BACKGROUND Basal cell carcinoma (BCC) is the most frequently encountered neoplasm worldwide. While nodular BCC is the most frequent clinical subtype, other forms of BCC, such as superficial, cystic, morpheiform, infiltrative, and pigmented may also be encountered. CASE PRESENTATION We present the case of a 67-year-old male with a relatively well-defined infiltrative, pigmented plaque with mul...
The estuarine copepod Acartia tonsa naturally carried diverse strains of bacteria on its body. The bacterial community composition (BCC) remained very conservative even when the copepod was fed different axenic algal species, indicating that the food per se did not much affect BCC associated with the copepod. In xenic algal treatments, however, copepod-associated BCC differed with each alga fed...
Basal cell carcinoma (BCC) is the most frequent cutaneous tumour. Having as aim the identification of the clinical-evolutional and histopathologic aspects of the basal cell carcinomas, we have undertaken a retrospective study for a period of 5 years, from 1st January 2004 to 31st December 2008, on 706 patients interned in the Dermatology Clinic of Craiova, whom indicated 738 tumours. A clinical...
The accurate and fast identification of crystallographic defects plays a key role for the analysis of atomistic simulation output data. For face-centered cubic (fcc) metals, most existing structure analysis tools allow for the direct distinction of common defects, such as stacking faults or certain low-index surfaces. For body-centered cubic (bcc) metals, on the other hand, a robust way to iden...
Skin cancer is a late complication of ionizing radiation. Two skin neoplasms prominent Basal Cell Carcinoma (BCC) and Squamous Cell Carcinoma (SCC) are the most famous complications of radiotherapy. Basal Cell Carcinoma (BCC) is the most common human malignant neoplasm. Many genetic and environmental factors are involved in its onset. BCC is observed in sunexposed areas of skin. Some patients w...
Tumor hypoxia is a hallmark of malignant tumors, and is a major factor in the resistance to anti-cancer therapies, particularly radiotherapy. Indeed, tumor blood flow often fluctuates, and thus the oxygen supply is often reduced, thereby inducing tumor hypoxia. We decided to explore whether post-occlusive reactive hyperemia, a physiological reaction known to occur in normal tissues, could be ...
In Bipartite Correlation Clustering (BCC) we are given a complete bipartite graph G with ‘+’ and ‘−’ edges, and we seek a vertex clustering that maximizes the number of agreements: the number of all ‘+’ edges within clusters plus all ‘−’ edges cut across clusters. BCC is known to be NP-hard [5]. We present a novel approximation algorithm for k-BCC, a variant of BCC with an upper bound k on the ...
We describe conventional and high-resolution transmission electron microscopy ~HRTEM! characterization of the microstructure of sputtered NiFe/Cu giant magnetoresistance spin valves ~Cu/FeMn/NiFe/Cu/NiFe! sandwiched between thick Nb contact layers. Six spin valves, sputtered at different temperatures, three with thin ~3 nm! and three with thick ~24 and 30 nm! NiFe layers, were studied. All of t...
Burkholderia cenocepacia is a member of the B. cepacia complex (Bcc), a group of opportunistic bacteria that infect the airways of patients with cystic fibrosis (CF) and are extraordinarily resistant to almost all clinically useful antibiotics. Infections in CF patients with Bcc bacteria generally lead to a more rapid decline in lung function, and in some cases to the 'cepacia syndrome', a virt...
Basal cell carcinoma (BCC) is the most common neoplasm in the Caucasian population. Only a fraction of BCC exhibits pigmentation. Lack of melanocyte colonization has been suggested to be due to p53-inactivating mutations in the BCC cells interfering with the p53-proopiomelanocortin pathway and the production of alpha melanocyte-stimulating hormone in the tumor. To evaluate this, we determined t...
