The effectiveness and legitimacy of federal minority governments in Canada since 1945
Creators: name: Depner, Wolfgang
Publisher: name: University of British Columbia
Year: 2014

description: Despite popular expectations and theoretical predictions, Canada’s first-past-the- post electoral system continues to produce minority governments, defined by Forsey “as government by a cabinet with less than half of the seats in the House of Commons.” Since 1945, almost half of all federal elections have produced this form of government. Drawing instruction from the most recent run of minority governments between 2004 and 2011, the dissertation scrutinizes the effectiveness and legitimacy of the nine federal minority governments that have governed Canada since 1945. Methodologically, it treats them as probationary majorities and retroactively judges their effectiveness by whether they shed this status. Effectiveness, so understood, can in turn be explained by a number of different factors best seen through the prism of the prevailing Canadian party system. Turning to the question of legitimacy, the dissertation adopts a dualistic view of legitimacy in judging the surveyed minority governments by their (i) constitutional legitimacy and (ii) input legitimacy. Concerning the former, it argues that federal minority governments have historically played fast and loose with the constitutional conventions that sustain them. Concerning the latter, it argues further that minority governments have generally failed to improve the input legitimacy of parliamentary government, contrary to the position of Russell and others scholars who claim that minority government has the capacity to improve the ‘deliberative’ nature of the Commons. The present study challenges the claim of Russell and others in finding that minority government actually increases partisanship in discouraging genuine deliberation, as defined by theorists of deliberative democracy. It finds minority government nonetheless to be legitimate, according to Canada’s constitutional conventions.

description: UMS has developed an industrial power HBT process especially dedicated to power MMICs in the 10GHz frequency range. The process has been qualified and meets the very demanding specifications required for X-Band high power amplifiers. Aside from the obvious RF performances, this includes the demonstration of the necessary stability and reproducibility of the process, associated with state-of-art reliability. It is important to note that the later has been achieved without affecting the high frequency capability of the devices, and demonstrated directly on high power transistors. Thanks to its intrinsic qualities this process can naturally also be used for other applications, like low phase noise voltage controlled oscillators, and power amplifiers at lower frequencies (for mobile phones for instance).

description: This paper reviews the state of the art in overlapping community detection algorithms, quality measures, and benchmarks. A thorough comparison of different algorithms (a total of fourteen) is provided. In addition to community level evaluation, we propose a framework for evaluating algorithms' ability to detect overlapping nodes, which helps to assess over-detection and under-detection. After considering community level detection performance measured by Normalized Mutual Information, the Omega index, and node level detection performance measured by F-score, we reached the following conclusions. For low overlapping density networks, SLPA, OSLOM, Game and COPRA offer better performance than the other tested algorithms. For networks with high overlapping density and high overlapping diversity, both SLPA and Game provide relatively stable performance. However, test results also suggest that the detection in such networks is still not yet fully resolved. A common feature observed by various algorithms in real-world networks is the relatively small fraction of overlapping nodes (typically less than 30%), each of which belongs to only 2 or 3 communities.

description: Calystegine sind polyhydroxylierte Nortropanalkaloide, die vorwiegend in Solanaceaen und Convolvulaceaen vorkommen. In der Kartoffelpflanze (Solanum tuberosum L.) wurde die höchste Konzentration von Calysteginen in 1-3 mm langen Kartoffelkeimen gemessen. Das erste spezifische Enzym der Tropanalkaloid- und Nicotinbiosynthese ist die Putrescin-N-methyltransferase (PMT). Es wurde postuliert, dass Calystegine auf demselben Biosynthese-weg entstehen. N-Methylputrescin wurde in Kartoffelaugen, deren Dormanz gebrochen war (1,05 µmol/g TM) und in Kartoffelkeimen mit einer Länge von 1 mm (0,75 µmol/g TM) gemessen. Die Existenz einer PMT in Kartoffel konnte durch PMT-Aktivitätsmessungen in unterschiedlichen Kartoffelgeweben gezeigt werden. In 1 mm langen Kartoffelkeimen wurde eine spezifische Aktivität von 20 pkat/mg Protein gemessen. cDNA-Klone mit hoher Homologie zu bekannten Putrescin- N -methyltransferasen (PMT, EC 2.1.1.53) und Spermidinsynthasen (SPDS, EC 2.5.1.16) wurden isoliert. Rekombinante PMT- und SPDS-Proteine zeigten spezifische Enzymaktivitäten. Die Enym-charakteristika entsprachen denen bekannter PMT- und SPDS-Proteine. pmt-Transkript wurde ausschließlich in Kartoffelaugen zu Beginn der Keimung und in 1-3 mm langen Kartoffelkeimen gemessen, während spds-Transkrip in jedem untersuchten Gewebe gefunden wurde.
description: Calystegines are polyhydroxylated nortropane alkaloids that occur predominantly in Solanaceae and Convolvulaceae. The highest calystegine concentration in potato plant (Solanum tuberosum L.) was detected in 1-3 mm long potato sprouts. Putrescine-N-methyltransferase (PMT) is the first specific enzyme of tropane alkaloid and nicotine biosynthesis. It was postulated that calystegines develop on the same biosynthetic pathway. N-methylputrescine was detected in potato eyes start sprouting (1,05 µmol/g dm) and in 1 mm long potato sprouts (0,75 µmol/g dm). The existence of PMT in potato plants was shown by pmt activity measurements in different potato plant tissues. A specific PMT activity of 20 pkat/mg protein was detected in 1 mm long potato sprouts. cDNA clones with high homologies to known putrescine-N-methyltransferases (PMT, EC 2.1.1.53) and spermidine synthases (SPDS, EC 2.5.1.16) were isolated. Recombinant PMT and SPDS proteins show specific enzyme activities. The enzyme characteristics were similar to known PMT and SPDS proteins. pmt transcript was only detected in potato eyes start sprouting and in 1-3 mm long potato sprouts while spds transcript was found in every investigated tissue.

description: Four parameters are necessary for a complete characterization of the noise behavior of a linear device.The parameters can be experimentally determined by a minimum set of four equations,which can be obtained by an equal number of synthesized reflection coefficients at the input of the DUT,forming a pattern on the Smith chart.To increase the accuracy in the determination of the noise parameters,it is a common procedure to implement an heavily redundant pattern,with a random selection of more than the strictly necessary four points,so forcing the adoption of an expensive tuner.This paper introduces a novel ad hoc selected 4-points pattern,and demonstrates how it can simplify the measurement system without appreciably affecting the measurement accuracy.The proposed pattern is synthesized by easily realizable transmission lines,and a study has been performed to determine lines characteristics for use in wideband noise measurements.

description: Accurate simulation of PHEMT based GaAs MMIC ’s requires a bias dependent model that can be used in both small signal and large signal analysis and is accurate over a wide range of applied bias.The majority of models that are supplied with the commercial high frequency simulators have limitations that prevent this goal being achieved.The model areas that require attention are the symmetry of the model at drain-source voltages close to zero,use of the correct time delays within the device and a more precise inclusion of the bias dependent intrinsic noise processes.In this paper an approach to the generation of a large signal model is described that attempts to reconcile these requirements.

description: Hintergrund: Das anaplastische Schilddrüsenkarzinom ist ein hochmaligner Tumor mit einer mittleren Überlebenszeit von nur 6 Monaten. Das Ziel vorliegender Analyse ist die Frage nach dem Stellenwert der Strahlentherapie und Ergebnissen der trimodalen Therapie (OP, Radiatio, Chemotherapie). Methoden/Materiale: Vorliegend ist eine retrospektive Analyse der Akten und Bestrahlungsplänen aller im Zeitraum zwischen 1991 und 2008 an der Universitätsklinik und Poliklinik für Strahlentherapie in Halle behandelten ATC-Patienten. Erfasst wurden u.a. TNM-Stadium, Operations –und Bestrahlungsart. Ergebnisse: Von 40 Patienten unterzogen sich 97,5% einer Radiatio, 80% einer OP. Fernmetastasen bestanden bei Erstvorstellung bei 25%, das mediane Überleben betrug 5 Monate. Schlussfolgerung: Die Überlebensprognose ist beim ATC trotz einiger Langzeitüberlebender auch hier allgemein schlecht. Operabilität, ein Lymphknotentstatus N0 und eine Strahlendosis von >/=50 Gy sind prognostisch von Vorteil. Therapieansätze auf molekularer Ebene sollten weiterentwickelt werden
description: Background: The anaplastic thyroid carcinoma is an aggressive malignant tumor with median overall survival about 6 months. We analyzed the role of radiotherapy in the treatment of ATC and results of trimodal therapy (surgery, radiotherapy, chemotherapy). Methods: It is a retrospective analysis of all patients, who presented with histologically proven ATC at our centre between 1989 and 2008. We registered e.g. TNM-stadium, kind of surgery and radiotherapy. Results: 97.5% received radiation, 80% underwent surgery. At initial presentation in 25% of all distant metastasis were present. The median overall survival was 5 months. Conclusions: Although as expected prognosis of patients with anaplastic thyroid carcinoma is quite bad in our analysis, too, there have been cases of long term survival. Independent predictors of higher overall survival are absence of lymphnodemetastasis (N0), median dosis of radiation of 50 Gy or more and surgery. Anyway in future new therapeutic approachs targeting molecular processes should be investigated more intensively in large series to improve the prognosis of ATC.

description: This paper presents a non-linear p-HEMT model taking into account the non quasi-static currents and charges variations versus Vgs and Vds to predict accurate behaviour of the devices up to millimetric frequencies. The major refinement of this model concerns the introduction of voltage dependant 2 nd order frequency coeficients (1 st order non quasi-static terms) generally considered constant or partially variable in previous published models. The non quasi-static ehaviour of the transistor is modelled by time second derivatives of non-linear functions Ags(vgs,vds) and  Ads(vgs,vds) integrated from linear 2 ndorder frequency coefficients. Classical method are used to extract non-linear elements from pulsed S-parameters and current measurement set-up [1]. Most of the voltage dependant coefficients (currents, charges and non-quasi-static terms) are precisely fitted with bicubic spline functions for very accurate description. This model has been implemented in commercial balance harmonic software. Ags and Ads tim  second derivatives are generated partially in the non-linear part of the model (time first derivative considered as charge derivative) and partially with a linear sub-circuit (second derivative). This model would predict more accurate 2nd and 3 rd harmonics behaviour for applications at fundamental frequencies up to 20 GHz.

description: In addition to agronomic importance, as one of the best predecessors, peas provide significant economic efficiency. The constant rise in prices for mineral fertilizers, plant protection products, fuel, etc. leads to in-creased costs of cultivation and reduced profits from the sale of peas. Therefore, it is predominant not only to achieve a high level of yield but also to improve economic efficiency. Given that the control variant used min-eral fertilizers in the norm N30Р60К60 and pre-sowing treatment of seeds with an inoculant, the lion's share of costs compared to other variants is the background of the control variant, which has been essentially superim-posing on added variants. However, the low profitability of the control option is the cause of high costs for mineral fertilizers, and a small gradual increase in yield due to seed treatment with trace elements, soil liming, foliar fertilization is quite understandable in increasing the profitability of growing peas. The most important indicator of economic efficiency is profit. The economic efficiency of growing vegetable peas has been charac-terizing by positive results in all variants of the experiment. This indicator was the lowest in the control (7553-8601 and 11989-12630 UAH / ha), it was higher in the second, as well as the third and fourth versions of the research (8596-9644 and 13020-13673 UAH / ha); 14399 UAH / ha); (10548-11517 and 14814-15862 UAH / ha). That is, with the increase in the level of yield due to the intensification of the technology of growing crops, the profit of the extension products gradually increases. Reaching its maximum in the fourth version of the study, due to the synergistic interaction of nutrients, the return on fertilizers increases. The high yield of vege-table peas, which accumulated the highest energy values 12.55 and 14.87 million kcal provided a high coef-ficient of energy efficiency in our research, which was 3.36 in Skinado and 3.99 in Somerwood.

description: Protocols developed during the last years for Wireless Sensor Networks (WSNs) are mainly focused on energy efficiency and autonomous mechanisms (e.g. self-organization, self-configuration, etc). Nevertheless, with new WSN applications, appear new QoS requirements such as time constraints. Real-time applications require the packets to be delivered before a known time bound which depends on the application requirements. We particularly focus on applications which consist in alarms sent to the sink node. We propose Real-Time X-layer Protocol (RTXP), a real-time communication protocol. To the best of our knowledge, RTXP is the first MAC and routing real-time communication protocol that is not centralized, but instead relies only on local information. The solution is cross-layer (X-layer) because it allows to control the delays due to MAC and Routing layers interactions. RTXP uses a suited hop-count-based Virtual Coordinate System which allows deterministic medium access and forwarder selection. In this paper we describe the protocol mechanisms. We give theoretical bound on the end-to-end delay and the capacity of the protocol. Intensive simulation results confirm the theoretical predictions and allow to compare with a real-time centralized solution. RTXP is also simulated under harsh radio channel, in this case the radio link introduces probabilistic behavior. Nevertheless, we show that RTXP it performs better than a non-deterministic solution. It thus advocates for the usefulness of designing real-time (deterministic) protocols even for highly unreliable networks such as WSNs.

description: Recently proposed,general-purpose mathematical approaches,such as the Finite Memory Model (FMM)[6 ]and the Non-linear Discrete Convolution Model (NDC)[7 ],are used for the nonlinear modeling of electron devices. Both models derive from the same theoretical approach and are identi ﬁed on the basis of conventional DC (and/or pulsed characteristics)and small-signal differential parameter measurements. The implementation of the two models in the framework of the Agilent-ADS CAD package is described in the paper and a wide experimental validation,including small-and large-signal results,is presented for GaAs- MESFET,and PHEMT devices.

description: A promising task of green construction is to replenish the quantitative and species composition of orna-mental plants in order to improve botanical gardens and parks, which are the key to modern urban landscap-ing. The current state of use of ornamental and valuable plants of the genus Iris L. in the Podillya zone to de-termine their prospects for landscaping the park zone of Vinnytsia National Agrarian University has been stud-ied. Expansion of the collection of flowering plants in green construction due to the preservation of their gene pool will allow to study the selection of introduced species, varieties and hybrids adapted to the conditions of the growing area with the development of modern principles of their use in landscaping. According to the re-sults of research of existing and introduced plants of Iris L. in Vinnytsia region, it is proposed to use in land-scaping varieties and hybrids of these plants, which are characterized by high criteria for a set of morphologi-cal and economic-biological characteristics. The most promising varieties of foreign selection for the creation of the Iris L. collection on the basis of the architectural and exposition section of the Department of Forestry, Horticulture, Horticulture and Viticulture of the Faculty of Agronomy and Forestry have been studied. Sum-mary of recommendations for the use of promising cultivars of foreign selection in green construction, taking into account their biological and ecological and morphological features. It is investigated that the study of varietal diversity of Iris L. allows to significantly expand the knowledge about their adaptive properties and use in different areas of floriculture in the Podillya area, as well as in selection work. It is determined that from the scientific and practical point of view the researched collection fund is perspective for creation of flower beds, borders, groups on a lawn background, mixborders and is an excellent material for creation of garden compositions. It is proved that the expansion of variants of modern decorative compositions with their partici-pation will give the park zone of Vinnytsia NAU a more spectacular look.

A canonical genus four curve is a complete intersection of a quadric and a cubic, and, in contrast to the genus three case, there is a family of GIT quotients that depend on a choice of linearization. We discuss the corresponding VGIT problem and show that the resulting spaces give the final steps in the Hassett-Keel program for genus four curves.

A cellar tropic : elision and the marijuana worker
Creators: name: McCann, Clayton
Publisher: name: University of British Columbia
Year: 2014

description: The marijuana worker is absent from public discourse. The following thesis will illustrate this fact. While it is indeed difficult to collect data on illicit industries like (non-medical) marijuana production, it is curious that the default representation of marijuana workers and their employers or, for the purposes of this context, growers, is either that of a gang member or an invisible, non-subject. Ongoing, radical changes in marijuana production social labour and the surrounding socio-legal environment in Canada, the United States and beyond have wide-ranging effects in store for British Columbian industry workers and growers. Tracking relevant discourse and assessing typical representations of marijuana growers and workers in media and popular culture products reveal the ongoing construction of abject identities: malingering medical clients employing natural remedies of questionable efficacy, violent gangsters, community-destroying hooligans, and exoticized products of alterity, the hyper-racialized ethnic other. Extended periods of participant observation in multiple marijuana production sectors familiarize the ethnographer with an altogether different cast of characters: peaceful men and women working full or part time as entrepreneurial owner/operators or workers struggling to favorably balance the risk/reward ratio. The project of comparing the resulting divergent representations and discourse⎯the armed Hell’s Angels grower you meet in the newspaper versus the single mom grower you find in her garden⎯is important as nascent structural changes threaten this occupational category in both the illicit and legal sectors. Creative re-representations found throughout are a result of participant observation-based autobiography and autoethnography methods, intended to contribute to new understandings of these hidden peoples, their life-ways and communities.

description: A modular neural network architecture for accurate small/large signal microwave MESFET/HEMT modeling is presented. This is achieved by means of an original neural architecture having two main modules. A network captures the nonlinear dynamic Pulsed I/V characteristic of the device, which is mainly responsible of the large signal behavior, while the second network estimates the high order derivatives at the operation point, which are responsible of the IMD behaviour, by means of a neural network and then it locally reconstructs the current function by means of a third order Taylor series around that point. Finally, in order to have a maximum of coherence, the two networks are combined into a global model by means of a simple fuzzy controller. Computer simulations and experimental measurements validate this flexible modeling technique.

We show that E is contained in the isotropic cone of the bilinear form B associated to a geometric representation, and illustrate this property with numerous examples and pictures in rank 3 and 4. We also define a natural geometric action of W on E, and then we exhibit a countable subset of E, formed by limit points for the dihedral reflection subgroups of W. We explain that this subset is built from the intersection with Q of the lines passing through two positive roots, and finally we establish that it is dense in E.

description: We consider a nonlinear structured population model with a distributed recruitment term. The question of the existence of non-trivial steady states can be treated (at least!) in three different ways. One approach is to study spectral properties of a parametrized family of unbounded operators. The alternative approach, on which we focus here, is based on the reformulation of the problem as an integral equation. In this context we introduce a density dependent net reproduction rate and discuss its relationship to a biologically meaningful quantity. Finally, we briefly discuss a third approach, which is based on the finite rank approximation of the recruitment operator.

description: We present a model for theoretical description of the dynamics of a system of spinor cavity polaritons in real space and time accounting for all relevant types of the interactions and effective magnetic fields. We apply our general formalism for the consideration of the polarization dynamics of the coherently driven one dimensional polariton channel. We investigate effect of the temperature and the longitudinal-transverse splitting on the spin (polarization) multistability and hysteresis arising from the polarization-dependent polariton-polariton interaction. We show that the effect of the phase of the driving laser pump is as important as its strength and demonstrate that the multistability behavior can survive up to high temperatures in presence of longitudinal-transverse splitting.

description: a) Incendio e caso fortuito: rilevanza delle misure precauzionali adottate.
Per andare esente da responsabilità il custode deve individuare, positivamente, il caso fortuito, ossia l’intervento di un fattore esterno di per sé solo capace di produrre l’eventus damni, onde restano a suo carico le c.d. «cause ignote».
Gli eventi naturali possono integrare, sempreché imprevedibili ed inevitabili, il fortuitus; ma la loro semplice eccezionalità, di per sé sola, non è sufficiente ad escludere la responsabilità, dovendosi anche valutare (congiuntamente) il comportamento adottato dal custode, essendo a questi richiesto di adoperarsi mediante l’adozione di tutte le misure precauzionali che, in relazione allo stato della cosa, alla sua destinazione e alle circostanze del caso concreto, appaiono ordinariamente idonee a tutelare i terzi da pregiudizi.

b) Le ondivaghe posizioni della giurisprudenza della natura dolosa dell’incendio.
Recentemente la giurisprudenza ha osservato che l’accertamento della natura dolosa dell’incendio non è, di per sé, sufficiente a fornire la prova liberatoria a favore del custode, qualora il relativo procedimento penale sia stato archiviato per essere rimasti ignoti i responsabili; in altre pronunce, invece, il custode è stato assolto, anche in mancanza di identificazione del responsabile, ritenendosi sufficiente la prova dell’attività del terzo, sì da permettere l’imputazione a questi dell’evento.

c) Incendio di veicolo in sosta: responsabilità ex art. 2051 c.c. o ex art. 2054 c.c.?
Esulano dall’ambito di applicazione dell’art. 2051 c.c., i beni per i quali il legislatore ha individuato una disciplina specifica, come è per i mezzi adibiti al trasporto terrestre a guida libera, che trovano puntuale normazione nell’art. 2054 c.c. Qualora, tuttavia, il danno non sia in alcun modo collegabile, causalmente, alla circolazione stradale, intesa quale utilizzazione della via pubblica o della strada privata aperta al pubblico, compresa la sosta del mezzo, il regime della responsabilità è quello, generale, previsto per le cose in custodia, e non quello della disciplina specifica.

description: The article defines that the economic potential of any country largely depends on the state of its energy resources and the conditions of their use. It is substantiated that reliable, stable and efficient provision of the world economy with energy resources is a guarantee of energy security and an indicator of the quality of life of the population. The analysis of the world experience of innovation and investment directions of develop-ment of alternative energy sources is carried out. It is determined that for the sake of sustainable economic development of countries it is necessary to actively develop the use of alternative energy sources and energy efficiency. The necessity of transition to innovative ways of using alternative energy sources, which have huge resources and reduce the negative impact of energy on the environment, in order to ensure the stable develop-ment of both domestic and global economies. The adoption of the world experience of stimulating the use of alternative energy sources is proposed and the necessity of its adaptation to the modern conditions of Ukraine 's development is substantiated, applying a wide range of ways of stimulating the use of alternative energy sources.

description: Granular materials, whose features range from the particle scale to the force-chain scale to the bulk scale, are usually modeled as either particulate or continuum materials. In contrast with either of these approaches, network representations are natural for the simultaneous examination of microscopic, mesoscopic, and macroscopic features. In this paper, we treat granular materials as spatially-embedded networks in which the nodes (particles) are connected by weighted edges obtained from contact forces. We test a variety of network measures for their utility in helping to describe sound propagation in granular networks and find that network diagnostics can be used to probe particle-, curve-, domain-, and system-scale structures in granular media. In particular, diagnostics of meso-scale network structure are reproducible across experiments, are correlated with sound propagation in this medium, and can be used to identify potentially interesting size scales. We also demonstrate that the sensitivity of network diagnostics depends on the phase of sound propagation. In the injection phase, the signal propagates systemically, as indicated by correlations with the network diagnostic of global efficiency. In the scattering phase, however, the signal is better predicted by meso-scale community structure, suggesting that the acoustic signal scatters over local geographic neighborhoods. Collectively, our results demonstrate how the force network of a granular system is imprinted on transmitted waves.

description: In der vorliegenden Arbeit wird die säulenchromatographische Reinigung einer Peptidyl-Prolyl-cis/trans-Isomerase (PPIase) aus Pflanzen, speziell aus Proembryogenen Massen (PEMs) von Digitalis lanata beschrieben. Diese, zur Familie der phosphospezifischen Parvuline gehörende PPIase bevorzugt Peptidsubstrate, die das Motiv pThr/pSer-Pro aufweisen. Weiterhin wird die Klonierung, die heterologe Expression und die biochemische Charakterisierung von DLPar12.8 dargestellt. Durch erste nähere Aussagen, z.B. über Substratspezifität, Inhibierbarkeit und Verteilung in der Pflanze, sollte ein Vergleich mit bereits bekannnten Vertretern der phospho-spezifischen Parvuline ermöglicht werden. Im Gegensatz zu diesen bereits bekannten Vertretern der phosphospezifischen Parvuline zeichnet sich DLPar12.8 durch das Fehlen einer Phosphopeptide bindenden WW-Domäne aus. Es konnte gezeigt werden, daß trotz des Fehlens der WW-Domäne DLPar12.8 vermutlich eine ähnliche Funktion ausübt, wie das humane Pin1 bzw. ESS1 aus Hefe.
description: A peptidyl-prolyl cis/trans isomerase (PPIase) was isolated from proembryogenic masses (PEMs) of Digitalis lanata according to its enzymatic activity. Partial sequence analysis of the purified enzyme (DLPar12.8) revealed sequence homology to members of the parvulin family of PPIases. Similar to human Pin1 and yeast Ess1, it exhibits catalytic activity towards substrates containing pThr/pSer-Pro peptide bonds and comparable inhibition kinetics with juglone. Unlike Pin1-type enzymes it lacks the phosphopeptide binding WW-domain. Western blotting with anti-DLPar12.8 serum recognized the endogenous form in the cytosolic fraction of the plant cells. Since the PIN1 homologue ESS1 is an essential gene, complementation experiments in yeast were peformed. It reveals that DLPar12.8 is almost as effective as the nuclear hPin1 in rescuing the temperature sensitive phenotype of the Saccharomyces cerevisiae strain, which is caused by a mutation in ESS1. In contrast, the human parvulin hPar14 is not able to rescue the lethal phenotype of this yeast strain at non-permissive temperatures. These results suggest a function for DLPar12.8 rather similar to parvulins of the Pin1-type.
Chronic Inflammation as the Mechanistic Link between Type 2 Diabetes Mellitus and Alzheimer's Disease

description: Recent research has identified type 2 diabetes mellitus (T2DM) as a risk factor for neurodegenerative disorders such as Alzheimer’s disease (AD). However, the mechanisms involved in this interaction still remain unclear. Chronic neuroinflammation caused by activation of glial cells in the brain contributes to neuronal loss and disease progression in AD. This thesis investigated if chronic inflammation could be a mechanistic link responsible for increasing the risk of AD in individuals with T2DM. Specifically, I hypothesized that high levels of glucose and the phenomenon of insulin resistance observed in T2DM could accelerate neuronal loss and eventually lead to AD by increasing glial cell activation and/or enhancing neuronal injury caused by disease-specific agents. Since astrocytes are the most abundant glial cell type in the brain, in vitro experiments were conducted using primary human astrocytes and U-118 MG human astrocytic cells as models of primary astrocytes. I found that supernatants of astrocytic cells incubated in high glucose (30.5 mM) were more toxic to neuronal cells pre-treated with high glucose compared to supernatants of astrocytic cells incubated in low glucose (5.5 mM). High glucose increased mRNA expression of the pro-inflammatory cytokine interleukin (IL)-6 and enhanced secretion of both IL-6 and IL-8 by all astrocytic cells. Data obtained indicated that increased activation of the p38 mitogen activated protein kinase (MAPK) may be mediating the effects of high glucose in astrocytic cells. In addition, high glucose increased the susceptibility of undifferentiated human SH-SY5Y neuronal cells and retinoic-acid differentiated SH-SY5Y cells to injury by hydrogen peroxide and fibrillar amyloid beta-42 protein (Aβ42), respectively. Human primary glial cells and astroglial cell lines expressed the insulin receptor (INSR) and its signaling components. Moreover, insulin was found to modulate secretion of pro-inflammatory cytokines by primary human astrocytes with 1nM insulin concentration causing maximum enhancement of IL-6 and IL-8 secretion. Therefore, high glucose and insulin levels in T2DM could contribute to an early appearance of AD-like symptoms by increasing glial cell-mediated inflammation. This research highlights novel mechanisms responsible for AD progression and could help identify new preventative and treatment strategies for AD.
