Lack of evidence for regulation of cardiac P-type ATPases and MAP kinases in transgenic mice with cardiac-specific overexpression of constitutively active α1B-adrenoceptors

The regulatory function of α1B-adrenoceptors in mammalian heart homeostasis is controversial. The objective of the present study was to characterize the expression/activity of key proteins implicated in cardiac calcium handling (Na+/K+-ATPase and Ca2+-ATPases) and growth (ERK1/2, JNK1/2 and p38) in mice with cardiac-selective overexpression of constitutively active mutant α1B-adrenoceptor (CAMα1B-AR), which present a mild cardiac hypertrophy phenotype. Immunoblot assays showed that myocardial plasma membrane Ca2+-ATPase (PMCA) expression was increased by 30% in CAMα1B-AR mice (N = 6, P < 0.05), although there was no change in sarco/endoplasmic reticulum Ca2+-ATPase (SERCA2) expression. Moreover, total Ca2+-ATPase activity was not modified, but a significant increase in the activity of the thapsigargin-resistant (PMCA) to thapsigargin-sensitive (SERCA) ratio was detected. Neither Na+/K+-ATPase activity nor the expression of α1 and α2 subunit isoforms was changed in CAMα1B-AR mouse hearts. Moreover, immunoblot assays did not provide evidence for an enhanced activation of the three mitogen-activated protein kinases studied in this stage of hypertrophy. Therefore, these findings indicate that chronic cardiac α1B-AR activation in vivo led to mild hypertrophy devoid of significant signs of adaptive modifications concerning primary intracellular calcium control and growth-related proteins, suggesting a minor pathophysiological role of this adrenergic receptor in mouse heart at this stage of development.

Reversible flow of cholesteryl ester between high-density lipoproteins and triacylglycerol-rich particles is modulated by the fatty acid composition and concentration of triacylglycerols

We determined the influence of fasting (FAST) and feeding (FED) on cholesteryl ester (CE) flow between high-density lipoproteins (HDL) and plasma apoB-lipoprotein and triacylglycerol (TG)-rich emulsions (EM) prepared with TG-fatty acids (FAs). TG-FAs of varying chain lengths and degrees of unsaturation were tested in the presence of a plasma fraction at d > 1.21 g/mL as the source of CE transfer protein. The transfer of CE from HDL to FED was greater than to FAST TG-rich acceptor lipoproteins, 18% and 14%, respectively. However, percent CE transfer from HDL to apoB-containing lipoproteins was similar for FED and FAST HDL. The CE transfer from HDL to EM depended on the EM TG-FA chain length. Furthermore, the chain length of the monounsaturated TG-containing EM showed a significant positive correlation of the CE transfer from HDL to EM (r = 0.81, P < 0.0001) and a negative correlation from EM to HDL (r = -041, P = 0.0088). Regarding the degree of EM TG-FAs unsaturation, among EMs containing C18, the CE transfer was lower from HDL to C18:2 compared to C18:1 and C18:3, 17.7%, 20.7%, and 20%, respectively. However, the CE transfer from EMs to HDL was higher to C18:2 than to C18:1 and C18:3, 83.7%, 51.2%, and 46.3%, respectively. Thus, the EM FA composition was found to be the rate-limiting factor regulating the transfer of CE from HDL. Consequently, the net transfer of CE between HDL and TG-rich particles depends on the specific arrangement of the TG acyl chains in the lipoprotein particle core.

Rat vas deferens SERCA2 is modulated by Ca2+/calmodulin protein kinase II-mediated phosphorylation

Ca2+ pumps are important players in smooth muscle contraction. Nevertheless, little information is available about these pumps in the vas deferens. We have determined which subtype of sarco(endo)plasmic reticulum Ca2+-ATPase isoform (SERCA) is expressed in rat vas deferens (RVD) and its modulation by calmodulin (CaM)-dependent mechanisms. The thapsigargin-sensitive Ca2+-ATPase from a membrane fraction containing the highest SERCA levels in the RVD homogenate has the same molecular mass (∼115 kDa) as that of SERCA2 from the rat cerebellum. It has a very high affinity for Ca2+ (Ca0.5 = 780 nM) and a low sensitivity to vanadate (IC50 = 41 µM). These facts indicate that SERCA2 is present in the RVD. Immunoblotting for CaM and Ca2+/calmodulin-dependent protein kinase II (CaMKII) showed the expression of these two regulatory proteins. Ca2+ and CaM increased serine-phosphorylated residues of the 115-kDa protein, indicating the involvement of CaMKII in the regulatory phosphorylation of SERCA2. Phosphorylation is accompanied by an 8-fold increase of thapsigargin-sensitive Ca2+ accumulation in the lumen of vesicles derived from these membranes. These data establish that SERCA2 in the RVD is modulated by Ca2+ and CaM, possibly via CaMKII, in a process that results in stimulation of Ca2+ pumping activity.

Map matching by using inertial sensors: literature review

This literature review aims to clarify what is known about map matching by using inertial sensors and what are the requirements for map matching, inertial sensors, placement and possible complementary position technology. The target is to develop a wearable location system that can position itself within a complex construction environment automatically with the aid of an accurate building model. The wearable location system should work on a tablet computer which is running an augmented reality (AR) solution and is capable of track and visualize 3D-CAD models in real environment. The wearable location system is needed to support the system in initialization of the accurate camera pose calculation and automatically finding the right location in the 3D-CAD model. One type of sensor which does seem applicable to people tracking is inertial measurement unit (IMU). The IMU sensors in aerospace applications, based on laser based gyroscopes, are big but provide a very accurate position estimation with a limited drift. Small and light units such as those based on Micro-Electro-Mechanical (MEMS) sensors are becoming very popular, but they have a significant bias and therefore suffer from large drifts and require method for calibration like map matching. The system requires very little fixed infrastructure, the monetary cost is proportional to the number of users, rather than to the coverage area as is the case for traditional absolute indoor location systems.

Paper- and membrane-based ion-modulated electronics

Avhandlingen handlar om pappers- och membranbaserad jonmodulerad elektronik. Målet med forskningen har varit att utveckla billig, miljövänlig och brännbar elektronik, som kan användas i vardagliga engångsprodukter. Baskomponenterna som utvecklas och presenteras i avhandlingen är transistorer och kondensatorer. Mer komplicerad logisk kretselektronik demonstreras också med hjälp av dessa komponenter. Substraten som utnyttjas vid framställningen av dessa elektroniska komponenter är papper och membran. Dessa substrat är flexibla, hållbara, billiga, miljövänliga, etc. och därför väl anpassade för befintliga tryckteknologier. Själva baskomponenterna framställs sedan på dessa substrat genom att trycka flera skikt på varandra, där varje enskilt skikt är ett individuellt material. Detta är möjligt eftersom de organiska materialen som används i dessa komponenter är upplösta i ett lösningsmedel och kan därmed tryckas på samma sätt som ett vanligt bläck. Ett tredimensionellt objekt kan på detta sätt framställas. I avhandlingen presenteras flera olika typer av transistorer, men den gemensamma nämnaren bland dessa är att isolatorn är en jonledare. Denna, ganska ovanliga, transistormodellen har den stora fördelen att lågspänningskomponenter kan relativt enkelt framställas. Det som är speciellt med våra transistorer är att vi har använt miljövänliga jonledare. Detta, bl.a., leder till att våra komponenter visar både god prestanda, tillika som de är miljövänliga. I avhandlingen demonstrerar vi även tryckta superkondensatorer, en motsvarighet till laddningsbara batterier, konstruerade på papper med aktiverat kol och miljövänliga jonledare. De mest komplicerade logiska kretsar som demonstreras i denna avhandling är ring-oscillatorer och 1-bits-minnen konstruerade på papper. --------------------------------------------- Väitöskirja käsittelee paperille ja polymeerikalvolle tulostettua ionimoduloitua elektroniikkaa. Tutkimuksen tavoitteena oli kehittää edullista, ympäristöystävällistä ja polttokelpoista elektroniikkaa, jota voidaan käyttää esim. tavanomaisissa kertakäyttötuotteissa. Väitöskirjassa esitellään erilaisia transistoreita ja kondensaattoreita. Näitä elektronisia peruskomponentteja käyttäen demonstroidaan myös monimutkaisempia loogisia piirejä. Komponenttien valmistuksessa alustana käytettiin paperia ja polymeerikalvoa. Valitut alustat ovat joustavia ja kestäviä, ja ovat siksi hyvin yhteensopivia olemassa olevien tulostusmenetelmien kanssa. Peruskomponentit valmistettiin tulostamalla eri materiaaleja päällekkäin. Komponenteissa käytettävät orgaaniset aineet ovat liuenneessa muodossa musteessa, joka voidaan tulostaa samalla periaatteella kuin mikä tahansa normaali muste. Tällä menetelmällä voidaan valmistaa myös kolmiulotteisia tuotteita. Väitöskirjassa esitellään useita erityyppisiä transistoreita, joissa yhdistävänä tekijänä on ionisesti johtava eriste. Tällaista suhteellisen harvinaista transistorityyppiä käyttämällä voidaan mahdollistaa matala-jännitteisten komponenttien yksinkertainen valmistus. Valmistettujen transistoreiden etu on ionisten nesteiden ympäristöystävällisyys. Elektroniset komponentit ovat täten hyviä suorituskyvyltään, mutteivät haitallisia ympäristölle. Väitöskirjassa demonstroidaan myös tulostettujen superkondensaattoreiden, eli ladattavien paristojen vastineiden, valmistus paperille aktiivihiiltä ja ionisia nesteitä käyttäen. Kaikkein monimutkaisimmat loogiset piirit, jotka tässä väitöskirjassa esitellään, ovat rengasoskillaattorit sekä 1-bittinen paperille valmistettu muisti.

Visual Customer Segmentation and Data Exploration with the Self-Organizing Map

Advancements in information technology have made it possible for organizations to gather and store vast amounts of data of their customers. Information stored in databases can be highly valuable for organizations. However, analyzing large databases has proven to be difficult in practice. For companies in the retail industry, customer intelligence can be used to identify profitable customers, their characteristics, and behavior. By clustering customers into homogeneous groups, companies can more effectively manage their customer base and target profitable customer segments. This thesis will study the use of the self-organizing map (SOM) as a method for analyzing large customer datasets, clustering customers, and discovering information about customer behavior. Aim of the thesis is to find out whether the SOM could be a practical tool for retail companies to analyze their customer data.
