Corticospinal and strength adaptations following unilateral strength training after stroke
Creators: name: Ledwell, Noah Michael Huntington
Publisher: name: University of British Columbia
Year: 2016

description: Unilateral strength training of the less affected (LA) limb has been shown to improve strength bilaterally. This improved strength is referred to as cross-education in the literature. This intervention has the potential to be beneficial for individuals who cannot train both sides of the body due to post-stroke hemiparesis. To date only one group has researched cross-education in the upper limb in stroke, with varied results. The main purpose of our work was to determine if strength training of the LA forearm would change patterns of cortical excitability bilaterally after stroke, and additionally affect changes in strength and function bilaterally. Twenty-four participants with chronic (> 6 months) stroke-related hemiparesis engaged in three baseline sessions separated by 4-7 days. During these sessions individuals’ forearm strength, motor function, and motor impairment were tested, along with a TMS based assessment of corticospinal excitability and intracortical circuits. On a fourth visit participants completed their first training session using the LA arm, then were given the same wrist extension strength-training device to take home. Participants completed three 25-minute training sessions, weekly; one in the laboratory and the remaining two at home. After 5 weeks of training, participants returned to the laboratory for post-intervention retention tests. Cross-education increased strength in the LA wrist extensors (p = 0.026) and the untrained, more-affected (MA) wrist extensors (p = 0.05) in participants with chronic stroke, at the 1-week retention test. Further, LA arm strength remained increased at 5-week retention test (p = 0.023) despite there being no further training. There were strength improvements in the majority of participants in both their trained (17 of 24) and untrained (12 of 24) wrist extensors. There was a decrease in corticospinal inhibition in the LA hemisphere, and a release of interhemispheric inhibition (IHI) bilaterally. A significant increases in motor function and a decrease in motor impairment was seen, respectively. Results indicate that cross-education could be a valuable tool for increasing strength in chronic stroke. Cross-education training of the LA upper limb may allow individuals who do not have adequate function in their MA limb prior to training engage in rehabilitative interventions post-training.

description: In this paper we study controlled Piecewise Deterministic Markov Processes with finite time horizon and unbounded rewards. Using an embedding procedure we reduce these problems to discrete-time Markov Decision Processes. Under some continuity and compactness conditions we establish the existence of an optimal policy and show that the value function is the unique solution of the Bellman equation. It is remarkable that this statement is true for unbounded rewards and without any contraction assumptions. Further conditions imply the existence of optimal nonrelaxed controls. We highlight our findings by two examples from financial mathematics.

Dark Matter attempts for CoGeNT and DAMA

description: Recently, the CoGeNT collaboration presented a positive signal for an annual modulation in their data set. In light of the long standing annual modulation signal in DAMA/LIBRA, we analyze the compatibility of both of these signal within the hypothesis of dark matter (DM) scattering on nuclei, taking into account existing experimental constraints. We consider the cases of elastic and inelastic scattering with either spin-dependent or spin-independent coupling to nucleons. We allow for isospin violating interactions as well as for light mediators. We find that there is some tension between the size of the modulation signal and the time-integrated event excess in CoGeNT, making it difficult to explain both simultaneously. Moreover, within the wide range of DM interaction models considered, we do not find a simultaneous explanation of CoGeNT and DAMA/LIBRA compatible with constraints from other experiments. However, in certain cases part of the data can be made consistent. For example, the modulation signal from CoGeNT becomes consistent with the total rate and with limits from other DM searches at 90% CL (but not with the DAMA/LIBRA signal) if DM scattering is inelastic spin-independent with just the right couplings to protons and neutrons to reduce the scattering rate on xenon. Conversely the DAMA/LIBRA signal (but not CoGeNT) can be explained by spin-dependent inelastic DM scattering.

description: The young open cluster Collinder 419 surrounds the massive O star, HD 193322, that is itself a remarkable multiple star system containing at least four components. Here we present a discussion of the cluster distance based upon new spectral classifications of the brighter members, UBV photometry, and an analysis of astrometric and photometric data from the UCAC3 and 2MASS catalogs. We determine an average cluster reddening of E(B-V)=0.37 +- 0.05 mag and a cluster distance of 741 +- 36 pc. The cluster probably contains some very young stars that may include a reddened M3 III star, IRAS~20161+4035.

description: For an environmentally sustainable future, electric vehicle (EV) adoption rates have been growing exponentially around the world. There is a pressing need for constructing smart charging infrastructures that can successfully integrate the large influx of connected and autonomous EVs (CAEVs) into the smart grids. To fulfill the aspiration of massive deployment of autonomous mobility on demand (AMoD) services, the proposed fast and secure framework will need to address the long charging times and long waiting times of static charging. It will also need to consider dynamic wireless charging as a viable solution for the CAEVs on the move. In this thesis, a novel three-layer charging system design of static and dynamic wireless charging that can operate with the existing wired charging infrastructure and standards for Intelligent Transportation System (ITS) is presented. This internet of things (IoT) application is accompanied by a proposed handshake protocol with light-weight request message frames. It employs vehicle to infrastructure (V2I) and vehicle to grid (V2G) communications for fulfilling charging requests of CAEVs with the shortest possible route to the destination. The charging requests of the CAEV users are fulfilled by dynamically distributing the request over the three different types of charging equipment. Further, the requests are serviced and billed privately and securely using two different proposed payment schemes with the encrypted virtual currency. The hardware independent system can detect misalignment of the CAEVs on the wireless charging pads and the speed issue errors in dynamic wireless charging systems as well as avoid free-riders. Additionally, the proposed dynamic wireless charging network (DWCN) design specification tool is analyzed. The suggestions made by the tool for building a DWCN can enable implementers to achieve the desired charging delivery performance at the lowest cost possible. Finally, the presented system is simulated, and this verified and validated simulator is revealed to make reservations and plan trips with minimum waiting times, travel costs, and battery consumption per vehicle trip. The system results proved 90.25% charge delivery efficiency. This system is then compared with alternative system designs to help showcase its ability to aid implementers and analysts in making design choices with the simulation.

description: We investigate the phase difference of the sunspot cycles in the two hemispheres and compare it with the latitudinal sunspot distribution. If the north-south phase difference exhibits a long-term tendency, it should not be regarded as a stochastic phenomenon. We use datasets of historical sunspot records and drawings made by Staudacher, Hamilton, Gimingham, Carrington, Spouml;rer, and Greenwich observers, as well as the sunspot activity during the Maunder minimum reconstructed by Ribes and Nesme-Ribes. We employ cross-recurrence plots to analyse north-south phase differences. We show that during the last 300 years, the persistence of phase-leading in one of the hemispheres exhibits a secular variation. Changes from one hemisphere to the other leading in phase were registered near 1928 and 1968 as well as two historical ones near 1783 and 1875. A long-term anticorrelation between the hemispheric phase differences in the sunspot cycles and the latitudinal distribution of sunspots was traced since 1750.

A Tailored Viro-Immunotherapy Combination Approach for the Treatment of BRCA1/2 Mutated Breast and Ovarian Cancers

description: Hereditary breast and ovarian cancers (HBOC) represent 5-10% of breast and 10-15% of ovarian cancer cases. These cancers tend to be aggressive and curative treatment strategies are scarce. Poly(ADP-ribose) polymerase inhibitors (PARPi), a family of drugs that inhibit DNA repair, are a promising therapy for cancers harbouring mutations in their DNA repair machinery, such as HBOC. Unfortunately, nearly all patients ultimately become resistant to PARPi, leaving limited options for definitive treatment. Oncolytic or “cancer-killing” viruses are an innovative immunotherapeutic platform capable of selectively targeting cancer cells, leaving healthy tissues unharmed. Our group has demonstrated that oncolytic rhabdoviruses may be used to deliver therapeutic payloads by encoding targeting sequences to act on genes via RNA interference. In the present work, I have engineered the oncolytic virus, vesicular stomatitis virus (VSV), to express a variety of microRNA (miRNA) sequences that target genes essential for DNA repair, sensitizing resistant cancer cells to PARPi therapy. After initial experiments revealed hurdles concerning the functionality of artificial miRNAs which specifically target BRCA1 and BRCA2 I encoded the naturally occurring hsa-miR-182 into VSV to knockdown BRCA1 and additional genes essential for DNA repair. Using a 3D spheroid model, I have demonstrated sensitization of initially resistant MDA-MB-231 breast cancer cells to the PARPi, rucaparib. Complementary work exploring the shuttling of miRNAs into small extracellular vesicles, or EVs, has also shown that we can take advantage of the EV packaging facilities in infected cells, inducing the packaging of miRNAs over-expressed by VSV (EV-miRNAs) into EVs. Future work will address the functionality of these EV-miRNAs, testing their ability to knockdown targets in uninfected cancer cells.

description: A class of chalcogenide alloy materials that shows significant changes in optical properties upon an amorphous-to-crystalline phase transition has lead to development of large data capacities in modern optical data storage. Among chalcogenide phase-change materials, Ge2Sb2Te5 (GST) is most widely used because of its reliability. We use a pair of femtosecond light pulses to demonstrate the ultrafast optical manipulation of atomic arrangements from tetrahedral (amorphous) to octahedral (crystalline) Ge-coordination in GST superlattices. Depending on the parameters of the second pump-pulse, ultrafast nonthermal phase-change occurred within only few-cycles (~ 1 ps) of the coherent motion corresponding to a GeTe4 local vibration. Using the ultrafast switch in chalcogenide alloy memory could lead to a major paradigm shift in memory devices beyond the current generation of silicon-based flash-memory.

Pharmacokinetics, biodistribution and intratumoral distribution of Celludo nanoparticles
Creators: name: Zhao, Yucheng
Publisher: name: University of British Columbia
Year: 2017

description: Anti-tubulin agents are the most potent and broadest spectrum drugs for cancer therapy, including taxanes and vinca alkaloids. However, there are two major limitations for their clinical use: multidrug resistance (MDR), and significant side effects such as neutropenia and neuropathy. The overexpression of P-glycoprotein (Pgp) is the most commonly found mechanism for MDR in cancer. Our lab has screened several anti-tubulin agents against different MDR tumor cells. The results show that podophyllotoxin (PPT) remained highly active against the resistant cell lines with an IC50 of ~10 nM. However, PPT is insoluble and exhibits significant side effects due to poor selectivity. A nanoparticle dosage form of PPT was developed by covalently conjugating PPT and polyethylene glycol (PEG) to acetylated carboxymethyl cellulose (CMC-Ac) via ester linkages. The optimized polymer conjugates self-assembled into 20 nm particles (named Celludo) and displayed significantly improved efficacy against MDR tumors in mice compared to free PPT and the standard taxane chemotherapies. My thesis focused on developing a robust and reproducible HPLC method to measure PPT concentrations in biological samples in order to compare the pharmacokinetics (PK) and biodistribution (BD) of Celludo and free PPT. The kinetics of intratumoral distribution of the Celludo nanoparticles was also examined. Compared to free PPT, Celludo displayed extended blood circulation with 18-fold prolonged half-life, 9,000- fold higher area under the curve (AUC), and 1,000-fold reduced clearance compared to free PPT. The tumor uptake of Celludo was 500-fold higher than that of free PPT. With Celludo, the overall delivery to the tumor was 4.5-, 3.8-. 3.4-and 1.2- fold higher than that delivered to the liver, lung, heart, and spleen respectively. At 6 h, Celludo nanoparticles accumulated equally in the hypervascular and hypovascular region within the tumor. One and two days post-injection, the amount of Celludo in the hypervascular region remained the same, while the penetration to the hypovascular area increased constantly over 48 h post-injection. The data suggest that Celludo was an effective system targeting PPT to the tumor with enhanced penetration to the tumor core.

description: We present the methodology for, and the first results from, a new imaging program aimed at identifying and characterizing the host galaxies of damped Lyman-alpha absorbers (DLAs) at z>2. We target quasar sightlines with multiple optically-thick HI absorbers and use the higher-redshift system as a "blocking filter" (via its Lyman-limit absorption) to eliminate all far-ultraviolet (FUV) emission from the quasar. This allows us to directly image the rest-frame FUV continuum emission of the lower-redshift DLA, without any quasar contamination and with no bias towards large impact parameters. We introduce a formalism based on galaxy number counts and Bayesian statistics with which we quantify the probability that a candidate is the DLA host galaxy. This method will allow the identification of a bona fide sample of DLAs that are too faint to be spectroscopically confirmed. The same formalism can be adopted to the study of other quasar absorption line systems (e.g. MgII absorbers). We have applied this imaging technique to two QSO sightlines. For the z~2.69 DLA towards J073149+285449, a galaxy with impact parameter b=1.54"=11.89 kpc and implied star formation rate (SFR) of ~5 M/yr is identified as the most reliable candidate. In the case of the z~2.92 DLA towards J211444-005533, no likely host is found down to a 3-sigma SFR limit of 1.4 M/yr. Studying the HI column density as a function of the impact parameter, including 6 DLAs with known hosts from the literature, we find evidence that the observed HI distribution is more extended than what is generally predicted from numerical simulation.

The roles of SH2-containing inositol 5'-phosphatase 1 (SHIP1) and signal transducer and activator of transcription 3 (STAT3) in interleukin-10 regulation of activated macrophages
Creators: name: Tsz Ying Sylvia, Cheung
Publisher: name: University of British Columbia

description: Inflammation is a protective mechanism against infection, but it must be appropriately regulated to prevent pathological consequences including inflammatory diseases. Interleukin-10 (IL-10) is a key anti-inflammatory cytokine that inhibits the activation of many immune cell types, including the macrophage, to prevent exaggerated immune responses. Understanding the signalling pathway downstream of IL-10 and IL-10 receptor (IL-10R) is essential in developing therapeutics to treat inflammatory diseases. Canonically, IL-10R signalling is described as solely depending on the activation of the transcription factor STAT3 and the expression of STAT3-response genes. However, our laboratory has previously shown that IL-10 also activates the inositol 5'-phosphatase SHIP1 to mediate its anti-inflammatory responses, such as inhibiting the expression of pro-inflammatory cytokines. Moreover, we have now found that IL-10 is able to inhibit expression of miRNA-155 (miR-155) in macrophages activated by the bacterial product lipopolysaccharide (LPS). This inhibition by IL-10 requires both STAT3 and SHIP1, and occurs at the maturation step, but not at the transcription step, of miR-155. Consistent with SHIP1’s involvement in IL-10 function, a previously described SHIP1 activator, AQX-MN100, mimics IL-10 and inhibits LPS-induced miR-155. Next, we investigated the roles of STAT3 and SHIP1 in IL-10 regulation of global gene expression in activated macrophages. Among the genes identified as IL-10 regulated, we have found different subsets of genes potentially to be SHIP1-regulated, STAT3-regulated, and SHIP1-STAT3 regulated. Considering the importance of SHIP1 activation in IL-10 function, SHIP1 activators provide an alternate way to control inflammation. We have previously shown that SHIP1 activators bind to SHIP1’s C2 domain and regulate SHIP1 enzymatic activity allosterically. Using x-ray crystallography, we obtained the crystal structure of SHIP1’s phosphatase and C2 domains, the minimal region necessary for allosteric activation by SHIP1 activators. Analysis of the crystal structure revealed differences between SHIP1 and related phosphatases. Biochemical and biophysical methods have been employed to identify amino acid residues potentially interacting with SHIP1 activators. Together, this work strengthens the model that STAT3 and SHIP1 work together to mediate the anti-inflammatory function of IL-10. We also described the structure of SHIP1, providing the first step in rational drug design to generate better small molecule SHIP1 activators.

description: We measured the trigonometric annual parallax of H$_2$O maser source associated with the massive star-forming regions IRAS 06061+2151 with VERA. The annual parallax of $0.496\pm0.031$ mas corresponding to a distance of $2.02^{+0.13}_{-0.12}$ kpc was obtained by 10 epochs of observations from 2007 October to 2009 September. This distance was obtained with a higher accuracy than the photometric distance previously measured, and places IRAS 06061+2151 in the Perseus spiral arm. We found that IRAS 06061+2151 also has a peculiar motion of larger than 15 km s$^{-1}$ counter to the Galactic rotation. That is similar to five sources in the Perseus spiral arm, whose parallaxes and proper motions have already been measured with higher accuracy. Moreover, these sources move at on average 27 km s$^{-1}$ toward the Galactic center and counter to the Galactic rotation.

description: Clustering, assortativity, and communities are key features of complex networks. We probe dependencies between these attributes and find that ensembles with strong clustering display both high assortativity by degree and prominent community structure, while ensembles with high assortativity are much less biased towards clustering or community structure. Further, clustered networks can amplify small homophilic bias for trait assortativity. This marked asymmetry suggests that transitivity, rather than homophily, drives the standard nonsocial/social network dichotomy.

Jet-hadron correlations in STAR

description: Advancements in full jet reconstruction have made it possible to use jets as triggers in azimuthal angular correlations to study the modification of hard-scattered partons in the medium created in ultrarelativistic heavy-ion collisions. This increases the range of parton energies accessible in these analyses and improves the signal-to-background ratio compared to dihadron correlations. Results of a systematic study of jet-hadron correlations in central Au-Au collisions at sqrt(s_NN) = 200 GeV are indicative of a broadening and softening of jets which interact with the medium. Furthermore, jet-hadron correlations suggest that the suppression of the associated hadron yield at high-pT is balanced in large part by low-pT enhancement.

description: We investigate the effect of electrostatic screening on a nanoscale silicon MOSFET electrometer. We find that screening by the lightly doped p-type substrate, on which the MOSFET is fabricated, significantly affects the sensitivity of the device. We are able to tune the rate and magnitude of the screening effect by varying the temperature and the voltages applied to the device, respectively. We show that despite this screening effect, the electrometer is still very sensitive to its electrostatic environment, even at room temperature.

 Executive Summary
 This deliverable is the output of task 5.2 Understanding the challenges for
 distributed computational analysis across Europe. The task activities started
 defining a set of aspects for which the project would like to investigate their status
 in existing workflow and orchestrator systems. These aspects relate to the
 distribution of data and computation, to the support to sensitive data, and to the
 support for data provenance and reproducibility. In addition to questions related to
 these topics, other generic questions were put all together. An initial classification
 of workflow environments and orchestrators was also done, and from there the task
 searched for information about the different systems. The information was
 provided in some cases by project partners, in other cases by system owners and in
 other cases fetched by partners from websites or other sources of information.
 From this initial catalogue, the partners involved in this activity selected the most
 promising ones that were invited to present in two workshops. The workshops were
 online and organized quite informally, but enabled a lot of discussion and provided
 in-depth information on the topics more relevant to the project.
 The information collected in the two phases of the task (catalogue elaboration and
 workshops) is summarized and analysed in this deliverable.
Effects of the galactic magnetic field upon large scale anisotropies of extragalactic Cosmic Rays

description: The large scale pattern in the arrival directions of extragalactic cosmic rays that reach the Earth is different from that of the flux arriving to the halo of the Galaxy as a result of the propagation through the galactic magnetic field. Two different effects are relevant in this process: deflections of trajectories and (de)acceleration by the electric field component due to the galactic rotation. The deflection of the cosmic ray trajectories makes the flux intensity arriving to the halo from some direction to appear reaching the Earth from another direction. This applies to any intrinsic anisotropy in the extragalactic distribution or, even in the absence of intrinsic anisotropies, to the dipolar Compton-Getting anisotropy induced when the observer is moving with respect to the cosmic rays rest frame. For an observer moving with the solar system, cosmic rays traveling through far away regions of the Galaxy also experience an electric force coming from the relative motion (due to the rotation of the Galaxy) of the local system in which the field can be considered as being purely magnetic. This produces small changes in the particles momentum that can originate large scale anisotropies even for an isotropic extragalactic flux.

description: We present J-band long-slit spectroscopic observation of NGC 1068 classified as a Seyfert 2 galaxy. J-band observations with OAO/ISLE provide clear detection of spatially extended [Fe II]1.257um and [P II]1.188um lines. We found that [Fe II]1.257um/[P II]1.188um increases with distance from a central continuum peak. Observed line ratios around the nucleus (continuum peak) are consistent with a typical value expected from photoionization models, while the ratios at 3" - 4" (210-280 pc) east and west of the nucleus are slightly higher than this. In the off nucleus region of NGC 1068 we also found a possible association between [Fe II]1.257um/[P II]1.188um and the radio continuum. This suggests a mild contribution of shock ionization induced by a radio jet outside nucleus while photoionization by the central energy source is dominant near the nucleus.

description: The engineering of polymeric scaffolds for tissue regeneration has known a phenomenal growth during the past decades as materials scientists seek to understand cell biology and cell–material behaviour. Statistical methods are being applied to physico-chemical properties of polymeric scaffolds for tissue engineering (TE) to guide through the complexity of experimental conditions. We have attempted using experimental in vitro data and physico-chemical data of electrospun polymeric scaffolds, tested for skin TE, to model scaffold performance using the machine learning (ML) approach. Fibre diameter, pore diameter, water contact angle and Young's modulus were used to find a correlation with MTT assay of L929 fibroblasts cells on the scaffolds after 7 days. Six supervised learning algorithms were trained on the data using Seaborn/Scikit-learn Python libraries. After hyperparameter tuning, random forest regression yielded the highest accuracy of 62.74%. The predictive model was also correlated with in vivo data. This is a first preliminary study on ML methods for the prediction of cell–material interactions on nanofibrous scaffolds.

Holographic two dimensional QCD and Chern-Simons term

description: We present a holographic realization of large Nc massless QCD in two dimensions using a D2/D8 brane construction. The flavor axial anomaly is dual to a three dimensional Chern-Simons term which turns out to be of leading order, and it affects the meson spectrum and holographic renormalization in crucial ways. The massless flavor bosons that exist in the spectrum are found to decouple from the heavier mesons, in agreement with the general lore of non-Abelian bosonization. We also show that an external dynamical photon acquires a mass through the three dimensional Chern-Simons term as expected from the Schwinger mechanism. Massless two dimensional QCD at large Nc exhibits anti-vector-meson dominance due to the axial anomaly.

Critical behavior of the Random-Field Ising Magnet with long range correlated disorder

Year: 2011

description: We study the correlated-disorder driven zero-temperature phase transition of the Random-Field Ising Magnet using exact numerical ground-state calculations for cubic lattices. We consider correlations of the quenched disorder decaying proportional to r^a, where r is the distance between two lattice sites and a<0. To obtain exact ground states, we use a well established mapping to the graph-theoretical maximum-flow problem, which allows us to study large system sizes of more than two million spins. We use finite-size scaling analyses for values a={-1,-2,-3,-7} to calculate the critical point and the critical exponents characterizing the behavior of the specific heat, magnetization, susceptibility and of the correlation length close to the critical point. We find basically the same critical behavior as for the RFIM with delta-correlated disorder, except for the finite-size exponent of the susceptibility and for the case a=-1, where the results are also compatible with a phase transition at infinitesimal disorder strength. A summary of this work can be found at the papercore database at www.papercore.org.

Flaring Active Galactic Nuclei. The cases of 3C 279 and PMN J0948+0022 as seen by the Fermi-LAT

description: Active galactic nuclei (AGNs) exhibit variability across the entire electromagnetic spectrum with distinct flaring episodes at different frequencies. The high sensitivity and nearly uniform sky coverage of the Large Area Telescope on board the Fermi satellite make it a powerful tool for monitoring a large number of AGNs over long timescales. This allowed us to detect several flaring AGNs in gamma rays, triggering dedicated multifrequency campaigns on these sources from radio to TeV energies. We discuss the results for two different types of flaring AGN: the flat spectrum radio quasar 3C 279, in particular the coincidence of a gamma-ray flare from this source with the drastic change of the optical polarization angle, and the first gamma-ray flare from a radio-loud narrow-line Seyfert 1, PMN J0948+0022.

description: Three-body continuum problems are investigated for light nuclei of astrophysical relevance. We focus on three-body decays of resonances or recombination via resonances or the continuum background. The concepts of widths, decay mechanisms and dynamic evolution are discussed. We also discuss results for the triple $α$ decay in connection with $2^+$ resonances and density and temperature dependence rates of recombination into light nuclei from $α$-particles and neutrons.

description: Metal contacts have been identified to be a key technological bottleneck for the realization of viable graphene electronics. Recently, it was observed that for structures that possess both a top and a bottom gate, the electron-hole conductance asymmetry can be modulated by the bottom gate. In this letter, we explain this observation by postulating the presence of an effective thin interfacial dielectric layer between the metal contact and the underlying graphene. Electrical results from quantum transport calculations accounting for this modified electrostatics corroborate well with the experimentally measured contact resistances. Our study indicates that the engineering of metal- graphene interface is a crucial step towards reducing the contact resistance for high performance graphene transistors.

description: Die Mykotoxine Alternariol (AOH) und Alternariol-9-methylether (AME) sind häufig in Lebensmitteln nachgewiesene Alternaria-Toxine. Derzeit gibt es keine gesetzlichen Regelungen für Höchstmengen dieser Toxine, da bislang nur wenige Studien hinsichtlich ihrer Toxizität und Toxikokinetik existieren. In dieser Arbeit wurden daher in vitro-Untersuchungen zur Resorption, zum Metabolismus und zur Mutagenität von AOH und AME durchgeführt, die einen Beitrag zur Risikobewertung leisten sollen.
