title: Effect of linear and undulating training periodization models on the repeated sprint ability and strength of soccer players

description: Abstract Purpose: The aim of the study was to investigate the effect of linear and undulating strength-power training scheme on the repeated sprint ability (RSA) and lower body strength of soccer players. Method: Twenty soccer players (under-20 category) were split into 2 groups: the linear load (LL, n=10) and the undulating load (UL, n=10). In the commencement and at the end of the 6-week pre-season period, the RSA test (6 x 35m) and the 1RM parallel squat test (1RMsquat) were conducted. The LL and UL performed the same type and number of sessions. The training stimulus in the strength training was different between LL (Weeks 1 and 2 = Muscular Endurance; Weeks 3 and 4 = Strength; Weeks 5 and 6 = Power) and UL (daily load variation in the same week). Results: A improvement in RSAmean and 1RMsquat was detected in LL and in UL. No significant difference was noted between LL vs UL for all variables. Conclusion: Both groups improved maximal muscle strength in parallel back squat and RSA. UL induced a greater gain in RSA.

title: Factors associated with leprosy in a municipality of the Pre-Amazon region, state of Maranhão, Brazil

description: Abstract INTRODUCTION: The Integrated Program of Leprosy Control was initiated in the municipality of Buriticupu, Maranhão, Brazil, an area considered hyperendemic for leprosy in 2003. It aims at assessing the clinical and epidemiological characteristics of the disease to reduce the detection rate of new cases until 2015. Here, we present the evolution of the indicators of leprosy within the period from 2003 to 2015. METHODS: We conducted a descriptive analytical study based on the active search for and voluntary referral of cases of leprosy. The detection rate of new cases was analyzed over time. We included individuals diagnosed with leprosy between January 2003 and December 2015. The association between categorical variables was assessed using the chi-square test of independence, considering a level of significance of 5%. When the association was significant, the detection rate (with a confidence interval of 95%) was calculated. RESULTS: Overall, 879 new leprosy cases were detected; the majority of the affected individuals were men (65.9%). Multibacillary leprosy was the most common type of the disease, according to the operational classification (55.5%); it showed the strongest association with an age ≥60 years. We also detected an association between the male sex and both, lepromatous and multibacillary leprosy. The detection rate reduced from 211.09/100,000 population in 2003 to 50.26/100,000 population in 2015. CONCLUSIONS: We found an improvement in leprosy control, with a reduction in the detection rate and the absolute number of cases. Strengthening of disease control measures should be prioritized to eliminate leprosy as a public health concern in this municipality.

title: Citral effect in male NMRI mice nonalcoholic steatosis model: assessing biochemical and histological parameters and PPARα gene expression

description: Citral is a small molecule present in various citrus species, with reported anti-hyperlipidemic and anti-inflammation effects. Here, the effect of intraperitoneal (IP) administration of citral is evaluated in a mouse model of non-alcoholic steatosis. Male NMRI mice were divided into the following groups (n = 12): normal control group (NC) receiving a normal diet; high-fat emulsion group (HF) receiving high fat diet for four weeks; positive control group (C+) receiving HF diet for four weeks and then shifted to normal diet with IP-administered silymarin (80 mg/kg) for four weeks; sham group receiving HF diet for four weeks and then shifted to normal diet for four weeks; and EC1, EC2, and EC3 groups receiving HF diet for four weeks and then shifted to normal diet with IP-administered citral doses of 5, 10, and 20 mg/kg, respectively. HF diet resulted in steatohepatitis with impaired lipid profile, high glucose levels and insulin resistance, impaired liver enzymes, antioxidants, adiponectin and leptin levels, decreased PPARα level, and fibrosis in the liver tissue. Upon treatment with citral, improvement in condition was observed in a dose-dependent manner-both at histological level and in the serum of treated animals. and the PPARα level was also increased.

title: Information theory applications in neuroscience

description: Abstract Neurons respond to external stimuli by emitting sequences of action potentials (spike trains). In this way, one can say that the spike train is the neuronal response to an input stimulus. Action potentials are “all-or-none” phenomena, which means that a spike train can be represented by a sequence of zeros and ones. In the context of information theory, one can then ask: how much information about a given stimulus the spike train conveys? Or rather, what aspects of the stimulus are encoded by the neuronal response? In this article, an introduction to information theory is presented which consists of historical aspects, fundamental concepts of the theory, and applications to neuroscience. The connection to neuroscience is made with the use of demonstrations and discussions of different methods of the theory of information. Examples are given through computer simulations of two neuron models, the Poisson neuron and the integrate-and-fire neuron, and a cellular automata network model. In the latter case, it is shown how one can use information theory measures to retrieve the connectivity matrix of a network. All codes used in the simulations were made publicly available at the GitHub platform and are accessible trough the url: github.com/ViniciusLima94/ticodigoneural.

title: MICROWAVE-ASSISTED SYNTHESIS AND PKA DETERMINATION OF UMBELLIFERONE: AN EXPERIMENT FOR THE UNDERGRADUATE ORGANIC CHEMISTRY LABORATORY

description: A synthetic procedure for obtaining the fluorescent coumarin umbelliferone (7-hydroxycoumarin) and its spectral parameters were fully developed aiming at an undergraduate organic chemistry laboratory class. Umbelliferone is traditionally prepared via Pechmann condensation using malic acid, resorcinol and sulfuric acid as catalyst. The use of domestic microwave oven and the absence of solvent allow our methodology to be simple, fast and easy applied in obtaining umbelliferone at organic chemistry laboratory being greener than classical techniques of synthesis. In this class the student will learn how to measure the potency of a microwave oven, the applicability of this kind of irradiation in the organic synthesis of fluorescent compounds and how to determine the pKa of an organic compound through an UV/VIS spectrometric analysis. These experiments were designed to be suitable for a second and third year undergraduate curriculum.

title: EVALUATION OF MOBILE DEVICE INDOOR MAPS FOR ORIENTATION TASKS

description: Abstract This research investigates subjective user preference for using Floor Plans and Schematic Maps in an indoor environment, and how users locate and orient themselves when using these representations. We sought to verify the efficiency of these two kinds of digital maps and evaluate which elements found in physical environments and which elements found in the representations influence the user spatial orientation process. Users answered questions and performed orientation tasks which indicated their level of familiarity with the area being studied, their understanding of the symbology used, and their identification of Points of Interest (POI) in the environment. The initial results indicated a preference for the Schematic Map, because users thought that the symbology used on the map adopted was easy to understand.

title: Princípios para o currículo de um curso de Química

description: ABSTRACT This article describes the most recent Chemistry undergraduate curriculum of USP’s Institute of Chemistry. We point out how the institutional option for professional training to meet the demands of scientific research, the productive sector and basic education, allied to the characteristics of a research institute and previous curricular experiences, led to some principles that served to structure and organize the curriculum. Among these principles, the following stand out: academic freedom for students to choose their profession and define their formative route; a solid base of chemical knowledge and encouragement for constant studies. Finally, it points out that a curricular change should not be limited to changes in the courses offered. The next step involves a real culture change that focuses on a more active learning process.

title: BIOFUELS FROM COCONUT FAT AND SOYBEAN OIL: MICROWAVE-ASSISTED SYNTHESIS AND GAS CHROMATOGRAPHY/MASS SPECTROMETRY ANALYSIS

description: We developed a project during an undergraduate course (advanced experimental chemistry) on the microwave-assisted synthesis of biodiesel (BD), via base-catalyzed transesterification of coconut fat (CF) and soybean oil (SO) by ethanol, followed by product analysis by gas chromatography/mass spectrometry. Our goals were to introduce a problem with relevant socio-economic impact (production of BD); to discuss and compare methods for biofuel analysis, and to gain insight into transesterification mechanism as an important example of acyl-transfer reactions. Comparison of both BFs showed clear difference in fatty acid composition; that from CF contains shorter, saturated chains (mainly ethyl dodecanoate- and tetradecanoate), whereas biodiesel from SO is essentially composed of longer unsaturated chains (e.g., ethyl oleate and linoleate). The project takes eight hours to complete, is conceptually simple, being suitable for inclusion in the undergraduate science curriculum.

title: Violence against women: historical trajectory of a care program (Curitiba - 1997-2014)

description: ABSTRACT Objective: To analyze the historical trajectory and the contributions of the Programa de Atenção às Mulheres em Situação de Violência (Program of Care to Women Victims of Violence) of Curitiba. Method: Research with documentary and local approach, inspired by the Dimension of Political History, to unveil power relations, political representations, symbols and discourses. Eighty-eight sources were used for the period 1997-2014. The data collection was performed in May 2016 and presented in the timeline modality. Results: The historical trajectory of the program indicates intersectoral and interinstitutional experience that has been increasing and originating important innovations in care to women based on humanization and from the perspective of comprehensiveness. Final considerations: Historicizing the Program contributed to the reflection on the construction of practices aimed at confronting violence, the need for intersectoral actions and looks that involve its complexity.

title: Technical efficiency analysis of marine shrimp farming (Litopenaeus vannamei) in biofloc and conventional systems: A case study in northeastern Brazil

description: Abstract Shrimp farming has a great ecological, economic, and social importance in northeastern Brazil. Although the conventional farming system is widely used, biofloc technology (BFT) system has been developed to reduce environmental impacts and optimizing the production. Thus,the present study evaluated the technical efficiency of production cycles of Litopenaeus vannamei in conventional and BFT systems.We analyzed 48 production cycles in the conventional system in 2013 and 2014 and 9 cycles in the BFT system in 2014 through data envelopment analysis (DEA). The inputs corresponded to the population density (post-larvae m-2), amount of feed (kg ha-1 cycle-1), labor (man ha-1) and power supply (HP ha-1), whereas the yield (kg ha-1 cycle-1) was considered the output. The results indicated four production cycles (7.0%) technically efficient, three in the conventional system and one in the BFT. By comparing the productive systems, there was significant difference in their mean scores of technical efficiency. There was a greater influence of the management inefficiency on the conventional system, while the production scale reduced the average scores of technical efficiency in the BFT system. These results may help to improve the development of sustainable L. vannamei farming in both systems by reducing waste and increasing profits.
