Synthesis and structural characterisation of unprecedented primary N -nitrosamines coordinated to iridium(IV)
The redox chemistry of the N-nitrosamine complexes [IrCl5(RN(H)NO)]2- (R = benzyl or n-butyl) was studied in detail. One-electron oxidations at around 200 mV vs. ferrocene/ferrocenium were reversible in cyclic voltammograms. UV-vis spectroelectrochemistry reveals spectra characteristic of IrIV species but also partial decomposition of the oxidised species [IrIVCl5(RN(H)NO)]- on this timescale (minutes). Detailed studies on chemically oxidised solutions of the parent IrIII complexes gave evidence for paramagnetic IrIV from NMR spectra. Final products of the decomposition were the corresponding alcohols and presumably [IrIIICl5(L)]2- (L = N2, solvent, amine) complexes. Similar decomposition reactions of acidic DMSO solutions of [IrCl5(RN(H)NO)]2-revealed that this combination produces the so-called "activated" DMSO (Me2S+-O- or Me2S+-OE, with "E" being an electrophile) which oxidises the parent IrIII complexes. Finally, with the very reactive purple IrIV compound (PPh4)[IrCl5(BnN(H)NO)], the first primary N-nitrosamine coordinated to [IrIVCl5]- was isolated and characterised by UV-vis absorption, FTIR, NMR spectroscopy, ultra-high resolution electrospray mass spectrometry (UHR-ESI-MS) and iridium L3 X-ray absorption near-edge spectroscopy (XANES).Instituto de Investigaciones FisicoquĂmicas TeĂłricas y Aplicada
A low-cost fluorescence reader for in vitro transcription and nucleic acid detection with Cas13a
Point-of-care testing (POCT) in low-resource settings requires tools that can operate independently of typical laboratory infrastructure. Due to its favorable signal-to-background ratio, a wide variety of biomedical tests utilize fluorescence as a readout. However, fluorescence techniques often require expensive or complex instrumentation and can be difficult to adapt for POCT. To address this issue, we developed a pocket-sized fluorescence detector costing less than $15 that is easy to manufacture and can operate in low-resource settings. It is built from standard electronic components, including an LED and a light dependent resistor, filter foils and 3D printed parts, and reliably reaches a lower limit of detection (LOD) of. 6.8 nM fluorescein, which is sufficient to follow typical biochemical reactions used in POCT applications. All assays are conducted on filter paper, which allows for a flat detector architecture to improve signal collection. We validate the device by quantifying in vitro RNA transcription and also demonstrate sequence-specific detection of target RNAs with an LOD of 3.7 nM using a Cas13a-based fluorescence assay. Cas13a is an RNA-guided, RNA-targeting CRISPR effector with promiscuous RNase activity upon recognition of its RNA target. Cas13a sensing is highly specific and adaptable and in combination with our detector represents a promising approach for nucleic acid POCT. Furthermore, our open-source device may be used in educational settings, through providing low cost instrumentation for quantitative assays or as a platform to integrate hardware, software and biochemistry concepts in the future
Outbreak of cryptosporidium hominis following river flooding in the city of Halle (Saale), Germany, August 2013
Background: During weeks 32â33, 2013, 24 cases of cryptosporidiosis were notified in the city of Halle (annual mean 2008â2012: 9 cases). We investigated the outbreak to identify the source and recommend control measures, considering that between weeks 23â25 the river Saale which flows through the city centre overflowed the floodplain, parts of the city centre and damaged sewage systems. Methods: We defined a case as a resident of Halle with gastroenteritis, Cryptosporidium-positive stool and disease onset weeks 27 through 47. In a caseâcontrol study among kindergarten children, we compared cases and controls regarding environmental exposure, use of swimming pools, zoo visits and tap water consumption 14 days pre-onset or a corresponding 14-days-period (controls) and adjusted for residence. Stool specimens were tested by microscopy and PCR, and Cryptosporidium DNA was sequenced. Samples from public water system, swimming pools and river Saale were examined for Cryptosporidium oocysts (microscopy and PCR). Results: Overall, 167 cases were detected, 40/167 (24%) were classified as secondary cases. First disease onsets occurred during week 29, numbers peaked in week 34 and started to decrease in week 36. Median age was 8 years (range: 0â77). Compared to controls (n = 61), cases (n = 20) were more likely to report visits to previously flooded areas (OR:â4.9; 95%-CI:â1.4-18) and the zoo (OR:â2.6; 95%-CI:â0.9-7.6). In multivariable analysis visits to the floodplain remained the sole risk factor (OR:â5.5; 95%-CI:â1.4-22). Only C.hominis of a single genotype (IbA9G2) was detected in stools. Oocysts were detected in samples from the river, two local lakes and three public swimming pools by microscopy, but not in the public water supply. Conclusions: Evidence suggests that activities in the dried out floodplain led to infection among children. Secondary transmissions may be involved. Consequently, authorities recommended to avoid playing, swimming and having picnics in the flood-affected area. Health authorities should consider the potential health risks of long-term surviving parasites persisting on flooded grounds and in open waters even several weeks after the flooding and of bathing places close to sewage spill-overs. Preventive measures comprise water sampling (involving parasites), information of the public and prolonged closures of potentially contaminated sites
Carbon-rich cyclopentadienyl ruthenium allenylidene complexes
Ruthenium allenylidene complexes with carbon-rich polyaromatic moieties have been synthesized by using [RuCl(η5-C5H5)(PPh3)2] (η5-C5H5 = cyclopentadienyl) as a precursor and the propargyl alcohols 10-ethynyl-10-hydroxyanthracen-9-one (ACO), 13-ethynyl-13-hydroxypentacen-6-one (PCO), 1-phenyl-1-(pyren-1-yl)prop-2-yn-1-ol (PyrPh), 9-ethynyl-9H-fluoren-9-ol (FN) and 6-ethynyl-6H-benzo[cd]pyren-6-ol (BPyr) as ligands. The resulting cationic allenylidene complexes, [Ru(η5-C5H5)([double bond, length as m-dash]C[double bond, length as m-dash]C[double bond, length as m-dash](AO))(PPh3)2]PF6 (1), [Ru(η5-C5H5)([double bond, length as m-dash]C[double bond, length as m-dash]C[double bond, length as m-dash](PCO))(PPh3)2]PF6 (2), [Ru(η5-C5H5)([double bond, length as m-dash]C[double bond, length as m-dash]C[double bond, length as m-dash](PyrPh))(PPh3)2]PF6 (3), [Ru(η5-C5H5)([double bond, length as m-dash]C[double bond, length as m-dash]C[double bond, length as m-dash](FN))(PPh3)2]PF6 (4), and [Ru(η5-C5H5)([double bond, length as m-dash]C[double bond, length as m-dash]C[double bond, length as m-dash](BPyr))(PPh3)2]PF6 (5) show interesting intermolecular Ï-interactions in the solid-state structure as well as solution state complexation with pyrene (documented by Job's plots experiments). CV data indicate possible Ru(II)/Ru(III) oxidation, as well as the potential reduction of the carbon-rich allenylidene moiety
Stimulated resonant inelastic X-ray scattering in a solid
When materials are exposed to X-ray pulses with sufficiently high intensity, various nonlinear effects can occur. The most fundamental one consists of stimulated electronic decays after resonant absorption of X-rays. Such stimulated decays enhance the number of emitted photons and the emission direction is confined to that of the stimulating incident photons which clone themselves in the process. Here we report the observation of stimulated resonant elastic (REXS) and inelastic (RIXS) X-ray scattering near the cobalt L3 edge in solid Co/Pd multilayer samples. We observe an enhancement of order 106 of the stimulated over the conventional spontaneous RIXS signal into the small acceptance angle of the RIXS spectrometer. We also find that in solids both stimulated REXS and RIXS spectra contain contributions from inelastic electron scattering processes, even for ultrashort 5 fs pulses. Our results reveal the potential and caveats of the development of stimulated RIXS in condensed matter

Applying Mixed Reality to Support Motor Learning
In diesem Beitrag stellen wir vier Einsatzmöglichkeiten von Mixed Reality (MR) zur UnterstĂŒtzung von motorischem Lernen vor. Wir haben Kinaesthetics-Kurse im Kontext Pflege hospitiert und Interviews mit Kinaesthetics-DozentInnen und -Auszubildenden durchgefĂŒhrt. Die erhobenen Daten wurden mit Fokus auf den Ablauf des Lernprozesses und bestehende Probleme analysiert. Auf Basis der kontextuellen Analyse wurden Anforderungen an technische Systeme, welche motorisches Lernen unterstĂŒtzen sollen, identifiziert. In Bezug zu den erarbeiteten Anforderungen und bestehender Literatur werden von uns vier Möglichkeiten vorgestellt, um MR fĂŒr die UnterstĂŒtzung von motorischem Lernen einzusetzen.publishe
InformationSense : Trade-offs for the Design and the Implementation of a Large Highly Deformable Cloth Display
Deformable displays can provide two major benefits compared to rigid displays: Objects of different shapes and deformabilities, situated in our physical environment, can be equipped with deformable displays, and users can benefit from their pre-existing knowledge about the interaction with physical objects when interacting with deformable displays. In this article we present InformationSense, a large, highly deformable cloth display. The article contributes to two research areas in the context of deformable displays: It presents an approach for the tracking of large, highly deformable surfaces, and it presents one of the first UX analyses of cloth displays that will help with the design of future interaction techniques for this kind of display. The comparison of InformationSense with a rigid display interface unveiled the trade-off that while users are able to interact with InformationSense more naturally and significantly preferred InformationSense in terms of joy of use, they preferred the rigid display interfaces in terms of efficiency. This suggests that deformable displays are already suitable if high hedonic qualities are important but need to be enhanced with additional digital power if high pragmatic qualities are required.publishe
HCI meets Nursing Care : The application of Mixed Reality in basic Nursing Care Education
The traditional education of basic activities in nursing care (e.g. patient mobilization or hygiene) poses different limitations like, e.g. restricted options for self-education or limited realism in the learning context. By blending the real-world with virtual content, Mixed Reality (MR) technology holds great potential to address given shortcomings in interactive learning scenarios. In this work we explore how Human-Computer Interaction (HCI) can inform the development of MR systems for basic nursing care education. We conducted a review of the current employment of MR and Virtual Reality (VR) displays (including desktop-based ones) in basic nursing care education and discuss our results in respect to the conceptual HCI framework Blended Interaction. In contrast to existing reviews, our work differs by placing a clear focus on activities of basic nursing care education and the question how HCI can inspire the design of MR applications which support such activities. We first conducted a search of the Web of Science Core Collection based on predefined search terms. 139 publications were found. We filtered them by inclusion criteria to ensure that only papers which use MR or VR displays to support basic nursing care education remained. The remaining publications were viewed with respect to the four domains of design provided by the Blended Interaction framework, namely (1) individual interaction, (2) social interaction and communication, (3) workflow and (4) physical environment. Our results indicate that MR in basic nursing care education just barely scratches the surface. The majority of systems employs desktop-based VR. Most systems facilitate individual interactions by mouse, keyboard or specific haptic devices, support limited or no social interactions, provide structured workflows or free interactions, and employ 2-dimensional VR displays to simulate work environments. Future MR systems could allow for more realistic interactions, stimulate collaboration through 3-dimensional real-world overlays, enhance learning workflows by rendering or deliberately hiding information within real-world scenarios, and facilitate immersive environments with physically enabled virtual objects. In conclusion, we show that the present use of MR in basic nursing care education is limited and introduce directions for design which can help leveraging the technologiesâ full potential in the future.publishe
