Immunological Deregulation in Classic Hodgkin Lymphoma  

PubMed Central

Classic Hodgkin Lymphoma (cHL) has a unique histology since only a few neoplastic cells are surrounded by inflammatory accessory cells that in the last years have emerged as crucial players in sustaining the course of disease. In addition, recent studies suggest that the abnormal activity of these inflammatory cells (such as deregulation in regulatory T cells signaling, expansion of myeloid derived suppressor cells, HLA-G signaling and natural killer cells dysfunction) may have prognostic significance. This review is focused on summarizing recent advanced in immunological defects in cHL with translational implications. PMID:24959336

Tumor-Associated Macrophages and Survival in Classic Hodgkin's Lymphoma  

PubMed Central

Background Despite advances in treatments for Hodgkin's lymphoma, about 20% of patients still die from progressive disease. Current prognostic models predict the outcome of treatment with imperfect accuracy, and clinically relevant biomarkers have not been established to improve on the International Prognostic Score. Methods Using gene-expression profiling, we analyzed 130 frozen samples obtained from patients with classic Hodgkin's lymphoma during diagnostic lymph-node biopsy to determine which cellular signatures were correlated with treatment outcome. We confirmed our findings in an independent cohort of 166 patients, using immunohistochemical analysis. Results Gene-expression profiling identified a gene signature of tumor-associated macrophages that was significantly associated with primary treatment failure (P = 0.02). In an independent cohort of patients, we found that an increased number of CD68+ macrophages was correlated with a shortened progression-free survival (P = 0.03) and with an increased likelihood of relapse after autologous hematopoietic stem-cell transplantation (P = 0.008), resulting in shortened disease-specific survival (P = 0.003). In multivariate analysis, this adverse prognostic factor outperformed the International Prognostic Score for disease-specific survival (P = 0.003 vs. P = 0.03). The absence of an elevated number of CD68+ cells in patients with limited-stage disease defined a subgroup of patients with a long-term disease-specific survival of 100% with the use of current treatment strategies. Conclusions An increased number of tumor-associated macrophages was strongly associated with shortened survival in patients with classic Hodgkin's lymphoma and provides a new biomarker for risk stratification.

Classical Hodgkin lymphoma, lymphocyte depleted type: clinicopathological analysis and prognostic comparison with other types of classical Hodgkin lymphoma.  

PubMed

The lymphocyte-depleted type (LD) is a morphological subtype of classical Hodgkin lymphoma (CHL), but its rarity and heterogeneous morphological character makes a definite clinicopathological identification difficult. To characterize this disease, LD cases were compared with other types of CHL. From 1982 to 2006, we collected 310 CHL cases. Among them, 29 cases were diagnosed as LD. We could additionally analyze clinical data of 157 CHL cases (including 28 LD cases) and the immunophenotype of 150 CHL cases (including 28 LD cases). We compared clinicopathological data between LD cases and other types of CHL cases and determined prognostic factors by univariate and multivariate analysis. LD showed a more progressive disease stage (stage 3/4, 64%) than other types of CHL (stage 3/4, 30%; P<0.001), more frequent B symptoms (89% vs. 40%; P<0.001) and extranodal invasion (50% vs. 11%; P<0.001), older age (median: 66 vs. 33; P<0.001), higher serum soluble interleukin 2 receptor levels (median: 8240U/ml vs. 1705U/ml; P<0.001), and much poorer prognosis regardless of the international prognostic score (IPS) (five-year overall survival: 29% vs. 86%; P<0.001). The morphological subtype of LD represented an independent prognostic factor as did age and IPS by multivariate analysis. Immunohistochemistry showed that the characteristics of Hodgkin and Reed-Sternberg (HRS) cells of LD are basically not different from those of other types of CHL in terms of CD30, CD15, and chemokine receptors, except for high-level EB-virus infection (72% vs. 41%; P=0.002). LD should be distinguished from other types of classical Hodgkin lymphoma because of its definitive clinicopathological characters. PMID:23478005

A single slide multiplex assay for the evaluation of classical Hodgkin lymphoma.  

PubMed

Classical Hodgkin lymphoma can be diagnosed with confidence in the majority of cases, but there is a significant subset that remains a diagnostic challenge. The authors have investigated the utility of a novel hyperplexing technology, MultiOmyx™, which may be applied to stain with >60 antibodies on single tissue sections from formalin-fixed paraffin-embedded tissue as an aid to the diagnosis of classical Hodgkin lymphoma. The multiplexing protocol included CD30, CD15, PAX-5, CD20, CD79a, CD45, BOB.1, OCT-2, and CD3 antibodies. The technology showed a high degree of sensitivity, specificity, and precision. Comparison studies with routine hematoxylin and eosin and immunohistochemical assessment of hematopathology cases in which classical Hodgkin lymphoma was included in the differential diagnosis showed concordance in 54 of 56 cases, with the 2 discordant cases illustrating the potential of this multiplexed immunofluorescence technology to improve on traditional immunohistochemistry for classical Hodgkin lymphoma diagnosis. This technology is practical for routine diagnosis and may be particularly useful in cases in which the sample size is limited, few Hodgkin-like cells are present, or in CD30-positive lymphoma cases with difficult morphology. MultiOmyx may potentially benefit other areas of research and diagnostic pathology. PMID:24854113

Matrix Metalloproteinase-9 Expression by Hodgkin-Reed-Sternberg Cells Is Associated with Reduced Overall Survival in Young Adult Patients with Classical Hodgkin Lymphoma  

PubMed Central

Previous studies have investigated the prognostic relevance of MMP9 in classical Hodgkin lymphoma (cHL), with negative results. However, we have found that MMP9 immunoistochemical expression by Hodgkin-Reed-Sternberg cells is associated with reduced overall survival in a subset of young adult Brazilian patients diagnosed with cHL. Additionally, we have observed that MMP9 expression by neoplastic cells in cHL is associated with EBV positivity. These results may support a rational basis for additional studies on the role of this metalloproteinase as a target for therapy in classical Hodgkin lymphoma. PMID:24086377

B-cell lymphoma, unclassifiable, with features intermediate between diffuse large B-cell lymphoma and classical Hodgkin lymphoma without mediastinal disease: mimicking nodular sclerosis classical Hodgkin lymphoma.  

PubMed

B-cell lymphoma, unclassifiable, with features intermediate between diffuse large B-cell lymphoma and classical Hodgkin lymphoma (BCLu-DLBCL/CHL), also known as gray-zone lymphoma, has overlapping clinical and biological characteristics of both diffuse large B-cell lymphoma and classical Hodgkin lymphoma (CHL). These lymphomas are typically associated with mediastinal disease, and extranodal involvement is rare. In the present report, we describe a case of a 78-year-old woman with BCLu-DLBCL/CHL found to have extranodal lesions and no evidence of mediastinal disease. Although biopsy specimens were histologically similar to nodular sclerosis CHL, the tumor cells were positive for CD30 and mature B-cell markers, such as CD20, CD79a, PAX5, BOB.1, and OCT-2, but negative for CD15. Furthermore, the patient had extranodal lesions and an increased level of soluble IL-2 receptor. These findings are unusual in CHL. Therefore, we diagnosed the patient with BCLu-DLBCL/CHL. She received adriamycin, bleomycin, vincristine, and dacarbazine therapy and exhibited partial response. Some cases without mediastinal disease, such as our case, have been reported; however, these cases are rare and further studies are required. PMID:23512149

Nodular sclerosing classical Hodgkin lymphoma masquerading as acute suppurative-necrotizing lymphadenitis.  

PubMed

The diagnosis of nodular sclerosing classical Hodgkin lymphoma (NSCHL) by fine-needle aspiration (FNA) biopsy has historically been a diagnostic challenge due to the usual paucicellularity of the specimen. This case report, and other previously published reports, suggests that there is another facet to the potentially challenging diagnosis of this particular variant of Hodgkin lymphoma (HL): the presence of suppurative-necrotizing changes mimicking an infectious etiology. The patient presented here underwent FNA biopsy of an acutely enlarged supraclavicular lymph node and cytologic smears showed marked acute inflammation in a background of necrosis. A diagnosis of infectious suppurative lymphadenitis was made at that time. After a negative infectious work-up with infectious disease consultation, an excisional biopsy was performed and the patient was definitively diagnosed with NSCHL. The presence of neoplastic Hodgkin and Reed-Sternberg cells in the purulent exudate was minimal and only appropriately identified after retrospective review. This particular subtype of classical HL represents a potential pitfall in FNA biopsy cytology. Consequently, the cytopathologist and surgeon should always consider this entity in the differential diagnosis of a suppurative, lymphadenitis-like aspirate, and pursue repeat FNA or an excisional biopsy if there is any clinical index of suspicion.

Clinicopathological analysis of mediastinal large B-cell lymphoma and classical Hodgkin lymphoma of the mediastinum.  

PubMed

Primary mediastinal (thymic) large B-cell lymphoma (PMLBCL) and nodular sclerosing classical Hodgkin lymphoma (NSCHL) are the major histological types of lymphoma affecting the mediastinum. We reviewed 27 patients with PMLBCL and 14 patients with NSCHL. A poor performance status, high serum lactate dehydrogenase level and strong positivity for PAX5 were all significantly more common in patients with PMLBCL than in those with NSCHL. Severe fibrosis was frequent in NSCHL, but not in PMLBCL. PDL1 was expressed by 11/25 PMLBCLs (44.0%) vs. 1/9 NSCHLs (11.1%). Expression of BCL6 was significantly more frequent in PDL1-positive PMLBCL than in PDL1-negative PMLBCL, but there were no clinical differences between these two groups. Two patients with PMLBCL with a poor prognosis had CD20(-), CD79a(+), CD15(-), and CD30(-), possibly representing a subtype of mediastinal gray zone lymphoma. PMID:23020783

Classical Hodgkin lymphoma arising in the setting of iatrogenic immunodeficiency: a clinicopathologic study of 10 cases.  

PubMed

Iatrogenic immunodeficiency-associated lymphoproliferative disorders are rare. A small subset of these lesions resembles classical Hodgkin lymphoma (CHL), but there are few data in the literature about these lesions. We describe 10 patients with autoimmune diseases treated with immunomodulator therapeutic agents who developed CHL. The autoimmune diseases included rheumatoid arthritis (n=5), systemic lupus erythematosus (n=2), dermatomyositis (n=1), autoimmune hepatitis (n=1), and Crohn disease (n=1), and the immunomodulatory therapies were methotrexate, azathioprine, tumor necrosis factor-? inhibitors, and thalidomide alone or in various combinations. The study group included 9 women and 1 man with a median age of 50 years (range, 25 to 77 y). The histologic features supported CHL in all cases with Reed-Sternberg (RS) and Hodgkin (H) cells in an inflammatory cell background, although the neoplasm could only be subclassified in 3 patients: 2 nodular sclerosis and 1 mixed cellularity. Immunohistochemical analysis supported the diagnosis of CHL. In all cases the RS-H cells were CD30. Nine of 10 cases were CD15, whereas CD20 was expressed variably in 4/10 cases. CD45/LCA was negative in 8 cases assessed. In situ hybridization for Epstein-Barr virus-encoded RNA was positive in the RS-H cells in 8/10 cases. The microenvironment of these lesions depicted a predominance of T-regulatory cells and M2 histiocytes. Clinical follow-up data were available for 7 patients, with a median posttreatment period of 27 months (range, 12 mo to 7 y). In all 7 patients immunomodulatory drug therapy was discontinued, and chemotherapy for CHL was administered; 2 patients also received local radiation. All 7 patients achieved complete remission and are alive. We conclude that iatrogenic immunodeficiency-associated CHL is highly associated with Epstein-Barr virus infection, and patients usually have a good outcome after discontinuation of immunomodulatory agents and chemotherapy for CHL.

Germ-Line Transmitted, Chromosomally Integrated HHV-6 and Classical Hodgkin Lymphoma  

PubMed Central

A unique feature of both human herpesvirus 6A and B (HHV-6A and B) among human herpesviruses is their ability to integrate into chromosomal telomeres. In some individuals integrated viral genomes are present in the germ-line and result in the vertical transmission of HHV-6; however, little is known about the disease associations of germ-line transmitted, chromosomally integrated HHV-6 (ciHHV-6). Recent publications suggest that HHV-6 is associated with classical Hodgkin lymphoma (cHL). Here we examine the prevalence of ciHHV-6 in 936 cases of cHL and 563 controls by screening with a duplex TaqMan assay and confirming with droplet digital PCR. ciHHV-6 was detected in 10/563 (1.8%) controls and in all but one individual the virus was HHV-6B. Amongst cases 16/936 (1.7%) harboured ciHHV-6, thus demonstrating no association between ciHHV-6 and risk of cHL. PMID:25384040

Galectin-1 serum levels reflect tumor burden and adverse clinical features in classical Hodgkin lymphoma.  

PubMed

Galectin-1 (Gal1) is a member of a highly conserved family of carbohydrate-binding proteins. It modulates innate and adaptive immune responses and fosters tumor-immune escape. Hodgkin lymphoma (HL) Reed-Sternberg cells overexpress and secrete Gal1, which selectively kills T helper (Th)1 and Th17 cells and cytotoxic T cells and promotes the immunosuppressive Th2/regulatory T-cell-predominant HL microenvironment. We developed a sandwich enzyme-linked immunosorbent assay and assessed serum Gal1 levels in 293 newly diagnosed, previously untreated patients with classical HL (cHL) enrolled in 3 risk-adapted clinical trials. Serum Gal1 levels were significantly higher in patients with cHL than in normal controls (P < .0001). Gal1 serum levels also increased with Ann Arbor stage (P = .012), areas of nodal involvement (P < .0001), and the International Prognostic Score (2-7, P = .019). We conclude that Gal1 serum levels are significantly associated with tumor burden and related clinical features in newly diagnosed cHL patients. PMID:23444403

Hodgkin-Reed-Sternberg Cells in Classical Hodgkin Lymphoma Show Alterations of Genes Encoding the NADPH Oxidase Complex and Impaired Reactive Oxygen Species Synthesis Capacity  

PubMed Central

The membrane bound NADPH oxidase involved in the synthesis of reactive oxygen species (ROS) is a multi-protein enzyme encoded by CYBA, CYBB, NCF1, NCF2 and NCF4 genes. Growing evidence suggests a role of ROS in the modulation of signaling pathways of non-phagocytic cells, including differentiation and proliferation of B-cell progenitors. Transcriptional downregulation of the CYBB gene has been previously reported in cell lines of the B-cell derived classical Hodgkin lymphoma (cHL). Thus, we explored functional consequences of CYBB downregulation on the NADPH complex. Using flow cytometry to detect and quantify superoxide anion synthesis in cHL cell lines we identified recurrent loss of superoxide anion production in all stimulated cHL cell lines in contrast to stimulated non-Hodgkin lymphoma cell lines. As CYBB loss proved to exert a deleterious effect on the NADPH oxidase complex in cHL cell lines, we analyzed the CYBB locus in Hodgkin and Reed-Sternberg (HRS) cells of primary cHL biopsies by in situ hybridisation and identified recurrent deletions of the gene in 8/18 cases. Immunohistochemical analysis to 14 of these cases revealed a complete lack of detectable CYBB protein expression in all HRS cells in all cases studied. Moreover, by microarray profiling of cHL cell lines we identified additional alterations of NADPH oxidase genes including CYBA copy number loss in 3/7 cell lines and a significant downregulation of the NCF1 transcription (p=0.006) compared to normal B-cell subsets. Besides, NCF1 protein was significantly downregulated (p<0.005) in cHL compared to other lymphoma cell lines. Together this findings show recurrent alterations of the NADPH oxidase encoding genes that result in functional inactivation of the enzyme and reduced production of superoxide anion in cHL.

Refractory Classical Hodgkin Lymphoma Presenting with Atypical Cutaneous Involvement and Diagnosis of ZZ Phenotype Alpha-1 Antitrypsin Deficiency  

PubMed Central

Cutaneous Hodgkin lymphoma is a rare condition. Specific neoplastic involvement can be primary (confined to the skin) or secondary to systemic involvement (metastatic). Cutaneous involvement by HL usually occurs late in the course and is associated with poor prognosis; however in some cases it can exhibit indolent behavior. Skin involvement with nonspecific cutaneous findings may represent a paraneoplastic syndrome. We describe a case of 46-year-old white male patient presented with rash and lymphadenopathy which led to the diagnosis of stage IVE mixed cellularity classical Hodgkin lymphoma with skin involvement. His disease was refractory to multiple lines of chemotherapy including (1) AVD (doxorubicin/bleomycin/dacarbazine), (2) brentuximab, and (3) bendamustine, he later achieved complete remission with (4) GCD (gemcitabine/carboplatin/dexamethasone) salvage regimen. Bleomycin was not given secondary to poor pulmonary function tests. His treatment was complicated after AVD with multiple pneumothoraces which unmasked the diagnosis of ZZ phenotype alpha-1 antitrypsin (ATT) deficiency. Simultaneous existence of Hodgkin lymphoma and ATT is rarely reported. PMID:24955265

Composite diffuse large B-cell lymphoma and classical Hodgkin's lymphoma of the stomach: Case report and literature review  

PubMed Central

The combination of classical Hodgkin’s lymphoma (cHL) and non-Hodgkin lymphoma coexisting in the same patient is not common, especially in one extranodal location. Here we present a rare case of composite diffuse large B-cell lymphoma (DLBCL) and cHL occurring simultaneously in the stomach of a 53-year-old female who presented with upper abdominal discomfort and gas pain. Surgery was performed and the disease was diagnosed pathologically as composite lymphoma of DLBCL and cHL using hematoxylin-eosin and immunohistochemical staining. Epstein-Barr virus (EBV) infection was not detected by in situ hybridization for EBV-encoded RNA or immunohistochemistry for EBV latent membrane protein-1. Polymerase chain reaction analysis from the two distinct components of the tumor demonstrated clonal immunoglobulin ? light chain gene rearrangements. The patient died approximately 11 mo after diagnosis in spite of receiving eight courses of the CHOP and two courses of the rituximab-CHOP (RCHOP) chemotherapy regimen. This case report showed that the two distinct components, DLBCL and cHL, appeared to originate from the same clonal progenitor cell, and that EBV infection was not essential for transformation during the course of tumorigenesis.

c-JUN N-terminal kinase (JNK) is activated and contributes to tumor cell proliferation in classical Hodgkin lymphoma.  

PubMed

c-JUN N-terminal Kinase (JNK) is activated/phosphorylated by upstream MAPK kinases (MKK), and, in turn, phosphorylates and activates its major substrate c-JUN, a member of the activator protein-1 (AP-1) transcription factors. c-JUN is overexpressed and activated in Hodgkin and Reed Sternberg cells (HRS) of classical Hodgkin lymphoma (cHL), however, the mechanism of its activation remains unknown. JNK activation was immunohistochemically assessed in 60 cases of HL and in a control group of 151 B-cell non-Hodgkin lymphomas. The biologic effects of JNK activation in cultured HRS cells were investigated using colony formation, cell growth and viability assays and cell cycle analysis by flow cytometry. Western blotting was used to assess protein levels. p-JNK was expressed in 90% of HL, 83% of Burkitt lymphomas, 28% of mantle cell lymphomas, 23% of diffuse large B-cell lymphomas, 19% of follicular lymphomas, and 18% of extranodal marginal zone lymphomas of MALT type. None of the 48 cases of chronic lymphocytic leukemia/small lymphocytic lymphoma and 18 cases of plasma cell myeloma showed JNK phosphorylation (P < 001, Kruskall-Wallis test). Pharmacological inhibition of JNK activity in cultured HRS cells resulted in a significant decrease of cell growth, which was associated with cell cycle arrest at the G2/M phase. The cell cycle effects were linked to deactivation of c-JUN and upregulation of its known target, the cyclin-dependent kinase inhibitor p21. JNK is highly activated in HRS cells, and may contribute to uncontrolled cell cycle progression and proliferation of tumor cells in cHL. PMID:24457077

Mapping of transcription factor motifs in active chromatin identifies IRF5 as key regulator in classical Hodgkin lymphoma  

PubMed Central

Deregulated transcription factor (TF) activities are commonly observed in hematopoietic malignancies. Understanding tumorigenesis therefore requires determining the function and hierarchical role of individual TFs. To identify TFs central to lymphomagenesis, we identified lymphoma type-specific accessible chromatin by global mapping of DNaseI hypersensitive sites and analyzed enriched TF-binding motifs in these regions. Applying this unbiased approach to classical Hodgkin lymphoma (HL), a common B-cell–derived lymphoma with a complex pattern of deregulated TFs, we discovered interferon regulatory factor (IRF) sites among the top enriched motifs. High-level expression of the proinflammatory TF IRF5 was specific to HL cells and crucial for their survival. Furthermore, IRF5 initiated a regulatory cascade in human non-Hodgkin B-cell lines and primary murine B cells by inducing the TF AP-1 and cooperating with NF-?B to activate essential characteristic features of HL. Our strategy efficiently identified a lymphoma type-specific key regulator and uncovered a tumor promoting role of IRF5. PMID:25288773

Reed-Sternberg cell-derived lymphotoxin-? activates endothelial cells to enhance T-cell recruitment in classical Hodgkin lymphoma.  

PubMed

It is known that cells within the inflammatory background in classical Hodgkin lymphoma (cHL) provide signals essential for the continual survival of the neoplastic Hodgkin and Reed-Sternberg (HRS) cells. However, the mechanisms underlying the recruitment of this inflammatory infiltrate into the involved lymph nodes are less well understood. In this study, we show in vitro that HRS cells secrete lymphotoxin-? (LT?) which acts on endothelial cells to upregulate the expression of adhesion molecules that are important for T cell recruitment. LT? also enhances the expression of hyaluronan which preferentially contributes to the recruitment of CD4(+) CD45RA(+) naïve T cells under in vitro defined flow conditions. Enhanced expression of LT? in HRS cells and tissue stroma; and hyaluronan on endothelial cells are readily detected in involved lymph nodes from cHL patients. Our study also shows that although NF-?B and AP-1 are involved, the cyclooxygenase (COX) pathway is the dominant regulator of LT? production in HRS cells. Using pharmacological inhibitors, our data suggest that activity of COX1, but not of COX2, directly regulates the expression of nuclear c-Fos in HRS cells. Our findings suggest that HRS cell-derived LT? is an important mediator that contributes to T cell recruitment into lesional lymph nodes in cHL. PMID:25139349

B cells in classical Hodgkin lymphoma are important actors rather than bystanders in the local immune reaction.  

PubMed

Recent studies, largely focusing on cellular immunity, have demonstrated that the composition of the abundant inflammatory background of Hodgkin lymphoma may affect outcome. This investigation aimed to characterize the potential role of infiltrating B cells and follicular dendritic cell networks in classical Hodgkin lymphoma (cHL) to better assess the role of components of humoral immunity. One hundred two cHL biopsies were investigated by immunohistochemistry with antibodies specific for CD20, CD138, activation-induced cytidine deaminase, and CD21 to characterize B cell distribution and follicular structures. To further subclassify B cells, analyses of tissue microarrays were performed investigating the expression of Mum1, Bcl6, IgD, IgG, IgG4, IgM, T-bet, CD38, CD5, and CD10. For evaluation a computer assisted quantification method was compared with a scoring system. Survival analysis and correlation analysis were performed. The B cell infiltrate was dominated by CD20+ B cells, followed by plasma cells, whereas only few AID+ cells were observed. High numbers of CD21+ follicular dendritic cell networks, CD20+ B cells, IgM+ cells, CD20+ aggregates, and Bcl6+ cells were associated with a better outcome of cHL patients, whereas Pax5+/CD38+ cells had an adverse prognostic impact. Other parameters showed no influence on survival. Our findings suggest that a complex network of B cells is present in the microenvironment of cHL and that B cells might actively contribute to a local anti- as well as pro-tumoral immune response. This indicates that the network of B cells in tumors is probably just as diverse as the T cellular infiltrate and probably functionally as heterogenous. PMID:24029709

BOB.1-positive Classical Hodgkin's Lymphoma Carries Hypermethylation of Its Promoter as Epigenetic Marker of Gene-silencing Memory  

PubMed Central

Analysis of archival formalin-fixed, paraffin-embedded (FFPE) pathological specimens of three case of Epstein-Barr virus (EBV)-positive diffuse large B-cell lymphoma (DLBCL) and three cases of classical Hodgkin lymphoma (CHL) revealed that hypermethylation of the BOB.1 gene promoter was exclusively observed in CHL. A discrepancy was observed, however, between the methylation status of the BOB.1 gene promoter and its expression in the EBV-positive mixed cellular CHL (MCCHL). Since MCCHL lacks the typical B-cell phenotype even in the presence of abundant BOB.1 transcription factors, functional activity of BOB.1 may be lost or reduced by a mechanism other than epigenetic gene silencing. When some tumor-suppressor gene products have lost their biological function, impact or significance of derepression of such genes may be little. Therefore, when interpreting immunohistochemical results for diagnostic or research purposes, it must be borne in mind that apparent positive immunostaining can merely be the result of chromatin remodeling and that such transient expression often has little functional significance. Any apparent positive immunohistochemical result needs to be interpreted carefully with the help of the hypermethylation status as a molecular marker of gene silencing memory. PMID:25320409

CD137 Is Expressed in Follicular Dendritic Cell Tumors and in Classical Hodgkin and T-Cell Lymphomas  

PubMed Central

CD137 (also known as 4-1BB and TNFRSF9) is a member of the tumor necrosis factor receptor superfamily. Originally identified as a costimulatory molecule expressed by activated T cells and NK cells, CD137 is also expressed by follicular dendritic cells, monocytes, mast cells, granulocytes, and endothelial cells. Anti-CD137 immunotherapy has recently shown promise as a treatment for solid tumors and lymphoid malignancies in preclinical models. We defined the expression of CD137 protein in both normal and neoplastic hematolymphoid tissue. CD137 protein is expressed by follicular dendritic cells in the germinal center and scattered paracortical T cells, but not by normal germinal-center B cells, bone marrow progenitor cells, or maturing thymocytes. CD137 protein is expressed by a select group of hematolymphoid tumors, including classical Hodgkin lymphoma, T-cell and NK/T-cell lymphomas, and follicular dendritic cells neoplasms. CD137 is a novel diagnostic marker of these tumors and suggests a possible target for tumor-directed antibody therapy. PMID:22901750

Concurrent malignant melanoma and cutaneous involvement by classical hodgkin lymphoma (CHL) in a 63 year-old man  

PubMed Central

Abstract Classical Hodgkin lymphoma (CHL) is a lymphoproliferative disorder that has a bimodal age distribution, affecting young and elderly individuals, and is curable in more than 90% of patients. Here we report the coexistence of cutaneous CHL and malignant melanoma as the presentation of papules and a plaque, in an individual with remote history of systemic CHL. One of the biopsies showed a mononuclear cell infiltrate with Reed-Sternberg (RS) like cells that were positive for CD30 and CD15, but negative for CD45. A second concurrent biopsy showed an atypical melanocytic proliferation with significant pagetoid spreading and diffuse Melan-A staining. Based on morphology alone, it is almost impossible to distinguish CHL from other primary cutaneous lymphoproliferative disorders, such as CD30+ lymphoproliferative disorder (lymphomatoid papulosis (LyP) and primary cutaneous anaplastic large-cell lymphoma), or even tumor stage mycosis fungoides when the epidermotropism is minimal. Additionally, bizarre melanocytic cells can also appear similar to RS cells. Our case illustrates the first case report of malignant melanoma and CHL in a patient presenting simultaneously.

Classical Hodgkin's lymphoma: the Lymphoma Study Association guidelines for relapsed and refractory adult patients eligible for transplant  

PubMed Central

The Hodgkin’s Lymphoma Committee of the Lymphoma Study Association (LYSA) gathered in 2012 to prepare guidelines on the management of transplant-eligible patients with relapsing or refractory Hodgkin’s lymphoma. The working group is made up of a multidisciplinary panel of experts with a significant background in Hodgkin’s lymphoma. Each member of the panel of experts provided an interpretation of the evidence and a systematic approach to obtain consensus was used. Grades of recommendation were not required since levels of evidence are mainly based on phase II trials or standard practice. Data arising from randomized trials are emphasized. The final version was endorsed by the scientific council of the LYSA. The expert panel recommends a risk-adapted strategy (conventional treatment, or single/double transplantation and/or radiotherapy) based on three risk factors at progression (primary refractory disease, remission duration < 1 year, stage III/IV), and an early evaluation of salvage chemosensitivity, including 18fluorodeoxy glucose-positron emission tomography interpreted according to the Deauville scoring system. Most relapsed or refractory Hodgkin’s lymphoma patients chemosensitive to salvage should receive high-dose therapy and autologous stem-cell transplantation as standard. Efforts should be made to increase the proportion of chemosensitive patients by alternating non-cross-resistant chemotherapy lines or exploring the role of novel drugs. PMID:23904236

A Web 2.0 Personal Learning Environment for Classical Chinese Poetry  

NASA Astrophysics Data System (ADS)

Classical Chinese Poetry (CCP) is a valuable but almost locked treasure chest of human wisdom and civilization since 2000 years. With the advent of the Web 2.0 a renaissance of CCP is possible even outside Chinese-speaking communities world-wide. With mobile technologies and educational games we can address new learning communities for CCP and open the chest again. In this paper, we introduce a Web 2.0 personal learning environment for CCP. We have developed a generic and interoperable data model for CCP we utilize not only for mobile learning scenarios but also for educational gaming with different levels of difficulty. Learners are empowered to learn Chinese poetry, language, history, and culture. This research work shows how modern information technologies assist users to diffuse knowledge across the borderlines of communities and societies.

Lymphotoxin Alpha (LTA) Polymorphism Is Associated with Prognosis of Non-Hodgkin's Lymphoma in a Chinese Population  

PubMed Central

Background Non-Hodgkin’s lymphoma (NHL) has been widely reported to be associated with autoimmune and pro-inflammatory response, and genetic polymorphisms of candidate genes involved in autoimmune and pro-inflammatory response may influence the survival and prognosis of NHL patients. To evaluate the role of such genetic variations in prognosis of NHL, we conducted this study in a Chinese population. Methods We used the TaqMan assay to genotype six single nucleotide polymorphisms (SNPs) (TNF rs1799964T>C, LTA rs1800683G>A, IL-10 rs1800872T>G, LEP rs2167270G>A, LEPR rs1327118C>G, TNFAIP8 rs1045241C>T) for 215 NHL cases. Kaplan-Meier analysis was performed to compare progression free survival among two common genotypes. Cox proportional hazard models were used to identify independent risk factors. Results We observed that LTA rs1800683G>A was significantly associated with risk of progression or relapse in NHL patients (HR?=?1.63, 95%CI?=?1.06–2.51; P?=?0.028), particularly in Diffuse large B cell lymphoma (DLBCL) cases (HR?=?1.50, 95%CI?=?1.10–2.04, P?=?0.01). Both univariate and multivariate Cox regression analysis showed that in DLBCL patients, Ann Arbor stage III/IV, elevated LDH level before treatment and LTA rs1800683 AA genotype carrier were independent risk factors for progression or relapse. While in NK/T cell lymphoma, Ann Arbor stage III/IV and elevated ?2-MG level before treatment indicated poorer prognosis. Conclusions The polymorphism of LTA rs1800683G>A contributes to NHL prognosis in a Chinese population. Further large-scale and well-designed studies are needed to confirm these results.

Variable Expression of B-cell Transcription Factors in Reactive Immunoblastic Proliferations: A Potential Mimic of Classical Hodgkin Lymphoma.  

PubMed

Reactive immunoblastic proliferations can histologically mimic classical Hodgkin lymphoma (CHL), and show diffuse CD30 expression in large cells. The lack of expression of CD15 in a subset of CHL further complicates their separation from immunoblastic proliferations. Loss of expression of B-cell transcription factors is frequently exploited in making a diagnosis of CHL; however, the staining patterns of B-cell transcription factors in immunoblastic proliferations have not been extensively studied. Thirty-three cases of reactive immunoblastic proliferations were evaluated using a panel of immunohistochemistry for CD30, CD15, CD20, CD3, ?, ?, CD45RB, MUM1, PAX5, OCT2, and BOB.1, as well as Epstein-Barr virus (EBV)/EBV-encoded ribonucleic acid in situ hybridization. A newly developed dual-color chromogenic in situ hybridization technology for detection of ?/? mRNAs was also used. The majority of immunoblasts expressed CD30 in 14 of 33 (42%) cases; none expressed CD15. Loss or weak expression of at least 1 transcription factor in B immunoblasts, most commonly PAX5, was noted in 24 of 29 (83%) cases. A polytypic light chain expression pattern was detected by immunohistochemistry in 14 of 22 (63.6%) cases and by dual-color chromogenic in situ hybridization in 9 of 10 (90%) cases studied. EBV-encoded ribonucleic acid was detected in 8 of 33 (24.2%) cases, 5 of which were clinically unrelated to infectious mononucleosis. We conclude that B-cell transcription factors can show loss or weak expression in a significant proportion of reactive immunoblastic proliferations, and, therefore, staining for B-cell transcription factors together with CD30 should be interpreted with caution before a diagnosis of CHL is made.

Chinese Tone and Vowel Processing Exhibits Distinctive Temporal Characteristics: An Electrophysiological Perspective from Classical Chinese Poem Processing  

PubMed Central

Classical Chinese poems have strict regulations on the acoustic pattern of each syllable and are semantically meaningless. Using such poems, this study characterized the temporal order of tone and vowel processing using event-related potentials (ERPs). The target syllable of the poem was either correct or deviated from the correct syllable at tone, vowel or both levels. Vowel violation elicited a negative effect between 300 and 500 ms regardless of the tone correctness, while tone violation elicited a positive effect between 600 and 1000 ms. The results suggest that the vowel information was available earlier than the tone information. Moreover, there was an interaction between the effect of vowel and tone violations between 600 and 1000 ms, showing that the vowel violation produced a positive effect only when the tone was correct. This indicates that vowel and tone processing interacts in the later processing stage, which involves both error detection and reanalysis of the spoken input. Implications of the present results for models of speech perception are discussed. PMID:24416438

Detection of ABCC1 expression in classical Hodgkin lymphoma is associated with increased risk of treatment failure using standard chemotherapy protocols  

PubMed Central

Background The mechanisms responsible for chemoresistance in patients with refractory classical Hodgkin lymphoma (CHL) are unknown. ATP-binding cassette (ABC) transporters confer multidrug resistance in various cancers and ABCC1 overexpression has been shown to contribute to drug resistance in the CHL cell line, KMH2. Findings We analyzed for expression of five ABC transporters ABCB1, ABCC1, ABCC2, ABCC3 and ABCG2 using immunohistochemistry in 103 pre-treatment tumor specimens obtained from patients with CHL. All patients received first-line standard chemotherapy with doxorubicin (Adriamycin®), bleomycin, vinblastine, and dacarbazine (ABVD) or equivalent regimens. ABCC1 was expressed in Hodgkin and Reed-Sternberg (HRS) cells in 16 of 82 cases (19.5%) and ABCG2 was expressed by HRS cells in 25 of 77 cases (32.5%). All tumors were negative for ABCB1, ABCC2 and ABCC3. ABCC1 expression was associated with refractory disease (p?=?0.01) and was marginally associated with poorer failure-free survival (p?=?0.06). Multivariate analysis after adjusting for hemoglobin and albumin levels and age showed that patients with CHL with HRS cells positive for ABCC1 had a higher risk of not responding to treatment (HR?=?2.84, 95%, CI: 1.12-7.19 p?=?0.028). Conclusions Expression of ABCC1 by HRS cells in CHL patients predicts a higher risk of treatment failure and is marginally associated with poorer failure-free survival using standard frontline chemotherapy regimens.

Pathobiology of Hodgkin Lymphoma  

PubMed Central

Hodgkin’s lymphoma is a lymphoid tumour that represents about 1% of all de novo neoplasms occurring every year worldwide. Its diagnosis is based on the identification of characteristic neoplastic cells within an inflammatory milieu. Molecular studies have shown that most, if not all cases, belong to the same clonal population, which is derived from peripheral B-cells. The relevance of Epstein-Barr virus infection at least in a proportion of patients was also demonstrated. The REAL/WHO classification recognizes a basic distinction between nodular lymphocyte predominance HL (NLPHL) and classic HL (CHL), reflecting the differences in clinical presentation, behavior, morphology, phenotype, molecular features as well as in the composition of their cellular background. CHL has been classified into four subtypes: lymphocyte rich, nodular sclerosing, mixed cellularity and lymphocyte depleted. Despite its well known histological and clinical features, Hodgkin’s lymphoma (HL) has recently been the object of intense research activity, leading to a better understanding of its phenotype, molecular characteristics and possible mechanisms of lymphomagenesis.

Classical Hodgkin's lymphoma in adults: guidelines of the Italian Society of Hematology, the Italian Society of Experimental Hematology, and the Italian Group for Bone Marrow Transplantation on initial work-up, management, and follow-up  

PubMed Central

The Italian Society of Hematology (SIE), the Italian Society of Experimental Haematology (SIES) and the Italian Group for Bone Marrow Transplantation (GITMO) commissioned a project to develop practice guidelines for the initial work-up, therapy and follow-up of classical Hodgkin’s lymphoma. Key questions to the clinical evaluation and treatment of this disease were formulated by an Advisory Committee, discussed and approved by an Expert Panel (EP) composed of senior hematologists and one radiotherapist. After a comprehensive and systematic literature review, the EP recommendations were graded according to their supporting evidence. An explicit approach to consensus methodologies was used for evidence interpretation and for producing recommendations in the absence of a strong evidence. The EP decided that the target domain of the guidelines should include only classical Hodgkin’s lymphoma, as defined by the WHO classification, and exclude lymphocyte predominant histology. Distinct recommendations were produced for initial work-up, first-line therapy of early and advanced stage disease, monitoring procedures and salvage therapy, including hemopoietic stem cell transplant. Separate recommendations were formulated for elderly patients. Pre-treatment volumetric CT scan of the neck, thorax, abdomen, and pelvis is mandatory, while FDG-PET is recommended. As to the therapy of early stage disease, a combined modality approach is still recommended with ABVD followed by involved-field radiotherapy; the number of courses of ABVD will depend on the patient risk category (favorable or unfavorable). Full-term chemotherapy with ABVD is recommended in advanced stage disease; adjuvant radiotherapy in patients without initial bulk who achieved a complete remission is not recommended. In the elderly, chemotherapy regimens more intensive than ABVD are not recommended. Early evaluation of response with FDG-PET scan is suggested. Relapsed or refractory patients should receive high-dose chemotherapy and autologous hemopoietic stem cells transplant. Allogeneic transplant is recommended in patients relapsing after autologous transplant. All fertile patients should be informed of the possible effects of therapy on gonadal function and fertility preservation measures should be taken before the initiation of therapy. PMID:19278966

Hodgkin lymphoma.  

PubMed

Hodgkin lymphoma (HL) is a curable malignancy which shows a bimodal curve in incidence in economically developed countries; there is a putative association with Epstein-Barr virus. The WHO 2008 classification schema recognises two histological types of HL: the nodular lymphocyte predominant and the "classic" HL. The latter encompasses four entities: nodular sclerosis, mixed cellularity, lymphocyte depletion, and lymphocyte-rich. Most patients with HL present with asymptomatic superficial lymphadenopathy. The commonest sites of disease are the cervical, supraclavicular and mediastinal lymph nodes, while sub-diaphragmatic presentations and bone marrow and hepatic involvement are less common. Splenic involvement is usually concomitant with hepatic disease and systemic symptoms; extranodal presentations are quite rare. Systemic symptoms are present in ?35% of cases. The stage of disease is defined according to the Ann Arbor staging system or its Cotswolds variant, and staging work-up includes physical examination, chest X-rays, chest and abdominal CT scan, and bone marrow biopsy. (18)FDG-PET ((18)fluordeoxyglucose positron emission tomography) plays a central role in staging, response assessment and prognosis definition. Classic HL usually spreads by contiguity within the lymphatic tissue network, with a late extension to adjacent and distant viscera. Mortality from HL has been progressively decreasing, as confirmed by the most recent 5-year survival figure of 81%. The list of putative prognostic factors in HL has been increasing, but most factors still require prospective validation. Some of these variables are used to stratify early-stage disease into "favourable" and "unfavourable" categories, with "unfavourable early-stage" being intermediate between "favourable early-stage" and "advanced-stage". ABVD (adriamycin(doxorubicin), bleomycin, vinblastine, dacarbazine) combination chemotherapy followed by involved-field irradiation is the standard treatment for patients with early-stage HL, with a 5-year OS >95%. Several trials assessing less intensive approaches for patients with favourable early-stage HL are ongoing. More intensified combinations, such as the BEACOPP (bleomycin, etoposide, adriamycin, cyclophosphamide, vincristine (Oncovin), procarbazine, prednisone) regimen, are being investigated, usually in patients with unfavourable early-stage HL and interim PET+. ABVD is the standard chemotherapy treatment also for patients with advanced disease. Although some evidence suggests that more intensive combinations provide better disease control, the inevitable increased risk of relevant late toxicity worries investigators. Consequently, there has been a shift towards investigating the innovative strategy of a more aggressive schedule for patients with (18)FDG-PET positive results after the first 2 courses of ABVD. High-dose chemotherapy supported by ASCT (autologous stem cell transplantation) is considered the standard of care in patients with HL which has relapsed after, or is refractory to conventional chemoradiotherapy, while allogeneic transplant is a suitable tool for patients with chemorefractory disease and patients failed after ASCT.

Hodgkin lymphoma  

PubMed Central

Hodgkin lymphoma (HL), a B cell–derived cancer, is one of the most common lymphomas. In HL, the tumor cells — Hodgkin and Reed-Sternberg (HRS) cells — are usually very rare in the tissue. Although HRS cells are derived from mature B cells, they have largely lost their B cell phenotype and show a very unusual co-expression of markers of various hematopoietic cell types. HRS cells show deregulated activation of multiple signaling pathways and transcription factors. The activation of these pathways and factors is partly mediated through interactions of HRS cells with various other types of cells in the microenvironment, but also through genetic lesions. The transforming events involved in the pathogenesis of HL are only partly understood, but mutations affecting the NF-?B and JAK/STAT pathways are frequent. The dependency of HRS cells on microenvironmental interactions and deregulated signaling pathways may offer novel strategies for targeted therapies. PMID:23023715

[Pathological diagnosis of Hodgkin lymphoma].  

PubMed

This lymphoma was recognized by Thomas Hodgkin in 1832. In 1865, Samuel Wilks named it Hodgkin disease. Now, the term Hodgkin lymphoma (HL) is acceptable over Hodgkin disease. Since the neoplastic cells of the disease is well-recognized to be a lymphoid cell, especially B lymphocyte. In WHO classification published in 2008, HLs are divided into two entities: Classical HL and nodular lymphocyte predominat HL. The former is composed of four different subtypes: nodular sclerosis (NS), mixed cellularity (MC), lymphocyte rich (LR), and lymphocyte depletion (LD). HL is characterized by the morphological feature comprising a minority of neoplastic cells, Hodgkin/Reed-Sternberg cells and popcorn (LP) cells and a majority of non-neoplastic reactive cells. Antigen receptor gene analyses by prevailing molecular methods and flow cytometry are not appropriate method for the diagnosis of HL, because of small number of neoplastic cells. They are, however, very useful in the differential diagnosis to rule out other lymphomas. Even the present when science progressed, pathological (morphological and immunohistochemical) examination is very worth for diagnosis of HL. PMID:24724402

Oral immunisation of swine with a classical swine fever vaccine (Chinese strain) and transmission studies in rabbits and sheep.  

PubMed

Seven experiments including a total of 47 pigs, 11 wild boars, 26 rabbits, 10 hares and 16 sheep were carried out to assess the efficacy, safety and transmission of the Chinese vaccine strain of the classical swine fever virus (CSFV) administrated by the oral route. Within 3 weeks after oral vaccination, a clear seroconversion occurred in the pigs. Six weeks after vaccination, vaccinated pigs were fully protected against a virulent challenge. The C-strain was not isolated from tonsils, spleen, lymph nodes, thymus, saliva, urine and faeces of pigs within 4 days after oral vaccination. In one experiment, susceptible pigs were placed in direct contact with vaccinated pigs. None of these contact-exposed pigs became serologically positive for CSFV antibodies. It is concluded that the C-strain induces protection in pigs when administrated by the oral route and is not shed by vaccinated pigs. Serum anti-CSFV antibodies developed in seven out of eight wild boars vaccinated by the oral route. No vaccine virus was detected in the spleen and tonsils of these animals. The results in wild boar were in accordance with those obtained in domestic pigs. Sheep did not show any clinical signs after oral vaccination while rabbits had moderate hyperthermia and growth retardation. No clinical response to oral immunisation in hares was detected. At the end of the experiment, no sheep had detectable serum antibodies against CSFV, whereas a few vaccinated rabbits and hares became seropositive. None of the contact-exposed rabbits and hares seroconverted. These data indicate that the C-strain is safe for sheep and as expected, moderately or not pathogenic for rabbits and hares. These efficacy and safety studies on oral vaccination with the C-strain under experimental conditions provide essential information for further studies in wild boars under experimental and field conditions, including assays with baits to control a CSF epidemic.

Nodular lymphocyte predominant hodgkin lymphoma: biology, diagnosis and treatment.  

PubMed

Nodular lymphocyte predominant Hodgkin lymphoma (NLPHL) is an uncommon variant of classical Hodgkin lymphoma. It is characterized histologically by presence of lymphohistiocytic cells which have B-cell phenotype, are positive for CD19, CD20, CD45, CD79a, BOB.1, Oct.2, and negative for CD15 and CD30. Patients often present with early stage of disease and do not have classical B symptoms. The clinical behavior appears to mimic that of an indolent non-Hodgkin lymphoma more than that of classical Hodgkin disease. The purpose of the present report is to define the biology of NLPHL, review its clinical presentation, and summarize the available clinical data regarding treatment. PMID:24650975

Hodgkin's lymphoma  

PubMed Central

Introduction People with Hodgkin's lymphoma usually present with a lump in the neck or upper chest, but a quarter of people also have fever, sweating, weight loss, fatigue, and itch. Almost all people with localised disease can be cured, and, even among people with relapsed advanced disease, almost 80% survive event free for 4 years or more. Methods and outcomes We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of: single-regimen chemotherapy treatments; combined chemotherapy and radiotherapy treatments compared with radiotherapy alone; and combined chemotherapy and radiotherapy treatments compared with the same chemotherapy agent alone, for first presentation stage I or II non-bulky disease? What are the effects of: specific combined chemotherapy and radiotherapy treatments versus each other; or different radiotherapy treatment strategies in stage I or II non-bulky disease? What are the effects of: single-regimen chemotherapy treatments; dose-intensified chemotherapy treatments; or combined chemotherapy plus radiotherapy treatments compared with chemotherapy alone, for first presentation stage II (bulky) disease, III, or IV disease? We searched: Medline, Embase, The Cochrane Library, and other important databases up to September 2008 (Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA). Results We found 40 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions. Conclusions In this systematic review, we present information relating to the effectiveness and safety of the following interventions: ABVD (with or without radiotherapy); ABVPP plus radiotherapy; ChlVPP-EVA; COPP-ABVD plus radiotherapy; CVPP plus radiotherapy; EBVP plus radiotherapy; escalating-dose BEACOPP; extended-field radiotherapy; increased-dose regimens; involved-field radiotherapy; MOPP (with or without radiotherapy); MOPP-ABV plus radiotherapy; and VBM plus radiotherapy.

Localized Nodular Lymphocyte Predominant Hodgkin Lymphoma is a rare disease with an overall good prognosis but frequent late relapses. Due to it's rarity there is no standard therapeutic approach and pathological diagnosis may be hard. In this paper we discuss the technical aspects of the radiation therapy and histological issues. The new fields reductions proposed for classical Hodgkin lymphoma cannot be applied to early stages Nodular Lymphocyte Predominant Hodgkin lymphomas which are usually treated with radiation therapy without systemic chemotherapy.

Modern management of lymphocyte-predominant Hodgkin lymphoma.  

PubMed

Nodular lymphocyte predominant Hodgkin lymphoma (NLPHL) represents 5% of all Hodgkin lymphoma and has distinct clinico-pathological features. It is typified by the presence of lymphocyte predominant cells, which are CD20(+) , CD15(-) and CD30(-) and are found scattered amongst small B-lymphocytes arranged in a nodular pattern. Patients typically are males presenting with localized, peripheral lymphadenopathy. Despite frequent and often late or multiple relapses the prognosis is favourable. Deaths due to NLPHL are uncommon, but secondary malignancies and other treatment toxicities contribute appreciably to overall mortality. Secondary aggressive non-Hodgkin lymphoma can occur in approximately 7-14% of cases of NLPHL. Given this diseases' rarity, the optimal management is unclear and opinions differ as to whether treatment paradigms should be similar to or differ from those for classical Hodgkin lymphoma. This review provides an overview of the existing literature describing of the outcome and treatment approaches for limited and advanced stage NLPHL. PMID:23398605

Chinese Herbalism  

PubMed Central

Chinese herbalism dates back to 2852 B.C. More than 2,600 herbs and thousands of herbal formulae are used to treat illness. Classical theories of Chinese medicine are integrated with the Taoist philosophy, whereby the universe is composed of two basic forces: a positive one called yang, and a negative one called yin. Illness is thought to occur when there is too much yang (tonification) or too much yin (sedation) in the body and herbal medicines are therefore intended either to tonify or to sedate the body so that balance is restored. Since 1954, some Chinese herbal remedies have been scientifically analyzed and tested. Several have been proven effective in treating a variety of diseases and conditions. PMID:21283498

SUMMARY Frances Hodgkins was one of a number of expatriate New Zealanders during the early twentieth century who lived in Britain or Europe, where it was easier to find supportive friendship circles for their lives as artists or as people attracted to their own sex. In this article, I explore the primacy of women in Hodgkins' life and read this as lesbian and argue that many of these relationships were sexual, from the evidence of her letters, which suggest that she moved in lesbian worlds of work and friendship. I also discuss the financial and emotional support given by her male homosexual as well as her lesbian friends who made her life as an artist possible. PMID:24807565

Hodgkin's lymphoma: the pathologist's viewpoint  

PubMed Central

Despite its well known histological and clinical features, Hodgkin's lymphoma (HL) has recently been the object of intense research activity, leading to a better understanding of its phenotype, molecular characteristics, histogenesis, and possible mechanisms of lymphomagenesis. There is complete consensus on the B cell derivation of the tumour in most cases, and on the relevance of Epstein-Barr virus infection and defective cytokinesis in at least a proportion of patients. The REAL/WHO classification recognises a basic distinction between lymphocyte predominance HL (LP-HL) and classic HL (CHL), reflecting the differences in clinical presentation and behaviour, morphology, phenotype, and molecular features. CHL has been classified into four subtypes: lymphocyte rich, nodular sclerosing, with mixed cellularity, and lymphocyte depleted. The borders between CHL and anaplastic large cell lymphoma have become sharper, whereas those between LP-HL and T cell rich B cell lymphoma remain ill defined. Treatments adjusted to the pathobiological characteristics of the tumour in at risk patients have been proposed and are on the way to being applied. PMID:11896065

Cytopathology: LC06-1 HODGKIN LYMPHOMA: DIAGNOSTIC CRITERIA AND PITFALLS.  

PubMed

The histopathological and fine-needle aspiration (FNA) cytologic diagnosis of Hodgkin lymphoma (HL) is based on demonstration of pathognomonic mononucleated Hodgkin and bi- to multinucleated Reed-Sternberg (HRS) cells among reactive cellular components composed of lymphocytes, benign histiocytes, neutrophils and eosinophils. In the WHO classification, Hodgkins lymphoma is classified as nodular lymphocytic predominant HL (NLPHL) and classical HL which is in turn sub-classified into lymphocyte-rich (LR), mixed cellular (MC), lymphocytic depleted (MC) and nodular sclerosis (NS) types. The sub-classification of classical HL into LR, MC, and LD depends on relative proportions of neoplastic HRS cells and reactive cellular components. Whereas in HL-NS shows a special type of R-S cells called lacunar cells, NLPHL is characterized by popcorn cells. CHL-MC to some extent and other HL subtypes to a large extent may pose diagnostic challenges in the cytologic material. Reed-Sternberg-like cells have been reported in benign lympho-proliferative conditions like reactive hyperplasia and infectious mononucleosis, and certain of non-Hodgkin lymphoma subtypes as well as non-lymphoid malignancies like metastatic carcinoma, melanoma, sarcomas and germ cell tumors. Non-Hodgkin lymphoma subtypes, e.g., anaplastic large cell lymphoma, T-cell-histiocytic-rich B-cell lymphoma, and pleomorphic peripheral T-cell lymphoma, which can be misdiagnosed as Hodgkin lymphoma, need immunohistochemical studies to be differentiated.

Hodgkin's lymphoma with exuberant granulomatous reaction.  

PubMed

We report a 36-year-old woman, presented with cervical lymphadenopathy and low-grade fever. Two fine needle aspiration cytology and one excisional biopsy were performed in the referral hospital, all showed granulomatous lesions without necrosis. A tentative diagnosis of tuberculosis was made, and she started on antituberculous treatment. However, there was no clinical improvement. She presented to our institution one year after the initial diagnosis, and a new biopsy from the cervical lymph node revealed effacement of the whole node by marked non-necrotizing granulomatous reaction. However, there were scattered large cells with few classic Reed-Sternberg cells between the granulomas. Immunohistochemistry reveals strong reaction of CD15 and CD30, and negative staining for CD45RB, CD45RO, and CD20. These findings confirmed the diagnosis of Hodgkin's lymphoma with remarkable granulomatous reaction that almost masked the malignant component. She was treated with chemotherapy, and she showed an excellent response. PMID:17143374

Fumanjian, a Classic Chinese Herbal Formula, Can Ameliorate the Impairment of Spatial Learning and Memory through Apoptotic Signaling Pathway in the Hippocampus of Rats with A?1–40-Induced Alzheimer's Disease  

PubMed Central

Alzheimer's disease (AD) is the most common form of dementia and lacks disease-altering treatments. Fumanjian (FMJ), a famous classic Chinese herbal prescription for dementia, was first recorded in the Complete Works of Jingyue during the Ming Dynasty. This study aimed to investigate whether FMJ could prevent cognitive deficit and take neuroprotective effects in A?1–40-induced rat model through apoptotic signaling pathway. AD model was established by bilateral injection of A?1–40 into hippocampus in rat. All rats were tested for their capabilities of spatial navigation and memorization by Morris water maze. Apoptosis was tested using TUNEL staining in hippocampus neuronal cells; RT-PCR tested expression of Bcl-2 and Bax mRNA; western blotting tested protein level of cleaved caspase-3. After 14 days of treatment, FMJ significantly improved the escape latency and enhanced platform-cross number compared with the A?1–40-injected group (P < 0.05 or P < 0.01). FMJ also significantly decreased number of TUNEL-positive neuronal apoptosis and the expressions of Bax and cleaved Caspase-3 and increased the expression of Bcl-2 (P < 0.01) compared with AD model group. In conclusion, FMJ exerts a protective effect against A?1–40-induced learning and memory deficits and neuronal apoptosis, suggesting that FMJ could be used as a potential therapeutic formula for AD.

Lymphocyte-predominant Hodgkin's disease. An immunohistochemical analysis of 208 reviewed Hodgkin's disease cases from the German Hodgkin Study Group.  

PubMed Central

There is wide consensus that lymphocyte predominance Hodgkin's disease (LPHD) represents a distinct clinicopathological entity of B-cell origin. However, inconsistent results of immunophenotyping studies and low confirmation rates among multi-center trials pose the question of whether LPHD really expresses heterogeneous marker profiles or whether it represents a mixture of morphologically similar entities. Among 2,836 cases reviewed by the German Hodgkin Study Group, immunophenotyping was performed on 1) cases classified or confirmed as LPHD by the reference panel (n = 104) or 2) cases not confirmed as LPHD but classified as classical HD (cHD) within the reference study trial (n = 104). In most cases, immunohistochemistry revealed a phenotype either LPHD-like (CD20+, CD15-, CD30-, CD45+) or cHD-like (CD15+, CD30+, CD20-, CD45-). In 27 cases, the immunophenotype was not fully conclusive. Additional markers for Epstein-Barr virus and CD57 and in situ hybridization for mRNA light chains allowed for a more clear-cut distinction between LPHD and cHD. However, in 25 of 104 cases, immunohistochemistry disproved the morphological diagnosis of LPHD of the panel experts, whereas 13 cases originally not confirmed as LPHD showed a LPHD-like immunopattern. Immunohistochemically confirmed LPHD cases showed a significantly better freedom from treatment failure (P = 0.033) than cHD; this was not observed in the original study classification based only on morphology (P > 0.05). Significantly better survival for LPHD cases improved from P = 0.047 (original study classification) to P = 0.0071 when classified by immunohistochemistry. Our results show that LPHD is a more immunohistochemical rather than a purely morphological diagnosis. Immunophenotyping of HD biopsies suspected of being LPHD is mandatory when a modified therapy protocol, that is, one different from those used in cHD, is discussed.

EXPONENTIAL TIME DIFFERENCING FOR HODGKIN-HUXLEY-LIKE ODES  

PubMed Central

Several authors have proposed the use of exponential time differencing (ETD) for Hodgkin–Huxley-like partial and ordinary differential equations (PDEs and ODEs). For Hodgkin–Huxley-like PDEs, ETD is attractive because it can deal effectively with the stiffness issues that diffusion gives rise to. However, large neuronal networks are often simulated assuming “space-clamped” neurons, i.e., using the Hodgkin–Huxley ODEs, in which there are no diffusion terms. Our goal is to clarify whether ETD is a good idea even in that case. We present a numerical comparison of first- and second-order ETD with standard explicit time-stepping schemes (Euler’s method, the midpoint method, and the classical fourth-order Runge–Kutta method). We find that in the standard schemes, the stable computation of the very rapid rising phase of the action potential often forces time steps of a small fraction of a millisecond. This can result in an expensive calculation yielding greater overall accuracy than needed. Although it is tempting at first to try to address this issue with adaptive or fully implicit time-stepping, we argue that neither is effective here. The main advantage of ETD for Hodgkin–Huxley-like systems of ODEs is that it allows underresolution of the rising phase of the action potential without causing instability, using time steps on the order of one millisecond. When high quantitative accuracy is not necessary and perhaps, because of modeling inaccuracies, not even useful, ETD allows much faster simulations than standard explicit time-stepping schemes. The second-order ETD scheme is found to be substantially more accurate than the first-order one even for large values of ?t. PMID:24058276

Simultaneous presentation of relapsing Hodgkin's disease and treatment-related non-Hodgkin's lymphoma  

SciTech Connect

A 55-year-old white man was diagnosed in 1975 with Hodgkin's disease stage IIA, mixed cellularity. He was treated with 4,500 rads to an inverted-Y field followed by six cycles of MOPP and remained in complete remission. In 1983 a right axillary lymph node biopsy showed recurrent Hodgkin's disease, mixed cellularity. While receiving his initial chemotherapy he developed persistent epigastric distress. Endoscopic gastric biopsy demonstrated a diffuse large-cell non-Hodgkin's lymphoma. Surface marker studies confirmed the separate identity of these two malignant lymphoproliferative processes. This represents the first reported simultaneous occurrence of relapsing Hodgkin's disease with treatment-related non-Hodgkin's lymphoma.

Hodgkin's Lymphoma: A Review of Neurologic Complications.  

PubMed

Hodgkin's lymphoma is a hematolymphoid neoplasm, primarily of B cell lineage, that has unique histologic, immunophenotypic, and clinical features. Neurologic complications of Hodgkin's Lymphoma can be separated into those that result directly from the disease, indirectly from the disease, or from its treatment. Direct neurologic dysfunction from Hodgkin's Lymphoma results from metastatic intracranial spinal disease, epidural metastases causing spinal cord/cauda equina compression, leptomeningeal metastases, or intradural intramedullary spinal cord metastases. Indirect neurologic dysfunction may be caused by paraneoplastic disorders (such as paraneoplastic cerebellar degeneration or limbic encephalitis) and primary angiitis of the central nervous system. Hodgkin's lymphoma treatment typically includes chemotherapy or radiotherapy with potential treatment-related complications affecting the nervous system. Neurologic complications resulting from mantle-field radiotherapy include the "dropped head syndrome," acute brachial plexopathy, and transient ischemic attacks/cerebral infarcts. Chemotherapy for Hodgkin's lymphoma may cause cerebral infarction (due to emboli from anthracycline-induced cardiomyopathy) and peripheral neuropathy. PMID:20975772

Therefore, the interface for entering data has been divided into several parts. Each part is subjected to separate editing and transfer. A double-layer debugging system has been applied in the program: the first pass occurs on the client side (programmed in JavaScript and XML), the second - on the server side (programmed in PHP). Strict authorization is requested for all participants. Clinical data collected according to management standards and information governance (data quality, security and confidentiality) is organized in a way that facilitates practical and scientific use.

We report the case of a patient who presented with new onset hypotension and was diagnosed with urosepsis and septic shock requiring pressor support for maintaining his blood pressure. computed tomography (CT) scan of abdomen showed liver lesions, which were new on comparison with a CT abdomen done 3 weeks back. Biopsy of the liver lesions and subsequently a bone marrow biopsy showed large atypical Reed-Sternberg cells, positive for CD15 and CD 30 and negative for CD45, CD3 and CD20 on immuno-histochemical staining, hence establishing the diagnosis of Hodgkin lymphoma. The mechanism involved in Hodgkin lymphoma causing hypotension remains anecdotal, but since it is mostly seen in patients with advanced Hodgkin lymphoma, it is hypothetically related to a complex interaction between cytokines and mediators of vasodilatation. Here we review relevant literature pertaining to presentation and pathogenesis of this elusive and rare association. PMID:25317321

Systemic to pulmonary fistulas in Hodgkin's disease.  

PubMed

Systemic to pulmonary fistula is an unusual entity and its association with hematological diseases like Hodgkin's is extremely rare. We present a case of a 26-year-old woman with a thoracic mass and large arteriovenous fistula. The diagnosis of Hodgkin's disease, nodular sclerosis, was obtained by a biopsy of the supraclavicular lymph node. We achieved an excellent response after combined treatment with chemotherapy, radiotherapy and arterial embolization with complete disappearance of the mass. PMID:10940804

CD40 expression in Hodgkin's disease.  

PubMed Central

CD40 is a transmembrane protein that belongs to a superfamily of proteins related to nerve growth factor receptor. CD40 is expressed on B cells and some B cell malignancies. It appears to be involved in B cell proliferation and the prevention of apoptosis in germinal center cells, which is accompanied by expression of bcl-2. Its expression is up-regulated by the EBV protein latent membrane protein-1 and cytokines interleukin-4 and interferon-gamma. The expression of CD40 in 37 cases of Hodgkin's disease and 23 cases of non-Hodgkin's lymphoma (11 T cell lymphomas and 12 B cell lymphomas) was examined by paraffin section immunohistochemistry using the BB-20 monoclonal antibody. In 26 of 37 cases of Hodgkin's disease the Reed-Sternberg cells showed strong membrane or cytoplasmic expression of CD40. Only 3 of 23 non-Hodgkin's lymphomas showed any expression of CD40 and then only weakly. There was no correlation between expression of bcl-2 or latent membrane protein-1 with CD40 expression. These results show that there is probable hyperexpression of CD40 in Hodgkin's disease and suggest that dysregulation of CD40 expression may play a role in the pathogenesis of Hodgkin's disease.

Relapsed Hodgkin lymphoma: management strategies.  

PubMed

Although Hodgkin lymphoma (HL) is largely curable with first-line therapy, approximately one-third of patients will not have a complete response to frontline treatment or will subsequently relapse. Only 50% of these patients will be effectively salvaged with conventional therapies. The prognosis is particularly poor for those patients with chemotherapy refractory disease, who are unable to obtain even transient disease control, and for patients who relapse following high dose chemotherapy and autologous stem cell transplant. In this review, we summarize the most recent updates on the management of patients with relapsed HL, the role of novel therapies such as brentuximab vedotin, and an overview of promising new agents currently under investigation. We also discuss the role of consolidation strategies such as high-dose chemotherapy and autologous stem cell transplant, and reduced-intensity allogeneic hematopoietic stem cell transplant, and the need for new strategies in the elderly patient population.

Radiation-induced splenic atrophy in patients with Hodgkin's disease and non-Hodgkin's lymphomas  

SciTech Connect

Effective treatment of Hodgkin's disease requires the determination of the extent of the disease. This usually involves staging laparotomy, which includes splenectomy and biopsies of the para-aortic lymph nodes, liver, and bone marrow. Absence of the spleen predisposes a person to fulminant septicemia from encapsulated bacteria, a risk even greater in patients undergoing treatment for Hodgkin's disease. For this reason, some investigators have suggested that spleens not be removed for diagnosis but, rather, that they be included within the fields of radiation, which would preserve normal splenic function. We present a case of fatal spontaneous pneumococcal sepsis in a patient with splenic atrophy; the sepsis occurred 12 years after successful treatment of Hodgkin's disease by total nodal and splenic irradiation. A retrospective study of patients treated for Hodgkin's and non-Hodgkin's lymphomas indicated that atrophy and functional asplenia may be an important sequela of splenic irradiation.

Genomic Instability: The Driving Force behind Refractory/Relapsing Hodgkin's Lymphoma  

PubMed Central

In classical Hodgkin’s lymphoma (HL) the malignant mononuclear Hodgkin (H) and multinuclear, diagnostic Reed-Sternberg (RS) cells are rare and generally make up <3% of the total cellular mass of the affected lymph nodes. During recent years, the introduction of laser micro-dissection techniques at the single cell level has substantially improved our understanding of the molecular pathogenesis of HL. Gene expression profiling, comparative genomic hybridization analysis, micro-RNA expression profiling and viral oncogene sequencing have deepened our knowledge of numerous facets of H- and RS-cell gene expression deregulation. The question remains whether disturbed signaling pathways and deregulated transcription factors are at the origin of refractory/relapsing Hodgkin’s lymphoma or whether these hallmarks are at least partially related to another major factor. We recently showed that the 3D nuclear organization of telomeres and chromosomes marked the transition from H- to RS-cells in HL cell lines. This transition is associated with progression of telomere dysfunction, shelterin disruption and progression of complex chromosomal rearrangements. We reported analogous findings in refractory/relapsing HL and identified the shelterin proteins TRF1, TRF2 and POT1 as targets of the LMP1 oncogene in post-germinal center B-cells. Here we summarize our findings, including data not previously published, and propose a model in which progressive disruption of nuclear integrity, a form of genomic instability, is the key-player in refractory/relapsing HL. Therapeutic approaches should take these findings into account. PMID:24216998

Non-Hodgkin's lymphoma among Vietnam veterans.  

PubMed

In light of findings suggesting an increase in the risk for non-Hodgkin's lymphoma among men exposed to phenoxyherbicides and concerns among veterans over Agent Orange exposure, a hospital-based case-control study was undertaken to examine the association between military service in Vietnam and non-Hodgkin's lymphoma. The cases consisted of 201 Vietnam-era veteran patients who were treated in one of 172 Department of Veterans Affairs hospitals from 1969 through 1985 with a diagnosis of non-Hodgkin's lymphoma. 358 Vietnam-era veteran patients with a diagnosis other than malignant lymphoma served as a comparison group. Military service information was obtained from a review of the veteran's military personnel records. Service in Vietnam did not increase the risk of non-Hodgkin's lymphoma either in general (branch adjusted odds ratio = 1.03, 95% confidence interval = 0.70-1.50) or with increased latency period as defined as the duration in years from first service in Vietnam to hospital discharge. Surrogate measures of potential Agent Orange exposure such as service in a specific military branch, in a certain region within Vietnam, or in a combat role as determined by military occupational speciality were not associated with any increased risk of non-Hodgkin's lymphoma.

Prognostic Factors in Hodgkin Lymphoma  

PubMed Central

Hodgkin lymphoma (HL) is among the neoplastic diseases that has the best long-term outcome after cytotoxic treatment. Cure rates approach 80–90%; however, 15–20% of patients will be resistant to therapy (primary refractory) or relapse after treatment. Prognostic factors should help to stratify treatment according to the risk profile and identify patients at risk for failure. Significance of prognostic factors partly depends on the efficacy of the treatments administered, since new effective therapies can variably counterbalance the adverse effects of some unfavorable clinical determinants. As a consequence, some prognostic factors thought to be important in the past may become meaningless when modern successful therapies are used. Therefore, the value of prognostic factors has to be updated periodically, and then adapted to new emerging biomarkers. Besides the prognostic role of PET imaging, tissue and circulating biomarkers, as the number of tumor-infiltrating macrophages, cytokine and chemokine levels and profiling of circulating nucleic acids (DNA and microRNAs) have shown promise.

Hodgkin's disease and Vietnam service.

Earlier studies that showed an association between exposure to phenoxy herbicides and the risk of malignant lymphomas have sparked concerns among Vietnam veterans over Agent Orange exposure. The Department of Veterans Affairs (VA) undertook a hospital-based case-control study to examine the association between military service in Vietnam and several histologic types of malignant lymphomas. This is a report of 283 Vietnam-era veteran patients who were treated in one of 172 VA hospitals from 1969 to 1985 with a diagnosis of Hodgkin's Disease (HD). Four hundred and four Vietnam-era veteran patients with diagnosis other than malignant lymphoma served as a comparison group. Military service in Vietnam was not associated with any significant increase in the risk of HD (adjusted odds ratio = 1.28; 95% confidence interval = 0.94, 1.76). Surrogate measures of potential Agent Orange exposure such as service in a specific military branch, in a certain region within Vietnam, in a combat role, or extended Vietnam service time were not associated with any significant increased risk of HD.

Aquired toxoplasmosis (AT) is one kind of lymphoadenopathy without fever and fatigue. When the two diseases coexist, clinical and pathological misdiagnosis may be made. This is the first male case of toxoplasmosis and Hodgkin's disease in China, diagnosed by surgical removal of the major part of the cervical and supraclavicular masses, detection of blood anti-toxoplasma gondii antibody, PCR analysis of toxoplasma gondii DNA, and pathological, ultrastructural and immunohistochemical studies of the tumour tissues.

Hydrocele following treatment for Hodgkin's disease  

SciTech Connect

Thirteen Hodgkin's disease patients developed hydrocele after treatment with radiotherapy (12 patients) or chemotherapy (one patient). An additional patient developed testicular swelling following radiotherapy and chemotherapy. Eleven of 13 patients were staged with laparotomy (nine initially, two at restaging) which included pelvic and aortic node biopsies prior to development of hydrocele. Five of the patients developed radiation-related pericarditis. These data suggest that staging and treatment of Hodgkin's disease may disrupt pelvic lymphatic flow and lead to hydrocele formation. The high incidence of treatment-related pericarditis may suggest unusual sensitivity to radiation in this group of patients.

Hodgkin’s lymphoma presenting as a complex paraneoplastic neurological syndrome: a case report  

PubMed Central

Introduction Paraneoplastic neuropathies are rare. They are often difficult to diagnose, especially when they precede the diagnosis of cancer. Hodgkin's lymphoma is associated with multiple paraneoplastic neurological syndromes, of which demyelinating polyneuropathies are very unusual. Association with chronic inflammatory demyelinating polyneuropathy is even more uncommon. Case presentation We report the rare case of a 74-year-old Caucasian man who presented with a complex neurological syndrome and was eventually diagnosed with the nodular sclerosing variant of Hodgkin's lymphoma. With timely diagnosis and early institution of treatment of the underlying malignancy, our patient began to show gradual improvement of his symptoms. Conclusion Hodgkin's lymphoma is associated with several paraneoplastic neurological syndromes. Sometimes it can be the only presenting feature of an underlying Hodgkin's lymphoma, posing a diagnostic challenge. Prompt oncologic treatment and immunotherapy can be beneficial if instituted early in the course of the disease. PMID:23566362

Thyroid dysfunction in Hodgkin's disease.  

PubMed

Radiotherapy to the neck and/or polychemotherapy late effects on the thyroid were investigated in 51 patients (34 males and 17 females) with Hodgkin's disease. Except for two untreated, recently diagnosed patients, all were studied after 1 to 105 months (median, 27.5 months) of completion of polychemotherapy. Age ranged from 6.2 to 36.6 years (median, 13.6 years). Patients were divided according to treatment into four groups: (A) patients treated with CVPP (cyclophosphamide, vinblastine, procarbazine, and prednisone); (B) 22 patients treated with CVPP plus radiotherapy (median radiation dose to the thyroid, 3000 cGy); (C) seven patients with ACOP/BVP (adriamycin, cyclophosphamide, vincristine, prednisone, bleomycin, vinblastine, procarbazine); and (D) seven patients treated with different polychemotherapy protocols, four of whom also received radiotherapy. Elevated basal and/or post-TRH, -TSH levels were found in the following: Group A: two of 12 patients (17%); Group B: 11 of 22 (50%); Group C: four of seven (57%); and Group D: two of seven (28%). Positive antimicrosomal thyroid antibody titers (AM Ab) were found in the following: Group A: three of 12 patients (25%); Group B: six of 21 (28%), Group C: two of seven (28%); and Group D: one of six (17%). Of 46 patients studied, 12 (26%) had positive AM Ab; 37 of 46 patients were younger than 20 years of age, 11 (30%) of whom had positive AM Ab versus 4% in the normal population (P less than 0.001). Two recently diagnosed, untreated patients had either high TSH response to TRH or positive AM Ab. In conclusion, higher frequency of thyroid dysfunction was observed in patients receiving radiotherapy (50% versus 27%). Prevalence of positive AM Ab, apparently unrelated to therapy, was higher in young patients than in the normal population. A predisposition to autoimmune thyroid disease seems to be present in these patients, but it is not possible to discern how lymphoma and thyroiditis are interrelated. PMID:2463071

Incomplete cytokinesis and re-fusion of small mononucleated Hodgkin cells lead to giant multinucleated Reed-Sternberg cells.  

PubMed

Multinucleated Reed-Sternberg (RS) cells are pathognomonic for classical Hodgkin lymphoma (HL), and their presence is essential for diagnosis. How these giant tumor cells develop is controversial, however. It has been postulated that RS cells arise from mononucleated Hodgkin cells via endomitosis. Conversely, continuous single-cell tracking of HL cell lines by long-term time-lapse microscopy has identified cell fusion as the main route of RS cell formation. In contrast to growth-induced formation of giant Hodgkin cells, fusion of small mononuclear cells followed by a size increase gives rise to giant RS cells. Of note, fusion of cells originating from the same ancestor, termed re-fusion, is seen nearly exclusively. In the majority of cases, re-fusion of daughter cells is preceded by incomplete cytokinesis, as demonstrated by microtubule bonds among the cells. We confirm at the level of individual tracked cells that giant Hodgkin and RS cells have little proliferative capacity, further supporting small mononuclear Hodgkin cells as the proliferative compartment of the HL tumor clone. In addition, sister cells show a shared propensity for re-fusion, providing evidence of early RS cell fate commitment. Thus, RS cell generation is related neither to cell fusion of unrelated Hodgkin cells nor to endomitosis, but rather is mediated by re-fusion of daughter cells that underwent mitosis. This surprising finding supports the existence of a unique mechanism for the generation of multinuclear RS cells that may have implications beyond HL, given that RS-like cells are frequently observed in several other lymphoproliferative diseases as well.

Aneuploidy in sperm of Hodgkin`s disease patients receiving NOVP chemotherapy  

SciTech Connect

Induction of genetic damage in germ cells of young patients receiving chemo- or radiotherapy for cancers with probable cure, such as Hodgkin`s disease, is cause for concern. These young patients may someday desire children, and germ cell alterations presenting as numerical chromosomal abnormalities in sperm may place their future offspring at risk. To address this concern, we measured aneuploidy in sperm from eight young Hodgkin`s disease patients: four pre-treatment, four during treatment, and three over a 45 month period following treatment with NOVP (Novantrone, Oncovin, Vinblastine and Prednisone). Patients ranged in stage of disease from IA-IIEB and none had received prior radiation or chemotherapy. Using multi-chromosome sperm FISH with repetitive sequence probes specific for chromosomes X, Y and 8, we found a significant 2-4 fold increase in particular numerical chromosomal abnormalities during treatment which were limited in persistence post-treatment. Additionally, pre-treatment Hodgkin`s disease patients showed elevations in some numerical chromosomal abnormalities when compared to a healthy reference group. In several men, the fraction of aneuploid sperm did not return to healthy reference group levels even after completion of therapy. These results show that elevated sperm aneuploidy occurs in germ cells of young cancer patients during chemotherapy and suggest caution to prevent conceptions during this period. The elevated sperm aneuploidy appears transient, but in some cases never returns to healthy reference group levels.

ACR Appropriateness Criteria Pediatric Hodgkin Lymphoma.  

PubMed

Pediatric Hodgkin lymphoma is a highly curable malignancy and potential long-term effects of therapy need to be considered in optimizing clinical care. An expert panel was convened to reach consensus on the most appropriate approach to evaluation and treatment of pediatric Hodgkin lymphoma. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed every 2 years by a multidisciplinary expert panel. The guideline development and review include an extensive analysis of current medical literature from peer reviewed journals and the application of a well-established consensus methodology (modified Delphi) to rate the appropriateness of imaging and treatment procedures by the panel. In those instances where evidence is lacking or not definitive, expert opinion may be used to recommend imaging or treatment. Four clinical variants were developed to assess common clinical scenarios and render recommendations for evaluation and treatment approaches to pediatric Hodgkin lymphoma. We provide a summary of the literature as well as numerical ratings with commentary. By combining available data in published literature and expert medical opinion, we present a consensus to the approach for management of pediatric Hodgkin lymphoma. PMID:24616347

Alopecia areata as a paraneoplastic syndrome of Hodgkin's lymphoma: A case report  

PubMed Central

Alopecia areata (AA) has been classically associated with several autoimmune disorders. However, AA as a paraneoplastic syndrome of Hodgkin’s lymphoma (HL) remains a rare entity and our understanding of this phenomenon is limited to a few case reports. This is the case report of a 46-year-old male patient who was diagnosed with AA several months prior to the onset of B symptoms and the diagnosis of stage IVB classical HL. The patient was subsequently treated with 6 cycles of adriamycin, bleomycin, vinblastine and dacarbazine and experienced a complete response and resolution of his AA. In our case, the onset of AA preceded the onset of systemic manifestations and diagnosis of HL, whereas in other cases AA was shown to occur concurrently with the clinical manifestations of HL. In all the cases, however, treatment of the HL subsequently led to resolution of the AA. The present case report highlights the significance of AA as a herald of underlying malignancy, although AA in classical HL remains poorly characterized in the literature. PMID:24940502

Role of brentuximab vedotin in the treatment of relapsed or refractory Hodgkin lymphoma  

PubMed Central

Brentuximab vedotin (BV) is an antibody-drug conjugate that targets CD30-positive malignancies via an anti-CD30 monoclonal antibody linked to monomethyl auristatin E, a microtubule-disrupting agent, by a protease-cleavable linker. BV has received accelerated approval from the US Food and Drug Administration for the treatment of classical Hodgkin lymphoma that has relapsed either after autologous stem cell transplantation (ASCT) or after two lines of combination chemotherapy in patients ineligible for ASCT, and in systemic anaplastic large cell lymphoma after failure of at least one line of multiagent chemotherapy. Phase I studies in CD30-positive lymphomas have determined the maximum tolerated dose to be 1.8 mg/kg intravenously every 21 days. In relapsed/refractory Hodgkin lymphoma, a pivotal Phase II study of single-agent BV showed an overall response rate of 75%, with 34% complete responses and a median remission duration of 20 months for complete responders. BV has a modest toxicity profile, with peripheral neuropathy as one of the most clinically significant side effects, and this is largely reversible. Therefore, BV is the treatment of choice for patients with relapsed/refractory Hodgkin lymphoma after ASCT or two standard regimens. Ongoing trials are evaluating the role of BV as salvage therapy prior to ASCT and for maintenance after ASCT for patients with relapsed/refractory disease. PMID:24672256

An analysis of CB1 expression and function in Hodgkin lymphoma (HL), one of the most frequent lymphomas, was not performed to date. Design and Methods We examined the distribution of CB1 protein in primary cases of HL. Using lymphoma derived cell lines, the role of CB1 signaling on cell survival was investigated. Results A predominant expression of CB1 was found in Hodgkin-Reed-Sternberg cells in a vast majority of classical HL cases. The HL cell lines L428, L540 and KM-H2 showed strong CB1-abundance and displayed a dose-dependent decline of viability under CB1 inhibition with AM251. Further, application of AM251 led to decrease of constitutively active NF?B/p65, a crucial survival factor of HRS-cells, and was followed by elevation of apoptotic markers in HL cells. Conclusions The present study identifies CB1 as a feature of HL, which might serve as a potential selective target in the treatment of Hodgkin lymphoma. PMID:24349109

Hodgkin's lymphoma rectosigmoid in a patient with ulcerative colitis on long-term azathioprine therapy.  

PubMed

Hodgkin's lymphoma complicating chronic ulcerative colitis is extremely rare. We report a case of extranodal Hodgkin's lymphoma involving rectosigmoid in a patient of chronic ulcerative colitis on long-term azathioprine. A 67-year-old man presented with extensive ulcerative colitis, on follow-up since September 2005. He received long-term steroids, mesalamine and azathioprine. Serial surveillance colonoscopic examinations and colonic biopsies were performed. Surveillance colonoscopy performed 8?years after the onset of disease showed multiple deep ulcers and nodular masses involving the rectum and sigmoid colon. Histological examination of rectosigmoid biopsies showed classic Hodgkin's disease. Azathioprine was withdrawn. He received mechlorethamine, vincristine, procarbazine and prednisone (MOPP) chemotherapy protocol and was planned for total colectomy in follow-up. We believe patients with ulcerative colitis on long-term azathioprine should be on vigil for development of lymphomas by protocol surveillance colonoscopic examinations and biopsies. The risk of lymphoma in such patients is small and outweighs the benefits of long-term azathioprine therapy. PMID:24849639

Chinese Dinosaurs  

NSDL National Science Digital Library

What's "Jurassic Park" in Mandarin? That isn't easy to say, but if you're interested in Chinese dinosaurs, then you will love the new online (and real) exhibit hosted by the Australian Museum in Sydney. A vast land containing many of the world's best-preserved dinosaur specimens, China offers remnants of many species not commonly available in Western exhibits. With lots to explore, the site features a readily accessible list of dinosaurs, each arranged under its Chinese-derived species name. Not like anything most of us have ever heard, many of the specimens look and seem familiar, at least as members of the dinosaur family. While generally well-executed, particularly worthy of note is the site's presentation of China's celebrated feathered dinosaurs, Caudipteryx zoui and Protarchaeopteryx, two curious figures believed to represent part of the great reptilian leap from land to air.

Late-onset cervicoscapular muscle atrophy and weakness after radiotherapy for Hodgkin disease: a case series.  

PubMed

Patients with cervical or mediastinal Hodgkin disease (HD) classically underwent chemotherapy plus extended-field radiation therapy. We report six patients who gradually developed severe atrophy and weakness of cervical paraspinal and shoulder girdle muscles 5-30 years after mantle irradiation for HD. Although clinical presentation was uniform, including a dropped head syndrome, electrophysiological and pathological findings were rather heterogeneous. Either neurogenic or myogenic processes may be involved and sometimes combined. We discuss the pathophysiological mechanisms underlying these cervicoscapular motor complications of mantle irradiation in HD. PMID:20019226

Primary cutaneous follicle center lymphoma with Hodgkin and Reed-Sternberg-like cells: a new histopathologic variant.  

PubMed

Primary cutaneous follicle center lymphoma (PCFCL) is the most frequent cutaneous B-cell lymphoma. A 62-year-old man presented with a solitary indolent subcutaneous nodule for 3 years duration, without other abnormalities. Histological examination showed lymphoproliferation with a nodular growth pattern characterized by fibrous collagen bands surrounding nodules. The nodules were composed of medium-sized centrocytes admixed with many large multilobulated and lacunar cells without eosinophils or granulomatous aspect. Hodgkin-like cells were CD30+, CD15+, PAX5+, OCT2+, BOB1+, MUM1+, Ki67+, Bcl6+ and focally CD20+ and EMA-, CD79a-, Bcl2- and CD10-. The medium-sized cells were CD20+, CD79a+, Bcl2+, Bcl6+ and CD10+, enmeshed in a network of CD21-positive follicular dendritic cells. Epstein-Barr virus detection was negative. Interphase fluorescence in situ hybridization showed the absence of BCL2 or BCL6 rearrangement. In such a case, the presence of Hodgkin-like cells intermixed with the tumor population may result in a pitfall diagnosis of classical Hodgkin lymphoma (CHL). Differential diagnoses to be ruled out are secondary or primary skin localization of rather CHL, or systemic follicular lymphoma. Several clinical, radiological, histological, immunohistochemical and molecular arguments indicated the diagnosis of PCFCL. To our knowledge, this is the first report of PCFCL with Hodgkin-like cells. PMID:25099172

Evaluation of Occupational Risk Factors in Non-Hodgkin Lymphoma and Hodgkin's Disease in Iranian Men  

PubMed Central

Background Lymphoma is a malignancy, arises from lymphoid tissue. Nowadays, it is the ninth most common cancer in Iran. The risk factors of malignant lymphomas have not well determined, but since 20 years ago till now, too many epidemiological researches have been concerning either Non-Hodgkin Lymphoma (NHL) or Hodgkin's Disease (HD). It is a common usual hypothesis that idiosyncratic reaction to common physical, chemical, and viral agents could lead to lymphoma without obvious immune deficiency. Some occupations has reported to cause increasing "NHL" risks, such as rubber industry, veterinaries, uranium mining, metal working, asbestos exposing, farming, textile industry, and benzene exposing. The roles of ionizing radiation, benzene and other environmental agents have not been clear, because of the lack of confirmed evidences for relation between the occupational and environmental agents with "HD". Methods A case-control study with 150 cases of malignant lymphoma and 150 controls have performed in Tehran. Data have selected through face-to-face interviews about the medical and occupational histories. Results In this study, there was a significantly increased risk for Non-Hodgkin Lymphoma in these occupations; welders, metal workers, founders, aluminium workers OR=4.6 [Confidence Interval (CI): 1.47-14.35] and increased risk for Hodgkin's Disease in drivers OR=2.34 [(CI):0.86-6.35]. We have found out decreased NHL risk in office workers OR=0.54 [(CI):0.29-1.02] and also found out a non-significant increased NHL risk in farmers OR=1.58 [(CI):0.82-3.03]. In this study, we have found no relation between smoking and HD, or NHL. Conclusion The results of this study suggest that several occupations could alter the risk of Non-Hodgkin Lymphoma and Hodgkin's Disease.

Ferritin, a Hodgkin's Disease Associated Antigen  

PubMed Central

Antigens which exist in high frequency in tumor tissues of patients with Hodgkin's disease have been obtained in relatively concentrated form by gel chromatography procedures. Further purification and analysis of these antigens performed in the present study have demonstrated that the antigen of fast electrophoretic mobility (F-antigen) is normal tissue ferritin. The identification of F-antigen as ferritin has been made on the basis of comparative physicochemical and immunological analyses of purified F-antigen and normal ferritin. Thus, F-antigen was found to contain iron and to be similar to ferritin in molecular weight, amino-acid composition, electrophoretic mobility, isoelectric distribution, and immunological reactivity. Absorption of a monospecific heterologous anti-F antiserum with normal tissue ferritin completely removed all anti-F antibody activity. Moreover, the absorption of polyspecific heterologous antiserum to crude Hodgkin's extracts, which contains antibodies reacting with F-antigen, the slower migrating S-antigen, and a third specificity present in lysates of normal peripheral blood lymphocytes (PL-antigen), with ferritin, removed only anti-F activity, thus distinguishing the S- and PL-antigens from ferritin. The existence of ferritin in high quantities in serum of Hodgkin's disease patients may provide a tool of potential diagnostic and prognostic importance in the management of this disease.

Lymphocyte depleted Hodgkin lymphoma: an evaluation with immunophenotyping and genetic analysis.  

PubMed

Lymphocyte depleted classical Hodgkin lymphoma (LDHL) is a vanishing category of classical Hodgkin lymphoma (CHL); many cases previously placed in this category are now recognised as diffuse large B-cell lymphoma (DLBCL), anaplastic large-cell lymphoma (ALCL), or nodular sclerosis CHL with lymphocyte depletion. In addition, the recent recognition of high grade B-cell lymphomas intermediate between DLBCL and CHL (grey-zone lymphomas) raises the question of whether LDHL exists at all as a category of CHL. We studied eight cases that fulfilled diagnostic criteria of LDHL according to the 2008 WHO Classification. The cases involved lymph nodes (7 cases) and pleura (1 case) from four males and four females (age 30-71 years; median 62 years). All tumors contained numerous Hodgkin-Reed-Sternberg (HRS) cells, fibroblasts and histiocytes and scattered lymphocytes. In three cases the tumors had a more diffuse fibrotic appearance, while in five cases they appeared reticular and anaplastic. Neoplastic cells in all cases expressed CD30, CD15, fascin, weak PAX5 and MUM-1 and lacked CD45, Alk-1, EMA, CD3, CD68, Mart-1 and cytokeratin. Oct.2 and/or Bob-1 were expressed in all cases. Two cases variably expressed CD20 but were CD79a negative. Four cases were positive for EBV. All the four cases with adequate DNA had clonally rearranged IGH genes. The combined morphologic, immunophenotypic and molecular genetic features of this group of cases distinguish LDHL from other disease entities, including grey-zone lymphomas. PMID:19455461

Development of non-Hodgkin's lymphoma following therapy for Hodgkin's disease  

SciTech Connect

Three patients developed non-Hodgkin's lymphoma (NHL) 3 to 6 years after treatment for Hodgkin's disease (HD). In no instance was there evidence of recurrence of HD following the initial chemotherapy or radiotherapy. None of these patients had received both radiation therapy and chemotherapy. All patients responded well to conventional chemotherapy for NHL and are alive at 23 +, 37 +, and 65+ months after that secondary diagnosis. This report, when coupled with at least ten other such reported patients, suggests that NHL may be a relatively uncommon but significant complication of therapy for HD and must be distinguished for recurrence of HD.

Identification of stromal proteins overexpressed in nodular sclerosis Hodgkin lymphoma.  

PubMed

Hodgkin lymphoma (HL) represents a category of lymphoid neoplasms with unique features, notably the usual scarcity of tumour cells in involved tissues. The most common subtype of classical HL, nodular sclerosis HL, characteristically comprises abundant fibrous tissue stroma. Little information is available about the protein composition of the stromal environment from HL. Moreover, the identification of valid protein targets, specifically and abundantly expressed in HL, would be of utmost importance for targeted therapies and imaging, yet the biomarkers must necessarily be accessible from the bloodstream. To characterize HL stroma and to identify potentially accessible proteins, we used a chemical proteomic approach, consisting in the labelling of accessible proteins and their subsequent purification and identification by mass spectrometry. We performed an analysis of potentially accessible proteins in lymph node biopsies from HL and reactive lymphoid tissues, and in total, more than 1400 proteins were identified in 7 samples. We have identified several extracellular matrix proteins overexpressed in HL, such as versican, fibulin-1, periostin, and other proteins such as S100-A8. These proteins were validated by immunohistochemistry on a larger series of biopsy samples, and bear the potential to become targets for antibody-based anti-cancer therapies. PMID:21975223

Discrete epithelioid cells: useful clue to Hodgkin's disease cytodiagnosis.  

PubMed

Diagnosis of Hodgkin's disease is made with more confidence than diagnosis of non-Hodgkin's lymphoma on cytology. This study was undertaken to describe the presence of granulomas and a new cytologic feature, discrete epithelioid cells (DECs), in smears from Hodgkin's disease. Fine-needle aspiration smears from 39 cases of biopsy-proven Hodgkin's disease, collected over a period of 43 months, were reviewed. Epithelioid granulomas were seen in 38.5% of the smears. DECs, which were noted in 70% of the cases, may be useful in raising the suspicion of Hodgkin's disease when other features are not evident; their presence should encourage the cytopathologist to obtain aspirations from other lymph nodes.

The Hodgkin-Huxley Heritage: From Channels to Circuits  

PubMed Central

The Hodgkin-Huxley studies of the action potential, published 60 years ago, are a central pillar of modern neuroscience research, ranging from molecular investigations of the structural basis of ion channel function to the computational implications at circuit level. In this Symposium Review, we aim to demonstrate the ongoing impact of Hodgkin’s and Huxley’s ideas. The Hodgkin-Huxley model established a framework in which to describe the structural and functional properties of ion channels, including the mechanisms of ion permeation, selectivity, and gating. At a cellular level, the model is used to understand the conditions that control both the rate and timing of action potentials, essential for neural encoding of information. Finally, the Hodgkin-Huxley formalism is central to computational neuroscience to understand both neuronal integration and circuit level information processing, and how these mechanisms might have evolved to minimize energy cost.

Non-Hodgkin's Lymphoma in Buccal Vestibule -Case Report  

PubMed Central

Lymphomas are malignant neoplasms arising from lymphocytes B cell or T cell that affects mainly lymph nodes, spleen and other non hematopoietic tissues. They are classified as Hodgkin’s lymphoma (HL) and non-Hodgkin’s lymphoma (NHL). Diffuse large B-cell lymphoma (DLBL) is the most common variant of non-Hodgkin’s lymphomas and frequently involves extranodal sites. In the oral soft tissues lesions can occur as hard and diffuse tumors involving oral vestibule, gums and posterior region of the hard palate. Most lymphomas, including DLBL arise from B cells are characterized by diffuse population of large cells with cleaved or non cleaved oval nuclei. Both histopathlogical and immunohistochemical (IHC) analysis were strongly advisable for proper management and prognosis. We hereby report a rare case of Diffuse large B-cell variant of non-Hodgkin’s lymphoma in a male patient of age 50yrs in left upper buccal vestibule. PMID:25302245

Curcuma Contra Cancer? Curcumin and Hodgkin's Lymphoma.  

PubMed

Curcumin, a phytochemical isolated from curcuma plants which are used as coloring ingredient for the preparation of curry powder, has several activities which suggest that it might be an interesting drug for the treatment or prevention of cancer. Curcumin targets different pathways which are involved in the malignant phenotype of tumor cells, including the nuclear factor kappa B (NFKB) pathway. This pathway is deregulated in multiple tumor entities, including Hodgkin's lymphoma (HL). Indeed, curcumin can inhibit growth of HL cell lines and increases the sensitivity of these cells for cisplatin. In this review we summarize curcumin activities with special focus on possible activities against HL cells. PMID:24665206

The treatment of measles pneumonitis in immunocompromised adults is not established. We describe a patient with Hodgkin's lymphoma who developed acute pneumonia during a measles infection. On day 13, intravenous ribavirin and immunoglobulins were administrated. On day 18, the patient developed acute respiratory failure. An examination of transbronchial pulmonary biopsies showed Warthin-Finkeldey giant cells that are pathognomonic of measles pneumonitis. The patient died despite aggressive supportive care. Our case and a review of literature show that measles pneumonitis is routinely fatal in patients with cancer. We suggest that antiviral drugs should be considered as soon as the diagnosis has been established. PMID:24105383

Second cancers following non-Hodgkin's lymphoma  

SciTech Connect

The risk of second malignancies following non-Hodgkin's lymphoma (NHL) was estimated in 29,153 patients diagnosed with NHL between 1973 and 1987 in one of nine areas participating in the National Cancer Institute's Surveillance, Epidemiology, and End Results Program. Compared with the general population, NHL patients were at a significantly increased risk of developing second cancers (observed/expected (O/E) = 1.18; O = 1231). The O/E ratio increased significantly with time to reach 1.77 in 10-year survivors. Significant excesses were noted for acute nonlymphocytic leukemia (O/E = 2.88), cancers of the bladder (O/E = 1.30), kidney (O/E = 1.47), and lung (O/E = 1.57), malignant melanoma (O/E = 2.44), and Hodgkin's disease (O/E = 4.16). Chemotherapy appeared related to subsequent acute nonlymphocytic leukemia (ANLL) and bladder cancer. Radiation therapy was associated with ANLL and possibly cancers of the lung, bladder, and bone. Malignant melanoma was not clearly related to initial NHL treatment.

Four cases of thyroidectomy for suspected thyroid carcinoma after previous irradiation for Hodgkin's or non-Hodgkin's lymphoma are reviewed. The patients ranged in age from 18 to 33 years at the time of thyroid surgery with an average latency period of 12 years (range, 8-20 years) from radiation therapy to thyroidectomy. All patients had a clinically palpable thyroid nodule, and pathologically showed a pattern of multiple adenomatous nodules with cytologic atypia. The microscopic changes were sufficiently striking to cause the primary pathologist to request consultation to rule out thyroid carcinoma in each case. Fine-needle aspiration was performed in one case and suggested a thyroid neoplasm. The pathologic findings are reviewed and distinction of this lesion from thyroid carcinoma is discussed.

[Diagnosis and treatment of primary testicular non-Hodgkin lymphoma].  

PubMed

The primary testicular non-Hodgkin lymphoma, which has been first described in 1866, is a very uncommon type of urological neoplasia occuring mostly in the elderly ages. It only gives 5% of the testicular tumors, 2% of extranodal lymphomas, and barely 1% of all non-Hodgkin diseases. Patients with testicular non-Hodgkin lymphomas need prompt multidisciplinary aid because without treatment the outcome can be unfavorable. The authors discuss the attributes, diagnostic modalities and treatment options of the primary testicular non-Hodgkin lymphoma and present a case of a 68-year-old patient who underwent orchiectomy, chemo- and radiotherapy after having been diagnosed with the tumor. The follow-up PET-CT and cerebrospinal fluid analysis found no further sign of the disease, and complete remission has been achieved. PMID:24389323

Classical QGP : IV. Thermodynamics  

E-print Network

We construct the equation of a state of the classical QGP valid for all values of Gamma=V/K, the ratio of the mean Coulomb to kinetic energy. By enforcing the Gibbs relations, we derive the pertinent pressure and entropy densities for all Gamma. For the case of an SU(2) classical gluonic plasma our results compare well with lattice simulations. We show that the strongly coupled component of the classical QGP contributes significantly to the bulk thermodynamics across T_c.

Combination chemotherapy of Hodgkin's disease in children.  

PubMed

Forty-five children with advanced Hodgkin's disease (stages III and IV) received combination chemotherapy in three schedules: MOPP (mustargen, Oncovin, procarbazine, prednisolone); COPP (cyclophosphamide was substituted for mustargen); and CVPP (cyclophosphamide, vinblastine, procarbazine, prednisone). The results showed the efficacy of all drug combinations (93% complete and partial remissions). However, the superiority of the MOPP program in prolonging the duration of the complete remission rate was demonstrated. Of 29 patients who showed complete response, 24 continued in complete remission from 8 to 53 months (median duration, 21 months). The other five patients relapsed within 2 to 6 months. Thirty-six of the 45 treated patients are still alive after an average period of follow-up of 19 months. The nine patients who died were followed for an average of seven months. The histologic type, prior chemotherapy, and the age of the patients influenced the results of treatment. The role of maintenance therapy is not discussed in this series PMID:991072

Fermions from classical statistics  

SciTech Connect

We describe fermions in terms of a classical statistical ensemble. The states {tau} of this ensemble are characterized by a sequence of values one or zero or a corresponding set of two-level observables. Every classical probability distribution can be associated to a quantum state for fermions. If the time evolution of the classical probabilities p{sub {tau}} amounts to a rotation of the wave function q{sub {tau}}(t)={+-}{radical}(p{sub {tau}}(t)), we infer the unitary time evolution of a quantum system of fermions according to a Schroedinger equation. We establish how such classical statistical ensembles can be mapped to Grassmann functional integrals. Quantum field theories for fermions arise for a suitable time evolution of classical probabilities for generalized Ising models.

IMP3 as a supplemental diagnostic marker for Hodgkin lymphoma.  

PubMed

Insulin-like growth factor II mRNA-binding protein 3 (IMP3) is ubiquitously expressed in embryos, mediating organogenesis, RNA trafficking, and cell growth, and is generally down-regulated in adult tissue. However, IMP3 has recently been shown to be overexpressed in some malignant epithelial neoplasms and to be a useful diagnostic and/or prognostic biomarker for several carcinomas. To determine whether IMP3 might also be an accurate biomarker of Hodgkin lymphoma, we examined 81 Hodgkin lymphomas for immunoreactivity to IMP3 as compared to commonly used markers such as CD30, CD15, PAX5, and MUM1. Consequently, in 98.8% (80/81) of Hodgkin lymphomas, the malignant Hodgkin and Reed-Sternberg cells were selectively reactive for IMP3, with 72.8% (59/81) of the tumors showing strong, diffuse cytoplasmic staining. Positive staining of the Hodgkin lymphomas was also seen for CD30 (82.7%, 67/81), CD15 (65.4%, 53/81), PAX5 (84.0%, 68/81), and MUM1 85.2% (69/81), but significantly fewer cells showed strong staining intensity for CD30 (32.1%, 26/81), CD15 (17.3%, 14/81), PAX5 (12.3%, 10/81), and MUM1 (29.6%, 24/81). Furthermore, the IMP3 staining was selectively restricted to Hodgkin and Reed-Sternberg cells, with a clearly negative background, and complementary to CD30 staining. Our findings show that IMP3 may be a useful diagnostic marker of Hodgkin lymphoma, helping to improve diagnostic accuracy for this malignancy. PMID:23845468

Whole-body FDG-PET imaging for staging of Hodgkin`s disease and lymphoma  

SciTech Connect

Accurate staging of Hodgkin`s disease (HD) and non-Hodgkin`s lymphoma (NHL) is important for treatment management. In this study, the utility of 2-[{sup 18}F]fluoro-2-deoxy-D-glucose (FDG) wholebody PET was evaluated as an imaging modality for initial staging or restaging of 7 HD and 11 NHL patients. Whole-body PET-based staging results were compared to the patient`s clinical stage based on conventional staging studies, which included combinations of CT of the chest, abdomen and pelvis, MRI scans, gallium scans, lymphangiograms, staging laparatomies and bone scans. Accurate staging was performed in 17 of 18 patients using a whole-body PET-based staging algorithm compared to the conventional staging algorithm in 15 of 18 patients. In 5 of 18 patients, whole-body PET-based staging showed additional lesions not detected by conventional staging modalities, whereas conventional staging demonstrated additional lesions in 4 of 18 patients not detected by whole-body PET. The total cost of conventional staging was $66,292 for 16 CT chest scans, 16 CT abdominal/pelvis scans, three limited MRI scans, four bone scans, give gallium scans, two laparotomies and one lymphangiogram. In contrast, scans cost $36,250 for 18 whole-body PET studies and additional selected correlative studies: one plain film radiograph, one limited CT, one bone marrow san, one upper GI and one endoscopy. A whole-body FDG-PET-based staging algorithm may be an accurate and cost-effective method for staging or restaging HD and NHL. 10 refs., 7 figs., 2 tabs.

LACE-conditioned autologous stem cell transplantation for relapsed or refractory Hodgkin's lymphoma: treatment outcome and risk factor analysis in 67 patients from a single centre.  

PubMed

High-dose chemotherapy followed by autologous stem cell transplantation (ASCT) is a recognized treatment option for patients with relapsed Hodgkin's lymphoma. We have analysed 67 patients who underwent ASCT after LACE (lomustine (CCNU), cytarabine (Ara-C), cyclophosphamide, etoposide) conditioning for relapsed (n=61) or primary refractory (n=6) Hodgkin's lymphoma. The 100-day treatment-related mortality was 3%. With a median follow-up of 67 months (range 3.3-161.0) the probabilities of overall survival (OS) and progression-free survival (PFS) at 5 years were 68 and 64%, respectively. Probabilities for OS and PFS at 5 years for patients with chemosensitive relapse (n=40) were 81 and 78% versus 50 and 35%, respectively, for patients (n=27) with chemoresistant relapse (P=0.012 for OS, P=0.002 for PFS). In multivariate analysis mixed cellularity classical or lymphocyte-depleted classical histology subtype and haemoglobin level of 10 g/dl or less at the time of ASCT were identified as risk factors for worse OS, whereas stage III or IV disease at diagnosis and disease status at ASCT other than complete or partial remission predicted inferior PFS. LACE followed by ASCT is an effective treatment for the majority of patients with chemosensitive relapsed Hodgkin's lymphoma and a proportion of chemorefractory patients also benefit. PMID:17115062

Second malignant lesions after therapy for Hodgkin's disease  

SciTech Connect

Among 169 adult pathologically staged patients with Hodgkin's disease who were treated at the Mayo Clinic between 1974 and 1978, four cases of second malignant lesions were identified. The median duration of follow-up after diagnosis for the entire population was 4.1 years. Of the 169 patients, 73 received irradiation only, 19 received chemotherapy only, and 77 received both chemotherapy and radiation therapy. In all four patients with second malignant lesions, Hodgkin's disease was in apparent remission at the time of diagnosis of the second tumor. These four patients had received either total nodal irradiation or six or more cycles of chemotherapy as initial treatment (and one of them had received both treatment modalities). Thus, intensive therapy might be hypothesized to have played a role in the development of the second malignant tumor. The development of non-Hodgkin's lymphoma within a previously irradiated field after treatment of Hodgkin's disease with radiation therapy only is not know to have been reported previously. Although further studies with longer follow-up should be conducted, this analysis supports a definite risk for development of a second malignant lesion not only after combined-modality treatment or chemotherapy for Hodgkin's disease but also after irradiation only.

Primary nasopharyngeal Hodgkin's disease: case report and literature review  

PubMed Central

Introduction Primary Hodgkin's disease of the nasopharynx is a rare and uncommon event. It has a relatively favorable prognosis and represents less than 1% of all documented cases of Hodgkin's disease. Case presentation A 40-year-old Arabic man presented initially with bilateral nasal obstruction, which was then followed by a significant involvement of his bilateral cervical lymph nodes. His nasopharyngeal biopsy together with immunohistochemistry analysis showed negative expressions of CD15, CD20 and CD3, but positive expressions of CD30 and epithelial membrane antigen. This confirmed the diagnosis of nasopharyngeal Hodgkin's disease of a mixed cellularity subtype. The disease was at stage IIEA. Our patient received four cycles of chemotherapy, which yielded a 75% response. This was followed by irradiation of his Waldeyer's ring and supraclavicular lymph nodes. He remains in good local control after 30 months of follow-up. Conclusion The literature review and our case report discuss the optimal management of this rare and atypical localization of Hodgkin's disease, which should be differentiated from lymphoproliferations associated with Epstein-Barr virus and non-Hodgkin's lymphoma.

The classical Bloch equations  

NASA Astrophysics Data System (ADS)

Coherent control of a quantum mechanical two-level system is at the heart of magnetic resonance imaging, quantum information processing, and quantum optics. Among the most prominent phenomena in quantum coherent control are Rabi oscillations, Ramsey fringes, and Hahn echoes. We demonstrate that these phenomena can be derived classically by use of a simple coupled-harmonic-oscillator model. The classical problem can be cast in a form that is formally equivalent to the quantum mechanical Bloch equations with the exception that the longitudinal and the transverse relaxation times (T1 and T2) are equal. The classical analysis is intuitive and well suited for familiarizing students with the basic concepts of quantum coherent control, while at the same time highlighting the fundamental differences between classical and quantum theories.

Tree Biomass Estimation of Chinese fir (Cunninghamia lanceolata) Based on Bayesian Method  

PubMed Central

Chinese fir (Cunninghamia lanceolata (Lamb.) Hook.) is the most important conifer species for timber production with huge distribution area in southern China. Accurate estimation of biomass is required for accounting and monitoring Chinese forest carbon stocking. In the study, allometric equation was used to analyze tree biomass of Chinese fir. The common methods for estimating allometric model have taken the classical approach based on the frequency interpretation of probability. However, many different biotic and abiotic factors introduce variability in Chinese fir biomass model, suggesting that parameters of biomass model are better represented by probability distributions rather than fixed values as classical method. To deal with the problem, Bayesian method was used for estimating Chinese fir biomass model. In the Bayesian framework, two priors were introduced: non-informative priors and informative priors. For informative priors, 32 biomass equations of Chinese fir were collected from published literature in the paper. The parameter distributions from published literature were regarded as prior distributions in Bayesian model for estimating Chinese fir biomass. Therefore, the Bayesian method with informative priors was better than non-informative priors and classical method, which provides a reasonable method for estimating Chinese fir biomass.

The Functional TP53 rs1042522 and MDM4 rs4245739 Genetic Variants Contribute to Non-Hodgkin Lymphoma Risk  

PubMed Central

As a heterogeneous kind of malignances, Non-Hodgkin lymphoma (NHL) is the most common hematologic cancer worldwide with the significantly increased morbidity in China. Accumulated evidences demonstrated that oncoprotein MDM4 plays a crucial role in the TP53 tumor suppressor signaling pathway. An rs4245739 A>C polymorphism locating in the MDM4 3?-untranslated region creates a miR-191 target site and results in allele-specific MDM4 expression. In this study, we examined the association between this polymorphism as well as the TP53 Arg72Pro (rs1042522 G>C) genetic variant and Non-Hodgkin Lymphoma (NHL) risk in a Chinese Han population. Genotypes were determined in 200 NHL cases and 400 controls. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated by logistic regression. We found significantly increased NHL risk among carriers of the TP53 72Pro allele compared with those with the 72Arg allele (P?=?0.002 for the Pro/Pro genotype). We also observed a significantly decreased NHL risks among carriers of the MDM4 rs4245739 C allele compared with those with the A allele in Chinese (P?=?0.014 for the AC genotype). Stratified analyses revealed the associations between these SNPs and NHL risk are especially noteworthy in young or male individuals. Additionally, the associations are much pronounced in NHL patients with B-cell lymphomas or grade 3 or 4 disease. Our results indicate that the TP53 Arg72Pro and the MDM4 rs4245739 polymorphisms contribute to NHL susceptibility and support the hypothesis that genetic variants in the TP53 pathway genes can act as important modifiers of NHL risk.

Deregulated FOX genes in Hodgkin lymphoma.  

PubMed

FOX genes encode transcription factors which regulate basic developmental processes during embryogenesis and in the adult. Several FOX genes show deregulated expression in particular malignancies, representing oncogenes or tumor suppressors. Here, we screened six Hodgkin lymphoma (HL) cell lines for FOX gene activity by comparative microarray profiling, revealing overexpression of FOXC1 and FOXD1, and reduced transcription of FOXN3, FOXO1, and FOXP1. In silico expression analyses of these FOX gene candidates in HL patient samples supported the cell line data. Chromosomal analyses demonstrated an amplification of the FOXC1 locus at 6p25 and a gain of the FOXR2 locus at Xp11, indicting genomic aberrations for their upregulation. Comparative expression profiling and ensuing stimulation experiments revealed implementation of the TGF?- and WNT-signaling pathways in deregulation of FOXD1 and FOXN3. Functional analysis of FOXP1 implicated miR9 and miR34a as upstream regulators and PAX5, TCF3, and RAG2 as downstream targets. A similar exercise for FOXC1 revealed repression of MSX1 and activation of IPO7, both mediating inhibition of the B-cell specific homeobox gene ZHX2. Taken together, our data show that aberrantly expressed FOX genes and their downstream targets are involved in the pathogenesis of HL via deregulation of B-cell differentiation and may represent useful diagnostic markers and/or therapeutic targets. © 2014 Wiley Periodicals, Inc.

NHL is a heterogeneous group of malignancies with multiple subtypes, each of which has distinct morphologic, immunophenotypic, and clinical features. Identifying the risk factors for NHL may improve our understanding of the underlying biological mechanisms and have an impact on clinical practice. Areas covered This article provides a review of several aspects of NHL, including epidemiology and subtype classification, clinical, environmental, genetic, and genomic risk factors identified for etiology and prognosis, and available statistical and bioinformatics tools for identification of genetic and genomic risk factors from the analysis of high-throughput studies. Expert opinion Multiple clinical and environmental risk factors have been identified. However, they have failed to provide practically effective prediction. Genetic and genomic risk factors identified from high-throughput studies have suffered a lack of reproducibility. The identification of genetic/genomic risk factors demands innovative statistical and bioinformatics tools. Although multiple analysis methods have been developed, there is still room for improvement. There is a critical need for well-designed, prospective, large-scale pangenomic studies. PMID:22059093

Cellular telephones and non-Hodgkin lymphoma.  

PubMed

Dramatic increase in hand-held cellular telephone use since the 1980s and excess risk of lymphoproliferative malignancies associated with radio-frequency radiation (RFR) exposures in epidemiological and experimental studies motivated assessment of cellular telephones within a comprehensive US case-control investigation of non-Hodgkin lymphoma (NHL). A questionnaire ascertained cellular telephone use in 551 NHL cases and 462 frequency-matched population controls. Compared to persons who had never used cellular telephones, risks were not increased among individuals whose lifetime use was fewer than 10 (odds ratio (OR) = 0.9, 95% confidence intervals (CI): 0.6, 1.3), 10-100 (OR = 1.0, 95 % CI: 0.7, 1.5) or more than 100 times (e.g., regular users, OR = 0.9, 95% CI: 0.6, 1.4). Among regular users compared to those who had never used hand-held cellular telephones, risks of NHL were not significantly associated with minutes per week, duration, cumulative lifetime or year of first use, although NHL was non-significantly higher in men who used cellular telephones for more than 8 years. Little evidence linked use of cellular telephones with total, diffuse large B-cell lymphoma or follicular NHL. These findings must be interpreted in the context of less than 5% of the population reporting duration of use of 6 or more years or lifetime cumulative use of 200 or more hours. PMID:16894556

Hodgkin's Lymphoma Therapy: Past, Present, and Future  

PubMed Central

Importance of the field The treatment of Hodgkin lymphoma (HL) with the use of radiotherapy and systemic chemotherapy has been one of the success stories of modern oncology. HL therapy has been the paradigm for the systematic evaluation of different curative modalities resulting in cure for the majority of patients. The current focus is on designing initial therapeutic strategies which retain efficacy and minimize long-term toxicity. Appropriate use of pathologic, clinical, biologic and radiologic prognostic factors in identification of aggressive HL is paramount in designing a successful therapeutic strategy. Areas covered in this review This review addresses the current and future use of prognostic tools, including PET scanning and other biomarkers, in identifying patients with aggressive HL with reference to publications from the last two decades. The current standard approaches with the use of combined modality therapy and systemic chemotherapy as well as the promising role of future response-adapted strategies is reviewed. What the reader will gain The reader will obtain a comprehensive review of risk assessment strategies as well as current and investigational therapeutic approaches in the management of HL. Take home message In HL, appropriate utilization of risk assessment strategies is required to maximize therapeutic outcomes while minimizing toxicity, especially long-term toxicity. Response-adapted therapy utilizing PET has the potential to profoundly improve the therapeutic landscape in HL. PMID:21050034

Spectrum of immunodeficiencies with Hodgkin's disease.  

PubMed Central

The role of six suppressor mechanisms upon T and B cell responses was studied on 17 untreated patients with Hodgkin's disease. Proliferative hyporesponsiveness to mitogen was greatly impaired in 8 of the 13 patients. 10 of these patients had an excessive degree of suppression by cells that adhered to foreign surfaces. Suppression by adherent cells correlated with impairment of proliferative responses and, in some instances, suppression was largely inhibited with indomethacin. Likewise, adherent cells suppressed immunoglobulin synthesis. A correlation was evident between suppression of T and B cell responses by adherent mononuclear leukocytes from individual patients. This suppression coincided with elevated percentages of monocytes in the patient mononuclear cell preparations. This excess of monocytes was not the result of a circulating monocytosis. The monocyte excess may have been acquired during isopyknic cell separation. A second form of suppression was observed in 5 of the 11 patients affected by a lymphocyte that neither adhered to glass wool nor required preactivation. It did not inhibit allogeneic lymphocytes, which contrasts with the suppressor abnormality of monocytoid cells. PMID:6448268

Changing patterns of relapse in Hodgkin's disease.  

PubMed Central

The patterns of early and late relapses (those occurring later than 3 years after diagnosis) in 432 patients achieving complete remission after treatment for stage I and II Hodgkin's disease at the Royal Marsden Hospital between 1964 and 1983 were studied to identify factors predicting for late relapse. The incidence of early relapse has fallen progressively in recent treatment eras as staging procedures and management have improved but in contrast there has been no decrease in the risk of late relapse. The incidence of late relapse was greater in patients treated with radiotherapy rather than combined modality therapy (P less than 0.05). However, patients who were clinically staged and treated with combined modality therapy retained as high a risk of relapse between 3 and 6 years as in years 2 and 3. The risk of late relapse was also greater in patients with stage II disease and in those without B symptoms at presentation. Patients falling into the higher risk categories for late relapse require continued close follow-up beyond 3 years to monitor for possible relapse. PMID:2765370

A crash course in Chinese herbology for the psychopharmocological prescriber.  

PubMed

Given the unparalleled popularity of botanicals in the United States, it is safe to say that almost every psychopharmacological prescriber will see some patients using Chinese herbs. Data show that between 36% and 42% of Americans use complementary and alternative medicine (CAM) each year and that persons suffering from depression and anxiety (67%) use CAM services significantly more than do their nonanxious and nondepressed counterparts (39%). This article gives an overview of several classical Chinese medical single herbs and herbal formulas commonly used for persons with psychiatric disorders and discusses some of the herbs that have the potential to interact with various pharmaceutical drugs. In addition, the article reviews scientific evidence and, at times, the lack thereof to validate the use of Chinese herbs and formulas in treating psychiatric conditions. Overall, the article seeks to prepare the pharmacological prescriber for working with patients concomitantly taking psychiatric medications and Chinese herbs. PMID:19968403

Hodgkin's Lymphoma Revealed by Hemophagocytic Lymphohistiocytosis in a Child  

PubMed Central

Hemophagocytic lymphohistiocytosis (HLH) is a severe life-threatening disorder, responsible for extensive phagocytosis of hematopoietic cells and causing a multisystem organ failure. If lymphomas are common causes of HLH, the association with Hodgkin's lymphoma is rarely described in children. We report a case of a 9-year-old boy presenting with HLH as an initial manifestation of Hodgkin's lymphoma. He has been suffering from persistent high fever, asthenia, weight loss, and hepatosplenomegaly with no lymphadenopathy. The diagnosis of HLH secondary to infectious disease was initially worn. The patient received high-dose intravenous immunoglobulin with broad-spectrum antibiotics. However, his state got worse with the onset of dry cough and pleural effusion. Histopathologic examination of pleural fluid showed the presence of Reed-Sternberg cells. The outcome was favorable after treatment by corticosteroid and chemotherapy. Hodgkin's lymphoma revealed by HLH is a source of delayed diagnosis and should be borne in mind in children. PMID:25328742

Female reproductive potential after treatment for Hodgkin's disease  

SciTech Connect

The probability of maintaining ovarian function, becoming pregnant, and delivering a normal child is important to young women anticipating successful therapy for Hodgkin's disease. In this study, reproductive function was retrospectively examined in 103 women 40 years old or younger who had undergone treatment for Hodgkin's disease with total-lymphoid irradiation (TLI) alone, combination chemotherapy, or combined TLI and chemotherapy. Infertility was directly related to gonadal exposure to therapy and to age at treatment. Twenty women became pregnant after receiving total-nodal irradiation or combination chemotherapy or both. No fetal wastage occurred, and no birth defects were seen in the 24 infants born to these women. Even after intensive treatment programs, women successfully treated for Hodgkin's disease have become pregnant and delivered phenotypically normal children.

Non-Hodgkin's lymphoma of maxillary sinus: An unusual presentation  

PubMed Central

Non-Hodgkin's Lymphoma (NHL) are a group of neoplasms that originate from the cells of the lymphoreticular system. Forty percent of Non-Hodgkin's lymphoma arises from extranodal sites. The nasal cavities and paranasal sinuses are rarely affected by primary NHL. Common primary extranodal sites of lymphomas include stomach, liver, soft tissue, dura, bone, intestine and bone marrow. Most patients present with rapidly enlarging masses, often with symptoms both locally and systemically (fever, recurrent night sweats, or weight loss). The vast majority of patients with localized disease are curable with combined modality therapy or combination chemotherapy alone. About 50% patients are cured with doxorubicin based combination chemotherapy and rituximab. An atypical case of extranodal Non-Hodgkin's lymphoma of maxillary sinus is discussed. PMID:23662270

Breast Cancer After Treatment of Hodgkin's Lymphoma: General Review  

SciTech Connect

The improved survival rates among patients with Hodgkin's lymphoma over the past few decades have come with increased incidence of second malignancies. One of the major concerns among female survivors is the significantly elevated risk of breast cancer that appears with extended follow-up. In this review, we include the published literature regarding the risk of breast cancer after irradiation for Hodgkin's lymphoma. We also present the possible long-term surveillance strategies and the optimal time to start screening these women. This could potentially help in early detection of secondary breast cancers and consequently improve outcomes. Furthermore, because of prior radiotherapy, the management of the breast cancer among this unique population has been controversial. We discuss the characteristics of breast cancer that occurs after Hodgkin's lymphoma and also treatment options that could be implemented.

Acoustical study of classical Peking Opera singing.  

PubMed

Acoustic characteristics of classical opera singing differ considerably between the Western and the Chinese cultures. Singers in the classical Peking opera tradition specialize on one out of a limited number of standard roles. Audio and electroglottograph signals were recorded for four performers of the Old Man role and three performers of the Colorful Face role. Recordings were made of the singers' speech and when they sang recitatives and songs from their roles. Sound pressure level, fundamental frequency, and spectrum characteristics were analyzed. Histograms showing the distribution of fundamental frequency showed marked peaks for the songs, suggesting a scale tone structure. Some of the intervals between these peaks were similar to those used in Western music. Vibrato rate was about 3.5Hz, that is, considerably slower than in Western classical singing. Spectra of vibrato-free tones contained unbroken series of harmonic partials sometimes reaching up to 17 000Hz. Long-term-average spectrum (LTAS) curves showed no trace of a singer's formant cluster. However, the Colorful Face role singers' LTAS showed a marked peak near 3300Hz, somewhat similar to that found in Western pop music singers. The mean LTAS spectrum slope between 700 and 6000Hz decreased by about 0.2dB/octave per dB of equivalent sound level. PMID:21621380

Classical dynamical localization.  

PubMed

We consider classical models of the kicked rotor type, with piecewise linear kicking potentials designed so that momentum changes only by multiples of a given constant. Their dynamics display quasilocalization of momentum, or quadratic growth of energy, depending on the arithmetic nature of the constant. Such purely classical features mimic paradigmatic features of the quantum kicked rotor, notably dynamical localization in momentum, or quantum resonances. We present a heuristic explanation, based on a classical phase space generalization of a well-known argument, that maps the quantum kicked rotor on a tight-binding model with disorder. Such results suggest reconsideration of generally accepted views that dynamical localization and quantum resonances are a pure result of quantum coherence. PMID:25379918

Toxicity of the Chinese herb mu tong (Aristolochia manshuriensis). What history tells us.  

PubMed

Plant sources of some traditional Chinese herbs may have changed over time. History records of herbal toxicity should be viewed critically when different plants might have been used under the same name in earlier eras. The current main source of the Chinese herb Mu Tong is Aristolochia manshuriensis. Examination of classical Chinese herbal literature revealed that until the mid 17th century the original source plants of Mu Tong had been several Akebia species. From the 17th century until the early 20th century Clematis species were the main source of Mu Tong. A manshuriensis has only been widely used since the 1950s. Renal failure due to ingestion of large doses of A. manshuriensis has been reported in China and other countries while no such toxicity has been recorded in traditional Chinese herbal texts. Documentation of traditional Chinese herbal literature should help to ensure the safe use of Chinese herbs. PMID:12503251

Here we focus on the amount of classical communication that is necessary to obtain non-classical fidelity in teleportation. We quantify the amount of classical communication that is sufficient for two one-bit and one two-bits noisy classical channels for non-classical fidelity and we also find the necessary amount of classical communication for isotropic transformation.

Season of birth and risk of Hodgkin and non-Hodgkin lymphoma.  

PubMed

Infectious etiologies have been hypothesized for Hodgkin and non-Hodgkin lymphoma (HL and NHL) in early life, but findings to date for specific lymphomas and periods of susceptibility are conflicting. We conducted the first national cohort study to examine whether season of birth, a proxy for infectious exposures in the first few months of life, is associated with HL or NHL in childhood through young adulthood. A total of 3,571,574 persons born in Sweden in 1973-2008 were followed up through 2009 to examine the association between season of birth and incidence of HL (943 cases) or NHL (936 cases). We found a sinusoidal pattern in NHL risk by season of birth (p?=?0.04), with peak risk occurring among birthdates in April. Relative to persons born in fall (September-November), odds ratios for NHL by season of birth were 1.25 [95% confidence interval (CI), 1.04-1.50; p?=?0.02] for spring (March-May), 1.22 (95% CI, 1.01-1.48; p?=?0.04) for summer (June-August) and 1.11 (95% CI, 0.91-1.35; p?=?0.29) for winter (December-February). These findings did not vary by sex, age at diagnosis or major subtypes. In contrast, there was no seasonal association between birthdate and risk of HL (p?=?0.78). In this large cohort study, birth in spring or summer was associated with increased risk of NHL (but not HL) in childhood through young adulthood, possibly related to immunologic effects of delayed infectious exposures compared with fall or winter birth. These findings suggest that immunologic responses in early infancy may play an important role in the development of NHL. PMID:24752499

Hodgkin's disease in childhood: therapy results in Argentina.  

PubMed

From 1940 to 1977, a total of 152 children aged 15 years or less with the histologic diagnosis of Hodgkin's disease were treated in Argentina. For analysis, these patients were placed into three periods which displayed the most outstanding changes in diagnostic workup and therapy. The periods are as follows: (1) 1940 to 1966 (43 children), (2) 1967 to 1972 (35 children), and (3) 1973 to 1977 (74 children). The patients were treated with extended field radiation therapy and followed by courses of cyclophosphamide-vinblastine-procarbazine-prednisone, with CCNU added (CCVPP) or not added (CVPP) in a randomized trial. The mean age of the whole group was 7.5 years (range 2 to 15 years) and there was a predominance of males (79%). Crude 6-year survival for the three periods were as follows: 1940 to 1966, 34%; 1967 to 1972, 50%; and 1973 to 1977, 79%. We conclude that (1) survival of Hodgkin's disease of childhood has shown a rather marked improvement during the last decade and this progress is probably due to the use of combined multidrug chemotherapy administered under collaborative controlled clinical trials; (2) preliminary evaluation of the results of CVPP and CCVPP therapy shows that the latter combination (CCVPP) neither increases the percent of patients achieving complete remission nor prolongs relapse-survival in Hodgkin's disease of childhood: and (3) all stages of childhood Hodgkin's disease can be successfully managed with multidrug chemotherapy alone.

Quantum particles from classical statistics  

E-print Network

Quantum particles and classical particles are described in a common setting of classical statistical physics. The property of a particle being "classical" or "quantum" ceases to be a basic conceptual difference. The dynamics differs, however, between quantum and classical particles. We describe position, motion and correlations of a quantum particle in terms of observables in a classical statistical ensemble. On the other side, we also construct explicitly the quantum formalism with wave function and Hamiltonian for classical particles. For a suitable time evolution of the classical probabilities and a suitable choice of observables all features of a quantum particle in a potential can be derived from classical statistics, including interference and tunneling. Besides conceptual advances, the treatment of classical and quantum particles in a common formalism could lead to interesting cross-fertilization between classical statistics and quantum physics.

Traditional Chinese Biotechnology  

NASA Astrophysics Data System (ADS)

The earliest industrial biotechnology originated in ancient China and developed into a vibrant industry in traditional Chinese liquor, rice wine, soy sauce, and vinegar. It is now a significant component of the Chinese economy valued annually at about 150 billion RMB. Although the production methods had existed and remained basically unchanged for centuries, modern developments in biotechnology and related fields in the last decades have greatly impacted on these industries and led to numerous technological innovations. In this chapter, the main biochemical processes and related technological innovations in traditional Chinese biotechnology are illustrated with recent advances in functional microbiology, microbial ecology, solid-state fermentation, enzymology, chemistry of impact flavor compounds, and improvements made to relevant traditional industrial facilities. Recent biotechnological advances in making Chinese liquor, rice wine, soy sauce, and vinegar are reviewed.

Association between simian virus 40 and non-Hodgkin lymphoma  

NASA Technical Reports Server (NTRS)

BACKGROUND: Non-Hodgkin lymphoma has increased in frequency over the past 30 years, and is a common cancer in HIV-1-infected patients. Although no definite risk factors have emerged, a viral cause has been postulated. Polyomaviruses are known to infect human beings and to induce tumours in laboratory animals. We aimed to identify which one of the three polyomaviruses able to infect human beings (simian virus 40 [SV40], JC virus, and BK virus) was associated with non-Hodgkin lymphoma. METHODS: We analysed systemic non-Hodgkin lymphoma from 76 HIV-1-infected and 78 HIV-1-uninfected patients, and non-malignant lymphoid samples from 79 HIV-1-positive and 107 HIV-1-negative patients without tumours; 54 colon and breast carcinoma samples served as cancer controls. We used PCR followed by Southern blot hybridisation and DNA sequence analysis to detect DNAs of polyomaviruses and herpesviruses. FINDINGS: Polyomavirus T antigen sequences, all of which were SV40-specific, were detected in 64 (42%) of 154 non-Hodgkin lymphomas, none of 186 non-malignant lymphoid samples, and none of 54 control cancers. This difference was similar for HIV-1-infected patients and HIV-1-uninfected patients alike. Few tumours were positive for both SV40 and Epstein-Barr virus. Human herpesvirus type 8 was not detected. SV40 sequences were found most frequently in diffuse large B-cell and follicular-type lymphomas. INTERPRETATION: SV40 is significantly associated with some types of non-Hodgkin lymphoma. These results add lymphomas to the types of human cancers associated with SV40.

Differentiation between sarcoidosis and Hodgkin's lymphoma based on mediastinal lymph node involvement pattern: Evaluation using spiral CT scan  

PubMed Central

Summary Background: The purpose of this study was to determine the specific and detailed anatomic sites and morphologic characteristics of mediastinal lymph nodes on spiral computed tomography for the purpose of differentiation between sarcoidosis and Hodgkin’s lymphoma. Material/Methods: Anatomical distribution of mediastinal lymph nodes on spiral CT was reviewed in 39 patients with sarcoidosis and 37 patients with Hodgkin’s lymphoma using the International Association for the Study of Lung Cancer (IASLC) lymph node map. Other morphologic features such as lymph node calcification or coalescence of adjacent lymph nodes were also compared. Results: Zone 10 was involved more often in sarcoidosis than in Hodgkin’s lymphoma. On the other hand, there was a higher tendency for presence of zone 1 and 3 as well as retrocrural and internal mammary lymphadenopathy in Hodgkin’s lymphoma than in sarcoidosis. Sarcoidosis presented with intranodal calcifications more often than Hodgkin’s lymphoma. Coalescence, pressure effect on adjacent structures and central cavitations were significantly more common in Hodgkin’s lymphoma. Conclusions: Findings of the present study indicate that specific anatomical distribution and morphological patterns of mediastinal lymph nodes, as demonstrated on spiral CT, can be useful in differentiating sarcoidosis from Hodgkin’s lymphoma.

Bidirectional coherent classical communication  

E-print Network

A unitary interaction coupling two parties enables quantum communication in both the forward and backward directions. Each communication capacity can be thought of as a tradeoff between the achievable rates of specific types of forward and backward communication. Our first result shows that for any bipartite unitary gate, coherent classical communication is no more difficult than classical communication -- they have the same achievable rate regions. Previously this result was known only for the unidirectional capacities (i.e., the boundaries of the tradeoff). We then relate the tradeoff curve for two-way coherent communication to the tradeoff for two-way quantum communication and the tradeoff for coherent communiation in one direction and quantum communication in the other.

Classical Language Instruction Project  

NSDL National Science Digital Library

Developed by Christian Wildberg at Princeton University, the Classical Language Instruction Project is designed to function as a resource for college undergraduates hoping to gain some insight into the pronunciation and elocution of ancient Greek and Latin. As the rationale for the Project states on the site: "There may be considerable debate among scholars about the most 'authentic' way to pronounce Greek or Latin; yet it is certain that the texts from the ancient world reflect a vivid and complex spoken language, not a lifeless code." With that in mind, the site features different classical scholars reading passages by a number of writers, including Homer, Plato, Virgil, Horace, Ovid, and Seneca. As the scholars read, students can follow along, view the passage in English, and pause the recording in order to develop an understanding of the text and its pronunciation. Finally, the site also includes a brief essay on rhythm and meter in Greek and Latin.

Classical Time Crystals  

E-print Network

We consider the possibility that classical dynamical systems display motion in their lowest energy state, forming a time analogue of crystalline spatial order. Challenges facing that idea are identified and overcome. We display arbitrary orbits of an angular variable as lowest-energy trajectories for nonsingular Lagrangian systems. Dynamics within orbits of broken symmetry provide a natural arena for formation of time crystals. We exhibit models of that kind, including a model with traveling density waves.

Classical group field theory  

NASA Astrophysics Data System (ADS)

The ordinary formalism for classical field theory is applied to dynamical group field theories. Focusing first on a local group field theory over one copy of SU(2) and then, on more involved nonlocal theories (colored and noncolored) defined over a tensor product of the same group, we address the issue of translation and dilatation symmetries and the corresponding Noether theorem. The energy momentum tensor and dilatation current are derived and their properties identified for each case.

Thyroid nodule as a first manifestation of Hodgkin lymphoma-report of two cases and literature review  

PubMed Central

Abstract Lymphomas account for less than 5% of thyroid malignant lesions. Vast majority of them are B-cell non-Hodgkin lymphomas (NHL), while Hodgkin lymphoma (HL) is extremely rare. Here we present two cases of HL, at baseline manifesting as a thyroid lesion. First patient, 29-year-old pregnant female, initially suspected for metastatic medullary thyroid cancer, was eventually diagnosed with mixed cellularity type of thyroid HL. Second patient, 22-year-old woman with suspicion of advanced thyroid cancer, was in the end diagnosed with an extra-lymphatic classical HL of the thyroid. In both cases, despite repeated fine-needle aspiration biopsy, cytological examination gave inconclusive or misleading results. On histopathological examination, thyroid tumor cells were positive for CD15 and CD30 antigen, which is typical for Reed-Sternberg cells. In the report authors also discuss difficulties in management as well as potential importance of novel methods such as FISH, PCR and other molecular techniques in diagnostics of thyroid lymphomas.

Positron emission tomography response at the time of autologous stem cell transplantation predicts outcome of patients with relapsed and/or refractory Hodgkin's lymphoma responding to prior salvage therapy  

PubMed Central

Background High-dose chemotherapy followed by autologous stem cell transplantation is the standard treatment for relapsed and/or refractory Hodgkin’s lymphoma although half of patients relapse after transplantation. Predictive factors, such as relapse within 12 months, Ann-Arbor stage at relapse, and relapse in previously irradiated fields are classically used to identify patients with poor outcome. Recently, 18-fluorodeoxyglucose positron emission tomography has emerged as a new method for providing information to predict outcome. The aim of this study was to confirm the predictive value of positron emission tomography status after salvage therapy and to compare single versus tandem autologous stem cell transplantation in patients with relapsed and/or refractory Hodgkin’s lymphoma. Design and Methods We report a series of 111 consecutive patients with treatment-sensitive relapsed and/or treatment-refractory Hodgkin’s lymphoma who achieved complete (positron emission tomography-negative group) or partial remission (positron emission tomography-positive group) at positron emission tomography evaluation after salvage chemotherapy and who underwent single or tandem autologous stem cell transplantation. Results Five-year overall and progression-free survival rates were 81% and 64%, respectively. There were significant differences in 5-year progression-free survival (79% versus 23%; P<0.001) and 5-year overall survival (90% versus 55%, P=0.001) between the positron emission tomography-negative and -positive groups, respectively. A complete response, as determined by positron emission tomography evaluation, after salvage therapy predicted significantly better 5-year overall survival rates in both intermediate (91% versus 50%; P=0.029) and unfavorable (89% versus 58%; P=0.026) risk subgroup analyses. In the positron emission tomography-positive subgroup, tandem transplantation improved 5-year progression-free survival from 0% (in the single transplantation group) to 43% (P=0.034). Multivariate analysis showed that positron emission tomography status (hazard ratio: 5.26 [2.57–10.73]) and tandem transplantation (hazard ratio: 0.39 [0.19–0.78]) but not risk factors at relapse (hazard ratio: 1.77 [0.80–3.92]) significantly influenced progression-free survival, while only tomography status significantly influenced overall survival (hazard ratio: 4.03 [1.38–11.75]). Conclusions In patients with relapsed/refractory Hodgkin’s lymphoma responding to prior salvage therapy, positron emission tomography response at time of autologous stem cell transplantation favorably influences outcome and enables identification of patients requiring single or tandem transplantation.

[The establishment, contributions, and final results of classical medical theories].  

PubMed

In countries with ancient civilization of both Eastern world and Western world, after the accumulation of clinical experiences of "empirical medicine" to a sufficient amount; in accordance of their primitive philosophical thoughts, classical medical theories were established to play an important role in guiding the clinical practice of "empirical medicine". Because of the similarity of philosophical thoughts all over the ancient world, their medical theories were also very similar to each other. After the scientific evaluation and improvement, Greek classical medical theories were inherited, refined or abandoned, and then eventually finished their historical mission. Chinese classical medical theories also need the similar scientific identification and improvement for flowing into the authorized main stream of modern medical theory systems to continuously apply their guiding roles in clinical practice. Scholars would better consider the developmental principles of cultures and sciences with a historical viewpoint and an open mind to avoid making mistakes from haughty and prejudice. PMID:23596779

Increased risk of lung cancer, non-Hodgkin's lymphoma, and leukemia following Hodgkin's disease  

SciTech Connect

The risk of second cancers (SCs) was assessed in 744 patients with Hodgkin's disease (HD) admitted to The Netherlands Cancer Institute from 1966 to 1983. Sixty-nine SCs were observed one month or more after start of first treatment. These included 14 cases of lung cancer, nine cases of non-Hodgkin's lymphoma (NHL), 16 cases of leukemia, and six cases of the myelodysplastic syndrome (MDS). The median interval between the diagnosis of HD and that of second lung cancer, NHL, and leukemia was 8.1, 13.3, and 5.7 years, respectively. The overall relative risks (RR) (observed/expected (O/E) ratios) of developing lung cancer, NHL, and leukemia were 4.9 (95% confidence limit (CL), 2.7 to 8.2), 31.0 (95% CL, 14.2 to 58.9) and 45.7 (95% CL, 26.1 to 74.2), respectively. At 15 years the cumulative risk of developing an SC amounted to 20.6% +/- 2.9%. The 15-year estimates of lung cancer, NHL, and leukemia were 6.2% +/- 1.9%, 5.9% +/- 2.1% and 6.3% +/- 1.7%, respectively. Increased lung cancer risk following HD has not frequently been clearly demonstrated before; that we were able to demonstrate such risk may be due to the completeness of follow-up over long periods that could be achieved in this study. Excess lung cancer risk was only noted in treatment regimens with radiotherapy (RT); also, all lung cancers arose in irradiation fields. Excess risk of leukemia was only found in treatment regimens involving chemotherapy (CT). For NHL, combined modality treatment was shown to be the most important risk factor. Risk of lung cancer and NHL increased with time since diagnosis. A time-dependent covariate analysis (Cox model) performed on leukemia and MDS showed an increasing risk with intensity of CT, age (greater than 40 years), and a splenectomy.

Paraneoplastic pruritus presenting with Hodgkin's lymphoma: a case report  

PubMed Central

Introduction Paraneoplastic pruritus is defined as pruritus that occurs before or during the natural evolution of a hematologic disease. The reported prevalence is 30% in patients with Hodgkin’s lymphoma. The severity of this pruritus has a very negative impact on patients’ quality of life. Very few studies have been made to examine the efficacy of pharmacological treatments for this type of pruritus. One drug that appears to be effective in this respect is off-label aprepitant, a neurokinin 1 receptor antagonist. Case presentation A 20-year-old Caucasian woman presented with lateral neck nodes, sweating, and pruritus and was diagnosed with stage IIB nodular sclerosis Hodgkin’s lymphoma. Throughout this period during the disease the pruritus was ever-present. Improvement was achieved with some of the chemotherapy treatments, but the symptom returned when the various treatments were withdrawn due to disease progression or poor tolerance. In the middle of the seventh year, she was admitted to our hospital with uncontrolled pruritus that resulted in severe lesions due to scratching. In response, aprepitant (off-label) 80mg/day was added to the chemotherapic treatment of the pruritus, after studying the various treatment options. She reported a score of 9 on a visual analogue scale for the pruritus, and a score of 3 on the Eastern Cooperative Oncology Group performance status scale of performance status. After two weeks of treatment with aprepitant, she reported a score of 5 on the visual analogue scale for the pruritus, and this improved to a score of 4 in a month, which allowed her to lead a better quality of life, with an Eastern Cooperative Oncology Group performance status score between 1 and 2. Conclusions Several cases and case series have been reported on the use of aprepitant for paraneoplastic pruritus, but none have referred to its use for Hodgkin’s lymphoma. A prospective study was carried out to evaluate the efficacy of this drug in refractory pruritus secondary to Sezary syndrome, and other authors have studied the effectiveness of aprepitant against pruritus, secondary to biological therapy with erlotinib. In our case report, treatment was started with daily doses of aprepitant 80mg. Pruritus improvement appeared to be attributable exclusively to the administration of aprepitant. PMID:25200537

A Tumor Antigen in Tissue Cultures Derived from Patients with Hodgkin's Disease  

PubMed Central

Pellets obtained from supernatant fluids of monolayer cultures of cells from patients with Hodgkin's disease were fractionated by isopycnic density sedimentation. Material in a peak of specific gravity 1.15-1.21 g/ml from two Hodgkin's disease cultures was used to immunize rabbits, and the antisera obtained in this manner were reacted by agar-gel diffusion and immunoelectrophoresis with antigens from the purified peaks and the unfractionated pellets of centrifuged culture medium from all the cultures. The antisera reacted with material from 9 of 10 lines derived from spleens of patients with Hodgkin's disease, 2 of 8 cell lines from histologically negative spleens from patients with Hodgkin's disease and with 3 of 6 lymphoma cell lines not diagnosed as Hodgkin's disease. The antisera did not react with 12 cell cultures prepared from normal adult and fetal spleen and thymus. The antigen from cultures from patients with Hodgkin's disease was not found in material sedimenting at lower specific gravities; it resisted Tweenether solubilization, and migrated as a single band by immunoelectrophoresis. The antigen was not found in disrupted, noncultured tumor cells from patients with Hodgkin's disease, and an antiserum against noncultured, minced tumor tissue did not react with the Hodgkin's disease tissue-culture material. No immunological relationship was found between the tissue culture antigen and Epstein-Barr, RD-114, or Rauscher murine leukemia viruses. The Hodgkin's disease antigen may be a tumorrelated antigen or a component of an oncogenic virus. Images PMID:4351181

Hodgkin's disease, the syndrome of enlarged lymph nodes associated with enlarged spleen, was described in 1832 on the basis of the gross appearance of the affected parts. The eponym entered the medical literature after repeated attempts by Dr. Samuel Wilks to credit Thomas Hodgkin with the priority of discovery. Today, this malady, also known by many other names, is recognized by microscopic examination of histological features. Hodgkin also described retroversion of the aortic valves with insufficiency in 1827 but Dr. Dominic Corrigan, whose report appeared in 1832, was credited with the eponym, despite efforts again by Wilks on behalf of Hodgkin.

Hodgkin lymphoma transformation of chronic lymphocytic leukemia/small lymphocytic lymphoma  

PubMed Central

Transformation to a large cell lymphoma may occur during the course of chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) in approximately 5% of the cases. This is known as Richter's transformation. A much less frequent transformation to Hodgkin lymphoma may occur. We report a case of CLL/SLL in which a transformation to Hodgkin lymphoma occurred, and we review previously published reports of this transformation. Transformation to Hodgkin lymphoma in CLL/SLL has a poor outcome compared to de novo cases of Hodgkin lymphoma. PMID:23382602

On the natural medical features of traditional Chinese medicine.  

PubMed

Heaven-human-earth Pattern (HHE) regarded as a crucial conception of traditional Chinese medicine (TCM) has been applied extensively in TCM diagnostics, etiology, acupuncture therapeutics, materia medica and herbal formula, etc. It associates closely with Chinese classic cosmology. Since ancient time of China, many cosmic phenomena have been introduced to prove or illustrate TCM theories. Moreover, the five-element theory has been proven to be in keeping with some modern approaches of life provenance and life evolution. As a result, Chinese materia medica develops in a way of a pure natural medicine. It is of great significance that by realizing the natural features, the public nowadays can understand TCM better in its scientific connotations. PMID:17710818

On the origin of giant cells in Hodgkin lymphoma  

PubMed Central

Multinucleated giant tumor cells are frequently observed in tissue sections of lymphoma patients. In Hodgkin lymphoma (HL), these cells are pathognomonic for the disease and named Reed-Sternberg (RS) cells. Despite the well-described disease-promoting functions of RS cells, their development has remained obscure. We addressed this open question by continuous live cell imaging to observe the generation of RS cells. Single-cell tracking of HL cell lines revealed that RS cells develop from mononucleated progenitors that divide and subsequently re-fuse, before they grow and become multinucleated giant cells. Thus, RS cell generation is neither due to cell fusion of unrelated Hodgkin cells nor to endomitosis, as previously suggested. In the majority of cases, re-fusion of daughter cells was preceded by an incomplete cytokinesis, visualized by a persistent microtubule bridge connecting the cells. This surprising finding describes a novel mechanism for the formation of multinuclear giant cells with potential relevance beyond HL.

Complications of treatment of Hodgkin's disease in children  

SciTech Connect

An analysis of complications of therapy requires long-term and frequent followup. Reported here is a review of 179 consecutive children with Hodgkin's disease from Stanford University Medical Center who were seen, treated, and followed over a 20-year period. Complications of treatment are related to the extent of disease and the aggressiveness of therapy. Severe complications from radiotherapy are associated with high-dose, extended-field treatment in preadolescent children. Severe chemotherapy-associated complications include immunosuppression, sterility, and secondary oncogenesis. As cure rates are increasingly optimistic among children with Hodgkin's disease, successful treatment with minimal morbidity remains our greatest challenge. Therapy programs require continual refinement utilizing assessment of short- and long-term side effects of treatment.

Unusual thoracic radiographic findings in children treated for Hodgkin's disease  

SciTech Connect

Mantle irradiation is often part of the treatment for Hodgkin's disease. Localized pneumonitis and fibrosis are well-known sequelae of this treatment. We report nine patients with unusual thoracic radiographic findings following treatment for Hodgkin's disease. All nine had mediastinal widening. Seven of these patients received combined modality therapy in which prednisone was given with their MOPP. In these seven patients, an increase in mediastinal width developed at the same time as the radiographic changes of radiation pneumonitis. Two patients developed bilateral infiltrates extending beyond the field of radiation to the lung periphery. In one of these patients, a spontaneous pneumomediastinum developed. One patient underwent mediastinal biopsy that revealed inflammatory changes similar to those seen in radiation pneumonitis. All patients either responded to steroids or had spontaneous regression of radiographic abnormalities supporting the presumed diagnosis of treatment related changes. Recognition of these unusual sequelae of mantle irradiation will aid in differentiating them from infection or tumor and lead to prompt, appropriate treatment.

Multimodality therapy of favorable prognosis non-Hodgkin's lymphoma  

SciTech Connect

Twenty-seven previously untreated patients with favorable prognosis non-Hodgkin's lymphoma were treated with a combination of total body irradiation followed by cyclophosphamide - vincristine - prednisone (CVP). The dose of total body irradiation was planned to be 150 rad followed by 6 cycles of chemotherapy. The complete response rate was 59%; the complete plus partial response rate, 93%. The 50% disease-free survival was 8 months. The actuarial projected 5 year survival was 60% and the disease-free survival at 5 years was 27%. The program was well tolerated by the majority of patients. It is possible for some patients with favorable non-Hodgkin's lymphomas to achieve prolonged periods of disesase-free survival when treated with combinations of irradiation plus chemotherapy.

Primary non-Hodgkin's lymphoma of the urinary bladder.

Primary non-Hodgkin's lymphoma of the bladder is a rare entity and when found in such an unusual location is often difficult to distinguish from other vesical or extravesical neoplasms. Understanding of the pathobiological characteristics of this malignancy has been hampered not only because of its rarity but also by the previous confusion in its nomenclature. Factors that influence survival most strongly are the stage and the bulk of disease at presentation and the histologic classification of the tumor. We report a case of primary non-Hodgkin's lymphoma of the bladder presenting as a large pelvic mass which dramatically regressed with systemic chemotherapy with simultaneous restoration of the upper dilated urinary tracts. In addition, the incidence, clinical picture, staging procedures, histologic classification and treatment modalities of this disease are reviewed. PMID:1606990

Traditional Chinese drug therapy.  

PubMed

More than 4,000 years old, traditional Chinese medicine continues to be widely practiced in China and in western countries. Traditional Chinese medicine teaches that good health is the result of harmony and balance between five basic elements: earth, water, fire, wood and metal. Also important to health are the two types of energy Yin and Yang, constituting a vital substance that circulates through the body. Drug therapy has been one of the means used in Chinese medicine to keep these elements and the flow of energy in balance. Many of the same herbs used thousands of years ago in China could be the source of new pharmaceuticals in Western medicine. PMID:14747850

Irinotecan in relapsed or refractory non-Hodgkin's lymphoma.  

PubMed

Irinotecan (CPT-11, Camptosar) is a topoisomerase I inhibitor with a broad spectrum of antitumor clinical activity. Various schedules and doses have been studied, and major complications were delayed diarrhea and myelosuppression. We explored the activity of irinotecan in patients with relapsed or refractory non-Hodgkin's lymphoma, using a 3-week schedule of administration. Eligible patients had histologically proven relapse, had received no more than two previous regimens, were > or = 15 years and < or = 75 years old, had normal renal function, neutrophil count > 1,500/microL, platelet count > 100,000/microL, and no human immunodeficiency virus infection or central nervous system involvement. Patients were treated with irinotecan 300 mg/m2 i.v. every 21 days with intensive loperamide management of diarrhea. Responders received up to six treatment cycles. Of 25 patients registered so far, 22 are evaluable for response. The median age was 67 years (range: 25 to 74 years) and 11 were male. The median number of previous regimens was 2 (range: 1 to 4 regimens), and 16 patients had disease that was refractory to their last regimen. Serum lactate dehydrogenase level was high in 75%, and beta2-microglobulin was > 3.0 mg/L in 26% of patients. Responses were seen in 8 of 22 (36%) patients with non-Hodgkin's lymphoma. Response rates were 40% for indolent, 0% for mantle cell, 45% for relapsed aggressive, and 33% for refractory aggressive lymphomas. Grade 3/4 toxicities included myelosuppression, neutropenic fever, and delayed diarrhea. Irinotecan appears active and relatively well tolerated in patients with relapsed aggressive non-Hodgkin's lymphoma. Accrual to this study is continuing for better determination of the response rate in all histologic subtypes of non-Hodgkin's lymphoma. PMID:11497233

Distribution of Chinese names

We present a statistical model for the distribution of Chinese names. Both family names and given names are studied on the same basis. With naive expectation, the distribution of family names can be very different from that of given names. One is affected mostly by genealogy, while the other can be dominated by cultural effects. However, we find that both distributions can be well described by the same model. Various scaling behaviors can be understood as a result of stochastic processes. The exponents of different power-law distributions are controlled by a single parameter. We also comment on the significance of full-name repetition in Chinese population.

[New antitumor drugs for non-Hodgkin's lymphoma].  

PubMed

We summarize in this article the antitumor activity of newly developed drugs against non-Hodgkin's lymphoma. The Taxans (paclitaxel and docetaxel), complex polycyclic organic chemicals isolated from the yew tree, have a broad antitumor spectrum with impressive activity in solid tumors. In the SWOG Phase II study on relapsed non-Hodgkin's lymphomas, paclitaxel (Taxol), showed 30% CR and 14% PR. In the CALGB study on docetaxel, a 14.5% response rate (12.5% for low-grade lymphoma and 16.1% for intermediate-high grade lymphoma) was found. In the Japanese phase II study of docetaxel, the response rate was 29.4% for all patients (14.3% for low-grade lymphoma and 40.0% for intermediate-high grade lymphoma). Rituximab is a chimeric monoclonal antibody directed against the B-cell specific antigen CD20. A phase II trial was conducted with four weekly infusions of 375 mg/m2 in patients with relapsed low-grade or follicular lymphoma. The response rate was 46%. A clinical trial combining Rituximab with 6 cycles of CHOP chemotherapy in newly diagnosed patients has recently been completed. Early evaluation of this experience suggests that this combination resulted in a PR or CR in all patients. New purine nucleoside analogs (fludarabine, cladribine, pentostatin) are active against common and generally incurable low-grade lymphoproliferative disorders. These new drugs combined with other chemotherapeutic reagents are expected to overcome refractory or incurable non-Hodgkin's lymphoma. PMID:9881079

Quantum Logic as Classical Logic  

E-print Network

We propose a semantic representation of the standard quantum logic QL within a classical, normal modal logic, and this via a lattice-embedding of orthomodular lattices into Boolean algebras with one modal operator. Thus our classical logic is a completion of the quantum logic QL. In other words, we refute Birkhoff and von Neumann's classic thesis that the logic (the formal character) of Quantum Mechanics would be non-classical as well as Putnam's thesis that quantum logic (of his kind) would be the correct logic for propositional inference in general. The propositional logic of Quantum Mechanics is modal but classical, and the correct logic for propositional inference need not have an extroverted quantum character. One normal necessity modality suffices to capture the subjectivity of observation in quantum experiments, and this thanks to its failure to distribute over classical disjunction. The key to our result is the translation of quantum negation as classical negation of observability.

Classically isospinning Hopf solitons  

NASA Astrophysics Data System (ADS)

We perform full three-dimensional numerical relaxations of isospinning Hopf solitons with Hopf charge up to 8 in the Skyrme-Faddeev model with mass terms included. We explicitly allow the soliton solution to deform and to break the symmetries of the static configuration. It turns out that the model with its rich spectrum of soliton solutions, often of similar energy, allows for transmutations, formation of new solution types, and the rearrangement of the spectrum of minimal-energy solitons in a given topological sector when isospin is added. We observe that the shape of isospinning Hopf solitons can differ qualitatively from that of the static solution. In particular, the solution type of the lowest energy soliton can change. Our numerical results are of relevance for the quantization of the classical soliton solutions.

Impact of highly effective antiretroviral therapy on the risk for Hodgkin lymphoma among people with human immunodeficiency virus infection  

PubMed Central

Purpose of review To estimate the impact of highly effective antiretroviral therapy (ART) on the incidence and prognosis of Hodgkin lymphoma among people with human immunodeficiency virus infection or AIDS (PWHA). Recent findings Age-adjusted incidence of Hodgkin lymphoma in PWHA is unchanged and is still five-fold to fifteen-fold higher than in the general population. Aging of the PWHA population with ART may account for increasing numbers of Hodgkin lymphoma cases. CD4 cell count has a complex relationship to Hodgkin lymphoma risk in PWHA. Depending on the time of measurement, Hodgkin lymphoma risk is highest with 50–249 CD4cells/µl, and falling CD4 count on ART may be a harbinger of Hodgkin lymphoma onset. HIV load appears irrelevant to Hodgkin lymphoma. For obscure reasons, Hodgkin lymphoma risk may be elevated soon after starting ART, but the risk is probably modestly reduced with 6 or more months on ART. For PWHA who develop Hodgkin lymphoma, ART and ABVD chemotherapy can be administered safely, with one recent study demonstrating equivalent outcomes for HIV-positive and HIV-negative Hodgkin lymphoma patients. Summary Vigilance for Hodgkin lymphoma is needed for immune-deficient PWHA, including those on ART. ART with opportunistic infection prophylaxis enables the delivery of effective chemotherapy for Hodgkin lymphoma, leading to a good prognosis. PMID:22729154

Quantum Computing's Classical Problem, Classical Computing's Quantum Problem  

NASA Astrophysics Data System (ADS)

Tasked with the challenge to build better and better computers, quantum computing and classical computing face the same conundrum: the success of classical computing systems. Small quantum computing systems have been demonstrated, and intermediate-scale systems are on the horizon, capable of calculating numeric results or simulating physical systems far beyond what humans can do by hand. However, to be commercially viable, they must surpass what our wildly successful, highly advanced classical computers can already do. At the same time, those classical computers continue to advance, but those advances are now constrained by thermodynamics, and will soon be limited by the discrete nature of atomic matter and ultimately quantum effects. Technological advances benefit both quantum and classical machinery, altering the competitive landscape. Can we build quantum computing systems that out-compute classical systems capable of some logic gates per month? This article will discuss the interplay in these competing and cooperating technological trends.

Serious pulmonary complications in patients receiving recombinant granulocyte colony-stimulating factor during BACOP chemotherapy for aggressive non-Hodgkin's lymphoma.  

PubMed Central

Four of 12 Chinese patients receiving BACOP, in combination with recombinant human granulocyte colony-stimulating factor, for aggressive non-Hodgkin's lymphoma developed a rapidly progressive pneumonic illness characterised by diffuse pulmonary infiltrates and hypoxaemia. The condition proved fatal in three, and in none could an infective cause be identified. A retrospective analysis revealed only one episode of pneumonia in the previous 24 patients in whom the same BACOP regimen was administered without granulocyte colony-stimulating factor support. Granulocyte colony-stimulating factor, by augmenting white cell production, pulmonary sequestration and margination and production of toxic oxygen species, may exacerbate underlying subclinical bleomycin pulmonary toxicity. Caution should be exercised before using granulocyte-stimulating factors in bleomycin-containing regimens. Images Figure 1 Figure 2 Figure 3 PMID:7524599

Classical and quantum ghosts  

E-print Network

The aim of these notes is to provide a self-contained review of why it is generically a problem when a solution of a theory possesses ghost fields among the perturbation modes. We define what a ghost field is and we show that its presence is associated to a classical instability whenever the ghost field interacts with standard fields. We then show that the instability is more severe at quantum level, and that perturbative ghosts can exist only in low energy effective theories. However, if we don't consider very ad-hoc choices, compatibility with observational constraints implies that low energy effective ghosts can exist only at the price of giving up Lorentz-invariance or locality above the cut-off, in which case the cut-off has to be much lower that the energy scales we currently probe in particle colliders. We also comment on the possible role of extra degrees of freedom which break Lorentz-invariance spontaneously.

Classical dynamics on triangleland  

E-print Network

In Euclidean relational particle mechanics (ERPM) only relative times, relative angles and relative separations are meaningful, while in similarity relational particle mechanics (SRPM) only relative times, relative angles and ratios of relative separations are. These theories are clearly of interest in the absolute or relative motion debate. In this paper, ERPM and SRPM are provided in fully reduced form for 3 particles in 2D, i.e. the classical dynamics on triangleland in 2D with and without scale. Exact solutions to each of these are then found, and simple Newton--Coulomb-like and harmonic oscillator-like SRPM models are studied numerically. The mathematics one arrives at thus overlaps in many ways with that which arises in the absolutist approach. The ERPM gives standard mathematics, while the SRPM has standard small-relative-scale behaviour and an unexpected but in itself standard universal large-relative-scale behaviour. One way in which SRPM is unusual is that it is a model in which a symmetry principle underlies an unexpected departure from standard physical behaviour at sufficiently large relative scales (interpolation between the abovementioned two behaviours). ERPM and SRPM are also theoretically interesting at the quantum level, both on their own merit and as toy models for the development of various approaches to the problems of time and of observables in quantum general relativity.

Classical and quantum effective theories  

NASA Astrophysics Data System (ADS)

A generalization of the action principle of classical mechanics, motivated by the closed time path scheme of quantum field theory, is presented to deal with initial condition problems and dissipative forces. The similarities of the classical and the quantum cases are underlined. In particular, effective interactions that describe classical dissipative forces represent the system-environment entanglement. The relation between the traditional effective theories and their closed time path extension is briefly discussed, and a few qualitative examples are mentioned.

A Classic Beauty  

NASA Technical Reports Server (NTRS)

M51, whose name comes from being the 51st entry in Charles Messier's catalog, is considered to be one of the classic examples of a spiral galaxy. At a distance of about 30 million light-years from Earth, it is also one of the brightest spirals in the night sky. A composite image of M51, also known as the Whirlpool Galaxy, shows the majesty of its structure in a dramatic new way through several of NASA's orbiting observatories. X-ray data from NASA's Chandra X-ray Observatory reveals point-like sources (purple) that are black holes and neutron stars in binary star systems. Chandra also detects a diffuse glow of hot gas that permeates the space between the stars. Optical data from the Hubble Space Telescope (green) and infrared emission from the Spitzer Space Telescope (red) both highlight long lanes in the spiral arms that consist of stars and gas laced with dust. A view of M51 with the Galaxy Evolution Explorer telescope shows hot, young stars that produce lots of ultraviolet energy (blue).

The textbook spiral structure is thought be the result of an interaction M51 is experiencing with its close galactic neighbor, NGC 5195, which is seen just above. Some simulations suggest M51's sharp spiral shape was partially caused when NGC 5195 passed through its main disk about 500 million years ago. This gravitational tug of war may also have triggered an increased level of star formation in M51. The companion galaxy's pull would be inducing extra starbirth by compressing gas, jump-starting the process by which stars form.

Treatment of patients with minimal stage IIIA Hodgkin's disease  

SciTech Connect

Treatment recommendations for patients with upper abdominal Stage IIIA Hodgkin's (III1A) disease have varied widely. The current study reports on a combined institutional retrospective review of 85 patients with surgically staged III1A Hodgkin's disease. Twenty-two patients received combined modality therapy (CMT), 36 patients were treated initially with total nodal irradiation (TNI), and 27 with mantle and para-aortic radiotherapy (MPA). Patients treated with CMT had an actuarial 8-year freedom from relapse (FFR) of 96% as compared to a FFR of 51% in TNI treated patients (p = 0.002), and a FFR of 54% in MPA treated patients (p = 0.004). Of the 11 relapses in MPA treated patients, 7 had a component of their failure in the untreated pelvic or inguinal nodes. The patients treated with CMT had an 8-year actuarial survival of 100% as compared to 79% in TNI treated patients (p = 0.055) and 78% in patients treated with MPA (p = 0.025). Histology and the number of splenic nodules were the most important prognostic variables. Patients with MC/LD histology and greater than or equal to 5 splenic nodules have a high risk of relapse (10/13) when treated with radiation alone (TNI or MPA). We recommend CMT for this group of patients. Patients with NS/LP histology and 1-4 splenic nodules represent a favorable subset of Stage III1A patients. Only 4/21 patients have relapsed and all 21 patients are currently alive without disease regardless of treatment. We currently feel that patients with Stage III1A Hodgkin's disease with NS/LP histology and splenic disease limited to 1-4 nodules are good candidates for MPA as an alternative to TNI or CMT.

Scheduled for sometime in 2003, it will be the first step toward China's highly ambitious plans for space exploration.The China National Space Administration Web site (1) has a detailed description of the country's space policy. Aerospace China, a journal published online by the administration, has information on space development plans and other issues. The history of China's space program is recounted by the online Encyclopedia Astronautica (2). Several influential scientists and their contributions to Chinese rocketry and satellite technology are highlighted. The China Academy of Launch Vehicle Technology (3) sent the first Chinese satellite into space. Its home page showcases eight launch vehicles and offers an extensive technical description of the LM-3C model. The work of various research groups at the Shanghai Astronomical Observatory (4) deals with topics ranging from satellite dynamics to stellar astronomy. Some of the groups have details of their projects and facilities online. Another observatory studies molecular clouds and star formation (5). A large collection of its research papers are provided on its Web site. A news article from Space.com (6) discusses the forthcoming launch of the Shenzhou IV spacecraft, scheduled for later this year. It is generating considerable interest, since it is said to be identical to China's first manned spacecraft, expected to launch in 2003. Another article (7) considers China's rapidly developing space program. With the tremendous effort and lofty goals for moon bases and Mars missions, the author argues that China could eventually rival the US. Many more news stories about the Chinese space program can be found on the Dragon Space Web site (8).

Objectives: To study the dietary behavior and knowledge about dental erosion and self-reported symptoms that can be related to dental erosion among Chinese adults in Hong Kong. Methods: Chinese adults aged 25-45 years were randomly selected from a list of registered telephone numbers generated by computer. A telephone survey was administered to obtain information on demographic characteristics, dietary habits, dental visits, and knowledge of and presence of self-reported symptoms that can be related to dental erosion. Results: A total of 520 participants were interviewed (response rate, 75%; sampling error, ± 4.4%) and their mean age was 37. Most respondents (79%) had ever had caries, and about two thirds (64%) attended dental check-ups at least once a year. Respondents had a mean of 5.4 meals per day and 36 % had at least 6 meals per day. Fruit (89%) and lemon tea/water (41%) were the most commonly consumed acidic food and beverage. When asked if they ever noticed changes in their teeth, most respondents (92%) said they had experienced change that can be related to erosion. However, many (71%) had never heard about dental erosion and 53 % mixed up dental erosion with dental caries. Conclusion: Hong Kong Chinese adults have frequent intake of food and many have experienced symptoms that can be related to dental erosion. Their level of awareness of and knowledge about dental erosion is generally low, despite

Polymorphisms in methylenetetrahydrofolate reductase gene and risk of non-Hodgkin lymphoma in a multi-ethnic population.  

PubMed

An imbalance in folate metabolism can adversely affect DNA synthesis and methylation systems which can lead to susceptibility to non-Hodgkin lymphoma (NHL). Whether single nucleotide polymorphisms (SNPs) and their haplotypes in the methylenetetrahydrofolate reductase (MTHFR) are associated with NHL, remain inconclusive. We investigated the association between MTHFR C677T and A1298C SNPs and NHL risk in a population which is made up of Malay, Chinese and Indian ethnic subgroups. A total of 372 NHL patients and 722 controls were genotyped using the Sequenom MassARRAY platform. Our results of the pooled subjects failed to demonstrate significant association between the MTHFR C677T and A1298C SNPs with NHL and its subtypes. The results were in agreement with the previous meta-analyses. In the Indian ethnic subgroup however, single locus analysis of MTHFR A1298C appears to confer risk to NHL (Odds ratio (OR) 1.91, 95% confidence interval (95% CI) 1.22-3.00, P=0.006). The risk is almost doubled in homozygous carrier of MTHFR 1298CC (OR 4.03, 95% CI 1.56-10.43, P=0.004). Haplotype analysis revealed higher frequency of CC in the Indian NHL patients compared with controls (OR 1.86, 95% CI 1.18-2.93, P=0.007). There is lack of evidence to suggest an association between MTHFR C677T and A1298C with the risk of NHL in the Malays and Chinese. In the Indians however, the MTHFR A1298C confers risk to NHL. This study suggests ethnicity modifies the relationship between polymorphisms in the folate-metabolizing gene and NHL. PMID:24646728

Plasma Biomarkers for Detecting Hodgkin's Lymphoma in HIV Patients  

SciTech Connect

The lifespan of AIDS patients has increased as a result of aggressive antiretroviral therapy, and the incidences of the AIDS-defining cancers, Hodgkin's lymphoma and Kaposi sarcoma, are declining, Still, the increased longevity of AIDS patients is now associated with increased incidence of other cancers, including Hodgkin's lymphoma (HL). In order to determine if we could identify biomarkers for the early detection of HL, we undertook an accurate mass and elution time tag proteomics analysis of individual plasma samples from AIDS patients without HL (n=14) and with HL (n=22). This analysis identified 33 proteins, included C-reactive protein and three serum amyloid proteins, that were statistically (p<0.05) altered by at least 1.5-fold between the two groups. At least three of these proteins have previously been reported to be altered in the blood of HL patients. Ingenuity Pathway Analysis software identified 'inflammatory response' and 'cancer' as the top two, biological functions commonly associated with these proteins. The clear association of these proteins with cancer and inflammation suggests that they are truly associated with HL and that they would be useful in the detection of this disease.

Hepatitis C virus and non-Hodgkin's lymphomas.  

PubMed

The etiology of non-Hodgkin's lymphomas (NHL) remains a controversial matter, but, in the last few years, considerable evidence suggests that aberrations of the immune system and viruses may act as etiologic agents, in at least some cases of NHL. In fact, patients with primary immuno-deficiencies, or those suffering from diseases characterized by autoimmune dysfunction, show an increased risk for the development of NHL. Several viruses have been identified as possible etiologic agents for NHL; one of the best studied is the Epstein-Barr virus, which was detected in cultures of tumor cells from patients with Burkitt's lymphoma. The pathogenetic potential of this virus is illustrated by its association with an increasing number of malignant diseases. In addition, the human T-cell lymphotropic virus family (HTLV), was also recognized as possible etiologic agents for several lymphomas, such as cutaneous T-cell lymphoma and T-cell leukemia-lymphoma syndrome (HTLV-I), and T-cell hairy cell leukemia (HTLV-II). Recently, the presence of hepatitis C virus infection has also been recognized in several hematological malignancies such as mixed cryoglobulinemia, low-grade malignant lymphomas and Waldenström's disease. The possible etiopathogenetic role of this virus in non-Hodgkin's lymphomas is discussed on the basis of molecular, clinical, and epidemiological considerations. PMID:8724528

Pericarditis and myocardial infarctions after Hodgkin's disease therapy  

SciTech Connect

From 1971 to 1984, 499 patients with all stages of Hodgkin's disease received mediastinal irradiation at the Institut Gustave-Roussy by 25 MV photons from a linear accelerator. Thirty-five pericarditis (10-year cumulative incidence rate of 9.5%) and 13 myocardial infarctions (MI) (10-year cumulative incidence rate of 3.9%) were observed. In contrast, no cases were diagnosed in a parallel series of 138 Hodgkin's disease patients treated without mediastinal irradiation during the same period of time (p less than 0.005 for pericarditis, p less than 0.05 for MI). By multivariate analysis, the role of total radiation dose given to the mediastinum and that of fraction size were evaluated, adjusting for age, sex, mediastinal involvement, and type of chemotherapy. The pericarditis risk was significantly increased with total dose greater than or equal to 41 Gy (relative risk (RR) = 3.25, p = 0.006) and with dose per fraction greater than or equal to 3.0 Gy (RR = 2.0, p = 0.06). The myocardial infarction risk was not found to be related to total dose nor to fraction size in this series, possibly because of the small number of events.

How to exploit stress-related immunity against Hodgkin's lymphoma  

PubMed Central

Stress-related immunity can be activated in the course of lymphoproliferative disorders, including Hodgkin’s lymphoma, upon the interaction between killer cell lectin-like receptor subfamily K, member 1 (KLRK1, best known as NKG2D) on effector lymphocytes and NKG2D ligands (NKG2DL), such as MHC class I polypeptide-related sequence A (MICA), MICB and various UL16-binding proteins (ULBPs), on lymphoma cells. However, NKG2DLs can also bind NKG2D upon shedding, thus affecting the recognition of lymphoma cells by the immune system. The proteolytic cleavage of MICA depends on protein disulfide isomerase family A, member 6 (PDIA6, a thiol isomerase best known as ERp5) as well as on the disintegrins and metalloproteinases ADAM metallopeptidase domain 10 (ADAM10) and ADAM17, which also cleave ULPBs. These enzymes can be targeted in novel therapeutic schemes to avoid the escape of malignant cells from stress-evoked immune responses. PMID:24498565

Thresholds and Plateaus in the Hodgkin-Huxley Nerve Equations  

PubMed Central

Phase space methods and an analog computer are used to analyze the Hodgkin-Huxley non-linear differential equations for the squid giant axon membrane. V is the membrane potential, m the Na+ activation, h the Na+ inactivation, and n the K+ activation. V and m change rapidly, relative to h and n. The (V, m) phase plane of a reduced system of equations, with h and n held constant at their resting values, has three singular points: a stable resting point, a threshold saddle point, and a stable excited point. When h and n are allowed to vary, recovery and refractoriness result from the movement with subsequent disappearance of the threshold and excited points. Multiplying the time constant of n by 100 or more, and that of h by one-third, reproduces the experimental plateau action potentials obtained with tetraethylammonium by Tasaki and Hagiwara, including the phenomena of abolition and of refractoriness of the plateau duration. The equations have, transiently, two stable states, as found in the real axon by these authors. Since the theoretical membrane conductance curves differ significantly from the experimental ones, further experimental analysis of ionic currents with tetraethylammonium is needed to decide whether the Hodgkin-Huxley model can be generalized to explain these experiments completely.

Diagnosis and management of Hodgkin's disease in the adult.  

PubMed

Appropriate management of Hodgkin's disease is based on both the stage of disease and the specific anatomic sites of involvement within each stage. As a result of the combination of sequential staging and effective treatment, histopathologic subclassification has become less important. Although not generally appreciated, this is also true for constitutional symptoms. During the past 15 years, differences in survival between early and advanced stages have diminished progressively with refinements both in management of newly diagnosed patients, and in management of relapsing disease. Currently, our five-year survival figure for laparotomy-Staged I and II patients is 95%. The corresponding result for Stages IIIA and IIIB patients is 85%; and 67% of our Stage IV patients, who were treated with mechlorethamine, vincristine, procarbazine, and prednisone (MOPP) are projected to be surviving at five years. With the anticipation of a high probability for cure, quality of life including the possibility for parenthood has become increasingly important. In the past, the trend has been to increase treatment for patients with poor prognostic factors. However, very little attention has been paid to the possibility of administering less treatment for very precisely staged patients with good prognostic factors. In this review, management is discussed by stage. Emphasis is placed on the indications for less treatment as well as for more intensive therapy in adult patients with Hodgkin's disease.

UV-completion by classicalization  

NASA Astrophysics Data System (ADS)

We suggest a novel approach to UV-completion of a class of non-renormalizable theories, according to which the high-energy scattering amplitudes get unitarized by production of extended classical objects ( classicalons), playing a role analogous to black holes, in the case of non-gravitational theories. The key property of classicalization is the existence of a classicalizer field that couples to energy-momentum sources. Such localized sources are excited in high-energy scattering processes and lead to the formation of classicalons. Two kinds of natural classicalizers are Nambu-Gold stone bosons (or, equivalently, longitudinal polarizations of massive gauge fields) and scalars coupled to energy-momentum type sources. Classicalization has interesting phenomenological applications for the UVcompletion of the Standard Model both with or without the Higgs. In the Higgless Standard Model the high-energy scattering amplitudes of longitudinal W -bosons self-unitarize via classicalization, without the help of any new weakly-coupled physics. Alternatively, in the presence of a Higgs boson, classicalization could explain the stabilization of the hierarchy. In both scenarios the high-energy scatterings are dominated by the formation of classicalons, which subsequently decay into many particle states. The experimental signatures at the LHC are quite distinctive, with sharp differences in the two cases.

Classical Correlation in Quantum Dialogue  

E-print Network

Classical communications are used in the post-processing procedure of quantum key distribution. Since the security of quantum key distribution is based on the principles of quantum mechanics, intuitively the secret key can only be derived from the quantum states. We find that classical communications are incorrectly used in the so-called quantum dialogue type protocols. In these protocols, public communications are used to transmit secret messages. Our calculations show that half of Alice's and Bob's secret message is leaked through classical channel. By applying Holevo bound, we can see that the quantum efficiency claimed in the quantum dialogue type of protocols is not achievable.

On quantum vs. classical probability  

E-print Network

Quantum theory shares with classical probability theory many important properties. I show that this common core regards at least the following six areas, and I provide details on each of these: the logic of propositions, symmetry, probabilities, composition of systems, state preparation and reductionism. The essential distinction between classical and quantum theory, on the other hand, is shown to be joint decidability versus smoothness; for the latter in particular I supply ample explanation and motivation. Finally, I argue that beyond quantum theory there are no other generalisations of classical probability theory that are relevant to physics.

We analyze numerically the dynamical generation of quantum entanglement in a system of two interacting particles, started in a coherent separable state, for decreasing values of ?. As ??0 the entanglement entropy, computed at any finite time, converges to a finite nonzero value. The limit law that rules the time dependence of entropy is well reproduced by purely classical computations. Its general features can be explained by simple classical arguments, which expose the different ways entanglement is generated in systems that are classically chaotic or regular. PMID:22587162

Quality of Radiotherapy Reporting in Randomized Controlled Trials of Hodgkin's Lymphoma and Non-Hodgkin's Lymphoma: A Systematic Review  

SciTech Connect

Purpose: Standards for the reporting of radiotherapy details in randomized controlled trials (RCTs) are lacking. Although radiotherapy (RT) is an important component of curative therapy for Hodgkin's lymphoma (HL) and non-Hodgkin's lymphoma (NHL), we postulated that RT reporting may be inadequate in Phase III HL and NHL trials. Methods and Materials: We searched PubMed and the Cochrane registry for reports of RCTs involving RT and either HL or NHL published between 1998 and 2007. We screened 133 titles and abstracts to identify relevant studies. We included a total of 61 reports. We assessed these reports for the presence of six quality measures: target volume, radiation dose, fractionation, radiation prescription, quality assurance (QA) process use, and adherence to QA (i.e., reporting of major or minor deviations). Results: Of 61 reports, 23 (38%) described the target volume. Of the 42 reports involving involved-field RT alone, only 8 (19%) adequately described the target volume. The radiation dose and fractionation was described in most reports (54 reports [89%] and 39 reports [64%], respectively). Thirteen reports specified the RT prescription point (21%). Only 12 reports (20%) described using a RT QA process, and 7 reports (11%) described adherence to the QA process. Conclusion: Reporting of RT in HL and NHL RCTs is deficient. Because the interpretation, replication, and application of RCT results depend on adequate description and QA of therapeutic interventions, consensus standards for RT reporting should be developed and integrated into the peer-review process.

Classical theory of radiating strings  

NASA Technical Reports Server (NTRS)

The divergent part of the self force of a radiating string coupled to gravity, an antisymmetric tensor and a dilaton in four dimensions are calculated to first order in classical perturbation theory. While this divergence can be absorbed into a renormalization of the string tension, demanding that both it and the divergence in the energy momentum tensor vanish forces the string to have the couplings of compactified N = 1 D = 10 supergravity. In effect, supersymmetry cures the classical infinities.

Targeting the IL-4/IL-13 signaling pathway sensitizes Hodgkin lymphoma cells to chemotherapeutic drugs.  

PubMed

Hodgkin/Reed-Sternberg lymphoma (HL) is a clonal B-cell-related malignancy. Although many patients with HL can be cured by the current regimen of high-dose multi-agent chemotherapy, the treatment causes high risks of later pathologies including secondary malignancies. This fact highlights the demand to develop rational treatment for HL. Survival and growth of HL cells are largely dependent on their microenvironment. In this study, using the HL cell lines L1236 and KM-H2 as model systems, we investigated the role of IL-4/IL-13 signaling in regulation of drug sensitivity and resistance in HL. We show that specific blocking of IL-4 and IL-13-mediated STAT6 activation by either an IL-4-binding fusion protein APG598 or an IL-4R antagonist APG201 (R121D/Y124D) renders HL cells more prone to apoptotic killing by chemotherapeutic drugs such as Mitomycin C, 5-Fluorouracil, Etopside, Doxorubicin and Paclitaxel. This effect is due to inhibition of STAT6-mediated elevation of expression of the anti-apoptotic Bcl-2 family protein Bcl-xL. Employing ChIP analysis in combination with APG201 or STAT6-specific siRNA we identified a defined STAT6-binding site in the Bcl-xL promoter region from -1967 to -1957 of the transcription start site. Our data demonstrate that the IL-4/IL-13-STAT6-Bcl-xL axis may be an important target for HL treatment. This study also suggests that combination of classical chemotherapeutic drugs with the IL-4/IL-13 antagonists may enhance efficacy and reduce risks of toxicity from high dose of drugs in HL treatment.

This study aimed to compare perinatal outcomes in native Chinese, foreign-born and US-born Chinese-American women by analysing a cohort of 950,624 singleton pregnancies in south-east China and 293,849 singleton births from the US live and stillbirth certificates from 1995 to 2004. Only births at 28 weeks or later were included. Compared with US-born Chinese-American women, native Chinese and foreign-born Chinese-American women had substantially lower risks of having a small-for-gestational age (SGA) infant (adjusted relative risk [aRR] ranging from 0.46 to 0.66) or preterm birth (aRR ranging from 0.53 to 0.82). While having a White or Black father had a reduced risk of SGA (aRR=0.45 and 0.62, respectively), it has an increased risk for preterm birth (aRR=1.13 and 1.57, respectively). Infants with Chinese father and foreign-born mother were heavier than those with Chinese father and US-born mothers. All findings were statistically significant. Our findings demonstrated the protective role of foreign-born status on low birthweight and preterm delivery. The paternal contribution to fetal size is substantial. PMID:21470259

Three-dimensional Telomere Signatures of Hodgkin- and Reed-Sternberg Cells at Diagnosis Identify Patients with Poor Response to Conventional Chemotherapy1  

PubMed Central

In classic Hodgkin lymphoma (HL) the malignant mononuclear Hodgkin (H) and multinuclear Reed-Sternberg (RS) cells are characterized by a distinct three-dimensional nuclear telomere organization with shortening of the telomere length and the formation of telomeric aggregates. We asked if the severity of these telomere changes correlates with the clinical behavior of the disease. We retrospectively evaluated three-dimensional telomere organization by quantitative fluorescent in situ hybridization (Q-FISH) of diagnostic biopsies from 16 patients who were good responders and compared them with 16 diagnostic biopsies of 10 patients with refractory or relapsing HL (eight initial biopsies, four confirming progressions, and four confirming relapses). The H cells from patients with refractory/relapsing disease contained a significantly higher percentage of very small telomeres (P = .027) and telomere aggregates (P = .032) compared with H cells of patients entering rapid remission. These differences were even more significant (P = .002 and P = .013, respectively) when comparing the eight initial diagnostic biopsies of refractory/relapsing HL with diagnostic biopsies of eight patients with ongoing long-lasting remission (mean of 47 months). This specific three-dimensional telomere Q-FISH signature identifies these highly aggressive mononuclear H cells at the first diagnostic biopsy and thus may offer a new molecular marker to optimize initial treatment.

By combining Chinese expertise in medicinal compounds and cell culturing with Western technical and marketing skills, the institute hopes to develop products that could be licensed to Hong Kong or Western films. The institute is also developing experimental cell lines and making genetically engineered versions of promising compounds, taking advantage of the cell-culturing and cloning skills that are highly developed on the mainland. The Shanghai contingent is already involved in one of the institute's projects, an effort to transfer human genes into mouse fibroblasts to create cell lines for research on the molecular mechanisms of learning and memory. Other Chinese researchers are taking part in HKIB's joint venture with Syntex, which was signed last April. The mainland researchers extract candidate medicinal compounds from plants and microorganisms. In Hong Kong, the compounds are tested for their effects on neurotransmitter receptors, while Syntex scientists in Palo Alto study how the same compounds affect enzyme activity and whole cells.

Hodgkin's disease with leptomeningeal involvement. Report of a case with long survival  

SciTech Connect

A 30-year-old white man with Stage IV B Hodgkin's disease, mixed cellularity type, developed leptomeningeal involvement shortly after relapsing on nitrogen mustard, Oncovin (vincristine), procarbazine, and prednisone (MOPP), and while receiving Adriamycin (doxorubicin), bleomycin, Velban (vinblastine), and dacarbazine (ABVD). Whole brain irradiation and intrathecal methotrexate were successfully incorporated into his treatment program. The patient has now been in complete remission for more than 40 months. A review of this rare complication of Hodgkin's disease is presented.

Hodgkin Disease--An Ever-Evolving Therapy  

PubMed Central

Therapy of Hodgkin lymphoma (HL) is a rapidly changing field due to plenty of currently emerging data. Treatment approaches are currently based on tailoring of therapy in order to achieve a maximal response with minimal toxicity. Since the median age of HL patients is 33 years and their prospective life expectancy of another half a century, a major emphasis needs to be put on dramatic reduction of later toxicity. The assessment of the treatment effect should be based not only on progression-free survival, but should include evaluation of cardiac toxicity, secondary neoplasms, and fertility in the long-term follow-up. The ancient principle “first do no harm” should be central in HL therapy. Completion of ongoing and currently initiated trials could elucidate multiple issues related to the management of HL patients. PMID:25386345

Coronary heart disease mortality after irradiation for Hodgkin's disease  

SciTech Connect

The authors conducted a study designed to evaluate the hypothesis that irradiation to the heart in the treatment for Hodgkin's disease (HD) is associated with increased coronary heart disease (CHD) mortality. This report describes 957 patients diagnosed with HD in 1942-75 and analyzes follow-up findings through December 1977. Twenty-five coronary heart disease deaths have been observed, and 4258.2 person-years of experience at risk have been accrued. The relative death rate (RDR), defined as the CHD mortality for heart-irradiated subjects divided by the mortality for nonirradiated subjects, was estimated. After adjustment for the effect of interval of observation, age, stage, and class, the RDR estimate is 1.5 but does not differ significantly from unit (95% confidence limits: 0.59, 3.7).

[Molecular target therapy for non-Hodgkin lymphoma].  

PubMed

Non-Hodgkin lymphomas(NHL) encompass various types of lymphoid neoplasms with different biological behavior. Comprehensive genomic analysis identifies novel mutation and signaling pathways in various tumors, which leads to rational approaches in cancer therapy. Molecular target therapy is a new approach focusing on specific protein or signaling pathways. Molecules of signaling pathways of B-cell receptor, PI3K/Akt/mTOR and NF-kappaB are rational target, and many new drugs targeting the pathways are developing in various subtypes of lymphoma. Monoclonal and novel conjugated antibodies for cell surface proteins, epigenetic modulators and immunomodulatory agents also show promising clinical activities. This review will focus on the new molecular target drugs and their activity in NHL. PMID:25016812

Treatment selection for stage IIIA Hodgkin's disease patients  

SciTech Connect

Two treatment policies for the therapy of patients with Stage IIIA Hodgkin's disease are compared. From 1969-1976, 49 newly diagnosed and pathologically staged IIIA patients received total nodal irradiation (TNI) alone (no liver irradiation). Although actuarial survival was 80% at 5 years and 68% at 10 years, actuarial freedom from relapse was only 38% at 5 years. Accordingly, a new treatment policy was instituted in 1976. Patients with either CS IIIA disease, multiple splenic nodules, IIIA with a large mediastinal mass or III/sub 2/, received combined modality therapy (combination chemotherapy and irradiation). All others received TNI. Thirty-six patients have been treated under the new program. The actuarial survival is 90% at 5 years and the relapse-free survival is 87%, suggesting the superiority of this approach. Complications from the treatments are discussed.

Non-Hodgkin's lymphomas, version 2.2014.  

PubMed

Non-Hodgkin's lymphomas (NHLs) are a heterogeneous group of lymphoproliferative disorders originating in B lymphocytes, T lymphocytes, or natural killer cells. Follicular lymphoma (FL) is the most common subtype of indolent NHL, accounting for approximately 22% of all newly diagnosed cases of NHL. The incorporation of rituximab to chemotherapy regimens has become a widely accepted standard of care for first-line therapy for patients with FL. Maintenance and consolidation therapy with rituximab and radioimmunotherapy have also been associated with improved progression-free survival in patients experiencing response to first-line therapy. Despite therapeutic advances that have improved outcomes, FL is generally considered a chronic disease characterized by multiple recurrences with current therapies. This manuscript discusses the recommendations outlined in the NCCN Guidelines for the diagnosis and management of patients with FL. PMID:24925202

Non-Hodgkin's lymphomas (NHL) are a heterogeneous group of lymphoproliferative disorders originating in B lymphocytes, T lymphocytes, or natural killer cells. Mantle cell lymphoma (MCL) accounts for approximately 6% of all newly diagnosed NHL cases. Radiation therapy with or without systemic therapy is a reasonable approach for the few patients who present with early-stage disease. Rituximab-based chemoimmunotherapy followed by high-dose therapy and autologous stem cell rescue (HDT/ASCR) is recommended for patients presenting with advanced-stage disease. Induction therapy followed by rituximab maintenance may provide extended disease control for those who are not candidates for HDT/ASCR. Ibrutinib, a Bruton tyrosine kinase inhibitor, was recently approved for the treatment of relapsed or refractory disease. This manuscript discusses the recommendations outlined in the NCCN Guidelines for NHL regarding the diagnosis and management of patients with MCL. PMID:25190696

Advanced Hodgkin Lymphoma: a New Era of Therapy  

PubMed Central

Therapy of advanced Hodgkin lymphoma (HL) is a rapidly changing field due to a lot of currently emerging data. Treatment approaches are presently based on either the Kairos principle of giving aggressive therapy upfront and considering de-escalation of therapy if the interim PET/CT is negative or the Chronos principle of starting with ABVD followed by escalation of therapy for patients with positive interim PET/CT. The International Prognostic Score (IPS) is still valid for decision-making regarding the type of initial therapy, since patients with a high score do have an inferior progression free survival (PFS) with ABVD compared to those with a low score. Escalated BEACOPP administered upfront improves PFS; however, increase in the overall survival (OS) has not been confirmed yet, and this therapy is accompanied by elevated toxicity and fertility impairment. Completion of ongoing and currently initiated trials could elucidate multiple issues related to the management of HL patients.

Hodgkin's Lymphoma in Older Patients: an Orphan Disease?  

PubMed Central

Hodgkin Lymphoma HL can be cured in the large majority of younger patients, but prognosis for older patients, especially those with advanced-stage disease, has not improved substantially. The percentage of HL patients aged over 60 ranges between 15% and 35%. A minority of them is enrolled into clinical trials. HL in the elderly have some specificities: more frequent male sex, B-symptoms, advanced stage, sub diaphragmatic presentation, higher percentage of mixed cellularity, up to 50% of advanced cases associated to EBV. Very old age (>70) and comorbidities are factor of further worsening prognosis. Like in younger patients, ABVD is the most used protocol, but treatment outcome remains much inferior with more frequent, severe and sometimes specific toxicities. Few prospective studies with specific protocols are available. The main data have been published by the Italian Lymphoma Group with the VEPEMB schedule and the German Hodgkin Study Group with the PVAG regimen. Recently, the Scotland and Newcastle Lymphoma Study Group published the SHIELD program associating a prospective phase 2 trial with VEPEMB and a prospective registration of others patients. Patients over 60y with early-stage disease received three cycles plus radiotherapy and had 81% of 3-year overall survival (OS). Those with advanced-stage disease received six cycles, with 3-year OS of 66%. The role of geriatric and comorbidity assessment in the treatment’s choice for HL in the elderly is a major challenge. The combination of loss of activities of daily living combined with the age stratification more or less 70y has been shown as a simple and effective survival model. Hopes come from promising new agents like brentuximab-vedotin (BV) a novel antibody-drug conjugate. The use of TEP to adapt the combination of chemotherapy and radiotherapy according to the metabolic response could also be way for prospective studies. PMID:25045458

Percolation in the classical blockmodel  

NASA Astrophysics Data System (ADS)

Classical blockmodel is known as the simplest among models of networks with community structure. The model can be also seen as an extremely simply example of interconnected networks. For this reason, it is surprising that the percolation transition in the classical blockmodel has not been examined so far, although the phenomenon has been studied in a variety of much more complicated models of interconnected and multiplex networks. In this paper we derive the self-consistent equation for the size the global percolation cluster in the classical blockmodel. We also find the condition for percolation threshold which characterizes the emergence of the giant component. We show that the discussed percolation phenomenon may cause unexpected problems in a simple optimization process of the multilevel network construction. Numerical simulations confirm the correctness of our theoretical derivations.

Coupling ``Classical'' and Quantum Variables  

E-print Network

Experimentally, certain degrees of freedom may appear classical because their quantum fluctuations are smaller than the experimental error associated with measuring them. An approximation to a fully quantum theory is described in which the self-interference of such ``quasiclassical'' variables is neglected so that they behave classically when not coupled to other quantum variables. Coupling to quantum variables can lead to evolution in which quasiclassical variables do not have definite values, but values which are correlated to the state of the quantum variables. A mathematical description implementing this backreaction of the quantum variables on the quasiclassical variables is critically discussed.

Chinese culture and fertility decline.  

PubMed

Coale has suggested that cultural factors exert a significant influence on fertility reduction; countries in the "Chinese cultural circle" would be the first to show fertility decline. In China, the view was that traditional Chinese culture contributed to increased population. This paper examines the nature of the relationship between Chinese culture and fertility. Attention was directed to a comparison of fertility rates of developing countries with strong Chinese cultural influence and of fertility within different regions of China. Discussion was followed by an explanation of the theoretical impact of Chinese culture on fertility and direct and indirect beliefs and practices that might either enhance or hinder fertility decline. Emigration to neighboring countries occurred after the Qing dynasty. Fertility after the 1950s declined markedly in Japan, Singapore, Hong Kong, South Korea, Taiwan, and mainland China: all countries within the Chinese cultural circle. Other countries within the Chinese circle which have higher fertility, yet lower fertility than other non-Chinese cultural countries, are Malaysia, Thailand, and Indonesia. Within China, regions with similar fertility patterns are identified as coastal regions, central plains, and mountainous and plateau regions. The Han ethnic group has lower fertility than that of ethnic minorities; regions with large Han populations have lower fertility. Overseas Chinese in East Asian countries also tend to have lower fertility than their host populations. Chinese culture consisted of the assimilation of other cultures over 5000 years. Fertility decline was dependent on the population's desire to limit reproduction, favorable social mechanisms, and availability of contraception: all factors related to economic development. Chinese culture affects fertility reduction by affecting reproductive views and social mechanisms directly, and indirectly through economics. Confucianism emphasizes collectivism, self-reliance, education and cultivation of moral character, and atheism. Confucian beliefs that interfere with fertility decline are the advocacy of self-sufficient livelihood, the emphasis on family and lineage, autocracy, patriarchy and feudal rule, the 5 constant virtues, contempt for labor and working people, science and technology, and a closed-door policy. Socialism hindered fertility decline by promoting population growth as a symbol of the superiority of socialism and by lack of recognition of population or environmental problems in socialist countries. The goal is to accept Westernization, reduce obstacles, develop economically, and use cultural influence positive to fertility decline. PMID:12317926

Classical simulation of entangled states  

NASA Astrophysics Data System (ADS)

Characterization of nonclassicality or quantumness of a state is fundamental to foundations of quantum mechanics and quantum information. At the heart of the problem is the question whether there exist classical systems—howsoever complicated—that can mimic a given quantum state. Whilst this has been traditionally addressed through the violation of Bell inequality or nonseparability, we show that it is possible to go beyond them, by introducing the concept of classical simulation. Focusing on the two-qubit case, we show that, while for pure states, classical simulability is equivalent to existence of a local hidden variable (LHV) model, the conditions for simulability can be weaker for mixed states, demanding what we call only a generalized LHV description. Consequently, quantum states which defy a classical simulation—which we call exceptional—may require conditions which are more stringent than violation of Bell inequalities. We illustrate these features with a number of representative examples and discuss the underlying reasons, by employing fairly simple arguments.

Non-perturbative classical theory  

E-print Network

Abstract. A theory for the scattering of polarized radiation with partial frequency redistribution and coherence effects in the presence of magnetic fields of arbitrary strength and direction is developed within a classical framework. The time-dependent equation for a classical oscillator is solved. While the oscillator is being excited, it is also damped by emission of radiation and subject to phase-destroying collisions. Fourier transformation of the emitted wave train with phase-scrambling collisions leads to the partial-redistribution expressions for the relation between the polarization and frequencies of the incident and scattered radiation. While previous treatments of partial redistribution have been based on quantum perburbation theory, the classical theory has the advantage of being fully non-perturbative. It is therefore conceptually more transparent and leads itself to direct physical interpretation. The classical and quantum theories give identical results for a J =0 ? 1 ? 0 transition. Key words: atomic processes – line: formation – scattering – polarization – magnetic fields – radiative transfer 1.

Measurement-Based Classical Computation  

NASA Astrophysics Data System (ADS)

Measurement-based quantum computation (MBQC) is a model of quantum computation, in which computation proceeds via adaptive single qubit measurements on a multiqubit quantum state. It is computationally equivalent to the circuit model. Unlike the circuit model, however, its classical analog is little studied. Here we present a classical analog of MBQC whose computational complexity presents a rich structure. To do so, we identify uniform families of quantum computations [refining the circuits introduced by Bremner et al. Proc. R. Soc. A 467, 459 (2010)] whose output is likely hard to exactly simulate (sample) classically. We demonstrate that these circuit families can be efficiently implemented in the MBQC model without adaptive measurement and, thus, can be achieved in a classical analog of MBQC whose resource state is a probability distribution which has been created quantum mechanically. Such states (by definition) violate no Bell inequality, but, if widely held beliefs about computational complexity are true, they, nevertheless, exhibit nonclassicality when used as a computational resource—an imprint of their quantum origin.

Differentiation of classical music requires little learning but rhythm.  

PubMed

Detecting distinctions between the styles of classical music (e.g. Baroque and Romantic) is often viewed as the privilege of musicians. However, this elite perspective underestimates the abilities of non-musicians. We report that Western musicians and non-musicians, and non-Westerners (i.e. Chinese participants) rated pairs of excerpts presented auditorily as more similar as their compositional styles were closer in history. Moreover, the styles were considered by all participants as more different when presented in historical order, the older style preceding the more recent style (e.g. Baroque followed by Romantic), than the reverse (e.g. Romantic followed by Baroque). This historical distance effect appears related to rhythm (or temporal variability). PMID:15925570

Conceptually, this strategy seeks to increase efficacy and minimize toxicity through the appropriate selection of patients for either therapy escalation (high-risk, PET positive) or de-escalation (low-risk, PET negative). Preliminary evidence with tailoring both chemotherapy (drug selection, number of cycles, and dose) and radiotherapy (omission or inclusion) is varied; however, numerous clinical trials seeking to validate this approach are ongoing. This paper summarizes the available evidence and active protocols involving PET response-adapted therapy for adult (early and advanced stages) Hodgkin’s lymphoma. 1.

Leukemia and non-Hodgkin's lymphoma and residential proximity to industrial plants  

SciTech Connect

The risks of developing leukemia and non-Hodgkin's lymphoma from living near industrial facilities were evaluated among men from Iowa and Minnesota in a population-based, case-control study. We found a statistically significant increase in the risk of developing non-Hodgkin's lymphoma (RR = 1.4) and a slight, nonsignificant excess for leukemia (RR = 1.2) among individuals who lived .8-3.2 km (1/2-2 miles) from a factory. Risks were greater for certain histologic types: follicular lymphoma (RR = 1.5), acute lymphocytic leukemia (RR = 5.4), and acute myelocytic leukemia (RR = 2.2). For non-Hodgkin's lymphoma (but not for leukemia), the relative risks for those living within .8 km (1/2 mile) of a factory were similar or slightly larger than for those living .8-3.2 km (1/2-2 miles) from a factory. Risks did not increase with duration of residence near a factory. The elevated risks of non-Hodgkin's lymphoma were particularly associated with residing near stone, clay, or glass industry facilities. The risk of developing leukemia was greater among persons who resided near chemical and petroleum plants. These preliminary findings raise the possibility that general environmental exposure associated with certain industrial activities may elevate the risk of developing leukemia and non-Hodgkin's lymphoma. Evaluation of data on proximity to industrial plants from studies in other geographic locations is needed to determine whether our results represent a meaningful association.

The Classical Stellar Atmosphere Problem  

E-print Network

We introduce the classical stellar atmosphere problem and describe in detail its numerical solution. The problem consists of the solution of the radiation transfer equations under the constraints of hydrostatic, radiative and statistical equilibrium (non-LTE). We outline the basic idea of the Accelerated Lambda Iteration (ALI) technique and statistical methods which finally allow the construction of non-LTE model atmospheres considering the influence of millions of metal absorption lines. Some applications of the new models are presented.

Quantum Mechanics as Classical Physics  

E-print Network

Here I explore a novel no-collapse interpretation of quantum mechanics which combines aspects of two familiar and well-developed alternatives, Bohmian mechanics and the many-worlds interpretation. Despite reproducing the empirical predictions of quantum mechanics, the theory looks surprisingly classical. All there is at the fundamental level are particles interacting via Newtonian forces. There is no wave function. However, there are many worlds.

Schroedinger equation and classical physics  

E-print Network

Any time-dependent solution of Schr\\"{o}dinger equation may be always correlated to a solution of Hamilton equations or to a statistical combination of their solutions; only the set of corresponding solutions is somewhat smaller (due to existence of quantization). There is not any reason to the physical interpretation according to Copenhagen alternative as Bell's inequalities are valid in the classical physics only (and not in any alternative based on Schr\\"{o}dinger equation). The advantage of Schr\\"{o}dinger equation consists then in that it enables to represent directly the time evolution of a statistical distribution of classical initial states (which is usual in collision experiments). The Schr\\"{o}dinger equation (without assumptions added by Bohr) may then represent the common physical theory for microscopic as well as macroscopic physical systems. However, together with the last possibility the solutions of Schr\\"{o}dinger equation may be helpful also in analyzing the influence of other statistically distributed properties (e.g., spin orientations or space structures) of individual matter objects forming a corresponding physical system, which goes in principle beyond the classical physics. In any case, the contemporary quantum theory represents the phenomenological approximative description of some matter characteristics only, without providing any insight into quantum mechanism emergence. In such a case it is necessary to take into account more detailed properties at least of some involved objects.

Quantum to Classical Randomness Extractors  

E-print Network

The goal of randomness extraction is to distill (almost) perfect randomness from a weak source of randomness. When the source yields a classical string X, many extractor constructions are known. Yet, when considering a physical randomness source, X is itself ultimately the result of a measurement on an underlying quantum system. When characterizing the power of a source to supply randomness it is hence a natural question to ask, how much classical randomness we can extract from a quantum system. To tackle this question we here take on the study of quantum-to-classical randomness extractors (QC-extractors). We provide constructions of QC-extractors based on measurements in a full set of mutually unbiased bases (MUBs), and certain single qubit measurements. As the first application, we show that any QC-extractor gives rise to entropic uncertainty relations with respect to quantum side information. Such relations were previously only known for two measurements. As the second application, we resolve the central open question in the noisy-storage model [Wehner et al., PRL 100, 220502 (2008)] by linking security to the quantum capacity of the adversary's storage device.

Iconicity of simple Chinese characters.  

PubMed

The iconicity of a Chinese character, or the degree to which it looks like the concept that it represents, has been suggested as affecting the learning and processing of the character. However, previous studies have not provided good empirical information on the iconicity of specific characters. To fill this gap, 40 U.S. adults with no knowledge of Chinese were given an English word or short phrase together with two Chinese characters and were asked which character matched the meaning of the English word. The right and wrong answers had the same number of strokes, and different wrong answers were used for different participants. We examined all 213 simple-structure Chinese characters that occur in textbooks for elementary school children. The overall percentage of correct responses was 53.6%, slightly but significantly higher than would be expected by chance. Using a false discovery rate procedure, we found that 15 of the 213 characters were guessed at a level higher than chance. The proportion of correct responses to each character, which can be taken as an indicator of its degree of iconicity, should be useful to researchers studying Chinese character reading and writing. The full database, showing the proportion of correct guesses and other psycholinguistic variables for each character, can be downloaded from http://brm.psychonomic-journals.org/content/supplemental .

The current study focused on a group of Chinese-American professionals working in a scientific environment in the San Francisco Bay area. One of the goals of the present study is to determine to what extent do the Chinese cultural values impact job performance, interpersonal relationships and perception of job satisfaction. This was carried out by identifying the important motivational factors and optimal working conditions which provided career satisfaction for the Chinese-American professionals. Comparisons were made between the US born and foreign-born respondents to determine differences, if any, in their perceptions relative to career satisfaction due to varying acculturation levels. In addition, this study identified barriers to career advancement and compared these barriers with the results of another survey on the Chinese-American professionals working in government, industry and private sector in the Bay area. A structured survey questionnaire was designed by the investigator and sent to 167 Chinese-American professionals, composed of both US-born and foreign-born. 41 refs., 12 figs., 8 tabs.

Acoustics of Chinese traditional theatres  

NASA Astrophysics Data System (ADS)

Chinese traditional theatre is unique in the world as an architectural form. The Chinese opera evolved into maturity as early as the Song and Yuan Dynasties, 11th-14th centuries, and Chinese theatrical buildings developed accordingly. As the Chinese opera plays on the principle of imaginary actions, no realistic stage settings are required. But Chinese audiences have placed great demands on vocal performance since ancient times. Pavilion stages that are small in area, open on three sides, and thrusting into the audience area are commonly found in traditional theatres, both the courtyard type and auditorium type. The pavilion stage is backed with a wall and a low ceiling (flat or domed). The stage functions as a reflecting shell, which enhances the sound to the audience and provides self-support to the singer. Numerous theatres of this kind exist and function in good condition to the present time. Acoustical measurements show that the sound strength and clarity in audience areas is satisfactory in moderate size courtyard traditional theatres. [Work supported by NSF.

Developing classification indices for Chinese pulse diagnosis  

E-print Network

Aim: To develop classification criteria for Chinese pulse diagnosis and to objectify the ancient diagnostic technique. Methods: Chinese pulse curves are treated as wave signals. Multidimensional variable analysis is performed to provide the best curve fit between the recorded Chinese pulse waveforms and the collective Gamma density functions. Results: Chinese pulses can be recognized quantitatively by the newly-developed four classification indices, that is, the wave length, the relative phase difference, the rate parameter, and the peak ratio. The new quantitative classification not only reduces the dependency of pulse diagnosis on Chinese physician's experience, but also is able to interpret pathological wrist-pulse waveforms more precisely. Conclusions: Traditionally, Chinese physicians use fingertips to feel the wrist-pulses of patients in order to determine their health conditions. The qualitative theory of the Chinese pulse diagnosis is based on the experience of Chinese physicians for thousands of year...

Spontaneous spiking in an autaptic Hodgkin-Huxley setup.  

PubMed

The effect of intrinsic channel noise is investigated for the dynamic response of a neuronal cell with a delayed feedback loop. The loop is based on the so-called autapse phenomenon in which dendrites establish connections not only to neighboring cells but also to its own axon. The biophysical modeling is achieved in terms of a stochastic Hodgkin-Huxley model containing such a built in delayed feedback. The fluctuations stem from intrinsic channel noise, being caused by the stochastic nature of the gating dynamics of ion channels. The influence of the delayed stimulus is systematically analyzed with respect to the coupling parameter and the delay time in terms of the interspike interval histograms and the average interspike interval. The delayed feedback manifests itself in the occurrence of bursting and a rich multimodal interspike interval distribution, exhibiting a delay-induced reduction in the spontaneous spiking activity at characteristic frequencies. Moreover, a specific frequency-locking mechanism is detected for the mean interspike interval. PMID:21230690

Non-Hodgkin lymphoma in common variable immunodeficiency.  

PubMed

The association between cancer and immunodeficiency is well established. In common variable immunodeficiency (CVI), a primary immunodeficiency disease characterized by low serum immunoglobulins and poor antibody production, we previously reported a total of 13 cancers in 11 individuals arising in continuously observed group of patients. Of the 13, 7 were NHL and 1 was a myeloma which progressed to lymphoma. We report here the histologic, immunologic, cytogenetic, and clinical features of these 8 NHL along with 3 new lymphomas which have appeared in this group (now 117 patients). From our studies, the lymphomas which have arisen in CVI share certain features with the lymphomas which appear in the childhood immunodeficient syndromes. Wiskott Aldrich Syndrome, Ataxia Telangiectasia, or severe combined immunodeficiency: they are similar in overall frequency (13%), are often B-cell in origin, and extranodal in location. However, unlike the lymphomas of the immunodeficient child, lymphomas in CVI may be more differentiated and secrete immunoglobulin. For CVI patients with stage I or II disease, as for non-Hodgkin lymphomas in general, the prognosis is good. In our group, NHL in CVI have appeared most often in females of the 5th to 7th decade and not in childhood. Cytogenetic studies in lymphomas show that cytogenic abnormalities, including chromosomal translocation, can be found in this group, but more studies will be needed to assess the frequency of these events.

Analysis of Aurora B kinase in non-Hodgkin lymphoma.  

PubMed

This study explored the levels of Aurora B, a key regulator of mitosis, in 71 lymph nodes and tumor specimens excised operatively from individuals with various types of non-Hodgkin lymphoma (NHLs). Immunohistochemical examination found that diffuse large B-cell lymphoma (10/21, 48%) and Burkitt lymphoma (BL) (6/7, 86%) cells highly (percentage of positive cells, >20%) expressed Aurora B in their nuclei. On the other hand, none of the low-grade B-cell lymphoma (n=20), except for one case of follicular lymphoma, highly expressed this protein kinase, suggesting that levels of Aurora B correlated with histological grade in B-cell NHLs (P<0.01). Exposure of BL/leukemia cells to AZD1152-HQPA in vitro, a selective inhibitor of Aurora B kinase, potently induced growth arrest and apoptosis in a caspase-dependent, as well as -independent manner. Moreover, AZD1152 synergistically enhanced the effects of vincristine (VCR) to induce growth arrest of these cells. Further experiments found that VCR increased levels of the p-Aurora B through the activation of c-Jun N-terminal kinase, which was blocked in the presence of AZD1152-HQPA. PMID:19823168

Proteolytic activity of human non-Hodgkin's lymphomas.  

PubMed Central

This study was conducted to assess the net proteolytic activity of human non-Hodgkin's lymphomas (NHLs). We have compared the extracellular matrix (ECM)-degradative abilities of human NHLs, reactive lymphoid hyperplasias, and established lymphoid cell lines using Matrigel invasion and elastin degradation assays. The inhibition studies allowed identification of the classes of proteinases involved in ECM degradation. Our results indicate that lymphocytes and other leukocytes derived from both human NHLs and reactive lymphoid hyperplasias are capable of Matrigel penetration, but only cells derived from the high-grade human NHLs degrade elastin in vitro. Established lymphoid cell lines (both malignant and Epstein-Barr virus immortalized) do not produce MMP-9, do not penetrate the Matrigel, and do not degrade elastin. Moreover, in human NHLs, elastolytic activity is blocked by metalloproteinase inhibitors, while inhibitors of the other classes of proteolytic enzymes have only minor effects. This study identifies metalloproteinases as the most important class of proteinases involved in ECM degradation by NHLs. The previous studies suggest that, within this class, MMP-9 represents the key enzyme that plays a role in the biological aggressiveness of human NHLs.

[Non Hodgkin lymphoma of the sigmoid colon: case report].  

PubMed

Non-Hodgkin lymphoma (NHL) occurs in extranodal location in approximately 20% of patients with limited stage, high-grade disease. Colon is infrequently involved as a primary location, accounting for 4% of all extranodal NHL and far less than 1% of all colonic malignancies. Colonic NHL differs significantly in terms of presentation, therapy and outcome relative to other more common gastrointestinal sites, like stomach or small bowel. The most common location is the cecum (60-74% of cases), while the sigmoid is involved in 2.5-14%. Largely related to the lack of specific signs and symptoms, patients frequently present advanced locoregional disease. Moreover, more than half of patients require an emergent surgery, usually due to pain, bleeding, or obstruction. Therapy usually involves resection of the affected colon and regional lymph nodes followed by adjuvant chemotherapy or/and radiotherapy. Utilizing this approach 5 years survival rates range between 27-55%. We present a 59 years old man with weight loss,abdominal pain, palpable mass and intestinal obstruction. A sigmoidectomy was realized with histopathologic report of NHL. Systemic adjuvant chemotherapy and abdominal radiation were administered. After a 6 month follow-up from initial procedure he is now asymptomatic with Karnofsky of 90. Therefore a surgeon should consider the possibility of NHL when evaluating such patients. PMID:19666296

Testicular function following the treatment of Hodgkin's disease in childhood.  

PubMed Central

Testicular function was studied in 40 males treated in childhood for Hodgkin's disease at St Bartholomew's Hospital, and the Hospital for Sick Children, London, between 1971-1985. All patients were 16 years or over at evaluation, and off treatment more than 6 years. Basal FSH, LH and testosterone levels were measured. Testicular size was measured using a Prader orchidometer, and all patients were offered a seminal analysis. Twenty-eight patients were treated with chemotherapy, usually ChlVPP. Twenty-one also had radiotherapy, five below the diaphragm. Twelve patients were treated with radiotherapy alone (five below the diaphragm). Twenty-six of 28 patients treated with chemotherapy and three of five patients treated with radiotherapy alone below the diaphragm have elevated basal FSH levels, and 18 of these also have elevated basal LH levels. Median testicular volume is 11 ml (range 5-25 ml). Eleven of 13 patients investigated are azoospermic. All patients have normal testosterone levels, and normal secondary sexual characteristics. There is no biochemical evidence of healing of the damaged germinal epithelium with elevated FSH levels persisting up to 17 years from the end of therapy. These results indicate a high incidence of damage to the germinal epithelium in patients treated with ChlVPP chemotherapy and/or radiotherapy below the diaphragm. Appropriate counselling of these patients with regard to their reproductive capabilities is essential. PMID:8260374

Late cardiopulmonary toxicity after treatment for Hodgkin's disease.  

PubMed Central

Cardiac and pulmonary functions were evaluated in 75 patients aged 50 years or under, treated for Hodgkin's disease by mantle radiotherapy at least 3 years earlier; all received the same mantle field radiotherapy: radiotherapy alone, MOPP chemotherapy plus radiotherapy, MOPP and ABVD chemotherapy plus radiotherapy. No patient had any symptom of heart disease. Only borderline abnormalities of ECG or echocardiogram were observed in 12 patients. One of them showed a moderate aortic stenosis which was known before the treatment; apical or septum hypokinesia were present in four patients and one patient had a slightly right ventricular dilatation. Twelve (16%) chest radiographs showed moderate or severe abnormalities, but there was no significant correlation between the results of pulmonary function tests and Xenon ventilation/perfusion scintigraphy, the clinical examination and the intensity of the radiological sequelae. Twenty-nine (64%) Xenon scintigraphies showed a reduction of lung perfusion in the irradiated areas without any symptom. The resting mean pulmonary function test was significantly lower for the patients than for the control group with regard to Total Capacity and Vital Capacity. The exercise tolerance, as indicated by analysis of blood gases, was below the one expected for only two patients who were dyspneic during the low level of exercise. We did not find any significant difference between the three treatment groups. We conclude that the treatment with mantle field under good technical conditions (high energy photons, moderate doses...) can result in minimal cardiopulmonary dysfunction. PMID:1616862

The ISI distribution of the stochastic Hodgkin-Huxley neuron  

PubMed Central

The simulation of ion-channel noise has an important role in computational neuroscience. In recent years several approximate methods of carrying out this simulation have been published, based on stochastic differential equations, and all giving slightly different results. The obvious, and essential, question is: which method is the most accurate and which is most computationally efficient? Here we make a contribution to the answer. We compare interspike interval histograms from simulated data using four different approximate stochastic differential equation (SDE) models of the stochastic Hodgkin-Huxley neuron, as well as the exact Markov chain model simulated by the Gillespie algorithm. One of the recent SDE models is the same as the Kurtz approximation first published in 1978. All the models considered give similar ISI histograms over a wide range of deterministic and stochastic input. Three features of these histograms are an initial peak, followed by one or more bumps, and then an exponential tail. We explore how these features depend on deterministic input and on level of channel noise, and explain the results using the stochastic dynamics of the model. We conclude with a rough ranking of the four SDE models with respect to the similarity of their ISI histograms to the histogram of the exact Markov chain model. PMID:25339894

Isolated III cranial nerve palsy: a Hodgkin's lymphoma?  

PubMed

A 69-year-old woman developed ptosis and diplopia due to an isolated pupil-involving left oculomotor nerve palsy. General examination was unremarkable. Initial workup showed a mild increase in cerebrospinal fluid proteins. Imaging studies were remarkable for a left oculomotor nerve enhancement in brain MRI and hyperfixation along the nerve's pathway in full body single-photon emission CT. Assuming the possible diagnosis of neurosarcoidosis, the patient was started on high-dose methylprednisolone. Three months later she developed pancytopenia. A bone marrow biopsy was performed and histopathology revealed infiltration by Hodgkin's lymphoma. Adriamycin, bleomycin, vinblastine, dacarbazine protocol chemotherapy was started and full haematological remission obtained after four cycles, despite mild oculomotor nerve palsy persisted. Isolated oculomotor palsy as the first presenting manifestation of a lymphoma is rare and alternative differential diagnosis must be considered in the absence of other lymphoma manifestations.

Infradiaphragmatic Hodgkin's disease: long term results of combined modality therapy.  

PubMed

Hodgkin's disease (HD) confined below the diaphragm accounts for less than 5% of all patients with HD. Although the major characteristics of this presentation appear established, optimal modalities of treatment still remain difficult to define. From April 1972 to October 1988, 28 patients with newly diagnosed infra-diaphragmatic HD, clinical stages I or II have been treated with 3 successive prospective protocols combining initial chemotherapy and radiotherapy (40 gy). This series of patients accounted for 4,3% of patients with HD limited to clinical stages (CS) I and II. Overall survival and freedom from relapse at 15 years were 74,4% and 73% respectively, without significant differences between clinical stages I and II, presence or absence of B symptoms or histologic subtype. There is only a trend (p < 0,10) in favour of patients younger than 40 years. In all 7 clinically staged IA patients no relapses were seen and combined treatment does not appear to be better than inverted Y irradiation alone. On the other hand initial chemotherapy seems necessary in patients with CS II A and B since 15 of our 21 patients are alive in first CR whereas the crude rate of transdiaphragmatic nodal relapses may reach up to 53% following radiotherapy alone.

Protrusion-guided extracellular vesicles mediate CD30 trans-signalling in the microenvironment of Hodgkin's lymphoma.  

PubMed

Classical Hodgkin's lymphoma (cHL)-affected lymphoid tissue contains only a few malignant Hodgkin and Reed-Sternberg (HRS) cells, which are disseminated within a massive infiltrate of reactive cells. In particular, the innate immune infiltrate is deemed to support tumour growth by direct cell-cell interaction. Since they are rarely found in close proximity to the malignant cells in situ, we investigated whether cHL-derived extracellular vesicles might substitute for a direct cell-cell contact. We studied the crosstalk of the transmembrane proteins CD30 and CD30 ligand (CD30L) because they are selectively expressed on HRS and innate immune cells, respectively. Here, we showed that HRS cells released both the ectodomain as a soluble molecule (sCD30) and the entire receptor on the surface of extracellular vesicles. The vesicle diameter was 40-800 nm, as determined by cryo- and immune electron microscopy. In addition to CD30, typical extracellular vesicle markers were detected by mass spectrometry and flow cytometry, including tetraspanins, flotillins, heat shock proteins and adhesion molecules. In contrast to sCD30, vesicles caused a CD30-dependent release of interleukin-8 in CD30L(+) eosinophil-like EoL-1 cells and primary granulocytes from healthy donors, underscoring the functionality of CD30 on vesicles. In extracellular matrix (ECM)-embedded culture of HRS cells, a network of actin and tubulin-based protrusions guided CD30(+) vesicles into the micro-environment. This network targeted CD30(+) vesicles towards distant immune cells and caused a robust polarization of CD30L. Confocal laser scanning microscopy of 30 µm sections showed a CD30 vesicle-containing network also in cHL-affected lymphoid tissue of both mixed-cellularity and nodular sclerosing subtypes. This network might facilitate the communication between distant cell types in cHL tissue and allow a functional CD30-CD30L interaction in trans. The tubulin backbone of the network may provide a target for the therapy of cHL with antitubulin-based CD30 antibody constructs. PMID:24659185

Thoracic CT scanning for mediastinal Hodgkin's disease: results and therapeutic implications  

SciTech Connect

Thoracic CT scans were performed on 42 newly diagnosed patients with Hodgkin's disease. Five of 10 patients with negative chest X ray (CXR) had abnormal thoracic CT scans. Among the remaining 32 patients with mediastinal Hodgkin's disease (MHD) on CXR, pericardial (Ep) and chest wall invasion (Ec) were the two most common sites of involvement which were detectable by CT scan alone. Ep and Ec accounted for 16 of 19 of the changes in treatment portal or philosophy based on CT scan findings. Because of the high risk of cardiac or pulmonary radiation toxicity in Ep or Ec, radiation treatment alone may be inadequate. Treatment of mediastinal Hodgkin's disease is reviewed here. The use of CT scans for identification of Ep, Ec, and other abnormalities will allow for more precise treatment, further define the use of conventional radiotherapy, combined modality therapy or whole lung irradiation, and allow more accurate analysis of treatment results.

Entrainment and chaos in a pulse-driven Hodgkin-Huxley oscillator  

E-print Network

The Hodgkin-Huxley model describes action potential generation in certain types of neurons and is a standard model for conductance-based, excitable cells. Following the early work of Winfree and Best, this paper explores the response of a spontaneously spiking Hodgkin-Huxley neuron model to a periodic pulsatile drive. The response as a function of drive period and amplitude is systematically characterized. A wide range of qualitatively distinct responses are found, including entrainment to the input pulse train and persistent chaos. These observations are consistent with a theory of kicked oscillators developed by Qiudong Wang and Lai-Sang Young. In addition to general features predicted by Wang-Young theory, it is found that most combinations of drive period and amplitude lead to entrainment instead of chaos. This preference for entrainment over chaos is explained by the structure of the Hodgkin-Huxley phase resetting curve.

In vivo somatic mutation in the lymphocytes of Hodgkin's disease patients  

SciTech Connect

While current medical therapies for Hodgkin's disease are usually quite effective, it has become increasingly clear that some of the therapies utilized carry an inherent risk for the induction of secondary malignancies. In order to examine the cellular and genetic responses to therapy for Hodgkin's disease among individuals, the authors have determined the mutant frequency of T-lymphocytes in 3 cohorts of patients and in controls using a T-cell cloning assay selecting for 6-thioguanine resistance. Overall, the results indicated that the individual response to Hodgkin's disease therapy was a heterogeneous one with a sub-population of persons having elevated mutant frequencies even many years after their last treatment. The larger frequency of elevated MFs in those patients who received intensive therapy (chemotherapy and radiotherapy) is consistent with their increased risk for second cancer induction.

Entanglement in the classical limit: Quantum correlations from classical probabilities  

SciTech Connect

We investigate entanglement for a composite closed system endowed with a scaling property which allows the dynamics to be kept invariant while the effective Planck constant ({Dirac_h}/2{pi}){sub eff} of the system is varied. Entanglement increases as ({Dirac_h}/2{pi}){sub eff}{yields}0. Moreover, for sufficiently low ({Dirac_h}/2{pi}){sub eff} the evolution of the quantum correlations, encapsulated, for example, in the quantum discord, can be obtained from the mutual information of the corresponding classical system. We show this behavior is due to the local suppression of path interferences in the interaction that generates the entanglement.

Three approaches to classical thermal field theory  

SciTech Connect

Research Highlights: > Classical thermal field theory admits three equivalent path integral formulations. > Classical Feynman rules can be derived for all three formulations. > Quantum Feynman rules reduce to classical ones at high temperatures. > Classical Feynman rules become much simpler when superfields are introduced. - Abstract: In this paper we study three different functional approaches to classical thermal field theory, which turn out to be the classical counterparts of three well-known different formulations of quantum thermal field theory: the closed-time path (CTP) formalism, the thermofield dynamics (TFD) and the Matsubara approach.

Dementia studies in Chinese populations.  

PubMed

Variations in the prevalence of dementia in different ethnic groups have been reported worldwide, and a number of reviews have provided a picture of epidemiological studies in dementia research. However, little is known about epidemiological studies in Chinese populations. In this review, we searched PubMed and the Web of Science for original research articles published in English up to July 2013 on the prevalence, incidence, risk factors, and prognosis of dementia in Chinese populations worldwide. Except for the prevalence, we included only population-based follow-up studies. We identified 25 studies in elderly Chinese residents in Mainland China, Hong Kong, Taiwan, and Singapore, and found a higher prevalence of dementia in Mainland China than in the other locations, which may be due to that the studies from Mainland China are more recent than those from other locations. A notable increase in incidence was observed when dementia cases were diagnosed using 10/66 diagnostic criteria compared to other criteria. Studies on risk factors for dementia were limited and mostly from Mainland China. Age, gender, education, smoking, and alcohol consumption were related to the risk of dementia in Chinese populations. Only two prognostic studies were identified, and age, gender, and residential area were related to the prognosis of dementia. In conclusion, the prevalence, incidence, and risk factors for dementia found in Chinese populations were comparable to other ethnic groups, but no conclusive results on prognosis were found. The differences in prevalence and incidence were influenced by the diagnostic criteria and the time of study. Longitudinal population-based studies on the incidence, risk factors, and prognosis of dementia in Chinese populations are required. PMID:24627330

Second neoplasms in patients with Hodgkin's disease following combined modality therapy--the Yale experience  

SciTech Connect

From 1969 to 1982, 183 patients with previously untreated stages IIIB and IV Hodgkin's disease and relapsing Hodgkin's disease after radiation therapy were treated with combination chemotherapy plus low-dose irradiation (CRT). One hundred fifty patients who achieved a complete response (CR) were analyzed for risk of developing a second neoplasm. Median follow-up has been 8.3 years. Actuarial survival of all patients is 74% at 10 years with a relapse-free survival of 68%. An additional 24 patients with stage IIIA disease were also treated with CRT. There were 22 CRs at risk who were analyzed. Median follow-up has been 3+ years with an actuarial survival of 90% at five years and a relapse-free survival of 83%. Second neoplasms have developed in 14 of 172 patie
