1. Genetic-molecular characterization in the diagnosis of primary immunodeficiencies
Abstract Objectives: To rescue medical genetics concepts that are necessary to understand the advances in the genetic-molecular characterization of primary immunodeficiencies, to help in the understanding and adequate interpretation of their results. Source of data: Non-systematic literature review, searching for articles since 2000 on PubMed using the ter

2. Immunohistochemical analysis of S100-positive epidermal Langerhans cells in dermatofibroma,
Abstract Dermatofibroma is a dermal fibrohistiocytic neoplasm. The Langerhans cells are the immunocompetent cells of the epidermis, and they represent the first defense barrier of the immune system towards the environment. The objective was to immunohistologically compare the densities of S100-positive Langerhans cells in the healthy peritumoral epidermis ag

3. Isolamento e diferenciação das células-tronco da polpa dentária canina em células progenitoras neurais
RESUMO O objetivo deste estudo foi verificar a capacidade de diferenciação das células-tronco da polpa dentária canina em células progenitoras neurais bem como quantificar obtenção e viabilidade celular, durante três passagens em cultura. As células foram extraídas da polpa dentária de dois cadáveres caninos, com aproximadamente dez meses de idad

4. Complex karyotype including ring chromosome 11 in a patient with acute myeloid leukemia: case report
ABSTRACT CONTEXT: Complex karyotypes in acute myeloid leukemia (AML) are characterized by an overall low response rate with frequent relapses after clinical treatment. CASE REPORT: Here, we describe the case of a 61-year-old obese female with clinically diagnosed AML who presented a complex karyotype involving an uncommon abnormality: ring chromosome 11. I

5. Primary nodal peripheral T-cell lymphomas: diagnosis and therapeutic considerations
Nodal peripheral T-cell lymphomas are a rare group of neoplasms derived from post-thymic and activated T lymphocytes. A review of scientific articles listed in PubMed, Lilacs, and the Cochrane Library databases was performed using the term "peripheral T-cell lymphomas". According to the World Health Organization classification of hematopoietic tissue tumors,

6. Acute lymphoblastic leukemia in children and adolescents: prognostic factors and analysis of survival
OBJECTIVE: To describe the clinical and laboratory features of children and adolescents with acute lymphoblastic leukemia treated at three referral centers in Ceará and evaluate prognostic factors for survival, including age, gender, presenting white blood cell count, immunophenotype, DNA index and early response to treatment.METHODS: Seventy-six under 19-y

7. Brazilian minipig as a large-animal model for basic research and stem cell-based tissue engineering. Characterization and in vitro differentiation of bone marrow-derived mesenchymal stem cells
Stem cell-based regenerative medicine is one of the most intensively researched medical issues. Pre-clinical studies in a large-animal model, especially in swine or miniature pigs, are highly relevant to human applications. Mesenchymal stem cells (MSCs) have been isolated and expanded from different sources. Objective: This study aimed at isolating and char

8. Citomegalovírus, herpesvírus humano 6, herpesvírus humano 7 e perfil imunofenotípico do infiltrado inflamatório na periodontite crônica marginal / Cytomegalovirus, human herpesvirus 6, human herpesvirus 7 and immunophenotypic profile of inflammatory infiltrate in marginal chronic periodontitis
Human chronic periodontitis is an inflammatory process characterized by dense accumulation of immune cells in the periodontal tissue. The periodontitis can lead to loss of teeth in the patient and the pathogenesis of this disease is not completely known. This study tested the hypothesis that cells within inflammatory infiltrate can harbor betaherpesviruses a

9. Immunophenotypic characterization of patients with American cutaneous leishmaniasis prior to and after treatment in Pernambuco, Brazil
Leishmania infections induce a specific activation of host immunological response, particularly characterized by T cell expansion. Studies indicate the importance of the balance between CD4+ and CD8+ T cells, in which the first ones would have their number reduced during the healing process. Meanwhile, CD25+ T cells have been associated with the suppression

10. Comparing two human umbilical cord mesenchymal stem cell isolation protocols
Human umbilical cord is a rich source of mesenchymal stem cells (MSCs) as reported in many studies. Many techniques are used to obtain these cells and their variations are related to the part of the tissue from which the stem cells can be extracted (umbilical vein, arteries, Wharton’s jelly or the whole umbilical cord - UC). In this sense, it is really imp

Avaliação da citogenética convencional e molecular em portadores de leucemia promielocítica aguda no Serviço de Hematologia do Hospital das Clínicas da Faculdade de Medicina da USP / Conventional and molecular cytogenetics in patients with acute promyelocytic leukemia of the Hematology Service of Clinical Hospital of São Paulo Medical School
INTRODUCTION: Acute promyelocytic leukemia (APL) is a distinct subtype of acute myeloid leukemia (AML), characterized by clonal expansion of myeloid precursors blocked at promyelocytic stage, risks of coagulopathy and presence of chromosomal translocations involving RAR (retinoic acid receptor ) gene. Corresponds to the M3 and M3variant subtypes of AML, acco

12. Malignant and tuberculous pleural effusions: immunophenotypic cellular characterization
INTRODUCTION AND OBJECTIVES: Tuberculosis and cancer are the main causes of pleural effusion. Pleural involvement is associated with migration of immune cells to the pleural cavity. We sought to characterize the immunophenotype of leukocytes in the pleural effusion and peripheral blood of patients with tuberculosis or malignancy. METHODS: Thirty patients wit
