A.)[ 1 ] Univ Talca, Inst Biol Vegetal & Biotecnol, Lab Fisiol Vegetal & Genet Mol, Talca, ChileChilean strawberry (Fragaria chiloensis) is a berry fruit with excellent organoleptic properties, however its fast softening limits its commercialization. Fruit softening is related to cell wall degradation and several related enzymes have been studied in strawberries, including xyloglucan endotransglycosylase/hydrolase (XTH). Two XTH genes have been identified in F. chiloensis, FcXTH1 and FcXTH2. FcXTH1 transcripts increased during fruit growth and softening, while FcXTH2 transcripts were high in vegetative tissues. XTH gene expression seems to be regulated in plants by different factors including hormones. To test their responsiveness, fruit were treated with auxin, abscisic acid, gibberellins and ethylene, and the expression of FcXTH isoforms was analysed. qPCR analysis revealed a significant variation in the expression of FcXTH genes after hormone treatments, showing an activator effect of auxins and GA(3) on both FcXTH genes, an inhibitory effect of ethylene on FcXTH2, and an inductive effect of ABA on FcXTH1 gene expression. FcXTH1 and FcXTH2 gene promoters were cloned and in silico analysed to reveal putative cis elements. Different regulatory elements responding to hormones were found in each promoter sequence. The changes in expression in response to hormone treatments are consistent with the regulatory elements described in the promoter sequences of FcXTH genes. (C) 2012 Elsevier B.V. All rights reserved
From textbook to patient: a practical guide to train the end-to-side microvascular anastomosis
No full textMicrovascular anastomosis is one of the most challenging neurosurgical techniques. Mastering this technique allows to perform intracranial bypass with arteries of small caliber usually placed in deep narrow surgical fields. The aim of this paper is to describe step by step end-to-side microanastomosis training method by using polyvinyl alcohol (PVA) hydrogel tubing as it is easily reproducible. The tubing comes in sizes from 0.3 mm to 5 mm and has a texture and consistency similar to real vessels. This is based on the Teishinkai Hospital anastomosis technique. Continuous practice in microvascular anastomosis is of great importance in training vascular neurosurgeon. The PVA hydrogel tubing described in this article are useful and cost-effective material in the training of microvascular anastomosis. This practical guide model is easy to set up for repeated practice, and will contribute to facilitate ‘off-the-job’ training by young neurosurgeons and the development and maintenance of microsurgical skills in both resident neurosurgeons and experts who wish to master the various levels of anastomosis technique. There is no shortcut to master this technique, only hard work and perseverance

Preinvex Functions And Weak Efficient Solutions For Some Vectorial Optimization Problem In Banach Spaces
No full textIn this work, we introduce the notion of preinvex function for functions between Banach spaces. By using these functions, we obtain necessary and sufficient conditions of optimality for vectorial problems with restrictions of inequalities. Moreover, we will show that this class of problems has the property that each local optimal solution is in fact global. © 2004 Elsevier Ltd.

No full textA questão que originou esta pesquisa surgiu da clínica, campo de investigação e reduto de trabalho do psicanalista. Ao observar a mudança de constelações psíquicas que vêm se apresentando no consultório, e constatar os limites que a técnica clássica impõe à escuta psicanalítica, fez-se necessário conhecer outras teorias e técnicas que possibilitassem a ampliação da sensibilidade clínica, buscando, via contratransferência, uma forma de escutar os conteúdos psíquicos de pacientes com falha no processo de simbolização. O trabalho de investigação visou então desenvolver e sustentar a tese de que a perlaboração da contratransferência pode ser um importante recurso que coloca à disposição do trabalho analítico o material necessário para realizar construções em análise de representações-coisa. Os argumentos são construídos em três etapas: aproximação dos conceitos de contratransferência e de perlaboração, sustentando a primeira proposição da tese de perlaboração da contratransferência; apresentação dos aportes teóricos relativos ao conceito de contratransferência, desenvolvidos por autores pós-freudianos, e descrição do trabalho psicanalítico, lançando luz na metapsicologia do analista, composta, precisamente, dos processos psíquicos envolvidos na perlaboração da contratransferência, quais sejam, empatia, identificação projetiva em sua forma comunicativa e rêverie. Entendemos que esses três conceitos operando juntos permitem sustentar a dimensão estética da contratransferência, que, via trabalho do analista, disponibiliza material para realizar a figurabilidade necessária às simbolizações primárias. Trata-se do último passo da tese, que é sustentar a proposição dequea perlaboração da contratransferência é uma etapa sinequa non das construções em análise. O modelo de trabalho que propomos como paradigma deste modo de psicanalisar é o da Gradiva, que encontra na sua própria alucinação a forma de rememoração e perlaboração das cadeias representacionais interrompidas no psiquismo de Hanold. Os argumentos foram desenvolvidos a partir dos seguintes historiais clínicos de autores consagrados na psicanálise: o Homem dos Lobos, a análise de Margareth Little com Winnicott, o caso de análise mútua de Elizabeth Severn e por fim, o caso Didier da psicanalista Julia Kristeva. O percurso nos levou a contribuir com o campo científico a partir de três pontos: compreender como o psicanalista realiza este trabalho; alçar a contratransferência a uma dimensão estética, que visa dar forma e sentido quando há falhas nesses aspectos no analisando, e, sobretudo, recuperar o conceito de alucinação como processo de rememoração, sendo esta compreendida como a matriz da criação simbólicaThe question that originated this research arose from the clinic, field of investigation and heartland of work of the psychoanalyst. When observing the change in psychic constellations that are appearing in the practice, and verifying the limits that the classical technique imposes to the psychoanalytical´s listening, it became necessary to know other theories and techniques that would allow the amplification of the clinical sensitivity, seeking, via countertransference, a way of listening to the psychic contents of patients with failure in the process of symbolization.The research work aimed at developing and sustaining the thesis that the perlaboration of the countertransference can be an important resource that makes available to the analytical work the material necessary to perform constructions in analysis of thing representations. The arguments are constructed in three stages: approximation of the concepts of countertransference and perlaboration, underpinning the first proposition of the thesis of perlaboration of countertransference; presentation of the theoretical contributions on the concept of countertransference, developed by post-Freudian authors, and description of psychoanalytic work, throwing light on the analyst\'s metapsychology, precisely composed by the psychic processes involved in the perlaboration of countertransference, namely, empathy, projective identification in its communicative and rêverie forms.We understand that these three concepts working together allow us to underpin the aesthetic dimension of countertransference, which, through the work of the analyst, provides material to achieve the necessary figurability of primary symbolizations. This is the last step of the thesis, which is to underpin the proposition that the perlaboration of the countertransference is a sine qua non stage of the constructions in the analysis. The work model that we propose as a paradigm for this way of psychoanalysis is Gradiva\'s, who finds in its own hallucination the form of recalling and perlaboration of the representational chains interrupted in the psychism of Hanold. The arguments were developed from the following clinical histories of well-known authors in psychoanalysis: the Man of the Wolves, the analysis of Margareth Little with Winnicott, the case of mutual analysis of Elizabeth Severn and, finally, Didier case of the psychoanalyst Julia Kristeva.The course led us to contribute with the scientific field since three points: to comprehend how the psychoanalyst achieves this work; to elevate countertransference to an aesthetic dimension, which aims to give form and meaning when there are flaws in these aspects in the analysand, and, above all, to recover the concept of hallucination as a process of recalling, which is understood as the matrix of symbolic creatio
