3. Rotational thromboelastometry assessment of ballanced crystalloid, hydroxyethyl starch and gelatin effects on coagulation: a randomized trial
Resumo Justificativa e objetivos Os cristaloides e coloides modernos são soluções balanceadas e cada vez mais utilizadas no período perioperatório. No entanto, não há estudos que avaliem seu efeito negativo na coagulação do sangue total e o intenso debate sobre a solução que cause um efeito mínimo na coagulopatia permanece. O objetivo de nosso e

4. Characterization of Ti-35Nb alloy surface modified by controlled chemical oxidation for surgical implant applications
ABSTRACT Titanium-Niobium alloys have been studied for biomedical applications due to their satisfactory biocompatibility. In order to improve the long-term implantation, surface modification techniques have been developed to generate suitable topography, roughness, chemical composition, surface energy, etc. Considering this approach, the present work aimed

5. ADIPONECTIN, VITAMIN D AND NUTRITIONAL STATUS IN PATIENTS WITH ADVANCED COLORECTAL CANCER OR DURING FOLLOW-UP
RESUMO CONTEXTO: Considerando a alta incidência de óbitos devido ao câncer coloretal (CCR), estudos investigaram variáveis que podem afetar a sobrevida, com objetivo de prolongar a sobrevida. O estado nutricional desses pacientes também pode predizer a sobrevida. OBJETIVO: O objetivo do presente estudo foi avaliar se o índice de massa corporal (IMC

6. Droplet Size Distribution in Water-Crude Oil Emulsions by Low-Field NMR
This paper reports the droplet size distribution (DSD) measurements in 28 W/O (water/oil) crude oil emulsions prepared with two Brazilian oils (medium and heavy) under different shear conditions using both 10 g L-1 NaCl solution and water production by low field nuclear magnetic resonance (NMR, 2.2 MHz). The PFGSTE (pulsed-field gradient-stimulated echo) pul

7. The influence of nitrogen to hydrogen ratio and temperature on thickness and phase composition in plasma nitrided Ti-6Al-4V
ABSTRACT Ti-6Al-4V was plasma nitrided using several N2/H2 ratios and substrate temperatures. In order to investigate the combined influence of these parameters on phase composition and thickness of the coatings, the phases in the as received, annealed, and nitrided Ti-6Al-4V samples were identified with Rietveld refinement. In the as-received and annealed s

8. Effects of artepillin C on model membranes displaying liquid immiscibility
It has been hypothesized that the therapeutic effects of artepillin C, a natural compound derived from Brazilian green propolis, are likely related to its partition in the lipid bilayer component of biological membranes. To test this hypothesis, we investigated the effects of the major compound of green propolis, artepillin C, on model membranes (small and g

9. Adductor Pollicis Muscle Thickness as a Marker of Nutritional Status in Heart Failure
Abstract Background: Malnutrition is associated with morbidity and mortality in patients with heart failure (HF). Thus, it is essential to apply reliable indicators to assess the nutritional status of these individuals. Objective: To evaluate the thickness of the adductor pollicis muscle (APM) in patients with HF as an indicator of somatic protein status a

10. Efectos de tratamientos térmicos post-alcalinos sobre las propiedades superficiales de titanio para implantes dentales con diferentes recubrimientos
ABSTRACT Titanium is widely used as dental implant since it is bio-inert and osseointegratable. However, provided that this material cannot induce bone growth from its surface, it is usual to carry out different surface treatments in order to develop bioactive coatings that increase both the initial rate of bone development and the biological anchorage of im

11. Cell and Bacteria-Baterial Interactions on the Ti10Mo8Nb Alloy After Surface Modification
The purpose of this study is the surface modification of Ti10Mo8Nb experimental alloy by using TiO2 nanostructure growth. Ingots of the Ti10Mo8Nb experimental alloy were produced by fusion from sheets of molybdenum, niobium, and titanium commercially pure in an arc melting furnace under argon atmosphere. The potentiostatic anodic oxidation was performed usin

12. Water Permeability Increase in Ultrafiltration Cellulose Acetate Membrane Containing Silver Nanoparticles
Inorganic nanoparticles incorporation in polymer membranes for filtration processes has attracted the attention of researchers in order to improve in some ways their performance. In this work, AgNPs were synthesized "in situ" in cellulose acetate (CA) membrane by chemical reduction of a silver salt. The membranes were prepared by the nonsolvent induced phase
