title: THE EFFECT OF EXERCISE ON INTERFERON GAMMA, BODY FAT AND BMI OF KIDNEY TRANSPLANT PATIENTS

description: ABSTRACT Introduction: Poor physical function and obesity are well documented in kidney transplant patients. Significant health benefits result from regular physical activity, many of which are important for kidney transplant patients. Objective: The aim of this study was to investigate the effects of 10-week combined exercises on Interferon Gamma (IFNγ), body fat percentage (BF%) and body mass index (BMI) in kidney transplant patients. Method: In a randomized controlled experimental design, 44 kidney transplant patients aged 20-50 years were randomly divided into two groups of exercise (n=23) and control (n=21). The exercise group participated in a cumulative training program for 10 weeks, three days a week, 60–90 minutes per day at 40-65% of predicted maximal heart rate reserve. A 5 ml venous blood sample and anthropometric parameters were taken from the subjects at baseline and after 10 weeks. Results: The exercise group showed an improvement in BF% (from 31.80±5.64 to 28.86 ± 5.82, p =0.001) and BMI (from 26.23 ± 1.81 to 25.45 ± 2.11, p = 0.001), but there was no significant change in the IFNγ level (from 0.06 ± 0.02 to 0.06 ± 0.02, p = 0.829). There was a significant difference between the control and exercise groups for BF% (p = 0.001) and BMI (p = 0.001). Conclusion: As a take-home message, it should be mentioned that combined exercise intervention is inexpensive and portable and can be performed at home or health centers for kidney transplant patients to reduce their weight and BF%. Evidence Level I; High quality randomized trial with or without statistically significant difference, but with narrow confidence intervals.

title: Anticorrosive Effect of PVP 40000 Against AISI 1020 Carbon Steel in HCl

description: Polymers have received considerable attention for replacing synthetic inorganic and organic anti-corrosion inhibitors since they are not as toxic for the environment, besides being cheaper. Polyvinylpyrrolidone (PVP) has been studied due to its applicability, solubility, very low toxicity, cost and efficiency in corrosion inhibition against metals, such as zinc, aluminum, stainless steel, and others. Its anti-corrosion activity with 40000 g mol-1 was tested against AISI 1020 carbon steel in 0.5 mol L-1 HCl, and evaluated by electrochemical techniques: Potentiodynamic Polarization (PP), Linear Polarization Resistance (LPR), and Electrochemical Impedance Spectroscopy (EIS). The maximum efficiency was 90% and 89% in EIS and LPR, respectively, at concentration of 1.0 x 10-7 mol L-1. The adsorption mechanism was coherent with Langmuir isotherm model. The morphology of the corroding carbon steel surface, in the presence and absence of the PVP, was visualized using Scanning Electron Microscopy (SEM).

title: Water Stress in the Production and Quality of Bidens pilosa and Raphanus raphanistrum Seeds

description: ABSTRACT: Plants in soils with low water availability may present a reduction of their leaf area and photosynthetic rate, as well as lower assimilated compound supply for seeds. Knowing the physiological quality and seed production of weeds generated under water deficit conditions can help understanding the survival and competition strategies of species. The objective of this work was to evaluate the effect of water stress on the production and germination of Bidens pilosa and Raphanus raphanistrum seeds. Plants were maintained in soils with different water potentials (-0.03, -0.07 and -1.5 MPa) throughout their cycle, until seed production, when they were harvested. Then, evaluations were performed to find out the number of seeds per plant and number of seeds per pod (Raphanus raphanistrum). The evaluation on the germination of these seeds was performed on moistened paper, with four replications, at 20-35 oC and 8 hours of light per day, weekly, until 28 days after seeding. The experimental design was completely randomized with three treatments (soil water potential: -0.03 MPa, -0.07 MPa and -1.5 MPa). The results were submitted to analysis of variance by F test, and the means of the treatments were compared by Tukey’s test at 5% probability. It was concluded that Bidens pilosa is more adapted to water deficit conditions than Raphanus raphanistrum, due to the higher production of seeds, better germination and seedlings with greater vigor.

title: Multimodal Architecture in Geoinformation Cartographic Communication Process

description: ABSTRACT The search for relevance is a basic feature of human cognition. Whereas the interval between the construction and the use of maps is a communication process, geosciences professionals can explore the relevance of the search condition to better serve the needs of many users maps. This article is based on debate to what extent the relevance theory and approach of Multimodality may contribute to the increased use of maps, based on the principle of least effort and multimodal speech in the communication process. The objective is to discuss the validity of the identification of a set of modes involved in the production (experts) and use (user) so that the geoinformation maps meet relevant requirements, and hence are more useful. To accomplish this, the article presents an experiment using elements of geoinformation, the relevance theory and Multimodality. In the final considerations, it presents further study possibilities.

title: Comparison of Cellulose Extraction from Sugarcane Bagasse Through Alkali

description: This article investigated the cellulose obtained from sugarcane bagasse by five different extraction mercerization methods. The comparison of the methods gives a clearer picture of that is more effective and feasible for production of SCB cellulose. All the celluloses were characterised by X-Ray Diffraction (XRD), Fourier Transform Infrared (FT-IR), Thermal Gravimetric Analysis (TGA), Scanning Electron Microscope (SEM) and Optical Microscope (OM). All the methods led to white material resembling pure cellulose due to removal of non-cellulosic constituents as can be seen by disappearance of aromatic bands. The removal indicated a decrease in diameter and improved thermal stability in most methods. The materials in general stand a better chance of competing as fillers for polymeric composites.

title: Genotype-environment interaction on the density of peach buds cultivated in a humid subtropical climate

description: Abstract Studies on the interaction of genetic and environmental effects on floral morphogenesis in peach trees grown in humid subtropical climate provide important information related to adaptation and for assisting in the selection of new cultivars. This study aimed to verify the genetic and environmental effects and to identify peach tree genotypes with greater shoot length, vegetative bud, flower bud density adaptability and stability under humid subtropical climate conditions. Twelve peach tree genotypes were evaluated over a period of eight years, during the growing season (2006/07 to 2013/14) in Pato Branco-PR, Brazil. Data were collected for shoot length (SL), flower bud density (FBD) and vegetative bud density (VBD), as well as temperature, humidity and precipitation. For the analysis of adaptability and stability we used GEE Biplot methodology. SL was influenced by the temperature and relative humidity. Increased exposure time to temperatures below 20 °C and above 30 °C, high thermal amplitude and relative humidity of less than 50% reduced shoot growth. VBD and FBD were predominantly controlled by the genetic factor. For VBD, the genotypes ‘Cascata 1055’ and ‘Conserva 681’ were the most adapted. For FBD, the genotypes ‘Cascata 1055’, ‘BRS Bonão’, ‘Conserva 681’, ‘Cascata 967’ and ‘BRS Kampai’ presented better adaptability. The genotypes more adapted to the FBD can be recommended for cultivation in the humid subtropical climate, since they also present greater stability in the production of fruits, independently of the meteorological conditions that occur during the vegetative and reproductive season.

title: Repeatability based on growth behavior ofjabuticabeira tree genotypes

description: Abstract The aim of this study was to estimate the coefficients of repeatability and determination and the minimum number of evaluations able to provide certainty levels of prediction of the real value of these individuals through stem length and the length of primary shoots in 29 jabuticabeira genotypes. The stem length and the primary shoots were evaluated between July 2012 and June 2015, representing three growth cycles. The determination of the repeatability coefficients, determination coefficients and the number of measurements required to predict the genotypes true value were performed by multivariate principal component methods based on the variance and phenotype covariance matrix. The repeatability and determination coefficients obtained are relevant for the growth traits of jabuticabeira tree genotypes evaluated. With the three evaluations carried out, it is possible to select the jabuticabeira tree genotypes with 95% accuracy for a variable stem length and with 85% for the variable shoots length, but for the same level of significance would still require 5 more evaluations.

title: Fasting/Refeeding Cycles Prevent Myocardial Dysfunction and Morphology Damage in the Spontaneously Hypertensive Rats

description: Abstract Background: Caloric restriction is known to impair the cardiac function and morphology in hypertrophied hearts of spontaneously hypertensive rats (SHR); however, the influence of fasting/refeeding (RF) is unknown. Objective: To investigate the fasting/refeeding approach on myocardial remodeling and function. In addition, the current study was designed to bring information regarding the mechanisms underlying the participation of Ca2+ handling and b-adrenergic system. Methods: Sixty-day-old male SHR rats were submitted to food ad libitum (C), 50% food restriction (R50) or RF cycles for 90 days. Cardiac remodeling was assessed by ultrastructure analysis and isolated papillary muscle function. The level of significance considered was 5% (a = 0.05). Results: The RF rats presented lower cardiac atrophy than R50 in relation to C rats. The C rats increased weight gain, R50 maintained their initial body weight and RF rats increased and decreased weight during RF. The RF did not cause functional impairment because the isotonic and isometric parameters showed similar behavior to those of C. The isotonic and isometric cardiac parameters were significantly elevated in RF rats compared to R50 rats. In addition, the R50 rats had cardiac damage in relation to C for isotonic and isometric variables. While the R50 rats showed focal changes in many muscle fibers, the RF rats displayed mild alterations, such as loss or disorganization of myofibrils. Conclusion: Fasting/refeeding promotes cardiac beneficial effects and attenuates myocardial injury caused by caloric restriction in SHR rats, contributing to reduce the cardiovascular risk profile and morphological injuries. Furthermore, RF promotes mild improvement in Ca2+ handling and b-adrenergic system.

title: Soil management and ionic strength on selenite retention in oxidic soils

description: ABSTRACT Sorption of selenium (Se) on soils may be influenced by factors that are changed though agricultural practices usually performed for crop production, such as soil pH, competing anion and organic matter contents, among others. This study aimed to evaluate the influence of soil management and ionic strength (IS) on Se retention in Brazilian soils, which is important to predict Se availability in both systems, native and cultivated soils. For that, adsorption and desorption reactions of Se were evaluated in 16 soil samples (eight from cultivated soils and eight from native soils), using solutions containing 100 and 500 µg L-1 Se in the form of sodium selenate and in two IS, 15 and 150 mM. Se adsorption varied as a function of IS for most soils, which may indicate that the adsorption mechanism by outer-sphere complex is important for selenate retention in the studied soils, but future studies involving other techniques, such as spectroscopic studies, are needed to more clearly confirm the adsorption mechanism. In general, adsorption varied in relation to soil characteristics, and native soils adsorbed larger Se amounts than the cultivated soils. In terms of desorption, soils which had larger Se adsorbed amounts also presented larger desorbed amounts. Finally, IS and soil management influenced the availability of selenate in the studied soils.
