The research focuses on the use of recycled aggregate (RA), from waste pieces generated during production in precast plants for self-compacting concrete (SCC) manufactured with a double sustainable goal: recycle manufacturing waste (consumption) and improvement of the thermal properties of the manufactured product (energy efficiency). For this purpose, a mechanical study to ensure technical fea...

High-resolution numerical simulations of statistically steady convection in a threedimensional porous medium are presented for Rayleigh numbers Ra 6 2 × 104. Measurements of the Nusselt number Nu in the range 1750 6 Ra 6 2× 104 are well fitted by a relationship of the form Nu= α3Ra+ β3, for α3= 9.6× 10−3 and β3= 4.6. This fit indicates that the classical linear scaling Nu∼ Ra is attained, and t...

BACKGROUND Cardiovascular magnetic resonance (CMR) steady state free precession (SSFP) cine sequences with high temporal resolution and improved post-processing can accurately measure RA dimensions. We used this technique to define ranges for normal RA volumes and dimensions normalized, when necessary, to the influence of gender, body surface area (BSA) and age, and also to define the best 2D i...

This article proposes to study the first 12 years of the Minas Gerais Radium Institute, founded in 1922. Its work in the fight against cancer in Brazil, albeit still little known, is coming to light as its institutional documents are studied. A database has been prepared using information from its patient register, based on which statistical analyses have been done to identify the types of canc...

We evaluated the antimicrobial activities of a cationic Gemini surfactant, trans-1,4-bis[2-(alkanoyloxy)ethyldimethylammonio]-2-butene dichloride [II-m-2(t-butene)] and its derivatives against Gram-positive and Gram-negative microorganisms. The II-m-2(t-butene) compound was previously shown to have good surface activity and biodegradability. A dodecanoyloxy derivative (m = 12) of II-m-2(t-buten...

BACKGROUND Antibodies against cyclic citrullinated peptide (anti-CCP) are considered to be specific for rheumatoid arthritis (RA). OBJECTIVE To assess the clinical significance of anti-CCP in a cohort of patients with juvenile idiopathic arthritis (JIA). METHODS Anti-CCP were tested by an enzyme linked immunosorbent assay (ELISA) in serum samples from 109 patients with JIA (30 boys, 79 girl...

OBJECTIVES We assessed the ability of anti-cyclic citrullinated peptide (CCP) tests to diagnose rheumatoid arthritis (RA), comparing the effect of manufacturer assay type, study design (single- and two-gated) and duration of disease (early vs. established). METHODS We searched seven databases for relevant diagnostic studies containing data on CCP tests in known or suspected RA patients. We us...

OBJECTIVE To investigate whether soluble interleukin-2 receptor (sIL-2R) could be a useful marker of disease activity in rheumatoid arthritis (RA); sIL-2R levels in serum and in synovial fluid were determined by enzyme-linked immunosorbent assay. METHODS Sixty five serum and 27 synovial fluid samples were obtained from patients with RA. Twenty five serum and 28 synovial fluid samples from pat...
