title: Effect of a resistance exercise program for sarcopenic elderly women: quasi-experimental study

description: Abstract Introduction: Resistance training is quoted as one of the best pathways to manage sarcopenia and progressive resistance training is supposed to improve muscle mass, strength and performance in older adults. Objective: The aim was to examine the impact of a progressive resistance exercise program (PREP) on muscle and function performance in sarcopenic community-dwelling elder women. Methods: Quasi-experimental study (pre - post intervention). Participated 18 sarcopenic community-dwelling elder women (65 years or older). PREP based on 75% of the participant’s maximum load (12/wk, 3 times/wk). Main outcome measures: muscle strength of knee extensors (isokinetic dynamometry), muscle mass (dual-x ray absorptiometry - DXA), functional performance (Short Physical Performance Battery - SPPB). Paired t-test was used to evaluate differences pre and post intervention. Results: Improvements on power (p = 0.01) and peak torque (p = 0.01) were observed when measured by the isokinetic dynamometer at low speed (60º/s). Improvements on DXA (pre PREP: 5.49 kg/m2 vs. post PREP: 6.01 kg/m2; p = 0.03) and SPPB scores (pre PREP: 9.06 vs. post PREP: 10.28; p = 0.01) were also observed. Conclusion: The PREP was able to improve muscle and functional performance in sarcopenic community-dwelling elder women. This program should be considered in clinical practice.

title: Effect of cilostazol in experimental model of degloving injuries in rat limbs

description: Abstract Purpose: To evaluate the effect of the cilostazol on the evolution of partially avulsed flaps, using experimental model of cutaneous degloving in rat limbs. Methods: A controlled and randomized experimental study was carried out in which the blood flow and the percentage of flap necrosis were evaluated. We compared the study group, which received cilostazol, and the control group, which received enteral saline solution in the postoperative period. The blood flow in the flap was evaluated through Laser Doppler flowmetry, and a planimetry using the IMAGE J® software was employed for the calculation of the area of necrosis. Results: Enteral administration of cilostazol was associated with a higher mean blood flow in all regions of the flap, with a statistically significant difference in the proximal and middle regions (p&lt;0.001) and a lower percentage of necrotic area in the flap (p&lt;0.001). Conclusion: Postoperative enteral administration of cilostazol increased blood flow and decreased the total area of necrosis of avulsed cutaneous flaps of rat limbs.

title: Brazilian regional differences and factors associated with the prevalence of cesarean sections

description: Abstract Introduction: Brazil presents high C-section prevalence rates. Several factors may be associated with such high rates. Objective: To observe and analyze factors associated with the prevalence of cesarean sections in Brazil, according to their occurrence in Brazilian regions. Methods: An ecological study, having C-section as the outcome, from 1990 to 2013, in Brazilian regions, using data from the Brazilian National Health Survey, 2013. Records of women in their reproductive period, aged between 18 and 49 years, were included, totaling a sample of 16,175 women. Descriptive and bivariate analysis was carried out with logistic regression. Results: The prevalence of cesarean sections in Brazil was 53.03%. Vaginal delivery was more prevalent in the North (52.74%) and Northeast (51.06%) regions, while C-section was more prevalent in the Southeast (59.32%), South (56.96%) and Midwest (61.48%) regions. Over the years, an increased probability of cesarean sections was observed, particularly in the following regions: Northeast (2.21 times more, CI95%: 1,42 - 3,46) and South (2.75 times more, CI95%: 1,44 - 5,23). Women with higher levels of education are 2.05 times (CI95%: 1.27 - 3.30) more likely to have a C-section, especially those in the Northern and Southern regions. In the Northeast, this probability increased, regardless of the level of education. Conclusion: The prevalence of cesarean sections in Brazil is high and, over the years, factors such as level of education, maternal age and having health insurance, seem to contribute to the increase in surgical deliveries.

title: Annealing Effects on the Structural and Optical Properties of ZnO Nanostructures

description: ZnO nanostructures were synthesized by a proteic sol-gel method, using zinc nitrate hexahydrate and gelatin as precursors. Size and shape evolution of ZnO nanostructures were achieved by annealing temperature in the range 250-1000 ºC. The crystalline structure, morphology and optical properties of the ZnO nanoparticles were characterized by X-Ray Diffraction (XRD), Raman Spectroscopy (RS), Fourier Transform Infrared Spectroscopy (FTIR), Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM), and room temperature Photoluminescence (PL). The result of structural characterization shows the formation of platelets and nanorods in the micro-scale and ZnO nanostructures with high quality hexagonal wurtzite crystal. Sharp peaks in RS after annealing temperature, related to wurtzite structure, were observed corroborating with XRD and TEM measurements. Room temperature PL spectra showed two contribution bands which peaked at ~380 nm, originating from the recombination of free excitons, and ~520 nm corresponding to the impurities and structural defects, like oxygen vacancies and zinc interstitial. The effects of annealing temperature in the structural and optical properties are detailed and the results compared among the experimental techniques. The high quality of the samples obtained by an alternative organic precursor method opens a low-cost route to technological applications of zinc oxide.

title: Alternative control of post-harvest diseases in Tainung 1 papaya

description: ABSTRACT Controlling post-harvest papaya diseases without using agrochemicals is a challenge for producers. This study aimed at evaluating the effect of clove essential oil, biological fungicide (Trichodermil®), resistance inducer (Cob Sistem®) and chemical fungicide (Imazacure®) on the in vitro control of phytopathogenic fungi isolates from papaya as well as on the post-harvest quality of Tainung 1 papaya. The in vitro experiment was conducted in a complete randomized design, with five fungal species x five treatments and five replications. The in vivo experiment was conducted in a complete randomized design, with five treatments x five storage times, five replications and three fruits per replication. The fruits were stored under refrigeration at 10 ± 2 ºC and 90 ± 5 % of relative humidity and evaluated at 0, 7, 14, 21 and 28 days of storage, plus two shelf life days at 25 ± 2 ºC, to simulate marketing conditions. The inhibition of mycelial growth was evaluated in the in vitro experiment, while the diseases occurrence and post-harvest quality of the fruits were evaluated in the in vivo experiment. The clove essential oil and Trichodermil® were as efficient as Imazacure® in inhibiting the mycelial growth of Alternaria sp., Colletotrichum gloeosporioides and Rhizopus sp. The treatments with clove essential oil, Trichodermil® and Imazacure® were similar in controlling the pathogens up to 21 days of storage. The treatments had no effect on the fruits soluble solid contents.

title: Spray Deposited Nanostructured CuO Thin Films: Influence of Substrate Temperature and Annealing Process

description: In this study, CuO thin films were deposited on glass substrates at a wide range of temperatures from 450ºC to 550ºC with steps of 25ºC by chemical spray pyrolysis technique. Aiming to investigate the effect of annealing process, one of the resulting films was annealed at 450ºC for 3 hours under ambient air. Based on X-ray diffraction, all the resulting films are monoclinic with two prominent peaks at ~36º and ~39º. The crystallite size of the CuO film deposited at 450ºC was found to be the largest in comparison with the others. As the substrate temperature increased, a gradual change was observed for the CuO thin film surface morphology and in the case of annealed film, the grains and their boundaries became indistinguishable. The resistivity of the films was reduced by virtue of increasing the substrate temperature and also, both the mobility and carrier concentration of the annealed film were improved drastically after annealing. As expected, the CuO thin films absorption was considerable in the visible region and gradually declined after 800nm. The estimated band gap value of the CuO film deposited at 450ºC were fairly close to the optimum band gap for solar applications.

title: Phytoplankton in the central region of Paranoá Lake, Federal District of Brazil: an ecological and sanitary approach

description: ABSTRACT This study aimed at analyzing the dynamic, the structure and the sanitary importance of phytoplankton in a vertical profile at Paranoá Lake central region, Federal District, Brazil. Sampling was carried out monthly from October 2009 to September 2010, in six depths. Three distinct phases were identified, concerning mixing pattern: stratification (October 2009 to May 2010), mixing in (June to September 2010), transition (September 2010). Total phosphorus and soluble reactive phosphorus concentrations and algal biomass were relatively low, classifying Paranoá Lake as an oligotrophic reservoir. In opposite, total nitrogen nd functional groups were typical of mesotrophic environments. Altogether, 94 phytoplanktonic taxa were found, among 10 taxonomic classes, especially centrales diatoms, chlorophyceans and cyanobacteria. Thirteen functional groups were identified, with emphasis on C, J, F, X2, K and S1. During mixing and transition months there was an increase in diatom biomass (group C). On the vertical profile, there was a trend of K and S1 groups to locate at surface layers during warmer months. Considering the sanitary approach, this study reported algal taxa that can potentially promote odor and taste in the water (e.g., diatoms, cryptophytes, cyanobacteria) or cause filter clogging at water treatment plants (e.g., diatoms). Moreover, cyanobacterial taxa (e.g., Aphanocapsa and Planktolyngbya) were reported under densities that already point out the need of monitoring intensification and cyanotoxin analysis, according to the MS Ordinance number 2,914/2011.

title: Pulmonary paracoccidioidomycosis: a case report of reactivation in a patient receiving biological therapy

description: Abstract Paracoccidioidomycosis is an endemic disease in Latin America that is rarely associated with immunosuppression and biological therapy. Herein, we report for the first time a case of pulmonary paracoccidioidomycosis reactivation after infliximab treatment. A 47-year-old man from Brazil received infliximab to treat psoriatic spondyloarthropathy and presented with cough, dyspnea, weight loss, and fever. Chest computed tomography revealed a pulmonary nodule and biopsy confirmed paracoccidioidomycosis. Treatment with sulfamethoxazole and trimethoprim was initiated for fungal infection and infliximab was reintroduced two months later. Considering his clinical improvement and favorable radiologic evolution, antifungal therapy was discontinued after 29 months.
