1. Follicular mucinosis - Case report
Follicular mucinosis, also known as alopecia mucinosa, is a cutaneous mucinosis histologically characterized by accumulation of dermal type mucin in the pilosebaceous follicle and sebaceous glands. It presents in two forms, a primary or idiopathic form and a secondary form associated with various benign or malignant processes. Among the malignant processes,

2. Adhesion molecule profiles of B-cell non-Hodgkin's lymphomas in the leukemic phase
We evaluated the expression of 10 adhesion molecules on peripheral blood tumor cells of 17 patients with chronic lymphocytic leukemia, 17 with mantle-cell lymphoma, and 13 with nodal or splenic marginal B-cell lymphoma, all in the leukemic phase and before the beginning of any therapy. The diagnosis of B-cell non-Hodgkin's lymphomas was based on cytological,

3. FMNL1 : caracterização de um novo gene humano relacionado com a familia das forminas
Formins are proteins that are involved in processes such as morphogenesis, embryonic differentiation, cytokinesis, cell polarity and survival. The formins are multidomain proteins that are conserved from plants to fungi and vertebrates. A search of the ORESTES database, generated from the Human Cancer Genome Project, identified 2 ESTs that were similar to th

4. ROLE OF Bcl-2 AND Bcl-XL IN ANGIOGENESIS
(...)Angiogenesis is defined as the development of new capillaries from pre-existing blood vessels. The hypothesis that tumor growth is angiogenesis dependent was proposed by Judah Folkman in 1971, and it has been confirmed by many investigators thereafter. We have shown that vascular endothelial growth factor (VEGF) induces Bcl-2 expression in endothelial c

5. Soroprevalencia e epidemiologia molecular do herpesvirus humano 8 (HHV-8) em populações brasileiras
CHANG et al first identified human Herpesvirus Type 8 (HHV-8) in 1994 from skin biopsies of patients with Acquired Immunodeficiency Syndrome (AIDS) associated Kaposi?s Sarcoma (KS). HHV-8 is an oncovirus from the Herpesviridae family, Gamaherpesvirinae subfamily and Rhadinovirus genus. It is the only one of its genus to infect humans. Its ultra structure rem

6. Polimorfismo genético da quimiocina SDF-1 humana e expressão do RNA mensageiro do seu receptor CXCR4 em leucemia e linfoma
O SDF-1 (fator derivado do estroma da medula óssea), também conhecido como CXCL12, e seu receptor CXCR4 estão envolvidos no tráfego de células B e progenitores hematopoéticos. A medula óssea produz o SDF-1, o qual possui atividade marcante de quimiotaxia através da ligação com seu receptor CXCR4 acoplado a proteína G, em um complexo que envolve 7

7. Oral lymphomas: reclassification and characterization of the dendritic cell / "Linfomas de boca: reclassificação e caracterização das células dendríticas"
Oral lymphomas: reclassification and characterization of the dendritic cell The aim of this study was to evaluate and reclassificate oral lymphomas in accordance with WHO-2001. Forty-six oral lymphomas were included in the study. Clinical data, hematoxylin and eosin patterns were considered. The tumors were then submitted to immunohistochemical for unophenot

8. Rare Anorectal Neoplasms: Gastrointestinal Stromal Tumor, Carcinoid, and Lymphoma
Several uncommon tumors occur in the anal canal such as gastrointestinal stromal tumors, carcinoids, and lymphoma. Increased clinical experience and advancements in molecular biology have improved the accuracy of pathologic diagnosis and guided treatment recommendations, which the author addresses in this article.

9. Positron emission tomography provides molecular imaging of biological processes
Diseases are biological processes, and molecular imaging with positron emission tomography (PET) is sensitive to and informative of these processes. This is illustrated by detection of biological abnormalities in neurological disorders with no computed tomography or MRI anatomic changes, as well as even before symptoms are expressed. PET whole body imaging i

10. Spectrum of Kaposi's Sarcoma-Associated Herpesvirus, or Human Herpesvirus 8, Diseases
Human herpesvirus 8 (HHV-8), also known as Kaposi's sarcoma-associated herpesvirus (KSHV), discovered in 1994, is a human rhadinovirus (gamma-2 herpesvirus). Unlike other human herpesviruses (herpes simplex virus, Epstein-Barr virus, varicella-zoster virus, cytomegalovirus, HHV-6, and HHV-7), it is not widespread in the general population and has many unique

11. Status of Marek's disease virus in established lymphoma cell lines: herpesvirus integration is common.
Six cell lines derived from Marek's disease lymphomas of chickens and turkeys were investigated for the status of Marek's disease virus (MDV) DNA. In the transformed T- and B-cell lines, viral DNA could be detected by conventional Southern blot hybridization, by Gardella gel electrophoresis, and by in situ hybridization of metaphase and interphase chromosome
