Streszczenie:

PLIC-1, a newly described ubiquitin-related protein, inhibited both Jurkat migration toward SDF-1α and A431 wound healing, but the closely related PLIC-2 did not. PLIC-1 prevented the SDF-1α–induced activation of phospholipase C, decreased ligand-induced internalization of SDF-1α receptor CXCR4 and inhibited chemotaxis signaled by a transfected Gi-coupled receptor. However, PLIC-1 had no effect on Gs-mediated adenylyl cyclase activation, and inhibited only the Gβγ-dependent component of Gq-initiated increase in [Ca2+]i, which is consistent with selective inhibition of Gβγ function. PLIC-1 colocalized with G proteins in lamellae and pseudopods, and precipitated Gβγ in pull downs. Interaction with Gβγ did not require PLIC-1's ubiquitin-like or ubiquitin-associated domains, and proteasome inhibition had no effect on SDF-1α activation of phospholipase C, indicating that PLIC-1's inhibition of Gβγ did not result from effects on proteasome function. Thus, PLIC-1 inhibits Gi signaling by direct association with Gβγ; because it also interacts with CD47, a modulator of integrin function, it likely has a role integrating adhesion and signaling components of cell migration.

Streszczenie:

The activity of many signaling receptors is regulated by their endocytosis via clathrin-coated pits (CCPs). For G protein-coupled receptors (GPCRs), recruitment of the adaptor protein arrestin to activated receptors is thought to be sufficient to drive GPCR clustering in CCPs and subsequent endocytosis. We have identified an unprecedented role for the ubiquitin-like protein PLIC-2 as a negative regulator of GPCR endocytosis. Protein Linking IAP to Cytoskeleton (PLIC)-2 overexpression delayed ligand-induced endocytosis of two GPCRs: the V2 vasopressin receptor and β-2 adrenergic receptor, without affecting endocytosis of the transferrin or epidermal growth factor receptor. The closely related isoform PLIC-1 did not affect receptor endocytosis. PLIC-2 specifically inhibited GPCR concentration in CCPs, without affecting membrane recruitment of arrestin-3 to activated receptors or its cellular levels. Depletion of cellular PLIC-2 accelerated GPCR endocytosis, confirming its regulatory function at endogenous levels. The ubiquitin-like domain of PLIC-2, a ligand for ubiquitin-interacting motifs (UIMs), was required for endocytic inhibition. Interestingly, the UIM-containing endocytic adaptors epidermal growth factor receptor protein substrate 15 and Epsin exhibited preferential binding to PLIC-2 over PLIC-1. This differential interaction may underlie PLIC-2 specific effect on GPCR endocytosis. Identification of a negative regulator of GPCR clustering reveals a new function of ubiquitin-like proteins and highlights a cellular requirement for exquisite regulation of receptor dynamics.

Streszczenie:

Object The choice of surgical approach during resection of a thalamic juvenile pilocytic astrocytoma (JPA) is dictated by the location of the displaced normal thalamus and posterior limb of the internal capsule (PLIC). Diffusion tensor (DT) imaging and white matter tractography can identify the location of the PLIC in relation to the tumor and may be useful in planning the operative trajectory. Methods Diffusion tensor imaging was used to localize the PLIC on preoperative MR imaging in 6 children undergoing resection of thalamic JPAs. After review of the standard T2-weighted MR imaging sequences, the anticipated position of the PLIC was determined. This result was compared with the location of the PLIC determined by a blinded radiologist with the use of DT imaging. The utility of DT imaging in determining the surgical approach to a thalamic JPA, degree of resection, and neurological outcomes were all evaluated. Results Diffusion tensor imaging confirmed the expected location of the PLIC as approximated on conventional T2-weighted images in all 6 cases. In 1 patient in particular, unexpected medial deviation of the PLIC was identified, and this proved useful in tailoring the approach to a more lateral trajectory. Gross-total resection of all cystic and solid tumor components was confirmed on postoperative imaging in all cases. All patients experienced mild to moderate worsening of neurological status immediately following resection, but 4 of 6 patients were back to their preoperative baseline at 6-month follow-up. Conclusions Diffusion tensor imaging and white matter tractography successfully identified the white matter fibers emanating from the precentral gyrus within the PLIC in children with thalamic JPAs prior to surgery. Diffusion tensor imaging served as a valuable tool for stereotactic planning of operative approaches to thalamic JPAs. Localizing the position of the PLIC helped minimize potential neurological morbidity and facilitated gross-total resection.

Background: Periodic leg movements during sleep (PLMS) have been associated with an increased risk for cardiovascular diseases and there is a high prevalence of PLMS found in patients with obstructive sleep apnea syndrome (OSAS). We evaluated patients with transient ischemic attack (TIA) for PLMS and respiratory related leg movements (RRLM), versus a control group without TIA. Methods: Twenty-five patients with TIA and 34 patients with no vascular diagnosis were referred for polysomnography. Diagnosis of PLMS was made if the periodic leg movement index (PLMI) was ≥5 and clinical significant as PLMI ≥15. Results: There was no significant difference in PLMI ≥5 and ≥15 between patients with and without TIA. In the absence of OSAS, 2 out of 5 TIA patients (40%) had a PLMI ≥15 compared to 1 of the 19 patients without TIA (5%; p = 0.037). There was no increase in RRLMs when OSAS was present. Conclusions: TIA patients did not have higher PLMI compared to controls, and in the presence of OSAS, there was no increase in RRLMs compared to patients without TIA. In selective patients, PLMS could be associated with cardiovascular diseases, since PLMS was clinically more often found in the TIA group without OSAS.

ObjectiveWe sought to assess the prevalence, correlates, and consequences of periodic limb movements of sleep (PLMS) in persons with obstructive sleep apnea (OSA) and the effect (worsening or improvement) of continuous positive airway pressure (CPAP) therapy on PLMS in a large prospective multicenter randomized controlled trial.MethodsWe performed retrospective analyses of data from the Apnea Positive Pressure Long-term Efficacy Study, a prospective multicenter randomized controlled trial. A total of 1,105 persons with OSA enrolled in this study underwent a polysomnographic investigation at baseline, another one for CPAP titration, and another study 6 months after randomization to either active CPAP or sham CPAP.ResultsOf all participants, 19.7% had PLM index (PLMI) ≥10/hour, 14.8% had PLMI ≥15/hour, 12.1% had PLMI ≥20/hour, 9.3% had PLMI ≥25/hour, and 7.5% had PLMI ≥30/hour. The odds of having a PLMI ≥10 were higher in older participants (odds ratio [OR] 1.03, p < 0.001), men (OR 1.63. p = 0.007), those using antidepressants (OR 1.48. p = 0.048), and those with higher caffeine use (OR 1.01, p = 0.04). After controlling for OSA and depression, PLMS were associated with increased sleep latency, reduced sleep efficiency, and reduced total sleep time. No significant relationships were noted between PLMS frequency and subjective sleepiness (Epworth Sleepiness Scale score) or objective sleepiness (Maintenance of Wakefulness Test). There was no differential effect of CPAP in comparison to sham CPAP on PLMS after 6 months of therapy.ConclusionsPLMS are common in patients with OSA and are associated with a significant reduction in sleep quality over and above that conferred by OSA. Treatment with CPAP does not affect the severity of PLMS.

In this paper, we describe the synthesis of robust and non-fragile Kalman filter design for a class of uncertain linear system with polytopic uncertainties and filter gain variations. The sufficient condition of filter existence, the design method of robust non-fragile filter, and the measure of non-fragility in filter are presented via LMIs(Linear Matrix Inequality) technique. And the obtained sufficient condition can be represented as PLMIs(Parameterized Linear Matrix Inequalities) that is, coefficients of LMIs are functions of a parameter confined to a compact set. Since PLMIs generate infinite LMIs, we use relaxation technique, find a finite solution for robust non-fragile filter, and show that the resulting filter guarantees the asymptotic stability with parameter uncertainties and filter fragility. Finally, a numerical example is shown to validate the proposed design method.

Medical imaging technologies offer the benefits of faster and accurate diagnosis. When the medical imaging combined with the digitization, they offer the advantage of permanent storage and fast transmission to any geographical location. However, there is a need for efficient compression algorithms that alleviate the taxing burden of both large storage space and transmission bandwidth requirements. The Perceptually Lossless Medical Image Coder is a new image compression technique. It provides a solution to challenge of delivering clinically critical information in the shortest time possible. It embeds the visual pruning into the JPEG 2000 coding framework to achieve the optimal compression without losing the visual integrity of medical images. However, the performance of the PLMIC under certain medical image operation is still unknown. In this thesis, we investigate the performance of the PLMIC by applying linear, quadratic and cubic standard and centered B-spline interpolation filters. In order to evaluate the visual performance, a subjective assessment consisting of 30 medical images and 6 image processing experts was conducted. The perceptually lossless medical image coder was compared to the state-of-the-art JPEG-LS compliant LOCO and NLOCO image coders. The results have shown overall, there were no perceivable differences of statistical significance when the medical images were enlarged by a factor of 2. The findings of the thesis may help the researchers to further improve the coder. Additionally, it may also notify the radiologists the performance of the PLMIC coder to help them with correct diagnosis.

Aktivní mechanický plicní simulátor (iLung) nabízí možnost simulace lidského dýchání. Cílem této práce je implementovat a otestovat řídící a akviziční systém cRIO pracující v reálném čase, jako řídící jednotku simulátoru. Výsledné propojení obou zařízení je zdokumentováno ve formě tabulek a původních osazovacích výkresů, které jsou doplněny o popis funkce každého pinu. Významného zlepšení bylo dosaženo laděním motoru a modifikací proporcionálně-integračního regulátoru v řídícím programu. Tyto modifikace mají za následek významné snížení oscilací v okolí nuly. Pro zvýšení využitelnosti a přístupnosti simulátoru byl vytvořen uživatelský manuál a s ním související laboratorní cvičení. Validace funkce implementované řídící jednotky nebyla omezena pouze na jednoduché testovací rutiny, ale rozšířena na testování funkce simulátoru jako celku. Měření na simulátoru byly porovnány a diskutovány s klidovým spirometrickým vyšetřením 20ti probandů. Měření prokázala velkou míru podobnosti mezi simulovaný dýcháním iLung a klidovým lidským dýcháním.

Streszczenie:

Defects in protein folding and the proteasomal pathway have been linked with numerous neurodegenerative diseases. PLIC-1 is a Ubiquitin- like (UBL) protein that binds the ubiquitin- interacting motif (UIM) of the proteasomal subunit S5a, and has been proposed to act as a proteasomal shuttle. Here, we show the UBL of PLIC-1 also binds the UIM-containing EPS15, an endocytic protein, and they function together in the transport of aggregates to the perinuclear aggresome.
We also show PLIC-1 changes localization upon expression of an endoplasmic reticulum-associated degradation (ERAD) substrate, as well as binds an ERAD component, E4B. This indicates a role in shuttling ERAD substrates in particular to the proteasome for degradation. Taken together, this allows the proposal of a dual model for PLIC-1 function: under low aggregation, ubiquitinated proteins such as ERAD substrates are shuttled to the proteasome, but under high aggregation the proteasome is overwhelmed and PLIC-1, with EPS15, promotes aggresome formation.

Streszczenie:

The pentameric ligand gated ion channel super family plays a central role in fast synaptic communication between neurons and at the neuromuscular junction. Extensive studies on the prototypic pLGIC, the Torpedo nicotinic acetylcholine receptor (nAChR) have revealed an exquisite lipid sensitivity, with the nAChR adopting a novel uncoupled conformation in membranes lacking activating anionic and neutral lipids. The lipid-exposed transmembrane alpha-helix, M4, in each homologous subunit likely acts as a lipid sensor. One model proposes that activating lipids promote M4 “binding” to the adjacent alpha-helices, M1 and M3, to enhance interactions between the M4 C-terminus and the Cys-loop of the agonist-binding domain, with such interactions promoting coupling between the agonist site and channel gate. The first part of my thesis indirectly tests this hypothesis by exploring the effects of membrane hydrophobic thickness on nAChR function. Specifically, I tested the hypothesis that thicker membranes, which should promote alignment of M4 parallel to M1/M3 and thus helix-helix interactions, favor a coupled conformation. Although I found that the nAChR is uncoupled in all membranes tested, regardless of hydrophobic thickness, thicker membranes promote transitions from uncoupled to ultimately the desensitized state over the minutes to hours time frame. In contrast to anionic lipids, which influence function primarily via a conformational selection mechanism, membrane hydrophobic thickness influences function via a kinetic mechanism - thick membranes lower the activation energy between uncoupled and coupled conformations to promote conformational transitions. In the second part of my thesis, I used the two prokaryotic homologs, GLIC and ELIC, to explore how amino acid interactions at the interface between M4 and M1/M3 influence channel activity. Alanine scanning mutagenesis of this interface shows that disruption of almost any interaction in GLIC leads to a loss of folding and/or function, while analogous mutations in ELIC typically lead to no change or produce gains in function. Sequence comparisons with other members of the pLGIC superfamily suggest that the transmembrane domains of GLIC and ELIC represent two distinct archetypes. Each archetype may strike a different balance between the need for strong M4 binding to M1/M3 to promote folding and pentamer assembly, and the need for weaker interactions that allow for greater conformational flexibility during function.

Au niveau de la synapse, la liaison des neurotransmetteurs aux récepteurs membranaires induit l’ouverture de canaux ioniques. Le Récepteur de la Glycine (RGly) est un récepteur ionotrope impliqué dans des troubles neuronaux tels que l’addiction, la douleur chronique, ou l’hyperekplexie ; pour cette raison il est important de développer des nouveaux traitements ciblant ce récepteur. Nous avons utilisé des simulations de Dynamiques Moléculaire (DM) et d’électrophysiologie numérique afin d’évaluer la fonction des structures du RGly disponibles et montré qu’aucune d’entre elles ne satisfait les propriétés fonctionnelles de l’état ouvert. Grâce aux simulations de DM, nous avons caractérisé une nouvelle conformation du RGly, qui est compatible avec cet état. Nous avons souligné le rôle majeur des portails latéraux pour la perméation des ions. Nous avons proposé un protocole, nommé pharmacologie dépendante de l’état, pour identifier des molécules modulatrices de protéines allostériques
Signals within neurons are mostly transmitted through chemical synapses. Signal transduction arises from the binding of neurotransmitters to membrane receptors in order to open ion channels. The Glycine Receptor (GlyR) is an ionotropic receptor which is involved in several neurological disorders such as addiction, chronic pain, or hyperekplexia. Because of its implication in human diseases, it is interesting to design novel drugs targeting this receptor. We used Molecular Dynamics (MD) simulations and computational electrophysiology to probe the function of available GlyR structures. We showed that none of the experimental structures display the physiological behavior of the conductive state. Using MD simulations, we captured a novel conformation of the GlyR compatible with a conductive state and demonstrated the importance of lateral portals for ionic permeation. Lastly, we proposed an original protocol, named state-based pharmacology, to discover modulators of allosteric proteins

The aim of the thesis is to valuate economic effectivity of radon mitigation countermeasures co-financed by the state applied in family houses which display high radon level. Feasibility of the mitigation is analysed without concering financing source. Furthermore, the project is valuated from the point of view of the house owner and from the state's point of view. Presence of residental radon is increasing lung cancer probability, radon has notable healt effects. Costs and benefit of the hypothetic project are vauated in CBA analysis. The author finds the project unfeasible. CBA is discussed as a suitable economic tool for fiding alternative technological method aiming to social effectivity. Providing feasible change of remediation parametres caused positive social value of the project, socioeconomic flow in the state point of view would remain negative. Therefore, state participation on the radon mitigation countermeasures of private family houses is not reccomended.

Websites of ALA, CILIP, and ALIA were also consulted to get the idea of the working of professional bodies in the field of LIS. The proposed PLIC will be a statutory professional body set up under an Act of parliament. It will register the professionals and will establish code of conduct for their members. The council will be responsible for accreditation of professional training institutions. It will also devise and maintain standards for the professional organizations. A draft of Act of proposed PLIC is presented as an Appendix to this study for suggestions from LIS experts. It is recommended that a Committee may be formulated to review the draft before presenting it to the competent authorities.

The performance limits of conventional cooling technologies are being reached in both military and commercial electronics and electro-optical systems. Pumped Liquid Multiphase Cooling (PLMC) provides significantly enhanced thermal management capabilities for these systems using mostly-conventional components and working fluids. PLMC is highly scalable and reliable. Energy efficiency is very high, surpassing conventional techniques by up to two orders of magnitude. This paper describes the basic PLMC technology and presents experimental results from several prototype embodiments of the technology.

Streszczenie:

A comparative study has been carried out between different models of implementing surface tension for PLIC-VOF methods: i) the well known Continuum Surface Force (CSF); ii) Staggered Grid Interface Pressure (SGIP); iii) Modified Meier’s. As main difference with respect the CSF model, the two last use information of the interface location for the calculation of the surface tension forces, therefore, they need a model of interface reconstruction. The models will be tested under static and dynamic conditions, for the case of a drop and bubble between water and air. In order to reduce the ‘parasitic’ currents that is characteristic of this type of models, two different strategies are used: i) a new method for the calculation of the interface curvature based on the use of polar coordinates; ii) the use of kernels for smoothing the jump of the colour function and the interface. Additionally, the influence of the order of accuracy of the reconstruction algorithms employed that affect the curvature estimation and the surface tension force calculation is also checked. After testing the different cases, it can be concluded that SGIP and modified Meier perform in a comparable way, and much better than CSF model without kernel, that is only competitive with the use of the kernels. However, modified Meier is preferred respect SGIP due to its straitghforward implementation on unstructured meshes.

Streszczenie:

An efficient approach to handle either convex or non-convex arbitrary polytopes is applied to volume truncation and volume conservation enforcement operations involved in volume of fluid (VOF) methods. A comparison between the proposed approach and conventional procedures based on convex decomposition is carried out for different tests, demonstrating that the proposed tools represent a substantial improvement in computational efficiency. A speedup of around one order of magnitude is achieved for the reconstruction of several interfacial shapes. The non-convex tools have been used to implement a highly accurate volume of fluid (VOF) method based on a multidimensional advection scheme with edge-matched flux polyhedra and a piecewise linear interface calculation (PLIC) method. A preliminary analysis of the accuracy, computational efficiency and volume conservation properties of the implemented PLIC-VOF method is carried out.

Streszczenie:

Dramatically increased power dissipation in electronic and electro-optic devices has prompted the development of advanced thermal management approaches to replace conventional air cooling using extended surfaces. One such approach is Pumped Liquid Multiphase Cooling (PLMC), in which a refrigerant is evaporated in a cold plate in contact with the devices to be cooled. Heat is then rejected in an air or water-cooled condenser and the working fluid is returned to the cold plate. Reliable, highly efficient, small-scale components are required for the commercial application of this technology. This paper presents experimental results for two-phase meso-scale heat exchangers (cold plates) for use in electronics cooling. The configurations studied include single and multi-pass designs using R134a as the working fluid. With relatively low flow rates, low effective thermal resistances were achieved at power levels as high as 376 W. The results confirm the efficacy of PLMC technology for cooling the most powerful integrated circuits planned for the next decade.

Streszczenie:

Abstract Piecewise Linear Interface Calculation (PLIC) schemes have been extensively employed in the Volume-of-Fluid (VOF) method for interface capturing in numerical simulations of multiphase flows. Dynamic overset meshes can be especially useful in applications involving component motions and complex geometric shapes. The basic idea of the overset mesh is the variable field interpolation within the overlapped region between the background and body meshes. The acceptor cell value is evaluated by a weighted average of its donors. The weighting factors are calculated by different algebraic methods, such as the averageValue, injection and inverseDistance schemes, which are implanted in the foam-extend library. A geometric interpolation scheme of the VOF field in overset meshes for the PLIC-VOF method has been proposed in the present study. The VOF value of an acceptor cell is evaluated geometrically with the reconstructed interfaces from the corresponding donor elements. Test cases of advecting liquid columns of different shapes inside a unit square/cube with a prescribed rotational velocity field have been performed to demonstrate the accuracy of the proposed overset interpolation scheme by comparing it with three algebraic ones. The proposed scheme has been shown to yield higher accuracy.
