description: Προκειμένου να διατηρήσει την ομοιόσταση, ο οργανισμός έχει αναπτύξει φραγμούς. Δύο από αυτούς, ο αιματοεγκεφαλικός και ο εντερικός φραγμός μοιράζονται αρκετά κοινά χαρακτηριστικά. Το ανοσιακό σύστημα δρα ως μεσολαβητής μεταξύ των δύο φραγμών, τροποποιώντας τη λειτουργία και τη διαπερατότητα τους. Οι φραγμοί περιορίζουν την άκριτη διέλευση ανοσιακών κυττάρων υπό φυσιολογικές συνθήκες. Η υπέρμετρη ενεργοποίηση του ανοσιακού συστήματος διαταράσσει την ακεραιότητα των φραγμών και παρατηρείται σε παθολογικές καταστάσεις. Από την άλλη, το μικροβίωμα του εντέρου, ρυθμίζει λειτουργίες όπως η ωρίμανση του ανοσοποιητικού συστήματος, η αντίσταση στα παθογόνα και η διατήρηση της ακεραιότητας των φραγμών. Η επικοινωνία στον άξονα μικροβιώματος-εντέρου-εγκεφάλου είναι αμφίδρομη και πραγματοποιείται μέσω νευρικών, ενδοκρινικών και ανοσολογικών μονοπατιών σηματοδότησης. Μια διαταραγμένη μικροβιακή σύνθεση (δυσβίωση) σχετίζεται με αποσταθεροποίηση των φραγμών και τελικώς με την εκδήλωση αυτοάνοσων παθήσεων του εντέρου και του εγκεφάλου.
description: In order to create a stable environment, the human body has developed many barriers. Two of them, the blood brain barrier and the gut immune barrier share some common fundamental characteristics. The immune system dynamically impacts their function and permeability. A similarity is that under steady-state conditions both barriers limit the passage of immune cells. An uncontrollable immune reaction compromises the integrity of the barriers, a hallmark of many intestinal and neurological disorders. Gut microbiota, part of the intestinal ecosystem, is another important element regulating functions like maturation of the immune system, resistance to pathogens and maintenance of barriers. Bidirectional signaling in microbiota-gut-brain axis is regulated at neural, endocrine and immune levels. A perturbed gut microbiota composition (gut dysbiosis) can lead to dysregulation of the barriers and ultimately to the development of autoimmune disorders of the gut and the brain.

Attitudes of staff nurses toward nursing students and influencing factors
Creators: name: Tyson, Florence M.
Publisher: name: University of British Columbia
Year: 2008

description: Clinical learning experiences are an essential component of nursing education. A literature review revealed a considerable amount of anecdotal literature addressing the effect of the clinical milieu on student learning and numerous studies of nursing students' perceptions about their clinical experiences. However, there were no studies which addressed staff nurses' perceptions about working with students. Because staff nurses play a significant role in students' clinical experiences, this descriptive study was designed to assess their attitudes toward students and the factors that might influence them. A model of role adapted from Kahn et al.(1964) was used to guide the study. Sixty-four medical and/or surgical staff nurses participated in the study. A questionnaire developed by the researcher was used to collect the data. The data were analyzed quantitatively, with data from open-ended responses being subjected to content analysis to form meaning categories. The data revealed that staff nurse attitudes were positive and there were factors which contributed to their positive attitudes. For example, they enjoyed teaching students and the assistance students provided. Despite their positiveness, staff nurses expressed concerns. They had concerns about such things as the unavailability of teachers, patient safety, and disruptions in their work when students were on the units. Participants identified organizational factors, such as patient acuity and staffing, that limited the amount of time they had to spend with students. They were required to work with a variety of students from different programs and many were uncertain about their role in working with students. The study findings have implications for nursing education, service, and research related to the clinical aspect of students' education and staff nurse roles in that education.

description: In this Rapid Communication we demonstrate the applicability of an augmented Gibbs ensemble Monte Carlo approach for the phase behavior determination of model colloidal systems with short-ranged depletion attraction and long-ranged repulsion. This technique allows for a quantitative determination of the phase boundaries and ground states in such systems. We demonstrate that gelation may occur in systems of this type as the result of arrested microphase separation, even when the equilibrium state of the system is characterized by compact microphase structures.

The Exomoon Corridor for Multiple Moon Systems

Publisher: name: arXiv
Year: 2021
Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)
subject: FOS: Physical sciences

description: Recently Kipping (2021) identified the so-called "exomoon corridor", a potentially powerful new tool for identifying possible exomoon hosts, enabled by the observation that fully half of all planets hosting an exomoon will exhibit transit timing variation (TTV) periodicities of 2-4 epochs. One key outstanding problem in the search for exomoons, however, is the question of how well the methods we have developed under the single moon assumption extend to systems with multiple moons. In this work we use $N$-body simulations to examine the exomoon corridor effect in the more general case of $N \geq 1$ moons, generating realistic TTVs produced by satellite systems more akin to those seen in the outer Solar System. We find that indeed the relationship does hold for systems with up to 5 moons in both resonant and non-resonant chain configurations. Our results suggest an observational bias against finding systems with large numbers of massive moons; as the number of moons increases, total satellite mass ratios are generally required to be significantly lower in order to maintain stability, or architectures must be more finely tuned to survive. Moons produced in impact or capture scenarios may therefore dominate early detections. Finally, we examine the distribution of TTV periods measured for a large number of Kepler Objects of Interest (KOIs) and find the same characteristic exomoon corridor distribution in several cases. This could be dynamical evidence for an abundance of moons in the field, though we caution against strong inferences based on this result.

description: We present an experimental demonstration of a modified version of the entanglement-assisted "Guess my Number" protocol for the reduction of communication complexity among three separated parties. The results of experimental measurements imply that the separated parties can compute a function of distributed inputs by exchanging less classical information than by using any classical strategy. And the results also demonstrate the advantages of entanglement-enhanced communication, which is very close to quantum communication. The advantages are based on the properties of Greenberger-Horne-Zeilinger states.

description: We study electromagnetic test fields in the background of vacuum black rings using Killing vectors as vector potentials. We consider both spacetimes with a rotating S^1 and with a rotating S^2 and we demonstrate, in particular, that the gyromagnetic ratio of slightly charged black rings takes the value g=3 (this will in fact apply to a wider class of spacetimes). We also observe that a S^2-rotating black ring immersed in an external "aligned" magnetic field completely expels the magnetic flux in the extremal limit. Finally, we discuss the mutual alignment of principal null directions of the Maxwell 2-form and of the Weyl tensor, and the algebraic type of exact charged black rings. In contrast to spherical black holes, charged rings display new distinctive features and provide us with an explicit example of algebraically general (type G) spacetimes in higher dimensions. Appendix A contains some global results on black rings with a rotating 2-sphere. Appendix C shows that g=D-2 in any D>=4 dimensions for test electromagnetic fields generated by a time translation.

Local phonon mode in a fermionic bath, and its relation to Kondo effect

description: We have studied the interplay of a local phonon mode embedded in a metallic host (Holstein impurity model) using Abelian bosonization. The phonon frequency softens, which takes place in two steps: first, their frequency starts softening, and acquires finite lifetime. Then oscillations disappear from the response, and two distinct, finite dampings characterize them. Similar behaviour shows up in the spin-boson model. Due to phonons, the electrons experience an attractive, dynamic interaction. As a result, the electronic charge response enhances similarly to the spin response in the Kondo model. The local electronic density of states develops a dip around zero frequency. Thus the chance of charge-Kondo effect emerges.

description: We give an equivalent characterisation for the existence of a semi-conjugacy to an irrational rotation for conservative homeomorphisms of the two-torus. This leads to an analogue of Poincare's classification of circle homeomorphisms for conservative toral homeomorphisms with unique rotation vector and a certain bounded mean motion property. For minimal toral homeomorphisms, the result extends to arbitrary dimensions. Further, we provide a basic classification for the dynamics of non-wandering toral homeomorphisms homotopic to the identitiy.

description: A resonator with a high Q factor is generally pursued in the single-crystal diamond (SCD) microelectromechanical system (MEMS) for high-performance sensors. In this report, we investigate the oxygen etching effect of SCD on the Q factors of the SCD resonators by using the Raman spectroscopy spatial mapping. We aim to establish the etch pit effect on the Q factors of the SCD MEMS resonators. The 2D Raman imaging technique discloses the dislocations and the local stress in the SCD MEMS resonators in microscale. It is observed that the full width half maximum (FWHM) of the Raman spectra of the SCD resonators has marked relationship with the Q factors of the SCD resonators. The etch pits resulted from the dislocations have weak influence on the Q factors of the SCD resonators.

description: The successful development and optimisation of optically-driven micromachines will be greatly enhanced by the ability to computationally model the optical forces and torques applied to such devices. In principle, this can be done by calculating the light-scattering properties of such devices. However, while fast methods exist for scattering calculations for spheres and axisymmetric particles, optically-driven micromachines will almost always be more geometrically complex. Fortunately, such micromachines will typically possess a high degree of symmetry, typically discrete rotational symmetry. Many current designs for optically-driven micromachines are also mirror-symmetric about a plane. We show how such symmetries can be used to reduce the computational time required by orders of magnitude. Similar improvements are also possible for other highly-symmetric objects such as crystals. We demonstrate the efficacy of such methods by modelling the optical trapping of a cube, and show that even simple shapes can function as optically-driven micromachines.

description: Supersonic turbulence in the interstellar medium (ISM) is closely linked to the formation of stars, and hence many theories connect the stellar initial mass function (IMF) with the turbulent properties of molecular clouds. Here we test three turbulence-based IMF models (by Padoan & Nordlund 2002, Hennebelle & Chabrier 2008, and Hopkins 2012), which predict the relation between the high-mass slope ($Γ$) of the IMF, $\mathrm{d} N/\mathrm{d} \log M \propto M^Γ$ and the exponent n of the velocity power spectrum of turbulence, $E_v(k)\propto k^{-n} $, where $n\approx 2$ corresponds to typical ISM turbulence. Using hydrodynamic simulations, we drive turbulence with an unusual index of $n\approx 1$, measure $Γ$, and compare the results with $n\approx 2$. We find that reducing $n$ from 2 to 1 primarily changes the high-mass region of the IMF (beyond the median mass), where we measure high-mass slopes within the 95 per cent confidence interval of $-1.5

Cold Feedback in Cooling-Flow Galaxy Clusters

Year: 2006
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We put forward an alternative view to the Bondi-driven feedback between heating and cooling of the intra-cluster medium (ICM) in cooling flow galaxies and clusters. We adopt the popular view that the heating is due to an active galactic nucleus (AGN), i.e. a central black hole accreting mass and launching jets and/or winds. We propose that the feedback occurs with the entire cool inner region (5-30 kpc). A moderate cooling flow does exist here, and non-linear over-dense blobs of gas cool fast and are removed from the ICM before experiencing the next major AGN heating event. Some of these blobs may not accrete on the central black hole, but may form stars and cold molecular clouds. We discuss the conditions under which the dense blobs may cool to low temperatures and feed the black hole.

description: We investigated decoherence of a Josephson vortex quantum bit (qubit) in dissipative and noisy environment. As the Josephson vortex qubit (JVQ) is fabricated by using a long Josephson junction (LJJ), we use the perturbed sine-Gordon equation to describe the phase dynamics representing a two-state system and estimate the effects of quasiparticle dissipation and weakly fluctuating critical and bias currents on the relaxation time T_1 and on the dephasing time T_ϕ. We show that the critical current fluctuation does not contribute to dephasing of the qubit in the lowest order approximation. Modeling the weak current variation from magnetic field fluctuations in the LJJ by using the Gaussian colored noise with long correlation time, we show that the coherence time T_2 is limited by the low frequency current noise at very low temperatures. Also, we show that an ultra-long coherence time may be obtained from the JVQ by using experimentally accessible value of physical parameters.

description: The advancement of in-vehicle sensors provides abundant datasets to estimate parameters of car-following models that describe driver behaviors. The question of parameter identifiability of such models (i.e., whether it is possible to infer its unknown parameters from the experimental data) is a central system analysis question, and yet still remains open. This article presents both structural and practical parameter identifiability analysis on four common car-following models: (i) the constant-time headway relative-velocity (CTH-RV) model, (ii) the optimal velocity model (OV), (iii) the follow-the-leader model (FTL) and (iv) the intelligent driver model (IDM). The structural identifiability analysis is carried out using a differential geometry approach, which confirms that, in theory, all of the tested car-following systems are structurally locally identifiable, i.e., the parameters can be uniquely inferred under almost all initial condition and admissible inputs by observing the space gap alone. In a practical setting, we propose an optimization-based numerical direct test to determine parameter identifiability given a specific experimental setup (the specific initial conditions and input are known). The direct test conclusively finds distinct parameters under which the CTH-RV and FTL are not identifiable under the given initial condition and input trajectory.

description: The 90s is an exceptional period in Lithuanian history because the country declared its independence in 1990 breaking out from the 50-year lasting Soviet occupation and 14 years later entered the European Union in 2004. Like every reclaimed state Lithuania was trying to restore its political, economic, and cultural foundations facing many challenges during the 90s decade. The period of post-soviet transformation is marked by social tensions, political unrest, complicated economic situation, hyperinflation, profound corruption and criminal activity, and many other hardships. But at the same time, the country experienced rapid cultural changes and wide acceptance of Western culture and values that disrupted and transformed its national identity. This presentation explores ways how to investigate Lithuanian everyday life and culture in the 1990s by using Facebook and Instagram social network data.

Monte Carlo simulations of the "mimic system'' given by LMF theory, with short-ranged "Coulomb core" interactions in an effective single particle potential incorporating a mean-field average of the long-ranged Coulomb interactions, provide a direct test of the theory, and are in excellent agreement with more complex simulations of the full Coulomb system by Moreira and Netz [Eur. Phys. J. E 8, 33 (2002)]. A simple, generally-applicable criterion to determine the consistency parameter sigma_{min} needed for accurate use of the LMF theory is presented.

description: When galaxy formation started in the history of the Universe remains unclear. Studies of the cosmic microwave background indicate that the Universe, after initial cooling (following the Big Bang), was reheated and reionized by hot stars in newborn galaxies at a redshift in the range 6 < z < 14 (ref. 1). Though several candidate galaxies at redshift z > 7 have been identified photometrically (refs 2,3), galaxies with spectroscopically confirmed redshifts have been confined to z < 6.6 (refs. 4-8). Here we report a spectroscopic redshift of z = 6.96 (corresponding to just 750 Myr after the Big Bang) for a galaxy whose spectrum clearly shows Lyman-alpha emission at 9,682 A, indicating active star formation at a rate of about 10 M_sun/yr, where M_sun us the mass of the Sun. This demonstrates that galaxy formation was under way when the Universe was only about 6 per cent of its present age. The number density of galaxies at z = 7 seems to be only 18-36 per cent of the density at z = 6.6.

Work-family role strain among employed mothers of preschoolers: the impact of workplace support
Creators: name: Warren, Jennifer A.
Publisher: name: University of British Columbia
Year: 2008

description: This study examined the impact of work demands and workplace support on perceived work-family role strain of employed mothers with preschool age children in group daycare. Structural and psychological work demands were investigated. Components of workplace support included organizational culture, supervisor support, and family-oriented benefits offered by the workplace. The relationship between available family-oriented benefits and the use of family-oriented benefits was also assessed. In addition, moderating effects of supervisor support were investigated. The sample was recruited through licensed group daycare centers in Vancouver. Questionnaires were left at 45 daycare centers and participants were asked to return their completed questionnaires to the School of Family and Nutritional Sciences in the stamped, self addressed envelope provided. Eligible participants were mothers who were employed outside the home in position where they had an immediate supervisor, manager or boss. The respondents were 116 women who met the eligibility requirements and completed the questionnaire. The major findings of this study were that work-family role strain was associated with psychological work demands, work environment support, supervisor flexibility, and the desire to use family-oriented benefits. The results also showed that the number and percentage of family-oriented benefits used were related to the number of available family-oriented benefits. In addition, respondents were more likely to use family-oriented benefits under nonsupportive conditions. Although it was expected that supervisor support would moderate the relationship between work demands and work-family role strain, and the relationship between use of benefits and work-family role strain, the results of this study did not provide support for either prediction.

description: We present a neural-based model for relighting a half-body portrait image by simply referring to another portrait image with the desired lighting condition. Rather than following classical inverse rendering methodology that involves estimating normals, albedo and environment maps, we implicitly encode the subject and lighting in a latent space, and use these latent codes to generate relighted images by neural rendering. A key technical innovation is the use of a novel overcomplete lighting representation, which facilitates lighting interpolation in the latent space, as well as helping regularize the self-organization of the lighting latent space during training. In addition, we propose a novel multiplicative neural render that more effectively combines the subject and lighting latent codes for rendering. We also created a large-scale photorealistic rendered relighting dataset for training, which allows our model to generalize well to real images. Extensive experiments demonstrate that our system not only outperforms existing methods for referral-based portrait relighting, but also has the capability generate sequences of relighted images via lighting rotations.

description: We report the ultrafast optical pump-probe spectroscopy measurements on the recently discovered quantum critical ferromagnet CeRh$_6$Ge$_4$. Our experimental results reveal the two-stage development of the hybridization between localized $f$ moments and conduction electrons with lowering temperature, as evidenced by (1) the presence of hybridization fluctuation for temperatures from $\sim$85 K ($T^*$) to $\sim$140 K ($T^\dagger$), and (2) the emergence of collective hybridization below the coherence temperature, $T^*$, marked by the opening of an indirect gap of 2$Δ$ $\approx$12 meV. We also observe three coherent phonon modes being softened anomalously below $T^*$, reflecting directly their coupling with the emergent coherent heavy electrons. Our findings establish the universal nature of the hybridization process in different heavy fermion systems.

description: In high-energy leptonic collisions, such as at a multi-TeV muon collider, the collinear splittings of the electroweak (EW) gauge bosons and leptons are the dominant phenomena, and the scattering processes should thus be formulated in terms of the EW parton distribution functions (EW PDFs). We complete this formalism in the Standard Model to include the QCD sector and evaluate the quark and gluon PDFs inside a lepton at the double-log accuracy. The splittings of the photon and subsequently the quarks and gluons control the quark/gluon PDFs below the EW scale. The massive gauge bosons lead to substantial contributions at high scales. The jet production cross section can reach the order of a few nb (50 pb) in $e^+e^-$ ($μ^+μ^-$) collisions, at the TeV c.m. energies with a moderate acceptance cut, that governs the overall event shape up to about $p_T^j \sim 60$ GeV.

description: Στην παρούσα εργασία θα αναλυθεί η προβληματική του δικαιώματος της ζωής και ειδικότερα το ζήτημα της προστασίας του κυοφορούμενου ως ειδικής μορφής ζωής, τόσο σε αστικό, ποινικό και συνταγματικό επίπεδο στη χώρα μας, όσο και σε διεθνές επίπεδο. Η έννοια της ζωής είναι αναμφίβολη. Αμφίβολος ωστόσο καθίσταται ο ακριβής χρόνος έναρξης αυτής και για τον λόγο υπάρχει μια έντονη διαφοροποίηση των σχετικών απόψεων. Για λόγους ασφάλειας δικαίου επιβάλλεται ο σαφής καθορισμός του χρονικού σημείου έναρξης της ζωής, δεδομένου ότι ο γιατρός καλείται να αντιμετωπίσει διαφορετικές έννομες συνέπειες, ανάλογα με το αν τα αποτελέσματα του σφάλματός του εκτείνονται στο κυοφορούμενο ή στο νεογνό. Στην ελληνική νομοθεσία τίθεται το αναγκαίο νομικό πλαίσιο, ωστόσο η ραγδαία ανάπτυξη της βιοïατρικής, ιδίως στον τομέα της υποβοηθούμενης αναπαραγωγής, καθιστά πολλές φορές δυσχερή τον καθορισμό του χρονικού σημείου έναρξης της προσωπικότητας, με αποτέλεσμα να ανακύπτει η ανάγκη προσδιορισμού νέων νομικών εννοιών. Παράλληλα, με την πρόοδο της γενετικής και το δικαίωμα της τεχνητής διακοπής της κύησης, δίνεται μια νέα διάσταση στο δικαίωμα απόκτησης απογόνων, ενώ με τον τρόπο αυτό ανακύπτουν σύνθετα νομικά και κοινωνικά ζητήματα. Τα ζητήματα αυτά εγείρουν το ενδιαφέρον των θεωρητικών με την ύπαρξη έντονης διχογνωμίας στο χώρο της νομικής, της ιατρικής και της βιοηθικής, ενώ έχουν δημιουργήσει διεθνή και εγχώρια νομολογία.
description: In the present dissertation will be analyzed the issue of the right to life and in particular the issue of protection of the unborn child as a special form of life. The writer focuses on the civil, criminal, constitutional and international dimension of the subject. The meaning of life is unquestionable. However, the exact time of its start becomes doubtful, arising strong difference of opinions. For reasons of legal certainty, it is necessary to clearly define the starting point of life, as the doctor is called to face different legal consequences. The critical point is whether the consequences of his error extend to the pregnant woman or to the newborn. Greek legislation provides the necessary legal framework, however, the rapid development of biomedicine, especially in the field of assisted reproduction, often makes it difficult to determine the starting point of the personality, resulting in the need to define new legal provisions. At the same time, with the advancement of genetics and the right to abortion, a new dimension is given to the right to have descendants , while in this way complex legal and social issues arise. These issues raise the interest of theorists with the existence of intense disagreement in the field of law, medicine and bioethics, while there is significant international and domestic case law concerning this subject

description: Only a few classes of quantum algorithms are known which provide a speed-up over classical algorithms. However, these and any new quantum algorithms provide important motivation for the development of quantum computers. In this article new quantum algorithms are given which are based on quantum state tomography. These include an algorithm for the calculation of several quantum mechanical expectation values and an algorithm for the determination of polynomial factors. These quantum algorithms are important in their own right. However, it is remarkable that these quantum algorithms are immune to a large class of errors. We describe these algorithms and provide conditions for immunity.

A bandit-learning approach to multifidelity approximation

description: Multifidelity approximation is an important technique in scientific computation and simulation. In this paper, we introduce a bandit-learning approach for leveraging data of varying fidelities to achieve precise estimates of the parameters of interest. Under a linear model assumption, we formulate a multifidelity approximation as a modified stochastic bandit, and analyze the loss for a class of policies that uniformly explore each model before exploiting. Utilizing the estimated conditional mean-squared error, we propose a consistent algorithm, adaptive Explore-Then-Commit (AETC), and establish a corresponding trajectory-wise optimality result. These results are then extended to the case of vector-valued responses, where we demonstrate that the algorithm is efficient without the need to worry about estimating high-dimensional parameters. The main advantage of our approach is that we require neither hierarchical model structure nor \textit{a priori} knowledge of statistical information (e.g., correlations) about or between models. Instead, the AETC algorithm requires only knowledge of which model is a trusted high-fidelity model, along with (relative) computational cost estimates of querying each model. Numerical experiments are provided at the end to support our theoretical findings.

Studies of tumor promoters and drug-metabolic enzymes in hamster buccal pouch mucosa
Creators: name: Zhang, Dong M.
Publisher: name: University of British Columbia
Year: 2008

description: Lack of tumor promoters has been the major obstacle in the use of the hamster buccal pouch mucosa (HBPM) model. Two experiments were designed to investigate the effects of two new mouse skin tumor promoters, okadaic acid (OA) and methyl methanesulfonate (MMS), on HBPM. Short term effects of OA were studied. A single application of10 1.1.g of OA in 0.1 ml of acetone produced marked inflammation as well as an increased mitotic rate (p<0.01) as compared to that of the control. It, therefore, seems that OA possesses some essential properties of tumor promoter. Long term study is necessary to prove that it is a potent tumor promoter in HBPM. Tumor promoting effects of MMS were examined in a long term experiment. 25 hamsters were divided into 3 groups. In group I, pouches of 10 hamsters were initiated with 7,12-dimethylbenzanthracene (DMBA), then promoted with MMS for 10weeks. In group II, pouches of 10 hamsters were initiated with MMS and promoted with MMS. In group III, pouches of 5 hamsters were initiated with DMBA (right pouches) or MMS (left pouches), and promoted with acetone. The results showed that MMS had moderate tumor promoting effects but no tumor initiating effects in the model. Gamma-glutamyl transpeptidase (GGT) and placentalglutathione S-transferase (GST-P) have been found to be increased during HBPM carcinogenesis. Whether such increases are oncofetal remains to be answered. There are few studies on the normal distribution of GGT and GST-P in hamster tissues. One experiment was designed to study their tissue distributions during the development of hamster pouches and several selected organs and tissues. The results showed no GGT and GST-P activities in hamster pouches during their development. The expression of GGT and GST-P activities during HBPM carcinogenesis may represent an acquired genetic alteration instead of oncofetal reversion. GGT was found in epithelial cells, particularly those with 'brush borders', in several organs and tissues, supporting the hypothesis that GGT may participate in amino acid transportation. Rarely, GGT was also noted in mensenchymal cells. GST-P was observed in few organs and only expressed in epithelium.

description: We present infrared spectroscopy of the recurrent nova RS Ophiuchi, obtained 11.81, 20.75 and 55.71 days following its 2006 eruption. The spectra are dominated by hydrogen recombination lines, together with HeI, OI and OII lines; the electron temperature of ~10^4 K implied by the recombination spectrum suggests that we are seeing primarily the wind of the red giant, ionized by the ultraviolet flash when RS Oph erupted. However, strong coronal emission lines (i.e. emission from fine structure transitions in ions having high ionization potential) are present in the last spectrum. These imply a temperature of 930000K for the coronal gas; this is in line with x-ray observations of the 2006 eruption. The emission line widths decrease with time in a way that is consistent with the shock model for the x-ray emission.
