title: Dual-task during gait between elderly with mild cognitive impairment and Alzheimer: systematic review

description: Abstract Introduction: Studies report that mobility changes could be present in early stages of Alzheimer’s disease (AD) or even in previous stages, such as mild cognitive impairment (MCI). The use of motor tests, involving dual task, could facilitate screening and differentiation between elderly with AD and MCI. Objective: to verify if gait tests associated with secondary tasks could differentiate elderly with AD and MCI. Methods: We conducted a systematic review in Pubmed, Web of Science, Medline and Scielo databases. Of the articles included, we collected information about year of the study, characteristics of the sample and the dual task test studied. Results: The databases were accessed during November 2014 and August 2015 and a total of 198 scientific papers was obtained. After reading first the summaries and then the full texts, five studies were inserted in the review. Elderly with AD presented a reduction of gait speed and stride length, using executive functions and countdown as secondary cognitive tasks. The type of MCI appears to influence the differentiation with AD. Conclusion: The review showed that some gait tests associated with a secondary task differentiate elderly with AD and MCI. It emphasizes the need of new studies involving this issue in order to obtain cut-off points and facilitate prevention, early diagnosis and observation of cognitive impairment’s evolution in clinical practice of elderly.

title: AGENDAS, PREFERENCES, COMPETITION: PT and PSDB in presidential disputes

description: In the Brazilian political science, there is a debate about the bipolarization of the party system resulting from the concentration of the competition in the presidential elections in two parties: PT and PSDB. This article aims to identify the content and the terms of competition among such parties concerning their thematic emphasis by comparing government plans of each party for the presidential elections from 2006 to 2014. The hypothesis, derived from saliency theory, is that the competition between them is based on the selection of specific themes and alternative agendas. The method used to measure agendas and preferences is the content analysis, applying the categories of the Manifest Research Group – MARPOR. The results reveled that platforms come closer to each other due to the inclusion of themes of the national public agenda, but they are distinguished in the priorities that each party establish and in the direction in which they adapt their emphases over time.

title: Photosynthetic capacity and water use efficiency in Ricinus communis (L.) under drought stress in semi-humid and semi-arid areas

description: ABSTRACT Castor bean is one of the crops with potential to provide raw material for production of oils for biodiesel. This species possess adaptive mechanisms for maintaining the water status when subjected to drought stress. A better understanding these mechanisms under field conditions can unravel the survival strategies used by this species. This study aimed to compare the physiological adaptations of Ricinus communis (L.) in two regions with different climates, the semi-arid and semi-humid subject to water stress. The plants showed greater vapor pressure deficit during the driest hours of the day, which contributed to higher values of the leaf temperature and leaf transpiration, however, the VPD(leaf-air) had the greatest effect on plants in the semi-arid region. In both regions, between 12:00 p.m. and 2:00 p.m., the plants presented reduction in the rates of photosynthesis and intracellular CO2 concentration in response to stomatal closure. During the dry season in the semi-arid region, photoinhibition occurred in the leaves of castor bean between 12:00 p.m. and 2:00 p.m. These results suggest that castor bean plants possess compensatory mechanisms for drought tolerance, such as: higher stomatal control and maintenance of photosynthetic capacity, allowing the plant to survive well in soil with low water availability.

title: Troubled conversations: dialogues about ethnographic collections with the Ka’apor indigenous people

description: Abstract This article discusses the collaborative research and exhibition project Sharing Collections and Connecting Histories, carried out by the National Museum of Ethnology in Leiden (NME), the Netherlands, the Museu Paraense Emílio Goeldi, Brazil and the Ka’apor indigenous people of the indigenous reserve Alto Turiaçu, Maranhão, Brazil. The collaborative approach that characterized this project reflects a transformation that has been taking place at the NME in Leiden towards a more inclusive and collaborative museological work, and at the Museu Goeldi, which has been promoting collaborative work with indigenous peoples for at least two decades. The project seeks to meet the political needs of the Ka’apor to draw national and international attention to the importance of defending their territorial rights, which are continuously threatened by the illegal exploitation of lumber on their land. This article focuses on the dialogical processes of studying the Ka’apor collections and developing an exhibition. It considers different disciplinary foci — anthropology and museology — in dialogue with indigenous thought, as well as the process of negotiating the interests and the encounters between different cognitive perspectives and political positions. In addition to documenting and reflecting on the co-creative production of an ethnographic exhibition, this article reconsiders the cognitive, political and ethical dimensions of this type of work involving indigenous peoples.

title: ETHANOL AND NITRIC OXIDE IN QUALITY MAINTENANCE OF ‘GALAXY’ APPLES STORED UNDER CONTROLLED ATMOSPHERE

description: ABSTRACT The aim of this work was to evaluate the effect of ethanol and two nitric oxide dose applications on the maintenance of the post-storage quality of ‘Galaxy’ apple during storage under controlled atmosphere (CA). Treatments evaluated were: [1] 1.2 kPa O2 + 2.0 kPa CO2; [2] CA + 20 µL L-1 of nitric oxide, [3] CA + 40 µL L-1 of nitric oxide; [4] CA + 1 ml of ethanol kg-1 fruit. Fruits received treatments before storage and were kept under CA during eight months and seven days of storage at 20 °C. Fruits had been kept on CA for eight months and seven days at 20° C. Fruits treated with ethanol showed higher ethylene production, low flesh firmness, high flesh breakdown, mealiness and acetaldehyde production. Fruits treated with 40 µL L-1 nitric oxide showed lower ethylene production, respiration rate and ACC oxidase ( (1-aminocyclopropane-1-carboxylic acid) oxidase enzyme activity. Apples treated with 20 uL L-1 nitric oxide showed higher ethylene production, respiration rate, internal ethylene concentration CO2 and ethanol concentration. Ethanol and nitric oxide application before storage have no benefits in maintaining fruit quality after storage under CA due to lower flesh firmness, higher mealiness incidence, flesh breakdown and decay incidence.

title: The conservation of native priority medicinal plants in a Caatinga area in Ceará, northeastern Brazil

description: ABSTRACT Much of the Brazilian semiarid region faces a considerable process of degradation of natural resources, and ethnobotanical studies have collaborated with important information about the use and traditional knowledge, serving as a tool to design conservation strategies of native plant species. Thus, this study aimed to determine medicinal species meriting conservation priorities in a “Caatinga” area in the northeastern of Brazilian territory. The ethnobotanical data were collected through semi-structured interviews with key subjects selected through the “snowball” technique. The availability and species conservation priority was verified by relative density, risk of collection, local use and use of diversity in the forest fragment sampled. It was recorded 42 native medicinal plants and conservation priority score was calculated for seven species, including Mimosa tenuiflora, Hymenaea courbaril, Ximenia americana and Amburana cearensis need immediate conservation and attention, since their collection does not occur in a sustainable way. In order to ensure the perpetuation of the species and the sustainability of traditional therapeutic practice there needs to be a development of conservation practices of caatinga remaining to better conserve the species of the biome.

title: Selenium behavior in the soil environment and its implication for human health

description: ABSTRACT Selenium (Se) is an important element that was discovered in 1817, and since the 1960s, it has been regarded as an essential micronutrient for both animals and humans, playing among other functions a relevant role in the antioxidant system of mammals. Inadequate blood Se levels in the human body is a well-known concern in many parts of the world. This malnutrition problem is often due to Se-poor diet, probably as a result of the low Se availability in soils where crops are growing. Nowadays, it is known that not only the total content, but also the inorganic and organic forms of Se contained in foods are important for human nutrition. However, paradoxically some regions of the world present high Se levels in soils causing several functional disorders and diseases in people who live in seleniferous areas. As essential micronutrient, Se should be supplied in controlled amounts to avoid harmful effects. Therefore, taking into account the importance of the soils as a way to ensure the adequate Se supply for the population, this review has dealt with Se behavior in soil environment (e.g., Se forms and adsorption and desorption reactions) and its relevance for the human health. As a final message, the further understanding of Se behavior in soils to predict its availability for crops in different systems will be a significant approach in future studies to establish forms and safe doses of Se to be added in fertilizers. Agronomic and genetic biofortification of staple crops with Se has been suggested as an important tool to improve Se intake by population in Se-poor sites.
