MAPA BRASIL AFROTECH

The Brasil Afrotech Map is developed based on the proposition of visibility of professors, researchers and their respective research projects. The methods in this work are based on applications that use software related to digital media. The basic premise arises from the lack of information related to the dissemination of academic and research projects, in this case, in the academic field of Afro-descendent. The result demonstrate the participation and/or coordination – of scientists, teachers and researchers of Afro-descendent in university institutions, innovation or technological development, in Brazilian organizations.El Mapa Brasil Afrotech se desarrolla a partir de la propuesta de visibilidad de los docentes, investigadores y sus respectivos proyectos de investigación.

RESPOTA DO FUNGO MICORRÍZICO ARBUSCULAR RHIZOPHAGUS CLARUS E ADIÇÃO DE SUBSTÂNCIAS HÚMICAS NO CRESCIMENTO DO TOMATEIRO

A utilização de fungos micorrízicos arbusculares (FMAs) pode otimizar a produção, uma vez que a simbiose entre o fungo e a planta pode promover o aumento da absorção de nutrientes. O objetivo deste estudo foi avaliar o efeito da inoculação de fungo micorrízico arbuscular e a adição de substâncias húmicas (SHs) na cultura do tomateiro. Para isso, foram avaliados: a densidade dos esporos, a colonização radicular por FMA, a produção de fitomassa, o índice de clorofila e o conteúdo de fósforo na parte aérea. O delineamento experimental foi inteiramente casualizado com quatro tratamentos e cinco repetições em vasos com 3 L de substrato (areia + vermiculita 1:1 v/v, estéril) em casa de vegetação da Universidade Paranaense – UNIPAR, Umuarama, PR. Os tratamentos foram os seguintes: 1 - sem inoculação de FMA e sem adição de SHs, 2 - com inoculação de FMA e sem adição de SHs, 3 - sem inoculação de FMA e adição de SHs, 4  - com inoculação de FMA e adição de SHs. A densidade de esporos, a colonização radicular por FMA, a massa seca da parte aérea e total e o conteúdo de fósforo das folhas foram aumentados significantemente com a inoculação de FMAs e adição de SHs. O índice de clorofila aumentou significantemente a adição de SHs. Conclui-se que com a inoculação de FMAs e adição de SHs promove o crescimento e o aumento do conteúdo de fósforo na planta de tomateiro

Mineral and organomineral sources of nitrogen to maize agronomic performance

Nitrogen (N) is one of the nutrients absorbed in great quantity by maize crop. Also, N fertilizers are of high costs and subject to large losses into the agricultural environment. There are various categories of fertilizers known as fertilizers of improved efficiency that can minimize such N losses. The objective of this study was to evaluate the effect of different sources and doses of N in maize agronomic performance. The experiment was installed in randomized blocks, with four replications, designed as a factorial 5 x 5 + 1, constituted by five N sources (urea, urea polymerized, urea with NBPT, organomineral with and without NBPT), five N doses (40, 80, 120, 160, 200 kg ha-1) plus a control (no N supply). The chlorophyll contents and grain yield were evaluated. The results showed no differences for the different N sources, indicating that the organomineral sources are as efficient as the mineral sources. The addition of N fertilizers in increasing doses, regardless of the source tested, has increased the levels of chlorophylls and grain yiled

ATLANTIC EPIPHYTES: a data set of vascular and non-vascular epiphyte plants and lichens from the Atlantic Forest

Epiphytes are hyper-diverse and one of the frequently undervalued life forms in plant surveys and biodiversity inventories. Epiphytes of the Atlantic Forest, one of the most endangered ecosystems in the world, have high endemism and radiated recently in the Pliocene. We aimed to (1) compile an extensive Atlantic Forest data set on vascular, non-vascular plants (including hemiepiphytes), and lichen epiphyte species occurrence and abundance; (2) describe the epiphyte distribution in the Atlantic Forest, in order to indicate future sampling efforts. Our work presents the first epiphyte data set with information on abundance and occurrence of epiphyte phorophyte species. All data compiled here come from three main sources provided by the authors: published sources (comprising peer-reviewed articles, books, and theses), unpublished data, and herbarium data. We compiled a data set composed of 2,095 species, from 89,270 holo/hemiepiphyte records, in the Atlantic Forest of Brazil, Argentina, Paraguay, and Uruguay, recorded from 1824 to early 2018. Most of the records were from qualitative data (occurrence only, 88%), well distributed throughout the Atlantic Forest. For quantitative records, the most common sampling method was individual trees (71%), followed by plot sampling (19%), and transect sampling (10%). Angiosperms (81%) were the most frequently registered group, and Bromeliaceae and Orchidaceae were the families with the greatest number of records (27,272 and 21,945, respectively). Ferns and Lycophytes presented fewer records than Angiosperms, and Polypodiaceae were the most recorded family, and more concentrated in the Southern and Southeastern regions. Data on non-vascular plants and lichens were scarce, with a few disjunct records concentrated in the Northeastern region of the Atlantic Forest. For all non-vascular plant records, Lejeuneaceae, a family of liverworts, was the most recorded family. We hope that our effort to organize scattered epiphyte data help advance the knowledge of epiphyte ecology, as well as our understanding of macroecological and biogeographical patterns in the Atlantic Forest.

Museu da Língua Portuguesa: uma etnografia da interatividade em seu modelo de difusão cultural

Doutoramento em Ciências da CulturaO Museu da Língua Portuguesa - MLP é uma referência em difusão cultural desta língua, no Brasil, enquanto patrimônio cultural imaterial. Instalado num prédio construído no século XIX para tornar-se o principal eixo modal de transporte ferroviário de São Paulo, a Estação da Luz, revitalizada e tombada como patrimônio histórico, após intensa atividade de restauro, passou a abrigar este projeto cultural. O museu encontra receptividade e reconhecimento de público e alcança elevados índices de visita. Nestas circunstâncias, a investigação visa perscrutar as dinâmicas de interatividade comunicativa no MLP, em função de suas interfaces, a citar a relação entre o visitante e os seus acervos, constituídas neste caso por instalações tecnológicas e mídias interativas. Os aportes de métodos como a entrevista, a aplicação de instrumento de coleta de dados, em formato de questionário e análise qualitativa, a pesquisa em documentos e publicações do museu, as anotações em caderno de campo, carreiam técnicas que se incorporam à metodologia etnográfica de observação participante, eixo estruturante e suporte investigativo a este projeto, no campo das ciências da cultura. O período de investigação, entre julho de 2012 e novembro de 2015, pressupõe uma análise de contexto, a considerar a conjuntura social, política e cultural que repercute para criação do museu, em 2006, e referências distintivas entre a cultura brasileira e a portuguesa, as quais também perpassam à língua como componente de projeto curatorial. Enfim, compreender a dinâmica entre o acervo e as instalações tecnológicas e, nesta imbricação, se o modelo de interatividade proposto se coaduna à expectativa do visitante, configura o cerne da investigação.The Museum of the Portuguese Language - MPL is a reference in cultural diffusion of the Portuguese language, in Brazil, as intangible cultural heritage. Housed in a building built in the nineteenth century to become the main axis of modal railway in São Paulo, the Estação da Luz, was revitalized and listed as historical heritage after intensive restoration activity, and now houses this cultural project. The museum has receptivity and public recognition and achieves high levels of visits. In these circumstances, the research aims to scrutinize the dynamics of communicative interaction in the MPL, according to its interfaces, quoting the relationship between the visitor and its collections, constituted in this case by technological installations and interactive media. The contributions of methods such as the interview, the application of data collection instrument in questionnaire format and qualitative analysis, research documents and museum publications, the notes in a field diary, foment techniques that incorporate the ethnographic methodology participant observation, structural axis and investigative support to this project, in the field of culture sciences. The reporting period, between July 2012 and November 2015, presupposes a context analysis, to consider the social situation, political and cultural repercussions for the museum’s creation in 2006, and distinctive references between Brazilian culture and the Portuguese, which also permeate the language as a curatorial project component. Finally, understanding the dynamics between the collections and the technological installations, and in this imbricate, the proposed model of interactivity in line with visitor expectations, sets the core of the research

Resposta do fungo micorrízico arbuscular Rhizophagus clarus e adição de substâncias húmicas no crescimento do tomateiro (Solanum lycopersicum L.)

The utilization of arbuscular mycorrhizal fungi (AMF) can improve plant production, due the symbiosis between the fungus and plants can promote the increasing of nutrient uptake. This study aimed to evaluate the effect of AMF inoculation and the addition of humic substances (HSs) in tomato cultivation. For this, it has been analyzed the density of spores and the root colonization by the AMF, phytomass’ production, the chlorophyll index and the content of phosphorus of aerial part. The experiment has been fully made with four treatments and five repetitions in three-litter-pot of substrate (sand + vermiculite 1:1 v/v, sterile) in the greenhouse at Universidade Paranaense – UNIPAR in Umuarama, Paraná State. The treatments have been the following: 1 – with no inoculation of AMF and with no addiction of HSs, 2 – with inoculation of AMF and with no addiction of HSs, 3 – with no inoculation of AMF and addiction of HSs, 4 – with inoculation of AMF and addiction of HSs. The density of spores and the radicular colonization by AMF, the dry mass of aerial part and total, the content of phosphorus in aerial part, have increased significantly with the inoculation of AMF and addiction of HSs. The chlorophyll index has increased significantly the addiction of SHs. Concluded that the inoculation of AMF and addiction of HSs it promotes the growth and the increase of phosphorus content in the tomato plantA utilização de fungos micorrízicos arbusculares (FMAs) pode otimizar a produção, uma vez que a simbiose entre o fungo e a planta pode promover o aumento da absorção de nutrientes.

Cry1Ac and Vip3Aa proteins from Bacillus thuringiensis targeting Cry toxin resistance in Diatraea flavipennella and Elasmopalpus lignosellus from sugarcane

The biological potential of Vip and Cry proteins from Bacillus is well known and widely established. Thus, it is important to look for new genes showing different modes of action, selecting those with differentiated entomotoxic activity against Diatraea flavipennella and Elasmopalpus lignosellus, which are secondary pests of sugarcane. Therefore, Cry1 and Vip3 proteins were expressed in Escherichia coli, and their toxicities were evaluated based on bioassays using neonate larvae. Of those, the most toxic were Cry1Ac and Vip3Aa considering the LC50 values. Toxins from E. coli were purified, solubilized, trypsinized, and biotinylated. Brush Border Membrane Vesicles (BBMVs) were prepared from intestines of the two species to perform homologous and heterologous competition assays. The binding assays demonstrated interactions between Cry1Aa, Cry1Ac, and Vip3Aa toxins and proteins from the BBMV of D. flavipennella and E. lignosellus. Homologous competition assays demonstrated that binding to one of the BBMV proteins was specific for each toxin. Heterologous competition assays indicated that Vip3Aa was unable to compete for Cry1Ac toxin binding. Our results suggest that Cry1Ac and Vip3Aa may have potential in future production of transgenic sugarcane for control of D. flavipennella and E. lignosellus, but more research is needed on the potential antagonism or synergism of the toxins in these pests

Tc-99m-sestamibi scintigraphy used to evaluate tumor response to neoadjuvant chemotherapy in locally advanced breast cancer: A quantitative analysis

To evaluate the tumor response to neoadjuvant chemotherapy, Tc-99m-sestamibi breast scintigraphy was proposed as a quantitative method Fifty-five patients with ductal carcinoma were studied They underwent breast scintigraphy before and after neoadjuvant chemotherapy, along with clinical assessment and surgical specimen analysis The regions of interest on the lesion and contralateral breast were identified, and the pixel counts were used to evaluate lesion uptake in relation to background radiation The ratio of these counts before to after neoadjuvant chemotherapy was assessed The decrease in uptake rate due to chemotherapy characterized the scintigraphy tumor response The Kruskal-Wallis test was used to compare the mean scintigraphic tumor response and histological type Dunn's multiple comparison test was used to detect differences between histological types The Mann-Whitney test was used to compare means between quantitative and qualitative variables scintigraphic tumor response vs clinical response and uptake before chemotherapy vs scintigraphic tumor response The Spearman's test was used to correlate the quantitative variables of clinical reduction in tumor size and scintigraphic tumor response All of the variables compared presented significant differences The change in Tc-99m-sestamibi uptake noted on breast scintigraphy, before to after neoadjuvant chemotherapy, may be used as an effective method for evaluating the response to neoadjuvant chemotherapy, since this quantification reflects the biological behavior of the tumor towards the chemotherapy regimen Furthermore, additional analysis on the uptake rate before chemotherapy may accurately predict treatment respons
