A histochemical study of the distribution and differentiation of alkaline phosphatase in the gastro-intestinal tract of steelhead trout (Salmo gairdnerii gairdnerii)
Creators: name: Prakash, Anand
Publisher: name: University of British Columbia
Year: 2012

description: The pattern of alkaline phosphatase activity in the gastro-intestinal tract of steelhead trout as revealed by Gormori-Takamatsu’s cobalt sulphide method indicates that this enzyme is intimately concerned with differentiation. During the early stages of development, the enzyme is widely distributed and localized mainly in the cytoplasm and nuclei of the gut primordium, later on, however, it tends to become electively localized in those areas where active differentiation is taking place, and disappears from other regions. Regional accumulation and loss of alkaline phosphatase throughout the period of gut differentiation points to the characteristic discontinuity in enzyme development. In the fully developed gut, phosphatase activity is localized in the gastric and intestinal regions in the lamina propria, brush border, and nuclei of the tunica mucosa. The probable role of phosphatase in these locations is discussed. Topographically variable patterns of enzyme activity obtained under different pH conditions suggest that phosphatases present in the brush border, lamina propria, and nuclei have different pH optima and are active over different pH ranges. The use of inhibitors in various concentrations in the incubating medium shows that the phosphatase present in the brush border is more resistant to high concentrations of inhibitors than that in the lamina propria. Nuclear phosphatase, on the other hand, is remarkably sensitive to lower inhibitor concentrations. Under moderate starvation, an increase in the enzyme activity is indicated in the brush border of the intestinal mucosa; acute starvation brings about structural deterioration of the mucosa and desquamation of the columnar epithelial cells, leading to diffuse phosphatase reaction. Probable factors inducing phosphatase accumulation following starvation are discussed. Differential patterns of phosphatase activity in tissue sections obtained under different substrates, pH values, inhibitor concentrations, and levels of starvation strengthen the belief of 'enzyme plurality'. The nuclear and extranuclear phosphatases behave differently and probably are not identical.

description: A new synthesized Schiff base, N-((anthracen-9-yl) methylene-2-methyl benzenamine) (AMMB), was prepared from o-toluidine and 9-anthracenecarboxaldehyde. The structure of the compound was confirmed by single crystal X-ray diffraction and characterized through various analytical tools such as high resolution mass, 1H and 13C NMR, infrared, UV-vis and elemental composition analysis. The molecular geometries of AMMB were optimized by means of DFT/B3LYP/6311-G++ (d,p) basis set. The optimized geometric parameters of the compound were concordant with the single crystal structure. The optimized structure was utilized in comparison of experimental FT-IR with calculated frequency calculation. TD-DFT analysis was performed to compute the electronic absorption of the compound. SCF-GIAO was employed to compute 1H and 13C NMR, which was consistent with the experimental results. Additionally, NLO, NBO, MEP and global reactivity parameters were also computed using the same level of theory. Hirshfield surface analysis, fingerprint plot and energy frameworks were presented to explore the intermolecular interactions within the crystal. Molecular docking study was carried out to predict the probable binding site of AMMB into lipid bilayers such as DMPC, DPPC, POPC, DLPE, DOPC and POPE. The molecular docking analysis of AMMB showed complex formation with binding affinity energy ranging from −9.3 to −3.4 kcal/mol.

description: It is shown that a small system in thermodynamic equilibrium with a finite thermostat can have a q-exponential probability distribution which closely depends on the energy nonextensivity and the particle number of the thermostat. The distribution function will reduce to the exponential one at the thermodynamic limit. However, the nonextensivity of the system should not be neglected.

description: A simple exact covariant model in which a scalar particle is modeled as a bound state of two different particles is used to elucidate relativistic aspects of electromagnetic form factors. The model form factor is computed using an exact covariant calculation of the lowest-order triangle diagram and shown to be the same as that obtained using light-front techniques. The meaning of transverse density is explained using coordinate space variables, allowing us to identify a true mean-square transverse size directly related to the form factor. We show that the rest-frame charge distribution is generally not observable because of the failure to uphold current conservation. Neutral systems of two charged constituents are shown to obey the lore that the heavier one is generally closer to the transverse origin than the lighter one. It is argued that the negative central charge density of the neutron arises, in pion-cloud models, from pions of high longitudinal momentum. The non-relativistic limit is defined precisely and the ratio of the binding energy to that of the mass of the lightest constituent is shown to govern the influence of relativistic effects. The exact relativistic formula for the form factor reduces to the familiar one of the three-dimensional Fourier transform of a square of a wave function for a very limited range of parameters. For masses that mimic the quark-di-quark model of the nucleon we find substantial relativistic corrections for any value of $Q^2$. A schematic model of the lowest s-states of nuclei is used to find that relativistic effects decrease the form factor for light nuclei but increase the form factor for heavy nuclei. Furthermore, these states are strongly influenced by relativity.

Grazie ai dati del radiotelescopio australiano Mwa, è stato possibile ottenere un miglioramento di un ordine di grandezza nella stima dell’epoca di reionizzazione. Il segnale rilevato ha più di 12 miliardi di anni, è molto debole e gli effetti sistematici rendono molto difficile estrarre le informazioni che gli astronomi stanno cercando. Ma grazie a questo lavoro è stato possibile porre dei vincoli ai modelli teorici, escludendo quelli più estremi

description: Analytical relations are derived for the amplitude of astrometric, photometric and radial velocity perturbations caused by a single rotating spot. The relative power of the star spot jitter is estimated and compared with the available data for $κ^1$ Ceti and HD 166435, as well as with numerical simulations for $κ^1$ Ceti and the Sun. A Sun-like star inclined at $i=90\degr$ at 10 pc is predicted to have a RMS jitter of 0.087 \uas in its astrometric position along the equator, and 0.38 m s$^{-1}$ in radial velocities. If the presence of spots due to stellar activity is the ultimate limiting factor for planet detection, the sensitivity of SIM Lite to Earth-like planets in habitable zones is about an order of magnitude higher that the sensitivity of prospective ultra-precise radial velocity observations of nearby stars.

description: Using the speckle camera SHARP at the 3.5m ESO NTT, Köhler and collaborators found an object ~3.5 mag fainter in K only 1.3" north-east of the T Tauri star [MR81] Ha 17 in the Corona Australis (CrA) star-forming region, which could be either a brown dwarf or a T Tauri star with an edge-on disk. We attempt to study this faint object in detail. We acquired deep VLT NACO near-infrared images at three epochs to determine, whether [MR81] Ha 17 and the nearby faint object are co-moving and to measure the infrared colors of both objects. We obtained optical and infrared spectra of both objects with the VLT using FORS and ISAAC, respectively, to determine spectral types and temperatures as well as ages and masses. The T Tauri star [MR81] Ha 17 and the faint nearby object have a projected separation of 1369.58 mas, i.e. 178 AU at 130 pc. They share the same proper motion (~5 sigma), so that they most certainly form a bound binary pair. The apparently fainter component [MR81] Ha 17 NE has a spectral type of M2e, while the apparently brighter component [MR81] Ha 17 SW, the previously known T Tauri star, has a spectral type of M4-5e. We can identify a nearly edge-on disk around [MR81] Ha 17 NE by visual inspection, which has a diameter of at least 30 to 50 AU. We are able to detect strong emission lines in [MR81] Ha 17 NE, which are almost certainly due to ongoing accretion. The NE object is detectable only by means of its scattered light. If both objects are coeval (2-3 Myr) and located at the same distance (~130 pc as CrA), then the apparently fainter [MR81] Ha 17 NE is more massive (primary) component with a nearly edge-on disk and the apparently brighter component [MR81] Ha 17 SW is less massive (com- panion). Both are low-mass T Tauri stars with masses of ~0.5 and 0.23 \pm 0.05 solar masses, respectively.

Constraining the Environment of CH+ Formation with CH3+ Observations

description: The formation of CH+ in the interstellar medium has long been an outstanding problem in chemical models. In order to probe the physical conditions of the ISM in which CH+ forms, we propose the use of CH3+ observations. The pathway to forming CH3+ begins with CH+, and a steady state analysis of CH3+ and the reaction intermediary CH2+ results in a relationship between the CH+ and CH3+ abundances. This relationship depends on the molecular hydrogen fraction, f_H2, and gas temperature, T, so observations of CH+ and CH3+ can be used to infer the properties of the gas in which both species reside. We present observations of both molecules along the diffuse cloud sight line toward Cyg OB2 No. 12. Using our computed column densities and upper limits, we put constraints on the f_H2 vs. T parameter space in which CH+ and CH3+ form. We find that average, static, diffuse molecular cloud conditions (i.e. f_H2>0.2, T~60 K) are excluded by our analysis. However, current theory suggests that non-equilibrium effects drive the reaction C+ + H_2 --> CH+ + H, endothermic by 4640 K. If we consider a higher effective temperature due to collisions between neutrals and accelerated ions, the CH3+ partition function predicts that the overall population will be spread out into several excited rotational levels. As a result, observations of more CH3+ transitions with higher signal-to-noise ratios are necessary to place any constraints on models where magnetic acceleration of ions drives the formation of CH+.

description: Antiferromagnetic heavy fermion metals close to their quantum critical points display a richness in their physical properties unanticipated by the traditional approach to quantum criticality, which describes the critical properties solely in terms of fluctuations of the order parameter. This has led to the question as to how the Kondo effect gets destroyed as the system undergoes a phase change. In one approach to the problem, Kondo lattice systems are studied through a self-consistent Bose-Fermi Kondo model within the Extended Dynamical Mean Field Theory. The quantum phase transition of the Kondo lattice is thus mapped onto that of a sub-Ohmic Bose-Fermi Kondo model. In the present article we address some aspects of the failure of the standard order-parameter functional for the the Kondo-destroying quantum critical point of the Bose-Fermi Kondo model.

description: We present a self-contained theory for the mechanical response of DNA in single molecule experiments. Our model is based on a 1D continuum description of the DNA molecule and accounts both for its elasticity and for DNA-DNA electrostatic interactions. We consider the classical loading geometry used in experiments where one end of the molecule is attached to a substrate and the other one is pulled by a tensile force and twisted by a given number of turns. We focus on configurations relevant to the limit of a large number of turns, which are made up of two phases, one with linear DNA and the other one with superhelical DNA. The model takes into account thermal fluctuations in the linear phase and electrostatic interactions in the superhelical phase. The values of the torsional stress, of the supercoiling radius and angle, and key features of the experimental extension-rotation curves, namely the slope of the linear region and thermal buckling threshold, are predicted. They are found in good agreement with experimental data.

description: We present a framework for the dynamics of causal sets and coupled matter fields, which is a simplification and generalization of an approach we recently proposed. Given a set of fields including the gravitational one, the main step in implementing our proposal consists in writing their continuum-based action using as variables for the spacetime geometry the causal order and volume element. One then discretizes the resulting expression, with a procedure designed to maintain covariance. After a discussion of the general framework, we treat in detail the case of scalar fields, Yang-Mills gauge fields and the gravitational field.

description: Epitaxial strain is a proven route to enhancing the properties of complex oxides, however, the details of how the atomic structure accommodates strain are poorly understood due to the difficulty of measuring the oxygen positions in thin films. We present a general methodology for determining the atomic structure of strained oxide films via x-ray diffraction, which we demonstrate using LaNiO3 films. The oxygen octahedral rotations and distortions have been quantified by comparing the intensities of half-order Bragg peaks, arising from the two unit cell periodicity of the octahedral rotations, with the calculated structure factor. Combining ab initio density functional calculations with these experimental results, we determine systematically how strain modifies the atomic structure of this functional oxide.

description: We report on the observation of an elementary exchange process in an optically trapped ultracold sample of atoms and Feshbach molecules. We can magnetically control the energetic nature of the process and tune it from endoergic to exoergic, enabling the observation of a pronounced threshold behavior. In contrast to relaxation to more deeply bound molecular states, the exchange process does not lead to trap loss. We find excellent agreement between our experimental observations and calculations based on the solutions of three-body Schrödinger equation in the adiabatic hyperspherical representation. The high efficiency of the exchange process is explained by the halo character of both the initial and final molecular states.

description: The interface structure of Fe/MgO(100) magnetic tunnel junctions predicted by density functional theory (DFT) depends significantly on the choice of exchange and correlation functional. Bader analysis reveals that structures obtained by relaxing the cell with the local spin-density approximation (LSDA) display a different charge transfer than those relaxed with the generalized gradient approximation (GGA). As a consequence, the electronic transport is found to be extremely sensitive to the interface structure. In particular, the conductance for the LSDA-relaxed geometry is about one order of magnitude smaller than that of the GGA-relaxed one. The high sensitivity of the electronic current to the details of the interface might explain the discrepancy between the experimental and calculated values of magnetoresistance.

description: Designing ideal human biomonitoring studies involves the selection of reliable markers of exposure in adequate biological matrix. Besides conventional matrices such as blood or urine, hair has been increasingly investigated as a promising noninvasive alternative. However, understanding the pollutant distribution between differing biological compartments is essential for reliable interpretation of data collected. Therefore, the contamination levels and the distribution of some persistent (8 perfluoroalkyl substances – PFAS – and 6 polychlorobiphenyls – PCBs) and non-persistent pollutants (2 bisphenols and 3 parabens) were investigated in paired serum and hair samples, or paired spot urine and hair samples obtained from 30 Belgian non-occupationally exposed individuals. The levels measured were close to those reported in recent larger-scale studies. PFAS, PCB and bisphenol distributions largely differed depending upon the matrix and within the same chemical family depending upon the congener. The correlation and agreement between pollutant levels in differing matrices demonstrated that the information provided is comparable only for highly chlorinated PCBs and parabens, while the classification of exposure for bisphenols was substantially different according to the matrix. The selection of the human matrix thus remains complex and might markedly bias the results obtained, especially when assessing the health risk related to chemical exposure.

description: Axions are very light, very weakly interacting particles postulated more than 30 years ago in the context of the Standard Model of particle physics. Their existence could explain the missing dark matter of the universe. However, despite intensive searches, they have yet to be detected. In this work, we show that magnetic fluctuations of topological insulators couple to the electromagnetic fields exactly like the axions, and propose several experiments to detect this dynamical axion field. In particular, we show that the axion coupling enables a nonlinear modulation of the electromagnetic field, leading to attenuated total reflection. We propose a novel optical modulators device based on this principle.

description: Examine the link between youth sports specialization and long-term lower extremity joint health after sports by comparing lower extremity function, pain, and history of sport-related injuries between young adults that were highly, moderately, and low specialized in youth sports. We used a cross-sectional design, and all data was collected using an electronic survey. Our sample included N = 356 young adults who participated in a primary sport during youth and high school sports but were no longer participating in that sport as a young adult. Participants were stratified into high (n = 111), moderate (n = 119), and low (n = 126) specialization groups using a 3-criteria sport specialization questionnaire based on youth sports participation prior to high school. We compared participants current Lower Extremity Functional Scale (LEFS) score (0–80), the proportion of participants with clinically important deficits in LEFS score (≤71/80), current lower extremity (foot/ankle, knee, hip) pain scores (0–10), and history of lower extremity (foot/ankle, knee, hip) injuries between the high, moderate, and low specialization groups. The high specialization group reported significantly lower overall LEFS scores, and a greater proportion (40%) reported clinically important deficits in LEFS scores compared to the low specialization group (20%). The high specialization group also reported greater foot/ankle and knee pain and a greater proportion of sport-related knee injuries than the low specialization group (49% vs 25%). Our findings suggest that even after discontinuing sports, young adults who were highly specialized in youth sports before high school reported clinically important deficits in lower extremity function, greater foot/ankle and knee pain, and a greater history of knee injuries than young adults who were not specialized in youth sports, suggesting a possible link between youth sports specialization and long-term lower extremity health after sports.

description: As platelet-rich plasma injection for knee osteoarthritis (OA) has increased in popularity, it has become more important to assess its effectiveness and satisfaction with its use in the context of its high cost. The purpose of this study was to determine satisfaction, commercial appeal, and effectiveness of platelet-rich plasma (PRP) for the treatment of knee OA. A retrospective review of patients who underwent PRP injection in the knee from 2016 to 2019 was performed. Various patient-reported outcomes were collected, including: satisfaction with the PRP injection (out of 100), whether the patient would want to undergo PRP injection again, whether they would recommend the injection and whether they felt that the injection was worth the cost was collected. VAS pain scores were collected and measured out of 100. Demographics and radiographical information were obtained via chart review. Statistical analyses were conducted including descriptive statistics and binary logistic and linear regressions. Overall, 114 patients were included. The mean pre-injectionpain score was 70.4, and the mean pain level decreased after injection to 36.8. Patients rated their satisfaction on average as neutral along the aforementioned continuous scale (49.2), , 50.9% stated that they would get the PRP injection again, 60.5% would recommend to a friend, and 50.9% felt the injection was worth the cost. Younger age and improved post-injection pain correlated with increasing likelihood of desiring further PRP injection. Patients on average rated satisfaction slightly below average, indicating net neutrality in terms of satisfaction with their injection. Furthermore, only half of the patients indicated that it was worth the cost and that they would receive it again. Younger age and post-injection pain relief increased desire for further injection, but pain-relief did not correlate with patients saying that the injection was worth the cost.

description: Intense laser ionization expands Einstein's photoelectric effect rules giving a wealth of phenomena widely studied over the last decades. In all cases, so far, photons were assumed to carry one unit of angular momentum. However it is now clear that photons can possess extra angular momentum, the orbital angular momentum (OAM), related to their spatial profile. We show a complete description of photoionization by OAM photons, including new selection rules involving more than one unit of angular momentum. We explore theoretically the interaction of a single electron atom located at the center of an intense ultraviolet beam bearing OAM, envisaging new scenarios for quantum optics.

description: The article continues the discussion of the media community about the confusion of two terms: âtelevision formatsâ and âtelevision genresâ. The specificity of this study is the object â sports journalism and a specialized sports TV channel in particular. It is argued that the concept of âformatâ acquires the signs of a term and requires theoretical understanding, place and role in the lexical field of sports journalism. The definition of the format of a sports television channel is formulated.

description: The form factors of the semileptonic $B_c\to S(AV)\ellν$ $(\ell=τ, μ, e)$ transitions, where S and AV denote the scalar $X_{c0}$ and axial vector $(X_{c1}, h_{c})$ mesons, are calculated within the framework of the three-point QCD sum rules. The heavy quark effective theory limit of the form factors are also obtained and compared with the values of the original transition form factors. The results of form factors are used to estimate the total decay widths and branching ratios of these transitions. A comparison of our results on branching ratios with the predictions of other approaches is also presented.

Un nuovo studio condotto dall’Università del Texas ha confermato lo scenario dell’estinzione dei dinosauri grazie all’analisi di decine di metri di roccia raccolti all’interno del cratere da impatto. Frammenti di carbone e un mix di rocce trasportate dallo tsunami, così come l’assenza di zolfo, sarebbero le prove concrete della collisione di 66 milioni di anni fa, che portò a un cambiamento climatico globale responsabile dell'estinzione di massa dei dinosauri

description: It is important to reduce the cost of correctness in programming. Dependent types and related techniques, such as type-driven programming, oﬀer ways to do so. Some parts of dependently typed programs constitute evidence of their typecorrectness and, once checked, are unnecessary for execution. These parts can easily become asymptotically larger than the remaining runtime-useful computation, which can cause linear-time algorithms run in exponential time, or worse. It would be unnacceptable, and contradict our goal of reducing the cost of correctness, to make programs run slower by only describing them more precisely. Current systems cannot erase such computation satisfactorily. By modelling erasure indirectly through type universes or irrelevance, they impose the limitations of these means to erasure. Some useless computation then cannot be erased and idiomatic programs remain asymptotically sub-optimal. This dissertation explains why we need erasure, that it is diﬀerent from other concepts like irrelevance, and proposes two ways of erasing non-computational data. One is an untyped ﬂow-based useless variable elimination, adapted for dependently typed languages, currently implemented in the Idris 1 compiler. The other is the main contribution of the dissertation: a dependently typed core calculus with erasure annotations, full dependent pattern matching, and an algorithm that infers erasure annotations from unannotated (or partially annotated) programs. I show that erasure in well-typed programs is sound in that it commutes with single-step reduction. Assuming the Church-Rosser property of reduction, I show that properties such as Subject Reduction hold, which extends the soundness result to multi-step reduction. I also show that the presented erasure inference is sound and complete with respect to the typing rules; that this approach can be extended with various forms of erasure polymorphism; that it works well with monadic I/O and foreign functions; and that it is eﬀective in that it not only removes the runtime overhead caused by dependent typing in the presented examples, but can also shorten compilation times.
