Canopy temperature of bean genotypes under two soil humidity conditions

Foram avaliadas, de hora em hora, entre as 7h e as 17h, durante três dias consecutivos, as temperatura das folhagens dos genótipos de feijão (Phaseolus vulgaris L.) Bat-66, Bat-70 e G-3776, submetidos a condições ótimas de umidade e deficiência hídrica, utilizando-se a técnica da termometria infravermelha, em ambiente de casa de vegetação. Observou-se que as temperaturas dos genótipos foram mais elevadas quando estes se encontravam sob condições de deficiência hídrica do que quando sob condições ótimas de umidade. Entretanto, Bat-70 obteve uma temperatura mais baixa quando sob deficiência hídrica do que Bat-66 e G-3776. Foi sugerida a possibilidade de utilização da temperatura da folhagem para detectar deficiência hídrica em culturas e na seleção inicial de genótipos de feijão tolerantes à seca.Canopy temperatures of Bat-66, Bat-70 and G-3776 bean (Phaseolus vulgaris L.) genotypes submitted to well-watered and water deficiency conditions were evaluated hourly between 7:00 A.M. and 5:00 PM, during three consecutive days, using the infrared thermometry technique, under glasshouse environment. It was observed that genotypes canopy temperatures were significantly higher under water deficiency than under well-watered conditions. Nevertheless, Bat-70 had a lower canopy temperature under water deficiency than Bat-66 and G-3776. The possibility of using canopy temperature to detect crop water stress and on primary screenning of drought tolerant bean genotypes was suggested

Caso incomum de filariose linfática mediastinal com estenose da artéria pulmonar

E descrito um caso incomum de filariose linfática, devido a Wuchereria Bancrofti, com localização dos vermes nos linfonodos e linfáticos do mediastino. A intensa reação do conjuntivo mediastinal, provavelmente desencadeada por macrofilárias mortas, determinou no paciente - de 9 anos, residente em Belém, Estado do Pará - estreitamento do tronco e dos ramos principais da artéria pulmonar, defeito tido, inicialmente, como de natureza congênita. O exame histopatológico de duas dentre várias formações nodulares encontradas no mediastino, durante o ato operatório,permitiu, no entanto, estabelecer-se a verdadeira causa da alteração exibida pelo paciente. O achado representa uma formà curiosa de infecção por W. bancrofti, completamente inesperada, quando se considera que a prevalência da bancroftose é, hoje, muito baixa na cidade de Belém. Segundo dados oficiais, o índice de microfilaremia atingiu, em 1985, nessa cidade, cerca de 0,1% apenas, enquanto que, há algumas décadas, era ele estimado em mais de 10%.An unusual case of bancroftian filariasis caused by the presence of macrofilariae in the mediastinal lymphatic vessels is presented. The considerable tissue reaction developed in the mediastinum, probably in relation to products released by dead worms, provoked a severe constriction of the trunk and main branches ofthe pulmonary artery, which conducted to a initial diagnosis of congenital heart disease. The patient, a 9-year-old boy living in Belém-Pará, was admitted to the Belém Hospital and operated at the heart unit, on March 1983. Several fibrous masses were found in the anterior mediastinum, some of them being close to the bifurcation of the pulmonary trunk. The artery presented a severe constriction and a thickened wall. Two of the fibrous nodules were removed for histopathological examination and the sections showed that the masses consisted of lymph nodes surrounded by fibrous tissue and dilated lymphatic vessels. Lying inside the vessels there were numerous sections of filarial worms, recognized as mature females of Wuchereria bancrofti. Some of the worms had died and become calcified. Blood films obtained from the patient after the operation were negative for microfilariae. However, a member of his family, a 14-year-old sister, had been given a course of diethylcarbamazine (DEC), in January of the same year, because, in a routine examination, microfilariae of Wuchereria bancrofti had been demonstrated in her peripheral blood

Mitochondrial bioenergetics deregulation caused by long-chain 3-hydroxy fatty acids accumulating in LCHAD and MTP deficiencies in rat brain: A possible role of mPTP opening as a pathomechanism in these disorders?

AbstractLong-chain 3-hydroxylated fatty acids (LCHFA) accumulate in long-chain 3-hydroxy-acyl-CoA dehydrogenase (LCHAD) and mitochondrial trifunctional protein (MTP) deficiencies. Affected patients usually present severe neonatal symptoms involving cardiac and hepatic functions, although long-term neurological abnormalities are also commonly observed. Since the underlying mechanisms of brain damage are practically unknown and have not been properly investigated, we studied the effects of LCHFA on important parameters of mitochondrial homeostasis in isolated mitochondria from cerebral cortex of developing rats. 3-Hydroxytetradecanoic acid (3 HTA) reduced mitochondrial membrane potential, NAD(P)H levels, Ca2+ retention capacity and ATP content, besides inducing swelling, cytochrome c release and H2O2 production in Ca2+-loaded mitochondrial preparations. We also found that cyclosporine A plus ADP, as well as ruthenium red, a Ca2+ uptake blocker, prevented these effects, suggesting the involvement of the mitochondrial permeability transition pore (mPTP) and an important role for Ca2+, respectively. 3-Hydroxydodecanoic and 3-hydroxypalmitic acids, that also accumulate in LCHAD and MTP deficiencies, similarly induced mitochondrial swelling and decreased ATP content, but to a variable degree pending on the size of their carbon chain. It is proposed that mPTP opening induced by LCHFA disrupts brain bioenergetics and may contribute at least partly to explain the neurologic dysfunction observed in patients affected by LCHAD and MTP deficiencies

FORMACIÓN EN NANOTECNOLOGÍA PARA LA EDUCACIÓN SECUNDARIA: ACCIONES Y PERSPECTIVAS DEL PROYECTO LIFENANO-IFSP

En el medio de los desafíos e iniciativas encaminadas para mejorar la enseñanza en diversas áreas del conocimiento en la educación básica, está el perfeccionamiento de la formación docente. Esto viene siendo debatido tanto por el gobierno federal brasileño como por la comunidad académica. Los enfoques metodológicos innovadores orientados a temas de ciencia contemporáneos y las propuestas para la introducción sistemática de conceptos de nanociencia y nanotecnología son aún muy incipientes. Esa situación no se limita a Brasil; se presenta también en otros países iberoamericanos. En este panorama es necesario el uso de estrategias colaborativas con el fin de establecer acciones de difusión y formación en nano-ciencia y nanotecnología. En este trabajo se presentan acciones y perspectivas de un laboratorio para capacitación inter-disciplinar de educadores en nanociencia y nanotecnología en el interior del estado de São Paulo, en Brasil. También se muestra como el laboratorio interactúa con un programa de becas de iniciación a la enseñanza financiado por el gobierno federal brasileño. Finalmente, se discuten las motivaciones de los estudiantes participantes y las potenciales contribuciones del laboratorio para una red internacional orientada a la difusión y a la capacitación en nanociencia y nanotecnología.Among the challenges and initiatives aiming the improvement of teaching in several areas of knowledge in basic education, the enhancement of the formation of teachers plays a key role. Both the Brazilian government and the academic community have debated about this. Innovative methodological approaches devoted to contemporary topics of science are still incipient. This occurs in Brazil as well as in other Iberian American countries. In these conditions, the use of collaborative strategies is necessary towards the diffusion and the education in nanoscience and nanotechnology. This work presents actions and perspectives of the laboratory for the interdisciplinary formation of teachers in nanoscience and nanotechnology in the countryside of the State of São Paulo, in Brazil. It has been shown how this laboratory interacts with an institutional program of fellowships for teaching apprenticeship that is supported by the Brazilian Federal Government. Finally, the motivations of the participating students and the contributions of the laboratory to an international network devoted to the diffusion and education in nanoscience and nanotechnology are discussed

Benefícios da suspensão de células vegetais para os fungos micorrízicos vesículo-arbusculares in vitro. II Efeitos da concentração e da viabilidade das células

The effects of addition of 0, 500, 1,000, 1,500, 3,000 and 6,000 of pueraria cell suspension per 20 ml of medium and cell viability on spore germination and germ tube growth of vesicular arbuscular mycorrhizal fungi were studied in agar and liquid media. Additions of 500 viable pueraria cells gave the greatest benefits to either germination or mycelial growth. On the other hand, addition of dead cells had no significant effects on the spores. This result indicates that the beneficial effects of plant cell suspension depend upon their metabolic activity. It was also found that the presence of viable plant cells did not stimulate independent growth of hyphae after detachment of the parent spore.Estudaram-se os efeitos da adição de 0,500, 1.000, 1.500, 3.000 e 6.000 células vegetais de puerária por 20 ml de meio e da viabilidade das mesmas sobre a germinação e crescimento micelial dos fungos micorrízicos vesículo-arbusculares em meio ágar-água e líquido. Os maiores benefícios, tanto para a germinação, quanto para crescimento micelial, foram obtidos com a adição de 500 células viáveis de puerária. A adição, ao meio, de células mortas não exerceu efeito significativo sobre os esporos, do que se infere que os benefícios das células vegetais sobre a germinação e crescimento micelial dependem da sua atividade metabólica. A presença de células viáveis não estimulou o crescimento independente do micélio destacado dos esporos

Beneficios da suspensão de células vegetais para os fungos micorrízicos vesículo-arbusculares in vitro. III Efeitos de diferentes meios de cultivo.

The effects of different culture medium of plant cells (B5, LS, MS, 5H and White) were evaluated in the presence or absence of Pueraria Pueraria phaseoloides (Roxb.) Benth cells upon germination and growth of mycelium of Scutellospora heterogama. Nondiluted MS medium extended the viability period of cells and at ten times (0,1X MS) dilution and addition of cells from Pueraria hypocotyls promoted the greatest benefit to germination and ramification of the mycelium of Gigaspora gigantea, Gigaspora margarita and Scutellospora heterogama. Despite the significant mycelium growth, colonization or sporulation by the VAM fungi in the culture medium containing plant cells were not observed.Avaliaram-se os efeitos de diferentes meios de cultivo de células vegetais (B5, LS, MS, SH, White) na presença e ausência de células de puerária Pueraria phaseoloides (Roxb) Benth sobre a germinação e crescimento micelial de Scutellospora heterogama. O meio MS não diluído prolongou o período de viabilidade das células, e quando diluído dez vezes (0,1 x MS), e com adição de células obtidas de hipocótilo de puerária promoveu os maiores benefícios para a germinação e ramificação do micélio de Gigaspora gigantea, Gigaspora margarita e Scutellospora hetero gama. Apesar do crescimento micelial abundante, em nenhum meio de cultivo com adição de células foram verificados sinais visuais de colonização das células ou esporulação dos fungos micorrízicos VA

HOLOGRAFÍA Y REALIDAD VIRTUAL EN LA ENSEÑANZA DE NANOTECNOLOGÍA: NUEVOS HORIZONTES DIRIGIDO A EDUCACIÓN SECUNDARIA

El uso casi inseparable de los recursos tecnológicos en las dimensiones sociales, profesionales y afectivas, sugieren un nuevo proceso de resignificación sociocultural y cognitiva. Tales desarrollos ganan notoriedad con el advenimiento de las nuevas tecnologías de la información y de la comunicación (NTIC), trayendo nuevos horizontes para las prácticas educativas. Las NTIC en el futuro se basará en tecnologías emergentes, que en propuestas educativas permitirán integrar y articular saberes de diferentes áreas del conocimiento de una manera interdisciplinar. Estas tecnologías disruptivas tienden a proporcionar avances significativos en áreas, tales como: tecnología de la información, la holografía, nanotecnología, biotecnología, ciencias cognitivas, robótica e inteligencia artificial. Entre esta gama de posibilidades, incluye tecnologías capaces de expresar representaciones de la realidad o la imaginación, a veces de difícil abstracción. En este contexto, la holografía y la realidad virtual congregan supuestos metodológicos que actúan de forma activa y que motivan, con alto poder de ilustración y de la interactividad. Este trabajo presenta los resultados sobre el uso de la holografía y realidad virtual para la enseñanza de conceptos de nanociencia y nanotecnología (N and N) en la educación secundaria. Metodológicamente este trabajo fue desarrollado con lo uso de estas tecnologías para la enseñanza de N and N en eventos científicos en el período entre 2015 y 2017. Los resultados muestran que los elementos interactivos de estas tecnologías pueden potenciar y corroborar para el aprendizaje significativo de conceptos relacionados con N and N y que son difíciles para la abstracción de los estudiantes.Use almost inseparable from the technological resources in social, professional and emotional dimensions, suggest a new process of sociocultural and cognitive resignification. Such developments gain notoriety with the advent of new technologies of information and communication (NTIC), bringing new horizons for educational practices. ICTs in the future will be based on emerging technologies that will integrate and articulate knowledge from different areas of knowledge in an interdisciplinary manner in educational proposals. These disruptive technologies tend to provide significant advances in areas such as: technology information, holography, nanotechnology, biotechnology, cognitive science, robotics and artificial intelligence. Among this range of possibilities, including technologies capable of express representations of reality or imagination, sometimes difficult to abstraction. In this context, holography and virtual reality meet methodological assumptions that act in an active way and that motivate, with high power of illustration and interactivity. This paper presents the findings on the use of holography and virtual reality for the teaching of concepts in nanoscience and nanotechnology (N and N) in secondary education. Methodologically, this work was developed with use of these technologies for the teaching of N and N in scientific events in the period between 2015 and 2017. The results show that the interactive elements of these technologies can enhance and corroborate to the meaningful learning of concepts related to N and N, and which are difficult for the abstraction of the students

EL JUEGO CAZA-NANO Y LA ENSEÑANZA DE NANO CONCEPTOS: ACTIVIDADES LÚDICAS EN LA EDUCACIÓN SECUNDARIA

Los temas de nanociencia y nanotecnología (N and N) están muy presentes en los medios de comunicación y en la vida cotidiana de la sociedad. Sin embargo, su enseñanza sigue planteando grandes desafíos. En Brasil, las propuestas educativas que tocan conceptos de N and N en el contexto de la educación secundaria son todavía muy incipientes, aunque éstos estén presentes en la vida de los estudiantes. Esta situación se puede atribuir a varios factores, pero principalmente al hecho de que los cursos de formación del profesorado no incluyen sistemáticamente las bases metodológicas necesarias para la enseñanza de esos temas actuales y relevantes de la ciencia. La articulación de estos contenidos con enfoques innovadores y motivadores es esencial para mejorar la educación secundaria. Presentamos una propuesta educativa de temas de N and N a través de una actividad lúdica: el juego llamado Caza-Nano. Este está diseñado para mejorar el uso de la notación científica y la comprensión del orden de magnitud, así como el aprendizaje cuestiones relacionadas con la ciencia contemporánea. En este sentido, la investigación reveló que, cuando son bien preparadas, las actividades lúdicas se pueden utilizar en diferentes niveles de enseñanza. Por lo tanto, la investigación pone de relieve aspectos importantes y el potencial de las actividades recreativas como herramientas para la enseñanza y aprendizaje de calidad.The topics of nanoscience and nanotechnology (N and N) are present in the media and in the everyday life of society. However, their teaching continues to pose major challenges. In Brazil, the educational proposals that deal with concepts of N and N in the context of basic education are still incipient, although they are present in students’ lives. This situation may be attributed to several factors, but mainly to the fact that teacher-training courses do not systematically include the necessary methodological basis for teaching such current and relevant topics of science. The articulation of this content with innovative and motivating approaches is essential to improve learning at the High School. We present an educational proposal of N and N-related themes, through a playful activity: the game called as Caza-Nano. This has been designed to improve the use of scientific notation and understanding of the order of magnitude and the learning of topics of contemporary science. In this regard, the investigation revealed that, when appropriately prepared, playful activities may be used at different levels of education. Therefore, the research highlights important aspects and the potential of recreational activities as tools for the quality of teaching and learning in science
