description: Previous studies show that prenatal shocks to embryos could have adverse impacts on health endowment at birth. Using the universe of birth data and a difference-in-difference-in-difference strategy, I find that exposure to Ramadan during prenatal development has negative birth outcomes. Exposure to a full month of fasting is associated with 96 grams lower birth-weight. These results are robust across specifications and do not appear to be driven by mothers selective fertility.

description: Cyclohexane is used as a solvent in some brands of correction fluid. Cyclohexane is sometimes used as a non-polar organic solvent, although n-hexane is more widely used for this purpose. It is frequently used as a recrystallization solvent, as many organic compounds exhibit good solubility in hot cyclohexane and poor solubility at low temperatures. Cyclohexane is also used for calibration of differential scanning calorimetry instruments. Cyclohexane vapor is used in vacuum carburizing furnaces, in heat treating equipment manufacture.

description: The formation of planets is directly linked to the evolution of the circumstellar (CS) disk from which they are born. The dissipation timescales of CS disks are, therefore, of direct astrophysical importance in evaluating the time available for planet formation. We employ Spitzer Space Telescope spectra to complete the CS disk census for the late-type members of the ~8 Myr-old eta Chamaeleontis star cluster. Of the 15 K- and M-type members, eight show excess emission. We find that the presence of a CS disk is anti-correlated with binarity, with all but one disk associated with single stars. With nine single stars in total, about 80% retain a CS disk. Of the six known or suspected close binaries the only CS disk is associated with the primary of RECX 9. No circumbinary disks have been detected. We also find that stars with disks are slow rotators with surface values of specific angular momentum j = 2-15 j_sun. All high specific angular momentum systems with j = 20-30 j_sun are confined to the primary stars of binaries. This provides novel empirical evidence for rotational disk locking and again demonstrates the much shorter disk lifetimes in close binary systems compared to single star systems. We estimate the characteristic mean disk dissipation timescale to be ~5 Myr and ~9 Myr for the binary and single star systems, respectively.

description: He proportion of elderly people in the world population is constantly increasing. With age, the risk of numerous chronic diseases and their complications also rises. Research on the subject of cellular senescence date back to the middle of the last century, and today we know that senescent cells have different morphology, metabolism, phenotypes and many other characteristics. Their main feature is the development of senescence-associated secretory phenotype (SASP), whose pro-inflammatory components affect tissues and organs, and increases the possibility of age-related diseases. The liver is the main metabolic organ of our body, and the results of previous research indicate that its regenerative capacity is greater and that it ages more slowly compared to other organs. With age, liver cells change under the influence of various stressors and the risk of developing chronic liver diseases such as non-alcoholic fatty liver disease (NAFLD), non-alcoholic steatohepatitis (NASH), alcoholic steatohepatitis (ASH) and hepatocellular carcinoma (HCC) increases. It has been proven that these diseases progress faster in the elderly population and in some cases lead to end-stage liver disease that requires transplantation. The treatment of elderly people with chronic liver diseases is a challenge and requires an individual approach as well as new research that will reveal other safe and effective therapeutic modalities.

description: Human-object interaction detection is a relatively new task in the world of computer vision and visual semantic information extraction. With the goal of machines identifying interactions that humans perform on objects, there are many real-world use cases for the research in this field. To our knowledge, this is the first general survey of the state-of-the-art and milestone works in this field. We provide a basic survey of the developments in the field of human-object interaction detection. Many works in this field use multi-stream convolutional neural network architectures, which combine features from multiple sources in the input image. Most commonly these are the humans and objects in question, as well as the spatial quality of the two. As far as we are aware, there have not been in-depth studies performed that look into the performance of each component individually. In order to provide insight to future researchers, we perform an individualized study that examines the performance of each component of a multi-stream convolutional neural network architecture for human-object interaction detection. Specifically, we examine the HORCNN architecture as it is a foundational work in the field. In addition, we provide an in-depth look at the HICO-DET dataset, a popular benchmark in the field of human-object interaction detection.

description: In this work we perform a first-principles study of the adsorption properties of an In adatom deposited on 1.75 monolayers (ML) InAs, forming a wetting layer on GaAs$(001)$ with the $α_2 (2\times4)$ or $β_2 (2\times4)$ reconstruction. The structural properties of these reconstructions have been studied: we determine the equilibrium geometry of the surfaces and their stability for various growth conditions. We have then carried out a detailed study of the potential energy surface (PES) for an In adsorbate, finding the minima and the saddle points. The main characteristics of the PES and the bonding configurations of the In adatom on the surface are analyzed by comparing with analogous studies reported in the literature, trying to extract the effects due to: (i) the compressive strain to which the InAs adlayer is subjected, (ii) the particular surface reconstruction, and (iii) the wetting layer composition. We found that, in general, stable adsorption sites are located at: (i) locations besides the As in-dimers, (ii) positions bridging two As in-dimers, (iii) between two adjacent ad-dimers (only in $β_2$), and (iv) locations bridging two As ad-dimers. We find also other shallower adsorption sites which are more reconstruction specific due to the lower symmetry of the $α_2$ reconstruction compared to the $β_2$ reconstruction.

Η καταγραφή των αποτελεσμάτων έγινε με τη χρήση ερωτηματολογίου. Η έρευνα διήρκεσε τρία χρόνια και η επεξεργασία των αποτελεσμάτων έγινε με το SPSS. Τα αποτελέσματα της στατιστικής ανάλυσης έδειξαν : Τα προγράμματα ΠΕ συμβάλλουν σημαντικά στην βελτίωση του επιπέδου γνώσεων των μαθητών. Η "δασκαλοκεντρική" μέθοδος επηρεάζει θετικότερα τη βελτίωση των γνώσεων των μαθητών συγκρινόμενη με τη "μαθητοκεντρική".

Η οικογενειακή και πολιτιστική προέλευση των μαθητών καθώς και το περιβάλλον που αναπτύσσονται (αγροτικό ή αστικό) επηρεάζουν τη μεταβολή των στάσεων των μαθητών.

description: The aim of this work is the investigation of change of knowledge, attitudes and self-declared behaviors of students G class of High School after effect of specifically drawn program of Environmetal Education (EEP) for wetlands. The recording of the results became with the use questionnaire. The research lasted three years and the treatment of results became with the SPSS. The results of statistical analysis showed : EEP contribute considerably in the improvement of level of knowledge of students. The "teacher centred" method influences more positevely the improvement of knowledge of student's comparison with "student centred". The last one encourages better the attitudes and their self-declared behaviors. The familial and cultural origin of students as well as the environment that they are developed (rural or urban) influences the change of attitudes of students. Finally it appears that speceifically drawn PPE develop positive knowledge, attitudes for the environment. However for the production of sure conclusions are required the continuation of research with similar programs in other swampy ecosystems.

description: Motivated by recent anomalies in FCNC $b\to s\ell^+\ell^-$, we study $B_1\to B_2\ell^+\ell^-(\ell=e,μ,τ)$ semi-leptonic weak decays with the SU(3) flavor symmetry, where $B_{1,2}$ are the spin-1/2 baryons of single bottomed anti-triplet $T_{b3}$, single charmed anti-triplet $T_{c3}$ or light baryon octet $T_{8}$. Using the SU(3) irreducible representation approach, we first obtain the amplitude relations among different decays, and then predict the relevant not-yet measured observables of these decays. (a) We calculate the branching ratios of the $T_{b3}\to T_8 μ^+μ^-$ and $T_{b3}\to T_8 τ^+τ^-$ in the whole $q^2$ region and in the different $q^2$ bins by the measurement of $Λ^0_b\to Λ^0 μ^+μ^-$. Many of them are obtained for the first time. In addition, the longitudinal polarization fractions and the leptonic forward-backward asymmetries of all $T_{b3}\to T_{8}\ell^+\ell^-$ decays are very similar to each other in certain $q^2$ bin due to the SU(3) flavor symmetry. (b) We analyze the upper limits of $B(T_{c3}\to T_{8}\ell^+\ell^-)$ by using the experimental upper limits of $B(Λ^+_c\to pμ^+μ^-)$ and $B(Λ^+_c\to pe^+e^-)$, and find the experimental upper limit of $B(Λ^+_c\to pμ^+μ^-)$ giving effective bounds on the relevant SU(3) flavor symmetry parameters. The predictions of $B(Ξ^0_c \to Ξ^0e^+e^-)$ and $B(Ξ^0_c \to Ξ^0μ^+μ^-)$ will be different between the single-quark transition dominant contributions and the W-exchange dominant ones. (c) As for $T_{8}\to T'_8 \ell^+\ell^-$ decays, we analyze the single-quark transition contributions and the W-exchange contributions by using two measurements of $ B(Ξ^0\to Λ^0 e^+e^-)$ and $ B(Σ^+\to pμ^+μ^-)$, and give the branching ratio predictions by assuming either single-quark transition dominant contributions or the W-exchange dominant ones.

description: Cyclodecane is a cycloalkane with ten carbon atoms. Countless organic compounds are known in which a sequence of carbon atoms, rather than being connected in a chain, closes to form a ring. Saturated hydrocarbons that contain one ring are referred to as cycloalkanes. Cycloalkanes have two fewer hydrogen atoms than an alkane with the same number of carbon atoms. Cyclopropane is the smallest cycloalkane, whereas cyclohexane is the most studied, best understood, and most important. It is customary to represent cycloalkane rings as polygons, with the understanding that each corner corresponds to a carbon atom to which is attached the requisite number of hydrogen atoms to bring its total number of bonds to four. In naming cycloalkanes, alkyl groups attached to the ring are indicated explicitly and listed in alphabetical order, and the ring is numbered so as to give the lowest locant to the first-appearing substituent. If two different directions yield equivalent locants, the direction is chosen that gives the lower number to the substituent appearing first in the name. The three carbon atoms of cyclopropane define the corners of an equilateral triangle, a geometry that requires the carbon-carbon-carbon angles to be 60°. This 60° angle is much smaller than the normal tetrahedral bond angle of 109.5° and imposes considerable strain (called angle strain) on cyclopropane. Cyclopropane is further destabilized by the torsional strain that results from having three eclipsed carbon-hydrogen bonds above the plane of the ring and three below. Cyclopropane is the only cycloalkane that is planar. Cyclobutane and higher cycloalkanes adopt nonplanar conformations in order to minimize the eclipsing of bonds on adjacent atoms. The angle strain in cyclobutane is less than in cyclopropane, whereas cyclopentane and higher cycloalkanes are virtually free of angle strain. With the exception of cyclopropane, all cycloalkanes undergo rapid internal motion involving interconversion of nonplanar puckered conformations.

How three elementary teachers integrated language and content using the knowledge framework and how their LEP students responded
Creators: name: Sampson, Brenda Louise
Publisher: name: University of British Columbia
Year: 2009

description: Researchers and teachers have been interested in how to effectively integrate language and content for the benefit of Limited English Proficient (LEP) students. One approach is the knowledge framework (Mohan, 1986) which potentially supports cooperation between teachers, helping clarify relationships between language development and content. This qualitative study describes the type of knowledge framework (KF) based language/content tasks used by both a novice KF and an experienced KF grade seven social studies teacher, and by the KF experienced LEP teacher who serviced students from both classrooms. It identifies the ways these teachers integrated language and content: by directly observing all three classrooms several hours per week for a year, by describing each teacher's classroom planning, strategies and tasks, by noting how they were the same or different for each teacher, and by noting how students responded to these strategies. Important questions were: (a) How did the two experienced KF teachers compare with the novice in their use of the framework? (b) In what ways did the experienced social studies' and LEP teachers collaborate using the KF? (c) Did the experienced KF social studies teacher use different framework based strategies than the LEP teacher? (d) How did the LEP students respond to this KF approach? Analysis suggested: (a) the novice KF teacher used parts of the framework for specific short term writing tasks; the two experienced framework teachers used it in their long term organisation across the areas of reading, writing, listening and speaking, (b) The experienced KF social studies and LEP teachers were able to collaborate by sharing similar framework based approaches and methods, (c) Similar to Mohan (1986, p.39) the experienced social studies teacher focussed on the cognitive aspects of knowledge structures in relation to the social studies curriculum; whereas the LEP teacher had a broader focus of developing LEP students' language for a variety of content area subjects, (d) The LEP students used the framework implicitly in a variety of speaking, reading and writing tasks. The two LEP students from the experienced KF classroom used the framework explicitly when writing essays, identifying knowledge structures in text, and summarizing text using student designed key visuals. Implications arise regarding the role of experience, collaboration and student development (how to assist LEP students master knowledge structure skills).

description: The SUSY CP problem is one of serious problems in construction of realistic supersymmetric standard models. We consider the problem in a framework in which adjoint chiral multiplets are introduced and gauginos have Dirac mass terms induced by a U(1) gauge interaction in the hidden sector. This is realized in hidden sector models without singlet chiral multiplets, which are favored from a recent study of the Polonyi problem. We find that the dominant contributions to electron and neutron electric dipole moments (EDMs) in the model come from phases in the supersymmetric adjoint mass terms. When the supersymmetric adjoint masses are suppressed by a factor of \sim 100 compared with the Dirac ones, the electron and neutron EDMs are suppressed below the experimental bound even if the SUSY particle masses are around 1 TeV. Thus, this model works as a framework to solve the SUSY CP problem.

Η έννοια του ποσοστού δεν μπορεί να οικοδομηθεί μέσα από μία ή μερικές δραστηριότητες αλλά μέσα από από ένα σύνολο καταστάσεων και προβλημάτων (κλασμάτων, δεκαδικών αριθμών, λόγων, αναλογιών, ισοδύναμων κλασμάτων) που επιτρέπουν στην έννοια να αναδειχτεί και να λειτουργήσει. Η προσέγγιση της έννοιας του ποσοστού γίνεται με δύο διαφορετικούς τρόπους οι οποίοι όμως έχουν πολλά κοινά χαραχτηριστικά. Η πρώτη προσέγγιση αναφέρεται στη διασύνδεση των ποσοστών με τα κλάσματα και τους δεκαδικούς.

Σύμφωνα με τη δεύτερη προσέγγιση τα ποσοστά εξετάζονται σε αντιστοιχία με τις έννοιες του λόγου και της αναλογίας.

description: The debris disc around HD 172555 was recently imaged in near-infrared polarised scattered light by the Very Large Telescope's Spectro-Polarimetric High-contrast Exoplanet REsearch instrument. Here we present optical aperture polarisation measurements of HD 172555 by the HIgh Precision Polarimetric Instrument (HIPPI), and its successor HIPPI-2 on the Anglo-Australian Telescope. We seek to refine constraints on the disc's constituent dust grains by combining our polarimetric measurements with available infrared and millimetre photometry to model the scattered light and continuum emission from the disc. We model the disc using the 3D radiative transfer code Hyperion, assuming the orientation and extent of the disc as obtained from the SPHERE observation. After correction for the interstellar medium contribution, our multi-wavelength HIPPI/-2 observations (both magnitude and orientation) are consistent with the recent SPHERE polarisation measurement with a fractional polarisation $p = 62.4 \pm 5.2$~ppm at 722.3 nm, and a position angle $θ= 67 \pm 3^{\circ}$. The multi-wavelength polarisation can be adequately replicated by compact, spherical dust grains (i.e. from Mie theory) that are around 1.2 $μ$m in size, assuming astronomical silicate composition, or 3.9 $μ$m assuming a composition derived from radiative transfer modelling of the disc. We were thus able to reproduce both the spatially resolved disc emission and polarisation with a single grain composition model and size distribution.

Simulated is the Deffuant model on a directed Barabasi-Albert network with discrete opinions and several subjects. Noticed is a focusing of the the resulting opinion distribution during the simulation towards the average value of the initial opinion distribution. A small change of the focusing is seen. A dependency of this change on the number of subjects and opinions is detected and indicates the change as a consequence of discretization the opinions. Hereby the average value of the initial opinion distribution can be identified as the guide of opinion forming.

description: The immunohistochemical detection of Neurofilament Protein (NF), Peripherin (Per), S100B protein (S100B), Neuron- Specific Enolase (NSE), Synaptophysin (Syn) and Chromogranin-A (CgA) has been implemented in this study in nerve fibres of human dental pulp, in order to identify possible differences in the expression level of these markers between normal and inflamed pulp and further, to evaluate their potential use as peripheral markers of dental innervation. Deparaffinized sections of ten normal and twenty inflamed pulp tissues were immunohistochemically stained using the PAP and streptavidin-biotin peroxidase complex, and highly purified antibodies against Neurofilament Protein, Peripherin, S100B protein, Neuron- Specific Enolase, Synaptophysin and Chromogranin-A. Positive immunostaining for Neurofilament Protein (NF), S100B protein and Neuron- Specific Enolase (NSE) was observed in both normal and inflamed dental pulp tissue, with NF and S100B showing greater labelling than NSE in normal pulp samples. An increased density of NF, S100B and NSE immunoreactive nerve bundles and fibres was observed in inflamed pulp samples compared to non-inflamed. Both normal and inflamed pulp tissue showed lack of labelling for Peripherin, Synaptophysin and Chromogranin-A. The expression of Neurofilament Protein, S100B protein and Neuron- Specific Enolase in nerve fibres of both intact and inflamed dental pulp denotes their possible application as markers of dental innervation and furthermore their potential regulatory role in particular stages of pulpal physiology. The combined negative immunostaining of both Synaptophysin and Chromogranin-A implies the presumptive absence of neuroendocrine antigens in dental pulp. Further research is required in order to clarify the expression of the Peripherin in mature dental pulp

Curriculum is ME: reflections on living and teaching dramatically

description: This thesis advances the proposition that Drama education cultivates and provides students with opportunities to analyze, reflect upon, and reconcile daily human life experiences; that Drama education opens up an effective and powerful medium for young people to create a narrative and exposition, to voice their concerns; and that Drama instruction helps students to acquire the much needed capacity to take on different roles, to explore unknown situations, to expand their intellectual capacity for creative and critical thought, insight, and empathy. I explore the role of the reflective practitioner, of teacher as researcher, and Teacher Action Research through the use of interwoven taped and transcribed personal reflections on my own Drama praxis over the course of the 1997-1998 school year; as well as opening up a diverse discourse in the field by questioning past and present assumptions about the necessity of Drama's place as an integral part of the school curriculum. I explicate the imperative for teachers to not only be sufficiently trained and well versed in Drama methodology, but to be willing participants in the cognitive apprenticeship of their students by being good teachers, pedagogues, mentors, and even role models. I advance this argument by proposing that Drama curriculum is a product of each individual teacher's abilities to credibly deliver basic elements of their own humanity to their students, and through this unique sharing, the actual language of Drama is formed.

description: We investigate temperature effects in a Fermi gas with imbalanced spin populations. From the general expression of the thermal gap equation we find, in {\it weak coupling limit}, an analytical expression for the transition temperature $T_c$ as a function of various possibilities of chemical potential and mass asymmetries between the two particle species. For a range of asymmetry between certain specific values, this equation always has two solutions for $T_c$ which has been interpreted as a reentrant phenomena or a pairing induced by temperature effect. We show that the lower $T_c$ is never related to a stable solution. The same results are obtained in {\it strong coupling limit}. The thermodynamical potential is carefully analyzed to avoid the consideration of the unstable solutions. We also obtain the tricritical points for the chemical potential and mass imbalanced cases, and beyond these points we properly minimize the thermodynamic potential to find the stable and metastable first order transition lines.

description: Cycloheptane is a cycloalkane with seven carbon atoms. Cycloheptane is used as a nonpolar solvent for the chemical industry and as an intermediate in the manufacture of chemicals. It may be derived by Clemmensen reduction from cycloheptanone. Cycloheptane is not a flat molecule, because that would give carbon-carbon-carbon bond angles much greater than the tetrahedral angle of around 109.5°. Instead, it is puckered and three-dimensional. One can ask the question of what conformations would have the same angle everywhere and all bond lengths equal. Actually, in cycloheptane the conformations will not have exactly equal bond angles and lengths everywhere, because they do not have a seven-fold rotation or improper rotation. This contrasts with the chair form of cyclohexane in which all the bond angles and lengths are equal due to symmetry.

description: Σήμερα η αισθητική παίζει καθοριστικό ρόλο στην καθημερινή οδοντιατρική πράξη, αφού διαμορφώνει τις προσδοκίες των ασθενών και επηρεάζει το επίπεδο ικανοποίησής τους από τις προσθετικές αποκαταστάσεις. Το χρώμα είναι ένας από τους σημαντικότερους παράγοντες για την αισθητική των αποκαταστάσεων και στοιχείο που συχνά προβληματίζει τον οδοντίατρο και τον ασθενή. Σκοπός της παρούσας έρευνας είναι να καταγραφούν οι τάσεις επιλογής χρώματος σε τυχαίο δείγμα οδοντιάτρων, να διερευνηθεί η τυχόν συσχέτιση των χρόνων άσκησης του επαγγέλματος με τις τάσεις επιλογής χρώματος και να διερευνηθεί η τυχόν συσχέτιση χρωματικών και αισθητικών επιλογών ανάλογα με το εάν αυτές έγιναν από γενικό οδοντίατρο, μετεκπαιδευμένο στην προσθετική οδοντίατρο ή οδοντίατρο με άλλη ειδίκευση. συλλογή των πληροφοριών έγινε μέσω δελτίων που συμπληρώθηκαν από την ερευνήτρια. Οι πληροφορίες ελήφθησαν από δύο οδοντοτεχνικά εργαστήρια της Θεσσαλονίκης. Χρησιμοποιήθηκαν τα γραπτά στοιχεία, έτσι όπως αυτά είχαν φτάσει στα εργαστήρια από 18 τυχαία επιλεγμένους οδοντιάτρους και αφορούσαν στην κατασκευή μεταλλοκεραμικών αποκαταστάσεων.
description: Today more tha ever aesthetics play a definite role in every day dental practice, because it defines the expectations of the patients and influences their satisfaction level concerning their prosthetic dental treatment. Color probably as one of the most importatn factor for the aesthetic outcome of the prosthetic rehabilitation is one of the main concerns of both the patient and the dentist. The aims of the study are to record the choices of shade in a randomly selected dentist population, to investigate if there is a correlation between the year of dental practice and shade seletion, to investigate if the shade selection varies depending on dentist's education level. All information required was collected with questionnaires completed by the investigator through 2 dental laboratories in Thessaloniki. The investigator used the written evidence, as this had reached laboratories by 18 randomly selected dentists concerning metal-ceramic restorations

description: The effect of electronic correlations on the orbital magnetization in real materials has not been explored beyond a static mean-field level. Based on the dynamical mean-field theory, the effect of electronic correlations on the orbital magnetization in layered ferromagnet VI$_3$ has been studied. A comparison drawn with the results obtained from density functional theory calculations robustly establishes the crucial role of dynamical correlations in this case. In contrast to the density functional theory that leads to negligible orbital magnetization in VI$_3$, in dynamical mean-field approach the orbital magnetization is greatly enhanced. Further analysis show that this enhancement is mainly due to the enhanced local circulations of electrons, which can be attributed to a better description of the localization behavior of correlated electrons in VI$_3$. The conclusion drawn in our study could be applicable to a wide range of layered materials in this class.

description: The universal three-body dynamics in ultra-cold binary Fermi and Fermi-Bose mixtures is studied. Two identical fermions of the mass $m$ and a particle of the mass $m_1$ with the zero-range two-body interaction in the states of the total angular momentum L=1 are considered. Using the boundary condition model for the s-wave interaction of different particles, both eigenvalue and scattering problems are treated by solving hyper-radial equations, whose terms are derived analytically. The dependencies of the three-body binding energies on the mass ratio $m/m_1$ for the positive two-body scattering length are calculated; it is shown that the ground and excited states arise at $m/m_1 \ge λ_1 \approx 8.17260$ and $m/m_1 \ge λ_2 \approx 12.91743$, respectively. For $m/m_1 \alt λ_1$ and $m/m_1 \alt λ_2$, the relevant bound states turn to narrow resonances, whose positions and widths are calculated. The 2 + 1 elastic scattering and the three-body recombination near the three-body threshold are studied and it is shown that a two-hump structure in the mass-ratio dependencies of the cross sections is connected with arising of the bound states.

description: Η ΣΝ ορίστηκε ως η παρουσία στένωσης σε βαθμό μεγαλύτερο από 70% σε μία τουλάχιστον από τις τρεις κύριες στεφανιαίες αρτηρίες. Σύμφωνα με το πόρισμα της στεφανιογραφίας 48 ασθενείς είχαν ΣΝ και 12 είχαν φυσιολογικά στεφανιαία αγγεία. Οι ασθενείς με ΣΝ χωρίστηκςν σε αυτούς με ΣΔ (14 ασθενείς) και σε αυτούς χωρίς ΣΔ (34 ασθενείς). Χρησιμοποιήθηκε έτοιμο Kit του εμπορίου και όλη η διαδικασία πραγματοποιήθηκε σύμφωνα με το πρωτόκολλο του κατασκευαστή. Στους ασθενείς με ΣΝ δεν παρατηρήθηκε στατιστικώς σημαντική διαφορά της μέσης τιμής του sRage μεταξύ διαβητικών και μη (p=0,72). Αντίθετα στους στεφανιαίους μη διαβητικούς δεν προέκυψε σημαντική συσχέτιση μεταξύ των συγκεντρώσεων του sRage και της βαρύτητας της ΣΝ (p>0,05). Οι ασθενείς με χαμηλές τιμές sRage (πρώτο και δεύτερο τεταρτημόριο) έχουν κατά 5,95 φορές μεγαλύτερο κίνδυνο να εμφανίσουν ΣΝ (p=0,04) συγκριτικά με όσους έχουν υψηλές τιμές. Επίσης οι χαμηλές τιμές του sRage προβλέπουν την νόσο ενός ή δύο αγγείων.
description: Angiography indications were either suspicion of CAD or evaluation of known CAD. Cad was defined as more than 70% luminal narrowing in at least one out of the three major coronary arteries. According to angiography results, 48 diagnosed with CAD and 12 had normal coronary vessels. The CAD cases were divided into those having DM (14 patients) and those without (34 patients). The mean value of sRAge in CAD patients revealed no significant difference between those with DM and those without DM (p=o,72). On the contrary, in nodiabetic CAD subjects there was no correlation between sRAge concentrations and the severity of CAD (p>0.05). Patients with low levels of sRage (first and second quartile) have 5.95 fold increase in CAD prevalence (p=0.04) compared to those with high sRage levels. Multiple regression logistic analysis revealed that low levels of sRage associate with single or two vessel disease

description: The paper presents an analysis of literature data on the characteristics of microbiocenoses across a wide range of infectious and somatic pathologies, as well as the results of our research on changes in the composition of the gastrointestinal tract microbiota in patients with various diseases. It is demonstrated that the microbiota responds consistently to any pathological changes occurring in the host organism, primarily manifested as a disruption in the balance between anaerobic (bifidobacteria, lactobacilli, bacteroids, clostridia, etc.) and aerobic components of the microbiocenosis. The predominance or suppression of specific types of microorganisms is primarily influenced by the composition of the individual's indigenous microbiota, rather than the specific pathology associated with dysbiosis.
Light up Dark Side of Proteins with Pure Water For NMR Visualization

description: Aggregation of specific proteins has been emerging as causes of an increasing spectrum of human diseases including all neurodegenerative diseases, while aggregation of non-specific proteins has been recently identified to be the marker of aging down to unicellular organisms. The gain of cellular toxicity is thus expected to be a common mechanism for aggregation-prone proteins to initiate diverse diseases as well as aging. However, many such proteins are “completely insoluble” and therefore could not be studied previously by high-resolution biophysical methods including NMR spectroscopy. Nevertheless, in 2005, we discovered that insoluble proteins could be in fact solubilized in unsalted water and this makes NMR as the only tool for studying atomic resolution conformations of “insoluble proteins”. Recently, we have been focused on NMR characterization of insoluble proteins/mutants causing amyotrophic lateral sclerosis (ALS) including P56S-MSP, SOD1 and TDP-43. Our results deciphered that strikingly ALS-causing mutations act to eliminate their native structures, thus rending the mutants into highly-disordered states which become extremely insoluble in vivo or in buffers. Surprisingly, the aggregation of the TDP-43 N-terminus is attributed to the coexistence of folded and unfolded states exchangeable at 14 Hz. Most unexpectedly, we decoded that these aggregation-prone proteins can transform into membrane-interacting proteins to manifest their cellular toxicity probably by: 1) disrupting membrane structures and dynamics; or/and 2) perturbing membrane-anchored signal pathways or machinery; or/and 3) interfering in the membrane remodeling. With our results added in, a general conclusion can now be reached that aggregation-prone proteins share a common potential to manifest their toxicity by attacking membranes and membrane-associated processes.
