Lymphoepithelioma-like carcinoma (LELC) of the lung is a rare Epstein-Barr virus (EBV)-associated carcinoma. It is histologically characterized by a syncytial growth pattern with marked lymphocytic infiltration that is indistinguishable from the histology observed in undifferentiated nasopharyngeal carcinomas. However, it has been noted that LELC can display nonclassic morphology and lack significant lymphocytic infiltration. In this study, we conducted a comprehensive clinicopathologic analysis of 61 patients with pulmonary LELC and performed automatic quantification of the lymphocytic infiltrate using the IHC Profiler software...

Infection of immunocompromised individuals with normally benign opportunistic viruses is a major health burden globally. Infections with viruses such as Epstein-Barr virus (EBV), human cytomegalovirus (HCMV), Kaposi's sarcoma virus (KSHV), adenoviruses (AdV), BK virus (BKPyV), John Cunningham virus (JCPyV), and human papillomavirus (HPV) are significant concerns for the immunocompromised, including when these viruses exist as a co-infection with human immunodeficiency virus (HIV). These viral infections are more complicated in patients with a weakened immune system, and often manifest as malignancies resulting in significant morbidity and mortality...

Natural killer/T-cell lymphoma (NKTL) is a rare subtype of non-Hodgkin's lymphoma that is associated with Epstein-Barr virus infection. The clinicopathological features of NKTL are unique among lymphomas. NKTL is an aggressive disease with a poor prognosis in the absence of effective treatment. Accurate diagnosis and staging are essential to ensure an appropriate treatment strategy and accurate prognosis of NKTL. 18 F-Fluorodexoyglucose-positron emission tomography/computed tomography (18 F-FDG PET/CT) is a valuable technique in the diagnosis, staging, and prognostic evaluation of various types of malignant tumors, including NKTL...

BACKGROUND: Sepsis is a common cause of hospitalization, particularly in intensive care units (ICUs), and is a major cause of morbidity and mortality. Diagnosis is often difficult due to the absence of characteristic clinical signs (e.g., fever and leukocytosis); therefore, additional markers, in addition to C-reactive protein (CRP) and white blood cell (WBC) count, are needed. OBJECTIVES: To prospectively link resting energy expenditure (REE) with CRP, WBC count, and sequential organ failure assessment (SOFA) scores in ICU patients...

Objectives: Infections are a major cause of mortality after allogeneic haemopoietic stem cell transplantation (alloHSCT), and immune recovery is necessary for prevention. Novel transplant procedures have changed the epidemiology of infections but contemporary data on functional immune recovery are limited. In this pilot study, we aimed to measure immune recovery in the current era of alloHSCT. Methods: Twenty, 13, 11, 9 and 9 alloHSCT recipients had blood collected at baseline (time of conditioning) and 3-, 6-, 9-, and 12-months post-alloHSCT, respectively...

Gastric and esopahgeal cancers account for the six most common causes of cancer death worldwide. Locally advanced resectable cancers have a 5-year life expectancy of 30%. Despite use of chemotherapy, median overall survival for stage IV cancer rarely exceeds 1 year. A subset of gastric cancers such as microsatellite-instable tumor and Epstein-Barr virus-positive tumors have a rich immune infiltrate that makes them more responsive to immune-directed therapies. Tumors can evade T-cell-mediated "immune surveillance" by activating the programmed cell death receptor 1 (PD-1)/programmed death ligand 1 (PD-L1) pathway...

Addiction treatment has not been appreciably improved by neuroscientific research. One problem is that mechanistic studies using rodent models do not incorporate volitional social factors, which play a critical role in human addiction. Here, using rats, we introduce an operant model of choice between drugs and social interaction. Independent of sex, drug class, drug dose, training conditions, abstinence duration, social housing, or addiction score in Diagnostic & Statistical Manual IV-based and intermittent access models, operant social reward prevented drug self-administration...

A 50-year-old woman developed recurrent vitreous opacities in her left eye. The first diagnostic vitrectomy revealed no significant abnormality. OCT showed multiple high-density reflective nodules. The ratio of Interleukin 6 to 10 was over 1 in her aqueous humor, and Epstein-Barr virus was present. Conventional immunohistochemistry examination of vitrectomy specimens was diffusely positive for CD2, CD3, Ki67. Highly-metabolic nodules were found in her right breast on PET-CT scan. Immunohistochemistry of the breast biopsy was suggestive of NK/T cell lymphoma...

A key requirement for femtosecond spectroscopy measurements is to compress the laser pulse to its transform-limited duration. In particular, for few-cycle laser pulses, the compression process is time-consuming using conventional algorithms that converge statistically. Here we show that machine learning can accelerate the process of pulse compression: we have developed an adaptive neural-network algorithm to control a deformable-mirror-based pulse shaper that converges 100× faster than a standard evolutionary algorithm...

Iatrogenic lymphoproliferative disorders have been described in patients receiving immunosuppressive/immunomodulatory agents outside the transplantation setting. Novel biological agents such as TNF-α blockers and JAK-inhibitors have also proven to be effective in many disorders including rheumatoid arthritis, inflammatory bowel disease (ulcerative colitis and Crohn disease), psoriasis, and others. A significant dilemma exists in those lymphoproliferative disorders associated with immunosuppressants and rheumatologic conditions, that relies on whether the association of the process is with the medication or the underlying autoimmune condition...

Interleukin (IL)-35 is a heterodimeric cytokine composed of the IL-12A subunit and the Epstein-Barr virus induced gene 3 (EBI3) subunit. Binding of IL-35 with IL-12 receptor subunit beta 2 (IL-12RB2) and IL-6 signal transducer (IL-6ST) occupies the binding sites of IL-6, IL-12, and IL-27 and prevents their signal transduction. IL-35 is also shown to promote the development of regulatory T cells (Tregs) and regulatory B cells (Bregs). In this study, we investigated B cell-mediated IL-35 production in patients with coronary artery disease (CAD)...

Immunological parameters that influence susceptibility to virus-associated cancers in HIV-seronegative individuals are unclear. We conducted a case-control cohort study of immunological parameters associated with development of incident virus-associated cancers among 532 HIV-seronegative men who have sex with men (MSM) enrolled in the Multicenter AIDS Cohort Study (MACS) with median (IQR) 21 (8-26) years of follow-up. Thirty-two incident virus-associated cancers (anal cancer, non-Hodgkin lymphoma, liver cancer, other cancers with etiologies linked to human papillomavirus, Epstein-Barr virus, hepatitis B virus, or human herpesvirus-8) were identified among 3,408 HIV-seronegative men in the MACS during 1984-2010...

The North American monarch butterfly ( Danaus plexippus ) population has declined significantly over the past two decades. Among the many other factors, loss of breeding habitat has been implicated as a potential leading driver. In response, wildlife agencies and conservation practitioners have made a strong push to restore and conserve milkweeds on both wild and managed landscapes including agricultural lands as well as transportation and utility rights-of-way. Roadsides in particular have been emphasized as a targeted landscape for monarch habitat restoration...

Background: The EBV viral glycoprotein gp350 has been proposed as a candidate antigen for an EBV vaccine. However, the proposed formulations of these vaccines have not taken into account the presence of two unique EBV strains (EBV-1 and EBV-2) present in areas of high incidence of the EBV associated cancer, Burkitt's lymphoma. Methods: In this study, we analyze the kinetics of EBV-1 and EBV-2 infection in an asymptomatic infant cohort from Kisumu, Kenya. We also analyzed the kinetics of the antibody response against five EBV antigens, gp350 (IgG and IgA), VCA (IgG), EBNA-1 (IgG), EAd (IgG), and Zta (IgG)...
