A Workflow towards the Reproducible Identification and Quantitation of Protein Carbonylation Sites in Human PlasmaEcheverri, Juan Camilo Rojas, Milkovska-Stamenova, Sanja, Hoffmann, Ralf 24 April 2023 (has links)
Protein carbonylation, a marker of excessive oxidative stress, has been studied in the context of multiple human diseases related to oxidative stress. The variety of post-translational carbonyl modifications (carbonyl PTMs) and their low concentrations in plasma challenge their reproducible identification and quantitation. However, carbonyl-specific biotinylated derivatization tags (e.g., aldehyde reactive probe, ARP) allow for targeting carbonyl PTMs by enriching proteins and peptides carrying these modifications. In this study, an oxidized human serum albumin protein model (OxHSA) and plasma from a healthy donor were derivatized with ARP, digested with trypsin, and enriched using biotin-avidin affinity chromatography prior to nano reversed-phase chromatography coupled online to electrospray ionization tandem mass spectrometry with travelling wave ion mobility spectrometry (nRPC-ESI-MS/MS-TWIMS). The presented workflow addresses several analytical challenges by using ARP-specific fragment ions to reliably identify ARP peptides. Furthermore, the reproducible recovery and relative quantitation of ARP peptides were validated. Human serum albumin (HSA) in plasma was heavily modified by a variety of direct amino acid oxidation products and adducts from reactive carbonyl species (RCS), with most RCS modifications being detected in six hotspots, i.e., Lys10, Lys190, Lys199, Lys281, Lys432, and Lys525 of mature HSA.

L'œuvre poétique tardive de Jean Hans Arp (1886-1966) / Jean Hans Arp’s Late Poetry (1886-1966)Mareuge, Agathe 10 October 2014 (has links)
L’étude de l’oeuvre poétique tardive de l’artiste Jean Hans Arp (1886-1966) révèle que l’opposition entre non-sens et sens, au moyen de laquelle est souvent analysé le passage de sa production dada à sa poésie des années cinquante et soixante, n’a pas lieu d’être. L’introduction d’une cohérence aux plans formel et structurel permet au plan sémantique le maintien de la plurivocité et de la contradiction. L’analyse des formes poétiques arpiennes montre l’existence d’une invention et d’une variété formelles intactes dans la production tardives, entre actualisation de formes anciennes et innovation. Cette tension anime également son activité anthologique et éditoriale, comprise comme élément constituant de sa poétique tardive : le poète déploie des stratégies visant à constituer, entre soixante et quatre-vingts ans, une oeuvre réflexive, intégrant les cinquante années de production antérieure, mais en déjouant constamment les écueils de l’(auto-)monumentalité. Le rapport entretenu avec la réalité extérieure au langage connaît un bouleversement référentiel après 1943-1945. La critique accrue de la rationalité occidentale et l’exigence d’expression subjective conduisent à la mise en place d’un discours poétique sur le monde et sur les capacités du langage, une « cosmogonie de poche » à la fois humble et démiurgique. Elle consiste en une confiance inaltérée dans le pouvoir créateur du langage poétique, capable de créer d’autres mondes. Cette modernité radicale d’Arp, exacerbée car revendiquée, le situe de façon originale dans le contexte du devenir des avant-gardes européennes après 1945 et met en lumière la spécificité de son appartenance à une génération de transition. / A close study of Jean Hans Arp’s late poetry exposes the inadequacy of the traditional opposition between non-sense and sense, which is frequently used to analyse the transition from his Dada production to the poetic works of the 1950s and the 1960s. By introducing a formal and structural coherence, the poet manages to preserve plurivocity and contradiction on a semantic level. Considering the specificities of Arp’s late poetic forms, the study shows that invention and variety are as vivid then as they were during Dada Zurich, based on both innovation and actualisation of former techniques. This tension is inherent to his anthological and editorial activity as well, which is considered here as a key element of his late poetics. In his sixties and up until his eighties, the poet develops strategies aimed at constituting a reflexive work which integrates the earlier production while always avoiding the trap of (self-) monumentalisation. After 1943-1945, the relationship between Arp's poetry and reality outside the language undergoes a profound referential change. His increasing criticism of western rationalism and need for subjective expression, without returning to neo-romanticism, form the basis for a poetic discourse on the world and the possibilities of language, a “pocket cosmogony” that is both humble and demiurgic”. The latter hinges on an unwavering faith in the creative power of the poetic word and its ability to generate other worlds. This radical modernity, consciously asserted, locates Arp’s late work as an original experiment in the context of the avant-gardes post-1945, highlighting his specific itinerary within a transitional generation.

Performance Optimization of Network Protocols for IEEE 802.11s-based Smart Grid CommunicationsSaputro, Nico 16 June 2016 (has links)
The transformation of the legacy electric grid to Smart Grid (SG) poses numerous challenges in the design and development of an efficient SG communications network. While there has been an increasing interest in identifying the SG communications network and possible SG applications, specific research challenges at the network protocol have not been elaborated yet. This dissertation revisited each layer of a TCP/IP protocol stack which basically was designed for a wired network and optimized their performance in IEEE 802.11s-based Advanced Metering Infrastructure (AMI) communications network against the following challenges: security and privacy, AMI data explosion, periodic simultaneous data reporting scheduling, poor Transport Control Protocol (TCP) performance, Address Resolution Protocol (ARP) broadcast, and network interoperability. To address these challenges, layered and/or cross-layered protocol improvements were proposed for each layer of TCP/IP protocol stack. At the application layer, a tree-based periodic time schedule and a time division multiple access-based scheduling were proposed to reduce high contention when smart meters simultaneously send their reading. Homomorphic encryption performance was investigated to handle AMI data explosion while providing security and privacy. At the transport layer, a tree-based fixed Retransmission Timeout (RTO) setting and a path-error aware RTO that exploits rich information of IEEE 802.11s data-link layer path selection were proposed to address higher delay due to TCP mechanisms. At the network layer, ARP requests create broadcast storm problems in IEEE 802.11s due to the use of MAC addresses for routing. A secure piggybacking-based ARP was proposed to eliminate this issue. The tunneling mechanisms in the LTE network cause a downlink traffic problem to IEEE 802.11s. For the network interoperability, at the network layer of EPC network, a novel UE access list was proposed to address this issue. At the data-link layer, to handle QoS mismatch between IEEE 802.11s and LTE network, Dual Queues approach was proposed for the Enhanced Distributed Channel Access. The effectiveness of all proposed approaches was validated through extensive simulation experiments using a network simulator. The simulation results showed that the proposed approaches outperformed the traditional TCP/IP protocols in terms of end to end delay, packet delivery ratio, throughput, and collection time.
