Intraventricular pressure gradients in heart failure
Guerra, Miguel; Silva, Carmen Brás; Amorim, Mário; Bento, Cláudia; Bastos, Pedro; Moreira, AdelinoThe aim of the present study was to characterize intraventricular pressure gradients (IVPGs) in an animal model of chronic heart failure. New Zealand rabbits were treated with doxorubicin (heart failure group, n=5) or saline (control group, n=5) and instrumented with pressure catheters placed in the apex and outflow-tract of left ventricle (LV) and with sonomicrometer crystals placed in the apex and base of the...
Left intraventricular diastolic and systolic pressure gradients
Guerra, Miguel; Sampaio, Francisco; Brás-Silva, Carmen; Leite-Moreira, AdelinoTo describe left ventricular (LV) function comprehensively, it is crucial to characterize precisely transmitral, intraventricular and transaortic pressure-flow relations. The site of measurement is important; as the measurement location is moved from the mitral valve toward the apex and the outflow tract, important regional pressure differences are recorded inside the LV. These intraventricular pressure gradien...
Identificação molecular da uva 'Goethe' de Urussanga - SC por marcadores micros...
Schuck,Mariane Ruzza; Moreira,Flavia Maia; Voltolini,José Afonso; Guerra,Miguel Pedro; Grando,Maria Stella; Silva,Aparecido Lima daA variedade Goethe é símbolo da vitivinicultura da região de Urussanga, sul do Estado de Santa Catarina, a qual, atualmente, busca a Indicação Geográfica da Uva e do Vinho Goethe. Para isto, um dos requisitos necessários é a identificação precisa do material genético. Os marcadores microssatélites constituem a ferramenta molecular mais utilizada para a identificação varietal de videira em todo o mundo e têm a c...
Patterns of protein and carbohydrate accumulation during somatic embryogenesis ...
Cangahuala-Inocente,Gabriela Claudia; Steiner,Neusa; Maldonado,Sara Beatriz; Guerra,Miguel PedroThe aim of this work was to quantify the protein, starch and total sugars levels during histodifferentiation and development of somatic embryos of Acca sellowiana Berg. For histological observations, the samples were dehydrated in a battery of ethanol, embedded in historesin and stained with toluidine blue (morphology), coomassie blue (protein bodies) and periodic acid-Schiff (starch). Proteins were extracted u...
Molecular characterization of grapevine from Santa Catarina, Brazil, using micr...
Schuck,Mariane Ruzza; Moreira,Flavia Maia; Guerra,Miguel Pedro; Voltolini,José Afonso; Grando,Maria Stella; Silva,Aparecido Lima daThe objective of this work was to characterize the grape germplasm in Santa Catarina, Brazil, using microsatellite DNA markers (simple sequence repeats - SSR). The DNA samples were collected from leaves and shoots of accessions of public and private collections from the counties Urussanga, Nova Trento, Rodeio, São Joaquim, Campos Novos, Videira, and Água Doce. Ten SSR loci (VVS2, VVMD5, VVMD7, VVMD27, VrZAG62, ...
Adventitious shoots from nodule cluster cultures of Vriesea reitzii: an endemic...
Rech Filho,Arlindo; Vesco,Lírio Luiz Dal; Guerra,Miguel PedroThe Atlantic Forest is a biome with megadiversity and a number of bromeliads take part of it. This is the case of Vriesea reitzii, an endemic bromeliad threatened with extinction. Tissue culture techniques are valuable tools for the mass propagation of bromeliads, thus reducing pressure in the natural habitat. The aim of the present work was to establish an in vitro protocol based on the induction and prolifera...
Microshoots encapsulation and plant conversion of Musa sp. cv. 'Grand Naine
Sandoval-Yugar,Edgar Wilfredo; Dal Vesco,Lírio Luiz; Steinmacher,Douglas André; Stolf,Elaine Cristina; Guerra,Miguel PedroSynthetic seed technologies are useful tools for the field delivery of in vitro derived plantlets. In the present study, different encapsulation procedures and their efficacy in the plantlet regeneration using microshoots of banana cv. 'Grand Naine' were evaluated. Two encapsulation systems were evaluated: i) single encapsulation in beads or droplet hardening method; and ii) double layer or hollow beads. The us...
Estudo anatômico do crescimento do fruto em Acca sellowiana Berg.
Esemann-Quadros,Karin; Mota,Ana Paula; Kerbauy,Gilberto Barbante; Guerra,Miguel Pedro; Ducroquet,Jean Pierre Henri Joseph; Pescador,RoseteA Acca sellowiana Berg. (Myrtaceae) é uma frutífera nativa dos planaltos meridionais do Sul do Brasil e que se encontra em processo de domesticação. Seus frutos são doce-acidulados e podem ser consumidos in natura ou empregados para a produção de sucos e doces. Assim, informações sobre o desenvolvimento, morfologia e anatomia de seus frutos são de grande interesse e foram objetos do presente trabalho. O fruto (...
Reproductive biology in monoecious and gynoecious cucumber cultivars as a resul...
Diola,Valdir; Orth,Afonso I; Guerra,Miguel PThe understanding of both the reproductive biology and the regulation of the sexual expression of cucumber flowers (Cucumis sativus) makes crop management easier and can improve fruit yield and quality. The objective of this study was to evaluate the physiological answer of cucumber floral verticils to the application of IBA. The experiment was carried out in a greenhouse, in completely randomized blocks, with ...
Evidência da atuação do sistema de auto-incompatibilidade tardia em Acca Sellow...
Santos,Karine Louise dos; Lenzi,Maurício; Caprestano,Clarissa Alves; Dantas,Adriana Cibele de Mesquita; Ducroquet,Jean Pierre Henri JosephAcca sellowiana (Myrtaceae) é uma frutífera nativa da região Sul do Brasil e nordeste do Uruguai, que vem despertando grande interesse devido ao alto potencial organoléptico de seus frutos. Neste trabalho, teve-se como objetivo a caracterização do tipo de sistema de incompatibilidade atuante em A. sellowiana, através da avaliação do desenvolvimento dos tubos polínicos. Utilizaram-se dois acessos: 458, sendo aut...
