Allogeneic Stem Cell Transplant Versus Tandem High-Dose Melphalan for Front-Line Treatment of Deletion 13q14 Myeloma – An Interim Analysis of the Ger…

2009

Abstract Abstract 51 Background Allogeneic stem cell transplantation (allo SCT), a treatment modality based on transfer of immunocompetent donor lymphocytes offers curative potential to subjects with a variety of hematological cancers. In multiple myeloma (MM), high-dose melphalan followed by autologous stem cell transplantation (auto SCT) is adopted as a standard of care. However, it remains palliative since virtually all patients (pts) relapse and renders allo SCT an option of interest. Deletion of chromosome 13q14 (13q-) in MM has been shown to negatively impact prognosis. Therefore, improvement of therapy for 13q- pts is highly desirable. Patients and methods A prospective two-arm multi…

Comparative analysis of mast cell count in normal oral mucosa and oral pyogenic granuloma

2011

Introduction: Mast cells are large granular cells that arise from a multipotent CD 34+ precursor in the bone marrow normally distributed throughout connective tissues. The most common method to study role of mast cells in any altered condition involves their identification and quantification in that condition and compare the values with that of the normal average count or number of mast cells. The present study was thus, undertaken to identify as well as quantify mast cells in oral pyogenic granuloma and compare it with the average count of mast cells in normal oral mucosa, thus aiming to assess the changes in count of mast cells in oral pyogenic granuloma. Materials and Methods: Ten cases …

A quest for initiating cells of head and neck cancer and their treatment.

2010

The biology of head and neck squamous cell carcinomas (HNSCC) and other cancers have been related to cancer stem-like cells (CSC). Specific markers, which vary considerably depending on tumor type or tissue of origin, characterize CSC. CSC are cancer initiating, sustaining and mostly quiescent. Compared to bulk tumors, CSC are less sensitive to chemo- and radiotherapy and may have low immunogenicity. Therapeutic targeting of CSC may improve clinical outcome. HNSCC has two main etiologies: human papillomavirus, a virus infecting epithelial stem cells, and tobacco and alcohol abuse. Here, current knowledge of HNSCC-CSC biology is reviewed and parallels to CSC of other origin are drawn where n…

CD38-Specific Biparatopic Heavy Chain Antibodies Display Potent Complement-Dependent Cytotoxicity Against Multiple Myeloma Cells

2018

CD38 is overexpressed by multiple myeloma cells and has emerged as a target for therapeutic antibodies. Nanobodies are soluble single domain antibody fragments derived from the VHH variable domain of heavy chain antibodies naturally occurring in camelids. We previously identified distinct llama nanobodies that recognize three non-overlapping epitopes of the extracellular domain of CD38. Here, we fused these VHH domains to the hinge, CH2, and CH3 domains of human IgG1, yielding highly soluble chimeric llama/human heavy chain antibodies (hcAbs). We analyzed the capacity of these hcAbs to mediate complement-dependent cytotoxicity (CDC) to CD38-expressing human multiple myeloma and Burkitt lymp…

Trends in survival of multiple myeloma patients in Germany and the United States in the first decade of the 21st century

2015

Multiple myeloma is a chronic, incurable but highly treatable neoplasm. Recent population-based studies have shown improvements in survival for patients diagnosed in the early 21st century. Here, we examine trends in survival for patients diagnosed with multiple myeloma in Germany and the United States (US) between 2002 and 2010. Data were extracted from 11 population-based cancer registries in Germany and from the Surveillance, Epidemiology and End Results database in the US. Myeloma patients aged 15-74 years with diagnosis and follow-up between 1997 and 2010 from Germany and the US were included. Period analysis was employed to assess trends in 5-year relative survival in Germany and the …

Challenges in joint place branding in rural regions

2013

The purpose of this article is to explore joint place branding in rural regions, focusing on cooperation between the various stakeholders involved and on the salient features of rural regions that are used in the place branding process. Branding is conceptualized as a social process where brand value is co-created by the stakeholders. Place branding is seen as a participative process, bringing stakeholders together with the aim to strengthen the identity of the place. The fundamental question is how to build long-term commitment in a group of key stakeholders. Many sources discuss place branding for large cities, but rural regions have received little attention. The process of place brandin…

Proteinase-3 mRNA expressed by glomerular epithelial cells correlates with crescent formation in Wegener's granulomatosis

2000

Proteinase-3 mRNA expressed by glomerular epithelial cells correlates with crescent formation in Wegener's granulomatosis. Background Wegener's granulomatosis (WG) is characterized by systemic vasculitis with crescentic glomerulonephritis (CGN) and circulating autoantibodies directed against neutrophil cytoplasmic antigens (ANCA). Proteinase 3 (PR-3), a neutral serine proteinase in neutrophils implicated in the growth control of myeloid cells, has been identified as the target antigen for ANCA in WG. Since the kidneys are frequently involved in WG, we studied the in situ expression of PR-3 by renal parenchymal cells. Methods We assessed the expression of PR-3 in kidney biopsies of 15 patien…

Génesis y resolución de conflictos relacionados con la instalación de mezquitas y oratorios: el caso del oratorio de Singuerlín (Santa Coloma de Gram…

2017

Durante los últimos años, se han sucedido, en diferentes territorios del Estado español, los conflictos relacionados con la instalación de mezquitas y oratorios destinados a la práctica del culto musulmán. Este artículo analiza uno de los conflictos más intensos, el desatado en 2004 ante el intento de apertura del oratorio del barrio de Singuerlín en Santa Coloma de Gramenet. Se estudia su raíz, su evolución y el papel que jugó la mediación intercultural en su gestión. A partir de las entrevistas en profundidad efectuadas con los actores implicados, varios años después, se analizan los elementos estructurales del conflicto y se plantea una reflexión acerca de la forma en la que se ha ido co…

Human kininogens interact with M protein, a bacterial surface protein and virulence determinant.

1995

Streptococcus pyogenes, the most significant streptococcal species in clinical medicine, expresses surface proteins with affinity for several human plasma proteins. Here we report that kininogens, the precursors to the vasoactive kinins, bind to the surface of S. pyogenes. M protein, a surface molecule and a major virulence factor-in these bacteria, occurs in > 80 different serotypes. Among 49 strains of S. pyogenes, all of different M serotypes, 41 bound radiolabelled kininogens, whereas 6 M protein-negative mutant strains showed no affinity. M protein of most serotypes bind fibrinogen, and among the 55 strains tested, binding of kininogens was closely correlated to fibrinogen bindi…
