description: We present a detailed spectroscopic study of the hot gas toward the Galactic bulge along the 4U 1820-303 sight line by a combination analysis of emission and absorption spectra. In addition to the absorption lines of OVII Kalpha, OVII Kbeta, OVIII Kalpha and NeIX Kalpha by Chandra LTGS as shown by previous works, Suzaku detected clearly the emission lines of OVII, OVIII, NeIX and NeX from the vicinity. We used simplified plasma models with constant temperature and density. Evaluation of the background and foreground emission was performed carefully, including stellar X-ray contribution based on the recent X-ray observational results and stellar distribution simulator. If we assume that one plasma component exists in front of 4U1820-303 and the other one at the back, the obtained temperatures are T= 1.7 +/- 0.2 MK for the front-side plasma and T=3.9(+0.4-0.3) MK for the backside. This scheme is consistent with a hot and thick ISM disk as suggested by the extragalactic source observations and an X-ray bulge around the Galactic center.

description: We study the representations of large integers $n$ as sums $p_1^2 + ... + p_s^2$, where $p_1,..., p_s$ are primes with $| p_i - (n/s)^{1/2} | \le n^{θ/2}$, for some fixed $θ< 1$. When $s = 5$ we use a sieve method to show that all sufficiently large integers $n \equiv 5 \pmod {24}$ can be represented in the above form for $θ> 8/9$. This improves on earlier work by Liu, Lü and Zhan, who established a similar result for $θ> 9/10$. We also obtain estimates for the number of integers $n$ satisfying the necessary local conditions but lacking representations of the above form with $s = 3, 4$. When $s = 4$ our estimates improve and generalize recent results by Lü and Zhai, and when $s = 3$ they appear to be first of their kind.

description: Abstract 
Purpose: to compare laparoscopic two-port completely extraperitoneal (TEP) inguinal hernia repair to the traditional three-port method in order to assess the long-term results, safety, and feasibility of the procedure. Methods: A two-year prospective analysis was conducted at Theodor Bilharz Research Institute hospital between 2021 and 2023, comparing 35 patients who had two-port TEP to 35 patients who underwent traditional three-port TEP. Results: 33 patients underwent two-port TEP repairing 35 hernias, while 34 patients underwent 3 ports TEP repairing 35 hernias. 30 (85.7%) patients in group A and 32 (91.4%) in group B were male. Mean age ± SD was 42 ± 15 years in group A vs.38 ± 19 years in group B. Mean body mass index ± SD was 38.0 ± 7.7 kg/m2 in group A vs.35.0 ± 8.1 kg/m2 in group B. Indications for surgery included primary repair 33 (94.2%) in group A vs.34 (97.1%) in group B, recurrence from open repair 1 (2.9 %) in each group, and incarcerated inguinal hernia 1 (2.9 %) in group A. 33 (94.4 %) cases in group A and 34 (97.1) cases in group B were unilateral. Operative time ± SD was 48.2 ± 19.9 min in group Avs.43.7 ± 17.9 min in group B for unilateral repair and 69.4 ± 31.6 min in group A vs. 65.2 ± 29.8 min in group B for bilateral repair. Two-port TEP was successful in 33 (94.2 %). single (2.9 %) case required the addition of a third port in group A. single (2.9 %) cases were converted to TAPP repair in group A. Mean follow-up time ± SD was 9.4 ± 3.7 months. Postoperative complications included seroma 2 (5.7%) cases in group A and 1 (2.9 %) case in group B, hematoma 1 (2.9 %) in group A, chronic inguinal pain 2 (5.7%) cases in group A and 1 (2.9 %) case in group B. single (2.9 %) hernia recurred in group A. Conclusion: With applying big 3DMaxTM Mesh, two-port TEP appears to be a practical, safe, and effective procedure for laparoscopic inguinal hernia repair. It should be regarded as a viable, less invasive alternative to traditional three-port techniques.

description: This study examines behavioural and reproductive responses of bumble bees to clearcut logging, evaluating the joint influences of habitat conversion, logging amount, and floral abundance. I studied logging-induced changes in the distribution and abundance of bees across floral resources in 1.8 km2 study sites. Clearcuts were “magnet habitats” for bees, and logging amount was associated with deviations from an Ideal Free Distribution (IFD), such that undermatching consistently occurred in uncut forests, while deviations from an IFD in clearcuts depended on logging amount. Nest-searching queen bees chose artificial nest boxes as predicted by the IFD, but nest success was best explained by logging-altered resource tracking, with higher colony success in uncut forests, particularly flower-rich ones. Both studies suggest that bumble bees favour clearcuts, but not in a manner that optimizes fitness. Overall, I conclude that logging disrupts broad-scale foraging behaviour of bumble bees, potentially penalizing plants flowering in adjacent uncut forests.

Ces actions prennent différentes formes : réalisation et animation de campagnes de sensibilisation via des expositions pédagogiques et scientifiques itinérantes en France et à l’international, lobbying industriel et politique pour la mise en place de solutions durables de lutte contre la pollution plastique et, enfin, organisation d’expéditions annuelles de recherche scientifiques et participatives en Méditerranée. Ces dernières visent non seulement à cartographier la pollution plastique en Méditerranée mais également à sensibiliser et mobiliser les populations des pays riverains de la Méditerranée sur les enjeux des déchets plastiques en mer. Pour répondre à ce double objectif, un laboratoire citoyen embarqué à bord de notre navire Le Bonita a été développé, afin de permettre aux personnes volontaires provenant de la société civile d’embarquer et de participer à différents projets d’identification et de mesure de la pollution plastique. En contribuant à une meilleure connaissance de la pollution plastique en Méditerranée, ces travaux scientifiques menés sur plusieurs années visent à proposer des solutions communes et adaptées entre les pays du littoral méditerranéen, afin d ’ e n d i g u e r l e r e j e t d e p l a s t i q u e s d a n s l ' e n v i r o n n e m e n t e t d e sauvegarder cet écosystème fragile qui nous concerne tous.

description: We present nuclear spin relaxation measurements in GaAs epilayers using a new pump-probe technique in all-electrical, lateral spin-valve devices. The measured T1 times agree very well with NMR data available for T > 1 K. However, the nuclear spin relaxation rate clearly deviates from the well-established Korringa law expected in metallic samples and follows a sub-linear temperature dependence 1/T1 ~ T^0.6 for 0.1 K < T < 10 K. Further, we investigate nuclear spin inhomogeneities.

It takes into account the proton-electron interaction, external longitudinal field h, the tunneling hopping of protons, electron transfer and direct interaction between protons. The dependences of the electron concentration and mean number of protons at the site on temperature and external field are obtained. The phase transition lines from uniform phase into charge ordered phase are determined. The dependence of dynamical conductivity on temperature and field $h$ and its changes at the phase transitions are obtained.

description: Excessive joint loading has been associated with the onset and an increased rate of progression of osteoarthritis, but little is known about the effects of exercise loading on synovial fluid (SF) composition and chondrocytes viability. The purpose of this study was to load intact knee joints with two types of controlled maximal muscular contractions (low, and high intensity exercise) and identify changes in synovial fluid protein composition and chondrocyte death. We found that: 1. Chondrocytes are well protected to withstand very high loads over a short period of time, and maximal endurance loading. 2. High intensity, short duration exercise did not change total protein concentration in SF. However, it decreased the number of identifiable proteins. 3. Low intensity, long duration exercise did not change total protein concentration in the SF, but it increased the number of identifiable proteins.

Показано, что аббревиация активно вовлечена в номинацию партий, являясь неотъемлемой составляющей их номинативной практики. В анализируемом материале доминируют инициальные трехкомпонентные буквенные сокращения. Выявлено, что германская аудитория обладает высоким лингвокреативным потенциалом в осмыслении партийных наименований и их вторичных номинаций. Читатели легко создают альтернативные партийные имена и их аббревиатуры, а также владеют механизмами псевдорасшифровки сокращенных наименований. Благодаря активной медиатизации жизни партийная аббревиатура стала первостепенным вариантом наименования в политической коммуникации. Очевидно, что сегодня аббревиатурное имя политической партии является естественной частью германского языкового сознания.

description: In this paper, we investigate the Ricci dark energy model with perturbations through the joint constraints of current cosmological data sets from dynamical and geometrical perspectives. We use the full cosmic microwave background information from WMAP seven-year data, the baryon acoustic oscillations from the Sloan Digital Sky Survey and the Two Degree Galaxy Redshift Survey, and type Ia supernovae from the Union2 compilation of the Supernova Cosmology Project Collaboration. A global constraint is performed by employing the Markov chain Monte Carlo method. With the best-fitting results, we show the differences of cosmic microwave background power spectra and background evolutions for the cosmological constant model and Ricci dark energy model with perturbations.

Compensatory mechanisms in Parkinson's disease
Creators: name: Palmer, Samantha Jane
Publisher: name: University of British Columbia
Year: 2010

description: Parkinson’s disease (PD) is a common movement disorder, affecting 1% of the population over the age of 65. Pathologically, PD results from degeneration of nigral dopaminergic neurons, however symptoms do not appear until an estimated 50% of these cells are lost, suggesting compensatory mechanisms exist which mask disease onset, and may later delay progression of the disease. Compensation may take place over various spatial and temporal scales, from changes in synaptic dopamine release and synthesis that take place over a period of minutes, to recruitment of novel, widespread networks of brain regions for a specific task, which may require formation of new connections over an extended period of time. Neuroimaging techniques have recently allowed the investigation of regional and network changes in activation related to motor performance in PD, however the question of whether such changes represent a downstream effect of basal ganglia degeneration, or a compensatory change, remains difficult to determine. Here, we applied an approach from research into Alzheimer’s Disease, where abnormal activation patterns are studied in the context of tasks of increasing difficulty, such that inferences regarding their compensatory nature can be made. We show that individuals with PD are able to increase the recruitment of normal networks for a motor task (motor reserve) as a form of compensation, in addition to compensatory recruitment of novel networks to accomplish the same task as healthy controls. In particular, we observe a switch from striato-thalamo-cortical (STC) motor loops to cerebello-thalamo-cortical (CTC) loops as a compensatory strategy. This compensatory recruitment involves changes in the amplitude, spatial extent, and connectivity of regions within the CTC pathway. However, this compensation does not come without a price, since we show that compensatory CTC recruitment involving disconnection between the STC and CTC loops occurs in subjects with tremor-dominant PD, but not akinetic-rigidity-dominant PD, supporting a growing body of evidence that suggests the cerebellum plays an important role in the generation of PD tremor. Together, this body of research has implications for treatments that target the symptom of tremor in PD, as therapies which minimize tremor might also reduce beneficial aspects of compensation.

description: Giardia duodenalis, a non-invasive protozoan parasite of the upper small intestine of mammals, including humans, closely associates with intestinal epithelial cells. The pathophysiology of giardiasis includes intestinal barrier dysfunction and cytoskeletal injury; however, the mechanisms or parasitic factors involved remain unclear. The Giardia genome contains genes for cathepsin-like cysteine proteases; however, their roles are unknown. Using an in vitro model for studying host-parasite interactions, we illustrated that G. duodenalis trophozoites contain and release cathepsin B/L-like cysteine proteases. While cathepsin-like cysteine proteases are not involved in the tight junctional disruption caused by G. duodenalis, such proteases cleaved and disrupted cytoskeletal villin. This disruption of villin was sustained over time, at least in part, by host MLCK. Overall, this study establishes a reliable model for studying roles of parasitic cysteine proteases during host-parasite interactions. Further understanding of these proteases may pave the way for therapeutic development.
Bayesian optimization for monitoring the dynamic environment
Creators: name: Gao, Tianyu
Publisher: name: No Publisher Supplied
Year: 2020

description: How to sample the data in an optimization algorithm is important in an environmental monitoring problem. Ensuring the sampling method practical while obtaining useful information as much as possible to reduce time and energy cost during optimization is the key. This thesis focuses on the implementation of Bayesian Optimization (BO) to monitor a time-varying three-dimensional environment. The BO algorithm is based on the Gaussian Processes (GPs) surrogate models which are non-parametric regression methods, and uses the reward function for decision making. An uniquely designed kernal function is used in GPs to learn the underlying pattern of spatial and temporal variations. A seies of theoretical but less practical experiments are developed to prove the capability of BO, together with presenting the importance of temporal information. A continuous path planning is designed to replace the waypoint planning for a real path design in the environmetal monitoring. Furthermore, this planning is effective to balance the trade-off between the exploration and the exploitation in the optimization problem.

description: By far, in most reservoirs, even in most homogeneous ones, fluid properties are not the same all through the reservoir extent; the simplest reason is that the gravity makes a heavier fluid toward deeper zones. However, this is not always the case, because there are other reasons that may oppose this factor like a temperature gradient, capillary pressure, reservoir compartmentalization, reservoir filling, density overturn, and genesis processes. There are numerous reports of such phenomena in the literature. This variation of composition can highly affect reserve estimation, production and EOR strategies and even a completion scheme (remember how a gas-oil ratio (GOR) and miscibility can change with depth as the fluid composition changes). As a result, more and more efforts have been devoted to including these effects in reservoir simulation through the initialization of a reservoir. Furthermore, some authors have tried to utilize this phenomenon to detect reservoir compartments. In this study, we consider the effects of gravity and thermal diffusion on the change of reservoir fluid composition and predict the location of possible GOC (gas-oil contact) in a reservoir. Additionally we develop a simple model to predict the change of the plus fraction molecular weight (MW) in a nonisothermal reservoir using continuous thermodynamics and the theory of irreversible processes. In two case studies, we validate our calculation procedure for the general compositional grading, GOC detection and the plus fraction MW change in the reservoir versus the data in the literature. The computational results show that the model developed works satisfactorily. Furthermore we will run several sensitivity analyses to show what factors affect the compositional grading modeling output and when the reservoir engineer should be concerned about severe change of fluid properties caused by compositional gradient.

description: Contractile forces are essential for many developmental processes involving cell shape change and tissue deformation. Recent experiments on reconstituted actomyosin networks, the major component of the contractile machinery, have shown that active contractility occurs above a threshold motor concentration and within a window of crosslink concentration. We present a microscopic dynamic model that incorporates two essential aspects of actomyosin self-organization: the asymmetric load response of individual actin filaments and the correlated motor-driven events mimicking myosin-induced filament sliding. Using computer simulations we examine how the concentration and susceptibility of motors contribute to their collective behavior and interplay with the network connectivity to regulate macroscopic contractility. Our model is shown to capture the formation and dynamics of contractile structures and agree with the observed dependence of active contractility on microscopic parameters including the contractility onset. Cooperative action of load-resisting motors in a force-percolating structure integrates local contraction/buckling events into a global contractile state via an active coarsening process, in contrast to the flow transition driven by uncorrelated kicks of susceptible motors.

description: This thesis analyzes the first part of the work Afectos espirituales, written by the mystic and nun Francisca Josefa de Castillo (1671- 1742) in light of three stages proposed by the theorist Michel de Certeau in his book The Mystic Fable. These stages marking the path of the mystical writer are: the volo, the emptying of the “I” which takes place before the mystical experience, and the the writing process itself, in which the mystic writer proposes a metaphor that allows her soul to speak. To go further, this analysis links these phases with the theory of eroticism and the inner experience proposed by Georges Bataille. It is shown that the mystic writings of Castillo are akin to key concepts in these theories such as the quest for continuity, the emptiness of the ego in the mystical union, and the problem of language to express the ineffable.

description: Given a defaultable corporate liability in an incomplete market, we derive a new pricing model by incorporating the value of an optimal-replication portfolio and a certain reduction due to the "non-diversifiable risk". We solve the mean-variance hedging problem: finding a self-financing trading strategy that most closely approximates the payoff of the contingent claim at maturity. By applying stochastic dynamic programming to the minimization of a mean-squared error loss function under Markov-state dynamics, we derive a system of partial differential equations. In the application to evaluate a simple zero-coupon corporate bond, we solve the system of PDEs explicitly and implement the model by simulations. The results show that the yield spreads in our proposed model have comparative features with those in the Merton model. Moreover, we prove that the proposed pricing model is arbitrage-free by choosing the "non-diversifiable risk premium parameter" to be small enough.

Publisher: name: Новгородский государственный университет имени Ярослава Мудрого (НовГУ)
Year: 2020

description: The article examines the explanatory structure from the standpoint of semantic syntax, which allows, understanding the explanatory structure as a combination of modus and dictum with the participation of the technique of their combination, to expand its boundaries, on the one hand, going beyond the limits of a complex sentence and to recognize as explanatory simple and conjunctionless sentences of explanatory semantics, on the other hand, see all the explanatory constructions. The concept of its representations is proposed, which are created by changing the form of the modus predicate and its derivational capabilities, as well as the technique and form of the dictum. Such representations of an explanatory construction allow it to be included in the semantic structure of other statements in the role of a predicate, including a secondary one, an attribute, an actant. The proposed concept is illustrated by real statements of their media texts and the National Corpus of the Russian language. It is argued that it is significant for the study of the semantics of elucidation in the Russian language and semantically complex expressions.

description: The chemistry of proto-planetary disks is thought to be dominated by two major processes: photodissociation near the disk surface, and depletion on dust grains in the disk mid-plane, resulting in a layered structure with molecules located in a warm layer above the disk mid-plane. We attempt here to confront this warm molecular layer model prediction with the distribution of two key molecules for dissociation processes: CN and HCN. Using the IRAM Plateau de Bure interferometer, we obtained high spatial and spectral resolution images of the CN J=2-1 and HCN J=1-0 lines in the disks surrounding the two T-Tauri DM Tau and LkCa 15 and the Herbig Ae MWC 480. Disk properties are derived assuming power law distributions. The hyperfine structure of the observed transitions allows us to constrain the line opacities and excitation temperatures. We compare the observational results with predictions from existing chemical models, and use a simple PDR model (without freeze-out of molecules on grains and surface chemistry) to illustrate dependencies on UV field strength, grain size and gas-to-dust ratio. We also evaluate the impact of Lyman alpha radiation. The temperature ordering follows the trend found from CO lines, with DM Tau being the coldest object and MWC 480 the warmest. Although CN indicates somewhat higher excitation temperatures than HCN, the derived values in the T-Tauri disks are very low (8-10 K). They agree with results obtained from CCH, and are in contradiction with thermal and chemical model predictions. These very low temperatures, as well as geometrical constraints, suggest that substantial amounts of CN and HCN remain in the gas phase close to the disk mid-plane, and that this mid-plane is quite cold. The observed CN/HCN ratio (5-10) is in better agreement with the existence of large grains, and possibly also a substantial contribution of Lyman alpha radiation.

description: We study a bilayer consisting of an ordinary superconductor and a magnet with a spiral magnetic structure of the {\rm Ho} type. We use a self consistent solution of the Bogolioubov-de Gennes equations to evaluate the pair amplitude, the transition temperature, and the thermodynamic functions, namely, the free energy and entropy. We find that for a range of thicknesses of the magnetic layer the superconductivity is reentrant with {\it temperature} $T$: as one lowers $T$ the system turns superconducting, and when $T$ is further lowered it turns normal again. This behavior is reflected in the condensation free energy and the pair potential, which vanish both above the upper transition and below the lower one. The transition is strictly reentrant: the low and high temperature phases are the same. The entropy further reveals a range of temperatures where the superconducting state is {\it less ordered} than the normal one.

description: This thesis highlights two strategies in the management of short bowel syndrome: hormonal therapy with exogenous glucagon-like peptide-2 (GLP-2) and intraluminal nutrient infusion. Both approaches trigger an adaptive response that yields structural and functional intestinal changes to improve nutrient absorptive capacity. This study investigates (1) the effects of massive distal bowel resection, alone and in combination with exogenous GLP-2, on intestinal adaptation, with special attention to the enteric nervous system as a potential mediator; and (2) the intestinotrophic effects of dietary sucralose, medium chain triglycerides (MCT) and long chain triglycerides (LCT) after distal resection. We conclude that (1) the native adaptive response to distal resection is not recapitulated by GLP-2 therapy; (2) structural intestinotrophic effects of exogenous GLP-2 are unlikely to be mediated by neuronal nitric oxide synthase and vasoactive intestinal peptide; and (3) MCT are superior to LCT in promoting intestinal adaptation after distal resection, independent of GLP-2.

description: Introduction: With a prevalence of 5-6%, developmental coordination disorder (DCD) is one of the most common disorders of childhood. Children with DCD struggle to learn new motor skills, but the neurological mechanisms underlying the disorder are essentially unknown. Purpose: The purpose of this thesis was three-fold: (1) to present a synopsis of current literature examining the potential neural correlates of DCD; (2) to determine if patterns of brain activity differed between children with and without DCD while performing a fine-motor task; and (3) to investigate whether children with DCD are able to demonstrate improved motor learning as evidenced by increased accuracy on a fine-motor task and/or shifts in patterns of brain activation. Methods: A comprehensive literature review of possible neural correlates of DCD was conducted, which provided the background for the two studies included in this thesis. Both of these studies employed a block design and used functional magnetic resonance imaging to map patterns of brain activation associated with motor performance (Chapter 3) and motor learning (Chapter 4) of a fine-motor task. Seven children who met the diagnostic criteria for DCD (ages 8-12 years) and seven typically-developing (TD), closely age-matched children participated in the studies. Results: The literature review implicated the cerebellum as a likely source of dysfunction associated with DCD. Chapter 3 showed that, despite similar levels of behavioural motor performance, substantial differences in patterns of brain activity were noted between children with DCD and TD children. Differences in motor behaviour emerged in Chapter 4, with the DCD group showing little change in tracing accuracy compared to the improvements noted in the TD group. Neuroimaging results from Chapter 4 suggest that children with DCD may have a deficit in updating internal models of movement through under-activation of the cerebellum and/or the cerebello-thalamo-cortical pathway. Conclusion: Findings from this thesis have made several important and novel contributions to our understanding of children with DCD. This work has suggested support for several hypotheses related to the mechanisms underlying DCD and provided some of the first neuroimaging evidence to suggest possible explanations for findings of previous research in children with DCD.

description: Type 1 diabetes mellitus (DM) is associated with cognitive dysfunction, cerebral atrophy and white matter abnormalities composing diabetic leukoencephalopathy (DLE). Insulin deficiency contributes to these deficits and is amenable to replacement with intervention using intranasal insulin (I-I) delivery. An important insulin-mediated signalling pathway is propagated through phosphatidylinositol 3-kinase (PI3K) and Akt. We hypothesized that blockade of the PI3K-Akt pathway would prevent I-I’s beneficial effects in mice with DLE, and that this blockade would contribute to development of similar dysfunction in non-diabetic mice. Transgenic mice overexpressing cerebral Akt were expected to be protected from cognitive and white matter changes associated with DM. We interrogated the PI3K-Akt signalling pathway in a mouse model of Streptozotocin- induced type 1 DM over 7 months of life. Diabetic and non-diabetic mice received daily I-I (or intranasal-saline (I-S) for controls) concurrently with intranasal delivery of a PI3K inhibitor (Wortmannin) or an Akt inhibitor (API2). Mice were tested weekly for cognitive function, using a battery of behavioural tests, and endpoint magnetic resonance imaging (MRI). DM mice receiving I-I were protected from cognitive decline, while those mice receiving I-I along with either Wortmannin or API2 were subject to cognitive decline. Interestingly, non-DM mice receiving Wortmannin also developed significant cognitive dysfunction. Akt overexpressing transgenic diabetic mice were protected from cognitive decline. These results suggesting the importance of the PI3K-Akt pathway in DLE in the mouse model of DM.

description: Motivated by a mathematical model for the transport of morphogenes in biological systems, we study existence and uniqueness of entropy solutions for a mixed initial-boundary value problem associated with a nonlinear flux--limited diffusion system. From a mathematical point of view the problem behaves more as an hyperbolic system that a parabolic one.

description: Educational technology research often focuses on the development and implementation of tools for learning. The efficacy of tool development and implementation is regarded as successful if learning outcomes demonstrate an overall improvement. Studies in educational technology also examine the impact or effect of technologies on the learner. The goal of the present study was to determine if cognitive load would be manifested in a measurable physiological response. The present study examined the physiological impact of learning with static and dynamic images by measuring changes in mean cerebral blood velocity (CBV) of the right middle cerebral artery. It was determined that spatial ability has the greatest effect on changes in cerebral blood velocity and learner performance using complex images. Further, this study examined the relationship between perceived mental effort and changes in cerebral blood velocity in high and low spatial ability groups. It was determined that the while the relationships between changes in CBV and high and low spatial ability are weak, the direction of the relationships suggests a possible interaction that warrants further investigation. The findings from the present study show that spatial ability is a variable that impacts cognitive load. However, measuring specific elements of cognitive load is a challenge as they likely occur simultaneously during learning and can be difficult to isolate for investigative purposes.

description: An internal field induced resonant intensity enhancement of Raman scattering of phonon excitations in InAs nanowires is reported. The experimental observation is in good agreement with the simulated results for the scattering of light under varying incident wavelengths, originating from the enhanced internal electric field in an infinite dielectric cylinder. Our analysis demonstrates the combined effect of the first higher lying direct band gap energy (E1) and the refractive index of the InAs nanowires in the internal field induced resonant Raman scattering. Furthermore, the difference in the relative contribution of electro-optic effect and deformation potential in Raman scattering of nanowires and bulk InAs over a range of excitation energies is discussed by comparing the intensity ratio of their LO and TO phonon modes.

description: Цель исследования. Изучить и проанализировать корреляционные связи между уровнем асимметричного диметиларгинина и показателями эндотелий-зависимой вазодилатации в сравнительном аспекте у пациентов с нестабильной стенокардией и острым инфарктом миокарда. Материалы и методы. Было обследовано 104 пациента с диагнозом направления острый коронарный синдром. Из 104 пациентов у 41 была диагностирована нестабильная стенокардия и у 63 - острый инфаркт миокарда. Среди пациентов с нестабильной стенокардией было 15 пациентов с впервые возникшей стенокардией и 26 пациентов - с прогрессирующей стенокардией. В качестве группы контроля были обследованы 20 соматически здоровых лиц. Для исследования показателей эндотелий-зависимой вазодилатации был проведен ионофоретический тест с 5% ацетилхолином. Уровень асимметричного диметиларгинина определялся методом иммуноферментного анализа. Результаты. Значение показателей эндотелий-зависимой вазодилатации и уровень асимметричного диметиларгинина у всех обследуемых пациентов с острым коронарным синдромом имели статистически значимые различия с группой контроля. Значение показателя Tmax вазодилатации и уровень асимметричного диметиларгинина у обследуемых пациентов с острым коронарным синдромом было статистически значимо выше, чем в группе контроля, а значение T восстановления кровотока статистически значимо ниже, чем в группе контроля. Между значением показателей эндотелий-зависимой вазодилатации и уровнем асимметричного диметиларгинина были выявлены корреляционные взаимосвязи разной силы. Заключение. У всех обследованных пациентов с острым коронарным синдромом выявленное изменение значения показателей эндотелий-зависимой вазодилатации ассоциировано с изменением уровня асимметричного диметиларгинина. Сила выявленных взаимосвязей была больше у пациентов с острым инфарктом миокарда по сравнению с пациентами с впервые возникшей и прогрессирующей стенокардией, что может быть обусловлено влиянием резорбционно-некротического синдрома, потенциирующего усиление системного воспаления и повреждение эндотелия микрососудов.
