description: We investigate the infrared (IR) properties of cool, evolved stars in the Small Magellanic Cloud (SMC), including the red giant branch (RGB) stars and the dust-producing red supergiant (RSG) and asymptotic giant branch (AGB) stars using observations from the Spitzer Space Telescope Legacy program entitled: "Surveying the Agents of Galaxy Evolution in the Tidally-stripped, Low Metallicity SMC", or SAGE-SMC. The survey includes, for the first time, full spatial coverage of the SMC bar, wing, and tail regions at infrared (IR) wavelengths (3.6 - 160 microns). We identify evolved stars using a combination of near-IR and mid-IR photometry and point out a new feature in the mid-IR color-magnitude diagram that may be due to particularly dusty O-rich AGB stars. We find that the RSG and AGB stars each contribute ~20% of the global SMC flux (extended + point-source) at 3.6 microns, which emphasizes the importance of both stellar types to the integrated flux of distant metal-poor galaxies. The equivalent SAGE survey of the higher-metallicity Large Magellanic Cloud (SAGE-LMC) allows us to explore the influence of metallicity on dust production. We find that the SMC RSG stars are less likely to produce a large amount of dust (as indicated by the [3.6]-[8] color). There is a higher fraction of carbon-rich stars in the SMC, and these stars appear to able to reach colors as red as their LMC counterparts, indicating that C-rich dust forms efficiently in both galaxies. A preliminary estimate of the dust production in AGB and RSG stars reveals that the extreme C-rich AGB stars dominate the dust input in both galaxies, and that the O-rich stars may play a larger role in the LMC than in the SMC.

description: X-ray appearance of normal galaxies is mainly determined by X-ray binaries powered by accretion onto a neutron star or a stellar mass black hole. Their populations scale with the star-formation rate and stellar mass of the host galaxy and their X-ray luminosity distributions show a significant split between star-forming and passive galaxies, both facts being consequences of the dichotomy between high- and low-mass X-ray binaries. Metallicity, IMF and stellar age dependencies, and dynamical formation channels add complexity to this picture. The numbers of high-mass X-ray binaries observed in star-forming galaxies indicate quite high probability for a massive star to become an accretion powered X-ray source once upon its lifetime. This explains the unexpectedly high contribution of X-ray binaries to the Cosmic X-ray Background, of the order of $\sim 10\%$, mostly via X-ray emission of faint star-forming galaxies located at moderate redshifts which may account for the unresolved part of the CXB. Cosmological evolution of the $L_X-{\rm SFR}$ relation can make high-mass X-ray binaries a potentially significant factor in (pre)heating of intergalactic medium in the early Universe.

description: We illustrate the structure and the main phenomenological features of a supersymmetric model (the USSM-A) built following a bottom-up approach and containing an anomalous abelian gauge symmetry. This model supports a gauged axion in its spectrum and provides a generalization of the global (supersymmetric) Peccei-Quinn construction. Complete simulations of the neutralino relic density are performed. Bounds from CAST and WMAP, combined with dark matter simulations, provide significant constraints on the scale of the interactions between the axion and the gauge fields.

description: We have combined multi-epoch images from the Infrared Side Port Imager on the CTIO 4-meter telescope to derive a 3-sigma limit of J=21.7 for the ultra cool brown dwarf companion to WD 0806-661 (GJ 3483). We find that J-[4.5]>4.95, redder than any other brown dwarf known to date. With theoretical evolutionary models and ages 1.5-2.7 Gyr, we estimate the brown dwarf companion to have mass <10-13 Jupiter masses and temperature <400 K, providing evidence that this is among the coolest brown dwarfs currently known. The range of masses for this object is consistent with that anticipated from Jeans-mass fragmentation and we present this as the likely formation mechanism. However, we find that substellar companions of similar mass (~7-17 Jupiter masses) are distributed over a wide range of semi-major axes, which suggests that giant planet and low-mass brown dwarf formation overlap in this mass range.

Economic, environmental and social optimization of forest-based biomass supply chains for bioenergy and biofuels
Creators: name: Cambero Calva, Claudia Adrileth
Publisher: name: University of British Columbia
Year: 2016

description: Utilization of forest-based biomass for bioenergy and biofuels production could generate additional revenue streams, reduce greenhouse gas (GHG) emissions and generate development opportunities for forest-dependent communities. Barriers such as the capital intensity of conversion technologies, complexity of biomass procurement logistics, and the need to establish sustainable supply chains must be overcome. Mathematical modeling has supported the optimal design of biomass supply chains for bioenergy or biofuels production separately, mostly from an economic perspective. Some studies incorporated environmental and/or social criteria in the optimal supply chain design. However, no study modeled forest-based biomass supply chains for the simultaneous bioenergy and biofuels production, considering economic, environmental and social benefits. The development of such model is the objective of this thesis. First, an optimization model is developed that determines the optimal network design and the optimal yearly flows of raw materials and products that maximize the net present value (NPV) of the supply chain. The model considers the flow of energy among co-located conversion technologies and is applied to a case study in Canada. Second, a life cycle environmental analysis is developed to analyze the environmental impacts of the supply chain alternatives in the case study. Third, the optimization model is reformulated as bi-objective with an environmental objective that maximizes the GHG emission savings associated with the supply chain. These savings are estimated by comparing the emissions of the forest-based biomass supply chain system, versus those of the baseline system where unused biomass is disposed with current methods and energy demands are satisfied with currently available sources. Finally, a multi-objective optimization model is generated that integrates a social objective. The social objective is quantified by a social benefit indicator that assigns different levels of impact of job creation based on the type and location of the jobs. The bi-objective and multi-objective optimization models are applied to the case study and solved using a Pareto-generating solution method. Results indicate a trade-off between the NPV of the supply chain and the other two objectives, and a positive correlation between the generation of high impact jobs in the region, and the overall GHG emission savings.

description: Context For patients with borderline resectable pancreatic cancer, the benefit of neoadjuvant therapy remains to be defined. Objective We did a systematic search of the literature on this topic. Methods Prospective studies where chemotherapy with or without radiotherapy was given before surgery to patients with borderline resectable cancer, were analyzed by a meta-analytical approach. Main outcome measures Primary outcome was surgical exploration and resection rates; tumor response, therapy-induced toxicity, and survival were secondary outcomes. Data were expressed as weighted pooled proportions with 95% confidence intervals (95% CI). Results Ten studies with 182 participants were included. Following treatment, 69% of patients (95% CI: 56-80%) were brought to surgery and 80% (95% CI: 66-90%) of surgically-explored patients were resected. Eighty-three percent (95% CI: 74-90%) of resected specimens were deemed R0 resections. The weighted fractions of resected patients alive at 1 and 2 years were 61% (95% CI: 48-100%) and 44% (95% CI: 32-59%), respectively. At restaging following neoadjuvant therapy, weighted frequencies for complete/partial response were 16% (95% CI: 9-28%), 69% (95% CI: 60-76%) for stable disease, and 19% (95% CI: 13-25%) for progressive cancer. Treatment-related grade 3-4 toxicity was 32% (95% CI: 21-45%). Conclusion This meta-analysis shows that downstaging of the lesion following neoadjuvant therapies is uncommon for patients with borderline resectable pancreatic cancer. A clear benefit of this regimen could be to spare surgery to patients with progressive disease during the frame-time chemo-radiotherapy is being delivered.

description: Context While perioperative mortality after pancreaticoduodenectomy is decreasing, key factors remain to be elucidated. Objective The purpose of this study was to investigate inpatient mortality after pancreaticoduodenectomy in the Nationwide Inpatient Sample (NIS), a representative inpatient database in the USA. Methods Patient discharge data (diagnostic and procedure codes) and hospital characteristics were investigated for years 2009 and 2010. The inclusion criteria were a procedure code for pancreaticoduodenectomy, elective procedure, and a pancreatic or peripancreatic cancer diagnosis. Chi-square test determined statistical significance. A logistic regression model for mortality was created from significant variables. Results Two-thousand and 958 patients were identified with an average age of 65±12 years; 53% were male. The mean length of stay was 15±12 days with a mortality of 4% and a complication rate of 57%. Eighty-six percent of pancreaticoduodenectomy occurred in teaching hospitals. Pancreaticoduodenectomy performed in teaching hospitals in the first half of the academic year were associated with higher mortality than in the latter half (5.5% vs. 3.4%, P=0.005). On logistic regression analysis, non-surgical complications are the largest predictor of death (P<0.001) while operations in the latter half of the academic year are associated with decreased mortality (P<0.01). Conclusions The timing of pancreaticoduodenectomy for cancer remained more predictive of mortality than age or length of stay; only complications were more predictive of death than time of year. This suggests that there remains a clinically and statistically significant learning curve for trainees in identifying complications; further study is needed to prove that identification of complications leads to a decrease in mortality rate by taking corrective actions.

description: We present a combined study based on experimental measurements of infrared (IR) dielectric function and first-principles calculations of IR spectra and vibrational density of states (VDOS) of amorphous alumina (am-Al$_2$O$_3$). In particular, we show that the main features of the imaginary part of the dielectric function $ε_2(ω)$ at $\sim$380 and 630 cm$^{-1}$ are related to the motions of threefold coordinated oxygen atoms, which are the vast majority of oxygen atoms in am-Al$_2$O$_3$. Our analysis provides an alternative point of view with respect to an earlier suggested assignment of the vibrational modes, which relates them to the stretching and bending vibrational modes of AlO$_{n}$ ($n=$ 4, 5, and 6) polyhedra. Our assignment is based on the additive decomposition of the VDOS and $ε_2(ω)$ spectra, which shows that: (i) the band at $\sim$380 cm$^{-1}$ features oxygen motions occurring in a direction normal to the plane defined by the three nearest-neighbor aluminum atoms, i.e. out-of-plane motions of oxygen atoms; (ii) Al--O stretching vibrations (i.e. in-plane motions of oxygen atoms) appear at frequencies above $\sim$500 cm$^{-1}$, which characterize the vibrational modes underlying the band at $\sim$630 cm$^{-1}$. Aluminum and fourfold coordinated oxygen atoms contribute uniformly to the VDOS and $ε_2(ω)$ spectra in the frequency region $\sim$350--650 cm$^{-1}$ without causing specific features. Our numerical results are in good agreement with the previous and presently obtained experimental data on the IR dielectric function of am-Al$_2$O$_3$ films. Finally, we show that the IR spectrum can be modeled by assuming isotropic Born charges for aluminum atoms and fourfold coordinated oxygen atoms, while requiring the use of three parameters, defined in a local reference frame, for the anisotropic Born charges of threefold coordinated oxygen atoms.

description: We investigate the fine structure of magnetic fields in the atmosphere of the quiet Sun. We use photospheric magnetic field measurements from {\sc Sunrise}/IMaX with unprecedented spatial resolution to extrapolate the photospheric magnetic field into higher layers of the solar atmosphere with the help of potential and force-free extrapolation techniques. We find that most magnetic loops which reach into the chromosphere or higher have one foot point in relatively strong magnetic field regions in the photosphere. $91%$ of the magnetic energy in the mid chromosphere (at a height of 1 Mm) is in field lines, whose stronger foot point has a strength of more than 300 G, i.e. above the equipartition field strength with convection. The loops reaching into the chromosphere and corona are also found to be asymmetric in the sense that the weaker foot point has a strength $B < 300$ G and is located in the internetwork. Such loops are expected to be strongly dynamic and have short lifetimes, as dictated by the properties of the internetwork fields.

description: We study the radiative heat transfer between a spheroidal metallic nanoparticle and a planar metallic sample for near- and far-field distances. In particular, we investigate the shape dependence of the heat transfer in the near-field regime. In comparison with spherical particles, the heat transfer typically varies by factors between 1/2 and 2 when the particle is deformed such that its volume is kept constant. These estimates help to quantify the deviation of the actual heat transfer recorded by a near-field scanning thermal microscope from the value provided by a dipole model which assumes a perfectly spherical sensor.

Regulation of stomatal morphogenesis and lateral root development in Arabidopsis thaliana by the leucine-rich repeat receptor-like kinase MUSTACHES
Creators: name: Keerthisinghe, Sandra Roshini
Publisher: name: University of British Columbia
Year: 2017

description: Shoot and root systems have evolved numerous specialized structures, including stomata and lateral roots. Stomata, which are essential for mediating gas exchange across the shoot epidermis during photosynthesis, consist of two bilaterally symmetrical guard cells arranged around an epidermal pore. The symmetry displayed by mature stomata is essential for stomatal function. Stomata develop via a dedicated pathway defined by two key divisions, an asymmetric division, and a symmetric division which initiates stomatal bilateral symmetry. The symmetric division is followed by pore and guard cell morphogenesis, which maintains the previously established bilateral symmetry. Lateral roots increase the ability of root systems to acquire nutrients and water from the surrounding environment and lateral root development is also dependent on stage specific divisions. Interestingly, several genes regulating symmetric divisions have also been shown to function in lateral root development. The Leucine-Rich Repeat Receptor-Like Kinase, MUSTACHES (MUS), which belongs to a family of four closely related MUS-LIKE kinases (MUSLs), is required to enforce bilateral symmetry post-symmetric division. Mutants in mus display pore and guard cell morphogenesis defects, as well as defects in microtubule array organization and the polarity of microtubule movement. MUS is expressed in both stomatal lineage and root epidermal cells, suggesting that MUS also functions outside stomatal development. Thus, MUS represents an ideal candidate through which mechanisms influencing pore and guard cell morphogenesis, as well as the impact of post-symmetric division stomatal genes on lateral root development, may be explored. Mutant analysis and time-lapse studies demonstrated that MUS enforces bilateral symmetry by ensuring symmetrical positioning of microtubule organizing centres post-symmetric division. Time lapse studies indicated that microtubule organizing centre delocalization occurred before, and is likely responsible for, the subsequently occurring alterations in microtubule polarity and guard cell morphogenesis defects observed in mus. As well, this work revealed that MUS, the cytoplasmic kinase NIMA-RELATED KINASE 6 and the microtubule associated protein CLIP-170 ASSOCIATED PROTEIN are required for stomatal microtubule organizing centre formation. Additionally, a model where pore placement is regulated by opposing MUS and MUSL1 signaling pathways was developed. Finally, a redundant role for MUS and MUSL1 in lateral root development was confirmed.

description: Firefighters are exposed to many different contaminants during structural fires. Moreover, if their protective gear is not successfully decontaminated, firefighters are at risk of being repeatedly exposed to contaminants from previous fires. Thus, the successful removal of contaminants from firefighter turnout gear is necessary to prevent or reduce repeated exposure risks. Laundering methods can reduce the probability of re-exposure to contaminants, such as heavy metals, thus reducing repeated exposure risks. In this study, the efficiencies of heavy metal removal from the firefighter turnout gear outer textile by Decon7 cleaning solution and a standard reference detergent were compared. Nitric acid digests were used to extract metals from textile samples, which were cut from small sections of firefighter jackets, before and after their laundering with either cleaning solution. Inductively coupled plasma mass spectrometry (ICP-MS) was utilized to determine metal contents, including arsenic (As), antimony (Sb), cadmium (Cd), chromium (Cr), and lead (Pb) concentrations. Results from multiplicate samples indicated that, on average, Decon7 was significantly more efficient than a standard detergent in decreasing the concentrations of the five metals studied herein.

description: M dwarfs are the most abundant stars in the Solar Neighborhood and they are prime targets for searching for rocky planets in habitable zones. Consequently, a detailed characterization of these stars is in demand. The spectral sub-type is one of the parameters that is used for the characterization and it is traditionally derived from the observed spectra. However, obtaining the spectra of M dwarfs is expensive in terms of observation time and resources due to their intrinsic faintness. We study the performance of four machine-learning (ML) models: K-Nearest Neighbor (KNN), Random Forest (RF), Probabilistic Random Forest (PRF), and Multilayer Perceptron (MLP), in identifying the spectral sub-types of M dwarfs at a grand scale by deploying broadband photometry in the optical and near-infrared. We trained the ML models by using the spectroscopically identified M dwarfs from the Sloan Digital Sky Survey Data Release (SDSS) 7, together with their photometric colors that were derived from the SDSS, Two-Micron All-Sky Survey, and Wide-field Infrared Survey Explorer. We found that the RF, PRF, and MLP give a comparable prediction accuracy, 74%, while the KNN provides slightly lower accuracy, 71%. We also found that these models can predict the spectral sub-type of M dwarfs with ~99% accuracy within +/-1 sub-type. The five most useful features for the prediction are r-z, r-i, r-J, r-H, and g-z, and hence lacking data in all SDSS bands substantially reduces the prediction accuracy. However, we can achieve an accuracy of over 70% when the r and i magnitudes are available. Since the stars in this study are nearby (d~1300 pc for 95% of the stars), the dust extinction can reduce the prediction accuracy by only 3%. Finally, we used our optimized RF models to predict the spectral sub-types of M dwarfs from the Catalog of Cool Dwarf Targets for TESS, and we provide the optimized RF models for public use.

description: Context In the last years, cystic pancreatic lesions are often detected when clinically silent, because of the wider use of diagnostic imaging techniques. First described by Othman in 2007, “squamoid cyst of pancreatic ducts” represents a cystic dilation of ducts, lined by non-keratinized squamous epithelium. We report the first case of squamoid cyst of pancreatic ducts in Italy. Case report A 68-year-old woman presented a cystic lesion (4 cm) of the pancreatic tail as incidental finding at MRI. It had a thickened wall, no internal septa and no communication with the Wirsung duct were detected. A CT scan showed a lamellar calcification on its posterior wall. A 18F-FDG-PET was negative. Blood tests were normal, including CEA and CA 19-9. We performed a spleen-preserving distal pancreatectomy. Histology showed a unilocular cyst, with serous fluid and a fibrous wall, with multilayered epithelium without cytological atypias. Immunohistochemistry showed CK 7 positive and CK 5 negative. The patient is still alive and without disease after 42 months of follow-up. Conclusions In the English literature only seven cases resected for this cyst type have been reported. No preoperative test can achieve a definitive diagnosis, so surgical resection remains the treatment of choice in order to exclude malignancy. However, after intraoperative frozen section, a limited pancreatic resection can be performed.

description: It has been recently reported that a granular mixture in which grains differ in their restitution coefficients presents segregation: the more inelastic particles sink to the bottom. When other segregation mechanisms as buoyancy and the Brazil nut effect are present, the inelasticity induced segregation can compete with them. First, a detailed analysis, based on numerical simulations of two dimensional systems, of the competition between buoyancy and the inelasticity induced segregation is presented, finding that there is a transition line in the parameter space that determines which mechanism is dominant. In the case of neutrally buoyant particles having different sizes the inelasticity induced segregation can compete with the Brazil nut effect (BNE). Reverse Brazil nut effect (RBNE) could be obtained at large inelasticities of the intruder. At intermediate values, BNE and RBNE coexist and large inelastic particles are found both near the bottom and at the top of the system.

description: In this paper, we present sharp estimates for the covering numbers of the embedding of the reproducing kernel Hilbert space (RKHS) associated with the Weierstrass fractal kernel into the space of continuous functions. The method we apply is based on the characterization of the infinite-dimensional RKHS generated by the Weierstrass fractal kernel and it requires estimates for the norm operator of orthogonal projections on the RKHS.
Search for high-mass states with one lepton plus missing transverse momentum in proton-proton collisions at sqrt(s) = 7 TeV with the ATLAS detector

description: The ATLAS detector is used to search for high-mass states, such as heavy charged gauge bosons (W', W*) decaying to a charged lepton (electron or muon) and a neutrino. Results are presented based on the analysis of pp collisions at a center-of-mass energy of 7 TeV corresponding to an integrated luminosity of 36 pb-1. No excess beyond standard model expectations is observed. A W' with sequential standard model couplings is excluded at 95% confidence level for masses below 1.49 TeV, and a W*(charged chiral boson) for masses below 1.47 TeV.

description: Firefighters are exposed to many different contaminants during structural fires. Moreover, if their protective gear is not successfully decontaminated, firefighters are at risk of being repeatedly exposed to contaminants from previous fires. Thus, the successful removal of contaminants from firefighter turnout gear is necessary to prevent or reduce repeated exposure risks. Laundering methods can reduce the probability of re-exposure to contaminants, such as heavy metals, thus reducing repeated exposure risks. In this study, the efficiencies of heavy metal removal from the firefighter turnout gear outer textile by Decon7 cleaning solution and a standard reference detergent were compared. Nitric acid digests were used to extract metals from textile samples, which were cut from small sections of firefighter jackets, before and after their laundering with either cleaning solution. Inductively coupled plasma mass spectrometry (ICP-MS) was utilized to determine metal contents, including arsenic (As), antimony (Sb), cadmium (Cd), chromium (Cr), and lead (Pb) concentrations. Results from multiplicate samples indicated that, on average, Decon7 was significantly more efficient than a standard detergent in decreasing the concentrations of the five metals studied herein.

description: This project aims to investigate the genotoxicity of
environmentally relevant particulate nickel and cadmium
compounds in human lung cells as primary targets of
metal-induced carcinogenicity. Special focus will be given to
the question whether direct DNA damage or inhibition of DNA
repair processes causing enhancing effects with other DNA
damaging agents are predominant. In a first step, a sensitive
procedure to quantify DNA adducts of benzo[a]pyrene (B[a]P) was
established. This method is based on HPLC with fluorescence
detection and allows the specific and reproducible
quantification of 1 DNA-adduct of benzo[a]pyrene diol epoxide
(BPDE) per 108 base pairs in cultured cells. By this approach,
we demonstrated the dose-dependent generation of DNA lesions
and their repair in HeLa and A549 lung cells. The removal of DNA
adducts of BPDE was inhibited by both NiCl2 and NiO in the
non-cytotoxic concentration range. The results obtained so far
indicate that the repair inhibition by Ni(II) observed
previously also applies for lung cells and for both soluble and
insoluble nickel compounds.

Zusammenfassung

Gesamtziel des Vorhabens ist die Abklärung der Genotoxizität von
partikulären, umweltrelevanten Nickel- und Cadmiumverbindungen
in menschlichen Lungenzellen als Zielzellen der
metallinduzierten Kanzerogenese. Insbesondere soll abgeklärt
werden, ob primäre gentoxische Effekte oder
DNA-Reparaturinhibitionen im Vordergrund stehen, die in der
Folge zu Wirkungsverstärkungen in Kombination mit anderen
DNA-schädigenden Agentien führen. Hierfür wurde zunächst ein auf
HPLC mit Fluoreszenzdetektion basierendes Testsystem zum
empfindlichen Nachweis von DNA-Schäden des Benzo[a]pyrens
(B[a]P) etabliert, welches nunmehr den spezifischen und
reproduzierbaren Nachweis von 1 DNA-Addukt des Benzo[a]pyren
7,8-diol 9,10-epoxids (BPDE) pro 108 Basenpaare in Kulturzellen
ermöglicht. Mit Hilfe dieses Testsystems wurde die
dosisabhängige Induktion der DNA-Schäden und ihre Reparatur in
HeLa- und A549-Zellen gezeigt. Die Entfernung der DNA-Läsionen
wurde sowohl durch NiCl2 als auch durch NiO in
nicht-cytotoxischen Konzentrationen gehemmt. Die bislang
erhaltenen  Ergebnisse weisen darauf hin, daß die in Vorarbeiten
gezeigten Reparaturinhibitionen durch NiCl2 auch in Lungenzellen
zu beobachten sind und daß sowohl wasserlösliche als auch
weitgehend wasserunlösliche Nickelverbindungen inhibitorisch auf
die Nucleotid-Exzisionsreparatur wirken.

description: Vergleichsweise hohe Platingruppenelement-Emissionen aus
Autokatalysatoren sind in den letzten Jahren entlang von
Autobahnen und in Städten nachgewiesen worden, über deren
Toxizität bislang nur wenig bekannt ist. Ziel der
Untersuchungen im Rahmen dieses Projektes ist die Abklärung der
Bioverfügbarkeit sowie eines möglichen gentoxischen Potentials
von Platin-, Palladium- und Rhodiumverbindungen in Säugerzellen.
Im Rahmen dieser Vorstudie sollten anhand von metallischen
Platin- und Palladiumverbindungen zunächst die geplanten
Methoden auf ihre Anwendbarkeit für diese Fragestellung geprüft
und erste Abschätzungen über die Bioverfügbarkeit der PGE
getroffen werden. Dabei wurden zunächst die Größe und
physikalischen Eigenschaften der eingesetzten Partikel durch
Rasterelektronenmikroskopie und Röntgendiffraktometrie bestimmt.
Ihre Phagozytose durch A549 Lungenzellen konnte qualitativ durch
Lichtmikroskopie nachgewiesen werden. Schließlich gelang es,
eine Methode zum quantitativen Nachweis von Platin- und
Palladium-induzierten DNA-Addukten mit Hilfe der HR-ICP-MS zu
etablieren und es konnte in ersten Versuchen gezeigt werden, daß
die Exposition von A549 Lungenzellen gegenüber metallischen
Palladium- und Platinpartikeln zu einer deutlich meßbaren
DNA-Adduktbildung führt. Somit muß von einer Bioverfügbarkeit
der Partikel ausgegangen werden.

Summary

During the last years, comparatively high concentrations of
platinum group elements derived from automobile catalysts have
been detected along high-traffic streets and in cities.
Nevertheless, only little is known about their toxic
potentials. Aim of this project is to investigate the
bioavailability and potential genotoxic effects of platinum,
palladium and rhodium compounds in mammalian cells in culture.
By applying metallic platinum and palladium particles, we
examined the suitability of different methods to estimate their
bioavailabilty. The physical characteristics of the particles
were evaluated by electron microscopy and X-ray diffractometry.
Phagocytosis of the particles by A549 lung cells was
demonstrated by light microscopy. Finally, a procedure was
established to quantitate platinum- and palladium-induced DNA
adducts by HR-ICP-MS. In preliminary experiments, there was a
dose-dependent induction of DNA adducts after exposure of A549
cells towards both types of particles, indicating their
bioavailability.
