چکیده
To provide public service broadcasting on digital satellite, digital terrestrial and digital cable the BBC has been working in partnership with other UK broadcasters to develop widescreen digital television services ready for launch on DSAT and DTT in 1998 and subsequently on DCABLE. As the BBC is both a National and a regional broadcaster, the complexity and economics of distributing new services to a large number of regional studio premises has required a fresh approach. This paper describes the architecture for coding and distributing BBC National and Regional services via an ATM-based network to feed these delivery media, outlines some of the design considerations and records progress to date.

Molecular heterogeneity of inflammatory breast cancer: a hyperproliferative phenotype.
PURPOSE Inflammatory breast cancer (IBC) is associated with very poor prognosis. The aims of this study are (a) to prospectively identify differential gene expression patterns associated with IBC and (b) to confirm these pathways using tissue arrays. EXPERIMENTAL DESIGN For gene expression analysis, IBC (n=14) was clinically defined as rapid-onset cancer associated with erythema and skin chan...

متن کاملInflammatory Breast Cancer: High Incidence of Detection of Mixed Human Cytomegalovirus Genotypes Associated with Disease Pathogenesis
Inflammatory breast cancer (IBC) is a highly metastatic, aggressive, and fatal form of breast cancer. Patients presenting with IBC are characterized by a high number of axillary lymph node metastases. Recently, we found that IBC carcinoma tissues contain significantly higher levels of human cytomegalovirus (HCMV) DNA compared to other breast cancer tissues that may regulate cell signaling pathw...
متن کاملLong-Term Outcome of Inflammatory Breast Cancer Compared to Non-Inflammatory Breast Cancer in the Setting of High-Dose Chemotherapy with Autologous Hematopoietic Cell Transplantation
Introduction: Inflammatory breast cancer (IBC) is a rare aggressive form of breast cancer. It is well known that the long-term survival and progression-free survival of IBC are worse than that of non-IBC. We report the long term outcomes of patients with IBC and non-IBC who had undergone high-dose chemotherapy (HDC) with autologous hematopoietic cell transplantation (AHCT). Methods: All 3387 pa...
متن کاملA stromal gene signature associated with inflammatory breast cancer.
The factors that determine whether a breast carcinoma will develop into inflammatory breast cancer (IBC) remain poorly understood. Recent evidence indicates that the tumor stroma influences cancer phenotypes. We tested the hypotheses that the gene expression signature of the tumor stroma is a distinctive feature of IBC. We used laser capture microdissection to obtain enriched populations of tum...
متن کاملCharacterization and Targeting of Platelet-Derived Growth Factor Receptor alpha (PDGFRA) in Inflammatory Breast Cancer (IBC)1
PURPOSE Inflammatory breast cancer (IBC) is arguably the deadliest form of breast cancer due to its rapid onset and highly invasive nature. IBC carries 5- and 10-year disease-free survival rates of ~45% and <20%, respectively. Multiple studies demonstrate that in comparison with conventional breast cancer, IBC has a unique molecular identity. Here, we have identified platelet-derived growth fac...
