The Space Race di Alex Latimer. Traduzione del romanzo di un autore sudafricano.

In the following thesis I present the book The Space Race from South African author Alex Latimer and my translation of some chapters, from English into Italian. Alex Latimer is an illustrator and author based in Cape Town, known mostly for his picture books for children, although his works also appear in magazines and advertisements. The Space Race is his first novel, but it immediately had a good reception amongst readers and critics. The author, his work and his novel The Space Race will be presented in depth in Chapter 1 of the thesis. Then, an overview on the South African fictional production will follow in Chapter 2, focusing mainly on the contemporary trends and trying to understand if and how The Space Race fits. Before presenting my translation and my reflections on the translating process itself, I will outline in Chapter 3 my general approach to the text and its translation, as well as explain the reasons why I chose those specific parts of the book. The original texts and their translations are presented in Chapter 4, preceded by a short introduction to better understand the position of the chapter in the plot and the elements of interests contained in it. A commentary on the translating process will follow in Chapter 5, about problems or just remarks on aspects of interest; also, further elements of complication in the text are described and my solutions presented. The thesis ends with a conclusion on the work done.

Cardiac remodeling in Drosophila arises from changes in actin gene expression and from a contribution of lymph gland-like cells to the heart musculature

Understanding the basis of normal heart remodeling can provide insight into the plasticity of the cardiac state, and into the potential for treating diseased tissue. In Drosophila, the adult heart arises during metamorphosis from a series of events, that include the remodeling of an existing cardiac tube, the elaboration of new inflow tracts, and the addition of a layer of longitudinal muscle fibers. We have identified genes active in all these three processes, and studied their expression in order to characterize in greater detail normal cardiac remodeling. Using a Transglutaminase-lacZ transgenic line, that is expressed in the inflow tracts of the larval and adult heart, we confirm the existence of five inflow tracts in the adult structure. In addition, expression of the Actin87E actin gene is initiated in the remodeling cardiac tube, but not in the longitudinal fibers, and we have identified an Act87E promoter fragment that recapitulates this switch in expression. We also establish that the longitudinal fibers are multinucleated, characterizing these cells as specialized skeletal muscles. Furthermore, we have defined the origin of the longitudinal fibers, as a subset of lymph gland cells associated with the larval dorsal vessel. These studies underline the myriad contributors to the formation of the adult Drosophila heart, and provide new molecular insights into the development of this complex organ.

The effects of auditory stimulation with music on heart rate variability in healthy women

OBJECTIVES: There are no data in the literature with regard to the acute effects of different styles of music on the geometric indices of heart rate variability. In this study, we evaluated the acute effects of relaxant baroque and excitatory heavy metal music on the geometric indices of heart rate variability in women. METHODS: We conducted this study in 21 healthy women ranging in age from 18 to 35 years. We excluded persons with previous experience with musical instruments and persons who had an affinity for the song styles. We evaluated two groups: Group 1 (n = 21), who were exposed to relaxant classical baroque musical and excitatory heavy metal auditory stimulation; and Group 2 (n = 19), who were exposed to both styles of music and white noise auditory stimulation. Using earphones, the volunteers were exposed to baroque or heavy metal music for five minutes. After the first music exposure to baroque or heavy metal music, they remained at rest for five minutes; subsequently, they were re-exposed to the opposite music (70-80 dB). A different group of women were exposed to the same music styles plus white noise auditory stimulation (90 dB). The sequence of the songs was randomized for each individual. We analyzed the following indices: triangular index, triangular interpolation of RR intervals and Poincaré plot (standard deviation of instantaneous beat-by-beat variability, standard deviation of the long-term RR interval, standard deviation of instantaneous beat-by-beat variability and standard deviation of the long-term RR interval ratio), low frequency, high frequency, low frequency/high frequency ratio, standard deviation of all the normal RR intervals, root-mean square of differences between the adjacent normal RR intervals and the percentage of adjacent RR intervals with a difference of duration greater than 50 ms. Heart rate variability was recorded at rest for 10 minutes. RESULTS: The triangular index and the standard deviation of the long-term RR interval indices were reduced during exposure to both music styles in the first group and tended to decrease in the second group whereas the white noise exposure decreased the high frequency index. We observed no changes regarding the triangular interpolation of RR intervals, standard deviation of instantaneous beat-by-beat variability and standard deviation of instantaneous beat-by-beat variability/standard deviation in the long-term RR interval ratio. CONCLUSION: We suggest that relaxant baroque and excitatory heavy metal music slightly decrease global heart rate variability because of the equivalent sound level.

Da un dialetto all'altro: napoletano e veronese nella traduzione della commedia "Grisù, Giuseppe e Maria" di Gianni Clementi

La tesina si occupa dell’adattamento di una commedia scritta in napoletano, Grisù, Giuseppe e Maria di Gianni Clementi, in dialetto veronese da parte di Daniele Marchesini. Si cercherà di mettere in luce i tratti caratteristici dell’originale e di descrivere e motivare la scelta del dialetto da parte dell’autore (in particolare il ruolo del dialetto rispetto alle altre “lingue” presenti nella commedia e di come queste lingue caratterizzino i personaggi) e di vedere come l’adattamento veronese riproponga, utilizzando un altro dialetto e altri riferimenti culturali, il medesimo rapporto fra dialetto e lingua italiana e in generale le altre lingue presenti nel testo originale.

Novaja drama e Teatr Praktika: uno sguardo al teatro russo contemporaneo. Proposta di traduzione della piéce di Natalija Mošina "Žara"

Questa tesi si pone come scopo quello di studiare la scena teatrale contemporanea russa, utilizzando come pretesto la traduzione della piéce “Žara” dell’autrice Natalija Mošina. Mošina fa parte del movimento teatrale chiamato ‘novaja drama’, che si è sviluppato in Russia a partire da fine anni Novanta. Nel primo capitolo tratteremo brevemente la storia del teatro russo del Novecento, per osservare come si è giunti alla formazione di questo nuovo movimento. Passeremo poi ad analizzare il movimento vero e proprio, concentrandoci sulle posizioni artistiche dei suoi membri e sul tipo di innovazione che vogliono portare al teatro russo. Proporremo poi una selezione dei luoghi che rinnovano la scena teatrale moscovita. Il secondo capitolo è interamente dedicato ad uno di questi luoghi, il Teatr Praktika, primo teatro statale ad occuparsi esclusivamente di testi contemporanei, di cui vedremo la storia dalla sua fondazione ai giorni nostri e analizzeremo il repertorio vedendo come gli spettacoli messi qui in scena riflettano le posizioni del novaja drama. Nel capitolo conclusivo parleremo più approfonditamente della pièce da noi tradotta vedendo come si colloca all’interno della produzione dell’autrice e del novaja drama, analizzandone la messa in scena al Praktika. Proporremo poi delle riflessioni sulla traduzione di testi teatrali facendo riferimento alla traduzione da noi svolta, che proporremo di seguito.

Dimensions of the Ascending Aorta in Conotruncal Heart Defects

Dilatation of the ascending aorta is an important sequel in conotruncal anomalies, such as tetralogy of Fallot (TOF) or d-transposition of the great arteries (TGA). We measured dimensions and their progression at different levels of the ascending aorta in 80 patients. In TOF patients, mean z-score for aortic annulus was 1.65 (range -3.16-6.47), for sinus 1.93 (range -2.28-5.39), for st-junction 4.15 (range 0.0-8.18), and for ascending aorta 3.51 (range -1.23-6.36). Over time, annulus z-scores increased in the univariate analysis [0.07/year, 95 % confidence interval (CI) 0.01-0.14; p = 0.02], and this was unique to male patients (0.08/year, 95 % CI 0.00-0.15; p = 0.05). z-scores of the ascending aorta decreased (-0.1/year, 95 % CI -0.18 to -0.02; p = 0.02), and this was confined to patients without aortic regurgitation (AR; -0.09/year, 95 % CI -0.18 to -0.01; p = 0.04). In TGA, mean z-score for the aortic annulus was 2.13 (range -3.71-8.39), for sinus 1.77 (range -3.04-6.69), for st-junction 1.01 (range -5.44-6.71), and for ascending aorta 0.82 (range -4.91-6.46). In bivariate analysis, annulus z-scores decreased in females (-0.14/year, 95 % CI -0.25 to -0.03; p = 0.01) and in patients without AR (-0.07/year, 95 % CI -0.14-0.0; p = 0.03). z-scores of the ascending aorta increased significantly in males (0.08/year, 95 % CI 0.0 to 0.16; p = 0.05) and in patients with AR (0.12/year, 95 % CI 0.03-0.21; p = 0.01). In conclusion, TOF and TGA z-scores of the ascending aorta differ significantly from those of the normal population. Progression of z-scores over time is influenced by diagnosis, sex, and presence of AR.

A conditional Mdm2 allele shows the importance of Mdm2 in heart development

Over 50% of sporadic tumors in humans have a p53 mutation highlighting its importance as a tumor suppressor. Considering additional mutations in other genes involved in p53 pathways, every tumor probably has mutant p53 or impaired p53-mediated functions. In response to a variety of cellular and genotoxic stresses, p53, mainly through its transcriptional activity, induces pathways involved in apoptosis and growth arrest. In these circumstances and under normal situations, p53 must be tightly regulated. Mdm2 is an important regulator of p53. Mdm2 inhibits p53 function by binding and blocking its transactivation domain. In addition, Mdm2 helps target p53 for degradation through its E3 ligase activity. Mdm2 null mice are embryonic lethal due to apoptosis in the blastocysts. However, a p53 null background rescues this lethality demonstrating the importance of the p53-Mdm2 interaction, particularly during development. The lethality of the Mdm2 null mouse prior to implantation limits the ability to investigate the role of Mdm2 in regulating p53 in a temporal and tissue specific manner. Does p53 need to be regulated in all tissues throughout the life of a mouse? Does Mdm2 always have to regulate it? To address these questions, we created a conditional Mdm2 allele. The conditional allele, Mdm2FM, in the presence of Cre recombinase results in the deletion of exons 5 and 6 of Mdm2 (most of the p53 binding domain) and represents a null allele. ^ The Mdm2FM allele was crossed with a heart muscle specific Cre expressing mouse (α-myosin heavy chain promoter driven Cre) to ask whether Mdm2 acts as a negative regulator of p53 in the heart. The heart is the most prominent organ early in embryogenesis and is shaped by cell death and proliferation. p53 does not appear to be active in the heart in response to some types of stress, so it remained to be determined if it has to be regulated in normal heart development. Loss of Mdm2 in the heart results in heart defects as early as E9.5. Loss of Mdm2 results in stabilized p53 and apoptosis. This apoptosis leads to a thinning of the myocardial wall particularly in the ventricles and abnormal ventricular structure. Eventually the abnormal heart fails resulting in lethality by E13.5. The embryonic lethality is rescued in a p53 null background. Thus, Mdm2 is important in regulating p53 in the development of the heart. ^

Preservation of myocardial β-adrenergic receptor signaling delays the development of heart failure after myocardial infarction

When the heart fails, there is often a constellation of biochemical alterations of the β-adrenergic receptor (βAR) signaling system, leading to the loss of cardiac inotropic reserve. βAR down-regulation and functional uncoupling are mediated through enhanced activity of the βAR kinase (βARK1), the expression of which is increased in ischemic and failing myocardium. These changes are widely viewed as representing an adaptive mechanism, which protects the heart against chronic activation. In this study, we demonstrate, using in vivo intracoronary adenoviral-mediated gene delivery of a peptide inhibitor of βARK1 (βARKct), that the desensitization and down-regulation of βARs seen in the failing heart may actually be maladaptive. In a rabbit model of heart failure induced by myocardial infarction, which recapitulates the biochemical βAR abnormalities seen in human heart failure, delivery of the βARKct transgene at the time of myocardial infarction prevents the rise in βARK1 activity and expression and thereby maintains βAR density and signaling at normal levels. Rather than leading to deleterious effects, cardiac function is improved, and the development of heart failure is delayed. These results appear to challenge the notion that dampening of βAR signaling in the failing heart is protective, and they may lead to novel therapeutic strategies to treat heart disease via inhibition of βARK1 and preservation of myocardial βAR function.

Frühlings Erwachen. Eine Kindertragödie Proposta di traduzione di alcune scene

Questo elaborato si pone l'obiettivo di condurre un'analisi dell'opera teatrale di Frank Wedekind "Frühlings Erwachen. Eine Kindertragödie", oltre che di offrire una proposta di traduzione di alcune scene tratte dal primo atto. Il dramma del 1891 unisce elemento tragico e comico in una critica alla società guglielmina del XIX secolo nella quale adulti e ragazzi si ritrovano a vivere in mondi separati a causa dell'ipocrisia che si cela nel perbenismo borghese. Wedekind, precursore dell'espressionismo quando ancora imperava il naturalismo, rompe il muro di silenzi e bugie che gli adulti hanno eretto per non guardare in faccia alle problematiche della vita e della sessualità che i giovani sono costretti ad affrontare da soli, spesso con conseguenze tragiche.

The role of BNP testing in heart failure

Brain natriuretic peptide (BNP) levels are simple and objective measures of cardiac function. These measurements can be used to diagnose heart failure, including diastolic dysfunction, and using them has been shown to save money in the emergency department setting. The high negative predictive value of BNP tests is particularly helpful for ruling out heart failure. Treatment with angiotensin-converting enzyme inhibitors, angiotensin-II receptor blockers, spironolactone, and diuretics reduces BNP levels, suggesting that BNP testing may have a role in monitoring patients with heart failure. However, patients with treated chronic stable heart failure may have levels in the normal range (i.e., BNP less than 100 pg per mL and N-terminal proBNP less than 125 pg per mL in patients younger than 75 years). Increases in BNP levels may be caused by intrinsic cardiac dysfunction or may be secondary to other causes such as pulmonary or renal diseases (e.g., chronic hypoxia). BNP tests are correlated with other measures of cardiac status such as New York Heart Association classification. BNP level is a strong predictor of risk of death and cardiovascular events in patients previously diagnosed with heart failure or cardiac dysfunction.

The intra-aortic balloon pump in heart failure management : implications for nursing practice

Management of acute heart failure is an important consideration in critical care. Mechanical support of the failing heart is crucial for improving health outcomes. The most common Australasian application of intraaortic balloon counterpulsation (IABP) is in the setting of cardiogenic shock. High end users of IABP (>37/annum) demonstrate significantly lower mortality for cardiogenic shock managed with IABP (p <0.001) in contrast to hospitals which employ limited IABP (<4/annum). This underscores the importance of proficiency in managing patient receiving IABP support. Nurses play a crucial role in carding for patients with acute heart failure. This paper summarises care considerations for management of the IABP.
