title: Salivary arginase activity after mechanical-chemical therapy

description: Abstract Introduction Salivary components can be used as biomarkers for diagnosing and monitoring oral diseases. There is evidence that one potential biomarker, arginase, is associated with the inflammatory processes of periodontal disease, and its enzymatic activity is reduced according to the improvement in the clinical parameters after treatment. Objective The present study aimed to evaluate the salivary arginase activity in gingivitis and periodontitis patients treated with full-mouth mechanical procedures combined with the adjunctive use of essential oils or chlorhexidine mouthwash, respectively. Material and method Twenty-six gingivitis and 16 periodontitis patients received complete periodontal examinations at the baseline and 3 months after therapy, in which the periodontal probing depth, clinical attachment loss, plaque index, and gingival index measurements were taken. At these same appointments, the salivary total protein level and salivary arginase activity were also established via spectrophotometry. Result There were improvements in all of the clinical parameters (p &lt; 0.05) evaluated from the baseline to 3 months in both groups. In addition, the salivary arginase activity and total protein levels were reduced after the gingivitis treatment. Conclusion Similar to the clinical results, both therapeutic protocols positively affected the salivary arginase activity; however, further studies are necessary to clarify its potential as a salivary biomarker for periodontal monitoring.

title: Implications of oral health in the functional area of elderly brazilians

description: Abstract Objective The objective of this study was to identify factors with a high degree of association with functional difficulty (DF) in the Brazilian elderly population, through the National Health Survey (PNS-2013). Material and method A cross-sectional, quantitative study with a data source from the PNS-2013, considering the total sample of individuals aged 60 or over (n = 23,815). For the analysis, two dependent variables were considered: Basic Activities of Daily Living and Instrumental Activities of Daily Living, and 30 independent variables related to sociodemographic and oral health conditions. The Waikato Environment for Knowledge Analysis software was used to perform the analyzes. Initially, the data set was balanced and the dimensionality reduction test was carried out, using the 10 Fold cross validation method. Finally, the variables related to the dependent variables were evaluated through logistic regression. Result The results point to the direct association between the DF of the elderly with: age aspects mainly for octogenarians (ABVD OR = 2.19 and AIVD OR = 2.82) and later, elderly without schooling (AIVD OR = 1.96), those who did not (AIVD OR = 1.65), and aspects of oral health, such as: presence of difficulty to feed due to problems with teeth or prostheses (ABVD OR = 1.73 and AIVD OR = 1.59), non-consultation with a dental surgeon throughout life (ABVD OR = 1.69) and absence of natural teeth (AIVD OR = 1.64). Conclusion Based on the findings, the importance of the strengthening of preventive strategies directed at the portion of individuals with 60 or more years, including oral health, is emphasized.

title: The Relational View: Future challenges for a non-confirmed expectation

description: Abstract Purpose: Despite its theoretical potential, the relational view proposed by Dyer & Singh (1998) has not been established as a dominant theoretical framework, since the concomitant use of its main constructs is rare. This paper intended to test the relational view considering the impact of its constructs on the economic value created in relationships between buyers and suppliers. Design/methodology/approach: A cross-sectional survey with 121 respondents was conducted in the Brazilian chemical sector. To analyze the measurement models and test the hypotheses, confirmatory factor analysis and multiple linear regression were used. Findings: The limited support for the hypotheses tested suggests that the operationalization of the relational view as an explanatory theory requires further study. Asset specificity seems to be the most solid construct, with a relevant effect on the relational value, and it is present in some moderating effects on environmental variables. The results also suggest that relational governance has some effect on the value captured by the supplier. Originality/value: In addition to the need to review the operationalization of the Relational View, the proposed value measurement model contributed to identifying differences between the value created for the buyer and the value created for the supplier. The measurement scales of value creation presented good quality of fit and also represent a contribution for further research.

title: Bluetongue disease in sheep: a review

description: ABSTRACT The present review aims to show the main aspects related to bluetongue virus (BTV) infection in sheep. The bluetongue (BT) is a viral, infectious, and non-contagious disease caused by a virus (BTV) of the Orbivirus genus, transmited by a hematophagous vector of the Culicoides genus, to domestic and wild ruminants, mainly to sheep, the most susceptible species. It is caused by the association of endemic with climate conditions, with high temperatures and humidity. Economic loss is directly linked to death, abortion, weight loss, loss of milk, and meat production, and, indirectly, to the restriction on the export of animals and their by-products. The study concludes that the BTV is worldwidely spread, and probably persists due to the warm and humid climate that leads to the proliferation of Culicoides sp., being necessary to adopt measures that reduce the risk factors associated to the BTV infection.

title: TEACHING HISTORY OF EDUCATION: THOUGHTS AROUND A PROPOSAL

description: Abstract The aim of this work is to present a reflection on the teaching of the History of education from the perspective of the capture of decisions for the formulation of a program of study on the above mentioned discipline. The reflection relies on theoretical developments from the historiography of the History of the education and experiences at university teaching in the last 20 years. The work departs from some foundational problems from the History of education and advances on them by offering a teachig proposal. The proposed scheme considers the potentials that each of the historiographical stages have to offer for such a proposal. Likewise, it stands out t internationalization as a particular moment of the contemporary debate that can occupy the place of liason between the problem of researching and teaching inside a program of study.

title: A new approach towards the so-called recalcitrant seeds

description: ABSTRACT: Water is essential, irreplaceable, and indispensable for any kind of carbon-based-life metabolic activity. Water-dependent living beings are the expected pattern in nature. However, some organisms can survive for some time at a minimum water content, such as seeds of some species (orthodox seeds). Nevertheless, the expected standard life behavior is found in seeds of another group of species, the so-called recalcitrant seeds, which are sensitive to desiccation. A huge range of different behaviors can be found between these two groups, leading authors to consider that orthodoxy and recalcitrance is not an all-or-nothing situation. Notwithstanding, we are still too far from understanding the differences and similarities between all these kinds of seeds and this has been a serious barrier to the development of plant conservation technologies. A new approach to understanding the differences between these seeds is presented here based on seed maturation, environmental influences, and evolution. From this point of view, all kinds of seed behavior are contemplated and, consequently, some new perspectives are considered for the recalcitrant seed conservation technology, the most intensely desired technology nowadays in this area.

title: Sodium dodecyl sulfate as a viral inactivator and future perspectives in the control of small ruminant lentiviruses

description: ABSTRACT Infections by small ruminant lentiviruses (SRLVs) affect goats and sheep causing chronic multisystemic diseases that generate great economic losses. The caprine lentivirus (CLV) and the ovine lentivirus (OLV) present tropism for cells of the monocyte/macrophage lineage, which are directly associated with the main route of transmission through the ingestion of milk and colostrum from infected animals. In this manner, controlling this route is of paramount importance. Currently, researches have investigated the use of chemical additives in milk that can preserve colostrum or milk and inactivate microbiological agents. Among the compounds, sodium dodecyl sulfate (SDS) has been shown to be satisfactory in the chemical inactivation of HIV and CLV in milk, and also as a biocide in goat colostrum.

title: Curcuma Longa Abolishes Phenylephrine-Induced Contractions in Isolated Aortic Artery of Rats

description: Abstract Background: Curcuma longa has biological effects. Its cardiovascular activities are yet to be scientifically studied. Objectives: To investigate the vasorelaxant effects of the aqueous extract of Curcuma longa (AECL). Methods: Aortic annuli of normotensive rats, with or without endothelium, were set up in a data storage system with nutrient solution in recipients, with scientifically recommended temperature, aeration and tension. Over contraction by Phenylephrine, the AECL (1, 3, 10, 30, 100, 300 and 1000 µg/mL) was incubated before and after incubation with atropine or L-name or indomethacin. An AECL concentration-response curve was also built over contractions caused by elevation of extracellular K+. Data were significant when p &lt; 0.05, with GraphPad Prism 6.0 software resolutions. Results: The AECL induced 100% vasorelaxation also in the endothelium-free annuli. The part of the endothelium-dependent effect had EC50 = 4.32 ± 0.05 µg/mL. With inhibition of NO production, the EC50 increased to 126.50 ± 2.35 µg/mL; after inhibition of prostacyclin production, to 124.6 ± 0.05 µg/mL; and after muscarinic blockade, to 437.10 ± 0.2 µg/mL. Opening of K+ channels (relaxation of 56.98%) and VOCC blockade (relaxation of 31.56%) were evident. Conclusion: AECL induced significant vasorelaxation, being more significant in the presence of endothelium. The muscarinic pathway seems to be the main one involved in this effect, followed by the NO production and prostacyclin pathways. The activity in K+ channels by AECL was more significant than its VOCC blockade. The use of other models and tools to study action mechanisms will be important and elucidating.

title: Water stress in germination, growth and development of coffee cultivars

description: Abstract: The aim of this study was to evaluate the effect of water stress on the germination of Coffea arabica seeds and the growth and development of plants from these seeds. Seeds of the cultivars Bourbon Vermelho, Mundo Novo, and BA-10 were placed to germinate in the dark at 30 ºC in the presence and absence of 100 g/L of polyethylene glycol 6000. The water stress applied delayed the beginning of seed germination by seven days in relation to seeds of the control, which had achieved responses of up to 50%, but there were no differences between the treatments at the end of the experiment. Furthermore, the length of the primary root in seeds germinated under water stress was less than in the control treatment, especially for the cultivar Mundo Novo. Plants of the cultivars Bourbon Vermelho and Mundo Novo developed from seeds previously germinated under water stress exhibited reduced height and fewer leaf pairs than those from the control, whereas ‘BA-10’ responded in a similar way in both treatments. Thus, the cultivars Bourbon Vermelho and Mundo Novo were more sensitive to the water stress applied in the germination phase than ‘BA-10’.

title: Synanthropic diptera affecting layer poultry farms: a review

description: ABSTRACT: The poultry farm of posture is an economic activity of great relevance to Brazil. Health aspects of flocks of laying chickens, such as the occurrence of infestations by parasites and poultry pests, influence significantly the productivity indicators. In this context, the control of synanthropic diptera is one of the challenges of the poultry farmers and professionals of this area. In Brazil, the control of flies in poultry environments is based mainly on the use of pesticides, while other alternatives are less frequent. Among the flies’ species most regularly found in poultry farms are the Musca domestica, Chrysomya spp., Fannia spp., and others. This review aims at compiling the literature on the occurrence, impact on poultry systems, biology, epidemiology and control of the species of synanthropic flies considered important for the Brazilian poultry industry.

title: AGRO-CLIMATIC SUITABILITY AND WATER REQUIREMENT FOR TANZANIA GUINEAGRASS CULTIVATION IN THE STATE OF CEARÁ

description: ABSTRACT This study aimed to define areas suitable, and the irrigation water requirement for, cultivation of Tanzania guineagrass in the state of Ceará, Brazil. Tanzania guineagrass yield was estimated by a mathematical model, which considers the crop actual evapotranspiration, resulting from the crop climatological water balance. The water requirement throughout the year was estimated for soils with a water holding capacity of 20 (shallow soils), 40 (sandy soils), 60 (soils with medium texture) and 100 mm (clay soils). The relative frequency of occurrence of monthly productions greater than 2,750 kg DM ha-1 month-1 was obtained for different areas in Ceará, representative of most of the state's economic mesoregions. Tanzania guineagrass annual yields in the state of Ceará were between 20,000-30,000 kg DM ha-1 year-1. During the rainy season, the productive potential varies with the economic mesoregion, which presents different climatic conditions. The state of Ceará is only suitable for the rainfed production of Tanzania guineagrass for 4 months each year, predominantly from February to May, while weather conditions do not favor the development of this grass in the remaining months.
