3D imaging of undissected optically cleared Anopheles stephensi mosquitoes and midguts infected with Plasmodium parasites

Niz, Mariana De ; Kehrer, Jessica ; Brancucci, Nicolas M. B. ; Moalli, Federica ; Reynaud, Emmanuel G. ; Stein, Jens V. ; Frischknecht, Friedrich

In: PLOS ONE, 2020, vol. 15, no. 9, p. e0238134

Malaria is a life-threatening disease, caused by Apicomplexan parasites of the Plasmodium genus. The Anopheles mosquito is necessary for the sexual replication of these parasites and for their transmission to vertebrate hosts, including humans. Imaging of the parasite within the insect vector has been attempted using multiple microscopy methods, most of which are hampered by the presence of...

Never and under cervical cancer screening in Switzerland and Belgium: trends and inequalities

Jolidon, Vladimir ; Prez, Vincent De ; Willems, Barbara ; Bracke, Piet ; Cullati, Stéphane ; Burton-Jeangros, Claudine

In: BMC Public Health, 2020, vol. 20, no. 1, p. 1517

Research on inequalities in cervical cancer screening (CCS) participation has overlooked the distinction between ‘never-’ and ‘under-screeners’ while different socioeconomic and demographic determinants may underlie ‘non-’ and ‘under-’ screening participation. This study examines socioeconomic and demographic inequalities in never and under CCS participation. We compare...

Ex vivo analysis of kidney graft viability using 31p magnetic resonance imaging spectroscopy

Longchamp, Alban ; Klauser, Antoine ; Songeon, Julien ; Agius, Thomas ; Nastasi, Antonio ; Ruttiman, Raphael ; Moll, Solange ; Meier, Raphael P. H. ; Buhler, Leo ; Corpataux, Jean-Marc ; Lazeyras, Francois

In: Transplantation, 2020, vol. 104, no. 9, p. 1825–1831

Background: The lack of organs for kidney transplantation is a growing concern. Expansion in organ supply has been proposed through the use of organs after circulatory death (donation after circulatory death [DCD]). However, many DCD grafts are discarded because of long warm ischemia times, and the absence of reliable measure of kidney viability. 31P magnetic resonance imaging (pMRI)...

Osteopathy in the French-speaking part of Switzerland: Practitioners’ profile and scope of back pain management

Bill, Anne-Sylvie ; Dubois, Julie ; Pasquier, Jérôme ; Burnand, Bernard ; Rodondi, Pierre-Yves

In: PLOS ONE, 2020, vol. 15, no. 5, p. e0232607

Background: Osteopathy is commonly used for spinal pain, but knowledge about back pain management by osteopaths is scarce.Objective: The aim of this study was to survey osteopaths across the French-speaking part of Switzerland about the scope of their practice and their management of patients with back pain.Design: This cross- sectional observational study was based on an online survey...

Essays on financial markets predictability

Pisati, Matteo Maria ; Barone Adesi, Giovanni (Dir.) ; Mira, Antonietta (Codir.)

Thèse de doctorat : Università della Svizzera italiana, 2020 ; 2020ECO007.

Empirical indicators of sentiment are commonly employed in the economic literature while a precise understanding of what is sentiment is still missing. Exploring the links among the most popular proxies of sentiment, fear and uncertainty this paper aims to fill this gap. We show how fear and sentiment are specular in their predictive power in relation to the aggregate market and to...

Essays in household finance and monetary policy transmission

Gianinazzi, Virginia ; Plazzi, Alberto (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2020 ; 2020ECO005.

This thesis consists of three chapters that contribute to two fundamental questions in finance: how households make financial decisions and how market prices react to uninformative demand shocks. The first chapter investigates how household respond to mortgage refinancing incentives. A well-documented finding in household finance is that many borrowers miss out on substantial savings by...

Asset prices and demand shocks

Barbon, Andrea ; Franzoni, Francesco (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2020 ; 2020ECO002.

My dissertation consists of three chapters, each of which focuses on a different area of research in asset pricing. The first chapter deals with the informational role of brokerage firms during fire sales in the equity market. The second chapter exploits the ETF program by the bank of Japan as a quasi-natural experiment to measure the slope of the equity demand curve. The last chapter presents...

Disruption of gamma–delta relationship related to working memory deficits in first-episode psychosis

Missonnier, Pascal ; Prévot, Anne ; Herrmann, François R. ; Ventura, Joseph ; Padée, Anna ; Merlo, Marco C. G.

In: Journal of Neural Transmission, 2020, vol. 127, no. 1, p. 103–115

Working memory (WM) deficits constitute a core symptom of schizophrenia. Inadequacy of WM maintenance in schizophrenia has been reported to reflect abnormalities in the excitation/inhibition (E/I) balance between pyramidal neurons and parvalbumin basket cells, which may explain alterations of the dynamics of gamma and delta oscillations. To address this issue, we assessed event-related gamma...

Multi-factorial approach to early numeracy—The effects of cognitive skills, language factors and kindergarten attendance on early numeracy performance of South African first graders

Aunio, Pirjo ; Korhonen, Johan ; Ragpot, Lara ; Törmänen, Minna ; Mononen, Riikka ; Henning, Elizabeth

In: International Journal of Educational Research, 2019, vol. 97, p. 65-76

The aim of the study was to investigate the influence of cognitive skills (executive function), language factors (listening comprehension, English as a second language, ESL) and kindergarten attendance on early numeracy in a cross-sectional sample of South African children (N=442) in the beginning of Grade 1. The mean age of children was 81.62 months (SD=5.40). Structural equation path models...

Low-load blood flow restriction training induces similar morphological and mechanical Achilles tendon adaptations compared with high-load resistance training

Centner, Christoph ; Lauber, Benedikt ; Seynnes, Olivier R. ; Jerger, Simon ; Sohnius, Tim ; Gollhofer, Albert ; König, Daniel

In: Journal of Applied Physiology, 2019, vol. 127, no. 6, p. 1660–1667

ow-load blood flow restriction (LL-BFR) training has gained increasing interest in the scientific community by demonstrating that increases in muscle mass and strength are comparable to conventional high-load (HL) resistance training. Although adaptations on the muscular level are well documented, there is little evidence on how LL-BFR training affects human myotendinous properties....
