreover, we introduce the concept of T -fuzzy multiply positive implicative BCC-ideals of BCC-algebras and investigate T -product of T -fuzzy multiply positive implicative BCC-ideals of BCC-algebras, examining its properties. Using a t-norm T , the direct product and T -...
