25. Infectious bursal disease: evaluation of maternal immunity and protection by vaccination of one-day old chicks against challenge with a very virulent virus isolate
Broiler chicks belonging to two poultry companies, A and B, with different breeders' vaccination programs were challenged with a very virulent strains of infectious bursal disease virus (vvIBDV), genotyped as G11. Birds were separated in four groups, two vaccinated at the first day of life and two unvaccinated. They were then challenged at the 1st, 4th, 7th,

26. Infectious bursal disease: evaluation of pathogenicity of commercial vaccines from Brazil in specific pathogen free chichens
Infectious Bursal Disease (IBD) is a chicken disease economically important for the poultry industry in function of the immune depression that it causes. Disease control is made with different vaccines and vaccination programs. In present work, the pathogenicity of 3 intermediate vaccines (I1, I2 and I3), 2 intermediate more pathogenic (IP1 and IP2) and 3 va

27. Hibernoma lipoma-símile: um mimetizador do lipoma atípico/lipossarcoma bem diferenciado
Hibernomas são tumores benignos que apresentam diferenciação similar à das células do tecido adiposo marrom. Recentemente, variantes incomuns desta neoplasia foram descritas, incluindo hibernomas mixóides, de células fusiformes e lipoma-símile. O hibernoma lipoma-símile (HLS) é caracterizado por adipócitos maduros entremeados por uma pequena quant

28. Optimization algorithms of functional units test plans for BIST circuits. / Algoritmos de otimização de planos de teste de unidades funcionais para circuitos BIST.
Grandes saltos tecnológicos viabilizaram a integração de circuitos digitais de alta complexidade, com centenas de pinos e milhões de transistores. Sistematicamente, dispositivos eletromecânicos estão sendo substituídos por Circuitos Integrados (CIs) que contêm sistemas inteiros, ampliando o uso generalizada da eletrônica. Com o aumento da complexida

29. Central nervous system lesions in von Hippel-Lindau syndrome.
CNS manifestations were studied in 97 gene carriers of von Hippel-Lindau syndrome (HLS). Haemangioblastomas of the CNS were found in 43 patients (44%), 23 females and 20 males. The mean age at diagnosis was 39 years (12-73 years). A total of 93 haemangioblastomas were detected of which 74% were intracranial and 26% were located in the spinal cord; 75% were p

30. Interregional variations in measures of health from the Health and Lifestyle Survey and their relation with indicators of health care need in England.
STUDY OBJECTIVE--The aim was to assess the extent to which a range of routinely available need indicators which have been suggested for use in NHS spatial resource allocation formulas were associated geographically in England with the different dimensions of population health status collected in the 1985/86 Health and Lifestyle Survey (HLS). DESIGN--Regional

31. A new member of the plasma protease inhibitor gene family.
A 2.1-kb cDNA clone representing a new member of the protease inhibitor family was isolated from a human liver cDNA library. The inhibitor, named human Leuserpin 2 (hLS2), comprises 480 amino acids and contains a leucine residue at its putative reactive center. HLS2 is about 25-28% homologous to three human members of the plasma protease inhibitor family: an

32. Continuing education needs of hospital librarians.
The Hospital Library Section (HLS) of MLA conducted a survey of its members to determine their continuing education needs and preferences. A questionnaire mailed with the HLS Newsletter gathered information in four general areas: preferred modes of continuing education, subjects viewed as most important, motivators and deterrents, and topics for presentation

33. Genetic Analysis of Ethylene Signal Transduction in Arabidopsis Thaliana: Five Novel Mutant Loci Integrated into a Stress Response Pathway
The response of Arabidopsis thaliana etiolated seedlings to the plant hormone ethylene is a conspicuous phenotype known as the triple response. We have identified genes that are required for ethylene perception and response by isolating mutants that fail to display a triple response in the presence of exogenous ethylene. Five new complementation groups have

34. The Escherichia coli MutL protein stimulates binding of Vsr and MutS to heteroduplex DNA.
Vsr DNA mismatch endonuclease is the key enzyme of very short patch (VSP) DNA mismatch repair and nicks the T-containing strand at the site of a T-G mismatch in a sequence-dependent manner. MutS is part of the mutHLS repair system and binds to diverse mismatches in DNA. The function of the mutL gene product is currently unclear but mutations in the gene abol

35. Removal of polymerase-produced mutant sequences from PCR products
Heteroduplex DNA lacking d(GATC) methylation is subject to mismatch-provoked double-strand cleavage at d(GATC) sites in a reaction dependent on MutH, MutL, MutS, and ATP. We have exploited this reaction to develop a method for removal of polymerase-produced mutant sequences that arise during sequence amplification by PCR. After denaturation and reannealing,

36. Direct Selection for Mutators in Escherichia coli
We have constructed strains that allow a direct selection for mutators of Escherichia coli on a single plate medium. The plate selection is based on using two different markers whose reversion is enhanced by a given mutator. Plates containing limiting amounts of each respective nutrient allow the growth of ghost colonies or microcolonies that give rise to fu
