title: Is there any association between vitamin D levels and polycystic ovary syndrome (PCOS) phenotypes?

description: ABSTRACT Objective The aim of this study was to assess the serum vitamin D level in a retrospective study in women with polycystic ovary syndrome (PCOS), according to the different phenotypes of the disease. Subjects and methods In this retrospective study, the records of 351 infertile women who were diagnosed with PCOS were examined, and 200 of them were enrolled in the study randomly in 4 PCOS phenotypes. Fifty normal ovulatory women with the history of male factor were selected as the control group. Parameters, including age, infertility duration, body mass index (BMI), hormone profile, as well as the serum vitamin D level were compared among the 4 phenotypes, with the P-value ≤ 0.05 considered statistically significant. Results The findings showed a higher serum vitamin D level in the control group than in PCOS patients, which was statistically significant (P &lt; 0.001). In addition, there was no significant difference in the serum vitamin D level among the four phenotypes of PCOS. Conclusions No significant difference was found in the serum vitamin D level of the different phenotypes of PCOS. Further studies with larger sample sizes are recommended to be done to establish the role of the serum vitamin D level in PCOS patients.

title: WATER AVAILABILITY IN A PLANOSOL UNDER INTEGRATED CROP-LIVESTOCK-FORESTRY SYSTEM IN THE AGRESTE REGION OF PARAIBA, BRAZIL

description: ABSTRACT Integrated agricultural production systems, involving agriculture, livestock, and forest are strategies that improve soil quality. The objective of this work was to evaluate the effect of the integrated crop-livestock-forest system (ICLF) on water availability of a Planosol in the Agreste region of the state of Paraíba (PB), Brazil. The experiment was conducted at the experimental site of the Agricultural Research Company of Paraíba (EMEPA), in Alagoinha, PB. The soil evaluated was a Eutric Planosol, with a moderate A horizon. The following intercrops (treatments) were implemented in June 2015: I. Gliricidia sepium + Brachiaria decumbens; II. Mimosa caesalpiniifolia + Brachiaria decumbens; III. Tabebuia alba + Brachiaria decumbens; IV. Zea mays + Brachiaria decumbens; and V. Brachiaria decumbens. A randomized block experimental design was used, with five treatments. The analyzed variables were field capacity, permanent wilting point, soil available water, granulometry, degree of flocculation, total porosity, macroporosity, microporosity, saturated hydraulic conductivity, resistance to penetration, and aggregate stability index. The results showed that the water availability in the ICLF implemented in the Agreste region of Paraíba had no significant variation after three years. After the three-year period, the ICLF promoted no significant physical improvement in the attributes of the evaluated Planosol.

title: Different cooking styles enhance antioxidant properties and carotenoids of biofortified pumpkin (Cucurbita moschata Duch) genotypes

description: Abstract Biofortification is an important technique where the nutritional quality of food crops is enriched through the increase of nutrient content. Provitamin A deficiency is still a public health concern mainly in developing countries. Since beta-carotene is a vitamin A precursor, the increase of this compound in foods through biofortification is a manner to reach people under hidden hunger condition. This work aimed to evaluate the effect of different cooking styles on carotenoids content and antioxidant activity of two different genotypes of biofortified Cucurbita moschata. In the present study, biofortified pumpkins submitted to different cooking conditions were assessed for antioxidant activity by ABTS, DPPH, β-carotene/linoleic acid systems and have polyphenols and carotenoids content compared. The cooking style affected the antioxidant activity. Pumpkins from genotype 1 showed high levels of carotenoids, α-carotene and all-E-β-carotene compared to samples from genotype 2. There was an increase of all carotenoids in both cooked pumpkins, and steam cooking showed the highest retention percentages. Steam cooking presented a higher percentage of carotenoid retention. Pumpkin consumption in developing countries, especially in the Northeast Brazil may be promoted to combat vitamin A deficiency.

title: Julius Kaiser's analytic-synthetic method: Pioneering for the subject approach to information

description: Abstract The development of the analytic-synthetic method, normally attributed to S. R. Ranganathan , had its initial foundation defined in the systematic indexing developed by J. Kaiser at the beginning of the 20th century, some two decades prior to the appearance of the faceted classification. This study aims to support the proposition that by combining the philosophical principle of categorization (for analysis) with the pragmatic logic of indexing of subjects (for synthesis), as Kaiser elaborated his form of indexing, he conceived the underpinning bases for the analytic-synthetic method. The theoretical table which subsidized the study is comprised of the bibliography pertinent to the subject approach to information, particularly regarding bibliographic classifica tion, subject cataloguing and indexing. Using William James's pragmatism as our methodological approach, we investigated how the procedural systematics of Kaiser's indexing method emerges as a forerunner to the analytic-synthetic method. The fundamental elements of the investigation were the analysis of components, conduction of analysis, synthesis and products of the synthesis, thus including the analytic and synthetic dimensions of the works carried out by Kaiser and Ranganathan.

title: Detection of agents associated with respiratory diseases of swine by real time PCR

description: Porcine Respiratory Disease Complex (PRDC) is a group of diseases that cause high losses in the swine industry. Several infectious agents are related to PRDC including porcine circovirus 2 (PCV-2), pseudorabies virus (SuHV-1),Haemophilus parasuis (HP), Mycoplasma hypneumoniae (MH) and Pasteurela multocida (PM). The aim of this study was to develop real-time PCRs (qPCR) for the detection of these infectious agents. Oligonucleotides were designed for each specific infectious agent and labeled with different fluorophores to amplify specific parts of the genome. This was done in two groups of reactions—a duplex qPCR for SuHV-1 and PCV-2 and a multiplex qPCR to detect the three bacteria simultaneously. The reactions were tested in 142 pooled samples of swine lymph nodes and lungs with clinical signs of PRDC. There were 135 samples that tested positive for PCV-2, 61 for HP, 29 for PM, 30 for MH and zero for SuHV-1. We recorded 76 cases of co-infection. The qPCRs developed in this study are useful tools in the diagnosis of PRDC.

title: Wikipedia as a source of monolingual and multilingual information about the Spanish heritage

description: Abstract The aim of the study was to analyze the online encyclopaedia Wikipedia as a tool for the dissemination of monolingual and multilingual information about the Spanish heritage. The sample consists of catalogued buildings and sites of cultural interest in a Spanish region. For that purpose, we examined to what extent articles about the buildings and sites are represented in Wikipedia that is, what kind of information is dedicated to each of them. Three different types of search in the encyclopaedia (browsing, lists and internal search engine) were performed for several months. In addition, we established to what extent Wikipedia includes multilingual information regarding the sample, that is, the number of languages in which the information is expressed, as well as articles translated into languages other than Spanish. The results show that only 21.73% of the buildings and sites that constitute the final sample have a separate article in Wikipedia, of which only 20.85% are in several languages, and 50.00% are properly described as translations. This leads us to conclude that, given the collaborative nature of this tool and in view of the cultural and economic importance of historical and cultural heritage, institutions should be responsible for promoting the multilingual dissemination of this type of information.

title: EMERGENCE, GROWTH AND PRODUCTION OF SESAME UNDER SALT STRESS AND PROPORTIONS OF NITRATE AND AMMONIUM

description: ABSTRACT In arid and semi-arid regions, the quality of irrigation water varies in geographic terms and during the year, and the occurrence of water with high concentrations of salts is common. In this context, this study aimed to evaluate the emergence, growth and production of sesame, cultivar CNPA G3, irrigated with saline water and fertilized with N of different carrier proportions by the ratio of nitrate and ammonium ( NO --N and NH +-N) in an experiment conducted in lysimeters arranged in a greenhouse in the municipality of Campina Grande-PB, Brazil. The treatments were distributed into randomized blocks using a 5 × 5 factorial scheme relative to levels of irrigation water salinity (ECw; 0.6, 1.2, 1.8, 2.4 and 3.0 dS m-1) and five proportions of NO3 -N/NH4 -N (200/0; 150/50; 100/100; 50/150 and 0/200 mg of N kg-1), with three replicates. The increase in ECw compromised the emergence, growth and production of sesame, cultivar CNPA G3, and the production components were the most sensitive variables. The highest growth in diameter was obtained with the proportion of 200/0 mg kg -1 of NO3 -N/NH4 -N. An ECw level of 3.0 dS m and fertilization with 0/200 mg kg of NO3 -N/NH4 -N promoted deleterious effects on the total mass of sesame fruits and mass of seeds. The interaction between water salinity levels and NO3-/NH4 proportions significantly affected the number of leaves (at 50 and 70 days after sowing), the total mass of fruits and the mass of seeds.

title: Finding the water refractive index in a swimming pool using a ruler

description: Abstract When a swimming pool is filled with water, the tiles covering its walls appear to have smaller vertical dimensions than the real ones, due to the refraction of light from the water into the air. This condition was used to find the refractive index of water, using a trigonometric equation developed from a geometrical model. The necessary measurements were made with a common ruler and the average value obtained for the refractive index was very close to the real one, favoring the didactic potential of this experimental activity.
