1. The relevance of a bank with genotyped platelets donors
ABSTRACT Objective: Describe the clinical and laboratory characteristics and the transfusion strategy of patients at Hospital Israelita Albert Einstein with platelet refractoriness and identify their etiological characteristics. Standardize the platelet immunofluorescence technique by flow cytometry as a test for platelet compatibility in immune platelet re

2. Atividade gelatinolítica in situ e imuno-expressão das metaloproteinases 2 e 9 em lesões potencialmente malignas e carcinomas espinocelulares bucais / In situ gelatinolytic activity and immunoexpression of metalloproteinases 2 and 9 in oral potentially malignant lesions and squamous cell carcinomas
The transition from normal oral mucosa to invasive carcinoma has a complex and multifactorial etiology. Oral leukoplakia (OL) is regarded as the most prevalent potentially malignant oral lesion, with a higher tendency for malignant transformation if compared to normal oral mucosa. Although an increased activity of matrix metalloproteinases (MMPs) 2 and 9 in

3. Molecular basis for the diagnosis and treatment of acute promyelocytic leukemia
Acute promyelocytic leukemia is characterized by gene rearrangements that always involve the retinoic acid receptor alpha on chromosome 15. In the majority of patients t(15;17) is detected, which generates the promyelocytic leukemia gene/retinoic acid receptor alpha rearrangement. This rearrangement interacts with several proteins, including the native promy

4. DinÃmica da IgA secretora especÃfica na lÃgrima empacientes portadores de uveÃte posterior ativa presumivelmente por Toxoplasma gondii durante o primeiro trimestre da doenÃa
Toxoplasma gondii (T.gondii) is the main cause of posterior uveitis and toxoplasmic retinochoroiditis is considered the most common infection of the retina. Serological tests are important tools for the diagnosis of toxoplasmosis, but in ocular toxoplasmosis, usually there is no correlation between levels of serum antibodies and eye symptoms in the patient.

5. Avaliação da contaminação de ostras (Crassostrea rhizophorae) por especies de Cryptosporidium e Giardia em um ambiente de estuario do litoral de São Paulo / Evaluation of the contamination of oysters (Crassostrea rhizophorae) by species of Cryptosporidium and Giardia in a estuarine environment from São Paulo coast
Bivalve molluscs are great filter feeders that may accumulate and concentrate substances, particles and even pathogens in their tissues, if the places that they inhabit or are cultivated receive contaminated effluents dispose. These animals, which serve as biological indicators of faecal contamination, may transmit the protozoa accumulated in their tissues,

6. Caracterização dos receptores P2 em eosinófilos de ratos e possíveis papéis funcionais. / Characterization of the P2 receivers in eosinophils of rats and possible functional papers.
ATP and other nucleotides can be released from cells through regulated pathways or following the loss of plasma membrane integrity. Once outside the cell, these compounds take on new roles as intercellular signaling molecules that elicit a broad spectrum of physiological responses through the activation of numerous cell surface receptors. These nucleotides a

7. Porphyria cutanea tarda. Evolution study of the clinical and laboratory features: biochemistry, immunofluorescence and light microscopy / "Porfiria cutânea tardia. Estudo evolutivo das características clínicas e laboratoriais: bioquímica, imunofluorescência e microscopia óptica"
Porphyria cutanea tarda is caused by the inherited or acquired partial deficiency of the uroporphyrinogen decarboxylase enzyme activity, resulting in the accumulation of uroporphyrin and hepta-carboxyl porphyrinogen in the liver. The purpose of this study was to investigate the clinical and laboratory features: biochemistry and the alterations on skin morpho

8. Canine experimental infection: intradermal inoculation of Leishmania infantum promastigotes
Five mixed breed dogs were inoculated intradermally (ID) with cultured virulent stationary phase promastigotes of Leishmania infantum Nicole, 1908 stocks recently isolated. Parasite transformations in the skin of ID infected dogs were monitored from the moment of inoculation and for 48 h, by skin biopsies. Anti-Leishmania antibody levels were measured by ind

9. Desenvolvimento de uma tecnica imunoenzimatica (Elisa) rapida e quantitativa para o imunodiagnostico da doença de Chagas
Chagas disease, an infection caused by the parasite Trypanosoma crnzi, is generally asymptomatic or is associated with mild, non-specific clinical manifestations in immunocompetent subjects. Severe cardiac and/or digestive system abnorrnalities may develop in chronically infected patients, but these clinical manifestations are usually preceded by many years

10. Utilidade da pesquisa de anticorpos IgA anti-toxoplasma gondii para o diagnostico sorologico da toxoplasmose aguda adquirida
Toxoplasmosis, an infection caused by the intracellular parasite Toxoplasma gondii, is generally asymptomatic or is associated with mild, nonspecific clinical manifestations in immunocompetent subjects. The detection of Toxoplasma-specific antibodies has been considered the most valuable tool for diagnosing toxoplasmosis. Serological diagnosis of acute toxop

11. An immunofluorescence method for the diagnosis of primary syphilis using an absorption technique
An immunofluorescence technique for demonstrating Treponema pallidum in fixed films made from suspected chancre exudate is described. The method used is basically a reversal of the fluorescent treponemal antibody absorption test. It makes use of the fact that by using a syphilitic serum from which group antibody has been absorbed by an extract of Reiter trep
