description: ©2020. The Authors. Large-scale soil application of biochar is one of the terrestrial carbon sequestration strategies for future climate change mitigation pathways, which can also help remove and sequester pollutants from contaminated soil and water. However, black carbon emissions from biochar-amended soils can deteriorate air quality and affect human health, as the biochar particles often contain a higher amount of sorbed toxic pollutants than the soil. Yet, the extent and mechanism of inhalable particulate matter (PM10) emission from biochar-amended soils at different wind regimes have not been evaluated. Using wind tunnel experiments to simulate different wind regimes, we quantified particulate emission from sand amended with 1–4% (by weight) biochar at two size fractions: with and without <2-mm biochar. At wind speeds below the threshold speed for soil erosion, biochar application significantly increased PM10 emission by up to 400% due to the direct resuspension of inhalable biochar particles. At wind speeds above the threshold speed, emission increased by up to 300% even from biochar without inhalable fractions due to collisions of fast-moving sand particles with large biochar particles. Using a theoretical framework, we show that particulate matter emissions from biochar-amended soils could be higher than that previously expected at wind speeds below the erosion threshold wind speed for background soil. Our results indicate that current models for fugitive dust emissions may underestimate the particulate matter emission potential of biochar-amended soils and will help improve the assessment of biochar emission from amended soils.

description: © 2020 by the authors. Licensee MDPI, Basel, Switzerland. Malignant mesothelioma (MM) is a very aggressive asbestos-related cancer, for which no therapy proves to be effective. We have recently shown that the oncolytic adenovirus dl922-947 had antitumor effects in MM cell lines and murine xenografts. Previous studies demonstrated that dl922-947-induced host cell cycle checkpoint deregulation and consequent DNA lesions associated with the virus efficacy. However, the cellular DNA damage response (DDR) can counteract this virus action. Therefore, we assessed whether AZD1775, an inhibitor of the G2/M DNA damage checkpoint kinase WEE1, could enhance MM cell sensitivity to dl922-947. Through cell viability assays, we found that AZD1775 synergized with dl922-947 selectively in MM cell lines and increased dl922-947-induced cell death, which showed hallmarks of apoptosis (annexinV-positivity, caspase-dependency, BCL-XL decrease, chromatin condensation). Predictably, dl922-947 and/or AZD1775 activated the DDR, as indicated by increased levels of three main DDR players: phosphorylated histone H2AX (γ-H2AX), phospho-replication protein A (RPA)32, phospho-checkpoint kinase 1 (CHK1). Dl922-947 also increased inactive Tyr-15-phosphorylated cyclin-dependent kinase 1 (CDK1), a key WEE1 substrate, which is indicative of G2/M checkpoint activation. This increase in phospho-CDK1 was effectively suppressed by AZD1775, thus suggesting that this compound could, indeed, abrogate the dl922-947-induced DNA damage checkpoint in MM cells. Overall, our data suggest that the dl922-947-AZD1775 combination could be a feasible strategy against MM.

description: Dynamics of spectator matter break-up in non-central collisions of $^{197}$Au+ $^{197}$Au at 1000 AMeV are explored within framework of quantum molecular dynamics (QMD) model. The phase space of nucleons bound in intermediate mass fragments are studied using two clusterization subroutines. Backtracking the origin of fragments to the time of initial contact between colliding nuclei indicates that \textit{simulated annealing clusterization algorithm} (SACA) results into significant yield of projectile-like and target-like fragments. Simplest clusterization approach based on spatial correlation technique, however, predicted much lesser production probability of fragments in spectator zone.

Studying the effect of OGX-225, a novel antisense therapy, on prostate cancer cells
Creators: name: Alwaal, Amjad Hassan
Publisher: name: University of British Columbia

description: Prostate cancer (PCa) is the most common malignancy diagnosed in Canadian men. If the disease is not detected early the patients would present with metastatic disease. Metastatic PCa represents a challenge for treatment. The primary treatment at this stage is androgen ablation (castration). However, metastatic PCa invariably progress to a castration-resistant form, which does not respond to androgen ablation. This form is a lethal form of the disease, and there are several strategies that have been described to treat this form of cancer. The Insulin-like Growth Factor (IGF) system plays a pivotal role in prostate development and castration-resistant progression. It is tightly regulated by seven high affinity Insulin-like Growth Factor Binding Proteins (IGFBP 1-7). IGFBP-2 and IGFBP-5 are over-expressed in PCa and play a role in castration-resistant progression, while IGFBP-3 is downregulated and inhibits growth of PCa cells. OGX-225 is a novel second- generation antisense drug (ASO) that targets both IGFBP-2 and IGFBP-5. M. Muramaki et al, at the prostate center in Vancouver, showed in their unpublished data that it inhibits the growth PCa cells both in vitro and in vivo, and that it downregulates IGFBP-2 and IGFBP-5. In my thesis, I showed the inability to rescue PCa cells exposed to OGX-225 by adding back IGFBP-5, indicating that the action of OGX-225 is irreversible and targets several targets in addition to IGFBP-2 and IGFBP-5. I also showed the growth inhibitory effect of IGFBP-3 through a mechanism other than apoptosis, while not having an additive effect on PCa cells when combined with OGX-225. This thesis reports the multi-targeting ability of OGX-225 resulting in the inability to rescue PCa cells exposed to it, and gives some insight into the mechanism of action of IGFBP-3 and its effect when combined with OGX-225.

description: The health insurance in Bulgaria is mandatory and voluntary. The mandatory health insurance is provided by a public monopoly – the National Health Insurance Fund (NHIF) and its regional branches. The voluntary health insurance is provided by joint-stock companies licensed by the State Financial Control Commission. Private voluntary health insurance company “DZI” AD is one of the first of its kind established in Bulgaria. The goal of this study was to analyze the different types of clients of a Voluntary health insurance company in Bulgaria and calculate the economical parameters related with the use of the various insurance packages by the persons. The results showed that private voluntary health insurance company “DZI” AD has 3 groups of clients, each one with its specifics. During the years the premium income is increasing. The share premium is arising from the third group of customers- Individual customers contracts is only 3%, with the highest quota of damage in the portfolio for 2008 around 58%. Using the financial resources of the Voluntary health insurance funds, the burden on the National Healthcare Insurance fund can be decreased.

description: The 102581 flat toric elliptic fibrations over P^2 are identified among the Calabi-Yau hypersurfaces that arise from the 473800776 reflexive 4-dimensional polytopes. In order to analyze their elliptic fibration structure, we describe the precise relation between the lattice polytope and the elliptic fibration. The fiber-divisor-graph is introduced as a way to visualize the embedding of the Kodaira fibers in the ambient toric fiber. In particular in the case of non-split discriminant components, this description is far more accurate than previous studies. The discriminant locus and Kodaria fibers groups of all 102581 elliptic fibrations are computed. The maximal gauge group is SU(27), which would naively be in contradiction with 6-dimensional anomaly cancellation.

description: We present a method to systematically locate and extract capacitive and inductive losses in superconducting resonators at microwave frequencies by use of mixed-material, lumped element devices. In these devices, ultra-low loss titanium nitride was progressively replaced with aluminum in the inter-digitated capacitor and meandered inductor elements. By measuring the power dependent loss at 50 mK as the Al-TiN fraction in each element is increased, we find that at low electric field, i.e. in the single photon limit, the loss is two level system in nature and is correlated with the amount of Al capacitance rather than the Al inductance. In the high electric field limit, the remaining loss is linearly related to the product of the Al area times its inductance and is likely due to quasiparticles generated by stray radiation. At elevated temperature, additional loss is correlated with the amount of Al in the inductance, with a power independent TiN-Al interface loss term that exponentially decreases as the temperature is reduced. The TiN-Al interface loss is vanishingly small at the 50 mK base temperature.

description: Nanoflares, the basic unit of impulsive energy release may produce much of the solar background emission. Extrapolation of the energy frequency distribution of observed microflares, which follows a power law to lower energies can give an estimation of the importance of nanoflares for heating the solar corona. If the power law index is greater than 2, then the nanoflare contribution is dominant. We model time series of extreme ultraviolet emission radiance, as random flares with a power law exponent of the flare event distribution. The model is based on three key parameters, the flare rate, the flare duration and the power law exponent of the flare intensity frequency distribution. We use this model to simulate emission line radiance detected in 171 Å, observed by STEREO/EUVI and SDO/AIA. The Observed light curves are matched with simulated light curves using an Artificial Neural Network and parameter values are determined across regions of active region, quiet sun, and coronal hole. The damping rate of nanoflares is compared with radiative losses cooling time. The effect of background emission, data cadence, and network sensitivity on the key parameters of model is studied. Most of the observed light curves have a power law exponent, $α$, greater than the critical value 2. At these sites nanoflare heating could be significant.

description: Teilhabemöglichkeiten können durch mangelnde Barrierefreiheit eingeschränkt sein, dies gilt im Kontext des Sportunterrichts auch für den Lernort Sporthalle. Mit dem Hochschulseminar ‚Eine Halle für alle – den Lernort Sporthalle barrierefrei gestalten‘ wird das Ziel verfolgt, angehende Sportlehrer*innen in die Lage zu versetzen, materiell-räumliche Barrierepotenziale am Lernort Sporthalle zu identifizieren und sie im Umgang mit diesen zu stärken. Das Seminarkonzept strebt eine Theorie-Praxis-Verknüpfung an und orientiert sich hierfür an Merkmalen des situierten Lernens. Eine qualitative Interviewstudie zum Seminarkonzept dient der formativen Evaluation, setzt an der Perspektive der Studierenden an und legt den Schwerpunkt zum einen auf die Umsetzung der Merkmale des situierten Lernens und zum anderen auf den Lerngegenstand ‚Der Lernort Sporthalle unter besonderer Berücksichtigung der Barrierefreiheit‘. In diesem Beitrag werden das Seminarkonzept und die Evaluationsergebnisse dargestellt. Abstract Lack of accessibility can limit participation. In the context of physical education (PE), this also applies to the sports hall as a part of the learning environment. The higher education seminar ‚Eine Halle für alle – den Lernort Sporthalle barrierefrei gestalten‘ aims to enable pre-service PE teachers to identify potential barriers in the sports hall and to strengthen them in dealing with them. The seminar concept aims to bridge theory and practice and is based on the characteristics of situated learning. It was evaluated through a qualitative interview study. The evaluation was based on the perspective of the students and focuses on the one hand on the implementation of the characteristics of situated learning and on the other hand on the learning object 'The barrier-free sports hall'. In this article, the seminar concept and evaluation results are presented.

description: We develop a Green's function approach to quasiparticle excitations of open-shell systems within the GW approximation. It is shown that accurate calculations of the characteristic multiplet structure require a precise knowledge of the self energy and, in particular, its poles. We achieve this by constructing the self energy from appropriately chosen mean-field theories on a fine frequency grid. We apply our method to a two-site Hubbard model, several molecules and the negatively charged nitrogen-vacancy defect in diamond, and obtain good agreement with experiment and other high-level theories.

description: We investigate the interaction of magneto-acoustic waves with magnetic network elements with the aim of finding possible signatures of the magnetic shadow phenomenon in the vicinity of network elements. We carried out three-dimensional numerical simulations of magneto-acoustic wave propagation in a model solar atmosphere that is threaded by a complexly structured magnetic field, resembling that of a typical magnetic network element and of internetwork regions. High-frequency waves of 10 mHz are excited at the bottom of the simulation domain. On their way through the upper convection zone and through the photosphere and the chromosphere they become perturbed, refracted, and converted into different mode types. We applied a standard Fourier analysis to produce oscillatory power-maps of the line-of-sight velocity. In the power maps of the upper photosphere and the lower chromosphere, we clearly see the magnetic shadow: a seam of suppressed power surrounding the magnetic network elements. We demonstrate that this shadow is linked to the mode conversion process and that power maps at these height levels show the signature of three different magneto-acoustic wave modes.

description: We derive the Landau-Lifshitz-Bloch (LLB) equation for a two-component magnetic system valid up to the Curie temperature. As an example, we consider disordered GdFeCo ferrimagnet where the ultrafast optically induced magnetization switching under the action of heat alone has been recently reported. The two-component LLB equation contains the longitudinal relaxation terms responding to the exchange fields from the proper and the neighboring sublattices. We show that the sign of the longitudinal relaxation rate at high temperatures can change depending on the dynamical magnetization value and a dynamical polarisation of one material by another can occur. We discuss the differences between the LLB and the Baryakhtar equation, recently used to explain the ultrafast switching in ferrimagnets. The two-component LLB equation forms basis for the largescale micromagnetic modeling of nanostructures at high temperatures and ultrashort timescales.

description: English double-embedded clauses, from which the middle verb is omitted, are often perceived as grammatically correct and processed faster than clauses with all mandatory verbs. This phenomenon is called Grammaticality Illusion (GI). It has been hypothesised that this effect occurs as a result of a failing working memory. This is because such sentences require the reader to keep several incomplete dependencies in working memory (WM). GI has been consistently found in languages like French and English, but not in German. This led to the assumptions that if GI is caused by failing WM: German native speakers and potentially proficient speakers of German might therefore have a more robust WM. This thesis examines the role of WM in the processing of the double-embedded clauses. It also focuses on the differences in the processing of these clauses among participants in three groups: English-German bilinguals, English monolinguals and German native speakers.

The background is chosen to be anisotropic scaling solution in Einstein-Maxwell-Dilaton theory with a Liouville potential. The effects of bulk Maxwell field, an extra U(1) gauge field and probe D-branes on the DC conductivity, the DC Hall conductivity and the AC conductivity are extensively analyzed. We classify behaviors of the conductivities according to the parameter ranges in the bulk theory and characterize conditions when the holographic results can reproduce experimental data.

description: Post-transcriptional regulation of gene expression is an important cellular process that occurs in eukaryotes during development and in response to environmental cues. Subcellular mRNA localization is one type of post-transcriptional regulation that serves to control translation in a spatial and temporal manner. In higher plants, reports on subcellular mRNA localization are limited and the frequency of this mechanism in different cell types is unknown. The aim of this thesis was to optimize a fluorescence whole mount in situ hybridization approach in Arabidopsis thaliana with the goal of initiating a large scale screen for examples of subcellular mRNA localization in plants. Multiple visualization techniques were employed, including fluorescent tyramide signal amplification and single mRNA fluorescence approaches. The subcellular localization pattern of three mRNAs is reported here in seedling cotyledon and young leaf cells that were visualized using the optimized fluorescence whole mount in situ hybridization approach.

description: © 2020 by the authors. Licensee MDPI, Basel, Switzerland. Changes were evaluated over 10 years in the in vitro resistance of human periodontopathic strains of Parvimonas micra to four antibiotics. Subgingival biofilms culture positive for P. micra from 300 United States adults with severe periodontitis in 2006, and from a similar group of 300 patients in 2016, were plated onto anaerobically incubated enriched Brucella blood agar alone, or supplemented with either doxycycline (4 mg/L), clindamycin (4 mg/L), amoxicillin (8 mg/L), or metronidazole (16 mg/L). P. micra growth on antibiotic-supplemented media indicated in vitro resistance to the evaluated antibiotic concentration. P. micra resistance was significantly more frequent among patients in 2016, as compared to 2006, for doxycycline (11.3% vs. 0.3% patients; 37.7-fold increase), and clindamycin (47.3% vs. 2.0% patients; 23.7-fold increase) (both p < 0.001), whereas resistance to amoxicillin (2.3% vs. 1.0% patients) and metronidazole (0% vs. 0.3% patients) remained low and statistically unchanged between the two patient groups (p-values > 0.05). No P. micra isolates in 2006 or 2016 were jointly resistant in vitro to both amoxicillin and metronidazole. The alarming increases in subgingival P. micra resistance to doxycycline and clindamycin raise serious questions about the empiric use of these antibiotics, either locally or systemically, in the treatment of United States periodontitis patients harboring subgingival P. micra.

description: In this paper, we derive the Jarzynski equality (JE) for an isolated quantum system in three different cases: (i) the full evolution is unitary with no intermediate measurements, (ii) with intermediate measurements of arbitrary observables being performed, and (iii) with intermediate measurements whose outcomes are used to modify the external protocol (feedback). We assume that the measurements will involve errors that are purely classical in nature. Our treatment is based on path probability in state space for each realization. This is in contrast to the formal approach based on projection operator and density matrices. We find that the JE remains unaffected in the second case, but gets modified in the third case where the mutual information between the measured values with the actual eigenvalues must be incorporated into the relation.

We take into account optical losses and show that they do not degrade sensitivity significantly. We also demonstrate possible application of considered regime to Einstein Telescope.

description: We introduce the class of $n$-extremal holomorphic maps, a class that generalises both finite Blaschke products and complex geodesics, and apply the notion to the finite interpolation problem for analytic functions from the open unit disc into the symmetrised bidisc $Γ$. We show that a well-known necessary condition for the solvability of such an interpolation problem is not sufficient whenever the number of interpolation nodes is 3 or greater. We introduce a sequence $\mathcal{C}_ν, ν\geq 0,$ of necessary conditions for solvability, prove that they are of strictly increasing strength and show that $\mathcal{C}_{n-3}$ is insufficient for the solvability of an $n$-point problem for $n\geq 3$. We propose the conjecture that condition $\mathcal{C}_{n-2}$ is necessary and sufficient for the solvability of an $n$-point interpolation problem for $Γ$ and we explore the implications of this conjecture. We introduce a classification of rational $Γ$-inner functions, that is, analytic functions from the disc into $Γ$ whose radial limits at almost all points on the unit circle lie in the distinguished boundary of $Γ$. The classes are related to $n$-extremality and the conditions $\mathcal{C}_ν$; we prove numerous strict inclusions between the classes.

Material examined (N=1). 1m, 07/VIII/2005, St. 0 7 (MZUESC #707).
Distribution. Western Atlantic – Bermuda, Bahamas, Yucatan Peninsula, Guadeloupe, and Brazil (Pernambuco, Sergipe, São Paulo, and Paraná) (Christoffersen 1982; Ramos-Porto et al. 1994). Records from the eastern Pacific (Gulf of California, Ríos & Carvacho, 1982) may refer to other species (A. Anker, personal communication).
Ecological notes. Species of the S. ortmanni complex occur in various habitats, including bays and estuaries, seagrass and mud flats, tidal pools, and coral reefs. From shallow waters to 22 m (Christoffersen 1982).
Previous records in Bahia. None.
Remarks. Species complex, with at least three species in the western Atlantic and possibly two different species in the eastern Pacific (A. Anker, personal communication). Species of this complex appear to be common in the Caribbean, whereas reports from Brazil are rather rare. Christoffersen (1982) extended the southern boundary of what he believed to be S. ortmanni (actually Salmoneus n. sp. aff. ortmanni, A. Anker, personal communication) from the Caribbean to southeastern Brazil (São Paulo and Paraná). Some specimens examined by Christoffersen were collected on muddy shelf sediments. A further record, the first for northeastern Brazil, was provided by Ramos-Porto et al. (1994), who examined material from Pernambuco and Sergipe. All their specimens came from estuarine muddy bottoms and were collected during low tide. The present record reduces the gap in this species’ range between Sergipe and São Paulo.

description: In this work we perform a meta-analysis of neuroimaging data, consisting of locations of peak activations identified in 162 separate studies on emotion. Neuroimaging meta-analyses are typically performed using kernel-based methods. However, these methods require the width of the kernel to be set a priori and to be constant across the brain. To address these issues, we propose a fully Bayesian nonparametric binary regression method to perform neuroimaging meta-analyses. In our method, each location (or voxel) has a probability of being a peak activation, and the corresponding probability function is based on a spatially adaptive Gaussian Markov random field (GMRF). We also include parameters in the model to robustify the procedure against miscoding of the voxel response. Posterior inference is implemented using efficient MCMC algorithms extended from those introduced in Holmes and Held [Bayesian Anal. 1 (2006) 145--168]. Our method allows the probability function to be locally adaptive with respect to the covariates, that is, to be smooth in one region of the covariate space and wiggly or even discontinuous in another. Posterior miscoding probabilities for each of the identified voxels can also be obtained, identifying voxels that may have been falsely classified as being activated. Simulation studies and application to the emotion neuroimaging data indicate that our method is superior to standard kernel-based methods.

description: The mobility of Old Women’s phase people on the southern Alberta Plains will be explored in this research through the analysis of lithic assemblages. Due to a paucity of research concerning mobility and its influence on lithic assemblages in this region, multiple theories regarding how mobility affects the organization of technology will be explored. This strengthens any inferences regarding mobility by using multiple lines of evidence, as well as evaluates the theories efficacy in this region against each other. It was found that the use of tool form, patterns in the tools and debitage, and intersite variability provided consistent interpretations regarding the mobility of past inhabitants of the Plains. It was also found that distance-decay theory could be used to suggest a directionality of movement within a minimal seasonal round. Therefore, it is apparent that the organization of technology is a viable method for understanding mobility on the southern Alberta Plains.

description: Spherically symmetric, time-periodic oscillatons -- solutions of the Einstein-Klein-Gordon system (a massive scalar field coupled to gravity) with a spatially localized core -- are investigated by very precise numerical techniques based on spectral methods. In particular the amplitude of their standing-wave tail is determined. It is found that the amplitude of the oscillating tail is very small, but non-vanishing for the range of frequencies considered. It follows that exactly time-periodic oscillatons are not truly localized, and they can be pictured loosely as consisting of a well (exponentially) localized nonsingular core and an oscillating tail making the total mass infinite. Finite mass physical oscillatons with a well localized core -- solutions of the Cauchy-problem with suitable initial conditions -- are only approximately time-periodic. They are continuously losing their mass because the scalar field radiates to infinity. Their core and radiative tail is well approximated by that of time-periodic oscillatons. Moreover the mass loss rate of physical oscillatons is estimated from the numerical data and a semi-empirical formula is deduced. The numerical results are in agreement with those obtained analytically in the limit of small amplitude time-periodic oscillatons.

description: Transmission spectroscopy, which consists of measuring the wavelength-dependent absorption of starlight by a planet's atmosphere during a transit, is a powerful probe of atmospheric composition. However, the expected signal is typically orders of magnitude smaller than instrumental systematics, and the results are crucially dependent on the treatment of the latter. In this paper, we propose a new method to infer transit parameters in the presence of systematic noise using Gaussian processes, a technique widely used in the machine learning community for Bayesian regression and classification problems. Our method makes use of auxiliary information about the state of the instrument, but does so in a non-parametric manner, without imposing a specific dependence of the systematics on the instrumental parameters, and naturally allows for the correlated nature of the noise. We give an example application of the method to archival NICMOS transmission spectroscopy of the hot Jupiter HD 189733, which goes some way towards reconciling the controversy surrounding this dataset in the literature. Finally, we provide an appendix giving a general introduction to Gaussian processes for regression, in order to encourage their application to a wider range of problems.

description: © 2020 authors. Published by the American Physical Society. Funded by SCOAP3. We determine the nucleon axial, scalar and tensor charges within lattice quantum chromodynamics including all contributions from valence and sea quarks. We analyze three gauge ensembles simulated within the twisted mass formulation at approximately physical value of the pion mass. Two of these ensembles are simulated with two dynamical light quarks and lattice spacing a=0.094 fm and the third with a=0.08 fm includes in addition the strange and charm quarks in the sea. After comparing the results among these three ensembles, we quote as final values our most accurate analysis using the latter ensemble. For the nucleon isovector axial charge we find 1.286(23) in agreement with the experimental value. We provide the flavor decomposition of the intrinsic spin 12Δςq carried by quarks in the nucleon obtaining for the up, down, strange and charm quarks 12Δςu=0.431(8), 12Δςd=-0.212(8), 12Δςs=-0.023(4) and 12Δςc=-0.005(2), respectively. The corresponding values of the tensor and scalar charges for each quark flavor are also evaluated providing valuable input for experimental searches for beyond the standard model physics. In addition, we extract the nucleon σ-terms and find for the light quark content σπN=41.6(3.8) MeV and for the strange σs=45.6(6.2) MeV. The y-parameter that is used in phenomenological studies we find y=0.078(7).

description: New families of $E$-functions are described in the context of the compact simple Lie groups O(5) and G(2). These functions of two real variables generalize the common exponential functions and for each group, only one family is currently found in the literature. All the families are fully characterized, their most important properties are described, namely their continuous and discrete orthogonalities and decompositions of their products.

description: Real-time queue length estimation and prediction provides useful information for proactively managing transportation networks. Queue spillback from off-ramps onto main freeway lanes is a serious traffic issue that can be efficiently managed using dynamic queue information. In this thesis, a case-based reasoning algorithm combined with a Kalman filter is developed to provide real-time queue length measurements and predictions on long freeway off-ramps. Estimations are based on occupancy readings from three loop detectors installed on the ramp. The proposed method is examined using a micro-simulation model in a Quadstone Paramics package on an off-ramp‏ with a length of 650 meters. The simulation results demonstrate that the model is capable of estimating and predicting the queue length on long off-ramps in 60 second time intervals. The performance of the algorithm is examined under various demand loading scenarios, estimation time intervals and number of detectors through several experiments.

description: Background: Guidelines recommend early identification of chronic kidney disease (CKD), with targeted screening as a potential method. Methods: The See Kidney Disease (SeeKD) targeted screening program screened 5,194 participants for CKD across Canada. Participant characteristics and clinical measures, including point-of-care creatinine testing for at-risk participants to determine unrecognized CKD (estimated glomerular filtration rate < 60 mL/min/1.73m2), were obtained. Individual counselling sessions were provided to participants as a behaviour change intervention. Results: The majority of participants (88.9%) had at least one risk factor for CKD, amongst whom the prevalence of unrecognized CKD was 18.8%. The majority of respondents to the post-screening survey (89.8%) self-reported a health behaviour change 2-4 weeks after their individual counselling session. Conclusion: The SeeKD program was able to identify a high prevalence of unrecognized CKD. Individual counselling may be an important component in facilitating health behaviour change among participants at risk of CKD.

description: © 2020 by the authors. Licensee MDPI, Basel, Switzerland. Since 2016, our hospital has applied tumor testing with immunohistochemistry (IHC) in endometrial cancer in order to detect mutations of mismatch repair genes (MMR). All cases with MMR deficiency proteins expression are sent for genetic testing, except those with MLH1 protein deficiency, in which case genetic testing is performed if negative for promoter hypermethylation. The primary aim of this study was to investigate the ability of our algorithm to identify Lynch syndrome (LS). The Secondary aims were to investigate the relationship between MMR status and clinicopathological features and prognosis of primary endometrial cancer (EC). From January 2016 to December 2018, 239 patients with EC were retrospectively analyzed and subdivided according to MMR status. Patients were divided in three groups: MMR proficient, LS and Lynch-like cancer (LLC). LS was characterized by a lower age and BMI, more use of contraceptive and less use of hormonal replacement therapy, nulliparity and a trend versus a better prognosis. LLC appeared more related to MMR proficient than LS and exhibited a more aggressive behavior. Our multidisciplinary approach permitted a correct diagnosis of germline mutation in patients with newly diagnosis EC and it confirmed clinicopathologic and prognostic characteristics of LS.

description: Todos intuimos la trascendencia de todo lo que afecta a la familia para el futuro de la humanidad. También somos muy conscientes de la rapidez con que, en las últimas décadas, están cambiando nuestras sociedades y cómo la cultura es reflejo de la transformación de los modos de vida de las personas y de las familias, que hoy son muy distintas de las de hace veinte o treinta años. Estos cambios culturales no han ido, sin embargo, de la mano de un cambio en la manera de ayudar a las familias acorde con la nueva mentalidad y circunstancias. Nuestra sociedad necesita hoy una nueva mirada y un cambio cultural hacia lo familiar. Ante todo, es importante constatar que las familias ideales no existen. Y que hay que partir de la comprensión de cómo son y qué necesitan las familias reales. Después de años de trabajo, nos ha parecido un buen momento para compartir esta experiencia con quienes están en primera línea al lado de las familias. El mejor modo de iniciar y dar a conocer a un público amplio este proyecto de largo alcance, ha sido la celebración del I Workshop Internacional dedicado monográficamente al Acompañamiento Familiar.

Molecular tests support the viability of rare earth elements as proxies for fossil biomolecule preservation

description: © 2020, The Author(s). The rare earth element (REE) composition of a fossil bone reflects its chemical alteration during diagenesis. Consequently, fossils presenting low REE concentrations and/or REE profiles indicative of simple diffusion, signifying minimal alteration, have been proposed as ideal candidates for paleomolecular investigation. We directly tested this prediction by conducting multiple biomolecular assays on a well-preserved fibula of the dinosaur Edmontosaurus from the Cretaceous Hell Creek Formation previously found to exhibit low REE concentrations and steeply-declining REE profiles. Gel electrophoresis identified the presence of organic material in this specimen, and subsequent immunofluorescence and enzyme-linked immunosorbant assays identified preservation of epitopes of the structural protein collagen I. Our results thereby support the utility of REE profiles as proxies for soft tissue and biomolecular preservation in fossil bones. Based on considerations of trace element taphonomy, we also draw predictions as to the biomolecular recovery potential of additional REE profile types exhibited by fossil bones.
