1. The added value of non-contrast 3-Tesla MRI for the pre-operative localization of hyperparathyroidism
Abstract Objective: We investigated the efficacy of non-contrast 3-Tesla MR imaging added to the combination of sestamibi with99mTc (MIBI) scintigraphy and Ultrasonography (US) for the pre-operative localization of Primary Hyperparathyroidism (PHPT) lesions. Methods: A total of 34 parathyroid glands, including nine normal glands, were examined with MIBI, U

2. Assessment of the diagnostic performance of two new tools versus routine screening instruments for bipolar disorder: a meta-analysis
Objective: The present meta-analysis was conducted to determine the diagnostic accuracy of the bipolarity index (BI) and Rapid Mode Screener (RMS) as compared with the Bipolar Spectrum Diagnostic Scale (BSDS), the Hypomania Checklist (HCL-32), and the Mood Disorder Questionnaire (MDQ) in people with bipolar disorder (BD). Methods: We systematically searched

3. Can p63 serve as a biomarker for diagnosing giant cell tumor of bone? A systematic review and meta-analysis
ABSTRACT BACKGROUND: Tumor protein p63 (p63) has been reported to be highly expressed in giant cell tumor of bone (GCTB). Whether p63 can be treated as a diagnostic marker for GCTB remains unclear. OBJECTIVE: We conducted a meta-analysis to evaluate the applicability of p63 in diagnosing GCTB. DESIGN AND SETTING: Systematic review and meta-analysis carrie

4. New Strategy for Streptavidin Detection Using AuNRs/PAAm Hydrogel Composites
Localized surface plasmon resonance (LSPR) is a collective oscillation of free electrons induced by the incident light in nanometric surfaces of conductive materials. Gold nanorods (AuNRs) have been studied for plasmonic devices due to their anisotropic properties. Herein, we report the construction of a specific biosensor using polyacrylamide (PAAm) as the

5. Ultrasound Versus Contrast-Enhanced Magnetic Resonance Imaging for Subclinical Synovitis and Tenosynovitis: A Diagnostic Performance Study
OBJECTIVES: Radiographic manifestations of synovitis (e.g., erosions) can be observed only in the late stage of rheumatoid arthritis. Ultrasound is a noninvasive, cheap, and widely available technique that enables the evaluation of inflammatory changes in the peripheral joint. In the same way, dynamic contrast-enhanced magnetic resonance imaging (MRI) enabl

6. EVALUATION OF SILICA NANOPARTICLE COLLOIDAL STABILITY WITH A FIBER OPTIC QUASI-ELASTIC LIGHT SCATTERING SENSOR
Abstract Colloidal silica is an important biocompatible, inert and non-toxic material for imaging, therapy, and drug delivery biomedical applications. In this context, the evaluation of colloidal suspensions and their stabilities by a Fiber Optic Quasi-Elastic Light Scattering sensor is proposed. Two different silica nanoparticles were prepared and character

7. HISTÓRIA DA HISTORIOGRAFIA ANALÍTICA E SENTIMENTAL: PROPOSIÇÕES SOBRE DISTÂNCIA HISTÓRICA, NOSTALGIA E VISÕES DA MODERNIDADE BRASILEIRA NOS OITOCENTOS
Resumo Este artigo tem como proposta central discutir, a partir de problemas da história da historiografia, a emergência da categoria analítica distância histórica e as possibilidades de modular o tempo a partir de diferentes possibilidades de representação do tempo. Lançamos nossos olhares para o final do século XIX brasileiro, destacando literatur

8. Mycotoxin contamination of diets for beef cattle finishing in feedlot
ABSTRACT The objective of this survey was to identify what mycotoxins were present in ingredients used in diets offered to beef cattle in feedlots and their concentrations. The survey covered 30 Brazilian feedlots located in the five major beef-producing states. Samples of total mixed ration (TMR) and ingredients were collected and analyzed for mycotoxin usi

9. Multi-Energy Calibration: A Practical Method for Determination of Macro and Micro Nutrients in Meat by ICP OES
The multi-energy calibration (MEC) was evaluated for the determination of Ca, Cu, Fe, K, Mg, Na, P, S, and Zn in meat samples by inductively coupled plasma optical spectrometry (ICP OES). This calibration method consists of using only two calibration standards and several atomic and ionic emission wavelengths with different sensitivities to determine the ana

10. THEORETICAL STUDIES ON THE NEW HIGH-NITROGEN EXPLOSIVES N14 AND N18
The power of a compound is enhanced by the direct connection of nitrogen atoms, and its stability can be improved through conjugated structure. So novel high energy density materials N14 (1,6-dihydro-1,2,3,3a,4,5,5a,6,7,8,8a,9,10,10a-tetradecazapyrene) and N18 (1,2,2a,3,4,4a,5,6,6a,7,8,8a,9,10,10a,11,12a-octadecazacoronene) were designed, and their structure

11. Celso Furtado as ‘Romantic Economist’ from Brazil’s Sertão
RESUMO Em The Romantic Economist (2009), Richard Bronk lamenta que o pensamento iluminista tenha dominado a economia durante sua formação como ciência. O “Movimento Romântico” seria um contraponto, mas foi mantido distante. A economia abraçou a centralidade da racionalidade e preceitos iluministas, tornando-se uma “física-social”. Desde então,

12. Mangue Bangue, filme-limite.
RESUMO O propósito deste artigo é apresentar uma análise do “filme-limite” Mangue Bangue (1971), de Neville d’Almeida, tendo-se em vista a sua proximidade a questões e propostas contemporâneas do parceiro do cineasta, o artista plástico Hélio Oiticica, e ressaltando a convergência de ambos os artistas na experimentação com a forma cinema em i
