Abstract:

What constitutes a concert? While many have played with the form, the basics – performers and audience in a shared space – seemed self-evident. However, at a time when restrictions limit or prevent gatherings of performers and audience, this question has assumed new significance. Indeed, the area of live music performance has borne the brunt of many of the ongoing uncertainties, changes and debates of recent months. In the midst of disappointing and unsettling news about cancellations and postponements, it was a welcome relief to read that Psappha decided to go ahead with their 2020–21 concert series. As one of the UK's preeminent contemporary music ensembles, Psappha's influence extends far beyond its Manchester home, reaching a worldwide audience via its YouTube channel. Psappha's current programme is testament to the ensemble's vision, juxtaposing well-known monoliths from the twentieth-century repertoire against works by emerging composers and those whose music is heard less often in the UK.

Abstract:

You're probably wondering why a violin concerto was given its UK première by the chamber ensemble Psappha? An informative programme note by Paul Griffiths for the 15 February concert revealed that Swedish composer Klas Torstensson (b. 1951) had in fact written a much longer, though still compactly scored, work in 2010 and had ‘squashed it down’ in length and further reduced the number of players. The work's full title is Pocket Size Violin Concerto – scored for soloist with unconducted accompaniment from piano, flute, and cello. Whilst compression of this kind is not uncommon in other branches of the arts, and concision is a noble artistic aim, one's fear was that such drastic pruning might have short-circuited the music's arguments. Happily this proved unfounded; and whilst the original half-hour's duration might have been pushing it a bit, the modified version (at a whisker under 17 minutes) seemed just about right.

Abstract:

Contemporary music ensemble Psappha gave three world premières in a concert at the University of Manchester's Cosmo Rodewald Hall on 8 March 2013. Their programme began with first performances of brief works by two young composers connected with the University. I Lost My Way in Dixieland, by Thomas Jarvis (b.1991), was a deftly realized deconstruction and reinvention of a popular jazz style, with a throwaway ending that made an apt parting gesture for a witty and enjoyable pastiche. And Sempadan, by Sayyid Shafiee (b.1987), made effective use of offstage trumpet and trombone interacting with on-stage clarinet, percussion and double bass, to suggest the concept of two different but complementary cultures.

Abstract:

Mitochondrial dysfunction plays a pivotal role in the Alzheimer’s Disease (AD) pathology. Disrupted mitochondrial dynamics (i.e., fusion/fission balance), which are essential for normal mitochondria structure and function, are documented in AD. Caveolin-1 (Cav-1), a membrane/lipid raft (MLR) scaffolding protein regulates metabolic pathways in several different cell types such as hepatocytes and cancer cells. Previously, we have shown decreased expression of Cav-1 in the hippocampus of 9-month (m) old PSAPP mice, while hippocampal overexpression of neuron-targeted Cav-1 using the synapsin promoter (i.e., SynCav1) preserved cognitive function, neuronal morphology, and synaptic ultrastructure in 9 and 12 m PSAPP mice. Considering the central role of energy production in maintaining normal neuronal and synaptic function and survival, the present study reveals that PSAPP mice exhibit disrupted mitochondrial distribution, morphometry, and respiration. In contrast, SynCav1 mitigates mitochondrial damage and loss and enhances mitochondrial respiration. Furthermore, by examining mitochondrial dynamics, we found that PSAPP mice showed a significant increase in the phosphorylation of mitochondrial dynamin-related GTPase protein (DRP1), resulting in excessive mitochondria fragmentation and dysfunction. In contrast, hippocampal delivery of SynCav1 significantly decreased p-DRP1 and augmented the level of the mitochondrial fusion protein, mitofusin1 (Mfn1) in PSAPP mice, a molecular event, which may mechanistically explain for the preserved balance of mitochondria fission/fusion and metabolic resilience in 12 m PSAPP-SynCav1 mice. Our data demonstrate the critical role for Cav-1 in maintaining normal mitochondrial morphology and function through affecting mitochondrial dynamics and explain a molecular and cellular mechanism underlying the previously reported neuroprotective and cognitive preservation induced by SynCav1 in PSAPP mouse model of AD.

Abstract:

The calculated fraction of receptor ligands available for blood–brain barrier passage in vivo (favail) may differ from in vitro (feq) measurements. This study evaluates the protein–ligand interaction for iomazenil and flumazenil in rats by comparing feq and favail. Repeated measurements of blood–brain barrier permeability for two benzodiazepine antagonists were performed in 44 rats by the double-indicator technique. Cerebral blood flow was measured by intracarotid Xe-injection. The apparent permeability–surface product (PSapp) was measured while CBF or bolus composition was changed. Comparison of PSapp obtained in the absence and presence of 5% albumin in the injectate yielded favail, whereas feq was measured by equilibrium dialysis. Iomazenil and flumazenil favail was 62% and 82%, respectively, whereas feq was significantly lower, 42% and 61%. The PSapp for iomazenil and flumazenil increased significantly by 89% and 161% after relative CBF increases of 259% and 201%, respectively. The results demonstrate that application of feq in neuroreceptor studies underestimates the plasma input function to the brain. Model simulations render possible that the differences between favail and feq as well as the effect of CBF on PSapp can be caused by capillary heterogeneity.

Abstract:

Amyloid precursor protein (APP) proteolysis is required for production of amyloid-β (Aβ) peptides that comprise β-amyloid plaques in the brains of patients with Alzheimer disease (AD). Here, we tested whether the experimental agent methylene blue (MB), used for treatment of methemoglobinemia, might improve AD-like pathology and behavioral deficits. We orally administered MB to the aged transgenic PSAPP mouse model of cerebral amyloidosis and evaluated cognitive function and cerebral amyloid pathology. Beginning at 15 months of age, animals were gavaged with MB (3 mg/kg) or vehicle once daily for 3 months. MB treatment significantly prevented transgene-associated behavioral impairment, including hyperactivity, decreased object recognition, and defective spatial working and reference memory, but it did not alter nontransgenic mouse behavior. Moreover, brain parenchymal and cerebral vascular β-amyloid deposits as well as levels of various Aβ species, including oligomers, were mitigated in MB-treated PSAPP mice. These effects occurred with inhibition of amyloidogenic APP proteolysis. Specifically, β-carboxyl-terminal APP fragment and β-site APP cleaving enzyme 1 protein expression and activity were attenuated. Additionally, treatment of Chinese hamster ovary cells overexpressing human wild-type APP with MB significantly decreased Aβ production and amyloidogenic APP proteolysis. These results underscore the potential for oral MB treatment against AD-related cerebral amyloidosis by modulating the amyloidogenic pathway.

Abstract:

The main goal of this paper is to survey the interpretive possibilities for Psappha by Iannis Xenakis, a multiple percussion solo piece whose graphic score, along with the instructions on the Explanatory Note, provides several openings for the participation of the performer. Given the historical importance of the work and compositional innovations by Xenakis, this important solo has been widely presented since its composition, resulting in very distinct performances. However, after searching for related studies and analyzing performances, it was observed that some of the interpretive possibilities inherent to the score have been little explored. In order to speculate on such possibilities, this study sought, through a musical analysis combined with performance practices, to propose instrumentation and techniques that could enable the interpretation of the different meanings attributed to the accents in Psappha, poorly explored until now. As a result of this study, I will present considerations concerning the various nalyses of the work and performance records studied. Moreover, I will share further notes, possibilities and technical solutions devised from personal interpretive studies.<br>O objetivo central desta dissertação é fazer um levantamento de possibilidades interpretativas em Psappha, de Iannis Xenakis, obra escrita para percussão múltipla solo cuja partitura gráfica, juntamente com as instruções apresentadas na nota explicativa, fornece diversas aberturas para a participação do intérprete. Devido à importância histórica da obra e às inovações composicionais de Xenakis, desde sua estreia este importante solo tem sido amplamente apresentado, demonstrando em suas performances resultados bastante distintos. Entretanto, após pesquisa de inúmeros trabalhos relacionados e análise de diversas performances, observou-se que algumas possibilidades interpretativas inerentes à partitura ainda foram pouco exploradas. Com objetivo de especular sobre tais liberdades, esta pesquisa buscou, através de uma análise musical aliada a estudos de performance, propor instrumentações e técnicas de execução que viabilizassem sobretudo a interpretação dos diferentes significados atribuídos às notas acentuadas em Psappha, até hoje pouco explorados. Como resultado desta pesquisa, apresento considerações relativas às diversas análises da obra e aos registros de performance estudados. Além disso, compartilho alguns apontamentos, possibilidades e soluções técnicas alcançadas em estudos interpretativos pessoais.
