    Abstract Studying the process of producing scientific articles in any field of knowledge can provide a clear picture of the scientific trajectory of a journal and identify research gaps in that area. Meantime, reviewing the published researches in tourism studies can provide a correct understanding of theoretical approaches, methods, and techniques used by researchers. Moreover, it indicates how theoretical development and methodological progress can provide documentary information. It presents the evolution and process of conducting these researches over a specific period of time; yet it can provide clear vision of limitations, harms, and issues that need more attention from researchers, as well as managers and planners in this field. The purpose of this study is to review scientific articles published in the journal "Tourism Management Studies" based on four components: characteristics, pattern of participation of authors and methodological, citation, and functional characteristics of articles. The research method is descriptive, and the content analysis method has been used specifically. The collection of information is in the form of libraries and the method of their analysis is quantitative. Samples are 219 articles (N = 219), including all articles published in Tourism Management Studies journal, during 2012-2018, in 8 periods and 32 issues (17-48). Study result has revealed a clear picture of authors' participatory patterns, as well as the methodological, functional and citation features of articles. It also describes the trajectory and trend of stability or changes in each of the patterns and features studied during eight years of this journal.

    Abstract Background: Peripheral T-cell neoplasms (PTCNs) comprise a group of uncommon and heterogeneous lymphoid malignancies. They are more difficult to diagnose and treat and have a worse prognosis than B-cell lymphomas. Although PTCNs initially show a significant degree of chemosensitivity, the outcome of treatment with conventional dose chemotherapy remains poor.
    Methods: We reviewed the literature on the diagnosis, treatment, and collective transplant reports regarding PTCNs.
    Results: The correct diagnosis of peripheral T-cell lymphoma requires a combination of clinical presentation, morphology, immunophenotype, and molecular study. While no specific treatment other than conventional dose chemotherapy is currently available for aggressive PTCN, histone acetylase inhibitors and monoclonal antibodies such as anti-CD7 and anti-CD52 are being studied in T-cell malignancies. The role of autologous and allogeneic transplantation is being investigated for high-risk, relapsed, and refractory PTCNs with some promising results.
    Conclusions: Access to hematopathology expertise in a tertiary care setting may lead to earlier and more accurate diagnoses of these diseases. PTCNs comprise a heterogeneous group of diseases with no widely accepted standard of care, and accurate determination of their histologic subtypes correlates with prognosis. Patients in first complete remission with poor risk features and patients with relapsed and refractory disease should be considered for bone marrow transplant due to the poor outcomes obtained with conventional chemotherapy.

    Abstract Background: The classification of cutaneous lymphomas has been contentious. Two major competing classifications were the World Health Organization (WHO) and the European Organization for Research and Treatment of Cancer (EORTC). The principal authors met for a consensus meeting resulted in a combined classification called WHO-EORTC Classification of Cutaneous Lymphoma.
    Methods: We review the classification of "mature" or peripheral T-cell lymphoma (PTCL) with high predilection to the skin as published by the WHO-EORTC. We also highlight new information and changes from the previous classifications of cutaneous PTCL according to the WHO classification or the EORTC classification. Finally, the salient findings are compared with similar-looking nodal PTCLs with a high frequency of skin involvement.
    Results: This review focuses on a rare group of cutaneous PTCLs other than mycosis fungoides or its variants. Changes from the previous classifications are discussed, and the rare group of nodal PTCLs with high predilection to the skin are presented. The salient findings, diagnostic features, and treatments are included, along with summary tables and clinical-histopathologic images.
    Conclusions: This review may serve as a guide for hematologists, oncologists and dermatologists in the diagnosis and management of these rare, aggressive, and often difficult to diagnose lymphomas. Although cutaneous lymphomas are morphologically identical to systemic lymphomas, the former behave differently, require divergent management, and should be recognized as separate entities. The consensus WHO-EORTC classification presents unified terminology and definitions to promote conformity in diagnosing and treating these cases, to foster a multidisciplinary approach to these often-obscure diseases, and to lead to more advances in identifying molecular targets specific to these entities.

    Abstract The association between cytomegalovirus infection and inflammatory bowel disease challenges both the clinician and the pathologist to establish the correct diagnosis and to prescribe the most appropriate form of therapy. To understand this association the authors report three patients who presented with signs and symptoms mimicking reactivated inflammatory bowel disease who responded poorly to aggressive treatment of inflammatory bowel disease. Microscopic examination, in all three cases revealed numerous nuclear and cytoplasmic viral inclusions, as demonstrated by cytomegalovirus immunohistochemistry, as well as histologic findings consistent with inflammatory bowel disease (ulcerative colitis and/or Crohn's disease). Because the clinical pathologic features of cytomegalovirus colitis and inflammatory bowel disease often overlap, and because of the possible coexistence of cytomegalovirus colitis with idiopathic colitis, the possibility of cytomegalovirus infection should be always considered, so that the most appropriate therapy can be instituted for these patients.

    Abstract Primary cutaneous B-cell lymphoma is a B-cell lymphoma of the skin with no evidence of extracutaneous involvement at the time of diagnosis. In this report, we describe an 8-year-old boy who presented with a firm, alopecic, skin-colored, smooth nodule over the right frontal scalp. Histological examination revealed a mid-to deep-dermal mononuclear lesion. Immunohistochemical staining revealed a B-cell population that was CD10(+), CD5(-), CD21(+), and bcl2(-). This pattern of reactivity is characteristic of primary cutaneous B-cell lymphoma of follicle-center subtype. To the best of our knowledge, this is the first report of this type of cutaneous lymphoma in a child.

    Abstract Angioimmunoblastic T-cell lymphoma (AITL) is a systemic lymphoproliferative disease characterized by a polymorphous neoplastic infiltrate involving lymph nodes as well as extranodal locations, including the skin. Cutaneous involvement is seen in approximately 50 percent of cases and is usually secondary to systemic disease. Patients with cutaneous involvement classically present with a transient morbilliform eruption of the trunk; however, papules, nodules, urticarial plaques and erythroderma have also been reported. In contrast, primary cutaneous AITL is exceedingly rare. The authors report a case of a 79-year-old woman with AITL who presented with primary cutaneous tumors and ulcerated nodules, with no evidence of systemic involvement, hypergammaglobinemia, or B symptoms. Histologically, a subtle lymphoid infiltrate was present, dominated by marked fibrosis and a diffuse infiltrate of neutrophils, eosinophils and plasma cells, mimicking an inflammatory or infectious etiology. This presentation presents a unique diagnostic challenge; careful investigation and strong clinical suspicion must be utilized in order to correctly identify AITL in this setting.

    Abstract Mantle cell lymphoma (MCL) is one of the most aggressive B-cell lymphomas. Although several protein-coding genes are altered, expression signature and importance of microRNA (miRNA) have not been well documented in this malignancy. Here, we performed miRNA expression profile in 30 patients with MCL using a platform containing 515 human miRNAs. Eighteen miRNAs were down-regulated and 21 were up-regulated in MCL compared with normal B lymphocytes. The most frequently altered miRNAs are decrease of miR-29a/b/c, miR-142-3p/5p, and miR-150 and increase of miR-124a and miR-155. Notably, expression levels of miR-29 family are associated with prognosis. The patients with significant down-regulated miR-29 had short survival compared with those who express relatively high levels of miR-29. The prognostic value of miR-29 is comparable with the Mantle Cell Lymphoma International Prognostic Index. Furthermore, we demonstrate miR-29 inhibition of CDK6 protein and mRNA levels by direct binding to 3'-untranslated region. Inverse correlation between miR-29 and CDK6 was observed in MCL. Because cyclin D1 overexpression is a primary event and exerts its function through activation of CDK4/CDK6, our results in primary MCL cells indicate that down-regulation of miR-29 could cooperate with cyclin D1 in MCL pathogenesis. Thus, our findings provide not only miRNA expression signature but also a novel prognostic marker and pathogenetic factor for this malignancy.

    Abstract Molecular adlayers on mica have been visualized previously by coating the sample with graphene and imaging it by scanning force microscopy. While it had been argued that this shows that ambient water on mica exhibits ice-like structures, recent apparently similar experiments indicate different behaviors. Here, we demonstrate that adhesive tapes, which are often used to mechanically exfoliate graphenes onto solid substrates, can lead to water-containing adlayers, which differ substantially from pure water layers. We exfoliated graphenes with the aid of different adhesive tapes and demonstrate that the results depend on the particular tape. Our results imply that structure and properties of confined water adlayers can be controlled by minor amounts of additives.
