The compositional techniques of Luigi Dallapiccola\u27s twelve-tone music
No full textThe twelve tone music of Luigi Dallapiccola is generally summarized, concentrating on the solo piano work, Quaderno musicale di Annalibera as an example. Movement I, III, XI of the piece are analyzed in more detail, highlighting the serial techniques involved. The author\u27s own composition and compositional process is then described with reference to the compositional techniques of Luigi Dallapiccola. The three movements and author\u27s composition are included as musical scores
The influence of Luigi Dallapiccola on Bruno Maderna's early serialism
No full textThis thesis examines the influence of Luigi Dallapiccola (1904–1975) on Bruno Maderna's (1920–1973) early serialism by means of a comparative analysis. Two song cycles are compared: Dallapiccola's Liriche greche (1942–45) and Maderna's Tre liriche greche per piccolo coro, soprano solo e strumenti (1948). The author presents separate analyses of each work (Chapters 1 and 2), which form the basis for comparison (Chapter 3). The analysis of Dallapiccola's Liriche greche examines in particular the effects of his non-serial compositional choices on his twelve-tone method. The discussion of Maderna's Tre liriche greche illustrates how his novel methods of serial development result from his aesthetic concern to create diversified musical surfaces. The comparison of the two composers' compositional methods establishes a number of similarities that substantiate Dallapiccola's influence on Maderna. The thesis concludes with a brief investigation of the relationship between Maderna's early and mature serialism.Le présent mémoire examine l'influence de Luigi Dallapiccola (1904–1975) sur les premières œuvres sérielles de Bruno Maderna (1920–1973) au moyen d'une analyse comparative. Deux cycles de chansons y sont comparés : les Liriche greche de Dallapiccola (1942–1945) et les Tre liriche greche per piccolo coro, soprano solo e strumenti (1948) de Maderna. L'auteur présente des analyses de chaque œuvre aux chapitres 1 et 2, sur lesquelles il fonde son analyse comparative présentée au chapitre 3. L'analyse des Liriche greche de Dallapiccolla examine plus particulièrement les effets de ses choix compositionnels non sériels sur sa méthode dodécaphonique. La discussion des Tre liriche greche de Maderna illustre comment les méthodes innovatrices de développement sériel du compositeur résultent de sa préoccupation esthétique de créer des surfaces musicales diversifiées. La comparaison des approches des deux compositeurs établit plusieurs similitudes qui confirment l'influence de Dallapiccola sur Maderna. Le mémoire se termine par un bref examen des relations entre le sérialisme primitif et tardif de Maderna
Familial mandibuloacral dysplasia: report of an additional Italian patient
No full textMandibuloacral dysplasia is a rare condition. Only 11 families have been reported and five of them were Italian, while consanguinity was found only in one report. We describe an additional Italian patient born from consanguineous parents. (C) 2000 Wiley-Liss, Inc
As obras para piano de Luigi Dallapiccola
No full textLuigi Dallapiccola, ao qual se associa um período pertinente na história europeia, marca também o início de uma nova etapa na história da música italiana.
Este Projecto pretende abordar as obras para piano solo deste compositor, efectuando a sua análise, bem como o enquadramento histórico, social e cultural no qual se inclui. Esta é uma forma de entender as suas escolhas e o resultado final sonoro das referidas peças, construído através de técnicas composicionais em voga na época, como por exemplo o dodecafonismo.
Tentar-se-á responder a questões de estilo, influências e abordagens composicionais.Luigi Dallapiccola, to whom we associate a relevant period in the european history, also settles the beginning of a new stage in the history of italian music.
This Project aims to approach the piano works of this composer, analysing them, as well as contextualize the historical, social and cultural background in which he lived. This is a way of understanding his choices and the sonorous outcome of the works, developped through compositional techniques of the time, like the twelve-tone system.
The author will try to answer questions regarding the compositional style, influences and approaches
Mutations of the Nogo-66 receptor (RTN4R) gene in schizophrenia
No full textSchizophrenia (SCZD) or schizoaffective disorders are quite common features in patients with DiGeorge/velo-cardio-facial syndrome (DGS/VCFS) as a result of chromosome 22q11.2 aploinsufficiency. We evaluated the Nogo-66 receptor gene (RTN4R), which maps within the DGS/VCFS critical region, as a potential candidate for schizophrenia susceptibility. RTN4R encodes for a functional cell surface receptor, a glycosylphosphatidylinositol (GPI)-linked protein, with multiple leucine-rich repeats (LRR), which is implicated in axonal growth inhibition. One hundred and twenty unrelated Italian schizophrenic patients were screened for mutations in the RTN4R gene using denaturing high performance liquid chromatography (DHPLC). Three mutant alleles were detected, including two missense changes (c.355C>T; R119W and c.587G>A; R196H), and one synonymous codon variant (c.54G>A; L18L). The two schizophrenic patients with the missense changes were strongly resistant to the neuroleptic treatment at any dosage. Both missense changes were absent in 300 control subjects. Molecular modeling revealed that both changes lead to putative structural alterations of the native protein
Protocol for prenatal diagnosis of cystic fibrosis based on studies of alkaline phosphatase isoenzymes
No full textProtocol for prenatal diagnosis of cystic fibrosis based on studies of alkaline phosphatase isoenzymes
No full text: Amniotic fluid analysis of microvillar enzymes, including alkaline phosphatase (ALP) total activity and ALP isoenzymes, has been widely experimented with and used for the prenatal diagnosis of cystic fibrosis in the second trimester of gestation. Since the development of cystic fibrosis molecular analysis, interest in these biochemical tests has been maintained for those instances in which the pregnancy is not fully informative by restriction fragment length polymorphism analysis or DNA is not available from the index-affected child. However, recommended biochemical protocols do not provide clear-cut diagnostic results in a minority of cases. We have tested the reliability of cystic fibrosis biochemical prediction by ALP high-resolution electrophoresis and ALP kinetic studies after inactivation by urea. With this approach, all the amniotic fluid samples that had not been unambiguously classified as affected or unaffected by standard microvillar enzymes analysis were definitely categorized. The proposed method seems to improve the diagnostic accuracy in pregnancies with a one in four risk of resulting in a child with cystic fibrosis
