title: Evaluation of Quality of life, Physical Activity and Nutritional Profile of Postmenopausal Women with and without Vitamin D Deficiency

description: Abstract Introduction Vitamin D deficiency is associated with various diseases. Prevalent in Brazil, it can result from inadequate lifestyle habits. Objective To demonstrate that postmenopausal women with vitamin D deficiency have worse quality of health, expressed as worse quality of life, lower levels of physical activity, and worse nutritional profile. Methods Postmenopausal women answered questionnaires about physical activity and quality of life, provided a 24-hour food record, and had serum vitamin D levels measured. Results Among the more active women, those who perform a daily average of one hour of physical activity had vitamin D levels above 20 ng/mL (76.9%), and those, which expose themselves to sunlight, had vitamin D levels above 30 ng/mL (34.6%). Meanwhile the percentages for the women who are less physically active and less exposed to sunlight were 42.2% and 8.9% respectively. Being more active and more exposed to sunlight resulted in a lower fat percentage. Serum vitamin D levels were not correlated with quality of life. Conclusion Walking and gardening increased serum vitamin D levels and decreased the percentage of body fat. The limitations of the study prevented the impact of 25hidroxyvitamin D on the quality of life and nutritional aspects of the women from being evaluated.

title: LANDSCAPE THEORY APPLIED TO THE CHOICE OF AREAS FOR LANDFILLS

description: ABSTRACT This paper aims to create a proposal for methodological adaptation of planning, which subsides to a new model of analysis and choice of locations with geoecological potential for installing landfills in the city of Anhumas in the Western Plateau of São Paulo State. Hence, we used Landscape Theory, based on the systemic approach. The importance of this proposal lies in the fact that Anhumas is part of one of the areas most impacted by effluent percolation on porous soils in São Paulo State, showing high levels of environmental fragility in the face of porous soils from the sandstone rocks that make up this region. However, there are no studies that incorporate natural systems to anthropic systems in planning the choice of areas for solid waste landfills. For this purpose, we adopted the methodology for the study and planning of the landscape highlighting the functional diagnostics, weaknesses and intrinsic potential.

title: Development of a low cost experimental apparatus for the falling objects study: analysis of the magnets movement in vertically oriented pipes

description: The movement exhibited by falling magnets inside pipes is a phenomenon of great potential to explore important physical laws such as the falling bodies of Galileo and Faraday-Lenz ones. While the magnet describes an accelerate movement in non-metallic pipes, in non-ferromagnetic metallic pipes it quickly becomes uniform due to a resistive force acting. In this work we propose a low cost experimental apparatus to thoroughly study both behaviors. An ultrasonic sensor is coupled to the Arduino microcontroller to monitor the magnet displacement in short time intervals and, thereafter, the speed and acceleration are determined. To verify the proposed apparatus, we investigate the magnet motion in metal and non-metallic pipes and we obtained consistent results with the underlying theory, which suggests an efficacy of the apparatus. In addition, when we compare two different theoretical approaches, we verify it is necessary to introduce a multiplicative factor in one of them so that the results become coherent.

title: Definitive Contraception: Trends in a Ten-year Interval

description: Abstract Objective To evaluate the trends in definitive contraception in a ten-year interval comprising the years 2002 and 2012. Method Retrospective analysis of the tubal sterilization performed in our service in 2002 and2012,analyzingthedemographiccharacteristics,personalhistory,previouscontraceptive method, definite contraception technique, effectiveness and complications. Results Definitive contraception was performed in 112 women in 2002 (group 1) and in 60 women in 2012 (group 2). The groups were homogeneous regarding age, parity, educational level and personal history. The number of women older than 40 years choosing a definitive method was more frequent in group 1, 49.1% (n = 55); for group 2, the rate was 34.8% (n = 23) (p = 0.04). The time between the last delivery and the procedure was 11.6±6.2 and 7.9±6.4 years (p = 0.014) in 2002 against 2012 respectively. In 2002, all patients performed tubal ligation by laparoscopic inpatient regime. In 2012, the bilateral placement of the Essure (Bayer Corporation, Whippany, NJ, US) device was suggested to 56.1% (n = 37) of the patients, while laparoscopy was suggested to 43.9% (n = 29) of them. All women who underwent laparoscopic sterilization had the procedure successfully completed using silastic rings. The overall bilateral device placement rate for the Essure was 91.6%, with only one complication reported. All Essure procedures were performed in an outpatient setting; for the laparoscopy, this rate was 79% (n = 15). No intentional pregnancies occurred until this date. Conclusions There is a trend in the decrease in definitive contraception over the years in our institution, maybe as a result of the development of long-acting reversible contraceptives. The hysteroscopic procedure has become a frequent option, as it is performed in an office setting without anesthesia, being a well-tolerated, minimal invasive method.

title: Evaluation on the Scientific Production in Fields of Medicine: a Comparative Study

description: ABSTRACT Objective Knowledge production, technology generation and human resource training for research are themes which have been under the limelight in the academic and governmental environment. The aim of this study was to compare the scientific productivity, human resource training and the profile of researchers awarded scientific productivity grants by the CNPq (Brazilian Council for Scientific and Technological Development), from medical knowledge areas. Methods This is a descriptive and comparative study among researchers with scholarships in the fields of Cardiology, Hematology/Oncology, Nephrology/Urology, Pediatrics and Clinical Neuroscience, obtained through previous studies. The variables analyzed were: gender, researcher home institution, PhD time, doctoral institution, undergraduate research guidelines, master’s and doctorate degrees, and publications in journals. The researchers granted with the PQ (scientific productivity) grants were also divided into the present CNPq categories of: 2, 1A, 1B, 1C and 1D. Results from a total of 411 researchers in Medicine, 192 (46.7%) were identified as belonging to areas of the five studies involved, predominantly male (71.3%), concentrated in categories 2 and 1A. The southeastern and southern Brazilian regions together comprise the majority of the researchers (over 90.0%) and São Paulo accounted for 63.0% of the researchers, also hosting the two main institutions – Universidade Federal de São Paulo (Unifesp) and Universidade de São Paulo (USP) – containing 49.5% of the stock. There was a prevalence students undergoing of teacher training (1,846 master’s degree supervisions), followed by 1,674 undergraduate and 1,115 doctoral students. Of the 18,456 articles that were published in journals, 56.0% of them indexed in the ISI database and 78% in Scopus. Conclusions In this study, it was noted that all the analysed fields showed growing scientific productivity, above all Clinical Neuroscience, and expressive human resource training, with a constant for improving quality performance. However, regional disparity was found as regards the concentration of researchers, as well as a lack of patent production.

title: USE OF RESIDUES OF FORESTRY EXPLORATION OF Pinus taeda FOR PARTICLEBOARD MANUFACTURE

description: ABSTRACT This study aimed to evaluate the quality of particleboards manufactured with forest exploitation waste from Pinus taeda. The material in the form of branches, tree tops, stumps and roots, was obtained from a forest plantation located in the Municipality of Mafra -SC. All the material was processed into wood chips for biomass and transported to the place of studies. The Pinus industrial particles were used as control and mixed with the waste in different proportions. The experimental plan consisted of the panels manufacture with 100% of each type of material and mixture of these com proportions of 75/25%, 50/50% and 25/75% with Pinus industrial particles, in addition to the mixture in equal parts, of the three types of materials. Experimental panels were manufactured with nominal density of 0.75 g/cm3, using the urea-formaldehyde resin, in the proportion of 8% of solids -dry weight basis of the particles. The panels were pressed with specific pressure of 4.0 MPa, temperature of 160ºC and pressing time of 8 minutes. The results of the internal bond tests met the requirements of the standard EN 312, is indicative that there has been a proper bonding of these particles originating forest exploitation wastes. General evaluations of the physical and mechanical properties results of the experimental panels indicate the possibility of use of particles obtained from branches, tree tops, stumps and roots, mixed com the industrial Pinus particles, in proportion of, up to, 50%, for particleboard manufacture.

title: NEUROBLASTOMA CELL-LINE TOXICITY DUE TO INCREASED ALZHEIMER'S-RELATED PROTEINS AND CELL DEATH SUBSEQUENT TO HIGH-DOSE PALMITIC ACID EXPOSURE

description: Obesity caused by high-fat diet (HFD) consumption is one of the risk factors for the development of Alzheimer's disease (AD). Previous studies have reported that saturated fatty acids from an HFD, particularly palmitic acid (PA), promotes Alzheimer's pathologies, neuroinflammation and cognitive impairment. The pathological hallmarks of AD are characterized by the accumulation of amyloid-? (A?) peptides and phosphorylated Tau (pTau) proteins. However, the expression of A? peptides, and Tau proteins levels, as well as the viability of cell in neuronal cells induced by PA remain unclear. Therefore, this study aims to determine the effect of high concentrations of PA on cell viability and Alzheimer's-related proteins of neuronal cells. In this study, SH-SY5Y was used as a neuronal cell model in order to investigate the effect of PA at a concentration of 400 and 800 ?M. The results showed that neuronal cell exposed to PA at doses of 400 and 800 ?M for 24 and 48 hours had decreased cell viability in a dose-dependent manner. In addition, receiving PA for 48 hours induced A? peptides and p-Tau proteins production. Our study suggests that high concentration of PA exposure can lead to increased risk of the development of Alzheimer's pathologies and neuronal cell death.

title: FLORISTIC-STRUCTURAL VARIATION OF NATURAL REGENERATION ALONG DIFFERENT TOPOGRAPHIC POSITIONS OF AN ECOTONAL FOREST IN SANTA CATARINA, BRAZIL

description: ABSTRACT Studies on the natural regeneration of tree species communities are important for providing information on forest development capacity. This research aimed to evaluate the floristic-structural variations of the tree regenerative component along a topographic gradient in an ecotonal area between a Mixed Ombrophilous Forest and a Deciduous Seasonal Forest of Santa Catarina, Brazil. 30 sampling units of which all regenerating tree species individuals have been identified were allocated in the forest fragment. The sampling units were then distributed along a topographic gradient into lower, intermediate and upper sectors. Abundance, richness, Shannon's diversity index (H') and Pielou's evenness index (J) have been determined for both the whole community as for each sector. The community floristic-structural organization was verified by the means of the non-metric multidimensional scaling (NMDS), the indicator species analysis and the permutational multivariate analysis of variance (PERMANOVA). Abundance differences among sectors were analyzed through the Kruskal-Wallis test with post hoc multiple nonparametric test while richness differences were verified through rarefaction. Regenerating individuals density in the upper sector [129 (21.300 ind.ha-1)] was lower than both in the lower [401 (63.800 ind.ha-1)] and intermediary [241 (36.300 ind.ha-1)] sectors. There was variation in the floristic-structural composition (p &lt; 0.001) among topographic positions; the lower sector was the most distinct one and showed the highest number of indicator species.
