title: Acute effects of intradialytic aerobic exercise on solute removal, blood gases and oxidative stress in patients with chronic kidney disease

description: Abstract Introduction: Hemodialysis contributes to increased oxidative stress and induces transitory hypoxemia. Compartmentalization decreases the supply of solutes to the dialyzer during treatment. The aim of this study was to investigate the acute effects of intradialytic aerobic exercise on solute removal, blood gases and oxidative stress in patients with chronic kidney disease during a single hemodialysis session. Methods: Thirty patients were randomized to perform aerobic exercise with cycle ergometer for lower limbs during 30 minutes with intensity between 60-70% of maximal heart rate, or control group (CG). Blood samples were collected prior to and immediately after exercise or the equivalent time in CG. Analysis of blood and dialysate biochemistry as well as blood gases were performed. Mass removal and solute clearance were calculated. Oxidative stress was determined by lipid peroxidation and by the total antioxidant capacity. Results: Serum concentrations of solutes increased with exercise, but only phosphorus showed a significant elevation (p = 0.035). There were no significant changes in solute removal and in the acid-base balance. Both oxygen partial pressure and saturation increased with exercise (p = 0.035 and p = 0.024, respectivelly), which did not occur in the CG. The total antioxidant capacity decreased significantly (p = 0.027). Conclusion: The acute intradialytic aerobic exercise increased phosphorus serum concentration and decreased total antioxidant capacity, reversing hypoxemia resulting from hemodialysis. The intradialytic exercise did not change the blood acid-base balance and the removal of solutes.

title: Cardinal temperatures for planting-emergence phase in gladiolus

description: ABSTRACT: The objective of this study was to determine the cardinal temperatures for the planting-emergence phase of gladiolus. A controlled environment experiment was performed in a growth chamber in the Universidade Federal do Pampa - Campus Itaqui, using the completely randomized experimental design with 12 temperature treatments (5°C, 7°C, 10°C, 13°C, 16°C, 18°C, 20°C, 22°C, 25°C, 30°C, 33°C, 35°C) and ten replicates. Corms of the cultivar ‘Amsterdam’ were planted at a depth of 10cm in 1.7dm3 pots. Every day the date of emergence of the gladiolus plants was observed. Then for each treatment, the emergence rate was calculated as the inverse of the duration of the budding phase, and estimated data were achieved employing the non-linear model of simulation. The lower base and upper base temperatures were identified at the non-emergence temperatures. To estimate the optimum temperature, the root of mean square error was used. Between 22 and 25ºC the planting-emergence phase was reported to be completed in a shorter time span, although the smaller root mean square error was achieved at 22.5ºC. The cardinal temperatures of the planting-emergence phase of gladiolus, lower base, optimum and upper base temperature were 5°C, 22.5°C and 35°C, respectively.

title: Analysis of Compositional Modification of Commercial Aluminum Bronzes to Obtain Functional Shape Memory Properties

description: In copper-based shape memory alloys (SMAs), some exceptional phenomena, such as the shape memory effect (SME) or superelasticity (SE), are observable. However, commercial aluminum bronzes, Cu3Al-based alloys, do not present these functional properties (SME and/or SE) in their original state. Thus, since one of the main copper-based SMA systems is the Cu-Al-Ni alloy, this paper aims to analyze the modification of these commercial aluminum bronzes to SMA by the addition small amounts of Cu, Al and/or Ni. These modified bronzes were reprocessed by induction melting and injected by centrifugation into a ceramic coating mold. The modifications were made to determine the nominal composition for a Cu-13,0Al-4,0Ni (%wt) SMA. The effectiveness of the modifications was verified by differential scanning calorimetry (DSC) thermal analysis. All modified Cu-Al-Ni bronzes presented DSC peaks of the thermoelastic martensitic phase transformation, showing that SMA behavior was achieved, while the non-modified bronzes revealed no transformation. These results were supported by Vickers hardness (HV), X-ray diffraction (XRD), semi quantitative composition by EDS analysis and optical microscopy.

title: ECAS A-B-C: alternate forms of the Edinburgh Cognitive and Behavioural ALS Screen

description: <i>Background</i>: The Edinburgh Cognitive and Behavioural ALS Screen (ECAS) is a short assessment by which neuropsychological symptoms can be detected and quantified in people with ALS. To avoid potential practice effects with repeated administration, here we present alternative versions of the ECAS suitable for measuring change over time. <i>Objective</i>: To develop two alternate versions of the ECAS: ECAS-B and ECAS-C. <i>Method</i>: One hundred and forty-nine healthy adult participants were recruited. Thirty participants completed a pilot study in developing the alternate versions. Two groups of 40 participants were administered the ECAS-B or ECAS-C and compared to published data of the original ECAS (ECAS-A) to determine equivalence. An additional 39 participants were administered the ECAS consecutively, either repeating the original version (ECAS-A-A-A) serially or the different versions (ECAS-A-B-C) to determine potential practice effects. Recordings of assessments were scored by a second researcher to determine inter-rater reliability. <i>Results</i>: No significant differences were found between versions (A, B, C) of the composite performance measures of ALS Specific, ALS Non-Specific, and ECAS Total scores. Repeated serial administration of ECAS-A (A-A-A) produced some practice effects for composite scores, whereas no such effects were found when alternate versions were administered serially (A-B-C). Exceptionally high intra-class correlations were found for all three versions of the ECAS suggesting a high degree of rater agreement. <i>Conclusion</i>: The newly developed alternate forms of the ECAS are both highly equitable to the original ECAS-A and enable avoidance of practice effects, thus supporting their use in measuring cognition and behaviour over time.

title: Therapeutic effects of intensive voice treatment (LSVT LOUD<sup>®</sup>) for children with spastic cerebral palsy and dysarthria: A phase I treatment validation study

description: <i>Purpose</i>: The aim of the present study was to validate and extend the evaluation of treatment outcomes following LSVT LOUD® in children with dysarthria secondary to cerebral palsy (CP). <i>Method</i>: Seven children (5 females, 6–10 years) with spastic quadriplegia and dysarthria received LSVT LOUD. Outcomes included: (<i>a</i>) quantitative and qualitative indices of communication and social functioning representing therapeutic effects and (<i>b</i>) features of the acoustic signal representing physiological effects on the speech mechanism. A matched group of typically developing children served as controls. Testing occurred just prior to (<i>PRE</i>), immediately following (<i>POST</i>), and at 12 weeks post-treatment (<i>FUP</i>). <i>Result</i>: Expert listeners preferred voice quality and articulatory precision of children with CP at <i>FUP</i> as compared to <i>PRE</i>. Acoustic data indicated improvements on select measures of vocal functioning at <i>POST</i> with some maintenance at <i>FUP</i>. Single word intelligibility improved immediately <i>POST</i>, but was not maintained at <i>FUP</i>. Parents rated positive changes in characteristics of voice and speech and qualitative changes in communication at both <i>POST</i> and <i>FUP</i>. <i>Conclusion</i>: The present study validated some of the previous LSVT LOUD outcomes in children with dysarthria and CP and extended our understanding of therapeutic effects through qualitative data obtained from extensive parent interviews.

title: Supplementary Material for: In vivo Effects of Repeated Thyronamine Administration in Male C57BL/6J Mice

description: <b><i>Objectives:</i></b> Thyronamines are decarboxylated and deiodinated metabolites of thyroid hormones (THs). Of all possible thyronamine variants, only 3-iodothyronamine (3-T<sub>1</sub>AM) and iodine-free thyronamine (T<sub>0</sub>AM) have been detected in vivo. While intensive research has been done on the (patho-)physiological action of 3-T<sub>1</sub>AM, the role of T<sub>0</sub>AM has been studied less intensively. <b><i>Study Design:</i></b> We determined whether a single pharmacological dose (50 mg/kg, i.p.) or repeated administration (5 mg/kg/day, i.p., for 7 days) of T<sub>0</sub>AM affects metabolism, cardiovascular function, or thermoregulation in male C57BL/6J mice. Since selenium (Se) is important for proper TH function and Se metabolism is affected by TH, we additionally analyzed Se concentrations in liver, serum, and kidney using total reflection X-ray analysis. <b><i>Results:</i></b> A single injection of T<sub>0</sub>AM had no effect on heart rate, temperature, or activity as assessed by radio telemetry. Likewise, daily administration of T<sub>0</sub>AM did not alter body weight, food or water intake, heart rate, blood pressure, brown adipose tissue thermogenesis, or body temperature, and no significant differences in hepatic glycogen content or mRNA expression of genes involved in cardiovascular function or metabolic control were determined. Also, the X-ray analysis of Se concentrations revealed no significant changes. However, hepatic T<sub>0</sub>AM was significantly increased in the treated animals. <b><i>Conclusions:</i></b> In summary, our data demonstrate that T<sub>0</sub>AM elicits no obvious metabolic, cardiovascular, or thermoregulatory activities in mice. As T<sub>0</sub>AM does also not interfere with TH or Se metabolism, we conclude that the deiodination of 3-T<sub>1</sub>AM to T<sub>0</sub>AM constitutes an efficient inactivation mechanism, terminating the actions of the more powerful precursor.

title: Fields in organization studies: relational approaches?

description: Abstract: This paper analyzes how different approaches of organizational analysis use the notion of ‘field’. The philosophical grounds and proposals that motivated the usage of this concept in the social sciences, associated to a specific relational approach illustrated by the sociological approach of Bourdieu, are taken as a reference. Identifying the genesis and paying particular attention to the configuration of scientific concepts in this approach, theoretical tools of sociological institutionalism in organizational analysis and the strategic action field approach are discussed. The paper concludes that overcoming limitations commonly associated to neoinstitutionalism involves reconfiguring its conceptual tools. A broader and more flexible concept of field, intrinsically articulated with conceptions of action and power, is considered to be particularly relevant.

title: Post-harvest characterization of sweet corn submitted to nitrogen fertigation

description: Abstract The aim of this research was evaluate the quality of sweet corn submitted to the nitrogen nutrient installment process applied by fertigation from the physical, chemical and sensory parameters. The cultivar of sweet corn used in the experiment was Doce Cristal (BR-402), submitted to the influence of fertigation in 4 treatments with different installments of ammonium nitrate: Treatment 1: 2 applications, Treatment 2: 4 applications, Treatment 3: 6 applications and Treatment 4: 8 applications. The corn cobs were evaluated for the physical parameters of length, diameter and mass; the physicochemical parameters of pH, soluble solids, moisture and ash; and a sensory analysis using the acceptance test as well as the instrumental texture analysis. For the physical parameters, the treatments only affected the diameter of the ears with (5.3 cm to 5.8 cm) and without (4.3 cm to 4.7 cm) the straw. In the physicochemical analysis only titratable acidity measured as malic acid did not differ between treatments, and the soluble solids showed the greatest difference between treatments with treatment 4 presenting 15 ºBrix and treatment 2 17 ºBrix. The treatments did not influence the sensory acceptance of the sweet corn cobs, which showed good acceptability for all attributes evaluated, with average hedonic scores greater than 7.3.
