title: Open public spaces and physical activity facilities: study of systematic observation of the environment

description: Abstract The aim of this study was to investigate the quantity and quality of open public spaces (OPS) and physical activity (PA) facilities in Florianopolis, Santa Catarina. A descriptive survey was carried out in 2015 on the quantity, type and quality of OPS and PA facilities. The quality of OPS and PA facilities were assessed by systematic observation. A quality index of OPS (score -3 to 6 points) was divided into three categories, poor (category ≤0), average (0.1 to 2.9) and good quality (category ≥3). For analysis, descriptive statistics were used. Of the 214 OPS, the highest proportion was squares/gardens (n = 128, 59.8%). Of the 214 OPS, 59.8% were squares/gardens. About 51.9% (n = 111) of OPS had good quality. A higher proportion of comfort items obtained good quality, such as lighting (54.7%), trash cans (45.8%) and garden benches (55.1%). In more than 60.0% of OPS, there were no incivilities. Of the 377 PA facilities identified, 53.6% presented good quality and 13.8% poor quality. Playgrounds (29.4%), outdoor gyms (15.9%) and soccer fields/courts (14.9%) were more frequent, only the latter less than half had good quality (28,6%). There were no PA facilities in 29.0% of OPS. A higher proportion of OPSs have good quality, but less than half require improvement, comfort, less incivility and greater diversity of PA facilities. This may promote greater visits to OPS and leisure opportunities, including the practice of PA.

title: A rare case of gastric mucormycosis in an immunocompetent patient

description: Abstract We report the case of a 23-year-old immunocompetent patient who presented at the emergency department of a Brazilian hospital with epigastric pain and fever. After an investigation that included a computed tomography scan and upper gastrointestinal endoscopy with biopsy, a diagnosis of mucormycosis was established. The patient exhibited favorable progress after surgery and antifungal therapy. Mucormycosis is a rare condition that usually affects immunocompromised patients, with a high mortality rate of up to 85%. Correct diagnosis and fast initiation of therapy are required to ensure improved patient prognosis.

title: Social and Professional Profile and Territorial Distribution of Russians in São Paulo: Displaced Persons from Europe and Refugees from China after World War II

description: Abstract The aim of this article is to research the main characteristics of two Russian groups coming to the State of São Paulo after World War II: DPs from Europe and Russian refugees from China. To that end, data contained in the database on DPs in the State of São Paulo, consolidated by Salles et al. (2013), was systematized and analyzed. Research revealed that the Brazilian policy on admission of DPs as industrial workforce had direct impact on the profile of the Russian population selected to immigrate to Brazil, mainly moving to the capital of the State of São Paulo. Russian refugees from China had a different demographic and social profile; the group had the most women and children and employed predominantly in the service sector. The professional characteristics of these two groups determined their distribution in the districts of São Paulo. As Europe’s Russian DPs moved to peripheral and industrial districts, Russians from China settled in neighborhoods closer to the city center.

title: Caffeine in teas: levels, transference to infusion and estimated intake

description: Abstract Caffeine is naturally present in several foods, being one of the most consumed dietary ingredients in the world; however, excessive intake may cause health concerns. This study evaluated caffeine levels in teas and their infusions, the transference rate during brewing, and estimated caffeine intake from tea infusion. Brands and batches of 4 types of teas were analyzed for caffeine content by high performance liquid chromatography with a diode array detector. Mate tea was the one that presented lowest levels (6.1 to 13.2 mg/g) while Camellia sinensis teas were from 14.3 to 34.8 mg/g. There were statistical differences between different types, brands and batches. Caffeine levels in infusions followed the same pattern of the leaves, with mate tea presenting lowest levels. Caffeine percentage of transference from leaves to infusion varied from 51.5 to 85.2%. Caffeine intake was estimated to be up to 191.4 mg/day. Tea may be considered an important source of caffeine intake for heavy tea drinkers.

title: Thermal degradation kinetics of ascorbic acid, thiamine and riboflavin in rosehip (Rosa canina L) nectar

description: Abstract In this paper, the loss of L-ascorbic acid, thiamine and riboflavin in rosehip nectar with the heating periods (0, 5, 10, 15, 20 and 30 min) at temperatures ranging from 70 to 95 °C is analyzed and experimental results are presented. Firstly, dried rosehip fruits were processed to rosehip nectar and then thermal treatment is performed. Liquid chromatographic (HPLC) method was used for the analysis of the contents of L-ascorbic acid, thiamine and riboflavin and examined compounds are thoroughly separated within 25 min. During thermal processing, degradation of L-ascorbic acid, thiamine and riboflavin in rosehip nectar were fitted to a first-order reaction kinetic model. Arrhenius relationship was used for the description of temperature dependence of reaction. Activation energies for L-ascorbic acid, thiamine and riboflavin between 70 to 95 ºC were found to be 55.30, 36.38 and 37.15 kJ/mol, respectively. To the best of the author’s knowledge, due to lack of study on the thermal degradation of L-ascorbic acid, thiamine and riboflavin in rosehip nectar, this manuscript will be the first reported study to enable future analysis.

title: Experimental and Theoretical Study of Corrosion Inhibition of Mild Steel in 1.0 M HCl Medium by 2(-4( hloro phenyl-1H- benzo[d]imidazol)-1-yl)phenyl)methanone

description: The 2(-4(chloro phenyl-1H- benzo[d]imidazol)-1-yl)phenyl)methanone (CBIPM) was synthesized and tested as a corrosion inhibitor for mild steel in 1.0 M HCl solution using electrochemical and spectroscopy measurements. Results obtained showed that this compound has a good inhibition properties for mild steel corrosion in acidic medium which its inhibition efficiency value reaches 98.9 % at 10-3 M. So, the potentiodynamic polarization curves showed that the CBIPM has a mixed type inhibitor. In addition, it is shown that the obtained results were confirmed by the UV-vis spectroscopic measurements. It is found that the inhibitor forms a complex with Fe2+ ion. On the other hand, the experimental results were completed by quantum chemical calculations using DFT method at the B3LYP/6-31G* level of theory. It is found that the theoretical and experimental results are in good agreement.

title: Impact of stabilizers on the rheological properties of ice creams

description: Abstract The effect of the food hydrocolloids Guar gum, Locust bean gum (LBG) and Gelatin, as well as their mixtures (even carrageenan was used in all formulations – 0.035%), was studied on the rheological characteristics of ice cream formulations. A frequency sweep test, at low temperature (-8 °C), was performed to evaluate the elastic (G’) and viscous (G”) modulus. The ice cream produced using Gelatin and blend of Gelatin and LBG (0.09 and 0.18%) presented higher values of G’, which is an indicative of the presence of ice crystals and greater rigidity. The thermo-oscillatory rheometry was used to correlate the rheological properties and the characteristic of the ice creams (creaminess, sensory, melting). A temperature sweep test, from -10 to 5 °C was performed to evaluate changes in the structures of the products and their relationship with the sensory properties. For all formulations tested, it was observed, from -10 °C to -1 °C, a large decline in the elastic and viscous modulus due to the loss of interactions between the ice crystals, associated with their melting. After melting, the parameter G”, indicative of the creaminess of ice cream during consumption, showed a slight advantage to the ice creams produced with Guar gum alone and its blend with LBG.

title: Evaluation of the antioxidant potential of Copaifera multijuga in Ehrlich tumor-bearing mice

description: ABSTRACT Copaifera multijuga, commonly known as copaiba, is popularly used in the form of tea for various conditions due to the presence of antioxidant substances in its composition, which protect cells against damage caused by free radicals. Its oleoresin is also used as an anti-inflammatory and antitumoral agent. The present study investigated the antioxidant effect of the ethanolic extract of copaiba stem bark on Swiss mice inoculated with solid Ehrlich tumors. Mice were inoculated subcutaneously with 1x106 Ehrlich’s tumor cells and treated via gavage with ethanolic extract of copaiba for thirty days, with doses varying between 100 and 200 mg kg-1. Biochemical analyses of enzymatic antioxidants [superoxide dismutase (SOD), catalase (CAT), glutathione-S-transferase (GST)], non-enzymatic antioxidants [reduced glutathione (GSH) and ascorbic acid (ASA)], substances reactive to thiobarbituric acid (TBARS) and protein carbonylation (carbonyl) in different tissues were significantly affected. The extract administered at 200 mg kg-1 presented higher antioxidant capacity in the liver, increased CAT, GST, GSH and decreased TBARS, as well as increased CAT activity and protein carbonylation in brain tissue. The results showed that the copaiba extract was able to reverse the oxidative stress caused by solid Ehrlich tumor, probably due to the presence of antioxidant compounds, and had potential antineoplasic effect after a 30-day treatment.

title: Phenolic compounds from Virola venosa (Myristicaceae) and evaluation of their antioxidant and enzyme inhibition potential

description: ABSTRACT Virola venosa, popularly known in Brazil as ucuuba-da-mata, occurs naturally in the Amazon region and has potential to provide useful natural compounds, as already known for other Virola species. Therefore, the objective of this study was to determine the chemical composition of bark and leaf extracts of V. venosa, and to test the antioxidant capacity and α-glucosidase inhibition potential of their compounds. Polar extracts showed to be more active in both assays, therefore a bioactivity-guided fractionation was performed to identify the compounds that were responsible for the recorded activities. Using a combination of LC-MS/MS analysis and isolation with NMR identification, eight phenolic compounds were identified. Assays with pure compounds of the active fraction revealed that ferulic acid was the main contributor compound to the observed bioactivity in the crude extracts.

title: Comparison of FDTD and TDWP Methods for Simulating Electromagnetic Wave Propagation above Terrains

description: Abstract Researchers have always been in face of path loss calculation in different media for applications such as telecommunication link design. Wave propagation calculations in large spaces using the FDTD method is time-consuming and imposes a great computational burden. For this reason, to replace the classical FDTD method for wave propagation simulation and path loss calculation in large spaces, optimized methods, namely TDWP, have been provided. In this paper, the use of the TDWP method for wave propagation simulation and path loss calculation above a terrain is investigated. Longitudinal components of ground-waves are taken into account (including direct waves, ground reflections, and surface waves). Propagation space is longitudinally divided into smaller FDTD windows with finite length. The electromagnetic pulse travels through these windows from left to right to the desired point. But despite its capability in reducing computational burden and increasing processing speed, TDWP has lower precision in instantaneous field simulation and calculation of propagation coefficients, so that results obtained from FDTD and TDWP are clearly different. In this paper, some efficient methods are proposed, which yield an increase in method accuracy.

title: Quantitation of muscle pathology abnormalities in 18 patients with mitochondrial disorders

description: ABSTRACT INTRODUCTION: Mitochondrial disorders can lead to the accumulation of mitochondria in muscle fibers, as indicated by ragged red (RRF) or ragged blue fibers when stained with modified Gomori trichrome or succinate dehydrogenase (SDH+), respectively, and, absence of activity of cytochrome c oxidase, COX negative fibers (COX-). The combined COX-SDH stain (COMBO+) can reveal even more COX-deficient fibers. OBJECTIVE: To quantify RRFs, SDH+, COX-, and COMBO+ fibers in muscle biopsies with mitochondrial findings. MATERIAL AND METHODS: We retrospectively selected 18 muscle biopsies with mitochondrial abnormalities based on the Walker criteria (percentage of RRFs/COX- fibers, and clinical picture), and/or the Sleigh criteria (percentage of RRFs, SDH+, and COX- fibers). RESULTS: Females represented 83.3%, with a mean age of 38.6 years (5 months-70 years). Patients were diagnosed with chronic progressive external ophthalmoplegia (CPEO, 66.7%), proximal myopathy (22.2%), idiopathic hyperCKemia (11.1%), Kearns-Sayre syndrome (5.6%), mitochondrial encephalomyopathy with ragged red fibers and stroke-like episodes (5.6%), and a dystrophic pattern (5.6%). Some cases of CPEO were combined with proximal myopathy. The quantitative pathologic findings were: RRFs, 3.95% ± 3.17%; SDH+, 7.55% ± 6.1%; COX-, 10.9% ± 7.2%; COMBO+, 14.22% ± 12.79%. We found a slight variation in the diameter of muscle fibers, no necrosis or proliferative connective tissue, few fibers with internal nuclei, and some cases with fiber type grouping. CONCLUSION: Pathologic events, grouped in ascending order of frequency, were RRFs, SDH+ fibers, COX- fibers, and COMBO+ fibers. These data emphasize the importance of the COMBO technique in revealing occult COX deficiency in muscle fibers.
