4. Standardization of enzyme immunoassay (ELISA) for serology, detection and quantification of porcine circovirus type 2 / Padronização de ensaios imunoenzimáticos (ELISA) para sorologia, detecção e quantificação do circovírus suíno 2
Porcine circovirus 2 (PCV-2) is the major causative agent of postweaning multisystemic wasting syndrome (PMWS) and is associated with different syndromes that affect the swine. The term PCVAD (Porcine circovirus associated diseases) was introduced in 2006 to gather many diseases. Since serological studies are essential for monitoring the virus, the aim of th

5. Expressão de reguladores da reabsorção óssea (RANK/RANKL/OPG) e formação óssea (osteocalcina) em lesões realcionadas ao osso e osteossarcoma / Markers of bone remodeling in neoplastic and bone-related lesions
The RANK (receptor activator of nuclear factor Kappa-Beta)-RANKL (receptor activator of nuclear factor-kappa beta ligand)-OPG (osteoprotegerin) system is the principal means of differentiating and activating osteoclasts. Changes along this path have been associated with various bone related lesions (BRL), whether benign or malignant, such as osteosarcoma (OS

6. Comparison of a rapid cytomegalovirus pp65 antigenemia assay revealed by immunofluorescence to an in-house assay revealed by immunoperoxidase for diagnosis in solid organ transplant recipient patients
Cytomegalovirus (CMV) antigenemia is still one of the two major assays available for diagnosis and monitoring of CMV infections. A commercial rapid test recently available in Brazil for quantification of human cytomegalovirus pp65 antigenemia revealed by immunofluorescence technique was compared with the original in-house method revealed by immunoperoxidase

7. Cardiac and pulmonary alterations in symptomatic and asymptomatic dogs infectednaturally with Leishmania (Leishmania) chagasi
Fifteen symptomatic and seven asymptomatic dogs infected naturally with Leishmania chagasi were examined in order to identify the presence of parasites and changes in heart and lung. Histopathological, cytological, and immunohistochemical analyses were performed on samples of heart and lung tissues. An inflammatory reaction characterized by inflammatory mono

9. Comparison of immunoperoxidase and immunofluorescence assays for pp65 cytomegalovirus antigen in immunocompromised patients
We compared the pp65 antigen detection by an in house method (immunoperoxidase assay) and by a commercial kit (immunofluorescence assay) available for cytomegalovirus infection diagnosis in immunocompromised patients. Sixty-four blood samples were analyzed in duplicate for both techniques. Eight-six percent of the samples had concordant qualitative results.

11. Interstitial and Langerhans' dendritic cells in chronic periodontitis and gingivitis
The aim of the present study was to compare quantitatively the distribution of dendritic cell subpopulations in chronic periodontitis and gingivitis. Fourteen biopsies from patients with chronic periodontitis and fifteen from patients with gingivitis were studied. An immunoperoxidase technique was used to quantify the number of Langerhans' cells (CD1a) and i

12. ImunohistoquÃmica e anÃlise digital de imagens no carcinoma ductal infiltrante
The immunohistochemistry is a technique of great help in diagnosing diseases of the breast, including tumors. Equally important, the analysis of digital images is being increasingly used in studies of changes in the breast. This study aimed to quantify the expression of the antibody morfometricamente through immunoperoxidase as in normal breast tissue, and i
