Paracrine effect of membrane vesicles released by mouse mesoangioblast stem cells

2016

Introduction: Mouse mesoangioblasts are vessel-associated multipotent progenitor stem cells, which are able to differentiate into different mesodermal cell types. In our previous paper, we have demonstrated that mesoangioblasts are able to shed in the extracellular environment membrane vesicles (EVs), which contain both structural proteins and biological factors such as FGF2 and the two gelatinases MMP2/9. We investigated whether these EV interact in a paracrine way with other cell types different from mesoangioblasts, and eventually the effects of this interaction. Methods: Mesoangioblast EVs were collected from conditioned media by ultracentrifugation. Total mRNAs from mesoangioblasts and…

Sorbenty i membrany polimerowe w analizie środowiskowej

2003

Zwiększające się zanieczyszczenie środowiska wynikające z działalności człowieka, powoduje konieczność stałego jego monitorowania, a tym samym poszukiwania efektywnych i czułych metod analizy. Istotnym elementem wszystkich procedur analitycznych, a szczególnie w analizie substancji występujących w wieloskładnikowych skomplikowanych mieszaninach, jest wstępne wydzielenie, oczyszczenie i zatężenie próbki. Do tego celu, w ostatnim czasie, coraz częściej używa się sorbentów polimerowych lub układów membranowych. W niniejszym przeglądzie przedstawiono najważniejsze metody przygotowania próbek środowiskowych do analizy: ekstrakcję na fazie stałej (SPE) oraz procesy membranowe.

Observation of the rare decay K-S -> pi(0)e(+)e(-)

2003

A search for the decay Ks->pi0e+e- has been made by the NA48/1 experiment at the CERN SPS accelerator. Using data collected during 89 days in 2002 with a high-intensity Ks beam, 7 events were found with a background of 0.15 events. The branching fraction BR(Ks->pi0e+e-, m(ee) > 0.165 GeV/c^2) = (3.0^{+1.5}_{-1.2}(stat) +/-0.2 (syst)) x 10^{-9} has been measured. Using a vector matrix element and a form factor equal to one, the measurement gives BR(Ks->pi0e+e-) = (5.8^{+2.9}_{-2.4}) x 10^{-9}.

Observation of the decay KS→π+π−e+e−

2000

Abstract We present the first observation of the decay KS→π+π−e+e− based upon the data collected in 1998 by the NA48 experiment at CERN. We have identified a clean sample of 56 events with negligible background contamination. Using KL→π+π−π0D decays as normalization sample, the branching ratio is measured to be BR(KS→π+π−e+e−)=[4.5±0.7(stat)±0.4(syst)]×10−5. This result is in good agreement with the theoretical expectations from the mechanism of inner bremsstrahlung.

Understanding the Role of Social Media Content in Brand Loyalty: A Meta-Analysis of User-Generated Content Versus Firm-Generated Content

2023

The enormous growth of social media has increased interest in this platform among marketers and marketing academics. However, the previous literature has not provided a clear consensus regarding the influence of social media content on consumers’ brand loyalty. The meta-analysis presented in this article integrates results from 223 independent samples, with a total of 97,709 respondents. The study synthesizes previous research to develop a conceptual framework around the dimensions of brand loyalty (cognitive, affective, and conative loyalty), user-generated and firm-generated social media content attributes, and the moderating effects of contextual characteristics and control variables. S…

Existence of optimal transport maps in very strict CD(K,∞) -spaces

2018

We introduce a more restrictive version of the strict CD(K,∞) -condition, the so-called very strict CD(K,∞) -condition, and show the existence of optimal maps in very strict CD(K,∞) -spaces despite the possible lack of uniqueness of optimal plans. peerReviewed

Non-branching geodesics and optimal maps in strong CD(K,∞) -spaces

2014

We prove that in metric measure spaces where the entropy functional is Kconvex along every Wasserstein geodesic any optimal transport between two absolutely continuous measures with finite second moments lives on a non-branching set of geodesics. As a corollary we obtain that in these spaces there exists only one optimal transport plan between any two absolutely continuous measures with finite second moments and this plan is given by a map. The results are applicable in metric measure spaces having Riemannian Ricci curvature bounded below, and in particular they hold also for Gromov-Hausdorff limits of Riemannian manifolds with Ricci curvature bounded from below by some constant. peerReview…

International Society for Extracellular Vesicles: first annual meeting, April 17-21, 2012: ISEV-2012

2012

Extracellular micro- and nano-scale membrane vesicles produced by different cells are recognized as an essential entity of physiological fluids in a variety of organisms and function as mediators of intercellular communication employed for the regulation of multiple systemic and local processes. In the last decade, an exponential amount of experimental work was dedicated to exploring the biogenesis and secretion mechanisms, physiological and pathological functions and potential applications of the extracellular vesicles (EVs). Noteworthy is the large heterogeneity of in vitro and in vivo models applied, technical approaches developed in these studies and the diversity of designations assign…

Hvorfor kan vi ikke bare slutte med olje? : en retorisk analyse av Statoils kommunikasjon av miljøansvar

2016

Masteroppgave samfunnskommunikasjon- Universitetet i Agder, 2016 I denne masteroppgaven ser jeg nærmere på hvordan Statoil kommuniserer miljøansvar, og hvilke retoriske strategier Statoil tar i bruk i en utvalgt reklameserie. Oppgaven tar for seg hvordan Statoil tar i bruk de tre retoriske appellformene ethos, logos og pathos for å overbevise sine mottakere og fremstå troverdige. Her vil jeg undersøke hvordan de kommuniserer miljøansvar og hvilke av de tre appellformene Statoil tar i bruk når de adresserer dette temaet. Tematikken miljøansvar i oljebransjen er viktig å undersøke slik at forbrukere kan se gjennom oljeaktørers retorikk og ta bevisste valg og bli bevisste forbrukere. Klimaendr…
