title: Solubility, Porosity, Dimensional and Volumetric Change of Endodontic Sealers

description: Abstract The aim of this study was to evaluate physical properties of endodontic sealers (AH Plus, MTA Fillapex and Endofill), by conventional and micro-CT tests. Dimensional stability was evaluated after immersion of materials in distilled water for 30 days. Solubility and volumetric change were evaluated after 7 and 30 days of immersion in distilled water. Solubility was evaluated by means of mass loss and volumetric change was assessed by micro-CT. Porosity was evaluated under a microscope after 7 days of immersion in distilled water, and by using micro-CT after setting and immersion in distilled water for 7 and 30 days. Statistical analysis was performed by ANOVA and Tukey’s test with 5% significance level. MTA Fillapex presented the highest solubility (p&lt;0.05), showing values above the ISO/ADA recommendations. MTA Fillapex presented higher volumetric and dimensional changes, followed by Endofill and AH Plus (p&lt;0.05). Dimensional stability of the MTA Fillapex and AH Plus did not follow ISO/ADA standards. The highest total porosity was observed for MTA Fillapex (p&lt;0.05). Endofill had higher total porosity than AH Plus according to microscope evaluation (p&lt;0,05), and both sealers were similar in micro-CT assessment (p&gt;0,05). In conclusion, MTA Fillapex presented higher solubility, dimensional and volumetric change besides porosity compared to the other evaluated sealers. The assessed physical properties of sealers are related, and the different tests provided complementary data. Micro-CT is a valuable method for assessment of physical properties of endodontic materials.

title: Visual quality and waste of fresh vegetables and herbs in a typical retail market in Brazil

description: ABSTRACT Because of high perishability, leafy vegetables and fresh herbs are transported to the market soon after harvest. It is very likely that most of the damage due to inadequate handling at the farm and during transport will result in food discard only later in the retail market or in the household. Inadequate handling and marketing strategies in the store are expected to further contribute to waste. The study was designed to address the following questions: 1) what is the visual quality of leafy vegetables and fresh herbs received in the retail market; 2) what is the volume of discard of this produce in the retail market 3) what are the main causes of discard and 4) how these variables are influenced by the vegetable species, the suppliers and the stores evaluated. The study was conducted in 4 stores of a regional supermarket chain in Federal District, Brazil, for a period of 6 months. We evaluated: 1) number of produce items received and discarded; 2) visual quality of produce at reception and 3) cause of discard. The operations in each store were described based on observations and discussion with the store staff. When considering the sum of all produce, the discard (expressed as units per day and corrected for quantity purchased) was influenced by all the factors studied, namely store, supplier and day of the week. Delivery of produce with any signs of wilting and yellowing was negligible but produce with bruised and old leaves which should have been trimmed in the farm were frequent. Visual quality was important to determine shelf life and preference by the consumer but how important it was depended on other factors such as the vegetable or herb considered and the workflow in the store. The discard varied from 8.7% to 97.0% of the number of units purchased. Smaller waste volume was observed for spring onion, parsley, coriander, collard, leek and green leaf lettuce. Waste volume equal to or above 50% was observed for baby romaine lettuce, broad-leaved endive, wild chicory, mustard greens, sage and thyme. The vegetables and fresh herbs discard in the Brazilian retail market is in great measure the result of technological constraints together with bad management practices in the store. The implications of this situation for the definitions of food waste and food loss are discussed.

title: THE INFLUENCE OF DIFFERENT ELECTROLYTES ON SULFENTRAZONE DECHLORINATION BY IRON-NICKEL BIMETALLIC NANOPARTICLES

description: ABSTRACT Kinetic studies of sulfentrazone herbicide dechlorination by Fe/Ni nanoparticles were performed in the presence of different electrolytes such as: Cl-, SO42-, NO3-, Cu2+, Na+ and Zn2+. In the presence of Cl- and SO42- the reaction occurred efficiently, reaching approximately 100% of dechlorination after 30 minutes of reaction. In the presence of NO3- and Cu2+ ions the sulfentrazone dechlorination was significantly inhibited, because these ions tend to compete with the substrate for the electrons donated by Fe0. In the presence of Na+ ions, the dechlorination efficiency remained approximately 100%, however, this electrolyte provided an increase on the reaction rate, due to the increase of the ionic strength in the system. The Zn2+ ions has no influence on the dechlorination efficiency, but the reaction rate was reduced due to the formation of a protective layer formed by the sorption of Zn2+ ions on the surface of the nanoparticles.

title: Expressions of plasma cystatin C, D-dimer and hypersensitive C-reactive protein in patients with intracranial progressive hemorrhagic injury after craniocerebral injury, and their clinical significance

description: ABSTRACT Objective To investigate the expressions of plasma cystatin C (Cys-C), D-dimer (D-D) and hypersensitive C-reactive protein (hs-CRP) in patients with intracranial progressive hemorrhagic injury (IPHI) after craniocerebral injury, and their clinical significance. Methods Forty-two IPHI patients and 20 healthy participants (control) were enrolled. The severity and outcome of IPHI were determined according to the Glasgow Coma Scale and Glasgow Outcome Scale, and the plasma Cys-C, hs-CRP and D-D levels were measured. Results The plasma Cys-C, D-D and hs-CRP levels in the IPHI group were significantly higher than those in the control group (p &lt; 0.01). There were significant differences of plasma Cys-C, D-D and hs-CRP levels among different IPHI patients according to the Glasgow Coma Scale and according to the Glasgow Outcome Scale (all p &lt; 0.05). In the IPHI patients, the plasma Cys-C, D-D and hs-CRP levels were positively correlated with each other (p &lt; 0.001). Conclusion The increase of plasma Cys-C, D-D and hs-CRP levels may be involved in IPHI after craniocerebral injury. The early detection of these indexes may help to understand the severity and outcome of IPHI.

title: THERMOPHYSICAL PROPERTIES OF 1-ETHYL-3-METHYLIMIDAZOLIUM CHLORIDE SOLUTION FROM 293.15 TO 323.15 K

description: ABSTRACT Aqueous systems composed of ionic liquid make up a new alternative for use in processes involving the separation of biomolecules. The objective of this experiment was to obtain the thermo-physical properties of density, refractive index, electrical conductivity, molar volume, thermal expansion coefficient and apparent specific volume of the ionic liquid 1-ethyl-3-methylimidazolium chloride. The thermo-physical properties of aqueous solutions of this ionic liquid were measured as a function of the mass fraction w = (0.05, 0.125, 0.2, 0.275 and 0.35), temperature T = (293.15, 303.15, 313.15 and 323.15) K and pH = (7.5, 8.0 and 8.5). Models representing the combined effects between variables were fit since they are required for industrial applications where the physical parameters must be accurately calculated. Models representing the combined effects of the variables temperature, mass fraction and pH values of ionic liquid were adjusted and presented good fit.

title: Acute Response to Aerobic Exercise on Autonomic Cardiac Control of Patients in Phase III of a Cardiovascular Rehabilitation Program Following Coronary Artery Bypass Grafting

description: Abstract Objective: The aim of the present study was to investigate the acute response to aerobic exercise on autonomic cardiac control of patients undergoing coronary artery bypass grafting (CABG). Methods: The study sample consisted of eight patients (age: 58.6±7.7 years; body mass index: 26.7±3.5 kg.m2) who underwent a successful CABG (no complications during surgery and/or in the following weeks). To assess heart rate variability (HRV), participants remained in a supine position with a 30-degree head elevation for 20 minutes. Electrocardiographic signal (protocol with three derivations) was collected from 600 Hz sample rate to obtain beat-to-beat intervals (R-R interval). This assessment was performed before, after one hour and after 24 hours of the exercise session. All patients underwent a 35 minutes aerobic exercise session (AES) (low-moderate intensity) on the cycle ergometer. Results: Significant differences were found in the time domain, with positive changes in root mean square of successive RR interval differences (rMSSD) (ms) (parasympathetic component) (one [P=0.017] and 24 hours [P=0.007] post-session). In the frequency domain, we found a significant difference in high frequency (HF) (ms2) (parasympathetic component) (one hour [P=0.048] post-session). The low frequency (LF)/HF ratio (sympathetic and parasympathetic components with a predominance of the sympathetic component) reached statistical significance only 24 hours (P=0.018) post-session. Additionally, the largest effect size was observed only for the LF/HF ratio at one (d=-0.8) and 24 hours (d=-1.3) after one AES. Conclusion: The practice of (acute) aerobic exercise improved autonomic cardiac control in patients undergoing CABG.

title: THE CORDIAL BUREAUCRACY: THE IMPLEMENTATION OF THE INSTITUTIONAL SUPPORT STRATEGY IN THE NATIONAL PRIMARY HEALTH CARE POLICY

description: Abstract Thise article analyzes the role of the institutional supporters as individuals responsible for the conduction of public policies. Thus, it aims to understand the way in which institutional relationships are developed from the basis of the Brazilian State, through the establishment of relational dynamics among public agents, especially in the confrontation of complex issues regarding Brazilian federative relationships. The study was conducted at the General Coordination for Primary Health Care Management of the Primary Health Care Department of the Brazilian Ministry of Health. The research was based on qualitative epistemology, with the development of a documentary research, observation, in-depth interviews and focus groups between November 2015 and June 2017. The results enabled the identification of two structuring elements of the work of the supporters - ties to and knowledge of the territory -, which subsidize the development of a typology of the strategy of action developed and operated by the supporters, namely: application, adaptation, and cooperation. We concluded that the advancement in the implementation of the institutional support strategy was fundamentally made possible due to the relational and in-person dynamics among the individuals, and its results indicate concrete possibilities regarding the advancement in the guarantee of the right to health, in spite of the difficulties and contradictions that characterize Brazilian federalism.
