Traduccions cantables per a corals infantils catalanes: el repertori anglès-català del SCIC

En primer lloc els objectius que s’estableixen en aquest estudi són: Valorar la importància de la melodia, dels accents i la musicalitat del text en les cançons traduïdes analitzades. Plantejar la necessitat de la traducció de cançons infantils. Analitzar les traduccions existents de l’anglès al català del repertori de cançons infantils que es canten a les corals infantils. Relacionar poesia infantil i cançó. Visualitzar l’ús de la cançó infantil per a l’ensenyament dels infants, tant pel que fa a la transmissió de valors com per a l’ensenyament de llengües. La metodologia utilitzada fa referència a dos aspectes. El mètode qualitatiu amb la lectura d’articles i la bibliografia seleccionada i el mètode quantitatiu amb l’anàlisi de tres entrevistes i vint-i-una enquestes a responsables de corals infantils. En aquest estudi ofereixo l’estat de la qüestió sobre la traducció de cançons, amb especial atenció a la traducció de cançons per ser cantades. Després s’aborda la traducció de cançons infantils per ser cantades, per acabar especificant el tema d’aquest treball d’investigació en concret: la traducció de cançons infantils per ser cantades, amb l’estudi de traduccions de l’anglès al català de cançons cantades per corals infantils de Catalunya, i se n’ubica el context: el moviment coral infantil a Catalunya. Per a la confecció d’aquest estudi s’ha fet un recull de vint-i-set cançons traduïdes (anglès-català) que canten les corals infantils de Catalunya aplegades en el Secretariat de Corals Infantils de Catalunya (SCIC). Se n’ha seleccionat les cançons traduïdes de l’anglès al català, incloent-hi la partitura, la lletra original i la traducció. Aquest recull permet establir un lligam entre la traducció, la música i la pedagogia musical a Catalunya, els tres eixos principals d’aquest treball. D’aquestes cançons se n’han analitzat tres seguint els criteris establerts per autors com Peter Low, per la seva àmplia experiència en la traducció de música vocal. Els criteris són referents al ritme, rima, cantabilitat, naturalitat i sentit. Per tal de fer aquest estudi es van portar a terme tres entrevistes a traductors de cançons infantils: Enriqueta Anglada, Maria Martorell i Josep Vigo. Per valorar l’ús de cançons traduïdes dins del moviment coral infantil en l’actualitat i de manera més global, el treball inclou una enquesta, adreçada a directors de cors infantils, resposta per 21 cors. Aquestes enquestes palesen els canvis produïts amb el temps respecte a la necessitat de traduir cançons, ja que actualment la traducció no és tant important tot i que es continua valorant la seva importància, sobretot per afavorir la comprensió del que es canta. Però alhora es referma el desig de cantar en l’idioma original (especialment en el cas de l’anglès), quan aquest idioma l’entén qui dirigeix o interpreta la cançó, quan aquest fet es veu com a repte, o quan es prioritza la relació original entre música i text.

Crosstalk between xenobiotics metabolism and circadian clock.

Many aspects of physiology and behavior in organisms from bacteria to man are subjected to circadian regulation. Indeed, the major function of the circadian clock consists in the adaptation of physiology to daily environmental change and the accompanying stresses such as exposition to UV-light and food-contained toxic compounds. In this way, most aspects of xenobiotic detoxification are subjected to circadian regulation. These phenomena are now considered as the molecular basis for the time-dependence of drug toxicities and efficacy. However, there is now evidences that these toxic compounds can, in turn, regulate circadian gene expression and thus influence circadian rhythms. As food seems to be the major regulator of peripheral clock, the possibility that food-contained toxic compounds participate in the entrainment of the clock will be discussed.

Differential contribution of mitochondria, NADPH oxidases, and glycolysis to region-specific oxidant stress in the anoxic-reoxygenated embryonic heart.

The ability of the developing myocardium to tolerate oxidative stress during early gestation is an important issue with regard to possible detrimental consequences for the fetus. In the embryonic heart, antioxidant defences are low, whereas glycolytic flux is high. The pro- and antioxidant mechanisms and their dependency on glucose metabolism remain to be explored. Isolated hearts of 4-day-old chick embryos were exposed to normoxia (30 min), anoxia (30 min), and hyperoxic reoxygenation (60 min). The time course of ROS production in the whole heart and in the atria, ventricle, and outflow tract was established using lucigenin-enhanced chemiluminescence. Cardiac rhythm, conduction, and arrhythmias were determined. The activity of superoxide dismutase, catalase, gutathione reductase, and glutathione peroxidase as well as the content of reduced and oxidized glutathione were measured. The relative contribution of the ROS-generating systems was assessed by inhibition of mitochondrial complexes I and III (rotenone and myxothiazol), NADPH oxidases (diphenylene iodonium and apocynine), and nitric oxide synthases (N-monomethyl-l-arginine and N-iminoethyl-l-ornithine). The effects of glycolysis inhibition (iodoacetate), glucose deprivation, glycogen depletion, and lactate accumulation were also investigated. In untreated hearts, ROS production peaked at 10.8 ± 3.3, 9 ± 0.8, and 4.8 ± 0.4 min (means ± SD; n = 4) of reoxygenation in the atria, ventricle, and outflow tract, respectively, and was associated with arrhythmias. Functional recovery was complete after 30-40 min. At reoxygenation, 1) the respiratory chain and NADPH oxidases were the main sources of ROS in the atria and outflow tract, respectively; 2) glucose deprivation decreased, whereas glycogen depletion increased, oxidative stress; 3) lactate worsened oxidant stress via NADPH oxidase activation; 4) glycolysis blockade enhanced ROS production; 5) no nitrosative stress was detectable; and 6) the glutathione redox cycle appeared to be a major antioxidant system. Thus, the glycolytic pathway plays a predominant role in reoxygenation-induced oxidative stress during early cardiogenesis. The relative contribution of mitochondria and extramitochondrial systems to ROS generation varies from one region to another and throughout reoxygenation.

Quantitative genetics of sleep in inbred mice.

The timing and the organization of sleep architecture are mainly controlled by the circadian system, while sleep need and intensity are regulated by a homeostatic process. How independent these two systems are in regulating sleep is not well understood. In contrast to the impressive progress in the molecular genetics of circadian rhythms, little is known about the molecular basis of sleep. Nevertheless, as summarized here, phenotypic dissection of sleep into its most basic aspects can be used to identify both the single major genes and small effect quantitative trait loci involved. Although experimental models such as the mouse are more readily amenable to genetic analysis of sleep, similar approaches can be applied to humans.

Resurgence of inner solutions for perturbations of the McMillan map

A sequence of “inner equations” attached to certain perturbations of the McMillan map was considered in [MSS09], their solutions were used in that article to measure an exponentially small separatrix splitting. We prove here all the results relative to these equations which are necessary to complete the proof of the main result of [MSS09]. The present work relies on ideas from resurgence theory: we describe the formal solutions, study the analyticity of their Borel transforms and use ´Ecalle’s alien derivations to measure the discrepancy between different Borel-Laplace sums.

Objectifying psychomental stress in the workplace--an example.

BACKGROUND: Psychomental stress is a major source of illness and reduced productivity. Data objectifying physiological stress responses are scarce. We studied salivary cortisol levels in a highly stressful environment, the pediatric critical care unit. The aim was to identify targets for organizational changes, to implement these changes and to assess their impact on cortisol levels. DESIGN: Repeated measurements observational cohort study (before and after intervention). SUBJECTS: 84 nurses working in two independent teams (A and B) in a 19 bed pediatric intensive care unit. Between study periods team A experienced a major exchange of experienced staff while the turnover rate in team B remained average. MEASUREMENTS AND INTERVENTIONS: Salivary cortisol samples were collected every 2 h and after stressful events. Nurses in study period I showed elevated cortisol levels at the beginning of the late shift, interpreted as an anticipatory stress reaction. To ease conditions during the early part of the late shift (conflicting tasks, noise and crowding), we postponed the afternoon ward round, limited non-urgent procedures and introduced a change in visiting hours. The early shift, which was not affected by the intervention, served as control. MAIN RESULTS: Both crude and adjusted analysis revealed a decrease of cortisol levels at the beginning of the late shift in team B (p = 0.0009), but not in team A (p = 0.464). The control situation showed no difference between teams and study periods. INTERPRETATION: We demonstrated reduced cortisol secretions in one team following organizational changes, which was probably overridden by the disruption of social coherence in the second team.

Long-term use and tolerability of irbesartan for control of hypertension.

In this review, we discuss the pharmacological and clinical properties of irbesartan, a noncompetitive angiotensin II receptor type 1 antagonist, successfully used for more than a decade in the treatment of essential hypertension. Irbesartan exerts its antihypertensive effect through an inhibitory effect on the pressure response to angiotensin II. Irbesartan 150-300 mg once daily confers a lasting effect over 24 hours, and its antihypertensive efficacy is further enhanced by the coadministration of hydrochlorothiazide. Additionally and partially beyond its blood pressure-lowering effect, irbesartan reduces left ventricular hypertrophy, favors right atrial remodeling in atrial fibrillation, and increases the likelihood of maintenance of sinus rhythm after cardioversion in atrial fibrillation. In addition, the renoprotective effects of irbesartan are well documented in the early and later stages of renal disease in type 2 diabetics. Furthermore, both the therapeutic effectiveness and the placebo-like side effect profile contribute to a high adherence rate to the drug. Currently, irbesartan in monotherapy or combination therapy with hydrochlorothiazide represent a rationale pharmacologic approach for arterial hypertension and early-stage and late-stage diabetic nephropathy in hypertensive type II diabetics.

Effects of flecainide on exercise-induced ventricular arrhythmias and recurrences in genotype-negative patients with catecholaminergic polymorphic ventricular tachycardia.

BACKGROUND: Conventional therapy with beta-blockers is incompletely effective in preventing arrhythmic events in patients with catecholaminergic polymorphic ventricular tachycardia (CPVT). We have previously discovered that flecainide in addition to conventional drug therapy prevents ventricular arrhythmias in patients with genotype-positive CPVT. OBJECTIVE: To study the efficacy of flecainide in patients with genotype-negative CPVT. METHODS: We studied the efficacy of flecainide for reducing ventricular arrhythmias during exercise testing and preventing arrhythmia events during long-term follow-up. RESULTS: Twelve patients with genotype-negative CPVT were treated with flecainide. Conventional therapy failed to control ventricular arrhythmias in all patients. Flecainide was initiated because of significant ventricular arrhythmias (n = 8), syncope (n = 3), or cardiac arrest (n = 1). At the baseline exercise test before flecainide, 6 patients had ventricular tachycardia and 5 patients had bigeminal or frequent ventricular premature beats. Flecainide reduced ventricular arrhythmias at the exercise test in 8 patients compared to conventional therapy, similar to that in patients with genotype-positive CPVT in our previous report. Notably, flecainide completely prevented ventricular arrhythmias in 7 patients. Flecainide was continued in all patients except for one who had ventricular tachycardia at the exercise test on flecainide. During a follow-up of 48±94 months, arrhythmia events (sudden cardiac death and aborted cardiac arrest) associated with noncompliance occurred in 2 patients. Flecainide was not discontinued owing to side effects in any of the patients. CONCLUSIONS: Flecainide was effective in patients with genotype-negative CPVT, suggesting that spontaneous Ca(2+) release from ryanodine channels plays a role in arrhythmia susceptibility, similar to that in patients with genotype-positive CPVT.

Individualització de la programació docent de Fonaments de Computadors

La metodologia docent impulsada per la creació d’un Espai Europeu d’Ensenyament Superior comú implica tenir en compte el treball de l’estudiant. En aquest sentit, resulta molt convenient facilitar a l’alumnat de primers cursos l’adaptació a una docència que s’organitza en crèdits ECTS i que se centra en el procés d’aprenentatge dels estudiants. Per aquest motiu, l’objectiu d’aquest projecte ha estat que assumissin un grau més elevat de responsabilitat en l’aprenentatge i que adquirissin una competència més gran en l’organització del temps d’acord amb els programes docents de les assignatures que cursessin. Per aconseguir-ho, s’ha creat un entorn de presentació de les guies docents basat en les agendes d’activitats d’aprenentatge. Aquestes agendes són, de fet, planificacions de les activitats presencials i no presencials que han de dur a terme els estudiants per assolir els objectius de cadascuna de les assignatures que fan. Perquè siguin efectives, han de ser el més individuals possibles i amb la informació suficient com perquè les activitats es puguin dur a terme. Així, els alumnes disposen d’una veritable agenda particular del què han de fer i quan per seguir una assignatura determinada. Com a resultat del projecte s’ha proposat una organització de la informació d’una assignatura que facilita tant la gestió de les guies docents com la creació d’agendes d’activitats d’aprenentatge, s’ha establert una metodologia de presentació dels programes docents amb suport de web perquè sigui de fàcil consulta i en els que els vincles de cada activitat s’activen segons el ritme del curs i, finalment, s’ha aplicat tot per al cas de l’assignatura de Fonaments de computadors, aconseguint que l’alumnat s’acostumi a seguir les agendes d’activitats i, consegüentment, a millorar el rendiment acadèmic de l’assignatura, que era el que, es pretenia originalment.

Guidelines for the clinical management of atrial fibrillation: a practical perspective.

Since the management of atrial fibrillation may be difficult in the individual patient, our purpose was to develop simple clinical recommendations to help the general internist manage this common clinical problem. Systematic review of the literature with evaluation of data-related evidence and framing of graded recommendations. Atrial fibrillation affects some 1% of the population in Western countries and is linked to a significant increase in morbidity and mortality. The management of atrial fibrillation requires individualised evaluation of the risks and benefits of therapeutic modalities, relying whenever possible on simple and validated tools. The two main points requiring a decision in clinical management are 1) whether or not to implement thromboembolic prevention therapy, and 2) whether preference should be given to a "rate control" or "rhythm control" strategy. Thromboembolic prophylaxis should be prescribed after individualised risk assessment: for patients at risk, oral anticoagulation with warfarin decreases the rate of embolic complications by 60% and aspirin by 20%, at the expense of an increased incidence of haemorrhagic complications. "Rate control" and "rhythm control" strategies are probably equivalent, and the choice should also be made on an individualised basis. To assist the physician in making his choices for the care of an atrial fibrillation patient we propose specific tables and algorithms, with graded recommendations. On the evidence of data from the literature we propose simple algorithms and tables for the clinical management of atrial fibrillation in the individual patient.

Sleep EEG changes after middle cerebral artery infarcts in mice: different effects of striatal and cortical lesions.

STUDY OBJECTIVES: Hemispheric stroke in humans is associated with sleep-wake disturbances and sleep electroencephalogram (EEG) changes. The correlation between these changes and stroke extent remains unclear. In the absence of experimental data, we assessed sleep EEG changes after focal cerebral ischemia of different extensions in mice. DESIGN: Following electrode implantation and baseline sleep-wake EEG recordings, mice were submitted to sham surgery (control group), 30 minutes of intraluminal middle cerebral artery (MCA) occlusion (striatal stroke), or distal MCA electrocoagulation (cortical stroke). One and 12 days after stroke, sleep-wake EEG recordings were repeated. The EEG recorded from the healthy hemisphere was analyzed visually and automatically (fast Fourier analysis) according to established criteria. MEASUREMENTS AND RESULTS: Striatal stroke induced an increase in non-rapid eye movement (NREM) sleep and a reduction of rapid eye movement sleep. These changes were detectable both during the light and the dark phase at day 1 and persisted until day 12 after stroke. Cortical stroke induced a less-marked increase in NREM sleep, which was present only at day 1 and during the dark phase. In cortical stroke, the increase in NREM sleep was associated in the wake EEG power spectra, with an increase in the theta and a reduction in the beta activity. CONCLUSION: Cortical and striatal stroke lead to different sleep-wake EEG changes in mice, which probably reflect variable effects on sleep-promoting and wakefulness-maintaining neuronal networks.

Primaries the unifying force

We present a formal model of intra-party politics to explain candidate selection within parties. We think of parties as heterogeneous groups of individuals who aim to implement a set of policies but who differ in their priorities. When party heterogeneity is too large, parties are in danger of splitting into smaller yet more homogeneous groups. In this context we argue that primaries can have a unifying role if the party elite cannot commit to policy concessions. Our model shows how alignment in the preferred policies of various factions within a party, the relative weight of each of these factions and the electoral system interact to create incentives for the adoption of primary elections. We discuss the existing empirical literature in the light of our theoretical predictions to provide a new, structured perspective on the adoption of primary elections.

Confounding effects of heart rate on pulse wave velocity in paced patients with a low degree of atherosclerosis.

BACKGROUND: Pulse wave velocity (PWV), an index of arterial wall stiffness, is modulated by blood pressure (BP). Whether heart rate (HR) is also a modulator of PWV is controversial. Recent research involving mainly patients with high aortic PWV have found either no change or a positive correlation between the two. Given that PWV is increasingly being measured in cardiovascular studies, the relationship between HR and PWV should be known in patients with preserved arterial wall elasticity. OBJECTIVE: The aim of this study was to evaluate the importance of HR as a determinant of the variability in PWV in patients with a low degree of atherosclerosis. DESIGN AND METHODS: Fourteen patients (five female, nine male; aged 68 +/- 8 years) were evaluated post pacemaker implantation due to sick sinus or carotid hypersensitivity syndromes. Carotid-femoral PWV was measured at rest and during atrial pacing at 80, 90 and 100 bpm (paced HR). Arterial femoral blood flow (AFBF) was measured by echodoppler. RESULTS: PWV increased from 6.2 +/- 1.5 m/s (mean +/- SD) during resting sinus rhythm (HR 62 +/- 8 bpm; mean +/- SD) to 6.8 +/- 1.0, 7.0 +/- 0.9, and 7.6 +/- 1.1 m/s at pacing rates of 80, 90 and 100 bpm, respectively (P < 0.0001). Systolic (SBP) and mean blood pressure (MBP) remained constant at all HR levels, whereas AFBF increased in a linear fashion. CONCLUSIONS: These results demonstrate that even in patients with a low degree of atherosclerosis, HR is a potential modulator of carotid-femoral PWV.
