title: Phytotherapy in pediatrics: the production of knowledge and practices in Primary Care

description: ABSTRACT Objective: To demonstrate the use of phytotherapy as a therapy adopted in the context of Primary Care to Childhood. Method: Observational and analytical field research, with quantitative-qualitative approach. A semi-structured survey was used on socio-demographic and ethnopharmacological variables, audio interview and daily observation. Results: The production of knowledge about phytotherapy constitutes a family heritage, but incorporated data resulting from the daily experiences shared by the community. The main factors were: easy access to this resource, high costs of conventional treatment, difficulty in accessing medical services and belief in the power of plants. The attributed meanings were: prevention and treatment of injuries, rescue of memory and of experiences, factor integrative with nature and aggregative among members of the community. Final considerations: Rescuing this tradition brings a new meaning to health care.

title: Epidemiological profile of maternal mortality

description: ABSTRACT Objective: To know the epidemiological profile of maternal mortality in Juiz de Fora, a city in the state of Minas Gerais. Data collection was carried out from April to December 2016. Method: Summary of a confidential investigation of maternal mortality on deaths occurred from January 1st, 2005 to December 31, 2015. Results: Eighty-five deaths of women residing in Juiz de Fora were identified and analyzed. The age group was between 20 and 36 years. The women carried out prenatal care (74.1%) with less than six visits (34.0%). Cesarean section was conducted in 38.8% of the childbirths and the obstetric treatment was considered appropriate (32.9%). The first cause of maternal death was hypovolemic shock 12 (14.10%), followed by uterine hypotony 6 (7.0%). Conclusion: Cesarean section rates are high and prenatal adherence is lower than that expected, which could justify the number of deaths in the period studied.

title: ADSORPTION OF BIODIESEL CONTAMINANTS BY SURFACE-MODIFIED BAGASSE FIBERS

description: Sugarcane bagasse fibers chemically modified on its surface were used to adsorb contaminants from biodiesel. Two biodiesel samples were used as adsorbates: crude and washed biodiesel. The contaminants were mainly glycerol and water, but also ions, and methanol. The biodiesel is usually washed, in order to remove most of the contaminants, but the procedure introduces large amounts of water, which are further difficult to remove, because the biodiesel acting as an acceptor of hydrogen bond. The adsorbent used in this work was proved to be very efficient to remove the contaminants and also to remove water from the washing the crude biodiesel. The contaminants adsorbed from biodiesel were identified by thermal analyses (DSC and DTA) of the fibers (adsorbent) and of the biodiesel (adsorbate) by comparing the results with the pure biodiesel. The proportion of free glycerol showed high adsorption efficiency for the crude biodiesel. A total amount of 1.34 g of fibers was estimated as being needed for its complete removal. The mass of bagasse fibers added (up to 1g) in a fixed volume of biodiesel was a relevant condition, as the saturation in fibers started at around 0.70 g cleaning up to about 98% removal of the impurities.

title: OPTOELECTRONIC PROPERTIES OF TRIPHENYLAMINE BASED DYES FOR SOLAR CELL APPLICATIONS. A DFT STUDY

description: Abstract: Dye-sensitized solar cells (DSSCs) based on triphenylamine (TPA) as a donor group linked with the acceptor cyanoacrylic acid electron acceptor by 2,2’-bithiophene as π-bridged (D-π-A) has been investigated by Density Functional Theory (DFT) at the B3LYP/6-311G(d,p) level of theory, to establish the conformational orientation of cyanoacrylic acid group as well as evaluate the effect of planarizing the 2,2’-bithiophene unit in position 3 and 3’ by electron withdrawing or donor groups on the electronic structure properties of ground and doping(n,p) states. Also, the Time Dependent Density Functional Theory (TD-DFT) at the CPCM-TD-CAM-B3LYP//CAM-B3LYP/6-311G(d,p) level of theory were selected to modulate the electronic absorption spectra and charge-transfer capabilities of the molecules analyzed in the present work. The results indicate that adding an auxiliary donor or withdrawing group to the 2,2’-bithiophene in the (D-π-A) arrangement allow to modify the LUMO’s energy of the dyes, while the HOMO's energy is slightly affected.

title: People living on the street from the health point of view

description: ABSTRACT Objective: To know the Brazilian scientific production of the last ten years (2007 to 2016) about people who experience street situations under the health gaze. Method: Integrative literature review using the descriptors: street people, health policy and public health. We analyzed 21 articles available in the Virtual Health Library. Results: Four categories of analysis emerged. There was an increase in the frequency of published work on the subject, showing that the experience of living on the street makes people vulnerable to various diseases and health problems and, in addition, increases the difficulties of access to health services. Conclusion: There was an increase in the discussion of this topic due to the increase in the number of published studies. Despite the existence of public health policies directed to this social group, much still needs to be done to guarantee the health of this population.

title: Autonomic and Vascular Control in Prehypertensive Subjects with a Family History of Arterial Hypertension

description: Abstract Background: Individuals with a family history of systemic arterial hypertension (FHSAH) and / or prehypertension have a higher risk of developing this pathology. Objective: To evaluate the autonomic and vascular functions of prehypertensive patients with FHSAH. Methods: Twenty-five young volunteers with FHSAH, 14 normotensive and 11 prehypertensive subjects were submitted to vascular function evaluation by forearm vascular conductance(VC) during resting and reactive hyperemia (Hokanson®) and cardiac and peripheral autonomic modulation, quantified, respectively, by spectral analysis of heart rate (ECG) and systolic blood pressure (SBP) (FinometerPRO®). The transfer function analysis was used to measure the gain and response time of baroreflex. The statistical significance adopted was p ≤ 0.05. Results: Pre-hypertensive individuals, in relation to normotensive individuals, have higher VC both at rest (3.48 ± 1.26 vs. 2.67 ± 0.72 units, p = 0.05) and peak reactive hyperemia (25, 02 ± 8.18 vs. 18.66 ± 6.07 units, p = 0.04). The indices of cardiac autonomic modulation were similar between the groups. However, in the peripheral autonomic modulation, greater variability was observed in prehypertensive patients compared to normotensive individuals (9.4 [4.9-12.7] vs. 18.3 [14.8-26.7] mmHg2; p &lt; 0.01) and higher spectral components of very low (6.9 [2.0-11.1] vs. 13.5 [10.7-22.4] mmHg2, p = 0.01) and low frequencies (1.7 [1.0-3.0] vs. 3.0 [2.0-4.0] mmHg2, p = 0.04) of SBP. Additionally, we observed a lower gain of baroreflex control in prehypertensive patients compared to normotensive patients (12.16 ± 4.18 vs. 18.23 ± 7.11 ms/mmHg, p = 0.03), but similar delay time (-1.55 ± 0.66 vs. -1.58 ± 0.72 s, p = 0.90). Conclusion: Prehypertensive patients with FHSAH have autonomic dysfunction and increased vascular conductance when compared to normotensive patients with the same risk factor.

title: Effects of taurine supplementation in elite swimmers performance

description: Abstract AIM Taurine is considered a semi-essential amino acid characterized by having various physiological functions in the body that modulate mechanisms of action involved in the muscle contraction process, increased energy expenditure, insulin signaling pathway, carbohydrate metabolism, and scavenging free radicals. These functions are crucial for aerobic exercise performance; thus, taurine supplementation may benefit athletes’ performance. The objective of this study was to evaluate the effects of taurine supplementation on the resting energy expenditure and physical performance of swimming athletes. METHODS In a double-blind study, 14 male swimmers were randomized into two groups: the taurine group (n = 7) and the placebo group (n = 7), which received 3 g per day of taurine or placebo in capsules during 8 weeks. Resting energy expenditure, plasma taurine, physical performance, anthropometry, dietary consumption were measured and an incremental test was performed to determine their maximal front crawl swimming performances before and after the 8-week period. RESULTS The levels of serum taurine (p &lt; 0.0001) and lactate (p = 0.0130) showed a significant increase in the taurine group; however, the other variables were not different. No changes were observed in the resting energy expenditure, mean speed performed, and the anaerobic threshold of the swimmers post-supplementation period. CONCLUSION Supplementation of taurine increased plasma concentrations of this amino acid, but did not lead to significant changes in food intake, rest energy expenditure, and athletes’ performance. However, the supplemented group presented a higher lactate production, suggesting a possible positive effect of taurine on the anaerobic lactic metabolism.

title: The “y”, the Article and Orthography: Censorship and the Portuguese Vernacular in 18th Century

description: Abstract This article explores a secret debate between several Portuguese censors, in 1771, on two spelling books: the Resumo da grammatica da lingua portuguesa by Antonio José dos Reis Lobato, and the Breve tratado da orthografia, para os que não frequentam os estudos, ou dialogos sobre as mais principaes regras da orthografia, uteis para o povo menos instruido, accrescentado com hum dialogo da prozodia portugueza, by João Pinheiro Freire da Cunha. In eight written opinions on these two books, submitted to the Real Mesa Censória for analysis as to their publication, the censors advanced debates on orthodoxy and pluralism, freedom of expression and scientific advance, while seeking to establish parameters of an official vernacular of the Portuguese language, expanding beyond the prohibition of books, the idea of censorship that is traditionally seen by historiography.

title: Microemulsion as Sample Preparation for Direct Flame Atomic Absorption Spectrometry (FAAS) Determination of Total Iron in Crude and Refined Vegetable Oils

description: This work proposed a novel, relatively low-cost and rapid analytical method using microemulsion as sample preparation to determine iron (Fe) in vegetable oils by flame atomic absorption spectrometry technique (FAAS). The vegetable oil microemulsions were obtained by mixing appropriate proportions of the crude and refined vegetable oil, Triton® X-100, 1-propanol and nitric acid 50% (v v-1). Moreover, an external calibration method was established using aqueous Fe standards instead of expensive and unstable organometallic standards. The limits of detection and quantification were 0.40 and 1.3 mg kg-1 of oil, respectively. The accuracy was checked by recovery studies (with recoveries ranging 84-105%) and by Fe determination in digested vegetable oil samples by inductively coupled plasma optical emission spectrometry (ICP OES) as comparative procedure. The proposed analytical method was efficient to determine Fe in crude and refined vegetable oils from various vegetable sources, besides being suitable for routine analyses due to its simplicity.

title: Substrate and temperature on germination and performance of Albizia niopoides Benth. Seedlings

description: ABSTRACT: This study aimed to determine the most appropriate conditions of temperature and substrate for germination and performance of A. niopoides seedlings. The design was completely randomized in 10x7 factorial arrangement (eight constant temperatures of 5, 10, 15, 20, 25, 30, 35, and 40°C and two alternating temperatures of 20-30 and 25-35°C, and seven substrates, that are paper towel, vermiculite, sand, blotting paper, coir dust, sugarcane bagasse, and tropstrato®) with four replicates of 25 seeds. The following variables were analyzed: (1) germination percentage; (2) germination speed index; (3) shoot length and primary root; and (4) dry weight of shoot and of root system. There was a significant interaction among the tested factors for all variables. The A. niopoides seeds germinate under a wide temperature range, with minimum and maximum limit at 10 and 40°C temperatures, respectively. Alternating temperatures of 20-30 and 25-35°C with sand substrate are ideal conditions for germination and performance of A. niopoides seedlings.
