Satisfactory functional outcomes following bronchoscopic lung volume reduction (BLVR) using endobronchial valves (EBVs) depend on the absence of collateral ventilation (CV) between the target and adjunct lobes. The Chartis system has proven to be useful for determining whether CV is present or absent, but this system can also erroneously indicate the absence of CV, which can lead to BLVR failure. Here, we describe low-flow Chartis phenotype in the target lobe resulted in difficult judgment of existence of CV...

PURPOSE: Extranodal natural killer/T-cell lymphoma (ENKTL), nasal-type, is a distinct subtype of non-Hodgkin lymphoma. ENKTL is sensitive to radiotherapy, but the prognosis is poorer than those of other types of early stage lymphoma. To date, optimal treatment strategies for patients with early stage ENKTL have not been fully defined. METHODS: We retrospectively investigated the efficacy and safety of pegaspargase, gemcitabine, and oxaliplatin (P-GEMOX) combined with different dose radiotherapy (RT) in the treatment of 35 newly diagnosed, stage IE to IIE ENKTL patients at our institution from October 2011 to September 2015...

Lymphomas arising in the adrenal are rare, and to our knowledge, 2 cases of Epstein-Barr virus (EBV)-positive diffuse large B-cell lymphomas (DLBCL) in an adrenal pseudocyst have been reported. We report an incidental EBV-positive DLBCL arising in an adrenal pseudocyst in a 58-year-old man with a 7-year history of lymphoplasmacytic lymphoma (LPL). The DLBCL was present in the fibrinous exudate, while the LPL resided in the cyst wall. The patient underwent de-roofing of the same cyst 3 years previously; review of histology revealed foci of LPL in the cyst wall, but not of DLBCL...

Hodgkin and non-Hodgkin lymphoma are both good targets for immunotherapy, as they are accessible to antibodies and cell-based immunotherapy, express costimulatory molecules, and express lineage-restricted, viral, and unique tumor antigens. Blockade of the programmed-death 1 (PD-1) immune checkpoint has produced very encouraging response rates in patients with Hodgkin lymphoma, whereas adoptive transfer of Epstein-Barr Virus (EBV)-specific T cells has shown clinical activity in patients with posttransplant lymphoma and other EBV-associated lymphomas...

BACKGROUND: . Numbers of blood leukocyte subsets are highly dynamic in childhood and differ greatly between individuals. Inter-individual variation is only partly accounted for by genetic factors. OBJECTIVE: Determine which nongenetic factors affect the dynamics of innate leukocytes, and naive and memory lymphocyte subsets. METHODS: . We performed six-color flow cytometry and linear mixed effect modeling to define the dynamics of 62 leukocyte subsets from birth to 6 years of age in 1,182 children with one to five measurements per individual...

PURPOSE OF REVIEW: Post-transplant lymphoproliferative disease (PTLD) is a major complication of hematopoietic stem cell and solid organ transplantation. The incidence of transplantation in childhood has been steadily rising, making PTLD the most common form of lymphoproliferation in childhood. The purpose of this review is to summarize the role of the Epstein-Barr virus (EBV) in the pathophysiology and discuss the management of PTLD. RECENT FINDINGS: More than 90% of pediatric PTLD is EBV-positive...

A 41-year-old man was referred to our hospital for treatment of anaplastic lymphoma kinase (ALK)-negative anaplastic large cell lymphoma. Chronic active Epstein-Barr virus (CAEBV) was diagnosed based on the findings of elevated EBV antibody titers and positive EBV-DNA in the peripheral blood, and cord blood stem cell transplantation (CBT) was performed. The EBV-DNA levels in the blood fell below the limit of detection. His lymphoma relapsed on Day 165 with the appearance of eruptions, which disappeared after the withdrawal of tacrolimus...

ChIP-seq performed on lymphoblastoid cell lines (LCLs), expressing epitope-tagged EBNA3A, EBNA3B or EBNA3C from EBV-recombinants, revealed important principles of EBNA3 binding to chromatin. When combined with global chromatin looping data, EBNA3-bound loci were found to have a singular character, each directly associating with either EBNA3-repressed or EBNA3-activated genes, but not with both. EBNA3A and EBNA3C showed significant association with repressed and activated genes. Significant direct association for EBNA3B loci could only be shown with EBNA3B-repressed genes...

: Recently, Linear Ubiquitin Assembly Complex (LUBAC)-mediated linear ubiquitination has come into focus due to its emerging role in activation of NFκB in different biological contexts. However, the role of LUBAC in LMP1 signaling leading to NFκB and IRF7 activation has not been investigated. We have shown here that RNF31, the key component of LUBAC complex, interacts with LMP1 and IRF7 in EBV-transformed cells, and that LUBAC stimualtes linear ubiquitination of NEMO and IRF7. Consequently, LUBAC is required for LMP1 signaling to full activation of NFκB, but inhibits LMP1-stimulated IRF7 transcriptional activity...

EBI2 is an important chemotactic receptor that is involved in proper B-cell T-cell interactions. Epstein-Barr Virus (EBV) has been shown to upregulate this gene upon infection of cell lines, but the timing and mechanism of this upregulation, as well as its importance to EBV infection, remain unknown. This work investigated EBV's manipulation of EBI2 expression of primary naïve B cells. EBV infection induces EBI2 expression resulting in elevated levels of EBI2 after 24 hours until 7 days post-infection, followed by a dramatic decline (p = 0...

Cancer-initiating cells (CICs) are specialized cells that have the ability to self-renew and are multipotent. We recently demonstrated that Forkhead box O3a (FoxO3a)-expressing cells exhibited a CIC-like potential in Hodgkin's lymphoma (HL). A proportion of HL patients are infected with Epstein-Barr virus (EBV). EBV-encoded latent membrane protein (LMP) 1 downregulates FoxO3a, suggesting that FoxO3a expression may be abolished in EBV-positive HL. Inhibitors of DNA-binding (ID) proteins are highly conserved transcription factors mediating stem cell functions...

In sheep and goat breeding programs, the proportion of females for which the sire is known (known paternity rate [KPR]) can be very low. In this context, paternity assignment using SNP is an attractive tool. The annual genetic gain (AGG) is impacted by the accuracy of the EBV. In populations with a low KPR, the number of known relatives for a given individual is low, and the EBV that are based on this information are imprecise. However, the impact of partially known paternal filiations, in terms of potential genetic and economic losses, has never been quantitatively evaluated in situations where natural mating is the main reproductive mode...

Most breeding companies evaluate economically important traits in males and females as a single trait, assuming genetic correlation of 1 between phenotypes measured in both sexes. This assumption may not be true because genes may be differently expressed in males and females. We estimated genetic correlations between males and females for growth and efficiency traits in broiler chickens, growth traits in American Angus beef cattle, and birth weight and preweaning mortality in purebred pigs; therefore, each trait was treated differently in males and females...

Endocrine fertility traits, defined from progesterone concentration levels in milk, have been suggested as alternative indicators for fertility in dairy cows because they are less biased by farm management decisions and more directly reflect a cow's reproductive physiology than classical traits derived from insemination and calving data. To determine the potential use of endocrine fertility traits in genomic evaluations, the improvement in accuracy from using endocrine fertility traits concurrent with classical traits in the genomic prediction of fertility was quantified...

We introduce an innovative approach to lowering the overall cost of obtaining genomic EBV (GEBV) and encourage their use in commercial extensive herds of Brahman beef cattle. In our approach, the DNA genotyping of cow herds from 2 independent properties was performed using a high-density bovine SNP chip on DNA from pooled blood samples, grouped according to the result of a pregnancy test following their first and second joining opportunities. For the DNA pooling strategy, 15 to 28 blood samples from the same phenotype and contemporary group were allocated to pools...

Kaposi's sarcoma-associated herpesvirus (KSHV), the causative agent of Kaposi's sarcoma, encodes 25 mature viral miRNAs. MCP-1-induced protein-1 (MCPIP1), a critical regulator of immune homeostasis, has been shown to suppress miRNA biosynthesis via cleavage of precursor miRNAs through its RNase domain. We demonstrate that MCPIP1 can directly cleave KSHV and EBV precursor miRNAs and that MCPIP1 expression is repressed following de novo KSHV infection. In addition, repression with siRNAs to MCPIP1 in KSHV-infected cells increased IL-6 and KSHV miRNA expression, supporting a role for MCPIP1 in IL-6 and KSHV miRNA regulation...

Effusion-based lymphoma is a rare and unique type of large B-cell lymphoma presenting in effusion without a mass lesion. It shares many clinicopathological features with primary effusion lymphoma (PEL), but is distinct from PEL by the absence of HHV8 association. Double hit lymphoma (DHL) is an aggressive B-cell lymphoma, defined by concurrent rearrangement of MYC and BCL2 or BCL6. DHL often presents as lymphadenopathy or an extranodal mass, but rarely occurs in effusion. Here we report a 61-year-old male with alcoholic cirrhosis presenting as massive ascites and left pleural effusion...

A growing body of evidence suggests that angiogenesis plays a crucial role in the pathogenesis of multiple sclerosis (MS). Animal models of MS show a significant improvement when the process of angiogenesis is halted. In this study, we measured the serum levels of vascular-endothelial growth factor (VEGF), soluble Endoglin (sEng), angiopoietin 1(Ang-1), angiopoietin 2 (Ang-2), and uric acid (UA) as well as serum anti-Epstein-Barr virus (EBV) EBNA-1 IgG in 50 MS patients (including 20 newly diagnosed and 30 patients taking IFN-beta for >6months) and 40 healthy individuals...
