25. First record of Tomato chlorotic spot virus in the USA
A tospovirus was identified in tomato plants from two counties in Florida by reverse transcription-PCR and sequencing of portions of the S, M and L genomic segments. The predicted amino-acid sequences of the N protein of PCR products from four plant samples were >96% identical to those of TCSV. Partial nucleic acid sequences of the L and M RNA were >97% iden

26. Antimicrobial activity of lactic acid bacteria and the spectrum of their biopeptides against spoiling germs in foods
The objective of this study was to isolate LAB from dairy, meat products and agro-industrial wastes and to investigate their antagonist activity. A total of 141 isolates were screened for the inhibitory effect on ten indicator strains in the agar spot test. Results showed that strain LBbb0141 contained antimicrobial compound with wide spectrum that inhibited

27. The effect of electric spot-welding on the mechanical properties of different orthodontic wire alloys
The aim of this study was to test the hypothesis that there is a direct relationship between surface structure and tensile strength of orthodontic alloys submitted to different levels of welding current. Three types of alloys were assessed. One hundred and eight cross-sectional test specimens ("X") were made, 18 for each wire combination, and divided into 6

28. Evolução e ecologia de tricomas em Bignonieae (Bignoniaceae): estruturas morfológicas de defesa anti-herbivoria? / Evolution and ecology of trichomes in Bignonieae (Bignoniaceae): morphological structures of anti-herbivory defense?
This thesis focused on the evolutionary-ecology of trichomes in the tribe Bignonieae (Bignoniaceae), and in the potential defensive role of these structures against herbivores. More specifically, we characterized four trichome morphotypes found in vegetative plant parts of representatives of the Bignonieae, as well as studied the macro-evolutionary patterns

29. Baropodometria na hanseníase e sua relação com a alteração de sensibilidade / Podometric evaluation in leprosy and it\ s relation with altered sensibility
Leprosy is a disease of chronic evolution that causes specific and slow inflammatory reaction, damaging the peripheral neural system. The detection of the sensibility loss is important to identify patients with peripheral neuropathy, and the standard method for it is the Semmes-Weinstein\ s monofilament sensibility test. One of the etiologic factors of the p

30. Genetic variability for disease resistance in Brazilian upland rice native germplasm.
Thirty nine rice genotypes were evaluated under dryland field conditions for resistance to leaf and neck blast, brown spot, leaf scald, narrow brown leaf spot and grain discolaration in 13 test sites during a three-year period. these include 17 land races, six traditional cultivars, 11 improved breeding lines and three exotic cultivars. There was a great div

32. Otimização do manejo da pinta preta causada por Guignardia citricarpa Kiely na produção ecológica de tangerinas cv. Montenegrina sob a ótica da pesquisa participativa / Optimization of management techniques of black spot (Guignardia citricarpa Kiely.) in ecological orchards of tangerine trees cv. montenegrinafrom the perspective of participatory research
In the state of Rio Grande do Sul many citric species are grown, the town of Montenegro, in Vale do Caí/RS stands out among the most important producers. For the production of fruits for in natura consumption most of the local farmers adopt technological packages that consist in the use of chemical inputs and in environmetal simplification. However, experim

34. Genomic alterations detected by comparative genomic hybridization in ovarian endometriomas
Endometriosis is a complex and multifactorial disease. Chromosomal imbalance screening in endometriotic tissue can be used to detect hot-spot regions in the search for a possible genetic marker for endometriosis. The objective of the present study was to detect chromosomal imbalances by comparative genomic hybridization (CGH) in ectopic tissue samples from o

35. Genotoxicity of lapachol evaluated by wing spot test of Drosophila melanogaster
This study investigated the genotoxicity of Lapachol (LAP) evaluated by wing spot test of Drosophila melanogaster in the descendants from standard (ST) and high bioactivation (HB) crosses. This assay detects the loss of heterozygosity of marker genes expressed phenotypically on the fly's wings. Drosophila has extensive genetic homology to mammals, which make

36. Validação do teste de marcha "Six Step Spot Test" em pacientes com esclerose múltipla no Brasil
As manifestações clínicas da esclerose múltipla (EM) são variáveis e o curso da doença não é linear, caracterizado por sintomas, acúmulo progressivo de incapacidades. Estas variações são difíceis de quantificar na prática clínica, motivo pelo qual surgiram diversos estudos para criação de instrumentos capazes de mensurar essas incapacidades
