1. From Charcot’s descriptions to the current understanding of neuropsychiatric symptoms in multiple sclerosis
RESUMO Os distúrbios neuropsiquiátricos na esclerose múltipla são conhecidos desde a descrição clínico-patológica original de Charcot no final do século XIX. Charcot nas últimas décadas de sua vida se envolveu no campo da neuropsiquiatria. Isso produziu uma batalha de escolas rivais na época que ainda ecoa até hoje. A intuição de Charcot, incl

2. Intercessão fílmica: um encontro sempre em vias de acontecer
Resumo Este texto, que é um recorte de uma pesquisa de doutorado, intenciona movimentar diferentes fluxos de pensamentos a partir de uma intercessão fílmica, incitando a pensar uma experiência educativa. Busca dar atenção àquilo que tem a potência de afetar e inquietar em um encontro fílmico, possibilitando a produção de diferentes arranjos e tess

3. Renal oxygen content is increased in healthy subjects after angiotensin-converting enzyme inhibition
OBJECTIVE: The association between renal hypoxia and the development of renal injury is well established. However, no adequate method currently exists to non-invasively measure functional changes in renal oxygenation in normal and injured patients. METHOD: R2* quantification was performed using renal blood oxygen level-dependent properties. Five healthy norm

4. Nos En(tre)cantos de Dulcinea Del Toboso : (Uma cantata cênica)
The study subject of this cantata is Dulcinea del Toboso, the peerless Lady created by Don Quixote in the narrative called The Ingenious Gentleman Don Quixote de la Mancha, written by Miguel de Cervantes Saavedra in the years 1605 (first book) and 1615 (second book). The research is based on two principles: the concepts of silence and female extracted from t

5. Estudo do composto intermetálico GdAl2 via ressonância magnética nuclear em campo magnético externo nulo / Zero-field NMR study of intermetallic compound GdAl2
Recentemente, o Laboratório de Espectroscopia de Alta Resolução por RMN (LEAR), do Instituto de Física de São Carlos - USP, decidiu iniciar pesquisa na área de materiais magnéticos sem a aplicação de campo magnético externo. Por esta razão, montou-se um espectrômetro de RMN em campo zero (RMNz), tendo como componente principal um console de banda

6. AMONG RUINS AND ECHOES: MULTIPLE VISIONS OF CANUDOS / ENTRE RUÍNAS E ECOS: CANUDOS EM MÚLTIPLAS VISÕES
A presente tese é dedicada à investigação crítica de discursos variados, produzidos em torno da Guerra de Canudos. O corpus da análise é constituído por material documental e jornalístico da época a respeito do evento, bem como pelos ecos da guerra colhidos em múltiplas representações historiográficas, literárias, imagéticas e cinematográfic

7. Two-dimensional infrared spectroscopy of peptides by phase-controlled femtosecond vibrational photon echoes
Two-dimensional infrared spectra of peptides are introduced that are the direct analogues of two- and three-pulse multiple quantum NMR. Phase matching and heterodyning are used to isolate the phase and amplitudes of the electric fields of vibrational photon echoes as a function of multiple pulse delays. Structural information is made available on the time sc

8. Echocardiographic assessment of the Ionescu-Shiley pericardial xenograft in the aortic position
Echocardiograms of 30 patients with a normally functioning Ionescu-Shiley pericardial xenograft valve in the aortic position were analyzed to delineate the ultrasonic patterns produced by this bioprosthesis. The pericardial leaflets were recorded as thin, discrete echoes that were similar in configuration to the native aortic valve. Maximum systolic excursio

9. Echo-delay resolution in sonar images of the big brown bat, Eptesicus fuscus
Echolocating big brown bats (Eptesicus fuscus) broadcast ultrasonic frequency-modulated (FM) biosonar sounds (20–100 kHz frequencies; 10–50 μs periods) and perceive target range from echo delay. Knowing the acuity for delay resolution is essential to understand how bats process echoes because they perceive target shape and texture from the delay separat

10. Abnormal aortic valve echoes in mitral prolapse. Echocardiographic features of floppy aortic valve.
The following distinctive combination of M-mode and two dimensional echocardiographic abnormalities of the aortic valve was observed in a group of 12 patients, of whom 11 had mitral valve prolapse. On two dimensional scans, the aortic cusps were freely mobile but appeared thickened or folded. On M-mode records, cusp excursion was normal: there was well defin

11. The Echocardiographic Spectrum of Atrial Myxoma: A Ten-Year Experience
We analyzed the echocardiograms of 28 patients with a left atrial myxoma and two with a right atrial myxoma. Our purpose was to evaluate the value of echocardiography for the diagnosis of these cardiac masses. Only 59% of the m-mode echocardiograms in patients with a left atrial myxoma showed the characteristic findings of multiple diastolic echoes within th

12. Echocardiographic assessment of mitral valve calcification.
The mitral valve was assessed by echocardiography in 20 patients, aged 27 to 67 years, who subsequently underwent mitral valve replacement. After removal, the mitral valve cusps were examined by direct measurement, radiography, and quantitative calcium extraction. Increased thickness of the E-F echo was found where calcification or fibrosis was present, diff
