Characterization of Apoptosis-Related Oxidoreductases from Neurospora crassa
Patrícia Carneiro, Margarida Duarte, Arnaldo Videira
PLOS ONE , 2012, DOI: 10.1371/journal.pone.0034270
Abstract: The genome from Neurospora crassa presented three open reading frames homologous to the genes coding for human AIF and AMID proteins, which are flavoproteins with oxidoreductase activities implicated in caspase-independent apoptosis. To investigate the role of these proteins, namely within the mitochondrial respiratory chain, we studied their cellular localization and characterized the respective null mutant strains. Efficiency of the respiratory chain was analyzed by oxygen consumption studies and supramolecular organization of the OXPHOS system was assessed through BN-PAGE analysis in the respective null mutant strains. The results demonstrate that, unlike in mammalian systems, disruption of AIF in Neurospora does not affect either complex I assembly or function. Furthermore, the mitochondrial respiratory chain complexes of the mutant strains display a similar supramolecular organization to that observed in the wild type strain. Further characterization revealed that N. crassa AIF appears localized to both the mitochondria and the cytoplasm, whereas AMID was found exclusively in the cytoplasm. AMID2 was detected in both mitochondria and cytoplasm of the amid mutant strain, but was barely discernible in wild type extracts, suggesting overlapping functions for the two proteins.

Abstract: Relatamos o caso de um doente de 63 anos com hemorragia originária no intestino delgado. Dada a presen a de insta-bilidade hemodinamica, que obrigou à suspens o da enteroscopia com duplo bal o, foi submetido a enteroscopia intra-operatória com abordagem por via oral. As les es encontradas incluem três angiodisplasias, tratadas com árgon-plasma, e duas úlceras, que foram ressecadas. A enteroscopia intra-operatória poderá ser uma op o terapêutica em pacientes com sangramento com origem no intestino delgado, designadamente quando evidenciem instabilidade hemodinamica We report the case of a 63-year-old with small intestinal bleeding. Due to the fact that he was hemodynami-cally unstable, double-balloon enteroscopy had to be suspended. Urgent laparotomy with intraoperative enteroscopy by an orally passed endoscope was done. Three angiodysplasic lesions were treated with argon-plasma coagulation and two bleeding ulcers were accurately identified and resected. Intraoperative enteroscopy may be a therapeutic option, namely in unstable patients with small intestinal bleeding

Abstract: the effect of ms medium, nitrogen and sucrose war investigated on "in vitro" propagation of shoot nodal explants of chrysanthemum (dendranthema grandiflora tzvelev.) cultivars orange reagen. ms medium was tested using the following concentrations: 0, 25, 50, 75, 100, 125 and 150% in combination with sucrose doses of: 0, 0.75, 1.5, 3.0, 6.0 and 12.0%. nitrogen was tested using the concentrations of 0, 25, 50, 75, 100, 125 and 150% in combination with the sucrose doses used as above. best shoot development was observed when nodal segments were cultivated on medium containing concentrations between 50 and 150% of ms in combination with 6% sucrose. no satisfactory shoot length was observed when 50% ms was used. roots were not observed at concentrations above 100% of ms and nitrogen. in order to obtain successful "in vitro" propagation of chrysanthemum, our results suggest the use of 75% ms, with 75% of nitrogen and 6% of sucrose.

Abstract: floriculture is characterized by the cultivation of ornamental and cut plants (flowers and foliages), potted plants, whether flowering or not, and even the production of seeds, bulbs, palm trees, seedlings of trees, shrubs and other species for cultivation in gardens. so, with the aim at accomplishing a study of seedling production for garden in the state of minas gerais, a questionnaire was applied to the growers of the state of minas gerais, over the period of 2003 to 2005. the visits were paid in loco and the producers were identified by means of visits to the growing areas and the questionnaires were answered by them. by analyzing the answers contained in the questionnaires, it was identified that the production of garden seedlings in the state of minas gerais is a business carried out by 563 producers in a planted area of about 832.2425 ha.

Abstract: cut flowers are important products of brazilian floriculture. the characteristics of minas gerais production are, nevertheless, unknown. so, with the purpose of performing a study of the cut flower production in the state of minas gerais, a questionnaire was applied to flower growers of minas gerais state, in the period of 2003 to 2005. the visits were paid in loco and the growers were identified by means of visits to the flower-growing areas and the questionnaires were answered by them. by analyzing the answers contained in the questionnaires, it was identified that the cut flower production in the state of minas gerais is a business accomplished by 188 growers in a planted area of about 290.6836 ha. the main species grown in the state are: rose (151.5710 ha), sempre-vivas (57.26 ha), cala lilly flowers (16.0255 ha), carnation (12.6290 ha) and heliconia (11.7600 ha). the production is sold all over brazil and it is also exported to countries of europe, asia and north america. the main exported produces are: cut roses, cut orchids and sempre-vivas.

Psicologia , 2005,
Abstract: this paper focus on the study of place identity contents, an issue that has been neglected by the literature. the main purpose was to identify the place identity contents and to analyse the relationships between them and the level of identification with the place, as well as with the place dimension. two exploratory studies were conducted. the first was a qualitative study with university students, and the second a correlational one with a sample of residents living nearby oporto. the results pointed out five content dimensions (instrumental, aesthetic, historic-cultural, answer to basic needs and environmental and social problems), that were significantly related to the other variables under investigation. the results were discussed in the light of relevant literature.

Abstract: this work was developed with the objective of evaluating the physiologic quality of corn seeds uenf 506-8 covered and the resistance of the covering using different proportions of cement. it was used in the covering of the seeds a mixture of lime and culture media. as cement was used polivinil acetate glue (pva). the covering of the corn seeds was executed with a mixture of 70% (w/w) of lime, 10% (w/w) of semi-solid culture media jnfb and 20% (w/w) of water. in the mixture different proportions were added: 0,5; 1; 2; 3; 4 and 5% (w/w). evaluating the resistance of the covering was simulated the transport and the manual seeding, and the mechanical seeding of the covered seeds. the evaluation of the physiologic quality of the seeds was accomplished in seeds not covered and covered seeds with the proportions of cement: 0,5; 1; 2; 3; 4 and 5%. the increase of the proportion of cement of 2 for 3% caused a small reduction no significant in the speed of the germination, emergency speed and emergency, but it didn't affect the final number of normal plants in the germination test and cold test. for the manual seeding the use of 2% of cement is recommended and for the mechanical seeding 4% of cement.
