title: Decline of mortality from cervical cancer

description: ABSTRACT Objective: To describe occurrences of mortality due to cervical cancer in Recife (PE), in northeastern Brazil. Method: This was a time-series ecological study using data from the Mortality Information System (SIM) regarding the total number of deaths due to cervical cancer (C53 ICD10) that occurred between 2000 and 2012. Results: It was observed that the risk of death due to this form of cancer was higher among women over 60 years of age, those of mixed skin color (53.24%), those who only worked at home (63.16%) and those who did not have a partner (44.32%). Conclusion: Additional efforts towards maintaining early detection and health education programs and towards using therapeutic strategies of greater efficiency are needed, given that mortality due to this form of cancer is considered avoidable when diagnosed early.

title: Intraconal plasmocytoma and uveal infiltration in a patient with multiple myeloma

description: Abstract Multiple myeloma (MM) leads to disorderly proliferation of plasma cells clones, producing monoclonal immunoglobulin and commonly presents osteolytic lesions. In some cases, however, masses called plasmocytomas are found. Ocular and orbital involvement is unusual in this pathology. In this paper, we describe a case of a 63 year-old patient with previous diagnostic of MM that evolved an intraconal plasmocytoma in the right eye, as well as a vascularized mass in the anterior chamber from uveal infiltration. These lesions were correlated to MM e lead to visual loss in the affected eye. Reports of intraconal plasmocytoma have not been found in literature.

title: Microstructure and thermal and functional properties of biodegradable films produced using zein

description: Abstract Research is being conducted in an attempt to produce biodegradable packaging to replace plastic products, thereby reducing solid waste disposal. In this work, zein films were produced from vegetable oils (macadamia, olive and buriti) and from pure oleic acid. The surface of zein-based films made using oleic acid has a good lipid distribution. The high content of oleic acid produced a film with the greatest elongation at break (8.08 ± 2.71%) due to the greater homogeneity of the protein matrix. The different oils did not affect the glass transition temperature (Tg). Tg curves of films with fatty acids showed a reduction in mass at between 50 and 120 °C due to water evaporation. At 120 °C the weight loss was 3-5% and above this temperature further weight loss was observed with the highest loss being seen in the film made using pure oleic acid. In conclusion, although biodegradable films were produced using the four different oils, the film made from pure oleic acid has the best characteristics.

title: Effect of PVA and PDE on selected structural characteristics of extrusion-cooked starch foams

description: Abstract The aim of this work was to determine selected physical properties of biodegradable thermoplastic starch (TPS) filling foams manufactured by extrusion-cooking technique from different combinations of potato starch and two additives: poly(vinyl alcohol) PVA and Plastronfoam PDE. Foams were processed with seven starch/additives combinations at two different extruder-cooker’s screw rotational speeds. The densities of starch foams depended significantly on the additive type and content. The linear relationship between the Young modulus and the ultimate compression force and apparent density was found. The foams processed with the addition of PVA had low density, porosity and lower values of the Young modulus than the foams prepared with PDE.

title: Magnetic Solid-Phase Extraction Combined with Dispersive Liquid-Liquid Microextraction Followed by HPLC for Determination of Four Aromatic Amines Released from Azo Dyes in Paper Samples

description: A novel extraction technique combining dispersive liquid-liquid microextraction (DLLME) with magnetic solid-phase extraction (MSPE) is presented for pre-concentration of four primary aromatic amines (PAAs) released from azo dyes in paper samples prior to high performance liquid chromatography (HPLC). n-Octanol was used as the extractant and hydrophobic oleic acid modified Fe3O4 nanoparticles (Fe3O4@OA NPs) as an efficient adsorbent was applied to retrieve the PAAs-containing n-octanol in the DLLME step. Because of the rapid mass transfer associated with the DLLME and MSPE steps, fast extraction could be achieved. The main parameters affecting the efficiency of MSPE-DLLME procedure of PAAs were investigated and optimized. Under optimum conditions, the recoveries ranged from 79.6 to 88.5% and the limits of detection (LODs) were in the range of 0.21-1.16 ng mL-1 (S / N = 3). The intra-day precision (relative standard deviation (RSD)) was below 7.8% and inter-day RSD was less than 11%.

title: A DEFENCE OF EDUCATIONAL PERSPECTIVE OF TEACHERS’ PROFESSIONAL DEVELOPMENT IN EDUCATIONAL PRACTICE OF CHEMISTRY TEACHERS

description: Teachers’ Professional Development (TPD) has been defined as learning opportunities, insights and discussions that improves the personal, social and pedagogical growing of the teachers, whose main goal is the enhancement of their knowledge about teaching strategies and research skills around educational practice. The above topics are needed to change the learning and teaching forms in chemical education; however, the tie between TPD and the classroom practice of the chemistry teachers still has not been greatly discussed in the literature. Thus, this paper seeks to generate a perspective upon theoretical issues related with TPD and their relevance in the chemistry teaching, where the teacher as researcher is put forward as a promoter of classroom research projects, which he joins chemical, pedagogical and practical knowledge for the improvement of learning process of his students. Moreover, the fruitful relationship between TPD and teaching of chemistry educators with the aim to make teachers’ communities around their professional development is analyzed.

title: OPTIMIZATION OF SOLID-LIQUID EXTRACTION WITH LOW TEMPERATURE PARTITION FOR DETERMINATION OF CARBOFURAN IN CUCURBITA PEPO L (“ZUCCHINI”) BY HIGH PERFORMANCE LIQUID CHROMATOGRAPHY

description: According to results of the Program of Analysis of Pesticide Residues in Foods of the National Agency of Sanitary in Brazil (2013 to 2015) the zucchini, Cucurbita pepo L is one of the non-hardy vegetables, that presented higher contamination index by pesticides residues. One of these agrochemicals is carbofuran, which although not authorized for this crop, is commonly and illegally used for whitefly control. The objective of this study was to optimize the solid-liquid extraction method with low temperature partitioning (SLE/LTP) for the determination of carbofuran residues in zucchini by high performance liquid chromatography with ultraviolet detector (HPLC-UV). The optimization was performed with a complete factorial design, 2³ to evaluate the simultaneous performance of three factors in two levels, in triplicate. The optimized SLE/LTP-HPLC/UV method showed to be selective, simple and efficient, consuming a small amount of sample and solvent extractor. The average recovery percentage was 75.88%. Samples of zucchini purchased in the Itumbiara-GO trade, Brazil, and submitted to the optimized method did not present carbofuran residues.

title: Correlation between Very Short and Short-Term Blood Pressure Variability in Diabetic-Hypertensive and Healthy Subjects

description: Abstract Background: Blood pressure (BP) variability can be evaluated by 24-hour ambulatory BP monitoring (24h-ABPM), but its concordance with results from finger BP measurement (FBPM) has not been established yet. Objective: The aim of this study was to compare parameters of short-term (24h-ABPM) with very short-term BP variability (FBPM) in healthy (C) and diabetic-hypertensive (DH) subjects. Methods: Cross-sectional study with 51 DH subjects and 12 C subjects who underwent 24h-ABPM [extracting time-rate, standard deviation (SD), coefficient of variation (CV)] and short-term beat-to-beat recording at rest and after standing-up maneuvers [FBPM, extracting BP and heart rate (HR) variability parameters in the frequency domain, autoregressive spectral analysis]. Spearman correlation coefficient was used to correlate BP and HR variability parameters obtained from both FBPM and 24h-ABPM (divided into daytime, nighttime, and total). Statistical significance was set at p &lt; 0.05. Results: There was a circadian variation of BP levels in C and DH groups; systolic BP and time-rate were higher in DH subjects in all periods evaluated. In C subjects, high positive correlations were shown between time-rate index (24h-ABPM) and LF component of short-term variability (FBPM, total, R = 0.591, p = 0.043); standard deviation (24h-ABPM) with LF component BPV (FBPM, total, R = 0.608, p = 0.036), coefficient of variation (24h-ABPM) with total BPV (FBPM, daytime, -0.585, p = 0.046) and alpha index (FBPM, daytime, -0.592, p = 0.043), time rate (24h-ABPM) and delta LF/HF (FBPM, total, R = 0.636, p = 0.026; daytime R = 0,857, p &lt; 0.001). Records obtained from DH showed weak positive correlations. Conclusions: Indices obtained from 24h-ABPM (total, daytime) reflect BP and HR variability evaluated by FBPM in healthy individuals. This does not apply for DH subjects.
