1. Effect of different sources of selenium on performance and characteristics of immune system of broiler chickens
ABSTRACT An experiment was conducted based on a completely randomized design with 500 Ross 308 broiler chickens to investigate the effect of three different sources of selenium on performance and characteristics of immune system. Chickens were arranged in 10 treatments and five repetitions (10 chickens for each repetition). Ten treatments of experimental die

2. Immunology Interaction fetal-maternal in asthma: immunological reactive patterns in blood and colostrum from healthy and asthmatic mothers and in blood from their respective newborns. / Imunologia das interações materno-fetais na asma: padrões de reatividade imunológica no colostro e no sangue de mães asmáticas e no sangue de cordão de seus respectivos recém-nascidos.
Asthma has been presenting higher prevalence rates worldwide. The objective of this work is to evaluate the presence of cellular elements and humoral indicative in blood and colostrums of healthy and asthmatic mothers and in cord umbilical blood of their newborn (NB). Lower production of IgG from asthmatic mothers was observed. Dendritic cells of asthmatic m

3. Identificação das deleções e mutações do gene P53 em pacientes com mieloma multiplo
Multiple myeloma (MM) is a neoplastic disease characterized by the accumulation of plasma cells in the bone marrow (BM) with consequent osteolysis, comprimising hematopoiesis and the synthesis of normal immunoglobins and the production of monoclonal immunoglobin or its fragments. The survival observed for patients with the disease varies from a few months to

4. Interação de lectinas de semente de jaca (Artocarpus integrifolia) com glicoproteinas da saliva e soro humano
Interaction of lectins of jack seeds Artocarpus integrifolia, with salivay and human serum glycoproteins. Lectins are proteins which bind to specific saccharides in polysacharides, glycoproteins or glycolipds. Although originally described in plants, they have been isolated from many diverse sources like bacterias and animal including smails, sponges, fish a

5. Temporal study of immunoglobin M seroreactivity to Borrelia burgdorferi in patients treated for Lyme borreliosis.
Forty-six patients with late Lyme disease who were considered improved or cured following treatment were monitored by immunoglobin M (IgM) immunoblotting (mean monitoring period, 27.6 months). There was a persistent IgM response in 32 (97%) of 33 initially positive patients. All but three showed a consistent number, type, and intensity of IgM bands over the

6. A simplified screening test for the diagnosis of allergy.
The Quidel allergy screen is a relatively rapid (less than 2 hours) multiallergen dipstick method for detecting specific immunoglobin E antibodies in serum. It was developed to answer the need of primary physician nonspecialists in allergy for a convenient in-office screening test for diagnosing allergy. The new test was evaluated against the benchmark diagn

7. Problems affecting performance of the fluorescent treponemal antibody-absorption test for syphilis.
Immunofluorescent staining of Treponema pallidum was studied to clarify the effect of three factors on the results of the fluorescent treponemal antibody-absorption test: (i) heat inactivation of sera at 56 degrees C for 30 min before testing, (ii) use of multicircle slides, and (iii) tungsten illumination to visualize and assess unstained treponemes on reac

8. Antibodies with Multiple Binding Functions. Induction of Single Immunoglobin Species by Structurally Dissimilar Haptens
Anti-hapten sera prepared in rabbits contain individual immunoglobulin species capable of binding several pairs of structurally diverse haptens A and B. (A = inosine, uridine, menadione, vitamin K1, ribonuclease; B = 2,4-dinitrophenyl). In antisera against hapten A subjected to isoelectric focusing, there are many anti-A immunoglobulin species, but only a sm

9. The complete nucleotide sequence of mouse immunoglobin gamma 2a gene and evolution of heavy chain genes: further evidence for intervening sequence-mediated domain transfer.
We have determined the complete nucleotide sequence (1990 base pairs) of mouse immunoglobulin gamma 2a gene, and compared it with the sequences of other gamma subclass genes so far sequenced, i.e. gamma 1 and gamma 2b genes. Divergence of the nucleotide sequence between a compared pair of the gamma genes varies extensively among different segments of the gen

10. Translation of individual host mRNA's in MPC-11 cells is differentially suppressed after infection by vesicular stomatitis virus.
Infection of MPC-11 mouse plasmacytoma cells by vesicular stomatitis virus results in 30 to 35% reduction in [35S]methionine incorporation into total proteins within 30 min postinfection. By 6 h postinfection, total protein synthesis is reduced by 80 to 90%. However, even by 30 min postinfection, a differential suppression of the synthesis of individual host

11. Development of a radioimmunoassay for Escherichia coli heat-stable enterotoxin: comparison with the suckling mouse bioassay.
Escherichia coli strains which produce heat-stable enterotoxin (ST) are usually identified by demonstrating the production of ST. At present, ST can be detected only by bioassay methods. Recently, we purified E. coli ST, which enabled us to develop a radioimmunoassay for ST. Radioiodination of ST was performed by the lactoperoxidase method, which resulted in

12. Saccharomyces cerevisiae RAD5-encoded DNA repair protein contains DNA helicase and zinc-binding sequence motifs and affects the stability of simple repetitive sequences in the genome.
rad5 (rev2) mutants of Saccharomyces cerevisiae are sensitive to UV light and other DNA-damaging agents, and RAD5 is in the RAD6 epistasis group of DNA repair genes. To unambiguously define the function of RAD5, we have cloned the RAD5 gene, determined the effects of the rad5 deletion mutation on DNA repair, DNA damage-induced mutagenesis, and other cellular
