Abstract
Breast cancer is the most common malignancy in women in the United States and is second only to lung cancer as a cause of cancer death. The overall management of breast cancer includes the treatment of local disease with surgery, radiation therapy, or both, and the treatment of systemic disease with cytotoxic chemotherapy, endocrine therapy, biologic therapy, or combinations of these. This portion of the NCCN Guidelines discusses recommendations specific to the locoregional management of clinical stage I, II, and IIIA (T3N1M0) tumors.

Abstract
The trace elements metabolism has been reported to possess specific roles in the pathogenesis and progress of diabetes mellitus. Due to the continuous increase in the population of patients with Type 2 diabetes (T2D), this study aims to assess the levels and inter-relationships of fast blood glucose (FBG) and serum trace elements in Type 2 diabetic patients. This study was conducted on 40 Egyptian Type 2 diabetic patients and 36 healthy volunteers (Hospital of Tanta University, Tanta, Egypt). The blood serum was digested and then used to determine the levels of 24 trace elements using an inductive coupled plasma mass spectroscopy (ICP-MS). Multivariate statistical analysis depended on correlation coefficient, cluster analysis (CA) and principal component analysis (PCA), were used to analysis the data. The results exhibited significant changes in FBG and eight of trace elements, Zn, Cu, Se, Fe, Mn, Cr, Mg, and As, levels in the blood serum of Type 2 diabetic patients relative to those of healthy controls. The statistical analyses using multivariate statistical techniques were obvious in the reduction of the experimental variables, and grouping the trace elements in patients into three clusters. The application of PCA revealed a distinct difference in associations of trace elements and their clustering patterns in control and patients group in particular for Mg, Fe, Cu, and Zn that appeared to be the most crucial factors which related with Type 2 diabetes. Therefore, on the basis of this study, the contributors of trace elements content in Type 2 diabetic patients can be determine and specify with correlation relationship and multivariate statistical analysis, which confirm that the alteration of some essential trace metals may play a role in the development of diabetes mellitus.

Abstract
Background There is increasing interest in using cancer vaccines to treat breast cancer patients in the adjuvant setting to prevent recurrence in high risk situations or in combination with other immunomodulators in the advanced setting. Current peptide vaccines are limited by immunologic compatibility issues, and engineered autologous cellular vaccines are difficult to produce on a large scale. Using standardized bystander cell lines modified to secrete immune stimulating adjuvant substances can greatly enhance the ability to produce immunogenic cellular vaccines using unmodified autologous cells or allogeneic medical grade tumor cell lines as targets. We investigated the efficacy of a cellular vaccine using B78H1 bystander cell lines engineered to secrete granulocyte macrophage-colony stimulating factor and CD40 ligand (BCG) in a murine model of breast cancer. Methods Five-week-old female BALB/c mice were injected orthotopically in the mammary fat pad with 4T1 tumor cells. Treatment consisted of irradiated 4T1 ± BCG cells given subcutaneously every 4 days and was repeated three times per mouse when tumors became palpable. Tumors were measured two to three times per week for 25 days. The vaccine’s activity was confirmed in a second experiment using Lewis lung carcinoma (LLC) cells in C57BL/6 mice to exclude a model specific effect. Interferon-γ (IFN-γ) and interleukin-2 (IL-2) enzyme-linked immunospots (ELISPOTS) were performed on splenic lymphocytes incubated with 4T1 lysates along with immunohistochemistry for CD3 on tumor sections. Results Tumor growth was significantly inhibited in the 4T1-BCG and LLC-BCG treatment groups when compared to 4T1 and LLC treatment groups. There were higher levels of IL-2 and IFN-γ secreting T-cells on ELISPOT for BCG treated groups, and a trend for higher numbers of tumor infiltrating CD3+ lymphocytes. Some tumors in the 4T1-BCG demonstrated organized lymphoid structures within the tumor microenvironment as well. Conclusion The use of BCG bystander cell lines demonstrates proof of concept for anti-tumor activity and immunogenicity in an immunocompetent murine model of breast cancer. This vaccine is being evaluated in lung cancer and should be explored further in clinical trials of breast cancer patients at high risk of recurrence or in combination with other immunomodulatory agents.

Abstract
Immune checkpoint inhibitors produce durable long-term survival in some patients with advanced melanoma and lung cancer. Better immune targets and combination strategies can harness the immune system by supporting the three elements of a successful T-cell antitumor response: (A) generation of sufficient numbers of antitumor T cells within the lymphoid compartment; (B) effective T-cell trafficking and extravasation out of the lymphoid compartment, through the bloodstream, and into the tumor microenvironment; and (C) T-cell effector function within the tumor microenvironment that is characterized by the ability to bypass immune checkpoints, soluble and metabolic inhibitory factors, and inhibitory cells. Strategies that hold promise include dual immune checkpoint blockade, as well as the combination of immune checkpoint blockade with costimulatory receptor agonists, enhancers of innate immunity, inhibition of indoleamine 2,3-dioxygenase, adoptive T-cell transfer/T-cell engineering, therapeutic vaccines, small-molecule inhibitors, and radiation therapy. Novel, rational clinical trial designs seek to combine targeted agents and one or more immune checkpoint inhibitors, with the goal of producing deep and durable antitumor responses, which thus far have been observed in only a minority of patients.

Abstract
A new species of the genus Thelohanellus Kudo, 1933 (Myxosporea, Bivalvulida) was isolated from the fins of goldfish Carassius auratus auratus (Linnaeus 1758). The fish had been imported from China by an Austrian retailer. Nodules from the margins of the fins contained pyriform myxospores with a singular polar capsule. In valvular view, the spores measured 12.2 µm in length and 6.4 µm in width. In sutural view, the thickness was 2.9 µm. The polar capsule measured 4.2 × 3.1 µm and contained a polar filament with 8 to 9 coils. Histological sections showed plasmodia of 0.2 to 4.0 mm diameter with the earlier developmental stages of the parasite in the periphery and the mature spores closer to the center. In the transmission electron microscope examination, the different developmental stages could be observed. Morphological data, host specificity, tissue tropism, and molecular analysis of the small subunit rDNA identify this parasite as a new species of Thelohanellus, which we have named Thelohanellus hoffmanni sp. nov.

Abstract
Abstract
Background:
Gene expression profiling in breast cancer offers the potential to improve prognostic accuracy, treatment choice, and health outcomes in women diagnosed with early-stage breast cancer. Numerous gene-profiling assays are now available, which can be applied to a single tumor specimen to provide physicians with a more complete basis for treatment decisions.
• MammaPrint is 70-gene profile to estimate whether patients are at high or low risk of developing metastases within the first 10 years after curative surgery.
• BluePrint is an 80-gene molecular subtyping profile that discriminates between three breast cancer subtypes: Luminal, HER2, and Basal.
• TargetPrint provides a quantitative measurement of estrogen receptor (ER), progesterone receptor (PR), and HER2.
• Oncotype DX measures expression of five reference genes and 16 cancer-related genes, quantifying the risk of distant recurrence in patients with ER+ early breast cancer who are treated with adjuvant hormonal therapy.
Trial design:
PROMIS is a prospective study that will investigate the additional value of MammaPrint, BluePrint and TargetPrint in women with an intermediate Oncotype DX score. An initial CRF – capturing baseline patient characteristics, pathology information, Oncotype DX score and the recommended treatment plan – will be completed before receiving the MammaPrint result. A second CRF – capturing the actual treatment – will be completed within 4 weeks after receiving the MammaPrint result.
Eligibility: The study will include women aged ≥18 years with histologically proven invasive stage I-II, node negative or node positive (N1), hormone receptor positive, HER2 negative breast cancer, who received an Oncotype DX intermediate score (18-30) and who signed informed consent.
Objectives:
Primary objective:
Assess the impact of MammaPrint on chemotherapy + endocrine versus endocrine alone treatment decisions in lymph node negative, hormone receptor positive, HER2 negative breast cancer patients, who received an Oncotype DX intermediate score (18-30)
Secondary objectives:
• Assess the impact of MammaPrint on chemotherapy + endocrine versus endocrine alone treatment decisions in lymph node positive (N1), hormone receptor positive, HER2 negative breast cancer patients, who received an Oncotype DX intermediate score (18-30)
• Assess the distribution of MammaPrint Low and High Risk in patients with an intermediate recurrence score
• Assess concordance of TargetPrint ER, PR and HER2 results with Oncotype DX ER, PR and Her2 and with locally assessed IHC/FISH ER, PR and HER2
• Compare clinical subtype based on IHC/FISH ER, PR, HER2 and Ki-67 (if available) with BluePrint molecular subtype
Statistical methods:
A sample size of 820 lymph node negative, hormone receptor positive, HER2 negative breast cancer patients is required to detect a 20% overall treatment change (5% significance and 90% power). A McNemars test will be performed for the comparison of the two proportions treated (before and after), both expressed as a percentage.
Accrual: A total of 385 out of 820 have been enrolled from multiple institutions.

Abstract
Myxozoans, a diverse group of microscopic obligate endoparasites, can cause diseases in a number of economically important fish, including the marbled spinefoot Siganus rivulatus. To date, only 1 myxozoan, Zschokkella helmii, has been reported to infect S. rivulatus. Here we describe another myxozoan detected in S. rivulatus. Investigations of 40 marbled spinefoot fish caught from the Red Sea coast, Jeddah, Saudi Arabia, revealed clusters of parasitic spores in the kidney. Light microscope examination of the native spores revealed sub-spherical, mature spores with smooth shell valves. The 2 polar capsules were equal in size, and the polar filament was perpendicular to the longitudinal axis of the polar capsules. Histopathological examinations of the infected kidneys demonstrated the presence of both spores and developmental stages in the lumen of the renal tubules without any pathological effect. Electron microscopy investigations showed maturing spores composed of 2 valvogenic cells, each with a prominent nucleus. The valvogenic cells enclosed 2 polar capsules containing 3 filament coils as well as a binucleated sporoplasm cell filling the space between and beneath the 2 polar capsules. BLAST search analysis of the amplified sequence from the detected parasite indicated a high percent of identity to the 18S rDNA genes of different myxosporean species. Phylogenetic analysis placed the detected parasite within a clade of Ortholinea sp. (AL-2006). Based on the results of the light and electron microscopy, histopathological, and molecular investigations, the detected parasite was identified as a myxosporean parasite belonging to the genus Ortholinea and designated as O. saudii sp. nov.

Abstract
Spring viraemia of carp virus (SVCV) is an aetiological agent of a serious disease affecting carp farms in Europe and is a member of the Rhabdoviridae family of viruses. The genome of SVCV codes for five proteins: nucleoprotein (N), phosphoprotein (P), matrix protein (M), glycoprotein (G) and RNA-dependent RNA polymerase (L). RNA-mediated interference (RNAi) by small interfering RNAs (siRNAs) is a powerful tool to inhibit gene transcription and is used to study genes important for viral replication. In previous studies regarding another member of Rhabdoviridae, siRNA inhibition of the rabies virus nucleoprotein gene provided in vitro and in vivo protection against rabies. In this study, synthetic siRNA molecules were designed to target SVCV-N and SVCV-P transcripts to inhibit SVCV replication and were tested in an epithelioma papulosum cyprini (EPC) cell line. Inhibition of gene transcription was measured by real-time quantitative reverse-transcription PCR (RT-qPCR). The efficacy of using siRNA for inhibition of viral replication was analysed by RT-qPCR measurement of a reporter gene (glycoprotein) expression and by virus endpoint titration. Inhibition of nucleoprotein and phosphoprotein gene expression by siRNA reduced SVCV replication. However, use of tandem siRNAs that target phosphoprotein and nucleoprotein worked best at reducing SVCV replication.

Abstract
Background Aeromonas salmonicida is a major fish pathogen associated with mass mortalities in salmonid fish. In the present study, we applied In Vivo Induced Antigen Technology (IVIAT), a technique that relies on antibodies adsorbed against in vitro cultures of the pathogen, to a clinical isolate of A. salmonicida subsp. salmonicida. Results The results from IVIAT allowed identification of four proteins that were upregulated in the fish samples: A UDP-3-O-acyl-N-acetylglucosamine deacetylase, an RNA polymerase sigma factor D as well as TonB and a hypothetical protein. Subsequent investigations were performed using real-time PCR and cDNA synthesised from infected spleen, liver and anterior kidneys. These confirmed that the transcription level of each of these genes was significantly upregulated during the infection process compared to bacteria in vitro. Conclusions The present studied identified four genes that were upregulated during the infectious process and are likely to play a role in the virulence of A. salmonicida. Because these are antigenic they might constitute potential targets for the development of new vaccine as well as therapeutic agents.

Abstract
During a fish health inspection in the Viennese waterway 'Old Danube', a virus was isolated exclusively from white bream Blicca bjoerkna (L.) (formerly Abramis bjoerkna L.), one of the most abundant cyprinids present and not known as a host species for this virus. The virus preferentially replicated in cultures of the epithelioma papulosum cyprini cell line where focal plaques of infection developed slowly. Examination of infected cell cultures by electron microscopy revealed non-enveloped 60 to 70 nm icosahedral virions that had characteristic multiple segregated protrusions of their outer capsid. A partial RNA-dependent RNA polymerase gene sequence was obtained and a BLAST search indicated 76% identity to golden shiner reovirus and grass carp reovirus. These results suggested that the virus belonged to the genus Aquareovirus (Family Reoviridae). Phylogenetic analysis placed the isolated virus within a clade of the species Aquareovirus C species. Accordingly, the virus was tentatively designated as white bream reovirus (WBRV) strain A-127/06 within the species Aquareovirus C.

Abstract
Toll-like receptors (TLRs) are expressed by immune cells, intestinal epithelium, and tumor cells. In the homeostatic setting, they help to regulate control over invading pathogens and maintain the epithelial lining of the large and small intestines. Aberrant expression of certain TLRs by tumor cells can induce growth inhibition while others contribute to tumorigenesis and progression. Activation of these TLRs can induce inflammation, tumor cell proliferation, immune evasion, local invasion, and distant metastasis. These TLR-influenced behaviors have similarities with properties observed in leukocytes, suggesting that tumors may be hijacking immune programs to become more aggressive. The concept of epithelial to leucocytic-transition (ELT) is proposed, akin to epithelial to mesenchymal transition, in which tumors develop the ability to activate leucocytic traits otherwise inaccessible to epithelial cells. Understanding the mechanisms of ELT could lead to novel therapeutic strategies for inhibiting tumor metastasis.

Abstract
Abstract
Background: Programmed death ligand 1 (PDL1) is commonly expressed on the surface of many tumor cells, including breast cancer. The activity of tumor infiltrating lymphocytes (TIL) is inhibited by PDL1. Blocking PDL1 with monoclonal antibodies can prevent this immune suppression and enhance anti-tumor activity. Polyinosinic-polycytidylic acid (Poly I:C) is a Toll like receptor 3 (TLR3) agonist which was shown to synergize with anti-PDL1 antibodies in a B16 melanoma model (Celis et. al, Blood 2010). We sought to investigate if synergy could be demonstrated in a murine breast cancer model.
Methods: Five week old female BALB/c mice were injected with 3x106 4T1 cells in a mammary fat pad and divided into 4 groups with ten mice/group (PBS control, 200µg anti-PDL1 antibody (10F.9G2 Bioxcell) D1,5 IP, 50µg Poly I:C (Invivogen) D1,6,11,16 IV, anti-PDL1+Poly I:C). Treatment started when tumors were palpable and measured twice weekly. The mice were sacrificed 20 days later with tumors, spleens, and lymph nodes harvested. Tumors were measured twice weekly. All experiments were carried out under approved IACUC #4277R per institutional guidelines. Statistical analysis performed using Prism Graphpad.
Results: Mean tumor measurements (mm2) at day 20 for control=207.5, anti-PDL1=188.5, Poly I:C=182.6, anti-PDL1+Poly I:C=149.4. Two way ANOVA was statistically significant at p<.0001. Mean tumor weight (gm) at day 20 of anti-PDL1+Poly I:C=.99 vs control=1.23 p=.002 using t test.
Conclusions: The combination of anti-PDL1 and Poly I:C TLR3 agonist demonstrates improved anti-tumor activity against established 4T1 orthotopic murine breast tumors compared to control or either agent alone. Characterization of TIL infiltrates in tumor specimens and immune activation in harvested lymphocytes is ongoing and will be presented. This data provides preliminary evidence supporting continued investigation of the combination of PDL1 and Poly I:C immunotherapy for breast cancer.

Abstract
Proliferative kidney disease (PKD) is a widespread disease of farmed and wild salmonid populations in Europe and North America, caused by the myxozoan parasite Tetracapsuloides bryosalmonae. Limited studies have been performed on the epidemiological role in spread of the disease played by fish that survive infection with T. bryosalmonae. The aim of the present study was to evaluate the persistence of T. bryosalmonae developmental stages in chronically infected brown trout Salmo trutta up to 2 yr after initial exposure to laboratory-infected colonies of the parasite's alternate host, the bryozoan Fredericella sultana. Kidney, liver, spleen, intestine, brain, gills and blood were sampled 24, 52, 78 and 104 wk post-exposure (wpe) and tested for T. bryosalmonae by PCR and immunohistochemistry (IHC). Cohabitation trials with specific pathogen free (SPF) F. sultana colonies were conducted to test the viability of T. bryosalmonae. PCR detected T. bryosalmonae DNA in all tissue samples collected at the 4 time points. Developmental stages of T. bryosalmonae were demonstrated by IHC in most samples at the 4 time points. Cohabitation of SPF F. sultana with chronically infected brown trout resulted in successful transmission of T. bryosalmonae to the bryozoan. This study verified the persistence of T. bryosalmonae in chronically infected brown trout and their ability to infect the bryozoan F. sultana up to 104 wpe.

Abstract
AIMS We report the outcomes of a large lung stereotactic ablative body radiotherapy (SABR) programme for primary non-small cell lung cancer (NSCLC) and pulmonary metastases. The primary study aim was to identify factors predictive for local control. MATERIALS AND METHODS In total, 311 pulmonary tumours in 254 patients were treated between 2008 and 2011 with SABR using 48-60 Gy in four to five fractions. Local, regional and distant failure data were collected prospectively, whereas other end points were collected retrospectively. Potential clinical and dosimetric predictors of local control were evaluated using univariate and multivariate analyses. RESULTS Of the 311 tumours, 240 were NSCLC and 71 were other histologies. The 2 year local control rate was 96% in stage I NSCLC, 76% in colorectal cancer (CRC) metastases and 91% in non-lung/non-CRC metastases. Predictors of better local control on multivariate analysis were non-CRC tumours and a larger proportion of the planning target volume (PTV) receiving ≥100% of the prescribed dose (higher PTV V100). Among the 45 CRC metastases, a higher PTV V100 and previous chemotherapy predicted for better local control. CONCLUSIONS Lung SABR of 48-60 Gy/four to five fractions resulted in high local control rates for all tumours except CRC metastases. Covering more of the PTV with the prescription dose (a higher PTV V100) also resulted in superior local control.

Abstract
Cyprinid herpesvirus-3 causes high mortality rates in common and koi carp. siRNAs were designed to target thymidine kinase and DNA polymerase genes in vitro. siRNA targeting DNA polymerase gene was most effective at reducing viral release. The inhibition of viral replication by the siRNAs was quantitated by qPCR.
Cyprinid herpesvirus-3 (CyHV-3) is an etiological agent of a notifiable disease that causes high mortality rates affecting both the common and koi carp Cyprinus carpio L. There is no current treatment strategy to save CyHV-3 infected fish. RNA mediated interference (RNAi) is an emerging strategy used for understanding gene function and is a promising method in developing novel therapeutics and antiviral medications. For this study, the possibility of activating the RNAi pathway by the use of small interfering (si)RNAs was tested to inhibit in vitro viral replication of CyHV-3 in common carp brain (CCB) cells. The siRNAs were designed to target either thymidine kinase (TK) or DNA polymerase (DP) genes, which both code for transcripts involved in DNA replication. The inhibition of viral replication caused by the siRNAs was measured by a reporter gene, termed ORF81. Treatment with siRNA targeting either TK or DP genes reduced the release of viral particles from infected CCB cells. However, siRNA targeting DP was most effective at reducing viral release as measured by qPCR.

Abstract
Bovine herpes virus-1 (BoHV-1) is a serious viral pathogen of domestic and wild cattle. Herein, we report development of a new molecular diagnostic assay for rapid and sensitive detection of BoHV-1 utilizing the loop-mediated isothermal amplification (LAMP) technique. BoHV-1-LAMP assay was optimized to amplify the target DNA by incubation the Bst-DNA polymerase enzyme with a set of specially constructed six primers, based on the gE-gene of BoHV-1 virus, at 65°C for 60min. BoHV-1-LAMP products were detected by visual inspection using SYBR Green-I stain and had a ladder-like appearance by gel electrophoresis analysis. Negative results obtained with DNA from other tested fish viruses confirmed the specificity of the assay. The analytical sensitivity of the BoHV-1-LAMP assay was 1fg of BoHV-1 DNA (dilution of 10(6)). The developed assay could successfully detect BoVH-1 DNA from clinical samples. Results of this study indicate that the developed BoHV-1-LAMP is rapid and highly sensitive assay not only for detection of BoHV-1 in clinical samples, but also for differentiation between wild-type (gE-positive) and gE-negative BoHV-1 viruses, which will improve the control programs of BoHV-1 in Egypt.

Abstract
BACKGROUND Tumor cells express programmed death ligand 1 (PD-L1) and is a key immune evasion mechanism. PD-L1 expression in multiple breast cancer cell lines was evaluated to identify intrinsic differences that affect their potential for immune evasion. METHODS PD-L1 expression was analyzed in six breast cancer cell lines: AU565&MCF7 (luminal), BT20&HCC1143 (basal A), MDA231&HCC38 (basal B). Surface and intracellular PD-L1 expression +/- interferon γ for 48 hours was measured by flow cytometry. PD-L1 gene expression data for all breast cancer cell lines in the Comprehensive Cell Line Encyclopedia (CCLE) was analyzed. Correlation between PD-L1 levels and clinicopathologic parameters was analyzed within Oncomine datasets. A tissue microarray containing 61 invasive breast cancer primary tumor cores was stained for PD-L1 expression and analyzed. RESULTS Basal breast cancer cells constitutively express the highest levels of PD-L1. All cell lines increased PD-L1 expression with interferon γ, but basal B cells (MDA-231 and HCC38) demonstrated the largest increases. There were no differences in protein localization between cell lines. In the CCLE data, basal cell lines demonstrated higher mean PD-L1 expression compared to luminal cell lines. High PD-L1 expressing basal cell lines over-express genes involved in invasion, proliferation, and chemoresistance compared to low PD-L1 basal cell lines. High PD-L1 basal cell lines had lower expression of IRF2BP2 and higher STAT1 levels compared to low PD-L1 expressing cell lines. Within Oncomine datasets PDL1 mRNA levels were higher in basal type tumors. The TMA analysis demonstrated that lymph node positive cases had higher levels of PD-L1 protein expression compared to lymph node negative cases. CONCLUSIONS Basal type breast cancer (especially basal B) express greater levels of PD-L1 constitutively and with IFN γ. High PD-L1 basal cells over-express genes involved in invasion, motility, and chemoresistance. Targeting PD-L1 may enhance eradication of aggressive breast cancer cells by the immune system.

Abstract
A full glycoprotein E (gE) deletion was generated in genome of the Egyptian BoHV-1.1 Abu-Hammad strain. Integrity of the gE negative (gE(-)) mutant virus was proved by successful specific PCR amplifications of gB, gC, tk, gD, gI and gE genes along with definite immune reaction to polyclonal anti-BoHV-1 antibody in infected cell culture. BoHV-1 gE(-) mutant exhibited growth kinetics inferior to those of the parental virus manifested as lower virus titers with delayed and poorer cytopathic effect in infected cells. Adjuvanted vaccines were made of the gE(-) mutant, live and killed; besides a conventional killed vaccine made of the parental virus and were used to immunize separate groups of calves. After i.m. vaccinations, no virus shedding could be detected in nasal swabs collected from all vaccinates and all calves remained apparently healthy. They all seroconverted to BoHV-1 as was revealed by virus neutralization test and a gB enzyme-linked immunosorbent assay (ELISA). Calves vaccinated with live and killed gE(-) vaccines did not elicit any detectable anti-gE antibody as shown by a blocking gE-ELISA. In conclusion, the constructed BoHV-1.1 gE(-) mutant was proved as safe and immunogenic as a reliable candidate for inclusion in a local marker vaccine.

Abstract
Cyprinid herpesvirus 3 (CyHV-3) is the aetiological agent of a serious and notifiable disease afflicting common and koi carp, Cyprinus carpio L., termed koi herpesvirus disease (KHVD). Significant progress has been achieved in the last 15 years, since the initial reports surfaced from Germany, USA and Israel of the CyHV-3 virus, in terms of pathology and detection. However, relatively few studies have been carried out in understanding viral replication and propagation. Antibody-based affinity has been used for detection of CyHV-3 in enzyme-linked immunosorbent assay and PCR-based techniques, and immunohistological assays have been used to describe a CyHV-3 membrane protein, termed ORF81. In this study, monoclonal antibodies linked to N-hydroxysuccinimide (NHS)-activated spin columns were used to purify CyHV-3 and host proteins from tissue samples originating in either CyHV-3 symptomatic or asymptomatic fish. The samples were next analysed either by polyacrylamide gel electrophoresis (PAGE) and subsequently by electrospray ionization coupled to mass spectrometry (ESI-MS) or by ESI-MS analysis directly after purification. A total of 78 host proteins and five CyHV-3 proteins were identified in the two analyses. These data can be used to develop novel control methods for CyHV-3, based on pathways or proteins identified in this study.

Abstract
Recently it has become clear that the cost associated with the Warburg effect, which is inefficient production of ATP, is offset by selective advantages that are produced by resultant intracellular metabolic alterations. In fact tumors may be addicted to the Warburg effect. In addition these alterations result in changes in the extracellular tumor microenvironment that can also produce selective advantages for tumor cell growth and survival. One such extracellular alteration is increased adenosine concentrations that have been shown to impair T cell mediated rejection and support angiogenesis. The expression of the A2A receptor in non-small cell cancer (NSCLC) tissues, cell lines and cancer associated fibroblasts (CAF) was determined by performing immunohistrochemistry and immunoblot analysis. The efficacy of the A2A receptor antagonists in vivo was evaluated in a PC9 xenograft model. To determine the mode of cell death induced by A2A receptor antagonists flow cytometry, immunoblot, and cytotoxic analysis were performed. We found that a significant number of lung adenocarcinomas express adenosine A2A receptors. Antagonism of these receptors impaired CAF and tumor cell growth in vitro and inhibited human tumor xenograft growth in mice. These observations add to the rationale for testing adenosine A2A receptor antagonists as anticancer therapeutics. Not only could there be prevention of negative signaling in T cells within the tumor microenvironment and inhibition of angiogenesis, but also an inhibitory effect on tumor-promoting, immunosuppressive CAFs and a direct inhibitory effect on the tumor cells themselves.

Abstract
BACKGROUND Advances have been made in the field of cancer immunotherapy in understanding the role of the host immune response in affecting tumor progression and response to various treatments. Through these advances, two novel immunotherapies were introduced in the clinic for melanoma and prostate cancer. METHODS This review discusses the available data regarding the immune-modulating effects of various treatments and how they can be utilized in the treatment of breast cancer. Databases including PubMed and Google Scholar were searched using terms including breast cancer, vaccines, and immunotherapy. RESULTS There is increasing evidence to support that certain breast tumors are intrinsically more immunogenic than others. Tumors that elicit more potent cytotoxic T-cell responses tend to have a more favorable prognosis and respond better to chemotherapy than less immunogenic tumors. Many standard treatments used in breast cancer rely in part on their immunogenic effects for their success in eradicating disease. Understanding how to use these agents to effectively augment the antitumor immune response may lead to better outcomes. Finally, many new immunomodulatory agents and vaccines that can reverse the immunosuppression caused by established tumors are in development. Combining these novel agents with current therapies may boost their efficacy. CONCLUSIONS Immunotherapeutic approaches combined with novel sequences of chemotherapies, radiation, vaccines, and immunomodulating agents hold promise for enhancing the treatment of breast cancer.

Abstract
During April to June 2009 and February 2010 to February 2011, numerous digenetic trematode metacercariae were observed embedded in the muscles of guppies Poecilia reticulata cultured at Kidchakan Supamattaya Aquatic Animal Health Research Center, Songkhla, southern Thailand. A total of 424 guppies were examined to identify the parasite and to study its pathogenicity. Based on conventional parasitological techniques, the parasitic digenean found in the guppies was identified as Euclinostomum heterostomum Rudolphi, 1809. Histological analysis revealed numerous metacercariae embedded in the fish muscle. A life cycle study indicated that the snail Indoplanorbis exustus was the first intermediate host, with the guppies serving as the second intermediate host. No E. heterostomum metacercariae were found in cohabited fish species, giant sailfin molly Poecilia velifera or platy Xiphophorus maculatus, which indicated that the guppy was the only suitable fish host present.

Abstract
Abstract
Background
The molecular subtypes of breast cancer described by Charles Perou provides greater insight into the underlying biology of different breast cancers. An important aspect of this biology is the ability of a particular breast cancer to evade the host immune response through activation of immunosuppressive pathways. Understanding the relationship between molecular subtypes and potential for immune evasion is important in determining which breast tumors can be targeted by immunomodulatory treatments. We focused specifically on the surface expression of the programmed death ligand 1 (PDL1) on breast cancer cell lines within different molecular subtypes. Binding of PD1 on T cells by its ligand PDL1 causes an inhibitory cascade resulting in T cell anergy and apoptosis. Expression of PDL1 on tumor cells creates an immunosuppressive environment reducing the number of tumor specific cytotoxic T cells. A potent inducer of PDL1 expression is interferon γ (IFN γ), which is frequently present in the tumor microenvironment. We sought to study differences in PDL1 expression between luminal (MCF7, AU565), basal A (BT20, HCC1143), and basal B (MDA231, HCC38) breast cancer cell lines provided by CK Zhang at ATCC.
Methods
PDL1 protein expression was analyzed in an ATCC assay ready breast cancer cell panel. Surface and intracellular PDL1 expression +/- IFN γ for 48hrs was measured by flow cytometry (BD Biosciences) on a LSRII with mean fluorescence intensity (MFI). The cells were treated with 50 μM of epigallocatechin gallate (EGCG) (Sigma), a STAT1 inhibitor, to explore the role of STAT1 signaling in the expression of PDL1. Levels of intracellular phosphoSTAT1 were also measured by flow (Beckman Coulter) in these experiments.
Results
Basal cells had the greatest baseline MFI values (mean 1817) vs luminal (mean 0). All cells increased PDL1 expression with IFN γ, but the basal B cells demonstrated the largest absolute increases by far (HCC38 MFI =13948 vs. MCF7 MFI =764). This was in part due to greater total PDL1 expression, but also a larger proportion of total expressed PDL1 localizing to the surface in comparison to the other molecular subtypes. Finally, treatment with EGCG was able to significantly inhibit expression of PDL1 and lowered levels of pSTAT1 especially in the HCC38 cell lines.
Conclusion
Our data suggests that basal type breast cancer cells (especially basal B) express greater levels of PDL1 both constitutively and in response to IFN γ. It appears that the STAT1 pathway is involved in mediating this effect in response to IFN γ. Prospective knowledge of a breast tumor's ability to phenotypically express PDL1 based on molecular subtype will allow for better selection of patients for future anti-PDL1 antibody clinical trials.

Abstract
Papillary renal-cell carcinoma (pRCC) is unusual for its occurrence in kidneys with chronic dysfunction, for its frequent multifocality and for its common association with papillary adenoma, a benign renal lesion morphologically indistinguishable from pRCC. Concomitant development of papillary adenoma and pRCC in five transplanted kidneys, where donor and recipient characteristics are well established, provided a unique opportunity for molecular studies of de novo pRCC carcinogenesis. We aimed to study this tumor type to determine whether or not the different papillary tumors have the same origin, and whether or not papillary adenomas are precursor lesions of pRCC. We performed XY-FISH in sex-mismatched kidney transplants, and polymorphic microsatellite DNA and high-resolution melting of mitochondrial DNA analyzes in all five patients on laser-microdissected tumor cells, then compared these molecular profiles to donor and recipient profiles. This study (i) identified the recipient origin of de novo papillary adenomas and pRCCs in a kidney transplant, (ii) demonstrated an identical origin for precursor cells of papillary adenomas and pRCCs and (iii) showed additional genetic alterations in pRCCs compared to papillary adenomas. This molecular approach of papillary tumors developed in transplanted kidney identified successive steps in carcinogenesis of human de novo papillary renal-cell carcinoma.

Abstract
The freshwater bryozoan Fredericella sultana (Blumenbach) is the most common invertebrate host of the myxozoan parasite Tetracapsuloides bryosalmonae, the causative agent of proliferative kidney disease in salmonid fish. Culture media play an important role in hatching of statoblasts and maintaining clean bryozoan colonies for Malacosporea research. We developed a novel culture medium, Bryozoan Medium C (BMC), for the cultivation and maintenance of F. sultana under laboratory conditions. Statoblasts of F. sultana were successfully hatched to produce transparent-walled, specific pathogen-free (SPF) colonies that were maintained >12 months in BMC at pH 6.65. Tetracapsuloides bryosalmonae was successfully transmitted from infected brown trout, Salmo trutta L., to newly hatched F. sultana colonies in BMC, then from the infected bryozoan to SPF brown trout. This study demonstrated the utility of BMC (pH 6.65) for hatching statoblasts, long-term cultivation of clean and transparent bryozoan colonies and maintenance of the Tetracapsuloides bryosalmonae life cycle in the laboratory for molecular genetic research and other studies such as host-parasiteinteraction.

Abstract
INTRODUCTION The immunosuppressive enzyme, indoleamine 2,3 dioxygenase (IDO), is overexpressed in many different tumor types including breast cancer. IDO inhibitors synergize with chemotherapy in breast cancer murine models. Characterizing IDO expression in breast cancer could define which patients receive IDO inhibitors. This study analyzed IDO protein expression in 203 breast cancer cases. The relationship between IDO, overall survival (OS), disease-specific survival (DSS), clinicopathologic, molecular, and immune tumor infiltrate factors was evaluated. METHODS Expression of IDO, estrogen receptor (ER), progesterone receptor (PR), human epithelial receptor 2, cytokeratin 5/6, epithelial growth factor receptor, phosphorylated AKT, neoangiogenesis, nitrogen oxide synthetase 2 (NOS2), cyclooxygenase 2 (COX2), FoxP3, CD8, and CD11b on archival breast cancer tissue sections was evaluated by immunohistochemistry. Associations between IDO and these markers were explored by a univariate and multivariate analysis. Survival was analyzed using Kaplan-Meier (OS) and Wilcoxon two-sample (DSS) tests. RESULTS IDO expression was higher in ER+ tumors compared to ER- tumors. IDO was lower in those with higher neoangiogenesis. OS was better in ER+ patients with high IDO expression. DSS was better in node-positive patients with high IDO expression. IDO activity positively correlates with NOS2. COX2 as positively correlated with IDO on univariate but not multivariate analysis. There was a trend toward greater numbers of CD11b+ cells in IDO-low tumors. CONCLUSIONS IDO protein expression is lower in ER- breast tumors with greater neoangiogenesis. Future clinical trials evaluating the synergy between IDO inhibitors and chemotherapy should take this finding into account and stratify for ER status in the trial design.

Abstract
Abstract
Background: Gene expression profiling in breast cancer offers the potential to improve prognostic accuracy, treatment choice, and health outcomes in women diagnosed with early-stage breast cancer. Numerous gene-profiling assays are now available, which can be applied to a single tumor specimen to provide physicians with a more complete basis for treatment decisions.
MammaPrint is a DNA microarray-based in vitro diagnostic that measures the activity of 70 genes to estimate whether patients are at high risk or low risk of developing metastases within the first 10 years after curative surgery. BluePrint is an 80-gene molecular subtyping profile that discriminates between three breast cancer subtypes: Luminal, HER2, and Basal. TargetPrint provides a quantitative measurement of estrogen receptor (ER), progesterone receptor (PR), and HER2, and can serve as a reliable second pathology assessment for locally-assessed parameters. Oncotype DX measures expression of five reference genes and 16 cancer-related genes, quantifying the risk of distant recurrence in patients with ER+ early breast cancer who are treated with adjuvant hormonal therapy, and predicting clinical benefit with additional adjuvant chemotherapy.
Trial design: PROMIS is a prospective, observational, case-only study that will investigate the additional value of MammaPrint, BluePrint and TargetPrint in women with an intermediate Oncotype DX score. An initial CRF – capturing baseline patient characteristics, pathology information, Oncotype DX score and the recommended treatment plan – will be completed before receiving the MammaPrint result. A second CRF – capturing the recommended treatment – will be completed within 4 weeks after receiving the MammaPrint result.
Eligibility: The study will include women aged ≥18 years with histologically proven invasive stage I-II, node-negative, hormone receptor-positive, HER2-negative breast cancer and Oncotype DX score of 18–30 who signed informed consent.
Objectives: The objectives of the study are to: 1. Describe the frequency of chemotherapy + endocrine versus endocrine-alone decisions in Oncotype DX intermediate score patients.2. Assess the impact of MammaPrint on chemotherapy + endocrine versus endocrine-alone treatment decisions.3. Assess the distribution of MammaPrint Low and High Risk in patients with an intermediate recurrence score.4. Assess concordance of TargetPrint ER, PR and HER2 results with Oncotype DX ER, PR and HER2 and with locally assessed IHC/FISH ER, PR and HER2.5. Compare clinical subtype based on IHC/FISH ER, PR, HER2 and Ki-67 (if available) with BluePrint molecular subtype.
Statistical methods: As the project is exploratory, sample size calculations do not apply as only descriptive statistics will be used. The frequency of chemotherapy + endocrine versus endocrine-alone decisions in Oncotype DX intermediate score patients will be calculated before and after receiving the MammaPrint result. A Chi-square test will be performed for the comparison of the two proportions.
Accrual: A total of ∼300 eligible patients will be enrolled from multiple institutions.

Abstract
Our objective was to evaluate diagnostic tools for the detection of Inclusion Body Disease (IBD) in bold snakes. The aetiology of IBD is unknown, and the disease has non-specific clinical signs, hence there is a need for a clinically-applicable, specific diagnostic method. We examined blood smears and liver biopsies from 26 bold snakes (17 boas and nine pythons; some of which were suspected of having IBD) for the presence of characteristic inclusion bodies. We used haematology, histology and electron microscopy to characterise samples as IBD-positive or -negative. Our results indicate that examination of a simple blood smear is sufficient to diagnose IBD in boas. Inclusion bodies in lymphocytes, erythrocytes and thrombocytes were observed. In both, boas and pythons, we detected inclusion bodies within hepatocytes. We demonstrated also that IBD was more common in boas than in pythons: only samples from two Ball Pythons (Python regius) tested positive, whereas no other Pythonidae were positive. We consider that blood smears represents a rapid, non-invasive technique for detection of IBD.

Abstract
Spring viraemia of carp (SVC) is a viral disease that mainly affects carp Cyprinus carpio and other cyprinid fish, causing severe economic losses. Rapid detection and identification of spring viraemia of carp virus (SVCV) is crucial for effective disease management. Recent advances in nanoscience are having a significant impact on many scientific fields, especially biodiagnostics, where a number of nanoparticle-based assays have been introduced for biomolecular detection. Single- and double-stranded oligonucleotides can be adsorbed on gold nanoparticles (AuNPs) in colloidal solution under certain conditions. We exploited this phenomenon to develop a specific hybridization assay for direct detection of SVCV-RNA without prior amplification. The result of the hybridization process could be detected visually within 1 min when the colour of the reaction mixture changed from red to blue (positive reaction) or remains red (negative). The lower detection limit of the assay was estimated to be 10-3 TCID50 ml-1 SVCV-RNA, and it has the feasibility to detect the target virus-RNA in clinical specimens without previous amplification. In order to obtain an indication of the assay's performance on clinical samples we compared the optimized assay with nested RT-PCR in detection of SVCV-RNA in infected fish samples. The concordance of the 2 methods was defined as 100% when compared to nested RT-PCR positive and negative samples. The SVC-AuNPs assay requires only 15 min, eliminates the need for thermal cycling or detection instruments and is a specific and rapid tool for detection of SVCV-RNA directly from clinical samples.

Abstract
BACKGROUND Although there is an extensive body of literature on the role of neoadjuvant chemoradiotherapy (CRT) in the management of rectal cancer, its role in primary locally advanced adherent colon cancer (LAACC) is unclear. OBJECTIVE To analyzed the outcomes of neoadjuvant CRT and multivisceral resection in the management of LAACC patietns. METHODS We retrospectively reviewed our institutional Colorectal Carcinoma Database for 33 patients with potentially resectable, non-metastatic primary LAACC who received neoadjuvant CRT followed by multivisceral resection. CRT consisted of external beam radiation (45-50 Gy in 25 daily fractions) and concurrent 5-FU infusion (225 mg/m(2)/day). RESULTS There were 21 males and 12 females. Median age was 64 (31-83) and median follow-up was 36 months. All patients had microscopically clear resection margins (R0). Complete pathologic response was documented in 1 patient (3%) and 66% had ypT4b disease. Post-operative complications were observed in 36% of patients with no 30-day mortality. The 3-year overall survival and 3-year disease-free survival were 85.9% and 73.7% respectively. Two patients developed a local recurrence. CONCLUSIONS Neoadjuvant CRT and en-bloc multivisceral resection may result in high rates of R0 resection and excellent local control with acceptable morbidity and mortality in selected patients with LAACC.
