1. Entre duas Barcas: notas sobre regimes de visualidade e de discursos na história da arte.
resumo Este texto parte do contraste manifesto pela associação entre a Barge de Robert Rauschenberg e Le Radeau de la Méduse de Théodore Géricault, com vistas à discussão dos contextos de suas recepções, levando em conta a necessidade de marcar retornos críticos e deslocamentos conceptuais ao longo dos desenvolvimentos diacrônicos de suas fortunas

2. Comparison between inverted and unprocessed digitized radiographic imaging in periodontal bone loss measurements
The advances in digital imaging technology in dentistry have provided an alternative to film-based radiography and have given new options to detect periodontal bone loss. The purpose of this study was to compare inverted and unprocessed digitized radiographic imaging in periodontal bone loss measurements. Thirty-five film-based periapical radiographs of pati

3. Influência de diferentes meios de digitalização de radiografias na avalição de cáries proximais / Comparative performance of indirect digitized radiographs for detecting approximal caries
To evaluate the performance of conventional and indirect digital radiography and the effect of JPEG and TIFF file formats for detecting proximal surface caries. Fifty-six extracted teeth were mounted in blocks and radiographed with Insight conventional film. Films were digitized by two flatbed scanners (Canon CanonScan and Genius ColorScan) and four digital

4. Rapid quantitation of DNA spot hybridization by flatbed scintillation counting.
The flatbed scintillation counting system (Betaplate) was used for quantitative measurement of the radioactive hybridization signal in detection of adenovirus and papillomavirus DNA in clinical specimens. In this method, 96 samples on a nylon membrane can be handled as a single entity throughout the hybridization and counting procedure. The technique is sens

5. Evaluation of Five Membrane Filtration Methods for Recovery of Cryptosporidium and Giardia Isolates from Water Samples
We evaluated the efficiency of five membrane filters for recovery of Cryptosporidium parvum oocysts and Giardia lamblia cysts. These filters included the Pall Life Sciences Envirochek (EC) standard filtration and Envirochek high-volume (EC-HV) membrane filters, the Millipore flatbed membrane filter, the Sartorius flatbed membrane filter (SMF), and the Filta-

6. Pteridines as nonretinal regulators of light-dependent melatonin biosynthesis.
6-Formylpterin was purified by paper chromatography, and bovine pineal hydroxyindole-O-methyltransferase (S-adenosyl-L-methionine:N-acetylserotonin O-methyl-transferase; EC 2.1.1.4) was purified by flat-bed gel electrofocusing. Fractions of the methyltransferase with isoelectric points at pH 5.0, 5.7, and 5.2 were tested in the presence of 6-formylpterin, an

7. Five novel plasmid-determined beta-lactamases.
Five novel plasmid-determined beta-lactamases named TLE-1, OXA-4, OXA-5, OXA-6, and OXA-7 were detected in ampicillin-resistant isolates of Escherichia coli and carbenicillin-resistant strains of Pseudomonas aeruginosa. TLE-1 resembled TEM-1 in substrate profile and reactions with inhibitors but differed in isoelectric point (5.55) and enzyme banding pattern

8. Cold-Resistant and Cold-Sensitive Maize Lines Differ in the Phosphorylation of the Photosystem II Subunit, CP29.
The effects of low temperature on the relative contributions of the reaction center and the antenna activities to photosystem II (PSII) electron transport were estimated by chlorophyll fluorescence. The inhibition of PSII photochemistry resulted from photo-damage to the reaction center and/or a reduced probability of excitation energy trapping by the reactio

9. Slot immunoblot assay for detection and quantitation of periodontal disease-associated microorganisms in dental plaque.
A rapid method for qualitative and quantitative detection of specific oral microorganisms from subgingival dental plaque is described. Plaque samples were suspended in phosphate-buffered saline containing protease inhibitors and 0.5% formaldehyde, briefly sonicated to disperse bacterial aggregates, and applied to nitrocellulose membranes in a slot blot manif

10. Crossed immunoelectrophoretic analysis of two antigen extracts of Thermoactinomyces candidus.
A pyridine extract antigen and a double-dialysis antigen (DDA) obtained from Thermoactinomyces candidus were analyzed by crossed immunoelectrophoresis. In addition, the heat lability, pronase sensitivity, and isolectric points of the components of the DDA were determined. By using antisera raised against crude pyridine extract antigen, two immunogenic compon

11. Evaluation of a Scanner-Assisted Colorimetric MIC Method for Susceptibility Testing of Gram-Negative Fermentative Bacteria
We describe the ScanMIC method, a colorimetric MIC method for susceptibility testing of gram-negative fermentative bacteria. The method is a slight modification of the National Committee for Clinical Laboratory Standards (NCCLS) recommended broth microdilution method that uses a redox indicator 2,3,5-triphenyltetrazolium chloride (TTC) to enhance the estimat

12. Purification and characterization of inducible beta-lactamases in Aeromonas spp.
beta-Lactamases from Aeromonas hydrophila and A. sobria were purified and characterized. Both species produced beta-lactamases that were inducible by either cefoxitin or imipenem. These species were resistant to ampicillin and cephalothin but not imipenem. Isoelectric focusing of sonic extracts revealed one band at pI 8.0 and a second band at pI 7.0 for A. h
