title: Ultrasonic-extraction of phenolic compounds from Phyllanthus urinaria: optimization model and antioxidant activity

description: Abstract Ultrasonic-assisted extraction technique was used to extract phenolic compounds from Phyllanthus urinaria and response surface methodology was used to optimize the extraction parameters including ultrasonic time (X1), ethanol concentration (X2) and solid-liquid ratio (X3). A mathematical model of the tree parameters for the high extraction yield (Y) was established. Antioxidant activity of the phenolic compounds was investigated by DPPH free radicals, ABTS free radicals, hydroxyl free radicals and reducing power assay with vitamin C as a control. The results showed that the independent variables (X1, X2 and X3) and the interaction terms (X1X3 and X2X3) had a significant effect on the extraction yield. The effect of the variables on the extraction yield was in the order of X3, X1 and X2. The optimal extraction process was X1 of 34 min, X2 of 46.5% and X3 of 1:63 g/mL, and the extraction yield was 9.59%, which was well matched with the predicted value. The antioxidant activity assay indicated that the phenolic compounds from Phyllanthus urinaria have a good antioxidant activity.

title: Antioxidant and Vasodilatory Action of Grape Juices Produced in Different Regions of Brazil

description: Abstract Background: Grapes and its derivatives (wines and juices) are rich in polyphenols that have high antioxidant and vasodilator capacity. These biological activities may vary in the juices marketed and produced in different regions of Brazil. Objectives: To determine the antioxidant and vasorelaxant effects of grape juice samples produced in different regions of Brazil. Methods: The content of phenolic compounds and antioxidant capacity were evaluated by the methods of Folin-Ciocalteau, DPPH, ABTS and a new electroanalytical approach (differential pulse voltammetry - DPV). Vasodilator effects were analyzed in isolated aorta from rats in an organ bath. Results: The samples from RJ and SP presented respectively the higher and lower phenolic content and also antioxidant capacity by the methods used (ABTS and DPPH). The results of the electrochemical index corroborate to the other tests, with the best results to RJ (21.69 ± 3.15 µA/V) and worse to the SP sample (11.30 ± 0.52 µA/V). In the vascular reactivity studies, the relaxation induced by each sample presented more distinct differences, following the order: RJ (87.9 ± 4.8%) &gt; RS1 (71.6 ± 8.6%) &gt; GO (56.2 ± 7.2%) &gt; SP (39.9 ± 7.8%) &gt; PR (39.4 ± 9.5%) &gt; RS2 (19.5 ± 6.2%). Inhibition of endothelial NO practically abolished (p &lt; 0.001) the relaxation for all samples, except one. Conclusion: The phenolic content and antioxidant capacity vary greatly among samples. The results obtained for the order of antioxidant activity were: RJ &gt; RS1 &gt; GO &gt; RS2 &gt; PR &gt; SP. The juices were able to induce vascular relaxation at quite varied levels, and the RJ sample the most effective. The L-NAME practically blocked all samples except one (RS2).

title: Effect of brine and dry salting methods on the physicochemical and microbial quality of chub (Squalius cephalus Linnaeus, 1758)

description: Abstract The present study, looks at the physicochemical and microbiological quality changes that occur due to different salting techniques (20% salt concentration) of chub (Squalius cephalus) and when stored in 4 ± 0.5 °C. Samples of fish from each group was taken on the 15, 30, 45, 60, 90 and 120th day and was analyzed for nutritional component (crude protein, lipid, moisture, crude ash), pH value, salt content and the microbial flora (total mesophilic aerobic bacteria count, total coliform, total psychrophilic aerobic bacteria count, yeast and mould). It was determined that crude protein, lipid, crude ash and salt amounts in the group where dry salting method was applied were higher than the group where brine salting occurred, in addition protein and lipid values decreased as storage period was longer (P &lt; 0.05). It was determined that there is an increase in total aerobic mesophilic, psycrophile bacteria and enumeration of yeast and mould as storage period increased, while coliform bacteria decreased (P &lt; 0.05).

title: EFFECTS OF WALKING ON THE MOOD OF PHYSICALLY ACTIVE OLDER PEOPLE

description: ABSTRACT Introduction: Due to the relationship between exercise and mood (MO), physical activity is being widely used as a nonpharmacological strategy in the treatment of depression. However, most studies have used sample groups of subjects who, besides suffering from ill health, are also older and sedentary, thus presenting wider “windows of adaptations” when compared to apparently healthy or physically active individuals. Thus, the effects of exercise on MO in physically active elderly individuals are yet to be clarified. Objective: To verify the acute effects of 30 minutes of walking of mild to moderate intensity on the MO of physically active elderly subjects. Methods: A total of 43 volunteers (86% women and 14% men), who participated regularly in an activity program offered by a health care institution in Alagoas, were selected in a non-probabilistic manner. MO was evaluated using the Profile of Mood States (POMS) questionnaire before and after 30 minutes of walking. The comparison between means was verified with Student's t-test. Results: Relative differences were observed in all dimensions of MO, ranging from 16.4% (Vigor) to 56.3% (Rage). However, statistically significant differences were only found in the Vigor (p = 0.00) and Confusion (p = 0.026) dimensions. Conclusion: It is concluded that a 30-minute walk, performed at mild to moderate intensity, as recommended by the main medical guidelines for obtaining general health benefits, may be an effective way of promoting MO improvements in physically active elderly people. The study confirms the fact that walking may potentially be an interesting nonpharmacological strategy for the treatment of depression. Level of Evidence II; Therapeutic studies - Investigating treatment results.

title: Adductor Pollicis Muscle Thickness as a Marker of Nutritional Status in Heart Failure

description: Abstract Background: Malnutrition is associated with morbidity and mortality in patients with heart failure (HF). Thus, it is essential to apply reliable indicators to assess the nutritional status of these individuals. Objective: To evaluate the thickness of the adductor pollicis muscle (APM) in patients with HF as an indicator of somatic protein status and correlate the obtained values with conventionally used parameters and electrical bioimpedance (EBI) markers. Methods: Cross-sectional study with patients with HF undergoing regular outpatient treatment. APM thickness was measured in the dominant arm, and the values obtained were classified according to gender and age. The anthropometric parameters assessed included the body mass index (BMI) and specific parameters to assess the muscle (arm muscle circumference [AMC] and arm muscle area [AMA]). Values of phase angle (PA), standard PA (SPA), and lean mass were obtained by EBI. Statistical analyses were performed with the software Statistical Package for the Social Sciences, version 19, using unpaired Student’s t, Mann-Whitney, or one-way analysis of variance (ANOVA) tests for comparisons between groups, as appropriate. The correlation between variables of interest was performed using Pearson’s or Spearman’s correlation coefficient, as adequate. The level of significance was set at 5%. Results: About 70% of the 74 patients evaluated were classified as malnourished according to the APM thickness. Values of AMC, AMA, and lean mass correlated positively with APM thickness (p &lt; 0.005). The APM thickness also correlated positively with PA and SPA (r = 0.49, p &lt; 0.001 and r = 0.31, p = 0.008, respectively). Conclusion: Patients with HF presented a high frequency of protein malnutrition when APM thickness was used as an indicator of nutritional status. APM thickness values correlated with conventional measures of somatic protein evaluation and may be related to the prognosis of these patients, since they correlated positively with PA and SPA.

title: Telecardiology on the Diagnostic Support of Chest Pain in Twenty-Two Emergency Care Units (UPA 24h) in The State of Rio de Janeiro

description: Abstract Background: Telecardiology may be a useful support in diagnosis and management of chest pain. Objective: Evaluate the application of telecardiology to support the differential diagnosis of chest pain in patients admitted to Emergency Care Units. Method: Observational, retrospective and documental study of 5,816 patients admitted with supposedly cardiological chest pain in twenty two Emergency Care Units in the state of Rio de Janeiro. Data were tabulated and analyzed by Excel® software, using simple descriptive statistics, from the database of the Cardiology Consultancy Nucleus. Results: Diagnostic disagreement was found in 1,593 (27.39%) cases. Of these, 1,477 (92.72%) were diagnosed locally as non-ST-elevation myocardial infarction (non-STEMI), 74 (4.64%) as acute myocardial infarction with ST-segment elevation (STEMI), 40 (2.52%) as acute pulmonary edema (APE) and 2 (0.12%) as tachyarrhythmia. Intensive care referral was requested to 100% of these patients. After telecardiology, the diagnoses were: 385 (24.17%) unstable angina, 289 (18.14%) congestive heart failure, 212 (13.31%) APE, 174 (10.92%) STEMI, 152 (9.54%) hypertensive emergency, 113 (7.09%) acute chronic renal failure, 89 (5.59%) non-STEMI, 89 (5.59%) pneumonia, 39 (2.45%) sepsis, 26 (1.63 %) myopericarditis, 20 (1.26%) tachyarrhythmia and 5 (0.31%) orovalvar disease. The outcome after telecardiology was 1,178 discharges (73.94%), 338 (21.21%) referrals, 62 (3.90%) deaths and 15 (0.95%) unknown. Conclusion: Telecardiology was effective in chest pain diagnosis and management, optimizing hospital admission in the public health system.

title: Arbuscular mycorrhizal fungi and indolebutyric acid alter rooting rate and physiological characteristics of Lantana camara L. (Verbenaceae)?

description: ABSTRACT The objective of this study was to evaluate the rooting and some physiological characteristics of Lantana camara L. (Verbenaceae) stakes in different concentrations of indolebutyric acid (IBA) and its association with the arbuscular mycorrhizal fungi (AMF) Claroideoglomus etunicatum (W.N. Becker & Gerd.) C. Walker & A. Schüssler e Gigaspora albida N.C. Schenck & G.S. Sm. The experimental design was completely randomized in a 3x3 factorial scheme with three replicates, where the first factor was the AMF and the second factor by doses of IBA (0; 1.0 and 1.5 mg .mL-1). The results showed that the presence of AMF in the substrate, as well as the IBA, isolated or in association stimulates the rooting and some physiological characters of L. camara cuttings.

title: Are there differences in birth weight according to sex and associations with maternal exposure to air pollutants? A cohort study

description: ABSTRACT CONTEXT AND OBJECTIVE: Several effects of exposure to air pollutants on human health are known. The aim of this study was to identify whether exposure of pregnant women to air pollutants contributes towards low birth weight and which sex is more affected. DESIGN AND SETTING: Longitudinal study using data on newborns from mothers living in São José do Rio Preto (SP) who were exposed to air pollutants in 2012-2013. METHODS: A hierarchical model on three levels was built using maternal and newborn variables and environmental concentrations of particulate matter, ozone and nitrogen dioxide in quartiles. Preterm new-borns, twins and newborns with birth defects were excluded and exposure windows of 30, 60 and 90 days before delivery were considered. RESULTS: 8,948 newborns were included: 4,491 males (50.2%) and 4,457 females (49.8%); 301 newborns presented low birth weight (3.4%). The mean weight differed between males (3281.0 g) and females (3146.4 g) (P &lt; 0.001). Exposure to ozone was significantly associated with low birth weight in both sexes in the 30-day window (odds ratio, OR = 1.38) and 90-day window (OR = 1.48); and among females, in the 30-day window (OR = 1.58) and 90-day window (OR = 1.59). Exposure to particulate matter had a paradoxical protective effect. No association was found among male newborns. CONCLUSIONS: Female newborns showed greater susceptibility to maternal exposure to air pollutants. Studies on low birth weight in relation to maternal exposure to air pollutants should deal with males and females separately.
