13. Algoritmos e arquiteturas para processamento de documentos digitalizados monocromÃticos
Em projetos de digitalizaÃÃo de alto volume de documentos, a imagem dos documentos digitalizados pode ser gerada com vÃrios defeitos acarretando dificuldades desde a sua leitura atà sua transcriÃÃo automÃtica. AlÃm disso, o alto volume de documentos a serem processados gera a necessidade de automatizaÃÃo do processo de digitalizaÃÃo e à procura

14. Espectroscopia de fluorescência na detecção de lesões quimicamente induzidas por agente carcinogênico na borda lateral da língua-estudo in vivo / Fluorescence spectroscopy to detection of chemically induced lesion at the lateral vorder of the tongue - in vivo study.
The diagnostic validity of the fluorescence spectroscopy in the discrimination of induced lesions at lateral border of the tongue of hamsters was investigated in this study. The animal model using chemical induction with DMBA (dimethylbenzanthracene) was chosen for the carcinogenesis phases comparable to the ones observed at oral cancer development in humans

15. Trachoma among the Yanomami Indians
The Yanomami are one of the last primitive groups of Indians living in Brazil. They have almost no contact with other cultures. The epidemiology of eye disease among Yanomami is virtually unknown. For the first time, a trachoma survey was conducted among Yanomami Indians in the State of Amazonas near the Venezuelan border of the Brazilian rain forest. Ophtha

16. Possible Role of Root Border Cells in Detection and Avoidance of Aluminum Toxicity1
Root border cells are living cells that surround root apices of most plant species and are involved in production of root exudates. We tested predictions of the hypothesis that they participate in detection and avoidance of aluminum (Al) toxicity by comparing responses of two snapbean (Phaseolus vulgaris) cultivars (cv Dade and cv Romano) known to diffe

17. T-DNA and opine synthetic loci in tumors incited by Agrobacterium tumefaciens A281 on soybean and alfalfa plants.
We report here the molecular characterization of transferred DNA (T-DNA) in leguminous tumors incited by Agrobacterium tumefaciens A281 harboring the tumor-inducing plasmid pTiBo542. The T-DNA is composed of two regions named TL (left portion)-DNA and TR (right portion)-DNA, in accordance with the nomenclature for the octopine strains. TL-DNA is defined by s

18. Cardiac MRI of myocardial salvage at the peri-infarct border zones after primary coronary intervention
The purpose of this study was to use cardiac MRI to define the morphology of the reversibly injured peri-infarct border zone in patients treated with primary percutaneous coronary intervention (PPCI) for acute ST elevation myocardial infarction. In 15 patients, T2-weighted myocardial edema imaging was used to identify the ischemic bed or area at risk (AAR),

19. Two Different Bacillus thuringiensis Delta-Endotoxin Receptors in the Midgut Brush Border Membrane of the European Corn Borer, Ostrinia nubilalis (Hübner) (Lepidoptera: Pyralidae)
Binding of three Bacillus thuringiensis insecticidal crystal proteins (ICPs) to the midgut epithelium of Ostrinia nubilalis larvae was characterized by performing binding experiments with both isolated brush border membrane vesicles and gut tissue sections. Our results demonstrate that two independent ICP receptors are present in the brush border of O. nubil

20. Internal promoters of the his operon in Salmonella typhimurium.
Two internal promoters in the his operon of Salmonella typhimurium have been precisely mapped genetically. The internal promoters are found in, or very close to, gene border regions in the his operon. The his operon was examined for the presence of additional internal promoters whose transcripts were sensitive to rho-mediated transcription termination and th

21. Dynamic three-dimensional echocardiography combined with semi-automated border detection offers advantages for assessment of resynchronization therapy
Simultaneous electrical stimulation of both ventricles in patients with interventricular conduction disturbance and advanced heart failure improves hemodynamics and results in increased exercise tolerance, quality of life. We have developed a novel technique for the assessment and optimization of resynchronization therapy. Our approach is based on transthora

22. Detection of hog cholera virus and differentiation from other pestiviruses by polymerase chain reaction.
Reverse transcription coupled with the polymerase chain reaction (RT-PCR) was used for the detection and differentiation of pestiviruses. For this purpose, one primer pair was selected from a highly conserved region of the genome of pestiviruses. Using these primers (PEST 1-PEST 2), DNA fragments of between 72 and 74 bp could be amplified from all pestivirus

23. Universal PCR primers for detection of phytopathogenic Agrobacterium strains.
Two PCR primer pairs, based on the virD2 and ipt genes, detected a wide variety of pathogenic Agrobacterium strains. The endonuclease domain of VirD2 protein, which cleaves transferred DNA (T-DNA) border sequences, is highly conserved; primer oligonucleotides specific for the endonuclease portion of virD2 detected all pathogenic strains of Agrobacterium test

24. Presumptive diagnostic differentiation of hog cholera virus from bovine viral diarrhea and border disease viruses by using a cDNA nested-amplification approach.
Hog cholera virus (HCV), bovine viral diarrhea virus (BVDV), and border disease virus (BDV) are closely related pestiviruses. BVDV and BDV are found worldwide but seldom cause disease in swine. In contrast, HCV has been successfully eradicated from swine in several nations but poses a potentially devastating threat to them because of its great virulence. Rap
