Wache Videolaryngoskopie

2016

Introduction Awake video laryngoscopy is a novel option in airway management that is drawing more and more attention as an alternative to awake endoscopic guided intubation.Main issues: Intubation under preserved spontaneous breathing is the safest method to secure the expected difficult airway. In direct comparisons to awake flexible endoscopic intubation, awake video laryngoscopy achieves satisfactory intubation times and a high acceptance of patients and anesthesiologists. Specific cases, in particular very limited mouth opening or sub-glottic masses, require awake flexible endoscopic intubation. Sufficient topical anesthesia and a sophisticated sedation protocol are prerequisites for su…

Genitori e bambini: lasciamoli guardare in pace i loro cartoni

2017

Che differenza c'è fra l'analisi semiotica dei cartoni animati e la sua "versione facile"? In rete e nell'editoria si diffondono sempre più spesso testi a commento dei cartoni animati che piuttosto che aprire alla complessità del mondo tendono a costituire una volontà di controllo e di imposizione di visioni ideologiche pregresse.

Zum Spannungsverhältnis zwischen ästhetischen und linguistischen Qualitätskriterien literarischer Übersetzungen

2017

Today, literary translation occupies a special place in the translation theory, despite the fact that some researchers consider the dichotomous division within the discipline into literary and non-literary texts as resolved and unjustified. This article is an attempt to present a breakdown of selected aesthetic and linguistic criteria for the quality assessment of literary translations in order to consider, on this basis, the validity of the interdisciplinary approach to the criticism of translation of literary texts. The analysis is focused in particular on the translation quality parameters established by Sigrid Kupsch-Losereit. It is then followed by the reflection on the possibilities t…

Synthesis of CO2-responsive polymers by post-polymerization modification

2014

Abstract We describe a general method to synthesize a double responsive polymer, exhibiting a temperature and CO 2 responsive behavior. The polymer derived from a controlled radical polymerization technique of pentafluorophenyl acrylate (PFPA), followed by a sequential post-polymerization modification of a CO 2 responsive- and thermo-responsive amines. Utilizing this approach three double responsive copolymers were synthesized, poly(3- N′,N′ -dimethylaminopropyl acrylamide- co - N -isopropyl acrylamide) (poly(DMPA- co -NIPAM)), poly( L -Arginine methyl ester acrylamide- co - N -isopropyl acrylamide) (poly(AME- co -NIPAM)) and poly( L -Arginine methyl ester acrylamide- co - N -cyclopropyl ac…

Temperature-responsive inclusion complex of cationic PNIPAAM diblock copolymer and γ-cyclodextrin

2012

Aqueous mixtures of γ-cyclodextrin (γ-CD) and the thermosensitive cationic diblock copolymer poly(N-isopropylacrylamide)-b-poly(3-acrylamidopropyl)trimethylammonium chloride (PNIPAAM24-b-PAMPTAM(+)9) or the PNIPAAM homopolymer PNIPAAM47 have been investigated using various experimental methods. Solid γ-CD–polymer inclusion complexes (pseudopolyrotaxanes) form at ambient temperatures in fairly concentrated CD solutions. The NMR measurements showed that the stoichiometry of the inclusion complexes is close to two NIPAAM units per CD molecule. The cationic block of the copolymer is not incorporated into the CD cavity. Synchrotron radiation X-ray diffraction spectra of the solid inclusion compl…

Temperature and light sensitive copolymers containing azobenzene moieties prepared via a polymer analogous reaction

2009

Abstract Four different series of polyacrylamides containing different amounts of azobenzene moieties have been synthesized via a polymer analogous reaction of poly(pentafluorophenylacrylate) (PPFPA). All copolymers were designed to exhibit a lower critical solution temperature (LCST) in aqueous solution, which was dependent on (i) the amount of incorporated chromophoric azobenzene groups and (ii) the isomerization state of the respective azobenzene group. Higher LCST values were measured for UV-irradiated solutions of the copolymers in comparison to the non-irradiated copolymer solutions. A maximum difference in the LCST of up to 7 °C was found for the copolymer poly(N,N-dimethylacrylamide…

Morphological transformations in a dually thermoresponsive coil-rod-coil bioconjugate.

2013

We report the conformational and assembly behavior of a thermoresponsive triblock biohybrid conjugate under aqueous conditions. The triblock comprises of poly(diethylene glycol methyl ether methacrylate) (PDEGMEMA) conjugated to the ends of a triple-helix forming collagen-like peptide. The circular dichroism (CD) experiment confirms the ability of the collagen-like peptide middle block to assemble as a triple helix in the hybrid conjugate. Above the LCST (∼35 °C), the collapse of the thermoresponsive PDEGMEMA polymer at the ends of the peptide domain resulted in a concomitant increase in the conformational stability of the peptide domain towards thermal denaturation. Upon cooling back, the …

PNIPAM Copolymers Containing Light-Responsive Chromophores: A Method Toward Molecular Logic Gates

2010

A series of thermo-responsive PNIPAM copolymers containing different amounts of fulgimide moieties has been synthesized via a polymer analogous reaction of poly(pentafluorophenyl acrylate). All copolymers were designed to exhibit a lower critical solution temperature (LCST) in water, which was only weakly dependent on the amount of incorporated chromophoric fulgimide groups. The copolymers showed a photocyclization of the fulgimide side groups upon irradiation with UV-light accompanied with a color change. The closed form of the chromophore had a halftime of 136 min for the visible reisomerization and did not affect the LCST of the polymer. This led to the realization of a logic "NOT A" for…
